Acceptance Review Results of Relief Request I3R-06 for Clinton Power Station, Unit No. 1 (TAC ME4238)

Mr. Mathews, By letter dated July 13, 2010, Exelon Generation Company, LLC (the licensee) submitted relief request (RR) No. I3R-06 related to use of Code Case N-513-2 for Clinton Power Station (CPS),

Unit No. 1 (ADAMS Accession No. ML101940408). The proposed RR would allow the use of ASME Code Case N-513-2 as an acceptable method for evaluating the structural integrity of flaws identified in moderate energy piping for the 3rd Inservice Inspection Interval at CPS. The purpose of this message is to provide the results of the Nuclear Regulatory Commission (NRC) staff's acceptance review of this submittal. The acceptance review was performed to determine if there is sufficient technical information in scope and depth to allow the NRC staff to complete its detailed technical review. The acceptance review was also intended to identify whether the applications have any readily apparent information insufficiencies in its characterization of the regulatory requirements or the licensing basis of the plant.

Pursuant to Sections 50.55a(a)(3)(i) and 50.55a(a)(3)(ii) of Title 10 of the Code of Federal Regulations (10 CFR), the applicant shall demonstrate that the proposed alternatives would provide an acceptable level of quality and safety, or that compliance with the specified requirements of Section 50.55a would result in hardship or unusual difficulty without a compensating increase in the level of quality or safety.

The NRC staff has reviewed your application and has concluded that it provides technical information in sufficient detail to enable the NRC staff to proceed with its detailed technical review and make an independent assessment regarding the acceptability of the proposed amendments in terms of regulatory requirements and the protection of public health and safety and the environment. If additional information is needed for the NRC staff to complete its technical review, you will be advised by separate correspondence.

In accordance with our process as described in LIC-109, "Acceptance Review Procedures," I am placing a copy of this email in ADAMS as a publicly-available, official agency record.

Sincerely, Nicholas DiFrancesco Project Manager Nuclear Regulatory Commission Division of Operating Reactor Licensing nicholas.difrancesco@nrc.gov Tel: (301) 415-1115 Fax: (301) 415-1222 E-mail Properties
