By Reference 1, STP Nuclear Operating Company (STPNOC) submitted a request for exemption from the regulations and a risk-informed approach to closure for Generic Safety Issue (GSI)-191, "Assessment of Debris Accumulation on Pressurized-Water Reactor Sump Performance," for approval by the U.S. Nuclear Regulatory Commission (NRC) based on criteria in Regulatory Guide (RG) 1.174. The application is intended for the South Texas Project (STP)

Units 1 and 2 to be the pilot for other licensees pursuing a risk-informed approach to resolving GSI-191. By Reference 2, the NRC staff identified supplemental information needed for acceptance of Reference 1. The purpose of this letter is to provide a schedule for submittal of the information responsive to the staff's requests.

As discussed with the NRC staff on April 2, 2013, STPNOC will provide the information listed in Reference 2 related to the exemption request and the RG 1.174 application, and will submit a license amendment request (LAR) for NRC review and approval of the proposed changes to the STP Units 1 and 2 licensing basis. As an alternative to the requested date provided in Reference 2, STPNOC requests a public meeting with the NRC to discuss the planned responses, to be held on or about the third week in May 2013. Following the public meeting and not later than June 20, 2013, STPNOC will provide the supplemental information necessary to enable the staff to complete its acceptance review.
