SUBJECT:
TRANSMITTAL OF REVISION 1 SIGNIFICANCE DETERMINATION PROCESS RISK-INFORMED INSPECTION NOTEBOOK AND INFORMATION REQUEST FOR NEXT REVISION
Dear Mr. Connelly:
On September 30, 2003, the NRC completed a two-year benchmarking activity for 71 Significance Determination Process (SDP) risk-informed inspection notebooks. All 71 notebooks were issued as revision 1, incorporating information obtained during the initial benchmarking visits. The NRC appreciates the support of each licensee in this resource intensive, first-of-a-kind effort which has greatly improved the quality of each SDP notebook to reflect the plant design-features, operational procedures and, in many cases, reduced unnecessary conservatism.
Over the course of this two year effort, insights were gained and it became apparent that these lessons learned would need to be captured in all of the notebooks, with additional effort needed for updating the notebooks that were benchmarked early in the process. It was also recognized that periodic maintenance would be required to achieve a reasonable level of accuracy as a screening tool, given changes in plant design, procedures, and revisions to the plant-specific probabilistic risk assessment (PRA) models since the original benchmarking visit.
In April of 2004, the NRC and its contractor Brookhaven National Laboratory (BNL) embarked on an SDP notebook enhancement/standardization effort for all 71 notebooks through a revision 2 process. Each revision 2 SDP notebook will contain a target set of equipment that is pre-solved in a manner similar to what was performed as part of the revision 1 benchmarking effort, in addition to capturing the lessons learned, and requesting information specific to gaps in the individual notebooks. The NRC estimates completion of the revision 2 SDP notebooks by June 30, 2005.
In order to achieve this milestone with minimal burden, the NRC requests that the plant-specific information for Callaway specified on the enclosed CD be sent to the address provided below.
The CD also contains the revision 1 SDP notebooks generated from the initial benchmarking visit. The NRC requests that your response to the plant-specific information be provided on a CD within 30 days of receipt of this request. In addition to the plant-specific requests, the NRC welcomes your comments on the revision 1 SDP notebooks.
