Reprocessing Of Long-Cooled Nuclear Fuel: Process Description And Plant Design , Okan H. Zabunoglu Jan 1988

Reprocessing Of Long-Cooled Nuclear Fuel: Process Description And Plant Design , Okan H. Zabunoglu

Retrospective Theses and Dissertations

Purex reprocessing of 10-year cooled LWR fuel was investigated. The three major areas of research were (1) process description and flowsheet calculations, (2) plant design, and (3) cost estimation. Involvement of nearly 13 times less radioactivity in the 10-year cooled fuel than that in the 150-day (standard cooling time) cooled fuel, and the adoption of coprocessing of U and Pu in a new flowsheet rather than the complete partitioning of the standard purex method resulted in several simplifications in process and design over the standard purex method handling 150-day cooled fuel, leading to a simpler and more economic design for ...


Implementation Of An Expert System For Xenon Spatial Control In Pressurized Water Reactors , Sun-Kyo Chung Jan 1988

Implementation Of An Expert System For Xenon Spatial Control In Pressurized Water Reactors , Sun-Kyo Chung

Retrospective Theses and Dissertations

Most commercial pressurized water reactors are unstable to xenon oscillations that occur during load-follow operation;Control of the axial xenon oscillations is a knowledge- and experience-intensive activity for reactor operators. To aid reactor operators in the control of axial xenon oscillations, an advisory expert system was developed;A rule-based expert system shell, INSIGHT2+, was used to build the expert system which was interfaced with a microcomputer-based core control model of a pressurized water reactor, graphic engine, and data base;A core control model described by one-group diffusion theory with moderator temperature and xenon feedbacks was used to develop heuristic control ...
