Docket Nos.: 50-369 and 50-370 Duke Power Company ATTN: Mr. William O. Parker, Jr.

Subject:

Auxiliary Feedwater System (TMI Item II.E.1.2)

(McGuire Nuclear Station, Units No. I and 2)

In response to TMI concerns, you submitted information pertaining to the automatic initiation of the a"xiliary)feedwater system (Action Plan Item II.E.1.2; NUREG-0578, Section 2.1.7.a. Based on our review of this infor-mation, we have' concluded that the McGuire Units 1 & 2 AFWS automatic initiation meets all safety grade requirements with ti'e exception of operating bypasses.

The McGuire FSAR states shat, during plant snuccown, the operator can manually defeat the automatic start of the auxiliary feedwater motor driven pumps on either low-low level in any steam generator or trip of both main feedwater pumps. The design does not include an automatic removal of this manual bypass 1

feature. This design is not in accordance with IEEE 279-1971 requirement 4.12 (i.e., operating bypasses) which states that, where operating requirements necessitate automatic or manual bypass of a protective function, the decign shall be such that the bypass will be removed automatically whenever perndssive conditions are not met.

Therefore, it is our position that automatic removal of this manual bypass be provided in accordance with IEEE 279-1971 since possible failure to remove this operating bypass could prevent the AFWS from performing its automatic safety function. Please provide sufficient information (i.e., logic diagram, electrical schematics, etc.) to demonstrate compliance with this position including identifi-cation and justification of any exceptions.

It is requested that this information be provided by September 29, 1980.

Sincerely,

()
