SUBJECT:

DONALD C. COOK NUCLEAR PLANT, UNITS 1 AND 2 - REQUEST FOR ADDITIONAL INFORMATION, PROPOSED ALTERNATIVES TO THE REQUIREMENTS OF SECTION XI OF THE AMERICAN SOCIETY OF MECHNICAL ENGINEERS CODE (TAC NOS. MB3551 AND MB3552)

Dear Mr. Bakken:

By letter dated December 6, 2001, Indiana Michigan Power Company, pursuant to 10 CFR 50.55a(a)(3)(i) and 10 CFR 50.55a(a)(3)(ii) submitted two alternatives to the requirements of Section XI of the American Society of Mechanical Engineers Boiler and Pressure Vessel Code (ASME Code).

The Nuclear Regulatory Commission (NRC) staff has reviewed your request and concluded that it does not provide technical information in sufficient detail to enable the staff to make an independent assessment regarding the acceptability of the proposal in terms of regulatory requirements and the protection of public health and safety.

Draft questions were discussed with Mr. J. Waters, et al., of your staff on February 20, 2002.

A mutually agreeable target date of April 12, 2002, for your response was established. The NRC staff will continue review of your proposed alternatives when your response to the enclosed questions is received.

If circumstances result in the need to revise the target date, please contact me at (301) 415-1345 at the earliest opportunity.

Sincerely,

/RA/

John F. Stang, Senior Project Manager, Section 1 Project Directorate III Division of Licensing Project Management Office of Nuclear Reactor Regulation Docket Nos. 50-315 and 50-316
