Nuclear Regulatory Commission Attention: Document Control Desk One White Flint North 11555 Rockville Pike Rockville, MD 20852-2738 South Texas Project Units 1 and 2 Docket Nos. STN 50-498, STN 50-499 Supplement to Revised Broad Scope Risk-Informed Technical Specification Amendment Request
Reference:
Letter from David W. Rencurrel to NRC Document Control Desk dated December 28, 2006, "Revised Broad Scope Risk-Informed Technical Specification Amendment Request" (ML070040247, NOC-AE-06002036 TAC Nos. MD 2341 & MD 2342)
In the referenced correspondence, the STP Nuclear Operating Company (STPNOC) submitted a revised license amendment request for a broad scope risk-informed set of Technical Specification (TS) changes. This supplement to the license amendment request revises the license amendment request described in that application to clarify the description of the Configuration Risk Management Program in TS 6.8.3.k in response to NRC comments.
The revision to TS 6.8.3.k is an administrative clarification and does not change the requirements or application of the proposed changes to the STP TS. The Safety Evaluation and Determination of No Significant Hazards previously submitted are not affected. The revised markup to TS 6.8.3.k is attached. The other proposed TS changes previously submitted are not affected.
There are no commitments in this letter.
The proposed amendment will not have an adverse impact on the health and safety of the public.
The STP Plant Operations Review Committee has reviewed and concurred with the proposed changes.
In accordance with 10 CFR 50.91(b), the South Texas Project is providing the State of Texas with a copy of this proposed amendment.
STI: 32150665 ,"-o[

If you have any questions, please call Wayne Harrison at 361-972-7298 or me at 361-972-7454.

- 1. The revised 6.8.3.k for the Configuration Risk Management Program (CRMP) identifies changes in core damage frequency (CDF), large early release frequency (LERF), or cumulative core damage probability. In fact, NEI 06-09 assesses risk-informed completion times (RICTs) based on cumulative core damage probability (CDP) and cumulative large early release probability (LERP). Similarly, the TS bases identifies only the incremental core damage probability (ICDP) limit explicitly. The TS and bases need to correctly refer to the appropriate risk metrics used in NEI 06-09.
In addition, the staff believes the 30-day backstop should be referenced in TS 6.8.3.k.
Response: See the attached revised markup to TS 6.8.3.k. The revised Bases description was provided in a separate submittal dated May 9, 2007 (NOC-AE-07002163) in response to an NRC request for additional information. As noted in the cover letter, the changes to TS 6.8.3.k are administrative and do not affect the requirements or application of the TS. The safety evaluations and determinations of No Significant Hazards previously submitted are not affected.

Peak calculated containment internal pressure for the design basis loss of coolant accident (LOCA), Pa is 41.2 psig.
The maximum allowable containment leakage rate, La, is 0.3 percent of containment air weight per day.
Leakage rate acceptance criteria are:
- 1) Containment overall leakage rate acceptance criterion is < 1.0 La. During the first unit start-up following testing in accordance with this program, the leakage rate acceptance criteria are < 0.60 La for the combined Type B and Type C tests, and <
0.75 La as-left and < 1.0 La as-found for Type A tests.
- 2) Air lock testing acceptance criteria for the overall air lock leakage rate is < 0.05 La when tested at > Pa.
The provisions of Surveillance Requirement 4.0.2 do not apply to the test frequencies specified in the Containment Leakage Rate Testing Program.
The provisions of Surveillance Requirement 4.0.3 apply to the Containment Leakage Rate Testing Program.
