D.C. Cook Nuclear Plant Unit Nos. 1 & 2 - Request for Additional Information related to LAR to address NSAL-15-1 (EPID L-2018-LLA-0246)

By letter dated February 26, 2019 (Agencywide Documents Access and Management System (ADAMS)

Accession No. ML19060A060), Indiana Michigan Power Company (I&M), the licensee for Donald C. Cook Nuclear Plants, Units 1 and 2 (CNP), has requested an amendment to CNP Technical Specifications (TS). The proposed change will expand criteria within TS 3.2.1 Surveillance Requirements (SRs) which will apply an appropriate penalty factor to measured transient FQ(Z). The proposed modification of the SR was to address a deficiency identified in the Westinghouse Nuclear Safety Advisory Letter (NSAL) NSAL-15-1, Rev.

0.

The U.S. Nuclear Regulatory Commission staff has reviewed the submittal and determined that additional information is required in order to complete the review. Therefore, included in this e-mail is a DRAFT requested for additional information (RAI). If I&M would like clarification on the included DRAFT RAI contact me to set up a teleconference. If no clarification is required this DRAFT RAI will be considered a final RAI and the NRC staff will expect a response within 30 days of this message.

Sincerely, Robert F. Kuntz, Senior Project Manager Plant Licensing Branch III Division of Operating Reactor Licensing Office of Nuclear Reactor Regulation REQUEST FOR ADDITIONAL INFORMATION (RAI)

LICENSE AMENDMENT REQUEST TO ADDRESS ISSUES IDENTIFIED IN WESTINGHOUSE DOCUMENT NSAL-15-1 DONALD C. COOK NUCLEAR PLANT, UNIT 1 AND UNIT 2 (EPID: L-2019-LLA-0039)

Regulatory Basis:

10 CFR 50.34, "Contents of applications; technical information," requires that safety analysis reports analyze the design and performance of structures, systems, and components provided for the prevention of accidents and the mitigation of the consequences of accidents. As part of the core reload process, licensees perform reload safety evaluations to ensure that their safety analyses remain bounding for the design cycle. To confirm that the analyses remain bounding, they confirm that the inputs to the safety analyses are conservative with respect to the current design cycle. These inputs are checked using analytical models, and if key safety analysis parameters are not bounded, further analysis of the affected transients or accidents is performed to ensure that the applicable acceptance criteria are satisfied.

In 10 CFR 50.36, Technical specifications, the NRC established its regulatory requirements related to the content of TSs. As discussed in 10 CFR 50.36(c)(3), surveillance requirements (SRs) are requirements relating to test, calibration, or inspection to assure that the necessary quality of systems and components is maintained, that facility operation will be within safety limits, and that the LCOs will be met.

1

FQ is an input used in safety analyses and is a parameter that is subject to the surveillance requirements of 10 CFR 50.36.

SRXB RAI - 1 a) Does the fuel thermal conductivity degradation (TCD) issue, as described in NRC Information Notice 2012-21, impact measured transient FQ(Z)? If so, b) Confirm that the TCD issue was addressed for CNP. Otherwise, explain how fuel TCD is accounted for.
