SUBJECT:

NRC INSPECTION REPORT NO. 50-410/9344

This letter refers to the safety inspection of engineering and technical support activity related

to the Niagara Mohawk Power Corporation {NMPC) Nine Mile Point Station Unit No. 2

(NMPU2) conducted by Mr. A. Lohmeier of this office during the period

March 22-26, 1993, in Lycoming, New York. At the conclusion of the inspection, his

findings were discussed with Mr. McCormick, Jr., and members of the NMPU2 engineering

and licensing staff.

The scope of this inspection included review of your engineering and technical support

effectiveness in monitoring transient operation of primary components and piping.

As the

plant increases in age, it is important to have identified those component and piping

transients approaching the numbers of cycles for which they have been designed.

Effective

performance in these areas by your engineering and technical support personnel is important

to the safe operation of the plant and protection of public health and safety.

Based on the results of this inspection, your engineering and technical support staff

effectively addressed

these areas, properly recording and evaluating the effect of plant

operating cycles on the remaining life of primary components.

Your engineering staff has

identified the fact that the number of start up and shutdown cycles to date has been at a rate

greater than that anticipated for the design of the components

and piping under fatigue

loading.

An action plan is under consideration to ameliorate the potential problem of

primary components

and piping operating beyond the design basis for fatigue strength before

the 40-year anticipated plant lifetime. Your support of these considerations willbe helpful.
