Book excerpt: In spite of the large number of nuclear plants in the general category of operating, under construction, or planned, few had produced surveillance data by the end of 1968. Many programs are planned, however, and for perspective it may be of value to consider the reactors for which data on anticipated increase in NDT and planned surveillance are available. The small number of operating plants for which surveillance programs are now available limit severely the degree of specificity in tabulations of descriptive surveillance data.

Book Synopsis Chapter 7--The Utility Industry and Reactor Surveillance by : RB. Jenkins
Download or read book Chapter 7--The Utility Industry and Reactor Surveillance written by RB. Jenkins and published by . This book was released on 1983 with total page 11 pages. Available in PDF, EPUB and Kindle. Book excerpt: Every commercial nuclear power reactor pressure vessel (RPV) is required to have a reactor vessel surveillance program at the time of plant licensing. The program is part of a continuing structural integrity assessment of the RPV. As such, the surveillance program supplements Section III of the American Society of Mechanical Engineers (ASME) Code [1],1 which is the design basis for nuclear power plant component pressure boundaries. The Code assumes that the materials of construction are ductile in the evaluation and design of all components. The surveillance program for each RPV is intended to provide assurance of continued applicability of the ASME Code, Appendix G, assessment of that RPV's operating limits. This assessment ensures that the RPV is always in a condition which precludes the unstable propagation of flaws in the vessel wall material.

Download or read book Chapter 3--Army Reactor Vessel Surveillance and Vessel Examination written by and published by . This book was released on 1970 with total page 33 pages. Available in PDF, EPUB and Kindle. Book excerpt: Among the very earliest power producing reactors were those designed and constructed for the Army. They were built under the Army package power reactor (APPR) concept that dictated small pressure vessels and high flux cores to yield a proportionately high power output for a small physical plant. Because these characteristics result in high fluxes at the pressure vessel, the Army reactors have experienced embrittlement at rates considerably in excess of that exhibited by larger, commercial power reactors. The experience of the Army reactor program can be looked upon as being highly compressed, potential projections of the problems that may be faced by commercial power reactors in the future. The lower operating temperatures and the different, radiation-sensitive steels of the Army reactors accentuate their implications to commercial reactors. For these reasons and the fact that one, the PM-2A, was used as a vessel test experiment for failure analysis, the Army surveillance programs are reviewed here in depth.

Book Synopsis Chapter 8-Review and Analysis of Reactor Vessel Surveillance Programs by : LE. Steele
Download or read book Chapter 8-Review and Analysis of Reactor Vessel Surveillance Programs written by LE. Steele and published by . This book was released on 1983 with total page 46 pages. Available in PDF, EPUB and Kindle. Book excerpt: The problem of neutron radiation embrittlement of reactor pressure vessel steels has been addressed in earlier chapters by direct review of specific vessel surveillance programs. To end this study, all available surveillance results are summarized and analyzed within the context of current codes, rules, and standards. The results provide bases for certain modifications of future surveillance programs, surveillance analysis procedures and, possibly, for guiding criteria for developing Federal regulations and voluntary consensus standards and codes.

Book Synopsis Safety and Security of Commercial Spent Nuclear Fuel Storage by : National Research Council
Download or read book Safety and Security of Commercial Spent Nuclear Fuel Storage written by National Research Council and published by National Academies Press. This book was released on 2006-02-19 with total page 126 pages. Available in PDF, EPUB and Kindle. Book excerpt: In response to a request from Congress, the Nuclear Regulatory Commission and the Department of Homeland Security sponsored a National Academies study to assess the safety and security risks of spent nuclear fuel stored in cooling pools and dry casks at commercial nuclear power plants. The information provided in this book examines the risks of terrorist attacks using these materials for a radiological dispersal device. Safety and Security of Commercial Spent Nuclear Fuel is an unclassified public summary of a more detailed classified book. The book finds that successful terrorist attacks on spent fuel pools, though difficult, are possible. A propagating fire in a pool could release large amounts of radioactive material, but rearranging spent fuel in the pool during storage and providing emergency water spray systems would reduce the likelihood of a propagating fire even under severe damage conditions. The book suggests that additional studies are needed to better understand these risks. Although dry casks have advantages over cooling pools, pools are necessary at all operating nuclear power plants to store at least the recently discharged fuel. The book explains it would be difficult for terrorists to steal enough spent fuel to construct a significant radiological dispersal device.

Book Synopsis Chapter 1--The Bases for Surveillance Programs by : LE. Steele
Download or read book Chapter 1--The Bases for Surveillance Programs written by LE. Steele and published by . This book was released on 1983 with total page 14 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Metal Properties Council (MPC) has accepted the task of obtaining data on the properties of metals in critical areas of special need for industry in the United States (U.S.). One such area involves data on radiation effects in metals used as nuclear reactor pressure vessels. The MPC Subcommittee 6 on Materials for Nuclear Reactors, among other tasks, seeks information on availability and applicability, as well as the interpretation of data on radiation effects in reactor structural materials. In 1968, Subcommittee 6 sponsored an analytical review of data produced by periodic removal of surveillance capsules for assessing radiation effects on operating reactor pressure vessels. This work was prepared for the MPC by L. E. Steele and C. Z. Serpan, Jr., and was published in 1970 by ASTM as Special Technical Publication (STP) 481, entitled Analysis of Reactor Vessel Radiation Effects Surveillance Programs [1].

Download or read book Chapter 6--Surveillance Programs Critique and Recommendations written by and published by . This book was released on 1970 with total page 22 pages. Available in PDF, EPUB and Kindle. Book excerpt: The most important factors of any reactor pressure vessel surveillance program are: (1) it provides for the irradiation of steel from the actual pressure vessel, (2) the irradiation location is as close as physically possible to the vessel wall with the irradiation temperature and neutron spectrum duplicating those for the reactor vessel. These criteria thus provide a very useful measure of the value to be vested in the results of each reactor vessel surveillance program discussed.

Book Synopsis Chapter 3--Radiation Surveillance Program for Combustion Engineering, Inc. Reactor Vessel Materials by : JJ. Koziol
Download or read book Chapter 3--Radiation Surveillance Program for Combustion Engineering, Inc. Reactor Vessel Materials written by JJ. Koziol and published by . This book was released on 1983 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Radiation Surveillance Program for Combustion Engineering (C-E) Reactor Vessel Materials is designed to provide the operating utility with the capability of determining the radiation-induced changes in the mechanical and fracture toughness properties of the materials in the region of the reactor vessel encompassing the core. The term "materials" is used to collectively describe the metallurgical characteristics of base metal, deposited weld metal, and the heat-affected-zone (HAZ) metal. By conducting such determinations periodically, the neutron-induced changes in the initial reference temperature (RTNDT) can be assessed by direct measurement and the conservatism in the planned adjustments to plant operating parameters to compensate for the RTNDT changes can be verified.
