1. Please state your name, business affiliation and

address.

A. My name is Dr. Paul R. Johnston. I am employed by

Failure Analysis Associates, 2225 East Bayshore Road, Palo

Alto, California 94303.jI

2. Have you previously testified in this proceeding?I

|A. Yes. My resume and professional qualifications

! have been previously submitted in this proceeding.I

Ij 3. Dr. Johnston, are the measured stresses in the

I Shoreham replacement crankshafts linear in their progressiong

I from 2000 MW to 3800 KW?I

| A. Yes. The stresses in the crankshaft increase| linearly with increase in load. The stresses in the crankshaft9

| have been determined from the dynamic strain gauge test of EDG

|t 103 in January 1984 at loads of 1750, 2700, 2800, 3500, and

3800 KW. Results of this test are shown in LILCO Exhibit C-16

| previously admitted in this proceeding. Specifically, the

||

relationship between load and stress or strain is shown in )

iI Figures B-1 through B-6 of this exhibit. These figures show a |

| |

| linear increase of stress with load. Generally, if the load

| .

changes by a given percentage, it can be seen that the stress

or strain changes by a slightly smaller percentage.

4. Dr. Johnston, in response to several of Mr. Dynner'sBush indicated that one ofquestions on cross-examination, Dr.

the stresses measured upon the Shoreham replacement crankshaft

was tensile stress, which Dr. Bush indicated was measured at

29,800 psi (in a Stone & Webster report) and was not utilized

in his analysis. Do you agree with this?The strain gauge measurements on the EDG 103A. No.

crankshaft capture the eifect of all stresses on the

crankshaft. These stresses include torsional, bending, and

tensile stresses (I prefer to refer to the tensile stresses asThe stra'in gauge measurements were reduced toaxial stresses).

testified that it was these stresses that were used in hisfatigue analysis.

The stress values quoted by Dr. Bush in response to

a question from Judge Ferguson were taken from LILCO Exhibit

C-16, page B-5 (the Stone & Webster report referred to by Dr.-|

'l The major principal stress of 29,800 psi referred to byBush).

!! Dr. Bush is not an axial stress but simply a combination of the1 The stresses that Dr. Bush quoted

This stress state is the one used by Failure Analysis

Associates in LILCO Exhibit C-17 and thes is the stress state

used by Dr. Bush. Simply put, this means that Dr. Bush did not

ignore any stresses and actually used the appropriate stresses

in his fatigue analysis.
