Dear Mr. Shea:

In a letter dated December 31, 2014, (Agencywide Documents Access and Management System (ADAMS)

Accession Nos. ML14365A207), Tennessee Valley Authority (TVA, the licensee) submitted a request for alternative PR-07 to the U.S. Nuclear Regulatory Commission (NRC). TVA proposed alternatives to certain inservice testing (IST) requirements of the American Society of Mechanical Engineers Code for Operation and Maintenance of Nuclear Power Plants (ASME OM Code), for the IST program at Sequoyah Nuclear Plant (SQN) Units 1 and 2 for the remainder of third and entire fourth 10-year IST programs interval. Specifically, pursuant to Title 10 of the Code of Federal Regulations (10 CFR) 50.55a(a)(3)(i), TVA requested to use the proposed alternatives in PR-07on the basis that the alternatives provide an acceptable level of quality and safety.

The NRC staff is reviewing your submittal and has determined that additional information is required to complete the review. The specific information requested is shown below. The proposed questions were discussed by telephone with your staff on June 22, 2015. Your staff confirmed that these questions did not include proprietary or security-related information and agreed to provide a response in 30 days from this request for additional information (RAJ).

Please note that if you do not respond to this letter by the agreed-upon date or provide an acceptable alternate date in writing, we may deny your application for amendment under the provisions of Title 10 of the Code of Federal Regulations, Section 2.108. Please also note that review efforts on this task are continuing and additional RAls may be forthcoming.
