DR HENRY MYERS' COMMENTS ON INSPECTION FIFORT
50-327/87-31 and 50-328/87-31
,
The following comments on the subject inspection report on the TVA's
Design Baseline and Verification Program (DBVP) for the Sequoyah Nuclear
Power Plant were provided by Dr. Henry Myers of the House Interior
CannitteetStaff to Ccngressional Affairs. The comments are keyed to the
indicated secticas of the report and its cover letter.
As a general corrent, the report declares that prcblems are resolved
without supporting that declaration. Also, the report dces not spell out
things like DVBP.
(1) Two qualifications are not spelled out or defined
(2) Oces this ser.tence say that the NRC approves the report?
(3) Was the purpose of the inspection achieved? (See page 1 of report,
,
the first two sentences under 2. purpose.)
(4) 4.1 Operations
4.2 Mechanical Systems
4.3 Mechanical Components
4.4 Nuclear Engineering
4.5 Electric Power
4.6 Instrumertation and Control
4.7 Civil / Structural Engineering
- See dupli: ate paragraphs on pages 3 and 4.
Is the page 4 paragraph out
of order?
- All of the summary is out of order.
- Is the paragraph at the top of page a talking atcut all or part of
Sequoyah? In essence, are all paragraphs talking about all of Sequoyah or
'
just the particular subject covered?
- Does "closed" mean satisfactorily handled?
(Page 5) *** Does this mean no deficiencies at all?
(5) Does this mean they are fixed?
(6) (page 2) Does this mean "operations of the plant" or "operations of the
DBVP7"
l

.
(7) (page 6) This is a major itee.
(8)(page7) Problem
(9) (page 8) What is a "non-administrative change?"
o
(10) (page 8) Do not "implement" a punch list items. You address the
problems on the punch list and then solve the problems pointed out by the
punch list. Henry believes that the report could be saying that the
problems were addressed but not solved.
(11) (page 12) 357 action items and no way to determine if the deficiercy
is really fixed.
Inspection report does not indicate if things are being
fixed.
(12)AskHaroldwhathethinksoftheproblemsonpage 12, 13, 14 and 15
'
(notallindetail).
DBVP did not find them but the EA found them.
No
/
indication' that problems are being resolved.
(13) (page 15) What is "the project" and is acceptable to do calculations
after restart?
(14) (page 16) What are these documents?
It would be helpful for a one or
two line description on each one.
(15) (page 17) Does this mean that EA only reviewed three punch list items?
(16) General (page 16-17) There is a lack of seismic calculations to
confirm assumptions.
,
(17) (page 17 and 18) Section 4.2.4 is confusing.
(18) (page 25) What problems were reviewed? What did TVA do to resolve
them?
(19) (page 25) needs a look
(20)(page29) Calculation 870223 was the basis for cancelling the
variance. Does 86118 mean it was done befoce 870223?
Is this an
error-should 86118 be 860118 or is TVA pulling something?
(21) (page 31) The punch list review shows that errors were found.
Is this
falsifications? Who will confins a fix here?
(22) (page 31) Disagrees with the last sentence because there is no
substantiation of the claims.
(23) (page 31) "As built" verification did not appear in the IDI report on
ERC.
Henry says the process is too corplicated to be handled by Ebnetter-and
certainly too complex to be handled by the Commission. He feels that
Sequoyah and TVA are generally worse than Zimer.

SUBJECT:
INSPECTION REPORT NOS. 50-327/87-31 AND 50-328/87-31
This' letter forwards the results of a special inspection of TVA's Design
Baseline and Verification Program (OBVP) for the Sequoyah Nuclear Power
Plant, conducted at the plant site and in your Cedar Bluffs Offices between
June 29 and July 24, 1987.
The NRC inspection team was comprised of a multi-
discipline team of personnel from the Office of Nuclear Reactor Regulation
from consulting firms, and from the Region II Office.
The team concentrated on
the resolution and corrective action for the findings of the OBVP.
The team
also reviewed the corrective actions resulting from independent oversight of
this program by TVA's Engineering Assurance group and evaluated TVA's actions
in response to previous NRC design control and OBVP inspection reports.
internal reports (1) EA-OR-001, Engineering Assurance Oversight Review Report,
"Sequoyah Nuclear Plant - Unit 2 Design Baseline and Verificatico Program,"
dated April 29, 1987, and (2) the SQN OBVP Unit 2 Phase I report, dated May 29,
1987, characterize the program, its findings, and the Engineering Assurance
oversight effort.
These reports were also revjewed during this inspection.
to
As a result of the inspection, the NRC team conp"luded that the DBVP was generally
conducted in accordance with the program plan.TImplementation by both OBVP
personnel and the Engineering Assurance oversight group appears to have been
adequate in g instances sampled by the inspection team within the scope of
the program areas inspected to date.

'TVA provided a written response (R. Gridley letter dated October 27,1987)
addressing the observations identified in Appendix A of the enclosec report in
advance of the issuing of this report.
The substance of these observations had
been communicated verbally to TVA during the inspection.
An additienal NRC
inspection (Report 327, 328/87-64) was conducted on October 26-30, 1987.
This
subsequent inspection addressed many of the open observations addressed in the
enclosed report.
The NRC's evaluation of your response to this letter .<ill be
documsnted in inspection report 327, 328/87-64.
Any observations remaining
open at restart will require an evaluation of acceptability for suc
estart by
both TVA and the NRC.
In accordance with 10 CFR 2.790(a), a copy of this letter and the erclosure will
be placed in the NRC Public Document Room.
Should you have any questions concerning this inspection, please co tact me or
