As discussed in a telephone conversation on August 15, 1975 between hfr. C. Mangan and Mr. W. Norwicke of Niagara Mohawk Power Corporation and Mr. J. Guibert and her. F. Clem)nson of the U. S. Nuclear Regulatory Commission, we require information concerning potential operational limitations of the onsite standby emergency diesel engines for Nine Mile Point Unit 1.

In this regard, your rosponse to the following is requested:

(a)

For each modol diesel engine and its associated subsystems, describe and discuss any known lim~tations on continuous operation for considerable lengths of time (at least thirty days) at rated speed and for all power output levels.

(b)

Identify the following:

(1) the components or subassemblies that impose the limitations.

(2) the most adverse consequence should the limitations be disregarded.

(3) the possible design modifications 'and/or alterations which you believe will permit the diesel engine to overcomo any limitations and to meet its intended function.

(c)

With these limitations discussed above, provide the power output versus operating time in either tabular or graphical form over the entire poser output ronde of the diesel units (i.e.,

100 percent of rated power to zero power output).
