Safety Evaluation Report Related to the Operation of Comanche Peak Stream Electric Station, Units 1 and 2, Docket Nos. 50-445 and 50-446, Texas Utilities Electric Company, et al. Supplement No. 14

摘要

Supplement 14 to the Safety Evaluation Report related to the operation of the Comanche Peak Steam Electric Station (CPSES), Units 1 and 2 (NUREG-0797), has been prepared by the Office of Special Projects of the U.S. Nuclear Regulatory Commission (NRC). The facility is located in Somerville County, Texas, approximately 40 miles southwest of Fort Worth, Texas. This supplement presents the staff's evaluation of the applicants' Corrective Action Program (CAP) related to large and small bore piping and pipe supports which was developed to resolve various design issues raised by the Atomic Safety and Licensing Board (ASLB), the intervenor Citizens Association for Sound Energy (CASE), the Comanche Peak Response Team (CPRT), Cygna Energy Services (Cygna), and the NRC Staff. The NRC staff concludes that the CAP establishes a comprehensive program for resolving the technical concerns identified by the ASLB, CASE, CPRT, Cygna, and the NRC staff and its implementation ensures that the design of large and small bore piping and pipe supports at CPSES satisfies the applicable requirements of 10 CFR Part 50.
