SUFFOLK COUNTY ' S APPLICATION F R ISEUANCE OF SUBPOENAS Suffolk County hereby requests the Presiding Cfficer of l this Licensing Board to issue subpoenas under 10 C.F.R. S 2.720 to command the production of documents and the testimony by deposition of a panel of employees of the American Bureau of Shipping (" ABS"): Howard Blanding, Vice President, Robert A.
Guiffra, Principal Surveyor - Machinery, End Robert Woytowich, Senior Surveyor. Although representatives of the County con- l tacted ABS shortly af ter learning in mid-May that Transamerica e Delaval, Inc. ("TDI") had attempted to gain approval of the replacement crankshaf ts on the Shoreham diesel generator sets from the ABS, the County was not informed until July 3, 1984 I
that none of these individuals would provide substantive informa-l tion about this matter without being subpoenaed. The County was informed that these individuals would not provide information 8407130216 840709 PDR ADOCK 05000322 4 0 PDR \
because of the posture of this litigation and because they believed that a possible conflict of interest might exist if they were voluntarily to provide the County with information about a submission by one of their clients.
Messrs. Guiffra and Woytowich were the ABS representatives at a meeting on March 14, 1984 among various representatives of TDI, LILCO and Failure Analysis Associates. The attendees discussed the criteria that ABS would use to approve the replace-ment crankshaf ts on the diesel engines at Shoreham, and TDI requested ABS approval of the crankshafts on the basis of their torsional characteristics using ABS's criteria. The testimony of Messrs. Guif fra and Woytowich, both of whom have no apparent interest in the outcome of this litigation, should provide details as to what TDI and LILCO discussed during the meeting.
Subsequent to that meeting, and in connection with attempting to obtain ABS approval of the Shoreham engines, TDI submitted directly to Mr. Giuffra copies of TDI's torsional analysis of the Shoreham engines and other information which is attached as Exhibit 1. /
LILCO now claims that ABS has certified the replacement crankshafts at Shoreham (see LILCC's Response to Suf folk County's Filing Concerning Litigation of Emergency Diesel Generator
- / Although as early as February 29, 1984, the County had requested copies of all correspondence with ABS, these documents were not produced to the County until June 22 and July 5, 1984.
Contentions, June 21, 1984, at 11) on the basis of the informa-tion submitted to ABS by TDI. The alleged certification consists of a letter signed by Mr. Giuffra in response to TDI's submission (see Id., Attachment 4). Based upon the County's review of the documents submitted to ABS by TDI, the County believes that some t
of the documents contain incorrect information. For example, l TDI's forcing function value, "Tn," which is used in the ABS formula, differs significantly from the forcing function found by FaAA to be appropriate. The County has reason to believe that if FaAA's value for the forcing function had been submitted to ABS and were used in the ABS formula, the replacement crank-shafts would not comply with the ABS requirements. Thus, the County believes that the alleged certification by ABS may have been obtained with incorrect data. If the correct data were i
used the crankshafts would not meet ABS requirements. The County seeks to depose these ABS representatives responsible for the alleged certification in order to obtain their views on ,
the certifiability of the crankshaf ts based on information which the County believes is accurate.
In addition, the County believes that the letter from ABS to TDI concerning the replacement crankshafts is not an official ABS certification. The testimony of both Messrs.
Blanding and Giuffra is needed to explain and clarify the significance and effect of this letter. The letter is based
solely upon TDI's submittal to ABS, including the results of strain gauge testing. It is important to ascertain the weight given by ABS to such test data. Mr. Blanding recently informed representatives of the County that, although he would not pro-vide information voluntarily, he would explain the of ficial significance and effect of the alleged certification letter if he were deposed.
The Count ( also requests the production of documents in the custody, control or possession of these individuals and ABS relating to TDI's submission and request for approval of the crankshafts for the Shoreham diesel generator sets: corre-spondence with TDI, notes of conversations or meetings with TDI, calculations made and criteria used by ABS. These documents directly relate to the subject matter on which the individuals
~
are to be deposed.
CONCLUSION For the foregoing reasons, the depositions of Howard Blanding, Robert A. Giuffra and Robert Woytowich will produce information of important relevance to the issues in this pro-ceeding, particularly to the issue of whether or not the replacement crankshaf ts have been certified by ABS. As Messrs.
Blanding, Giuffra and Woytowich will not appear for deposition voluntarily, Stdfolk County requests this Board to issue sub-poenas requiring them to appear, produce documents, and give their depositions in this proceeding.

G:ntlemen:
W2 have your letter of 3 April 1984 submitting copies of the above subject report for our review, and with regard thereto have to advise as follows:
Wa note from the submitted report that the torsional vibration stress in the crank-shaft for the first mode 5 order critical speed (422 RPM) was expected to approach cr exceed that permitted by the Rules for the submitted crankshaft material.
Wa further note from the submitted report that tests were conducted to determine the cetual stresses in the crankshaft, and that these tests indicated a substantial mar-gin of safety against fatigue failure due to torsional vibration.
f B2ced on the submitted test data, and on submitted service experience with similar cngines having similar torsional critical speed arrangements, we advise that we would -
have no objection to the submitted torsional critical speed arrangement for use on dissel generator sets on an ocean going vessel, insofar as our classification require-ments for marine service are concerned.

Report on Crankshaft Torsional Stresses Transamerica Delaval Model DSR-48 Serial No. 74010/12 for Long Island Lighting Company
Dear Mr. Giuffra:
As discussed during the meeting on March 14 in your office between yourselves, Mr. Gene Montgomery of LILCO, Dr. Simon Chen of Power 6 Energy international, Dr. Paul Johnston _of Failure Analysis Associates and myself, I a= sending you four copies of the " Report on Crankshaf t Torsional Stresses" for the three DSR-48 engine generator sets at LILCO's Shoreham plant.
You will note that the report has four sections and contains calculations, test data and operating experience which we consider relevant material to establish the adequacy of these DSR-48 engine generator sets.
The similarity between the DSR-48 referenced in the report are outlined in page 17 and 19. On page 28 are operating hours logged for similar DSR-48. Worthy of note are the Rafha engines which have operated between 5500 hours0.0637 days <br />1.528 hours <br />0.00909 weeks <br />0.00209 months <br /> to 8250 horrs at a load level between 3200 KW and 3300 KW.
Due to the time constrcint on this project, please give this matter your ,
earliest attention. We look forward to receiving your approval.

(
The application of these units are for emergency standby service in the LILCO Shoreham Nuclear Power Plant. These units are rated at 3500 KW and have an overload rating of 3900 KW (111.4%) allowed two hours per day of twenty four hours.
Section One. Torsional Analysis.
A four page introduction is included here, explaining the method and nomenclature used in the torsional cri tical speed analysis.
The mass elastic system in the analysis reflects the piston skirt which has since been superceded. The extra reciprocating weights due to the heavier replacement piston shirt have been evaluated and the change concluded to be negligible. The effect of the 111.4i overload on torsional stress levels are shown in pages 12 to 15 Due to the close proximity of the calculated stresses to the ABS allowable stress, we elected to include Section Two..
Also included in this section are mass elastic system paraceters of other DSR-48 engine generators of identical rating, to establish the similarity of these units, especially from a torsional standpoint.
Section Two. Torsiograph Tests.
Measurements by FaAA/$WEC and TDI are presented here , along with TCl measurements on other DSR-48 engine generators of identical rating and similar mass elastic system. Here again, the intent i s to establish the similiarity between the various DSR-48 engine generators . The stresses evaluated from the torslograph measurements are still in close .

The factor of safety is 1.75 as determined by FaAA, when the effect of shot peening is taken into account and taken to increase the endurance limit by 20%.
g Section Four. Operatine Hours Logged.
There are seventeen engine generator sets of similar configuration and identical rating in Saudi Arabia with considerable operating hours. These similar units are running regularly and generating power today. Worthy of note are the DSR-48 units at Rafha, with 5500 hours0.0637 days <br />1.528 hours <br />0.00909 weeks <br />0.00209 months <br /> at 3200 KW on one unit and 6200 hours0.0718 days <br />1.722 hours <br />0.0103 weeks <br />0.00236 months <br /> at 3300 KW and The similarity of these 8250 hours0.0955 days <br />2.292 hours <br />0.0136 weeks <br />0.00314 months <br /> at 3200 KV for the other two.
units are listed in page 17 Examination of the mass elastic data (I & K) and the torsional natural frequencies (N) listed, will show that the e are no essential differences between LILCO and tne rest of the units. The LILCO units are undergoing performance tests at their Shoreham Nuclear Power Station, the total hours logged at loads of 3500 KW and above, are shown on page 28.
Summary.
Based on the foregoing calculations, test data and operating logs, Transamerica Delaval, Inc considers the adequacy of these DSR-48 ;
engine generator sets to be established for the intended service at the LILCO Shoreham Nuclear Power Station.

TNTRODUCTION I2 TORSIONAL CRITICAL SPEED ANALYSIS _
The engine generator syste= is modeled as a system of mo=ents of inertia interconnected by torsional springs.
The standard procedure is to concentrate all the moment of inertia of each crankthrow, including rod and piston at the corresponding cylinder cenktr position. The moment of inertia per cylinder is obtained by su= ming the moment of inertias of the journal, crankpin, two erankwebs, counterweights (if used), rotating part of connecting rod and the equivalent inertia of the reciprocating parts, (namely the upper end weight of the rod and the piston) .
The moment o5 inertia (I) is calculated by dividing the WK by gravitational acceleration (g). WK2 is obtained by multiplying the weight of the part hy the square of the radius of gyration (K). WK2 therefore, would beunits. in Lb. In.2 or Lb.Ft.2 units and inertia (I) in Lb.In.Sec.2 or Lb.Tt.Sec.2 The inertia values, thus represent the concentrated inertia of the noving parts at each crankthrow.
From our torsional vibration analysis data files, we obtained the appropriate
~alues of inertia or stiffness to make up the.model.
The protedure and notations used in this analysis are explained below.
NATURAL FREOUENCY EUALUATION This is done by Holzer's method. In our Holzer's tabulation, the definitica of the notations are as follows:

The preceeding pages show tne analysis based on the nameplate rating of the engines. To illustrate the changes in amplitudes and stress i levels when operating at 111.4% (3900 KW) or overload condition allowed for two hours per day, we supplemented the analysis with the following
! pages.
The changes in the amplitude. and stress between the two load conditions are reflected in the "T sub n" (T ) values. The following is a listing n
of,the 111.4% T n divided by the 100% nT f r the orders or harmonics calculated. The ratios show the increase in amplitude and stress level l due to the extra load at 111.4% Ioad operation.

On page 19 are measured results by FaAA/5WEC and those by TDI . FaAA's measurement reflects actual peak to peak amplitudes of the overall composi te wavef orm. FaAA also provided the Spuare R,oot of the Sum of ;
i the Spuare? ($PSS), which would be comparable to the overall amplitudes measured by TDI using the Bell & Hov. ell C.E.C. Vibration Meter. Also ,
included in page lo are test . 2sults of other 05R-48 engine generator sets with sinitar mass elastic system end of identical ratin9 It can be readily observed that the Fourth Order amplitudes measured by FaAA/5WEC on the subject crankshaf t are similar to values measured by TDI on similar 05R-48 engine generators. Aisc the FaAA/5WEC SRSS aralitudes and T01 measured overall amplitudes are very siri tar . It may also be noted here that the Bell & Powell C.E.C. I ,strumentation used by TDI is v.idely used in the trade and although the measurement do not represent a theoretically correct peak to peak amplitude It does however provide a common method in measuring the combined ef fects of the various harmonics.
On page 20, reference is made to the approval of crankshaf t drawing 03-310-05-AC, as well as the corresponding ABS forging report number and physical properties. For comparison of the actual crankshaft minimum tensile property between LILCO, Kousheng and Rafho, we have included the values for the latter two. e On page 21, allowable stress levels due to single harmonic and overall are calculated using 1982 and current 1996 ABS Rules.

Submittal to the American Bureau of Shipping for the DSR-4813-Inch by 12-Inch Replacement Crankshafts Fatigue Analysis of the Replacement Crankshafts The factor of safety 'against fatigue failure in the replacement (12-inch crank pins) crankshafts is calculated in this section. The stress levels in the replacement crankshaf ts are con $puted from strain gage test data. The endurance limit is first established for the failed cranksnafts (11-inch crank pins) from strain gage test data. This endurance limit is then scaled to account for the higher ultimate tensile strength of the replacement crankshaft. The effect of shot peening the replacement crankshafts prevides an additional margin against fatigue failure.
Stresses in Replacement Cranksnafts The replacement crankshaft was instrumented with strain gages in the fillet locations of crank pins 5 and 7 and tested under operational conditions at botn 3500 kW (100% rated load) and 3S00 kW (1094 rated load), 650 RPM synchronous speed, The highest stresses were measured in r. rank pin 5. A dynamic model of the crankshaft confi rms that this pin undergoes the greatest range of torque. Three-dimensional finite element models of a quarter crank throw show that the strain gage rosette was placed in the location of highest stress, both within the fillet and around the crank pin. The following strains were
- measured at 3500 kW:
Strain Gage Maximum Minimum 5-1 (compression) -195 uc 288 ue 5-2 (bending) 695 ue -410 uc 5-3 (tension) 737 uc -610 ue PRJ:5-03310A-d/slw 3/27/84
I i
To account for the simultaneous effects of shear and bending, the 4
stress state is represented by equivalent stresses using Sine's method [1].
For a biaxial stress state, the equivalent alternating stress, Sqa, and equi-valent mean stress, Sqm, are given by:
I S,=(Sf-S q
5 + Sj )U and Sq ,= 5,3 +S m2 where 5,3 and S a2 are the alternating components of principal stress, and Sm ,
and S m2 are the mean components of principal stress. From the test report
[2], the equivalent alternating stress, Sqa, and equivalent mean stress, 57, on crank pin 5 were calculated to be: l i
Sqa = 24.6 Asi Sq m = 4.8 ksi Equivalent stresses, S qa and S qm, are those alternating and mean uniarial stresses that can be expected to give the same life as the given multiaxial stresses.
Endurance Limit for Failed Crankshaf t ,
The failed crankshaft was instrumented with strain gages in the fillet location of crank pin 5. This fillet on the f ailed crankshaft had previously experienced a fatigue crack during performance testing. After the test, the l three-dimensional finite element models of a quarter crank throw showed that l the strain gage location on the failed crankshaft was placed close to the l t
location of maximum stress. The measured stress range is used to establish ,
the endurance limit in this analysis as a conservative assumption, although l the actual maximum stress range is revealed by the finite element model to be about 15 percent higher at a nearby location. From the test report (3), the l following strains were measured at 3500 kW: ;
l t ,
f PRJ:5-03310A-d/slw 3/27/84 l i
Strain Gage At Maximum Torcue At Minimum Toraue :
5-1 (tension) 1118 uc -707 uc 5-2 (ben n ng) 773 uc -459 uc 5-3 (comp ression) -389 uc 265 uc l
The equivalent alternating stress, Sqa, and equivalent mean stress, Sqn, were calculated to be:
Sqa = 33.7 ksi S
qm = 10.9 ksi -.
From the test logs, it was determined that the shaft had experienced 273 hours0.00316 days <br />0.0758 hours <br />4.513889e-4 weeks <br />1.038765e-4 months <br /> at equal to or greater than 100% load, or about 4 x 106 cycles. By using (
Miner's rule and typical slopes of SN curves, it was determined that the encurance limit for this mean stress was 32.4 ksi. The ultimate tensile strength for these crankshaf ts averaged 96 ksi. A line representing this endurance limit is shown on the Goodman diagram [4] in Figure 3.1.
Tnis line is bounded by two lines showing the endurance limit for full scale crankshafts based on other test data [5].
Endurance Limit for Replacement Crankshaf ts The replacement crankshafts have a minimum tested ultimate tensile strength of 103 ksi. The endurance limit scales linearly with ultimate ten-sile strength. On this basis, the endurance limit for the replacement crankshaft is shown in Figure 3 1.
The fillet regions of the replacement crankshafts have been shot peened. The effect of shot peening may produce widely differing increases in fatigue endurance limit; however, a conservative minimal value of this in-crease is 207, [6]. The endurance limit for the replacement crankshafts, including the effect of shot peening, is shown in Figure 3.1.
1 PRJ:5-03310A-d/slw 3/27/84
i Factor of Safety Against Fatigue Failure The factor of safety against fatigue failure of the replacement crank- [
shaf ts is 1.48 when the effect of shot peening is not considered, and is 1.75 when the effect of shot peening is assumed to increase the endurance limit by :
20%;
At 3800 kW, the strain gage test data [1] on the replacement crankshaf t I
shows that the stress level is 4% greater than it is at 3500 kW. At 3900 kW it would be about 5% greater than it is at 3500 kW. Thus, there is an ade-quate safety margin against fatigue failure at the specified diesel generator j set two-hour-per-24-hour period rating of 3900 kW. f I

Dear Mr. Giuffra:
Relative to the conversation you had with Roland Yang on the subject of updating existing approved drawings for the DMR/DSR-48 engine.
I have prepared a list previously approved drawings for DMR-48/
DSR-48. We are sending you four (4) copies of drawisgs, which have been modified since the previous approval in 1976.
In the listing, I have describe the details of changes or modifications, with the current drawing numbers. Those marked "Same" are unchanged.
We appreciate your help in this matter and look forward to obtaining the approved drawings. If I can be of any assistance, do not hesitate to call me.
Youre truly, i
