Abstract

This safety evaluation report (SER) documents the technical review of the Limerick Generating Station (LGS), Units 1 and 2, license renewal application (LRA) by the United States Nuclear Regulatory Commission (NRC) staff (the staff). By letter dated June 22, 2011, Exelon Generation Company, LLC submitted the LRA in accordance with Title 10 of the Code of Federal Regulations Part 54, “Requirements for Renewal of Operating Licenses for Nuclear Power Plants.” Exelon requests renewal of the LGS Units 1 and 2 operating licenses (Operating License Nos. NPF-39 and NPF-85) for a period of 20 years beyond the current expiration at midnight October 26, 2024, and June 22, 2029, respectively. LGS is located approximately 21 miles northwest of Philadelphia, PA. The NRC issued the LGS Units 1 and 2 construction permits on June 19, 1974, and the operating licenses for LGS Unit 1 on August 8, 1985, and LGS Unit 2 on August 25, 1989. LGS Units 1 and 2 are of a boiling-water reactor design. General Electric supplied the nuclear steam supply system and Bechtel originally designed and constructed the balance of the plant. LGS Units 1 and 2 both have a licensed power output of 3,515 megawatts thermal.
