SUBJECT:
SHEARON HARRIS NUCLEAR POWER PLANT, UNIT 1 - SUPPLEMENTAL INFORMATION NEEDED FOR ACCEPTANCE OF REQUESTED LICENSING ACTION REGARDING THE LICENSE AMENDMENT REQUEST TO REVISE TECHNICAL SPECIFICATION TABLE 3.3-4, "DEGRADED VOLTAGE TIME DELAY VALUES" (TAC NO. MF0308)
Dear Mr. Hamrick:
By letter dated November 29, 2012 (Agencywide Documents Access and Management System Accession No. ML123350104), Carolina Power and Light Company (the licensee), doing business as Duke Energy, submitted a license amendment request (LAR) for Shearon Harris Nuclear Power Plant, Unit 1. The proposed amendment request would revise Technical Specification (TS) Table 3.3-4 associated with a 6.9kV Emergency Bus Secondary Undervoltage time delay values to resolve a nonconservative TS. The purpose of this letter is to provide the results of the U.S. Nuclear Regulatory Commission (NRC) staff's acceptance review of this LAR. 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 is also intended to identify whether the application has any readily apparent information insufficiencies in its characterization of the regulatory requirements or the licensing basis of the plant.
Consistent with Section 50.90 of Title 10 of the Code of Federal Regulations (10 CFR), an amendment to the license (including the TSs) must fully describe the changes requested, and following as far as applicable, the form prescribed for original applications. Section 50.34 of 10 CFR addresses the content of technical information required. This section stipulates that the submittal address the design and operating characteristics, unusual or novel design features, and principal safety considerations.
The NRC staff has reviewed your application and concluded that the information delineated in the enclosure to this letter is necessary to enable the staff to make an independent assessment regarding the acceptability of the proposed amendment/relief request in terms of regulatory requirements and the protection of public health and safety and the environment.
Mr. Hamrick
- 2 In order to make the application complete, the NRC staff requests that the licensee supplement the application to address the information requested in the/enclosure by January 3, 2013. This will enable the NRC staff to begin its detailed technical review. If the information responsive to the NRC staff's request is not received by the above date, the application will not be accepted for review pursuant to 10 CFR 2.101, and the NRC will cease its review activities associated with the application. If the application is subsequently accepted for review, you will be advised of any further information needed to support the staff's detailed technical review by separate correspondence.
The information requested and associated time frame in this letter was discussed with Mr. John Caves of your staff on December 13,2012.
If you have any questions, please contact me at (301) 415-3302 or via e-mail at Araceli. Billoch@nrc.gov.
Sincerely, Araceli T. Billoch Col6n, Project Manager Plant Licensing Branch 11-2 Division of Operating Reactor Licensing Office of Nuclear Reactor Regulation Docket No. 50-400

SUPPLEMENTAL INFORMATION NEEDED LICENSE AMENDMENT REQUEST TO REVISE TECHNICAL SPECIFICATION TABLE 3.3-4 "DEGRADED VOLTAGE TIME DELAY VALUES" CAROLINA POWER & LIGHT SHEARON HARRIS NUCLEAR POWER PLANT, UNIT 1 DOCKET NO. 50-400 By letter dated November 29, 2012 (Agencywide Documents Access and Management System Accession No. ML123350104), Carolina Power and Ught Company (the licensee), doing business as Duke Energy, submitted a license amendment request (LAR) for Shearon Harris Nuclear Power Plant, Unit 1. The proposed amendment request would revise Technical Specification (TS) Table 3.3-4 associated with a 6.9kV emergency bus secondary undervoltage time delay values to resolve a nonconservative TS. The purpose of this letter is to provide the results of the U.S. Nuclear Regulatory Commission (NRC) staff's acceptance review of this license amendment request. The NRC staff has determined that the LAR is non-acceptable with opportunity to supplement. The reason for the nonacceptance is that the application is not complete.
The following information is needed for the acceptance review:
- 1.
Provide the calculations to support the justification of the revision being made to the degraded voltage time delay relays.
- 2.
Clarify how the proposed degraded voltage time delay relays are consistent with the current Loss-of-Coolant Accident (LOCA) analysis and why the licensee intends to revise the LOCA analysis for implementation during the next refuling outage.
