2001-01-01

The French energy commission (CEA) has defined 3 axis of development in the framework of a 4 year contract with the government. The first axis is to propose technological solutions for improving competitiveness of nuclear energy, for managing nuclear wastes and for assuring safety at any step of the nuclear industry. The second axis concerns promoting new technologies in the fields of energy, of information and of bio-engineering. CEA will develop studies about the use of hydrogen as an alternative energy for transport. The third axis deals more particularly with fundamental research in the fields of energy, of environment, of bio-technologies and of health (research about the prion for instance). The subsidy given by the state has been increased by 3.4% for 2001. (A.C.)

The Cea a public research institution was re-classified among the energy research establishments (11 december 2008). The Cea, as the result of exceptional circumstances and complex activities, is today entering into a new era and must confront many national and supranational challenges. It is preparing, in effect, for a future nuclear industry (safer, less polluting, non-proliferating and more economical) and is conducting research into other energy solutions within the framework of sustainable development and limited greenhouse gas effects (hydrogen technology, fusion, alternative energy technologies). It also has another goal, to make technological research available to industry, not only by developing micro and nano-technologies or even to contribute technology for the benefit of scientific knowledge of living creatures, matter, climate and the environment. The new classification of the Cea as a research establishment in the field of energy, a heading which includes three other entities (A.N.D.R.A., A.D.E.M.E. and I.F.P.), raises questions about its specialization and diversification. However, no substantive change was made to the drafting of the legislative provisions so it is possible to imagine that the Cea takes initiatives in other fields, at the instigation or with the approval of the government, a matter which is facilitated by its classification in the E.P.I.C. category (public establishment at industrial and commercial character). The Cea also represents France in international organisations in the nuclear sector, such as the OECD Nuclear energy agency (Nea), the International atomic energy agency (IAEA) and the European communities. It also participates in intergovernmental negotiations in the nuclear field and ensures any follow-up required with regard to any resulting agreements. today, the Cea plays a major role in the implementation of French nuclear policy with the aim of making available to countries wishing to develop nuclear energy, a framework

A brief account is given of the way in which nuclear energy has developed in France and elsewhere over the last fifty years: options developed by the French Atomic Energy Commission (CEA), naval propulsion, development of pressurised water reactors, MOX and thorium fuels. Afterwards, the prospectives for the 21. century will be discussed. Considering that natural resources are depleting while releases of both greenhouse gases and world population are increasing, an active energy policy will have to be implemented with due consideration for social equity and solidarity. It is in this context that the developed countries will have to give preference, beyond savings, to renewable sources of energy, including of course, nuclear energy. Nuclear energy can continue to develop in the long term, provided fast breeder technology is developed at some point. As far as transport is concerned, hydrogen technology, which is clean and renewable, is promising, provided it is generated by nuclear energy. (author)

2009-01-01

This paper describes a tool called 'Numerical Platon' developed by the French Atomic Energy Commission (CEA). It provides a freely available (GNU LGPL license) interface for coupling scientific computing applications to various freeware linear solver libraries (essentially PETSc, SuperLU and HyPre), together with some proprietary CEA solvers, for high-performance computers that may be used in industrial software written in various programming languages. This tool was developed as part of considerable efforts by the CEA Nuclear Energy Division in the past years to promote massively parallel software and on-shelf parallel tools to help develop new generation simulation codes. After the presentation of the package architecture and the available algorithms, we show examples of how Numerical Platon is used in sequential and parallel CEA codes. Comparing with in-house solvers, the gain in terms of increases in computation capacities or in terms of parallel performances is notable, without considerable extra development cost

Dismantling at the CEA's Nuclear Energy Division: strategy and programmes

International Nuclear Information System (INIS)

Lecomte, C.; Prunele, D. de; Rozain, J.P.; Nokhamzon, J.G.; Tallec, M.

2008-01-01

The CEA's Nuclear Energy Division (DEN) nuclear facilities currently include seventeen reactors and thirty six other miscellaneous facilities, particularly laboratories, fuel processing units and facilities specific to waste management. Some of these are currently being dismantled or must be dismantled soon so that the DEN, the Nuclear Energy Division, can construct new equipment and thus have available a range of R and D facilities in line with the issues of the nuclear industry of the future. At CEA, the first nuclear facility dismantling operations go back several dozen years and involve numerous and varied facilities. The first operations of any significance took place in the 1960's and 1970's and covered, for example, the first plutonium plant at Fontenay-aux-Roses (total dismantling) and small research reactors or critical models - CESAR and PEGGY at Cadarache and MINERVE at Fontenay-aux Roses (civil engineering cleaned up and kept). At La Hague, the dismantling of AT1, a pilot workshop used by the CEA during the 1970's to process irradiated fuels from fast neutron reactors, was completed in March 2001 (IAEA former stage 3, excluding civil engineering demolition). On the other hand, during this period of first dismantling, the intermediate-sized reactors (G1, Rapsodie) were only partially dismantled after shut down, mainly due to the lack of graphite and sodium waste management routes at the time. About twenty facilities were thus dealt with up to 2001, in other words about half of all the nuclear facilities shut down permanently before this date. (authors)

1995-01-01

Central in the infrastructure through which France obtains some 80% of its electric power from nuclear energy stands the French Atomic Energy Authority (Commissariat à l'Energie Atomique - CEA). This year the CEA celebrates its Golden Jubilee. Mastery of nuclear energy goes hand-in-hand with fundamental research in the fields of nuclear and sub-nuclear physics, and the founders of the CEA, like F. Joliot and F. Perrin, considered it essential to relaunch fundamental research in France after the Second World War. In particular, A. Messiah's courses on quantum mechanics made a considerable contribution to the re-establishment of a French school of atomic and sub-atomic physics. As the CEA expanded and nuclear industry grew up, the need was shown for close links between fundamental research and its applications. In addition, the CEA realized how important it was to become a part of the national and international scientific community as highly effective cooperation was developing. The CEA has drawn a wealth of scientific, cultural and intellectual benefits from its collaboration with CERN. During the same period, as fundamental particle physics research has been making spectacular progress, its requirements have grown commensurately. It is not therefore surprising that CERN needs partners capable of bringing together the domains of fundamental research and major equipment and of promoting a dialogue between research and industry. As was pointed out by Jacques Haissinski, head of the Department of Astrophysics, Particle Physics, Nuclear Physics and Associated Instruments (DAPNIA), the CEA, set up to develop major programmes for applying nuclear processes, is particularly well equipped to design, build and operate the huge instruments for exploring the infinitely small and the infinitely large. Tomorrow's nuclear industry needs and will continue to need fundamental research, with its openness and its cooperation. Particle physics needs and will continue

The opening of the CEA to the general public

International Nuclear Information System (INIS)

Deloche, Robert

1999-01-01

Full text: The relationships between science and society have evolved considerably over the past years, just like the perception of the nuclear industry in the French public opinion. Recent psychosociological surveys show that only half of the French population is familiar with the CEA and that the public would like to obtain new elements of judgment in order to be able to develop a direct appreciation of the activities of a research organization such as the Atomic Energy Commission. It is essential to meet the public's expectations, to keep it properly informed of the CEA's research activities, and to help it understand the relevance of the results obtained and the solutions offered to decision-makers, i.e. industrialists and public authorities. One way to answer the public opinion's questions and to meet its expectations is to allow a rowing number of visitors to see who we are, what we study in our laboratories, and how we work to contribute to scientific progress and to the diffusion of technology, in a manner that is useful to society as a whole. This describes the spirit and the objective that governed the very idea and elaboration of the program entitled 'Opening of the CEA to the general public'. This operation consists not only in having communication specialists guide visitors throughout the facilities and equipment of the CEA, but also in encouraging researchers and groups of visitors to meet in the laboratories. A 'CEA - communication' network is under construction. It already has nearly 600 members. Communication is considered to be a real calling that falls within the scope of the CEA's strategy, and the work accomplished in this respect is recognized to the same extent as research. To this end, a charter for the CEA - communication network will be signed by every contributor and manager. A training scheme focused on public speaking and scientific vulgarization was initiated. 50 members of the network have already been trained, and 250 will be in 1999

With PWR reactors, CEA has applied a large part of its activities on steam generators, whilst other technical studies have involved components, maintenance, thermo-hydraulics, safety, materials, instrumentation apparatus and controls. For small light-water reactors, studies carried out have led to development of the Thermos Project: demonstrating the validity of urban heating derived from a pool-type reactor. Other studies have involved fast reactors (manufacture of fissile fuel assemblies, contributions toward the development of the Superphenix project and longer-term studies involving the overall breeder line). Finally, studies on the retreatment of irradiated fuels: aside from the retreatment of irradiated fuel programmes, CEA is pursuing its work on the TOR Project (large-scale pilot for retreatment of fast-neutron fuels) [fr

Characterization and consequences from CEA nuclear fuel cycle facilities effluents releases - 1995 up to 2007 period

International Nuclear Information System (INIS)

Ferreira, Nelson Luiz Dias; Fonseca, Lizandra Pereira de Souza

2009-01-01

Discharges to the environment of airborne and/or liquid radioactive effluents from the normal operation of nuclear facilities can become a potential source of radiation exposure to humans. The highest exposed members of the public are defined as the critical group. The requirements for the control and monitoring of radioactive discharges to the environment and the degree of environmental monitoring required are linked to the assessed critical group dose. The assessed dose can be compared to dose constraint, which is a fraction of the annual effective dose to members of the public, as well as the level of exemption specified by the National Commission for Nuclear Energy (CNEN). Effluents releases from the Centro Experimental Aramar (CEA) facilities are registered and described at CEA Effluent Report, semestrally sent to CNEN. Basically, that report provides information related to the type and the quantity of chemical and radioactive substances released to the environment due the routine operation of CEA nuclear fuel cycle facilities (LEI - Isotopic Enrichment Laboratory, USIDE - Pilot Plant for Industrial Verification of Uranium Enrichment and LABMAT - Nuclear Materials Laboratory). CEA Annual Effluent Report includes assessment of the annual effective doses for members of the critical group for the CEA site. This work presents the characterization of the radioactive release source terms and a historical of the critical group annual doses from 1995 up to 2007. (author)

The CEA is tasked with carrying out certain research activities: within the Military Applications Division (DAM), research is focused on the nuclear deterrence and, within the Nuclear Energy Division, on developing the industrial nuclear systems of the future and optimising existing nuclear systems in partnership with EDF and AREVA. These major research and development themes entail a need for nuclear research and support facilities which must be maintained at a high level of performance and safety and, also, constantly upgraded to handle the research activities and programmes for which they are used. The CEA strategy is based on the right packaging of the radioactive liquid or solid waste into a form required for its transport, storage or disposal. The Caraibes software allows an efficient traceability of the waste packages. Most of the radioactive effluent processing stations of CEA are being upgraded

2012-12-27

In July 2010, the U.S. Department of Energy (DOE) awarded funding to PECI to develop training curriculum in commercial energy auditing and building commissioning. This program was created in response to the high demand for auditing and commissioning services in the U.S. commercial buildings market and to bridge gaps and barriers in existing training programs. Obstacles addressed included: lack of focus on entry level candidates; prohibitive cost and time required for training; lack of hands-on training; trainings that focus on certifications & process overviews; and lack of comprehensive training. PECI organized several other industry players to create a co-funded project sponsored by DOE, PECI, New York State Energy and Research Development Authority (NYSERDA), California Energy Commission (CEC), Northwest Energy Efficiency Alliance (NEEA) and California Commissioning Collaborative (CCC). After awarded, PECI teamed with another DOE awardee, New Jersey Institute of Technology (NJIT), to work collaboratively to create one comprehensive program featuring two training tracks. NJIT’s Center for Building Knowledge is a research and training institute affiliated with the College of Architecture and Design, and provided e-learning and video enhancements. This project designed and developed two training programs with a comprehensive, energy-focused curriculum to prepare new entrants to become energy auditors or commissioning authorities (CxAs). The following are the key elements of the developed trainings, which is depicted graphically in Figure 1: • Online classes are self-paced, and can be completed anywhere, any time • Commissioning Authority track includes 3 online modules made up of 24 courses delivered in 104 individual lessons, followed by a 40 hour hands-on lab. Total time required is between 75 and 100 hours, depending on the pace of the independent learner. • Energy Auditor track includes 3 online modules made up of 18 courses delivered in 72 individual

Donie, Ph.; Kimmel, D.; Launay, R.

2002-09-01

This document presents the MOSAR method (systemic organized method of risk analysis) developed by the French atomic energy commission (CEA) for the carrying out of 'a priori' (before any accident occurrence) risk analyses. The objective of the method is to look for technical and operational malfunctions in a facility or in a process and in a defined environment. The MOSAR method is based both on a systemic approach and on the analysis of all potential sources of danger intrinsic to the system. The aim of this document is: to recall the principles of the method, to present its tools in a standardized way, to give some application rules for a pragmatic and progressive approach based on validated data, and to show in conclusion the different types of application using a consistent approach.

After having indicated locations of French nuclear installations which are currently being dismantled (about 30 installations), and recalled the different categories of radioactive wastes with respect to their activity level and the associated storage options, this article gives an overview of various aspects of dismantling, more precisely in the case of installations owned and managed by the CEA. These operations comprise the dismantling itself, the recovery and packaging of wastes, old effluents and spent fuels. The organisation and responsible departments within the CEA are presented, and the author outlines some operational problematic issues met due to the age of installations (traceability of activities, regulation evolutions). The issue of financing is then discussed, and its uncertainties are outlined. The dismantling strategy within the CEA-DEN is described, with reference to legal and regulatory frameworks. The next parts of the article address the organisation and the economic impact of these decontamination and dismantling activities within the CEA-DEN, highlight how R and D and advanced technology are a support to this activities as R and D actions address all scientific and technical fields of nuclear decontamination and dismantling. An overview of three important dismantling works is proposed: Fontenay-aux-Roses, the Marcoule CEA centre (a reference centre in the field of nuclear dismantling and decontamination) and the Grenoble CEA centre (reconversion in R and D activities in the fields of technologies of information, of communication, technologies, for health, and in renewable energies). The last part addresses the participation to the Strategic Committee of the Nuclear Sector (CSFN)

Restructuring the Energy System. Report of the Energy Commission

International Nuclear Information System (INIS)

1995-01-01

The commission was instructed to examine the current energy policy programs for restructuring and developing the energy system (i.e. phasing out nuclear power and moving to renewable sources) and to analyze the needs for changes; to propose measures for ensuring an efficient electricity supply under the new conditions of a liberalized electricity market; and to present proposals for a schedule for reorganizing the energy system. The report gives a full picture of the Swedish energy system including supply, consumption, prices, environmental impacts, R and D, and international aspects. The commission concludes that one nuclear power plant can be closed during the 1990's without upsetting the power balances. Phasing out all nuclear plants by year 2010 will create problems with the price levels of electricity supply, and will conflict with the CO 2 reduction objective. The proposals for economic control measures for performing the restructuring include: An environmental bonus (or investment support) for environmentally sound electricity production financed by an electricity tax, a tax on nuclear power increasing with the age of the reactors, a reorganization fund to finance new and environmentally acceptable electricity production. Also, energy research should be allotted greater resources, in particular for new technology for electricity production. The commission points towards the possibilities for reducing energy consumption, and especially electricity consumption. Space heating should gradually move away from electric heating. Examples are given on measures for improving energy efficiency and problems with financing such measures should be studied

Experimental programs in the United States and France have followed similar paths in supplying much of the data needed to analyze severe accidents. Both the HI/VI program, conducted at the Oak Ridge National Laboratory (ORNL) under the sponsorship of the U. S. Nuclear Regulatory Commission (NRC), and the HEVA/VERCORS program, supported by IPSN-Commissariat a l`Energie Atomique (CEA) and carried out at the Centre d`Etudes Nucleaires de Grenoble, have studied fission product release from light water reactor (LWR) fuel samples during test sequences representative of severe accidents. Recognizing that more accurate data, i.e., a better defined source term, could reduce the safety margins included in the rather conservative source terms originating from WASH-1400, the primary objective of these programs has been to improve the data base concerning fission product release and behavior at high temperatures. To facilitate the comparison, a model based on fission product diffusion mechanisms that was developed at ORNL and adapted with CEA experimental data is proposed. This CEA model is compared with the ORNL experimental data in a blind test. The two experimental programs used similar techniques in out-of-pile studies. Highly irradiated fuel samples were heated in radiofrequency induction furnaces to very high temperatures (up to 2700 K at ORNL and 2750 K at CEA) in oxidizing (H{sub 2}O), reducing (H{sub 2}) or mixed (H{sub 2}O+H{sub 2}) environments. The experimental parameters, which were chosen from calculated accident scenarios, did not duplicate specific accidents, but rather emphasized careful control of test conditions to facilitate extrapolation of the results to a wide variety of accident situations. This paper presents a broad and consistent database from ORNL and CEA release results obtained independently since the early 1980`S. A comparison of CORSOR and CORSOR Booth calculations, currently used in safety analysis, and the experimental results is presented and

CEA - Nuclear Energy Division. Report on Sustainable Radioactive Waste Management

International Nuclear Information System (INIS)

2012-12-01

The Sustainable Radioactive Waste Management Act of June 28, 2006, specified clear guidelines for spent nuclear fuel management. It states two complementary principles: - The policy of treating and recycling spent nuclear fuel is valid for reducing the quantity and toxicity of suitably packaged ultimate radioactive waste-forms. - The reference process for high-activity and long-lived ultimate waste is deep geological disposal. The report prepared by the CEA in response to these requirements was completed after several years of work in cooperation with the other French actors in this field (EDF, AREVA) and with contribution of the CNRS and Andra. It addresses the following topics in several volumes: n guidelines for research on 4. generation systems, and a description of the various systems examined; - the results of research coordinated by the CEA on partitioning and transmutation of long-lived radioactive elements; - choices proposed for the Astrid integrated technology demonstrator - a sodium-cooled fast reactor (SFR) - and a reasonable timetable for its construction; - a review of research conducted around the world on 4. generation systems based on fast neutron reactors (FNRs). The principal results and findings compiled by the CEA from these studies are summarized in this document

Ovarian and colonic CEA were compared immunologically by means of antisera prepared against each of them. CEAs of both origins were found identical by immunodiffusion methods. In radioimmunological experiments, slight differences were observed between some but not all ovarian CEAs and colonic CEAs and also between different preparations of colonic CEA: no organ specificity of ovarian CEA could be demonstrated. Finally, CEA level was measured in 41 sera of patients with ovarian carcinoma by two radioimmunoassays, one using colonic CEA as tracer and standard and anti-colonic CEA serum, the other using ovarian CEA and anti-ovarian CEA serum: the values given by the two assays were highly correlated (rsub(s) = 0.8107), meaning that an organ specific assay for ovarian CEA is not needed.

Carre, Frank; Anzieu, Pascal; Billot, Philippe; Brossard, Philippe; Fiorini, Gian-Luigi

2004-01-01

As a result of an early technology road-map performed at the end of 2000, the CEA selected a sequenced development of advanced gas cooled high temperature nuclear systems as main focus for its R and D programme on future nuclear energy systems. The selection of this research objectives originates both from the significance of fast neutrons and high temperature for nuclear energy to meet the needs anticipated beyond 2020/2030, and from the significant common R and D pathway that supports both medium term industrial projects and more advanced versions of gas cooled reactors. The first step of the 'Gas Technology Path' aims to support the development of a modular HTR likely to meet international market needs around 2020. The second step is a Very High Temperature Reactor (> 950 deg. C) to efficiently produce, among others, hydrogen though thermo-chemical water splitting or to generate electricity with an efficiency above 50%. The third step of the Path is a Gas Fast Reactor that features a fast-spectrum helium-cooled reactor and closed fuel cycle, with a direct-cycle helium turbine for electricity production and full recycle of actinides. The paper succinctly presents the R and D program launched in 2001 by the CEA with industrial partners on the 'Gas Technology Path', which is destined to become the contribution of France to the development of the VHTR and the GFR within the next phase of the Generation IV Forum

As part of the work scope set in the French law on high level long lived waste R&D passed in 1991, CEA is conducting a research program to establish the scientific basis and assess the feasibility of long term storage as an option for the safe management of nuclear waste for periods as long as centuries. This goal is a significant departure from the current industrial practice where storage facilities are usually built to last only a few decades. From a technical viewpoint such an extension in time seems feasible provided care and maintenance is exercised. Considering such long periods of time, the risk for Society of loosing oversight and control of such a facility is real, which triggers the question of whether and how long term storage safety can be actually achieved. Therefore CEA commissioned a study (1) in which MUTADIS Consultants (2) and CEPN (3) were both involved. The case study looks into several past and actual human enterprises conducted over significant periods o f time, one of them dating back to the end of the 18th century, and all identified out of the nuclear field. Then-prevailing societal behavior and organizational structures are screened out to show how they were or are still able to cope with similar oversight and control goals. As a result, the study group formulated a set of performance criteria relating to issues like responsibility, securing funds, legal and legislative implications, economic sustainable development, all being areas which are not traditionally considered as far as technical studies are concerned. These criteria can be most useful from the design stage onward, first in an attempt to define the facility construction and operating guiding principles, and thereafter to substantiate the safety case for long term storage and get geared to the public dialogue on that undertaking should it become a reality.

Carcinoembryonic Antigen is one of most frequently checked tumor markers in cancer management. We performed statistical analysis with serum CEA data of 2626 persons who received regular health examination and were thought to be free of active disease to determine the cutoff values of serum CEA level in normal Korean adults and to study the factors influencing serum CEA levels in normal subjects. 1) The cutoff values of serum CEA in normal Korean adults in general were 9.28 ng/ml for men, 5.90 ng/ml for women. 2) Serum CEA level was influenced by age, present smoking history, sex, and abnormal findings in chest X ray. 3) Serum CEA level had no correlation with the history of amount of alcohol consumption or obesity. 4) Cutoff values of serum CEA in normal Korean adults were tabulated according to age, sex, and smoking history. Serum CEA level was influenced by age, sex, present smoking history and abnormal findings in chest X ray and cutoff values of serum CEA were tabulated according to age, sex, and smoking history.

To investigate serum carcinoembryonic antigen (CEA) as a prognostic factor for rectal cancer patients receiving pre-operative chemoradiotherapy (CRT). Between 2000 and 2009, 138 patients with advanced rectal cancer receiving CRT before surgery at our hospital were retrospectively classified into 3 groups: pre-CRT CEA <6 ng/ml (group L; n = 87); pre-CRT CEA ≥ 6 ng/ml and post-CRT CEA <6 ng/ml (group H-L; n = 32); and both pre- and post-CRT CEA ≥ 6 ng/ml (group H-H; n = 19). CEA ratio (defined as post-CRT CEA divided by pre-CRT CEA), post-CRT CEA level and other factors were reviewed for prediction of pathologic complete response (pCR). Five-year disease-free survival (DFS) was better in groups L (69.0%) and H-L (74.5%) than in group H-H (44.9%) (p = 0.024). Pathologic complete response was observed in 19.5%, 21.9% and 5.3% of groups L, H-L and H-H respectively (p = 0.281). Multivariate analysis showed that ypN stage and pCR were independent prognostic factors for DFS and that post-CRT CEA level was independently predictive of pCR. As a whole, post-CRT CEA <2.61 ng/ml predicted pCR (sensitivity 76.0%; specificity 58.4%). For those with pre-CRT CEA ≥6 ng/ml, post-CRT CEA and CEA ratio both predicted pCR (sensitivity 87.5%, specificity 76.7%). In patients with pre-CRT serum CEA ≥6 ng/ml, those with “normalized” CEA levels after CRT may have similar DFS to those with “normal” (<6 ng/ml) pre-CRT values. Post-CRT CEA level is a predictor for pCR, especially in those with pre-CRT CEA ≥6 ng/ml

The PEP-II High Energy Ring (HER), a 9 GeV electron storage ring, has been in commissioning since spring 1997. Initial beam commissioning activities focused on systems checkout and commissioning and on determining the behavior of the machine systems at high beam currents. This phase culminated with the accumulation of 0.75 A of stored beam-sufficient to achieve design luminosity--in January 1998 after 3.5 months of beam time. Collisions with the 3 GeV positron beam of the Low Energy Ring (LER) were achieved in Summer of 1998. At high beam currents, collective instabilities have been seen. Since then, commissioning activities for the HER have shifted in focus towards characterization of the machine and a rigorous program to understand the machine and the beam dynamics is presently underway

1985-04-01

The determination of serum CEA (Sandwich method) and CEA staining (PAP method) of excised specimens were performed in patients with gastric or colorectal cancer, and the biological characteristics of each cancer and the factors to increase serum CEA were studied with the following results: As colonic cancer has strong CEA productivity, serum CEA can be useful for the detection of cancer, and especially effective for the postoperative observation. Gastric cancer has weak CEA productivity, and serum CEA is not so useful in the detection of cancer and the judgement of resectability. The CEA positive rate of tissue with CEA staining was 80% in gastric cancer, 100% in colonic cancer, and were nearly equal to the CEA positive rate of serum in the group of terminal stage. In the mode of CEA staining of cancerous cells, IV type was observed most frequently in gastric cancer, and I type in colonic cancer. Among the resected cases showing more than 7ng/ml serum CEA, differentiated type, lymph node metastasis (+), the degree of tissue staining with CEA staining, the mode of cell staining O or I type in gastric cancer and I type in colonic cancer were observed in common.

CEA annually produces about 3500 tons of radioactive wastes in its 43 basic nuclear installations. CEA ranks third behind EDF and Cogema. Low-level wastes (A wastes) are sent to ANDRA (national agency for the management of nuclear wastes)whereas medium-level wastes (B wastes) are stored by CEA itself. CEA has checked off its storing places and has set up an installation Cedra to process and store ancient and new nuclear wastes. 3 other installations are planned to operate within 6 years: Agate (Cadarache) will treat liquid effluents, Stella (Saclay) will process liquid wastes that are beta or gamma emitters, and Atena (Marcoule) will treat and store radioactive sodium coming from Phenix reactor and IPSN laboratories. The use of plasma torch for vitrifying wastes is detailed, the management of all the nuclear wastes produced by CEA laboratories and installations is presented. (A.C.)

Full text of publication follows: KROTOS facility has been operated by the European Commission at JRC-Ispra for many years until 1999 as part of the FARO/KROTOS programme. The programme had to be stopped at JRC due to new EC priorities, and an agreement was concluded with CEA to transfer the KROTOS facility and know-how to Cadarache to continue investigating the pending FCI issues. By this agreement, CEA became owner of the facility. The main objective of the KROTOS programme at CEA Cadarache is understanding the role of melt properties in steam explosion propagation and energetics and, in particular, steam explosion behaviour of prototypical corium melts. Possible influence of physicochemical processes on explosiveness will also be explored. Actually, analysis of alumina debris produced at Ispra have shown that formation of metastable phases and chemical reaction with water at high temperature may play a significant role in enhancing heat transfer to water in the explosion phase. In order to reach the objective, steam explosion experiments are performed in well characterised conditions for a large spectrum of conditions and melt compositions of interest for both in- and ex-vessel situations. A trigger is applied as a rule. Advanced technology and instrumentation is used to reduce uncertainties on initial conditions and characterise the various phases of an explosion, with emphasis on high energy X-ray cinematography to qualify pre-mixing. This advanced instrumentation will enable the measurement of detailed variables to consolidate the qualification of the FCI codes. The use of high energy X-rays made it necessary to construct a new building to house the facility and its components. The facility should newly become operative early 2005. Main improvements with respect to Ispra concern melt delivery, hydrogen measurement and X-ray imaging. Preliminary studies have demonstrated that identification of the pre-mixture-water interface and coherent melt jet core, and

Third single energy market package of the EU Commission

International Nuclear Information System (INIS)

Heller, W.

2008-01-01

In adopting the so-called Third Single Energy Market Package on September 9, 2007, the European Commission has initiated a comprehensive reform of the single energy market. The main item of the package is the separation of generation and supply from the transmission grids and transport networks in the electricity and gas sectors (ownership unbundling), an approach favored by the Commission. On the other hand, the Commission wants to advance protection of the European market in case firms from third countries, to the extent in which they do not comply with the EU unbundling requirements, would want to assume control over an EU grid or network. The key points of the package are presented. The legal and entrepreneurial ramifications are discussed, for instance, under the aspect of protection of ownership, and concrete as well as potential concerns about ownership unbundling are voiced.

Highlights: ► Demonstrated monitoring-based HVAC commissioning using an existing office building. ► Diagnosed various types of faulty operation in the HVAC system by trend data analyses. ► Identified a list of energy saving measures for the HVAC system. ► Quantified energy saving potential for each commissioning measure using calibrated energy simulation model. ► Achieved an actual energy saving of 10% after the implementations of cost-effective measures. -- Abstract: The performance of Heating, Ventilation and Air Conditioning (HVAC) systems may fail to satisfy design expectations due to improper equipment installation, equipment degradation, sensor failures, or incorrect control sequences. Commissioning identifies and implements cost-effective operational and maintenance measures in buildings to bring them up to the design intent or optimum operation. An existing office building is used as a case study to demonstrate the process of commissioning. Building energy benchmarking tools are applied to evaluate the energy performance for screening opportunities at the whole building level. A large natural gas saving potential was indicated by the building benchmarking results. Faulty operations in the HVAC systems, such as improper operations of air-side economizers, simultaneous heating and cooling, and ineffective optimal start, were identified through trend data analyses and functional testing. The energy saving potential for each commissioning measure is quantified with a calibrated building simulation model. An actual energy saving of 10% was realized after the implementations of cost-effective measures.

Aiming at radioimmunodetection of colorectal cancer, anti-CEA monoclonal antibodies (CEA102) were produced by immunization with purified CEA. CEA102 showed high specificity with clorectal cancer by mixed hemadsorption assay and immunoperoxidase technique. The antigen detected by CEA102 was confirmed to be carcinoembryonic antigen (CEA) and its molecular weight was estimated to be ca. 180,000 by biochemical analysis. The in vivo study using nude mice grafted a human colorectal cancer or a human malignant melanoma showed greater accumulation of 125 I-labeled CEA102 in CEA-positive colorectal cancer than in nude mouse tissues and CEA-negative malignant melanoma. Moreover we successfully obtained scans with good localization of the grafted colorectal cancer on FCR (Fuji Computed Radiography). Using 131 I-labeled CEA102 liver metastasis in the patient with colorectal cancer was successfully detected by external scanning with γ-camera. These results suggest that radiolabeled CEA102 is useful for the detection of colorectal cancer. (author)

The Commissariat a l'Energie Atomique has developed original methods and techniques for testing delicate components of the primary circuit of pressure water reactors. These techniques make use of a very wide range of non destructive testing methods: Eddy currents, particularly multiple frequencies, for testing steam generator tubes, gudgeon and other pins focused ultrasonics for testing all the welds of the reactor vessel and its cover plate, mixed welds of steam vessels and generators, low welds of the pressurizer and gudgeon pins from the inside. On site use is effected with specific machines intended either for inspecting the tube bundles of steam generators under the responsibility of INTERCONTROLE Co., or for the complete examination of the reactor vessel by mixed CEA/INTERCONTROLE crews under the responsibility of the CEA. All these operations are subjected to a programme of quality assurance that provides the guaranty of execution complying with the procedures in force [fr

Dumesnil, J.; Malvache, P.; Hugon, F.C.; Sollacaro, M.

2006-01-01

CEA's (French Atomic Energy Agency) packaging fleet is dedicated to transportation of test irradiated fuels, of research reactors fuels, of navy propulsion fuels, and of waste coming from and to nuclear plants or facilities. This fleet encompasses more than 30 types of casks ranging from 5 to 30 tons, with either recent designs or other dating back to the seventies. A study has been launched in order to perform a global analysis of the life expectancy of the existing CEA and COGEMA Logistics cask fleets with respect to a 2015 target, in order to anticipate its renewal, while limiting the number of type of cask. Key elements like periodical evolutions of design and transport regulations, lessons learnt of existing casks (design, approval and extensions, operational feedback, maintenance and dismantling) are taken into account in order to ensure compliance and availability of the fleet. Moreover, from design to cask delivery, including regulatory tests, safety analysis report/ CoC, and manufacturing, 3 to 5 years is needed. Therefore cask development should be taken into account earlier of invest and research's programs. The paper will address the current life expectancy study of CEA and COGEMA Logistics packaging fleet, based on lessons learnt and regulation evolution and on general R and D plans by user facilities. It will show how a comprehensive optimized fleet is made available to CEA and other customers. Such a fleet combines optimized investment and uses, thus entailing synergies for well-mastered costs of transports. (authors)

The directed radiotherapy of the solid tumors with fragments recombinants of radiolabelled antibodies is a topic of current investigation, so much at preclinical level as clinical. This work describes the preclinical characterization of a new fragment type diabody of the AcMo ior CEA1 that has been labelled with 131 I for their use in the diagnosis and the therapy of CEA positive tumors. The radiolabelling methodology used allows the incorporation of more than 90% of the radio iodine to the molecule without committing the capacity of recognition of its antigen significantly. The combination of the favourable properties pharmacy kinetic and high selective accumulation in the tumor, they make of the diabody anti CEA an appropriate candidate for the radioimmunodiagnosis and the radioimmunotherapy of tumors that expresses CEA (Author)

Lallement, JB; Posocco, PA

2012-01-01

Linac4 is a new 160 MeV linear accelerator for negative Hydrogen ions (H-) presently under construction which will replace the 50 MeV proton Linac2 as injector for the CERN proton accelerator complex. Linac4 is 80 meters long and comprises a Low Energy Beam Transport line, a 3 MeV RFQ, a MEBT, a 50 MeV DTL, a 100 MeV CCDTL and a PIMS up to 160 MeV. The commissioning of the Linac is scheduled to start in 2013. It will be divided into several steps corresponding to the commissioning of the different accelerating structures. A temporary measurement bench will be dedicated to the high energy commissioning from 30 to 100 MeV (DTL tanks 2 and 3, and CCDTL). The commissioning of the PIMS will be done using the permanent equipment installed in between the end of the Linac and the main dump. This note describes the technique we will use for reconstructing the transverse emittances and the expected results.

Growth curves and sustained commissioning modelling of renewable energy: Investigating resource constraints for wind energy

International Nuclear Information System (INIS)

Davidsson, Simon; Grandell, Leena; Wachtmeister, Henrik; Höök, Mikael

2014-01-01

Several recent studies have proposed fast transitions to energy systems based on renewable energy technology. Many of them dismiss potential physical constraints and issues with natural resource supply, and do not consider the growth rates of the individual technologies needed or how the energy systems are to be sustained over longer time frames. A case study is presented modelling potential growth rates of the wind energy required to reach installed capacities proposed in other studies, taking into account the expected service life of wind turbines. A sustained commissioning model is proposed as a theoretical foundation for analysing reasonable growth patterns for technologies that can be sustained in the future. The annual installation and related resource requirements to reach proposed wind capacity are quantified and it is concluded that these factors should be considered when assessing the feasibility, and even the sustainability, of fast energy transitions. Even a sustained commissioning scenario would require significant resource flows, for the transition as well as for sustaining the system, indefinitely. Recent studies that claim there are no potential natural resource barriers or other physical constraints to fast transitions to renewable energy appear inadequate in ruling out these concerns. - Highlights: • Growth rates and service life is important when evaluating energy transitions. • A sustained commissioning model is suggested for analysing renewable energy. • Natural resource requirements for renewable energy are connected to growth rates. • Arguments by recent studies ruling out physical constraints appear inadequate

European Union energy policy integration: A case of European Commission policy entrepreneurship and increasing supranationalism

International Nuclear Information System (INIS)

Maltby, Tomas

2013-01-01

Focusing on gas, this article explores the role of the European Commission in the process of European Union energy security policy development, and the extent to which the policy area is becoming increasingly supranational. Situating the article within the literature on agenda-setting and framing, it is argued that a policy window was opened as a result of: enlargement to include more energy import dependent states, a trend of increasing energy imports and prices, and gas supply disruptions. From the mid-2000s, the Commission contributed to a shift in political norms, successfully framing import dependency as a problem requiring an EU-level solution, based on the institution’s pre-existing preferences for a diversified energy supply and internal energy market. Whilst Member States retain significant sovereignty, the Commission has achieved since 2006 creeping competencies in the internal, and to a lesser extent external, dimensions of EU energy policy. - Highlights: ► We examine the development of EU energy security policy, focusing on gas. ► We examine changes in European Commission competence in energy policy. ► The European Commission has gained increased competence in the internal market. ► In the external dimension of EU energy policy Member States retain competence. ► The European Commission has had qualified success as a policy entrepreneur

Characterization of gastric adenocarcinoma cell lines established from CEA424/SV40 T antigen-transgenic mice with or without a human CEA transgene

Gastric carcinoma is one of the most frequent cancers worldwide. Patients with gastric cancer at an advanced disease stage have a poor prognosis, due to the limited efficacy of available therapies. Therefore, the development of new therapies, like immunotherapy for the treatment of gastric cancer is of utmost importance. Since the usability of existing preclinical models for the evaluation of immunotherapies for gastric adenocarcinomas is limited, the goal of the present study was to establish murine in vivo models which allow the stepwise improvement of immunotherapies for gastric cancer. Since no murine gastric adenocarcinoma cell lines are available we established four cell lines (424GC, mGC3, mGC5, mGC8) from spontaneously developing tumors of CEA424/SV40 T antigen (CEA424/Tag) mice and three cell lines derived from double-transgenic offsprings of CEA424/Tag mice mated with human carcinoembryonic antigen (CEA)-transgenic (CEA424/Tag-CEA) mice (mGC2 CEA , mGC4 CEA , mGC11 CEA ). CEA424/Tag is a transgenic C57BL/6 mouse strain harboring the Tag under the control of a -424/-8 bp CEA gene promoter which leads to the development of invasive adenocarcinoma in the glandular stomach. Tumor cell lines established from CEA424/Tag-CEA mice express the well defined tumor antigen CEA under the control of its natural regulatory elements. The epithelial origin of the tumor cells was proven by morphological criteria including the presence of mucin within the cells and the expression of the cell adhesion molecules EpCAM and CEACAM1. All cell lines consistently express the transgenes CEA and/or Tag and MHC class I molecules leading to their susceptibility to lysis by Tag-specific CTL in vitro. Despite the presentation of CTL-epitopes derived from the transgene products the tumor cell lines were tumorigenic when grafted into C57BL/6, CEA424/Tag or CEA424/Tag-CEA-transgenic hosts and no significant differences in tumor take and tumor growth were observed in the different hosts

Commissioning of energy-efficiency measures: Costs and benefits for 16 buildings

Energy Technology Data Exchange (ETDEWEB)

Piette, M.A.; Nordman, B.; Greenberg, S.

1995-04-01

Building systems and energy-efficiency measures (EEMs) often don`t perform as well in practice as expected at the design stage. This fact has become clear to many organizations concerned with ensuring building performance. What to do about these problems is less clear. Several electric utilities around the U.S. have begun to take action to address the start-up, control, and operational problems that are found in nearly every building. One of the most beneficial periods to intervene in the building life cycle is during the start-up phase of a now building. Building commissioning during start up is such an intervention. Commissioning can be defined as: a set of procedures, responsibilities, and methods to advance a system from static installation to full working order in accordance with design intent. In broad terms, commissioning can extend from design reviews through operations and maintenance planning and training. With such a broad scope aimed at the entire building life cycle, commissioning is often likened to {open_quotes}Total Quality Management{close_quotes} Yet the heart of commissioning are the procedures developed and executed to ensure that all building systems function as intended. The incorporation of energy-efficiency criteria into building commissioning is a new development.

CEA programme on gas cooled reactors

Future nuclear energy systems studies conducted by the CEA aim at investigating and developing promising technologies for future reactors, fuels and fuel cycles, for nuclear power to play a major part in sustainable energy policies. Reactors and fuel cycles are considered as integral parts of a nuclear system to be optimised as a whole. Major goals assigned to future nuclear energy systems are the following: reinforced economic competitiveness with other electricity generation means, with a special emphasis on reducing the investment cost; enhanced reliability and safety, through an improved management of reactor operation in normal and abnormal plant conditions; minimum production of long lived radioactive waste; resource saving through an effective and flexible use of the available resources of fissile and fertile materials; enhanced resistance to proliferation risks. The three latter goals are essential for the sustainability of nuclear energy in the long term. Additional considerations such as the potentialities for other applications than electricity generation (co-generation, production of hydrogen, sea water desalination) take on an increasing importance. Sustainability goals call for fast neutron spectra (to transmute nuclear waste and to breed fertile fuel) and for recycling actinides from the spent fuel (plutonium and minor actinides). New applications and economic competitiveness call for high temperature technologies (850 deg C), that afford high conversion efficiencies and hence less radioactive waste production and discharged heat. These orientations call for breakthroughs beyond light water reactors. Therefore, as a result of a screening review of candidate technologies, the CEA has selected an innovative concept of high temperature gas cooled reactor with a fast neutron spectrum, robust refractory fuel, direct conversion with a gas turbine, and integrated on-site fuel cycle as a promising system for a sustainable energy development. This objective

CEA monitoring of palliative treatment for colorectal carcinoma.

Science.gov (United States)

Herrera, M A; Chu, T M; Holyoke, E D; Mittelman, A

1977-01-01

Palliative treatment was applied to 131 cases of unresectable or palliatively resected colorectal carcinoma being monitored with serial CEA determinations. There were 84 instances of disease progression with 67 (80%) of them showing an increase in CEA above pretreatment levels or maintaining high levels, and 17 (20%) showing a fall when compared to pretreatment values or maintaining low initial values. There was a clear-cut regression of the disease in only 9 instances. In all 9, the CEA clearly dropped or maintained low valles throughout the period of regression. No patient in regression had a rise or maintained an elevated CEA level. These changes in CEA followed closely the clinical response of our patient to the use of a particular agent, although for the Nitrosourea compounds there may be a tendency to lower the CEA regardless of the patient's tumor response to the drug. This could be due to the fact that the Nitrosoureas produce a diffuse block of cellular activity, both at the nucleous and cytoplasm; while other compounds act as alkylating agents or by inhibition of enzymes involved in the metabolism of nucleic acids (i.e., 5-FU inhibiting thymidylate synthetase). In general, longer survival was found in those patients who had initially lower levels of CEA as compared to those with high initial levels. The patients with a favorable CEA response to the treatment (falling CEA or maintained low value), even in many who did not show a clinical response had a longer survival than the group with rising or stable high levels. The main value in CEA monitoring of patients resides in its correlation with the amount of disease present and then its ability to detect progression of tumor mass which is not clinically measurable.

An important program is currently in progress at several laboratories over the world for the development of sensitive, practical non-destructive assay techniques for the quantification of low level transuranics (TRU) in solid wastes. The wide variety of materials and contaminants, the low concentrations and large volumes involve, all make this kind of assay a complicated affair. Over the last few years, considerable progress has been made in the field of assay techniques for low level contaminated wastes. This report describes the methods being developed at French Atomic Energy Commission (C.E.A.) in Cadarache to assay high density TRU waste packages by using photon, neutron or both photon and neutron as interrogating particles. All of these particles are produced by using a pulsed electron linear accelerator from which the photons are produced following Bremsstrahlung phenomena on a heavy metallic converter and the neutrons are generated in appropriate low level photoneutron threshold target (e.g. Beryllium). The dynamic of photonuclear interactions and photoneutron production, use of an electron linear accelerator as a particle source, experimental and electronics details, experimental results, simulation to experiment performances and future experimental and theoretical studies are discussed.

Building Commissioning: A Golden Opportunity for Reducing Energy Costs and Greenhouse-gas Emissions

Energy Technology Data Exchange (ETDEWEB)

Mills, Evan

2009-07-16

The aim of commissioning new buildings is to ensure that they deliver, if not exceed, the performance and energy savings promised by their design. When applied to existing buildings, commissioning identifies the almost inevitable 'drift' from where things should be and puts the building back on course. In both contexts, commissioning is a systematic, forensic approach to quality assurance, rather than a technology per se. Although commissioning has earned increased recognition in recent years - even a toehold in Wikipedia - it remains an enigmatic practice whose visibility severely lags its potential. Over the past decade, Lawrence Berkeley National Laboratory has built the world's largest compilation and meta-analysis of commissioning experience in commercial buildings. Since our last report (Mills et al. 2004) the database has grown from 224 to 643 buildings (all located in the United States, and spanning 26 states), from 30 to 100 million square feet of floorspace, and from $17 million to $43 million in commissioning expenditures. The recorded cases of new-construction commissioning took place in buildings representing $2.2 billion in total construction costs (up from 1.5 billion). The work of many more commissioning providers (18 versus 37) is represented in this study, as is more evidence of energy and peak-power savings as well as cost-effectiveness. We now translate these impacts into avoided greenhouse gases and provide new indicators of cost-effectiveness. We also draw attention to the specific challenges and opportunities for high-tech facilities such as labs, cleanrooms, data centers, and healthcare facilities. The results are compelling. We developed an array of benchmarks for characterizing project performance and cost-effectiveness. The median normalized cost to deliver commissioning was $0.30/ft2 for existing buildings and $1.16/ft2 for new construction (or 0.4% of the overall construction cost). The commissioning projects for which

Environmental monitoring and independent analysis: the experience of the local information commission in Cadarache

International Nuclear Information System (INIS)

Foucher, M.

2010-01-01

The 2006 Act on 'Open Access to Information and Nuclear Safety' provides free access to nuclear installations data and submits nuclear facilities to an independent administrative authority, the ASN (French Nuclear Safety Authority). A local information committee (CLI - Commission locale d'informations) has been set up for each nuclear facility. It includes all the parties involved and may commission expert studies and environmental measurement tests from independent laboratories. Prompted by environmental organizations, the Cadarache CLI commissioned a CRIIRAD (Commission de Recherche et d'Informations Independantes sur la Radioactivite) fact-finding survey in 2008-2009 to evaluate the environmental impact of the CEA/Cadarache installations since they were created. This study points to a moderate present impact, though a lack of data makes it impossible to reconstruct environmental impact prior to 1979. A set of guidelines are put forward to assess the past impact in greater detail and to lessen the current impact even further. Following this study, additional steps to minimize this impact will be taken by CEA/Cadarache inside the facilities, and by the relevant LCI outside the installations. Developing independent expert skills is a major challenge for CLIs to gain better knowledge of nuclear activities and improve their local management. (author)

A look at new key performance criteria that could most affect the safety of long term storage of nuclear waste. A case study commissioned by CEA

Marvy, A.; Lioure, A.; Heriard-Dubreuil, G.; Gadbois, S.; Schneider, T.; Schieber, C

2002-01-01

As part of the work scope set in the French law on high level long lived waste R and D passed in 1991, CEA is conducting research work to establish the scientific basis and assess the feasibility of long term storage as an option for the safe management of nuclear waste for periods as long as a few centuries. This goal is a significant departure from current industrial practice where storage facilities are usually built to last only a few decades. From a technical viewpoint such an extension in time seems feasible provided care and maintenance is exercised. Considering such long periods of time risk for Society of loosing oversight and control of such a facility is real which triggers the question of whether and how long term storage safety can be actually achieved. Therefore CEA commissioned a study in which MUTADIS Consultants and CEPN were both involved. The case study looks into several past and actual human enterprises conducted over significant periods of time - one dating back to the end of the 18th century - and identified off the nuclear field. Then-prevailing societal behaviour and organizational structures are screened out to show how they were and are still able to cope with similar oversight and control goals. As a result the study group obtained a set of performance criteria relating to issues like responsibility, securing funds, legal and legislative implications, economic sustainable development, all being areas which are not traditionally considered when technical studies are conducted. These criteria can be most useful from the design stage onward, first in an attempt to define the facility construction and operating guiding principles, and thereafter to substantiate the safety case for long term storage and get geared to the public dialogue on that undertaking should it become a reality.

In the nineties, CEA has undertaken to develop the production of high intensity light ion beams from plasma generated by electron cyclotron resonance (ECR). Important results were obtained with the SILHI source in pulsed or continuous mode. Presently, CEA/Saclay is now involved in the construction of different injectors dedicated to large infrastructures like IFMIF or SPIRAL2. Other installations are also interested by high intensity ion sources like ESS or FAIR. To improve and test new sources, a new test bench named BETSI (Banc d'Etudes et de Tests des Sources d'Ions) has been operating for several years. Low energy beam line diagnostics consist of a Faraday cup, cameras and a species analyzer. The SILHI emittance scanner can also be installed on the beam line. On this test bench, different permanent magnet source configurations are tested. The paper is followed by the associated poster. (authors)

Within the overall federal geothermal program, the Atomic Energy Commission has chosen to concentrate on development of resource utilization and advanced research and technology as the areas most suitable to the expertise of its staff and that of the National Laboratories. The Commission's work in geothermal energy is coordinated with that of other agencies by the National Science Foundation, which has been assigned lead agency by the Office of Management and Budget. The objective of the Commission's program, consistent with the goals of the total federal program is to facilitate, through technological advancement and pilot plant operations, achievement of substantial commercial production of electrical power and utilization of geothermal heat by the year 1985. This will hopefully be accomplished by providing, in conjunction with industry, credible information on the economic operation and technological reliability of geothermal power and use of geothermal heat.

2000-01-01

Following several years of laboratory research initiated in 1983 on a nonradioactive prototype unit at the CEA's (Atomic Energy Commission) Valrho/Marcoule Research Center, an innovative process, IRIS, has been developed to meet the need for processing nuclear glove box waste. It is to our knowledge the only high-capacity process in the world capable of dealing with highly chlorinated (25 wt% chlorine) alpha-contaminated waste. IRIS is based on a two-step incineration process combining pyrolysis and calcination with a specific off-gas treatment. The nonradioactive prototype at Marcoule has operated for over 5000 hours, demonstrating the following advantages: - Highly effective process control through regular, continuous feed of the rotating tubular kiln. - Very effective control of corrosion by pyrolytic decomposition of organo-chlorine compounds at 550 deg. C under inert atmosphere. - High ash quality (< 1% carbon, < 1% chlorine) compatible with online radionuclide recovery or vitrification processes. - High waste/ash weight and volume reduction factors (30 in both cases). - Very low gas flow rates limiting waste entrainment compared with direct incineration. - Very high efficiency off-gas treatment complying with gaseous emission standards. - Protection of system piping by substitution of stable phosphates for metal chlorides generated in the off-gas lines. - Flexible process capacity from a few kg/h for nuclear waste to 500 kg/h for conventional waste. In December 1991, the CEA's Valduc Center decided to build the first industrial facility based on the IRIS process. Construction work, equipment design and assembly, nonradioactive testing and preparation of the safety report lasted six years. The facility successfully began operating with radioactive waste on March 10, 1999, substantiating the R and D effort. Three other nuclear industrial operators around the world have adopted the IRIS process for future implementation. (authors)

The Energy Commission's notice to the Minister of Natural Resources regarding the place of wind energy in Quebec's energy portfolio

International Nuclear Information System (INIS)

Dumais, A.; Frayne, A.; Tanguay, F.

1998-01-01

In December 1997 Quebec's Minister of Natural Resources requested that the Energy Commission advise him on the quota given to wind energy in the future energy development plans of Hydro-Quebec. The Commission's report to the Minister includes 18 recommendations. Among these is a recommendation that an assessment of wind resources be conducted as soon as possible to identify suitable sites for the installation of wind turbines. A provincial program for the development of wind energy is also recommended, to be initiated by the year 2002, and that it should proceed over the next nine years to reach a target production capacity of 450 MW by the year 2011. This production would come from the yearly installation of 60 to 70 wind turbines of 750 kV. The Commission also recommended that in the initial years costs for this wind energy not exceed that of the Le Nordais project, i.e. 5.8 cents per kWh. Any additional costs incurred in the generation of wind electricity over conventional hydro power should be assumed by the Quebec Government. Conversely, in instances where the wind power is sold to consumers outside of the province, Hydro-Quebec should pay for the full cost of this power. 8 tabs., 1 appendix

1984-01-01

For its 'Framework Programme 1984-1987' the Commission has defined the major goals for a European Scientific and Technical Strategy. One of the means to reduce the energy dependence of the Community, which is an important objective, is to favour the development of nuclear fission energy. As electricity production by nuclear reactors has reached industrial maturity, the Community activities are directed mainly to safety aspects, in order to ensure the protection of workers and the general public, against hazards linked to operations in the nuclear fuel cycle. A description of the main features of the five sub-programmes on nuclear fission energy is given below; these programmes are: reactor safety; nuclear fuels and actinides research; management of radioactive waste; safeguarding and management of fissile materials; decommissioning of nuclear installations. The research and development work is carried out either by the Commission's Joint Research Center or by organizations and companies of the Member Countries, with the Commission's financial support.

This document describes the content of a CEA policy relating to very low level waste management elaborated in application of the waste management principles defined in France. The policy deals with very low level waste, subject to recycling, incineration or landfill disposal. It does not deal with reuse. The following principles are applicable to waste streams produced by CEA nuclear installations either during operating or dismantling activities. The policy deals only with very low level wastes (VLLW) (order of magnitude: <100 Bq/g for high energy emitters). It does not deal with low, intermediate or high level waste, which are either recycled or incinerated in nuclear industry or disposed of in the Aube surface disposal (CSA) or kept in intermediate storage, before geological disposal or any alternative final solution

Energy modelling with SOPKA-E for the energy paths of the Commission of Inquiry on ''Future nuclear energy policy''

International Nuclear Information System (INIS)

Faude, D.

1983-03-01

The Commission of Inquiry on ''Future nuclear energy policy'' of the 8th Deutscher Bundestag has examined the question of the longterm exploitation of nuclear energy in the Federal Republic of Germany within a more general framework of energy policy and, for this purpose, created the concept of energy paths. To calculate these energy paths, the SOPKA-E simulation model has been developed and applied at the Karlsruhe Nuclear Research Center. In Chapter 2, the central part of this report, the form and contents of path modeling are described in detail. To help readers understand the energy paths concept, the general background of energy policy in the seventies, which gave rise to the contents of the energy paths, is outlined in a survey article in Chapter 1. Chapter 3 is a description of the energy projections contained in the joint expert opinion on the third updated version of the Energy Program in the light of the energy paths. In Chapter 4 some approaches - albeit fragmentary - are outlined which have been adopted by the Commission of Inquiry of the 9th Deutscher Bundestag in adapting energy paths to the present situation. The presentation in this report of the model computations with SOPKA-E is meant to be a documentation. (orig./UA) [de

Hydrogen role in a carbon-free energy mix

International Nuclear Information System (INIS)

2014-02-01

Among the energy storage technologies under development today, there is today an increasing interest towards the hydrogen-based ones. Hydrogen generation allows to store electricity, while its combustion can supply electrical, mechanical or heat energy. The French Atomic Energy Commission (CEA) started to work on hydrogen technologies at the end of the 1990's in order to reinforce its economical interest. The development of these technologies is one of the 34 French industrial programs presented in September 2013 by the French Minister of productive recovery. This paper aims at identifying the hydrogen stakes in a carbon-free energy mix and at highlighting the remaining technological challenges to be met before reaching an industrial development level

The use of CEA as a prognostic and predictive marker in patients with lung cancer is widely debated. The aim of this review was to evaluate the results from studies made on this subject. Using the search words "CEA", "tumor markers in lung cancer", "prognostic significance", "diagnostic significance" and "predictive significance", a search was carried out on PubMed. Exclusion criteria was articles never published in English, articles before 1981 and articles evaluating tumor markers in lung cancer not involving CEA. Initially 217 articles were found, and 34 were left after selecting those relevant for the present study. Four of these included both Non-Small Cell Lung Cancer (NSCLC) and Small Cell Lung Cancer (SCLC) patients, and 31 dealt solely with NSCLC patients. Regarding SCLC no studies showed that serum level of CEA was a prognostic marker for overall survival (OS). The use of CEA serum level as a prognostic marker in NSCLC was investigated in 23 studies and the use of CEA plasma level in two. In 18 (17 serum, 1 plasma) of these studies CEA was found to be a useful prognostic marker for either OS, recurrence after surgery or/and progression free survival (PFS) in NSCLC patients. Interestingly, an overweight of low stage (stage I-II) disease and adenocarcinoma (AC) patients were observed in this group. The remaining 7 studies (6 serum, 1 plasma) contained an overweight of patients with squamous carcinoma (SQ). One study found evidence for that a tumor marker index (TMI), based on preoperative CEA and CYFRA21-1 serum levels, is useful as a prognostic marker for OS in NSCLC. Six studies evaluated the use of CEA as a predictive marker for risk of recurrence and risk of death in NSCLC patients. Four of these studies found, that CEA was useful as a predictive marker for risk of recurrence and risk of death measured over time. No studies found CEA levels useful as a diagnostic marker for lung cancer. With regard to NSCLC the level of CEA measured in tumor tissue in

Ratemaking treatment of decommissioning costs by the Federal Energy Regulatory Commission

International Nuclear Information System (INIS)

Lenart, R.J.

1985-01-01

The Nuclear Regulatory Commission (NRC) has the responsibility for the assurance of funds at the time of decommissioning. The Federal Energy Regulatory Commission (FERC), in conjunction with the State Public Utility Commissions, have the responsibilty to ensure that utilities have just and reasonable rates and an opportunity to collect an appropriate amount of dollars to decommission a nuclear reactor at the conclusion of its service life. Therefore, the Federal Energy Regulatory Commission allows utilities to include nuclear power plant decommissioning costs in rates based on the following ratemaking concepts: (1) that the methodology used by a utility equitably allocates costs between present and future ratepayers who receive service from a nuclear unit; (2) that, given the uncertainty and imprecision that are included in cost estimates for events that will transpire 20-40 years in the future, the FERC chose to err on the low side rather than run the risk of overcharging current customers for future decommissioning expense; and (3) that, as decommissioning experience accumulates, as decommissioning technology improves, and as decommissioning estimates become more refined, utilities would continue to seek revised decommissioning expense allowances from FERC in order to ensure that actual decommissioning costs are recovered over the useful life in which the plant provides service

Full text: CEA (Commissariat a l'Energie Atomique), as nuclear operator, is responsible for the control and protection of their nuclear materials. Inside CEA, DCS (Central Security Division) is in charge of the security matters, DCS defines the CEA strategy in this field, especially in physical protection. The paper will present the physical protection strategy of CEA. DCS defines the rules and methods; the operators have to apply in order to fulfill the security objectives of CEA. CEA has to provide the regulatory authority with documents proving that it is in accordance with the requirements of the 25th July 1980 law and 12th May 1981 decree. It has to implement all the necessary means in order to achieve the results requested by the regulatory authority. All these arrangements are described in the 'license and control file'. This file should specify the facility safeguards and physical protection system. Accounting measures are also described. In this file, the petitioner has to justify its capacity for holding nuclear materials and for exercising authorized activities on them. So the organization and the installed means have to be described in this authorization file. For physical protection, containment, surveillance and physical protection measures are presented: Containment measures must prevent the unauthorized or unjustified movements of nuclear material in the framework of the authorized activities; Surveillance measures must guarantee the integrity of the containment, check that no material is exiting by an abnormal channel; Physical protection measures for the materials, the premises and the facilities are intended to protect them against malevolent actions by means of security systems. The Central Security Division has established guidelines to provide guidance to the nuclear materials holders in writing such files. Each holding unit has to establish a 'license and control file' and each CEA site establishes a 'site license and control file

Selecting the research efforts to be highlighted in the Israel Atomic Energy Commission`s Annual Report from the large body and broad spectrum of ongoing work is not an easy task. The extensive bibliography of published results attached to the report attests to the scope of this difficulty. Of the many worthwhile projects, four were chosen to represent best the current trends in the continuing R and D program at the research centers of the Israel Atomic Energy Commission. One of these trends is the growing cooperation with private industry, in an attempt to gear our R and D programs to respond to market demands. Another feature, noted already several years ago, is the extensive collaboration of our scientists and engineers with colleagues at other institutions, in Israel and abroad. some of the work reported is part of evolving international industrial cooperation projects, illustrating both these trends. Following a trend common to many nuclear research centers around the world, a substantial part of our research effort is non-nuclear in nature. This is illustrated in the first article, which deals with advances in the application of non-linear optics in diverse fields of science and technology. These include state-of-the-art solid-state lasers, rapid modulation of light signals, development and generation of tunable sources of coherent light, optical data storage and the microscopic probing of biological and inorganic samples. The present work reports on a range of R and D, from the fundamentals of non-linear optical materials to proof-of-principle demonstrations of non-linear subwavelength resolution microscopy, to fabrication of prototype commercial tunable laser systems The second report considers the microstrain characteristics in some alloys using X-ray diffraction (XRD). The research utilizes XRD line broadening effects to study the characteristics of alloys from especially prepared surfaces. These characteristics include the homogeneity of alloying

In the beginning of the 90s,T.Taylor and his collaborators demonstrated ECR sources operating at low frequency (I.e.2.45GHz) are able to produce very intense single charge light ion beams.At CEA/Saclay,the SILHI source developments started in 1995.Since 1997 more than 100mA proton or deuteron beams are routinely produced in pulsed or continuous mode.To comply with ADS reliability constraint,important improvements have been performed to increase the installation reliability.Moreover,to optimize the beam transport in the low energy beam line,the extraction system was carefully designed and space charge compensation studies were undertaken.An important step has been reached in 2005 with the development of a permanent magnet source able to produce a total beam of 109mA at 85kV.A new test bench named BETSI,especially dedicated to permanent magnet source developments,is presently under construction.It will allow analysing positive or negative extracted beams up to 50keV and 100mA.In addition,for several years work has been done to optimize the production of negative hydrogen ion beam with such an ECR source.Recent analysis pushed towards the construction of a new set up based on a multicusp magnetic configuration.After a brief overview of the CEA/Saclay source developments,this article will point out on the recent results and present status.

Challenges Ahead for Nuclear Facility Site-Specific Seismic Hazard Assessment in France: The Alternative Energies and the Atomic Energy Commission (CEA) Vision

Berge-Thierry, C.; Hollender, F.; Guyonnet-Benaize, C.; Baumont, D.; Ameri, G.; Bollinger, L.

2017-09-01

Seismic analysis in the context of nuclear safety in France is currently guided by a pure deterministic approach based on Basic Safety Rule ( Règle Fondamentale de Sûreté) RFS 2001-01 for seismic hazard assessment, and on the ASN/2/01 Guide that provides design rules for nuclear civil engineering structures. After the 2011 Tohohu earthquake, nuclear operators worldwide were asked to estimate the ability of their facilities to sustain extreme seismic loads. The French licensees then defined the `hard core seismic levels', which are higher than those considered for design or re-assessment of the safety of a facility. These were initially established on a deterministic basis, and they have been finally justified through state-of-the-art probabilistic seismic hazard assessments. The appreciation and propagation of uncertainties when assessing seismic hazard in France have changed considerably over the past 15 years. This evolution provided the motivation for the present article, the objectives of which are threefold: (1) to provide a description of the current practices in France to assess seismic hazard in terms of nuclear safety; (2) to discuss and highlight the sources of uncertainties and their treatment; and (3) to use a specific case study to illustrate how extended source modeling can help to constrain the key assumptions or parameters that impact upon seismic hazard assessment. This article discusses in particular seismic source characterization, strong ground motion prediction, and maximal magnitude constraints, according to the practice of the French Atomic Energy Commission. Due to increases in strong motion databases in terms of the number and quality of the records in their metadata and the uncertainty characterization, several recently published empirical ground motion prediction models are eligible for seismic hazard assessment in France. We show that propagation of epistemic and aleatory uncertainties is feasible in a deterministic approach, as in a

Full Text Available Serum tumor markers (TM are widely used for diagnosis and monitoring of treatment of cancer. Carcinoembryonic Antigen (CEA is one of the most widely investigated tumor markers in gastrointestinal (GI cancers. Estimation of circulating tumor markers is a non- invasive quantitative method. Serum levels of CEA were studied for diagnosis and prognosis of gastrointestinal malignancies. 140 subjects were undertaken out of which 35 normal and remaining 105 were GI cancer patients. Serum levels of CEA were analyzed by Enzyme Linked Immunosorbent Assay (ELISA. Result of serum CEA levels of the GI cancer patients and normal subjects were analyzed statistically. It was observed that there was significant increase in (P <0.01 in CEA levels of oesophagus, stomach and colon cancer patients as compared to normal subjects. The levels of CEA decreased significantly after the surgery but the decrease in levels of CEA was not up to the levels as normal control subjects.

Coelingh, G J; Mess, K H

2008-01-01

The risk of damage to the superconducting magnets, bus bars and current leads of the LHC machine in case of a resistive transition (quench) is being minimized by adequate protection. The protection is based on early quench detection, bypassing the quenching magnets by cold diodes, energy density dilution in the quenching magnets using heaters and, eventually, energy extraction. For two hundred and twenty-six LHC circuits (600 A and 13 kA) extraction of the stored magnetic energy to external dump resistors was required. All these systems are now installed in the machine and the final hardware commissioning has been undertaken. After a short description of the topology and definitive features, layouts and parameters of these systems the paper will focus on the results from their successful commissioning and an analysis of the system performance.

Influencing factors on the serum carcinoembryonic antigen (CEA) in benign liver diseases

International Nuclear Information System (INIS)

Pompecki, R.; Mehl, H.; Fehr, R.; Braun, H. von

1982-01-01

Carcinoembryonic antigen (CEA) was determined in the sera of 452 patients with benign liver diseases by radioimmunoassay (CEA-RIA Kit, Abbott). The CEA-level exceeded 2.5 ng/ml in 39 percent and 5.0 ng/ml in 9 percent of the cases. Independent influences of age, nicotin, and alcohol consumption and connective tissue proliferation of the liver on the CEA level were demonstrated and quantified by two- and higher-dimensional contingency table analysis. Toxic liver diseases were combined with elevated serum CEA values more often than inflammatory diseases. This aspect could not be investigated independently since there were only a few cases of toxic liver diseases without alcohol consumption. Sex and relative body weight do not seem to affect the CEA level. Additional diseases of the gastrointestinal tract or the cardiovascular system did not influence the serum CEA level in liver diseases. Therefore, in patients with benign liver diseases, an elevated serum CEA level indicates increased proliferation of the connective tissue. Age, nicotin, and alcohol consumption have to be considered independently in the clinical judgement of elevated serum CEA levels, irrespective of the underlying disease. (orig.) [de

Currently, houses do not perform optimally or even as many codes and forecasts predict, largely because they are field assembled and there is no consistent process to identify deficiencies or to correct them. Solving this problem requires field performance evaluations using appropriate and agreed upon procedures in the form of a new process called residential commissioning. The purpose of this project is to develop and document these procedures and to demonstrate the value that applying them could provide in both new and existing California houses. This project has four specific objectives: to develop metrics and diagnostics for assessing house performance, to provide information on the potential benefits of commissioning using a whole-house approach, to develop programmatic guidelines for commissioning, and to conduct outreach efforts to transfer project results to industry stakeholders. The primary outcomes from this project are the development of residential commissioning guidelines and the analytical confirmation that there are significant potential benefits associated with commissioning California houses, particularly existing ones. In addition, we have made substantial advances in understanding the accuracy and usability of diagnostics for commissioning houses. In some cases, we have been able to work with equipment manufacturers to improve these aspects of their diagnostic tools. These outcomes provide a solid foundation on which to build a residential commissioning program in California. We expect that a concerted effort will be necessary to integrate such a program with existing building industry efforts and to demonstrate its use in the field.

The as-developed nanosized material device, consisting of surface decorated maghemite nanoparticles suspended as a biocompatible magnetic fluid (MF sample, labeled MF-anti-CEA, was characterized and tested against two cell lines: a high-CEA expressing cell line (LS174T and a low-CEA expressing cell line (HCT116. Whereas X-ray diffraction was used to assess the average core size of the as-synthesized maghemite particles (average 8.3 nm in diameter, dynamic light scattering and electrophoretic mobility measurements were used to obtain the average hydrodynamic diameter (550 nm and the zeta-potential (−38 mV of the as-prepared and maghemite-based nanosized device, respectively. Additionally, surface-enhanced Raman spectroscopy (SERS was used to track the surface decoration of the nanosized maghemite particles from the very first precoating up to the attachment of the anti-CEA moiety. The Raman peak at 1655 cm−1, absent in the free anti-CEA spectrum, is the signature of the anti-CEA binding onto the precoated magnetic nanoparticles. Whereas MTT assay was used to confirm the low cell toxicity of the MF-anti-CEA device, ELISA and Prussian blue iron staining tests performed with both cell lines (LS174T and HCT116 confirm that the as-prepared MF-anti-CEA

The aim of this study was to evaluate which of these two markers are in better correlate with the disease in patients surgically treated for breast cancer. Material and Methods: We retrospectively reviewed values of CA15-3 and CEA in 342 patients (median age 52.18 years, range 27-78 years) with surgically treated and pathologically proven breast cancer. CA15-3 and CEA was measured by radioimmunoassay. CA15-3 levels above 30 U/ml and CEA levels above 5 ng/ml were considered as positive values. Results: Out of 342 patients, 86 had elevated CA15-3 levels (sensitivity: 25.1%) and 68 of 342 patients had positive CEA levels (sensitivity 19.9%). Two hundred thirty seven (237) of the patients suffering from breast cancer (69.3%) did not have metastatic disease. In this group CA15-3 sensitivity was 94.5%, while CEA sensitivity was 87.3%. One hundred and five (105) patients (30.7%) had metastatic disease. In this group, CA15-3 sensitivity was 69.5% and CEA sensitivity was 36.2% (P < 0.05). With regard to the correlation of the two tumor markers with clinical course patients had significantly higher levels of CA15-3 than of CEA in metastatic breast cancer. Conclusion: This result suggests CA15-3 to be the more sensitive and more specific of the two tumor markers for metastatic breast cancer detection and monitoring

Aim: The purpose of this study was to assess the potential for radioimmunodetection (RAID) of murine anti-carcinoembryonic antigen (CEA) monoclonal antibody (MAb) F33-104 labeled with technetium-99m (99m-Tc) by a reduction-mediated labeling method. Methods: The binding capacity of 99m-Tc-labeled anti-CEA MAb F33-104 with CEA by means of in vitro procedures such as immunoradiometric assay and cell binding assay and the biodistribution of 99m-Tc-labeled anti-CEA MAb F33-104 in normal nude mice and nude mice bearing human colon adenocarcinoma LS180 tumor were investigated and compared with 99m-Tc-labeled anti-CEA MAb BW431/26. Results: The in vitro binding rate of 99m-Tc-labeled anti-CEA MAb F33-104 with CEA in solution and attached to the cell membrane was significantly higher than 99m-Tc-labeled anti-CEA MAb BW431/261 (31.4 ± 0.95% vs. 11.9 ± 0.55% at 100 ng/mL of soluble CEA, 83.5 ± 2.84% vs. 54.0 ± 2.54% at 10 7 of LS 180 cells). In vivo, accumulation of 99m-Tc-labeled anti-CEA MAb F33-104 was higher at 18 h postinjection than 99m-Tc-labeled anti-CEA MAb BW431/26 (20.1 ± 3.50% ID/g vs. 14.4 ± 3.30% ID/g). 99m-Tc-activity in the kidneys of nude mice bearing tumor was higher at 18 h postinjection than at 3 h (12.8 ± 2.10% ID/g vs. 8.01 ± 2.40% ID/g of 99m-Tc-labeled anti-CEA MAb F33-104, 10.7 ± 1.70% ID/g vs. 8.10 ± 1.75% ID/g of 99m-Tc-labeled anti-CEA MAb BW431/26). Conclusion: 99m-Tc-labeled anti-CEA MAb F33-104 is a potential novel agent for RAID of recurrent colorectal cancer. (orig.) [de

Radioimmunologic assays of blood serum carcinoembryonic antigen (CEA) level were conducted at major stages of treatment of gastric cancer by subtotal stomach resection and gastrectomy with preliminary cryotreatment and thawing of tumor. A short-term rise in CEA level occurred in 53.9 % of cases 3-4 days after combined therapy. A decrease in CEA concentration at discharge from hospital as compared with preoperative level and that registered 3-4 days after operation was observed in 50 and 75 % of cases of combined therapy, respectively, and 47.5 and 37.5 % of controls (surgery without cryotreatment). There was nocorrelation between cryotreatment and changes in CEA level in gastric ulcer patients

Plasma carcinoembryonic antigen (CEA) levels were measured by an immunoenzymic method (Abbott) in 1020 subjects attending the Preventive Medicine Centre (Vandoeuvre-les-Nancy). The results are assessed in relation to: sex, age, body build, fasting/normal food intake, smoking, alcohol intake, drug medication, and working environment. The mean plasma CEA level is 1.53 ng/ml. 87% of the total group has levels less than 2.5 ng/ml, 11.2% levels between 2.5 ng/ml and 5 ng/ml and 1.8% levels above 5 ng/ml. One person had a level above 10 ng/ml. Men had significantly higher CEA levels than women. Smoking was more frequent in both men and women with CEA levels above 2.5 ng/ml. Only in men were age, alcohol consumption and a poor work environment significantly associated with CEA levels higher than 2.5 ng/ml. Obesity in women was related to higher CEA levels. Food intake and drug medication were without influence on the CEA level.

Full Text Available The Working Party on International Nuclear Data Evaluation Co-operation (WPEC subgroup 29 (SG 29 was established to investigate an issue with the 235U capture cross-section in the energy range from 0.1 to 2.25 keV, due to a possible overestimation of 10% or more. To improve the 235U capture crosssection, a new 235U evaluation has been proposed by the Institut de Radioprotection et de Sûreté Nucléaire (IRSN and the CEA, mainly based on new time-of-flight 235U capture cross-section measurements and recent fission cross-section measurements performed at the n_TOF facility from CERN. IRSN and CEA Cadarache were in charge of the thermal to 2.25 keV energy range, whereas the CEA DIF was responsible of the high energy region. Integral experiments showing a strong 235U sensitivity are used to assess the new evaluation, using Monte-Carlo methods. The keff calculations were performed with the 5.D.1 beta version of the MORET 5 code, using the JEFF-3.2 library and the new 235U evaluation, as well as the JEFF-3.3T1 library in which the new 235U has been included. The benchmark selection allowed highlighting a significant improvement on keff due to the new 235U evaluation. The results of this data testing are presented here.

The Commission to Review the Effectiveness of the National Energy Laboratories was charged by Congress in January 2014 to evaluate the mission, capabilities, size, performance, governance, and agency oversight of the 17 Department of Energy (DOE) laboratories. Given the incredibly broad scope and aggressive timeline (the original deadline was February 2015), the Secretary of Energy and Congress agreed to split the task into two phases. This interim report contains the preliminary observations and recommendations gleaned from Phase 1 of the study, which consisted of a literature review; visits to five of the National Laboratories; semi-structured interviews with staff from across the National Laboratories, DOE, other Federal agencies, companies, other non-governmental organizations, and additional interested parties; and presentations at monthly public Commission meetings. The Commission notes that the purpose of the National Laboratories is to provide critical capabilities and facilities in service of DOE’s mission and the needs of the broader national and international science and technology (S&T) community, including other Federal agencies, academia, and private industry. The National Laboratories are successfully fulfilling that mission today. While the Commission believes significant improvements can be made to many aspects of DOE management and governance of the laboratories, those issues do not detract from the National Laboratories’ remarkable contributions to the American public. In Phase 2 the Commission will focus on ways to make the process of carrying out their missions more efficient and effective.

Introduction to the CEA family: structure, function and secretion.

Von Kleist, S

1992-01-01

Due to the phenomenal progress in the field of tumor immunology that took place during the last twenty years, we dispose today of highly specific and sensitive techniques and reagents like monoclonal antibodies (MAbs). In this context the discovery in human carcinomas of tumor-associated antigens, such as CEA, was of primary importance, especially since the latter was found to have clinical relevance as a tumor marker. Based on animal models, a new in vivo technology for the detection of tumors and metastases was developed in recent years, that uses anti-CEA MAbs, or fragments of them, coupled to radio-isotopes. This technique, called radio-immunodetection (RAID), also paved the way for immunotherapeutic procedures, where again CEA served as the target-antigen. This new technique holds great promise, provided the epitope-specificity of the MAbs is well-controlled: it has been shown that CEA belongs to a large gene-family of at least 22 members, which can be subdivided into two subgroups (i.e., the CEA- and the PSG-subgroup) and which in turn belongs to the immunoglobulin-supergene family. Great structural similarities render the distinction of the various cross-reactive molecules by immunological means rather difficult.

After a presentation of the organisation, role and missions of the French Commission for Energy Regulation (CRE), and of its relationship with other institutional actors, this report describes and comments the action of the CRE in the fields of dialogue and transparency. It presents and comments key figures regarding the electricity and gas retail markets. It reports and comments the European reaction to the cold peak of February 2012 (historical peak for consumption and prices, inquiry on the causes of these price peaks, need of a European market). The next part addresses the relationship between electricity grids and territories (solidarity between electricity grids as the basis of the Europe of energy, evolution of French grids to face new needs and to take regional and local dimensions into account). Another part addresses gas infrastructures which are considered as the cornerstone of a good operation for the French market and for the integration of the European energy market (gas world market in 2012, definition of a target model for the gas market by European regulators, evolution of the French market in compliance with the European target model, new tariffs for the use of natural gas transport networks). The report then addresses the development of renewable energies: actions of CRE (bidding, opinion of tariffs), influence of renewable energy development on electricity prices on gross markets, needed evolution of electricity grids. A last part addresses the issues of energy cost, demand management, and struggle against energy poverty

The aim of this investigation was to study the possible diagnostic value of a CEA test in cancer of the renal pelvis and ureter. Thirty-eight patients with upper urinary tract cancer, 15 patients with transitional cell carcinoma of the bladder, 6 kidney carcinoma patients and 25 healthy adults were studied. CEA was determined in tumor tissue, serum and urine, by using a monoclonal radioimmunoassay. Increased serum CEA level was found in 7 out of 27 patients (26%) with active cancer of the renal pelvis and ureter. None of 11 patients with inactive cancer had an increased serum CEA level. No significant correlation was found between the serum CEA level and the histological grading. The tumor CEA content varied markedly, from values obtainted in normal urothelium up to 840 ng/g wet weight. CEA content of tumor tissue did not correlate with the serum level. Our data suggest that serum and urine CEA have not diagnostic accuracy for clinical diagnosis of upper tract urothelial cancer. (orig.) [de

To investigate the correlation between serum CEA and colorectal cancer, the pre-and postoperative serum CEA in 120 patients with colorectal cancer was measured by RIA, with other 24 cases of healthy donors as control. The results showed that serum CEA in control group and patient group were 9.84±2.44 ng/mL, 38, 85±19.21 ng/mL respectively, while colonic cancer group 37.43±18.58 ng/mL, rectal cancer group 39.72±20.67 ng/mL. There was significant difference between patient group and control group (P 0.05). Serum CEA of 37 among 44 cases with positive CEA findings decreased to 11.21±3.65 ng/mL during two months follow-up post-operation, whereas 50.63±24.38 ng/mL in 7/44 cases undergoing non-radical operation. The serum CEA of 41 recurrence cases was 43.12±17.15 ng/mL at six-year post-operation, with 87.80% of three-year recurrence rate. It suggested that the serum CEA test is a convenient method for colorectal cancer to preoperatively diagnose it, evaluate postoperative curative effect and detect tumor recurrence and metastasis

To compare accumulation of the 125 I-labeled antibodies(anti-carcinoembryonic antigen(CEA) monoclonal antibody and polyclonal antibody) to a CEA-producing tumor (SC-2-JCK), an in vivo localization study was performed in nude mice. The tumor-to-blood ratio at 120 hours after injection rose to 4.6 for the monoclonal antibody, but remained at 1.3 for the polyclonal antibody. However, no differences were noted between the antibodies up to 72 hours after injection. In autoradiograms, selective accumulation of the tracer was noted in the tumor for both antibodies. However, no superiority or inferiority of imaging for either of the antibodies could be definitely determined. (author)

Building thermography as a tool in energy audits and building commissioning procedure

Kauppinen, Timo

2007-04-01

A Building Commissioning-project (ToVa) was launched in Finland in the year 2003. A comprehensive commissioning procedure, including the building process and operation stage was developed in the project. This procedure will confirm the precise documentation of client's goals, definition of planning goals and the performance of the building. It is rather usual, that within 1-2 years after introduction the users complain about the defects or performance malfunctions of the building. Thermography is one important manual tool in verifying the thermal performance of the building envelope. In this paper the results of one pilot building (a school) will be presented. In surveying the condition and energy efficiency of buildings, various auxiliary means are needed. We can compare the consumption data of the target building with other, same type of buildings by benchmarking. Energy audit helps to localize and determine the energy saving potential. The most general and also most effective auxiliary means in monitoring the thermal performance of building envelopes is an infrared camera. In this presentation some examples of the use of thermography in energy audits are presented.

The Energy Regulatory Commission (1). Law of the Comision Reguladora de Energia

International Nuclear Information System (INIS)

1995-01-01

The Energy Regulatory Commission. Reforms to the Electric Energy Public Service Law (1992) and the Regulatory Law of Article 27 on Petroleum (1995) have brought about fundamental changes in the electric and natural gas industries. The legal reforms explicitly permit the private sector to construct, operate, and own, systems of electric generation and natural gas transportation, storage and distribution. The participation of the private sector in these areas required a redefinition in the government regulatory institutions. Accordingly the Federal Congress enacted the law of the Comision Reguladora de Energia (CRE) in 1995. The CRE law expands the scope of the CRE's authority and the breadth of its powers beyond those established when it was initially created in 1993. The CRE commenced operations in January 1994 as a decentralized technical and consultative body of the Energy Ministry. The decree that created the Commission limited the scope of its authority to an analysis and consultative role applicable only to the electric industry. (Author)

During the operation of its facilities, the Valduc Research Center produces alpha-contaminated solid waste. An incineration facility has been built to treat the most contaminated combustible waste. The process selected for waste incineration is the IRIS process, which was developed by the CEA at the Marcoule Nuclear Research Center. The Valduc Center asked SGN to build the incineration facility. The facility was commissioned in late 1996, and inactive waste incineration campaigns were run during more than 2,500 hours in 1997-1998. Active commissioning of the facility was performed in March 1999. Since then five campaigns with active waste and a complete plutonium cleaning session have been carried out, the results of which are given in the paper. The Valduc incinerator is the first industrial active application of the IRIS process. (authors)

Israel Atomic Energy Commission 1996 Annual Report

International Nuclear Information System (INIS)

1996-01-01

Selecting the research efforts to be highlighted in the Israel Atomic Energy Commission's Annual Report from the large body and broad spectrum of ongoing work is not an easy task. The extensive bibliography of published results attached to the report attests to the scope of this difficulty. Of the many worthwhile projects, four were chosen to represent best the current trends in the continuing R and D program at the research centers of the Israel Atomic Energy Commission. One of these trends is the growing cooperation with private industry, in an attempt to gear our R and D programs to respond to market demands. Another feature, noted already several years ago, is the extensive collaboration of our scientists and engineers with colleagues at other institutions, in Israel and abroad. some of the work reported is part of evolving international industrial cooperation projects, illustrating both these trends. Following a trend common to many nuclear research centers around the world, a substantial part of our research effort is non-nuclear in nature. This is illustrated in the first article, which deals with advances in the application of non-linear optics in diverse fields of science and technology. These include state-of-the-art solid-state lasers, rapid modulation of light signals, development and generation of tunable sources of coherent light, optical data storage and the microscopic probing of biological and inorganic samples. The present work reports on a range of R and D, from the fundamentals of non-linear optical materials to proof-of-principle demonstrations of non-linear subwavelength resolution microscopy, to fabrication of prototype commercial tunable laser systems The second report considers the microstrain characteristics in some alloys using X-ray diffraction (XRD). The research utilizes XRD line broadening effects to study the characteristics of alloys from especially prepared surfaces. These characteristics include the homogeneity of alloying

2004-01-01

In February 2000, the German Bundestag established a Study Commission on 'Sustainable Energy Supplies in View of Globalisation and Liberalisation' (cf. Final Report, 2002). The Commission's Final Report is a contribution made by Germany toward implementing the sustainable development objectives defined in 1992 at the World Summit in Rio de Janeiro (Agenda 21). Despite minority votes of several members of the Study Commission, the main outcomes of the Final Report are worthwhile discussing in other industrial countries. The Commission had been given the mandate to identify 'robust, sustainable development paths' for the energy sector for the period up to 2050, which represent a scientific basis for the German parliament's further decision-making in the field of long-term energy policy. The applied backcasting approach showed that an ambitious climate-protection goal--reducing CO 2 emissions by 80% by 2050 - is technically and economically feasible. The main strategies and instruments for protecting the climate while ensuring a sustainable energy supply are summarised

After a comment of the Fukushima accident and its implications for nuclear energy, this issue proposes a critical review of various reports and scenarios on energy perspectives: a report by the ASN on 'Complementary safety assessments' (critical analysis of these assessments, weaknesses of the ASN analysis), a report by the French Court of Audit or 'Cour des Comptes' (past, current and future expenses, assets), the Commission Energies 2050 study (on the Europeans and world energy context, on the future on the French energy mix), a study by the French Union of Electricity (Electricity 2030: which choices for France?), a note by the CEA on the assessment of phasing out nuclear. Additional contributions propose a discussion of costs and conditions of phasing out nuclear, and a presentation of La Hague pools (their design, their management, their ability to withstand earthquakes, their other safety criteria)

Seismological studies carried out by the CEA in connection with the safety of nuclear sites

International Nuclear Information System (INIS)

Barbreau, A.; Ferrieux, H.; Mohammadioun, B.

1975-01-01

In order to evaluate the seismic risk at nuclear sites, the Department of Nuclear Safety of the French Atomic Energy Commission (CEA) has been conducting a programme of seismological studies for several years past. This programme is aimed at acquiring a better knowledge of seismic phenomena, in particular the spectral distribution of the energy of earthquakes, considered to be the only correct approach to the problem of earthquake protection, as well as a better knowledge of the seismic activity of the areas surrounding nuclear sites. The authors propose defining the design spectrum of the site on the basis of the probable energy at the source, the distance from the epicentre and the transfer function of the geological formations. The need - for the purpose of defining this spectrum - to acquire data on the characteristics of French earthquakes and on regional seismicity led the Department of Nuclear Safety to set up a network of seismic stations. It now has an observatory at the Cadarache Nuclear Research Centre and mobile stations with automatic magnetic recording for studying aftershock sequences and the activity of faults in the vicinity of nuclear sites, and for making the measurements necessary to calculate the transfer functions. With this equipment it was possible to record six aftershocks of the Oleron earthquake on 7 September 1972 close to the epicentre, and to calculate the spectra therefrom. The latter contained a lot of high frequencies, which is in agreement with the data obtained from other sources for earthquakes of low energy. The synthetic spectra calculated on the basis of one magnitude and one distance are in good agreement with the spectra obtained experimentally

Cancer imaging with CEA antibodies: historical and current perspectives.

Science.gov (United States)

Goldenberg, D M

1992-01-01

This article reviews the history and status of cancer imaging with radiolabeled antibodies against carcinoembryonic antigen (CEA). Although CEA and many other cancer-associated antigens are not distinct for neoplasia, the quantitative increase of these markers in malignant tissues provides a sufficient differential for selective antibody targeting. Animal studies with xenografted human tumors provided the first evidence of the prospects of this technology, followed by initial clinical success with purified goat whole IgG antibodies to CEA, labeled with 131I and with the use of dual-isotope subtraction methods. Subsequently, improved and earlier imaging could be accomplished with monoclonal antibody fragments, which then would permit the use of shorter-lived radionuclides, such as 111In, 123I, and 99mTc. The preferred use of a monoclonal anti-CEA IgG Fab' fragment, labeled with 99mTc by a recently developed, simple and rapid kit, has enabled the detection of small lesions, including those in the liver, within 4 h of injection. By means of SPECT imaging, a high sensitivity and specificity for RAID could be achieved.

Bezerra, Leonardo Ferreira

2017-01-01

The present study is a summative meta-evaluation that had as objective to evaluate the quality of the process of evaluation of individual performance of the servers of the National Commission of Nuclear Energy, being guided by the scientific curiosity to know to what extent the evaluation of performance the National Commission for Nuclear Energy meets the quality standards disseminated by the Joint Committee on Standards for Educational Evaluation. The methodology chosen to be used was based on the management approach and had as a guiding principle of the study the elaboration of a framework of criteria considering the aforementioned standards. The criteria established in the criteria framework guided the preparation of the items of the questionnaire sent to the National Commission of Nuclear Energy servers. In addition to the questionnaire, the observation of this author was considered in the context where the phenomenon occurred, which allowed a better reflective analysis of the data collected by the questionnaire. Regarding the results, it can be inferred that the performance evaluation developed at the National Commission of Nuclear Energy can be considered of quality, highlighting the servers' trust for the data, the communication process of the program stages, the credibility of the evaluators, the process of negotiation of goals and adaptability of the instrument over the course of the cycle. However, there are some opportunities for improvement, considering the relevance of evaluation as a tool to improve the performance of the autarchy's servers. Among the points that need to be improved is that there is currently a lack of knowledge about the legal basis and justification of the process of evaluation process by the servers and the lack of clarity regarding the content of the final evaluation report. Among the recommendations of this study, one can consider as the most relevant the need to: disseminate the results of this meta-evaluation to the

Aim: It is known that routine follow-up of patients with resected colorectal cancer includes serial CEA determinations. In this retrospective study we have investigated relationship between CEA level and survival and whether achieved results enable differentiation of tumors with slow and rapid growth. Material and Methods: Mainly between 1995 and 1999 periodic CEA determination by IRMA were performed in 269 patients after curative resection of colorectal carcinoma. Number of CEA determination/patient were 2-16(median 6). Survival ranged 4,5 and>249,7 months. Based on CEA results patients were divided in group with normal (<10ng/ml) and elevated (=10ng/ml) values regardless of postoperative treatment. Survival curves were computed by Kaplan-Meier method and difference was evaluated by logrank test and difference between proportions. Results:Normal end elevated CEA was found in 193 and 76 patients, respectively. The difference of survival curves between patients with normal and elevated CEA are highly significant (p<0,0001). However, only 10 months after tumor resection is the difference between survived proportions significant suggesting already presence of CEA produced micrometastases contributing to progression of neoplastic process. The mean survival time at normal and elevated CEA values are 142,54±17,86(median 128,60±24,04) and 34,15±4,28 (median 25,20±1,97) months, respectively. No significant difference of survival was found regarding tumor localization. Conclusion:The results show that with regard to CEA level it is possible to divide colorectal tumors on marker negative and positive. Marker negative are with slower growth and relatively good prognosis. Marker positive are associated with elevated CEA level and with considerable shorter survival. Postoperative CEA level is valuable parameter in prediction of patient's outcome

2012-01-01

The 'Energies 2050' Commission has studied 4 scenarios for energy policy: 1) a rapid passing to the third generation reactors by replacing existing reactors by EPR as soon as they reach 40 years, 2) the extension of the operating life to 60 years for the today operating reactors. 3) a progressive phaseout of nuclear energy by replacing only 1 reactor out of 2 who reach 40 years by an EPR, 4) a quick phaseout of nuclear energy by decommissioning reactors as soon as they reach 40 years and replacing them by renewable energies and fossil energies, These four scenarios have been studied along different aspects: the electricity cost, the needed investment, the CO 2 emissions, the impact on jobs, on trade balance, the security of the power supply. Concerning the cost of electricity production, the various scenarios give: 1) between 60 and 73 euros/MWh, 2) between 52 and 59 euros/MWh, 3) between 69 and 79 euros/MWh and 3) between 80 and 102 MWh. Concerning the impact on jobs, we have to notice that it depends very little on the scenario. A low cost of electricity is an important asset in the worldwide commercial competition. Lifetime extension appears to be the best scenario all the more, because it spares a lot of money and give renewable energies time to get mature. (A.C.)

The European Commission and IEA highlight the importance of diversifying energy sources

Europe will become more and more dependent on foreign sources for its energy supply because of the growing demand for energy. As a consequence Europe must diversify both its supplying countries and its energy sources. In this way the Nabucco gas pipeline project is important because it will link the Caspian sea to Europe by avoiding Russia, the main gas supplier of Europe. Other sources of energy like renewable energies or nuclear energy or carbon sequestration must be developed in Europe. Another point is to give more power to the European Commission to deal directly with energy exporting countries to get more favourable contracts, till now each member state has favored its own bi-lateral talks.

The serum carcinoembryonic antigen (CEA) level has been recognized as a prognostic factor in colorectal cancer, and associated with response of rectal cancer to radiotherapy. This study aimed to identify CEA-interacting proteins in colon cancer cells and observe post-irradiation changes in their expression. CEA expression in colon cancer cells was examined by Western blot analysis. Using an anti-CEA antibody or IgG as a negative control, immunoprecipitation was performed in colon cancer cell lysates. CEA and IgG immunoprecipitates were used for liquid chromatography–tandem mass spectrometry (LC-MS/MS) analysis. Proteins identified in the CEA immunoprecipitates but not in the IgG immunoprecipitates were selected as CEA-interacting proteins. After radiation treatment, changes in expression of CEA-interacting proteins were monitored by Western blot analysis. CEA expression was higher in SNU-81 cells compared with LoVo cells. The membrane localization of CEA limited the immunoprecipitation results and thus the number of CEA-interacting proteins identified. Only the Ras-related protein Rab-6B and lysozyme C were identified as CEA-interacting proteins in LoVo and SNU-81 cells, respectively. Lysozyme C was detected only in SNU-81, and CEA expression was differently regulated in two cell lines; it was down-regulated in LoVo but up-regulated in SNU-81 in radiation dosage-dependent manner. CEA-mediated radiation response appears to vary, depending on the characteristics of individual cancer cells. The lysozyme C and Rab subfamily proteins may play a role in the link between CEA and tumor response to radiation, although further studies are needed to clarify functional roles of the identified proteins.

Overview of Cea studies on hydrogen production and related prospects for nuclear power

International Nuclear Information System (INIS)

Agator, J.M.; Guigon, A.

2001-01-01

The anticipated growth of the world energy demand and the increasing concern about the emission of greenhouse gases, with the objectives of limitation fixed by the Kyoto protocol, provide the impetus for the development of hydrogenous fuels, and especially that of hydrogen as energy carrier. The trend will be reinforced in the longer term with the progressive shortage of natural hydrocarbon fuels. Fuel cells used in stationary, transport and portable applications will probably be the most efficient hydrogen converter and the most promising decentralized energy technology of the coming decades. In order to contribute to the reduction of greenhouse gas emissions, the massive use of hydrogen for transport and stationary applications calls for the development of production processes compatible with low CO 2 emissions, thus limiting the use of fossil fuels (natural gas, oil, coal, etc.) as reagent or energy sources. Furthermore, the progressive exhaustion of economic fossil fuel reserves will ultimately make it necessary to extract hydrogen from water through CO 2 -free processes. With this prospect in view, base-load nuclear energy, besides renewable energies, can play an important role to produce hydrogen through electrolysis in the medium term, as can high temperature thermo-chemical water dissociation processes in the longer term. Starting from current research in the field of fuel cells and hydrogen storage systems, the CEA intends to implement a large R and D programme on hydrogen, continuing previous research and covering the aspects of production, transport and related safety requirements. This endeavour is intended to reinforce the contribution of the CEA to the national and European research effort on non-fossil energy sources, and to create new opportunities of international collaboration and networking.

Fifty four patients, operated for colorectal cancer have been followed up for 2 to 100 months after surgery by carcino-embryonic antigen (CEA) determinations and classical, clinical, biological, radiological, echographical, isotopical and tomoscanninvestigations. Each new serum sample has been assayed for CEA with previously collected samples within the same patients. This repetition of CEA on the same samples allows to check the good reproducibility of CEA radioimmunoassay (variation coefficient between assay is less than 10%) and to get a complete profile of CEA level evaluation within the same assay. There is a good correlation between clinical evolution and CEA levels. In 42 patients, CEA levels remained or became normal ( 20 ng ml) at the same time or before clinical and/or paraclinical evidences for metastases or local recurrence. These results showed CEA assay in a quantitative parameter to assess the follow-up of colorectal cancer complementary to clinical, biological, radiological, echographical and isotopical criterias [fr

Tsaltas, G; Ford, C H; Gallant, M

1992-01-01

One of the important factors affecting the action of monoclonal antibodies (Mabs) or immunoconjugates on tumour sites depends on whether the Mab is internalized by the cancer cells in question. The underexplored subject of internalization is discussed in this paper, and a number of in vitro techniques for investigating internalization are evaluated, using a model which consists of a well characterized anti-carcinoembryonic antigen (anti-CEA) Mab and a number of CEA expressing human cancer cell lines. Employing two alternative radiolabeling assays, evidence for internalization of the anti-CEA Mab by a CEA-positive colorectal cancer cell line (LS174T) was obtained throughout the time intervals examined (5 min to 150 min). Electronmicroscopy employing horseradish-peroxidase labeled anti-CEA Mab and control antibody permitted direct visualization of anti-CEA Mab-related staining in intracellular compartments of a high CEA-expressor human colorectal cell line (SKCO1). Finally Western blots of samples derived from cytosolic and membrane components of solubilized cells from lung and colonic cancer cell lines provided evidence for internalized anti-CEA Mab throughout seven half hour intervals, starting at 5 minutes. Internalized anti-CEA was detected in all CEA expressing cell lines (LS174T, SKCO1, BENN) but not in the case of a very low CEA expressor line (COLO 320).

This article si devoted to the Cea site of the Bouchet. Radiation monitoring have been made and the information about it, given to the populations around the site. The wastes with a value upper than this one chosen for low activity wastes have been sent to the storage center of Manche plant, the other ones whom activity level was lower than this one advocated for low level radioactive wastes were used for the base of A87 motorway. The two little rivers have been cleaned out and the sediments tipped out in the decantation basin of the Cea site. Radiation monitoring for the radon have to be made to control the right progress of these decontamination operations. All these operations have been made in dialogue with S.N.P.E.( the national society of powders and explosives), the D.R.I.R.E.( regional direction of research industry and environment), O.P.R.I. (office of protection against ionizing radiations) and the Cea. (N.C.)

CEA celebrates the jubilee of ZOE reactor

International Nuclear Information System (INIS)

Loverini, M.J.

1998-01-01

This article reviews the saga of the first French nuclear reactor ZOE. As soon as 1939 Frederic Joliot had an intuition of the possibility of using fissioning nuclei to produce energy. 3 patents describing the concept of a nuclear reactor highlighting the role of natural uranium as fuel, heavy water as moderator, were registered. The only producer in the world of heavy water was a Norwegian firm, a fierce competition with Germany for the control of deuterium broke out. Eventually 185 Kg of heavy water were secretly convoyed in Great-britain. Because of the development of the war, the small scientist team in charge of the project has had to move from France to Great-britain then to Canada. At the end of the war, the 'Commissariat a l'energie atomique' (CEA) was created, its first aim was to design a nuclear reactor as soon as possible. In 1948 the first criticality of ZOE is reached, 6 years later than the team led by Enrico Fermi did in Chicago. In 1976 ZOE was decommissioned and is now a small museum dedicated to nuclear energy.

Full Text Available Introdução: Rosácea fulminante (RF ou pioderma facial é uma doença rara, descrita em 1940 por Kierland e O’Leary. É considerada uma variante extrema de rosácea conglobata, esta, consiste em formação de placas e abscessos hemorrágicos na pele. A RF tem sua etiologia desconhecida, porém há teorias que relacionam seu acometimento com a variação de hormônios femininos e a ingestão de vitamina B12. A RF é frequente em mulheres, principalmente pós- adolescentes. Apresenta-se abruptamente na face, amiúde na região mento- mandibular, através de pápulas inflamatórias, pústulas, cistos e nódulos com comedões escassos ou inexistentes, além de abcessos, sem manifestações sistêmicas e com a recidiva rara. Seu diagnóstico é fundamentalmente clínico, apenas com a história do paciente, sem necessidade de exames complementares. Para o tratamento, são utilizados corticoides orais, isotretinoína oral e antibióticos a fim de minimizar as sequelas físicas e psicológicas. Objetivo: Relatar caso de paciente com diagnóstico de rosácea fulminante. Metodologia: Paciente diagnosticada com rosácea fulminante atendida em serviço ambulatorial e revisão de literatura.

Network and system diagrams revisited: Satisfying CEA requirements for causality analysis

International Nuclear Information System (INIS)

Perdicoulis, Anastassios; Piper, Jake

2008-01-01

Published guidelines for Cumulative Effects Assessment (CEA) have called for the identification of cause-and-effect relationships, or causality, challenging researchers to identify methods that can possibly meet CEA's specific requirements. Together with an outline of these requirements from CEA key literature, the various definitions of cumulative effects point to the direction of a method for causality analysis that is visually-oriented and qualitative. This article consequently revisits network and system diagrams, resolves their reported shortcomings, and extends their capabilities with causal loop diagramming methodology. The application of the resulting composite causality analysis method to three Environmental Impact Assessment (EIA) case studies appears to satisfy the specific requirements of CEA regarding causality. Three 'moments' are envisaged for the use of the proposed method: during the scoping stage, during the assessment process, and during the stakeholder participation process

Leroy, Arnaud

2014-01-01

This report first recalls the objectives of the first Energy-Climate package and outlines that its implementation revealed some gaps despite some promising results. The author then notices that the current context requires new efforts, and that new objectives have been defined to promote energy transition: propositions of the European Commission are recalled as well as the opinions of the European Parliament and European Council. The author discusses the ambition of this second package as a lever for a transition towards a new growth model. He discusses divergence issues between countries, and the triple challenge (emission reduction, share of renewable energy, energy efficiency), and outlines that energy transition represents a new industrial project for Europe, and that the evolution towards a Union of energy is needed. Works of the French Commission for European Affairs are briefly reported, and the proposal for a European resolution is given

The financial incentives of European Commission to renewable energies

International Nuclear Information System (INIS)

Thomas, A.

2000-01-01

The European Commission has an active policy of favoring renewable energies but despite that, only one European program (ALTENER program) is completely dedicated to that topic, in fact various other programs allows the financing of projects concerning renewable energies. This article reviews various current programs that can offer such opportunities. ALTENER-1 was launched in 1993 and ALTENER-2 took over in 1998. ALTENER-2 is funded with 74 millions Euros for 5 years and can finance studies, pilot installations, information and training actions. 2 other programs ETAP and SYNERGY are also concerned by renewable or alternative energies. The fifth PCRD (research and development framing plan) is dedicated to problems of society and then can concern energy. PCRD is made up of 3 major programs (1-the international role of European research, 2-human potential and socio-economic research, 3-innovation and small and medium-scale enterprises) and 4 theme programs (1-energy, environment and durable development, 2-quality of life and management of life resources, 3-friendly information technologies and 4-growth and competitiveness. Each one of these 7 programs can finance actions concerning renewable energies but the first of the theme program is the best opportunity, it is funded with 2 milliards Euros for 5 years. (A.C.)

Ephraim, K.H.; Cox, P.H.; Hamer, C.J.A. v.d.; Berends, W.; Delhez, H.

1977-01-01

The carcinoembryonic antigen (CEA) is a complex of antigen determinants and also the carrier of these determinants. Chemically it is a glycoprotein. Its occurrence in blood serum or urine is correlated with malignant disease. Several radioimmunoassays (RIA) have been developed, one by Hoffmann-Laroche and one by the Rotterdam Radiotherapeutic Institute. Both methods and the Hoffmann assay kit are tested. Specifications are given for isolation of the antigen, preparation of the antiserum, and the execution of the RIA. Biochemical and clinical aspects are discussed

CA 19-9 as a marker in addition to CEA to monitor colorectal cancer.

Stiksma, Jolanda; Grootendorst, Diana C; van der Linden, Peter Willem G

2014-12-01

Carcinoembryonic antigen is the commonly used tumor marker in patients with colorectal cancer, and CA 19-9 might be an additional marker. The aim of this retrospective study was to investigate whether CA 19-9 levels can be used to monitor the disease process in patients with colorectal cancer who had no elevated CEA levels. The secondary aim was to determine if preoperative increased levels of CEA and CA 19-9 were associated with mortality. Two sets of data from patients with histologically confirmed colorectal cancer, were included in a single-center study. First, patients with a minimum of 3 serial measurements of CA 19-9 and CEA tumor markers were related to the clinical course of their disease. Second, patients with preoperative levels of CEA and CA 19-9 were related to survival. In patients with colorectal cancer and 3 serial measurements of tumor markers, 7.3% had only increased CA 19-9 levels without increased CEA levels, and 55.4% of the patients had an increase of CA 19-9 and CEA levels. In the patients with available preoperative markers, patients with only an increase of CA 19-9 had a significantly decreased 5-year survival compared with patients with an increase of only CEA (P = .013). CA 19-9 can be used as additional marker to follow the disease process in patients with colorectal cancer without an increase in CEA level. Patients with preoperative increased CA 19-9 level had a poorer 5-year survival than patients with preoperative increased CEA levels. Copyright © 2014 Elsevier Inc. All rights reserved.

U.S. Radioecology Research Programs of the Atomic Energy Commission in the 1950s

Energy Technology Data Exchange (ETDEWEB)

Reichle, D.E.

2004-01-12

This report contains two companion papers about radiological and environmental research that developed out of efforts of the Atomic Energy Commission in the late 1940s and the 1950s. Both papers were written for the Joint U.S.-Russian International Symposium entitled ''History of Atomic Energy Projects in the 1950s--Sociopolitical, Environmental, and Engineering Lessons Learned,'' which was hosted by the International Institute for Applied Systems Analysis in Laxemberg, Austria, in October 1999. Because the proceedings of this symposium were not published, these valuable historic reviews and their references are being documented as a single ORNL report. The first paper, ''U.S. Radioecology Research Programs Initiated in the 1950s,'' written by David Reichle and Stanley Auerbach, deals with the formation of the early radioecological research programs at the U.S. Atomic Energy Commission's nuclear production facilities at the Clinton Engineering Works in Oak Ridge, Tennessee; at the Hanford Plant in Richland, Washington; and at the Savannah River Plant in Georgia. These early radioecology programs were outgrowths of the environmental monitoring programs at each site and eventually developed into the world renowned National Laboratory environmental program sponsored by the Office of Biological and Environmental Research of the U.S. Department of Energy. The original version of the first paper was presented by David Reichle at the symposium. The second paper, ''U.S. Atomic Energy Commission's Environmental Research Programs Established in the 1950s,'' summarizes all the environmental research programs supported by the U.S. Atomic Energy Commission in the 1950s and discusses their present-day legacies. This paper is a modified, expanded version of a paper that was published in September 1997 in a volume commemorating the 50th anniversary symposium of the U.S. Department of Energy's Office of

The Laboratoire Electronique et Traitement de l'Information (LETI) of the Commissariat à l'Energie Atomique (CEA, Grenoble, France) has been involved in the development of infrared detectors based on HgCdTe (MCT) material for over 30 years, mainly for defence and security programs [1]. Once the building blocks are developed at LETI (MCT material process, diode technology, hybridization, …), the industrialization is performed at SOFRADIR (also in Grenoble, France) which also has its own R&D program [2]. In past years, LETI also developed infrared detectors for space astrophysics in the mid infrared range - the long wave detector of the ISOCAM camera onboard ISO - as well as in the far infrared range - the bolometer arrays of the Herschel/PACS photometer unit -, both instruments which were under the responsibility of the Astrophysics department of CEA (IRFU/SAp, Saclay, France). Nowadays, the infrared detectors used in space and ground based astronomical instruments all come from vendors in the US. For programmatic reasons - increase the number of available vendors, decrease the cost, mitigate possible export regulations, …- as well as political ones - spend european money in Europe -, the European Space Agency (ESA) defined two roadmaps (one in the NIR-SWIR range, one in the MWIR-LWIR range) that will eventually allow for the procurement of infrared detectors for space astrophysics within Europe. The French Space Agency (CNES) also started the same sort of roadmaps, as part of its contribution to the different space missions which involve delivery of instruments by French laboratories. It is important to note that some of the developments foreseen in these roadmaps also apply to Earth Observations. One of the main goal of the ESA and CNES roadmaps is to reduce the level of dark current in MCT devices at all wavelengths. The objective is to use the detectors at the highest temperature where the noise induced by the dark current stays compatible with the photon

Guidelines for residential commissioning

Energy Technology Data Exchange (ETDEWEB)

Wray, Craig P.; Walker, Iain S.; Sherman, Max H.

2003-01-31

Currently, houses do not perform optimally or even as many codes and forecasts predict, largely because they are field assembled and there is no consistent process to identify problems or to correct them. Residential commissioning is a solution to this problem. This guide is the culmination of a 30-month project that began in September 1999. The ultimate objective of the project is to increase the number of houses that undergo commissioning, which will improve the quality, comfort, and safety of homes for California citizens. The project goal is to lay the groundwork for a residential commissioning industry in California focused on end-use energy and non-energy issues. As such, we intend this guide to be a beginning and not an end. Our intent is that the guide will lead to the programmatic integration of commissioning with other building industry processes, which in turn will provide more value to a single site visit for people such as home energy auditors and raters, home inspectors, and building performance contractors. Project work to support the development of this guide includes: a literature review and annotated bibliography, which facilitates access to 469 documents related to residential commissioning published over the past 20 years (Wray et al. 2000), an analysis of the potential benefits one can realistically expect from commissioning new and existing California houses (Matson et al. 2002), and an assessment of 107 diagnostic tools for evaluating residential commissioning metrics (Wray et al. 2002). In this guide, we describe the issues that non-experts should consider in developing a commissioning program to achieve the benefits we have identified. We do this by providing specific recommendations about: how to structure the commissioning process, which diagnostics to use, and how to use them to commission new and existing houses. Using examples, we also demonstrate the potential benefits of applying the recommended whole-house commissioning approach to

Significance of the fuel cycle aspects in CEA studies on future nuclear systems

International Nuclear Information System (INIS)

Carre, F.; Thomas, J.B.; Boidron, M.

2001-01-01

Nuclear energy has unique assets to meet the requirements for a sustainable development in terms of economic competitiveness, environmental friendliness and natural resources saving. Future nuclear system studies conducted by the CEA aim at investigating and developing promising technologies for the medium and the long term for reactors, fuels and the fuel cycle to make nuclear power eligible as one of the major energy sources of the sustainable development. It also aims at maintaining at the best possible level the expertise and the technologies that the CEA will be able to bring to future national and international projects likely to meet market needs in the next decades, which are still uncertain both in terms of performances and time scale. Progress for future nuclear systems is principally sought in the following areas: reinforced economic competitiveness against other available electricity generation means, with a special emphasis put on reducing the investment cost; enhanced safety, especially through an increased resistance to core damages in case of severe accident, and whenever possible by dedicated strategies to exclude core melting; cleanliness through minimising the production of long lived radioactive waste; resource saving through an optimum utilisation of the available resources of fissile and fertile materials; enhanced resistance to proliferation risks; potentialities for other applications than electricity production.

In the interest of promoting the international exchange of technical expertise, the US Department of Energy’s Office of Emergency Operations (NA-40) and the French Commissariat à l'Energie Atomique et aux énergies alternatives (CEA) requested that the National Atmospheric Release Advisory Center (NARAC) of Lawrence Livermore National Laboratory (LLNL) in Livermore, California host a joint table top exercise with experts in emergency management and atmospheric transport modeling. In this table top exercise, LLNL and CEA compared each other's flow and dispersion models. The goal of the comparison is to facilitate the exchange of knowledge, capabilities, and practices, and to demonstrate the utility of modeling dispersal at different levels of computational fidelity. Two modeling approaches were examined, a regional scale modeling approach, appropriate for simple terrain and/or very large releases, and an urban scale modeling approach, appropriate for small releases in a city environment. This report is a summary of LLNL and CEA modeling efforts from this exercise. Two different types of LLNL and CEA models were employed in the analysis: urban-scale models (Aeolus CFD at LLNL/NARAC and Parallel- Micro-SWIFT-SPRAY, PMSS, at CEA) for analysis of a 5,000 Ci radiological release and Lagrangian Particle Dispersion Models (LODI at LLNL/NARAC and PSPRAY at CEA) for analysis of a much larger (500,000 Ci) regional radiological release. Two densely-populated urban locations were chosen: Chicago with its high-rise skyline and gridded street network and Paris with its more consistent, lower building height and complex unaligned street network. Each location was considered under early summer daytime and nighttime conditions. Different levels of fidelity were chosen for each scale: (1) lower fidelity mass-consistent diagnostic, intermediate fidelity Navier-Stokes RANS models, and higher fidelity Navier-Stokes LES for urban-scale analysis, and (2) lower-fidelity single

Deng, Kai; Yang, Li; Hu, Bing; Wu, Hao; Zhu, Hong; Tang, Chengwei

2015-01-01

Background Carcinoembryonic antigen (CEA) is commonly used as a serum tumor marker in clinical practice; however, its prognostic value for gastric cancer patients remains uncertain. This meta-analysis was performed to assess the prognostic value of CEA and investigate CEA as a tumor marker. Methods PubMed, EMBASE and other databases were searched for potentially eligible studies. Forty-one studies reporting the prognostic effect of pretreatment serum CEA expression in gastric cancer patients were selected. Data on 14651 eligible patients were retrieved for the meta-analysis. Based on the data extracted from the available literature, the hazard ratio (HR) and 95% confidence interval (CI) for an adverse prognosis were estimated for gastric cancer patients with elevated pretreatment serum levels of CEA (CEA+) relative to patients with normal pretreatment CEA levels (CEA-). Results The CEA+ patients had a significantly poorer prognosis than the CEA- patients in terms of overall survival (OS: HR 1.716, 95% CI 1.594 - 1.848, P 0.05). In the pooled analyses of multivariate-adjusted HRs, the results suggested that pretreatment serum CEA may be an independent prognostic factor in gastric cancer (OS: HR 1.681, 95% CI 1.425 - 1.982; DSS: HR 1.900, 95% CI 1.441 - 2.505; DFS: HR 2.579, 95% CI 1.935 - 3.436). Conclusion/Significance The meta-analysis based on the available literature supported the association of elevated pretreatment serum CEA levels with a poor prognosis for gastric cancer and a nearly doubled risk of mortality in gastric cancer patients. CEA may be an independent prognostic factor for gastric cancer patients and may aid in determining appropriate treatment which may preferentially benefit the CEA+ patients. PMID:25879931

Carcinoembryonic antigen (CEA) has been studied in the field of gynecologic malignancy to determine whether it can be used as a tumor marker for early detection of recurrence or evaluation of therapeutic results. From January 1985 through December 1989, a total of 239 cervical cancer patients were entered for an analysis of plasma CEA level in the group with cervical cancer compared to the control group consisting of 65 normal healthy women and 18 women with benign gynecologic disease. Plasma CEA levels appear to be directly related with the tumor extension and as stages advance, the incidence of patients with abnormal plasma CEA levels is increased. Also, there seems to be a little higher incidence of abnormal CEA levels in patients with adenocarcinomas or adenosquamous carcinoma but not statistically significant because of small number of patients. When the patients developed recurrence, plasma CEA levels are markedly elevated in the majority, particularly in patients with hepatic metastases. In conclusion, serial plasma CEA checks could be used to detect recurrence during follow-up after treatment of cervical cancer.

The ejection of a control element assembly (CEA) with high reactivity worth causes the sudden insertion of reactivity into the core. Immediately after the CEA ejection, the nuclear power of the reactor dramatically increases in an exponential behavior until the doppler effect becomes important and turns the reactivity balance and power down to lower levels. The 3-D CEA ejection analysis methodology has been developed using the multi-dimensional code coupling system, CHASER, which couples three dimensional core neutron kinetics code ASTRA, subchannel analysis code THALES, and fuel performance analysis code FROST using message passing interface (MPI). This paper presents the pin-by-pin level analysis result with the 3-D CEA ejection analysis methodology using the CHASER. The pin-by-pin level analysis consists of DNBR, enthalpy and Pellet/Clad Mechanical Interaction (PCMI) analysis. All the evaluations are simulated for APR1400 plant loaded with PLUS7 fuel. In this paper, the pin-by-pin analysis using the multidimensional core transient code, CHASER, is presented with respect to enthalpy, DNBR and PCMI for APR1400 plant loaded with PLUS7 fuel. For the pin-by-pin enthalpy and DNBR analysis, the quarter core for HFP case or 15 - 20 assemblies around the most severe assembly for part powers or HZP cases are selected. And PCMI calculation is performed for all the rods in the whole core during a conservative time period. The pin-by-pin analysis results show that the regulatory guidelines of CEA ejection accident are satisfied.

Superconductivity was hailed as the most important achievement of modern physics when it was discovered in 1911. Since then the enthusiasm has damped a bit because superconductivity still requires very low temperatures. This article gives an historical account of the application of superconductivity to the research programs and achievement of Cea (French atomic energy board). The first uses were dedicated to the design of superconducting magnets. We can note the delivery in 1989 of 246 quadrupolar magnets for bending particle beams for the HERA accelerator. As for the LHC (large hadron collider) project, Cea-Grenoble has a key role in the development of the cryogenic system and Cea-Saclay is responsible of the design of 400 quadrupolar magnets, it will have to fabricate 3 prototypes and the mass production will be made in Germany. A second sector involving superconductivity is thermonuclear devices through magnetic confinement. Tore-Supra has been for 10 years the only big fusion machine involving a superconducting system. In ITER all the coils necessary to the plasma confinement will be superconducting, it will represent 700 tons of superconducting wires. The research programs linked to the ITER project have led to the design of a new superconducting material: the niobium-tin (Nb 3 Sn). A third sector is medical imaging in which Cea is involved since the eighties. Cea-Saclay will home the Neurospin center whose purpose is to assess the limit of brain imaging from mice to man. Cea has to design magnets in the range of 11 tesla with a one meter broad clearance, the selected technology is that of superconducting magnets cooled by pressurized superfluid helium. (A.C.)

How to Add Value to your Business with CEA: A Practical Approach

Directory of Open Access Journals (Sweden)

Daniel Cardenas

2010-04-01

Full Text Available Companies are always trying to differentiate themselves from the rest of the pack by applying different strategies such as improving customer service, increasing the efficiency of their operations, or reducing their costs. Most of the time, however, these goals are competing against each other for scarce resources, and managers often need to decide to concentrate on one. A small company can effectively and simultaneously accomplish these goals for a fraction of the cost by implementing communications-enabled business processes or solutions, which are a set of technology components that add real-time networking functionality to applications. One particular implementation of this framework is the one provided by Coral CEA. Coral CEA is a business ecosystem anchored around CEA functionalities that are offered as building blocks, out-of-the-box components that link the capabilities and intelligence of networks platforms with the power of current applications to provide a new set of features and functionalities. In this article, we show how a small company called Rezact, located in the ski resort town of Mont-Tremblant, Quebec, successfully implemented CEA capabilities within its own operations using Coral CEA services.

Gastric cancer (GC) is the fifth leading cause of cancer and the third leading cause of cancer-related mortality globally. Human pepsinogens (HP) are considered promising serological biomarkers for the screening of atrophic gastritis (AG) and GC. HP are biochemically and immunochemically classified into two groups: pepsinogen I (PG I) and PG II. Carcinoembryonic antigen (CEA) is a glycoprotein, which is present in normal mucosal cells but increased amounts are associated with adenocarcinoma, especially colorectal cancer. CEA in combination with other tumour markers can be used in pre-operative staging and thereby assist in the planning of the type of surgery required and future management options. The purpose of this study was to diagnose test PG I and combination with tumor marker CEA in 32 patients suspected with GC. There was a significant difference in levels of CEA between GC group with non-GC with a value p <0.001. PGI sensitivity was 70.58% and specificity 93.3%. The sensitivity of PGI and CEA combination of 94.1% and specificity 80%. The area of AUC obtained was 92.7% at 95% confidence interval (82.7-100%). This AUC value indicated that the value of diagnostic accuracy of the PGI and CEA combinations of 92.7%.

Carcinoembryonic antigen (CEA) is one of the most widely used tumor markers, and its level is increased in 30-60% of patients with pancreatic cancer (PC). However, little is known about the implications of CEA as a prognostic marker in metastatic PC. The purpose of this study was to examine the usefulness of CEA levels as a prognostic marker in patients with metastatic PC. We conducted a retrospective cohort study using data from a computerized database. A total of 433 patients with metastatic disease were analyzed. Median overall survival (OS) was significantly shorter for patients with high CEA (>5 ng/ml) than with normal CEA (≤5 ng/ml) (6.8 vs. 10.3 months, respectively; p CEA level was an independent predictive factor for OS (hazard ratio [HR], 1.81; 95% confidence interval [CI], 1.45-2.26). In the high CEA group, OS in patients treated with combination chemotherapy was similar to that with single-agent chemotherapy (median, 7.1 vs. 6.8 months; HR for OS, 0.99; 95% CI, 0.71-1.40). The present results show that CEA level is an independent prognostic factor in patients with metastatic PC. A combination chemotherapy regimen may offer modest survival benefit in patients with high CEA. Copyright © 2016 IAP and EPC. Published by Elsevier B.V. All rights reserved.

Microscopical descriptions of the fission fragmentation developed at CEA Bruyeres (France)

International Nuclear Information System (INIS)

Sida, J. L.

2007-01-01

The fission process has been studied from 1939 but there is no full theoretical description of the process. Two approaches have been developped at CEA Bruyeres le Chatel (France) in the basis of microscopic calculations with the Gogny Force. The first one is based on mean field calculations of the fission parameters (Potential enegy landscape, inertial parameters). The evolution of the wave function of the system is followed from the saddle point to the scission line in an adiabatic dynamical approach in order to determine the fission fragment distributions [GOU04]. The second one used the theoretical nuclear database AMEDEE (http://www-phynu.cea.fr/science_en_ligne/carte_potentiels_microscopiques/carte_potentiel_nucleaire.htm) which includes the mean field potential of more than 7000 nuclei. A precise energy balance is done at the scission point in order to define the available energy for each possible fragmentation. A statistical model is than used to determine the fragments distributions [HEI06]. This work is an improvement of the statistical scission point model of Wilkins et al [WIL76]. The free parameters of the previous description have been reduced to the minimum and there is still one parameter value that define the scission configuration which is not used ass a free parameter but has been fixed for the systematic that will be presented. This two microscopical models will be presented and the results will be discussed and compared to experiments. We will also point on their possible use to realize data evaluation for the burn-up of minor actinides, wastes of nuclear plants. (Author)

Staab, H.J.; Glock, S.; Hornung, A.

1982-01-01

The clinical validity of carcinoembryonic antigen (CEA) determination with a new solid phase enzyme immuno assay using a monoclonal antibody (EIA-m) in comparison with a common CEA radioimmunoassay with polyclonal antisera (RIA) was investigated for primary diagnosis in 123 patients with various malignancies and in the postoperative followup of 83 patients with gastrointestinal cancers over a period of about one year. The normal range of the new CEA test in which CEA was directly measured without any further extraction, was calculated from the CEA distribution of 147 healthy blood donors and found to be 0-1.5 μg CEA/l. Besides a very fine reproducibility the CEA-m exhibited a pronounced specificity for CEA from patients with colorectal cancers compared with the RIA. Using a cut-off level of >=1.5 μg CEA/l serum with the EIA-m, the test gave a specificity of 76% with a sensitivity of 72% for preoperative serum specimen of 82 patients with colorectal cancers and a control group of 53 patients with nonmalignant gastrointestinal diseases. In this groups of patients the EIA-m was superior to the RIA test which had a sensitivity of 75% at a specificity of 62% using a threshold of >=2.0 μg CEA/l serum. In the followup studies 3 basic tendencies of the CEA time courses well distinguished from each other could be established for both CEA-Tests. Tumor progression, characterized by steadily increasing CEA levels were evident in 20/23 cases with recurrent disease while decreasing or essentially unchanged CEA levels correlated with NED status in the patients. Furthermore 3/23 cases with metastasis in the followup had initial CEA increases indicated by EIA-m, 3-5 months before this increase of the CEA values was evident with the RIA. Transient CEA elevations, not associated with malignant growth, were found less frequently with the new EIA-m compared to the RIA. (orig.) [de

The Jules Horowitz Reactor (JHR) is a new modern Material Testing Reactor (MTR) currently under construction at CEA Cadarache research centre in the south of France. It will be a major research facility in support to the development and the qualification of materials and fuels under irradiation with sizes and environment conditions relevant for nuclear power plants in order to optimise and demonstrate safe operations of existing power reactors as well as to support future reactors design. It will represent also an important research infrastructure for scientific studies dealing with material and fuel behaviour under irradiation. The JHR will contribute also to secure the production of radioisotope for medical application. This is a key public health stake. The construction of JHR which started in 2007 is going-on with target of commissioning by the end of 2017. The design of the reactor provides modern experimental capacity in support to R and D programs for the nuclear energy for the next 60 years. In parallel to the facility construction, the preparation of the future staff and of the organisation to operate the reactor safely, reliably and efficiently is an important issue. In this framework, many actions are in progress to elaborate: Ο the staffing and the organisational structure for the commissioning test phases and also for normal operation, Ο the documentation in support to the reactor operation (safety analysis report, general operating rules, procedures, instructions, ···), Ο the maintenance, in service and periodic test programs, Ο staff training programs by using dedicated facilities (simulator, ···) Ο commissioning test programs for ensuring that the layout of systems and subcomponents is completed in accordance with the design requirements, the specification performances and the safety criteria. These commissioning tests will also be helpful for transferring the knowledge on the installed systems to the operating group. This paper gives the

The linear accelerator of Saclay (ALS) has been the object of a commissioning permission given by decree by the French prime minister in October 8, 1965. It is submitted to the regime of basic nuclear facilities as defined in the decree no. 63-1228 from December 11, 1963. The French atomic energy commission (CEA) put down a request for the definitive decommissioning and dismantling of this facility on May 30, 2002. The duration foreseen for these operations is of 4 years. After the safety examination of the request by the DGSNR and the institute of radioprotection and nuclear safety (IRSN), a favorable and conformable advice has been given by the different ministries (health, finances and industry, ecology and sustainable development) and has led to this decree which precises the different protection measures to be implemented during the dismantling work.

Measurement of carcinoembryonic antigen (CEA) has been widely applied to detect recurrence, especially of colorectal carcinoma. The validity however, is still controversial. We investigated serial changes in CEA values to calculate whether the CEA doubling time and half-life time could predict metastatic progression or prognosis in colorectal carcinoma. Pre- and post-operative serial serum CEA contents were determined in 22 cases of colorectal cancer with or without metastasis. CEA values were determined by enzyme immunoassay (EIA). Patients were assigned depending upon survival time (within vs. more than 18 months after primary resection) for assessment of CEA doubling time. From the gradient of the semi-logarithmic CEA graph, the preoperative doubling time was calculated and the postoperative half-life time was estimated according to the diagnosis of metastases within 2 years after primary resection [metastasis (+) or (-)]. In spite of the effect of curative re-operation of metastatic lesions or of postoperative adjuvant chemotherapy, the CEA doubling time of the groups showed a relation with prognosis (p = 0.045, Student's t-test) when the patients were divided into >18 and time. The CEA half-life time of the groups without overlooked metastases was statistically longer than those with (mean +/- SD 8.01 +/- 2.07 and 4.33 +/- 1.11, respectively, p Clearance (k) showed a significant difference between the groups (p time appeared to be a less independent prognostic factor, whereas prolongation of the CEA half-life time might potentially suggest the existence of overlooked synchronous metastases from colorectal carcinoma.

Multiple Sources of Pressure for Change: The Barroso Commission and Energy Policy for an Enlarged EU

Directory of Open Access Journals (Sweden)

Jan Frederik Braun

2009-11-01

Full Text Available This article presents a preliminary analysis of how and why the role, work and status of the European Commission are changing in an enlarged European Union. It does so by focusing on multiple sources of pressure for change. These include: enlargement, new modes of governance, administrative reforms and changed leadership under Barroso. Combined, though not interlinked, these multiple sources of pressure are evidence of the increasing difficulty for the Commission to design and propose Community-wide answers to complex challenges in a more diverse Union. For this reason, the Commission under Barroso relies less on its traditional monopoly power to propose formal legislation and more on non-traditional modes of policy-making. Energy policy, especially its external dimension, constitutes a policy field that has been affected by enlargement, i.e. characterised by an increasing heterogeneity of needs and preferences among the member states. Not only does it resists Community-wide answers, it also allows the Commission, as an agent, to make use of bureaucratic drifts, i.e. exploit its strategic position in the EU’s governance system and use of a range of formal and informal resources of expertise. To deliver sustainable European added value to this complex policy area, however, the Commission must focus more on pragmatic policy results by making smart use of the EU’s increasing asymmetry, diversity and subsidiarity in a bottom-up approach. A non-legislative approach can serve as a modus vivendi to keep the momentum going in the Union’s difficult struggle to establish a workable energy regime.

Nuclear energy for space: Past CEA activities and ongoing OPUS studies

International Nuclear Information System (INIS)

Raepsaet, Xavier; Marion, Denis; Valentian, Dominique

2006-01-01

Since the beginning of space activities, solar and nuclear energy have been identified as the only available options for extended missions according to present knowledge. Both types have been used extensively for missions on Earth orbit, interplanetary space and planetary/lunar surface. However, the intensity of solar irradiation decreases with the square of the distance from the Sun. Future scientific and human explorations will take benefits of using a safe in-space nuclear reactor for providing both sufficient electric energy and efficient performance for a space propulsion. The first part of the paper presents a brief status of the different types of nuclear power sources, their characteristics and their field of applications. Previous CEA's projects of space nuclear fission reactors that have been studied in the past will also be discussed; the ERATO project in the 80's (design of a Nuclear Electric Propulsion system of 20 to 200 kWe) and the MAPS project in the 90's (definition of a Nuclear Thermal Propulsion system of 300 MWth for 72 kN of thrust). According to the recent road-maps, CEA decided to maintain a waking state in its spatial nuclear activities by carrying out some conceptual design studies of Nuclear Electric Power systems in the range of 100-500 kWe. The second part of the paper describes the main characteristics of this Optimized Propulsion Unit System (OPUS studies) and its different components. These characteristics, the basic options of the OPUS system that have been selected and the reasons associated to those choices are examined. Especially, the nuclear reactor has been defined considering the possible synergies with the next generation of terrestrial nuclear reactor (International Generation IV Forum). After two successive sets of studies, two different versions of this nuclear system have emerged. The first one is a fast, high-temperature helium cooled reactor, coupled to a direct reheated Brayton cycle. This version is technically the

Beam dynamics and commissioning of low and medium energy H- beam at Linac4

Satri, Masoomeh Yarmohammadi; Lombardi, Alessandra; Lamehi-Rachti , Mohammad

The First step of the CERN Large Hadron Collider injectors upgrade (LIU) project is Linac4. It accelerates H- ions to 160 MeV in an 80 m long accelerator housed in a tunnel 12 m underground, presently under construction. It will replace the present 50 MeV proton Linac2 as injector of the proton accelerator complex to increase the LHC luminosity. It consists of a 45 keV RF volume source, a twosolenoid Low Energy Beam Transport (LEBT), a 352.2 MHz Radio Frequency Quadrupole (RFQ) accelerating the beam to 3 MeV, a Medium Energy Beam Transport (MEBT) line. The MEBT houses a fast chopper to selectively remove unwanted micro-bunches in the 352 MHz sequence and avoid losses at capture in the CERN PSB (1 MHz). After chopping, the beam acceleration continues by a 50 MeV Drift Tube Linac (DTL), a 100 MeV Cell-Coupled Drift Tube Linac and a Pi-Mode Structure bringing the beam to the final energy of 160 MeV. Linac4 has been commissioned with a temporary source up to 12 MeV. The beam commissioning stages of Linac4 in LEBT...

Energy prospects of France at the 2020-2050 vista. Report of the Energy Commission presided over by Jean Syrota - Volume 1

International Nuclear Information System (INIS)

2008-01-01

This book makes a synthesis of the works carried out by the Energy commission, implemented in May 2006 by the Centre of Strategic Analysis and gathering the different actors in concern: representatives, social partners, national and European administrations, operators and industrialists, consumer associations, research organizations, etc.. A second volume is available which gathers the integrality of the five working group reports. This collective work fits inside a series of studies that the public authorities have periodically launched on the energy question. They have led to the elaboration of energy policies, still dominated by the hydrocarbon prices: ambitious and rigorous during high price eras, non-obstructive and relaxed during low price eras. Todays, the global warming dominates the energy policy. In this context, a large-scale and permanent new policy has become mandatory to reduce as quickly as possible the CO 2 emissions linked to the satisfaction of energy needs. It must definitely fit with the European framework as well. The Energy Commission recommends that France prevails upon the European Union to adopt a highly voluntaristic policy of greenhouse gases abatement at the 2050 prospects based on a fair share among the member states of the efforts to be achieved. This document includes a prospective analysis of the geopolitical situation, evaluates the technological efforts to come and lists some consistent action proposals for France and the European and national scale.

Commissioning is the process of verifying that a building's heating, ventilation, and air conditioning (HVAC) and lighting systems perform correctly and efficiently. Without commissioning, system and equipment problems can result in higher than necessary utility bills and unexpected and costly equipment repairs. This report reviews the benefits of commissioning, why it is a requirement for Leadership in Energy and Environmental Design (LEED) certification, and why building codes are gradually adopting commissioning activities into code.

CEA in activated macrophages. New diagnostic possibilities for tumor markers in early colorectal cancer.

Science.gov (United States)

Japink, Dennis; Leers, Mathie P G; Sosef, Meindert N; Nap, Marius

2009-08-01

Serum tumor markers show low sensitivity, making them unsuitable for early detection of cancer. Activated macrophages (AM) from peripheral blood can accumulate tumor marker substances and facilitate early detection in prostate cancer. Here it was investigated whether carcinoembryonic antigen (CEA)-containing macrophages (CEACM) can be used to detect colorectal cancer (CRC) at earlier stages than can serum CEA. Peripheral blood was collected from patients with CRC (n=48), inflammatory colorectal disease (n=5) and from healthy controls (n=18). After separating and labeling AM with CD14-APC/CD16-FITC, AM were intracellularly labeled with anti-CEA antibody and flow cytometrically analyzed. Serum CEA and C-reactive protein (CRP) were measured. The fraction-size of CEACM discriminated between controls and CRC patients, irrespective of AJCC stage (AJCC stage I-IV, pCEA values were significantly elevated in AJCC stage II, III and IV (p=0.02, 0.006 and <0.0001, respectively). Combining CEACM with CRP levels separated CRC from inflammatory colorectal disease. CEACM combined with CRP appears to have diagnostic potential in early CRC.

Objective: To study the applicability of combined determination of serum VEGF and CEA levels in the diagnosis of colorectal cancer as well as the relationship between VEGF level and stage of the disease. Methods: Serum VEGF (with ELISA) and CEA (with RIA) levels serum were detected in 28 patients with colorectal cancer of various stages and 29 controls. Results: The diagnostic positive rate was 53.6% (15/28), 39.3% (11/28), 71.4% (20/28) with CEA, VEGF and combined test for colorectal cancer, respectively. The serum VEGF levels in patients with advance colorectal cancer were significantly higher than those in patients with earlier stages diseases and controls, VEGF levels were positively correlated with CEA levels (P<0.05). Conclusion: Combined detection of the levels of serum VEGF and CEA could improve significantly the diagnostic positive rate in patients with colorectal cancer. (authors)

In 2011 CEA reported 100 events to the Authority for Nuclear Safety (ASN). 93 were graded 0 on the INES scale and 7 were graded 1. None of them had a significant impact on the staff health and the environment. 25% of these events concerned delays in the controls of safety equipment. In 2011 CEA had to manage several situations that led to a response of its crisis center: 1) the explosion of an oven belonging to the Socodei-Centraco company situated near the Marcoule Center, 2) the discovery of about 500 grenades from the first world war during digging out works in the Grenoble Center, 3) flooding due to heavy rains in the Cadarache Center, and 4) an intrusion attempt at the Cadarache Center.

R and D developments on the disposal of radioactive wastes recently carried out at CEA (France)

International Nuclear Information System (INIS)

Petit, J.C.

1993-01-01

Since the law of december 31, 1991 voted by the French Parliament, disposal in geological formations is not the sole option considered for the management of radioactive wastes. Scientists and engineers, notably within the 'Commissariat a l'Energie Atomique' (CEA), must investigate in parallel two other options, namely i. advanced separation of long-lived radioisotopes and transmutation, and ii. improvement of radioactive waste matrices and long-term storage. Still, the geological disposal of radioactive wastes, which has generated within the last decade an immense amount of Research and Development, remains a major proposed solution to the long-term management of transuranic and high-level wastes. In this paper, we will describe some of the Research and Development carried out within CEA, avoiding the industrial and engineering aspects of the issues dealt with. Rather, we will illustrate major points of our basic research, underlining in particular methodological considerations

Full Text Available Abstract Background We have recently published some work on CEA levels in hookah (also called narghile, shisha elsewhere and cigarette smokers. Hookah smokers had higher levels of CEA than non-smokers although mean levels were low compared to cigarette smokers. However some of them were also users of other tobacco products (cigarettes, bidis, etc.. Objectives To find serum CEA levels in ever/exclusive hookah smokers, i.e. those who smoked only hookah (no cigarettes, bidis, etc., prepared between 1 and 4 times a day with a quantity of up to 120 g of a tobacco-molasses mixture each (i.e. the tobacco weight equivalent of up to 60 cigarettes of 1 g each and consumed in 1 to 8 sessions. Methods Enhanced chemiluminescent immunometric technique was applied to measure CEA levels in serum samples from 59 exclusive male smokers with age ranging from 20–80 years (mean = 58.8 ± 14.7 years and 8–65 years of smoking (mean = 37.7 ± 16.8. 36 non-smokers served as controls. Subjects were divided into 3 groups according to the number of preparations; the number of sessions and the total daily smoking time: Light (1; 1; ≤ 20 minutes; Medium (1–3; 1–3; >20 min to ≤ 2 hrs and Heavy smokers (2–4; 3–8; >2 hrs to ≤ 6 hrs. Because of the nature of distribution of CEA levels among our individuals, Wilcoxon's rank sum two-sample test was applied to compare the variables. Results The overall CEA levels in exclusive hookah smokers (mean: 3.58 ± 2.61 ng/ml; n = 59 were not significantly different (p ≤ 0.0937 from the levels in non-smokers (2.35 ± 0.71 ng/ml. Mean levels in light, medium and heavy smokers were: 1.06 ± 0.492 ng/ml (n = 5; 2.52 ± 1.15 ng/ml (n = 28 and 5.11 ± 3.08 ng/ml (n = 26 respectively. The levels in medium smokers and non-smokers were also not significantly different (p ≤ 0.9138. In heavy smokers, the CEA levels were significantly higher than in non-smokers (p ≤ 0.0001567.

To localize gastrointestinal tumor, 31 patients were injected with 1.7-2.1 mCi I-131 anti-CEA baboon polyclonal antibody. Whole body imaging at 48, 72, and occasionally 96 hrs was performed with a Signa Camera (Technicare) peaked at 364 keV with 20% window. Additional spot views were usually obtained. No subtraction methods were used. All patients had surgical and pathological confirmation of the nuclear medicine studies. Labeled antibody images were positive in 15 (8 recurrent or metastatic colorectal, 2 gastric, 1 pancreatic, 1 primary colon, and 1 breast metastatic to chest wall). In 1, antibody images were positive for metastatic deposits in para-aortic lymph nodes, but negative for primary rectal tumor. True negative images were observed in 6; false negative images in 9 (4 liver metastases, 2 rectal, 1 pancreatic, 1 mesenteric lymph node metastasis, 1 bone metastasis). In all cases, no correlation existed between preoperative CEA serum levels and imaging. I-131 labeled anti-CEA polyclonal antibody imaging proved highly efficient in detecting gastric cancer (2/2) and moderately efficient in detecting recurrent colorectal cancer (8/15). On the other hand, the I-131 labeled polyclonal anti-CEA antibody imaging was of limited value in detecting colon cancer (1/9), pancreatic cancer (1/4) and metastatic liver disease

The purpose of this study was to assess the predictive effect of preoperative CEA and CA 19-9 levels on the prognosis of colorectal and gastric cancer patients. CEA and CA 19-9 were evaluated preoperatively in patients undergoing surgery for colorectal cancer (n=116) and gastric cancer (n=49). Patients with CEA levels CEA Group 1, 5-30 ng/mL as CEA Group 2 and >30 ng/ mL were classified as CEA Group 3. Similarly the patients with a CA 19-9 level 100 U/mL as Group and 3. TNM stages and histologic grades were noted according to histopathological reports. Patients with a TNM grade 0 or 1 were classified as Group A, TNM grade 2 patients constituted Group B and TNM grade 3 and 4 patients constituted Group C. Demographic characteristics, tumor locations and blood types of the patients were all recorded and these data were compared with the preoperative CEA and CA19-9 values. A significant correlation between CA 19-9 levels (>100 U/mL) and TNM stage (in advanced stages) was determined. We also determined a significant correlation between TNM stages and positive vlaues for both CEA and CA 19-9 in colorectal and gastric cancer patients. In comparison between CEA and CA 19-9 levels and age, gender, tumor location, ABO blood group, and tumor histologic grade, no significant correlation was found. Positive levels of both CEA and CA 19-9 can be considered to indicate an advanced stage in colorectal and gastric cancer patients.

Green energy - the road to a Danish energy system without fossil fuels. Summary of the work, results and recommendations of the Danish Commission on Climate Change Policy

Energy Technology Data Exchange (ETDEWEB)

2010-09-15

This summary report describes the main outcomes of the deliberations of the Danish Commission on Climate Change Policy. It includes a proposal for how Denmark can become independent of fossil fuels and, at the same time, meet the target of reducing greenhouse gases by 80%-95% compared with 1990. In addition, 40 specific recommendations for initiatives which will contribute to the realisation of the vision are presented. The documentation section of the overall report, which is only available in Danish, presents the Climate Commission's work in more detail, as well as a description of the comprehensive analyses on which the Climate Commission has based its recommendations. Finally, the background documents, which have been prepared at the request of the Climate Commission are available (in Danish) at the Commission's website, www.klimakommissionen.dk. We can both reduce Danish emissions of greenhouse gasses significantly, and make Denmark independent of fossil fuels. This will require a total conversion of the Danish energy system; conversion away from oil, coal and gas, which today account for more than 80% of our energy consumption, and to green energy with wind turbines and bioenergy as the most important elements. The cost of conversion may seem surprisingly low. The low cost means that not only can we maintain our present living standards, we can also have considerable economic growth, so that energy expenditures will constitute less of our budgets in the future than today. The reason the cost is not higher is primarily because we will not have to pay for overpriced fossil fuels and CO{sub 2} reductions, and we will be able to limit our energy consumption through efficiency improvements in all areas in the future. It is difficult to make predictions about the exact design of the green energy system of the future. However, in overall terms it could look like this: 1) Energy will be used far more efficiently, so that we can, for example, heat our houses

Uropathogenic E. coli Exploit CEA to Promote Colonization of the Urogenital Tract Mucosa

Attachment to the host mucosa is a key step in bacterial pathogenesis. On the apical surface of epithelial cells, members of the human carcinoembryonic antigen (CEA) family are abundant glycoproteins involved in cell-cell adhesion and modulation of cell signaling. Interestingly, several gram-negative bacterial pathogens target these receptors by specialized adhesins. The prototype of a CEACAM-binding pathogen, Neisseria gonorrhoeae, utilizes colony opacity associated (Opa) proteins to engage CEA, as well as the CEA-related cell adhesion molecules CEACAM1 and CEACAM6 on human epithelial cells. By heterologous expression of neisserial Opa proteins in non-pathogenic E. coli we find that the Opa protein-CEA interaction is sufficient to alter gene expression, to increase integrin activity and to promote matrix adhesion of infected cervical carcinoma cells and immortalized vaginal epithelial cells in vitro. These CEA-triggered events translate in suppression of exfoliation and improved colonization of the urogenital tract by Opa protein-expressing E. coli in CEA-transgenic compared to wildtype mice. Interestingly, uropathogenic E. coli expressing an unrelated CEACAM-binding protein of the Afa/Dr adhesin family recapitulate the in vitro and in vivo phenotype. In contrast, an isogenic strain lacking the CEACAM-binding adhesin shows reduced colonization and does not suppress epithelial exfoliation. These results demonstrate that engagement of human CEACAMs by distinct bacterial adhesins is sufficient to blunt exfoliation and to promote host infection. Our findings provide novel insight into mucosal colonization by a common UPEC pathotype and help to explain why human CEACAMs are a preferred epithelial target structure for diverse gram-negative bacteria to establish a foothold on the human mucosa.

Objective: To investigate the clinical usefulness of determination of serum SA, CEA and CRP levels in patients with colorectal cancer. Methods: Serum SA (with colorimetry), CEA (with CLIA) and CRP (with ILIA) levels were measured in 120 patients with colo-rectal cancer. Results: (1) Serum SA, CEA and CRP levels increased significantly as the disease stage advanced from Duke A through Duke D. (2) As the malignancy of the growth advanced from well-differentiated to anaplastic, the serum SA and CRP levels increased significantly while the reverse was true for serum CEA levels. (3) In 68 post-operative patients followed 1-5 years, the serum levels of SA, CEA and CRP were significantly higher in the patients with recurrence (n=29) than those in patients without recurrence (n=39) (P<0.01). Conclusion: Serum SA CEA and CRP levels were closely related to the disease process in patients with colo-rectal cancer. (authors)

Okada, H.; Souza, I.T.T.; Silva, C.P.G.

1990-11-01

The purpose of this study is to examine a convenient system that can be used to iodinate monoclonal antibodies which is rapid, simple, efficient and reproducible, and which can be accomplished in radiopharmaceutical laboratories. It is important to remember that antibodies are sensitive biochemicals, subject to losses of the activity that is essential to their mode of action, namely the ability to bind specific antigen. The advent of solid phase iodination agents has greatly expanded the range of gentle iodination techniques available for iodinating sensitive biological materials. The agent most widely used is the Iodogen (1,3,4,6 tetrachloro-3a-6a diphenylglycoluril) method. Anti-CEA 4C sub(11) IgG sub(2a,k) (prepared in the Ludwig Institute-Sao Paulo-Brazil ) is used as model to evaluate the Iodogen methodology. The miniature chromatographic system, also rapid, accurate, simple, efficient was elaborated to determine the labelling efficiency incorporation of iodine into immunoglobulin, and the radiochemical purity of sup(131)I-anti-CEA.

Comparison of Ablation Predictions for Carbonaceous Materials Using CEA and JANAF-Based Species Thermodynamics

Science.gov (United States)

Milos, Frank S.

2011-01-01

In most previous work at NASA Ames Research Center, ablation predictions for carbonaceous materials were obtained using a species thermodynamics database developed by Aerotherm Corporation. This database is derived mostly from the JANAF thermochemical tables. However, the CEA thermodynamics database, also used by NASA, is considered more up to date. In this work, the FIAT code was modified to use CEA-based curve fits for species thermodynamics, then analyses using both the JANAF and CEA thermodynamics were performed for carbon and carbon phenolic materials over a range of test conditions. The ablation predictions are comparable at lower heat fluxes where the dominant mechanism is carbon oxidation. However, the predictions begin to diverge in the sublimation regime, with the CEA model predicting lower recession. The disagreement is more significant for carbon phenolic than for carbon, and this difference is attributed to hydrocarbon species that may contribute to the ablation rate.

2009-09-01

Full Text Available Background and objective Serum levels of tumor markers are associated with tumor metabolism or apoptosis, changes of which after chemotherapy may reflect tumor response to treatment. The aim of this study was to assess the predictive role of changes in serum levels of carcinoembryonic antigen (CEA and cytokeratin 19 fragment (CYFRA 21-1 during chemotherapy in patients with advanced non-small cell lung cancer. Methods Changes in serum levels of CEA and CYFRA 21-1 were investigated retrospectively after one cycle of chemotherapy in 42 patients with advanced NSCLC. Correlations between the changes and radiological objective response were analyzed. Results After two cycles of chemotherapy, radiological objective response rate was 28.6%. At baseline, gender, age, clinical stage, serum levels of CEA and CYFRA 21-1 were not different between patients with objective response (OR and no response (NR. After one cycle of chemotherapy, compared to baseline level, declines in serum levels of CEA and CYFRA 21-1 were observed in patients with OR, but have no statistical significance. In contrast, reduction of CEA and CYFRA 21-1 over baseline after one cycle of chemotherapy showed statistically significant difference between OR and NR. When reduction percentages of CEA and CYFRA 21-1 were used to predict objective response of chemotherapy, the area under the ROC curve (AUC was 0.875 for CEA and 0.919 for CYFRA 21-1. According to the ROC curve, a 22% reduction of CEA yielded a sensitivity of 58.3% and a specificity of 97%, 51% reduction of CYFRA 21-1 with a sensitivity of 83.3% and a specificity of 93.3%. When above reduction percentages were used as cutoffs for prediction of radiological objective response, combination of the CEA and CYFRA 21-1 yielded a sensitivity of 91.7% and a specificity of 86.7%. Conclusion Reduction percentages of CEA and CYFRA 21-1 during chemotherapy could be used to evaluate chemotherapy efficacy in patients with advanced NSCLC. The

Thermal-hydraulic investigations on the CEA-ENEA DEMO relevant helium cooled poloidal blanket

International Nuclear Information System (INIS)

Dell'Orco, G.; Polazzi, G.; Vallette, F.; Proust, E.; Eid, M.

1994-01-01

The CEA-ENEA design of an Helium Cooled Solid Breeder Blanket (HCSBB) for the DEMO reactor, with a breeder in tube (BIT) poloidal arrangement, is based on the use of lithium ceramic pellets, the ENEA γ-LiAlO 2 or the CEA Li 2 ZrO 3 . Due to the geometry of the DEMO reactor plasma chamber, these breeder bundles are adapted to the Vacuum Vessel with a strong poloidal curvature. This curvature influences the thermal-hydraulic behaviour of the coolant flowing inside the bundle. The paper presents the CEA-ENEA first results of the experimental and theoretical programme, aiming at optimizing the breeder module thermal hydraulic design. (author) 6 refs.; 7 figs.; 1 tab

In the framework of the ITER broader approach, the International Fusion Materials Irradiation Facility (IFMIF) deuteron accelerator (2 × 125 mA at 40 MeV) is an irradiation tool dedicated to high neutron flux production for future nuclear plant material studies. During the validation phase, the Linear IFMIF Prototype Accelerator (LIPAc) machine will be tested on the Rokkasho site in Japan. This demonstrator aims to produce 125 mA/9 MeV deuteron beam. Involved in the LIPAc project for several years, specialists from CEA/Saclay designed the injector based on a SILHI type ECR source operating at 2.45 GHz and a 2 solenoid low energy beam line to produce such high intensity beam. The whole injector, equipped with its dedicated diagnostics, has been then installed and tested on the Saclay site. Before shipment from Europe to Japan, acceptance tests have been performed in November 2012 with 100 keV deuteron beam and intensity as high as 140 mA in continuous and pulsed mode. In this paper, the emittance measurements done for different duty cycles and different beam intensities will be presented as well as beam species fraction analysis. Then the reinstallation in Japan and commissioning plan on site will be reported

1983-01-01

In the framework of their common program, CEA and FRAGEMA have undertaken the mechanical modelization of PCI. In the first step two different codes, TITUS and VERDON, have been tested by FRAGEMA and CEA respectively. Whereas the two codes use a finite element method to describe the thermomechanical behaviour of a fuel element, input models are not the same for the two codes: to take into account the presence of cracks in UO 2 , an axisymmetric two dimensional mesh pattern and the Druecker-Prager criterion are used in VERDON and a 3D equivalent method in TITUS. Two rods have been studied with these two methods: PRISCA 04bis and PRISCA 104 which were ramped in SILOE. The results show that the stresses and strains are the same with the two codes. These methods are further applied to the complete series of the common ramp test rods program of FRAGEMA and CEA. (author)

2016-01-01

Full text: Since the term“knowledge management”was coined, it has gained more and more attention in an effort to re-structure organizations. A good deal of effort has been done in order to better implement a knowledge management culture in organizations throughout all the work sectors. The Brazilian Federal Government through the Decree no.5.707, dated February 23, 2006, democratically created a national policy for human development. This initiative made equally available additional education opportunities for all staff in order to form a competent workforce which included official recognition of work-related skills. In the field of nuclear energy, the National Nuclear Energy Commission is a Brazilian governmental authority which has long served as the leader in the matter. In this respect, and in the light of the International Atomic Energy Agency (IAEA) nuclear knowledge management role and the perspective of the first and third dimensions, the aim of this paper is to share the outcome of the Government programme in the National Nuclear Energy Commission.

To study the diagnostic value of radioimmunoassay (RIA) of carcinoembryonic antigen (CEA) and ferritin the level of this markers under lung cancer depending on the tumor localization and the process stage is determined. It is shown that determination of CEA and ferritin level in a number of patients with the peripheral lung cancer allows on the confirm the diagnosis. In case of the central cancer an increase of CEA level testifies to the tumor germination into the adjacent organs and lung tissue and allows one to determine the stage and operability of the disease. 10 refs.; 3 tabs

High-risk patients with stage II colon cancer may benefit from adjuvant chemotherapy, but identifying this patient population can be difficult. We assessed the prognosis value for predicting tumor progression in patients with stage II colon cancer, of a panel of 2 biomarkers for colon cancer: tumor budding and preoperative carcinoembryonic antigen (CEA). Consecutive patients (N = 134) with stage II colon cancer who underwent curative surgery from 2000 to 2007 were included. Multivariate analysis was used to evaluate the association of CEA and tumor budding grade with 5-year disease-free survival (DFS). The prognostic accuracy of CEA, tumor budding grade and the combination of both (CEA-budding panel) was determined. The study found that both CEA and tumor budding grade were associated with 5-year DFS. The prognostic accuracy for disease progression was higher for the CEA-budding panel (82.1%) than either CEA (70.9%) or tumor budding grade (72.4%) alone. The findings indicate that the combination of CEA levels and tumor budding grade has greater prognostic value for identifying patients with stage II colon cancer who are at high-risk for disease progression, than either marker alone.

Studies of nuclear workers make it possible to directly quantify the risks associated with ionizing radiation exposure at low doses and low dose rates. Studies of the CEA (Commissariat à l'Energie Atomique) and AREVA Nuclear Cycle (AREVA NC) cohort, currently the most informative such group in France, describe the long-term risk to nuclear workers associated with external exposure. Our aim is to assess the risk of mortality from solid cancers among CEA and AREVA NC nuclear workers and its association with external radiation exposure. Standardized mortality ratios (SMRs) were calculated and internal Poisson regressions were conducted, controlling for the main confounding factors [sex, attained age, calendar period, company and socioeconomic status (SES)]. During the period 1968-2004, there were 2,035 solid cancers among the 36,769 CEA-AREVA NC workers. Cumulative external radiation exposure was assessed for the period 1950-2004, and the mean cumulative dose was 12.1 mSv. Mortality rates for all causes and all solid cancers were both significantly lower in this cohort than in the general population. A significant excess of deaths from pleural cancer, not associated with cumulative external dose, was observed, probably due to past asbestos exposure. We observed a significant excess of melanoma, also unassociated with dose. Although cumulative external dose was not associated with mortality from all solid cancers, the central estimated excess relative risk (ERR) per Sv of 0.46 for solid cancer mortality was higher than the 0.26 calculated for male Hiroshima and Nagasaki A-bomb survivors 50 years or older and exposed at the age of 30 years or older. The modification of our results after stratification for SES demonstrates the importance of this characteristic in occupational studies, because it makes it possible to take class-based lifestyle differences into account, at least partly. These results show the great potential of a further joint international study of

Linac4, the future 160 MeV Hˉ injector to the CERN Proton Synchrotron Booster, is presently under construction at CERN as a first step of the planned upgrade of the LHC injectors. The low energy section of LINAC4, consisting of an ion source, a 352.2 MHz Radio Frequency Quadrupole (RFQ) and a chopper line is being commissioned in a dedicated test stand before installation in its final position in the tunnel. The RFQ is designed to accelerate a 45 keV, 70 mA, Hˉ beam to 3 MeV, with an efficiency of 95% while preserving the transverse emittance. The RFQ, a four-vane structure 3 m in length, has been designed in collaboration with CEA/IRFU and is has been fabricated at the CERN workshop. The precise fabrication has allowed achieving a field flatness of 1%. The completion of the accelerating structure in September 2012 was followed by a complete series of bead-pull measurements and by high-power conditioning to the nominal power of 0.39 MW corresponding to a voltage of 78 kV across the 3 meters.

Evaluation of detection methodology for carcinoembryonic antigen and application of CEA in diagnosis of gastric cancer

International Nuclear Information System (INIS)

Wang Enlan; Li Tao

2005-01-01

To compare the specificity and sensitivity of different methods in detection of CEA, and to investigate the application of CEA detection in diagnosis of gastric cancer, CEA in serum of 36 patients with gastric cancer and 20 negtive reference serum was detected by ELISA, TR- FIA, RIA and CLIA. The results showed that the specificity of these 4 methods was all 100% and the sensitivity of ELISA was the lowest (19.4%) while CLIA was the highest (44.4%). Therefore, the sensitivity of ELISA should be raised and CEA, besides used as an observation index for curative effects in a part of gastric cancer patients, can not be used in diagnosis of gastric cancer.

The security of energy supply. The European Commission's Green Paper stimulates debate

International Nuclear Information System (INIS)

2000-01-01

The growing dependence of the European Union (EU) on external supplies of energy is the central focus of a ''Green Paper'' issued in late November 2000 by the Commission of the European Communities in Brussels. Entitled ''Towards a European Strategy for the Security of Energy Supply'', the Green Paper is intended to stimulate debate on the EU's energy policies and strategies. European member States are ''interdependent'', the Green Paper states, ''both because of climate change issues and the creation of the internal energy market. Any energy policy decision taken by a Member State will inevitably have repercussions on the functioning of the market in other Member States. Energy policy has assumed a new, Community dimension.'' Three main points emerge from the Green Paper: The EU will become increasingly dependent on external energy sources; its enlargement will not change this situation. Based on current forecasts, energy dependence will reach 70% by the year 2030. - The EU has very limited scope to influence energy supply conditions; it is essentially on the demand side that the EU can intervene, mainly by promoting energy saving in buildings and the transport sector. - The EU presently is not in a position to respond to the challenge of climate change and to meet its commitments, notably under the Kyoto Protocol.

2006-01-01

In the framework of the French V/HTR fuel development and qualification program, the Commissariat a l'Energie Atomique (CEA) and AREVA through its program called ANTARES (Areva New Technology for Advanced Reactor Energy Supply) conduct R and D projects covering the mastering of UO 2 coated particle and fuel compact fabrication technology. To fulfill this task, a review of past knowledge, of existing technologies and a preliminary laboratory scale work program have been conducted with the aim of retrieving the know-how on HTR coated particle and compact manufacture: - The different stages of UO 2 kernel fabrication GSP Sol-Gel process have been reviewed, reproduced and improved; - The experimental conditions for the chemical vapour deposition (CVD) of coatings have been defined on dummy kernels and development of innovative characterization methods has been carried out; - Former CERCA compacting process has been reviewed and updated. In parallel, an experimental manufacturing line for coated particles, named GAIA, and a compacting line based on former CERCA compacting experience have been designed, constructed and are in operation since early 2005 at CEA Cadarache and CERCA Romans, respectively. These two facilities constitute the CAPRI line (CEA and AREVA PRoduction Integrated line). The major objectives of the CAPRI line are: - to recover and validate past knowledge; - to permit the optimisation of reference fabrication processes for kernels and coatings and the investigation of alternative and innovative fuel design (UCO kernel, ZrC coating); - to test alternative compact process options; - to fabricate and characterize fuel required for irradiation and qualification purpose; - to specify needs for the fabrication of representative V/HTR TRISO fuel meeting industrial standards. This paper presents the progress status of the R and D conducted on V/HTR fuel particle and compact manufacture by mid 2005. (authors)

Full text: The classic radioimmunotherapy is based on transporting to the tumor, the necessary activity of a therapeutic isotope using a monoclonal antibody (MAb) against tumor associated antigen, which constitutes an ideal vehicle given its inherent specificity. In this sense, the immunoglobulin (Ig) has some severe practical limitations due to its unhappy pharmacokinetics, relatively high molecular weight (150 kDa) and slower clearance. Likewise the Ig molecule presents a poor diffusion through the tumor mass and a relative high immunogenicity. The solution to these problems has been offered by genetic engineering, methods where the multivalent recombinant fragments have become the paradigm of design of constructed molecules. They are able to retain the specificity of the parental antibody and affinity, with reduced immunogenicity and improved pharmacokinetics. The monoclonal antibody ior-CEA1 has been employed for the diagnosis of primary tumors, recurrences and metastatic disease, and has also been used extensively in the daily clinical practice as well. Inserted in this rebirth of the antibodies, this report explores the use of a new smaller molecular weight multivalent analogue of the parent ior-CEA1 antibody to be used for the diagnosis and therapy of CEA-expressing malignant tumors such as colorectal, lung, ovary among others. The dimeric scFv-ior- CEA1 construct was produced in the Centre for Genetic Engineering and Biotechnology and displayed to bind CEA epitope with a similar binding affinity to that of the murine IgG. Method: Labelling was achieved using Chloramine T, with a molar ration of Chloramine T:Tyrosine of 2.5. For the comparison of the immunoreactivity of labeled and unlabelled diabodies, was plotted the specific union vs the antibody concentration for both molecules and adjusted to a straight line. The immunoreactivity was also assayed using size-exclusion FPLC to evaluate their antigen-binding capacities after radiolabelling. Seventy

Background and aims: Pancreatic cyst fluid (PCF) CEA has been shown to be the most accurate preoperative test for detection of cystic mucinous neoplasms (CMNs). This study aimed to assess the added value of PCF KRAS mutational analysis to CEA for diagnosis of CMNs. Patients and methods: This is a retrospective study of prospectively collected endoscopic ultrasonography (EUS) fine-needle aspiration (FNA) data. KRAS mutation was determined by direct sequencing or equivalent methods. Cysts were classified histologically (surgical cohort) or by clinical (EUS or FNA) findings (clinical cohort). Performance characteristics of KRAS, CEA and their combination for detection of a cystic mucinous neoplasm (CMN) and malignancy were calculated. Results: The study cohort consisted of 943 patients: 147 in the surgical cohort and 796 in the clinical cohort. Overall, KRAS and CEA each had high specificity (100 % and 93.2 %), but low sensitivity (48.3 % and 56.3 %) for the diagnosis of a CMN. The positivity of KRAS or CEA increased the diagnostic accuracy (80.8 %) and AUC (0.84) significantly compared to KRAS (65.3 % and 0.74) or CEA (65.8 % and 0.74) alone, but only in the clinical cohort (P < 0.0001 for both). KRAS mutation was significantly more frequent in malignant CMNs compared to histologically confirmed non-malignant CMNs (73 % vs. 37 %, P = 0.001). The negative predictive value of KRAS mutation was 77.6 % in differentiating non-malignant cysts. Conclusions: The detection of a KRAS mutation in PCF is a highly specific test for mucinous cysts. It outperforms CEA for sensitivity in mucinous cyst diagnosis, but the data does not support its routine use. PMID:27092317

Lung cancer is sometimes difficult to differentiate from benign lung diseases expressing nodular shadow in imaging study. We assessed the diagnostic value of two commonly used tumor markers in distinguishing primary lung cancer from benign lung disease. The serum levels of carcinoembryonic antigen (CEA) and cytokeratin 19 fragments (CYFRA 21-1) were retrospectively analyzed in 655 lung cancer patients and 237 patients with benign lung disease. The standard cut-off levels of 3.2 ng/mL CEA and 3.5 ng/mL CYFRA 21-1 and twice these respective levels (6.4 ng/mL and 7.0 ng/mL) were used. CEA and CYFRA 21-1 levels were elevated in 32% and 11% of benign lung disease patients, respectively. CEA sensitivity and specificity for lung cancer diagnosis was 69% and 68% respectively, while that for CYFRA 21-1 was 43% and 89%, respectively. Thus, the combined value for the specificity of the two tumor markers was greater than either alone. Patients were grouped depending on their hospital status, and prevalence rates were determined. The prevalence rate of lung cancer in admitted patients was 51%, the prevalence rate of lung cancer in outpatients was 12%, and the prevalence rate of lung cancer identified during health check-ups was 0.1%. Positive predictive values (PPVs) were calculated using Bayes' theorem, and varied with the serum tumor marker and prevalence rate: PPVs of CEA [prevalence rate] were 69.2% [51%], 22.7% [12%], and 0.22% [0.1%], while PPVs of CYFRA 21-1 were 80.3% [51%], 34.8% [12%], and 0.39% [0.1%]. However, PPVs for lung cancer diagnosis at a prevalence rate of 51% were 87.3% or higher when the patient exhibited positive CEA and CYFRA 21-1, or CEA or CYFRA 21-1 levels twice the standard cut-off. Our results indicate that CEA and CYFRA 21-1 are reliable serum tumor markers for the diagnosis of lung cancer in addition to CT scans when combined or used individually at twice the standard cut-off level in high prevalence rate groups. The prevalence rate should

Dismantling and waste management: CEA's strategy and research programs

There are 3 main dismantling operations in CEA. First, the dismantling of the UP1 facility in the Marcoule site. UP1 was a reprocessing plant of nuclear fuels that operated from 1958 to 1997 and is now the biggest dismantling operation in the world. Its dismantling operation follows a 6-step scheme that will end in 2050. Secondly, the Passage project on the Grenoble site that concerns the dismantling of 3 research reactors (Siloette, Melusine and Siloe), of a laboratory dedicated to the analysis of active materials (Lama) and of a station for the processing of waste (Sted). Thirdly the Aladin project that concerns the installations of the Fontenay-aux-Roses site. The dismantling operations are complex because all the first research programs on high activity chemistry and on transuranium elements were performed in Fontenay-aux-Roses facilities and because ancient activities have to leave a clean place to be replaced by new ones. The radioactive waste produced by CEA enter the flow of waste that is normally processed and managed by ANDRA. Only high-activities waste have not yet a definitive solution, they are stored in waiting the opening of a geological repository. CEA leads research programs on the separation and transmutation of minor actinides and on the long-term behaviour of waste packages put in deep geological layers. (A.C.)

Ior-CEA-1: Labelling, quality control and clinical evaluation

1998-01-01

Within the Co-ordinated Programme on Labelling, Quality Control and Evaluation of Monoclonal Antibodies, the IAEA has made a great effort to expand efficient labelling methods, mainly those with radioisotopes which have been used for radioimmunoscintigraphy. In this sense, more recently 99 Tc m has been mostly employed in the majority of the investigations due to its ideal physical characteristics. Efficient labelling of monoclonal antibodies depends on a number of factors including the method and way of the label incorporation into the protein. During the last years several direct labelling approaches have been developed, which led to attain simple and inexpensive methods for medical practice, as well as safe and stable techniques which bring accurate and good quality images. Accordingly, this paper describes the results obtained during last five years which come from the comparison among different labelling systems, passing through the quality control to test the labelled monoclonal stability and the protein bioreactivity, to continue in the clinical evaluation of ior-CEA-1, as well as the evaluation of other antibodies. Up to now we have evaluated more than 70 patients with the anti-CEA monoclonal antibody (ior-CEA-1), examined in different clinical assays such as: pilot, phase I-II and extensive phase III-IV trials, whose results are encouraging. It confirms that the employed labelling approach was safe and adequate

2008-01-01

The two volumes of the Energy prospects of France at the 2020-2050 vista present the works carried out by the Energy commission, implemented in May 2006 by the Centre of Strategic Analysis and gathering the different actors in concern: representatives, social partners, national and European administrations, operators and industrialists, consumer associations, research organizations, etc.. The first volume is a synthesis while this second volume reprints the integral content of the five working group reports. This collective work fits inside a series of studies that the public authorities have periodically launched on the energy question. They have led to the elaboration of energy policies, still dominated by the hydrocarbon prices: ambitious and rigorous during high price eras, non-obstructive and relaxed during low price eras. Todays, the global warming dominates the energy policy. In this context, a large-scale and permanent new policy has become mandatory to reduce as quickly as possible the CO 2 emissions linked to the satisfaction of energy needs. It must definitely fit with the European framework as well. The Energy Commission recommends that France prevails upon the European Union to adopt a highly voluntaristic policy of greenhouse gases abatement at the 2050 prospects based on a fair share among the member states of the efforts to be achieved. This document includes a prospective analysis of the geopolitical situation, evaluates the technological efforts to come and lists some consistent action proposals for France and the European and national scale.

A facile-green strategy to synthesize carbon dots (CDs) with a quantum yield (QY) of nearly 13.9% has been built up, while tomato juice served as the carbon source. Interestingly, not only the precursor of CDs and the whole synthesis procedure were environmental-friendly, but this type of CDs also exhibited multiple advantages including high fluorescent QY, excellent photostability, non-toxicity and satisfactory stability. Significantly, a label-free sensitive assay for detecting carcinoembryonic antigen (CEA) in a continuous and recyclable way has been proposed on the basis of adsorption and desorption of aptamers by the surface of CDs through a competitive mechanism. To be specific, the richness of carboxyl groups of the CDs enabled strong adsorption of ssDNA to the surface of CDs through π-π stacking interactions, resulting in the effective fluorescence quenching by forming CDs-aptamer complexes. The stronger binding affinity between CEA and CEA-aptamer than the π-π stacking interactions has been taken advantage to achieve immediate recovery of the fluorescence of CDs once CEA was introduced. Thereby, quantitative evaluation of CEA concentration in a broad range from 1ngmL(-1) to 0.5ngmL(-1) with the detection limit of 0.3ngmL(-1) was realized in this way. This strategy can be applied in a recyclable way, broadening the sensing application of CDs with biocompatibility. Besides, the CDs were used for cell imaging, potentiating them towards diverse purposes. Copyright © 2016 Elsevier B.V. All rights reserved.

In order to explain why an individual or the public opinion is in favour or against the peaceful uses of nuclear energy, one should not only consider the dimension of the involved risk, as radiation protection and safety experts will often do. Many other dimensions should be considered all the more as the nuclear problem is gaining importance on a national level, becoming the topic of the day in press and other media and the subject of 'definite' position from political parties and social groups. An investigation carried out within the Protection Division of the French Atomic Energy Commission (C.E.A.) has made it possible to specify the socio-cultural dimensions at the origin of the attitudes taken on the nuclear problem in France. The nuclear topic was therefore compared with other present topics interesting public opinion; this comparison was made possible by means of an attitude survey covering various social groups. A model of social perception was thus developed [fr

A new tumour-associated antigen was recently reported by Koprowski. It can be detected in human serum by a monoclonal antibody. This antigen CA 19-9 was determined in 498 patients, and simultaneous determinations of CEA were performed in 468 patients. The patients were divided into five groups: 77 non-malignant diseases of the gastrointestinal tract, 55 gastrointestinal cancer, 174 breast cancer, 101 lung cancer, and 61 other neoplasms. We found nearly the same frequency of positive CA 19-9 and CEA specimens. In the group of gastrointestinal cancer with clinically confirmed tumour 56.5% of the serum specimens were CEA positive and 54.3% were CA 19-9 positive. No patient with chronic pancreatitis (n = 11) was CA 19-9 positive, but three were CEA positive. In female breast cancer we found 48.7% CEA positive and 15.4% CA 19-9 positive, in lung cancer 40.6% CEA positive and only 11.5% CA 19-9 positive. CA 19-9 appears to be superior to CEA with respect to the discrimination of non-malignant and malignant diseases of the pancreas. The sensitivity is not sufficient for the early diagnosis of pancreatic carcinoma. In the other gastrointestinal malignomas discordant levels of both markers were detected in 10% of the patients. This means an improvement of cancer detection. The sensitivity of CA 19-9 is apparently not sufficient for breast and lung cancer.

We have recently published some work on CEA levels in hookah (also called narghile, shisha elsewhere) and cigarette smokers. Hookah smokers had higher levels of CEA than non-smokers although mean levels were low compared to cigarette smokers. However some of them were also users of other tobacco products (cigarettes, bidis, etc.). To find serum CEA levels in ever/exclusive hookah smokers, i.e. those who smoked only hookah (no cigarettes, bidis, etc.), prepared between 1 and 4 times a day with a quantity of up to 120 g of a tobacco-molasses mixture each (i.e. the tobacco weight equivalent of up to 60 cigarettes of 1 g each) and consumed in 1 to 8 sessions. Enhanced chemiluminescent immunometric technique was applied to measure CEA levels in serum samples from 59 exclusive male smokers with age ranging from 20-80 years (mean = 58.8 +/- 14.7 years) and 8-65 years of smoking (mean = 37.7 +/- 16.8). 36 non-smokers served as controls. Subjects were divided into 3 groups according to the number of preparations; the number of sessions and the total daily smoking time: Light (1; 1; 20 min to smokers (2-4; 3-8; >2 hrs to smokers (mean: 3.58 +/- 2.61 ng/ml; n = 59) were not significantly different (p non-smokers (2.35 +/- 0.71 ng/ml). Mean levels in light, medium and heavy smokers were: 1.06 +/- 0.492 ng/ml (n = 5); 2.52 +/- 1.15 ng/ml (n = 28) and 5.11 +/- 3.08 ng/ml (n = 26) respectively. The levels in medium smokers and non-smokers were also not significantly different (p smokers, the CEA levels were significantly higher than in non-smokers (p smokers were low compared to cigarette smokers. However, heavy hookah smoking substantially raises CEA levels. Low-nitrosamines smokeless tobacco of the SNUS Swedish type could be envisaged as an alternative to smoking for this category of users and also, in a broad harm reduction perspective, to the prevalent low-quality moist snuff called naswar.

Following a first conceptual design activity in which the general design of the JT-60SA TF system was defined and frozen in agreement with all the participants in the project (CEA, ENEA, F4E), a second phase had to be launched to deal with the detailed design. In this paper, we present the work performed at CEA on the TF coil design during this second phase. Part of this work, concerns the determination of conductor hydraulic performances during operation as well as in factory. The thermohydraulic of the conductor was also assessed to confirm the need of helium inlets and a specific design was developed and qualified to be compatible with the available hydraulic performance of the cryoplant. The mechanical behavior is still to be assessed and qualified. Last but not least, the inner electrical joints of the coil have been modified with respect to the original twin-box design developed by CEA for the ITER coils in order to simplify the fabrication process. A dedicated qualification program for their manufacture is ongoing.

Carcinoembryonic antigen (CEA) is a cell surface antigen highly expressed in various cancer cell types and in healthy tissues. It has the potential to be a target for chimeric antigen receptor (CAR)-modified T-cell therapy; however, the safety of this approach in terms of on-target/off-tumor effects needs to be determined. To address this issue in a clinically relevant model, we used a mouse model in which the T cells expressing CEA-specific CAR were transferred into tumor-bearing CEA-transgenic (Tg) mice that physiologically expressed CEA as a self-antigen. The adoptive transfer in conjunction with lymphodepleting and myeloablative preconditioning mediated significant tumor regression but caused weight loss in CEA-Tg, but not in wild-type mice. The weight loss was not associated with overt inflammation in the CEA-expressing gastrointestinal tract but was associated with malnutrition, reflected in elevated systemic levels of cytokines linked to anorexia, which could be controlled by the administration of an anti-IL-6 receptor monoclonal antibody without compromising efficacy. The apparent relationship between lymphodepleting and myeloablative preconditioning, efficacy, and off-tumor toxicity of CAR-T cells would necessitate the development of CEA-specific CAR-T cells with improved signaling domains that require less stringent preconditioning for their efficacy. Taken together, these results suggest that CEA-specific CAR-based adoptive T-cell therapy may be effective for patients with CEA + solid tumors. Distinguishing the fine line between therapeutic efficacy and off-tumor toxicity would involve further modifications of CAR-T cells and preconditioning regimens.

Full Text Available Aim: To evaluate the efficacy of 18flurodeoxyglucose positron emission tomography/computer tomography (18F-FDG PET/CT in investigating patients with elevated carcinoembryonic antigen (CEA and without known primary malignancy, and the impact of PET/CT findings on patient management. Setting and Design: PET/CT scans done in a tertiary hospital between December 2007 and February 2012 for elevated CEA in patients without known primary malignancy were retrospectively reviewed. Materials and Methods: The PET/CT findings, patients' clinical information, level of CEA, histological diagnosis, and subsequent management were retrieved by the electronic patient record for analysis. Statistical Analysis: Data were analyzed using SPSS version 19. Results: One hundred and one PET/CT scans were performed for patients with elevated CEA. Fifty-eight of these were performed for patients with known primary malignancy and were excluded; 43 PET/CT scans were performed for patients without known primary malignancy and were included. Thirty-three (77% had a positive PET/CT. Among the 32 patients with malignancy, 15 (47% suffered from lung cancer and 8 (25% suffered from colorectal cancer. The sensitivity (97%, specificity (82%, positive predictive value (94%, negative predictive value (90%, and accuracy (93% were calculated. Thirty (91% patients had resultant change in management. The mean CEA level for patients with malignancy (46.1 ng/ml was significantly higher than those without malignancy (3.82 ng/ml (P < 0.05. In predicting the presence of malignancy, a CEA cutoff at 7.55 ng/ml will achieve a sensitivity of 91% and a specificity of 73%. Conclusion: PET/CT, in our study population, appears to be sensitive, specific, and accurate in investigating patients with elevated CEA and without known primary malignancy. In addition to diagnosis of underlying primary malignancy, PET/CT also reveals occult metastases which would affect patient treatment options.Its role in

The project's objectives are the evaluation of the reliability concerning the identification of Human Factors as contributing factors by a computer supported event analysis (CEA). CEA is a computer version of SOL (Safety through Organizational Learning). Parts of the first step were interviews with experts from the nuclear power industry and the evaluation of existing computer supported event analysis methods. This information was combined to a requirement profile for the CEA software. The next step contained the implementation of the software in an iterative process of evaluation. The completion of this project was the testing of the CEA software. As a result the testing demonstrated that it is possible to identify contributing factors with CEA validly. In addition, CEA received a very positive feedback from the experts. (orig.) [de
