00-06, REGARDING TRITIUM PRODUCTION CORE AMENDMENTS (TAC NOS. MB2972 AND MB2973)
Dear Mr. Scalice:
The subject Technical Specification Amendment Request was submitted to the U.S. Nuclear Regulatory Commission (NRC) for review and approval on September 21, 2001, by the Tennessee Valley Authority (TVA). The proposed license amendments would allow SQN, Units 1 and 2, to produce tritium in their cores. The NRC staff is in the process of reviewing TVAs submittal.

Enclosure REQUEST FOR ADDITIONAL INFORMATION TRITIUM PRODUCTION CORE SEQUOYAH NUCLEAR PLANT DOCKET NOS. 50-327 and 50-328 1.
The licensees response to Question 17 regarding the loss-of-coolant accident (LOCA) peak cladding temperature (PCT)-sensitive parameters should be consistent with the wording of the question.
2.
The licensees response to Question 16 regarding the impacts of downcomer boiling is not complete. To adequately address this question, the licensee will need to provide an estimate of the impact of inadequate downcomer modeling in their Appendix K LOCA model on PCT results, and address the impact this would have on the tritium-producing burnable absorber rod temperatures. The licensee must also provide a schedule for reanalyzing their LOCA analyses once the downcomer modeling issues have been resolved.
