SUBJECT:
LASALLE INSPECTION REPORT 50-373/99001(DRP); S0-374/99001(DRP)
Dear Mr. Kingsley:
,
This refers to the inspection conducted January 6 through February 16,1999, at the LaSalle
j
Nuclear Power Station. The purpose of the inspection was to determine whether activities
authorized by the license were conducted safely and in accordance with NRC requirements. At
the conclusion of the inspection, the findings were discussed with those members of your staff
identified in the enclosed report. No cited violations of NRC requirements were identified during
the course of this inspection,
j
Overall, performance of plant personnel was acceptable. Operators were knowledgeable of
plant and equipment status, maintained accurate records, and effectively communicated
operational information. In two instances, which included a loss of the heater drain pump
supply to the reactor feedwater pumps and a decrease in the main condenser vacuum while
realigning the off-gas system, operators appropriately responded to the unplanned plant
transients which resulted from equipment prcolems. The decrease in condenser vacuum was
attributed to the leaking valves in the off-gas system and although the plant responded as
designed, plant material condition impacted operations.
Personnel errors occurred during the inspection period. Inattention to detail and lack of a
questioning attitude by maintenance and operations personnel resulted in lapses in
\\
configuration control and some problems with the foreign material exclusion (FME) program,
g
For exarnple, operators inadvertently drained 25,000 gallons of condensate to the Unit 2
suppression pool through a drain valve that was not closed, construction personnel terminated
electrical leads onto a breaker while out-of-service cards were affixed to the leads, and
maintenance personnel did not adequately secure an FME cover onto a disassembled
emergency core cooling system valve. Although none of the issues was safety significant, they
demonstrated the continuing need for management attention to address human performance at
LaSalle Station.
