The Nuclear Production Division of EDF is comprised of 19 power stations (58 PWR reactors) and 2 national engineering organisations. Nuclear Inspection (IN) is an internal assessment unit of the EDF Nuclear Production Directorate. At the request of the Directorate, it carries out periodic evaluations of all the units of the division. The evaluation of the nuclear sites (EGE: Overall Excellence Assessment) is carried out every 4 years, an intermediate evaluation is also carried out between each EGE. These evaluations are independent of the WANO and IAEA evaluations. Exchanges are carried out between Nuclear Inspection and the other international operators (for example, USA (INPO), England, China...) to share site evaluation methods. These evaluations are carried out by a team of 30 inspectors, reinforced during each evaluation by 10 peers who come from the various French nuclear sites. Nuclear Inspection produces a performance standards document for each FUNCTIONAL AREA, which is based on the requirements of the company. On the whole, 13 areas are evaluated during each inspection, in particular: Management, Operations, Maintenance, Engineering and Chemistry. The area of reactor plant chemistry has been evaluated since 2009. The Chemistry performance standards document is written from the EDF internal requirements and international references. During site evaluations, all the performance standards are assessed for compliance. The Chemistry performance standards document is comprised of 3 topics: Management of plant chemistry, The respect of the chemical and radiochemical specifications, The condition of the laboratories and the sampling lines, measuring equipment, and chemical products. The evaluations carried out make it possible to define strengths and weaknesses which the sites must address. After each evaluation, the assessment is presented to the site management and to the director of EDF Nuclear Production. For 4 years these evaluations have allowed progress to

The ACS Division of Nuclear Chemistry and Technology was initiated in 1955 as a subdivision of the Division of Industrial and Engineering Chemistry. Probationary divisional status was lifted in 1965. The Division’s first symposium was held in Denver in 1964 and it is fitting that we kicked-off the 50th Anniversary in Denver in the spring of 2015. Listed as a small ACS Division with only about 1,000 members, NUCL’s impact over the past fifty years has been remarkable. National ACS meetings have had many symposia sponsored or cosponsored by NUCL that included Nobel Laureates, U.S. Senators, other high-ranking officials and many students as speakers. The range of subjects has been exceptional as are the various prestigious awards established by the Division. Of major impact has been the past 30 years of the NUCL Nuclear Chemistry Summer Schools to help fill the void of qualified nuclear scientists and technicians. In celebrating the 50th Anniversary we honor the past, celebrate the present and shape the future of the Division and nuclear science and technology. To celebrate this auspicious occasion a commemorative lapel pin has been designed for distribution to NUCL Division members.

Quantitative x-ray diffraction analyses of samples used for sorption studies by the Isotope and Nuclear Chemistry Division, Los Alamos National Laboratory

Chipera, S.J.; Bish, D.L.

1989-09-01

Yucca Mountain, Nevada, is currently being investigated to determine its suitability to host our nation's first geologic high-level nuclear waste repository. As part of an effort to determine how radionuclides will interact with rocks at Yucca Mountain, the Isotope and Nuclear Chemistry (INC) Division of Los Alamos National Laboratory has conducted numerous batch sorption experiments using core samples from Yucca Mountain. In order to understand better the interaction between the rocks and radionuclides, we have analyzed the samples used by INC with quantitative x-ray diffraction methods. Our analytical methods accurately determine the presence or absence of major phases, but we have not identified phases present below ∼1 wt %. These results should aid in understanding and predicting the potential interactions between radionuclides and the rocks at Yucca Mountain, although the mineralogic complexity of the samples and the lack of information on trace phases suggest that pure mineral studies may be necessary for a more complete understanding. 12 refs., 1 fig., 1 tab

Nuclear size and cell division delay

International Nuclear Information System (INIS)

Bird, R.P.

1986-01-01

Radiation-induced division delay has been linked to damage at the nuclear envelope. Further, cells in G 2 phase are drastically arrested by high LET radiation such that single particles traversing cell nuclei may produce measurable division delay. A modest effort was initiated using two related cell lines of different size, near-diploid cells and near-tetraploid cells of Chinese hamster origin, to compare their sensitivity for radiation-induced division delay. If the nuclear surface is the critical target, then a larger nuclear cross-section presented to an alpha-particle beam should exhibit delay induced by a lesser particle fluence. Preliminary estimates of the extent of delay in asynchronous cultures following low doses of gamma-irradiation or of alpha-irradiation were made by in-situ observation of the time of onset of mitosis and by fixation and staining of cultures to determine the mitotic index as a function of time after irradiation. The basic approach to evaluating division delay will be to use Colecemid to accumulate mitotic cells over a period of time

Chemistry in and from nuclear fusion

Okamoto, M.

The time, of the realization of nuclear fusion reactor is not clear even now. However, it is generally believed that the nuclear fusion is only one candidate of the big power source for humanbeing. We may be not able to, but our children or grandchildren would be able to see the nuclear fusion reactors. The nuclear fusion development may be the last and biggest technology program for us, so it will take so long leading time. Now, we are in the first stage of this leading time, I think. As being found in the history of every technology, chemistry is essential to develop the fusion nuclear technology. To assure the safety of the nuclear fusion system, chemistry should play the main role. There have been already not a few advanced chemistry initiated by the connected technologies with the nuclear fusion researches. The nuclear fusion needs chemistry and the nuclear fusion leads some of the new phases of chemistry. (author)

Lieser, K.H.

1980-01-01

The study in this book begins with the periodic system of elements (chapter 1). The physical fundamentals necessary to understand nuclear chemistry are dealt with in chapter 2. Chapter 3 and 4 treat the influence of the mass number on the chemical behaviour (isotope effect) and the isotope separation methods thus based on this effect. A main topic is studied in chapter 5, the laws of radioactive decay, a second main topic is dealt with in chapter 8, nuclear reactions. The chemical effects of nuclear reactions are treated on their own chapter 9. Radiochemical reactions which are partly closely linked to the latter are only briefly discussed in chapter 10. The following chapters discuss the various application fields of nuclear chemistry. The large apparatus indispensable for nuclear chemistry is dealt with in a special chapter (chapter 12). Chapter 15 summarizes the manifold applications. (orig.) [de

Chemistry management system for nuclear power plants

Nagasawa, Katsumi; Maeda, Katsuji

1998-01-01

Recently, the chemistry management in the nuclear power plants has been changing from the problem solution to the predictive diagnosis and maintenance. It is important to maintain the integrity of plant operation by an adequate chemistry control. For these reasons, many plant operation data and chemistry analysis data should be collected and treated effectively to evaluate chemistry condition of the nuclear power plants. When some indications of chemistry anomalies occur, quick and effective root cause evaluation and countermeasures should be required. The chemistry management system has been developed as to provide sophisticate chemistry management in the nuclear power plants. This paper introduces the concept and functions of the chemistry management system for the nuclear power plants. (author)

An ideal teaching program of nuclear chemistry in the undergraduate chemistry curriculum

International Nuclear Information System (INIS)

Uenak, T.

2009-01-01

It is well known that several reports on the common educational problems of nuclear chemistry have been prepared by certain groups of experts from time to time. According to very important statements in these reports, nuclear chemistry and related courses generally do not take sufficient importance in undergraduate chemistry curricula and it was generally proposed that nuclear chemistry and related courses should be introduced into undergraduate chemistry curricula at universities worldwide. Starting from these statements, an ideal program in an undergraduate chemistry curriculum was proposed to be introduced into the undergraduate chemistry program at the Department of Chemistry, Ege University, in Izmir, Turkey during the regular updating of the chemistry curriculum. Thus, it has been believed that this Department of Chemistry has recently gained an ideal teaching program in the field of nuclear chemistry and its applications in scientific, industrial, and medical sectors. In this contribution, the details of this program will be discussed. (author)

Water chemistry technology. One of the key technologies for safe and reliable nuclear power plant operation

International Nuclear Information System (INIS)

Uchida, Shunsuke; Katsumura, Yosuke

2013-01-01

Water chemistry control is one of the key technologies to establish safe and reliable operation of nuclear power plants. Continuous and collaborative efforts of plant manufacturers and plant operator utilities have been focused on optimal water chemistry control, for which, a trio of requirements for water chemistry should be simultaneously satisfied: (1) better reliability of reactor structures and fuel rods; (2) lower occupational exposure and (3) fewer radwaste sources. Various groups in academia have carried out basic research to support the technical bases of water chemistry in plants. The Research Committee on Water Chemistry of the Atomic Energy Society of Japan (AESJ), which has now been reorganized as the Division of Water Chemistry (DWC) of AESJ, has played important roles to promote improvements in water chemistry control, to share knowledge about and experiences with water chemistry control among plant operators and manufacturers and to establish common technological bases for plant water chemistry and then to transfer them to the next generation of plant workers engaged in water chemistry. Furthermore, the DWC has tried and succeeded arranging R and D proposals for further improvement in water chemistry control through roadmap planning. In the paper, major achievements in plant technologies and in basic research studies of water chemistry in Japan are reviewed. The contributions of the DWC to the long-term safe management of the damaged reactors at the Fukushima Daiichi Nuclear Power Plant until their decommissioning are introduced. (author)

The Nuclear and Radiochemistry in Chemistry Education Curriculum Project

International Nuclear Information System (INIS)

Robertson, J.D.; Missouri University, Columbia, MO; Kleppinger, E.W.

2005-01-01

Given the mismatch between supply of and demand for nuclear scientists, education in nuclear and radiochemistry has become a serious concern. The Nuclear and Radiochemistry in Chemistry Education (NRIChEd) Curriculum Project was undertaken to reintroduce the topics normally covered in a one-semester radiochemistry course into the traditional courses of a four-year chemistry major: general chemistry, organic chemistry, quantitative and instrumental analysis, and physical chemistry. NRIChEd uses a three-pronged approach that incorporates radiochemistry topics when related topics in the basic courses are covered, presents special topics of general interest as a vehicle for teaching nuclear and radiochemistry alongside traditional chemistry, and incorporates the use of non-licensed amounts of radioactive substances in demonstrations and student laboratory experiments. This approach seeks not only to reestablish nuclear science in the chemistry curriculum, but to use it as a tool for elucidating fundamental and applied aspects of chemistry as well. Moreover, because of its relevance in many academic areas, nuclear science enriches the chemistry curriculum by encouraging interdisciplinary thinking and problem solving. (author)

Research in nuclear chemistry has seen a huge growth over the last few decades. The large umbrella of nuclear chemistry includes several research areas such as nuclear fission, reactions, spectroscopy, nuclear probes and nuclear analytical techniques. Currently, nuclear chemistry research has extended its horizon into various applications like nuclear medicine, isotopes for understanding physico chemical processes, and addressing environmental and biomedical problems. Tremendous efforts are going on for synthesizing new elements (isotopes), isolating physically or chemically wherever possible and investigating their properties. Theses studies are useful to understand nuclear and chemical properties at extreme ends of instability. In addition, nuclear chemists are making substantial contribution to astrophysics and other related areas. During this talk, a few of the contributions made by nuclear chemistry group of BARC will be discussed and possible future areas of research will be enumerated. (author)

Nuclear chemistry research for the safe disposal of nuclear waste

International Nuclear Information System (INIS)

Fanghaenel, Thomas

2011-01-01

The safe disposal of high-level nuclear waste and spent nuclear fuel is of key importance for the future sustainable development of nuclear energy. Concepts foresee the isolation of the nuclear waste in deep geological formations. The long-term radiotoxicity of nuclear waste is dominated by plutonium and the minor actinides. Hence it is essential for the performance assessment of a nuclear waste disposal to understand the chemical behaviour of actinides in a repository system. The aqueous chemistry and thermodynamics of actinides is rather complex in particular due to their very rich redox chemistry. Recent results of our detailed study of the Plutonium and Neptunium redox - and complexation behaviour are presented and discussed. (author)

Position paper on main areas of nuclear chemistry research and application

International Nuclear Information System (INIS)

2001-01-01

Nuclear chemistry, with its specialized areas of nuclear chemistry, radiochemistry, and radiation chemistry, mainly covers these fields: basic research in nuclear chemistry; actinide chemistry; radioanalysis; nuclear chemistry in the life sciences, geosciences, and cosmic chemistry; radiotracers in technology; nuclear power technology; nuclear waste management; tritium chemistry in fusion technology, and radiation protection and radioecology. In the more than one hundred years of history of this branch of science and technology, which was opened up by the discovery of radioactivity and of the radioelements, pioneering discoveries and developments have been made in many sectors. Far beyond the confines of this area of work, they have achieved overriding importance in applications in many fields of technology and industry and in the life sciences. Research and application in nuclear chemistry continue to be highly relevant to society, ecology, and the economy, and the potential of science and technology in this field in Germany is acknowledged internationally. In the light of this vast area of activity, and against the need to maintain competence in nuclear chemistry for the use of nuclear power, irrespective of the status of this continued use in Germany, nuclear chemistry is indispensable to the solution of future problems. The Nuclear Chemistry Group of the Gesellschaft Deutscher Chemiker therefore uses this position paper to draw attention to the urgent need to keep up and further advance nuclear chemistry applications in a variety of areas of science and technology, also as a public duty of thorough education and research.

2011-01-01

Chemistry - radiochemistry, radiation chemistry and nuclear chemical engineering play a very important role in the nuclear power development. Even at present, the offered technology is well developed, but still several improvements are needed and proposed. These developments concern all stages of the technology; front end, reactor operation (coolant chemistry and installation components decontamination, noble gas release control), back end of fuel cycle, etc. Chemistry for a partitioning and a transmutation is a new challenge for the chemists and chemical engineers. The IV th generation of nuclear reactors cannot be developed without chemical solutions for fuel fabrication, radiation-coolants interaction phenomena understanding and spent fuel/waste treatment technologies elaboration. Radiochemical analytical methods are fundamental for radioecological monitoring of radioisotopes of natural and anthropological origin. This paper addresses just a few subjects and is not a detailed overview of the field, however it illustrates a role of chemistry for a safe and economical nuclear power development. (author)

Nuclear chemistry counting facilities: requirements definition

O'Brien, D.W.; Baker, J.

1979-01-01

In an effort to upgrade outdated instrumentation and to take advantage of current and imminent technologies the Nuclear Chemistry Division at Lawrence Livermore Laboratory is about to undertake a major upgrade of their low level radiation counting and analysis facilities. It is expected that such a project will make a more coordinated data acquisition and data processing system, reduce manual data handling operations and speed up data processing throughput. Before taking on a systems design it is appropriate to establish a definition of the requirements of the facilities. This report examines why such a project is necessary in the context of the current and projected operations, needs, problems, risks and costs. The authors also address a functional specification as a prelude to a system design and the design constraints implicit in the systems implementation. Technical, operational and economic assessments establish necessary boundary conditions for this discussion. This report also establishes the environment in which the requirements definition may be considered valid. The validity of these analyses is contingent on known and projected technical, scientific and political conditions

This report describes the work carried by Radiochemistry Division of BARC during the period 1997 and 1998. The work is divided in three main branches (1) Nuclear Chemistry (2) Actinides Chemistry (3) Actinide Spectroscopy. During this period research in nuclear chemistry was focussed on nuclear fission, nuclear reactions, neutron activation analysis, use of nuclear techniques for understanding of physico-chemical phenomena and developmental activities in non-destructive assay techniques. The research work on chemistry of actinides was directed on basic as well as applied studies related to complexation and extraction behaviour of actinides and lanthanides with a variety of novel ligands. The choice of complexing ligands was made with a view to examining the suitability in reprocessing streams, treatment of high level active waste and recovery of valuables. The third part spectroscopy of actinides describes the basic studies solid state spectroscopy of actinides and analytical spectroscopy for trace metallic assay. The solid state spectroscopy investigations were carried out using EPR, ENDOR, fluorescence, thermally stimulated luminescence and photo acoustic for spectroscopy techniques. In the analytical spectroscopy work a lot of stress was given on finding suitable chemical separation procedures for pre concentration of trace metals and a determination by ICP-AES/ETA-AAS techniques.

Seaborg, G.I.

Otto Hahn's book, Applied Radiochemistry, published in 1936, marked the author's entry into this field. Notes concerning a lecture course, An Introduction to Nuclear Chemistry, given during the summer of 1942 at the University of Chicago, as an introduction to the Plutonium Project of the Manhattan District, were widely distributed for use by participants in the Project. Nuclear chemistry courses, undergraduate and graduate, instigated at Berkeley in 1946, were taken by large numbers of students many of who became pioneers in the field. Noteworthy is Friedlander's and Kennedy's 1949 textbook, Introduction to Radiochemistry (and subsequent revisions). These courses and this book serve as typical examples, many other such courses were taught and books published during the intervening years. More recently the Department of Energy Summer School in Nuclear Chemistry (for high school students) at San Jose State University has helped to revive student interest in nuclear chemistry

The need for engineers and scientists who can ensure safe and secure use of nuclear energy is large in Sweden and internationally. Chalmers University of Technology is therefore launching a new 2-year master's program in Nuclear Engineering, with start from the autumn of 2009. The program is open to Swedish and foreign students. The program starts with compulsory courses dealing with the basics of nuclear chemistry and physics, radiation protection, nuclear power and reactors, nuclear fuel supply, nuclear waste management and nuclear safety and security. There are also compulsory courses in nuclear industry applications and sustainable energy futures. The subsequent elective courses can be chosen freely but there is also a possibility to choose informal tracks that concentrate on nuclear chemistry or reactor technology and physics. The nuclear chemistry track comprises courses in e.g. chemistry of lanthanides, actinides and transactinides, solvent extraction, radioecology and radioanalytical chemistry and radiopharmaceuticals. The program is finished with a one semester thesis project. This is probably a unique master program in the sense of its combination of deep courses in both nuclear technology and nuclear chemistry.

The Chemical Technology Division (CMT) is one of eight engineering research divisions within Argonne National Laboratory (ANL), one of the U.S. government's oldest and largest research laboratories. The University of Chicago oversees the laboratory on behalf of the U.S. Department of Energy (DOE). Argonne's mission is to conduct basic scientific research, to operate national scientific facilities, to enhance the nation's energy resources, and to develop better ways to manage environmental problems. Argonne has the further responsibility of strengthening the nation's technology base through developing industrial technology and transferring that technology to industry. The Chemical Technology Division is a diverse early-stage engineering organization, specializing in the treatment of spent nuclear fuel, development of advanced power sources, and management of both high- and low-level nuclear wastes. Although this work is often indistinguishable from basic research, our efforts are directed toward the practical devices and processes that are covered by ANL's mission. Additionally, the Division operates the Analytical Chemistry Laboratory, which provides a broad range of analytical services to ANL and other organizations. The Division is multi-disciplinary. Its people have formal training as ceramists; physicists; material scientists; electrical, mechanical, chemical, and nuclear engineers; and chemists. They have experience working in academia, urban planning, and the petroleum, aluminum, and automotive industries. Their skills include catalysis, ceramics, electrochemistry, metallurgy, nuclear magnetic resonance spectroscopy, and petroleum refining, as well as the development of nuclear waste forms, batteries, and high-temperature superconductors. In this annual report we present an overview of the technical programs together with representative highlights.

Nuclear chemistry and Radiochemistry in the USA

International Nuclear Information System (INIS)

Kronenberg, A.

2004-01-01

Nuclear chemistry and radiochemistry are very young sciences which developed at an extremely brisk pace within a very short period of time after the discovery of nuclear fission in 1938, and caused profound societal changes. In the United States, nuclear chemistry developed very differently from Germany, where nuclear research initially had been banned after the Second World War. The prime mover in the development in the United States was the Manhattan Project, the construction of the atomic bomb. The counteract the impending shortage of qualified personnel, important institutions have begun to establish training and support programs in the field. The National Laboratories in the United States introduced a National Security Internship Program, while the U.S. Department of Energy (DOE) tries to promote cooperation, and thus the training of personnel, by launching programs of its own. Yet, a greater shortage of qualified personnel is becoming apparent. The situation of nuclear chemistry and radiochemistry in the United States can be summarized in the finding that research at the National Laboratories is very wide ranging. It receives sufficient funds from the DOE. However, the National Laboratories show a very high proportion of elderly personnel, a problem which will have to be corrected in the years to come. This may be helped by the Summer Schools financed by the DOE, though a summer school of six weeks cannot replace a sound training in nuclear chemistry of the kind still to be found in Germany.

Bioorganic chemistry plays a pivotal role of co-ordination amongst the research and developmental activities of physical, biological, material and nuclear sciences. Understandably, the domain of bioorganic chemistry encompasses overlapping scientific fields, and often involves multi-disciplinary subjects. The research activities of bioorganic research at BARC are, therefore directed with reference to deliverables, relevant to various nuclear and non-nuclear programmes of the department. Also, the activities of the division are fine tuned to address the contemporary needs. It is now well recognized that organic compounds are essential in various programmes of nuclear technology. These include solvents and membranes for the back-end process, carrier molecules for radiopharmaceuticals, optoelectrical materials and sensors for high tech applications etc. Coupled with this, bioorganics also form integral part of the departmental mission-oriented societal programmes in the areas of health and agriculture

Fission yeast cells undergo nuclear division in the absence of spindle microtubules.

Directory of Open Access Journals (Sweden)

Stefania Castagnetti

2010-10-01

Full Text Available Mitosis in eukaryotic cells employs spindle microtubules to drive accurate chromosome segregation at cell division. Cells lacking spindle microtubules arrest in mitosis due to a spindle checkpoint that delays mitotic progression until all chromosomes have achieved stable bipolar attachment to spindle microtubules. In fission yeast, mitosis occurs within an intact nuclear membrane with the mitotic spindle elongating between the spindle pole bodies. We show here that in fission yeast interference with mitotic spindle formation delays mitosis only briefly and cells proceed to an unusual nuclear division process we term nuclear fission, during which cells perform some chromosome segregation and efficiently enter S-phase of the next cell cycle. Nuclear fission is blocked if spindle pole body maturation or sister chromatid separation cannot take place or if actin polymerization is inhibited. We suggest that this process exhibits vestiges of a primitive nuclear division process independent of spindle microtubules, possibly reflecting an evolutionary intermediate state between bacterial and Archeal chromosome segregation where the nucleoid divides without a spindle and a microtubule spindle-based eukaryotic mitosis.

Advances in nuclear chemistry and its applications in the Philippines

International Nuclear Information System (INIS)

Dela Rosa, Alumanda M.

2015-01-01

Nuclear chemistry was born almost 120 years ago with the discovery of radioactivity by Antoine Henry Becquerel in 1896. Nuclear chemistry is a subfield of chemistry that deals with radioactivity, nuclear reactions and processes, and nuclear properties. The composition of the nucleus and the changes that occur within the nucleus define the properties of the radioisotope and the nuclear reactions and processes it is involved in. Almost six decades ago, nuclear chemistry established its roots in the Philippines under the Philippine Atomic Energy Commission, presently the Philippine Nuclear Research Institute. The main areas of nuclear chemistry, namely, namely radiochemistry, radiation chemistry, radiation biology, and isotopic chemistry have been studies, and have found applications in food and agriculture, medicine and health, in idustry, and in the protection of the environment. Early work in nuclear chemistry utilized the Philippine Research Reactor (PRR-1) for the production of radioisotopes which were used in either research or direct applications in food and agriculture, health and medicine, and industry. The PRR-1 provided neutrons for the non destructive multi element analysis of various samples using the neutron activation analysis technique. Radioactive materials as sources of ionizing radiation are being used extensively to study the chemical and biological effects of radiation on matter. Current studies involve the irradiation of certain plants and insects causing changes in their DNA which result in mutation for better crop varieties and sterility in insects for quarantine treatment and pest management. Radiation can modify the properties of polymers. Natural polymers such as carrageenan, chitosan and cellulose in abaca and water hyacinth fibers are subjected to gamma irradiation changing their properties and resulting in new products such as wound drressing, hemostatic agents, plant growth promoters, and metal-chelating agents. Radioisotopes are also

International Nuclear Information System (INIS)

1981-08-01

The work of the Division in the areas of solid state science, radiation, physical and analytical chemistry, and materials science during the quarter is described. Measurements of ion stopping power have emphasized the importance of axial symmetry and may be used to show the contribution of nuclear inelastic events to stopping processes. Enhancement of ion scattering at 180 degrees can occur even in the first few layers of a single crystal of gold implanted with heavy atoms. Agreement has been obtained between experimental and calculated rates for dechanneling of protons in gold. The rate of decomposition of HOI in aqueous solutions has been determined. The effects of radiation on dithiothreitol is being studied. Laser photochemistry work includes investigations of multiphoton dissociation and of laser-induced zirconium isotope separation. A method has been found for the preparation of oxygen gas samples for the determination of oxygen isotope ratios in water, and high-performance liquid chromatography has been applied to metals in ground water. Sputtered coatings of stainless steel on the surface of zircaloy fuel cladding reduce the oxidation rate in steam. A theoretically-based design equation for irradiation growth of pressure tubes has been developed. Studies on the effect of small strains on zircaloy-2 tubing show the need to avoid even small amounts of compressive deformation of calandria tubes

Developments in nuclear power plant water chemistry

Fruzetti, K.; Wood, C.J.

2007-01-01

This paper illustrates the changing role of water chemistry in current operation of nuclear power plants. Water chemistry was sometimes perceived as the cause of materials problems, such as denting in PWR steam generators and intergranular stress corrosion cracking in BWRs. However, starting in the last decade, new chemistry options have been introduced to mitigate stress corrosion cracking and reduce fuel performance concerns. In BWRs and PWRs alike, water chemistry has evolved to successfully mitigate many problems as they have developed. The increasing complexity of the chemistry alternatives, coupled with the pressures to increase output and reduce costs, have demonstrated the need for new approaches to managing plant chemistry, which are addressed in the final part of this paper.

Chemistry control in a boiling water reactor (BWR) plant has a close relationship with radiation field buildup, fuel reliability, integrity of plant components and materials, performance of the water treatment systems and radioactive waste generation. Chemistry management in BWR plants has become more important in order to maintain and enhance plant reliability. Adequate chemistry control and management are also essential to establish, maintain, and enhance plant availability. For these reasons, we have developed the advanced chemistry management system for nuclear power plants in order to effectively collect and evaluate a large number of plant operating and chemistry data.

1997-01-01

The separation of actinide elements from various waste materials, either produced in nuclear fuel cycle or in the past during nuclear weapon production, represent a significant issue facing developed countries. Improvements in the efficiencies of the separation processes can be expected from a better knowledge of the chemistry of these elements in these complex matrices. The Nuclear Science Committee of the OECD/NEA has established a task force of experts in actinide chemistry to review the current and developing separation techniques and chemical processes. Recommendations were made for future research and development programs. This article presents briefly the work of the Task Force which will be published soon as an OECD/NEA/NSC Report. (author)

The Summer Schools are intensive, six-week program involving both a lecture component covering fundamental principles of nuclear chemistry and radiochemistry and a laboratory component allowing hands-on experience for the students to test many of the basic principles they learn about in lecture. Each site hosted 12 undergraduate students annually, and students received coursework credits towards their undergraduate degrees. Up to 7 student credit hours were earned at San Jose State University, and Brookhaven students received up to 6 college credits through BNL's management partner, SUNY Stony Brook. Funding from the award period covered travel, housing, educational expenses, and student stipends, for the 24 undergraduate participants. Furthermore, funding was also used to cover expenses for lecturers and staff to run the programs at the two facilities. The students were provided with nuclear and radiochemistry training equivalent to a three-hour upper-level undergraduate course along with a two-hour hands-on laboratory experience within the six-week summer period. Lectures were held 5 days per week. Students completed an extensive laboratory sequence, as well as radiation safety training at the start of the Summer Schools. The summer school curriculum was enhanced with a Guest Lecture series, as well as through several one-day symposia and organized field trips to nuclear-related research and applied science laboratories. This enrichment afforded an opportunity for students to see the broader impacts of nuclear science in today's world, and to experience some of the future challenges through formal and informal discussions with

Department of Nuclear Physical Chemistry - Overview

Full text: Research in the Department of Nuclear Physical Chemistry concentrates on three main topics: 1. Radiochemistry of transactinide elements; 2. Environmental radioactivity and related problems; 3. Preparation and applications of radioactive isotopes. The investigations on radiochemistry of transactinide elements are carried out in the Laboratory of Chemistry and Radiochemistry. Practical difficulties due to short half-lives and very low cross sections of formation of the superheavy nuclei are being overcome by developing fast and efficient methods of chemical separation, basing mostly on ion-exchange processes which are thoroughly studied via model experiments on lighter homologues of the elements of interest. During the year 2001, work with composite ferrocyanide sorbents was continued, and the efforts resulted in a patent application. The developed ion-exchangers (whose characteristics are constantly checked and improved in the laboratory) can find practical applications in environmental protection as well as in fundamental studies on the most exotic elements: 104 Rf, 105 Db, 106 Sg, 107 Bh, 108 Hs, and more. As to the latter, the discovery in Dubna of the relatively long-lived element 114 (t 1/2 =30s) gives hope that studies on aqueous chemistry of the elements Z =107 would be feasible. In this context, chemical methods of separation and identification of the heaviest elements are necessary to know the behaviour of the whole decay chains, for example: 114 -α-112 -α-110 -α-108 -α-106. The group is contributing its expertise to the top specialist international co-operation, involving the Joint Institute of Nuclear Research, Dubna, Russia, the Institute of Geochemistry and Analytical Chemistry of the Russian Academy of Sciences, Moscow, Russia, and three German institutions: the Technical University of Dresden, the University of Mainz, and the GSI Darmstadt. The Environmental Radioactivity Laboratory is following up traces of α, β, and γ radioactive

Meyer, R.A.

1979-01-01

Rapid Automated Nuclear Chemistry (RANC) can be thought of as the Z-separation of Neutron-rich Isotopes by Automated Methods. The range of RANC studies of fission and its products is large. In a sense, the studies can be categorized into various energy ranges from the highest where the fission process and particle emission are considered, to low energies where nuclear dynamics are being explored. This paper presents a table which gives examples of current research using RANC on fission and fission products. The remainder of this text is divided into three parts. The first contains a discussion of the chemical methods available for the fission product elements, the second describes the major techniques, and in the last section, examples of recent results are discussed as illustrations of the use of RANC

Fission product chemistry in severe nuclear reactor accidents

International Nuclear Information System (INIS)

Nichols, A.L.

1990-09-01

A specialist's meeting was held at JRC-Ispra from 15 to 17 January 1990 to review the current understanding of fission-product chemistry during severe accidents in light water reactors. Discussions focussed on the important chemical phenomena that could occur across the wide range of conditions of a damaged nuclear plant. Recommendations for future chemistry work were made covering the following areas: (a) fuel degradation and fission-product release, (b) transport and attenuation processes in the reactor coolant system, (c) containment chemistry (iodine behaviour and core-concrete interactions)

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)

Servian, J.L.

1984-01-01

The application of chemical principles and techniques have played a major role in the development of nuclear sciences and technology. The discovery of radioactivity, the isolation of radium and polonium, the discovery of artificial radioactivity and nuclear fission and the production of transuranium elements are historical landmarks that show the prominent role performed by chemistry. The purpose of this paper is to summarize the chemistry areas and experimental facilities for programmes of training, research and development, and service that might be designed for implementation at the Centre when appropriate. Though the areas are separately presented for analysis, they are closely related among themselves and also related to other activities of the Centre. (author)

Handbook on process and chemistry of nuclear fuel reprocessing version 2

International Nuclear Information System (INIS)

2008-10-01

Aqueous nuclear fuel reprocessing technology, based on PUREX technology, has wide applicability as the principal reprocessing technology of the first generation, and relating technologies, waste management for example, are highly developed, too. It is quite important to establish a database summarizing fundamental information about the process and the chemistry of aqueous reprocessing, because it contributes to establish and develop fuel reprocessing technology and nuclear fuel cycle treating high burn-up UO 2 fuel and spent MOX fuel, and to utilize aqueous reprocessing technology much widely. This handbook is the second edition of the first report, which summarizes the fundamental data on process and chemistry, which was collected and examined by 'Editing Committee of Handbook on Process and Chemistry of Nuclear Fuel Reprocessing' from FY 1993 until FY 2000.

Nagame, Y.; Haba, H.; Tsukada, K.

2002-01-01

Nuclear chemistry study of trans actinide elements in Japan is currently being in progress at JAERI (Japan Atomic Energy Research Institute). We have developed new experimental apparatuses: a beam-line safety system for the usage of the gas-jet coupled radioactive 248 Cm target chamber, a rotating wheel catcher apparatus for the measurement of α and spontaneous fission decay of the transactinides, MANON (Measurement system for Alpha particles and spontaneous fission events ON line), and an automated rapid chemical separation apparatus based on the high performance liquid chromatography, AIDA (Automated Ion exchange separation system coupled with the Detection apparatus for Alpha spectroscopy). The transactinide nuclei, 261 Rf and 262 Db, have been successfully produced via the reactions of 248 Cm( 18 O,5n) and 248 Cm( 19 F,5n), respectively, and the excitation functions for each reaction have been measured to evaluate the optimum irradiation condition for the production of these nuclei. The maximum cross sections in each reaction were 13 nb at the 18 O beam energy of 94-MeV and 1.5 Nb at the 103-MeV 19 F beam energy. On-line ion exchange experiments of Rf together with the lighter homologues Zr and Hf in the HCl, HNO 3 and HF solutions with AIDA have been carried out, and the results clearly show that the behavior of Rf is typical of the group-4 element. Relativistic molecular orbital calculations of the chloride and nitrate complexes of tetravalent Rf are also being performed to gain an understanding of the complex chemistry. Prospects and some recent experimental results for the nuclear chemistry study of the transactinide elements at JAERI are discussed. (author)

Kameswaran; Ram

2012-09-01

Chemistry program is one of the essential programs for the safe operation of a nuclear power plant. It helps to ensure the necessary integrity, reliability and availability of plant structures, systems and components important to safety. Additionally, the program plays an important role in asset preservation, limiting radiation exposure and environmental protection. A good chemistry program will minimize corrosion of materials, reduce activation products, minimize of the buildup of radioactive material leading to occupational radiation exposure and it helps limit the release of chemicals and radioactive materials to the environment. The legal basis for the chemistry oversight at Canadian NPPs is established by the Nuclear Safety and Control Act and its associated regulations. It draws on the Canadian Nuclear Safety Commission's regulatory framework and NPP operating license conditions that include applicable standards such as CAN/CSA N286-05 Management System Requirements for Nuclear Power Plants. This paper focuses on the regulatory oversight strategy used in Canada to assess the performance of chemistry program at the nuclear power plants (NPPs) licensed by CNSC. The strategy consists of a combination of inspection and performance monitoring activities. The activities are further supported from information gathered through staff inspections of cross-cutting areas such as maintenance, corrective-action follow-ups, event reviews and safety related performance indicators.

Robertson, J.D.; Kleppinger, E.W.

1994-01-01

Although many areas of major national need depend critically on professionals trained in nuclear and radiochemistry, there has been a steady decline in both the educational opportunities and student interest in this area. One major factor that has contributed greatly to the lack of student interest in nuclear and radiochemistry is that most undergraduate students in chemistry and other sciences are no longer introduced to these topics. This deficiency in the traditional chemistry curriculum, coupled with the negative public perception towards all things open-quotes nuclear,close quotes has resulted in a serious shortage of individuals with a background in this area. The authors are trying to address this problem by open-quotes educating the educators.close quotes The authors are developing a set of summer workshops to provide faculty from four-year colleges with the curriculum materials, training, and motivation to incorporate these topics on a continuing basis in their traditional undergraduate chemistry curricula. The first series of workshops is scheduled for the summer of 1995

In the review the history of research two-nuclear neurons is stated and two hypotheses about mechanisms of their formation are analysed: by sincitial fusion or amytotic divisions. The facts of discrepancy of the former orthodox cellular theory categorically denying possibility sincitial of communications in nervous system and of sincitial fusion neurons are mentioned. As an example results of ultrastructural researches of occurrence sincitium in a cortex of the big brain of rats, in autonomic ganglions, in hypocampus and a cerebellum of adult animals are presented. The video data of the sincitial fusion of live neurons and the mechanism of formation multinuclear neurons in tissue culture are analyzed. Existing data about amytotic a way of formation two-nuclear neurons are critically considered. The conclusion becomes, that the mechanism of formation two-nuclear neurons is cellular fusion. Simultaneously the review confirms our representations about existence in nervous system sincitial interneural communications.

Due to environmental concerns such as global warming, needs the nuclear power is increasing. However, many expert engineers and technicians are now entering a period of retirement. And due to weak demands of new plant construction for long years, opportunity for technology learning/experience had been lost. Therefore, to secure human resource and to develop their ability are urgent issues for nuclear industries. Hitachi nuclear division continues efforts for technology transfer and human resource training. This paper describes the following two activities. (1) Improvement of common technical basis, and implementation of PDCA cycle. (2) Development of supporting tools to accelerate technology transfer through OJT (On the Job Training). (author)

Radioanalytical Chemistry for Automated Nuclear Waste Process Monitoring

International Nuclear Information System (INIS)

Egorov, Oleg B.; Grate, Jay W.; DeVol, Timothy A.

2004-01-01

This research program is directed toward rapid, sensitive, and selective determination of beta and alpha-emitting radionuclides such as 99Tc, 90Sr, and trans-uranium (TRU) elements in low activity waste (LAW) processing streams. The overall technical approach is based on automated radiochemical measurement principles, which entails integration of sample treatment and separation chemistries and radiometric detection within a single functional analytical instrument. Nuclear waste process streams are particularly challenging for rapid analytical methods due to the complex, high-ionic-strength, caustic brine sample matrix, the presence of interfering radionuclides, and the variable and uncertain speciation of the radionuclides of interest. As a result, matrix modification, speciation control, and separation chemistries are required for use in automated process analyzers. Significant knowledge gaps exist relative to the design of chemistries for such analyzers so that radionuclides can be quantitatively and rapidly separated and analyzed in solutions derived from low-activity waste processing operations. This research is addressing these knowledge gaps in the area of separation science, nuclear detection, and analytical chemistry and instrumentation. The outcome of these investigations will be the knowledge necessary to choose appropriate chemistries for sample matrix modification and analyte speciation control and chemistries for rapid and selective separation and preconcentration of target radionuclides from complex sample matrices. In addition, new approaches for quantification of alpha emitters in solution using solid-state diode detectors, as well as improved instrumentation and signal processing techniques for use with solid-state and scintillation detectors, will be developed. New knowledge of the performance of separation materials, matrix modification and speciation control chemistries, instrument configurations, and quantitative analytical approaches will

An integrated high-temperature water chemistry sensor (pH, E redox ) was developed for the establishment of the on-line water chemistry surveillance system in nuclear power plants. The basic performance of the integrated sensor was confirmed in high-temperature (280 .deg. C, 150kg/m 2 ) lithium borate solutions by using the relationship between the concentration of lithium ion and pH-E redox values. Especially, the effects of various environmental factors such as temperature, pressure, and flow rate on YSZ-based pH electrode were evaluated for ensuring the accuracy of high-temperature pH measurement. And the relationships between each water chemistry factor (pH, redox potential, electrical conductivity) were induced for enhancing the credibility of water chemistry measurement. In addition, on the basis of the evaluation of a nuclear plant design company, we suggested potential installation positions of the measurement system in a nuclear power plant

This report describes the activities of the Nuclear Science Division for the period of January 1, 1994, to December 31, 1994. This was a time of significant accomplishment for all of the programs in the Division. Assembly of the solar neutrino detector at the Sudbury Neutrino Observatory is well under way. All of the components fabricated by LBL were shipped to Sudbury early in the year and our efforts are now divided between assisting the assembly of the detector and preparing software for data analysis once the detector is operational in 1996. Much of the activity at the 88-Inch Cyclotron centered on Gammasphere. The open-quotes early implementationclose quotes phase of the detector ended in September. This phase was extremely successful, involving over 60 experiments with nearly 200 users from 37 institutions worldwide. The mechanical structure was installed and the final electronic system is expected to operate in March 1995. The Division concurrently hosted a conference on physics for large γ-ray detector arrays at the Clark Kerr Campus at UC Berkeley in August. This was a very successful meeting, reflecting the enthusiasm for this field worldwide. Also at the Cyclotron, the progress toward weak interaction experiments using ultra-thin sources passed a major milestone with the trapping of radioactive 21 Na atoms. We are now engaged in a major upgrade of the experimental area and the outlook is very promising for these novel experiments. Another highlight of research at the Cyclotron was the confirmation of element 106. This development allowed the original LLNL/LBL discovery team to move forward with their proposal to name this element seaborgium

The outcome of these investigations will be the knowledge necessary to choose appropriate chemistries for sample matrix modification and analyte speciation control and chemistries for rapid and selective separation and preconcentration of target radionuclides from complex sample matrices. In addition, new approaches for quantification of alpha emitters in solution using solid state diode detectors, as well as improved instrumentation and signal processing techniques for use with solid-state and scintillation detectors, will be developed. New knowledge of the performance of separation materials, matrix modification and speciation control chemistries, instrument configurations, and quantitative analytical approaches will provide the basis for designing effective instrumentation for radioanalytical process monitoring. Specific analytical targets include 99 Tc, 90Sr and

Nuclear approaches for compositional characterization has bright application prospect in forensic perspective towards assessment of nature and origin of seized material. The macro and micro physical properties of nuclear materials can be specifically associated with a process or type of nuclear activity. Under the jurisdiction of nuclear analytical chemistry as well as nuclear forensics, thrust areas of scientific endeavor like determination of radioisotopes, isotopic and mass ratios, analysis for impurity contents, arriving at chemical forms/species and physical parameters play supporting evidence in forensic investigations. The analytical methods developed for this purposes can be used in international safeguards as well for nuclear forensics. Nuclear material seized in nuclear trafficking can be identified and a profile of the nuclear material can be created

taking part in the proficiency test on the determination of 239 Pu, 241 Pu and 241 Am in mineral matrix, organised by the IAEA. Ten dust samples, delivered by the University of Bremen (Germany) were analysed for the presence of 238 Pu, 239+240 Pu, 241 Pu, 241 Am and 244 Cm. In 1999, the equipment of the Environmental Radioactivity Laboratory was enriched with a low- background liquid scintillator spectrometer (Wallac 1414-003 Guardian), which opened a whole new branch of possible work connected with determination of pure beta-emitters. First isotopes of interest were 90 Sr and 241 Pu accumulated in animal bones. For 90 Sr measurements, an extensive library of scintillation quenching corrections was prepared. The spectrometer was also applied for tests of the purity of 32 P for the Laboratory of Physical Chemistry. A new project on transfer of plutonium from forest soil and litter to fungi and plants has been started. It is a pilot study for a planned in-Lab experiment to be performed during the incoming year at the University of Extremadura, Caceres, Spain. Other projects conducted during 1999 in the Environmental Radioactivity Laboratory are described in short abstracts below. In the Laboratory of Physical Chemistry, the project on construction of the internal target assembly for isotope production was continued, in cooperation with the Institute's Division of Mechanical Construction and with the Cyclotron Section. At the same time, much investment was made into necessary renovations in the radiochemical laboratory. Research in the Laboratory was concentrated on preparation and evaluation of 32 P sources for intravascular brachytherapy. With the help of the Institute's Health Physics Laboratory, liquid Na 2 H 32 PO 4 sources were calibrated by TL dosimetry, and in cooperation with the Department of Nuclear Spectroscopy, some solid state sources containing 32 P were prepared.

International Nuclear Information System (INIS)

1997-12-01

The separation of actinide elements from various waste materials, produced either in nuclear fuel cycles or in past nuclear weapons production, represents a significant issue facing developed countries. Improvements in the efficiencies of the separation processes can be expected to occur as a result of better knowledge of the elements in these complex matrices. The Nuclear Science Committee of the OECD/NEA has established a task force of experts in actinide separation chemistry to review current and developing separation techniques and chemical processes. The report consist of eight chapters. In Chapter 1 the importance of actinide separation chemistry in the fields of waste management and its background are summarized.In Chapter 2 the types of waste streams are classified according to their relative importance, by physical form and by source of actinides. The basic data of actinide chemical thermodynamics, such as oxidation states, hydrolysis, complexation, sorption, Gibbs energies of formation, and volatility, were collected and are presented in Chapter 3. Actinide analyses related to separation processes are also mentioned in this chapter. The state of the art of actinide separation chemistry is classified in three groups, including hydrometallurgy, pyrochemical process and process based on fields, and is described in Chapter 4 along with the relationship of kinetics to separations. In Chapter 5 basic chemistry research needs and the inherent limitation on separation processes are discussed. Prioritization of research and development is discussed in Chapter 6 in the context of several attributes of waste management problems. These attributes include: mass or volume of waste; concentration of the actinide in the waste; expected difficulty of treating the wastes; short-term hazard of the waste; long-term hazard of the waste; projected cost of treatment; amount of secondary waste. Based on the priority, recommendations were made for the direction of future research

Chemistry of nuclear resources, technology, and waste

Keller, O.L. Jr.

1978-01-01

Chemistry is being called on today to obtain useful results in areas that have been found very difficult for it in the past, but new instrumentation and new theories are allowing much progress. The area of hydrolytic phenomena and colloid chemistry, as exemplified by the plutonium polymer problem, is clearly entering a new phase in which it can be studied in a much more controlled and understandable manner. The same is true of the little studied interfacial regions, where so much important chemistry occurs in solvent extraction and other systems. The studies of the adsorption phenomena on clays are an illustration of the new and useful modeling of geochemical phenomena that is now possible. And finally, the chemist is called upon to participate in the developement and evaluation of models for nuclear waste isolation requiring extrapolations of hundreds to hundreds of thousands of years into the future. It is shown that chemistry may be useful in keeping the extrapolations in the shorter time spans, and also in selecting the best materials for containment. 36 figures

The evolution of nuclear chemistry will be traced briefly, with special emphasis on the exciting and highly productive period of the war-time Metallurgical Laboratory from 1942 to 1946. In particular, the Fission Product Radiochemistry section at The University of Chicago, which underwent sequential fissions of its own to Oak Ridge and Los Alamos, will provide a major focus. The post-war spread of nuclear chemistry throughout the country and the establishment of the National Laboratories provided the setting for the Golden Age of the field. Throughout this period, the personality and character of Nathan Sugarman was clearly evident. Whether as teacher, researcher, colleague, critic, counselor, friend, or acquaintance, Sug's intelligence, warmth, humor, high standards, and quiet leadership make a lasting impression on a generation of nuclear chemists

Analytical chemistry of nuclear materials

International Nuclear Information System (INIS)

1963-01-01

The last two decades have witnessed an enormous development in chemical analysis. The rapid progress of nuclear energy, of solid-state physics and of other fields of modern industry has extended the concept of purity to limits previously unthought of, and to reach the new dimensions of these extreme demands, entirely new techniques have been invented and applied and old ones have been refined. Recognizing these facts, the International Atomic Energy Agency convened a Panel on Analytical Chemistry of Nuclear Materials to discuss the general problems facing the analytical chemist engaged in nuclear energy development, particularly in newly developing centre and countries, to analyse the represent situation and to advise as to the directions in which research and development appear to be most necessary. The Panel also discussed the analytical programme of the Agency's laboratory at Seibersdorf, where the Agency has already started a programme of international comparison of analytical methods which may lead to the establishment of international standards for many materials of interest.

Coordination chemistry of technetium as related to nuclear medicine

International Nuclear Information System (INIS)

Srivastava, S.C.; Richards, P.

1982-01-01

Significant advances have been made in the area of technetium coordination chemistry during the last five years. The main driving force behind this recent surge of interest in the field has been due to the practical application of technetium-99m in the rapidly growing speciality of nuclear medicine. Technetium-99 is one of the products of nuclear fission reactions, but it was the development of the molybdenum-99-technetium-99m generator about two decades ago that provided the basis for the development of radiopharmaceuticals routinely used in modern diagnostic applications. The chemistry of this element has proven to be quite rich owing to its multiple oxidation states and variable geometry. This can be attributed to its position in the middle of the periodic table. Diagnostic radiopharmaceuticals comprise predominantly III, IV and V oxidation states of Tc and involve a variety of coordination complexes. Even though the chemistry of Tc has been slow to evolve, recent synthetic advances have provided a more scientific basis for the study of a number of compounds with diverse coordination geometries and structures. Ligands with oxygen, nitrogen and sulfur donor atoms have been utilized to elucidate various aspects of the coordination chemistry of Tc. Single crystal X-ray structural analysis has been extensively used to characterize Tc complexes and thus construct a firm foundation for the study of synthetic and mechanistic aspects of the chemistry of this element.

2012-09-01

Water chemistry control technologies for nuclear power plants have been significantly enhanced over the past few decades to improve material and equipment reliability and fuel performance, and to minimize radionuclide production and transport. Chemistry Guidelines have been developed by the Electric Power Research Institute (EPRI) for currently operating plants and have been intermittently revised over the past twenty-five years for the protection of systems and components and for radiation management. As new plants are being designed for improved safety and increased power production, it is important to ensure that the designs consider implementation of state-of-the-art, industry developed water chemistry controls. In parallel, the industry will need to consider and update water chemistry guidelines as well as plant startup and operational strategies based on the advanced plant designs. EPRI has performed assessments of water chemistry control guidance or assumptions provided in design and licensing documents for several advanced plant designs. These designs include: Westinghouse AP1000 Pressurized Water Reactor AREVA US-EPR Pressurized Water Reactor Mitsubishi Nuclear Energy Systems/Mitsubishi Heavy Industries Advanced Pressurized Water Reactor Korea Hydro and Nuclear Power APR1400 Pressurized Water Reactor Toshiba Advanced Boiling Water Reactor (ABWR) General Electric-Hitachi Economic Simplified Boiling Water Reactor (ESBWR) The intent of these assessments was to identify key design differences in each of the new plant designs relative to the current operating fleet and to identify differences in water chemistry specifications or design assumptions provided in design and licensing documents for the plants in comparison to current EPRI Water Chemistry Guidelines. This paper provides a summary of the key results of these assessments. The fundamental design and operation of the advanced plants is similar to the currently operating fleet. As such, the new plants are

The research activities of the nuclear physics division (SPHN) of DAPNIA (Cea) take place within strong national and international collaborations. Its programs cover a broad range of topics in nuclear physics from low to high energies, they include the structure and dynamics of the nucleus, the structure of the nucleon, the search for phase transitions in nuclear matter, and contribution to the development of nuclear energy. Concerning the structure of the nucleus, SPHN is involved in the study of the structure of light exotic nuclei such as He 6-8 , C 10-11 , Ne 27 and in the study of shape coexistence in Kr isotopes. The experiments are performed at GANIL. SPHN is also involved in the study of the structure of Md 251 through experiments made in Finland. Near-barrier and sub-barrier fusion of light unstable nuclei and their respective stable isotopes with U 238 targets are studied in Louvain-la-Neuve (Belgium). Concerning nuclear phase transitions, the purpose of our activities is twofold: the study of the liquid-gas phase transition in nuclei at relatively low incident energies and the search for the quark-gluon plasma (QGP) at very high energies. We look for QGP signatures in 2 experiments: Phenix with the accelerator RHIC at Bnl and Alice at the LHC (CERN). Concerning the structure of the nucleon, SPHN is involved in 2 experimental programs both using electromagnetic probes, one to obtain information on the spin carried by the gluons in the proton (Compass at CERN) and the other to extract information on generalized parton distributions by means of deeply virtual Compton scattering (Clas at Jlab). Concerning nuclear energy, the activities are focused along 3 main lines: spallation studies, neutron cross-section measurements and application oriented modeling. (A.C.)

The chemical behavior of radioactive elements can differ from conventional wisdom because the number of atoms can be unusually small. Kinetic effects and unusual oxidation states are phenomena that make radiochemistry different from conventional analytic chemistry. The procedures developed at Los Alamos are designed to minimize these effects and provide reproducible results over a wide range of sample types. The analysis of nuclear debris has the additional complication of chemical fractionation and the incorporation of environmental contaminants. These are dealt with through the use of three component isotope ratios and the use of appropriate end members.

Nuclear energy is the only source available to the mankind to fulfill the continuous and ever increasing demand of energy. The public acceptance and popularity of nuclear energy depends to a large extent on management of radioactive waste. The nuclear waste management demands eco-friendly process/systems. This article highlights the sources of different types of radioactive liquid wastes generated in the nuclear installation and their treatment process. The radioactive liquid waste is classified mainly into three categories based on activity levels e.g. low, intermediate and high level. The management of radioactive liquid waste is very critical because of its 'mobility and liquid' nature. Secondly the liquid wastes have wide range of activity and chemistry spectrum and their volumes are also different. Hence the methods for management of different types of liquid wastes are also different. Mostly the treatment and conditioning processes are chemical processes. The chemistry involved in the treatment and conditioning of these wastes, problems related with chemistry for each processes and efforts to solve these problems, aspects of adoption on plant scale, etc., have been discussed in this article.

The European Analytical Column again has a somewhat different format. We have once more invited a guest columnist to give his views on various matters related to analytical chemistry in Europe. This year we have invited Prof. Manfred Grasserbauer of Vienna University of Technology to present some...... representing a major branch of chemistry, namely, analytical chemistry. The global financial crisis is affecting all branches of chemistry, but analytical chemistry in particular since our discipline by tradition has many close links to industry. We are already noticing a decreased industrial commitment...... with respect to new research projects and sponsoring of conferences. It is therefore important that we strengthen our efforts and that we keep our presence at analytical chemistry meetings and conferences unchanged.

Lee, Sang Hak; Kim, Chung Tae

1997-01-01

Water chemistry control is one of the most important tasks in order to maintain the reliability of plant equipments and extend the operating life of the plant. KEPCO and KOPEC developed a computerized tool for this purpose -ASCMS (advanced secondary chemistry monitoring system) which is able to monitor and diagnose the secondary water chemistry. A prototype system had been installed at KORI 3 nuclear power plant since April 1993 in order to evaluate the system performance. After the implementation of enhancements identified during the testing of the prototype, we have developed the advanced secondary monitoring system, ASCMS which is installed at 5 nuclear power plants and has been under operations since April 1997. The ASCMS comprises PC subsystem designed for data acquisition, data analysis, and data diagnosis. The ASCMS will provide overall information related to steam generator secondary side water chemistry problems and improve plant availability, reduce radiation exposure to workers, and reduce operating and maintenance costs. 6 figs

The highlight of the Argonne Physics Division during the past year (1985/86) has been the completion and dedication of the final superconducting linac stages of the ATLAS system and the beginning of the research program that utilizes the full capabilities of that system. The transition to using the full ATLAS and the new experimental area has been a smooth one and the research program is beginning to bear fruit. The experimental facilities have also come into operation with three major components, consisting of the first stage of a gamma detection system incorporating an array of Compton-suppressed germanium detectors and BGO total energy detectors, a magnetic spectrograph of the Enge split-pole design, with a focal-plane detector system adapted to heavy ions, and a new scattering facility with a number of features. Interesting new data are emerging on quasi-elastic processes, on the transition between fission and quasi-fission and the study of nuclear structure at high spin. The past year has also seen the merging of the nuclear research in the Argonne Chemistry Division, mostly in heavy-ion and medium-energy nuclear physics, with the Physics Division. The merger is leading to full cooperation within the larger group and will help broaden and strengthen the total effort in nuclear physics. In medium-energy physics the year has seen the successful execution of an experiment at the SLAC NPAS station to study the delta resonance in nuclei. Progress is being made in the effort at Fermilab on deep inelastic muon scattering, on the development of a tensor polarized gas deuterium target for use with storage rings, and on the LAMPF neutrino oscillation experiment. In theoretical nuclear physics an effort is continuing on investigating the relevant degrees of freedom in the microscopic dynamics of nuclei and the importance of three-body forces. 51 figs., 2 tabs.

In 1946, the Institute for Nuclear Physics Research (IKO) in Amsterdam was founded as a typical post World War II effort to cope with the surge in scientific research, primarily in the USA. At present, the Institute encompasses almost 250 workers - including a Philips research group - out of which nearly 30 are members of the Chemistry Department. In the beginning, the investigations dealt with more or less conventional tracerwork using long-lived radionuclides produced in nuclear reactors. This changed rapidly with the synchrocyclotron coming into operation in 1947. The present can be best characterized as a sort of a transition state. Emphasis has been laid upon more typical chemical aspects of the research program: a shift from ''nuclear'' chemistry to ''radio'' chemistry. The future is determined by the 500 MeV linear electron accelerator, dubbed MEA (Medium Energy Accelerator) already under construction. (T.G.)

Nuclear Physics Division is involved in research in nuclear and solid state physics. The year 1987 has been a fairly eventful one for the Division in the sense that several activities came to a high level of fruition. A beam of 5 + silicon ions accelerated to about 14 MeV in the BARC-TIFR Pelletron accelerator was obtained for the first time in September. Experiments on the cyclotron at Calcutta and the CN Van-de-Graaff accelerator at Trombay have continued. The latter continued to be heavily utilised for nuclear, chemical, materials and other applications in its twentysixth year of operation. For the neutron scattering programme at Dhruva Reactor two new diffractometers were commissioned, one of a conventional type and another based on a metre long position sensitive detectors (PSD). A neutron interferrometer was successfully operated at the CIRUS reactor. A modular CW argon laser giving a total power of about 2.7 watts has been incorporated with the Raman scattering spectrometer thus increasing the range of performable experiments. The modularity allows quick replacement of parts. A number of interesting investigations were carried out by the members of the Division; among others they include observations of quasi-molecular heavy ion resonances in Sisup(2s), anomalous behaviour of deep sub-barrier fission in uranium, crystalline to amorphous to crystalline transition in tetracyanoethylene, exceptional stability of the quasi-crystal Al 6 CuMg 4 and the development of a phenomenological mode to describe magnetisation curves in the new high-Tsub(c) superconductors. These and many other investigations are reported. (M.G.B.)

To prevent the corrosion problems on important components of nuclear power plants, the computerization methods of water chemistry and the analyses of corrosion failures were studied. A preliminary study on the computerization of water chemistry log-sheet data was performed using a personal computer with dBASE-III and LOTUS packages. Recent technical informations on a computerized online chemistry data management system which provides an efficient and thorough method of system-wide monitoring of utility's secondary side chemistry were evaluated for the application to KEPCO's nuclear power plants. According to the evaluation of water chemistry data and eddy current test results, it was likely that S/G tube defect type was pitting. Pitting is believed to result from excess oxygen in make-up and air ingress, sea-water ingress bycondenser leak, and copper in sludge. A design of a corrosion tests apparatus for the tests under simulated operational conditions, such as water chemistry, water flow, high temperature and pressure, etc., of the plant has been completed. The completion of these apparatus will make it possible to do corrosion tests under the conditions mentioned above to find out the cause of corrosion failures, and to device a counter measure to these. The result of corrosion tests with alloy-600 showed that the initiation of pits occurred most severely around 175 deg C which is lower than plant-operation temperature(300 deg C) while their propagation rate had trend to be maximum around 90 deg C. It was conformed that the use of Cu-base alloys in a secondary cooling system accelerates the formation of pits by the leaking of sea-water and expected that the replacement of them can reduce the failures of S/G tubes by pitting. Preliminary works on the examination of pit-formed specimens with bare eyes, a metallurgical microscope and a SEM including EDAX analysis were done for the future use of these techniques to investigate S/G tubes. Most of corrosion products

This document attempts to reconstruct the role played by the Chemical Technology Division (Chem Tech) of the Oak Ridge National Laboratory (ORNL) in the atomic era since the 1940`s related to the development and production of nuclear weapons and power reactors. Chem Tech`s early contributions were landmark pioneering studies. Unknown and dimly perceived problems like chemical hazards, radioactivity, and criticality had to be dealt with. New chemical concepts and processes had to be developed to test the new theories being developed by physicists. New engineering concepts had to be developed and demonstrated in order to build facilities and equipment that had never before been attempted. Chem Tech`s role was chemical separations, especially uranium and plutonium, and nuclear fuel reprocessing. With diversification of national and ORNL missions, Chem Tech undertook R&D studies in many areas including biotechnology; clinical and environmental chemistry; nuclear reactors; safety regulations; effective and safe waste management and disposal; computer modeling and informational databases; isotope production; and environmental control. The changing mission of Chem Tech are encapsulated in the evolving activities.

The Nuclear Science Facility at SJSU was first opened for classes in 1975. It is designed primarily for undergraduate teaching of nuclear chemistry, radiochemistry, tracer techniques, and radiation safety. Utilizing nearly $1.5 million in counting equipment alone, but excluding a reactor or accelerator, it allows simultaneous use of multiple counting assemblages for up to 20 individual students, even for advanced experiments with Ge/MCA units. Current academic programs include a B.S. Degree in Radiochemistry, an M.S. in Radiological Health Physics, and community outreach to grade schools (nearly 2,000 student-experiments for grades 7-12 were performed in AY88/89). To encourage nuclear chemistry as a potential area of study in graduate school, the US Department of Energy funded a special national Summer School in Nuclear Chemistry. This was first held at SJSU in 1984; summer 1990 will see the seventh such program taught

The role of post accident chemistry data in nuclear safety

International Nuclear Information System (INIS)

Bradshaw, R.W.; Caruthers, G.F.

1982-01-01

The NRC instituted the NUREG-0737 requirements as implementation of the Post-TMI Action Plan in October, 1980. Among these requirements was the capability to obtain chemistry samples of the reactor coolant and containment building atmosphere under post accident conditions. The quantitative criteria were, in general, beyond the capabilities of existing plant systems. As a consequence the nuclear industry expended substantial efforts to design and install the post-accident sampling systems necessary to comply with these criteria. With such efforts essentially complete, the task remains to establish the role that data provided by these systems would play in mitigating the consequences of a nuclear plant accident. This role definition must include a characterization of the timing and priority for the post accident chemistry data. This paper defines that role using the Safety Level and Safety Function concepts as a matrix

The Arizona Nuclear Power Project (ANPP), a three-reactor site located 50 miles west of Phoenix, Arizona, has developed and implemented a program for evaluating individual chemistry technician analytical performance on a routine basis. About 45 chemistry technicians are employed at the site, 15 at each operating unit. The technicians routinely perform trace level analyses for impurities of concern to PWRs. Each month a set of blind samples is provided by an outside vendor. The blind samples contain 16 parameters which are matrixed to approximate the PWR's primary and secondary cycles. Nine technicians receive the samples, three from each operating unit, and perform the required analyses. Acceptance criteria for successful performance on the blind parameters is based on the values found in the Institute of Nuclear Power Operations (INPO) Document 83-016, Revision 2, August 1989, Chemistry Quality Control Program. The goal of the program is to have each technician demonstrate acceptable performance on each of 16 analytical parameters. On completion of each monthly set, a summary report of all of the analytical results for the sample set is prepared. From the summary report, analytical bias can be detected, technician performance is documented, and overall laboratory performance can be evaluated. The program has been very successful at satisfying the INPO requirement that the analytical performance of each individual technician should be checked on at least a six-month frequency for all important parameters measured. This paper describes the program as implemented at the Palo Verde Nuclear Generating Station and provides a summary report and trend and bias graphs for illustrative purposes

Role of chemistry in uranium leaching from sand stone ore bodies by ISL technique (abstract)

International Nuclear Information System (INIS)

Sheikh, A.K.; Hanif, M.

2011-01-01

The importance of uranium for nuclear power generation is increasing day by day in the current energy requirement scenario. The energy sector is reverting to nuclear power generation in many countries. Keeping in view the limited availability of fossil fuels and the problems associated with its exploration. In situ leach mining of uranium is currently employed in many countries for extraction of uranium in soft rocks from subsurface where deposits are lying deeper and the cost of underground mining (UGM) are high. In situ leaching of uranium revolves around injection of leachant (usually bicarbonate) and oxidant into the host rock without disturbing the strata thereby solubilizing the uranium in solution form. The resultant leach is then pumped out and sent to processing plant for production of yellow cake. The Chemistry Division NMC-I, D. G. Khan plays a vital role in ISL Mining of uranium, starting from initial exploration of ore body, analysis of leach liquor and other liquid samples up to the final step of yellow cake formation. During all these analysis to ensure Quality control, Chemistry Division utilizes modern / updated analytical techniques e.g. Atomic Absorption Spectroscopy, Spectrophotometry, Fluorimetry and Potentiometry. R and D studies are also being carried out to optimize and economize the operational parameters accordingly. This presentation basically encompasses the role of Chemistry at various levels and stages at Mining Projects to achieve this goal. (author)

The following sentences highlight some of the technical activities carried out during 1991. They illustrate the diversity of programs and technical work performed within the Analytical Chemistry Division. Our neutron activation analysis laboratory at HFIR was placed into operation during 1991. We have combined inductively coupled plasma mass spectrometry (ICP/MS) with a preparation procedure developed at the Argonne National Laboratory to measure ultra-trace levels of U, Pu, Np, and Am in body fluids, primarily urine. Much progress has been made over the last year in the interfacing of an rf-powered glow discharge source to a double-focusing mass spectrometer. Preliminary experiments using electrospray ionization combined with ion trap mass spectrometry show much promise for the analysis of metals in solution. A secondary ion microprobe has been constructed that permits determination of the distribution of organic compounds less than a monolayer thick on samples as large as 1 cm diameter. Fourier transform mass spectrometry has been demonstrated to be a highly effective tool for the detailed characterization of biopolymers, especially normal and modified oligonucleotides. Much has been accomplished in understanding the fundamentals of quadrupole ion trap mass spectrometry. Work with ITMS instrumentation has led to the development of rapid methods for the detection of trace organics in environmental and physiological samples. A new type of time-of-flight mass spectrometer was designed for use with our positron ionization experiments. Fundamental research on chromatography at high concentrations and on gas-solid adsorption has continued. The preparation of a monograph on the chemistry of environmental tobacco smoke was completed this year.

In the Laboratory of Chemistry and Radiochemistry, research on chemistry of the transactinide elements 104(Rf), 105(Db) and 106(Sg) in model systems with their homologs (Zr, Hf, Nb, Ta, Mo, and W) was continued, and studies on ion-exchange and extraction behaviour of Tc, Re and Os as homologs of Bh(107) and Hs(108) were started. Basing on the law of periodicity, conditions for separation of superheavy elements Rf, Sg, and Bh were adjusted. A particularly important achievement was participation of our group in the third experiment in the world on aqueous chemistry of Sg, performed in the summer 1998 in GSI Darmstadt. The Environmental Radioactivity Laboratory, was continuing non-stop records of the ground-level atmospheric radioactivity. Besides, Pu content was determined in two-years collection of rainwater samples. An air monitoring station was recently equipped with a prototype γ-spectrometric scintillation system which, modem-coupled with the central server, will be tested in the Laboratory. For ultra-low-background measurements a muonic chamber was designed and made, and new spectrometer's background was recorded in various shielding configurations. Research on α-active and γ-active environmental contaminants in Antarctic samples, supplied by the Institute of Botany of the Jagiellonian University, resulted in an M.Sc. thesis defended in June 1998. Other cooperations of the Laboratory in 1998 have been the following: a) determination of 90 Sr and 137 Cs in wild animals bones (Institute of Nuclear Techniques, Technical University, Budapest, Hungary and Medical Academy, Bialystok, Poland); b) PIXE determinations of trace elements in ASS-500 air filters (Department 2 of the Institute) and mineralogical studies of collected dusts (Institute of Geological Sciences, Jagiellonian University and the Institute of Geography, Pedagogical University, Cracow); c) a-spectrometric determination of radium isotopes in river waters and bottom sediments (Institute of Geography

IAEA programme on water chemistry in nuclear power plants

International Nuclear Information System (INIS)

Nechaev, A.F.; Skjoeldebrand, R.

1988-01-01

The paper reviews the past future efforts of the IAEA, directed to ensure optimal water chemistry regimes in nuclear power plants. Corrosion of structural materials resulting from the interaction of the coolant with the internal surfaces comprising the primary heat transfer and auxiliary circuits of water reactors, creates two main problems. The first is an operational problem resulting in an increase in the core pressure drop or overheating of the fuel elements induced by crud buildup on the fuel cladding. The second problem is related to occupational radiation exposures arising from contamination of out-of-flux surfaces by corrosion products activated in the reactor core. These are the problems of reliability and safety which together with economics could be considered as the 'three whales' of nuclear power. The main goals of international cooperation in reactor water chemistry are: (1) to create a balanced and well-grounded methodological basis for corresponding regulatory and engineering solutions on a national level and (2) to improve 'the models and predictive capability of specialists for conditions that are different from or perhaps just beyond the realm of experience'. Continuing efforts are required to guarantee the highest reliability and safety standards under favorable economic indices of nuclear power plants, and to obtain understanding of such significant potential for solving the remaining problems.

Technetium chemistry is a young and developing field. Despite the limited knowledge of its chemistry, technetium is the workhorse for nuclear medicine. Technetium is also a significant environmental concern because it is formed as a byproduct of nuclear weapons production and fission-power generators. Development of new technetium radio-pharmaceuticals and effective environmental control depends strongly upon knowledge of basic technetium chemistry. The authors performed research into the basic coordination and organometallic chemistry of technetium and used this knowledge to address nuclear medicine and environmental applications. This is the final report of a three-year Laboratory-Directed Research and Development (LDRD) project at the Los Alamos National Laboratory (LANL)

Nuclear power plant conference 2010 (NPC 2010): International conference on water chemistry of nuclear reactor systems and 8th International radiolysis, electrochemistry and materials performance workshop

International Nuclear Information System (INIS)

2010-01-01

The Nuclear Plant Chemistry Conference was held in Quebec City, Quebec, Canada on October 3-7, 2010. It was hosted by the Canadian Nuclear Society and was held in Canada for the first time. This international event hosted over 300 attendees, two thirds from outside of Canada, mostly from Europe and and Far East. The conference is formally known as the International Conference on Water Chemistry of Nuclear Reactor Systems and is the 15th of a series that began in 1977 in Bournemouth, UK. The conference focussed on the latest developments in the science and technology of water chemistry control in nuclear reactor systems. Utility scientists, engineers and operations people met their counterparts from research institutes, service organizations and universities to address the challenges of chemistry control and degradation management of their complex and costly plants for the many decades that they are expected to operate. Following the four day conference, the 8th International Radiolysis, Electrochemistry and Materials Performance Workshop was held as associated, but otherwise free-standing event on Friday, October 8, 2010. It was also well attended and the primary focus was the effect of radiation on corrosion. When asked about the importance of chemistry in operating nuclear power plants, the primary organizers summarized it in the following statement: 'Once a nuclear plant is in operation, chemistry improvement is the only way to increase the longevity of the plant and its equipment'. The organisers of the 2010 Workshop and the NPC 2010 conference decided that these two events would be held consecutively, as previous, but for the first time the organization and registration would be shared, which proved to be a winning combination by the attendance.

MADNESS applied to density functional theory in chemistry and nuclear physics

International Nuclear Information System (INIS)

We describe some recent mathematical results in constructing computational methods that lead to the development of fast and accurate multiresolution numerical methods for solving quantum chemistry and nuclear physics problems based on Density Functional Theory (DFT). Using low separation rank representations of functions and operators in conjunction with representations in multiwavelet bases, we developed a multiscale solution method for integral and differential equations and integral transforms. The Poisson equation, the Schrodinger equation, and the projector on the divergence free functions provide important examples with a wide range of applications in computational chemistry, nuclear physics, computational electromagnetic and fluid dynamics. We have implemented this approach along with adaptive representations of operators and functions in the multiwavelet basis and low separation rank (LSR) approximation of operators and functions. These methods have been realized and implemented in a software package called Multiresolution Adaptive Numerical Evaluation for Scientific Simulation (MADNESS)

Numerical verification of equilibrium chemistry software within nuclear fuel performance codes

A numerical tool is in an advanced state of development to compute the equilibrium compositions of phases and their proportions in multi-component systems of importance to the nuclear industry. The resulting software is being conceived for direct integration into large multi-physics fuel performance codes, particularly for providing transport source terms, material properties, and boundary conditions in heat and mass transport modules. Consequently, any numerical errors produced in equilibrium chemistry computations will be propagated in subsequent heat and mass transport calculations, thus falsely predicting nuclear fuel behaviour. The necessity for a reliable method to numerically verify chemical equilibrium computations is emphasized by the requirement to handle the very large number of elements necessary to capture the entire fission product inventory. A simple, reliable and comprehensive numerical verification method called the Gibbs Criteria is presented which can be invoked by any equilibrium chemistry solver for quality assurance purposes.

Schunk, J.; Patek, G.; Pinter, T.; Tilky, P.; Doma, A.; Osz, J.

2010-01-01

The primary water chemistry of the four identical units of Paks Nuclear Power Plant has been developed based on Western-type PWR units, taking into consideration some Soviet-Russian modifications. The political changes in 90s have also influenced the water chemistry specifications and directions. At PWR units the transition operational modes have been developed while in case of VVER units - in lack of central uniform regulation - this question has become the competence and responsibility of each individual plant. This problem has resulted in separate water chemistry developments with a considerable time delay. The needs for life-time extensions all over the World have made the development of start-up and shut-down chemistry procedures extremely important, since they considerably influence the long term and safe operation of plants. The uniformly structured limit value system, the principles applied for the system development, and the logic schemes for actions to be taken are discussed in the paper, both for normal operation and transition modes.

This report summarizes the scientific research carried out within the Nuclear Science Division between July 1, 1981, and September 30, 1982. Heavy-ion investigations continue to dominate the experimental and theoretical research efforts. Complementary programs in light-ion nuclear science, in nuclear data evaluation, and in the development of advanced instrumentation are also carried out. Results from Bevalac experiments employing a wide variety of heavy ion beams, along with new or upgraded detector facilities (HISS, the Plastic Ball, and the streamer chamber) are contained in this report. These relativistic experiments have shed important light on the degree of equilibration for central collisions, the time evolution of a nuclear collision, the nuclear density and compressional energy of these collisions, and strange particle production. Reaction mechanism work dominates the heavy-ion research at the 88-Inch Cyclotron and the SuperHILAC. Recent experiments have contributed to our understanding of the nature of light-particle emission in deep-inelastic collisions, of peripheral reactions, incomplete fusion, fission, and evaporation. Nuclear structure investigations at these accelerators continue to be directed toward the understanding of the behavior of nuclei at high angular momentum. Research in the area of exotic nuclei has led to the observation at the 88-Inch Cyclotron of the β-delayed proton decay of odd-odd T/sub z/ = -2 nuclides; β-delayed proton emitters in the rare earth region are being investigated at the SuperHILAC

Development of Iridium Solid-state Reference Electrode for the Water Chemistry Status Measurement in Nuclear Power Plants

International Nuclear Information System (INIS)

Ku, Heekwon; Lim, Dongseok; Cho, Jaeseon

2013-01-01

The result of ECP measurement of piping material in nuclear power plant at low temperature using the developed iridium (SSRE) reference electrode is approximately -0.370V. Based on the various results of this study, the developed iridium (SSRE) reference electrode can be applied to the water chemistry environments of nuclear power plant. Various metallic materials used in a nuclear power plant have been exposed to a variety of water chemistry environments and the corrosion of metallic materials occurs due to the reactions between metal structures and water chemistry environments. Therefore, the management of the water chemistry factors is needed to prevent corrosion. The chemical factors affecting the corrosion are pH and Electrochemical Corrosion Potential (ECP). The world-wide studies suggest that ECP and pH are effective indicators for preventing the material damage from water chemistry condition. ECP and pH should be measured as the reference electrodes, and should show stable potential characteristics with fast responses. In this study, the iridium reference electrodes using a solid-state metal oxide electrode has been developed to measure effective indicators such as ECP and pH. The iridium (SSRE) reference electrode for the ECP measurement in water chemistry environment of nuclear power plants has been developed. A calibration for water chemistry measurement was performed by potential measurement of iridium (SSRE) reference electrode with Ag/AgCl (SSRE) reference electrode. The result exhibited a stable potential for 117 hours and a super-Nernst ian response with 63.12mV/p H. In this study, the iridium (SSRE) reference electrode shows super-Nernst ian characteristic and it may be caused by the property of electrolytically coated iridium oxide. Considering the long-term stability of the developed electrode, it is possible to apply as a reference electrode through calibration procedure

Water chemistry: cause and control of corrosion degradation in nuclear power plants

International Nuclear Information System (INIS)

Kain, Vivekanand

2008-01-01

The corrosion degradation of a material is directly determined by the water chemistry, material (composition, fabrication procedure and microstructure) and by the stress/strain in the material under operating conditions. Water chemistry plays an important role in both uniform corrosion and localized forms of corrosion of materials. Once we understand how water chemistry is contributing to corrosion of a material, it is logical to modify/change that water chemistry to control the corrosion degradation. In nuclear power plants, different water chemistries have been used in different components/systems. This paper will cover the origin of corrosion degradation in the Primary Heat Transport system of different reactor types, Steam Generator tubing, secondary circuit pipelines, service water pipelines and auxiliary systems and establish the role of water chemistry in causing corrosion degradation. The history of changes in water chemistry adopted in these systems to control corrosion degradation is also described. It is shown by examples that there is an obvious limitation in changing water chemistry to control corrosion degradation and in those cases, a change of material or change of the state of stresses/fabrication procedure becomes necessary. The role of water chemistry as a causative factor and also as a controlling parameter on particular types of corrosion degradation e.g. stress corrosion cracking, flow accelerated corrosion, pitting, crevice corrosion is illustrated. It will be shown that increase in dissolved oxygen content (due to radiolysis in nuclear reactors) is sufficient to make even the de-mineralized water to cause stress corrosion cracking in Boiling Water Reactors. Hydrogen Water Chemistry (by hydrogen injection) to control dissolved oxygen is shown to control the stress corrosion cracking. However, it is not possible to control dissolved oxygen at all parts of the Boiling Water Reactors. Therefore, a further refinement in terms of noble metal

New horizons for nuclear and radioanalytical chemistry laboratories

International Nuclear Information System (INIS)

Bode, P.

2005-01-01

Nuclear and radiochemistry are reported to suffer from a worldwide depression in support in the academic curriculum. The visibility of nuclear research groups is weak in general as can be illustrated by the low citation impact factors of the nuclear science related journals. Moreover, the use of nuclear techniques over other techniques is often insufficiently justified. Although in many countries a shortage in radiochemists is forecasted to occur by the end of this decade -and ample jobs becoming available-, students in chemistry and physics seem to prefer a career in contemporary sciences such as biotechnology, nanotechnology and genomics. Much of the research in these sciences is related to organic compounds and biomolecules or deals with elements that seemingly have little or no opportunities to be studied using radionuclides and (nuclear) radiation. Laboratories operating nuclear analytical techniques therefore need to use their creativity finding ways for participation in the scientific areas that are booming at the beginning of the 21st century. It requires an open mind on the strengths and weaknesses of existing techniques, and a departure from traditional views on measurement, analysis and even sources for activation. The unique features of using radiotracers and activatable tracers need again to be explored. Some radiochemistry laboratories at large (national) research centers have already converted their traditional technique-oriented research into more problem-oriented research, combining nuclear and complimentary non-nuclear techniques. Smaller laboratories have fewer opportunities for such holistic approaches but there are still a variety of nuclear and radiochemical techniques that fruitfully can be applied in these sciences and which also may turn attention towards the potentials of nuclear research reactor facilities, (nuclear) radiation and radionuclides, contributing to the sustainability of nuclear analytical groups.

Nuclear inner membrane fusion facilitated by yeast Jem1p is required for spindle pole body fusion but not for the first mitotic nuclear division during yeast mating.

Nishikawa, Shuh-ichi; Hirata, Aiko; Endo, Toshiya

2008-11-01

During mating of budding yeast, Saccharomyces cerevisiae, two haploid nuclei fuse to produce a diploid nucleus. The process of nuclear fusion requires two J proteins, Jem1p in the endoplasmic reticulum (ER) lumen and Sec63p, which forms a complex with Sec71p and Sec72p, in the ER membrane. Zygotes of mutants defective in the functions of Jem1p or Sec63p contain two haploid nuclei that were closely apposed but failed to fuse. Here we analyzed the ultrastructure of nuclei in jem1 Delta and sec71 Delta mutant zygotes using electron microscope with the freeze-substituted fixation method. Three-dimensional reconstitution of nuclear structures from electron microscope serial sections revealed that Jem1p facilitates nuclear inner-membrane fusion and spindle pole body (SPB) fusion while Sec71p facilitates nuclear outer-membrane fusion. Two haploid SPBs that failed to fuse could duplicate, and mitotic nuclear division of the unfused haploid nuclei started in jem1 Delta and sec71 Delta mutant zygotes. This observation suggests that nuclear inner-membrane fusion is required for SPB fusion, but not for SPB duplication in the first mitotic cell division.

One of the main objectives for the plant operator of a Nuclear Power Plant is to protect the Steam Generators (SG) during the lifetime of the plant by ensuring a safe and reliable operation. The SGs serve as an important barrier to prevent the spread of contamination out of the primary circuit. One the other hand impurities are accumulated within the SGs leading to extreme chemical and physical conditions. The application of an optimized water chemistry treatment of the secondary side is essential to ensure a good performance of the steam generators. (Author)

The ANL Physics Division traces its roots to nuclear physics research at the University of Chicago around the time of the second world war. Following the move from the University of Chicago out to the present Argonne site and the formation of Argonne National Laboratory: the Physics Division has had a tradition of research into fundamental aspects of nuclear and atomic physics. Initially, the emphasis was on areas such as neutron physics, mass spectrometry, and theoretical studies of the nuclear shell model. Maria Goeppert Maier was an employee in the Physics Division during the time she did her Nobel-Prize-winning work on the nuclear shell model. These interests diversified and at the present time the research addresses a wide range of current problems in nuclear and atomic physics. The major emphasis of the current experimental nuclear physics research is in heavy-ion physics, centered around the ATLAS facility (Argonne Tandem-Linac Accelerator System) with its new injector providing intense, energetic ion beams over the fill mass range up to uranium. ATLAS is a designated National User Facility and is based on superconducting radio-frequency technology developed in the Physics Division. A small program continues in accelerator development. In addition, the Division has a strong program in medium-energy nuclear physics carried out at a variety of major national and international facilities. The nuclear theory research in the Division spans a wide range of interests including nuclear dynamics with subnucleonic degrees of freedom, dynamics of many-nucleon systems, nuclear structure, and heavy-ion interactions. This research makes contact with experimental research programs in intermediate-energy and heavy-ion physics, both within the Division and on the national and international scale. The Physics Division traditionally has strong connections with the nation's universities. We have many visiting faculty members and we encourage students to participate in our

Full text: Full text: Water chemistry control is one of the key technologies to establish safe and reliable operation of nuclear power plants. Continuous and collaborative efforts of plant manufacturers and plant operator utilities have been focused on optimal water chemistry control, for which, a trio of requirements for water chemistry, a) better reliability of reactor structures and fuels, b) lower occupational exposure, and c) fewer radwaste sources, should be simultaneously satisfied. The research committee related to water chemistry of the Atomic Energy Society of Japan has played important roles to enhance improvement in water chemistry control, to share knowledge and experience with water chemistry among plant operators and manufacturers, to establish common technological bases for plant water chemistry and then to transfer them to the next generation related to water chemistry. Furthermore, the committee has tried to contribute to arranging R and D proposals for further improvement in water chemistry control through road map planning

In meiosis, two rounds of nuclear division occur consecutively without DNA replication between the divisions. We isolated a fission yeast mutant in which the nucleus divides only once to generate two spores, as opposed to four, in meiosis. In this mutant, we found that the initiation codon of the slp1 + gene is converted to ATA, producing a reduced amount of Slp1. As a member of the Fizzy family of anaphase-promoting complex/cyclosome (APC/C) activators, Slp1 is essential for vegetative growth; however, the mutant allele shows a phenotype only in meiosis. Slp1 insufficiency delays degradation of maturation-promoting factor at the first meiotic division, and another APC/C activator, Fzr1, which acts late in meiosis, terminates meiosis immediately after the delayed first division to produce two viable spores. © 2017 Federation of European Biochemical Societies.

In the papers presented bellow the activities of the Department of Nuclear Physical Chemistry in 1994 are presented. A further effort was made towards routine production of neutron-deficient isotopes for nuclear medicine - and namely {sup 67} Ga and {sup 139} Ce. Small activities of {sup 111} In were produced by the {alpha} bombardment of Ag target. In order to improve the {sup 111} In production the deuterons reaction with cadmium target was studied. The other field of the Department research is studying of the physicochemical properties of transactinoid elements (104,105, 106). The Department is also engaged in works of the National Network of Early Detection of Radioactive Contamination in Air. In this section, apart of the detail descriptions of mentioned activities, the information about personnel employed in the Department, papers and reports published in 1994, contribution to conferences and grants are also given.

This document reports on the work done by the Nuclear Technology Programs of the Chemical Technology Division, Argonne National Laboratory, in the period April--September 1990. These programs involve R&D in three areas: applied physical chemistry, separation science and technology, and nuclear waste management. The work in applied physical chemistry includes investigations into the processes that control the release and transport of fission products under accident-like conditions in a light water reactor, the thermophysical properties of the metal fuel in the Integral Fast Reactor, and the properties of selected materials in environments simulating those of fusion energy systems. In the area of separation science and technology, the bulk of the effort is concerned with developing and implementing processes for the removal and concentration of actinides from waste streams contaminated by transuranic elements. In the area of waste management, investigations are underway on the performance of materials in projected nuclear repository conditions to provide input to the licensing of the nation`s high-level waste repositories.
