Docket No. 50-245 Mr. W. G. Counsil, Vice President Nuclear Engineering and Operations Northeast Nuclear Energ" Company Post Office Box 270 Hartford, Connecticut 06101

Dear Mr. Counsil:

RE: TOPIC VIII-3.B Request for Additional Infomation f

To complete the evaluation of Topic VIII-3.B, a list of all alams and voltage monitoring devices available to provide operability status indication to the I

operator for the Class IE batteries, associated chargers and direct current buses is required.

We have completed our search of the SEP Plant dockets for infomation relative j

to Topic VIII-3.B, "D. C. Power System Bus Voltage Monitoring and Annunciation".

This effort indicates that some of this infomation is available. However, our t

t experience has shown that only a portion of the alams and monitoring devices would be shown on the available drawings.

Thus, we expect that any list we i

might compile would be incomplete and would be sent to you for completion.

i Therefore, rather than going through the intemediate steps, you are requested to provide the listing descrit above within thirty days of receipt of this letter.

Sincerely,

{
