PRA Implementation Plan (1994 to 1999)

In a memorandum to the NRC's Executive Director for Operations, dated November 2, 1993, the directors from the agency's Office of Nuclear Reactor Regulation (NRR), Office of Nuclear Material Safety and Safeguards (NMSS), Office for Analysis and Evaluation of Operational Data (AEOD), and Office of Nuclear Regulatory Research (RES) concurred on the need to systematically expand the use of PRA within the agency. On that basis, the NRC subsequently developed the PRA Implementation Plan to ensure the increased use of PRA in regulatory activities. In particular, the PRA Implementation Plan was intended to provide an overview of each office's activities in the field of PRA. Toward that end, the PRA Implementation Plan was updated periodically until it was replaced by the RIRIP.
