ME9819)
Dear Mr. Pacilio:
By letter dated October 18, 2012 (Agencywide Documents Access and Management System Accession No. ML 12292A585), Exelon Generation Company, LLC (Exelon, the licensee) submitted a relief request, VR-01, associated with the fifth inservice testing interval at Three Mile Island Nuclear Station, Unit 1. The request proposes alternative testing, as compared to the requirements of the applicable American Society of Mechanical Engineers Code for Operation and Maintenance of Nuclear Power Plants, for the Pressurizer Pilot Operated Relief Valve. The Nuclear Regulatory Commission staff has been reviewing the submittal and has determined that additional information is needed to complete its review. The specific questions are found in the enclosed request for additional information (RAI). The questions were sent via electronic transmission on February 13, 2013, to Mr. Thomas Loomis, of your staff. The draft questions were sent to ensure that they were understandable, the regulatory basis was clear, and to determine if the information was previously docketed. The draft questions were discussed in a teleconference with your staff on February 20, 2013. It was agreed that a response to this RAI would be submitted by March 29, 2013. Please contact me at 301-415-2833, if you have any questions.

The request proposes alternative testing, as compared to the requirements of the applicable American Society of Mechanical Engineers (ASME) Code for Operation and Maintenance of Nuclear Power Plants (OM Code), for the Pressurizer Pilot Operated Relief Valve (PORV). The U.S. Nuclear Regulatory Commission staff has been reviewing the submittal and has determined that additional information is needed to complete its review. The PORV, 1-RC-RV-2, is categorized as a BIC valve in the referenced request. In addition to the requirements of the OM Code, ISTC-3310 and ISTC-3510 (for which relief is being requested), are any other ASME OM Code ISTC or Mandatory Appendix I test requirements applicable to this valve? Please provide any specific ASME OM Code test requirements for this valve type, but don't provide general test requirements from the OM Code. Is the Pressurizer PORV block valve included in the TMI-1 1ST program? If not, please provide the basis for not including this valve in the program. Enclosure February 25, 2013 Mr. Michael J.
