PASNY letter, J.P.

Bayne to H.R.

Denton dated July 13, 1982 (JPN-82-61)

Dear Sirs The Power Authority transmitted the reassessment of the FitzPatrick plant, for conformance to Appendix R, to the NRC via the referenced letter.

During subsequent discussions with the NRC staff, they re-quested clarification of the definitions of DC power and control circuits.

The requested information was telecopied to the NRC on December 7, 1982 and is confirmed in Attachment 1 to this letter.

If the NRC staff determines that additional information is needed to assist their review, the Power Authority will provide such information as quickly as is reasonably possible.

If you have any further questions, please contact Mr. J.A. Gray, Jr. of my staff.

Very truly yours, D

a Executive Vice President l

to JPN-82-90 December 17, 1982 DC power circuits are defined as all main feeders to buses and circuits which provide motive power to DC components.

DC control circuits are defined as circuits which control the delivery of electrical power to components.

These circuits are connected to the secondary side of the fuse and provide such functions as control of relays, indicator lights, etc.
