Docket No. 50-29 Mr. Robert H. Groce Licensing Engineer Yankee Atomic Electric Company 20 Turnpike Road Westboro, Massachussetts 01581

Dear Mr. Groce:

RE: TOPIC VIII-3.B Request for Additional Infomation 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 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 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 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 might compile would be inccmplete and would be sent to you for completion.

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

Si ncerely, W
