Allegation Summary or staff suspected wrongdoing: (Recipient of the allegation shall summarize each concern here - provide additional detail on reverse side of form, ifnecessary. If entering allegation electronically, highilght Allegation Summary In bold and use larger font size)
O ed the NRC's Bob Bores on April 16, 2004 to Indicate tha)had Thmet with a concerned individual. Ihe concerned Individual described Issues with Hope Creek emergency diesel generators (EDGs) that a second concerned Individual (previously emoet P had provided.
The name of the former PSEG concerned Individual was not provided to thOn April 28, j
2004, theI a V I led to the Hope Creek Station and met with the SRI, Mel Gray to describe the statements ofi corncem. He had hand written notes which he verbally stated made the following assertions:
- 1. A Hope Creek EDG had problem a with metal filings or grit In Its lube oil or jacket water system.
This was causing lube oil or jacket water leaks. PSEG did a fix that was not the best.
- 2. Also, a shaft needed replacement, but was not because of cost.
Initial Follow-up:
The SRI searched the notifications for something along these lines and Identified notificatio -asa possible candidate. This notification was written on 4/26103 by a maintenance individual. The prob em described was that, because Engineering did not listen to the individual and flush the jacket water system, additional Jacket water seal leaks developed. The Inspector reviewed wit gthe initial response to the notification and both agreed it sounded similar to the statements of concern being made. The inspector toured all four EDGs wit to show him the jacket water and intercooler pumps and common shaft that was described ne notificaIon. Th Inspector also discussed with the system engineer (withl bservrig) any plans for jacket water flushing. The inspector determined that, based on perinuic Jacket water sampling, PSEG plans to flush B EDG jacket water system InApril 2006. This Is tracked under notificatio~ No other EDG engine flushes are planned. B EDG pump seals do not currently leak.
The SRI communicated t at he had talked to an Individual In June 2003 who believed that.
grit was the cause of chroic M pump seal failures. He talked with the Individual InJune 2003 when the A EDG Intercooler seal leaked and HC began to shutdown per TS because of the problem. The Individual believed that Jacket water system had grit from sand castings during initial fabrication, and grit embedded In seals and caused chronic leaks.-
PSEG subsequently disassembled the A EDG jacket water and Intercooler pumps and shaft InJuly 2003 and found a seized thrust bearing. One result of the root cause evaluation done on this was that chronic seal leaks on EDGs may have been due to lack of design sped numbers in the PSEG seal replacement procedure to check shaft thrust and bearing clearance. PSEG could not ensure jacket water and Intercooler pump seals were consistently being shimmed correctly w/o checking these parameters. This would look like wear out of seals prematurely. The Inspector referenced IR354/2003-004. It documents an NCV finding for PSEG not having design specifications in pump seal replacement procedure when Itwas available In avendor document previously used in a B EDG work order.
left the resident office thereafter (to support an unrelated public meeting that evening). -
The inspector performed follow-up insp t n Thursday and Friday, April 29-30, 2004, and determined the following details regarding notification 1 In the notification description:
- 1. An Individual stated that the Jac ter pump seal on the C EDG leaked In 9/02. The Individual Initiated alevel 2 notification at that time,. The Individual asserted in 9/02 the seals were likely falling due to corrosion products Inthe jacket water system.
- 2. The Individual's notification NOwN1was closed to order 70026906, then to 70026865 for PSEG engineering personnel to evaluate. PSEG engineering did not agree with the individual that the C EDG jacket water pump seal failed due to corrosion products. Engineering asserted that the jacket water seal faces were heavily worm. There was some debris Inthe soft side seal face, but this did not cause the seal failure.
Engineering concluded the seal wore due to being Inservice for 6 years. Therefore Engineering did not Identify ajacket water system flush asaa cq 9.Yajaction.
- 3. The Individual asserted In notificatlo mat, because engineering did not ensure the Jacket water system was flushed, there were additional Jacket water or Intercooler pump seal failures. He cited notification 20128763 where the B EDG developed a Jacket water leak. He further cited notification 20141632 where the BEDG common pump shaft for jacket water and Intercooler pumps had grooves and required replacem6nt.
waffilawag,Nvas closed based on engineering response that debris was not cause of seal leaks.
- 4. Notification 411!M!111111
Note:
The Inspector communicated the above four points t q 3,2004 d ndicited that his managerneYad additio al quetilos:
_p-n Monday, May 7.
- a. Who concluded that the soft material in the seal face could not cause the leak?
- b. What was the basis for deferring the B EDG flush until April 2006?
- c. What was the history of shaft replacement for all four EDGs?
- d. What was the history of pump seal replacements for all four EDGs?
