DPR-58 and DPR-74 REGULATORY GUIDE 1.97 ACCUMULATOR VOLUME AND PRESSURE U. S. Nuclear Regulatory Commission Document Control Desk Washington, D.C. 20555 Attn: W. T. Russell April 29, 1994.

Dear Mr. Russell:

This letter is in regard to the Safety Evaluation (SE) performed on relaxing the qualification requirements of accumulator level and pressure monitoring instrumentation, from Regulatory Guide 1.97 Category 2 to Category 3, prepared and distributed by your staff in a letter to Indiana Michigan Power Company, dated November 17, 1993. That letter, further, requested that you be notified of the actions we plan to take and our schedule for implementation.

At this time our intended actions, which are completed with this submittal, are to remove these instruments from our environmental qualification (EQ) program and to change the qualification requirements of these instruments from Category 2 to Category 3 on the table that was provided to you as an attachment to our letter AEP:NRC:0773AB, dated October 5, 1988. A marked up copy of that table, margin-marked for quick reference, is provided as an attachment to this letter. As to future action(s), while these instruments will be maintained on their current surveillance/calibration frequency, they will not be changed out unless they fail or become a high maintenance problem, at which time we would most likely opt to substitute instruments that meet

'0 Regulatory Guide 1 97 Category 3 qualification requirements.
