NRC ISSUES SUPPLEMENTAL SAFETY EVALUATION FOR
OYSTER CREEK LICENSE RENEWAL
Printable Version

The Nuclear Regulatory Commission has issued a supplemental safety evaluation report for the license renewal application of the Oyster Creek Nuclear Generating Station in Toms River, N.J.

The supplement clarifies commitments agreed to by AmerGen Energy Co., the plant’s operator, as part of the aging management program for the reactor’s drywell shell. It also documents the NRC staff’s evaluation of AmerGen’s reanalysis of the effects of fatigue on reactor recirculation outlet nozzles. The NRC asked AmerGen to conduct a new analysis when the staff determined that AmerGen’s original calculations used only one of six stress components typically used. The staff’s evaluation determined that the original analysis was, in fact, considerably more conservative than the confirmatory analysis. Therefore, the original results were acceptable.

The supplemental safety evaluation report does not identify new open items. There are no new license conditions resulting from this supplement.

�� The supplement will be available on the NRC’s Web site on the Oyster Creek license renewal page, http://www.nrc.gov/reactors/operating/licensing/renewal/applications/oystercreek.html. Information about the license renewal process is available at http://www.nrc.gov/reactors/operating/licensing/renewal.html.
