Southern California Edison Company (SCE) is the majority owner and the operator of the three-unit San Onofre Nuclear Generating Station (SONGS) located on the Pacific coast between Los Angeles and San Diego. Its major goals for SONGS are reflected in the motto, Safety, Compliance and Excellence, which follow the company initials, SCE. The goal of excellence in unit operations includes the need to ensure that incidents that challenge plant safety systems do not occur. On November 21, 1985, an incident occurred at San Onofre Unit 1 which involved two separate material condition deficiencies. This incident represented a challenge to plant safety systems which was avoidable, but which had not been prevented by the authors existing programs for monitoring plant material condition. With input and suggestions from the US Nuclear Regulatory Commission (NRC) regional management, SCE developed and implemented two programs that are intended to achieve specific goals for reestablishing and systematically maintaining the material condition throughout the plant in safety-related and in nonsafety-related areas at a standard which will maintain for the next 20 yr the record of safe operation of San Onofre Unit 1 which it has accumulated in its first almost 20 yr.
