SUBJECT: ROUTINE INTEGRATED INSPECTION 50 277/97-06 AND 50 278/97 06
Dear Mr. Smith:
This refers to the inspection conducted from August 10 through September 20,1997, at
the Peach Bottom Atomic Power Station, Delta, Pennsylvania. At the conclusion of the
inspection, the inspectors discussed the findings with Mr. G. Edwards and (thers of your
staff. The inspectors based these findings on independent observation of activities,
interviews, and document reviews.
During the six week period covered by this inspection. your operations staff responded
well to off normal and degraded conditions, most particularly the temporary loss of all the
I
Unit 2 drywell coolers and the fire in the 3B circulating water pump motor. Other plant
departments continued to support plant power operations and emergent work while still
preparing for the Unit 3 refueling outage which started on October 3,1997.
.We noted during this period two examples where personnel either failed to follow
procedures or failed to take adequate self checking measuces, resulting in one case in the
conduct of a surveillance test on the wrong unit. Moreover, two days after this inspection
period ended, your staff identified an event in which a safety related high pressure service
water (HPSW) pump was electrically uncoupled without being isolated because contractor
personnel thought they were working on a non-safety-related service water pump that was
electrically isolated. This event highlighted weaknesses in procedural adherence,
4
particularly the use of work package documentation at the job site, self checking, and a
questioning attitude that led to multiple breaches in work process barriers.
The HPSW event is of particular concern since it impacted a safety related piece of
equipment, it also represented the thirri significant industrial safety event since late
February at Peach Bottom, the other two being the unexpected start of a cooling tower fan
while a worker was preparing to take an oil sample from the fan gear box, and the injection
of chlorinated water into a circulating water bay while two workers were conducting a
pump inspection. Management's attention to effectively correcting the work clearance
process and worker performance weaknesses noted in these events is warranted,
particularly given the increase in the number of work activities and contract workers during
the Unit 3 outage.
