SUBJECT:
THREE MILE ISLAND NUCLEAR STATION, UNIT 1 -ACCEPTANCE OF REQUESTED LICENSING ACTION RE: LICENSE AMENDMENT REQUEST TO REVISE TECHNICAL SPECIFICATIONS TO ADOPT TSTF-523, "GENERIC LETTER 2008-01, MANAGING GAS ACCUMULATION," REVISION 2, USING THE CONSOLIDATED LINE ITEM IMPROVEMENT PROCESS (TAG NO.
MF4435)
Dear Mr. Pacilio:
By letter dated July 10, 2014, (Agencywide Documents Access and Management System Accession No. ML14191A059), Exelon Generation Company, LLC requested an amendment to Renewed Facility Operating License No. DPR-50 for Three Mile Island Nuclear Station (TMI),
Unit 1. The proposed amendment would modify technical specification (TS) requirements to address the U.S. Nuclear Regulatory Commission (NRC) generic letter (GL) 2008-01, "Managing Gas Accumulation in Emergency Core Cooling, Decay Heat Removal, and Containment Spray Systems," as described in the BWN, this was stated as Technical Specification Task Force (TSTF) Traveler TSTF-523, Revision 2, "Generic Letter 2008-01, Managing Gas Accumulation." TMI committed to submit this proposed change (if it were deemed necessary based upon evaluation) by letter dated October 14, 2008 (ADAMS Accession No. ML082880706).
The purpose of this letter is to provide the results of the NRC staff's acceptance review of this amendment request. 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 (1 0 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 it does provide technical information in sufficient detail to enable the NRC staff to complete its detailed technical review and make an independent assessment regarding the acceptability of the proposed amendment
M. Pacilio in terms of regulatory requirements and the protection of public health and safety and the environment. Given the lesser scope and depth of the acceptance review as compared to the detailed technical review, there may be instances in which issues that impact the NRC staff's ability to complete the detailed technical review are identified despite completion of an adequate acceptance review. You will be advised of any further information needed to support the NRC staff's detailed technical review by separate correspondence.
If you have any questions, please contact me at (301) 415-3100 or via e-mail at John.Lamb@ nrc.gov.
