4 Docket Nos. 50-327 and 50-328 2 FEB 1987 LICENSEE: Tennessee Valley Authority FACILITIES: Sequoyah Nuclear Plant
SUBJECT:
SUMMARY
OF PEETING TO DISCUSS OUTSTANDING ENGINEERING ISSUES On January 21, 1987, representatives of NRC and TVA met to discuss outstanding engineering issues regarding Sequoyah. Enclosure 1 lists the attendees.
- Enclosure 2 includes handouts provided by TVA at the meeting.
The review status of many issues were discussed. The issues included ampacity, superheat, cable pulling, instrun,ent sensing lines, bypass inoperable status indication system, Reg. Guide 1.97, Generic letter 83-28, concrete, design control, electrical calculations, Appendix J exemption, containment spray pump time, design baseline verification program, hydrogen, Diece-parts and con-tainment fan flooding. As a result of this meeting, the need for timely follow-up meetings / discussions were identified regarding cable pulling, superbeat, ampacity, piece-parts and hydrogen.

C.
Original ampacities were based on 3" trays while' 4" trays. wore use I
I Ampacity is inversely proportional to the increased depth' of fill which results from use of the deeper cable tray.
D. Engineering did not derate for fire retardant Duecable to thecoatings, above tray covers and bottcms and Appendix R fire wrap. inadequacie accomodate these doratings.
Problem Solution 1.
Developed and applied the revised ampacity standard using SWEC f technical expertise, industry standards and TVA specific testing (Re Bechtel has reviewed the standard as part of ECIG and DS-E12.6.3).
commented that it was acceptable while guestioning if we hadWhen sufficient conservatism in one area.

A. Safety Evaluation of Ice Condenser and Hydrogen Mitigation System %: ~-
Changes 1
TVA will perf orm an evaluation of all changes (ECNs/FCRs,,FCNs, TACFe, 1.DCRs and DFCRs) since UL on the saf ety-related portiontto'f the hydrogen mitigation system and ice condenser system to address NRCs ,
h4 concerns on contain:nent integrity. 'The evaluation vill comply with the objectives of the DBVP program as follows:
M M . To verify the adequacy of the plant modifications made since OL to N systems, or portions of systems, required to mitigate design basis events and to provide for saf e shutdown of the plant.
. To provide confidence that the modifications are supported by l W engineering analysis and documenta. tion.
To provide confidence that the modifications are made in conf ormance
'n .
with licensing commitments. .
g These objectives are being met by TVAs review that will entail the f ollowing steps :
\ Q 1. Identifying'all changes (ECNs, FCRs, FCNs, TACTS, LDCRs, and DFCRs)
Q involving systems *43 and 61 (hydrogen mitigation dnd ice' condenser systems, respectively). jl- .

. (/)
s Q 2. Identif y all changes that can aff ect the saf ety-related fdnetions of these systems.
,y -
%6 Evaluate these changes (item'2 above) against the design source (y / 3.
documents (FSAR. design criteria. technical specifications, or i other codes and standards, as required) to determine whether any of the changes vill reduce these systems ability to perform its
/
designated safety function or will violate licensing commitments.
- 4. Where necessary, USQDs and UDIEs will be completed or revised in accordance with TVA procedures.
- 5. Any deficiencies encountered from the review that require corrective action will be documented and processed in accordance with TVA procedures.
l l 6. A final report will be issued to su=marize and document the results -
of this review.
