Request for Additional Information - Relief Request 2C3-1 (TAC No. MF5780)

Tim, By letter dated February 24, 2015 (Accession Number ML15065A042), Luminant Generation Company LLC (Luminant, the licensee) requested relief from the requirements of the American Society of Mechanical Engineers Boiler and Pressure Vessel Code (ASME Code). The relief request 2C3-1 pertains to the system leakage test of the reactor pressure vessel (RPV) head flange seal leak-off lines piping at the Comanche Peak Nuclear Power Plant (CPNPP), Unit 2.

The U.S. Nuclear Regulatory Commission (NRC) staff needs the following additional information to complete its review:

By Federal Register Notice 79 FR 65776, dated November 5, 2014, which became effective on December 5, 2014, the paragraphs headings in Title 10 of the Code of Federal Regulations (10 CFR),

Paragraph 50.55a were revised. Accordingly, relief requests that had been previously covered by 10 CFR 50.55a(a)(3)(i) are now covered under the equivalent 10 CFR 50.55a(z)(1) and relief requests that had been previously covered by 10 CFR 50.55a(a)(3)(ii) are now covered under the equivalent 10 CFR 50.55a(z)(2).

The NRC staff notes that the licensee submitted its request pursuant to 10 CFR 50.55a(h)(3)(z)(1). It appears that the licensee made a typographical error when cited the regulation, because paragraph (h)(3)(z)(1) does not exist in 10 CFR 50.55a. Please revise the relief request to cite the correct regulation (i.e., pursuant to 10 CFR 50.55a(z)(2) under hardship). If not, please provide justification.

Draft Request for Additional Information (RAI) was transmitted on May 4, 2015. Jack Hicks of Luminant informed us on May 4, 2015 that a clarification call is not needed. The licensee agreed to respond to the RAI within 30 days from the date of this e-mail.

Thanks.
