Docket Nos. 5()..247*LR &; 50-286--LR Report of Dr. Joram Hopeofeld In support oflUC.-TC- IB I I I I

• As a result of these deficiencies, Entergy's calculations have a wide margin of error and have likely underestimated the CUFco values. As many of the values derived by Entergy'5 new evaluation are very close to unlty, the regulatory threshold, it is biibly liI<ely that if Entergy had accurately considered 011 relevant factors, many of the CUF_

values would, in actuality, exceed 1.0;

• Entcrgy has improperly failed to confirm that the components evaluated represent the most limiting locations providing a hounding analysis, and failed to expand the scope of oomponents to be subject to a CUFon analysis accordingly;

• In light of the insufficiency ofEntergy' $ CUFf:JI analyses, Entergy bas otb~ failed to provide any details concerning the inspection. monitoring, repair, and rq>lacement to ensure that the degradation effects of metal fatigue would he sufficiently handled.

Accordingly, Entcrgy bas failed to demonstrate that the aging effects of metal futigue will he adequately managed for the period of ""tended operation, and has, thus, failed to comply with 10 C.F.R. § 54.21(c) or regulatory guidance, including the GALL Report.
