Dear Mr. Sieber:
SUBJECT:
NRC PILOT STATION BLACKOUT TEAM INSPECTION NRC
COMBINED INSPECTION REPORT NOS. 50-334/93-80 AND 50-412/93-80
The enclosed report refers to the Pilot Station Blackout Team Inspection, led by
Mr. James Trapp of this office, on August 30 through September 3,1993, at the Beaver
Valley Power Station in Shippingport, Pennsylvania. The purpose of this inspection was to
.'
review your programs, procedures, training, equipment, systems and supporting
documentation for implementing the Station Blackout Rule,10 CFR 50.63. At the
conclusion of the inspection, the team findings were discussed with you and members of your
staff.
This inspection was the first station blackout inspection conducted by Region I. The
inspection team was comprised of headquarters staff and regional inspectors and used a draft
temporary instruction for inspection guidance. The actions taken to implement the station
blackout rule are safety significant because many of the systems required for decay heat
removal and containment cooling are dependent on the availability of alternating current (ac)
power. In the event of a station blackout, a relatively few systems, that do not require ac
power, are depended upon to remove decay heat. The consequences of the failure of this
equipment to operate could be severe.
,
The team concluded that appropriate actions had been completed to implement the station
blackout rule. However, the information provided to the NRC in your June 21,1993, letter
is currently being reviewed by the Office of Nuclear Reactor Regulation and was not
reviewed during this inspection. The inspection reviewed aspects of several functional areas
and generally identified strong performance. In particular, the team identified thorough
operator station blackout training, detailed and sound station blackout procedures, high
quality modification documentation, and a knowledgeable staff.
,
In accordance with 10 CFR 2.790 of the Commission's regulations, a copy of this letter and
the enclosed inspection report will be placed in the NRC Public Document Room.
