Turkey Point EPU - Nuclear Performance and Code Review (SNPB) Request for Additional Information - Round 2
- Steve, Below are follow-up requests for additional information (RAIs) regarding the Turkey Point Extended Power Uprate license amendment request. On June 10, 2011, the Nuclear Regulatory Commission (NRC) staff and Florida Power & Light Company (FPL) discussed draft RAIs to gain a common understanding of the questions.
The below RAIs reflect the questions discussed during the June 10, 2011, call. FPL agreed upon providing its responses within 30 days of the date of this email. If you have any questions, feel free to contact me.
SNPB-2.1 The response to RAI SNPB-1.1 indicated that the nuclear design code package used in the analysis relies on the ENDF/B-VI cross section library from the early 1990s rather than the current ENDF/B-VII library that was updated 2006. Provide justification that the use of the ENDF/B-VI library cross section data provides sufficiently accurate results (e.g., through comparison to results generated from current cross section data).
SNPB-2.2 The response to RAI SNPB-1.1 discussed experimental benchmarking of the PHOENIX-P/ANC code package, referencing benchmarking discussed in WCAP-11596-P-A and stating that similar benchmarking was performed in 1997 to support implementation of the ENDF/B-VI cross section library data. However, it appeared that the experimental data referenced in WCAP-11596-P-A did not encompass fuel enrichments up to 5 wt%; furthermore, details of the 1997 benchmarking effort were not discussed in the RAI response. Therefore, provide a comprehensive summary of the experimental and computational efforts to benchmark the PHOENIX-P/ANC code package for performing analysis with uranium oxide fuel enriched to 5 wt% (or greater) uranium-235. If experimental benchmarking at approximately 5 wt%
enrichment has not been performed, identify the upper enrichment limits that have been benchmarked and provide alternate justification that the PHOENIX-P/ANC code package provides sufficiently accurate results at 5 wt%.
