[en] Studies resulting from Three Mile Island (TMI) showed that corrections were needed in information processing, operator training and procedures, and certain aspects of the safety review process. These have been undertaken by industry and NRC and the results are positive. New safety instructions have been set up. The Nuclear Safety Analysis Center (NSAC) is providing a focus for analysis of issues which have generic elements affecting a number of plants of similar or related design. The Institute of Nuclear Power Operations (INPO) is setting industry standards for training and certification of operators and supervisory personnel, and for training of the managerial chain which oversees safety practices. Changes in procedures and in some design features called for in the recommendations of the NRC Lessons Learned Task Force (NUREG-0578) have been simplemented by utilities. Other requirements included in the NRC Action Plan (NUREG-0660) and its companion document clarification of TMI Action Plan Requirements (NUREG-0737), are also being addressed. Improved operator training and emergency procedures provide a continuing opportunity to make safety gains. Problems remain to be faced in the regulatory and political arenas. The long-term licensing trend will be affected by the manner in which degraded core issues and the development of a safety goal proceed. The Industry Degraded Core Rulemaking (IDCOR) program has been undertaken to develop the nuclear industry's position in anticipation of an impending rulemaking. Both industry and NRC are working on the development of a safety goal and standard risk assessment methodology. (AF)
