Dear Mr. Cahill:
SUBJECT:
COMANCHE. PEAK EMERGENCY ~ RESPONSE GUIDELINES INSPECTION
'(50-445/89-59;.50-446/89-59)
This letter forwards the report of the emergency response guidelines (ERGS)
inspection performed by an NRC inspection team from August 14-25, 1989, at
Comanche Peak Steam Electric Station Unit 1.
The activities involved are
authorized by NRC Construction Permits CPPR-126 and CPPR-127 for'the Comanche
. Peak Steam Electric Station. At the conclusion of the inspection, the team
discussed the findings with the members of your staff identified in Attachment C
of<the. enclosed inspection' report.
Arees exami.ned during the inspection included: review of the ERGS, the documents
used.to develop the ERGS, the verification and validation program, and the ERG
training program.
In. addition, the inspection included a walkdown of the ERGS
in the control room and plant, evaluation of operator performance of ERGS on
your site-specific simulator, and performance of a human factors evaluation of
the ERGS. Details of the inspection are provided in the enclosed inspection
report.
The team-determined that the Comanche Peak ERGS, when used by trained operators,
can function to mitigate the consequences of an accident. However, the team
identified a number of weaknesses involving the development and. implementation
of the ERGS. These included the lack of timely engineering involvement in ERG
development and revision, calculation errors, lack of availability of tools and
equipment in the plant, inadequacy of the verification and validation process,
lack of lighting in some areas of the plant during accident conditions, questionable
ability-of certain safety injection isolation valves to close with a differential
pressure across them. and inadequate ERG modeling capability of the simulator.
The team observed that in the last year, the applicant has taken aggressive
actions to impron the plant-specific ERGS. These actions included perfonnance
,of three ERG au? 3 condrMd by the app icant s qua ity assurance department,

used to upgrade and enhance the ERGS.
In addition, an engineering task group
has been developed to resolve a number of engineering items related to the
ERGS.
