SUBJECT:
R.E. Ginna Nuclear Power Plant Docket No. 50-244 Change in Submittal Date for the Augmented Reactor Vessel Internals Inspection Program Document
REFERENCE:
License Renewal Safety Evaluation Report for the R.E. Ginna Nuclear Power Plant, date March 3, 2004 As part of the R.E. Ginna Nuclear Power Plant (Ginna) license renewal efforts, a commitment was made related to the Ginna Reactor Vessel Internals Aging Management Program. The commitment includes a plan to develop an aging management program for the reactor internals that would be based oti the industry EPRL/MRP efforts to provide a standardized pressurized water reactor (PWR) inspection guideline for reactor internals.
The commitment was to submit an internals Aging Management and Inspection Program for Ginna to the NRC by September 2007. The EPRIIMRP program is intended to provide an industry-wide, consistent approach that would be based on the most recent industry research and modeling techniques associated with the behavior of the internals materials following exposure to the neutron fields associated with the reactor core.
A standard approach on the internals program is intended to eliminate duplication and inefficiencies of each plant taking a different approach in determining the most severe or limiting degradation conditions for each component. It is also intended to reduce the amount of review time required by the NRC if all PWRs follow a standard inspection and evaluation guideline.
The current schedule for the EPRI/MRP draft of the PWR industry internals aging management guideline is December 2007. A detailed and lengthy industry and NRC review of the draft guideline is expected to follow. Therefore, Ginna is changing the commitment for the submittal of the Ginna specific Internals Aging Management Program to February 2009.
