On September 29, 2006 R.E. Ginna Nuclear Power Plant, LLC (Ginna LLC) submitted Reference 1 in accordance with the provisions of 10 CFR 50.90. On October 16,.2006 Ginna's NRC Licensing Project Manager contacted Ginna Licensing by telephone indicating that sections 1.3.4 and 1.3.5 appear to be missing from Attachment (2) to Reference 1 (Risk Insights). In performing an additional review of the document, Ginna determined that there was also a minor error in Section 1.1.10.1 of Attachment (2). Attachment (1) to this letter contains those missing sections and corrections and should be considered an Addendum to Reference 1.

Corrected Paragraph:
1.1.10.1 Model Peer Review In May 2002, the Westinghouse Owners Group performed a Peer Review of the GPSA Revision 4.1. The peer review final report was issued in December, 2002 (R. E. Ginna Station PSA Peer Review Report, Westinghouse Electric Co., December 2002; PSA Peer Review Certification Process Guidance, SAE/RRA/101(98)-A, Westinghouse Energy Systems, 1998). The GPSA received a grade of full 3 for one of the technical elements, and a grade of 3 with contingencies for all other technical elements. The contingencies were due to outstanding facts and observations (F&O's) identified during the peer review. Since the completion of the review, the majority of the peer review F&O's (all six A-level and thirty four of thirty six B-level) have been addressed. A list of all A and B level F&O's, and their resolution, is provided below. The two remaining peer review comments that are not fully addressed (F&O's AS-13 and DE-01) are evaluated to ensure that they do not effect the ability of the model to estimate the risk impact of the proposed change, as discussed in the resolution of each of these items.
The following is a list of Level A and B observations and resolutions. The model revision in which the observation was resolved is shown at the end of the resolution:
Omitted Sections:
1.3.4 On-line Risk Assessment - Level 2 The Ginna on-line risk assessment process discussed in section 1.3.3.2, above, directly assesses Level 2 risk by using the LERF metric.
1.3.5 On-line Risk Assessment - External Events The Ginna on-line risk assessment process discussed in section 1.3.3.2, above, directly assesses some external events. Fire events are directly modeled in the quantitative risk assessment. For high wind events, the only impact modeled in the quantitative risk assessment is an increase in the frequency of a loss of offsite power. Other external events (e.g., seismic, transportation events, etc.) are not addressed in the on-line risk assessment.
