REVIEW 0F AFFIDAVIT CF CHAN VAN VO DAVIS 1

In response to a request from B. Buckley, the Auxiliary Systems Branch (ASB) reviewed Sections 5, 6, and 7 of the subject affidavit, which relate to cold-pulling a 24-inch feedwater pump discharge line. The Auxiliary Systems Branch concluded that the pipe in question did not perform a safety-related function and that failure of this pipe would not prevent bringing the plant to a cold t

shutdown mode. An ASB staff member, N. Wagner, prepared an affidavit (enclosed) l which contains the bases for our conclusion.

AFFIDAVIT OF NORMAN H. WAGNER State of Maryland ) 33 County of Montgomery' )

Norman H. Wagner, having first been duly sworn, hereby states as follows: I am employed as an engineer in the Auxiliary Systems Branch of the Division of Systems Integration, Office of Nuclear Reactor Regula-

, tien and am the Staff reviewer of auxiliary systems for the Shearon Harris operating license application. My educational qualifications and professional experience are set forth immediately belpw.  ;

i Education B.S. - Chemical Engineering - C.C.N.Y., 1948 M.S. - Chemical Engineering, University of Cincinnati, 1952 Experience I have been with the U.S. Nuclear Regulatory Commission from its irception in 1975, with a shcrt period (frce January 1975) with the U.S.

Atccic Energy Corrission. In my career with the Nucitar Regulatory htw

i s

.Y .

.. -2 Comission I have been assigned to the Reactor Systems Branch, to the

,i Systems Interaction Branch and to the Auxiliary Systems Branch at times

! and in the capacities shown below:

, From January 1975 to approximately September 1980, I served as an engineer in the Reactor Systems Branch, with the title of Reactor Engineer. In that capacity I performed licensing case reviews, checking adherence of reactor systems in nuclear power plants to the rules and regulations stipulated by the Nuclear Regulatory Comission. In September of 1980 11was transferred to the newly formed Systems Interaction Branch where I, with other members of the branch, attempted to develop a systematic methodology for reviewing nuclear power plants .

, for adverse system interactions. I was transferred back to the Reactor Systems Branch in July 1981 when the Systems Interaction Branch was

~

dissolved, and then to the Auxiliary Systems Branch in December 1981 where I am presently; in this capacity my main effort is reviewing plant systems anc assuring compliance of these systems with the rules and regu-laticns of the t;uclear Regulatory Comission.

Response

I have reviewer 1 the Affidavit of Mr. Chan Van Vo Davis dated October 6, 1984 Mr. Davis alleges on pages 5 and 6 of his Affidavit that a 24 inch carbon steel pipe was " cold pulled" to fit the pipe to the discharge nozzle steam generator feed-water purrp 1A-NNS. This pump pumps water to the steam generators. -

Ficures 10.1.0-3 and 10.1.0-4 in the Shearon Harris Final Safe y Analysis Report (Amendment 15) are flow diagrams which include the pump

- in issue. It does not appear that there is a 24" pipe attached to the pump's discharge nozzle. The pump appears to have an 18" discharge nozzle.

Pipes leading in and out of the steam generator feed-water pump 1A-NNS, and the pump itself, do not perform a safety-related function.

Failure of that pump or its piping will not prevent bringing the Harris facility to a cold shutdown mode.

The concerns raised by Mr. Davis on pages 5 and 6 of his Affidavit relating to piping attached to steam generator feed-water pump 1A-NNS do not raise safety' concerns for the facility. This is also evident from the pump's designation IA-NNS. The NNS is the Applicants' nomen-clature for non-nuclear safety equipment.
