6 THE WITNESS:

A.

It is not my practice to base 7

opinions upon comebocy wise 's written report, so I would d

not render an opinion based on someone eloc's report.

X) 9 MR. MILLER:

Q.

If that 's the case, tir. !aylor, 10 could you tell me why it is that enere's presently no 11 intention to look at any cracks in engina blocks other LO 12 than ene blocks at the Shorenam Plant?

13 A.

I said jresently it's not planned to go look at 14 any.

We're working on ene anal sis, and from waat I ha ve

/

})

la seen in the report, chair cracks arc si=ilar to the A6 Shoreham ensinos, so what I plan to co is to determine 17 say tne cracks occar in the shoreham engine and get a 14 very good nandle on vnat the phenomena are, wnst's

that would be pertinent that I don't have yet and a

procably would not be able to reconstruct.

9 Q.

If you were able to obtain that data such as 10 ene load factors, Mr. Taylor, then I gather f rom what 11 you're telling me enat an analysis which would include

)

12 inspection of cracks on other engine blocks coulet prove 13 useful to you; is that correct?

14 A.

That '3 correct.

}

Q.

Mr. Taylor, if you will, look at the third is paragraph of what nas caen marked as Taylor 's 2xhic,it 17 I

We would not address the circumferential cracks g

Q.

Are you througn?

7 A.

Yes.

S Q.

Can you tell say, Mr. Taylor, an entire rie 9

report would not address those latter cracks?

10 A.

Yes, because I am receiving prwasure from 11 management and LILCJ to put a report out so that they can q

12 secte a oialogue with the !!3C.

It's my understanding

2 A.

That summary. cf our computation is stated in e

3 the next sentence which says, " Crack growth rates are 4

small at full load and are negligible below 2625 kw."

5 Q.

What coaut at overload or 3900 kw?

e 6

A.

It's a good question.

I am not sure that we 7

have computed the crack growth rates at 3900.

d Q.

Do you intend to do that?

D 9

A.

Yes.

However, I don ' t want to speculate, but !

10 aelieve ene answer would still be the same.

I the rema tnoer at less load, and a very small number of 2

hours, it wasn't even a complete hour, of 3900 kw.

3 Q.

Now, whet would happen to your analysis, Nr.

4 Taylor, if enat load profile was changed?

5 A.

The estimated crack growth rate is based on the

expoeted numoer of cycles in the operation that you o

7 axpect.

A greater number of hours, greater number of a

ejcles, woulo mean increased crack growtn.
