AFFIDAVIT OF EDWARD'J. YOUNGL'ING Edward J. Youngling, being duly sworn, deposes and says

, as follows:

a

1. My name is Edward J. Youngling and I am employed by the Long Island Lighting Company (LILCO) as Startup Manager for h9s - the Shoreham Nuclear Power Station. My professional qualifica-

's .

tions have been previously submitted to the Board. As Startup Qs . '

Met Manager, I am responsible for all preoperational test

-- activities. I also coordinate Checkout and Initial Operation w,

{ (C&IO) testing and-preoperational testing. In this role I have G4:w..

7-

. been directly involved in.the testing of Sho'reham's diesel gen-erators and'in resolving related issues that developed during testing. Specifically, I am familiar with the County's conten-Q~ tion'regarding Shoreham's diesel generators.

2. I testified previously in this proceeding-as a member of the LILCO panel.on the Quality Assurance / Quality Control issues. I have also submitted three previous affida-

~vits to the Board regarding Shoreham's diesel generators dated May 16, 1983, June 3, 1983 and July 7, 1983. On June 10, 1983 I appeared before the Board to answer questions regarding

. _ . _ . _ _ . Shoreham's diesel generators.

3. .The purpose of this affidavit is to respond to the:

1y.g, two questions raised by the Board in its, July 20 memorandum am order concerning diesel generators. Before doing so, however, I should report to the Board that LILCO has decided to completi prior to fuel load the planned replacement of the remaining original cylinder heads with the improved, current production

~

model' cylinder heads. As my July 7 affidavit demonstrated, th;

. rigorous preoperational testing of the diesel generators has

'3' confirmed the reliability of the remaining original cylinder

. .f 3 L.- ' ' heads. Nonetheless, LILCO has elected to install the improved

' T>T-;p

. , , current production model cylinder heads to further enhance the up.3%

~ ibih,590 -

reliability of the diesel generators. Although LILCO is o-; ;.ph ',kk concerned over the potential impact of this on fuel load, stepd will be taken to minimize any such impact.

2

4. As noted, this affidavit addresses the two s.

questions raised by the Board in its July 20 memorandum.

. 'i' 4 3M M.3.-

, . a w

First, the Board noted that my April 6 memorandum referred to

" difficulties with five of the twenty-four cylinder heads" whereas previous information presented to the Board discussed three cracked cylinder heads. Second, the Board indicated that my memorandum made it aware of the possibility of lube oil con-tamination due.to water leakage from the cylinder chamber into the lube oil system. This affidavit shows that (a) there have only been three instances of cylinder head cracks which could result in leakage of water into,the cylinder, .

(b) the other cylinder head occurrences referred to in the memorandum did not involve cylinder head cracks which could result in leakage into the cylinder chamber, and (c) the possible lube oil contamination does not affect the reliable

' operation of the diesels, but may require more frequent replacement of engine oil to avoid excessive engine wear.

c .

5. My July 7 affidavit discussed the three cylinder A head cracks found in the original cylinder heads which resulted y

in leakage of water from the jacket water system into the cyl-Jg[

inder chamber. These three 6 racked heads were the subject of SNRC-873.

These three affected cylinder heads were.also 7

discussed in my prior affidavits and at the June 10, 1983 con-ference of the Board and parties. They are the subject of the contention admitted by the Board.

6. My April.6 memorandum to Mr. Rivello states that t

. o LILCO experienced difficulties with five cylinder heads. Three of these~five were the' cylinder heads that were the subject of L

SNRC-873. The other'two cylinder heads were occurrences not

~

involving leakage Tinto the cylinder chsmber. In fact, at the, present time there have been a total cf six such occuirences

. _ ~

SE* ' not involving leakage into the cylinder chamber, All of these-a involved the original heads. Even though all of the original

.. n-:. x ~

- heads will be replaced before fue.1 load,.fpr the. Board's infor-

.d' mation, I will discuss'each of these other occurrences below.

7. Two.of these occurrences were the result of' mechan-ical damage incurred du' ring the removal and reinstallation of

~

the-cylinder-heads for'other maintenance activ;ities.

~

The first was a scrape on the cylinder ~ head gasket" mating' surface which m,

we believe was caused uy the impact df 5 tool or other device.

~

. . ,g n y_ This scrape was detected by LILCO personnel and the head was

- replaced. The second instance involved bolt hole thread damage

[(ffh$ encountered during the removal of exhaust flange bolts. This

..-q.

n%4h? problem was identif,ied and th'e head was replaced, uds : _

8. Two other occurrences resultedin very minor water

' /~ a"in

~

leakage external to the cylinder chamber. The first was the

• result of a pinhole size sand hole on a non-machined, external surface which resu.lted in a very small water leakage onto O

Q ~ 'bbth of these instances was external to the cylinder chamber

and thus .o hadino impact on the ability of the diesels to perform their function. The" amount of leakage in both cases was very

- operation,- both were- corrected by replacing- the cylinder heads.,

[75 dN N 9. The. final two cylinder head occurrences related to

' w, -

' r

' components contained in the cylinder head assembly. In one in=-

stance, a noisy valve was detected by LILCO personnel. The second instance occurred when-the rocker arm shaft bolt failed i,

and' damaged a valve stem. Both situations were remedied by Mi@ m .-:-[ .

s replacing the entire head assembly.

$_6$k'

.-nEN:? - -10. The second. question raised by the Board concerns pr .

the possibility of lube. oil contamination due to water leakage 9yy[szgd '

t - ,

When the engines are not in operation.,

past the piston rings.

gg if there is a.large adount of cylinder head leakage, water

. .3 would overflow the dished piston head and would likely flow Nj@E'

4 occur, would not affect the rapid start capability of the diesels. The concern expressed in my April 6, 1983 memorandu regarding the possible contamination of the lube oil was not concern with the reliable operation of the diesel; rather, IG was a concern relating to maintenance because water contaminc tion of the lube oil system could increase maintenance requig

- - - e .. ments. Under LILCO's preventive maintenance program, diesel generator lube oil quality is sampled on a periodic basis.

q-  :-' Water contamination would require replacement of the oil. Is addition, substantial amounts of water leakage into the lube oil could result in excessive wearing of components over the long term if undetected and uncorrected. It is unlikely, hoe ever, that large amounts of water leakage into the lube oil system via a cracked cylinder head would go undetected. The level of the jacket water system is monitored during operatiE

,j. and standby of the diesels and substantial decreases in watee

, _. inventory would be detected. The barring over procedure, wh$

is no 1cnger necessary because the new heads will be installG e . .+ .

11. Finally, I would like to correct a statement made in my July 7 affidavit. Footnote 2 of paragraph 9 of that af-fidavit mistakenly states that "during low power testing, only two diesel generators are required to be operable under Shoreham Technical Specification S 3.8.1.2." While only two diesel generators are required to be operable under the Shoreham Technical Specifications for loading of fuel, low power testing requires operability of all three diesel genera-If tors.
