Mr. Harold R. Denton, Director Office of Nuclear Reactor Regulation U.S. Nuclear Regulatory Commission 7920 Norfolk Avenue Room P-404A Bethesda, Maryland 20814 Re: Long Island Lighting Company; Shoreham Nuclear Power Station, Unit 1; Docket No. 50-322-OL

Dear Mr. Denton:

On Thursday, January 26, you chaired a meeting on diesel generators manufactured by Transamerica Delaval, Inc. ("TDI") at which you expressed your concern with the many problems experi-enced by TDI diesels. As counsel for Suffolk County in the licensing proceedings for the Shoreham plant, we recently obtained information which may have significant safety and other implica-tions for the TDI diesels _at Shoreham. That information, which is detailed and documented in the attached memorandum, indicates that the NRC Staff Region 1 inspectors who conducted an inspection on July 28-29, 1983 of a sampling of replacement cylinder heads to be installed in the TDI diesel generators at Shoreham based their findings of no violations or nonconformances upon incorrect and invalid information. See Inspection Report No. 50-322/83-25 (the

" Inspection Report").

First, a cracked cylinder head was accepted at Shoreham because TDI informed the NRC inspectors that TDI's established criterion is to accept cracked heads if they pass a hydrostatic test without leaking. In fact, TDI's quality assurance documents do not provide that cracked cylinder heads are acceptable.

Second, the NRC inspectors used invalid standards for accept-able firedeck wall thickness in cylinder heads, and accepted a non-existent " engineering disposition" to justify a minimum wall thickness below the apparent specification.

s HEREFATRICK, IACEMART, HarA, CumteroPunu & PHIIAIPS Mr. Harold R. Denton February 3, 1984 Page 2 It is now clea;.that the findings of the Inspection Report are incorrect and that inadequate and deficient replacement.cyl-

/ inder heads are installed in the Shoreham diesels. Apparently, the only inspection of replacement cylinder heads made since July was the hydrostatic testing of two heads by LILCO in October 1983.

LILCO's consultant, Failure Analysis Associates, noted corrosion of the cylinder liner in cylinders of two Shoreham diesels, but

.apparently did not inspect the cylinder heads for cracks or other defects.

In view of the foregoing, Suffolk County hereby requests that the NRC Staff promptly undertake a complete inspection of each of the 24 cylinder heads installed in the three Shoreham diesels, as well as any cpare cylinder heads onsite, to determine whether or not they comply fully with all applicable standards. Those stan-dards should be fully. justified by appropriate engineering and design documentation _that complies with NRC regulatory require-ments.

Because of the significance of these matters, copies of this letter and the accompanying memorandum are being sent to the Licensing Board, all parties, TDI and others on the service list.

February 3, 1984 RE: NRC Region 1 Inspection Report No. 50-322/83-25:

Replacement Cylinder Heads at Shoreham By letter dated August 15, 1983, NRC Region 1 transmitted to LILCO the subject Inspection Report concerning the inspection on July 28-29, 1983, of replacement cylinder heads manufactured by Transamerica Delaval, Inc. ("TDI") to be installed in the emer-gency diesel generators at Shoreham. A copy of that letter and Inspection Report are attached as Exhibit A.

By letter of August 23, 1983 (attached as Exhibit B), Suffo]k County requested production of certain documents referred to in the Inspection Report on which NRC Staff findings were based.

TDI, by its counsel, finally responded to these requests by letter of January 24, 1984 (attached as Exhibit C). That response estab-lishes that the Region 1 inspectors relied upon incorrect and invalid information to justify their conclusions.

1. Cracked Cylinder Head; Incorrect Acceptance Standard.

NRC inspectors visually inspected 13 TDI cylinder heads, using TDI

4 KIRKPATRICN, LOCMMART, HILL, CHMISTOPHEN & PHutt.rPs MEMORANDUM February 3, 1984 Page 2 QA procedure 600-10, Addendum A, Visual Inspection Procedure.

Presumably all cylinder heads had been previously inspected

visually by TDI under this procedure and by LILCO under its QA program. The NRC inspectors found a 3/8 inch long " indication,"

or crack, in one cylinder head, and noted in the Inspection Report that the cracked head was unacceptable under the TDI Visual Inspection Procedure.

However, TDI then was permitted to evaluate the cracked head.

TDI informed the.NRC inspectors that under TDI's " acceptance-rejection criteria established by [TDI] Engineering," cracks are acceptable so long as they do not leak under hydrostatic testing.

Suffolk County requested production of TDI documents which estab-lish that criterion (see Exhibit B). TDI's response (see Exhibit C) was.its Hydrostatic Testing Procedure, 600-70, Rev. 3 (attached as Exhibit D), with particular reference to paragraph 3.5.4. That provision merely states that if a component leaks during testing, the leaks will be repaired. Nothing in this Procedure sugaests j that components known to be cracked and unacceptable under TDI's Visual Inspection Procedure will nevertheless be acceptable if they do not leak under hydrostatic testing. Because TDI's re-sponse for documents, after some five months, purports to be accurate and complete, it must concluded that there are no TDI

EtaEFATRICE, IACEMART, Han, Cuassrorumm & Putuurs MEMORANDUM February 3, 1984 Page 3 documents which support the information given to the NRC inspec-tors, and that such information was incorrect.

In addition, if TDI's QA program had permitted cracked cylinder heads to be installed in emergency diesel engines at Shoreham, the NRC Staff should have questioned whether such QA standards are proper and justified. Apparently the Staff did not make any such' inquiry or seek engineering and design justifi-cation. They simply allowed a cracked cylinder head to be installed at.a nuclear power plant because TDI said that was acceptable.

2. Firedeck Wall Thickness; Unjustified Acceptance Stan-dards. The NRC inspectors examined the firedeck wall thickness of thirteen cylinder heads, finding variances in thickness ranging from 0.464 inch to 0.881 inch. The Inspection Report (para.

2.2.b) states that the firedeck wall thickness " acceptance stan-dard was 0.500 inch +j.005 inch instrument accuracy and + . 010 inch per applicable drawings," and that " nominal firedeck thick-

, -ness is specified as 0.500 inch." There is no explanation in the Inspection Report as to why the inspectors did not view as unac-ceptable the large number of thickness readings which exceeded the maximum firedeck thickness.

. MEMORANDUM February 3, 1984 Page 4, In response to the County's request for " documents which establish the acceptance standard (s) for the thickness of the Delaval cylinder head firedeck wall" (see Exhibit B), TDI stated:

The acceptance standard was established by Inspection Report 00783 which you already have. That report is the only responsive document.

See Exhibit C (emphasis added). The referenced report is a single

. page TDI inspection report, dated February 21, 1981, covering the inspection of four cylinder heads. A copy of TDI inspection report 00783 is attached as Exhibit E. The TDI inspection report contains no detailed specifications or acceptance standards for firedeck wall thickness of cylinder heads. It shows only the following:

a. Under the heading " Description of De'.riation" there is set forth the thickness of the firedecks of 4 cylinder heads measured by ultrasonic test (U.T.) at four unspecified points.

I The thickness ranges from 0.420 inch to 0.768 inch,

b. Under the heading "Cause" are the words " Core Shift."

l l Presumably this indicates that the large variances in firedeck thickness were caused by a core shift in the molds during the casting process.

c. Under the heading " Comments" opposite the initials "ENG" there is written " Functionally Acceptable (.400 Min. Tolerance)."

KINEPATHICK, LocxHART, UILL, CHNINTOPHEn & PHILLIPS MEMORANDUM February 3, 1984 Page 5 On its face, then, the TDI inspection report 00783 appears to be merely an unexplained waiver by Mr. Pratt for the engineering section of TDI of the specified minimum firedeck thickness of 0.490 inch (0.500 inch - .010 inch) for four particular cylinder heads which were out of specification because of a core shift.

However, TDI has interpreted this single inspection report as the only document which establishes the acceptance standards for the thickness of the firedeck wall. This means that TDI has no standards for maximum firedeck wall thickness, and a minimum thickness standard of 0.400 inch.

The NRC Inspection Report thu; incorrectly states:

The nominal firedeck thickness is specified as 0.500 inch. However, the Engineering Department of TDI has set down as policy, via TCI (sic) inspection report No. Q0783, that 0.433 inches shall be the minimum acceptable thickness.

S.ince the readings (of firedeck wall thickness taken by the NRC inspectors] do not fall below this minimum, they are considered acceptable.

Exhibit A, para. 2.2.b. This statement is incorrect because, according to TDI, there is no nominal specified firedeck wall acceptance criterion other than as stated in TDI inspection report 00783, that criterion is a minimum of 0.400 inch, not 0.433 inch, and there is no evidence that inspection report 00783 states the

" policy" of TDI for the production of all cylinder heads. The

KINEPATERICK, IABCMuART, Harz, Cumistornam & Puin.t.rra

. MEMORANDUM February 3, 1984 Page 6 reliance by the NRC inspectors on TDI inspection report 00783 for their inspection findings is inexplicable.

In.its letter transmitting the NRC Inspection Report (Exhibit A), the Staff states:

Further discussions with Mr. J. Kammeyer on August 12, 1983, provided information that the engineering acceptance criterion for engine firedeck wall thickness was established as 0.400 inches in an engi-neering disposition dated February 22, 1981, regarding a quality control finding of a thickness of 0.433 inches on head 4 A2.

Exhibit A, letter at 1. TDI's response (Exhibit C) to the l County's request for that " engineering disposition dated February 22, 1981" is that no such document exists. Thus, Mr. Kammeyer of i

i Stone & Webster Engineering Company, which works for LILCO, furn-ished incorrect information to the Staff. We do not know why the Staff relied upon that information without obtaining a copy of the alleged " engineering disposition."

Immediately after receipt of the NRC Inspection Report, an attorney for Suffolk County, Mr. Alan Dynner, telephoned Mr.

Edward Greenman of NRC Region 1 to discuss the acceptance of the cracked cylinder head and the standards for firedeck wall thick-l ness. Mr. Greenman stated that he believed the NRC inspectors had reviewed documents which adequately supported their findings, but that such documents were no longer in the possession of the Staff.

KInuPATHIcx, LocxHART, IIILL, CHNIMTOPHER & PHILLIPH MEMORANDUM February 3, 1984 Page 7 This prompted the County's request for production of documents (Exhibit B).

As discussed above, TDI's response (Exhibit C) demonstrates that there are no documents which justify acceptance of a cracked cylinder head. The County also requested production of all engineering analyses, reports, evalu-ations or other documents regarding the justification for applying a minimum acceptable firedeck thickness of less than 0.500 inch.

Exhibit B, para. 2.

TDI's response states that aside from TDI inspection report 00783 (Exhibit E), "there are no additional documents responsive to this request." (Emphasis added). This indicates that Mr.

Pratt's waiver of defects in four cylinder heads in February 1981 became the general TDI acceptance criterion with no analyses of the effect of the lower minimum thickness standard or the absence of a maximum thickness standard upon the design and manufacture of TDI cylinder heads. This probably violates applicable NRC regu-lations in 10 C.F.R Part 50, Appendix A and Appendix B.

In conclusion, it is clear that the NRC Inspection Report contains faulty conclusions based upon incorrect and invalid in-formation. The replacement cylinder heads installed at Shoreham The County received inspection report 00783 in early October 1983 from LILCO. The County then assumed that there must be other documents. The response from TDI was not given until its letter of January 24, 1984 (Exhibit C).

These matters may have significant safety significance and, in addition, potentially entail the furnishing of false or misleading inform-ation to the NRC Staff and questionable inspection procedures and conclusions by the Staff.

Subject:

Inspection No. 50-322/83-25 i This refers to the special safety inspection conducted by Mr. Richard Harris of

, this office on July 28 and 29,1983, at Shoreham Nuclear Power Station of activities authorized by NRC License No. CPPR-95 and to the discussions of our i findings held by Mr. Harris with Mr. R. Purcell of your staff at the conclusion 1

of the inspection.

Areas examined during this inspection are described in the NRC Region I Inspection Report which is enclosed with this letter. Within these areas, the inspection consisted of selective examinations of procedures and. representative records, interviews with personnel, measurements made by the inspector, and cbservations by the inspector.

Within the scope of the inspection, no violations were observed.

Information contained within the enclosed inspection report has been discussed with Mr. Youngling of your staff by telephone on August 12, 1983. During this discussion, it was concluded that the inspection report contained no informa-

tion that you considered proprietary; therefore a copy of this letter and its enclosures are being placed in the NRC's Public Document Room.

i Further discussions with Mr. J. Kammeyer on August 12, 1983, provided informa-tion that the engineering acceptance criterion for engine firedeck wall thickness was established as 0.400 inches in an engineering disposition dated February 22, 1981, regarding a quality control finding of a thickness of 0.433 inches on head A2. This criterion was then applied to other heads, specifically, the G and H series heads which were the object of this inspection.

2.0 Indeoendent Measurements - NRC Nondestructive Examinations (NDE)

An.onsite independent nondestructive examination (NDE) was conducted at the site on July 28 and 29, 1983. This inspection was conducted by-regional based NDE personnel.

The purpose of this examination was to determine the ad2quacy of licen-see's quality control program on incoming vendor supplied equipment. This was accomplished by performing a visual, thickness and liquid penetrant examination of the material selected. Selected for inspection were 13 Standby Diesel Generator Cylinder Heads received for replacement of present heads.

2.2 Nondestructive Examinations Examinations were performed using NRC procedures and those submitted by the licensee's vendor, Transamerican Delaval, Incorporated (TDI).

The following examinations were performed:

F 3

a.Liould penetrant Examinations Three Diesel Generator Heads were examined per NRC procedure NDE 9, Rev.

O. Areas inspected by the liquid penetrant method were as follows.

Diesel Generator Head S/N Area G-95 Three valve seat araas E-71 Four valve seat areas H-56 Two valve seat areas A total of nine valve seat areas were inspected.

Results Eight areas inspected had no apparent indications. One area had a linear indication of approximately six inches with minimal bleed out at an area where the stellite interfaces with the base material. Further investi-gation revealed this to be a nonrelevant indication created by machining.

b. Thickness Measurements Thirteen Diesel Generator Heads were examined using a Nortec'124 digital thickness gauge. Areas examined for thickness were in the Cylinder Head firedeck wall. Readings were taken on final machined finish. The accep-tance standard was 0.500 inch .005 inch instrument accuracy and .010 inch per applicable drawings.

Results All readings of 0.485 inch and below were recorded and noted for the following Cylinder Heads (as noted on attachments).

Diesel Generator Heads SN Area Reading, inches G-19 3 .483 l

G-56 1&2 .478/.469 H-67 3 .485 G-52 3 .464 H-60 3 .479 l G-53 3 .484 G-89 3 .485 H-34 2&3 .485/460 The nominal firedeck thickness is specified as 0.500 inch. However, the Engineering Department of TDI has set down as policy, via TC1 inspection report No. Q0783, that 0.433 inches shall be the minimum acceptable thickness. Since the readings listed do not fall below this minimum, they are considered acceptable.

c. Visual Insoection Thirteen Diese' Generator Cylinder Heads were visually inspected per Delaval procedure 600-10, Addendum A, Visual Inspection Procedure.

Listed below are the 13 Diesel Generator Cylinder Heads selected by NRC resident for inspection.

Serial Numbers G-95 H-60 E-71 G-53 H-56 G-89 G-19 H-34 G-56 H-11 H-76 H-67 G-52 Results Diesel Generator Head ?/N H-34 has an indication approximately 3/8 inch in length on the machined face bottom port area. This indication is unacceptable in accordance with Delaval Visual Inspection Procedure 600-10, Addendum A paragraph 4.

The indication found on this head was evaluated by the TDI Quality Control Supervisor and Engineering Department. The acceptance-rejection criteria for machined peripheral surfaces is that the surface does not leak under Hydro-test. The indication did not result in a leak. Therefore it was in conformance with the acceptance-rejection criteria established by Engi-neering. This information was provided by TDI Engineering.

d. Attachments Attached to this report are field sketches showing locations of UT thick-ness measurements and one indication as discussed above.
3. Exit Interview At the conclusion of the inspection, an exit interview was held with licensee representatives noted in paragraph 1 on July 29, 1983. No written material was given to the licensee in the course of this inspec-tion.

Hunton & Williams 707 East Main Street P.O. Box 1535 Richmond, Virginia 23212 Re:. Request for Discovery Concerning NRC Region I Inspection Report No.

50-322/83-25

Dear Tim:

Suffolk County believes that the referenced Report may identify significant deficiencies in the "new-style" cylinder heads produced by Delaval and. purchased by LILCo for installa-tion in the Shoreham emergency diesel generators. We have discussed the Report with NRC Staff personnel, and they do not have copies of certain documents upon which the conclusions in the Report are based. Because of the significance of these matters and their relevance to the County's contention regarding the cracking of cylinder heads, we request production of copies of the following on an expedited basis:

1. Documents which establish the acceptance standard (s) for the thickness of the Delaval cylinder head firedeck wall.

Cylinder Head Issue

Dear Alan:

On behalf of Transamerica Delaval Inc., I respond to your outstanding requests for documents in connection with the cylinder. head contention.

With Respect to Your Letter Dated August 23, 1983 Item 1. The acceptance standard was established by Inspection Report 00783 which you already have. That report is the only responsive document.

Item 2. There are no additional documents responsive to this request. Furthermore, we do not believe that there is any engineering disposition dated February 22, 1981 regarding the acceptance standard. Instead, we refer to the engineering disposition, dated February 21, 1981, signed by R. A. Pratt shown on 00783.

Item 3. In response to this item, we enclose Nondestructive Examination Procedure 600-70 entitled " Hydro-static Testing". We direct your attention specifically to ,

paragraph 3.5.4. l With Respect to Your Letter Dated September 14, 1983 Item 1. The QA manual used for the new style cylinder heads is entitled "ASME Quality Assurance Program" which replaced IP500. Copies of both are enclosed.

Item 2. The QA manual used for the old style heads was entitled " Quality Assurance Manual", a copy of which is enclosed. We also enclose copies of I.P. 100 through 600.

. Alan R. Dynner, Esq. January 24, 1984 Item 3. The " objective evidence" referred to in the " comments" section of the Audit Evaluation Form for the audits of October 28-30, 1975, February 23, 1976 and June 18, 1976 refers to evidence in the possession of Stone & Webster Engineering Corporation which serves as a consultant to Lilco.

.Accordingly, such information should be sought from Lilco.

There are no further remaining documents under Item 3 not supplied to you.

Item 4. There are no such documents.

Sincerely yours, a
