Subject:

Crystal River' Unit 3.

Docket No. 50-302 Operating' License No. DPR-72 Emergency Diesel Generator Loading

Dear! Sir:

The: purpose of this-letter is to follow up on and document a discussion in ourl meeting-on January 16, 1990. The. subject of that discussion was.'short b -term loads on the emergency diesel generators,'specifically, motor operated valves.-

k; UThe' electrical' loads associated with motor operated valves are ng_t; included-1 in q the overall' diesel generator . loading.

'This-is because the loads'are-ienergized .only 'for a short duration,- usually less than .one- minute. .

-~ Additionally, these -_are small = loads, less than150 kw: total', - and - do not

, ?significantly affect the overall diesel' loading.o

These loads arg included in the transient. calculations donetto determine the-

_ voltage and= frequency response of the machines to the block loading ' sequence.

,This assures that allowable voltage and> frequency limits will be-maintained.

4This1 treatment (Attachment 2,-Diesel Generator Loading Evaluation, page III-

1) . of momentary loads. Lis consistent with the description- 'in Technical

. Specification Change-Request No. 157, Revision 1,-dated November 25, 1987.:

.Should there be any questions, please contact-this office.
