SUBJECT:

I&E BULLETIN 80-02 Inadequate Quality Assurance for Nuclear Supplied Equipment

Reference:

1) Letter from D. G. Eisenhut to R. Gridley of General Electric Company, Dated January 14, 1980 (Generic Task A-10)

Dear Mr. Grier:

The FitzPatrick Plant staff has reviewed and provides below the information requested by the subject bulletin. This information is presented in the same order as requested.

1.a. The feedwater spargers and thermal sler"as currently installed at the FitzPatrick Plant were manufactured oy Marvin Engineering Company. These components were supplied to the FitzPatrick Plant from General Electric. General Electric in turn procured the i

components from CBI Nuclear Company and further documentation indicates that the feedwater spargers were procured by CBI Nuclear from Marvin Engineering Company.

1.b. The feedwater sparger and thermal' sleeves were purchased by the Power Authority for use at the FitzPatrick Plant during 1978. These  ;

components were installed during the 1978 refueling outage.  !

l The design function during normal operation of the feedwater spar and thermal sleeves (as described in Section 3.3.4.6 of the FSAR)gers is to direct fr.edwater flow entering the reactor vessel radially inward from an area near the reactor vessel wall to mix the cooler feedwater with the downcomer flow from the steam separators before it contacts the vessel wall. The feedwater also serves to collapse the steam

I&E BULLETIN 80-02 Page voids in the mixing plenum and to subcool the water flowing to the jet pumps and recirculation pumps. The feedwater spargers and thermal sleeves do not perform any function under accident conditions.

2. As noted above, the feedwater spargers and thermal sleeves were installed during the 1978 refueling outage prior to the startup for Fuel Cycle

3. The plant is currently nearing the end of Fuel Cycle 3 and plans to conmence a refueling oucage prior to the start of Fuel Cycle 4 on May 3, 1980. Accordingly, no inspection of the feedwater spargers or therma sleeves has been possible since their installation. During Cycle 3 there has been no evidence of any failure or. malfunction of the feedwater spargers or thermal sleeves. During the 1980 refueling outage, a visual inspection of feedwater spargers will be conducted.

3. The feedwater spargers and thermal sleeves were received for the FitzPatrick Plant by General Electric. The General Electric Quality Assurance Program in effect at that time is described in NEC0-11209-3A, dated November 28, 1977. The components were installed by General Electric (under contract) under the same Quality Assurance Program . With respect to judging that the integrity of the components is sufficient to permit plant operation during normal and accident conditions, the FitzPatrick Plant staff notes that the Commission's Division of Operating Reactors, Office of Nuclear Reactor Regulation, accepted (in part), in Reference 1, the General Electric Company propritary Topical Report, NEDE-21821-02 titled "BWR Feedwater Nozzle /Sparger Final Report, Supplement 2, August if79." Since Reference 1 did not accept the recommended testing and inspection contained in Chapter 6 of NEDE-21821-02, the FitzPatrick Plant plans to implement the test and inspection recommendations provided by General Electric as a result of ongoing negotiations with the Commission concerning testing and inspection of the feedwater spargers and thermal sleeves, thereby providing assurance that the feedwater spargers and thermal sleeves will perform their intended function.

Very truly yours, - e i RJP:VC:brp lq lY RAYMOND J. PASTERNAK w
