- 1) Attachment 1, Section 1.2 (Enclosure page 6) of the submittal states that, [t]he version of the Level 1 model used for input to the RI-ISI [risk-informed inservice inpection] submittal is dated February 1999. The version of the Level 2 evaluation used is dated May 2001. Page 6 of the submittal further states that the St. Lucie Unit 1 Probabilistic Safety Assessment (PSA) baseline core damage frequency (CDF) and large early release frequency (LERF) are 1.45E-5/year and 3.43E-6/year, respectively.
In a letter dated January 16, 2003, Florida Power and Light Company provided a response to the U.S. Nuclear Regulatory Commission Request for Additional Information (RAI) regarding Relief Request No. 29 for St. Lucie Unit 2. In Attachment 1, page 5 of that letter, the response to RAI question 10 provided the same text regarding St. Luce Unit 2, i.e., [t]he version of the Level 1 model used for input to the RI-ISI submittal is dated February 1999. The version of the Level 2 evaluation used is dated May 2001. Page 3 of Attachment 2 to that letter reported a CDF and LERF of 1.25E-5/year and 6.00E-6/year, respectively, for Unit 2.
Please confirm that Unit 1 and Unit 2 have different PSA models and different CDF and LERF estimates or explain why the reported estimates differ between the two submittals.
- 2) Attachment 1, Section 1.2 (Enclosure page 11) of the current submittal and the response to RAI question 10 in the January 16, 2003, letter both discuss a Combustion Engineering Owners Group peer review that was conducted during the week of May 20, 2002.
If there are two different PSA models, please explain how the peer review facts and observations reflect the two different models. Do the reported facts and observations include the review of the PSA for both Unit 1 and Unit 2?
