Dear Mr. Eliason:
SUBJECT:
PRAIRIE ISLAND UNITS 1 AND 2 SHUTDOWN RISK AND OUTAGE
MANAGEMENT INSPECTION (NRC INSPECTION REPORT
50-282/92-201, 50-306/92-201)
We are forwarding the report of the shutdown risk and outage
management inspection conducted by the U.S. Nuclear Regulatory
Commission (NRC) staff from September 21 through November 20,
1992.
The activities inspected were authorized by NRC Operating
Licenses DPR-42 and DPR-60 for Prairie Island Nuclear Generating
Plant Units 1 and 2.
At the conclusion of the inspection, the
team discussed the findings with members of your staff.
The inspection team examined the adequacy of your dual unit
outage planning and conduct to evaluate the degree to which these
minimized the risk of initiating accident sequences during
shutdown conditions.
This inspection was conducted in two-
phases: (1) before the cutage, with a focus on outage planning,
and (2) during the outage, with a focus on the use of outage
controls for equipment being worked on, equipment returned to
service, and turnover of systems to operations.
The team found that your measures to minimize the risk of
initiating accident sequences during shutdown conditions were
detailed and comprehensive.
The shutdown risk program was sound
and appeared to be effective.
However, the team identified a
deficiency in the failure to follow procedures.
In addition, the
team noted that there appeared to be some confusion over the
concept of equipment available to perform a safety function
during plant shutdown versus operable equipment as defined in the
plant Technical Specifications.
The team found that the plant staff was very knowledgeable of its
duties and carried out the program competently and
professionally.
The presence and oversight of the plant
management was apparent and contributed to the safe conduct of-
the outage.
Among the strengths, of particular interest were;
use of the work control center to minimize control room traffic,
shutdown risk status boards at several plant locations, and the
shutdown safety assessment training.
