Dear Mr. Schnell:

SUBJECT:

CALLAWAY NUCLEAR PLANT - CLOSURE OF RESPONSE TO GENERIC LETTER 91-06, " RESOLUTION OF GENERIC ISSUE A-30, ' ADEQUACY OF SAFETY-RELATED DC POWER SUPPLIES'" (TAC NO. M81422)

On April 29, 1991, the NRC issued Generic Letter (GL) 91-06, " Resolution of Generic Issue A-30, ' Adequacy of Safety-Related DC Power Supplies.'" The GL implemented the staff's resolution of Generic Issue (GI) A-30 as part of the resolution of GI 128, " Electrical Power Reliability." The GL requested that licensees provide written responses to several questions to allow the staff to determine whether any additional actions were required.

By letter dated Septaber 6,1991, you provided certified responses to each of the questions of GL 91-06 for the Callaway Nuclear Plant. The staff has reviewed these responses and finds that they satisfy the reporting require-ments of the GL. This completes the staff's activities associated with TAC No.

M81422.

Sincerely, Original Signed By:

L. Raynard Wharton, Project Manager Project Directorate III-3 Division of Reactor Projects - III/IV/V Office of Nuclear Reactor Regulation 1
