ONITED STATES NUCLEAR REGULATORY COMMISSION WASHINGTON, D,C. 2DSS$ 40M December 29, 1998 Mr. Robert P. Powers, Senior Vice President Indiana Michigan Power Company Nuclear Generation Group 500 Circle Drive Buchanan, Ml 49107
SUBJECT:
DONALDC. COOK NUCLEAR PLANT, UNITS 1 AND 2 - EVALUATIONOF THF THIRD 10-YEAR INTERVALINSERVICE INSPECTION PROGRAM PLAN AND ASSOCIATED REQUESTS FOR RELIEF (TAC NOS. M94871 AND M94872)
Dear Mr. Powers:
By letter dated January 25, 1996, Indiana Michigan Power Company (the licensee) submitted the third 10-year program for the inservice inspection (ISI) program for the D.C. Cook Nuclear Plant. The program contained requests for relief from the requirements of the applicable American Society of Mechanical Engineers (ASME) Code Section XI. In addition, the licensee requested permission to use alternatives to the Code. Additional information was provided by the licensee in subsequent letters dated September 10, 1996, November 7, 1996, and July 8, 1998. The staff has evaluated the information provided by the licensee regarding the relief requested and proposed alternatives.
The staffs Safety Evaluation (SE) providing the specific details is enclosed.
Based on the staffs evaluation, it was determined that for Relief Request No. 1 regarding the reactor pressure vessel (RPV) shell welds, Relief Request No. 4, Relief Request No. 5, and Relief Request No. 6, the requirements of the Code are impractical and the reliefs are granted in the third 10-year interval pursuant to 10 CFR 50.55a(g)(6)(i). The relief granted is authorized by law and willnot endanger life or property, or the common defense and security, and is otherwise in the public interest given due consideration to the burden upon the licensee that could result if the requirements were imposed on the facilities.
In addition, based on the staffs evaluation, it was determined that Relief Request No. 1 concerning RPV nozzle-to-vessel welds, Relief Request No. 2, and Relief Request No. 3 are denied because the licensee has not provided adequate information to demonstrate that relief can be granted or an alternative authorized.
For Proposed Alternatives N-524 and N491-1, the staff finds that the alternatives are authorized pursuant to 10 CFR 50.55a(a)(3)(i) in that the licensee's proposed alternatives provide an acceptable level of quality and safety. The proposed alternatives are authorized for the current interval or such time as the Code Cases are published in Regulatory Guide 1.147.
At that time, ifthe licensee intends to continue to implement Code Case N-524, the licensee should followall provisions of the Code Case with the limitations issued in Regulatory Guide 1.147, ifany.
The staff evaluated proposed Alternatives N-509 and N-521 and found that they did not provide an acceptable level of quality and safety. Therefore, the proposed alternatives were denied.
