SUBJECT: NRC INSPECTION REPORT N05, 50-445/92-49; 50-446/92-49
This refers to the inspection conducted by Mr. P. M. Madden of the Office of
Nuclear Reactor Regulation, and the inspectors identified in the attached
report, on November 16-20, 1992.
The inspection included a review of
activities authorized for the Comanche Peak Steam Electric Station, Units 1
and 2, facility.
At the conclusion of the inspection, the findings were
discussed with Messrs. C. L. Terry, R. D. Walker, and those members of your
staff identified in the enclosed report.
Areas examined during the inspection included implementation of the approved
fire Protection Program for Unit 2, selective review of your design and
implementation of features to support fire protection of safe shutdown
capability, and an assessment of the ability of a fire safe shutdown to be
implemented.
Other areas examined and details are identified in the enclosed
inspection report.
Within the scope of the inspection, no violations or deviations were
identified.
However, six unresolved items were identified during this
inspection.
The six unresolved items, which are discussed in detail in the enclosed
inspection report, concern potential fire induced short circuiting and
subsequent failure of motor-operated valves required for safe shutdown; the
scope of breaker and relay preventive maintenance and testing in safe shutdown
circuitry; assumptions in the high impedance fault study required by Generic Letter 86-10; selection and application of the mally actuated fire suppression
heads; derating of emergency ligh.ing batteries in areas of elevated ambient
temperatures; and the design adequacy of a water curtain intended to satisfy
separation criteria.
The unresolved items are further discussed in the
Executive Summary of the attached report.
Further, it was found that the reactor coolant pump lube oil collection system
had neither tank level monitoring instrumentation nor administrative controls

to periodically measure and dispose of any lube oil leakage.
It is our
understanding that during the exit meeting on November 20, 1992,
Mr. R. D. Walker, Manager of Regulatory Affairs for the Nuclear Engineering
Organization, connitted to have administrative controls for both units in
place prior to Unit 2 fuel load.
in a followup discussion on December 15,
1992, Mr. Walker indicated that the Unit I tanks had been sounded and drained
during the week of December 6, 1992,
if your understanding of the commitment
differs from ours, please contact me immediately.
There were also six additional items which will require inspection followup.
These are further discussed in the Executive Summary of the enclosed report.
One of these items involved numerous deficiencies found in an approved Unit 2
abnormal operating procedure.
The extent of the identified deficiencies led
to a more generic concern with your validation efforts for Unit 2 procedures.
Accordingly, a separate prelicensing inspection regarding this issue is
planned.
in accordance with 10 CfR Part 2.790 of the llRC's " Rules of Practice," a copy
of this letter and its enclosure will be placed in the NRC Public Document
Room.
Should you have any questions concerning this inspection, we will be pleased
to discuss them with you.
Sincerely,
/
