SUBJECT:

REQUEST FOR ADDITIONAL INFORMATION FOR THE REVIEW OF THE SHEARON HARRIS NUCLEAR POWER PLANT, UNIT 1, LICENSE RENEWAL APPLICATION

Dear Mr. Duncan:

By letter dated November 14, 2006, Carolina Power & Light Company submitted an application pursuant to 10 CFR Part 54, to renew the operating license for Shearon Harris Nuclear Power Plant, Unit 1, for review by the U.S. Nuclear Regulatory Commission (NRC or the staff). The staff is reviewing the information contained in the license renewal application and has identified, in the enclosure, areas where additional information is needed to complete the review. Further requests for additional information may be issued in the future.

Items in the enclosure were discussed with Roger Stewart, and a mutually agreeable date for the response is within 30 days from the date of this letter. If you have any questions, please contact me at 301-415-3137 or e-mail at MLH5@nrc.gov.

Sincerely,

/RA/

Request for Additional Information 2.3.4.6-2 cc w/encl: See next page

SHEARON HARRIS NUCLEAR POWER PLANT (HNP), UNIT 1 LICENSE RENEWAL APPLICATION (LRA)

REQUEST FOR ADDITIONAL INFORMATION (RAI)

RAI 2.3.4.6-2 In a letter dated September 18, 2007, the applicant responded to one of the NRC staffs request for additional information (RAI) on the classification of components (RAI 2.1.1.2-1). Specifically, the applicant states that the feedwater regulating valves in the turbine building did not meet the license renewal definition for safety-related. The applicants justification is that the regulating valves were not designed to seismic Category I requirements; therefore, they are not safety-related. (It is noted that the response to RAI 2.1.1.2-1 stated that the feedwater regulating valves are located in areas of the Turbine Building that are not designed to Seismic Category I requirements. The feedwater regulating valves are designed to ASME Section III, Class 3, Seismic Category I requirements.) However, the applicants Final Safety Analysis Report (FSAR) Section 10.4.7 states that these components are designed to seismic Category I criteria and these components have a specific safety function, as defined in Section 15.1.5, to provide redundant feedwater isolation.

The License Renewal Application (LRA), Section 2.3.4.6, Feedwater System, states, The system serves no safety function, with the exception of containment isolation integrity, and is, therefore, generally classified as non-safety related. The portion of the system classified as safety-related is the portion from the feedwater header check valves to the Steam Generators.

As stated above, the FSAR states that these regulating valves do provide an important safety function. Section 2.3.4.6 of the LRA contradicts the FSAR in stating that this system does not provide any other safety function besides containment integrity.

Based upon the available information, the NRC staff understands that the information in the current licensing basis substantiates that the feedwater regulating valves do provide a safety-related function, (i.e., mitigates the consequences of an accident in accordance with 10 CFR 54.4(a)(1)(iii)). Accordingly, the applicant should either include the feedwater regulating valves in the scope of license renewal and subject then to aging management based upon criterion 10 CFR 54.4(a)(1) or provide an adequate justification for exempting the valves. In addition, the applicant should provide an evaluation of other feedwater components, (e.g.,

backup isolation valves, and feedwater pump discharge valves) included in this FSAR description with the intended function of providing redundant feedwater isolation to determine whether they are included in the scope of license renewal or provide a justification for exempting the components. Finally, pursuant to 10 CFR 54.21(a), the applicant should identify components surrounding the above-mentioned 10 CFR 54.4(a)(1) components that would fall within the scope of license renewal pursuant to 10 CFR 54.4(a)(2) and subject to an aging management review.
