Dear Mr. Cahill:
This refers to the inspection conducted by Mr. Peter Stanish and
another NRC consultant during the period February 8 through
March 7, 1989, of activities authorized by NRC Construction Permits
CPPR-126 and CPPR-127 for the Comanche Peak Steam Electric Station,
Units 1 and 2, and to the discussion of our findings with you and
other members of your staff at the conclusion of the inspection.
The enclosed copy of our inspection report identifies areas
examined during the inspection.
Within these areas, the inspection
consisted of selective examination of procedures and representative
records, interviews with personnel, and observations by the
inspectors.
During this inspection, it was found that certain of your
activities were in violation of NRC requirements, as specified in
the enclosed Notice of Violation.
A written response to these
violations is required.
The NRC acknowledges that during the exit meeting on March 7, 1989,
TU Electric management expressed disagreement with the NRC position
i
that the errors detected by the NRC in Stone and Webster
!
'
Engineering Corporation's (SWEC's) calculations for piping and pipe
supports constitute a violation of Criterion III of 10 CFR 50,
/
Appendix B.
This Criterion states, in part,
. . . design control
"
measures shall provide for verifying or checking the adequacy of
1
design .
."
Implicit in the requirement to establish these
. .
$o
measures is that they be effective in identifying errors in the
%g@
design.
Based on the extremely high rate of relatively obvious
no
errors identified by the NRC (errors in 19 of 28 design
@8
calculations reviewed), it is our opinion that the implementation
MO
of the governing procedures for design control was inadequate.
The
- M
citation could have been against either Criterion III or
So
Criterion V.
We have concluded that a citation against
@@
Criterion III is appropriate.
