SNC, the licensee is the holder of Renewed Facility Operating License Nos. NPF68 and NPF81, which authorize operation of Vogtle Electric Generating Plant Vogtle, Units 1 and 2, respectively. The licenses provide, among other things, that the facility is subject to all applicable rules, regulations, and orders of the U.S.
Nuclear Regulatory Commission NRC, the Commission now or hereafter in effect. The facility consists of two pressurized-water reactors PWRs located in Burke County, Georgia.
In 1996, the NRC identified Generic Safety Issue GSl-191 associated with the effects of debris accumulation on PWR sump performance during designbasis accidents Agencywide Documents Access and Management System ADAMS Accession No.
ML030160807. As part of the actions to resolve GSl-191, the NRC issued Generic Letter GL 200402, Potential Impact of Debris Blockage on Emergency Recirculation during Design Basis Accidents at Pressurized-Water Reactors, dated September 13, 2004
ADAMS Accession No. ML042360586, to holders of operating licenses for PWRs. In GL 200402, the NRC staff requested that these licensees perform an evaluation of the emergency core cooling system ECCS and the containment spray system CSS
