NUCLEAR REGULATORY COMMISSION WASHINGTON, D.C. 20555-0001 October 19, 2007 Mr. Darin Benyak Director - Licensing Mid-West Exelon Generation Compariy, LLC 4300 Winfield Road Warrenville, IL 60555
SUBJECT:
DISTRIBUTION OF REVISION 2 OF THE NRC'S SIGNIFICANCE DETERMINATION PROCESS RISK-INFORMED INSPECTION NOTEBOOKS, AND ACCOMPANYING PHASE 2 PRE-SOLVED TABLES (MD6415)
Dear Mr. Benyak:
In 2004, the U.S. Nuclear Regulatory Commission (NRC) requested information from licensees to support the Significance Determination Process (SDP) Risk-Informed Inspection Notebook (notebook) enhancement/standardization effort. The NRC has completed this effort and has issued revision 2 of the notebook for Braidwood Station, Units 1 and 2 (Braidwood),
Byron Station, Unit Nos. 1-and 2 (Byron), Clinton Power Station, Unit No. 1 (Clinton), Dresden Nuclear Power Station, Units 2 and 3 (DNPS), LaSalle County Station, Units 1 and 2 (LSCS),
and Quad Cities Nuclear Power Station, Units 1 and 2 (QCNPS). The NRC developed these notebooks to facilitate Phase 2 of the NRC inspection finding significance determination process detailed in Inspection Manual Chapter 0609, "Significance Determination Process,"
Appendix A, "Determining the Significance of Reactor Inspection Findings for At-Power Situations." SECY-99-007A, "Recommendations for Reactor Oversight Process Improvements," sets forth this process and additional details are included in the NRC Inspection Manual Chapter 0308, "Reactor Oversight Process Basis Document." NRC inspectors and risk analysts, who have extensive understanding of plant-specific design features and operation, are expected to use these notebooks. The notebooks will be updated on a case by case basis as needed to reflect changes to the facilities.
Revision 2 of the notebooks is accompanied by the Site Specific Pre-Solved Spreadsheet (the Spreadsheet). The NRC added the Spreadsheet to help reduce the time it takes to process inspection findings. The NRC benchmarked the notebooks against licensee Prob~abilistic Risk Assessments and plant configurations. The enclosed compact disks containing the above documents are provided for your use to facilitate your understanding of the SDP in Inspection Manual Chapter 0609.
The enclosures transmitted herewith contain Security-Related Information.
When separated from enclosures, this document is decontrolled.
