SUBJECT:
NRC INTEGRATED INSPECTION REPORT 50 327/97-08 AND 50 328/97-08
Dear Mr. Kingsley:
This refers to the inspection conducted on July 6 through August 23, 1997 at
the Sequoyah facility.
The enclosed report presents the results of this
inspection.
During the inspection period. your conduct of activities at the Sequoyah
facility were generally characterized by acceptable operations based on
routine control room observations and a downpower evolution. One exception
was noted with the realignment of the vital battery discussed in NRC
Inspection-Report 50 327.328/97-13. Maintenance was considered to be good
with exceptions for not properly installing a transformer core ground on the
main _ transformer resulting in Unit 2 being taken off-line and the poor
material condition of the control air system which caused a runback on both
units and a reactor trip on Unit 1.
Engineering was considered to be _ good
including the 10 CFR 50.59 program, improvements in the root cause program for
equipment-failures, and improvements in problem Evaluation Reports written for
equipment reliability problems. Overall plant support was considered to be
_ good.
Based on the results of this inspection, the NRC has determined that a
violation of NRC requirements occurred.
The violation is cited in the
enclosed Notice of Violation (Notice) and the circumstances surrounding it are
describedindetailinthe_subjectinspectionreport.
The violation involved-
-multiple stroking of a containment isolation valve and subsequently declaring
the valve operable without appropriate corrective action. Although this
violation meets criteria for a non-cited violation it is one of several
problems recently identified. associated with implementing inservice testing
I
requirements. Accordingly, a broad review of your program is warranted.
