Crystal River Unit #3 Docket No. 50-302
Dear Mr. Stol:
On October 4,1976 we received your October 1,1976 Request for Additional Infomation concerning equipment failures during a degraded grid voltage condition.
Specifically, you requested Florida Power Corporation to evalu-ate the design of the CR#3 Class IE electrical distribution system to detemine if the operability of safety related equip-ment, including associated control circuitry or instrumentation, can be adversely affected by short tem or long tem degradation in the grid system voltage.
Having completed our review of the infomation and analyses re-quested, we have detemined that the results of these analyses can be provided to you on or before December 15, 1976. We are e
unable to comply with your requested 30 day response schedule due to the extensiveness of the analyses requested.
If you wish to discuss our proposed schedule of response further, please feel free to contact me.
