According to arrangement between the State Office for Nuclear Safety (SUJB) and the Federal Ministry of Agriculture and Forestry, Environment and Water Management, Radiation Protection Division (BMLFUW) there is prepared and regularly tested emergency data exchange between the ESTE systems at the SUJB and at the BMLFUW. The ESTE system is support instrument for off-site emergency response and its main goals in case of severe reactor accidents are: .detection of the way of the release from the reactor core to the environment .detection of the state of the reactor core, .prediction of the source term, .estimation of really observed release rate to the atmosphere, .calculations of radioactive clouds dispersion and radiological impacts assessments. The este systems are implemented at the Emergency Response Centre of the Czech Republic (SUJB) in Prague and Austrian versions are implemented at the Crisis Centre of the Austrian Republic (BMLFUW) in Vienna. The main objective of data exchange according to the above mentioned agreement is to extend bilateral information exchange and make a step in the direction of harmonizing emergency management in case of radiological accidents. Automatic data exchange between the este systems at the SUJB Prague and at the BMLFUW Vienna is performed for testing and training regularly once a month. This assists us to have the system ready in any time. (authors)

The goal was to define more closely the terms of formation of tripuhyite, which was synthesized in the laboratory under different conditions. In the first series of experiments the effect of the chemical composition of the solution (molar ratio Fe: Sb, As concentration) on the structural parameters and chemical composition tripuhyite was monitored. The second series of experiments focused on the effect of pH values of the solution on the crystallization of this mineral. Synthetic samples were examined primarily by X-ray powder diffraction analysis, chemical composition of the samples was determined by electron probe microanalysis. The concentration of the elements in the residual solution was determined by AAS and ICP-AES. Experimental studies confirmed the ability of tripuhyite crystallization in a wide range of chemical composition of the solution, what is reflected in the structural parameters and chemical composition of the resulting phase. The possibility of tripuhyite crystallization at high dispersion of pH values (pH 1-8) was also confirmed. (author)

Round goby has a high invasive potential and huge expansive scattering. A suitable reproduction strategy probably helps him in successful colonizing of new territories. This allows him to create offspring also in the environments with constantly changing conditions. The aim of this work was to: (1) Analyze vital signs flexibility of bull populations living in different habitats (Karloveske rameno - less stable habitat, Cunovo - stable habitat). (2) Determine whether the disturbance, which occurred in 2010 on a site Karloveske rameno expressed in reproductive parameters of this population. To achieve the objectives it was necessary to analyze reproductive parameters of the bull individuals from both locations. The population of goby from Karloveske rameno has statistically significantly greater total mean of oocytes and oocyte diameter in different size groups and a higher average value of gonadosomatic index compared with a population of Cunovo. The absolute fertility and relative fertility was lower in Karloveske rameno population despite the fact that a given population had a greater range of values of absolute fertility. (author)

Full text: Emergency preparedness to nuclear accidents (radiation emergency preparedness) is a part of general emergency preparedness and crisis management in the Czech Republic. The bases for it were given in 1997 when radiation emergency preparedness was defined and requirements to it were given in Act No. 18/1997 Coll., so called the Atomic Act, which entered into force in July 1997. In 2000, the bases for general emergency preparedness and crisis management in the Czech Republic were given namely in two acts - in Act No. 239/2000 Coll., an integrated rescue system, and in Act No. 240/2000 Coll., on crisis management. Both these acts entered into force on 1 January 2001. The Atomic Act determines duties of licensees in the field of preparedness. One of them is obligation to prepare and submit to SUJB the on-site emergency plan as one of attachments to his application for the licence. (The licence can be issued if defined documents, including this plan, are approved.) The licensee is obliged, under conditions given in detail in one of implementing regulation, to prepare a proposal of the emergency planning zone and submit it to SUJB. In the Act, there are also given the requirements for licensee's actions in case of a radiation emergency occurrence. On the other hand the Atomic Act names what are SUJB competencies and also what are these ones from the point of view of radiation emergency. Among others SUJB establishes the emergency planning zone, controls the activity of the National Radiation Monitoring Network, provides for the activities of an Emergency Response Centre and ensures the availability of background information necessary to take decisions aimed at reducing or averting exposure in the case of a radiation accident. SUJB has its own crisis staff; it has 4 shifts, which change regularly weekly. About 50 SUJB employees divided into 12 different functions are members of this staff. The Emergency Response Centre (ERC) of SUJB organizes work of this staff

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.

The central registration system in radiation protection is created in the Czech Republic since the 1997 year. Since that time the central registries of licensees, ionizing radiation sources (IRS) and occupational of workers doses has been developed by the State Office for Nuclear Safety (SUJB) in accordance with the demands of the new Czech legislation. The core of this complex information system is created by the Central Register of Licensees (CRL). The Central Register of Occupational Exposure (CROE) and the Central Register of Ionising Radiation Sources (CRIRS) are connected to CRL and provides with the list of workers their doses and relevant sources for each licensee. The Central Register of Approvals (CRA) issued by SUJB has been also created in 2002 and it was implemented into the system. The further register of inspections is recently under development. The whole system is operated in Oracle database. CRL registers all relevant information on the level of licensee, their workplaces and also on the level of smaller working units (labs, buildings, ..) where is necessary for more precise information about the placement of sources. The data are updated continuously. CROE collects personal and dosimetric data for all monitored workers in whole country. This register also includes the information on the personal radiation passports distributed by SUJB to external workers. CRIRS registers sealed IRS, devices with sealed IRS, generators and specification of workplaces with unsealed IRS. Users are obliged to report information on new source specified by Decree on radiation protection within one months. They shall report also all changes of registered data including the transfer of source to another user or to final disposal. CRA enables to issue automatically the licence in unified form and provides users with the different control tools of issued licences. Described comprehensive information system serves as very important and useful tool for effective regulation

There in National Personnel Dosimetry Service (NPDS) the implementation of the control system to guarantee the credibility of the measured personal dose equivalents results was given on the basis of the international recommendations published by the European Commission and the IAEA and in particular of the decree of the SUJB No. 132/2008 Coll. The quality control and the quality assurance are carried out in all three personal dosimetry services introduced in NPDS: in the film badge, thermoluminescent (TL) and neutron dosimetry. (authors)
This paper elaborated the complexity of the licensing process, concerning fuel core design and fuel management. All activities of the Czech Regulatory Body including activities, which shall require the State Office for Nuclear Safety (SUJB) license or authorization are based on legal framework. The licensing process consists of three major stages during which demonstration of safety is to be submitted by the applicants and reviewed and assessed by the regulatory body. The regulatory review and assessment leads to a series of regulatory decisions, which result in granting of an authorization (or the refusal) for site, construction and operation permits. To receive each of these permissions, the licensee has to submit to the SUJB Safety Analysis Reports (preliminary or final); technical specifications for safe operation; programs for non-active and active test (fuel loading, physical start-up, power start-up, trial operation); programs for quality assurance and quality control. Special attention is given to the design reliability and safety related influences of any design changes and usage of new fuel system design. The design compatibility should be reviewed especially from the standpoint of: 1) hermal hydraulic properties (vibration, hydraulic resistance, CHF correlation, fuel rod bowing, effect of spacing grids, pressure losses); 2) technical properties (rigidity, cycling fatigue, wear, cladding abrasion, deformation by external forces, kinetics of control assemblies drop); 3) chemical properties (corrosion, hydriding); 4) neutronic-physical properties (peaking factors, influence of different enrichments, water-uranium ration, shutdown reactivity margin, stability, maximum speed of the reactivity insertion, both calculated and experimental. The licensee is encouraged not only to show the fulfillment of the regulatory requirements but also to provide sufficient arguments with evidence that the safety of the total NPP is maintained
The paper provides the overview of the current situation and problems connected with the management of the medical and occupational exposure control in the Czech Republic in the context of the harmonisation process of legislation within the European Union. The entire Czech legislation has undergone an extensive reconstruction during past ten years. Concerning the radiation protection the Act No. 18/1997 Coll. (Atomic Act) came into force on 1. July 1997. In parallel with the Atomic Act, the procedural Decrees have been adopted by State Office for Nuclear Safety (SUJB). As well as the Atomic Act, these Decrees are based on the internationally adopted principles and recommendations of nuclear safety and radiation protection given by IAEA IBSS, No. 115/1994, ICRP Publication 60/1990. At the present the intensive process of harmonisation of the Atomic Act and procedural Decrees with the EU Directive 96/29/EUROATOM and other directives issued by EU in the field of radiation protection is being carried out. New version of the Atomic Act as the Act No. 13/2002 has been already published and came into force on July 2002 as well as the new Decree No.307/2002 on radiation protection

The ESTE system (Emergency Source Term Evaluation) is support instrument for off-site emergency response and its main objective is to assist to the crisis staff: - to mitigate radiological consequences of significant releases; - to manage the protective measures; - to manage emergency monitoring. At national level the ESTE system are implemented at the Emergency Response Centre of the Czech Republic (SUJB) and Austrian versions are implemented at the Crisis Centre of the Austrian Republic (BMLFUW). ESTE system can now be utilized not only in close (40 km) vicinity of the point of the release (NPP), but radiological impacts are now calculated across the whole country or over the country border. Puff Trajectory Model (PTM) with the background of geographical information system (GIS) is included in este. Numerical weather prediction data (wind fields) predicted for the whole or the part of the country are online connected with este and utilized for the puffs movement simulation and impacts calculations. It means that not only meteorological data from the point of release (measured or predicted), but 'meteorological data wind field' predicted for larger region across the country are used by the este system.

The framework of the Radon programme in the Czech republic includes both precautionary measures and interventions. The programme informally started in early eighties has been now incorporated in national legislation (Atomic Act, Radiation Protection Decree, etc.). Aim of precautionary measures is to avert construction of building above natural radiation guidance levels (200 Bq/m 3 for indoor radon concentration and 0.5 Sv/h for gamma dose rate) by protection of new buildings against soil radon ingress, by regulation of natural radioactivity in building materials and supplied water. Aim of interventions is to identify buildings affected by enhanced natural radioactivity and help owners to put into effect reasonable remedial measures. Two sets of intervention levels for indoor natural exposure were established: guidance intervention levels 400 Bq/m 3 (indoor radon), 1.0 Sv/h (indoor gamma dose rate) and limit values 4000 Bq/m 3 and 10 Sv/h. The radon programme is based both on governmental and private activities. The governmental activities include representative and targeted indoor radon survey, subsidy for radon mitigation, mitigation test measurements and public information on radon issue. The private activities include radon measurement (radon index of building site, indoor measurements, radon diagnosis) and remedial measures. More than 100 commercial companies were authorised by Radiation Protection Authority (SUJB) to provide these measurements

In-service inspection (ISI) programme of piping systems based on Riskinformed In-service Inspections (RI-ISI) approach represents for the WWER NPP licensee first overall systematic conceptual solution of the problems associated with design and design modifications of ISI programme for piping systems. The approach enables to consider possible savings and comparison of in-service inspection programmes according to more objective criteria including those calculated in PSA, in contrast to present much empiric experience collected by manufacturers, operators and ISI vendors in the past. Service experience has shown limited correlation between the deterministic ISI requirements and actual field failures or degradation mechanisms. Where field failures have been observed in piping, they have generally been due to either material concerns (e.g., Intergranular Stress Corrosion Cracking) or stress/cycling mechanisms not identified in the original design basis documents (e.g., thermal stratification), and therefore would not be selected for inspection under current requirements. Risk-informed in-service inspections represent integrated multidisciplinary approach to the in-service inspection programme fulfilling the enhanced requirements of the Czech Regulatory Body (SUJB) for defence in depth concept applied to weld joints of safety related components, application of qualified NDT methods/techniques and introducing of inspections for cause approach. Inspections for cause take into account analysis of both active and potential degradation mechanisms specific to piping system concerned. Simultaneously, this approach enables the licensee to reach, in cases justified from safety point of view, economic savings resulting from lowering of both number and extent of performed in-service inspections and optimisation of their performance. RI ISI pilot study based in majority on EPRI methodology implemented for WWER type reactors has been performed for LP ECCS (Low Pressure Emergency
The Chisobox experimental irradiator was installed at the Faculty of Medicine in Hradec Kralove, Radioisotope Laboratories and Vivarium, for the purposes of the scientific research of ionizing radiation effects on the living organisms. The irradiator was put into operation in 1977. After 1989, its use has been - significantly reduced and it was only employed for the sterilization of medical materials and aids as well as for the radiation treatment of antique and museum things having wood-worm. In January 2001, its next operation was determined by the SUJB decision (i.e. The State Office for Nuclear Safety) in which the constancy tests for all individual ionizing radiation sources being part of the system were required. As the f constancy tests were not performed at that time, the Faculty Management decided for the -- decommissioning of the irradiator in June 2001. In 2003, the Faculty of Medicine announced a tender for the category III workplace disposal. Primarily, the VF, a.s. in cooperation with the SURAO Prague (i.e. the Radioactive Waste Repository Authority) were to have disposed this workplace, and a hot cell designed to be built in Litomerice by the SURAO was to have been used for this project. However, the Faculty of Medicine got a grant for the irradiator disposal in 2004 providing that the disposal had to be finished in the same year. For this reason, the complete project has been assigned to the VF, a.s. Company, which put its hot cell into operation in 2004. The VF, a.s. Company finished the disposal of the irradiator in October/November 2004. After the agreement with the SURAO in April 2005, the sealed sources placed in the storage baskets were put into a newly manufactured container -a non-standard storage unit -and transported to be stored in the URAO Richard in Litomerice.

The European Study on Occupational Radiation Exposure called ESOREX was initiated by the European Commission in the 1997 year. The objectives of this European study are: (1) to provide the European Commission and the national competent radiation protection authorities with reliable information on how personal radiation monitoring, reporting and recording of dosimetric results is structured in European countries; (2) to collect reliable and directly comparable data on individual and collective radiation exposure in all occupational sectors where classified workers are employed. Therefore, it is important to receive information about the levels of individual personal radiation doses to workers in the different sectors and the trends and developments of these doses over a period of several years; (3) at present, all 25 European Union Member States, plus Bulgaria, Iceland, Norway, Romania and Switzerland, participate in the study; and (4) the study was executed under the leadership of German BfS in co-operation with Czech SUJB. First results and analyses based on the data collected in the previous studies are presented in the paper 'Frasch, Petrová: Dose trends in occupational radiation exposure in Europe-Results from the ESOREX project'. As a result of a call for tender of the European Commission/DGTREN in the year 2003, the new ESOREX study called 'ESOREX2005' has been initiated. This study will end at the year 2007 and its main objectives are-to finalise the updating of the country-wise reports by describing the current situation in the field of occupational exposure control, evaluation and registration of personal doses of radiation workers and as a second part of the study, to collect dosimetric data for the period 2001-2005.
This bulletin contains information about activities of the Nuclear Regulatory Authority of the Slovak Republic (UJD). In this leaflet the public communications activities at the UJD are presented. The level of public relations is one of the most sensitive areas in society life and it is one of the crucial factors of nuclear power acceptability both currently and in the future. The 'Atomic Act (130/1998 Coll.)' and the 'Freedom Information Act (211/2000 Co/l.)' are directly related to the presentation of objective data on population health and safety protection and on nuclear facility impacts upon man and his environment. In Slovakia, UJD holds the supreme competencies on nuclear safety public information. A major element of the information is to demonstrate that the field of nuclear energy use has its binding rules in the Slovak Republic and their observance is guaranteed by the state. A central state administration authority, UJD furnishes regular, comprehensible and independent information on installation nuclear safety, including information on the management of RAW, spent nuclear fuel, nuclear material and control and records thereof. As early as 1995 were the foundations laid at UJD for the concept of wide-ranging public information on UJD activity and nuclear installation safety by opening the Information Centre that provides through its activity public and media communications, which helps create in the public a favourable image on independent state surveillance over nuclear safety. UJD sends out 70-80 press releases on its domestic and foreign activities annually to the Slovak Press, dailies and electronic media. UJD is together with SUJB the publisher of the journal N uclear Energy Safety'. UJD domestic and foreign activities are published in UJD bulletins, Slovak and European Nuclear Society journals. UJD submits the Government each year the Report on Safety of Nuclear Installations and the Management of Spent Nuclear Fuel and RAW in the Slovak Republic
This report documents the proceedings from the 'Workshop on New Reactor Siting, Licensing and Construction Experience', held in Prague, Czech Republic on 15-17 September 2010. A total of 59 specialists from 16 countries and international organisations attended. The Meeting was sponsored by the OECD Nuclear Energy Agency Committee on Nuclear Regulatory Activities and hosted by the State Office for Nuclear Safety (SUJB) in Czech Republic. The objectives of the workshop were to review and discuss recent and past construction experience lessons learned including perspectives from regulatory authorities, as well as vendors, and licensee. The workshop addressed issues associated with project management resources including: a) overall human resources, expertise, experience and organisation available to the licensee, b) capability of each potential vendor (in-house knowledge and skills versus planned subcontracting and subcontractor management). The workshop also discussed the lessons learned in the regulation of site selection, evaluation and site preparation as well as the review of regulatory practices for the licensing of new reactors, including the regulatory body infrastructure, staffing and expertise needed. The workshop provided an excellent opportunity to communicate recent experience on these topics to a wider audience, including participants from OECD member countries as well as New Entrants from non-OECD member countries. The workshop allowed the WGRNR group to introduce and discuss the current programme of work and products under development in order to gain insights from workshop participants on each of the programme of work areas, and get feedback on additional focus areas. The workshop was structured in 4 technical sessions, each followed by ample time for panel discussions. The first technical session was devoted to presentations of the licensing process for new reactors followed by different member countries. The second technical session was
production companies have initiated uranium exploration to increase resources associated with current operations and to confirm the potential of other known deposits and regional exploration trends. Niger exports all of its uranium so market price and project economics are important factors to its uranium industry. By contrast, all of India's uranium production is dedicated to its domestic nuclear power programme. Though uranium production is less sensitive to production economics, India is nevertheless emphasizing exploration in geologic environments that have the potential to host large, high-grade deposits with the potential for lower production costs. To ensure self-sufficiency in the near term, India is also developing new production capability in a variety of geologic environments with well-established resources, but with lower grades and capacity potential. The recent market price increase has made projected production costs for two of Argentina's uranium projects more competitive in the marketplace. Before re-starting existing projects or developing new projects, however, Argentina's production company, CNEA, must acquire a number of mining permits and licenses. To ensure that its projects gain public and regulatory approval, CNEA has implemented programmes that emphasize technology that will ensure that its proposed operations meet regulatory requirements. It has also initiated a public relations programme to demonstrate the environmental compatibility of its projects to affected communities. Uranium mining and processing and site rehabilitation in the Czech Republic are closely monitored by the State Office for Nuclear Safety (SUJB). The oversight responsibilities of SUJB and the body of law that ensures its authority are presented in paper that may be useful to countries with emerging nuclear industries. Approximately 80% of China's uranium resource base is hosted in hard rock geologic environments, mainly in vein deposits in granites and volcanic complexes. These
indicator for the Collective Effective Dose of Dukovany NPP has shown exceptionally good results in comparison with other Pressurized Water Reactors (PWRs) and Water-Water Energetic Reactors (VVERs). During the past three years, the value was less than 0.15 manSv per Unit; and A comprehensive station blackout simulator scenario has been developed and implemented for several years at the plant. The scenario involves multiple off-site agencies and has a high degree of realism. It is used to practise and improve response times for power restoration activities and familiarize off-site personnel with nuclear safety principles. The team has also made recommendations and suggestions related to areas where the operational safety of the Dukovany NPP could be improved. Examples include: Improving the effectiveness of using its root cause analysis method to prevent the repetition of events; Clarifying and reinforcing expectations regarding the use of error prevention tools and enhancing their application; and Ensuring adequate protection of emergency workers and evacuees following a possible radioactive release. The plant's management expressed a determination to address all the areas identified for improvement and requested that the IAEA schedule a follow-up mission in approximately 18 months. The team handed over a draft of their recommendations, suggestions and good practices to the plant management in the form of ''Technical Notes'' for factual comments. The technical notes will be reviewed at the IAEA headquarters, including any comments from Dukovany NPP and the Czech regulatory body, the State Office for Nuclear Safety (SUJB). The final report will be submitted to the Government of the Czech Republic within three months. This was the 162nd mission of the OSART programme, which began in 1982. Video and photos are available from the OSART Mission. General information about OSART missions can be found on the IAEA Website. (IAEA)
Power Plant has a Technical Support Centre Manual to establish the decision-making process necessary to support the Control Room Crew in implementing Emergency Operating Procedures. The team identified a number of proposals for improvements in operational safety at Temelin Nuclear Power Station. Examples include the following: - Management and Plant staff should improve their practices to enable more efficient reporting of minor deficiencies; - Power Plant operators should improve their adherence to existing human error prevention procedures; and - The Power Plant has underway too many temporary modifications to the plant systems, many of which have no specific schedule for completion and could have adverse implications for safety. Temelin management expressed a determination to address all the areas identified for improvement and requested the IAEA to schedule a follow-up mission in approximately 18 months. The team delivered a draft of its recommendations, suggestions and good practices to the plant management in the form of ''Technical Notes'' for factual comments. These notes will be reviewed at IAEA headquarters, including any comments from Temelin Nuclear Power Station and the Czech Republic regulatory body SUJB. The final report will be submitted to the Government of the Czech Republic within three months. This was the 172th mission of the OSART programme, which began in 1982. General information about OSART missions can be found on the IAEA Website. Background The IAEA Nuclear Safety Action Plan defines a programme of work to strengthen the nuclear safety framework worldwide in the light of the Fukushima Daiichi Nuclear Power Plant accident. The plan was unanimously endorsed by IAEA Member States during the Agency's 55th General Conference in September 2011. The Action Plan recommended: ''Each Member State with nuclear power plants to voluntarily host at least one IAEA Operational Safety Review Team (OSART) mission during the coming three years, with the initial
The OECD Workshop on Licensing and Operating Experience of Computer-Based I and C Systems, was sponsored by both the Committee on Nuclear Regulatory Activities (CNRA) and the Committee on the Safety of Nuclear Installations (CSNI) of the OECD Nuclear Energy Agency (NEA). It was organised in collaboration with the Czech State Office for Nuclear Safety (SUJB), the Czech Power Board CEZ a.s., I and C Energo a.s. and the Nuclear Research Institute, Rez near Prague. The objectives of the Workshop were to exchange the experience gained by both the regulators and the industry in different countries in the licensing and operation of computer-based I and C systems, to discuss the existing differences in their licensing approaches in various countries, to consider the safety aspects of their practical use, and to discuss the ways of promoting future international co-operation in the given area. The scope of the Workshop included: - review of the progress made since the CNRA/CSNI workshop which was held in 1996 - current and future regulatory needs and/or requirements for the computer-based I and C systems - progress made in software life cycle activities, including verification and validation, and safety/hazards analysis - benefits of applying the computer-based I and C systems to improve plant performance and safety. The Technical Sessions and Discussion Sessions covered the following topics: Opening Session: Advances made in the use and planning of computer-based I and C systems; Topic 1: National and international standards and guides for computer-based safety systems; Topic 2: Regulatory aspects; Topic 3: Analysis and assessment of digital I and C systems; Topic 4: Software life cycle activities; Topic 4: Experience with applications, system aspects, potential limits and future trends and needs; Final Session: Workshop summary. The workshop provided a unique opportunity for people with experience in licensing, developing, manufacturing, implementing, maintaining or
. ''We wanted to focus on the organizational and human side rather than the technology.'' The review covered aspects related to corporate management, independent oversight, human resources, communication, maintenance, technical support and procurement. The conclusions of the review are based on the IAEA's Safety Standards. The OSART team identified good corporate practices, which will be shared with the rest of the nuclear industry for consideration of their possible application elsewhere. The team also identified proposals for improvements of corporate processes and performance important to the operational safety of NPPs. CEZ management expressed a commitment to address all the areas identified for improvement and requested the IAEA to schedule a follow-up mission in approximately 18 months' time. The team provided a draft of their proposed recommendations and good practices to the CEZ management in the form of Technical Notes for factual comments, which will be reviewed at the IAEA's headquarters including comments from CEZ and the Czech Republic Safety Authority (SUJB). The final report will be submitted to the Government of the Czech Republic within three months. This was the 176th mission of the OSART programme, and the eighth in the Czech Republic. Background: General information about OSART missions can be found on the IAEA Website. An OSART mission is designed as a review of programmes and activities essential to operational safety. It is not a regulatory inspection, nor is it a design review or a substitute for an exhaustive assessment of the plant's overall safety status. Experts participating in the IAEA's June 2010 International Conference on Operational Safety of Nuclear Power Plants (NPP) reviewed the experience of the OSART programme and concluded: In OSART missions NPPs are assessed against IAEA Safety Standards which reflect the current international consensus on what constitutes a high level of safety; and OSART recommendations and suggestions are of
pursuant to Act No 211/2000 of Coll. was published on UJD web site (www.ujd.gov.sk). From January 2001, 56 requests were registered asking for the information (by phone, e-mail, letter or personally). One written request from Greenpeace was not satisfied since the information is a matter of business secret. The matter is in the proceeding of the Supreme Court of the Slovak Republic. The Slovak press agencies, daily newspapers and electronic media were provided with 63 contributions on domestic and foreign UJD activities. UJD, together with SUJB, issues the expert journal 'Bezpecnost jadrovej energetiky (Nuclear Sector Safety)'. Two important articles on UJD legislative activities and on informing the public were published in monthly 'Verejna sprava (Public Administration)'. Contributions on supervisory activity and on UJD international co-operation are published regularly in 'Spravodajstvo SE (SE Information Service)', company journals 'Mochovce' and 'Bohunice'. Domestic and foreign UJD activities were presented in 5 issues of 'Bulletin Slovenskej nuklearnej spolocnosti (Slovak Nuclear Society Bulletin)'. This year, the report on nuclear facilities safety and on handling with spent nuclear fuel and radioactive waste in the Slovak Republic was published in European Nuclear Society journal 'Nuclear Europe Worldscan No 7-8/2001'. Several important contributions were published in journal 'Energia (Energy)'. Contributions on UJD tasks and mission in the Slovak Republic were published in 'Energia almanach (Energy Almanac 2001/2002)' and in 'Euro Nuclear'. Three contributions on domestic and foreign UJD activities were prepared for the world information Agency NucNet. Slovak-English additional information document on UJD was elaborated and issued for the public in December 2001. The 2001 Yearbook on UJD activities and on nuclear facilities safety in the Slovak Republic was prepared and issued in Slovak and English version. Four press conferences took place in 2001 in UJD followed
The Nuclear Regulatory Authority of the Slovak Republic (UJD) is around to serve the public. This is a regulatory institution that furnishes truthful and independent information on nuclear safety of nuclear installations, including information on management of radioactive wastes, spent fuel, nuclear materials, control and record-keeping thereof, as well as information on other fuel cycle phases. UJD seeks to provide information in an orderly, accurate and comprehensible manner in such a way that it cannot be disclaimed, as the public has the right to know the truth. In formulating information, regularity, consistency and openness are of high importance, because information presented cannot serve a controversy. UJD furnishes information independently and separately from that issued by nuclear power plant operators. As a central administration authority, UJD provides on request, within the field of its responsibility, in particular the information on safety of nuclear energy installations independently from nuclear programme implementers, allowing the public and the media to check up the data and information thereon. A significant element of the information is the demonstration that the area of nuclear energy uses in the Slovak Republic has its binding rules and the compliance therewith is controlled by the state through an independent institution - UJD. As early as in 1995 the foundations laid were at UJD for the concept for broad public information on UJD activity and on safety of nuclear installations by opening UJD Information Centre. This Centre provides communication with the public and the media, thereby contributing to fashioning among the public a favourable image of the independent state supervision over nuclear safety. The Information Centre was extended in 2000. In 2000, 76 contributions on domestic and foreign UJD activities were sent in to Slovak press agencies, dailies and electronic media. UJD is together with the SUJB the publisher of the journal
