25 MR. FISKE:

526 Zochann G

1 Q

Mr. Zechman, you realize that you continue

()

under oath this morning?

3 A

Yes, I do all day today, certainly.

4 Q

In some testimony that you gave at the end of the day yesterday, you said that operators had been 6

trained to look at, among other things, pressurizer 7

level in order to terminate high pressure injection.

8 MR. MacDONALD:

Are you asking what he g

tes tified?

10 MR. FISKE:

It is a preliminary question.

11 A

That wasn't all inclusive.

That was one of 12 the things, we maintained pressure and level of high pressure injection.

That's not all inclusive.

14 g

I don't think you lis tened to the question.

15 question was,didn't you testify yesterday that The 16 in determining whether to terminate high pressure 17 the injection after it had come on in the course of 18 transient, one of the things the operators would do 19 would be to look at pressurizer level?

20 A

One of the things we did was look at pressurizer level but what I am saying is that that is 22 not the point of termination of high pressure injection.

23 Q

The question was wasn't it one of the Os 24 things that the operators looked at?

25 t

527 l

Zschaan 4

1

/~h A

To try to maintain level.

2 Q

Right.

Didn't you testify yesterday that 3

you believed that the pressurizer level would be an 4

indication of the inventory in the system?

A That's correct.

6 Q

In the training that you did in the 7

Training Department at Met Ed, did you tell the 8

operators that they could assume that pressurizer 9

level was, in fact, an accurate indication of system 10 inventory?

11 MR. MacDONALD:

You are talking prior to 12 the accident?

r-(]/

13 MR. FISKE:

Yes.

14 Prior to the accident our training program A

15 reflected the fact that to maintain pressurizer level 16 insured inventory in the RC, proper inventory in the 17 right RC, yes.

18 And that looking at pressurizer level would Q

19 te11the operators accurately what the system inventory 20 was?

21 O

That is what our training at both B&W and A

22 our Met Ed program indicated.

23 Q

Did you feel that as head of the Training 24 Department that it would have been important for the Q(._ /

25 i

4

I 528 Z3chnon 5

1 b

\\/

2 operators to know in the training that you gave them at Met Ed if there were circumstances under which in 3

of the transient pressurizer level was not 4

the course G

an accurate indication of system inventory?

5 6

A That did not occur to me based on our 7

training.

8 Q

I think you have testified several times not aware prior to the accident 9

yes te rday that you were level of any circumstances under which pressurizer 10 11 would not be an accurate indication of system inventory.

MR. MacDONALD:

I object.

I have no problem--

12 if you think you have to clarify something but j

13 going back and having him trying to remember what 14 tes tified yesterday is very dif ficult.

he 15 MR. FISKE:

I will rephrase it.

16 17 Q

Is it correct that in the training you gave told the operators that pressurizer 18 at Met Ed, you level was an important indication of system inventory?

1 19 A

In the training of our operators both at 20 21 Met Ed and at the simulator, level in the pressurizer ggg told them 22 was focused on as long as we maintained -- we an indication long as we maintained level that was 23 as of satisfactory inventory.

(~

24 I

I think you said yesterday that you were not Q

25 I

O 2

aware prior to the accident of any situation in which Pressurizer level had increased while pressure was 3

decreasing.

4 MR. MacDONALD:

Are you asking that again?

G 5

MR. FISKE:

I am stating that as a 6

Preliminary statement and I will ask you today 7

8 as a fresh question, doesn't that, in fact,raflect your testimony?

9 10 A

Prior to the accident?

11 Q

Yes.

12 A

I said I could not recollect at this time in our training that I observed pressurizer 13 any time decreasing during normal 14 level increasing or pressure 15 operations.

to the 16 Q

Is it your testimony that prior there could be 17 accident that you didn' t understand that circumstances under which pressure dropped creating 18 saturation or boiling and in that situation pressurizer 19 level would increase?

2C A

Never occurred to me prior to the accident.

f lll 21 22 Q

To your knowledge, did anyone in the the accident?

in this case by Ronald J. Toole, an employee of GPU, 3

and let me ask you preliminarily, did you know Ronald J.

Q Mr.

8 in July of 1981 and I would like to read just several from his deposition.

If you want 9

questions and answers I am reading from 10 to look at them, you are welcome.

" Question:

Was it your belief in 13 I

(~)

September of 1977 that a rise in pressurizer level

(/

13 accompanied by a simultaneous drop in reactor coolant 14 could not occur when reactor coolant pumps 15 pressure fuel in the core of were in operation and there was 16 17 the plant?

"Mr.

Glassman:

" Answer:

I don' t remember.

I 19

" Question:

Was it your understanding in 20 September of 1977 that the formation of voids in the 21 j

(l) system in the reactor coolant system would displace

~

22 inventory which would then migrate to the pressurizer?

23

" Answer:

I believe I testified yesterday

['N 24

\\_)

that if voids were to occur in one place in the vessel 25 o

I 532 Zechman 1

O other than the pressurizer you would force liquid into 2

3 the pre-surizer level.

4

" Question:

This was an understanding that O

you had in September of 19777 5

don't remember if I did or didn't.

6

" Answer:

I 7

" Question:

Is this an understanding you 8

had before the accident at Three Mile Island in March 9

19797 don' t know that I ever addressed 10

" Answer:

I 11 it that way, but I assume that I knew if I put a s team that it 12 bubble in one place and raised the pressure, 13 would go on someplace else because th a t is, in fact, 14 what you did with the pressurizer.

l Did Mr. Toole ever communicate to you, or 15 Q

his in the Training Department, 16 to your knowledge anyone 17 understanding of the effect of voids in the system on 18 level in the pressurizer as he described it in the 19 testimony that I just read to you?

T personally do not recall ever discussing 20 A

21 that subject with Mr. Toole.

ll) testified previously, Mr. Zechman, 22 Q

You have 23 and this is a preliminary question, that you understood that if pressure dropped in the course of a transient

Q You are

as it is used with term " saturation,"are you not, 6

l respect to nuclear reactors?

7 A

I understand the term " saturation" in terms 8

trained, whether it was the pressurizer of what we were 9

or the steam generator.

10 isn't saturation what Q

In layman's terms, 11 occurs when the water in the reactor coolant system 12 to steam?

or in the pressurizer turns 13 refers Saturation -- the term " saturation" A

14 at which water to the point -- at a given temperature 15 will turn to steam.

16 Q

That is the same concept, is it not, to 17 have the water boil?

18 A

That is the same concept as the water 19 changes phases.and boils.

I have no 7

idea what -- they never relayed that to me, to the 8

during the period of time you were in charge of it in L_

13 training the" operators on how to deal with transient I

14 conditions, is this the kind of information you would 15 like to have had?

16 MR. MacDONALD:

Objection. Purely 17 speculation.

18 MR. FISKE:

It is something he has no 19 recollection of ever receiving and you are 20 asking questions based on that.

21 9

If it hadn't occurred to me prior to the A

22 accident, it would be pure speculation at this point.

information as to whether or not

(.,/

2 be given accurate 3

the pressurizer level could be relied upon as an indication of system inventory?

4 accurate O

5 A

Certainly it was important to me that we 6

were,and we were assured that it was.

That was our 7

understanding.

8 Q

Neither Mr. Floyd nor Mr. Toole ever told 9

you anything that changed that understanding?

10 A

Not to the best of my recollection.

11 Q

Earlier in this deposition, Mr. Zechman, we showed you a document which has been marked as 12 13' B&W 558, which is a chapter called " Core Performance"

()

14 from the publication

  • Nuclear Power Preparatory Training, l

from the l

which was purchased by Metropolitan Edison 15 16 NUS Corporation.

17 Let me just show you that again.

Do you 18 have that in front of you?

19 A

Yes, I do.

4-20.

l 20 Q

I would like you to turn to page 21 Do you have that in front of you?

gg 22 A

I have that page in front of me.

i 23 Q

I would like to read you a paragraph about two-thirds of the way down the page from this document.

Do you see those three sentences from that g

portion of the Met Ed training materials?

10 A

I see that sentence.

2 I can't speak for other people in my A

3 depar tment.

I can say that I don't personally recall 4

ever seeing that paragraph in the manual or being used.

g Are you familiar with something called Q

6 hot functional testing at a nuclear power plant?

7 A

Yes, I am.

8 Q

Could you explain in as few words as you 9

doing it accurately, what hot functional testing

can, 10 is?

11 A

Hot functional testing is simply heating 12 up the system and running the system and doing testing

(~}

13 v

under those conditions.

14 Were you aware in September of 1977 that Q

15 to functional testing was going on with respect hot 16 Unit 27 17 recall we went.through a period of hot A

I 18 functional testing.

I don't recall th e exact timing.

19 Q

Did it come to your attention that in the 20 course of that hot functional testing a situation had 21 11, been experienced where steam had been generated in the 22 hot legs and pressurizer level increased?

23 I have no recollection of that.

A 24 n-Q To make it more complete, did it come to x-25

542 h

Zochcon 1

~}

your attention that during the course of hot functional 2

testing a situation had developed where pressure 3

decreased, saturation was caused in the hot legs, and 4

pressurizer level increased resulting in a situation 9

5 where pressurizer level rose while pressure was down 6

as a result of saturation?

7 A

I have no personal recollection of that.

8 Q

Let me show you a document which has 9

previously been marked as B&W 175 which are pages from 10 the GPU start-up test log book.

11

.Do you have that in front of you?

12 A

Yes.

13

()

Q Is it correct that the GPU start-up test 14 that log book was designed to record in a log events 15 occurred during hot functional testing?

16 A

I never personally used the log book or 17 was any part of those tests.

So looking at this is new 18 to me.

19 Q

Let me just show you -- ask you to tura 20 to what is the fourth page of this document which hhs at the top of the page, " John C. Ulrich 9/8/77."

MR. MacDONALD:

I will let him answer.

I

just want to object to the form of the question.

3 I have no recollection of that kind of a A

4 discussion at this time.

g Q

You have no recollection of either Mr.

6 is that Miller or Mr. O'Hanlon telling you that; 7

correct?

8 A

That's correct.

9 Q

Have you learned at any time up until today 10 information that Mr. Miller or Mr. O'Hanlon reported that 11 to anybody else in the Training Department?

12 A

No, I do not.

O-13 Q

Have you learned at any time up until today 14 that Mr. Miller or Mr. O'Hanlon gave the Training 15 Dopartment any of the information that they had 16 received from Mr. Murray at that Users Group meeting?

17 I have no recollection of that information A

18 at this time.

19 Q

Did it ever come to your attention, Mr.

20 Zechman, prior to the Three Mile Island accident that 21 (Ik there had been a transient at Unit 2 in March 1978 22 involving a failed open PORV in which during the course 23 of the transient pressure decreased and pressurizer level increased?

Is it correct in pressurizer information concerning an increase 6

that level and a decrease in pressure during the course of 7

12 2

that there was another transient at Unit accident

()

in April 1978 with respect to an analysis of Met Ed I

14 after the transient concluded that because of steam i

f 15 formation in the reactor coolant system, bubble 16 pressurizer level had been held up?

17 I have no recollection of that.

MR. MacDONALD:

Based on that.

3 MR. FISKE:

Listen to the question again.

4 O

(Question read) 5 I have no recollection at this time.

6 A

7 Q

I take it it would also be your testimony that you have no recollection of learning any 8

of information from that transient about the effect 9

saturation on pressurizer level?

10 11 A

Since I cannot recollect that one, certainly I can't associate it with level.

12 13 g

Is it your tes timony, Mr. Zechman, that notwithstanding all of the information which has been 14 to your attention in the last hour of this 15 brought or known deposition concerning information available 16 to various people within the Met Ed organization 17 18 concerning the fact that a decrease in pressure'can an increase saturation which in turn can cause 19 cause 20 in pressurizer level resulting in a situation where 21 Pressurizer level is increasing while pressure is lll 22 decreasing, that at no time did that concept get communicated or known to the Training Department?

23 MR. MacDONALD: I' object to the form of

()

24 25 the question.

I think there are assumptions f

'h

563 Zechman 1

can answer to the best of his understanding.

but he 3

4 A

Again, I will speak for myself.

I have no 9

recollection of that being relayed to us.

I cannot 5

6 speak for everyone in my Training Department.

7 Q

Am I correct in understanding that notwithstanding the existence of the information in 8

that it has been presented in the the various forms 9

last hour of this deposition, the Training Department 10 Island continued right up to the day of the Three Mile 11 to train operators that pressurizer level was 12 accident indication of under all circumstances an accurate i

13 inventory level in the system?

14 MR. MacDONALD:

I object to the form, but 15 16 he can answer.

17 A

Would you repeat it?

(Question read) 18 19 A

To the best of my recollection, the Training at Met Ed and at the simulator informed 20 Department the pressurizer the operators that maintaining level in lll 21 assured inventory in the RCS system.

22 procedure at Met Ed under 23 g

was there a Toole or Mr. Miller or Mr.

f which Mr. Floyd or Mr.

24

(

O'Hanlon would communicate to B&W to understand that 25 l

{

H

564 20choon 1

O they had information with respect to the f act that 2

an accurate indication of pressurizer level was not 3

system inventory in a situation where a drop in 4

G Pressure had caused saturation?

5 Anything I would say about what their A

6 communications were would be speculation on my part.

7 You don't know of any regular procedure 8

Q at Met Ed that would have led them to communicate that 9

communicate it to kind of information to B&W and not 10 their Training Department in their own organization?

11 Let me see if I understand that question 12 A

correctly.

13 saying is was there a procedure What you are 14 they would relay any information they knew such that 15 that to someone else but not the Training 16 about 17 Department?

18 Q

Yes.

of any such procedure.

A I am not aware 19 Q

Was there a procedure at Met Ed whereby 20 3

log books relating to hot functiona information from the 21 ll testing would be related to B&W but not to the Training 22 23 Department at Met Ed?

Again, you are asking me what somebody else A

24 it is hard for me to speak would do and I don't know --

25 i

1

-,r-,--.,.n.-

I 565 Zachsen 1

Oiv 2

for what they would do.

3 Q

Your understanding, I take it, at the time that if you were head of the Training Department was 4

6 in the Met Ed organization received information 5

anyone which would be useful to the operators in preventing 6

7 a major transient, that that information would be at Met Ed; is communicated to the Training Department 8

9 that right?

10 A

I am saying that it was normal policy that 11 things the plant superintendent, licensing or vice it was normal policy to 12 president wanted us to know, 13 send us that information.

There certainly was not a policy that you 14 Q

were aware of as head of the Training Department where 15 that information would be communicated to B&W but not 16 to your own Training Department?

17 of.

18 A

Not that I am personally' aware 19 Q

Was there any procedure at Met Ed where transient on March 28, information concerning either the 20 21 1979 involving the open PORV, the transient in April lll involving a cooldown resulting from failed 22 of 1978 or the transient in November 23 open steam relief valves, not to Me t 1978 would be communicated to B&W but 24 of

2 A

I am not aware of them supplying B&W 3

information that they felt that we should know and 4

not supply us with.

I am not implying by that, lll I saw it.

5 6

Q Just one last question.

Is it fair to 7

say, Mr. Zechman, that you have no basis as you sit 8

here today f or telling us that B&W was aware of what 9

Mr. Floyd new, what Mr. O'Hanlon knew what Mr. Miller 10 knew and what Mr. Toole knew concerning the impact of --

11 concerning a divergence between pressurizer level and 12 pressure?

By that ques tion, I mean you have no basis g

(

13 for testifying, do you, that ainy of those four 14 individuals communicated that fact to B&W7 15 MR. MacDONALD:

Are you asking whether he 16 knew if any of those four individuals communicated 17 any f acts relating to saturation and its effect 18 on level to B&W7 19 MR. FISKE:

Yes.

20 Q

I take it, Mr. Zedsman, you do not have 21 any basis for testifying that either of those four 22 individuals communicated to B&W that they knew in a 23 transient where pressure decreases you can have pressurizer level increasing when saturation is reached?

<^T 24 b

25 MR. MacDONALD:

I am going to object to the 1

No proper foundation.

You can answer.

4 A

I am not aware of the communication in 5

those areas that they transferred, if any, to B&W.

6 Q

You have no knowledge that they did transfer 7

such information; is that correct?

8 A

I personally have no knowledge, yes.

I have no personal knowledge of that.

Is it correct that you have no basis for 15 telling us that the information concerning a divergence 16 between pressure and pressurizer level in March 1978

~

17 open PORV transient was communicated to B&W7 18 A

By that group, you mean?

19 Q

By anybody at Met Ed.

20 A

I have no recollection at this time of that

~

l 21 being transmitted.

22 Q

we were discussing at the end of the day l

l 23 yesterday questions relating to high pressure injection.

l l

24 A

Yes, sir.

25 g

You did understa'nd, did you not, before l

I 1

Zechman 568 2

the Three Mile Island accident, that the actuation of hi h pressure injection was itself a symptom of a loss 3

9 4

of coolant accident?

O 5

A I understood was one symptom provided that 6

the pressure got down to 1600 before it was activated.

7 Q

I think we have established yesterday that 8

HPI would come on automatically when pressure dropped 9

to around 1600.

10 A

What I am implying is that the leak may be 11 small enough that pressure may not drop -- if it is a 12 small break it may not drop to activate high pressure.

13 Q

You may have a loss of coolant accident in 14 which it was not low enough to actuate H PI in the first 15 place?

16 A'

Yes.

f 17 Q

If in the course of a transient pressure 18 dropped below 1600 and HPI at that point did come on l

1 19 automatically, that that fact itself, that is the very 20 fact that HPI had come on would be a symptom of a loss 21 of coolant accident?

22 A

could be a symptom of a loss of coolant 23 accident.

(~h 24 Q

Did you understand before the Three Mile V

25 Island accident that there was any other event or

1 ZOchnon 569

<- s()

2 type of transient that could actuate HPI based upon a 3

drop in pressure other than the loss of coolant accident?

4 A

Yes.

I understand that there were other 5

circumstances that could have activated the high pressure 6

system.

7 Q

Which in those circumstances --

8 A

Was not considered a LOCA.

9 Q

-- would cause a drop in pressure, right.

10 A

Yes.

11 Q

You were familiar, I assume, with the phrase 12

" overcooling"?

()

13 A

Yes, sir.

14 Q

Is an overcooling transient one which could 15 cause a drop in pressure and the actuation of HPI?

16 A'

Drop of pressure and level.

17 Q

And actuation of HPI?

18 A

Yes.

19 Q

You understood before the Three Mile Island 1

accident that if you had an overcooling transien t --

Assuming,by the way, we have reached that g

22 activation point.

Yes.

Zechman 570 2

Q If you had an overcooling transient, you 3

would expect to see a drop in pressure and a drop in 4

pressurizer levels is that correct?

5 A

Yes.

6 Q

You were not aware of any opposite trending 7

phenomenon associated with an overcooling transient:

8 is that correct?

9 I was trying to shortcut by using a phrase 10 used in other depositions.

11 MR. MacDONALD:

Just add the parameters you 12 are talking about.

13 Q

You were not aware prior to the Three Mile

14 Island accident of any circumstances under which an 15 overcooling transient as opposed to a loss of coolant let me -- pressure would decrease while 16 accident i

l 17 pressurizer level was ' increasing?

18 A

During an overcooling situation?

19 Q

Yes.

20 A

Not to my recollection at this point.

21 Q

I think you told us before that H comes 22 on automatically as part of the safety system whenever 23 pressure reaches or goes below approximately the 1800 24 pound set points is that correct?

2 Q

In a loss of coolant accident, what is it 3

that causes pressure to go down?

The fact that we are losing inventory.

If 5

we have a breach of the RC system and therefore losing 6

pressure.

7 Q

What is it in an overcooling transient that 8

causes pressure to go down?

pressure to go down?

9 A

The fact that 10 Q

Yes.

11 A

The fact that temperature is going down, you 12 are dragging heat away and temperature is dropping and

13 pressure is dropping.

14 Q

was it important to you in running the 15 Training Department at Met Ed that you be advised in 16 the Training Department of situations during the 17 operation of either unit in which a transient had 18 occurred which activated HPI?

In other words, to put 19 it simply, was it important to you in the Training 20 Department that you learn about any transient that 21 occurred at either plant where HPI had come on?

22 A

During operations of the plant?

23 Q

Yes.

A Not testing or anything of this sort?

not significant that would not be important to the 7

I was trying to explain.

12 A

I wasn't finished yet.

I was trying to get

13 my thoughts together.

14 Q

Maybe I can make it clearer.

Based on your 15 understanding before the accident, would there be a 16 transient during normal operations in which there was such a decrease in pressure that HPI came on requiring 17 of emergency procedures to restore the plant to 18 the use normal condition that you would consider insigificant?

19 MR. MacDONALD:

Are you asking if anything 20 that occurred he considered insignificant?

You 21 have to deal with his recollection.

22 MR. FISKE:

I will ask if he remembers any 23 such actuation of HPI which.he then analyzed and 24

decided was insignifcant.

I will ask him that.

Q Let me ask the next question.

Making it 8

clear, I am asking for your understanding before the 9

Three Mile Island accident.

10 Did you have an understanding then that 11 there could be transients during operations in which 12 there was a drop in pressure large enough to actuate 1

13 automatically a safety system requiring the application l ()

l 14 of emergency procedures to bring the plant back to a 1

15 normal condition which could be termed insignificant?

2 before the accident how that worked or why that 3

happened.

4 A

A drop in temperature?

5 Q

Yes.

We are talking about a cooldown 6

transient.

We are backing up a little bit.

Before 7

the break we were talking about two different types of 8

situations which could cause a drop in pressure 9

sufficient to actuate high pressure injection 10 automatically.

One was a loss of coolant accident 11 and one was an overcooling transient.

I think you 12 described how it was that a loss of coolant accident O(_)

13 could cause a drop in pressure simply because there was 14 a loss of coolant through a break in the system, and I 15 think that is clear.

You also said that in the case 16 of an overcooling transient, what would cause the drop 17 in pressure was a drop in temperature.

18 I think it would be useful in this deposition 19 how in an overcooling transient that a drop in temperature 20 produced a drop in pressure.

l A

A decrease in temperature, the RCS liquid 21 22 results in the shrinkage of the system resulting in a 23 decreasing level and pressure.

7T 24 Q

Is there during normal operations a O

relationship between the temperature in the primary 25

I 1

Zechman 576 O

2 system and the temperature in the secondary system?

3 A

Is there a relationship, did you say?

4 Q

Yes.

G 5

A You are dragging from a hot to a colder 6

system.

7 Q

It is correct, is it not, that in the so-8 called primary system there is a hot leg and a cold 9

leg?

10 A

Yes.

11 Q

And the hot leg describes that part of the 12 system through which the water flows after it has gone 13 through the core on its way to the steam generator; 14 is that correct?

15 A

That's correct.

16 Q

As the water passes through the steam 17 generator in the primary system pipes, it transfers 18 heat from those pipes to the water in the steam 19 generators is that correct?

20 A

correct.

Which then heats the water in the steam 22 generator up to a certain temperature?

Somewhere around 605 degrees.

4 Q

After it passes through the steam generator 5

and becomes part of the so-called cold leg, it has 6

dropped in temperature to approximately 550 degrees?

7 A

somewhere in there.

0 K-21 Q

It then passes through the steam generator 22 and transfers some of its heat to the water in the 23 steam generator and the result when it comes out of the steam generator and enters the cold leg it is down 24 25 to about 550 degrees.

this moment, is it correct then that prior to the Three aware of any event 10 Mile Island accident you were not 11 which could cause a drop in pressure to actuate high 12 pressure injection other than a loss of coolant accident, l

an open PORV or an overcooling?

There may be others, I just can't think of 15 any other at this moment.

Putting it another way to make it more 8

simple, Mr. ~ Ze chman, did you explain to the operators 9

in the training program that if high pressure injection 10 came on in the course of a transient accompanied by an 11 increase in temperature, that that would be an indication 12 that they were not in the middle of an overcooling O'

13 transient?

6 No.

The answer is no, I never considered that.

7 Q

Having just told us that what produced an 8

saying that you never considered that an increase in 10 temperature would produce an overcooling transient?

25 the other parameters are and make that evaluation.

1 1

Zechman 585 ON]

2 Certainly one of the things they are looking for in 3

overcooling is a decrease in temperature and pressure 4

together.

That is one of the symptoms but that is not O

5 the only thing we are looking for in making those between those situations you have hypothesized that we 6

7 looked for.

8 Q

I am not saying this is the only thing they 9

should look to.

Indeed, we went through a procedure 10 yesterday which listed a number of separate specific 11 things that should be looked to which might be uniquely a steamline 12 characteristic of a LOCA as opposed to

'\\

13 break and as opposed to a tube rupture.

We have already 14 covered all that.

I am simply focusing on the moment for this additional consideration.

I think you have 15 16 told us that it was your understanding before the 17 accident that you could not have an overcooling transient 18 where there was an increase in temperature as opposed 19 to a decrease, and I am asking wasn't that part of the 20 training program?

I am not saying the only thing.

I am saying was that part of the training given to the lll 21 22 operators that trying to determine in the course of a transient whether or not there was an overcooling 23 involved, that one of the things they should look at

ZECHMAN, resumed:

6 BY MR. FISKE:

7 Q

Mr. Zechman, before lunch we were talking 8

about the training that was given to the operators at 9

Met Ed on how to differentiate between a LOCA and an 10 overcooling transient when they saw a decrease in 11 pressure which was sufficient to actuate high pressure 12 injection.

O What I would like to ask you now is what 13 the Three Mile was your understanding at the time of 14 to what would happen if in the course 15 Island accident as 16 of an overcooling transient the operators left HPI on 17 longer than they should have.

18 A

Assuming now that the HPI is on and that 19 there is an overcooling and temperatures are continuing to decrease because of that overcooling?

20 Q

Correct.

lh 21 A

Levels are increasing.

Pressure and 22 23 temperature are decreasing and levels decreasing.

One was to of the concerns the operators were told about

()

24 maintain level in the pressurizer.

Don't let it go out 25

1, 588 1

Zechman O

2 the bottom.

Don't let the level go out the top of 3

the pressurizer.

They were trained to operate high injection in such a way to control the 4

pressure O

5 overcooling event.

I 6

Q Let's put it in a slightly different way 7

in light of the answer you just gave.

You said it was your understanding and your Training Department's 8

9 position, right up to the time of the accident, that 10 pressurizer level was an accurate measure of inventory 11 of the system, correct?

12 A

That's correct.

O-What was your understanding of a situation 13 Q

14 in which the system was full and the pressurizer level 15 was full, what would happen if under those conditions the operators continued to leave HPI on?

16 17 A

I don't recall.

18 Q

I think you testified yesterday that~you did understand that if the operators terminated HPI 19 had during a loss of coolant :ccident when the pressure 20 there was not come back up to the actuation point that lh 21 a risk that the pressure could continue to_ decrease to 22 23 the point where saturation would occur.

I think we end of the day.

spent about a half hour on that at the

(

24 What MR. MacDONALD:

'I am going to object.

25

I 1

Zachman 589 bv 2

he said was said.

If you want to go back over the 3

ground, fine.

I don't think necessarily your 4

characterization is right.

That's all, Mr. Fiske.

O 5

Q Let me read you the last two questions and 6

answers from yesterday's deposition.

I 7

" Question:

My question is did it occur 8

to you before the accident that if the operators had is been given training and instruction on when it 9

proper to termknate HPI either didn't understand those 10 11 instructions or failed to follow them or made a mistake 12 or for whatever reason terminated HPI when, in fact, the O

13 HPI should have stayed on,that,one consequence of their 14 doing that, that is improperly terminating HPI would 15 be to allow a continuing drop in pressure?

"Mr. MacDonald:

Did that ever occur to you?

16

" Answer:

Yes.

17 18

" Question:

And that a continuing drop in 19 pressure if it went far enough to cause boiling?

" Answer:

And this is where I think we have 20 our differences.

As a theoretical point, I understand lll 21 that that will occur."

22 That is from the end of yesterday's session.

23 24 I would like to proceed from those answers.

Did you

()

25 understand that if a transient had been diagnosed as a

1 590 i

zechman 0

2 loss of coolant accident and that a loss of coolant 3

accident was in progress, that the operators should 4

not terminate HPI until at least pressure had returned O

5 to the actuation point?

6 A

The focus on HPI has always been to maintain 7

level and their focus was on level.

Everything we 8

observed in the past maintaining HPI for a LOCA, pressure 9

and level stay together.

10 Q

And as you said, that was also true for an 11 overcooling; is that correct?

12 A

Would you like to state that question again?

13 I said what for overcooling?

591 I

Zechman (O) 2 A

I repeat what I said.

When I said "we,"

\\_J 3

I referred to our operators at the simulator and our 4

own in-house training.

O 5

Q The "we" is confined to your operators?

To the training of the operators.

6 A

7 Q

It is not intended to speak more broadly else in the Met Ed organization, 8

and include anyone 9

other than just the operators; is that correct?

attended 10 A

well, it depends whether the others 11 the operator training program.

12 Q

were you intending to include Mr. Floyd, Mr.

O'Hanlon in the use of "we" 13 Toole, Mr. Miller and Mr.

14 in that sentence?

What I was referring to in that

~

16 was referring to was that in the training, whether it 17 was Mr. Floyd or Mr. O'Hanlon who went through the referring to them who went through the 18 training, I am 19 training at the simulator and in-house.

That's what I was referring to.

20 21 Q

I would like to go back to the question that lll 22 I started with and I think it is probably easier to put 23 it again.

Did you understand that if it was diagnosed

come on, that the HPI should not be terminated until 4

at least the pressure had been restored back to the O

it had been automatically activated 5

set point at which 6

for safety reasons?

so you understand, I am not asking i

7 you to get into the question of how that diagnosis would i

f 8

take place.

I am asking you whether after the diagnosis 9

had been made, on whatever basis, it was determined that 10 you, in fact, had a loss of coolant accident in progress 11 resulting in a drop of pressure sufficient to 12 automatically activate HPI, did you understand that it 13 would be wrong to terminate the HPI until the pressure 14 had been restored at least back to the actuation point?

15 A

In the operation of the HPI it was always 16 focused on maintaining level in the pressurizer and 17 pressure would follow that.

It was the level that 18 was the major concern in past training.

19 Q

Are you saying that if there was a loss --

20 knew a - loss of coolant accident was going on and 21 as you were looking at the instrumentation you were lll that told you that 22 seeing on whatever basis symptoms 23 there was a LOCA in progress, that you would turn off 24 the HPI, if the pressurizer level was high?

the fact that there could be circumstances when not an accurate indication of 9

I am not particularly anxious to 11 go through that all over again.

I would like to finish 12 this deposition.

I am simply asking you once again i

13 that if it were diagnozed that there was a loss of i

coolant accident in progress because of a lot of other i

14 symptoms besides pressurizer level or including 15 16 pressurizer level, that there was a diagnosis that you had a loss of coolant accident in progress, didn't 17 l

Q Didn't your own training at Met Ed,even 3

without knowledge,as you have testified of the fact that 4

there could be a difference between level and pressure O

5 when saturation was occurring in the system, even 6

without that knowledge for the moment, wasn't your 7

training to the operators that they should look at 8

level and pressure before determining to terminate HPI?

9 A

I think I answered that question by saying 10 that the training we had focused on level and in the 11 past the pressure always.

12 Q

In other words, it didn't make any 13 difference what the pressure was, you just looked at 14 the pressurizer level?

15 A

It never occurred -- in the pastit was never 16 separated.

They were together.

17 Q

Isn't it a fact, Mr.Zechman, that your 18 training taught them that they should look at level and 19 pressure, both, before terminating HPI?

A The training we received from the simulator 20 and in-house focused on maintaining level to insure lll 21 22 adequate RCS coolant.

By virtue of that in the past and everything we observed, pressure stayed with it.

23

/~N 24 Q

In other words, you were told that both 25 pressure and level were important, were you not?

HPI after it had come on in the phase of a drop -

Maintaining level that pressure would also 9

be controlled, we told them.

10 Q

So that pressure was important?

In other 11 words, what you are saying, is it not, that you told level as an 12 the operators that they could look at

13 indication of what the pressure was?

14 A

We trained them that by maintaining level t

l inventory would be maintained and 15 sufficient core l

16 pressure would follow it because that is the way we were 17 taught at the simulator and in-house.

18 Q

If pressure followed it,then they could terminate HPI when they got back up above the actuation 19 l

You may be right. I don't recall the exact 15 facts on numbers that we had.

I know there were times 16 there was a significant number of hours.

17 Q

And the training on the B&W simulator 18 during the period of time that you were head of the 19 Training Department was one week every two years, is 20 that correct, about 40 hours4.62963e-4 days <br />0.0111 hours <br />6.613757e-5 weeks <br />1.522e-5 months <br />?

In any event, would you debate any further the quantitative differences between the training at ll) 21 22 Met Ed and that at B&W7 sounds to me that an extraordinarily It 23 at high reliance was put by the Training Department 24 Met Ed on the situation of level in the pressurizer.

25

598 Zechman 1

2 MR. MacDONALD:

Object to the form.

What 3

do you mean by " extraordinarily high reliance?

4 Q

Do you think that is an unfair characteri-0 5

zation, Mr. Zechman?

6 A

If you are referring to the number of hours 7

spent on that issue, yes, I think that's unfair.

8 Q

I an not talking now about the number of 9

hours that that subject was covered.

I am talking 10 quantitatively, or rather substantively, qualitatively 11 about the situation that was given in your training an accurate 12 program to pressurizer level as being 13 reflection of inventory in the system and just from 14 the numbers of times that you referred to it in the 15 response to questions that I asked, whether they are 16 related to that or something else, I will draw the 17 conclusion, which I invite you to correct if you think 18 it is wrong, that the Met Ed Training D'epartment'put 19 heavy reliance on that in the training of its operators.

A You have got to put it in the framework 20 in which our discussions took place.

We were talking jll 21

-- where we 22 about transient conditions and we went learned to operate under transient conditions was at 23 24 the simulator.

That was the main focus of the simulator 25 to look at transients and do different things on the

I 1

zechman 599 A

2' simulator.

That's where we learned that concept.

3 Q

You didn't confine your information about 4

how to deal with transients to the B&W simulator program, O

5 did you?

Putting it another way, wasn't it important 6

for you to get what information you could about 7

transients from whatever source?

8 A

I am not saying the only source of 9

transient information came from B&W.

10 Q

Accepting that and taking whatever you know 11 about transients or didn't know about transients in the 12 Met Ed Training Department, from whatever source, isn't F 's

\\_/

13 it a fair characterization of your training program i

i that you placed heavy reliance on the pressurizer level 14 15 as being an accurate indicator of system inventory 16 during the training that you gave your operators?

17 A

I guess I take issue with " heavy emphasis."

18 It was characteristic of what we learned in operating 19 RCS system and how we performed at the simulator and what we have learned in the operation of that system 20 over the years.

Mr. O'Hanlon, Mr. Miller, Mr. Floyd and Mr. Toole?

3 A

I certainly did imply to include anyone 4

who went through our program and got licensed.

Went llh through the same training, went to the same kind of I

MR. FISKE:

Could you read the last answer 8

Was Mr. Floyd licensad?

11 A

He was.

Presumably Mr. Floyd was taught during your

an accurate training program that pressurizer level was 14 msasure of inventory in the system?

15 A.

To the best of my recollection, he went 16 through that same training, both at Met Ed and at the 17 simulator and had that reliance.

18 Q

He knew then, did he not, that your training 4

19 program at Met Ed was teaching the operators that they 20 could rely on pressurizer level as being an accurate II, 21 reflection of system inventory?

with respect to dealing with an open PORV, we went through earlier in the deposition procedures that were 10 11 designed to diagnose an open PORV and prescribe the 12 treatment for an open PORV once it has been diagnosed.

6 Q

Did they have to have a license from the NRC to conduct a simulator training program?

7 8

MR. MacDONALD:

I am not quite understanding.

A license in what sense,the same sense as operating 9

i 10 a nuclear plant?

In other MR. FISKE:

Any kind of a license.

11 12 words, did B&W have to have approval in the form of any kind of a license from the Nuclear 13 l

Regulatory Commission in order to conduct a 14 training program in Lynchburg?

15 They have an approved program for the 16 A

r 17 start-up

a. certification program.

18 Q

Was that part of the training you sent your 19 operators to?

A Yes, it was.

3 Q

Any kind of a license?

4 MR. MacDONALD:

I object.

I don't know what O

5 you mean.

6 MR. FISKE:

I couldn't make it any more 7

simple.

8 Q

You understood, Mr. Zechman, that when Met 9

Ed operated Unit 2 they were doing that under a license from the Nuclear Regulatory. Commission and that they 10 11 couldn't operate the plant without that licenser is 12 that correct?

v 13 A

I understand that.

14 Q

Now I am asking you with respect to the 15 B&W simulator program that we have been discussing 16 here, did you understand that B&W was running that from the simulator program under any form of license 17 18 NRC and that they couldn't conduct it without approval 19 from the NRC?

A To the best of my recollection, they did not 20 have-- the simulator did not have an operating license 21 similar to an operating license at a commercial plant.

22 The simulator did have to have an approved start-up 23 certification program.

24 25 Q

Did you understand that if the NRC found

1 613 Zechman 1

O training was being given to operators 2

that inadequate 3

at Met Ed with respect to dealing with emergency 4

transient situations, that that would be a basis upon 6

which they could find the training program insufficient 5

6 and take away the license?

7 A

I recognize that they provided audits of insure we were in compliance 8

our training program to 9

with the program.

And that if there were problems in identified at that time the training program they were 10 and evaluation of the situation of those was made by 11 12 the INE.

O So you understood they were doing audits?

13 Q

f A

Yes, sir.

14 15 Q

Did you understand that if the NRC concluded 16 that the training given to Met Ed operators with respect i

in a transient were to handling emergency conditions 17 18 inadequate, that that could put Met Ed's operating 19 license in jeopardy?

A You are asking me this prior to the accident?

20 Q

Yes.

lll 21 A

Prior to the accident I guess I never 22 vein because our programs and our considered it in that 23 audits always had that program and never thought our

like that.

3 Q

You mean the thought never crossed your 4

mind at any time when you were head of the Training O

5 Department as to what might happen if the NRC concluded 6

that your training was inadequate?

7 A

No.

8 Q

That was my question.

9 A

Certainly I knew we had commitments for 10 our training programs.

I knew we were audited against 11 those.

12 Q

And you knew if the NRC concluded that 13 the training being given to your operators handling 14 emergency conditions in the course of a transient 15 were inadequate that that could put your license in 16 jeopardy?

17 A

I certainly understood that if our -- if 18 they determined our training was inadequate for whatever 19 reason, that some resolution would have to be made and some determination of what the penalty for that 20 l

l 21 would be.

Whether it is a follow-up, whether it is 22 a fine, whatever.

and did it 3

the Training Department that you better be sure in your 4

own mind that you are satisfied that the training that 9

the operators on dealing with emergency 5

is being given to 6

conditions in a transient is sufficient?

7 A

Please read that question back.

8 (Question read)

I As head of the Training Department, 9

A 10 relied on the procedures that were given us in the in the training and guidance 11 operation of our plant, 12 that we received and the training we received at the O

13 simulator.

What is adequate and sufficient is 14 everybody's responsibility, not just the head of the 15 Training Department.

That includes the training we 16 got from the simulator as well.

It is everybody's 17 responsibility to insure that we have procedures and that we receive training accordingly.

18 19 Q

If the training was adequate, including 20 the trairing at B&W, Met Ed was the one who was going to i948e the license; is that correct?

that you had at Met Ed, the training program met the 4

requirements of the code of federal regulations?

O 5

A As I said, it was a cooperative effort 6

on what was adequate.

Certainly we relied a great deal 7

on the vendor of the plant to be able to tell us how 8

to operate that plant.

9 Q

'I think you have said that on numerous 10 occasions, and I think we understand that.

11 A

O.K.

Therefore we relied on them giving 12 the correct information on the operation on that plant.

13 You can't separate that.

14 Q

What I am getting at, Mr. Zechman, you 15 didn't put a blindfold over your eyes insofar as 16 emergency training procedures are concerned.

"I wouldn't 17 worry about that, that's being done at B&W.

I don't 18 have to look what they are doing or whether I think l

19 that's sufficient.

I will let them do that and I won't 20 pay any attention to it"?

21 A

I didn't imply that at all.

If that is to imply that I thought of every 0

the operation of that plant, I don't believe I am a 7

superman of that type.

8 Q

Do you think there are supermen of that 9

type at B&W?

think the people who manufactured the unit 10 A

I 11 certainly should be expert on that unit.

12 Q

And shouldn't the people that are operating O

13 it.also be expert on the operation of that unit?

They should be expert on the operation based 14 A

the question of if pressure decreases, did I have an O

decreased that the boiling could have occurred.

I 7

already stated from a theoretical standpoint I understood 8

that.

You referred several times during this 9

Q 10 deposition to the fact that you knew that from a 11 theoretical standpoint.

I take it that once, in fact, 12 the pressure reaches that point and boiling starts, it s/

13 is not theoretical anymore?

12 that decreasing pressuring as applied to our plant O

going to cause boiling because our emphasis wasn't 13 was i

on that.

14 Did you think there was something different l

15 Q

from other prassurized water reactors 16 about your plant 17 so that a drop in pressure wouldn't cause boiling at 18 your plant?

A The focus was on maintaining level such 19 that inventory -- I am trying to tell you that our 20 training was such that our focus was not on that and lll 21 therefore not considered.

22 23 Q

In other words, that was the focus, you say, training that you gave your operators in the Met of the

24 Ed training program?

25

628 Zechman 1

O 2

A I am saying the focus of our training both 3

from B&W and in-house was on maintaining level and as 4

long as we did that, the core'was sufficiently O

5 inventoried.

6 Q

I guess you are telling us that for whatever 7

reason, nobody ever brought to your attention or 8

anybody else's in the Training Department the fact 9

that incidents had occurred at TMI-2 in which there 10 had been saturation as a result of drop in pressure?

11 A

I think I already testified to that, sir.

So nobody told you that this theoretical 13 concept that you described had, in fact, occurred in 14 real life on more than one occasion, right there at 15 Unit 27 16 MR. MacDONALD:

My prior knowledge and own training relative 2

to fuel damage had to do with transfer of heat from 4

the elements relative to DNBR.

It did not have anything 9

5 to do, it did not -- well, that's what my prior 6

experience has been.

7 Q

You did understand, did you not, that 8

boiling in the reactor coolant system could cause 9

damage to the fuel?

10 A

Again, I put it in the light that we are 11 talking about damage to the fuel-in relationship to the 12 fuel-being able to transfer heat to the coolant.

Not 13 as the RCS, as a collectivs body.

For whatever the mechanics.of it were,you

publication that was part of your materials in your 3

training program.

Do you understand that?

4 A

I can't speak for Mr. Geissler.

I can only 0

5 speak for myself.

6 Q

I just want to make it clear what I am asking 7

you.

I am asking it in reference to the sentence in Mr. Geissler's part of this publication which reads, 8

"If pressure decreases, the possibility exists that 9

10 boiling will begin."

That is the type of boiling I 11 am asking you, the type of boiling that results from a 12 decrease in pressure and goes on to say, "which may 13 produce a sufficient change in the heat transfer from the core to cause damage to the fuel."

14 I am simply asking you, didn't you understand 15 16 before the accident that if boiling occurs as a result 17 of drop in pressure that that boiling by whatever means 18 can cause damage to the fuel?

I A

I am going to repeat my testimony that 19 already said, I theoretically understood that if pressure 20 I will repeat that dropped that boiling could occur.

ll 21 the core my limitation -- my understanding relative to 22 fuel or had to do with surface effects on the and DNBR 23 in channels of the fuel.

24 25 Q

Taking that answer as you gave it, am I e

n r..-

I 632 Zec hman 1

0 in understanding that you did know before the 2

correct 3

accident that if boiling occurred in the reactor coolant 4

system as a result of drop in pressure that boiling 5

could cause damage to the fuel?

It was referred to localized boiling in 6

A 7

the core.

Never in reference to bulk boiling in the 8

RC system.

9 Q

What produced this localized boiling that 10 you are referring to?

11 A

You have -- assuming the worst case where 12 you are going to get localized effects on the field.

Broad configuration could localize the heat in a 13 Particular part ti the core.

Localizing it to a 14 i

15 Particular fue1 assembly.

I 16 Q

So in other words, if there was localized boiling as you have just described it that could cause 17 18 damage to the fuel at the point where that boiling occurred, is that your testimony?

19 A

Our training was such that we realized the 20 difference of nuclear boiling to film boiling. If the 7g heat transfer was through one of those modes that that is 22 the surface effect you would get.

23 And that boiling could be produced by a Q

24 drop in pressure?

A No, that's where we differ.

3 Q

You are talking about some type of boiling 4

that occurs without a change in the basic pressure 9

temperature relationship?

5 6

A Due to the localized flux distribution.

7 Q

That is one case, the localized flux 8

distribution.

Didn't you understand that if that same 9

type of boiling was caused by a drop in pressure that 10 the same would occur?

That never occurred to me prior to the 11 A

12

accident, You certainly had no reason prior to the 13 Q

14 accident to exclude that type of boiling as a cause for 15 a type of fuel damage?

16 A

I repeat that that never occurred to me 17 prior to the accident.

18 Q

Let's get a couple of basic things here 19 straight.

Didn't you understand before the accident that what keeps the water in the reactor coolant system 20 from boiling is maintaining the proper pressure lll 21 22 temperature relationship?

I A

I told you from a theoretical point 23 understand that a PWR operates at elevated pressures 24 s

25 to prevent boiling.

2 Q

And if the pressure drops below what you 3

referred to before as the Tsat temperature, then 4

you will have boiling; is that correct?

O 5

A Repeat that question.

6 (Question read) 7 A

From a theoretical standpoint, I understand 8

that when the pressure drops from that point you would 9

have boiling.

10 Q

Let's look at the steam generator for a 11 second.

All right?

12 A

o x, 13 Q

What types of fluid are in the steam

(

i 14 generator?

15 A

We have liquid, we have steam, and we have 16 superheated steam.

17 Q

What did you understand caused the change 18 in the steam generator from water into steam?

19 A

Transfer of heat from the primary to the l

the water passed through the tubes, passed 20 secondary as 21 by the tubes, the water would heat up as it traveled lll l

22 up to a point where it flashed to steam and then went by a section that was not wetted and picked up more 23, 24 heat and became superheatcu.

What turned the water in the steam generator i

relationship; is that correct?

4 A

I understand that.

That's the way the G

5 training was.

6 Q

Nothing theoretical about that?

7 A

That's correct.

8 Q

You certainly understood if that same type 9

of change occurred in the primary side you would have j-10 steam in the primary side?

never occurred to me prior to the 11 A

That 12 accident.

We didn' t discuss that.

You mean it never occurred to you once 13 Q

14 before the accident as head of the Training Department 15 at Met Ed that if in the primary system the pressure relationship changed entirely that you --

16 temperature Is that 17 the water in that system could turn to steam.

It never occurred to me prior to the accident k

s of having a saturated RC system.

20 21 Q

Any saturation in the system outside the ggg 22 pressurizer?

From a theoretical standpoint I A

Yes.

23 understand that.

From a practical application to our 24 25 reactor, I did not consider that.

to the fuel Did you understand that damage 8

Q the possibility of radiation being 9

could increase 10 released into the atmosphere?

11 A

I certainly understood if the fuel damage 12 was significant enough, the f is sion products were released to the RC system, that there are sets of O

13 radioactivity under certain conditions in which that 14 conditions could be released to the atmosphere.

You 15 16 have to have a whole set of conditions, different 17 Paths that would have to take for that to happen.

18 Q

Is it correct that if the damage to the --

that you understood prior to the 19 isn't it correct accident that if the damage to the fuel resulted in 20 into the reactor the release of radioactive material lll 21 at that that there was only one barrier left

related to the transfer of heat from those elements.

4 It was not related to a. decrease in pressure of the 5

RC system.

6 Q

So that it never occurred to you that 7

boiling which resulted from a drop in pressure could 8

cause fuel damage which could increase the dangers 9

of releasing radiation; is that your last answer of the 10 day?

11 A

Repeat the question.

I already testified to that in my previous 14 answer.

15 Q

Do I understand that the answer is no?

The answer is prior to the accident it did 17 not occur to me of that relationship.
