Abstract
On April 3, 1979, a group of utility representatives met in the Washington, D.C., offices of Edison Electric Institute (EEI) to assess the potential support for licensing, on a generic basis, the RETRAN computer code. More than 5 yr later, on September 3, 1984, the U.S. Nuclear Regulatory Commission (NRC) issued the safety evaluation report (SER) for EPRI CCM-5 and EPRI NP-1850-CCM. The motives for embarking on this rather lengthy process were: 1. to increase the NRC's understanding of and hence confidence in the RETRAN code; 2. to provide for a thorough review of the code independent of a specific utility's docket; 3. to reduce the effort associated in obtaining NRC acceptance of utility-specific applications. Provided in this paper is a short history of the RETRAN review effort followed by a comparison of the RETRAN process to that typically followed by a vendor in gaining approval for a topical report.
