SUBJECT:

MCGUIRE NUCLEAR STATION, UNITS 1 AND 2-DISTRIBUTION OF REVISION 2 OF THE NRC'S SIGNIFICANCE DETERMINATION PROCESS RISK-INFORMED INSPECTION NOTEBOOK, AND ACCOMPANYING PHASE 2 PRE-SOLVED TABLES (TAC NO. MD6415)

Dear Mr. Hamilton:

In 2004, the U.S. Nuclear Regulatory Commission (NRC) staff requested information from licensees to support the Significance Determination Process Risk-Informed Inspection Notebook (notebook) enhancement/standardization effort. The NRC has completed this effort and has issued Revision 2 of the notebook for McGuire Nuclear Station, Units 1 and 2. The NRC developed the notebook to facilitate Phase 2 of the NRC inspection finding significance determination process detailed in Inspection Manual Chapter 0609, "Significance Determination Process (SDP)," Appendix A, "Determining the Significance of Reactor Inspection Findings for At-Power Situations."

SECY 99 007A, "Recommendations for Reactor Oversight Process Improvements," set 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 the notebook. The notebook 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 notebook against licensee probability risk assessments and plant configurations. The enclosed compact disk containing the above document is provided for your use to facilitate your understanding of the significance determination process in Inspection Manual Chapter 0609, "Significance Determination Process."

The enclosure transmitted herewith contains security-related information.

When separated from enclosure, this document is decontrolled.
