THREE MILE ISLAND NUCLEAR STATION, UNIT 1 - ACCEPTANCE OF REQUESTED LICENSING ACTION RE: ADOPTION OF TSTF-522 (TAC NO. MF4110)

Dear Ms. Wendy Croft:

By letter dated May 7, 2014, (Agencywide Document Access and Management System Accession No. ML14127A424) Exelon Generation Company, LLC submitted a license amendment request for Three Mile Island Nuclear Station Unit 1 (TMI-1). The proposed amendment would modify TMI-1 Technical Specification 4.12, Air Treatment System, by replacing an existing Surveillance Requirement to operate ventilation systems with charcoal filters for a 10-hour period every 31 days with a requirement to operate the systems for greater than or equal to 15 continuous minutes every 31 days in accordance with Technical Specification Task Force (TSTF) Traveler TSTF-522, Revision 0, "Revise Ventilation System Surveillance Requirements to Operate for 10 hours1.157407e-4 days <br />0.00278 hours <br />1.653439e-5 weeks <br />3.805e-6 months <br /> per Month."

The purpose of this e-mail is to provide the results of the U.S. Nuclear Regulatory Commission (NRC) staff's acceptance review of this license 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 (10 CFR), an amendment to the license (including the TS) 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 license amendment request 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 301-415-4090.
