Texas Utilities Electric' Company
ATTN: Mr. William G. Counsil
Executive Vice President
400 North Olive Street, Lock Box 81

SUBJECT:
INSPECTION OF COMANCHE PEAK DESIGN VALIDATION PACKAGES:
50-445/88-29,50-446/88-25
Dear Mr. Counsil:
This letter fomards the results of the subject inspection conducted by the
NRC's Office of Special Projects (OSP). The inspection team was comprised of
personnel from OSP as well as contractors. The inspection took place from
February 22 through March 29, 1988 at Stone a Webster offices in Boston,
Massachusetts and Cherry Hill, New Jersey and at Ebasco offices at Comanche
Peak Steam Electric Station.
The team reviewed the TU Electric Design Valida-
tion Packages (DVP) in the areas of mechanical / fluids systems, electrical,
and systems interaction. For these areas, the review covered both the design
criteria and design criteria implementation. For the Systems Interaction
Program, the team perfonned field walkdowns in order to evaluate those
performed by Ebasco.
This inspection complements the NRC's previous reviews of DVPs which are docu-
mented in Inspection Reports 50-445/87-19,50-446/87-15, dated October 15, 1987
and 50-445/87-37, 50-446/87-28, dated February 8, 1988. The enclosed report
notes that there are two significant areas that the team was unable to review
since they were not complete, i.e., pipe break safe shutdown analyses and
voltage profile calculations down to 480Vac motor control centers. These
have been identified as Open Items S-30 and E-34, respectively. As was done
in the previous reports, the enclosed report identifies technical Open Items
in cases where (1) design criteria were considered inconsistent with the FSAR
,
t
!
or industry standards or (2) additional justification and/or analysis was
necessary to confirm existing designs or hardware. Our final conclusions on
l
the design validation process will be based on a followup inspection which will
l
include resolving Open Items identified in this and the previous inspection
reports and additional inspections (as noted previously) of design areas not yet
l
l
inspected. To support the followup inspection, you are requested to provide a
written response to this inspection report.
Your response should address the
Open Items, their safety significance, and the extent that these items may
pertain to documents not reviewed by the NRC.
This NRC inspection has included documents in the review sample that were
also reviewed by the TV Electric Engineering Functional Evaluation (EFE)
Program, as well as other documents. We will require that you review this NRC
report with regard to (1) significant items identified by the team (which you

would expect EFE also to have identified) which EFE failed to identify and
I
(2) significant items identified by the team for documents not in EFE's
i
'
review scope, i.e., to determine whether this scope is adequate.
In sumary, the following actions are required for the NRC to complete its
review of Design Validation Packages and the Project Status Reports:
(1)
additional inspections for Open Items S-30 and E-34, (2) TV Electric's written
response to all Open Items identified in NRC design inspections, (3) TV
Electric's review of NRC results with regard to potential enhancement of the
l
l
EFE program, ano (4) NRC followup inspections as required to assess TU Electric's
!
'
actions, i.e., (2) and (3). Your prompt actions are requested as it is our
intent to reflect all of the above matters in the Safety Evaluation Report (s)
on the Project Status Reports for these disciplines.
The NRC followup inspec-
tion scheduled for the week of April 25, 1988 at Stone and Webster offices in
Boston, Massachusetts is intended to accomplish (4) above, to the extent that
)
TU Electric actions are completed at that time. Additional followup inspections
i
will be scheduled as required.
l
In accordance with 10 CFR 2.790(a), a copy of this letter and its enclosure
will be placed in the NRC Public. Document Room.
