AFFIDAVIT OF EDWARD J. YOUNGLING l

Edward J. Youngling, being duly sworn, deposes and says as l

follows:

i 1.

My name is Edward J. Youngling and I am employed by Long Island Lighting Company (LILCO) as Startup Manager for the 1

Shoreham Nuclear Power Station.

My professional qualifications I

have been previously submitted to the Board.

As Startup Manager, l

i I am responsible for all preoperational test activities.

I also coordinate Checkout and Initial Operation (C&IO) testing and preoperational testing.

In this role I have been directly l

involved in the testing of Shoreham's diesel generators and in l

l resolving related issues that develop during testing.

Specifically, I am familiar with the matter raised by the County in "Suffolk County Submission o'f Data Regarding Shoreham Diesel Generators," (May 26, 1983).

That submission transmits to the Soard allegations that Diesel Generator 103 has a " cracked engine block" in the area of the camshaft bearing support and : hat "the NRC is not aware of the crack."

R 2.

The purpose of this affidavit is to demonstrate that each of the allegations reported in the County's submittal is false.

Fir,st, there are no cracks in the cylinder block castings.-which will propagate or otherwise adversely affect the life or operation of the engines.

Secondly, although surface l

discontinuities exist in the engine blocks, they were promptly reported to the NRC and, as this Affidavit reflects, they were thoroughly investigated and,.found to be without effect on the strength of the cylinder blocks and without significance to the operation and life of the Shoreham diesel engines.

This Affidavit will first address the lack of significance of these discontinuities that were found in the camshaft bearing supports of the cylinder blocks, and then address the false County allegation that the NRC has not been informed of the indications.

3.

On March 26, 1983, LILCO discovered that the camshaft bearing supports of the three diesel generators had surface discontinuities.

Promptly upon this discovery, a LILCO l

Deficiency Report was issued and Transamerica Delaval, the

-vendor, was contacted.

In addition, as I will discuss below, the NRC Senior Resident Inspector, James C. Higgins, was also promptly notified.

4.

Transamerica Delaval, upon notification, preliminarily concluded that the discontinuities were only normal " surface

imperfections" and advised Stone and Webster Engineering Corpbration-to " dimple" or grind the area of the discontinuities, which is a standa~rd engineering procedure used to evaluate the cause, depth, and significance of discontinuities.

This work was performed under the supervision of Transamerica Delaval's on-site field representatives.

Transamerica Delaval's representatives from its home office in Oakl'and, California then inspected the Shoreham Diesel generator engines on March 31, 1983.

These efforts-and other tests confirmed Transamerica Delaval's preliminary view that the indications were the normal result of the' manufacturing process and are inconsequential to the operation or life'of the engines.

Specifically, they are the result of the differential cooling of the large castings which causes shrinkage discontinuities.

To further substantiate this conclusion, LILCO personnel traveled to Lincoln, Kansas to inspect an essentially identical Delaval diesel generator engine that had in excess of 50,000 operating hours.

In addition, LILCO personnel and LILCO's independent consultant, C.R. Isleib, traveled to Oakland, California, to inspect five as-cast, new f

Delaval cylinder blocks and another cylinder block in an engine on the test stand.

These inspections revealed discontinuities on the 50,000 hour0 days <br />0 hours <br />0 weeks <br />0 months <br /> cylinder block, on the five new cylinder blocks, I

(

and on the test stand engine block that were essentially identical to each other and to those observed in the Shoreham engine blocks.

In total ten engine blocks were inspected,

- - - - ~...

a-

~

4 ib including the three at Shorehamt all of the engine blocks

~

inspected revealed similar discontinuities.

T.hese inspections confirmed the conclusion that the indications are the result of the normal; manufacturing process and not the result of operation and, further, that they are neither susceptible to propagation nor significant to the operation of the diesels or the strength of the cylinder blocks.

The lack of significance of the indications is also demonstr,ated by the fact that, as Transamerica Delaval advised LILCO, Delaval has never experienced a cylinder block failure in the areas where the discontinuities were observed.

5.

In addition to the efforts described above, LILCO

- contracted with C.R.

Isleib and Associates for an independent evaluation of the indications.

C.R.

Isleib is a recognized authority in the field of metallurgy and has over 35 years of experience in the basic metals, iron, and steel industries.

The conclusions of the Isleib analysis agreed with Transamerica L

Delaval conclusions, namely, (1) that the indications originated during the manufacture of the castings in the foundry and not as l

l a result of operating conditions, and (2) that the indications l

will have no effect on the operating performance or life of the I

engine blocks.

6.

In summary, the implication of the County's submission that LILCO decided that the discontinuities were normal merely

.~

a.

. -w.,

.l '. c.

~

l

.j.

'because they could not grind them away is erroneous.

The j

i conclusion that the discontinuities were normal and not signif'icant was based upon a thorough and complete investigation by LILCO in which (1) the cylinder block from a substantially identical engine in service for over 50,000 hours0 days <br />0 hours <br />0 weeks <br />0 months <br /> was examined, 1

I l

(2) new as-cast Delaval cylinder blocks were examined, (3) a test engine block at the Delaval factory was examined, (4) the

(

Shoreham cylinder blocks wexe inspected by the vendor, Transamerica Delaval, and (5) a highly qualified independent

~

consu1 tant examined the Shoreham diesel generator engines, new as-cast Delaval engine blocks, and the test stand engine block.

The conclusions of all this investigation are that the discontinuities are the normal result of the manufacturing process, and that the discontinuities will not propagate or otherwise affect the life or service of the engines.

7.

The second allegation reported in the County's submittal is that the NRC is not aware of the discontinuities.

This l-allegation is totally false.

I personally contacted NRC Senior Resident Inspector James Higgins on or about March 29, 1983 to inform him that an inspection had revealed surface discontinuities.

We have kept him closely informed of our investigation and, in fact, he accompanied the lead diesel test 1

engineer on an inspection of all three cylinder blocks on or about March 30, 1983.

Contrary to the County's submittal, the l
