January 10, 1985 OGTP-733 Memo to File Re: TDI Diesel Generator Owners Group Executive Comittee Meeting Minutes January 9,1985 File: MTS-4086 The subject meeting was held in Dallas, Texas. Those individuals present are identified in Attachment 1.
The meeting agenda (as amended during the meeting)
.is provided as Attachment 2.
TECHNICAL SESSION I. A. J. B. George called the meeting to order at 10:00 a.m. CST. Mr. George recapped the Executive Chair's meeting with H. R. Denton of the NRC on November 29, 1984.
- Mr. George stated that Mr.* Denton was advised.that the Owner's Group intended to close and41sperse -the TechnicaluStaff-in February 1985. He -also noted that the
' J NRC should give favorable attention to applications requesting less stringent maintenance and surveilliance requirements from those in the DR/OR reports if
,O suaaortie bai e oa eettieaal site exa ri ac - "r o.atoa acted that such 9911 -
cations would get appropriate consideration.
C. L. Ray continued that in later discussions witn C. H. Berlinger of the NRC, Mr. Berlinger felt that enough sup-port has already been provided to NRC to relax the 185 BMEP interim licensing restriction. Mr. Berlinger noted that NRC would not issue a singular action lif t-ing this requirement; rather this would be accounted for in each plant specific l
SER. Mr. Berlinger further stated than an endurance run for Comanche Peak, as had been previously requested by NRC, should not be necessary in light of the hours already logged on the Catawba engines. The Catawba runs should serve as the performance test for the V-16 engine.
- 8. C, L. Ray presented the status and schedule of the Phase ! and !! effort (Attach-t ments 3 through 7). A copy of the most recent NRC status report was distributed.
Little change from the previous month's NRC status was noted. Mr. Ray stated that indications from pNL personnel are that dates listed in the status report are not achievable.

be provided for TUGC0 by TDI. (Found some dimensions out of tolerance per TDI drawings.
Investigation of problem by TOI and TUGC0 revealed that areas where dimensions were not within tolerance would not result in any problems based on a design review and coerating experience to date of other engines.) The problem was evaluated under 10CFR Part 21 and found to be/not reportable. TDI does not plan to issue any fonn of service bulletin since'no problems have occurred or are anticipated.

Executive Committee Meeting January 9, 19es

PRDPOSAL FOR CLOSURE OF TDI OWNERS GROUP _
1 There are two distinct organi:ations which should be treated somewhat indepen-dently when considering closure of the TDI Owners Group. These are the TDI Owners Group Technical Staff and the TDI Owners Group Executive Comittee..The TDI Owners Group was formed to. collectively address the generic concerns raised due to the failure of the crankshaft at Shoreham and the subsequent loss of confidence in the TDI QA Program by the NRC. The TDI Owners Group Technical Staff was formed to provide the engineering services required to address these concerns and works under the direction of the Executive Comittee.
The TDI Owners Group Program Plan provided for the Design Review and Quality Revalidation (DR/QR) of the TDI diesel generators to be performed in two phases.
Phase I to be a design review of 16 generic components and Phase II being a DR/QR of 170t components on a plant specific basis for each of the. member utili-ties. Phase I was to be the basis of interim licensing and operation of near term plants and Phase II was to establish the long tem reliability of the TDI diesel generators. Phase I has been completed by the Technical Staff with the only outstanding item being receipt of final SER's from the NRC on the 16 generic components. The last of the Phase II DR/QR reports is scheduled for completion
- f,--- - by February.4,1985.and progress to. date indicates that the. schedule.is realistic.
This means that the base load work s: ope of the Technical" Staff will'be completed -- -
by the end of January 1985 and only the orderly closecut of files, etc. is anti-cipated for February,1985. This schedule and work scope is the basis for the
%f current budget projection.
The only function of the Technical S aff that could be anticipated to continue is the addressing of plant specific problems, inspection results, non-confomances, etc. Because of the availability of the Technical Staff, this work scope was superimposed on the Phase I and Phase II effort but invoiced on a plant specific basis. Because of the intermittent r.ature of this work, it is not practical to maintain a full-time Technical Staff to perfom this plant specific work scope.
Based on the'above, it.is recon 1 ended that'the Technical Staff proceed to close out and appropriately archive the files and data upon transmittal of the last Phase II DR/QR Report.
It is fully expected that this would be accomplished no later than the end of February 1955. At that time, funding of a full-time Technical Staff would be teminated.
This closure of the Technical Staff would be similar to the NRC plans for closing out the TDI Project Group headed by Carl Berlinger and placing responsibility for review of remaining diesel generator issued in the plant specific project groups, tir. Harold Denton advised the TDI Owrers Group Executive Steering Comittee in a meeting on December 9,19PA that it was his intention to dissolve the TDI Proji: cts L
Group upon completion of their review of Phase !.

The recormended alternative for addressing plant specific problems, inspection results, non-conformances, etc. subsequent to closure of the Technical Staff is to utilize the provisions, with any needed amendments, of the existing Utility-Duke MATS and Duke MATS-Consultant contracts which are currently in effect through June 1935.
In effect, the contracts would become continuing
( ',
services agreements with no specified scope or budget and would be exercised on an as'-needed basis by the specic utility requesting. services. The advan-tage of this ' approach is to maintain continuity which would serve to take full advantage of work performed thus far and minimize the risk of unnecessarily ra ij i g,g a,ny_A d d i t i eg1__g gner_i.C q p n_c.e r_,n s. These contracts could be renegotia-ted and,,extende_d~as needed beyond June 1985.
The TDI Owners Group Executive Committee has considerably more flexibility in deciding its future. The recommended alternative is to continue meeting on a periodic basis through June 1985 to share experiences and discuss concerns.
This could be done with the existing executive members or it could be decided to replace the existing representation with people who have more hands-on
~
technical experience. The need for meetings beyond June 1985 would be consider-ed at the June meeting. One point to consider in making a decision on this alternative is that the visibility of the Owners Group sets the TOI diesel gen-erators apart from other make diesel generators and other plant equipment as
.need.ing special consideration..

SUMMARY
This report summarizes the status of the TDI Diesel Generator Owners Group g
Tecnnical Program as of Febri;ary 1,1985.
As reported in the January status report, all Phase I work was completed 12/11/84.
(
NRC/PNL has requested a meeting with the Technical Staff on February 11, 1985 to L
discuss the results of PNL's Phase I review. Any remaining Pnase I questions can be answered at that time.
PNL plans to issue all Phase I TER's within one week of that meeting with NRC to issue the SER's 30 days hence.
The Phase II reports for Vogtle and WNPS-1 were issued 1/11/85 and 1/22/85 re-spectively (Attachment 1). Signoff of all Bellefonte reports and deletion justi-fications is complete with printing in progress. Bellefonte is on target to be issued 2/4/85 as scheduled.
Revisions to the Shoreham and Comanche Peak reports were issued 12/21/84 and 1/24/85 respectively. All other revisions should be issued by 2/15/85.
The Executive Chair Corraittee met with H. R. Denton on 1/10/85 to discuss work on Phase I and Phase II. Mr. Denton requested the meeting on 2/11/85 previously discussed. Nr. Denton indicated that the Owners should utilize the maintenance recommendations in the DR/QR reports for a period and request changes based on successful operation of the engines. Mr. Denton also noted that he saw no pro-blem with allowing the TDI engines to operate at 225 BMEP and this consideration would be given' in conjunction with the site specific SER's.
The Technical Staff is on target for a,n orderly closure February 28, 1985. b b ~
no further inspection results can be incorporated into the Phase 11 reports (for sites that have not completed their initial inspections) inspection schedule mon-itoring has been deleted. The final status report for the Owners Group Technical Program will be issued February 28, 1985.
