Generic Evaluation of Feedwater Transients and Small Break Loss-of-Coolant Accidents in GE-Designed Operating Plants and Near-Term Operating License Applications

摘要

The results of the Bulletins and Orders Task Force's generic evaluation of feedwater transients, small break loss-of-coolant accidents, and other Three Mile Island Unit 2 unrelated events for General Electric Company-designed operating plants and near-term operating license applications to confirm or establish the bases for the continued safe operation of the operating plants are summarized. As a result of its review, the Bulletins and Orders Task Force has concluded that (1) the continued operation of the General Electric Company-designed operating plants is acceptable provided that certain actions related to the plants' designs and operation, and training of operators are implemented consistent with the recommended implementation schedule, and (2) the actions taken by the licensees with General Electric Company-designed operating plants in response to Office of Inspection and Enforcement Bulletin 79-08 provide added assurance for the protection of the health and safety of the public. In addition, the Bulletins and Orders Task Force has independently confirmed the safety significance of those related actions recommended by other Office of Nuclear Reactor Regulation task forces.
