November 15, 1984 MEMORANDUM FOR:

W. D. Shafer, Branch Chief J~- Division of Reactor Projects FROM: W. G. Rogers, Senior Resident Inspector

SUBJECT:

PROFESSIONAL DISSENTING OPINION (DSO) CONCERNING OPERABILITY OF 120 VAC VITAL BUSES Earlier this year, I submitted a DSO over the Director of NRR, Division of Licensing, interpretation that a 120 VAC vital bus could be considered operable with non-Class lE power supplied to it.

11pon receipt of my DSO, you and other management members of

' Region III have worked in earnest to resolve my concerns. Based upon your last memorandum and the securing of a cortnittnent from Toledo Edison to consider a 120 VAC operabic only with Class lE

• power supplied, I consider my DSO resolved.

Thank you once again for your actions in this matter.
