Hope Creek letter of 1/6/93 to T. Stevenson (Coltec)

HCT-93-11 l- Attna Mr. D. Wray, Systems Engineer PSE&G

Dear:

Hr. Wray After an extensive Engineering review by both our Systems and Engine Engineering groups, it has been determined that a substantial Safety

. Hazard'does not exist. Therefore Fairbanks Horse does not consider the event reported to us as a Part 21 from our. stand point. By copy of this letter to Mr. W. Haass, the USNRC is.being advised of our findings.

Furthermore,- a series of check valves were installed to prevent _the:

reverse flow .-discharge feeding intake, scenario. described.in1several letters sent-to1us. If the check valves are in place.'there can be'no reverse flow through'either of the pumps.

We have found the root cause to be that upon receipt of.-these_ pumps:at Fairbanks Horse,_they were' mismarked'with the wrong.part number. Only:.

4 of these pumps were ordered for Service Stock, and the location of the fourth pump is not at a Nuclear Site.

A check of our Parts Dedication Program'(SP 750) shows that a flow Echeck is required to-verify the correct rotation of<the pump. Thus in any. future Safety Related orders you can be assured'that the correct rotation pumps will be delivered.

-nsh Sincerely.

Michael S. Horinka Manager _ Quality: Assurance and Field' Quality
