SUBJECT:

R.E. Ginna Nuclear Power Plant Docket No. 50-244 Reactor Vessel Surveillance Capsule "N" Results In accordance with 10 CFR 50 Appendix H, R.E. Ginna Nuclear Power Plant, LLC (Ginna LLC) hereby submits Westinghouse Report WCAP-17036-NP, "Analysis of Capsule N from the R.E. Ginna Reactor Vessel Radiation Surveillance Program," Revision 0 (Attachment 1). This report presents the analysis of test results from Capsule "N", the 5th surveillance capsule removed from the reactor vessel. The remaining capsule, "P", is currently planned to be removed shortly after accumulating a fluence equivalent to approximately 80 years of operation.

The Capsule "N" test results were used to evaluate reactor vessel material properties following 30.5 effective full power years (EFPY) of plant operation. Based on this analysis, properties of the reactor beltline materials are predicted to remain more than adequate for continued safe plant operation through the end of the renewed license period (i.e. to about 53 EFPY).

An updated PTLR incorporating the Capsule "N" test results will be submitted by February 19, 2010, per.

If you should you have any questions regarding this submittal, please contact Mr. Thomas Harding at (585) 771-5219 or Thomas.HardingJr@Constellation.com.

Very Truly Y urs, Thomas Harding 0i PL NAac&
