PREPARED STATEMENT OF HUGH A. MCGOVERN I reside in My name is Hugh Albert McGovern, Jr.

Middletown, Pennsylvania.

I am currently employed by GPU Nuclear Corporation as a Plant Operations Manager for TMI Unit 2.

I served in the United States Navy Nuclear Power Program for six years as a Nuclear Electronics Technician prior to becoming employed by Metropolitan Edison on October 11, 1976 as an Auxiliary Operator A.

I remained as an Auxiliary Operator A until January of 1978, at which time I began a i

that capacity until August 1984, when I became a Plant i

Operations Manager at TMI-2.

This position requires that I

.v maintain aLSenior Reactor Operator's license, which I currently do.

In January 1979, I;was assigned to the "F"

Shift, together with Earl Hemmila and Leonard Germer as Control' Room Operators (Germer was a CRO Trainee), Carl Guthrie as Shift Foreman and Ken Bryan as Shift Supervisor.

Immediately prior to that time, I was assigned to the "A" shift with Ed Frederick and Craig Faust as Control Room Operators, Fred Scheimann as Shift Foreman and Bill Zewe as Shift Supervisor.

As a Control Room Operator, my-general duties consisted of controlling plant parameters and reactor power, manipulating the controls, running required surveillances, overseeing the general operation of the plant, carrying out switching and tagging applications for maintenance and equipment, and directing the work of the Auxiliary Operators.

I was aware, during 1978-1979, that the one gallon per minute (gpm) limit for unidentified leakage was a limiting condition for plant operation.

I was also aware that certain precautionary measures (that is, reduce the leakage to within limits or begin plant shutdown) were required to be taken if unidentified reactor coolant leakage exceeded one gpm for several hours.

Despite certain inaccuracies in the computer program and instruments used to calculate reactor coolant system leakage, I nevertheless believe that the plant could be I was confident operated safely with the information we had.

I) that by paying close attention to the makeup tank level and the Os t

I could have a reasonably good idea of what was pressurizer, going on in the primary plant.

I was aware, during 1978-1979, of certain TMI-2 rules All surveillances mandated by the technical regarding logging.

specifications (such as leak rate tests) had to be logged.

More specifically, we were required to log the starting time I did not always and completion time of any. surveillance test.

comply with that requirement during 1978-1979, however, in large part due to the fact that we were a lot more lax administratively at that time, than we are these days.

I can instructed me to refrain from state, howeser, that no one ever logging the start and completion times of a leak rate test so g3\\)

as to avoid revealing how many tests were started.

During 1978-1979, I interpreted the frequency rule regarding leak rate tests to require that only one good leak rate test every 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> be obtained.

This was the prevailing interpretation of that requirement when I started work in the Unit 2 control room.

As a new CRO, I did not question this practice.

I do not recall seeing Licensee Event Report (LER) 78-62 at the time it was issued.

It was not until after the accident that I became aware of the lesson of that LER, namely, I know now, that we had been misinterpreting the 72-hour rule.

but did not know prior to the accident, that regardless of how often one runs leak rate tests, the TMI-2 operating rules (v~)

'5 e

()

~

require that the action statement be entered whenever

-I am also unidentified leakage in excess of one gpm is found.

more aware now that important safety considerations underlie the 1 gpm limit'for unidentified leakage.

I was familiar with the requirement that exceptions and deficiencies be filed with unsatisfactory surveillance recall ever filing an exception or deficiency tests.

I do not with an unsatisfactory leak rate test, although I now realize that I should have done so.

While I knew that exceptions and deficiencies were applicable to technical specification surveillances, I did not regard the inputting I did to the computer as, performing a technical specification surveillance.

I viewed the computer input work I did in connection

(;-

Rather, with leak rate tests as merely fulfilling an administrative

" paper" requirement.

The standard frequency that leak rate tests were run at TMI-2 was two or three times per shift, although this could vary depending upon what had occurred during the previous shift.

Namely, if the previous shift had obtained a satisfactory leak rate test result, we might conduct only one leak rate test on the next shift, or perhaps none.

During 1978-1979, I was aware of several inaccuracies leak rate tests.

One in the instrumentation used to conduct such inaccuracy was in the computer program used to calculate leak rates.

Specifically, that computer program yielded Ak-)

inaccurate results because it did not make the proper This y; tY temperature compensation for-leakage to the drain tank.

inaccuracy-was a key. reason that I did not believe that the leak rate test was a valid indicator of actual leakage.

The indicated by makeup tank level and actual parameters pressurizer level often conflicted with the results of the computer leak rate test.

During 1978 and early 1979, I was not aware of the phenomenon by which water added to the makeup tank during a leak rate test could enhance the result.

Nor was I aware of the phenomenon by which the amount of a water addition as registered on the strip chart exceeded the actual amount of water added and logged by the operator.

It was not until after the accident that I was informed that adding water to the (O

makeup' tank during a leak rate test could produce an enhanced

_/

result.

The reason for this unawareness was that the existence of this phenomenon regarding water additions was inconsistent with what I had learned as a reactor operator in the Navy.

While I was a control room operator at TMI-2, I never made either unrecorded or under-recorded water additions to the makeup tank during a leak rate test for the purpose of manipulating the test.

Nor did I ever make a " jogged" water addition to the makeup tank to influence the leak rate test result.

I have no personal knowledge that any other operator manipulated leak rate tests through water additions during that time period.

I can also state that to the best.of my knowledge, E'arl Hemmila never made a " jogged" water addition to the makeup tank in an attempt to alter a leak rate tast.

w i

/

During 1978 and early 1979, my shift's approach with

~

We would respect to water additions was basically as follows.

add water routinely to the makeup tank before leak rate tests to better hold the plant steady while the test was being conducted.

We also added water to the makeup tank whenever it approached its low limit, which sometimes occurred during a leak rate test.

We were aware, however, that water additions during leak rate tests should be avoided.

In any event, my shift was aware of the requirement that all water additions to the makeup tank be logged and accounted for, and we complied with that requirement.

Neither I, nor to my knowledge the other CRO's that I

()

worked with, were aware that hydrogen additions to the makeup tank could affect a leak rate test.

I personally never added i

hydrogen to the makeup tank so as to alter a Nor did I ever observe anyone else add hydrogen to the makeup tank during a leak rate test for the purpose of influencing the test result.

As far as I knew at the time, the reason one added hydrogen to the makeup tank was to scavenge oxygen (which is a corrosion agent) from the reactor coolant system.

It was always my practice to log hydrogen additions to the makeup tank.

I was generally aware of the fact that at various times prior to the accident, there were problems with both makeup tank level transmitters.

I cannot specifically recall seeing an out-of-service tag placed on the level transmitter i

O

\\/

selector switch prior to the accident.

l L

r

,c

%~1 As a general rule, I tried to switch the accurate leak rate level transmitter to the computer when running a provided that the other level transmitter (which would

test, give us our level indication in the Control Room) was not so inaccurate that we could not rely on it.

I was able to determine which level transmitter was functioning properly by examining the strip chart level recorder.

Specifically, the good. level transmitter was-the one that exhibited the fewest random oscillations.

There was a time during 1978 and 1979 when we ran some leak rate tests knowing that there were inaccuracies with the makeup tank level instrumentation.

We performed.those tests under such circumstances because we were

(')

compelled by the 72-hour administrative requirement to run leak rate tests.

We recognized that the equipment was malfunctioning, but it was the only instrumentation available to us at the time.

In addition, there were people working on the problem, so it seemed to me that the problem was only temporary.

I remember a period of time when one makeup tank level indicator was being worked on virtually daily.

I can state unequivocally that I never deliberately switched level transmitters during a leak rate test so as to obtain a satisfactory result.

There would be nothing to be gained by doing that.

The deliberate use of an inaccurate level transmitter could just as easily lead to an unsatisfactory leak ate test result as a satisfactory one.

(v~) _

i e

I As a general rule, leak rate test results for which

\\q' unidentified leakage exceeded one gpm were discarded, basically because it was a common practice in the control room to do so.

I was_never informed of a requirement to retain the results of such unsatisfactory tests.

We also discarded leak rate test results more negative than 0.1 gpm.

I personally remember either discarding leak rate test results exceeding 1 gpm, or referring such tests to my shift foreman.

I also recall discarding more leak rate tests than those I kept.

However, I do not recall that Carl Guthrie ever told me to discard leak rate tests exceeding 1 gpm.

I do recall an incident in which the NRC found some unsatisfactory leak rate test results that had not been

(-)

. discarded and brought this to the shift foreman's attention.

However, no one ever instructed me to_ discard unsatisfactory leak rate tests so that the NRC would not see them.

Our standard procedure for measuring identified leakage entailed the shift foreman from time to time sending an auxiliary operator with a graduated cylinder out in the plant to measure leakage.

To the best of my recollection, we made a consistent practice of quantifying identified leakage in this way, and of accounting for it in the unidentified leak rate calculation.

I never felt significant pressure from my shift foreman or shift supervisors to obtain a satisfactory leak rate test result.' Nor do I recall receiving any pressure from those 4 '

p)

L-in-the managerial levels above shift supervisor to obtain a satisfactory leak rate test result.

Occasionally, someone in the control room would say something such as "run another one, we're approaching the clock", but I don't remember any arm twisting or anything like that.

I do not recall it becoming more difficult to obtain an acceptable leak rate test result as the day of the accident approached.

However, there was a lot of leakage from the pressurizer valves just before the accident.

As I stated before, however, we did not regard the We leak rate tests as an accurate indicator of actual leakage.

viewed the obligation to perform leak rate tests as a

( ')

Given that we took perfunctory administrative requirement.

'~

little stock in those tests, why would we go to extremes to manipulate them?

My job is important to me.

I believe that my experience them and about with leak rate tests and legal proceedings about the TMI-2 accident has taught me to be much more scrupulous about procedures.

As Plant Operations Manager at TMI-2, I am very interested in helping the Company complete the cleanup that is well underway.

I believe that I was, and am, a safe operator and that this experience has taught me to be a better operator, and I sincerely hope that the Board will exonerate me from involvement in leak rate test falsification because I did

()

not manipulate leak rate tests.

JUDGE KELLEY:

Mr. McGovern, I have a short 2

statement which provides some context for where we are and 3

the nature of the questions that we'll have for you, which 4

I'll read first and then we'll get into the questions.

5 The Board has been charged by the commission to 6

determine the extent of involvement of individual employees 7

of TMI-2 in '78 and '79 in leak rate test falsification and 8

other improper practices in leak rate testing.

This is your 9

opportunity to state on the record your recollections and 10-perceptions about your involvement in leak rate testing at 11 that time, and to rebut any adverse statements about you by

()

_1:2 other employees or investigators with which you disagree.

13 We have reviewed your prefiled testimony and 14 considered it in light of the record that has already been 15 developed in this proceeding, including some prior statements 16 by you.

We'll have some questions based on.your testimony 17 and on those prior statements that are already in the 18 record.

We may also have questions based upon statements of 19 other employees that they may have made about matters in 20 which you may have been involved, and we may also have 21 questions about assessments that investigators and technical 22 experts have made about your participation in the leak rate 23 activities.

24 As I think you know, there are extensive studies 25 of TMI-2 leak rate procedures that have already been put in ACE-FEDERAL REPORTERS, INC.

the record:

one by Mr. Stier for GPU Nuclear and then 2

another. study by the NRC Staff.

The Stier study includes 3

analyses of every leak rate test conducted at TMI-2 that was 4

retained; that is to say, that wasn't thrown away; and the 5

NRC study includes analyses of every retained test during the 6

last six months of operation.

7 The Board has already heard extensive technical 8

testimony on leak rate testing questions, including testimony 9

elicited by your counsel on numerous particular tests.

In 10 these circumstances, the Board does not propose to review 11 with you each test in which the studies indicate you were

()

12 involved.

We are not going to go through all your tests one 13 by one.

We'll have a few questions about a few particular 14 ones.

15 The studies have been available to you through 16 counsel and you were free to discuss particular tests in your l

17 proposed testimony -- in your prepared testimony, if you 18 chose to do so.

But, as I indicated, we'll have questions on i

19 a few particular tests, not the others.

Apart from that the 20 test analyses are in the record and they will be considered 21 in the light of the entire record, including your testimony 22 today.

23 Reviewing your testimony, Mr. McGovern, and your l

24 prior interviews, particularly your interview with the NRR b

are pretty clear.

We don't propose to go over every 2

significant point, point by point, since there's no need to 3

belabor the obvious.

But we are here, really, to seek

'4 clarification and elaboration on some selected points where 5

we think that is necessary-or desirable.

6 EXAMINATION BY THE BOARD 7

BY JUDGE KELLEY:

8 Q

Let me ask you, first, if you could characterize 9

your general attitude about leak rate tests at-that time.

10 More specifically, did you consider the test as it was 11 working at that time a valid test of actual unidentified 12 leakage?

13 A

No, sir.

I don't think -- I know I didn't really 14 believe that the leak rate test was an accurate indication of 15 plant leakage.

I tended to regard the test as fulfilling an 16 j

administrative requirement more than anything else.

17 Q

In terms of administrative requirement, being that 18 you get a test, as you then understood it, that you get a j

l-19 leak rate test under 1 every 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br />?

20 A

That is correct, sir.

21 Q

So, in running these tests and approving them or E

22 not approving them and throwing them away, was that the basic 23 question, just whether it read less than 17 l

24 A

Yes, sir.

That basically was the criteria I used.

O 25 Q

Did you -- again, I'm speaking a:3 a general I

l ACE-FEDERAL REPORTERS, INC.

mm..

~_ m _,

'/ % 28398.0' i d BRT 3152 l'

matter, and I think this is imp 1'ied from your prior answer --

2.

but, did you really give much serious consideration to

-3 whether the test you were looking at, the.particular test you

.4 were looking at, was a valid test?

5 A

No.

I'm afraid we were' pretty cavalier in our 6

handling-of. leak-rate tests at that time.

7 Q

So, if it was under 1, file it; if it'was over 1, 8

throw it away?

9 A

Yes, sir.

10 Q

There are some tests that you were involved in 11 where there were water additions.

You are not unique in that

()

12 regard.

There were water additions in lots of tests run by i

13 other. people.

But I would like to get a little firmer hold' i

14 than I think I presently have on one aspect of water 15 additions.

'16 I believe it's accurate that the leak rate test 17 procedure did not absolutely prohibit the addition of water 18 during a test but it cautioned against it; is that fair?

19 A

Yes, sir.

I think that's a fair statement.

t 20 Q

So that one was to avoid adding water unless there 21 was some operational need to do so?

l 22 A

Yes, sir.

23 Q

You refer in several places to that l

starting at the top:

2 "During '78 and early79, my shift's approach 3

with respect to water addition was basically as follows.

We 4

would add water routinely to the makeup tank before leak rate 5

tests to better hold the plant steady while the test was 6'

being conducted.

We also.added water to the makeup tank 7

whenever it approached its low limit, which sometimes 8

occurred during a leak rate test."

4 9

What I would like to understand is what you mean 10 by "whenever the makeup tank approached its low limit."

What i

11 was its low limit?

! ()

12 A

I don't recall the specifics.

I believe it was 13 around 70 percent but it has been too long to actually 14 remember what the procedure required.

15 We tried to maintain the makeup tank level in a 16 set band, and if during the course of the operation of that i

17 leak rate operation we reached that set limit, we added water 18 to take us back up to the higher end of the band.

l 19 Q

I'm not sure it's even in the record.

I have 20 heard these references -- at least one other witness has 21 spoken'to what he understood to be a limit and I thought --

22 let me just try this on you -- his recollection, I think, was 23 that the water was to be maintained in a band with a minimum 24 of 60 inches on the makeup chart and a maximum of 85.

In any event, would you agree with that or would 13 you not disagree with that?

I really don't remember what the specifics were.

Yes, sir.

That is correct.

tank for addition to the reactor coolant system.

Getting 2

down towards the low end of that band didn't necessarily mean 3

anything bad was going to happen, but if you were at the low 4

end of that band and had to make a large-scale injection into 5

the reactor coolant system for whatever reason, you ran the 6

risk of running out of water in the makeup tank and the pumps 7

that take at suction of f of the makeup tank are very, very 8

sensitive to a loss of suction.

9 In Unit 1 during their start-up and test phase 10 they lost no less than six pumps, six makeup pumps because of 11 suction problems.

Very, very sensitive to that.

I'm sorry.

Could you --

13 A

I'm sorry.

Maybe I got it out a little fast 14 there.

You were talking about the sensitivity of the 16 pumps in the makeup tank; in other words, they would break?

17 A

Explode is a better word.

18 Q

They won't work anymore?

19 A

No.

Explode is a better word.

They would explode 20 and take out chunks of concrete wall and tear themselves to 21 pieces.

They exploded.

22 Q

Was this because the water level got too low?

23 A

Yes, sir.

They were high speed, high pressure 24 pumps which are very, very sensitive to having an adequate O

25 amount of suction pressure to them.

Very sensitive to that.

-generally maintained and my recollection from looking~at a

~

'2 flot1of others is it's usually up around 60 or 70, something 3

like.that.

4 What I'm trying to get at is, putting to one side 5-an administrative procedure which may.have said:

Keep it at 6-60, if you were going to.run a leak rate test and it is just-7 above 60, let's say, and you are getting a decline of several 8

inches per hour so it's obvious that, all other things being 9

equal, the tank will recede down into the 50s during the 10

. course of the test, is there any safety reason you are aware 11 of that would prevent you from not adding water and letting

()

12 the-thing slip down into the 50s during the test and then 13 bring it back up after the test?

l, 14 A

I don't think you'd get yourself in any real 15 trouble by being at 50 percent.

Most of our limits are relatively conservative.

It would not be something that we would routinely do, I

18 though.

Again, you try to maintain the normal operating l

19 band.

I can't think of anything technical --

20 Q

The adequate suction problem you were referring 21 t o.. the lack of which might destroy a pump, in terms of 22

' inches in the tank, would you think that that would be a 23 concern if there were 30 inches in the tank?

3

~ A Yes, sir, it provides positive suction.

4 Q

Would you think that above 30 the suction problem

?

5 wouldn't be a concern?

6 A

Most likely not unless you had to do a large 7

injection in the reactor coolant system and found yourself in 8

a situation where the amount of water that you had available 9

was used up going into the RCS, and left you with a' low 10 makeup tank level.

11 Q

Well, when you say "large," most of these

12 injections that I see are 100, 200, 300-gallon injections.

13 Is that sort of the typical addition?

14 A

That would be a routine addition..

Is it fair to say, though -- here's how I 22 understand it.

On the one hand the leak rate procedure says 23 try not to add water when you are running a leak rate test.

you have a potential conflict of those two requirements?

2 A

Yes, sir.. Depending upon the amount of leakage 3

from the reactor coolant system to the reactor coolant drain 4

tank, for example; yes, you could easily get the conflict.

5 Q

Would you resolve it in favor of adding the water 6

because the leak rate test provision about water is a 7

precaution rather than a prohibition?

8 A

Yes, sir.

I think that's a fair statement.

It 9

was a "should" and not a "shall."

It was something that you 10 should do, or should avoid doing.

4 11 Q

But I believe you have indicated that your other

()

12 option in this situation is to pump the makeup tank up pretty 13 high before you'even start the test?

14 A

Yes, sir.

You could add water to the makeup tank 15 prior to the start of the test.

16 Q

Could you run it up high enough so that, barring 17 some emergency, there just wouldn't be any need to add water 18 during a test?

19 A

Again, that would depend upon the amount of 20 leakage from the reactor coolant system to the RC drain 21 tank.

And, again, I'm not really that up on what the actual 22 band was, depending upon the amount of water that we could 23 add for that band.

24 Q

Assuming you could pump it up to, say, 80 of the 25 100, if you are going to run a leak rate test you would be ACE-FEDERAL REPORTERS, INC.

during the test unless you had a leak that knocked you down 3

all the way from 80 to 60 in one hour.

OV 12 BY JUDGE KELLEY:

I don't understand, quite frankly, I'm trying to 14 get at why water was ever added to the makeup tank during a 15 leak rate test, and if there are legitimate operational.

16 reasons, fine, that helps explain it.

The idea of 17 maintaining a quantity of water in there we have been 18 exploring.

I'm not suggesting thoroughly, but we are probing 19 it anyway.

But, if you run up -- just to put it to you 20 again, if you raise the level to 80 inches to make sure, you 21 thought, that you wouldn't have to add more water in the next 22 hour2.546296e-4 days <br />0.00611 hours <br />3.637566e-5 weeks <br />8.371e-6 months <br />, wouldn't it have to be a pretty unusual event that 23 would require you to add water with that much water in the 24 makeup tank?

4 Q

How about the case of adding hydrogen to the 5

Let's suppose the panel operator did 6

that, pressurized the makeup tank, and you simply said to 7

him:

Would he likely.

8 volunteer the fact that he had put hydrogen in'the system?

14 there was no reason for the panel operator to think that the 15 hydrogen addition would have any effect on the test?

16 A

of a central concern in this whole proceeding so I would like 4

you to turn to page 37 and 38.

Just look at the bottom of 5

19 A

Yes, sir.

I 20 Q

That particular set of-questions and answers 21 between you and Mr. Russell, again, I think it emphasizes 22 your attitude that the the test was meaningless.

23 your attitude?

plant.

2 Q

Is it fair to ray that the beginning of this asks 3

you about differences between water addition to the batch 4

controller that resulted in a level increase in the makeup 5

tank that was different from the amount of water added -- you 6

go on and indicate on the next page that you may have noticed 7

a difference in the two, at one time or another -- I'm 8

paraphrasing.

9 Is it also fair to say that, in your reading of 10 instruments in connection with leak rate tests, that you were 11 sometimes rather casual about that?

O(_)

12 A

Yes, sir.

I believe that's a very fair statement 13 of the general attitude at that time towards leak rate tests.

14 Q

You say at the conclusion of this section I asked 15 you to look at that you'd just go back and punch the buttons 16 again.

It sounds like a slot machine, in the sense that you 17 keep pulling the crank and sometimes you get a cherry or a 18 bell and sometimes you get lemons.

Does that analogy have 19 any validity in this context?

20 A

I think that the attitude at that time, that 21 probably pretty much sums it up.

I really tend to believe 22 that that's the way that leak rate test was run.

1979, started at 2:53 -- I don't know if that's the afternoon 10 or 2:00 in-the morning.

I guess 2:00 in the morning?

11 A

2:00 in the morning.

()

12 Q

Right.

2:53.

And it showed a net unidentified of 13

.8759.

14 I wanted you to look at the strip chart where the i

15 test is bracketed with the times at the top, just about right 16 in the middle of the strip chart.

The principal point of 17 interest that, if you look at the trace of the strip chart 18 going back to shortly after midnight, there was, apparently, 19 a water addition -- no, shortly after 1:00 a.m.,

it appears 20 to have been a water addition at around 1:00 a.m.,

a little 21 after.

The trace from about 1:15 is, as I read it, down to a 22 little lower than halfway through the leak rate test, it 23 jumps up and down, as they usually do, but there's a straight I

24 line drawn through it which indicates that the decline O

l 25 between 1:15 and around -- let me make the same point I made ACE-FEDERAL REPORTERS, INC.

1 the other day.on a test like this.

2 The actual times as reflected on the computer 3

printout and the times at the bottom on the strip chart don't 4

agree.

That can cause some confusion.

5 A

Yes,-sir.

6 Q

I think we've established pretty much to our i

7 satisfaction for this purpose that the adjustment reflected 8

in.the lines that bracket the-test at the top where it says 9

12:53 to 3:53, there is testimony that the chart was off-by a 10 certain amount at that time, maybe an hour and a half or so.

11 What the analyst would do is-look at something from which

()

12 they were pretty sure about time, which would be, for 13 example, a log entry.

You can-find a log entry that says,'

14 "300 gallons at 12:15."

And you can find that at 1:45 on the 15 strip chart, so you say:

Okay, it's off by an hour and a 16 half.

And that's what we'll say the time is.

That may be to 17 some extent debatable, but in any event, that's the 18 explanation for the effort to reconcile the times.

I don't 19 know that -- well, the time would be significant here for L

20 purposes of what we are going to look at, but I'll assume for l

l:

21 the moment that the analysts' times are accurate.

1 l-22 So, you see the line going down more or less l:

23 evenly from the strip chart time of, what, 1:15?

Are you 24 with me on that?

v 25 A

Yes, sir.

I see where you are looking.

8 through the leak rate test there is an up, it goes.up an inch 9

and a half or so, and then seems to level off.

Do you see 10 that?

11 A

Yes, sir, I see where it deviates from the l ()

12 straight line.

13 Q

And that's really it.

The analysts, NRR analysts, 14 came to'the conclusion, as. indicated by th'e note on'the 15 bottom,.that they think there was a hydrogen addition or 16 water addition at 3:25 and that they read this as having had

}

17 a 2-inch, or 60-gallon effect.

The note goes on to say-that 18 the makeup tank shows the same characteristics as test 120, 19 which we'll look at in a minute.

In this case there's no log 20 entry of either water or hydrogen.

And it is not included in 21 the calculation.

22 Would you agree that there is a consistent offset 23 at the point that is being referred to?

24 A

Well, if there is it's a pretty minor of.fset, 25 sir.

There is an offset from the line that they've drawn.

3-Q There is a change.

It's a question of how much?

4 A

Yes, sir.

5 Q

How much would you say it reflects in terms of 6

inches in the tank?

7 A

Maybe 1 inch.

8 Q

So you'd read that as a 30-gallon effect rather 9

than a 60-gallon effect?

10 A

Yes, sir.

11 Q

Do you have any recollection of this particular 12 test?

i l

13 A

No, sir.

I'm afraid not.

14 Q

Let's take a look at 120, which is not a test run 15 by you.

It's a test -- the operator was Mr. Cooper.

16 Mr. Congdon was on the panel at the time, and Mr. Adams was 17 the shift foreman.

18 I gather they would have immediately preceded you, i

19 I believe that's correct.

Did you typically relieve that 20 crew?

I 21 A

The rotation varied between which crew relieved i

22 which crew, sir.

It's a 6-cycle rotation.

It is not l

23 cons'istent that way.

In this case, yes, we did relieve them.

24 Q

It appears that way.

I'm just looking at the

(

25 logs.

You've got Congdon signing out on the log for 120 at l

2200.

And Hemmila signs in at 2300.

Does that make sense?

2 You say you did relieve him in this case?

3 A

It appears from the records, yes, that we did.

4 Q

Would you look at the strip chart for number 120.

5 A

Yes, sir.

6 Q

In the case of 120 -- as a matter of fact, it 7

shows 121, on the far right, I notice.

So they are both on 8

the same sheet.

Could you look at the offset that occurs 9

during 120, about halfway through?

10 A

Yes, sir.

11 Q

This, as the note shows and the log would show, r~s

(_)

12 this reflected hydrogen addition at that time which produced 13 the result that you see.

In fact, Mr. Congdon testified that 14 what happened there was that they were running an experiment 15 to see-whether the addition of hydrogen would have an effect j

16 on the makeup tank strip chart, such that it would improve, 17 that is to say, make smaller, the leak rate test.

18 So, the log is a hydrogen addition, there are some 19 unreadable words above the strip chart where someone wrote 20 in, " pressurized MUT."

So there's a lot of evidence that 21 this particular test did reflect the hydrogen addition and 22 produced this particular result.

23 Do you think that a comparison -- well, when you 24 compare the offset in 120 with the offset in 121, what 25 observation would you have in that regard?

Do you think they ACE-FEDERAL REPORTERS, INC.

("J BRT T 28398.0-N 3174 1

are comparable?

2 A

The first one, is that offset as marked on 120 3

appears to be quite large compared to the offset on 121.

4 Q

That seems fair.

5 A

The second one is, there is what appears to be a 6

general rising trend on 120 -- it's a small but it's a sharp 7

peak on.121.

8 Q

I agree with you that the offset is not as 9

pronounced.

Could you explain why that offset would occur at 10 all if it were not for either an unrecorded water or hydrogen 11 addition?

r 12 A

Well, no, sir.

I really can't give you any hard 13 facts on why this occurred or what happened in that. time 14 frame.

I don't remember anything specific about that test.

15 Q

I. understand that you wouldn't remember about the 16 test.

I wouldn't expect you to.

I think, in 120, according 17 to Congdon's testimony, it was an experiment.

That might 18 stand out in your mind.

But other tests are run together, I 19 assume.

What I'm asking you for is not so much that specific 20 test, which I accept you might not remember, but whether you 21 can offer any explanation for why that offset would have 22 occurred in 121?

23 A

No other than possibly an inaccuracy in the 24 instrument.

I really can't give you a good one.

Maybe a fg 4

25 little inaccuracy in the logging, too.

The slope, the increase, the amount of deviation.

It 13 doesn't really look to me like hydrogen.

It looks far too small for that.

The temporary change. notice that we are referring' 4-14 to, what did that involve, just briefly?

15 A

Basically, I believe it was an attempt to correct.

16 the computer program for an error that resulted from the 17 change in density of the reactor coolant system when it was 18 leaked through the pressurizer valves to the reactor coolant 19-drain tank; the difference in temperature of those two 20 volumes caused a difference in indicated level and a 21 different amount of water.

But when I read these tests and associated 11 paper, I don't routinely run across a copy of the procedure.

12 Was this piece of paper actually stapled to the test result 13 in.this particular case?

Or did the NRR apparently just put 14 this in as a point of information?

12 MR. BLAKE:

Judge Kelley, would you allow me to?

13 Then we might be able to confirm it.

14 JUDGE KELLEY:

Please do.

15 MR. BLAKE:

The two-page pieces of paper entitled 16

" Temporary Change," the typed form, was a form that was 17 available to individuals at this unit when they saw the need 18 to make, and promptly make, a change in their procedures.

19 They would fill it out, as was done in this case, and they'd 20 get it approved, which you'll see on the second page --

21 evaluated and okayed.

Now put into place it becomes a 22 generic change, applicable thereafter to the implementation 23 of this particular procedure.

leak rates.

And then attached to it you will find the 3

implementation of that TCN, or temporary change, with 4

different figures, depending upon the. parameters that apply 5

to that individual test.

6 So you have the recognition of a need for change 7

in a procedure, its putting into place through this approved 8

temporary change notice, and they implement it with the

entry for that water addition?

I see a log addition at 3:23 2

that says, "added 200 gallons demineralized" --

3

" demineralized water to MUT."

Which would suggest, I would 4

think, that it was a 200-gallon addition.

S' MR. MC BRIDE:

Judge Kelley, if it's all right 6

with_you I'm going to show him the NRR strip chart for the 7

same test because the copy we have here is not very clear.

8 JUDGE KELLEY:

Sure.

9 BY JUDGE KELLEY:

10 Q

The confusion in my_ mind is it says 200 in the 11 log, at 3:23; it says 207 on data sheet 4, and it says 270 in

()

12 the_ interview.

13 A

Yes.

I guess it was a miscopy in the transcript 4

14 or maybe I said 270, meaning 207.

15 Q

Looking at this now does it appear to be either 16 200 or 207?

i l

17 A

Yes, sir, it's right in that area.

18 Q

Can you suggest why there would be the 19 discrepancy, not that it's all that large, between 200 and l

l 20 207?

l l

21,

A Possibly we planned on adding a 200 gallon batch 22

-- this is a suggestion; I really don't specifically l

23 remember.

Possibly we planned on adding a 200 gallon batch

(

24 and it actually went to 207 before the controller timed out.

l l

25 Q

This is from the batch controller?

' k'-)N-BRT 3187 1

A Yes, sir.

2 Q

Does the batch controller -- you set it and it 3

activates a pump and in goes some water.

At the end of that, 4

does it have a, like a speedometer -- odometer,'rather?

5 A

Yes, sir.

More like an odometer.

It has an odometer on it that says 207?,5 6

Q 7

A Yes, sir.

That's basically correct.

It actually 8

opens a valve but the effect is the same.

9 Q

If you would look at the strip chart itself, test 10 150 is marked by lines.

Looking-at the reflection of.the 11 water addition at'about the middle of the test, the line goes l

12 up almost vertically; right?

13 A

Yes, sir.

14 Q

How much water would you say that-reflects?-

15 A

Just using a straight inch conversion it's about 16 240, somewhere in there.

17 Q

Okay.

As I understand the way the instruments 18 work, at the end of the test wher,. you push the button and you I

19 told it that you added 200 pe.lc the computer reads the 20 makeup level indicator; correct?

21 A

Yes, sir.

It did.

22 f Q

So that there would be, as far as the computer 23 knew, 40 more gallons in there than it had been told about in 24 terms of addition; correct?

O) s*

25 A

Just using the straight line indicator, yes.

Give or take a.few gallons.

I grant you that,.

2 certainly.

3

'A-Yes.

4 Q

But, then an amount -- well, an amount of 30 5

gallons on an_ hourly basis would affect the leak rate test by 6

half a gallon per minute; correct?

7 A

That-is correct, sir.

8 Q

So it could have -- would appear to have had, in 9

this case, an effect of half a gallon or more, slightly more, 10 on this' test?

11 A-Not necessarily, sir.

()

-12 Q

No?

Why not?

13 A

Post-accident we became aware, at least I 14 personally became aware of a phenomena with the makeup tank 15 level indication of the compression -- the compression of:the 16 gas in the makeup tank was not accurately reflected-through 17-the level transmitter.

It resulted in an indication higher

-18 than the actual addition.

19 If you'll look at this one, you'll see that that 20 addition was performed in the middle of the leak rate and 21'i that the dropoff occurred somewhere in the last 20 or 25 22 minutes of the leak rate.

It appears that it would have come 23 back down and stablized out.

24 Q

Let me look at it again.

I'm sorry.

Yes, you are 25 right.

The computer takes a picture at the beginning and the l

end, basically.

2 A~

Yes, sir.

It doesn't look at the middle.

3 Q

As I read this, though, it does, indeed, come down 4

but it comes down --'if.it went up eight in the first place 5

as a result of the addition, eight increments -- correct?

It 6

appears to me it came back down about four.

7 A

About 32 gallons, or about the difference between 8

207 and 230, 240.

9 Q

If you take it literally, say it's eight -- that's 10 40 over minus 7.is 33, minus four more inches is -- just 11 about right.

They cancel out.

1) 12 BY JUDGE CARPENTER:

13 Q

Mr. McGovern, I believe you just testified that 14 the apparent offset, vertical offset in terms of increased 15 inventory in the tank that occurred in the middle of this

'16-test was erroneously high?

17 A

I believe that to be so, sir.

f 18 Q

In the ensuing half hour it looks to me that the 19 rate of decline of the inventory is very similar to what it 20 was previously; those two straight lines-are essentially 21 parallel.

For that erroneous overindication to have 22 decreased, wouldn't it be true that those two straight lines 23 would have to have different slopes?

24 A

Yes, sir.

I think if you look at the line right O

25 above the addition point, where the actual bar graph, 70 ACE-FEDERAL REPORTERS, INC.

inches, and it goes to -- I think it peaked at about 74, 2

somewhere in the 74 range -- it looks to me like the first 3

five or 10 minutes are in a slightly steeper slope than the 4

overall trend of that curve.

Again, that's without a 5

straight edge -- I believe that to be the phenomena that we 6

are observing, sir.

7 Q

Mr. McGovern, if we look at the straight lines 8

which the NRR analyst has added, we look at the straight line 9

that's drawn through the portion of the record beginning 15 10 minutes before the initiation of the test, approximately, 11 through a half hour, we see a slope there.

And then after

()

12

.the test was over, about 15 minutes later, water was added 13 and then there is a renewal of the decline in water level 14 with very close to the same slope as preceded the test.

Is 15 that fair?

16 A

I think that's fair, sir.

Yes, sir.

There may be 17 a little difference but it's not much.

18 Q

I grant you that the 20-minute interval that we 19 are talking about, the last 20 minutes, has more l

20 j irregularities than were occurring before and after.

But 21 wouldn't it be reasonable to guess that the best fit line 22 might -- estimating the best fit line might be aided by 23 considering the slope information that is contained in those 24 two other lines?

O 25 A

I think that would, depending on what other plant ACE-FEDERAL REPORTERS, INC.

evolutions were in progress, I think that would probably be 2

fair.

It was probably a general trend.

3 Q

I agree with your qualification.

There's a

-4 tendency to wish that this data had all the data necessary to 5

do the analysis.

I'm well aware that it doesn't.

Thank 6

you.

7 Because, if you draw that line through the last 20 8

minutes that is parallel to the two other lines -- do you 9

have a piece of paper you can use as a straight edge?

10 A

I have a little paper clip.

11 May I offer, sir, if you start from the bottom of lf 12 that first peak following the addition and line that out 13 through to the next water addition, that your trend will be 14 approximately the same as the trend before that one.

15 Q

Right.

So that gets back to my point.

If that 16 overshoot were to dissipate, we'd have to have a line 17 steeper?

18 A

Yes, sir.

You do, for the short period of time 19 immediately prior to that.

20 Q

That makes the record clear; thank you.

21 BY JUDGE KELLEY:

A No.

Not as a general practice.

10n occasion we 2

may have but it wasn't something -.you may have walked over-3 and looked at-it and-you may not have..It wasn't a routine.

4 Q

This does reflect -- by the way, I think'in 5

earlier questioning with you, it does seem to me that an 6

offset persists.. Just ho's much, one can debate, but there is 7

an offset.

It.isn't theEfact that just by going down for a 8

period of time toward the end of the test that it wiped out-9 the whole effect.

The effect, it seems to me, to be still 10 there.

11 Isn't it fair to say that -- not " fair,"-it's a l

12 matter of how the instruments work..

If the makeup tank strip.

g 13 chart were reading, were reflecting a 240 gallon addition-and 14 you entered a 207, that that would then read a leak rate that i

15 was off by 33 gallons?

16 A

Again, no,. sir.

Not necessarily.

l 17 Q

Then tell me why.

l 18 A

If the offset -- the offset was caused by a 19 compression of gas in the makeup tank not being accur'ately i

20 reflected through the reference leg of the makeup tank 21 transfer --

22 Q

You are talking about loop seals.

Yes, sir.

There's evidence that's true, but right now I O

that the makeup tank strip chart is reflecting an addition of 2

240 gallons.

Just assume that.

3 A

At the end of the test, sir?

4 Q

At the end of the test.

And let's not quibble 5

over whether it's 225 or 253.

Let's.just say it does that.

6 Isn't it true that if that is the case, and 207 is 7

put in as the addition, that the computer will produce a 8

result that is off by 33 gallons?

9 A

If it was added as 207 and the indication was 10 240:

Yes.

That is correct.

At the end of the test.

11 Q

Yes.

Right.

)

12 A

Sir, can I kind of follow up on that level 13 transmitter?

I want to explain why it is important, when the 14 addition was done and the effect.

15 Following the accident we discovered this loop 16 seal phenomena, but it is a temporary phenomena.

Once the 17 pressure is registered on the reference leg side of the 18 makeup tank transmitter, it balances out for the overpressure 19 condition, the compression of the gas, and you are indicating 20 a true level again.

That's why it is important that you look 21 at the time of this addition.

The fact that it took place 22 halfway through the leak rate should not have caused any 23 effect on the leak rate itself.

24 Q

Well, wasn't the effect of the -- let's call it t

(f.BRT 3200 1

I didn't know anything about that, and I'm unclear 2

about your reference in your answer to running a test with a 3

hydrogen tank.

4 A

That was a misstatement on my part that was 5

carried over into the transcript.

It was a hydrogen addition 6

to the makeup tank and it referred to the fact that after the 7

accident, during the course of one of the many litigations on 8

this matter, it was brought out that a test was run with a 9

hydrogen addition on the makeup tank and its effect on the 10 level transmitters.

11 Q

Post accident?

()

12 A

Yes, sir.

13 Q

On the subject of adding hydrogen to the makeup 14

. tank we have heard testimony that there was a directive -- I 15 don't believe any tech spec requirement, but a directive that 16 you maintain hydrogen pressure in the makeup tank in a band i

17 between about -- between 15 and 25 psi?

I was i

20 thinking it was in the 30-pound range.

21 Q

The exact -- for the purpose of my question, the 22 exact --

23 A

Again, the answer is yes, there is a band.

1 24 l Q

There was a hydrogen band, you were supposed to gs d

25 maintain it in that band.

Two purposes:

5 addition scavenged oxygen from the makeup water, which-6

_ prohibited corrosion or minimized corrosion in the primary i'

. plant.

8 Q

Was it, as you recall, important from a safety 9

standpoint to maintain that hydrogen band in the makeup 10 tank?

Let's assume for the moment'that the makeup tank is 11-somewhere up over 60 inches.

If that were so, would it be

()

12 important to, nevertheless, have hydrogen pressure in order 13 to have adequate suction to the pumps?

14 A

No, sir.

In that case the more pressing issue 15 would have-been the-chemical contr'1 and corrosion control.

o 16 Q

Was that so pressing that you couldn't allow the 17 hydrogen pressure level to drop below the band for a short c

18 period of time?

Or could you?

19 A

Technically, probably you could have done so.

20 Technically, again, I think there's enough conservatism in 21 our bands that you could have probably allowed it to drop off 22 with no adverse effect for a short period of time.

But, 23 routinely we did not.

Wouldn't it have been possible, if you were about 9

to run a leak rate test, if you wanted to avoid adding 10 hydrogen during tests, wouldn't it have been possible to 11 pressurize the tank before the test?

()

12 A

Yes, sir.

It would have been possible.

13 Q

I mean your typical rate of decline or pressure 14 was not such that you would lose your minimum pressure in the 15 course of an hour, was it?

16 A

As I recall, no.

I don't think you had to.

17 Again, it's a recollection.

18 Q

But your testimony is that you were not aware of 19 any relationship between hydrogen additions and leak rate 20 tests; right?

That is correct, sir.

'l Q'

I just have a'few little questions on general 2

_ things in your testimony, Mr. McGovern.

3 You were a trainee on shift A, and a CRO-on shift 4

F.

Let me ask you, did you. notice any' difference in the way i

5 they operated?

Their attitudes?

Procedures?

Whatever? tit:

Ei seems to:me that what we have been listening to here, every.

7 shift would kind of do things their own way.

And I just 8

wondered if you had noticed this when you changed over?

9 A

Well, there were changes but --'some caused by the i

10 difference in one shift foreman and another.

The changes'I 11 remember most were my role on the shift.

In 1978, as a

()

12 trainee working for two other CROs, well, that-was a.

13 different mode than in 1979 when I was one of the' licensed 14 CRos on the shift.

That's really the biggest thing I 15 remember about it.

Yes, there are always differences between 16 the shifts.

17 Q

From your remark there, would you say that the 18 personality of the shift supervisor had a lot to do with the 19 way the shift operated?

I 20 A

The shift foreman, I would say.

21 Q

Shift foreman?

1 22 A

Yes, sir.

Yes, sir.

I think that's a fair 4

23 statement.

k 24 Q

When you were still a trainee on shift A, C:)

25 Mr. Frederick testified that he kept all of the tests and J

ACE-FEDERAL REPORTERS, INC.

Nationwide Coserage WG336-fM6

gave them to the shift foreman, regardless, whether they were 2

invalid or not.

Mr. Faust testified that he threw away all 3

the tests that he could personally invalidate.

I just 4

wondered where you fit in that little scheme.

What was your 5

way of operating?

Everybody else did whatever they wanted 6

to.

I assume that you did much the same thing.

7 A

Having been trained by those two gentlemen I 8

probably fell halfway in between.

Half of the time the leak 9

rate tests would have been given to the shift foreman and 10 half the time just outright discarded, presuming they were 11 invalid tests.

()

12 Q

Your criterion, was it more like Mr. Faust's?

13 Mr. Frederick didn't seem to have one.

He said if he could 14 personally and to his own satisfaction invalidate the test, 15 he would throw it away.

16 A

Generally I think it even got more haphazard than l

17 that.

I think it was:

It's greater than 1 gpm.

Go run i

18 another test.

i 19 Q

I would like to ask you a little bit about the l

20 LER.

I assume you know the one I'm talking about, 78-62?

21 A

Yes, sir.

22 Q

You state that you don't recall seeing it.

You l

23 really had no knowledge of it, for which a part of the reason l

24 might be that you were in training and not there, in fact, at 25 the time.

But what I was wondering:

You weren't aware of 1

it.

Did anyone on your' shift say-anything about it when you 2

returned?

3 A-No, sir.

Not that I recall.

It was following the 4

. accident and during the previous litigation that it was 5

brought _out the first time.

At that. time I did not remember 6

ever seeing it or hearing anything about it.

7' Q~

So your shift foreman never said a word to you 8

about the changes that supposedly the LER was going to bring 9

about?

-10 A

.No, sir.

Not that I recall.

11 Q

Nor the shift supervisor?

O 12 A

se, sir.

13 Q

You were discussing this change notice with Judge 14 Carpenter.and Judge Kelley.

I understood that that notice 15 came out of what happened at that particular time.

Wasn't it 16 subsequent to the October whatever the date was, test, that 17 brought about the LER?

18 A

I believe it did follow the tests.

But from what 19 I have gathered, recollection, I think it was the mid-March 20 time frame when that change was put in and the LER came out 21 in October of

'78.

That's several months' gap.

22 Q

So there's no particular --

23 A

I don't think so.

A temporary change notice is a 24 rapidly put together change.

There is something wrong with O

25 the grocedure that needs to be corrected now.

One would ACE-FEDERAL REPORTERS, INC.

2 notice would have been in the October time frame.

.g 3

Q One'would_think if they really wanted action on an 4

LER, think would have issued a temporary change notice?-

5

-Would that'be a fair statement?

6 A

Not necessarily.

The LER dealt more with the 7

handling of the action statement and the tech spec _ limits, 8

and really didn't deal with the mechanics of the test, the I

i 9

actual manipulations that were required by the program to get 10 a valid leak rate.

It dealt more with what you did with the 11 leak rates when they'were not valid -- the LER --

()

12 Q

Wouldn't you regard that as being a significant 13 change from what you had been doing before?

14 A

Oh, yes, sir.

It's definitely a significant 15 change.

But it did not require a procedural change, okay?

16 The procedure, the method of actually performing the test was 17 not directly impacted by the LER.

That is a mechanical 18 thing, a software program thing, if you will, that needed 19 correction.

That's what the TCN took care of.

20 The practice of the discarding of the leak rates 21 and the ignoring them, basically, if they were over 1 gpm, 22 that was, more or less was the subject of the LER, and was 23 not directly tied to the mechanics of performing the test.

24 Although I will definitely grant you that if the mechanics of O

25 performing the test had been better, there probably wouldn't ACE-FEDERAL REPORTERS, INC.

1 be this problem now.

2 Q

Well, I'm just trying to figure out why nobody 3

ever heard of any change in the way you did business there 4

after, supposedly, the LER came out and says oh we are going-5 to do all these big things.

Everyone said the same thing:

6 No, doing business to the same old standards.

7 You have no comment?

8

-A No.

That's basically true.

9 Q

Is this the way it went?

10 A

Up until the time of the accident we performed, at 11 least I performed them pretty much the same way.

'( )

12 Q

Very well.

During your training, or any time

+

13 between the time you started and, say, the accident, did 14 anybody ever explain to you what the basic safety 15 implications of doing that leak rate test were?

Or did you f

16 find it out after?

I understand you understand it now.

17 A

Yes, sir.

I really don't remember any specific 18 lectures or training or anyth.ing else on leak rates.

All I 19 remember about performing leak rates and learning how to do 20 them was what I was taught by the CRos.

This is how you 21 punch it out and make the leak rate test come out.

That's 22 what I remember about leak rate training.

t 23 Q

You were talking about the high-speed pumps that 24 transfer water.

Would the reason that they, as you 7,

I would like to be sure about one thing.before I 7

quit here.

Do you -- well, would you like to retract, 8

modify, change, whatever, any of your previous statements 9

that you have made in this affidavit?

10 A

No, sir.

I believe that the statements I have 11 made are, to the best of my recollection, good statements and

()

12 true statements.

13 Q

How about any statement by others that you would 1

14 like to discuss?

15 A

I was.not overly pleased with some of the 16 conclusions from some of the NRR reports.

They have a 17 tendency to be somewhat biased on the outcomes that they 18 provide.

I will grant you that we didn't do things very well 19

-- real badly, as a matter of fact, as far as this particular 20 test was performed.

But the overall black cloud that they

?1 paint was not really indicative of the situation, at least I 22 don't believe so.

I really can't change that one but that's 23 the one I would like to.

Mr. McGovern, just before we broke for lunch I 1

8 asked you to look at NRR test numbers 50, 64 and 74, which'I 9

believe have your signature as the operator, from the point 10 of view of seeing whether.you disagreed with the apparent NRR 11 interpretation of these tests, i. ()

Do you have anything you want to put on the record 15 here that is in contrast to what NRR states?

16 A

I would like to go through 50, for example.

17 Q

I have it in front of me.

18 A

The conclusion that the NRR people reached was 19 that the makeup tank level indicators were switched over to 20 put the bad indicator to the computer and, therefore, cause a 21 problem with the leak rate.

22 Q

It doesn't say it was switched; it says it was 23 used.

A Yes,1 sir.

From looking at the strip chart that'is 2

available for leak rate 50, it is somewhat difficult for me 3

to see a lot of difference between any of the 4

instrumentation.

Neither instrument is overly accurate, is 5

the point I'm trying to raise, there.

6 Q

If you look back to test 49, which precedes test t

7 50, test 49 was at 2140 on the 8th, and the test we are 8

looking at -- do you see test 49's strip chart?

9 A

Yes, sir.

10 Q

Looking at it, and test 50, would you say -- and 11 looking at test 49 for the' period 6:00 p.m. to 10:00 p.m.,

12 there is an oscillator retrace with an amplitude of three or 13 four divisions?

16 oscillator retrace with an amplitude of, perhaps, 10, and in 17 the extreme, 12 divisions?

18 A

Yes, sir.

19 Q

Would I be correct in interpreting that probably 20 the smaller amplitude trace represents one level transmitter 21 and the large amplitude trace represents the other one?

22 A

It could indicate that.

It could indicate a f

l 23 number of other things, too.

I don't know what was going on i

24 in the plant, for example, at that time.

It appears that 25 there was a switch made there.

Q As-far as things going on in the plant, was it 2

common for, oh, temperature, pressure, what have you, 3

associated with power level, to go up and down?

4 A

Depending on what was going on with, for example, 5

feed water -- it could easily cause oscillations throughout 6

the entire primary plant.

7 Q

Wouldn't it affect both level transmitters?

8 A

Yes, sir.

It just depends on which one was 9

indicating on the strip chart.

10 Q

In this case it looks like, if we think one is one 11 level transmitter and one as the other one --

12 A

Yes, sir.

I think that's a fair statement unless 13 something happened in that one period of time where that was 14 settled out or the transient, assuming before the switch was 15 made, was made.

16 Q

Your bottom line on test 50, your point is you 17 don't see how one can, just by looking at test 50 strip chart 18 record, conclude which transmitter was on?

19 A

It is difficult to see how they determined that, 20 yes.

21 Q

Do you have comments about the other two tests?

23 used what was available or was already on the computer.

rather than applied to the computer.

That's conjecture.

2 It's a guess.

3 Q

You, as the signer of this test, you would not be 4

the one to choose which level transmitter you were going to 5

use?

6 A

Nine times out of 10, what you'd really do is say, 7

which level transmitter have you got up?

Or you may not even 8

pay any attention to it at all and run the test, to be 9

perfectly frank about it.

Ideally, obviously, you'd want the 10 better indication for the operator that was trying to control 11 the plant versus for the leak rate.

That's the gentleman

()

12 that's really got a job to do there.

And, again, remember 13 the way that we dealt with leak rate tests, wrongly, but we 14 didn't put a lot of stock in them.

15 Q

Well, I want to come back to just your point of 16 not putting a lot of stock.

In your prefiled, the last 17 paragraph on page 7 you testified you can " state 18 unequivocally that I never deliberately switched the level 19 transmitters during the leak rate test so as to obtain a 20 satisfactory result.

There would be nothing to be gained by 21 doing that.

The deliberate use of inaccurate level 22 transmitter could just as easily lead to an unsatisfactory 23 leak rate test result as a satisfactory one."

24.

Isn't it true that you had the practice of 25 discarding leak rate tests indicating more than 1 gallon per ACE-FEDERAL REPORTERS, INC.

minute and, as a hypothetical, let's suppose the true 2

unidentified leak rate was 1 gallon per minute and every time l

3 you got a 2 you threw it away and every time you got.5 or.3 i

4 you kept it.

5 If the level transmitter were absolutely stable 6

and the plant was at steady state, the probability of getting 7

1 gallon per minute was very high.

But if you had an 8

oscillating transmitter,~ chances are 50/50 that you would get 9

a number bigger than 1 or smaller than 1, as long as the 10 period didn't change very much.

You are stacking the deck by 11 throwing away the highs and buying the lows.

Isn't that

()

12 close to dealing off the bottom of the deck?

13 A

To a degree.

To a degree that would be true, but 14 I don't know that it really would be 50/50.

You already had 15 an installed bias of the actual leakage.

16 Q

Around that central tendency.

Right.

And then you'd have a varying, oscillating 18 trend.

7 A

No.

I would say that was basically a true 8

statement.

We were, again, pretty -- held it in very light 9

esteem.

10 Q

The last few questions have been in very broad 11 termed --

()

12 A

Light esteer.

13 Q

What perplexes me is that the license reads, "In-14 manipulating the controls of the above facilities the 15 licensee shall observe the operating procedures and other 16 conditions specified in the facility license."

Was_there any 17 doubt in your mind that this technical specification was part 18 of the facility license and therefore part of your license?

19 A

I've got to kind of throw that in two parts.

Part 20 A is the actual physical plant conditions.

There was no 21 doubt in my mind that we had to minimize the leakage from the 22 plant and monitor and control that leakage.

Part B is:

Did 23 I view the leak rate test as actually being the necessary 24 part to meet my license requirements?

And the answer to that O

25 has got to be no.

The test had just proven itself to be too ACE-FEDERAL REPORTERS, INC.

invalid over a period of time to be relied on.

2~

Q Why would you generalize that the test,.as they 3

gave it to you, was the way it had to be?

4 A

I'm sorry, sir?

5 0

You are saying the test, as you were instructed in 6

the control room by the other operators, as you found it in 7

the control room, had so many deficiencies that you couldn't 8

take it seriously.

Is that fair?

9 A

That is a fair statement, yes.

10 Q

But, meanwhile, others had judged that it was-11 reasonable to make measurements to a gallon per minute.

They

()

12 didn't say it was easy.

They start off by saying " steady 13 state," which is not easy to come by.

Things like don't add 14 water."

They didn't say it was easy.

But they said:

We 15 l think it is doable.

What is mystifying to me is why, given 16 your identification that this test was really just full of 17 holes, you never filled out an exception and deficiency in 18 accordance with the administrative procedure 1010, which is.

19 one of the procedures by your license that you are required i

(

20 to follow.

You've got freedom to do all kinds of things as 21 long as you follow the stated procedures in particular 22 areas.

23 MR. MC BRIDE:

Judge Carpenter, I'm afraid there's 24 a bit of a legal conclusion in that question about the

We had some technical testimony about the fact.

We 2

went back through the regulations --

3 JUDGE CARPENTER:

I quite agree, Mr. McBride.

I 4

ran the two together and they are different animals.

5 BY JUDGE CARPENTER:

6 Q

But in terms of the emotional climate.is what I'm 7

getting at, not so much a legal thing, the kind of problems 8

here -- did you feel pressure not to identify the test as 9

having a serious deficiency?

10 A

No, sir.

I can't say that I really felt pressured 11 that way.

It was an accepted, known fact.

The test has

()

12 serious deficiencies.

13.

Q But nobody that we have talked to yet ever 14 bothered to document it, even once.

15 A

All I can offer in that is, again, the manner in 16 which we treated a leak rate' test was 180 degrees from the 17 way we treated any other surveillance.

We just didn't treat 18 them like a surveillance.

19,

Q Can you tell me now, reflect for a minute, just 20 why was that?

Why was this the oddball?

21 A

I was thinking about that before and I'll try to 22 give you a few of the thoughts that I have come up with or 23 conclusions I have come up with for why that was.

'l Q

Your thinking about the thinking?

2-A Trying to review and trying to come up with some 3

sort of a logic for that time frame.

They were different in 4

their very nature.

Normally, a tech spec surveillance is set 5

on a scheduled frequency by.a computer system.

It is called 6

a generation maintenance system, GMS system.

It comes out 7

with a little computer-generated sheet that says~ perform it 8

on such and such a date.

Normally, surveillances tested the 9

operability of some piece of equipment.

For example, you 10 would run a decay heat pump on a monthly basis to determine 11 that it developed sufficient flow, sufficient head.

O(_j -

12 This test, this leak rate test, was not run on any 13 set frequency.

It wasn't covered specifically by a GMS 14 computer sheet.

And it didn't really test the operability of 15 anything, as was common with most of the surveillances.

It 16 just was the oddball of the group all the way around.

17 You throw in that along with the problems with the 18 program itself, and it was.just not taken as a tech spec 19 surveillance.

It just wasn't dealt with that way.

20 Q

In the midst of that, I get the sense that if it 21 hadn't been the habit, not a requirement, of running it every 22 shift or at least daily, perhaps you might have viewed it 23 differently?

Possibly.

seriously, don't run the test unless you think you are going 2

to have steady state, perhaps it wouldn't have been run-as 3

frequently?

4 A

That's quite possible, yes.

5 Q

And if you had to carry out the calculations by 6

hand, the whole calculation by hand, maybe you wouldn't have 7

done it so cavalierly?

8 A.

If it was a case where the hand calculation had 9

proven to be reliable; yes.

I think it would have been taken 10 a lot more seriously.

11 Q

Suppose the hand calculation raised questions?

m) 12 A

Then you have to resolve the questions, of course.

13 l

Q But that's what the problem is, of course.

You 14 don't see anybody taking it seriously enough to bother to 15 start a paper trail to cause somebody from technical support 16 to come over and take a look at what was going on.

I really wasn't into that end of the business.

whether you had enough contact to have any opinion -- if you 7

did, do you feel he would be a person that would pick up 8

things like-that?

Again, it's an opinion.

In my opinion, probably 10 not, unless he was specifically brought a board --

11 Q

That's-why I said somebody in technical support.

12 Is that a reasonable guess on my part, that that's the 13 individual that might have come over and straightened it out?

20 BY JUDGE KELLEY:

21 Q

We've got a few follow-up questions from the 22 parties, Mr. McGovern.

The first several are a series of i

23 questions about adding water and under what circumstances.

l 24 Were there reasons, other than for inventory control, that l

25 water might have to have been added, particularly during the ACE-FEDERAL REPORTERS, INC.

202-347-3700 Natuviwide Coverage 800-3 W6M6

(~ '; 28398.0

(_) BRT 3225 1

period when there was a water loss through the code' safety 2

valves on the top of the pressurizer?

3 A

The answer to that is yes, there are other reasons 4

other than just inventory control for adding water.

I can 5

expound on that if you would like?

6 Q

Yes.

Please do.

7 A

Besides just straight inventory control in the 8

makeup tank and the reactor coolant system, the other 9

function that adding water took care of for us was boron 10 concentration, control, and the reactor coolant system.

11 Boron concentration is absolutely critical for controlling r-(,m) 12 the power level of the plant.

Boron is a neutron absorber 13 and tends to shut the plant down.

You tie that in with an 14 automatic rod control scheme and the requirement to maintain 15 a certain band, again the operating band for the rods.

If 16 one was approaching that band limit, one might have to add i

17 demineralized water or borated water to move the rods back 18 into the center of the band.

And that could occur at any 19 ;

time, no matter what the makeup tank level was, i

20 '

Q In my mind, and maybe I don't have the right 21 picture of this, the boron adjustment, boron level 22 adjustments you are talking about here -- by the way, is that 23 what one does in the so-called feed and bleed operation?

24 A

Yes, sir.

That is one method of changing boron V

25 concentration, is a feed and bleed.

ACE-FEDERAL REPORTERS, INC.

202 347.1700 Nationwide Coverage SW336-6M6

-.___,__...m

f' BRT 20398.0 3226 1

Q Okay.

When we use the phrase " inventory control" 2

in the makeup tank, that is a fancy way of saying how much 3

water is in the tank; right?

4 A

Yes, sir.

5 Q

So in my mind, I have heard a lot of testimony 6

about feeds and bleeds, and about boron concentration.

As I 7

understand it, if the boron concentration gets too high or 8

too low, you might add water from the makeup tank in order to 9

bring that into balance or into the range that you want; 10 correct?

11 A

Yes, sir.

You would add water to the makeup tank

()

12 to adjust the makeup tank boron concentration and therefore 13 any RCS boron concentration.

14 Q

But doesn't the water -- you've got water there in 15 the makeup tank; right?

And you want to add water to the 16 RCS, in order to effect boron concentration; right?

So you 17 do that.

And you pump in 200 gallons.

Lo and behold, the 18 tank goes down 200 gallons.

Then you say, as a matter of 19 inventory control, I'll put 200 more gallons in the makeup i

20 tank.

To me they are part and parcel, they are

'.7.ed 21 together.

The question was, are there reasons other than i

22 inventory control why you might have added water?

And then l

l 23 we talked about boron concentration.

Well, to me that's the 24 same thing.

It's all one transaction; isn't that right?

No, sir.

Q It's not?

2 A

It really is two separate functions and that's the 3

key point.

4 Q

I guess I don't understand it, then.

5 A

Yes, sir.

With a slight change in boron 6

concentration in the reactor coolant system, which was a 7

relatively common occurrence during the period of1 time that.

8 we had leaks from the pressurizer, the pressurizer tended to 9

steam the water off and" leave the concentrated boron in the 10 pressurizer.

11 Q

So the boron level got higher?-

p/

12 A

The boron level in the pressurizer got higher.

If s,

13 you did something to cause that water to mix with the-rest of 14 the reactor coolant system, an out-surge from the 15 pressurizer, you would increase the boron concentration in 16 the reactor coolant system.

17 Q

Yes.

Right.

18 A

Increasing the overall concentration would cause 19 the rods to adjust themselves.

They would see that increase 20 in_ poison, and start trying to bring themselves farther out 21 to maintain power level?

22 Q

Right.

23 A

That had to be adjusted for to add demineralized 24 water to bring the rods in, keep them in the band.

25 Q

Demineralized water comes from a source other than ACE-FEDERAL REPORTERS, INC.

the makeup tank?

2 A-No, sir.

It is added to the makeup tank but you 3

-adjusted the boron concentration in the makeup tank so you

-4 could adjust the concentration of the reactor coolant system.

5 Q

Oh, so you are saying -- let's see if I can. follow 6

this.

I'm not a person with a technical background so I'm 7

kind of slow on a lot of these things.

8 You have a certain boron concentration in the 9

makeup tank.

10 A

Yes, sir.

It usually is approximately the same as 11 the reactor coolant system because it's on a continuous, if

'( ')

12 you will, feed and bleed from the reactor coolant system to 13 it and back.

14 Q

So, if you want to dilute the boron concentration-15 in the RC3, you would add water to the makeup tank so as to 16 make that less borated?

17 A

Yes, sir.

That is exactly right.

18 Q

And, unless you did that.you couldn't accomplish 19 your objective of lessening the boron concentr<stion in the i

20 RCS?

21 A

Yes, sir.

That's it.

22 Q

And that would be independent of whatever level 23 was in the makeup tank at that time?

Yes, sir, f

Or do you understand that that was an automatic 3

thing?

4 BY JUDGE KELLEY:

5 Q

Did it. require operator action?

6 A

No, sir.

Again, the makeup tank received water 7

from the reactor coolant system and injected it back into the J

8 reactor coolant system, in a kind of a recirculation-path.

9 You could do things to adjust the flow from the reactor-10 coolant system to the makeup tank or vice versa.
