Fundamental Aspects of Plasma Chemical Physics: Tranpsort develops basic and advanced concepts of plasma transport to the modern treatment of the Chapman-Enskog method for the solution of the Boltzmann transport equation. The book invites the reader to consider actual problems of the transport of thermal plasmas with particular attention to the derivation of diffusion- and viscosity-type transport cross sections, stressing the role of resonant charge-exchange processes in affecting the diffusion-type collision calculation of viscosity-type collision integrals. A wide range of topics is then discussed including (1) the effect of non-equilibrium vibrational distributions on the transport of vibrational energy, (2) the role of electronically excited states in the transport properties of thermal plasmas, (3) the dependence of transport properties on the multitude of Saha equations for multi-temperature plasmas, and (4) the effect of the magnetic field on transport properties.

Ibraheem, Omodele; Botha, Christiaan E J; Bradley, Graeme

2010-12-01

The regulation of gene expression involves a multifarious regulatory system. Each gene contains a unique combination of cis-acting regulatory sequence elements in the 5' regulatory region that determines its temporal and spatial expression. Cis-acting regulatory elements are essential transcriptional gene regulatory units; they control many biological processes and stress responses. Thus a full understanding of the transcriptional gene regulation system will depend on successful functional analyses of cis-acting elements. Cis-acting regulatory elements present within the 5' regulatory region of the sucrose transporter gene families in rice (Oryza sativa Japonica cultivar-group) and Arabidopsis thaliana, were identified using a bioinformatics approach. The possible cis-acting regulatory elements were predicted by scanning 1.5kbp of 5' regulatory regions of the sucrose transporter genes translational start sites, using Plant CARE, PLACE and Genomatix Matinspector professional databases. Several cis-acting regulatory elements that are associated with plant development, plant hormonal regulation and stress response were identified, and were present in varying frequencies within the 1.5kbp of 5' regulatory region, among which are; A-box, RY, CAT, Pyrimidine-box, Sucrose-box, ABRE, ARF, ERE, GARE, Me-JA, ARE, DRE, GA-motif, GATA, GT-1, MYC, MYB, W-box, and I-box. This result reveals the probable cis-acting regulatory elements that possibly are involved in the expression and regulation of sucrose transporter gene families in rice and Arabidopsis thaliana during cellular development or environmental stress conditions.

Colloid-facilitated radionuclide transport: a regulatory perspective

Science.gov (United States)

Dam, W. L.; Pickett, D. A.; Codell, R. B.; Nicholson, T. J.

2001-12-01

What hydrogeologic-geochemical-microbial conditions and processes affect migration of radionuclides sorbed onto microparticles or native colloid-sized radionuclide particles? The U.S. Nuclear Regulatory Commission (NRC) is responsible for protecting public health, safety, and the environment at numerous nuclear facilities including a potential high-level nuclear waste disposal site. To fulfill these obligations, NRC needs to understand the mechanisms controlling radionuclide release and transport and their importance to performance. The current focus of NRC staff reviews and technical interactions dealing with colloid-facilitated transport relates to the potential nuclear-waste repository at Yucca Mountain, Nevada. NRC staff performed bounding calculations to quantify radionuclide releases available for ground-water transport to potential receptors from a Yucca Mountain repository. Preliminary analyses suggest insignificant doses of plutonium and americium colloids could be derived from spent nuclear fuel. Using surface complexation models, NRC staff found that colloids can potentially lower actinide retardation factors by up to several orders of magnitude. Performance assessment calculations, in which colloidal transport of plutonium and americium was simulated by assuming no sorption or matrix diffusion, indicated no effect of colloids on human dose within the 10,000 year compliance period due largely to long waste-package lifetimes. NRC staff have identified information gaps and developed technical agreements with the U.S. Department of Energy (DOE) to ensure sufficient information will be presented in any potential future Yucca Mountain license application. DOE has agreed to identify which radionuclides could be transported via colloids, incorporate uncertainties in colloid formation, release and transport parameters, and conceptual models, and address the applicability of field data using synthetic microspheres as colloid analogs. NRC is currently

OAK B202 THE LARGE ASPECT RATIO LIMIT OF NEOCLASSICAL TRANSPORT THEORY. This article presents a comprehensive description of neoclassical transport theory in the banana regime for large aspect ratio flux surfaces of arbitrary shapes. The method of matched asymptotic expansions is used to obtain analytical solutions for plasma distribution functions and to compute transport coefficients. The method provides justification for retaining only the part of the Fokker-Planck operator that involves the second derivative with respect to the cosine of the pitch angle for the trapped and barely circulating particles. It leads to a simple equation for the freely circulating particles with boundary conditions that embody a discontinuity separating particles moving in opposite directions. Corrections to the transport coefficients are obtained by generalizing an existing boundary layer analysis. The system of moment and field equations is consistently taken in the cylinder limit, which facilitates discussion of the treatment of dynamical constraints. it is shown that the nonlocal nature of Ohm's law in neoclassical theory renders the mathematical problem of plasma transport with changing flux surfaces nonstandard.

Regulatory aspects of radiopharmaceuticals

International Nuclear Information System (INIS)

Kristensen, K.

1985-01-01

Regulatory systems in the field of radiopharmaceuticals have two main purposes: efficacy and safety. Efficacy expresses the quality of the diagnostic and therapeutic process for the patient. Safety involves the patient, the staff, and the environment. The world situation regarding regulations for radiopharmaceuticals is reviewed on the basis of a survey in WHO Member States. The main content of such regulations is discussed. The special properties of radiopharmaceuticals compared with ordinary drugs may call for modified regulations. Several countries are preparing such regulations. Close co-operation and good understanding among scientists working in hospital research, industry and regulatory bodies will be of great importance for the fast and safe introduction of new radiopharmaceuticals for the benefit of the patient. Before introducing new legislation in this field, a radiopharmaceutical expert should analyse the situation in the country and the relationship to the existing regulations. It is expected that the most important factor in promoting the fast introduction of new, safe and effective radiopharmaceuticals will be the training of people working within the regulatory bodies. It is foreseen that the IAEA and WHO will have an important role to play by providing expert advice and training in this area. (author)

The public information aspects of the regulation of nuclear power present a unique set of problems. Not only must the regulators communicate often complex technical information to the public, they must also assure the public, the press and the legislative bodies of the adequacy of the regulatory process and the safety of power plant operations. The United States Nuclear Regulatory Commission (NRC), recognizing the importance of a continuing, open dialogue with the public, has placed particular emphasis on informing the public of its operations. NRC's experiences have been both good and bad. On balance, however, the NRC believes it is following the best course by conducting its operations openly and candidly. (author)

2014-01-01

The implementation of a deep geological spent fuel disposal concept in Sweden poses challenges on both implementer and regulator in many aspects. One such challenge is the application of the regulatory framework in a different situation compared to conventional process type nuclear facilities. A specific challenge in this regard is how to understand and address constraints from post-closure safety related to the construction and operation of the repository. The maybe most challenging aspect, however, is the unusually long time frame, i.e. many generations, for realization of the project. This paper addresses some of these challenges from a regulatory perspective. (authors)

The regulatory mission with respect to radioactive waste disposal in Switzerland consists of the following tasks: to assess proposed solutions and supervise the preparation for geological disposal of radioactive waste, to review the licence applications in accord with the stepwise implementation process; to supervise the transport of radioactive material to and from nuclear installations; to supervise surface facilities and underground installations of deep geological repositories; and to supervise the safety of staff and the public and their protection from radiation. Related nuclear legislation consists of the Nuclear Energy Act, the Radiological Protection Act including the corresponding Ordinances, and the Ordinance on the Decommissioning Fund and the Waste Disposal Fund for Nuclear Installations. Design, construction and operating principles for DGRs and requirements for the safety case have been developed recently by the Swiss regulatory body. The corresponding guideline specifies protection objectives, protection criteria and specific requirements for DGRs, defines the procedure to be followed for demonstrating the safety of a geological repository, and identifies requirements for the operation of facilities and for their closure. The Nuclear Energy Act stipulates a series of licences that must be obtained prior to completion of a DGR - starting with a general licence, followed by the licences for construction and operation, and finally the closure order

The aspects of plant ageing management (AM) gained increasing attention over the last ten years. Numerous technical studies have been performed to study the impact of ageing mechanisms on the safe and reliable operation of nuclear power plants. National research activities have been initiated or are in progress to provide the technical basis for decision making processes. The long-term operation of nuclear power plants is influenced by economic considerations, the socio-economic environment including public acceptance, developments in research and the regulatory framework, the availability of technical infrastructure to maintain and service the systems, structures and components as well as qualified personnel. Besides national activities there are a number of international activities in particular under the umbrella of the IAEA, the OECD and the EU. The paper will provide the summary on Nuclear Plant Life Management (PLIM) (or Ageing Management Program (AMP)) and Plant Life Extension (PLEX) development in USA and European countries. Also, insights from such effort currently performing in Slovenia will be discussed.(author)

Design aspects of plutonium air-transportable packages

International Nuclear Information System (INIS)

Allen, G.C.; Moya, J.L.; Pierce, J.D.; Attaway, S.W.

1989-01-01

Recent worldwide interest in transporting plutonium powders by air has created a need for expanding the packaging technology base as well as improving their understanding of how plutonium air transport (PAT) packagings perform during severe accident tests. Historically it has not been possible to establish design rules for individual package components because of the complex way parts interacted in forming a successful whole unit. Also, computer analyses were only considered valid for very limited portions of the design effort because of large deformations, localized tearing occurring in the package during accident testing, and extensive use of orthotropic materials. Consequently, iterative design and experimentation has historically been used to develop plutonium air-transportable packages. Full-scale prototypes have been tested since scaling of packages utilizing wood as an energy absorber and thermal insulator has not proven to be very successful. This is because the wood grain and dynamic performance of the wood during crush do not always scale. The high cost of full-scale testing of large packages has certainly hindered obtaining additional data and development new designs. The testing criteria for PAT packages, as described in the US Nuclear Regulatory Commission's Qualification Criteria to Certify a Package for Air Transport of Plutonium, NUREG-0360, 1978, are summarized. Computer modeling techniques have greatly improved over the last ten years, and there are some areas of opportunity for future applications to plutonium air-transportable package design problems. Having developed a better understanding of the performance of current packages, they have the opportunity to make major improvements in new packaging concepts. Each of these areas is explored in further depth to establish their impact on design practices for air-transportable packages

Regulatory status of burnup credit for storage and transport of spent fuel in Germany

Neuber, J.C.; Schweer, H.H.; Johann, H.G.

2001-01-01

This paper describes the regulatory status of burnup credit applications to pond storage and dry-cask transport and storage of spent fuel in Germany. Burnup credit for wet storage of LWR fuel at nuclear power plants has to comply with the newly developed safety standard DIN 25471. This standard establishes the safety requirements for burnup credit criticality safety analysis of LWR fuel storage ponds and gives guidance on meeting these requirements. Licensing evaluations of dry transport systems are based on the application of the IAEA Safety Standards Series No.ST-1. However, because of the fact that burnup credit for dry-cask transport becomes more and more inevitable due to increasing initial enrichment of the fuel, and because of the increasing importance of dry-cask storage in Germany, the necessity of giving regulatory guidance on applying burnup credit to dry-cask transport and storage is seen.

1997-09-01

In this report, the Advisory Committee on Nuclear Safety (ACNS) presents the results of its study on how the system of the transport of radioactive material (TRM) in Canada is regulated, how it operates, and how it performs. The report deals with the transport of packages, including Type B packages which are used to carry large quantities of radioactive material, but not with the transport of spent nuclear fuel or with the transport of low-level historical waste. The ACNS has examined the Canadian experience in the TRM area, the regulatory framework in Canada with respect to the TRM some relevant aspects of training workers and monitoring compliance with regulatory requirements, the state of the emergency preparedness of organizations involved in the TRM and the process of updating present regulations by the Atomic Energy Control Board (AECB). As a result of this study, the ACNS concludes that the current Canadian regulatory system in the TRM is sound and that the TRM is, for the most part, conducted safely. However, improvements can be made in a number of areas, such as: determining the exposures of workers who transport radioactive material; rewording the proposed Transport Regulations in plain language; training all appropriate personnel regarding the AECB and Transport Canada (TC) Regulations; enforcing compliance with the regulations; and increasing the level of cooperation between the federal agencies and provincial authorities involved in the inspection and emergency preparedness aspects of the TRM. It is also noted that Bill C-23, the Nuclear Safety and Control Act, imposes a new requirement, subject to the Regulations, for a licence for a carrier to transport some types of radioactive material

Devillers, C.; Grenier, M.; Lombard, J.; Mathieu, F.

1993-01-01

The introduction of the 10 mSv.h -1 at 3 m limit for LSA unshielded material makes it impossible to transport, as LSA material, the highest radiation level wastes from EdF PWR's operations. At present, the EdF's waste blocks can be transported as LSA III material by special arrangement. A new package design, equivalent to a Type B package, will be available for their transport before the end of the year 1995. It consists of a re-usable steel cylinder over-packing each block. Compliance of this package model with transport safety requirements will be demonstrated by taking into account the non-dispersability, as LSA III material, of the irradiating waste. A two-step approach has been accepted by the French Competent Authority for the transport of these wastes: (1) a specific ISO 20 container, thermally insulated, can be used by special arrangement for the transport of LSA combustible material having a total activity per conveyance higher than 100 A2. Furthermore, additional safety measures have to be implemented for these consignments. (2) After the end of 1995, a Type B package must be used for activity contents per conveyance higher than 100 A2. A specific 20' ISO container, complying with Type B requirements, is being developed for that purpose. (author)

With the creation of Australian Radiation Protection and Nuclear Safety Agency (ARPANSA) the Australian approach to criticality safety was revisited. Consistency with international best practices is required by the Act that created ARPANSA and this was applied to practices in criticality safety adopted in other countries. This required extensive regulatory efforts both in auditing the major Australian Nuclear Operator, Australian Nuclear Science and Technology Organisation (ANSTO), and assessing the existing in Australia criticality safety practices and implementing the required changes using the new legislative power of ARPANSA. The adopted regulatory approach is formulated through both the issued by ARPANSA licenses for nuclear installations (including reactors, fuel stores and radioactive waste stores) and the string of new regulatory documents, including the Regulatory Assessment Principles and the Regulatory Assessment Guidelines for criticality safety. The main features of the adopted regulation include the requirements of independent peer-review, ongoing refresher training coupled with annual accreditation and the reliance on the safe design rather than on an administrative control.

Large-aspect-ratio limit of neoclassical transport theory

International Nuclear Information System (INIS)

Wong, S K.; Chan, V.S.

2003-01-01

This paper presents a comprehensive description of neoclassical transport theory in the banana regime for large-aspect-ratio flux surfaces of arbitrary shapes. The method of matched-asymptotic expansions is used to obtain analytical solutions for plasma distribution functions and to compute transport coefficients. The method provides justification for retaining only the part of the Fokker-Planck operator that involves the second derivative with respect to the cosine of the pitch angle for the trapped and barely circulating particles. It leads to a simple equation for the freely circulating particles with boundary conditions that embody a discontinuity separating particles moving in opposite directions. Corrections to the transport coefficients are obtained by generalizing an existing boundary layer analysis. The system of moment and field equations is consistently taken in the cylinder limit, which facilitates the discussion of the treatment of dynamical constraints. It is shown that the nonlocal nature of Ohm's law in neoclassical theory renders the mathematical problem of plasma transport with changing flux surfaces nonstandard

Chu, C.

2016-01-01

Since 1980s, the IAEA Regulation for safe transport of radioactive material was introduced into China; the regulatory system of China began with international standards, and walked towards the institutionalized. In 2003 the National People’s Congress (NPC) promulgated “the Act on the Prevention of Radioactive Pollution of the People's Republic of China”. In 2009 “Regulation for the Safe Transport of Radioactive Material” (Referred to “Regulation”) was promulgated by the State Council. Subsequently, the National Nuclear Safety Administration (NNSA) began to formulate executive detailed department rules, regulations guidelines and standards. The present system of acts, regulations and standards on management of safe transport of radioactive material in China and future planning were introduced in this paper. Meanwhile, the paper described the specific administration requirements of the Regulation on classification management of radioactive materials, license management of transport packaging including design, manufacture and use, licensing management of transport activities and the provisions of illegal behaviors arising in safe transport of radioactive material.

Mixed waste is waste that satisfies the definition of low-level radioactive waste in the Low-Level Radioactive Waste Policy Amendments Act of 1985 (LLRWPAA) and contains hazardous waste that is either: (1) listed as a hazardous waste in 40 CFR 261, Subpart D; or (2) causes the waste to exhibit any of the characteristics identified in 40 CFR 261, Subpart C. Low-level radioactive waste is defined in the LLRWPAA as radioactive material that is not high level waste, spent nuclear fuel, or byproduct material, as defined in Section 11e(2) of the Atomic Energy Act of 1954, and is classified as low-level waste by the U.S. Nuclear Regulatory Commission (NRC). This paper discusses dual regulatory (NRC and Environmental Protection Agency) responsibility, overview of joint NRC/EPA guidance, workshops, national mixed waste survey, and principal mixed waste uncertainties

Magnetics transport aspects of EBTR reactors

International Nuclear Information System (INIS)

Bathke, C.G.

1981-01-01

The magnetic model developed for the ELMO Bumpy Torus Reactor (EBTR) study is described. A multiple-loop current simulation of toroidal-field (TF) and aspect-ratio-enhancement (ARE) coils is used to calculate the vacuum magnetic field. The bounce-averaged vertical drift velocity, v/sub y/, and poloidal drift frequency, Ω, are determined from the field topology. Upon performing the appropriate averages of v/sub y/ and Ω, the point-plasma toroidal curvature, R/sub T/, and magnetic curvature, R/sub c/, are obtained for use in modeling EBT transport. In addition, the fraction, f/sub α/, of alpha particles completing their first orbit within the plasma is calculated

Evaluation of transport safety analysis processes of radioactive material performed by a regulatory body

International Nuclear Information System (INIS)

Mattar, Patricia Morais

2017-01-01

Radioactive substances have many beneficial applications, ranging from power generation to uses in medicine, industry and agriculture. As a rule, they are produced in different places from where they are used, needing to be transported. In order for transport to take place safely and efficiently, national and international standards must be complied with. This research aims to assess the safety analysis processes for the transport of radioactive material carried out by the regulatory body in Brazil, from the point of view of their compliance with the International Atomic Energy Agency (IAEA) standards. The self-assessment methodology named SARIS, developed by the AIEA, was used. The following steps were carried out: evaluation of the Diagnosis and Processes Mapping; responses to the SARIS Question Set and complementary questions; SWOT analysis; interviews with stakeholders and evaluation of a TranSAS mission conducted by the IAEA in 2002. Considering only SARIS questions, processes are 100% adherent. The deepening of the research, however, led to the development of twenty-two improvement proposals and the identification of nine good practices. The results showed that the safety analysis processes of the transport of radioactive material are being carried out in a structured, safe and reliable way but also that there is much opportunity for improvement. The formulation of an action plan, based on the presented proposals, can bring to the regulatory body many benefits. This would be an important step towards convening an external evaluation, providing greater reliability and transparency to the regulatory body´s processes. (author)

The kinetic mechanism of the transport catalyzed by the human glutamine/neutral amino acid transporter hASCT2 over-expressed in P. pastoris was determined in proteoliposomes by pseudo-bi-substrate kinetic analysis of the Na(+)-glutamineex/glutaminein transport reaction. A random simultaneous mechanism resulted from the experimental analysis. Purified functional hASCT2 was chemically cross-linked to a stable dimeric form. The oligomeric structure correlated well with the kinetic mechanism of transport. Half-saturation constants (Km) of the transporter for the other substrates Ala, Ser, Asn and Thr were measured both on the external and internal side. External Km were much lower than the internal ones confirming the asymmetry of the transporter. The electric nature of the transport reaction was determined imposing a negative inside membrane potential generated by K(+) gradients in the presence of valinomycin. The transport reaction resulted to be electrogenic and the electrogenicity originated from external Na(+). Internal Na(+) exerted a stimulatory effect on the transport activity which could be explained by a regulatory, not a counter-transport, effect. Native and deglycosylated hASCT2 extracted from HeLa showed the same transport features demonstrating that the glycosyl moiety has no role in transport function. Both in vitro and in vivo interactions of hASCT2 with the scaffold protein PDZK1 were revealed.

Situation on regulatory aspects of underground disposal of radioactivity wastes in Japan

International Nuclear Information System (INIS)

Murano, T.; Asano, T.; Matsubara, N.

1978-01-01

At present, in Japan, there exists no law specifically regulating the underground disposal of radioactive wastes although various regulations deal with disposal safety measures in a general way. For the moment, apart from the need to gain public acceptance of such disposal, the problem is essentially one of technical feasibility, and a geological study is currently being undertaken by the Science and Technology Agency. This same Agency is also looking at the problem of a long-term waste management system, but it is the Nuclear Safety Commission, created in 1978, which will be primarily responsible for all regulatory aspects of safety.

Collisional Transport in a Low Aspect Ratio Tokamak -- Beyond the Drift Kinetic Formalism

International Nuclear Information System (INIS)

Gates, D.A.; White, R.B.

2004-01-01

Calculations of collisional thermal and particle diffusivities in toroidal magnetic plasma confinement devices order the toroidal gyroradius to be small relative to the poloidal gyroradius. This ordering is central to what is usually referred to as neoclassical transport theory. This ordering is incorrect at low aspect ratio, where it can often be the case that the toroidal gyroradius is larger than the poloidal gyroradius. We calculate the correction to the particle and thermal diffusivities at low aspect ratio by comparing the diffusivities as determined by a full orbit code (which we refer to as omni-classical diffusion) with those from a gyroaveraged orbit code (neoclassical diffusion). In typical low aspect ratio devices the omni-classical diffusion can be up to 2.5 times the calculated neoclassical value. We discuss the implications of this work on the analysis of collisional transport in low aspect ratio magnetic confinement experiments

In beginning, a history of legislative process regulating industrial utilisation of nuclear energy is given, including detailed list of decrees issued by the first regulatory body supervising Czech nuclear installations - Czechoslovak Atomic Energy Commission (CSKAE). Current status of nuclear regulations and radiation protection, especially in connection with Atomic Act (Act No 18/1997 Coll.), is described. The Atomic Act transfers into the Czech legal system a number of obligations following from the Vienna Convention on Civil Liability for Nuclear Damage and Joint Protocol relating to the Application of the Vienna and Paris Convention, to which the Czech Republic had acceded. Actual duties and competence of current nuclear regulatory body - State Office for Nuclear Safety (SUJB) - are given in detail. Execution of the State supervision of peaceful utilisation of nuclear energy and ionising radiation is laid out in several articles of the Act, which comprises: control activities of the SUJB, remedial measures, penalties. Material and human resources are sufficient for fulfilment of the basic functions for which SUJB is authorised by the law. For 1998, the SUJB allotted staff of 149, approximately 2/3 of that number are nuclear safety and radiation protection inspectors. The SUJB budget for 1998 is approximately 180 million Czech crowns (roughly 6 million US dollars). Inspection activity of SUJB is carried out in three different ways: routine inspections, planned specialised inspections, inspections as a response to a certain situation (ad-hoc inspections). Approach to the licensing of major plant upgrades and backfittings are mainly illustrated on the Temelin NPP licensing. Regulatory position and practices concerning review activities are presented.

Regulatory requirements for the transport of radioactive materials in Canada

Energy Technology Data Exchange (ETDEWEB)

Garg, R. [Canadian Nuclear Safety Commission, Ottawa (Canada)

2004-07-01

Canada is a major producer and shipper of radioactive material. Each year more than a million packages are transported in Canada. The safety record with the transport of RAM in Canada has historically been excellent. There have never been any serious injuries, overexposure or fatality or environmental consequences attributable to the radioactive nature of such material being transported or being involved in a transport accident. In Canada, the Canadian Nuclear Safety Commission (CNSC) is the prime agency of the federal government entrusted with regulating all activities related to the use of nuclear energy and nuclear substances including the packaging and transport of nuclear substances. The mission of the CNSC is to regulate the use of nuclear energy and materials to protect health, safety, security of the person and the environment and to respect Canada's international commitments on the peaceful use of nuclear energy. The division of responsibility for the regulation of transport of radioactive material has been split between Transport Canada and the CNSC. The governing Transport Canada's regulations are Transport of Dangerous Goods (TDG) Regulations and the CNSC regulations are Packaging and Transport of Nuclear Substances Regulations (PTNSR). Canada has actively participated in the development of the IAEA regulations for the safe transport of radioactive material since 1960. As an IAEA member state, Canada generally follows the requirements of IAEA regulations with few deviations. The Nuclear Safety and Control Act (NSCA) strongly supports Canada's international obligations to ensure safe packaging, transport, storage and disposal of nuclear substances, prescribed equipment and prescribed information. Prescribed equipment and prescribed information are defined in the CNSC General Nuclear Safety and Control Regulations.

2004-01-01

This paper presents some regulatory practices and experiences of the Philippine Nuclear Research Institute (PNRI) in ensuring safe transport of radioactive materials. The regulation and licensing the use of radioactive materials started in 1958. The number of packages containing radioactive materials transported into and within the country has increased with the increase number of licensees. During the period 2000-2002, the total number of licensees is 293, 311 and 311 respectively. The PNRI issues certificates of release and certificate of transport/authority to transport. Based on the data of certificates, the topmost sealed source shipments from abroad, mostly in type A package, are 192 Ir and 125 I for brachytherapy. For unsealed sources, also mostly in type A package, the topmost radioactive materials are 99m Tc (generators), 131 I, 201 Tl mainly for medical diagnosis. From the data on certificates of transport, the total number of packages inspected for the period 2000-2002 is 464, 577 and 747 respectively. The experiences in the enforcement of the transport regulations and the implication of issuing certificates of release and transport are discussed and recommendations are presented. (Authors)

Transportation of radioactive materials: legislative and regulatory information system

Fore, C.S.; Heiskell, M.M.

1980-01-01

The transportation of radioactive materials, as well as hazardous materials in general, has been an issue of ever-increasing concern and an object of numerous regulations and legislative actions worldwide. The Transportation Technology Center of the US Department of Energy's Sandia Laboratories in Albuquerque, New Mexico, is currently involved in developing a national program to assure the safe shipment of radioactive materials. At Oak Ridge National Laboratory (ORNL), Oak Ridge, Tennessee, this overall effort is being supported in a specialized manner. As part of the Logistics Modeling program at ORNL, the Ecological Sciences Information Center has developed comprehensive data bases containing legislative and regulatory actions relevant to the transportation of hazardous materials. The data bases are separated according to status level of the legislation. The Current Legislation Data Base includes all new legislative actions introduced during the present year (1980) or those bills carried over from the previous year's sessions. The second data file, Historical Legislation Data Base, consists of all legislative actions since 1976 that have passed and become public laws, as well as those actions that were unsuccessful and were classified as denied by law. Currently the data bases include state-, local-, and federal, level legislation, with emphasis on the transportation of radioactive materials. Because of their relevance to the transportation issues, actions involving related subject areas such as, disposal and storage of radioactive wastes, moratoriums on power plant construction, and remedial actions studies, special agencies to regulate shipment of radioactive materials, and requirements of advanced notification, permits and escorts are also included in the data bases

Regulatory aspects of management of change - Summary and conclusions

International Nuclear Information System (INIS)

2002-01-01

Nuclear licensees are increasingly required to adapt to a more challenging commercial environment as moves to de-regulate electricity markets gather pace. One of the costs that is often perceived as being amenable to control is staffing, and hence there is significant exploration of new strategies for managing staffing levels. This report presents the outputs from a Workshop convened by the Special Experts' Group in Human and Organisational Factors (SEGHOF) of the Committee for the Safety of Nuclear Installations (CSNI) and organised by the UK Nuclear Installations Inspectorate (NII). The purpose of the workshop was to facilitate the exchange of views on, and approaches towards, the regulation of organisational change. The major risks associated with organisational change were discussed, and a range of regulatory challenges was identified for detailed discussion. There was agreement that the licensee must retain the responsibility to manage its own business but that organisational issues should be subject to regulatory scrutiny if they have the potential to impact on safety. The regulator should be able to demonstrate an approach to oversight of organisational change which is valid, transparent and consistent, and should inform the licensee of its expectations in terms of information supplied, communication and timing. The workshop confirmed that there is significant agreement between regulators concerning the need for licensees to put in place arrangements to manage organisational change. There was also broad consensus on what should constitute the elements of a licensee's management of change process. Differing views were evident about the balance between regulatory scrutiny of the process, as opposed to the outcomes of change, which largely represents differing regulatory regimes and philosophies. However, it was acknowledged that the regulator must be capable of taking an early view of the adequacy of proposed changes, rather than monitoring outcomes alone

1992-01-01

The regulation of radioactive material transport has a long and successful history. Prior to 1966, these activities were regulated by the Interstate Commerce Commission (ICC) Bureau of Explosives (the ICC was predecessor to the Department of Transportation (DOT)). In 1966, the Atomic Energy Commission (AEC) developed what is now 10 CFR 71, concurrently with the development of similar international standards. In 1975, the AEC was reorganized and the Nuclear Regulatory Commission (NRC) was established as an independent regulatory commission. The NRC was given responsibility for the regulation of commercial use of radioactive materials, including transportation. This paper discusses various aspects of the NRC's role in the transport of radioactive material as well as its role in the design and certification of casks necessary to the transport of this material

The U.S. Department of Transportation is responsible for implementing new safety improvements and regulations with the goal of ensuring limited funds are distributed to where they can have the greatest impact on safety. In this work, we conduct a study of new regulations and other reactions (such as recalls) to fatal accidents in several different modes of transportation implemented from 2002 to 2009. We find that in the safest modes of commercial aviation and bus transport, the amount of spending on new regulations is high in relation to the number of fatalities compared to the regulatory attention received by less safe modes of general aviation and private automobiles. Additionally, we study two major fatal accident investigations from commercial aviation and two major automotive recalls associated with fatal accidents. We find differences in the cost per expected fatality prevented for these reactions, with the airline accident investigations being more cost effective. Overall, we observe trends in both the automotive and aviation sectors that suggest that public transportation receives more regulatory attention than private transport. We also observe that the types of safety remedies utilized, regulation versus investigation, have varying levels of effectiveness in different transport modes. We suggest that these differences are indicative of increased public demand for safety in modes where a third party may be held responsible, even for those not participating in the transportation. These findings have important implications for the transportation industry, policymakers, and for estimating the public demand for safety in new transport modes. © 2017 Society for Risk Analysis.

Meeting report of the "Second Symposium on Pharmacology of Cytochrome P450 and Transporters" organized by the Cuban Society of Pharmacology in collaboration with the European Society of Pharmacogenetics and Theranostics (ESPT) and the Ibero-American Network of Pharmacogenetics and Pharmacogenomics (www.ribef.com). The Symposium covered different topics on pharmacogenetics and its clinical implications, focusing on Latin-American populations. The activities of the ESPT were also presented and discussed. The topics addressed were regulatory aspects, the use of pharmacogenetics in pre-clinical research, herbal medicine, and natural products, ending with a discussion about translation into clinical practice, specifically for cardiovascular disorders and psychiatry. Finally, the implication for population diversity in Latin America was also discussed. The RIBEF initiative represents a promising step towards the inclusion of Latin American populations among those to benefit from the implementation of pharmacogenetics in clinical practice. Among current RIBEF activities, the CEIBA.FP Consortium aims to study the variability of pheno- and genotypes in Hispanics that are relevant to pharmacogenetics. For this purpose, populations from Mexico, Cuba, Nicaragua, Costa Rica, Ecuador, Colombia, Brasil, Perú, Chile, Uruguay, Argentina, Portugal, and Spain are currently being studied. The meeting's main conclusion was that population pharmacogenetic studies as well as academic clinical trials might need to be conducted in the different geographic locations/countries. This is important in order to improve drug safety, dosage recommendations, and pharmacovigilance programs, because environmental and ethnic factors vary across locations.

Local transport of 18F FDG: guidelines and practical aspects

International Nuclear Information System (INIS)

Sharma, Neeraj

2010-01-01

Full text: Transport of radioactive material in India is governed by Atomic Energy Regulatory Board (AERB) safety code AERB/SC/TR-1 which is based on the International Atomic Energy Agency (IAEA) regulations for the safe transport of radioactive material. The basic requirement for the transport of radioactive material is that the package containing the material shall be designed and prepared in such a way that during the whole process of transport, the radioactive material remains contained to prevent contamination and remains shielded to avoid unacceptable radiation exposure to cargo handlers and public. The types of packages used for the transport of radioactive materials are Excepted, Industrial, Type A, Type B(U) and Type B(M) packages. Type A packages are used for the transport of dispersible radioactive material of moderate activity such as nuclear medicine sources used for diagnostic and therapeutic purposes. Transport of 18 F FDG comes under this category. The use of PET-CT in India has grown rapidly over the last few years. Currently, in India, there are around 60 PET-CTs and 15 cyclotrons. Most of these PET-CT facilities are supplied with FDG from off-site cyclotrons. The prime responsibility for ensuring safe transport of 18 F FDG lies with the consignor. The consignor needs to ensure that the appropriate packaging is selected for the transport of 18 F FDG and the package is prepared, marked and labeled as per the regulations. A material such as Tungsten or lead of appropriate thickness and design is used in packaging. Once the package is prepared as per the prescribed procedures, it can be transported by any mode of transport i.e. by road, rail, sea or air. Transport documents are very important during transport; they include (1) declaration by the consignor, (2) instructions to the carrier, (3) a Transport Emergency Card (TREMCARD) and (4) Instructions in writing to the carrier for emergency measures. In addition to this, one working radiation survey

Regulatory aspects for nuclear and radiation applications

The Atomic Energy Regulatory Board (AERB) is the national authority for ensuring that the use of ionizing radiation and nuclear energy does not cause any undue risk to the health of workers, members of the public and to the environment. AERB was constituted on November 15, 1983 and derives its regulatory power from the rules and notifications promulgated under the Atomic Energy Act, 1962 and the Environment (Protection) Act, 1986. AERB is provided with the necessary powers and mandate to frame safety policies, lay down safety standards and requirements for monitoring and enforcing the safety provisions. AERB follows multi-tier system for its review and assessment, safety monitoring, surveillance and enforcement. While regulating various nuclear and radiation facilities, AERB adopts a graded approach taking into account the hazard potential associated with the facilities being regulated. The regulatory process has been continuous evolving to cater to the new developments in reactor and radiation technologies. The regulatory effectiveness and efficiency of AERB have grown over the last three decades to make it into a robust organization. The radiation protection infrastructure in the country is on a sound footing and is constantly being strengthened based on experience and continued research and development. As one of its mandates AERB prescribes radiation dose limits for the occupational workers and the public, in line with the IAEA Safety Standard and ICRP recommendations. The current dose limits and the radiation safety requirements are more stringent than past. To meet the current safety standards, it is important for the facilities to have state of art radiation monitoring system and programme in place. While recognizing the current system in place, this presentation also highlights certain key radiation protection challenges associated with the implementation of radiation protection standards in the nuclear and radiation facilities especially in the areas of

Role of bundle helices in a regulatory crosstalk in the trimeric betaine transporter BetP.

Science.gov (United States)

Gärtner, Rebecca M; Perez, Camilo; Koshy, Caroline; Ziegler, Christine

2011-12-02

The Na(+)-coupled betaine symporter BetP regulates transport activity in response to hyperosmotic stress only in its trimeric state, suggesting a regulatory crosstalk between individual protomers. BetP shares the overall fold of two inverted structurally related five-transmembrane (TM) helix repeats with the sequence-unrelated Na(+)-coupled symporters LeuT, vSGLT, and Mhp1, which are neither trimeric nor regulated in transport activity. Conformational changes characteristic for this transporter fold involve the two first helices of each repeat, which form a four-TM-helix bundle. Here, we identify two ionic networks in BetP located on both sides of the membrane that might be responsible for BetP's unique regulatory behavior by restricting the conformational flexibility of the four-TM-helix bundle. The cytoplasmic ionic interaction network links both first helices of each repeat in one protomer to the osmosensing C-terminal domain of the adjacent protomer. Moreover, the periplasmic ionic interaction network conformationally locks the four-TM-helix bundle between the same neighbor protomers. By a combination of site-directed mutagenesis, cross-linking, and betaine uptake measurements, we demonstrate how conformational changes in individual bundle helices are transduced to the entire bundle by specific inter-helical interactions. We suggest that one purpose of bundle networking is to assist crosstalk between protomers during transport regulation by specifically modulating the transition from outward-facing to inward-facing state.

Shirley, C.G.; Wilmot, E.L.; Shepherd, E.W.

1981-09-01

The 96th Congress of the United States, as part of the Low-level Radioactive Waste Policy Act of 1980 (Public Law 96-573), instructed the Secretary of the Department of Energy (DOE) to prepare a report on the current US low-level waste management situation and the conditions and requirements for management on a regional basis. The Transportation Technology Center has compared the transportation requirement and regional management scenarios for commercial low-level radioactive waste in support of the DOE response to this instruction. Using 1979 low-level waste volumes shipped to commercial burial grounds and six management regions postulated by DOE, transportation requirements were estimated and compared for the two management scenarios in terms of cumulative shipping distance and transportation cost. Effects of these results on the demand for transportation services and equipment and on population risks were considered. Finally, current regulatory issues and the potential effects of regional management on regulation of low-level waste transportation were reviewed

Regulatory aspects of fusion power-lessons from fission plants

International Nuclear Information System (INIS)

Natalizio, A.; Brunnader, H.; Sood, S.K.

1993-01-01

Experience from fission reactors has shown the regulatory process for licensing a nuclear facility to be legalistic, lengthy, unpredictable, and costly. This experience also indicates that much of the regulatory debate is focused on safety margins, that is, the smaller the safety margins the bigger the regulatory debate and the greater the amount of proof required to satisfy the regulatory. Such experience suggests that caution and prudence guide the development of a regulatory regime for fusion reactors. Fusion has intrinsic safety and environmental advantages over fission, which should alleviate significantly, or even eliminate, the regulatory problems associated with fission. The absence of a criticality concern and the absence of fission products preclude a Chernobyl type accident from occurring in a fusion reactor. Although in a fusion reactor there are large inventories of radioactive products that can be mobilized, the total quantity is orders of magnitude smaller than in fission power reactors. The bulk of the radioactivity in a fusion reactor is either activation products in steel structures, or tritium fuel supplies safely stored in the form of a metal tritide in storage beds. The quantity of tritium that can be mobilized under accident conditions is much less than ten million curies. This compares very favorably with a fission product inventory greater than ten billion curies in a fission power reactor. Furthermore, in a fission reactor, all of the reactivity is contained in a steel vessel that is pressurized to about 150 atmospheres, whereas in a fusion reactor, the inventory of radioactive material is dispersed in different areas of the plant, such that it is improbable that a single event could give rise to the release of the entire inventory to the environment. With such significant intrinsic safety advantages there is no a priori need to make fusion requirements/regulations more demanding and more stringent than fission

Transport of 1,8% U235 enriched fuel rods needs both the evaluation of the radiological risk and considerations about criticality aspects. Issues as diverse production characteristics, storage facilities in the source of origin an economical aspects have to be added to the radiological and nuclear considerations. Transport of those rods through national territory must comply with the Argentine Regulatory authority's regulations, based on the Safety Series No. 6, (ed. 1985) -as amended 1990- IAEA. Safety criteria are exposed, taking into account the amount of material to be transported, container characteristics, packaging type and expedition conditions. (author)

Transport ac losses in technical superconductors based on Bi-2223 tape material are influenced by many parameters. The major factors that define the ac performance of such conductors are the following: the size and number of filaments, their geometrical arrangement in the cross-section of the conductor, the twist pitch length, the resistivity of the matrix, the presence of oxide barriers around the filaments and deformation procedures such as sequential pressing or rolling followed by appropriate thermal treatment. In the present paper the above aspects are addressed from the viewpoint of the materials science of technical conductor design. Transport ac losses at power frequencies in different types of Bi-2223 conductor are presented and analysed. The results of conductor design analysis with respect to the coexistence of the superconductor with other materials in the conductor structure are presented. New concepts for minimization of the transport ac losses are discussed in detail. (author)

2004-01-01

Changes in the regulatory framework governing the Radiation Processing Industry have the potential to make a real business impact on day-to-day profitability. Many areas of the Radiation Processing Industry are affected by changes in the regulatory framework within which these areas are managed. When planning for such changes the transportation element in the shipment of sealed cobalt radiation sources is an area that is often neglected by some parts of the distribution chain. A balance must be struck between the cobalt supplier and the facility operator/customer that rests upon how much the customer needs to know about the intricacies of cobalt shipment. The objective of this paper is to highlight areas of possible business impact and reassure the users of sealed radiation sources that the global suppliers of these products are used to negotiating local variations in regulations governing the physical transportation of radiation sources, changes in regulations governing the design, manufacture and use of transportation containers and changes in the availability of commercial shippers and shipping routes. The major suppliers of industrial quantities of cobalt-60 are well placed to lead their customers through this complex process as a matter of routine

Evaluation of New Chemical Entities as Substrates of Liver Transporters in the Pharmaceutical Industry: Response to Regulatory Requirements and Future Steps.

Science.gov (United States)

Okudaira, Noriko

2017-09-01

This article discusses the evaluation of drug candidates as hepatic transporter substrates. Recently, research on the applications of hepatic transporters in the pharmaceutical industry has improved to meet the requirements of the regulatory guidelines for the evaluation of drug interactions. To identify the risk of transporter-mediated drug-drug interactions at an early stage of drug development, we used a strategy of reviewing the in vivo animal pharmacokinetics and tissue distribution data obtained in the discovery stage together with the in vitro data obtained for regulatory submission. In the context of nonclinical evaluation of new chemical entities as medicines, we believe that transporter studies are emerging as a key strategy to predict their pharmacological and toxicological effects. In combination with the recent progress in systems approaches, the estimation of effective concentrations in the target tissues, by using mathematical models to describe the transporter-mediated distribution and elimination, has enabled us to identify promising compounds for clinical development at the discovery stage.

Current status of regulatory aspects relating to water chemistry in Japanese NPPs

International Nuclear Information System (INIS)

Sato, Masatoshi

2014-01-01

In nuclear power plants, water chemistry of cooling water is carefully monitored and controlled to keep integrity of structures, systems and components, and to reduce occupational radiation exposures. As increasing demand for advanced application of light water cooled reactors, water chemistry control plays more important roles on plant reliability. The road maps on R and D for water chemistry of nuclear power systems have been proposed along with promotion of R and D related water chemistry in Japan. In academic and engineering societies, non-governmental standards for water chemistry are going to be established. In the present paper, recent trends of water chemistry in Japan have been surveyed. The effects of water chemistry on plant safety and radiation exposures have been discussed. In addition, possible contributions of regulation regarding water chemistry control have been confirmed. Major water chemistry regulatory aspects relating to reactor safety and radiation safety are also outlined in this paper. (author)

Regulatory aspects of sludge management

International Nuclear Information System (INIS)

Sharples, F.E.

1992-01-01

The paper presents an overview of radioactive waste land disposal restrictions by discussing the following topics: highlights of Resource Conservation and Recovery Act history; purposes of land disposal restrictions; regulatory definition of land disposal; US Environmental Protection Agency (EPA) implementation of land disposal restrictions; schedules for implementing land disposal restrictions; solvent and dioxin wastes; classification of liquid hazardous and radioactive wastes; generator and treatment, storage, and disposal responsibilities; variances and extensions; and options for mixed waste management. Land disposal restrictions take into account the long-term uncertainties associated with land disposal, the need to manage waste right the first time they are disposed, and the persistence toxicity, mobility, propensity to bioaccumulate, and volume. In the Department of Energy system land disposal restrictions affect mixed waste management and site remedial action programs

Regulatory authority of the Rocky Mountain states for low-level radioactive waste packaging and transportation

International Nuclear Information System (INIS)

Whitman, M.; Tate, P.

1983-07-01

The newly-formed Rocky Mountain Low-Level Radioactive Waste Compact is an interstate agreement for the management of low-level radioactive waste (LLW). Eligible members of the compact are Arizona, Colorado, Nevada, New Mexico, Utah, and Wyoming. Each state must ratify the compact within its legislature for the compact to become effective in that state and to make that state a full-fledged member of the compact. By so adopting the compact, each state agrees to the terms and conditions specified therein. Among those terms and conditions are provisions requiring each member state to adopt and enforce procedures requiring low-level waste shipments originating within its borders and destined for a regional facility to conform to packaging and transportation requirements and regulations. These procedures are to include periodic inspections of packaging and shipping practices, periodic inspections of waste containers while in the custody of carriers and appropriate enforcement actions for violations. To carry out this responsibility, each state must have an adequate statutory and regulatory inspection and enforcement authority to ensure the safe transportation of low-level radioactive waste. Three states in the compact region, Arizona, Utah and Wyoming, have incorporated the Department of Transportation regulations in their entirety, and have no published rules and regulations of their own. The other states in the compact, Colorado, Nevada and New Mexico all have separate rules and regulations that incorporate the DOT regulations. A brief description of the regulatory requirements of each state is presented

Nuclear Legislation in OECD and NEA Countries. Regulatory and Institutional Framework for Nuclear Activities - Greece

International Nuclear Information System (INIS)

2015-01-01

In Greece, there are no nuclear power plants and nuclear energy is not considered as an option in the foreseeable future. There is, however, one nuclear research reactor (in extended shutdown since 2014) and one sub-critical assembly. Radioactive waste originating from medicine, research and industry is classified as low level. Although there is no framework act dealing comprehensively with the different aspects of nuclear energy, there are various laws, decrees and regulations of a more specific nature governing several aspects of nuclear activities. This paper gives information on the general regulatory regime (mining regime, radioactive substances, nuclear fuel and equipment, nuclear installations (licensing and inspection, including nuclear safety, emergency response, trade in nuclear materials and equipment, radiation protection, radioactive waste management, nuclear security, transport, nuclear third party liability) and on the institutional framework with the regulatory and supervisory authorities (Greek Atomic Energy Commission (EEAE))

The operational and regulatory outlook for the transport of radioactive material

International Nuclear Information System (INIS)

Sousselier, Y.

1983-05-01

Future actions to achieve overall optimization with reasonable economic constraints are discussed in this paper. The knowledge of data used for design calculations of packaging should be improved. Another sector is that of taking into consideration the whole interlinked series of operations involved and not just the transport. Future regulations need not be more and more restrictive and detailed, but more and more effective. In the administrative aspects of regulations the documents should be simplified and their number reduced but checklists should be more detailed to show that operations have been done corectly. Optimum conditions should be pursued in quality control. These recommendations can only be put in practice if the general public is convinced that transporting radioactive materials is perfectly safe and that optimum conditions are in their interest

Regulatory and extra-regulatory testing to demonstrate radioactive material packaging safety

International Nuclear Information System (INIS)

Ammerman, D.J.

1997-01-01

Packages for the transportation of radioactive material must meet performance criteria to assure safety and environmental protection. The stringency of the performance criteria is based on the degree of hazard of the material being transported. Type B packages are used for transporting large quantities of radioisotopes (in terms of A 2 quantities). These packages have the most stringent performance criteria. Material with less than an A 2 quantity are transported in Type A packages. These packages have less stringent performance criteria. Transportation of LSA and SCO materials must be in open-quotes strong-tightclose quotes packages. The performance requirements for the latter packages are even less stringent. All of these package types provide a high level of safety for the material being transported. In this paper, regulatory tests that are used to demonstrate this safety will be described. The responses of various packages to these tests will be shown. In addition, the response of packages to extra-regulatory tests will be discussed. The results of these tests will be used to demonstrate the high level of safety provided to workers, the public, and the environment by packages used for the transportation of radioactive material

On five Bi-2223/Ag tapes with different aspect ratios from 5 to 26, AC losses have been measured at 77 K while a parallel AC magnetic field or a perpendicular AC magnetic field or a longitudinal AC transport current is applied. It has been found that at any frequency the perpendicular magnetic losses per cycle increase, but the parallel magnetic losses per cycle and the transport losses per cycle decrease as the aspect ratio increases. These experimental results are in accord with theoretical results. Meanwhile, we investigated the geometry dependence of the decay time constant of coupling current and that of full penetration field.

In most cases nuclear materials have to be shipped across the borders because at present neither an enrichment nor an industrial reprocessing plant exists in the Federal Republic of Germany. Transports are therefore carried out according to international standards, such as the IAEA recommendations laid down in legal traffic regulations. Control and physical protection are being exercised on the basis of national regulations. The paper summarizes the experience gained in performing quite a number of various shipments and deals with the application of the relevant transport regulations. It also gives a brief outlook on future aspects, such as the increasing transport volume, and transport problems related to decommissioning and the operation of a nuclear fuel cycle center

2013-01-01

A review has done for the Transportation Safety Plan (TSP) as one of the aspects of safety in the transport of nuclear materials. The review is necessary to harmonize national regulations with international practice. International practice of using TSP as one of the security requirements in addition to the Radiation Protection Program as a requirement of safety in the transport of nuclear materials. TSP is intended to ensure sound implementation of the transport of nuclear materials. TSP evaluation process can be done with a prescriptive approach, performance, and combinations. TSP contains information about administrative requirements, delivery security and response planning. TSP can be used to ensure the security of the implementation of the transport of nuclear materials effectively and efficiently. BAPETEN should require the applicant to submit the TSP as one document security requirements prior approval transporting nuclear materials. BAPETEN need to define the approach to the formulation and evaluation of TSP. BAPETEN need to set up an evaluation and inspection procedures for the implementation of TSP. (author)

Pukl, Radomír; Sajdlová, Tereza; Strauss, Alfred; Lehký, David; Novák, Drahomír

2017-09-01

Efficient techniques for both nonlinear numerical analysis of concrete structures and advanced stochastic simulation methods have been combined in order to offer an advanced tool for assessment of realistic behaviour, failure and safety assessment of transport structures. The utilized approach is based on randomization of the non-linear finite element analysis of the structural models. Degradation aspects such as carbonation of concrete can be accounted in order predict durability of the investigated structure and its sustainability. Results can serve as a rational basis for the performance and sustainability assessment based on advanced nonlinear computer analysis of the structures of transport infrastructure such as bridges or tunnels. In the stochastic simulation the input material parameters obtained from material tests including their randomness and uncertainty are represented as random variables or fields. Appropriate identification of material parameters is crucial for the virtual failure modelling of structures and structural elements. Inverse analysis using artificial neural networks and virtual stochastic simulations approach is applied to determine the fracture mechanical parameters of the structural material and its numerical model. Structural response, reliability and sustainability have been investigated on different types of transport structures made from various materials using the above mentioned methodology and tools.

NON-PROLIFERATION IMPACT ASSESSMENT FOR GNEP: ISSUES ASSOCIATED WITH TRANSPORTATION.

Energy Technology Data Exchange (ETDEWEB)

Radel, Ross; Rochau, Gary E

2008-03-01

This report evaluates transportation issues for nuclear material in the proposed Global Nuclear Energy Partnership (GNEP) fuel cycle. Since many details of the GNEP program are yet to be determined, this document is intended only to identify general issues. The existing regulatory environment is determined to be largely prepared to incorporate the changes that the GNEP program will introduce. Nuclear material vulnerability and attractiveness are considered with respect to the various transport stages within the GNEP fuel cycle. Physical protection options are then outlined for the transportation of this nuclear material. It is determined that increased transportation security will be required for the GNEP fuel cycle, particularly for international transport. Finally, transportation considerations for several fuel cycle scenarios are discussed. These scenarios compare the current "once-through" fuel cycle with various aspects of the proposed GNEP fuel cycle. 3

Spent Fuel Transportation Package Performance Study - Experimental Design Challenges

Snyder, A. M.; Murphy, A. J.; Sprung, J. L.; Ammerman, D. J.; Lopez, C.

2003-01-01

Numerous studies of spent nuclear fuel transportation accident risks have been performed since the late seventies that considered shipping container design and performance. Based in part on these studies, NRC has concluded that the level of protection provided by spent nuclear fuel transportation package designs under accident conditions is adequate. [1] Furthermore, actual spent nuclear fuel transport experience showcase a safety record that is exceptional and unparalleled when compared to other hazardous materials transportation shipments. There has never been a known or suspected release of the radioactive contents from an NRC-certified spent nuclear fuel cask as a result of a transportation accident. In 1999 the United States Nuclear Regulatory Commission (NRC) initiated a study, the Package Performance Study, to demonstrate the performance of spent fuel and spent fuel packages during severe transportation accidents. NRC is not studying or testing its current regulations, a s the rigorous regulatory accident conditions specified in 10 CFR Part 71 are adequate to ensure safe packaging and use. As part of this study, NRC currently plans on using detailed modeling followed by experimental testing to increase public confidence in the safety of spent nuclear fuel shipments. One of the aspects of this confirmatory research study is the commitment to solicit and consider public comment during the scoping phase and experimental design planning phase of this research

Safe and Secure Transportation of Radioactive Materials in Pakistan and Future Challenges

International Nuclear Information System (INIS)

Muneer, Muhammad; Ejaz, Asad

2016-01-01

PNRA is the sole organization in the country responsible to regulate all matters pertaining to ionizing radiations. For the safety of transport of radioactive material in the country, PNRA has adopted IAEA TS-R-1 as a national regulation. To cover the security aspects and emergency situations, if any, during the transportation of radioactive material, PNRA has issued the regulatory guide on ‘Transportation of Radioactive Material by Road in Pakistan’. In Pakistan, low to medium activity radioactive sources are transported from one place to another by road for the purpose of industrial radiography, well logging, medical application, etc. According to national policy, sealed radioactive sources of half life greater than 1 year and with initial activity of 100 GBq or more imported in the country are required to be returned to country of origin (exported) after its use. Although the activities related to transport of radioactive material remained safe and secure and no major accident/incident has been reported so far, however, the improvement/enhancement in the regulatory infrastructure is a continuous process. In future, more challenges are expected to be faced in the safety of transport packages. This paper will describe the steps taken by PNRA for the safety and security of transport of radioactive material in the country and future challenges. (author)

Compliance assurance for the safe transport of radioactive material. Safety guide

International Nuclear Information System (INIS)

2009-01-01

The objectives of this Safety Guide are to assist competent authorities in the development and maintenance of compliance assurance programmes in connection with the transport of radioactive material, and to assist applicants, licensees and organizations in their interactions with competent authorities. In order to increase cooperation between competent authorities and to promote the uniform application of international regulations and recommendations, it is desirable to adopt a common approach to regulatory activities. This Safety Guide is intended to assist in accomplishing such a uniform application by recommending most of the actions for which competent authorities need to provide in their programmes for ensuring compliance with the Transport Regulations. This Safety Guide addresses radiation safety aspects of the transport of radioactive material; that is, the subjects that are covered by the Transport Regulations. Radioactive material may have other dangerous properties, however, such as explosiveness, flammability, pyrophoricity, chemical toxicity and corrosiveness; these properties are required to be taken into account in the regulatory control of the design and transport of packages. Physical protection and systems for accounting for and control of nuclear material are also discussed in this Safety Guide. These subjects are not within the scope of the Transport Regulations, but information on them is included here because they must be taken into account in the overall regulatory control of transport, especially when the regulatory framework is being established. Section 1 informs about the background, the objective, the scope and the structure of this publication. Section 2 provides recommendations on the responsibilities and functions of the competent authority. Section 3 provides information on the various national and international regulations and guides for the transport of radioactive material. Section 4 provides recommendations on carrying out

It provides detailed compilations of international, federal, and state transportation-related regulations applicable to shipments originating at destined to Ohio facilities. This RFG was developed as an additional resource tool for use both by traffic managers who must ensure that transportation operations are in full compliance with all applicable regulatory requirements and by oversight personnel who must verify compliance activities.

Nuclear energy - some regulatory aspects

International Nuclear Information System (INIS)

Jennekens, Jon.

1980-03-01

The nuclear industry is often perceived by the public as being uniquely hazardous. As a consequence, the demands placed upon a nuclear regulatory agency invariably include sorting out the valid from the invalid. As the public becomes better informed, more time should become available for regulating the industry. The Canadian nuclear safety philosophy relies upon fundamental principle and basic criteria which licensees must show they are meeting at all stages in the development of a nuclear facility. In reactors, the concept of defence in depth involves the use of well-qualified personnel, compliance with national and international engineering codes and standards, the separation of process and safety systems, frequent testing of safety systems, redundancy in monitoring, control and initiation systems, multiple barriers against fission product release, and strict enforcement of compliance measurements. The Atomic Energy Control Board is writing a set of licensing guides to cover the whole nuclear fuel cycle; however, these will not lead to the impsition of a 'design by regulation' approach in Canada.

Adoptive transfer of T cells genetically modified by TCRs or CARs represents a highly attractive novel therapeutic strategy to treat malignant diseases. Various approaches for the development of such gene therapy medicinal products (GTMPs) have been initiated by scientists in recent years. To date, however, the number of clinical trials commenced in Germany and Europe is still low. Several hurdles may contribute to the delay in clinical translation of these therapeutic innovations including the significant complexity of manufacture and non-clinical testing of these novel medicinal products, the limited knowledge about the intricate regulatory requirements of the academic developers as well as limitations of funds for clinical testing. A suitable good manufacturing practice (GMP) environment is a key prerequisite and platform for the development, validation, and manufacture of such cell-based therapies, but may also represent a bottleneck for clinical translation. The German Cancer Consortium (DKTK) and the Paul-Ehrlich-Institut (PEI) have initiated joint efforts of researchers and regulators to facilitate and advance early phase, academia-driven clinical trials. Starting with a workshop held in 2016, stakeholders from academia and regulatory authorities in Germany have entered into continuing discussions on a diversity of scientific, manufacturing, and regulatory aspects, as well as the benefits and risks of clinical application of CAR/TCR-based cell therapies. This review summarizes the current state of discussions of this cooperative approach providing a basis for further policy-making and suitable modification of processes.

Nanotechnology can contribute to the development of innovative applications in the agriculture, food and feed sector by e.g. enabling improved delivery of nutrients or increased efficacy of agrichemicals. It is expected that applications will increase in the near future and may therefore become a relevant source of human exposure to nanomaterials (NM). To gain more up-to date information, RIKILT and the Joint Research Centre (JRC) were commissioned by the European Food Safety Authority (EFSA) to prepare an inventory of currently used and reasonably foreseen applications of NM in agriculture and food/feed production and carried out a review of regulatory aspects concerning NM in both EU and non-EU countries. An analysis of the information records in the inventory shows that nano-encapsulates, silver and titanium dioxide are the most frequent type of NM listed and that food additives and food contact materials are the most frequent types of application. A comparison between marketed applications and those in development indicates a trend from inorganic materials (e.g. silver) towards organic materials (nano-encapsulates, nanocomposites). Applications in novel food, feed additives, biocides and pesticides are currently mostly at a developmental stage. The review of EU and non-EU legislation shows that currently a few EU legal acts incorporate a definition of a nanomaterial and specific provisions for NM, whereas in many non-EU countries a broader approach is applied, which mainly builds on guidance for industry.

Control of intracellular heme levels: Heme transporters and Heme oxygenases

Science.gov (United States)

Khan, Anwar A.; Quigley, John G.

2011-01-01

Heme serves as a co-factor in proteins involved in fundamental biological processes including oxidative metabolism, oxygen storage and transport, signal transduction and drug metabolism. In addition, heme is important for systemic iron homeostasis in mammals. Heme has important regulatory roles in cell biology, yet excessive levels of intracellular heme are toxic; thus, mechanisms have evolved to control the acquisition, synthesis, catabolism and expulsion of cellular heme. Recently, a number of transporters of heme and heme synthesis intermediates have been described. Here we review aspects of heme metabolism and discuss our current understanding of heme transporters, with emphasis on the function of the cell-surface heme exporter, FLVCR. Knockdown of Flvcr in mice leads to both defective erythropoiesis and disturbed systemic iron homeostasis, underscoring the critical role of heme transporters in mammalian physiology. PMID:21238504

IAEA regulatory initiatives for the air transport of large quantities of radioactive materials

International Nuclear Information System (INIS)

Luna, R.E.; Wangler, M.W.; Selling, H.A.

1992-01-01

The International Atomic Energy Agency (IAEA) has been laboring since 1988 over a far reaching change to its model regulations (IAEA, 1990) for the transport of radioactive materials (RAM). This change could impact the manner in which certain classes of radioactive materials are shipped by air and change some of the basic tenets of radioactive material transport regulations around the world. The impetus for this effort was spawned in part by the decision of the Japanese government to move large quantities of reprocessed plutonium by air from France to Japan. The exploration of options for overflights of United States and Canadian airspace (among others) and landings in Anchorage, Alaska, generated intense debate in the US and countries that might have been overflown. The debate centered on general questions of the need to air transport plutonium in large quantities, package survival in an accident, prenotification, emergency response, routing, safeguards and other facets of the proposed operations. In the US, which already had the most stringent regulations for packaging of plutonium shipped by air (NUREG-0360), there was immediate additional legislative action to increase the stringency by requiring demonstration that an aircraft carrying plutonium in certified packagings could undergo a severe crash without release of plutonium (the Murkowski amendment). In the United Kingdom there was an official inquiry that resulted in a high visibility report (ACTRAM 88) and a conclusion that the IAEA should examine regulatory needs in the general area of air transport

Hollow density profile and particle transport of ECH plasmas in the low-aspect-ratio heliotron/torsatron CHS

International Nuclear Information System (INIS)

Iguchi, H.; Kubo, S.; Idei, H.

1993-01-01

Transport enhancement due to helical ripples is the main problem for a low-aspect-ratio helical system to survive as a magnetic fusion device. Optimization of the magnetic configuration has been experimentally studied for neutral beam heated plasmas in the Compact Helical System (CHS). A confinement regime compatible with the LHD scaling has been obtained by shifting the magnetic axis inward with respect to the minor axis of the helical windings. However a power balance analysis suggests that the improvement of plasma parameters has mainly been achieved by the improvement of power deposition. On the other hand, electron density profiles become peaked with the inward shifted magnetic axis in contrast to flattened profiles with the outward shifted one. A question arises: Does the magnetic structure really affect transport processes? In order to answer this question, it is most suitable to examine ECH plasmas in a low collisionality regime. In this paper we report some characteristics of the ECH plasmas in the low-aspect-ratio device CHS and discuss the effect of magnetic field ripples on transport processes. (author) 10 refs., 4 figs

A Review on Regulatory Enforcement Policy

Lim, Ji Han; Lee, Kyung Joo; Choi, Young Sung

2017-01-01

This paper examine the meaning and principle of enforcement through examples from other countries. Regulatory enforcement is the last stage of safety regulation and how it is exercised when one failing to meet regulatory requirements can have significant ripple effect across the industry. Thus, right philosophy and principle should be established. It is not recommended to emphasize neither deterrence approach nor behavior modification approach. This should be also taken into consideration when setting up the principle and system of regulatory enforcement. In the process of Vienna Declaration, Europe and the U.S showed the fundamental differences in their approaches to safety regulation. Considering this, it is required to remain cautious at all times on what to be improved in the aspect of internal consistency within our system and also in the aspect of procedure.

Regulatory signals for intestinal amino acid transporters and peptidases

International Nuclear Information System (INIS)

Ferraris, R.P.; Kwan, W.W.; Diamond, J.

1988-01-01

Dietary protein ultimately regulates many processes involved in protein digestion, but it is often unclear whether proteins themselves, peptides, or amino acids (AAs) are the proximate regulatory signal. Hence the authors compared several processes involved in protein digestion in mice adapted to one of three rations, identical except for containing 54% of either casein, a partial hydrolysate of casein, or a free AA mixture simulating a complete hydrolysate of casein. The authors measured brush-border uptakes of seven AAs that variously serve as substrates for four AA transporters, and brush-border and cytosolic activities of four peptidases. The three rations yielded essentially the same AA uptake rates. Peptidase activities tended to be lower on the AA ration than on the protein ration. In other studies, all three rations yielded the same rates of brush-border peptide uptake; protein is only modestly more effective than AAs at inducing synthesis of pancreatic proteases; and, depending on the animal species, protein is either much less or much more effective than AAs at stimulating release of cholecystokinin and hence of pancreatic enzymes. Thus the regulators of each process involved in protein digestion are not necessarily that process's substrate

Legal and regulatory possibility of connection between interstate natural gas distribution networks instead of constructing transport pipelines; Possibilidade juridoco-regulatoria da conexao interestadual entre redes de distribuicao de gas natural como alternativa a construcao de gasodutos de transporte

According to Revista Brasil Energia (2011a), the local natural gas distribution concessionaire in the State of Sao Paulo Gas Brasiliano Distribuidora - GBD, plans to expand its distribution pipeline network in western Sao Paulo up to the border of the State of Minas Gerais, near the region known as Minas Triangle where a connection with the pipeline network of the State of Minas Gerais' natural gas distribution company, Companhia de Gas de Minas Gerais - GASMIG shall be built in order to supply natural gas to an ammonia plant to be built by PETROBRAS in the City of Uberaba. Still according to the publication, the project described above would be an alternative to the construction of a transportation pipeline that, since the enforcement of the Gas Law - Law No. 11.909/09 (Brasil, 2009), should be subject to concession contracts preceded by a complex, and probably delayed, planning and procurement. However, there is a transportation pipeline project, deriving from the Bolivia-Brazil transportation pipeline near the city of Sao Carlos, in Sao Paulo, crossing the Minas Triangle and finishing in the State of Goias. This project is owned by TGBC Company. The existence of two gas pipeline projects with very similar paths to supply virtually the same regions and based on different regulatory frameworks, one consisting of a connection between the distribution networks of different States and another based on the concept of pipeline transportation of gas under the legal and regulatory federal jurisdiction raises the discussion about the possibility of legal and regulatory interstate connections of distribution pipeline networks as an alternative to planning, allocation and construction of a transportation pipelines. This article aims to examine the legal and regulatory foundations of both alternatives and delineate the limits of performance of States and Federal Government on legislation and regulation concerning the movement of natural gas pipeline through the Country

Welfare aspects in rabbit rearing and transport

Claudio Cavani

2010-01-01

Full Text Available The review starts with the description of the rabbits’ (Oryctolagus cuniculus main habits and the current situation concerning the rabbit husbandry and management systems, as well as their effects on the welfare of these animals. As far as the intensive rabbit husbandry systems are concerned, the main problems are related to the time since rabbits have been domesticated and their adaptive capacity and coping styles as respects the farming environment and management systems. Both these aspects have implications in the present and future of rabbit rearing for different purposes. Examples are given on the effects of different housing and management systems on rabbit welfare, as well as examples of the ethological, physiological and productive indicators used to evaluate these effects. Transportation and, more generally, preslaughter phases including catching, fasting and lairage at the abattoir are considered major stressors for farmed rabbits and might have deleterious effects on health, well-being, performance, and finally, product quality. A general statement of the recent scientific studies considering the effects of pre-slaughter factors on physiological and productive measurements are reported. Finally, some indications in order to improve rabbit welfare, already present at the European level, are also outlined, together with the European Food Safety Authority opinions.

For adaptation between anaerobic, micro-aerobic and aerobic conditions Escherichia coli's metabolism and in particular its electron transport chain (ETC) is highly regulated. Although it is known that the global transcriptional regulators FNR and ArcA are involved in oxygen response it is unclear how they interplay in the regulation of ETC enzymes under micro-aerobic chemostat conditions. Also, there are diverse results which and how quinones (oxidised/reduced, ubiquinone/other quinones) are controlling the ArcBA two-component system. In the following a mathematical model of the E. coli ETC linked to basic modules for substrate uptake, fermentation product excretion and biomass formation is introduced. The kinetic modelling focusses on regulatory principles of the ETC for varying oxygen conditions in glucose-limited continuous cultures. The model is based on the balance of electron donation (glucose) and acceptance (oxygen or other acceptors). Also, it is able to account for different chemostat conditions due to changed substrate concentrations and dilution rates. The parameter identification process is divided into an estimation and a validation step based on previously published and new experimental data. The model shows that experimentally observed, qualitatively different behaviour of the ubiquinone redox state and the ArcA activity profile in the micro-aerobic range for different experimental conditions can emerge from a single network structure. The network structure features a strong feed-forward effect from the FNR regulatory system to the ArcBA regulatory system via a common control of the dehydrogenases of the ETC. The model supports the hypothesis that ubiquinone but not ubiquinol plays a key role in determining the activity of ArcBA in a glucose-limited chemostat at micro-aerobic conditions.

Forecasting of the radioactive material transport demand for the Brazilian Nuclear Program and the security aspects

International Nuclear Information System (INIS)

Meldonian, Nelson Leon

1979-01-01

In the nuclear fuel cycle, a lot of radioactive materials are produced. These radioactive materials must be transported in order to promote the integration of the fuel cycle units. Considerations about the transport characteristics of radioactive material were made for each section of the fuel cycle. These considerations were based on the experience of several countries and in accordance with the International Atomic Energy Agency regulations. A prediction of transport demands for the Brazilian Nuclear Program until year 2.010 was made. The prediction refers mainly to the quantity of radioactive material produced in each section of the cycle the quantity of vehicles needed for the transport of these materials. Several safety aspects were considered specially, the accidents predictions for years 2.000 and 2.010. The accident probability in Brazilian railroads and highways was compared with that of the USA.

The waste management plants include three high level waste immobilisation plants, one in operation, one under commissioning and one more under construction. Atomic Energy Regulatory Board is mandated to review and authorise from the safety angle the siting, the design, the construction and the operation of the waste management plants. The regulatory procedures, which involve multi-tier review adopted for ensuring the safety of these facilities, are described in this paper. (author)

Regulatory aspects and experience with Russian research reactors

International Nuclear Information System (INIS)

Morozov, S.I.

2003-01-01

Regulatory activity of Gosatomnadzor of Russia in the field of research reactors (RR) safety implies implementing three major aspects: 1) establishing the nuclear and radiation safety standards; 2) licensing; and 3) inspection and enforcement. Relatively recently a full set of safety standards and regulations for RR has been established thus allowing Gosatomnadzor of Russia to effectively implement its designated functions in the field of RR safety. A minimum set of these documents is shown as follows: Level I: Fundamentals: Law 'On the use of nuclear energy'; Law 'On Public radiation protection' Level II: Safety Standard: 'General Provisions for Safety of Research Facilities' Level III: Safety Rules: Nuclear Safety; - Radiation Safety; Waste Management; Safe Decommissioning of RR; Safety Analysis Report; QAP Level IV: Safety Regulations: Licensing (incl. Peer Review and Safety Assessment) - Inspection Gosatomnadzor of Russia has created and regularly updates the database on nuclear research reactors based on the actual status of all facilities. According to the database many facilities have been shutdown during recent years whether temporary or permanently waiting for the final decision on their decommissioning. For example, in 2003 Gosatomnadzor of Russia has 85 nuclear research reactors under its supervision (compared to 113 in 1998). This fact can be explained by three main reasons: 1) experimental program finished and no other programmes in place; 2) lack of resources (financial and human); 3) safety problems (physical obsolescence and ageing of equipment). One of the main difficulties in regulating RR safety is a variety of operating organizations - 21, with different financial and human resource capabilities. Ministries responsible for supporting their operation are of a little help. It becomes obvious that a unified governmental program for RR utilization is urgently needed to decide what number of RR and for what needed purposes is required to support the

Regulatory aspects of the Leak Before Break application

Korosec, D.; Vojvodic Tuma, J.

2000-01-01

In the present paper the Leak Before Break (LBB) methodology is described on the way, as it was evaluated in Slovenian Nuclear Safety Administration in the process of the nuclear power plant (NPP) Krsko modernization process. In the recent decade, reviewed regulatory position regarding elimination the dynamic effects of the postulated primary coolant pipe ruptures in some countries was issued. The basis for such new approach are research achievements on different areas of science like metallurgy, fracture mechanics, dynamic analysis and testing of materials. By this new regulatory position the utility has the possibility to adopt LBB concept, but has to fulfill at least general prerequisites, described in standard review plan, where the basic principles and objectives of the evaluation process are described. World wide practice shows that more intensive and detailed evaluation is necessary as it is described in the standard review plan. The concerns and requests raising during evaluation of the consequences of the adopted LBB concept have generally some common points comparing regulatory experience of different countries which have already accepted this methodology or are currently under the process of evaluation. But nevertheless every nuclear power plant is unique, comparing specific material properties, dynamic analysis assumptions, safety analyses performed etc. One of the most important areas in the LBB evaluation process is reliable primary piping material evaluation. Several generic material studies were performed and the applicability of these studies for the justification of LBB has to be carefully performed. Elimination of the double ended guillotine break from the safety analysis has very strong impact to the safety analysis results and finally to the structures, systems and components too. Nuclear safety administration has made a lot of effort to make its position on this methodology clear. The expertise of the authorized institutions is in such process

1985-10-01

An Advisory Group by IAEA and FAO on Regulatory and Technological Requirements for Authorization of the Food Irradiation Process was held at IAEA Headquarters in Vienna from 5 to 9 November 1984. The task of the Advisory Group was to advise on the scientific and technological considerations affecting the implementation of the food irradiation process, with particular reference to the facilitation of international trade in irradiated foods and to develop guidance on how the various provisions of the Codex General Standard on Irradiated Foods could be incorporated into national legislation in order to facilitate international trade and avoid the occurence of trade barriers. Separate abstracts were prepared for the various presentations at this meeting

UK Nirex Ltd is developing a range of reusable shielded transport containers (RSTCs) to ensure the safe transport of immobilised intermediate level waste to a future UK deep repository for disposal. The RSTCs use an inset lid for mechanical strength and radiation shielding, but the containment boundary is provided by a separate lid seal member (LSM). The LSM is a semi-flexible steel diaphragm surrounded by a rim which carries a double O-ring seal. The LSM rim is clamped to a flat mating surface on the container body. A finite element model has been developed for an RSTC with a wall thickness of 285 mm, in order to assess its containment performance in 9m regulatory drop tests (IAEA 1996). The challenge was to predict the size of small gaps that might appear between the LSM rim and the RSTC body seal face ; this level of detail would be 1-2 orders of magnitude smaller than the displacements experienced in the impact zone. The model was first validated against a series of one-third scale model drop tests of the RSTC. The validated model was then analysed for 9m regulatory impacts in the six worst impact attitudes. The behavior of the LSM was assessed for each attitude and the seal face (gaps) between the LSM and the body were determined. Although small gaps of about 0.5 mm are predicted, it is likely that containment would be preserved. (authors)

KAERI promoted the construction of a research reactor, SMART-P, the reduced scale of SMART, with intent to demonstrate the safety and performance of SMART. According to this progress, the development of regulatory process for SMART-P became necessary. The establishment of regulatory policy, based on the current regulatory guidelines as well as technical aspect, became essential matters. Considering the on-going small and medium size reactors in near future, the selection of the appropriate measure in the existing regulatory process to SMART-P is very important. Thus the schematic study for the applicable licensing procedure and regulatory requirements suitable for SMART-P is required.

2000-01-01

District heating is one of the most interesting fields of geothermal energy application development in Europe. However, besides the technical/technological/economical and organizational aspects of the problem in question, the related legal and regulatory aspects influence very much the real possibilities for wider introduction of this energy source in the state energy balances in most of the countries. Based on the official EU report for the State-of-the-art of the problem of the insurance to cover geological risks and necessary aspects to be developed and resolved in a better and 'common' way in order to enable higher investments in bigger projects (district heating) development, the paper presents the situation in different European countries in relation to the Macedonian one. Conclusions extracted should give a positive contribution to the process of the Macedonian laws accommodation to the common EU practice. (Author)

Regulatory aspects and activities in the field of radioactive waste management in Bulgaria

International Nuclear Information System (INIS)

Kastchiev, G.

2001-01-01

Bulgaria uses nuclear power for electricity generation and for a variety of nuclear applications in industry, research and medicine. Six WWER type Nuclear Power Plants (NPPs) went into operation at Kozloduy between 1974 and 1991. Until 1988 spent fuel was transported back to the former Soviet Union, but since then has been stored on site. Operational low level waste is stored on site, but since 1993 a volume reduction strategy using supercompaction has been employed, which has reduced stored waste volumes by a factor of four. Institutional radioactive wastes are disposed at the Novi Han near surface repository, located 35 km from Sofia. It was commissioned in 1964 and is now about half full. Siting studies have begun for a new near surface repository that would accept both institutional and NPP waste. A legislative and regulatory framework, as well as organizational and institutional arrangements, are in place. A national strategy that includes provisions for compiling a national inventory of spent fuel and radioactive waste and provisions for funding spent fuel and radioactive waste management, has been developed. The paper elaborates on the current situation regarding radioactive waste management in Bulgaria. (author)

Safety aspects of long-term dry interim storage of type-B spent fuel and HLW transport casks

International Nuclear Information System (INIS)

Wolff, D.; Probst, U.; Voelzke, H.; Droste, B.; Roedel, R.

2004-01-01

Based on the German decision to minimise transports of spent fuel casks between nuclear power plants, reprocessing plants and central storage facilities several on-site storage facilities have been licensed till the end of 2003. Because of the large amount of type-B transport casks which are going to be used for long-term interim storage the question of time limited type-B license maintenance during the storage period of up to 40 years has been discussed under different aspects. This paper describes present technical aspects of the discussion. A main aspect of transport cask qualification for interim storage is the long-term behaviour of the metallic seal lid system. Concerning this results from current experimental long-term tests with metallic ''Helicoflex''-seals in which pool water is enclosed are presented. The test series has been performed by the Federal Institute for Materials Research and Testing (BAM) on behalf of the Federal Office for Radiation Protection (BfS) since 2001. Finally, the paper presents a German concept for an authorities' and technical experts' exchange of experience, know-how and state of the art referring to cask dispatch in nuclear facilities. BAM has taken over a central role in this so-called ''co-ordinating institution for cask dispatching information'' (''KOBAF'') which contains an online data base and a technical working group meeting twice a year. The goal is to keep comparable technical standards for all nuclear sites and storage facilities which are going to load and dispatch casks of the same or similar types under the responsibility of different German state governments for the next decades

Ethical and regulatory aspects of embryonic stem cell research.

Science.gov (United States)

Jain, Kewal K

2002-12-01

Ethical and regulatory issues concerning embryonic stem (ES) cell research are reviewed here a year after the controversy became a public and political issue in the US. The background of various issues are examined and the current regulations in various countries are reviewed. In the US, the debate is linked with abortion, as well as the status of a fetus as a human being, and is politically driven. Obtaining stem cells from embryonic tissues involves destruction of the embryo, to which objections are raised. Religious beliefs are examined and no serious impediments to ES cell research could be identified. Regulations vary from one country to another and it is unlikely that there will ever be any universally uniform ethical and regulatory standards for ES cell research. Currently, the most liberal and favourable environments for ES cell research are in the UK, Singapore, Sweden, India, Israel and China. Unless the US liberalises ES cell research, it may lose its lead in ES cell research and investments in this area may drift to countries with better environments for research. Suggestions are offered in this review to improve the ethical environment for ES cell research.

Initiatives in transport cask licensing

International Nuclear Information System (INIS)

Patterson, John

1998-01-01

The variations in research reactor fuel form, configuration, irradiation characteristics, and transport cask have required a substantial number of transport cask licensing actions associated with foreign research reactor spent fuel transportation. When compounded by limited time for shipment preparations, due to contract timing or delayed receipt of technical data, the number and timing of certifications has adversely impacted the ability of regulatory agencies to support intended shipping schedules. This issue was brought into focus at a april, 1998 meeting among DOE, the US Nuclear Regulatory Commission, and DOE's spent fuel transportation contractors. (author)

This document covers assessment of those aspects of a radiation protection and safety infrastructure that are implemented by the Regulatory Authority for radiation sources and practices using such sources and necessarily includes those ancillary technical services, such as dosimetry services, which directly affect the ability of the Regulatory Authority to discharge its responsibilities. The focus of the guidance in this TECDOC is on assessment of a regulatory programme intended to implement the BSS. The BSS address transportation and waste safety mainly by reference to other IAEA documents. When conducting an assessment, the Review Team members should be aware of the latest IAEA documents (or similar national documents) concerning transportation and waste safety and, if appropriate, nuclear safety, and take them into account to the extent applicable when assessing the effectiveness of the regulatory programme governing radiation protection and safety of radiation source practices in a particular State.

Regulatory issues and assumptions associated with polymers for subsurface barriers surrounding buried waste

International Nuclear Information System (INIS)

Heiser, J.; Siskind, B.

1993-01-01

One of the options for control of contaminant migration from buried waste sites is the construction of a subsurface barrier that consists of a wall of low permeability material. Subsurface barriers will improve remediation performance by removing pathways for contaminant transport due to groundwater movement, meteorological water infiltration, vapor- and gas-phase transport, transpiration, etc. Subsurface barriers may be used to open-quotes directclose quotes contaminant movement to collection sumps/lysimeters in cases of unexpected remediation failures or transport mechanisms, to contain leakage from underground storage tanks, and to restrict in-situ soil cleanup operation and chemicals. Brookhaven National Laboratory is currently investigating advanced polymer materials for subsurface barriers. This report addresses the regulatory aspects of using of non-traditional polymer materials as well as soil-bentonite or cement-bentonite mixtures for such barriers. The regulatory issues fall into two categories. The first category consists of issues associated with the acceptability of subsurface barriers to the Environmental Protection Agency (EPA) as a method for achieving waste site performance improvement. The second category encompasses those regulatory issues concerning health, safety and the environment which must be addressed regarding barrier installation and performance, especially if non-traditional materials are to be used. Since many of EPA's concerns regarding subsurface barriers focus on the chemicals used during installation of these barriers the authors discuss the results of a search of the Federal Register and the Code of Federal Regulations for references in Titles 29 and 40 pertaining to key chemicals likely to be utilized in installing non-traditional barrier materials. The use of polymeric materials in the construction industry has been accomplished with full compliance with the applicable health, safety, and environmental regulations

A validated large-eddy simulation model was employed to study the effect of the aspect ratio and ground heating on the flow and pollutant dispersion in urban street canyons. Three ground-heating intensities (neutral, weak and strong) were imposed in street canyons of aspect ratio 1, 2, and 0.5. The detailed patterns of flow, turbulence, temperature and pollutant transport were analyzed and compared. Significant changes of flow and scalar patterns were caused by ground heating in the street canyon of aspect ratio 2 and 0.5, while only the street canyon of aspect ratio 0.5 showed a change in flow regime (from wake interference flow to skimming flow). The street canyon of aspect ratio 1 does not show any significant change in the flow field. Ground heating generated strong mixing of heat and pollutant; the normalized temperature inside street canyons was approximately spatially uniform and somewhat insensitive to the aspect ratio and heating intensity. This study helps elucidate the combined effects of urban geometry and thermal stratification on the urban canyon flow and pollutant dispersion.

Regulatory Impact Assessment (RIA and Rationality of Law – Legal Aspects

Directory of Open Access Journals (Sweden)

Jan Chmielewski

2015-06-01

Full Text Available Purpose: The fundamental aim of this article is to verify an assumption according to which the proper Regulatory Impact Assessment (RIA is a key factor in the rationality of law. Rational law is a law which is effective and able to realize and achieve social, economic and environmental aims determined and established by the lawmaker. Methodology: The scope of this paper – which determines its structure – encompasses the definition of RIA, including its specific (but non-legal forms such as benchmarking and evaluation. As far as we are concerned, these methods can provide – as a kind of Regulatory Impact Assessment a significant tool for measuring the rationality of regulations. Furthermore, the usefulness of benchmarking and evaluation has been recognised by representatives of jurisprudence. We will also explain the concept and the assumptions of the rationality of law on the grounds and in the light of the case law of the Polish Constitutional Tribunal and the Supreme Administrative Court. This should allow to countercheck the main thesis of this paper. The methodology encompasses primary legal methods such as literature, case law and legislation analysis. Findings: An indispensable condition of the rationality of law is actual elimination of irrational regulations which were not subjected to the Regulatory Impact Assessment. Practical implications: Although RIA is a problematic issue (in terms of its practical application,it is necessary to carry it out in order to assure the rationality of law. A good and desirable complement to Regulatory Impact Assessment are non-legal methods such as benchmarking and evaluation. Originality: Originality and value of this survey lies in taking into account the case law of the Polish Constitutional Tribunal and the Supreme Administrative Court. Additionally, this paper is original in that it considers non-legal methods in the examination of the rationality of law.

Legal aspects of transport of nuclear materials

Jacobsson, Mans.

The Paris Convention and the Brussels Supplementary Convention are briefly discussed and other conventions in the field of civil liability for nuclear damage are mentioned: the Vienna Convention, the Nuclear Ships Convention and the 1971 Convention relating to civil liability in the field of maritime carriage of nuclear material. Legislation on civil liability in the Nordic countries, which is based on the Paris Convention and the Supplementary Convention is discussed, notably the principle of channelling of liability and exceptions from that principle due to rules of liability in older transport conventions and certain problems due to the limited geographical scope of the Paris Convention and the Supplementary Convention. Insurance problems arising in connection with transport of nuclear materials are surveyed and an outline is given of the administrative provisions concerning transport (based on the IAEA transport regulations) which govern transport of radioactive materials by different means: road, rail, sea and air. Finally, the 1968 Treaty on the Non-Proliferation of Nuclear Weapons is discussed. (NEA) [fr

[The prevalence of hearing impairment in transport workers and peculiarities of management of occupational loss of hearing (as exemplified by the situation in the air and railway transport)].

Science.gov (United States)

Pankova, V B; Skryabina, L Yu; Kas'kov, Yu N

2016-01-01

This article presents data on the prevalence of hearing impairment among the workers engaged in the main means of transportation(air and railway transport). They show that the relative frequency of occupational loss of hearing in the cockpit members of commercial aviation amounts to one third of all cases of analogous diseases in this country. The main professional groups of transport works suffering from hearing impairment are constituted by the representatives of the so-called elite specialities, such as flying crew personnel, locomotive engineers, and their assistants. This fact constitutes an important aspect (not only of medical but also of socio-economic significance) of the problem under consideration. The high prevalence of professional hearing impairment among the transport workers is attributable to the high noise level in the cabins of locomotives and aircraft cockpits as well as to the inadequate expert and diagnostic work or imperfection of the regulatory documentation.

The U.S. Nuclear Regulatory Commission (NRC) was established in 1974 with the mission to license and regulate the civilian use of nuclear materials for commercial, industrial, academic, and medical uses in order to protect public health and safety, and the environment, and promote the common defense and security. Currently, approximately half (∼49%) of the workforce at the NRC has been with the Agency for less than six years. As part of the Agency's mission, the NRC has partial responsibility for the oversight of the transportation and storage of radioactive materials. The NRC has experienced a significant level of expertise leaving the Agency due to staff attrition. Factors that contribute to this attrition include retirement of the experienced nuclear workforce and mobility of staff within or outside the Agency. Several knowledge management (KM) initiatives have been implemented within the Agency, with one of them including the formation of a Division of Spent Fuel Storage and Transportation (SFST) KM team. The team, which was formed in the fall of 2008, facilitates capturing, transferring, and documenting regulatory knowledge for staff to effectively perform their safety oversight of transportation and storage of radioactive materials, regulated under Title 10 of the Code of Federal Regulations (10 CFR) Part 71 and Part 72. In terms of KM, the SFST goal is to share critical information among the staff to reduce the impact from staff's mobility and attrition. KM strategies in place to achieve this goal are: (1) development of communities of practice (CoP) (SFST Qualification Journal and the Packaging and Storing Radioactive Material) in the on-line NRC Knowledge Center (NKC); (2) implementation of a SFST seminar program where the seminars are recorded and placed in the Agency's repository, Agency-wide Documents Access and Management System (ADAMS); (3) meeting of technical discipline group programs to share knowledge within specialty areas; (4

The increasing use of nuclear power and public interest in the safety controls led to the proposal by the sub-Committe on Licensing of the NEA Committee on the Safety of Nuclear Installations for a specialist meeting on regulatory inspection practices. This report which was prepared at the request of the sub-Committee to assist in the exchange of views and experience at the meeting reviews the response to a questionnaire on the systems employed, the scope and objectives and the effort involved in regulatory inspection throughout all stages of the life of a nuclear power plant. Other aspects of regulatory inspection activities are discussed including documentation, procedures for changes in technical specification and modifications to plant, powers and duties of regulatory inspection personnel and actions to be taken in the event of an accident or emergency. The report concludes with some comments on those aspects of regulatory inspection practices where further information and an exchange of experience might prove to be beneficial to Member countries.

Regulatory compliance in the design of packages used to transport radioactive materials

International Nuclear Information System (INIS)

Raske, D.T.

1993-01-01

Shipments of radioactive materials within the regulatory jurisdiction of the US Department of Energy (DOE) must meet the package design requirements contained in Title 10 of the Code of Federal Regulations, Part 71, and DOE Order 5480.3. These regulations do not provide design criteria requirements, but only detail the approval standards, structural performance criteria, and package integrity requirements that must be met during transport. The DOE recommended design criterion for high-level Category I radioactive packagings is Section III, Division 1, of the ASME Boiler and Pressure Vessel Code. However, alternative design criteria may be used if all the design requirements are satisfied. The purpose of this paper is to review alternatives to the Code criteria and discuss their applicability to the design of containment vessels in packages for high-level radioactive materials. Issues such as design qualification by physical testing, the use of scale models, and problems encountered using a non-ASME design approach are addressed

Transport of nuclear materials: a major stake for the reprocessing-conditioning-recycling strategy

As the international reference in terms of fuel cycle services, the COGEMA Group has developed a wide range of industrialized products answering to its clients needs. But, as deregulation and competition are now expanding, utilities has to be perfectly aware of the cost level of their strategic choices, and to keep these costs down. This point is especially valid in the back-end of the fuel cycle. Several leading nuclear countries around the world have chosen the reprocessing-recycling option because it ensures a economically mastered vision. In that respect, transportation reliability is consequently a basic requirement. It ensures a balanced and continuous flows of materials. Transportation system must be reliable in terms of schedule, safety or industrial aspects (i.e. dedicated packaging for road, rail, sea or air transports, maintenance aspects...). Any serious flaw in one of these three points could lead to delays, thus lessening the economic advantage for utilities. But, one must not loose sight that transportation of nuclear materials is tied to extra-technical issues, such as environmental or regulatory factors, which are fundamental for a consistent understanding of this business. The COGEMA Group, through its subsidiary Transnucleaire, possesses a dedicated transport system, widely praised for its constant commitment in terms of safety, quality and operating. This papers presents the overall back-end transportation framework and details the transport organisations as well as the main achievements of Transnucleaire when it comes to sea, road or rail back-end transports.

Hale, J.

1995-01-01

Quality Assurance (QA) is a requirement of the International Atomic Energy Agency (IAEA) Safety Series No. 6 ''Regulations for Safe Transport of Radioactive Materials.'' It is also, increasingly, a customer requirement. British Nuclear Fuels plc (BNFL) Transport Division has established an integrated management system (including quality and safety) which is being extended to cover environmental aspects. The management system covers the design, procurement, manufacture, testing, documentation, use, maintenance, inspection and decommissioning of all packages used for the transport of radioactive materials and for interim storage. It also covers planning, programming and transport operations. These arrangements cover all modes of transport by road, rail, sea and air. The QA arrangements developed enable Transport Division to demonstrate to Competent Authorities, customers and the general public that the systems in place meet all regulatory requirements. This paper discusses what quality assurance is, why QA arrangements should be introduced and how they were established within Transport Division. Finally, the further developments in the Division's quality arrangements using the tools and techniques of Total Quality Management (TQM) and the European Foundation for Quality Management Model for Self Assessment are described

E-learning, an abbreviation of electronic learning, indicates the provision of education and training on the Internet or the World Wide Web. The impact of networks and the Internet on radiology is undoubtedly important, as it is for medicine as a whole. The Internet offers numerous advantages compared with other mass media: it provides access to a large amount of information previously known only to individual specialists; it is flexible, permitting the use of images or video; and it allows linking to Web sites on a specific subject, thus contributing to further expand knowledge. Our purpose is to illustrate the regulatory aspects (including Internet copyright laws), current radiological applications and future prospects of e-learning. Our experience with the installation of an e-learning platform is also presented. We performed a PubMed search on the published literature (without time limits) dealing with e-learning tools and applications in the health sector with specific reference to radiology. The search included all study types in the English language with the following key words: e-learning, education, teaching, online exam, radiology and radiologists. The Fiaso study was referred to for the regulatory aspects of e-learning. The application of e-learning to radiology requires the development of a model that involves selecting and creating e-learning platforms, creating and technologically adapting multimedia teaching modules, creating and managing a unified catalogue of teaching modules, planning training actions, defining training pathways and Continuing Education in Medicine (CME) credits, identifying levels of teaching and technological complexity of support tools, sharing an organisational and methodological model, training the trainers, operators' participation and relational devices, providing training, monitoring progress of the activities, and measuring the effectiveness of training. Since 2004, a platform--LiveLearning--has been used at our

Safety aspects of long-term dry interim storage of Type B spent fuel and high-level transport casks

Based on the German decision to minimise transport of spent fuel casks between nuclear power plants, reprocessing plants and central storage facilities several on-site storage facilities were licensed until the end of 2003. Because of the large amount of Type B(U) transport casks which are going to be used for long-term interim storage the question of time-limited Type B(U) licence maintenance during the storage period of up to 40 years has been discussed under different aspects. This paper describes present technical aspects of the discussion. A main aspect of qualification of transport casks for interim storage is the long-term behaviour of the metallic seal-lid system. Here we present results from current long-term experimental tests with metallic 'Helicoflex' seals in which pool water is enclosed. This series of tests has been performed by the Federal Institute for Materials Research and Testing (BAM) on behalf of the Federal Office for Radiation Protection (BfS) since 2001. Finally, the paper presents a German concept for an exchange of experience, know-how and state-of-the-art between authorities and technical experts with regard to cask dispatch in nuclear facilities. BAM has taken over a central role in this so-called 'coordinating institution for cask dispatching information' ('KOBAF') which entails management of an online database of cask-specific documents and a technical working group meeting twice a year. The goal is to keep comparable technical standards for all nuclear sites and storage facilities which are going to load and dispatch casks of the same or similar types under the responsibility of different German state governments for the coming decades.

Nuclear energy has been regulated by various international agreements or treaties due to the potential dangers. In case of export or import of nuclear material, it is important to comply with international norms and domestic laws related to nonproliferation and physical protection of nuclear material. Because, if non-compliant, it can be taken nuclear sanctions from the international community, and thus the domestic nuclear activities can be under a negative impact. Recently, international interests in nuclear security have been increased, it has become very sensitive to whether or not to join, and to comply with international treaties during international transportation of nuclear materials. Currently it is not discussed yet how to present and interpret the relevant provisions in CPPNM. However, it is necessary to prepare for the dispute among the parties that we don't know when it happens.

Regulatory frameworks for decentralised energy

International Nuclear Information System (INIS)

Woodman, Bridget; Baker, Philip

2008-01-01

This paper considers aspects of the current regulatory frameworks for markets and infrastructure which can inhibit the deployment of decentralised energy. The government has stated that decentralised energy can make a positive contribution to reducing the UK's carbon emissions, but recognises that at the moment the technologies face market and regulatory barriers. If it is to become a viable alternative to centralised generation, energy market design and the regulation of energy infrastructure will have to evolve to ensure that decentralised options are no longer locked out.

Developing regulatory approaches

International Nuclear Information System (INIS)

Axelsson, Lars

2012-01-01

Lars Axelsson presented SSM progress on oversight of LMfS/SC since the Chester 1 Workshop in 2007. Current SSM approaches for safety culture oversight include targeted safety management and safety culture inspections, compliance inspections which cover aspects of safety management/safety culture and multi-disciplinary team inspections. Examples of themes for targeted inspections include management of ambiguous operational situations or other weak signals, understanding of and attitudes to Human Performance tools, the Safety Department's role and authority and Leadership for safety. All regulatory activities provide inputs for the SSM yearly safety evaluation of each licensee. A form has been developed to capture safety culture observations from inspections and other interactions with licensees. Analysis will be performed to identify patterns and provide information to support planning of specific Safety Culture activities. Training has been developed for regulatory staff to enhance the quality of regulatory interventions on safety culture. This includes a half-day seminar to provide an overview of safety culture, and a workshop which provides more in-depth discussion on cultural issues and how to capture those during regulatory activities. Future plans include guidance for inspectors, and informal seminars on safety culture with licensees

Australian Experience in Implementing Transport Safety Regulations and Transport Security Recommendations

International Nuclear Information System (INIS)

Sarkar, S.

2016-01-01

Australian transport safety and security regulatory framework is governed by Commonwealth, State and Territory legislations. There are eleven competent authorities in Australia that includes three Commonwealth authorities, six states and two territory authorities. IAEA Regulations for Safe Transport of Radioactive Material (TS-R-1, 2005 edition) is applied through Australian Radiation Protection and Nuclear Safety Agency (ARPANSA) Code of Practice for Transport of Radioactive Material 2008 by road, rail and waterways not covered by marine legislations. All states and territories apply this Transport Code through their regulatory system. For air transport, the Civil Aviation Act 1988 adopts the requirements of the ICAO Technical Instructions for the Safe Transport of Dangerous Goods by Air DOC 9284, which also adopts TS-R-1. The security of radioactive material in air transport is achieved via the Aviation Transport Security Act 2004. For sea transport Australian Marine Order 41 applies the requirements of IMDG (International Maritime Dangerous Goods) Code which also adopts TS-R-1. The security of radioactive material (nuclear material) is governed by two Commonwealth Agencies namely, ARPANSA and ASNO (Australian Safeguards and Non-proliferation Office) . ARPANSA regulates the security of radioactive sources through ARPANSA Code of Practice for the Security of Radioactive Sources 2007 which is based on the IAEA Draft Security Series. ASNO regulates security of nuclear material including U, Th and Pu through the Nuclear Non-Proliferation (Safeguards) Act, and the object of which is to give effect to certain obligations that Australia has as a party to the NPT, Australia’s safeguards agreement with the IAEA, and other bilateral safeguards agreements and certain obligations that Australia has as a party to the Convention for the Physical Protection of Nuclear Materials (CPPNM). This paper presents the effectiveness of regulatory approaches for safe and secure

Regulatory Inspection (RI) of BARC facilities and projects are carried out under the guidance of BARC Safety Council (BSC) Secretariat. Basically facilities and projects have been divided into two board categories viz. radiological facilities and non-radiological facilities. The Rls of radiological facilities should be carried out under OPSRC and of non-radiological facilities under CFSRC. Periodicity of inspection shall be at least once in a year. The RI of projects is carried out under concerned DSRC. RI practices with industrial safety which includes electrical, mechanical, material handling and conventional aspect for these facilities starts with check lists. The inspection areas are prepared in the form of checklists which includes availability of approved documents, compliance status of previous RIT and various safety committee's recommendations, radiological status of facilities, prompt reporting of safety related unusual occurrences, major incident, site visit for verification of actual status of system/plant. The practices for inspection in the area of electrical safety shall include checking of maintenance procedure for all critical class IV system equipment's such as HT panel, LT panel, transformer and motors. Load testing of Class III system such as D.G. set etc. shall be carried out as technical specification surveillance schedule. Status of aviation lights, number of qualified staff, availability of qualified staff etc. shall be form of inspection

Mass transport aspects of polymer electrolyte fuel cells under two-phase flow conditions

Energy Technology Data Exchange (ETDEWEB)

Kramer, D.

2007-03-27

This work deals with selected aspects of mass transport phenomena in PEFCs and DMFCs. Emphasis is placed on the implications originating from the occurrence of two-phase flow within these devices. Optimality of supply, distribution, and removal of the fuel, the oxidant, and the reaction products is of utmost importance for the stability, efficiency, and durability of the devices. Being a prerequisite for high current densities while maintaining sufficient voltage, mass transport optimization contributes to the development of cost effective as well as compact designs and hence competitive fuel cells. [German] Die Visualisierung und Quantifizierung von Fluessigwasseransammlungen in Polymerelektrolytmembran-Brennstoffzellen konnte mittels Neutronenradiographie erreicht werden. Dank dieser neuartigen diagnostischen Methode konnte erstmals die Fluessigwasseransammlung in den poroesen Gasdiffusionsschichten direkt nachgewiesen und quantifiziert werden. Die Kombination von Neutronenradiographie mit ortsaufgeloesten Stromdichtemessungen bzw. lokaler Impedanzspektroskopie erlaubte die Korrelation des inhomogenen Fluessigwasseranfalls mit dem lokalen elektrochemischen Leistungsverhalten. Systematische Untersuchungen an Polymerelektrolyt- und Direkt-Methanol-Brennstoffzellen verdeutlichen sowohl den Einfluss von Betriebsbedingungen als auch die Auswirkung von Materialeigenschaften auf die Ausbildung zweiphasiger Stroemungen.

Federal, state, and local regulation of radioactive-waste transportation: Progress toward a definition of regulatory authority

International Nuclear Information System (INIS)

Livingston-Behan, E.A.

1986-01-01

The supremacy clause, the commerce clause, and the equal-protection guarantees of the U.S. Constitution establish the basic framework for defining the authority of Federal, State, and local governments to regulate the transportation of radioactive waste. Court decisions and advisory rulings of the U.S. Department of Transportation (DOT) suggest that State and local regulation of the transportation of spent nuclear fuel and high-level radioactive waste is precluded under supremacy-clause principles to the extent that such regulation addresses nuclear safety or aspects of transportation that are already specifically regulated by the Federal government. Even where State and local requirements are found to be valid under the supremacy clause, they must still satisfy constitutional requirements under the commerce and equal-protection clauses. Despite stringent standards of review, State and local transportation requirements have been upheld where directly related to the traditional exercise of police powers in the area of transportation. Legitimate State and local police-power activities identified to date by the DOT and the courts include inspection and enforcement, immediate accident reporting, local regulation of traffic, and certain time-of-day curfews. The extent to which State and local permitting requirements and license fees may be determined valid by the DOT and the courts remains unclear. Continued clarification by the DOT and the courts as to the validity of permits and fees will serve to further define the appropriate balance for Federal, State, and local regulation of radioactive-waste transportation

Assessment of regulatory effectiveness. Peer discussions on regulatory practices

International Nuclear Information System (INIS)

1999-09-01

regulatory approaches of the regulatory body and its organization are important factors. Whilst regulatory effectiveness cannot easily be measured directly, there are various characteristics which can be attributed to an effective regulatory body. These characteristics can be used as indicators. They can also provide guidance on the assessment of regulatory effectiveness. They may also indicate possible fields of enhancement of the effectiveness of a regulatory body. In order to assist Member States in achieving and maintaining a high level of regulatory effectiveness, the IAEA convened the seventh series of peer discussions on 'Assessment of Regulatory Effectiveness'. The results and findings of these discussions are summarized in this report which concentrates on common findings and good practices identified during the discussions. Its intention is primarily to disseminate information on existing experience and to identify beneficial aspects of practices in order to provide guidance to Member States. This report is structured so that it covers the subject matter under the following main headings: Elements of an Effective Regulatory Body; Possible Indicators of Regulatory Effectiveness; Assessment and Suggestions for Good Practices to Enhance Effectiveness. It is important to note that recommendations of good practice are included if they have been identified by at least one of the groups. It does not follow that all of the groups or individual Member States would necessarily endorse all of the recommendations. However, it is considered that if a single group of senior regulators judge that a particular practice is worthy of recommendation, it needs to receive serious consideration. In some cases the same recommendations arise from all of the groups. These are considered to be particularly meritorious

Current status and regulatory aspects of pesticides considered to be persistent organic pollutants (POPs) in Taiwan.

Science.gov (United States)

Tsai, Wen-Tien

2010-10-01

Organochlorine pesticides (OCPs) are capable of persisting in the environment, transporting between phase media and accumulating to high levels, implying that they could pose a risk of causing adverse effects to human health and the environment. Consequently, most OCPs are designated as persistent organic pollutants (POPs) and even as endocrine disrupting chemicals (EDCs). The objective of this paper was to review the current status of pesticide POPs in Taiwan, including aldrin, chlordane, chlordecone, DDT, dieldrin, endrin, heptachlor, hexachlorobenzene, α/β-hexachlorocyclohexanes, lindane, mirex, pentachloro-benzene, and toxaphene. The information about their environmental properties, banned use, carcinogenic toxicity and environmental levels, can be connected with the regulatory infrastructure, which has been established by the joint-venture of the central competent authorities (i.e., Environmental Protection Administration, Department of Health, Council of Agriculture, and Council of Labor Affairs). The significant progress to be reported is that the residual levels of these pesticide-POPs, ranging from trace amounts to a few ppb, have declined notably in recent years.

Radioactive substances have many beneficial applications, ranging from power generation to uses in medicine, industry and agriculture. As a rule, they are produced in different places from where they are used, needing to be transported. In order for transport to take place safely and efficiently, national and international standards must be complied with. This research aims to assess the safety analysis processes for the transport of radioactive material carried out by the regulatory body in Brazil, from the point of view of their compliance with the International Atomic Energy Agency (IAEA) standards. The self-assessment methodology named SARIS, developed by the AIEA, was used. The following steps were carried out: evaluation of the Diagnosis and Processes Mapping; responses to the SARIS Question Set and complementary questions; SWOT analysis; interviews with stakeholders and evaluation of a TranSAS mission conducted by the IAEA in 2002. Considering only SARIS questions, processes are 100% adherent. The deepening of the research, however, led to the development of twenty-two improvement proposals and the identification of nine good practices. The results showed that the safety analysis processes of the transport of radioactive material are being carried out in a structured, safe and reliable way but also that there is much opportunity for improvement. The formulation of an action plan, based on the presented proposals, can bring to the regulatory body many benefits. This would be an important step towards convening an external evaluation, providing greater reliability and transparency to the regulatory body´s processes. (author)

Recent Status of Indonesian Nuclear Regulatory System Development in Responding the Results of IRRS Mission

BAPETEN as Nuclear Energy Regulatory Agency of Indonesia faces challenges in performing its tasks for assuring the safety, security, and safeguards in nuclear energy utilization through the regulatory system. Based on the recent IRRS mission to Indonesia, hosted by BAPETEN, several recommendations and suggestions shall require special attention to provide strategic action plans in following them up. Some of the recommendations include the necessity of the Government to develop and document a national policy and strategy for safety, to provide BAPETEN with human and financial resources to ensure adequate discharge of its statutory regulatory obligations, to ensure that prime responsibility of safety is assigned to the person or organization responsible for a facility or an activity through the legal framework, to ensure appropriate coordination and liaison between BAPETEN and other relevant authorities in the areas of medical application of radiation and transport of radioactive material. The suggestions cover, among others, the need of having a graded approach policy in implementing all regulatory functions, clarifying the responsibility of the individual reporting on the performance of the management system to senior management, establishing procedures for assessing the safety and appropriateness of the working environment and enhancing the implementation of self-assessments by including safety culture aspects. As part of the action plans, BAPETEN is currently drafting the national policy and strategy on nuclear and radiation safety. Furthermore, BAPETEN is revising the existing act on nuclear energy in order to assign the prime responsibility of safety to be borne by the licensees, to ensure the adequacy of its human and financial resources, and to provide clearer distinction of responsibilities between BAPETEN and other relevant authorities in the areas of medical application of radiation and transport of radioactive material. To counter the issue on

The electronic transport properties of the delafossite oxides ? are usually understood in terms of two well-separated entities, namely the triangular ? and (? layers. Here, we review several cases among this extensive family of materials where the transport depends on the interlayer coupling and displays unconventional properties. We review the doped thermoelectrics based on ? and ?, which show a high-temperature recovery of Fermi-liquid transport exponents, as well as the highly anisotropic metals ?, ?, and ?, where the sheer simplicity of the Fermi surface leads to unconventional transport. We present some of the theoretical tools that have been used to investigate these transport properties and review what can and cannot be learned from the extensive set of electronic structure calculations that have been performed.

Barriers and drivers of new interconnections between EU and non-EU electricity systems. Economic and regulatory aspects

International Nuclear Information System (INIS)

Van Werven, M.J.N.; Van Oostvoorn, F.

Interconnection of different electricity systems offers several advantages and benefits. In the first place it provides reliability and increases the robustness of the system. Furthermore, it increases economic efficiency and reduces the possibility to abuse market power. Price differences are the signal that efficiency gains can be obtained. To make a sound decision whether to invest in new interconnection capacity, the causes behind the price differences should be well understood. Price differences must originate from structural, long-term causes. Differences in primary resources, fuel mix and load patterns are such causes. It is important to note that price differences that result from the difference between regulatory structures (lack of level playing field) may not be structural and therefore may not justify investment in interconnection capacity. Next to advantages and benefits, interconnection is faced with costs and barriers. Firstly, there are investment costs, which are high for building new interconnections, and there are energy losses that are caused by transporting electricity. A third possible barrier is congestion within the EU, which impedes the imported electricity to freely flow to demand areas (and hinders the export of electricity to neighbouring regions). Furthermore, interconnection may create loop flows. In addition, interconnection could lead to an increasing import dependency, which may create political resistance. And finally, there may be opposition from residents in the areas where the transmission and interconnection lines have to be built. Concerning regulatory issues, trade between markets is more likely to be impeded or distorted if market designs and rules between countries/regions differ substantially. Regulatory issues that are of relevance comprise rules concerning the timing of gate closure, imbalance arrangements, the firmness of transmission access rights, the type of tariff regulation, unbundling, the ownership of

2013-01-01

The OECD Nuclear Energy Agency (NEA) Committee on Nuclear Regulatory Activities (CNRA) Working Group on Public Communication of Nuclear Regulatory Organisations (WGPC) organised the workshop 'Crisis communication: facing the challenges' on 9-10 May 2012 in Madrid to address the international dimension of the communicative responses to crises by assessing the experience of Nuclear Regulatory Organisations of the NEA member countries and their stakeholders. The CNRA/WGPC also prepared in 2011, before the Fukushima-Daiichi nuclear accident occurred, a Road Map for Crisis Communication of Nuclear Regulatory Organisations which focused only on national aspects. This 'road map' had not considered the international dimension. CNRA mandated the WGPC to expand the Road Map so as to conclude the follow-up activity on crisis communication. The objective of the present document is to firstly, identify the key messages which can be extracted from three surveys carried out among the WGPC members after Fukushima-Daiichi's accident (Appendices II, III and IV), and incorporate them into the Road Map for Crisis Communication. Secondly, the good practices on public communication of NROs, which were presented during the OECD/NEA Workshop on Crisis Communication: Facing the Challenges, are reported. Following the structure of the road map for public communication responses during crisis included in the NEA report entitled 'Road Map for Crisis Communication of Nuclear Regulatory Organisations - National aspects', the good practices on communication before, during and after a crisis are provided. Overall, the emphasis of this report is on the international aspects of crisis communication, rather than the national dimension. (authors)

1994-12-01

The purpose of this resource guide is to provide a convenient reference document of information that may be useful to the U.S. Department of Energy (DOE) and DOE contractor personnel involved in packaging and transportation activities. An attempt has been made to present the terminology of DOE community usage as it currently exists. DOE`s mission is changing with emphasis on environmental cleanup. The terminology or nomenclature that has resulted from this expanded mission is included for the packaging and transportation user for reference purposes. Older terms still in use during the transition have been maintained. The Packaging and Transportation Resource Guide consists of four sections: Sect. 1, Introduction; Sect. 2, Abbreviations and Acronyms; Sect. 3, Definitions; and Sect. 4, References for packaging and transportation of hazardous materials and related activities, and Appendices A and B. Information has been collected from DOE Orders and DOE documents; U.S Department of Transportation (DOT), U.S. Environmental Protection Agency (EPA), and U.S. Nuclear Regulatory Commission (NRC) regulations; and International Atomic Energy Agency (IAEA) standards and other international documents. The definitions included in this guide may not always be a regulatory definition but are the more common DOE usage. In addition, the definitions vary among regulatory agencies. It is, therefore, suggested that if a definition is to be used in a regulatory or a legal compliance issue, the definition should be verified with the appropriate regulation. To assist in locating definitions in the regulations, a listing of all definition sections in the regulations are included in Appendix B. In many instances, the appropriate regulatory reference is indicated in the right-hand margin.

Performance-Based (Risk-Informed) Regulation: A Regulatory Perspective

International Nuclear Information System (INIS)

Kadambi, N. Prasad

2005-01-01

Performance-based regulation (PBR) has been mandated at the national level in the United States and at the agency level, where appropriate, at the U.S. Nuclear Regulatory Commission (USNRC). Guidance has been developed that implements the USNRC's definitions of PBR and other such conceptual regulatory improvements. This paper describes why PBR is important, what constitutes PBR in the context of direction provided at the USNRC, and how PBR can be implemented using a five-step process. The process steps articulate questions to be posed by the analyst regarding various aspects of a regulatory issue so that a suitably performance-based resolution can be developed. A regulatory alternative thus developed can be included among other options to be considered as part of the regulatory decision-making process

Regulatory control, nuclear safety regulation and waste management in Spain

Martin, A.

2000-01-01

This article presents the challenges that faces the spanish regulatory authority. The deregulation of electricity industry imposes severe changes in nuclear power economics and forces nuclear power to compete with other sources of electricity. A pressure is perceived for regulatory effectiveness primarily since the cost of regulation is a component of the cost of the product. This effectiveness gain in regulatory control will be reached through systematic strategic analysis, formulation and implementation. The regulatory aspects of plant life extension and of waste management are examined

Full Text Available Many factors should be considered when selecting the mode of transport. Cost is always important, but must bemeasured against the quality of, and potential losses incurred in, transport. Quality assurance during transportationalso plays a critical role in the health and welfare of beef cattle, as proper handling and transport of cattle can reducesickness in calves, prevent bruises, and improve the quality of the meat from these animals. Provide transportation thatavoids undue stress as appropriate to each species. Transportation, as a whole, is a stress factor that generatesnervousness and anxiety. Any animal reacts with alarm before a new situation such as transportation and this isaggravated when the loading and unloading conditions are not the most favourable. We must always prevent the animalfrom suffering unnecessarily. Once some of the animals from the fattening lot have reached a considerable size and inline with market demand for this type of meat, slaughtering beings. They are slaughtered according to consumer ortrade demand. Animal slaughtering consists of two phases: stunning and bleeding.

The US Department of Energy Office of Civilian Radioactive Waste Management is developing a Multi-Purpose Canister system to promote compatibility between the waste program elements of storage, transportation, and disposal. The development of a Multi-Purpose Canister system requires meeting various regulatory requirements. These regulatory requirements are set forth in environmental and Nuclear Regulatory Commission (NRC) regulations. This paper discusses the more significant regulatory issues that must be addressed in the development of a Multi-Purpose Canister system by the Department of Energy

Jones, Christopher

2015-01-01

Most vaccines, including the currently available glycoconjugate vaccines, are administered to healthy infants, to prevent future disease. The safety of a prospective vaccine is a key prerequisite for approval. Undesired side effects would not only have the potential to damage the individual infant but also lead to a loss of confidence in the respective vaccine-or vaccines in general-on a population level. Thus, regulatory requirements, particularly with regard to safety, are extremely rigorous. This chapter highlights regulatory aspects on carbohydrate-based vaccines with an emphasis on analytical approaches to ensure the consistent quality of successive manufacturing lots.

The physical aspects of the quality guarantee in Nuclear Medicine and Radiotherapy its are of cardinal importance to guarantee the quality of the diagnoses and treatments that are carried out to the patients in this type of services. The OIEA, the OMS and other scientific and professional organizations have contributed significantly to the elaboration of recommendations, Protocols, etc. applicable in the quality control programs and safety of the Nuclear Medicine and Radiotherapy departments. In spite of the great effort developed in this sense the Installation of the programs of quality control and safety of the Nuclear Medicine and Radiotherapy departments can fail if the same ones are not based in three decisive elements that are: the existence of national regulations, the existence of the infrastructure required for it and the existence of enough qualified personnel to develop this programs. The present work shows the regulatory focus that on this topic, it has followed the National Center of Nuclear Safety of Cuba (CNSN). The same left of strengthen all the existent Synergies in the different organizations of the country and it went in two fundamental directions: installation of the regulatory requirements that govern this activity and the Authorization of a Cuban Entity, specialized in carrying out audits to the quality control and safety programs of the Nuclear Medicine and Radiotherapy departments. After 4 work years in this direction, the results confirm the validity of the experience developed by the CNSN, at the moment all the services of Nuclear Medicine and Radiotherapy of Cuba possess quality control and safety programs, these programs are annually Auditing by an Authorized entity by the CNSN and the Inspectors of the Regulatory Authority, control, during the inspections, the one execution of the established requirements in the national regulations. The work developed so far can serve, modestly, of reference to others countries of Latin America that

The present paper aims at shedding some light on the concept of `sustainable transport`. Within the context of a sustainable development, the consequences of interdependencies between transport, infrastructure, economy and environment for the formulation of optimal regulatory policies are investigated. The Spatial Price Equilibrium approach is adapted for the analysis of sustainable spatio-economic development, and for the evaluation of first-best and second-best regulatory policies on the issues at hand. The analysis demonstrates the need for integration of elements concerning economic structure, infrastructure, transportation, environment and space in one single analytical framework when considering questions on sustainability in relation to transport. 2 figs., 1 appendix, 10 refs.

The Radiosynoviortesis is a to therapeutic proceed that consists in the injection of a radiopharmaceutical beta transmitter in the synovial cavity of the articulations affected by arthropaties. With it is achieved to cause the fibrosis and remodeling of the synovial membrane obtaining a remarkable improvement in the patients that it includes the disappearance of the pain and the increase of the flexibility of the treated articulation. The technique began to be carried out from 1952 in Europe when it was injected Au 196 in patients affected by rheumatoid arthropaties and starting from then it has gone winning followers in Canada, United States, Australia and some countries of Latin America. Their results are satisfactory and they have been endorsed by the practice. In Cuba it was carried out at November 16, 2002 a clinical essay with the use of this technique, the same one was Graduate by the National Center of Nuclear Safety, in their condition of Regulatory Authority, for it the National Institute of Hematology and Immunology presented the technical documentation that bases its safety. However for the generalization of this technique and their inclusion in the Nuclear Medicine services already existent, the Regulatory Authority has indicated a group of requirements that should be kept in mind in a such way that the application of the Radiosynoviortesis fulfills the Regulation of those 'Basic Norms of Radiological Safety' effective in our country. The present work exposes the particularities and challenges that the Radiosynoviortesis outlines from the point of view of the Radiological Protection, as well as the technical aspects that should be kept in mind for its Licensing, in such way that the is guaranteed safety of the same one in the relative thing to the radiological protection of the patients, those workers and the one publishes. The work reaffirms the feasibility of this to therapeutic proceed from the point of view of the radiological protection, proposing

Baszo, Z.

2010-01-01

The paper deals with the regulatory aspect of Nuclear Power Plant (NPP) Periodic Safety Review (PSR) as a part of license renewal process in the Slovak Republic. It summarizes the history of activities similar to PSR performed in the past for NPPs operated in the Slovak Republic. Furthermore, it describes both the requirements involved in the current Slovak legislation to be met by licensee in the Slovak Republic in this field and the procedures concerning the PSR as well. The objective and rules of PSR to be performed for NPPs in the Slovak Republic were derived from the internationally accepted International Atomic Energy Agency (IAEA) document and have been implemented into national legislation. PSR of two twin units located in Bohunice NPP and Mochovce NPP, respectively, has been initiated in the Slovak Republic based on evaluation of each area to be reviewed (safety factors) using recent methodology and practice. Other significant factors, such as ageing, modifications of NPP and the safe operation for a specified future period, have to be assessed in the frame of PSR. Report on performed PSR outlines the results of review for each area, the corrective plan, which considering mutual relations between assessed areas specifies the issues to be solved with the aim to eliminate shortcomings identified in the frame of PSR and to adopt safety improvements. The findings from PSR in the evaluated areas also serve as a source of information for updating of all documents to be attached to the written application of licensee for renewal of a nuclear power plant operating license. The presented procedure describes how the Nuclear Regulatory Authority of the Slovak Republic (UJD SR) has reviewed the documents submitted during PSR. Based on results of submitted documents evaluation and licensee application for license renewal the license for next 10 years operation has been issued for Bohunice NPP. At present, similar procedure for Mochovce NPP unit 1 and 2 is underway.(author).

Full Text Available Biomolecular pathways are built from diverse types of pairwise interactions, ranging from physical protein-protein interactions and modifications to indirect regulatory relationships. One goal of systems biology is to bridge three aspects of this complexity: the growing body of high-throughput data assaying these interactions; the specific interactions in which individual genes participate; and the genome-wide patterns of interactions in a system of interest. Here, we describe methodology for simultaneously predicting specific types of biomolecular interactions using high-throughput genomic data. This results in a comprehensive compendium of whole-genome networks for yeast, derived from ∼3,500 experimental conditions and describing 30 interaction types, which range from general (e.g. physical or regulatory to specific (e.g. phosphorylation or transcriptional regulation. We used these networks to investigate molecular pathways in carbon metabolism and cellular transport, proposing a novel connection between glycogen breakdown and glucose utilization supported by recent publications. Additionally, 14 specific predicted interactions in DNA topological change and protein biosynthesis were experimentally validated. We analyzed the systems-level network features within all interactomes, verifying the presence of small-world properties and enrichment for recurring network motifs. This compendium of physical, synthetic, regulatory, and functional interaction networks has been made publicly available through an interactive web interface for investigators to utilize in future research at http://function.princeton.edu/bioweaver/.

Capture and storage of CO2 (CCS) has been studied as an option in the portfolio of climate change mitigation strategies for about 20 years. Although the technical maturity of CCS is generally less than other mitigation options, such as renewable energy or energy efficiency, many of the CCS components are generally regarded as mature enough for deployment. CCS, however, has a number of other aspects that may inhibit its deployment. The aim of the ACCSEPT project is to identify the main gaps in knowledge in the non-technical aspects of CCS, to research them, and to propose recommendations to address them. Although in the recent past several large and influential reports have been published in the field of CCS, many of them have focussed on the technical aspects of CCS. The IPCC Special Report on CCS did not have the mandate to address policy aspects and could only touch upon public perception issues. An IEA report focussed on the costs and economic aspects of CCS and touched upon regulatory and risk issues, but was at the time of publication unable to dive deep into it. This report provides a critical literature review for the non-technical aspects of CCS in the following categories: (a) Legal issues: National and international legislation relevant to CCS. Examples include national drinking water and mining laws, and the London Convention (Chapter 2). (b) Regulatory issues: National and international policies in the field of energy or climate change that can act as support mechanisms for CCS (Chapter 3). (c) Costs and economics: Addresses the question whether the current costs assumed for CCS are interpreted correctly, and reviews the assumptions made in economic models informing the policymaking process (Chapter 4). (d) Social and acceptability issues: A review of all studies currently done that focus on public perception of CCS. Methods used are questionnaires with lay public, focal group discussions, and expert polls (Chapter 5). (e) Crosscutting issues: CCS as a

Regulatory aspects of the enforcement policy applied to teletherapy equipment obsolescence (1995-2002)

The paper describes the way in which the Nuclear Regulatory Authority (ARN) has implemented an 'enforcement' policy for the services of radiotherapy that operated obsolete cobalt therapy units. Without doubt one of the greater advances has been the simulation and planning of the treatment, indispensable tools in a system of quality in radiotherapy where the equipment acquires a preponderant paper. In Argentina the distribution of equipment was inhomogeneous, and within it coexisted, as primary and unique units, great amount with a technology today already obsolete. The Nuclear Regulatory Authority (ARN) took a strong regulatory attitude directed to change or to retire many of the units, as its characteristics of design and antiquity did not fulfill the criteria of radiological security established in the norms (optimization of the dose, distances source to skin, yield in surface, adequate maintenance, etc.). On this matter a policy was applied to impose within suitable terms, the change of the obsolete equipment for this practice, particularly those distances source to skin minor than 80 cm. As result of the applied coercive measures at this moment, 28 equipment of cobalt therapy in advanced degree of obsolescence were retired by regulatory decision. Part of these equipment were replaced by their owners by more modern equipment whose operation adjusts to the requirements of the radiological security norm, whereas the majority was replaced by linear accelerators. At the moment there are 86 of cobalt therapy units and 52 accelerators operating in our country, against 104 and 32 respectively, that operated in 1995. (author)

Current Status and Regulatory Aspects of Pesticides Considered to be Persistent Organic Pollutants (POPs in Taiwan

2010-10-01

Full Text Available Organochlorine pesticides (OCPs are capable of persisting in the environment, transporting between phase media and accumulating to high levels, implying that they could pose a risk of causing adverse effects to human health and the environment. Consequently, most OCPs are designated as persistent organic pollutants (POPs and even as endocrine disrupting chemicals (EDCs. The objective of this paper was to review the current status of pesticide POPs in Taiwan, including aldrin, chlordane, chlordecone, DDT, dieldrin, endrin, heptachlor, hexachlorobenzene, α/β-hexachlorocyclohexanes, lindane, mirex, pentachloro-benzene, and toxaphene. The information about their environmental properties, banned use, carcinogenic toxicity and environmental levels, can be connected with the regulatory infrastructure, which has been established by the joint-venture of the central competent authorities (i.e., Environmental Protection Administration, Department of Health, Council of Agriculture, and Council of Labor Affairs. The significant progress to be reported is that the residual levels of these pesticide-POPs, ranging from trace amounts to a few ppb, have declined notably in recent years.

Expression and Regulation of Drug Transporters and Metabolizing Enzymes in the Human Gastrointestinal Tract.

Science.gov (United States)

Drozdzik, M; Oswald, S

2016-01-01

Orally administered drugs must pass through the intestinal wall and then through the liver before reaching systemic circulation. During this process drugs are subjected to different processes that may determine the therapeutic value. The intestinal barrier with active drug metabolizing enzymes and drug transporters in enterocytes plays an important role in the determination of drug bioavailability. Accumulating information demonstrates variable distribution of drug metabolizing enzymes and transporters along the human gastrointestinal tract (GI), that creates specific barrier characteristics in different segments of the GI. In this review, expression of drug metabolizing enzymes and transporters in the healthy and diseased human GI as well as their regulatory aspects: genetic, miRNA, DNA methylation are outlined. The knowledge of unique interplay between drug metabolizing enzymes and transporters in specific segments of the GI tract allows more precise definition of drug release sites within the GI in order to assure more complete bioavailability and prediction of drug interactions.

Schedules for Regulatory Regimes

Austvik, Ole Gunnar

The idea of regulating transporters' terms of operations is that if the market itself does not produce optimal outcomes, then it can be mimicked to do so through regulatory and other public instruments. The first-best solution could be a subsidized (publicly owned) enterprise that sets tariffs according to marginal costs. This has been the tradition in many European countries in the aftermath of WW2. Due to lack of innovative pressure on and x-inefficiency in these companies, this solution is today viewed as inferior to the system of regulating independent (privately owned) firms. When the European gas market becomes liberalized, part of the process in many countries is to (partially) privatise the transport utilities. Privatised or not, in a liberalized market, the transport utilities should face an independent authority that overviews their operations not only in technical, but also in economic terms. Under regulation, a ''visible hand'' is introduced to correct the imperfect market's ''invisible hand''. By regulating the framework and conditions for how firms may operate, public authorities seek to achieve what is considered optimal for the society. The incentives and disincentives given for pricing and production should create mechanisms leading to an efficient allocation of resources and ''acceptable'' distribution of income. As part of intervening into firms' behavior, regulation may be introduced to direct the firm to behave in certain ways. The framework and regulatory mechanisms for the market must then be constructed in a way that companies voluntarily produce an amount at a price that gives maximal profits and simultaneously satisfies social goals. The regulations should lead to consistency between the company's desire to maximize profits and the society's desire for maximizing welfare, as in a perfectly competitive market. This is the core of regulatory economics

The heavy transportation in Brazil is generally done by highways. The radioactive material transportation follow this same rule. Whenever a radioactive material is carried by the road, by the sea or by the air, in some cases, a kind of combination of those transportation ways, the transport manager has to create a Transportation Plan and submit it to CNEN. Only after CNEN's approval, the transportation can be done. The plan must have the main action on Radiation Protection, giving responsibilities and showing all the directing that will be take. Although, the Brazilian's highways are not in good conditions, one could say that some of them are not good enough for any kind of transportation. But we are facing radioactive material use increase but the hospitals and industries, that the reason it's much more common that kind of transportation nowadays. So, because of that, a special attention by the governments must be provide to those activities. This paper goal is to show the real conditions of some important highways in Brazil in a radioactive protection's perspective and give some suggestions to adjust some of those roads to this new reality.

Safety culture competition - expectations of a regulatory authority

International Nuclear Information System (INIS)

Keil, D.; Gloeckle, W.

2000-01-01

The accident at the Chernobyl nuclear power station on April 26, 1986 influenced the development of reactor safety and promulgated two basic concepts especially in Germany. On the one hand, extensive measures of in-plant accident management have greatly reduced the so-called residual risk. On the other hand, a comprehensive safety approach has been initiated which comprises the nuclear power plant as a system together with people, technology, and organization and also includes safety culture. In a modern regulatory concept based on the dynamic development of safety, the authority's classical regulatory function of controlling is supplemented by the objective of promoting safety. While preserving the division of responsibilities between the regulatory authority and plant operators, the authority uses 'constructive critical dialog' as a tool to enhance safety. Besides the regulatory assessment of safety culture on the basis of indications or indicators, also the continuous promotion of safety culture in a dialog with plant operators is seen as one of the duties of a regulatory authority. Continued efforts are necessary to maintain the high level of safety culture in German nuclear power plants. Operators are expected to establish a safety management which assigns top priority to safety issues, and which pursues the goal of supervising and promoting safety culture. Developments on the deregulated electricity markets must not lead to safety aspects ranking second to economic aspects. Moreover, also under changed boundary conditions, only the safe operation of nuclear power plants ensures economic viability. (orig.) [de

Heavy metal transport processes in surface water and groundwater. Geochemical and isotopic aspects

International Nuclear Information System (INIS)

Tricca, A.

1997-01-01

This work deals with the transport mechanisms of trace elements in natural aquatic systems. The experimental field is situated in the Upper Rhine Rift Valley because of the density and variety of its hydrological net. This study focused on three aspects: the isotopic tracing with Sr, Nd and O allowed to characterize the hydro-system. The 87 Sr/ 86 Sr and 143 Nd/ 144 Nd ratios show that the system is controlled by two natural end members a carbonate and a silicate one and a third end member of anthropogenic origin. The isotopic data allowed also to investigate the exchange processes between the dissolved and the particulate phases of the water samples. Because of their use in the industry and their very low concentrations in natural media, the Rare Earth Elements (REE) are very good tracers of anthropogenic contamination. Furthermore, due to their similar chemical properties with the actinides,they constitute excellent analogues to investigate the behaviour of fission products in the nature. In this study we determined the distribution of the REE within a river between the dissolved, the colloidal and the particulate phases. Among the REE of the suspended load, we distinguished between the exchangeable and the residual REE by means OF IN HCl leading experiments. The third topic is the investigation of uranium series disequilibrium using α-Spectrometry. The determination of ratios 234 U/ 238 U as well as of the activities short-lived radionuclides like 222 Rn, 224 Ra, 226 Ra, 228 Ra, 210 Po and 210 Pb have been performed. Their activities are controlled by chemical and physical parameters and depend also on the lithology of the source area. The combination of the three aspects provided relevant informations about the exchanges between the different water masses, about the transport mechanisms of the REE. Furthermore, the uranium series disequilibrium provided informations about the geochemical processes at a micro-scale. (author)

Final environmental statement on the transportation of radioactive material by air and other modes

International Nuclear Information System (INIS)

1977-12-01

An assessment is presented of the environmental impact from transportation of shipments of radioactive material into, within, and out of the United States. It is intended to serve as background material for a review by the United States Nuclear Regulatory Commission (NRC) of regulations dealing with transportation of radioactive materials. The impetus for such a review results not only from a general need to examine regulations to ensure their continuing consistency with the goal of limiting radiological impact to a level that is as low as reasonably achievable, but also from a need to respond to current national discussions of the safety and security aspects of nuclear fuel cycle materials. Chapters are included on regulations governing the transportation of radioactive materials, radiological effects, transport impact under normal conditions, impacts of transportation accidents, alternatives, and security and safeguards. A standard shipments model is also included along with a demographic model, excerpts from federal regulations, data on Pu, Population dose formulas, a list of radioactive material incidents, accident analysis methodology, and an analysis of risk assessment sensitivity

Felizia, Eduardo R.

2005-01-01

This report describes some of the regulatory and control functions legally conferred upon the Argentine Nuclear Regulatory Authority concerning radiological risks, as well as a critical analysis of the radiological risk acceptance criteria contained in the Argentine regulatory system. A summary of the application of regulatory standards AR 3.1.3. - 'Radiological criteria related to accidents in nuclear power reactors' and AR 4.1.3. - 'Radiological criteria related to accidents in research reactors' to concrete cases is made, while the favourable and unfavourable aspects of the risk acceptance criteria are discussed. The conclusion is that the Argentine regulatory system contains adequate radiological risk acceptance criteria, that the latter are consistent with the radiological protection principles applicable to man and that, for the moment, there is no need to perform any modifications that would broaden the conceptual framework on which such criteria are based.

The radioactive material is contained within the sealed source and the device allows the radiation to be used in a controlled way. Accidents can result if the control over a small fraction of those sources is lost. Sealed nuclear sources fall under the category of special form radioactive material, therefore they must meet safety requirements during transport according to regulations. Testing sealed radioactive sources is an important step in the conformity assessment process in order to obtain the design approval. In ICN Pitesti, the Reliability and Testing Laboratory is notified by CNCAN to perform tests on sealed radioactive sources. This paper wants to present aspects of the verifying tests on sealed capsules for Iridium-192 sources in order to demonstrate the compliance with the regulatory requirements and the program of quality assurance of the tests performed.

SOME ASPECTS REGARING CHLORINE DECAY IN WATER DISTRIBUTION NETWORKS

Directory of Open Access Journals (Sweden)

LIANA IOANA VUŢĂ

2011-03-01

Full Text Available A major objective of drinking water treatment is to provide microbiologically safe drinking water. The combination of conventional drinking water treatment and disinfection has proved to be one of the major public health advances in modern times. The quality of drinking water delivered to the customer’s tap is influenced by a number of processes; namely water treatment, disinfection and changes during transport of treated water via the distribution system. All natural waters and even treated drinking water exerts disinfectant demand due to the reactions with NOM and other constituents in water. Therefore, the applied disinfectant dose must be sufficient to meet the inherent demand in the treated water, to provide sufficient protection against microbial infection. Thus, controlling free residual chlorine properly is definitely important to ensure meeting regulatory requirements and satisfying customer needs.This paper presents the main aspects regarding chlorine decay in drinking-water distribution networks and, also a free chlorine decay simulation with EPANET2 on Ramnicu Valcea water distribution system.

Probability of spent fuel transportation accidents

International Nuclear Information System (INIS)

McClure, J.D.

1981-07-01

The transported volume of spent fuel, incident/accident experience and accident environment probabilities were reviewed in order to provide an estimate of spent fuel accident probabilities. In particular, the accident review assessed the accident experience for large casks of the type that could transport spent (irradiated) nuclear fuel. This review determined that since 1971, the beginning of official US Department of Transportation record keeping for accidents/incidents, there has been one spent fuel transportation accident. This information, coupled with estimated annual shipping volumes for spent fuel, indicated an estimated annual probability of a spent fuel transport accident of 5 x 10 -7 spent fuel accidents per mile. This is consistent with ordinary truck accident rates. A comparison of accident environments and regulatory test environments suggests that the probability of truck accidents exceeding regulatory test for impact is approximately 10 -9 /mile

Safety of transport of radioactive substances for civil use on the French territory. Lessons learned by the IRSN from the analysis of significant events reported in 2012 and 2013

International Nuclear Information System (INIS)

2014-01-01

The first part of this report proposes an overview of significant aspects and events related to the transport of radioactive substances in France, and a comment on lessons learned by the IRSN. The second and main part first presents some aspects of this specific transport: regulatory framework, main safety issues, nature and flow of these transports, transports of radioactive substances per sector. The second part proposes an analysis of significant events: elements related to the reporting of an event, assessment of events and analysis of main trends noticed in 2012 and 2013 with respect to previous years, analysis of the main types of events which occurred in 2013 and 2013 with respect with those which occurred during the previous years. The next chapter describes significant events: damage of a parcel during its handling, a non conformal content, loss of a parcel on a public road, derailment of a car in Le Bourget. Some transverse topics are finally addressed: return on experience of crisis management in relationship with events in radioactive substance transport, IRSN study on the behaviour of packaging during long duration fires

Visions of regulatory renewal

International Nuclear Information System (INIS)

Edgeworth, A.

1998-01-01

The economic contribution of the CEPA (Canadian Energy Pipeline Association) member companies to Canada's trade balance was discussed. CEPA member companies transport 95 per cent of the crude oil and natural gas produced in Canada to domestic and export markets. This represents a total of 5.6 Tcf of gas annually. Half of Canada's natural gas and oil production is exported to U.S. markets. All of these exports are transported by pipeline. CEPA member companies operate 90,000 km of pipeline from British Columbia to Quebec. Expansions are needed as a result of a significant increase in demand for natural gas and crude oil since 1990. Several issues exist for regulatory renewal. They include the need to create a level playing field, the overseeing of tolls and contract renewal terms, changing risk/reward trade-offs, the right to confidentiality of information and price discovery mechanism. The drivers for regulatory reform at Westcoast Energy are the need for pricing flexibility, customers desire for toll certainty, decontracting and opposition to rolled-in expansions for gathering and processing. An overview of Westcoast Energy's negotiated toll settlement, its implications, and the components of Westcoast Energy's 'light handed regulation' (LHR) was presented

The Dessau workshop on bioaccumulation: state of the art, challenges and regulatory implications.

Science.gov (United States)

Treu, Gabriele; Drost, Wiebke; Jöhncke, Ulrich; Rauert, Caren; Schlechtriem, Christian

2015-01-01

Bioaccumulation plays a vital role in understanding the fate of a substance in the environment and is key to the regulation of chemicals in several jurisdictions. The current assessment approaches commonly use the octanol-water partition coefficient (log K OW ) as an indicator for bioaccumulation and the bioconcentration factor (BCF) as a standard criterion to identify bioaccumulative substances show limitations. The log K OW does not take into account active transport phenomena or special structural properties (e.g., amphiphilic substances or dissociating substances) and therefore additional screening criteria are required. Regulatory BCF studies are so far restricted to fish and uptake through the gills. Studies on (terrestrial) air-breathing organisms are missing. Though there are alternative tests such as the dietary exposure bioaccumulation fish test described in the recently revised OECD test guideline 305, it still remains unclear how to deal with results of alternative tests in regulatory decision-making processes. A substantial number of bioaccumulation fish tests are required in regulation. The development of improved test systems following the 3R principles, namely to replace, reduce and refine animal testing, is thus required. All these aspects stress the importance to further develop the assessment of bioaccumulation. The Dessau Workshop on Bioaccumulation which was held from June 26th to 27th 2014, in Dessau, Germany, provided a comprehensive overview of the state of the art of bioaccumulation assessment, provided insights into the problems and challenges addressed by the regulatory authorities and described new research concepts and their regulatory implications. The event was organised by UBA (Dessau, Germany) and Fraunhofer IME (Schmallenberg, Germany). About 50 participants from industry, regulatory bodies and academia listened to 14 lectures on selected topics and joined the plenary discussions.

Regulatory status of burnup credit for dry storage and transport of spent nuclear fuel in the United States

International Nuclear Information System (INIS)

Carlson, D.E.

2001-01-01

During 1999, the Spent Fuel Project Office of the U.S. Nuclear Regulatory Commission (NRC) introduced technical guidance for allowing burnup credit in the criticality safety analysis of casks for transporting or storing spent fuel from pressurized water reactors. This paper presents the recommendations embodied by the current NRC guidance, discusses associated technical issues, and reviews information needs and industry priorities for expanding the scope and content of the guidance. Allowable analysis approaches for burnup credit must account for the fuel irradiation variables that affect spent fuel reactivity, including the axial and horizontal variation of burnup within fuel assemblies. Consistent with international transport regulations, the burnup of each fuel assembly must be verified by pre-loading measurements. The current guidance limits the credited burnup to no more than 40 GWd/MTU and the credited cooling time to five years, imposes a burnup offset for fuels with initial enrichments between 4 and 5 wt% 235U, does not include credit for fission products, and excludes burnup credit for damaged fuels and fuels that have used burnable absorbers. Burnup credit outside these limits may be considered when adequately supported by technical information beyond that reviewed to-date by the NRC staff. The guidance further recommends that residual subcritical margins from the neglect of fission products, and any other nuclides not credited in the licensing-basis analysis, be estimated for each cask design and compared against estimates of the maximum reactivity effects associated with remaining computational uncertainties and potentially nonconservative modeling assumptions. The NRC's Office of Nuclear Regulatory Research is conducting a research program to help develop the technical information needed for refining and expanding the evolving guidance. Cask vendors have announced plans to submit the first NRC license applications for burnup credit later this year

Polar transport in plants mediated by membrane transporters: focus on mechanisms of polar auxin transport.

Science.gov (United States)

Naramoto, Satoshi

2017-12-01

Directional cell-to-cell transport of functional molecules, called polar transport, enables plants to sense and respond to developmental and environmental signals. Transporters that localize to plasma membranes (PMs) in a polar manner are key components of these systems. PIN-FORMED (PIN) auxin efflux carriers, which are the most studied polar-localized PM proteins, are implicated in the polar transport of auxin that in turn regulates plant development and tropic growth. In this review, the regulatory mechanisms underlying polar localization of PINs, control of auxin efflux activity, and PIN abundance at PMs are considered. Up to date information on polar-localized nutrient transporters that regulate directional nutrient movement from soil into the root vasculature is also discussed. Copyright © 2017 Elsevier Ltd.

Orbital transport

International Nuclear Information System (INIS)

Oertel, H. Jr.; Koerner, H.

1993-01-01

The Third Aerospace Symposium in Braunschweig presented, for the first time, the possibility of bringing together the classical disciplines of aerospace engineering and the natural science disciplines of meteorology and air chemistry in a european setting. In this way, aspects of environmental impact on the atmosphere could be examined quantitatively. An essential finding of the european conference, is the unrestricted agreement of the experts that the given launch frequencies of the present orbital transport result in a negligible amount of pollutants being released in the atmosphere. The symposium does, however, call attention to the increasing need to consider the effect of orbital and atmospheric environmental impact of a future increase in launch frequencies of orbital transport in connection with future space stations. The Third Aerospace Symposium, 'Orbital Transport, Technical, Meteorological and Chemical Aspects', constituted a first forum of discussion for engineers and scientists. Questions of new orbital transport technologies and their environmental impact were to be discussed towards a first consensus. Through the 34 reports and articles, the general problems of space transportation and environmental protection were addressed, as well as particular aspects of high temperatures during reentry in the atmosphere of the earth, precision navigation of flight vehicles or flow behavior and air chemistry in the stratosphere.

Sugar and Glycerol Transport in Saccharomyces cerevisiae.

Science.gov (United States)

Bisson, Linda F; Fan, Qingwen; Walker, Gordon A

2016-01-01

In Saccharomyces cerevisiae the process of transport of sugar substrates into the cell comprises a complex network of transporters and interacting regulatory mechanisms. Members of the large family of hexose (HXT) transporters display uptake efficiencies consistent with their environmental expression and play physiological roles in addition to feeding the glycolytic pathway. Multiple glucose-inducing and glucose-independent mechanisms serve to regulate expression of the sugar transporters in yeast assuring that expression levels and transporter activity are coordinated with cellular metabolism and energy needs. The expression of sugar transport activity is modulated by other nutritional and environmental factors that may override glucose-generated signals. Transporter expression and activity is regulated transcriptionally, post-transcriptionally and post-translationally. Recent studies have expanded upon this suite of regulatory mechanisms to include transcriptional expression fine tuning mediated by antisense RNA and prion-based regulation of transcription. Much remains to be learned about cell biology from the continued analysis of this dynamic process of substrate acquisition.

Technological alternatives for plutonium transport

International Nuclear Information System (INIS)

1978-12-01

This paper considers alternative transport modes (air, sea, road, rail) for moving (1) plutonium from a reprocessing plant to a store or a fuel fabrication facility, and (2) MOX fuel from the latter to a reactor. These transport modes and differing forms of plutonium are considered in terms of: their proliferation resistance and safeguards; environmental and safety aspects; and economic aspects. It is tentatively proposed that the transport of plutonium could continue by air or sea where long distances are involved and by road or rail over shorter distances; this would be acceptable from the non-proliferation, environmental impact and economic aspects - there may be advantages in protection if plutonium is transported in the form of mixed oxide

Ontario hydro radioactive material transportation field guide

International Nuclear Information System (INIS)

Howe, W.

1987-01-01

The recent introduction of both the AECB Transport Packaging of Radioactive Material Regulations and Transport Canada's Transportation of Dangerous Goods Regulations have significantly altered the requirements for transporting radioactive material in Canada. Extensive additional training as well as certification of several hundred Ontario Hydro employees has been necessary to ensure compliance with the additional and revised regulatory requirements. To assist in the training of personnel, an 'active' corporate Ontario Hydro Field Guide for Radioactive Material Transport document has been developed and published. The contents of this Field Guide identify current Ontario Hydro equipment and procedures as well as the updated relevant regulatory requirements within Canada. In addition, to satisfying Ontario Hydro requirements for this type of information over two thousand of these Field Guides have been provided to key emergency response personnel throughout the province of Ontario to assist in their transportation accident response training

One consequence of zinc deficiency is an elevation in cell and tissue iron concentrations. To examine the mechanism(s) underlying this phenomenon, Swiss 3T3 cells were cultured in zinc-deficient (D, 0.5 microM zinc), zinc-supplemented (S, 50 microM zinc), or control (C, 4 microM zinc) media. After 24 h of culture, cells in the D group were characterized by a 50% decrease in intracellular zinc and a 35% increase in intracellular iron relative to cells in the S and C groups. The increase in cellular iron was associated with increased transferrin receptor 1 protein and mRNA levels and increased ferritin light chain expression. The divalent metal transporter 1(+)iron-responsive element isoform mRNA was decreased during zinc deficiency-induced iron accumulation. Examination of zinc-deficient cells revealed increased binding of iron regulatory protein 2 (IRP2) and decreased binding of IRP1 to a consensus iron-responsive element. The increased IRP2-binding activity in zinc-deficient cells coincided with an increased level of IRP2 protein. The accumulation of IRP2 protein was independent of zinc deficiency-induced intracellular nitric oxide production but was attenuated by the addition of the antioxidant N-acetylcysteine or ascorbate to the D medium. These data support the concept that zinc deficiency can result in alterations in iron transporter, storage, and regulatory proteins, which facilitate iron accumulation.

Federal and state regulatory schemes affecting liability for high-level waste transportation incidents: opportunities for clarification and amendment

International Nuclear Information System (INIS)

Friel, L.E.; Livingston-Behan, E.A.

1985-01-01

The Price-Anderson Act of 1957 provides extensive public liability coverage in the event of a serious accident involving the transportation of nuclear materials to or from certain federally-licensed, or federal contractor-operated facilities. While actual liability for a nuclear incident and the extent of damages are usually determined by state law, the Act establishes a comprehensive system for the payment of such damages. Despite the federally-mandated scheme for liability coverage several aspects of the Act's application to transportation to a permanent repository have not yet been settled and are open to various interpretations. Some areas of uncertainty apply not only to future waste transport to a repository, but also to current transportation activities, and include: coverage for emergency response and clean-up costs; coverage for precautionary evacuations; and the federal government's financial liability. The need to address liability issues is also increasingly recognized at the state level. The state laws which are used to determine liability and the extent of damages in the event of a transportation accident vary widely among states and significantly affect the compensation that an injured person will receive under the provisions of the Price-Anderson Act. Areas of state law deserving special attention include: standards for determining liability; statutes of limitations; standards for proof of causation; state sovereign immunity statutes; and recovery of unique emergency response costs

Toxic Volatile Organic Compounds (VOCs in the Atmospheric Environment: Regulatory Aspects and Monitoring in Japan and Korea

Directory of Open Access Journals (Sweden)

Wen-Tien Tsai

2016-09-01

Full Text Available In the past decades, hazardous air pollutants (HAPs, so-called air toxics or toxic air pollutants, have been detected in the atmospheric air at low concentration levels, causing public concern about the adverse effect of long-term exposure to HAPs on human health. Most HAPs belong to volatile organic compounds (VOCs. More seriously, most of them are known carcinogens or probably carcinogenic to humans. The objectives of this paper were to report the regulatory aspects and environmental monitoring management of toxic VOCs designated by Japan and Korea under the Air Pollution Control Act, and the Clean Air Conservation Act, respectively. It can be found that the environmental quality standards and environmental monitoring of priority VOCs (i.e., benzene, trichloroethylene, tetrachloroethylene, and dichloromethane have been set and taken by the state and local governments of Japan since the early 2000, but not completely established in Korea. On the other hand, the significant progress in reducing the emissions of some toxic VOCs, including acrylonitrile, benzene, 1,3-butadiene, 1,2-dichloroethane, dichloromethane, chloroform, tetrachloroethylene, and trichloroethylene in Japan was also described as a case study in the brief report paper.

Heat shock protein 70 inhibits shrinkage-induced programmed cell death via mechanisms independent of effects on cell volume-regulatory membrane transport proteins

DEFF Research Database (Denmark)

Nylandsted, J; Jäättelä, M; Hoffmann, E K

2004-01-01

Cell shrinkage is a ubiquitous feature of programmed cell death (PCD), but whether it is an obligatory signalling event in PCD is unclear. Heat shock protein 70 (Hsp70) potently counteracts PCD in many cells, by mechanisms that are incompletely understood. In the present investigation, we found...... that severe hypertonic stress greatly diminished the viability of murine fibrosarcoma cells (WEHI-902) and immortalized murine embryonic fibroblasts (iMEFs). This effect was attenuated markedly by Hsp70 over-expression. To determine whether the protective effect of Hsp70 was mediated via an effect on volume...... regulatory ion transport, we compared regulatory volume decrease (RVD) and increase (RVI) in control WEHI-902 cells and after increasing Hsp70 levels by heat shock or over-expression (WEHI-912). Hsp70 levels affected neither RVD, RVI nor the relative contributions of the Na(+)/H(+)-exchanger (NHE1) and Na...

The arabidopsis thaliana AGRAVITROPIC 1 gene encodes a component of the polar-auxin-transport efflux carrier

Chen, R.; Hilson, P.; Sedbrook, J.; Rosen, E.; Caspar, T.; Masson, P. H.

1998-01-01

Auxins are plant hormones that mediate many aspects of plant growth and development. In higher plants, auxins are polarly transported from sites of synthesis in the shoot apex to their sites of action in the basal regions of shoots and in roots. Polar auxin transport is an important aspect of auxin functions and is mediated by cellular influx and efflux carriers. Little is known about the molecular identity of its regulatory component, the efflux carrier [Estelle, M. (1996) Current Biol. 6, 1589-1591]. Here we show that mutations in the Arabidopsis thaliana AGRAVITROPIC 1 (AGR1) gene involved in root gravitropism confer increased root-growth sensitivity to auxin and decreased sensitivity to ethylene and an auxin transport inhibitor, and cause retention of exogenously added auxin in root tip cells. We used positional cloning to show that AGR1 encodes a putative transmembrane protein whose amino acid sequence shares homologies with bacterial transporters. When expressed in Saccharomyces cerevisiae, AGR1 promotes an increased efflux of radiolabeled IAA from the cells and confers increased resistance to fluoro-IAA, a toxic IAA-derived compound. AGR1 transcripts were localized to the root distal elongation zone, a region undergoing a curvature response upon gravistimulation. We have identified several AGR1-related genes in Arabidopsis, suggesting a global role of this gene family in the control of auxin-regulated growth and developmental processes.

Decina, Daniela; Fournier-Caruana, Jacqueline; Takane, Marina; Ostad Ali Dehaghi, Razieh; Sutter, Roland

2017-07-01

Withdrawal of type 2 oral poliovirus vaccine (OPV) in OPV-using countries required regulatory approval for use of inactivated poliovirus vaccine and bivalent OPV in routine immunization. Worldwide, a variety of mechanisms were used by member states, with some differences in approach observed between inactivated poliovirus vaccine and bivalent OPV. These included acceptance for use of World Health Organization (WHO) prequalified vaccines, registration and licensure pathways, participation in WHO-convened joint reviews of licensing dossiers, as well as pragmatic application of alternatively available mechanisms, when appropriate. Simple but effective tools were used to monitor progress and to record, authenticate, and share information. Essential to achievement of regulatory targets was ongoing communication with key stakeholders, including switch-country national regulatory authorities, vaccine manufacturers, partner organizations, and relevant units within WHO. Understanding of the regulatory environment gained through the OPV switch can be helpful in supporting further stages of the polio end game and other time-sensitive vaccine introduction programs. © The Author 2017.

Advances in citric acid fermentation by Aspergillus niger: biochemical aspects, membrane transport and modeling.

Science.gov (United States)

Papagianni, Maria

2007-01-01

Citric acid is regarded as a metabolite of energy metabolism, of which the concentration will rise to appreciable amounts only under conditions of substantive metabolic imbalances. Citric acid fermentation conditions were established during the 1930s and 1940s, when the effects of various medium components were evaluated. The biochemical mechanism by which Aspergillus niger accumulates citric acid has continued to attract interest even though its commercial production by fermentation has been established for decades. Although extensive basic biochemical research has been carried out with A. niger, the understanding of the events relevant for citric acid accumulation is not completely understood. This review is focused on citric acid fermentation by A. niger. Emphasis is given to aspects of fermentation biochemistry, membrane transport in A. niger and modeling of the production process.

Unsaturated flow and transport research questions and priorities

International Nuclear Information System (INIS)

Chery, D.L.

1993-01-01

A little over two years ago, a similar meeting (Workshop IV - Flow and Transport through Unsaturated Fractured Rock; Related to High-Level Radioactive Waste Disposal) was held her in Tucson, Arizona, to discuss the same issues discussed here the past 4 days. This presentation revisits what was said 2 years ago, reviews research needs that have been articulated by the licensing staff of the Division of High-Level Waste Management, Nuclear Regulatory Commission, and presents some of the thoughts on research needs resulting from the deliberations of a special committee of the National Research Council. After considering these aspects the questions of what has been accomplished in the past 2 years and where attention and energies should be focused in the coming few years, can be asked. 3 refs

Regulatory cross-cutting topics for fuel cycle facilities.

Energy Technology Data Exchange (ETDEWEB)

Denman, Matthew R.; Brown, Jason; Goldmann, Andrew Scott; Louie, David

2013-10-01

This report overviews crosscutting regulatory topics for nuclear fuel cycle facilities for use in the Fuel Cycle Research & Development Nuclear Fuel Cycle Evaluation and Screening study. In particular, the regulatory infrastructure and analysis capability is assessed for the following topical areas: Fire Regulations (i.e., how applicable are current Nuclear Regulatory Commission (NRC) and/or International Atomic Energy Agency (IAEA) fire regulations to advance fuel cycle facilities) Consequence Assessment (i.e., how applicable are current radionuclide transportation tools to support risk-informed regulations and Level 2 and/or 3 PRA) While not addressed in detail, the following regulatory topic is also discussed: Integrated Security, Safeguard and Safety Requirement (i.e., how applicable are current Nuclear Regulatory Commission (NRC) regulations to future fuel cycle facilities which will likely be required to balance the sometimes conflicting Material Accountability, Security, and Safety requirements.)

The utility industry's perspective on OCRWM's plans for developing the system for transporting spent fuel under the Nuclear Waste Policy Act

International Nuclear Information System (INIS)

Brodnick, D.A.

1988-01-01

The electric utility industry has a vital interest in the transport program to be developed by the Department of Energy's Office of Civilian Radioactive Waste Management under the Nuclear Waste Policy Act. The industry's interest stems in part from the fact that the DOE's transportation program is financed by the Nuclear Waste Fund which is made up of ratepayer funds. However, the industry is also vitally interested in the DOE's transportation program because it could impact the ongoing transportation operations of all nuclear utilities, and, perhaps most importantly, without the utility industry's input, DOE is not able to develop an optimal transportation program. The NWPA contemplates that the DOE conducts its transportation program in accordance with the existing federal and state regulatory structure. DOE has significant discretion, however, in creating and implementing the business, operational and institutional aspects of its NWPA transportation program. The utility industry intends to ensure that the DOE meets the challenge to develop a safe, efficient and economically sound program to transport spent fuel and high-level waste to the appropriate federal facilities

Contributions of the European Operating Experience Feedback Project to Support Regulatory Bodies

International Nuclear Information System (INIS)

Heitsch, M.

2016-01-01

Operating Experience Feedback (OEF) is one of the ways of improving the nuclear safety of operating nuclear power plants. The EC-Clearinghouse initiative was set up in 2008 to support nuclear regulatory authorities of EU Member States, but also Technical Support Organizations, international organizations and the broader nuclear community, to enhance nuclear safety. The differing regulatory regimes in the EU member countries and a significant diversity of the nuclear power plant (NPP) designs have been a challenge in the establishment of the European Clearinghouse. The European Clearinghouse is organized as a Network operated by a Central Office located at the Institute for Energy and Transport (IET) which is part of Joint Research Centre (JRC) of the European Commission. It gathers 17 European regulatory authorities and 3 major European Technical Support organizations (TSO). The Clearinghouse aims at providing lessons learned, recommendations and best practices from operational experience of NPPs based on support and commitment from the EU nuclear regulatory authorities. One of the objectives of the European Clearinghouse is to establish European best practices for the assessment of unusual events in NPPs. The paper will present the main activities of the European Clearinghouse. These include: • Topical studies providing in-depth assessment of selected topics important for the safe operation of NPPs. Statistical tools help to identify interesting subjects for these studies; • Quarterly reports on operating experience; • Training courses in the field of root cause analysis and event investigation; • Development, maintenance and population of a database for storage of operating experience related information; • Collaboration with international organizations such as IAEA and OECD/NEA on all aspects of OEF. All activities of the Clearinghouse initiative focus on providing an added value for nuclear regulation. (author)

Safety Culture Implementation in Indonesian Nuclear Energy Regulatory Agency (BAPETEN)

International Nuclear Information System (INIS)

Nurwidi Astuti, Y.H.; Dewanto, P.

2016-01-01

The Indonesia Nuclear Energy Act no. 10 of 1997 clearly stated that Nuclear Energy Regulatory Agency (BAPETEN) is the Nuclear Regulatory Body. This is the legal basis of BAPETEN to perform regulatory functions on the use of nuclear energy in Indonesia, including regulation, authorisation, inspection and enforcement. The Independent regulatory functions are stipulated in Article 4 and Article 14 of the Nuclear Energy Act no. 10 (1997) which require the government to establish regulatory body that is reporting directly to the president and has responsibility to control of the use of nuclear energy. BAPETEN has been start fully its functioning on January 4, 1999. In it roles as a regulatory body, the main aspect that continues and always to be developed is the safety culture. One of the objectives of regulatory functions is “to increase legal awareness of nuclear energy of the user to develop safety culture” (Article 15, point d), while in the elucidation of article 15 it is stipulated that “safety culture is that of characteristics and attitudes in organizations and individual that emphasise the importance of safety”.

Liability and insurance aspects of international transport of nuclear materials

International Nuclear Information System (INIS)

van Gijn, S.H.

1985-01-01

The Paris and Vienna Conventions do not affect the application of any international transport agreement already in force. However, in certain circumstances both the nuclear operator and the carrier may be held liable for nuclear damage which arises during international transports of nuclear materials. The ensuing cumulation of liabilities under the Nuclear and Transport Conventions may cause serious problems in obtaining adequate insurance cover for such transports. The 1971 Brussels Convention seeks to solve this problem by exonerating any person who might be held liable for nuclear damage under an international maritime convention or national law. Similar difficulties are encountered in the case of transports of nuclear materials between states which have and states which have not ratified the Paris and Vienna Conventions. (NEA) [fr

Regulatory authority infrastructure for Namibia

International Nuclear Information System (INIS)

Shangula, K.

2001-01-01

The Republic of Namibia is participating in the International Atomic Energy Agency's Model Project for the Improvement of National Regulatory Authority Infrastructures in Member States. The paper illustrates our experience in solving problems and difficulties confronted in establishing an effective regulatory authority operating within the existing national infrastructure that should be supported by the Government. An effective regulatory authority is seen as part of the wider administrative scope of our Government through ministerial mandates given by the State from time to time, guaranteeing its independence when implementing legal provisions under statutes. Sections of the report illustrate our experience in the following areas: 1. National radiation protection policy 2. Structure of our national regulatory authority 3. Laws and regulations 4. Provisions for notification, authorization and registration 5. In-depth security measures for radiation sources and radioactive material 6. Systems for the inspection of radiation sources, radioactive materials, enforcement of legal provisions 7. Extent of the applications of radiation sources and radioactive materials in the country. The paper provides information regarding existing Government policy on radiation protection; structure and legal aspects of the national regulatory, including statutes and regulations; the extent of application and uses of radiation sources and security of radioactive materials; human resources: strengths and constraints; management practices and financing of regulatory authority; and plans for emergency recovery of orphan sources. National plans for management of disused sources, recovery of orphan sources, abnormal emergencies, communication of information to affected persons on exposure effects, and the safety training of persons using these applications are discussed. the paper provides a summary and some suggestions of the way forward for Namibia.

Regulatory capture by default: Offshore exploratory drilling for oil and gas

International Nuclear Information System (INIS)

Portman, Michelle E.

2014-01-01

This article examines a form of regulatory capture that occurs when significant ambiguity exists regarding the environmental protection standards for new types of activities in the marine environment. To begin with, there is little research that categorizes the typologies of regulatory capture despite the ubiquity of the phenomenon. After a discussion of theoretical approaches to regulatory capture, I describe the operative definition and theory appropriate to the situation related to authorization of oil and natural gas production in Israel following the discovery of large offshore reserves in 2010. This approach, embodying several facets of existing typologies, is applied to decisions made authorizing construction of the Gabriella offshore exploratory drilling platform. The analysis highlights the nature of capture in the absence of clear agency jurisdiction over new activities located in offshore environs organized as temporal and spatial “vacuums”. I conclude that comprehensive marine spatial planning would result in less capture and the development of more capture-resistant regulations. - Highlights: • Regulatory capture occurs when ambiguity exists about environmental protection standards for new types of activities in the marine environment. • A typology is developed from theories of regulatory capture (RC) and applied to cases of offshore exploratory drilling. • The typology is applied to offshore natural gas reserves discovered in 2010 offshore of Israel in the Mediterranean Sea. • Temporal aspects (anachronistic laws and regulations) and spatial aspects (jurisdictional ambiguity) have created regulatory vacuums leading to RC. • Comprehensive marine spatial planning would result in less capture and the development of more capture-resistant regulations

Regulatory reform in Mexico's natural gas sector

International Nuclear Information System (INIS)

1996-01-01

In recent years Mexico has implemented remarkable structural changes in its economy. However, until recently its large and key energy sector was largely unreformed. This is now changing. In 1995 the Mexican Government introduced legislative changes permitting private sector involvement in natural gas storage, transportation and distribution. Subsequent directives set up a detailed regulatory framework. These developments offer considerable promise, not only for natural gas sector development but also for growth in the closely linked electricity sector. This study analyses the changes which have taken place and the rationale for the regulatory framework which has been established. The study also contains recommendations to assist the Government of Mexico in effectively implementing its natural gas sector reforms and in maximizing the benefits to be realised through the new regulatory framework.

Regulatory agencies and regulatory risk

OpenAIRE

Knieps, Günter; Weiß, Hans-Jörg

2008-01-01

The aim of this paper is to show that regulatory risk is due to the discretionary behaviour of regulatory agencies, caused by a too extensive regulatory mandate provided by the legislator. The normative point of reference and a behavioural model of regulatory agencies based on the positive theory of regulation are presented. Regulatory risk with regard to the future behaviour of regulatory agencies is modelled as the consequence of the ex ante uncertainty about the relative influence of inter...

Review of decision methodologies for evaluating regulatory actions affecting public health and safety

International Nuclear Information System (INIS)

Hendrickson, P.L.; McDonald, C.L.; Schilling, A.H.

1976-12-01

This report examines several aspects of the problems and choices facing the governmental decision maker who must take regulatory actions with multiple decision objectives and attributes. Particular attention is given to the problems facing the U.S. Nuclear Regulatory Commission (NRC) and to the decision attribute of chief concern to NRC, the protection of human health and safety, with emphasis on nuclear power plants. The study was undertaken to provide background information for NRC to use in refining its process of value/impact assessment of proposed regulatory actions. The principal conclusion is that approaches to rationally consider the value and impact of proposed regulatory actions are available. These approaches can potentially improve the decision-making process and enable the agency to better explain and defend its decisions. They also permit consistent examination of the impacts, effects of uncertainty and sensitivity to various assumptions of the alternatives being considered. Finally, these approaches can help to assure that affected parties are heard and that technical information is used appropriately and to the extent possible. The principal aspects of the regulatory decision problem covered in the report are: the legal setting for regulatory decisions which affect human health and safety, elements of the decision-making process, conceptual approaches to decision making, current approaches to decision making in several Federal agencies, and the determination of acceptable risk levels

1979-01-01

The Large Aspect Ratio Tokamak Study (LARTS) investigated the potential for producing a viable long burn tokamak reactor through enhanced volt-second capability of the ohmic heating transformer by employing high aspect ratio designs. The plasma physics, engineering, and economic implications of high aspect ratio tokamaks were accessed in the context of extended burn operation. Plasma startup and burn parameters were addressed using a one-dimensional transport code. The pulsed electrical power requirements for the poloidal field system, which have a major impact on reactor economics, were minimized by optimizing the field in the ohmic heating coil and the wave shape of the ohmic heating discharge. A high aspect ratio reference reactor was chosen and configured

Regulatory aspects of oncology drug safety evaluation: Past practice, current issues, and the challenge of new drugs

International Nuclear Information System (INIS)

Rosenfeldt, Hans; Kropp, Timothy; Benson, Kimberly; Ricci, M. Stacey; McGuinn, W. David; Verbois, S. Leigh

2010-01-01

The drug development of new anti-cancer agents is streamlined in response to the urgency of bringing effective drugs to market for patients with limited life expectancy. FDA's regulation of oncology drugs has evolved from the practices set forth in Arnold Lehman's seminal work published in the 1950s through the current drafting of a new International Conference on Harmonization of Technical Requirements for Registration of Pharmaceuticals for Human Use (ICH) safety guidance for anti-cancer drug nonclinical evaluations. The ICH combines the efforts of the regulatory authorities of Europe, Japan, and the United States and the pharmaceutical industry from these three regions to streamline the scientific and technical aspects of drug development. The recent development of new oncology drug classes with novel mechanisms of action has improved survival rates for some cancers but also brings new challenges for safety evaluation. Here we present the legacy of Lehman and colleagues in the context of past and present oncology drug development practices and focus on some of the current issues at the center of an evolving harmonization process that will generate a new safety guidance for oncology drugs, ICH S9. The purpose of this new guidance will be to facilitate oncology drug development on a global scale by standardizing regional safety requirements.

Omniclassical Diffusion in Low Aspect Ratio Tokamaks

International Nuclear Information System (INIS)

Mynick, H.E.; White, R.B.; Gates, D.A.

2004-01-01

Recently reported numerical results for axisymmetric devices with low aspect ratio A found radial transport enhanced over the expected neoclassical value by a factor of 2 to 3. In this paper, we provide an explanation for this enhancement. Transport theory in toroidal devices usually assumes large A, and that the ratio B p /B t of the poloidal to the toroidal magnetic field is small. These assumptions result in transport which, in the low collision limit, is dominated by banana orbits, giving the largest collisionless excursion of a particle from an initial flux surface. However in a small aspect ratio device one may have B p /B t ∼ 1, and the gyroradius may be larger than the banana excursion. Here, we develop an approximate analytic transport theory valid for devices with arbitrary A. For low A, we find that the enhanced transport, referred to as omniclassical, is a combination of neoclassical and properly generalized classical effects, which become dominant in the low-A, B p /B t ∼ 1 regime. Good agreement of the analytic theory with numerical simulations is obtained

The future of the transport regulations

International Nuclear Information System (INIS)

Boyle, R.W.

2004-01-01

In September, 2000 the IAEA formally began a two year, continuing regulatory review process. To no one's surprise, the initial review process has evolved and corrections and improvements have been implemented with each successive cycle. To the credit of both the agency and the participants from Member States and industry, the first cycles have created a viable and stable review process which is more efficient and far simpler than the previous review process. Unfortunately, problems still exist in the transport community. It is my opinion that these issues have little to do with review process and more to do with program management and the culture of the community. I believe it is time for IAEA transport division (IAEA) and the Transport Safety Series Committee (TRANSSC) to recognize the transport program is more than just a regulatory development program and begin to face the difficult issues in front of them. Toward that end, this paper will identify the five largest issues facing the radioactive material transport industry and recommend how the IAEA, TRANSSC, Member States, industry and the general public can address these issues

Fostering member state implementation of the IAEA's transport regulations

International Nuclear Information System (INIS)

Brittinger, M.T.M.; Wangler, M.E.

2004-01-01

Based on a 1959 mandate from the United Nations Economic and Social Council, international safety requirements are embodied in the ''Regulations for the Safe Transport of Radioactive Material'' that were first published by the International Atomic Energy Agency in 1961 and revised in 1967, 1973, 1985 and 1996 to keep them abreast of scientific and technical developments. The requirements are incorporated into the regulatory documents of the International Civil Aviation Organization for air transport, and the International Maritime Organization for marine transport. As the requirements of the latter documents are legally-binding for the member states of the corresponding organizations, the IAEA safety requirements thus also become mandatory in those countries. The same situation applies for the surface modes in Europe, by means of the regulatory documents of the European Community for rail, road and inland waterways. Nevertheless, the IAEA has not relaxed its efforts to ensure that its Transport Regulations stay abreast of scientific and technical developments; on the contrary, it has been undertaking a regular and vigorous review of its safety requirements, and continues to do so with the assistance of Member States and relevant international organizations. Beyond providing the regulatory basis for the safe transport of radioactive material, however, the IAEA also offers a work programme under which it assists Member States in complying with the regulatory requirements. This assistance comes in the form of providing training on the safety requirements, and publishing documents that facilitate the exchange of information

The plasma physics, engineering, and economic implications of high aspect ratio tokamaks were assessed in the context of extended burn operation. Using a one-dimensional transport code plasma startup and burn parameters were addressed. The pulsed electrical power requirements for the poloidal field system, which have a major impact on reactor economics, were minimized by optimizing the startup and shutdown portions of the tokamak cycle. A representative large aspect ratio tokamak with an aspect ratio of 8 was found to achieve a burn time of 3.5 h at capital cost only approx. 25% greater than that of a moderate aspect ratio design tokamak

Radiation and the regulatory landscape of neo2-Darwinism

International Nuclear Information System (INIS)

Rollo, C. David

2006-01-01

Several recently revealed features of eukaryotic genomes were not predicted by earlier evolutionary paradigms, including the relatively small number of genes, the very large amounts of non-functional code and its quarantine in heterochromatin, the remarkable conservation of many functionally important genes across relatively enormous phylogenetic distances, and the prevalence of extra-genomic information associated with chromatin structure and histone proteins. All of these emphasize a paramount role for regulatory evolution, which is further reinforced by recent perspectives highlighting even higher-order regulation governing epigenetics and development (EVO-DEVO). Modern neo 2 -Darwinism, with its emphasis on regulatory mechanisms and regulatory evolution provides new vision for understanding radiation biology, particularly because free radicals and redox states are central to many regulatory mechanisms and free radicals generated by radiation mimic and amplify endogenous signalling. This paper explores some of these aspects and their implications for low-dose radiation biology

Regulatory perspectives of concept assessment

Flavelle, Peter A.

1987-09-01

The Atomic Energy Control Board is the head agency for the regulatory review of the Assessment of the Canadian Concept for Nuclear Fuel Waste Disposal being done by Atomic Energy of Canada Limited and Ontario Hydro. This paper describes the regulatory perspective of how the Concept Assessment could demonstrate the feasibility of a disposal conforming to regulatory requirements. The long-term aspects of Concept Assessment encourage the use of various predictive techniques for different time scales. Each technique will have a different potential for establishing confidence in the predictions. The predicted performance of a facility during operation should have a very high confidence, as it can be based on standard engineering calculations and the predictions can be validated later by monitoring during operation. The predictions of the transient period following closure of the facility should achieve a medium level of confidence, since they can be based on extrapolations of predictions of operational performance, using models that can be calibrated with monitoring data and with averaged input data derived from natural analog studies. Predictions based on fundamental processes will have a medium level of confidence when made to intermediate times after closure. Long-term predictions using generic or typical input data or Monte Carlo calculations of simplified models will have the least confidence and yet they can still contribute to the confidence that the disposal concept will conform to regulatory requirements

Flory, Egbert; Reinhardt, Jens

2013-12-01

Increasing scientific knowledge and technical innovations in the areas of cell biology, biotechnology and medicine resulted in the development of promising therapeutic approaches for the prevention and treatment of human diseases. Advanced therapy medicinal products (ATMPs) reflect a complex and innovative class of biopharmaceuticals as these products are highly research-driven, characterised by innovative manufacturing processes and heterogeneous with regard to their origin, type and complexity. This class of ATMP integrates gene therapy medicinal products, somatic cell therapy medicinal products and tissue engineering products and are often individualized and patient-specific products. Multiple challenges arise from the nature of ATMPs, which are often developed by micro, small and medium sized enterprises, university and academia, for whom regulatory experiences are limited and regulatory requirements are challenging. Regulatory guidance such as the reflection paper on classification of ATMPs and guidelines highlighting product-specific issues support academic research groups and pharmaceutical companies to foster the development of safe and effective ATMPs. This review provides an overview on the European regulatory aspects of ATMPs and highlights specific regulatory tools such as the ATMP classification procedure, a discussion on the hospital exemption for selected ATMPs as well as borderline issues towards transplants/transfusion products.

Perceptions, perspectives, proportions: Radioactive material transport

International Nuclear Information System (INIS)

1985-01-01

Nearly a hundred years ago in 1893 - when railroads still monopolized land transport, the first set of international rules governing shipments of hazardous materials were issued to cover their movement by rail. Since then, more than a dozen international bodies, and scores of national regulatory agencies, have published regulations directed at the carriage of dangerous goods by road, sea, air, as well as rail. The regulatory network today covers virtually all kinds of substances and commodities that are used for beneficial purposes, but that under certain conditions are potentially harmful to people and the environment. 'The Problems Encountered by International Road Transport in Multimodal Transport Operations', by M. Marmy, paper presented at the 8th International Symposium on the Transport and Handling of Dangerous Goods by Sea and Associated Modes, Havana, Cuba, 1984. These include the chemical fertilizers farmers spread on their fields, the nuclear fuel now powering electricity plants in some two dozen countries, the drugs physicians use to diagnose and treat illnesses, and the fossil fuels, such as gasoline, routinely used in transport vehicles. All told today, about 21 different international labels are required to identify separate classes of dangerous goods among them, explosives, corrosives, and flammables. Another separate class radioactive materials is the specific subject of feature articles in this issue of the IAEA Bulletin. The evolving regulatory system reflects at once the growth in traffic of hazardous materials, essentially a post-World War II trend. Since the mid-1940s, for example, the transport of all dangerous goods just on the seas has grown 1000%. based on reports at a recent international conference. Overall, years ahead will see further increases

The results of the experiment and theory from low-aspect ratio tokamak devices have proved that the MHD stability will be improved. Based on present plasma physics and extrapolation to reduced aspect ratio, the feature of physics of low-aspect ratio tokamak reactor is discussed primarily. Alpha particle confinement and loss in the self-justified low-aspect ratio tokamak reactor parameters and the effect of alpha particle confinement and loss for different aspect ratio are calculated. The results provide a reference for the feasible research of compact tokamak reactor. (9 refs., 2 figs., 3 tabs.)

BCS based biowaivers are recognized by major regulatory agencies. An application for a biowaiver can be supported by or even based on "in vitro" measurements of drug permeability. However, guidelines limit the application of biowaivers to drug substances that are transported only by passive mechanisms. Regarding published permeability data as well as measurements obtained in our institution, one can rarely observe drug substances that conform to this very strict criterion. Therefore, we measured the apparent permeability coefficients of 13 drugs recommended by FDA's Guidance to be used as standards for "in vitro" permeability classification. The asymmetry of permeability data determined for both directions (mucosal-to-serosal and serosalto- mucosal) through the rat small intestine revealed significant active transport for four out of the nine high-permeability standards and for all four low-permeability standard drugs. As could be expected, this asymmetry was abolished at 4°C on rat intestine. The permeability of all nine high-permeability, but none of the low permeability standards, was also much lower when measured with intestinal tissue, Caco-2 cell monolayers or artificial membranes at 4°C compared to standard conditions (37°C). Additionally, concurrent testing of several standard drugs revealed that membrane transport can be affected by the use of internal permeability standards. The implications of the results are discussed regarding the regulatory aspects of biopharmaceutical classification, good practice in drug permeability evaluation and regarding the general relevance of transport proteins with broad specificity in drug absorption.

Comfortable mobile offices: A literature review of the ergonomic aspects of mobile device use in transportation settings.

Kamp, I; Van Veen, S A T; Vink, P

2015-01-01

The use of mobile devices as an addition to or replacement of desktop computers for traditional office work results in more flexibility of workplaces. Consequently transportation time is used for office work and this asks for comfortable mobile offices. The aim of this review is providing a framework of the relevant elements for comfortable mobile offices and defining needs for future research. This literature review draws on 68 papers, theses, reviews and critiques. The framework is based on existing literature on traditional office ergonomics and comfort literature for different transportation modes like trains, buses, airplanes and cars. The main differences with traditional offices are the type of devices, dynamic versus static situation, the sole use of mobile devices and therefore the need for a good arm support to avoid an uncomfortable neck flexion, limited space, and the presence of strangers which influence the privacy perception. Important topics for future research are: the effect on the employee and the environment of the ability and demand of working anywhere, and the requirements for the physical aspects of mobile offices.

Current trends in nuclear material transportation

Ravenscroft, Norman; Oshinowo, Franchone

1997-01-01

The business of radioactive material transportation has evolved considerably in the past 40 years. Current practices reflect extensive international experience in handling radioactive cargo within a mature and tested regulatory framework. Nevertheless, new developments continue to have an impact on how shipments of nuclear material are planned and carried out. Entities involved in the transport of radioactive materials must keep abreast of these developments and work together to find innovative solutions to ensure that safe, smooth transport activities may continue. Several recent trends in the regulatory environment and political atmosphere require attention. There are four key trends that we'll be examining today: 1) the reduction in the pool of available commercial carriers; 2) routing restrictions; 3) package validation issues; and 4) increasing political sensitivities. Careful planning and cooperative measures are necessary to alleviate problems in each of these areas. (author)

International transport of incandescent gas mantles - an incident

International Nuclear Information System (INIS)

Singh, Khaidem R.K.

2004-01-01

Consumer products, though contain small quantities of radioactive material, are designed and manufactured with reference to prescribed safety standards; and supplied for use in public domain. On the basis of the nature of the exposures associated with such practices, which are quite low, the Regulatory Authority exempts the practices from many of the regulatory requirements. As they are inherently safe for handling, transporting and use, they are exempted from some of the requirements under the provisions of the regulations on the transport of radioactive material. Though the basic meaning and purpose of a radioactivity-based consumer product are similar to other commodities, there is a need to transport the former as per the regulations for safe transport of radioactive material till the product reaches at end user. The strict adherence to the transport regulations during transport of the radioactivity-based consumer product would ensure smooth carriage particularly in international arena. On the basis of an incident that happened during the transport of consumer products, this paper analyzes the provisions relating to radioactivity-based consumer products as envisaged in the basic safety standards of IAEA and their transport, particularly for natural thorium based consumer product gas mantles.

The Iranian Nuclear Regulatory Authority (INRA) has been addressed the actions to be taken in respect of the safe and secure transport of radioactive material. Firstly, INRA translated TS-R-1 and approved it as national standard and imparted it to all entities that engage in transport of radioactive material. Training course was provided for the designers, consignors, carriers and consignees based on their actions in transport of radioactive material. All radioactive material carrier companies were enforced to observe all aspects of national standard and receive an authorized license of National Radiation Protection Department (NRPD). The NRPD has written procedures to regain control of the radiation sources together with the National Waste Management Department. Transport arrangements are in place for imported and exported sources. According to the Code of Conduct on safety and security, the sources category I, II and III have been registered in data bases carefully so far. All the licensees are obligated to inform the Regulatory Authority for any changes in position, application, possession, transfer or waste of radiation sources. There is a formal agreement with the National Security Council to permit the import of scrap metal at major entry points on the borders. Scrap metal importers are required to use these points of entry which are monitored by officers of the NRPD and portal gate monitors which are installed at the main entry points and be controlled from unique centre. If required, the NRPD will supply staff to other border entry points. Presently some portal gate monitors are in progress at the borderline customs also. All the major metal recycling facilities in IRAN have installed portal gate monitors to recheck their scrap metal imports. (author)

Regulatory policies in many parts of the world recognize either the utility of or the mandate that all available studies be considered in environmental or ecological hazard and risk assessment (ERA) of chemicals, including studies from the peer-reviewed literature. Consequently, a vast array of different studies and data types need to be considered. The first steps in the evaluation process involve determining whether the study is relevant to the ERA and sufficiently reliable. Relevance evaluation is typically performed using existing guidance but involves application of "expert judgment" by risk assessors. In the present paper, we review published guidance for relevance evaluation and, on the basis of the practical experience within the group of authors, we identify additional aspects and further develop already proposed aspects that should be considered when conducting a relevance assessment for ecotoxicological studies. From a regulatory point of view, the overarching key aspect of relevance concerns the ability to directly or indirectly use the study in ERA with the purpose of addressing specific protection goals and ultimately regulatory decision making. Because ERA schemes are based on the appropriate linking of exposure and effect estimates, important features of ecotoxicological studies relate to exposure relevance and biological relevance. Exposure relevance addresses the representativeness of the test substance, environmental exposure media, and exposure regime. Biological relevance deals with the environmental significance of the test organism and the endpoints selected, the ecological realism of the test conditions simulated in the study, as well as a mechanistic link of treatment-related effects for endpoints to the protection goal identified in the ERA. In addition, uncertainties associated with relevance should be considered in the assessment. A systematic and transparent assessment of relevance is needed for regulatory decision making. The relevance

The advent of new testing systems and "omics"-technologies has left regulatory toxicology facing one of the biggest challenges for decades. That is the question whether and how these methods can be used for regulatory purposes. The new methods undoubtedly enable regulators to address important open questions of toxicology such as species-specific toxicity, mixture toxicity, low-dose effects, endocrine effects or nanotoxicology, while promising faster and more efficient toxicity testing with the use of less animals. Consequently, the respective assays, methods and testing strategies are subject of several research programs worldwide. On the other hand, the practical application of such tests for regulatory purposes is a matter of ongoing debate. This document summarizes key aspects of this debate in the light of the European "regulatory status quo", while elucidating new perspectives for regulatory toxicity testing.

Logistics aspects of pipeline transport in the supply of petroleum products

Directory of Open Access Journals (Sweden)

Wessel Pienaar

2008-09-01

Full Text Available The commercial transportation of crude oil and petroleum products by pipeline is receiving increased attention in South Africa. Transnet Pipeline Transport has recently obtained permission from the National Energy Regulator of South Africa (Nersa to construct and operate a new petroleum products pipeline of 60 cm diameter from Durban to Gauteng. At an operating speed of 10 km/h the proposed 60 cm Transnet pipeline would be able to deliver 3,54 million litres of petroleum product per hour. This is equivalent to 89 deliveries per hour using road tank vehicles with an average carrying capacity of 40 000 litres of fuel per vehicle. This pipeline throughput is also equivalent to two trains departing per hour, each consisting of 42 petroleum tank wagons with an average carrying capacity of 42 500 litres of fuel per wagon. Considering that such road trucks and rail wagons return empty to the upstream refineries in Durban, it is clear that there is no tenable long-term alternative to pipeline transport:pipeline transport is substantially cheaper than road and rail transport;pipeline transport is much safer than rail and especially road transport; andpipeline transport frees up alternative road and rail transport capacity.Pipeline transport is a non-containerised bulk mode of transport for the carriage of suitable liquids (for example, petroleum commodities, which include crude oil, refined fuel products and liquid petro-chemicals, gas, slurrified coal and certain water-suspended ores and minerals. InSouth Africa, petroleum products account for the majority of commercial pipeline traffic, followed by crude oil and natural gas. There are three basic types of petroleum pipeline transport systems:Gathering pipeline systemsCrude oil trunk pipeline systemsRefined products pipeline systems Collectively, these systems provide a continuous link between extraction, processing, distribution, and wholesalers’ depots in areas of consumption.

Canada's regulatory framework: The Canadian Nuclear Safety Commission's regulatory framework

International Nuclear Information System (INIS)

Howard, D.

2011-01-01

This paper will discuss the Canadian Nuclear Safety Commission and Canada's Regulatory Framework with respect to Low- and Intermediate-Level Radioactive Waste. The management of low and intermediate level radioactive waste must be ensured in a consistent, environmentally responsible and economical manner throughout its lifecycle -- from its production to the final disposal option. Radioactive waste has been produced in Canada since the early 1930s when the first radium/uranium mine began operating at Port Radium in the Northwest Territories. Pitchblende ore was transported from the Port Radium mine to Port Hope, Ontario where it was refined to produce radium for medical purposes. At present, radioactive waste is generated in Canada from the various stages and uses associated with the nuclear fuel cycle from uranium mining/milling to nuclear reactor operations to radioisotope manufacture and use. The Canadian Nuclear Safety Commission (CNSC regulates the use of nuclear energy and materials to protect the health, safety and security of Canadians and the environment; and to implement Canada's international commitments on the peaceful use of nuclear energy. The CNSC was established in 2000 under the Nuclear Safety and Control Act and reports to Parliament through the Minister of Natural Resources. The CNSC was created to replace the former Atomic Energy Control Board (AECB), which was founded in 1946. Under the Nuclear Safety and Control Act, CNSC's mandate involves four major areas: regulation of the development, production and use of nuclear energy in Canada to protect health, safety and the environment; regulation of the production, possession, use and transport of nuclear substances, and the production, possession and use of prescribed equipment and prescribed information; implementation of measures respecting international control of the development, production, transport and use of nuclear energy and substances, including measures respecting the

Integrated design for space transportation system

Little is known about the molecular and regulatory mechanisms of long-distance nitrate transport in higher plants. NRT1.5 is one of the 53 Arabidopsis thaliana nitrate transporter NRT1 (Peptide Transporter PTR) genes, of which two members, NRT1.1 (CHL1 for Chlorate resistant 1) and NRT1.2, have been shown to be involved in nitrate uptake. Functional analysis of cRNA-injected Xenopus laevis oocytes showed that NRT1.5 is a low-affinity, pH-dependent bidirectional nitrate transporter. Subcellular localization in plant protoplasts and in planta promoter-beta-glucuronidase analysis, as well as in situ hybridization, showed that NRT1.5 is located in the plasma membrane and is expressed in root pericycle cells close to the xylem. Knockdown or knockout mutations of NRT1.5 reduced the amount of nitrate transported from the root to the shoot, suggesting that NRT1.5 participates in root xylem loading of nitrate. However, root-to-shoot nitrate transport was not completely eliminated in the NRT1.5 knockout mutant, and reduction of NRT1.5 in the nrt1.1 background did not affect root-to-shoot nitrate transport. These data suggest that, in addition to that involving NRT1.5, another mechanism is responsible for xylem loading of nitrate. Further analyses of the nrt1.5 mutants revealed a regulatory loop between nitrate and potassium at the xylem transport step.

Introduction of generic medicinal products to the market has increased access to modern therapies but also enabled significant reduction in their cost, leading to containment of public expenditures on medicinal products reimbursement. The critical assessment of bioequivalence of any reference medicinal product and its counterpart is based on comparison of their rate and extent of absorption. It is assumed that two medicinal products are bioequivalent when their rate and extent of absorption do not show significant differences when administered at the same dose under similar experimental conditions. Bioequivalent medicinal products are declared to be also therapeutically equivalent and can be used interchangeably. However, despite regulatory declaration, switching from reference to generic drugs is often associated with concerns of healthcare providers about decreased treatment effectiveness or occurrence of adverse drug reactions. The aim of this article is to provide a description of rules that guide registration of generic medicinal products in the European Union and to analyze specific examples from the scientific literature concerning therapeutic equivalence of reference and generic antidepressant and antipsychotic medicinal products.

Several recently revealed features of eukaryotic genomes were not predicted by earlier evolutionary paradigms, including the relatively small number of genes, the very large amounts of non-functional code and its quarantine in heterochromatin, the remarkable conservation of many functionally important genes across relatively enormous phylogenetic distances, and the prevalence of extra-genomic information associated with chromatin structure and histone proteins. All of these emphasize a paramount role for regulatory evolution, which is further reinforced by recent perspectives highlighting even higher-order regulation governing epigenetics and development (EVO-DEVO). Modern neo{sup 2}-Darwinism, with its emphasis on regulatory mechanisms and regulatory evolution provides new vision for understanding radiation biology, particularly because free radicals and redox states are central to many regulatory mechanisms and free radicals generated by radiation mimic and amplify endogenous signalling. This paper explores some of these aspects and their implications for low-dose radiation biology.

Status on the regulatory aspects in NORM/TENORM activities and waste in Malaysia

International Nuclear Information System (INIS)

Hassan, Hasmadi

2005-01-01

In Malaysia, waste associated with TENORM are generated mostly in the tin mining and smelting, processing of minerals, and oil and gas industry. As one of a major tin producer in the world and the country current activities in oil production, the amount of waste generated in this kind of activities is quite substantial. Currently the government of Malaysia did not provide any provision in the law specifically for the exclusion of TENORM waste, however, the government did imposed the criteria for exclusion of this waste by adopting the guideline limit established by the IAEA safety series 26, which is very vital for the regulatory body i.e. Atomic Energy Licensing Board (AELB) to overcome the problems in managing some of waste related to TENORM industries. As one example, this guideline has been applied to one of the mineral processing industries in the country on decommissioning and disposing of their waste. Furthermore, due to economic reason and price of tin and its by-product is not viable and profitable so much, making this industry not significant in business and trade industries, several practices have been exempted from the regulatory control under the Atomic Energy Licensing Act, 1984.

Risk undermined in the bilateral pharmaceutical regulatory system in Taiwan.

Wang, Hui-Po; Wang, Chun-Li

2018-04-01

The concept of Pharmacovigilance Planning and Risk Minimization Planning (PVP/RMP), initiated by the International Conference on Harmonization (ICH), addressed an important conceptual change from monitoring the safety of individual medicine to proactively conducting risk prevention for the minimization of medication error. However, the implementation of PVP/RMP is a challenge in societies like Taiwan where irrational medication and co-medication is prevalent. It is even more difficult in Taiwan where two regulatory bodies are governing pharmaceutical affairs, namely Taiwan Food and Drug Administration (TFDA) in charge of Western Medicine (WM) and the Department of Chinese Medicine and Pharmacy (DCMP) in charge of Traditional Chinese Medicine (TCM). There are thus dual-tract drug approval panels, two GMP controls and two independent adverse drug event reporting systems. This rendered irrational co-medication of WM and TCM undetectable and the standard tools for monitoring pharmacovigilance inapplicable. The bilateral regulatory system is conceptually unscientific in accordance with PVP/RMP and unethical from humanity point of view. The first part of this review delivers (1) social aspects of polypharmacy in Taiwan; (2) regulatory aspects of pharmaceutical administration; (3) risks undermined in the bilateral regulatory system and (4) pharmacoepidemiology in relation to the risk of polypharmacy. As evidence-based medicine (EBM) forms the fundamental risk-benefit assessment on medication, the second part of this review delivers (1) the scientific aspects of the beauty and the odds of biological system that governs host-xenobiotics interaction; (2) conceptual evolution from product management (pharmacovigilance) to risk management (PVP/RMP); (3) non-biased due process is essential for risk-benefit assessment on medicinal products and (4) the opinion of the authors on system building for safe medication.

On the Generation of Transport Suppression Barriers by Externally Driven Alfven Waves in D-Shaped, Low Aspect Ratio Tokamaks

International Nuclear Information System (INIS)

Bruma, C.; Cuperman, S.

2003-01-01

We investigate quantitatively the possibility of turbulence suppression through the generation of transport barriers in pre-heated low aspect ratio tokamaks (LARTs) by the sheared electric fields generated by externally driven rf waves in the frequency range ω A ≅ ci (ω A and ω ci are, respectively, Alfven and ion cyclotron frequencies). To this aim the following sequential steps are followed: (1) Solutions of the resistive two-fluid model full wave equation for a realistic LART configuration (D-shape cross-section and aspect ratio, R/a ∼> 1; as well as suitably located low field side, LFS, antenna) upon using a quite general dielectric tensor operator; (2) Calculation of the ponderomotive forces and their magnetic surface averages; (3) Solution of a strongly non-linear differential equation for the quasi-stationary radial electric field, including the particle orbit squeezing effects, based on the results of steps (1) and (2); and (4) Calculation of the radial flow shear, S perpend ; for both banana and potato collisional regimes

Regulatory mechanisms for iron transport across the blood-brain barrier.

Duck, Kari A; Simpson, Ian A; Connor, James R

2017-12-09

Many critical metabolic functions in the brain require adequate and timely delivery of iron. However, most studies when considering brain iron uptake have ignored the iron requirements of the endothelial cells that form the blood-brain barrier (BBB). Moreover, current models of BBB iron transport do not address regional regulation of brain iron uptake or how neurons, when adapting to metabolic demands, can acquire more iron. In this study, we demonstrate that both iron-poor transferrin (apo-Tf) and the iron chelator, deferoxamine, stimulate release of iron from iron-loaded endothelial cells in an in vitro BBB model. The role of the endosomal divalent metal transporter 1 (DMT1) in BBB iron acquisition and transport has been questioned. Here, we show that inhibition of DMT1 alters the transport of iron and Tf across the endothelial cells. These data support an endosome-mediated model of Tf-bound iron uptake into the brain and identifies mechanisms for local regional regulation of brain iron uptake. Moreover, our data provide an explanation for the disparity in the ratio of Tf to iron transport into the brain that has confounded the field. Copyright © 2017 Elsevier Inc. All rights reserved.

Regulatory Safety Requirements for Operating Nuclear Installations

International Nuclear Information System (INIS)

Gubela, W.

2017-01-01

The National Nuclear Regulator (NNR) is established in terms of the National Nuclear Regulator Act (Act No 47 of 1999) and its mandate and authority are conferred through sections 5 and 7 of this Act, setting out the NNR's objectives and functions, which include exercising regulatory control over siting, design, construction etc of nuclear installations through the granting of nuclear authorisations. The NNR's responsibilities embrace all those actions aimed at providing the public with confidence and assurance that the risks arising from the production of nuclear energy remain within acceptable safety limits -> Therefore: Set fundamental safety standards, conducting pro-active safety assessments, determining licence conditions and obtaining assurance of compliance. The promotional aspects of nuclear activities in South Africa are legislated by the Nuclear Energy Act (Act No 46 of 1999). The NNR approach to regulations of nuclear safety and security take into consideration, amongst others, the potential hazards associated with the facility or activity, safety related programmes, the importance of the authorisation holder's safety related processes as well as the need to exercise regulatory control over the technical aspects such as of the design and operation of a nuclear facility in ensuring nuclear safety and security. South Africa does not have national nuclear industry codes and standards. The NNR is therefore non-prescriptive as it comes to the use of industry codes and standards. Regulatory framework (current) provide for the protection of persons, property, and environment against nuclear damage, through Licensing Process: Safety standards; Safety assessment; Authorisation and conditions of authorisation; Public participation process; Compliance assurance; Enforcement

Regulatory Inspection of Nuclear Power Plants in NEA Member Countries

International Nuclear Information System (INIS)

1978-01-01

Based on the replies to a questionnaire, this report gives a description and comparative evaluation of the regulatory inspection activities in several NEA Member countries. The questionnaire which was circulated to all Member countries requested details on the organisation, system, scope and objectives of nuclear regulatory inspection and the effort required throughout all stages of the life of a nuclear plant including the use of independent bodies or consultants. Additional information was requested on the documentation concerned with regulatory inspections, incident and accident reporting procedures, and the duties, powers and bases for recruitment of regulatory personnel with the object of covering all related aspects. However, because of the differences in national practices and perhaps in the interpretation of the questionnaire, it proved to be extremely difficult to make an evaluation and comparison of inspection activities and effort involved in these Member countries. This report, which includes a section on the nuclear power programme in Member countries, should therefore only be regarded as an initial review but it provides a useful contribution to the exchange of experience and views on regulatory inspection practices

Final report, BWR drywell debris transport Phenomena Identification and Ranking Tables (PIRTs)

International Nuclear Information System (INIS)

Wilson, G.E.; Boyack, B.E.; Leonard, M.T.; Williams, K.A.; Wolf, L.T.

1997-09-01

The Nuclear Regulatory Commission has issued a Regulatory Bulletin and accompanying Regulatory Guide (1.82, Rev. 2) which requires licensees of boiling water reactors to develop a specific plan of action (including hardware backfits, if necessary) to preclude the possibility of early emergency core cooling system strainer blockage following a postulated loss-of-coolant-accident. The postulated mechanism for strainer blockage is destruction of piping insulation in the vicinity of the break and subsequent transport of fragmented insulation to the wetwell. In the absence of more definitive information, the Regulatory Guide recommends that licensees assume a drywell debris transport fraction of 1.0. Accordingly, the Nuclear Regulatory Commission initiated research focused toward developing a technical basis to provide insights useful to regulatory oversight of licensee submittals associated with resolution of the postulated strainer blockage issue. Part of this program was directed towards experimental and analytical research leading to a more realistic specification of the debris transport through the drywell to the wetwell. To help focus this development into a cost effective effort, a panel, with broad based knowledge and experience, was formed to address the relative importance of the various phenomena that can be expected in plant response to postulated accidents that may produce strainer blockage. The resulting phenomena identification and ranking tables reported herein were used to help guide research. The phenomena occurring in boiling water reactors drywells was the specific focus of the panel, although supporting experimental data and calculations of debris transport fractions were considered

Sustainability, natural and organic cosmetics: consumer, products, efficacy, toxicological and regulatory considerations

Directory of Open Access Journals (Sweden)

Bruno Fonseca-Santos

2015-03-01

Full Text Available The interest in sustainable products has increased along the years, since the choice of products, packaging and production processes have a great impact on the environment. These products are classified by regulatory agencies in different categories, aggregating advantages to the product and increasing the demand by consumers. However, there is no harmonization in guidelines of these certifying agencies and each cosmetic industry formulates their product and packaging in a more rational way, which causes less damage to the environment. Many cosmetic products have in their formulation natural products that perform a specific biological function, but these products should be evaluated on efficacy and toxicological aspects. The aim of this article is to approach sustainability, natural and organic cosmetics, considering the consumer and the efficacy, toxicological and regulatory aspects.

2013-01-01

The International Atomic Energy Agency (IAEA) is currently working on a recommendation in the form of guidelines for regulating consumer goods. Preparation of this document has a significant dimension of international issues, especially in terms of the application of the principles of justification and application of the concept of exemption. International harmonization among regulators ranging from the regional to the global level is a central issue and considering the complex issues that arise in addition to covering the scientific aspects also involve consideration of the legal aspects or values espoused by any State which may differ from one another. PERKA BAPETEN on consumer goods is still in the preparation stage so that the discussion of the material will be useful for improving the quality of the regulation in time. There is a significant gap of understanding to the related materials by the parties concerned (between local and international parties were among the local party). This paper intends to propose the understanding and views on radiation protection and regulatory control for consumer goods and hopely could contributed significantly to strengthening its regulatory control which is primarily through a reduction in the gap of understanding to the related concept that potentially multi perceptions and encourage stronger cooperation among regulatory bodies.

Regulatory aspects of underground disposal of radioactive waste in Switzerland

International Nuclear Information System (INIS)

Luethi, H.R.

1978-01-01

The management of radioactive waste has become an important problem in Switzerland, and work has now begun on technical investigations and the preparation of a regulatory framework for deep-underground disposal. The law currently in force is the Federal Law on the Peaceful Use of Atomic Energyy and Radiation Protection, under which two licences are required, one for construction and one for operation. An amendment to this Law is envisaged whereby the licensing system will be modified, in particular by requiring an additional licence which will be granted by the Federal Government, with the consent of Parliament, if the safe disposal of waste can be guaranteed. The producers of radioactive waste are primarily responsible for the management thereof, but the National Co-operative Society for the Storage of Radioactive Waste (NAGRA) has the task of planning, constructing and operating repositories. The licensing authority in Switzerland is the Federal department of Communications and Energy. (NEA) [fr

Fostering member state implementation of the IAEA's transport regulations

Energy Technology Data Exchange (ETDEWEB)

Brittinger, M.T.M.; Wangler, M.E. [International Atomic Energy Agency, Vienna (Austria)

2004-07-01

Based on a 1959 mandate from the United Nations Economic and Social Council, international safety requirements are embodied in the ''Regulations for the Safe Transport of Radioactive Material'' that were first published by the International Atomic Energy Agency in 1961 and revised in 1967, 1973, 1985 and 1996 to keep them abreast of scientific and technical developments. The requirements are incorporated into the regulatory documents of the International Civil Aviation Organization for air transport, and the International Maritime Organization for marine transport. As the requirements of the latter documents are legally-binding for the member states of the corresponding organizations, the IAEA safety requirements thus also become mandatory in those countries. The same situation applies for the surface modes in Europe, by means of the regulatory documents of the European Community for rail, road and inland waterways. Nevertheless, the IAEA has not relaxed its efforts to ensure that its Transport Regulations stay abreast of scientific and technical developments; on the contrary, it has been undertaking a regular and vigorous review of its safety requirements, and continues to do so with the assistance of Member States and relevant international organizations. Beyond providing the regulatory basis for the safe transport of radioactive material, however, the IAEA also offers a work programme under which it assists Member States in complying with the regulatory requirements. This assistance comes in the form of providing training on the safety requirements, and publishing documents that facilitate the exchange of information.

Regulatory aspects of radiation embrittlement of reactor vessel steels

International Nuclear Information System (INIS)

Randall, P.N.

1979-01-01

One purpose of this conference, is to re-examine the conventional wisdom about neutron radiation embrittlement and the methods used to counteract embrittlement in reactor vessels. Perhaps, there have been sufficient advances in fracture mechanics, core physics, dosimetry, and physical metallurgy to permit a forward step in the quantitative treatment of the subject. Certainly this would be consistent with the position of the U.S. Nuclear Regulatory Commission (the NRC) in general. ''There has been a continued evolution toward increased specificity.'' This statement appeared in the response prepared by the staff to a request from the Commission to explain how the staff decides to apply a new requirement and to whom, i.e., to back-fit or forward-fit-only or whatever. Pressure for increased specificity, i.e., for fleshing out general design criteria, comes from ''technical surprises'' in the form of operating experiences or from research information, and from attempts to improve our confidence in the safety of plants, especially new plants. Our goal is to have anticipated and evaluated all possible modes of failure with sufficient quantitativeness that the probability of failure can be estimated with some accuracy. Failing this, regulators demand large margins of safety to cover our ignorance

Environmental Aspects of Transport in the Context of Development of Inland Navigation

Directory of Open Access Journals (Sweden)

Galieriková Andrea

2016-09-01

Full Text Available Transport has an immense impact on the environment. The largest share of environmental pollution is caused by road transport. The atmosphere is threatened by fuel combustion of engines of road vehicles, thereby leading to the global warming of Earth. In addition to having an adverse impact on the environment, such as greenhouse gas emissions and carbon dioxide emissions, road transport also leads to external effects such as noise pollution, vibration, congestion and traffic accidents. The volume of transport in the world, notably on the roads, is increasing day by day. We should take the necessary steps to move to more environmentally-friendly modes of transportation, such as rail and inland navigation. Rail transportation is currently the largest competitor of road transport. If the waterways infrastructure is improved, there would be a decrease in the traffic flow of motorways and thus, we can move to a more environmentally-friendly transportation.

As noted elsewhere in this report, a central goal of the Extended Duration Orbiter Medical Project (EDOMP) was to ensure that cardiovascular and muscle function were adequate to perform an emergency egress after 16 days of spaceflight. The goals of the Regulatory Physiology component of the EDOMP were to identify and subsequently ameliorate those biochemical and nutritional factors that deplete physiological reserves or increase risk for disease, and to facilitate the development of effective muscle, exercise, and cardiovascular countermeasures. The component investigations designed to meet these goals focused on biochemical and physiological aspects of nutrition and metabolism, the risk of renal (kidney) stone formation, gastrointestinal function, and sleep in space. Investigations involved both ground-based protocols to validate proposed methods and flight studies to test those methods. Two hardware tests were also completed.

Amine-based Post Combustion Capture (PCC) of CO 2 is a readily available technology that can be deployed to reduce CO 2 emissions from coal fired power plants. However, PCC plants will likely release small quantities of amine and amine degradation products to the atmosphere along with the treated flue gas. The possible environmental effects of these emissions have been examined through different studies carried out around the world. Based on flue gas from a 400 MW ultra-supercritical coal fired power plant Aspen-Plus PCC process simulations were used to predict the potential atmospheric emissions from the plant. Different research initiatives carried out in this area have produced new knowledge that has significantly reduced the risk perception for the release of amine and amine degradation products to the atmosphere. In addition to the reduction of the CO 2 emissions, the PCC technology will also help in reducing SO x and NO 2 emissions. However, some other pollutants such as NH 3 and aerosols will increase if appropriate control technologies are not adopted. To study the atmospheric photo-oxidation of amines, attempts are being made to develop chemical reaction schemes that can be used for air quality assessment. However, more research is still required in this area to estimate the reactivity of amino solvents in the presence of other pollutants such as NO x and other volatile organic compounds in the background air. Current air quality guidelines may need to be updated to include limits for the additional pollutants such as NH 3 , nitrosamines and nitramines once more information related to their emissions is available. This paper focuses on describing the predicted concentrations of major pollutants that are expected to be released from a coal fired power plant obtained by ASPEN-Plus PCC process simulations in terms of current air quality regulations and other regulatory aspects.

Lxr-driven enterocyte lipid droplet formation delays transport of ingested lipids.

Science.gov (United States)

Cruz-Garcia, Lourdes; Schlegel, Amnon

2014-09-01

Liver X receptors (Lxrs) are master regulators of cholesterol catabolism, driving the elimination of cholesterol from the periphery to the lumen of the intestine. Development of pharmacological agents to activate Lxrs has been hindered by synthetic Lxr agonists' induction of hepatic lipogenesis and hypertriglyceridemia. Elucidating the function of Lxrs in regulating enterocyte lipid handling might identify novel aspects of lipid metabolism that are pharmacologically amenable. We took a genetic approach centered on the single Lxr gene nr1h3 in zebrafish to study the role of Lxr in enterocyte lipid metabolism. Loss of nr1h3 function causes anticipated gene regulatory changes and cholesterol intolerance, collectively reflecting high evolutionary conservation of zebrafish Lxra function. Intestinal nr1h3 activation delays transport of absorbed neutral lipids, with accumulation of neutral lipids in enterocyte cytoplasmic droplets. This delay in transport of ingested neutral lipids protects animals from hypercholesterolemia and hepatic steatosis induced by a high-fat diet. On a gene regulatory level, Lxra induces expression of acsl3a, which encodes acyl-CoA synthetase long-chain family member 3a, a lipid droplet-anchored protein that directs fatty acyl chains into lipids. Forced overexpression of acls3a in enterocytes delays, in part, the appearance of neutral lipids in the vasculature of zebrafish larvae. Activation of Lxr in the intestine cell-autonomously regulates the rate of delivery of absorbed lipids by inducting a temporary lipid intestinal droplet storage depot.

In the past four years, almost all nations and international or intergovernmental transport organizations have effected transitions from the 1967 to 1973 IAEA standards as their basis for regulatory requirements for the safe transport of radioactive materials. One major exception to this transition is the USA itself, where this transition has not yet taken place. Major amendments to revise 49 CFR Parts 100-199 of the Department of Transportation regulations and 10 CFR Part 71 of the Nuclear Regulatory Commission regulations are required to effect this transition. The notices of proposed rulemaking to effect this transition in the USA are expected to be published by DOT and NRC concurrently sometime in 1978. Final amendments can be expected later, after the public comment period on the notices and considerations of those comments. This paper summarizes the status of current thinking on US adoption of the 1973 IAEA standards, as well as the status of adoption of those standards by international intergovernmental organizations, such as the Intergovernmental Maritime Consultative Organization, International Civil Aviation Organization, etc. A number of the differences between the expected US regulations and other regulations based on the 1973 IAEA standards are explained. This paper also discusses a number of other events or matters which have been taking place in the US in the past four years which have or may have an effect on transport of nuclear materials and its regulation, including air transport of plutonium, rail transport of spent fuel and other regulations by state or political subdivisions. The paper also discusses changes to US regulations accomplished in the past four years, which are not related to 1973 IAEA standards, as well as some other possible areas where regulatory proposals might be anticipated, such as control of radiation exposures to certain transport workers and other matters

Since resuming the Foreign Research Reactor Spent Nuclear Fuel (FRR SNF) Acceptance Program in 1996, the Program has had to deal with difficult issues associated with the transportation of failed or damaged spent fuel. In several instances, problems with failed or damaged fuel have prevented the acceptance of the fuel at considerable cost to both the Department of Energy (DOE) and research reactor operators. In response to the problems faced by the Acceptance Program, DOE has undertaken significant steps to better define the spent fuel acceptance criteria. DOE has worked closely with the U.S. Nuclear Regulatory Commission to address failed or damaged research reactor spent fuel and to identify cask certificate issues which must be resolved by cask owners and foreign regulatory authorities. The specific issues associated with the transport of Materials Testing Reactor (MTR)-type FRR SNF will be discussed. The information presented will include U.S. Nuclear Regulatory Commission regulatory issues, cask certificate issues, technical constraints, and lessons learned. Specific information will also be provided on the latest efforts to revise DOE's Appendix B, Transport Package (Cask) Acceptance Criteria. The information presented in this paper will be important to foreign research reactor operators, shippers, and cask vendors, so that appropriate amendments to the Certificate of Compliance for spent fuel casks can be submitted in a timely manner to facilitate the safe and scheduled transport of FRR SNF

The transport of radioactive materials behaves to the equal that other chemical products, certain risks that its are necessary to know how to evaluate and to minimize, adopting all kinds of measures technician-administrative, with object of being able to guarantee that this risks stay in an acceptable level for the population potentially affected for the workers of the one sector and for the environment. To be able to evaluate the risk acceptable it is a difficult task, for that, national and international organizations have established a commitment to develop standards of radiological protection, to make every day but sure the transport of radioactive materials

A reappraisal of transport aircraft needs 1985 - 2000: Perceptions of airline management in a changing economic, regulatory, and technological environment

Spencer, F. A.

1982-01-01

Views of the executives of 24 major, national, regional, and commuter airlines concerning the effect of recent regulatory, economic, and technological changes on the roles they see for their airlines, and consequent changes in their plans for acquiring aircraft for the 1985 to 2000 period were surveyed. Differing perceptions on the economic justification for new-technology jets in the context of the carriers' present and projected financial conditions are outlined. After examining the cases for new or intermediate size jets, the study discusses turboprop powered transports, including the carriers' potential interest in an advanced technology, high-speed turboprop or prop-fan. Finally, the implications of foreign competition are examined in terms of each carrier's evaluation of the quality and financial offerings, as well as possible 'Buy American' policy predisposition.

Regulatory aspects of radiological hazards in mines and works

1987-01-01

The mining and processing of ores containing uranium and thorium can give rise to exposure to ionizing radiation via various pathways to both persons employed in mines and works and to members of the general public living in the vicinity of such facilities. Such exposures to radiation will not give rise to unacceptable levels of risk provided the source of such exposure are identified, quantified and controlled. In order to establish the necessary regulatory framework to ensure such identification, quantification and control, regulations are currently being promulgated under the Mines and Works Act to require that activities involving nuclear hazard material resulting from the mining and processing of materials containing uranium and thorium will be subject to such conditions that will ensure compliance with a system of radiation dose limitation laid down. It is proposed that conditions be established for each mine and works in the form of a Code of Practice specific to the facility, the provisions of which will be commensurate with the potential magnitude of the particular radiological hazards prevailing at that facility. Generic guidelines will be made available to enable suitable Codes of Practice to be drawn up. This paper discusses the various radiological hazards that may have to be considered, the scope and content of the generic guidelines and the dose limitation system with which it will be necessary to comply. 5 refs., 2 tabs

2002-01-01

Irradiation treatment of food is becoming an increasingly accepted processing option for countries in the Asia Pacific region wishing to meet growing sanitary and phytosanitary requirements in international trade. There remain however, large differences between the regulatory requirements in the countries in this region. This paper gives an outline on existing food irradiation regulations in the separate countries of the Asia Pacific region. New developments such as the recent decision by the Australia New Zealand Food Authority to start assessing applications for food irradiation treatment are discussed. Australia's intention to regulate the export of food treated by irradiation will also be outlined. Details of the decision to harmonise food irradiation regulations by 13 countries in the Asia Pacific region based on conformance with Codex requirements is outlined. The likelihood of other Asia Pacific countries enacting similar harmonisation of their regulations will be examined. Future development such as certification of irradiation as a sanitary treatment for food are discussed. The expected result of these initiatives is a likely increase in irradiated foods traded within the Asia Pacific region

We investigate quantitatively the possibility of turbulence suppression through the generation of transport barriers in pre-heated low aspect ratio tokamaks (LARTs) by the sheared electric fields generated by externally driven rf waves in the frequency range {omega}{sub A} {approx_equal} <{omega}{sub ci} ({omega}{sub A} and {omega}{sub ci} are, respectively, Alfven and ion cyclotron frequencies). To this aim the following sequential steps are followed: (1) Solutions of the resistive two-fluid model full wave equation for a realistic LART configuration (D-shape cross-section and aspect ratio, R/a {approx}> 1; as well as suitably located low field side, LFS, antenna) upon using a quite general dielectric tensor operator; (2) Calculation of the ponderomotive forces and their magnetic surface averages; (3) Solution of a strongly non-linear differential equation for the quasi-stationary radial electric field, including the particle orbit squeezing effects, based on the results of steps (1) and (2); and (4) Calculation of the radial flow shear, S{sub perpend}; for both banana and potato collisional regimes.

It has been found that microRNAs (miRNAs) can function as a regulatory factor across species. For example, food-derived plant miRNAs may pass through the gastrointestinal (GI) tract, enter into the plasma and serum of mammals, and interact with endogenous RNAs to regulate their expression. Although this new type of regulatory mechanism is not well understood, it provides a fresh look at the relationship between food consumption and physiology. To investigate this new type of mechanism, we conducted a systematic computational study to analyze the potential functions of these dietary miRNAs in the human body. In this paper, we predicted human and plant target genes using RNAhybrid and set some criteria to further filter them. Then we built the cross-species regulatory network according to the filtered targets, extracted central nodes by PageRank algorithm and built core modules. We summarized the functions of these modules to three major categories: ion transport, metabolic process and stress response, and especially some target genes are highly related to ion transport, polysaccharides and the lipid metabolic process. Through functional analysis, we found that human and plants have similar functions such as ion transport and stress response, so our study also indicates the existence of a close link between exogenous plant miRNA targets and digestive/urinary organs. According to our analysis results, we suggest that the ingestion of these plant miRNAs may have a functional impact on consuming organisms in a cross-kingdom way, and the dietary habit may affect the physiological condition at a genetic level. Our findings may be useful for discovering cross-species regulatory mechanism in further study.

The IAEA Office of Nuclear Security is working cooperatively with the U.S. Department of Energy's Global Threat Reduction Initiative, European Union and Australia to provide transport security assistance to countries throughout the world. Assistance is available to countries in reviewing and upgrading their transport security programs at all levels: (1) National level (regulatory and other government agencies); and (2) Operator level (shippers and carriers). Assistance is directed at implementing a consistent level of security throughout the life cycle of radioactive material (same level of security during transport as when in a fixed facility) Upgrade assistance can include: (1) Expert advisory missions to provide advice and guidance; (2) Training courses for regulatory, governmental and industry personnel; (3) Transport security awareness; (4) Detailed training on designing and implementing transport security programs; (5) Planning to identify and prioritize needs (developing security approaches and plans); (6) Developing model security plans and procedures; and (7) Equipment (vehicles, packages, command and control equipment, etc.). Country visits are now being scheduled to initiate transport security cooperative activities. A training course has been developed to assist countries in developing and implementing transport security programs. The training course has been given as a national training course (three times) and as a Regional training course (three times). The course addresses recommended security provisions for the transport of all radioactive material.

Rapid transporter regulation prevents substrate flow traffic jams in boron transport

Science.gov (United States)

Sotta, Naoyuki; Duncan, Susan; Tanaka, Mayuki; Sato, Takafumi

2017-01-01

Nutrient uptake by roots often involves substrate-dependent regulated nutrient transporters. For robust uptake, the system requires a regulatory circuit within cells and a collective, coordinated behaviour across the tissue. A paradigm for such systems is boron uptake, known for its directional transport and homeostasis, as boron is essential for plant growth but toxic at high concentrations. In Arabidopsis thaliana, boron uptake occurs via diffusion facilitators (NIPs) and exporters (BORs), each presenting distinct polarity. Intriguingly, although boron soil concentrations are homogenous and stable, both transporters manifest strikingly swift boron-dependent regulation. Through mathematical modelling, we demonstrate that slower regulation of these transporters leads to physiologically detrimental oscillatory behaviour. Cells become periodically exposed to potentially cytotoxic boron levels, and nutrient throughput to the xylem becomes hampered. We conclude that, while maintaining homeostasis, swift transporter regulation within a polarised tissue context is critical to prevent intrinsic traffic-jam like behaviour of nutrient flow.

The industry commitment to global transport safety standards

Standards and regulations have no intrinsic practical effect without taking into account those who are the object of such standards and regulations. Standards and regulations do not become operationally effective until they are implemented by the entities which are subject to them. Accordingly, there is a necessary synergy between the regulator and the regulated - the regulators whose task it is to make and enforce the rules for safe, efficient and reliable transport, and those whose job it is to transport within the rules. One has no full meaning without the other. Harmonisation issues which can impede efficient and timely implementation of regulations can occur at any stage of the process, starting with the timely publication of the IAEA Regulations, incorporation by the modal organisations, adoption by national competent authorities and finally, rendered operational by industrial transport organisations. Both, the regulator and the transporter, can be more effective in achieving their purposes when they co-operate in the interest of mutual understanding. PATRAM provides one excellent opportunity for such exchange between the regulator and the regulated - there are other important opportunities within the IAEA and international modal organisations. I suggest, however, that more could be done between the regulators and the regulated collectively to share real-life experiences with actually implementing the regulations and operating within them, and to draw appropriate lessons. In the case of the international transport safety regulatory regime, it is the nuclear transport industry, such as represented by the World Nuclear Transport Institute (WNTI), which is, of course, the object of transport safety standards and regulations.

1976-12-01

This report examines several aspects of the problems and choices facing the governmental decision maker who must take regulatory actions with multiple decision objectives and attributes. Particular attention is given to the problems facing the U.S. Nuclear Regulatory Commission (NRC) and to the decision attribute of chief concern to NRC, the protection of human health and safety, with emphasis on nuclear power plants. The study was undertaken to provide background information for NRC to use in refining its process of value/impact assessment of proposed regulatory actions. The principal conclusion is that approaches to rationally consider the value and impact of proposed regulatory actions are available. These approaches can potentially improve the decision-making process and enable the agency to better explain and defend its decisions. They also permit consistent examination of the impacts, effects of uncertainty and sensitivity to various assumptions of the alternatives being considered. Finally, these approaches can help to assure that affected parties are heard and that technical information is used appropriately and to the extent possible. The principal aspects of the regulatory decision problem covered in the report are: the legal setting for regulatory decisions which affect human health and safety, elements of the decision-making process, conceptual approaches to decision making, current approaches to decision making in several Federal agencies, and the determination of acceptable risk levels.

This review provides an insight into the regulation of the carbon concentrating mechanisms (CCMs) in lower organisms like cyanobacteria, proteobacteria, and algae. CCMs evolved as a mechanism to concentrate CO 2 at the site of primary carboxylating enzyme Ribulose-1, 5-bisphosphate carboxylase oxygenase (Rubisco), so that the enzyme could overcome its affinity towards O 2 which leads to wasteful processes like photorespiration. A diverse set of CCMs exist in nature, i.e., carboxysomes in cyanobacteria and proteobacteria; pyrenoids in algae and diatoms, the C 4 system, and Crassulacean acid metabolism in higher plants. Prime regulators of CCM in most of the photosynthetic autotrophs belong to the LysR family of transcriptional regulators, which regulate the activity of the components of CCM depending upon the ambient CO 2 concentrations. Major targets of these regulators are carbonic anhydrase and inorganic carbon uptake systems (CO 2 and HCO 3 - transporters) whose activities are modulated either at transcriptional level or by changes in the levels of their co-regulatory metabolites. The article provides information on the localization of the CCM components as well as their function and participation in the development of an efficient CCM. Signal transduction cascades leading to activation/inactivation of inducible CCM components on perception of low/high CO 2 stimuli have also been brought into picture. A detailed study of the regulatory components can aid in identifying the unraveled aspects of these mechanisms and hence provide information on key molecules that need to be explored to further provide a clear understanding of the mechanism under study.

The International Commission on Radiation Protection (ICRP) has been providing recommendations for limitations on radiation exposure for decades. The ICRP recommendations address ionizing radiation and are concerned with protecting humans from its effects. These recommendations assist regulatory and advisory agencies in establishing and promulgating national regulations and practices in radiation Protection. Most countries have incorporated at least some aspect of the recommendations in their regulations since about 1956 when the first basic prowdon standard was Published in ICRP 2. Since that time ICRP has issued two major revisions to the recommendations. ICRP 26 was published in 1977 and ICRP 60 was published in 1991. These last two publications have companion works, ICRP 30 atid ICRP 61, that contain Annual Limits of Intake (ALI) for radiation workers. This report discusses the impacts of ICRP 60 and 61 on transport regulations

Design of shipping packages to transport varying radioisotopic source materials for future space and terrestrial missions

International Nuclear Information System (INIS)

Barklay, C.D.

1995-01-01

The exploration of space will begin with manned missions to the moon and to Mars, first for scientific discoveries, then for mining and manufacturing. Because of the great financial costs of this type of exploration, it can only be accomplished through an international team effort. This unified effort must include the design, planning and, execution phases of future space missions, extending down to such activities as isotope processing, and shipping package design, fabrication, and certification. All aspects of this effort potentially involve the use of radioisotopes in some capacity, and the transportation of these radioisotopes will be impossible without a shipping package that is certified by the Nuclear Regulatory Commission or the U.S. Department of Energy for domestic shipments, and the U.S. Department of Transportation or the International Atomic Energy Agency for international shipments. To remain without the international regulatory constraints, and still support the needs of new and challenging space missions conducted within ever-shrinking budgets, shipping package concepts must be innovative. A shipping package must also be versatile enough to be reconfigured to transport the varying radioisotopic source materials that may be required to support future space and terrestrial missions. One such package is the Mound USA/9516/B(U)F. Taking into consideration the potential need to transport specific types of radioisotopes, approximations of dose rates at specific distances were determined taking into account the attenuation of dose rate with distance for varying radioisotopic source materials. As a result, it has been determined that the shipping package requirements that will be demanded by future space (and terrestrial) missions can be met by making minor modifications to the USA/9516/B(U)F. copyright 1995 American Institute of Physics

The achievement of the effectiveness in the performance of a nuclear regulatory body has been a permanent challenge in the recent history of nuclear regulation. In the post-Fukushima era this challenge is even more important. This article addresses the subject from two complementary points of view: the characteristics of an effective regulatory body and the regulatory approaches. This work is based on the most recent studies carried out by the Committee on Nuclear Regulatory Activities, CNRA (OECD/NEA), as well as on the experience of the Consejo de Seguridad Nuclear, CSN, the Spanish regulatory body. Rafael Cid is the representative of CSN in these project: Diego Encinas has participated in the study on regulatory approaches. (Author)

The U.S. Department of Transportation (DOT) and the U.S. Nuclear Regulatory Commission (NRC) have prepared a comprehensive set of draft guidance for shippers and inspectors to use when applying the newly imposed regulatory requirements for low specific activity (LSA) material and surface contaminated objects (SCOs). These requirements represent significant departures in some areas from the manner in which these materials and objects were regulated by the earlier versions of the regulations. The proper interpretation and application of the regulatory criteria can require a fairly complex set of decisions be made. To assist those trying these regulatory requirements, a detailed set of logic-flow diagrams representing decisions related to multiple factors were prepared and included in the draft report for comment on Categorizing and Transporting Low Specific Activity Materials and Surface Contaminated Objects, (DOT/NRC, 1997). These logic-flow diagrams, as developed, are specific to the U.S. regulations, but were readily adaptable to the IAEA regulations. The diagrams have been modified accordingly and tied directly to specific paragraphs in IAEA Safety Series No. 6. This paper provides the logic-flow diagrams adapted in the IAEA regulations, and demonstrated how these diagrams can be used to assist consignors and inspectors in assessing compliance of shipments with the LSA material and SCO regulatory requirements.

The transport of the energy contained in electrons, both thermal and suprathermal, in solar flares plays a key role in our understanding of many aspects of the flare phenomenon, from the spatial distribution of hard X-ray emission to global energetics. Motivated by recent RHESSI observations that point to the existence of a mechanism that confines electrons to the coronal parts of flare loops more effectively than Coulomb collisions, we here consider the impact of pitch-angle scattering off turbulent magnetic fluctuations on the parallel transport of electrons in flaring coronal loops. It is shown that the presence of such a scattering mechanism in addition to Coulomb collisional scattering can significantly reduce the parallel thermal and electrical conductivities relative to their collisional values. We provide illustrative expressions for the resulting thermoelectric coefficients that relate the thermal flux and electrical current density to the temperature gradient and the applied electric field. We then evaluate the effect of these modified transport coefficients on the flare coronal temperature that can be attained, on the post-impulsive-phase cooling of heated coronal plasma, and on the importance of the beam-neutralizing return current on both ambient heating and the energy loss rate of accelerated electrons. We also discuss the possible ways in which anomalous transport processes have an impact on the required overall energy associated with accelerated electrons in solar flares.

A proposed regulatory framework for road and rail freight transport in South Africa

Directory of Open Access Journals (Sweden)

Wessel Pienaar

2007-09-01

Full Text Available The increase in the number of freight vehicles on South Africa’s rural road network has received substantial attention. Insinuations persist that long-distance road freight haulage is of a somewhat unsavoury economic nature, and that strict economic re-regulation of the land freight transport is necessary. During the 1970s road transport replaced rail carriage as the dominant form of long-distance freight transport (excluding minerals and ore in South Africa. On long hauls road freight carriers transport certain primary products of an organic nature (such as timber, fish and agricultural produce, some semi-finished goods, many finished goods and most consumer goods. Road freight carriers are continuously gaining market share on long-distance links where rail transport is the more cost efficient mode. The greater value added by road freight carriers in comparison with rail transport through service effectiveness is often more than the cost premium paid for utilising their service rather than making use of rail transport. Throughout history, governments have involved themselves in transport. A diverse range of arguments have been advanced for this involvement in transport, including the following:Control of excessive competition, co-ordination of transport, integration of transport with economic policy, maintenance of safety, security, and order, provision of costly infrastructure, provision of public goods, recovery of the true resource cost of transport inputs, regulation of harmful conduct and externalities, restraint of monopoly power, and social support. A set of nine instruments can be identified that governments apply to influence the performance of the freight transport industry: Legislation, direct supply, fiscal measures, monetary measures, moral appeal and persuasion, policies relating to strategic commodities, procurement policy, provision of information, and research and development.

2015-01-01

Full Text Available Background: Clinical development of antiepileptic drugs is demanding due to complex character of the disorder and to diversity of its forms and etiologies. Objective: The aim of this review was to suggest improvements in regulatory procedures for clinical development of antiepileptic drugs. Methods: The following databases of scientific articles were searched: MEDLINE, SCOPUS and SCINDEKS. In total 558 publications were retrieved. The types of articles selected were reviews, reports on clinical trials and letters to the Editor. Results: There are several changes of regulatory documents necessary for improving process of clinical development of antiepileptic drugs: preference of parallel groups design for add-on trials should be explicit; the noninferiority design for monotherapy clinical trials should be acceptable; restrictive formulations when trials of antiepileptic drugs in children are in question should be avoided; requirements in regard to the efficacy measures should be harmonized among the regulatory bodies; proactive attitude towards discovery of adverse events; and precise requirements for clinical trials specifically designed to prove anti-epileptogenic effects should be made clear. Conclusion: Current regulatory documents are incomplete in many aspects; an international effort to improve and harmonize guidelines for clinical development of antiepileptic drugs is necessary for improvement of this process.

Transportation of failed or damaged foreign research reactor spent nuclear fuel

International Nuclear Information System (INIS)

Messick, Charles E.; Mustin, Tracy P.; Massey, Charles D.

1999-01-01

Since initiating the Foreign Research Reactor Spent Nuclear Fuel (FRR SNF) Acceptance Program in 1996, the Program has had to deal with difficult issues associated with the transportation of failed or damaged spent fuel. In several instances, problems with failed or damaged fuel have prevented the acceptance of the fuel at considerable cost to both the Department of Energy and research reactor operators. In response to the problems faced by the Acceptance Program, DOE has undertaken significant steps to better define the spent fuel acceptance criteria. DOE has worked closely with the U.S. Nuclear Regulatory Commission to address failed or damaged research reactor spent fuel causing a degradation of the fuel assembly exposing fuel meat and to identify cask certificate issues which must be resolved by cask owners and foreign regulatory authorities. The specific issues and implementation challenges associated with the transport of MTR type FRR SNF will be discussed. The information presented will include U.S. Nuclear Regulatory Commission regulatory issues, cask certificate issues, technical constraints, implementation status, and lessons learned. Specific information will also be provided on the latest efforts to revise DOE's Appendix B, Transport Package (Cask) Acceptance Criteria. The information presented in this paper will be of interest to foreign research reactor operators, shippers, and cask vendors in evaluating the condition of their fuel to ensure it can be transported in accordance with appropriate cask certificate requirements.

Goal system for comparative assessments of nuclear fuel transport under security aspects

International Nuclear Information System (INIS)

Behrendt, V.; Schwieren, G.

1983-01-01

Due to the great hazard potential of nuclear fuel transports the possibility always exists during transportation that either a single perpetrator or a group of perpetrators will try to get possession of the nuclear fuel. One can assume that at the end of such illegal actions there will be a politically (or otherwise) motivated extortion. Thinking about security one has to face things like sabotage, attacks from inside or outside the system, robbery and/or dispersion of the transported goods. In respect to the security of nuclear transports we carried out an investigation for the German Ministry of the Interior in order to review the different levels of security of different transport systems. This paper deals with the methodological approach, especially with the goal system and the way we executed the investigation

The civil design requirements of safety related nuclear structures are much more stringent and conservative as compared to that for conventional and industrial structures. Due to the importance of safety and desired reliability in the civil design of nuclear structures, International Atomic Energy Agency (IAEA) and Atomic Energy Regulatory Board (AERB) have provided various safety guides for their safe design. There has been advancement in theoretical and experimental knowledge pertaining to the design, construction, installation, maintenance, testing and inspection of structures, systems, and components (SSCs) of nuclear power plants (NPPs), such that, their quality and reliability is commensurate with safety functions. The well established procedures are available in the form of different codes, standards, guidelines and well proven research work for NPPs. However, such procedures are somewhat limited in nature for design of civil structures in nuclear fuel cycle facilities (NFCF), and till date no separate codes or standards have been published by regulatory authorities in India that cover civil design aspects for NFCF. Hence, design of civil structures of NFCF in India is performed by using different national and international standards, and the recommendations provided by BARC Safety Council (BSC). Present paper focuses civil design aspects for NFCF in India. (author)

Safety criteria for spent-fuel transport. Final report

Goldmann, K.; Gekler, W.C.

1986-10-01

The focus of this study is on the question, ''Do current regulations provide reasonable assurance of safety for a transport scenario of spent fuel, as presently anticipated by the Department of Energy, under the Nuclear Waste Policy Act.'' This question has been addressed by developing a methodology for identifying the expected frequency of Accidents Which Exceed Regulatory Conditions in Severity (AWERCS) for spent fuel transport casks and then assessing the health effects resulting from that frequency. By applying the methodology to an illustrative case of road transports, it was found that the accidental release of radioactive material from impact AWERCS would make negligible contributions to health effects associated with spent fuel transports by road. It is also concluded that the current regulatory drop test requirements in 10 CFR 71.51 which form the basis for cask design and were used to establish AWERCS screening criteria for this study are adequate, and that no basis was found to conclude that cask performance under expected road accident conditions represents an undue risk to the public

NRC review of passive reactor design certification testing programs: Overview, progress, and regulatory perspective

Energy Technology Data Exchange (ETDEWEB)

Levin, A.E.

1995-09-01

New reactor designs, employing passive safety systems, are currently under development by reactor vendors for certification under the U.S. Nuclear Regulatory Commission`s (NRC`s) design certification rule. The vendors have established testing programs to support the certification of the passive designs, to meet regulatory requirements for demonstration of passive safety system performance. The NRC has, therefore, developed a process for the review of the vendors` testing programs and for incorporation of the results of those reviews into the safety evaluations for the passive plants. This paper discusses progress in the test program reviews, and also addresses unique regulatory aspects of those reviews.

Aspectos ambientais no Plano Nacional de Logística e Transporte do Brasil

Full Text Available The Brazilian government has been heavily investing in transportation infrastructure. According to environmental laws, this kind of enterprise must do an environmental impact assessment (EIA. However, the EIA is a regulatory measure applied post-project, which allows for limited project changes. For increasing environmental viability of the project, changes should be done from earlier steps of the project in a regional or national strategic planning context. For the transportation sector, a National Plan on Logistics and Transportation (NPLT recommends aims, targets and plans for Brazil and neighboring countries for the future. We have evaluated the environmental aspects of the NPLT as showed in three reports from 2007, 2009 and 2012. The first report (2007 has summarized the trajectory of transportation planning in Brazil, since the military dictatorship period in the 1970s, showing the necessity of considering environmental impacts from transportation projects and from respecting environmental laws. The following reports indicated the need to expand the modal matrix of transportation, which until then is concentrated on highways, and mentioned the importance of a Strategic Environmental Assessment (SEA. The SEA tool would allow to identify, previously, the cumulative and synergetic effects of the project as predicted in the PNLT; however it still remains as a proposition for improvement in the Brazilian environmental laws. We believe that using SEA oriented by Economic Ecological Zoning (EEZ and some basic concepts of Landscape Ecology and Road Ecology, the protection of environmentally vulnerable regions and priority areas for biodiversity conservation in Brazil would effectively guide the PNLT aims, targets and plans.

International cooperation for the development of consistent and stable transportation regulations to promote and enhance safety and security

International Nuclear Information System (INIS)

Strosnider, J.

2004-01-01

International commerce of radioactive materials crosses national boundaries, linking separate regulatory institutions with a common purpose and making it necessary for these institutions to work together in order to achieve common safety goals in a manner that does not place an undue burden on industry and commerce. Widespread and increasing use of radioactive materials across the world has led to increases in the transport of radioactive materials. The demand for consistency in the oversight of international transport has also increased to prevent unnecessary delays and costs associated with incongruent or redundant regulatory requirements by the various countries through which radioactive material is transported. The International Atomic Energy Agency (IAEA) is the authority for international regulation of transportation of radioactive materials responsible for promulgation of regulations and guidance for the establishment of acceptable methods of transportation for the international community. As such, the IAEA is seen as the focal point for consensus building between its Member States to develop consistency in transportation regulations and reviews and to ensure the safe and secure transport of radioactive material. International cooperation is also needed to ensure stability in our regulatory processes. Changes to transportation regulations should be based on an anticipated safety benefit supported by risk information and insights gained from continuing experience, evaluation, and research studies. If we keep safety as the principle basis for regulatory changes, regulatory stability will be enhanced. Finally, as we endeavour to maintain consistency and stability in our international regulations, we must be mindful of the new security challenges that lay before the international community as a result of a changing terrorist environment. Terrorism is a problem of global concern that also requires international cooperation and support, as we look for ways to

During the Soviet period, the uranium mining operations in Central Asia served as one of the main uranium producers for the Soviet Union (SU) military complex. The regulatory standards for exposure and emissions control to all Soviet Republics were administered by the Ministry of Medium Machine Building and were the same across the USSR. After the collapse of the Soviet Union in 1991, the former Soviet Republics became independent, but also inherited the legacy in the form of wastes, including those from uranium ore processing and tailings and old Soviet regulatory documents, which are mostly inconsistent with the international standards and guidances and need substantial improvements. Many radioactive waste storage facilities in Central Asia, especially in the Kyrgyz Republic and Tajikistan, are located in regions of seismic activity, in landslide- and mud flow-prone areas and areas subject to flooding and high ground water levels, and near the banks of the rivers that form the base of the large water basin of the Central Asian region. Many tailings are situated near towns, other populated areas and state borders, and they represent a long-term hazard to health and the environment. In regard to the legal and regulatory framework, it should be noted that none of the Central Asian countries have a National Policy and Strategy for Radioactive Waste Management developed and approved by the Governments. Existing regulatory documents do not address the issues regarding safety assessments and safety cases or the implementation of long-term institutional control and monitoring of the abandoned dumps with radioactive wastes (RW) or future RW disposal sites, neither during operation nor after their closure. There is also a need to develop safety criteria (reference levels) and determine measures to be taken for existing exposure situations (past practices). In addition, there is a lack of safety requirements for different types of disposal facilities in accordance with the

Radiation protection and nuclear safety are of paramount importance when operating shielded cells in hot labs and using remote handling tools. Therefore, various aspects should be ensured throughout the lifecycle of nuclear installations disposing of such type of equipment. The presented aspects are the results of the regulatory body experience with this kind of installations (licensing, operations, operating experience, events). This paper will deal with safety considerations such as filtration, fire protection, shielding, ventilation, waste management, separation of the product fluxes, leak tightness, introduction of equipment, interlocks, failsafe components, piloting software, monitoring and education/training.

Some Aspects of Thermal Transport across the Interface between Graphene and Epoxy in Nanocomposites.

Owing to the superior thermal properties of graphene, graphene-reinforced polymer nanocomposites hold great potential as the thermal interface materials (TIMs) dissipating heat for electronic packages. However, this application is greatly hindered by the high thermal resistance at the interface between graphene and polymer. In this paper, some important aspects of the improvement of the thermal transport across the interface between graphene and epoxy in graphene-epoxy nanocomposites, including the effectiveness of covalent and noncovalent functionalization, isotope doping, and acetylenic linkage in graphene are systematically investigated using molecular dynamics (MD) simulations. The simulation results show that the covalent and noncovalent functionalization techniques could considerably reduce the graphene-epoxy interfacial thermal resistance in the nanocomposites. Among different covalent functional groups, butyl is more effective than carboxyl and hydroxyl in reducing the interfacial thermal resistance. Different noncovalent functional molecules, including 1-pyrenebutyl, 1-pyrenebutyric acid, and 1-pyrenebutylamine, yield a similar amount of reductions. Moreover, it is found that the graphene-epoxy interfacial thermal resistance is insensitive to the carbon isotope doping in graphene, while it can be reduced moderately by replacing the sp(2) bonds in graphene with acetylenic linkages.

This work analyzed and summarized systematically various regulatory requirements that are necessary to develop digital nuclear instrumentation and control (I and C) systems, especially safety systems. The requirements are categorized into system, hardware, software, and quality assurance aspects. This report provides the explanations of terms and abbreviations to help readers understand. Furthermore, appendices of this report summarize the code and standards corresponding to each principal regulatory requirement. The hierarchical structure of regulatory requirements has Nuclear Energy Laws, Enforcement Regulations of Nuclear Energy Laws, and Notifications of Ministry of Science and Technology as utmost level requirements [In case of the US, 10 CFR 50 Appendix A, 10 CFR 50 Appendix B, 10 CFR 50.55a(h), 10 CFR 50.49, etc.]. The requirements include the Draft Regulatory Guidelines for Digital I and C Systems [In case of the US, Standard Review Plan (NUREG-0800), Regulatory Guide, Branch Technical Position (BTP)], KEPIC as standards [In case of the US, IEEE Standards, IEC Standards, ISA, Military Standard, etc.], and various reports issued by Korea Institute of Nuclear Safety [In case of the US, NUREG reports, EPRI reports, etc.].

Regulatory uncertainty and the associated business risk for emerging technologies

International Nuclear Information System (INIS)

Hoerr, Robert A.

2011-01-01

An oversight system specifically concerned with nanomaterials should be flexible enough to take into account the unique aspects of individual novel materials and the settings in which they might be used, while recognizing that heretofore unrecognized safety issues may require future modifications. This article considers a question not explicitly considered by the project team: what is the risk that uncertainty over how regulatory oversight will be applied to nanomaterials will delay or block the development of this emerging technology, thereby depriving human health of potential and substantial benefits? An ambiguous regulatory environment could delay the availability of valuable new technology and therapeutics for human health by reducing access to investment capital. Venture capitalists list regulatory uncertainty as a major reason not to invest at all in certain areas. Uncertainty is far more difficult to evaluate than risk, which lends itself to quantitative models and can be factored into projections of return on possible investments. Loss of time has a large impact on investment return. An examination of regulatory case histories suggests that an increase in regulatory resting requirement, where the path is well-defined, is far less costly than a delay of a year or more in achieving product approval and market launch.

'Resilience thinking' in transport planning

OpenAIRE

Wang, JYT

2015-01-01

Resilience has been discussed in ecology for over forty years. While some aspects of resilience have received attention in transport planning, there is no unified definition of resilience in transportation. To define resilience in transportation, I trace back to the origin of resilience in ecology with a view of revealing the essence of resilience thinking and its relevance to transport planning. Based on the fundamental concepts of engineering resilience and ecological resilience, I define "...

Regulatory aspects of the use of PSA to evaluate technical specifications

International Nuclear Information System (INIS)

Rumpf, J.

1991-01-01

Based on experiences gained in PSA activities the regulatory body of the GDR initiated a programme to investigate the feasibility of using PSA for the evaluation of technical specifications. This programme is just under work. In addition, to improve PSA, the GDR takes part in a programme which is aimed at performing plant specific level 1, PSA as well as and which enables operating organizations to carry out PSA on their own. The most important of some preliminary general findings presented in this paper are: - Technical specifications form a well established envelope of operational conditions and procedures. A total re-evaluation is not considered necessary; Probabilistic evaluation of technical specifications should be an integrated part of PSA activities (at least level 1). Single assessment is not considered reasonable; Probabilistic evaluation of technical specifications has to be based on plant specific information and realistic accident sequence calculations; Up to now no quantitative probabilistic criteria for technical specifications have been established.

Regulatory aspects of teratology: role of the Food and Drug Administration

International Nuclear Information System (INIS)

Kelsey, F.O.

1982-01-01

The Food and Drug Administration is a scientific regulatory agency whose consumer protection activities cover a wide range of products including foods and additives, and pesticide residues on foods; drugs; cosmetics; medical devices; and radiation-emitting electronic products. Amongst its concerns is the possible teratogen effects of regulated products to which the pregnant woman is exposed. The policies and programs of the agency directed toward reducing such risks to the unborn are reviewed. These measures include guidelines for animal reproduction studies and for clinical trials involving women to childbearing potential; labeling of products to disclose known or possible harm to the fetus or embryo; surveillance procedures designed to detect previously unsuspected adverse effects of marketed products; research activities designed to develop better understanding of developmental toxicology and improved techniques for detecting embryocidal and embryotoxic effects; and educational efforts directed both to professionals and the public regarding hazards to the unborn of agency-regulated products

Stowing of radioactive packages, materials or objects for their transport. Guide nr 27, Release of 30 August 2016

International Nuclear Information System (INIS)

2016-01-01

A good package stowing is part of an in-depth defence approach to ensure the safety of transport operations in the case of radioactive materials. This guide thus presents a set of recommendations to ensure this safety, recalls regulatory requirements, and presents recommendations made by the ASN for specific stowing training. This document concerns all kinds of transports (road, rail, river, sea, and air). After having indicated the different regulatory references, standards and recommendations, it proposes an overview of the applicable regulatory framework and technical requirements for stowing in France and in the EU in the case of road transport, of rail transport and of sea transport, and in France and in the world for the case of air transport. The next part details regulatory requirements and recommendations made by the ASN for the stowing of radioactive loads: commitment of the company's management, specific training for concerned personnel, definition of packing and stowing plans or of specific instructions, selection of the stowing system, adequacy of the used stowing equipment, documentation to achieve a good stowing, stowing quality control. Then, recommendations are made for the undertaking of a specific training on radioactive load stowing: training modalities, training content, training objectives (for designers, operators and controllers)

The IAEA Office of Nuclear Security is working cooperatively with the U.S. Department of Energy's Global Threat Reduction Initiative, European Union and Australia to provide transport security assistance to countries throughout the world. Assistance is available to countries in reviewing and upgrading their transport security programs at all levels: (1) National level (regulatory and other government agencies); and (2) Operator level (shippers and carriers). Assistance is directed at implementing a consistent level of security throughout the life cycle of radioactive material (same level of security during transport as when in a fixed facility) Upgrade assistance can include: (1) Expert advisory missions to provide advice and guidance; (2) Training courses for regulatory, governmental and industry personnel; (3) Transport security awareness; (4) Detailed training on designing and implementing transport security programs; (5) Planning to identify and prioritize needs (developing security approaches and plans); (6) Developing model security plans and procedures; and (7) Equipment (vehicles, packages, command and control equipment, etc.). Country visits are now being scheduled to initiate transport security cooperative activities. A training course has been developed to assist countries in developing and implementing transport security programs. The training course has been given as a national training course (three times) and as a Regional training course (three times). The course addresses recommended security provisions for the transport of all radioactive material.

Csoevari, M.; Csicsak, J.; Lendvai, Zs.; Varhegyi, A.; Nam, A.

2001-01-01

In Hungary, there are numerous acts and decrees concerning the uranium ore mining remediation, including the aspects of radiation protection and release limits. The most important ones are: Mining Act, Atomic Energy Act, Environmental Protection Act, Water Management Act, Government Decrees No. 115/1993 and 152/1995. For radiation protection regulation the baselines are codified in the Hungarian National Standard MSZ 62/1-1989, while the release limits are prescribed in the order No. 3/1984 of Hungarian Water Authority (OVH), and in the standard MSZ 450/1-1989. According to the above documents, the limits for annual effective dose-equivalent are: (a) 50 mSv for persons occupied in nuclear industry or working with radioactive isotopes, this is relevant to mining and processing of uranium ore, (b) 5 mSv for the critical group of members of the public, in the case of long exposure this value could not exceed 1 mSv/a. In accordance to the EC directives, it is expected that the limit for the public will be decreased soon to 1 mSv/a. Release limits for discharge of natural radionuclides (U, Th, Ra, Rn) in surface water: (a) for uranium maximum 2 mg/dm 3 , (b) for radium-226 maximum 1.1 Bq/dm 3 . There are no general discharge limits for other pollutants in waste water, but the competent authorities may give individual limits if asked. Detailed limits are given only for drinking water for toxic and chemical components. Release limits for discharge of heavy metals are listed in order No. 3/1984 OVH. Of course, numerous licenses and permissions have to be obtained for remediation. The most important ones are the Environmental Protection Permission, based on a detailed environmental impact assessment, and the technical reclamation plans. Numerous authorities are involved in the licensing procedures (e.g. Mining Authority, Environmental Protection Authority, Water Authority, National Municipal Health Authority, etc.). (author)

Activation of counter-regulatory mechanisms in a rat renal acute rejection model

Salomon Daniel R

2008-02-01

Full Text Available Abstract Background Microarray analysis provides a powerful approach to identify gene expression alterations following transplantation. In patients the heterogeneity of graft specimens, co-morbidity, co-medications and the challenges in sample collection and preparation complicate conclusions regarding the underlying mechanisms of graft injury, rejection and immune regulation. Results We used a rat kidney transplantation model with strict transplant and sample preparation procedures to analyze genome wide changes in gene expression four days after syngeneic and allogeneic transplantation. Both interventions were associated with substantial changes in gene expression. After allogeneic transplantation, genes and pathways related to transport and metabolism were predominantly down-regulated consistent with rejection-mediated graft injury and dysfunction. Up-regulated genes were primarily related to the acute immune response including antigen presentation, T-cell receptor signaling, apoptosis, interferon signaling and complement cascades. We observed a cytokine and chemokine expression profile consistent with activation of a Th1-cell response. A novel finding was up-regulation of several regulatory and protective genes after allogeneic transplantation, specifically IL10, Bcl2a1, C4bpa, Ctla4, HO-1 and the SOCS family. Conclusion Our data indicate that in parallel with the predicted activation of immune response and tissue injury pathways, there is simultaneous activation of pathways for counter regulatory and protective mechanisms that would balance and limit the ongoing inflammatory/immune responses. The pathophysiological mechanisms behind and the clinical consequences of alterations in expression of these gene classes in acute rejection, injury and dysfunction vs. protection and immunoregulation, prompt further analyses and open new aspects for therapeutic approaches.

Foreword—welfare aspects of the long distance transportation of animals

Directory of Open Access Journals (Sweden)

Gardner Murray

2008-03-01

Full Text Available The long distance transport of animals within countries, between countries, across regions and across continents is increasing significantly and is also changing in nature. Statistics from the International Trade Centre of the United Nations Conference on Trade and Development and the World Trade Organization show that the value of world trade in live animals soared from US$8.7 billion in 2000 to US$12.1 billion in 2005. This enormous figure would be even greater if zoo animals, wildlife and illicit traffic were included.The history of animal transportation goes back thousands of years. It remains a legitimate practice to this day provided proper measures are taken to protect animal well-being and health. What has made circumstances different in the 21st century is the nature of transport (land, sea and air, the volume of traffic and a public awareness of welfare issues with demands that animals be treated humanely and in accordance with best contemporary practices. This increased volume of transport creates an unprecedented risk for disseminating infectious diseases, including those that may affect people.Key public concerns about animal welfare relate to factors such as a lack of infrastructure and investment in training, research and standards development, as well as indifference and neglect. The live animal transportation industries are threatened when these deficiencies are not corrected.Fortunately, a number of countries foresaw these problems and introduced a series of activities to support good animal welfare practices. Many recognised the clear connection between animal welfare, health and husbandry practice, and established policy settings to include these activities under a veterinary public and animal health umbrella. Recognising its critical importance, the World Organisation for Animal Health (Office International des Epizooties: OIE in its IVth Strategic plan (points a to b, identified animal welfare as a key issue and launched a

Regional, national and international security requirements for the transport of nuclear cargo by sea

International Nuclear Information System (INIS)

Booker, P.A.; Barnwell, I.

2004-01-01

Since the beginning of the nuclear age in the 1940's, the world has focused on the immense possibilities of nuclear power with both its destructive and productive capabilities. The civil nuclear industry in the UK, as in most nuclear weapons states, grew from the military facilities built in the post war years under the political climate of the Cold War. In the early years of the industry, civil and defence nuclear facilities were inextricably linked both in public perceptions and the regulatory infrastructure under which they operated. The nuclear arms race and the spread of communism overshadowed people's perceptions of there being two separate uses of nuclear material. This was a double edged sword which initially allowed the industry to develop largely unhindered by public concerns but latterly meant the industry could not break away from its roots and to many is still perceived as a dangerous and destructive force. Regulatory frameworks governing all aspects of the industry have developed both nationally and internationally driven by valid public concerns, political agendas and an international consensus that the unregulated use of nuclear material has catastrophic possibilities on an international scale. With the internationalisation of the civil nuclear industry and the costs associated with developing facilities to fully support each stage of the fuel cycle, from enrichment, fuel manufacturing, reprocessing and waste remediation, it became inevitable that a transport infrastructure would develop to make best use of the facilities. Regulations, both national and international are implicit in ensuring the security of nuclear material in transit. Due to the physical size of many of the irradiated fuel packages and implications of the changes to transport safety regulations, international transports of nuclear material, other than within mainland Europe, is predominantly carried out by sea

Seo, Myung Hwan; Hong, Sung Wook; Park, Jin Beak [Korea Radioactive Waste Agency, Technology Institute, Daejeon (Korea, Republic of)

2016-09-15

Korea Radioactive Waste Agency (KORAD) began to operate the low and intermediate level radioactive waste disposal facility in Gyeongju and to transport the radioactive waste containing radioactive isotopes from Daejeon to the disposal facility for the first time at 2015. For this radioactive waste transportation, in this study, radiological impact assessment is carried out for workers and public. The dose rate to workers and public during the transportation is estimated with consideration of the transportation scenarios and is compared with the Korean regulatory limit. The sensitivity analysis is carried out by considering both the variation of release ratios of the radioactive isotopes from the waste and the variation of the distances between the radioactive waste drum and worker during loading and unloading of radioactive waste. As for all the transportation scenarios, radiological impacts for workers and public have met the regulatory limits.

Transporters govern the access of molecules to cells or their exit from cells, thereby controlling the overall distribution of drugs to their intracellular site of action. Clinically relevant drug-drug interactions mediated by transporters are of increasing interest in drug development. Drug transporters, acting alone or in concert with drug metabolizing enzymes, can play an important role in modulating drug absorption, distribution, metabolism and excretion, thus affecting the pharmacokinetics and/or pharmacodynamics of a drug. The drug interaction guidance documents from regulatory agencies include various decision criteria that may be used to predict the need for in vivo assessment of transporter-mediated drug-drug interactions. Regulatory science research continues to assess the prediction performances of various criteria as well as to examine the strength and limitations of each prediction criterion to foster discussions related to harmonized decision criteria that may be used to facilitate global drug development. This review discusses the role of transporters in drug development with a focus on methodologies in assessing transporter-mediated drug-drug interactions, challenges in both in vitro and in vivo assessments of transporters, and emerging transporter research areas including biomarkers, assessment of tissue concentrations, and effect of diseases on transporters.

Sepúlveda, Francisco V.; Pablo Cid, L.; Teulon, Jacques; Niemeyer, María Isabel

2015-01-01

K+ channels fulfill roles spanning from the control of excitability to the regulation of transepithelial transport. Here we review two groups of K+ channels, pH-regulated K2P channels and the transport group of Kir channels. After considering advances in the molecular aspects of their gating based on structural and functional studies, we examine their participation in certain chosen physiological and pathophysiological scenarios. Crystal structures of K2P and Kir channels reveal rather unique features with important consequences for the gating mechanisms. Important tasks of these channels are discussed in kidney physiology and disease, K+ homeostasis in the brain by Kir channel-equipped glia, and central functions in the hearing mechanism in the inner ear and in acid secretion by parietal cells in the stomach. K2P channels fulfill a crucial part in central chemoreception probably by virtue of their pH sensitivity and are central to adrenal secretion of aldosterone. Finally, some unorthodox behaviors of the selectivity filters of K2P channels might explain their normal and pathological functions. Although a great deal has been learned about structure, molecular details of gating, and physiological functions of K2P and Kir K+-transport channels, this has been only scratching at the surface. More molecular and animal studies are clearly needed to deepen our knowledge. PMID:25540142

Interpretation of ALARA in the Canadian regulatory framework

Energy Technology Data Exchange (ETDEWEB)

Utting, R. [Atomic Energy Control Board, Ottawa, Ontario (Canada)

1995-03-01

The Atomic Energy Control Board (AECB) is responsible for the regulation of all aspects of atomic energy in Canada. This includes the complete nuclear fuel cycle from uranium mining to long-term disposal of nuclear fuel, as well as the medical and industrial utilization of radioisotopes. Clearly, the regulatory approach will differ from practice to practice but, as far as possible, the AECB has attempted to minimize the degree of prescription of regulatory requirements. The traditional modus operandi of the AECB has been to have broad general principles enshrined in regulations with the requirement that licensees submit specific operating policies and procedures to the AECB for approval. In the large nuclear facilities with their sophisticated technical infrastructures, this policy has been largely successful although in a changing legal and political milieu the AECB is finding that a greater degree of proactive regulation is becoming necessary. With the smaller users, the AECB has for a long time found it necessary to have a greater degree of prescription in its regulatory function. Forthcoming General Amendments to the Atomic Energy Control Regulations will, amongst other things, formally incorporate the concept of ALARA into the Canadian regulatory framework. Within the broad range of practices licensed by the AECB it is not practical to provide detailed guidance on optimization that will be relevant and appropriate to all licensees, however the following general principles are proposed.
