3 MR. SHACKLETON: The date is December 31, 1981.
4 The time is 1:24 p.m. This is an interview of Mr. Edward 5 T. Denison, who is employed as an engineer in the Robert 6 L. Cloud Associates, Inc., in Berkeley, California. This 7 interview is taking place in the offices of the Robert 8
L. Cloud Associates, Inc., at 125 University Avenue, g Berkeley, California.
to The purpose of this interview is part of the 33 investigation being conducted by the US Nuclear Regulatory 12 Commission to develop the facts and happenings surrounding 33 the present reverification program of the seismic design
(, In addition to 14 of the Diablo Canyon nuclear power plant.
15 Mr. Denison, present to conduct this interview from the 16 US Nuclear Regulatory Commission, Region V, is Mr. Philip 37 J. Morrill, a reactor inspector. My name is Owen C.
Shackleton, Jr., and I am a senior investigator.
l 18 39 Mr. Denison, prior to going on record, I advised i
.j 20 you of your right to have personal legal counsel present. ,
l 21 Do you waive that right?
I MR. DENISON: I waive that right.
f 22 MR. SHACKLETON: Thank you. And I would ask you 23 24 on behalf of the Commission to please keep the testimony 25 that you are giving to the commission at this time confi-
-521-
(' I dential . Is that understood?
2 MR. DENISON: It is understood.
3 MR. SHACKLETON: Thank you. Would you please 4 rise for the oath.
5 Whereupon, 6 EDWARD T. DENISON 7 was called?as a Witness and, after being duly sworn, was 8 examined and testified as follows:
9 MR. SHACKLETON: Mr. Denison, would you please 10 state your full name?
11 MR. DENISON: Ldward Tyler Denison.
12 MR. SHACKLETON: And would you please give your
, 13 Professional title?
14 MR. DENISON: Engineer.
15 MR. SHACKLETON: And how long have you been 16 employed by Robert.L. Cloud & Associates, Inc.?
17 MR. DENISON: Since May of '81.
l 18 MR. SHACKLETON: Are you now presently assigned g 19 to working on the reverification program for the Pacific c
j 20 Gas & Electric Company?
f 21 MR. DENISON: Yes.
I f 22 MR. SHACKLETON: When were you assigned to that 23 contract?
24 MR. DENISON: October ll.
25 MR. SHACKLETON: Were you involved in the revi-i k.
-522-i
() i sion work that was carried on on the October 21, October 26, 2 and November 6 draft reports?
3 MR. DENISON: Yes, I was.
4 MR. SHACKLETON: Could you please tell us what 5 were the original instructions provided to cloud enployees 6 performing the development of the report and handling of 7 comments? When I say report I had better make that plural 8 because we are addressing the drafts that I identified g before.
30 MR. DENISON: Now we're talking about the period ji after the 21st.
12 MR. SHACKLETON: Yes. That's correct.
13 MR. DENISON: Our instructions were to address t
14 the comments . " Address the comments" entailed several 15 things. If the comment was unreasonable then it was left 16 as is. If it was reasonable and it was correct, the
- 17 changes were made in the report. If the conment alluded
=
to additional information, we sought to get that additional l 18 l g ig information.
l :
I j 20 MR, SHACKLETON: How were these comments given
, ! 21 to you, Mr. Denison, for the revisions requested by PG&E l i f 22 employees?
23 MR. DENISON: We were given marked up copies.
24 MR. SHACKLETON: Now when you say marked up 25 copies, these were copies of the rough drafts, is that
(
-523-l
(hl 1 correct?
2 MR. DENISON: That is correct.
3 MR. SHACKLETON: Were there any additional 4 documents suggesting or requesting revisions other than 5 those markings that were c., those draft reports?
6 MR. DENISON: Yes.
7 MR. SHACKLETON: How were these maintained, 8 these other documents?
9 MR. DENISON: When you say maintained --
H) MR. SHACKLETON: Have they been kept on file so ij that they are available for reference?
12 MR. DENISON: They were not kept on file at 13 the time. They were kept and they are now presently on C'
file.
14 15 MR. SHACKLETON: Am I understanding you correctly 16 that some of those documents now are gone? Were they
. 17 thrown away or destroyed?
l I
l H3 MR. DENISON: No, that's not what I said. What
- ig I said was at the time we received the documents they a
j 20 weren't filed in our systen at that time, f 21 MR. SHACKLETON: But they are now all available?
a f 22 MR. DENISON: They are now all available.

! 23 MR. SHACKLETON: Did you receive any verbal 24 comments from Pacific Gas & Electric, Westinghouse, or 25 any other company personnel concerning recommended revisions b
-524-l
- _ _ _ _ _ - - - _ _ - - - - _ _ - - _ _ _ _ - _ _ -. __ J
h i to the October 21, October 26, and-November 6 draft reports?
2 MR. DENISON: I had nothing to do with any 3 people from Westinghouse. I had a lot of interface with 4 Dave Lang of URS/Blume. I didn't receive any comments 5 on the drafts from Dave Lang. I don't believe he even 6 read the drafts. As for PG&E people, I did receive oral 7 comments from them.
8 MR. SHACKLETON: Could you tell us for the record g how were the oral comments recorded, if they were recorded?
10 MR. DENISON: Well, the oral comments originally 11 would have started out as a written comment. If I got a 12 draft report in front of me on one of the sections I was j3 responsible for it would say something to the effect "this
(- i4 is incorrect" and for the next revision I would either call 15 up the engineer, the responsible engineer at Pacific Gas 16 & Electric, or I would talk to him in person. I can docu-
- 17 ment some of those meetings.
l l '
18 MR. SHACKLETON: So in response to ny question, I
g 19 Mr. Denison, were all these verbal comments documented?
a j 20 MR. DENISON: They were not all documented. I only documented a connent when it resulted in action. If it f3 21 i
l J 22 led me to change.my section of the report then I documented 23 it. If we discussed an issue and there wasn't a change 24 made to the text,' generally.I didn't document it.
25 MR. SHACKLETON: Did you follow the original l
(
l
-525-
?
( 1 guidance provided regarding preparation of the interim 2 report and handling of comments? The interim report now, 3 what I am referring to is 'Mrs report that Cloud made avail-4 able I believe around November the 12th. What I am addres- ,
l 5 sing, Mr. Denison, is what is commonly referred to I believe e in this situation as the interim report.
7 MR. DENISON: We call it the preliminary report.
8 MR. SHACKLETON: Okay. Use your terminology.
9 MR. DENISON: Okay. We have a final preliminary 10 report, if you will, on November 12. Now you are talking 33 about the period after that?
12 MR. SHACKLETON: No. The question is, did you
. 13 follow the original guidance provided -- and I assume you 14 had guidance during the course of the preparation of this 15 preliminary report -- regarding preparation of the report 16 and handling of comments?
- 17 MR. DENISON: We followed the same procedure throughout, l 18 19 MR. SHACKLETON: Throughout?
i 3
j 20 MR. DENISON: 23roughout the October 21 to 21 November 12 period.
i 22 MR. SHACKLETON: Thank you.
Do you have a question? Go ahead.
! 23 24 MR. MORRILL: Excuse me, Mr. Denison. What 25 sections were you responsible for? Do you recall?
k.
-526-
( 1 MR. DENISON: Well, the question is not exactly 2 answerable, but I can explain --
3 MR. MORRILL: In general terms.
4 MR. DENISON: -- what I'm telling you. I was 5 responsible, along with a Dr. Tom Slot from our East Coast 6 office, for the interface between Blume and PG&E. I was 7 personally responsible for the raceway supports and the 8 HVAC ductwork supports. Now in addition to that, the 9 interface from Blume to PG&E was documented in much greater 10 detail than the interface from PG&E to Blume. So if I was ij at Blume and they had, for example, telecons, copies of 12 telecons that PG&E had made for the other interfaces, and 13 I collected that kind of information.
(- g I also worked with one of our gentlemen, Shafi 15 Motiwalla, on the HVAC components. Since he has left the 16 company, I am sure I can answer any of the questions you
- 17 have on that area. In addition, I did some work on cranes,
=
j 18 I did some work on the aux saltwater pump. What we would y ig do is instead of five people asking the same person ques-a j 20 tions we would sometimes get together and decide all the
( l 21 information we needed fron a certain individual.and, rfor l
i f 22 example, I would go and talk to that individual.
MR. MORRILL: You mentioned Dr. Slot?
f 23 24 MR. DENISOM: Dr. Tom Slot.
25 MR. MORRILL : Okay. He is in your East Coast
(
-527-
- ?
hh 1 office?
2 MR. DENISON: Right.
3 MR. MORRILL : What was his involvement?
4 MR. DENISON: He was suffering from a severe case 5 of the flusat the time. His involvement was for two or 6 three days working on that Blune/PG&E interface. He would 7 not have had any direct input into any of the reports.
8 MR. SHACKLETON: Mr. Denison, were you encouraged 9 or directed by anyone to change any of the original findings 10 that you made from your own personal study?
11 MR. DEN.TSON : Well, each of the comments from j 12 the PG&E people in the sections that I was responsible for 13 was an encouragement of a sort. When someone crosses out
(. 14 three-quarters of a page and writes " incorrect", that is 15 an encouragement.
16 MR. SHACKLETON: Could you please for the record
- 17 tell us who'made these encouragements? You have identified l 18 that there was obviously someone from Pacific Gas & Electric.
g 19 Did you have any --
, j 20 MR. DENISOM: I'm not sure I can pinpoint comments 21 to certain individuals. I can give you the names of the 3
f 22 individuals in general that were responsible in my areas.
l 23 MR. SH ACKLETON: That would be helpful.
24 MR. DENISON: Igor Sokoloff, Otto Steinhardt, 25 and George Lenfestey were involved with the raceway supports,
(.
-528-
10 h!) 1 as was Felix Mao. Felix Mao and Graham Brotherson wers 2 involved in both the HVAC duct support and the HVAC compon-3 ents. Stan Hanusiak was involved with the containment 4 cranes, Panos Antiochos with the auxilliary salt water 5 pumps, Ming Lee with the intake structure, Chung Li with 6 the turbine building. I'm sure others will come to me, 7 but --
8 MR. SHACKLETON: Thank you. That is very good 9 recall. We 'll have to have your help of f the record for to the spellings.
ij MR. DENISON: Fine.
12 MR. SHACKLETON: Now regarding -- you've 13 enumerated many important parts of the Diablo plant which k.- you addressed. Can you give us to the best of your recol-14 15 lection what findinos were involved and what changes were 16 requested at that time?
- 17 MR. DENISON: All right. What I did was assemble
=
l 18 some cover sheets on the various areas I was involved in.
g 19 I think the first one we should talk about is the HVAC c
j 20 components, which was in actually Shafi Motiwalla's responsibility.
f2 21 MR. SHACKLETON: Could you identify for those f 22 23 persons who are not familiar with nuclear terninology in 24 simple English what you are talking about?
l 25 MR. DENISON: An HVAC component would be an l
-529-
11 (t/ ,
1 exhaust fan , a damper, filter, the mechanical equipment 2 involved sith restricting the flow of air, if you will.
3 MR. SHACKLETON: Thank you.
4 MR. DENISON: All right. The initial report 5 section on the HVAC components included reference to one 6 mistake or one finding, if you will. What Shafi was doing 7 at the time was he was comparing lists that had been pro-8 vided by PG&E to EDS Nuclear with two or three other lists 9 that EDS Nuclear had been using. These lists were basically to seismic response accelerations.
ij MR. SHACKLETON: Could you identify what EDS 12 Nuclear stands for, please?
. 13 MR. DENISON: I'm afraid I can't. It's EDS 14 Nuclear. It's a well-known --
15 MR. SHACKLETON: But it is another engineering to firm involved in the nuclear field.
- 17 MR. DENISON: Yes. That initial error that he j 18 reported was a difference from one list to the next list, g 19 As he stated in his rough notes, the list did not necessarily j 20 - - - the mistake, I'm sorry -- did not necessarily appear on f: 21 the final result. This was commented upon by PG&E. I f 22 believe Mr. Vince Ghio had a corment on that section that j 23 said to omit or change that section. Shafi went back and 24 talked to Felix Mao about the situation and Felix Mao 25 pointed out that, although an error might have been made in
-530-
l' L.
? 1 the transmittal of information from one list to another 2 list, the final calculation, the final qualification calcu-3 lation prepared by EDS Nuclear for PG&E, did not include 4 that error. Shafi took that comment at value and we 5 decided, however, that if comparing the lists did not 6 address the question then we should take a sample of what 7 the actual calculations used for seismic acceleration 8 values.
9 He and I selected four equipment groups: the 10 forced draft shutter damper, which is in containment; 13 supply fans S-31 and S-32, which are in the auxilliary 12 building; supply f ans S-6 7, 68 and 69, which are in the 13 turbine building; and exhaust fans E-101, E-102, E-10 3,
( 14 and E-104, which are in the intake structure. You will 15 note we took one from each of the four major buildings.
16 We looked at the actual values used in the calculations 17 and compared them to the values we personally took off g
the Hosgri response spectra and, in the case of I believe l 18
- 19 the force draft shutter damper, although the value had i
j 20 been taken correctly, the vertical value, in the process l 21 of the calculations the additional lg for gravity had not i
f 22 been added in. And in one of the other three groups there 23 had simply been an error. They had used the wrong value.
24 So the initial October 21 report would have 25 shown one finding whereas the final copy of the preliminary k
-53 b-
(f) 1 report on November 12 would have shown a sample of four 2 taken with two findings. And in that instance PG&E, by 3 providing additional information and additional insight 4 into the process, came up with an additional finding. That 5 is pretty much the story on HVAC components.
6 I have some cover letters and some memos to 7 file that Shafi Motiwalla wrote up on this matter which you 8 are welcome to see, you are welcome to take.
9 MR. SH ACKLETON : You don't have first-hand 10 knowledge on that other part you are just discussing ji that Shafi --
12 MR. DENISON: The lists you are speaking of?
,. 13 The lists I do have first-hand knowledge of. The lists
(
14 are available in our files. They are quite thick, that's 15 why I did not photocopy them. What these represent are 10 basically coversheets. One of these coversheets most likely 17 represents that group of lists.
l 18 MR. SHACKLETON: Would it be possible to have g 19 those documents as exhibits for your interview?
j 20 MR. DENISON: It certainly would.
l fa 21 MR. SHACKLETON: Would you please pass those l
f 22 to the court reporter and we will call the first document s
l 23 you addressed regarding the heating, ventilation and those 24 parts of the hardware as Exhibit No.1.
25 MR. DENISON: Why don't you make that the HVAC k..
-532-l
24
() i componentsnor HVAC equipment.
2 MR. SH ACKLETON : Okay. That will be Exhibit 1.
3 (The document was marked as 4 Exhibit No. 1.)
5 MR. DENISON: I can give these to you now; I'll 6 have to write a cover sheet before you can take them.
7 MR. SHACKLETON: That's fine.
g And the other document will be Exhibit No. 2.
9 MR. DENISON: Okay. This Exhibit No. 2, basically 10 the cover sheets now are log appendix or are log reference n table that includes both the components and the duct work.
12 (The document was marked as 13 Exhibit No. 2.)
(. MR. DENISON: The second group that I had 14 15 responsibility over would be the HVAC ducting. In this 16 instance, I met with -- I have a few more nanes for you --
, g7 I met with Eliot Nichols, Don Hagstrom, and Graham Brotherson f rom the civil HVAC group. And --
l 18 g 39 MR. SHACKLETON: Excuse me. These are all j 20 personnel with --
~
fa 21 MR. DENISON: Within PG&E.
J 22 MR. SHACKLETON: Thank you.
. 23 MR. DENISON: And Felix Mao from the civil 24 seismic group, if you will, 'to get the rough background 25 on the HVAC ducting. HVAC ducting, electrical conduit and
-533-
l' t
y (3) i electrical cable trace are similar in that the supports 2 themselves are qualified rather than the actual duct or 3 conduit. So that is one of the reasons I had that area.
4 I received from them transmittals and I asked to see the 5 qualification calculations for all the ductwork supports.
6 Felix Mao showed me a notebook and I asked him if that .
7 included all of the HVAC ductwork support calculations 8 and he said it did.
9 I selected a sample out of there and, in one 10 instance, there was a detail in the turbine building that ij did not specify the area or the elevation in which it 12 could be used. So I assumed the worst possible case in 33 the building and therefore care up with an error. This i4 was reported in the October 21 report and I believe it 15 drew a comment at that point from either Felix Mao or Igor 16 Sokoloff or Otto Steinhardt.
4
- 17 I met with Felix Mao on the 28th. He insisted
=
l 18 that that detail would use ground spectra only. We talked y ig about it for several days and eventually he convinced me a
j 20 that that detail was a shop drawing, a special support
! 21 design only for that area. I concurred with his conclusion i
that the vslues in the calculation was correct. However, f 22 23 it led to an additional question that if the calculations 24 in that book were for shop drawings, where were the calcu-25 lations for the regular Class 1 ductwork in the turbine
-534-l
I t,
( ; building. We discussed that on the 2nd of November. My 2
meeting with Felix Mao is documented. My note was "at 3 present, no Hosgri calculations exist to qualify Class 1 4 HVAC duct supports at elevation 140 in the turbine building" ,
5 That led me to wonder if that notebook had not 6
been complete in other areas. On the same day I got from 7 Mr. Mao calculations for intake structure ductwork. One 8
set was dated 19 74, which would have been pre-Hosgri. The g second set was dated that day, November.2, 1981. I believe
,g that is reported in the November 12 report, our preliminary g report. He stated that they could not find qualifications f r that duct and therefore had drawn up new calculations.
12 In this instance also the initial report cited 33
(, one finding and the report on November 12 cited two findings ,
34 S in this instance also, when additional information became 15 16 c ar, it led to additional questions and additional ' findings.
. 37 I also documented a meeting with Graham Brotherson to investigate the possibility of Class 1 duct-l 18 g ig work in the containment building because there were no c
qualification calculations for that building. He provided j 20 l 21 me with documentation, being Hosgri pages, HVAC drawings i
from the containment, and I was convinced that there was f 22 23 indeed no Class 1 Hosgri required ductwork in the contain-24 ment.
25 MR. SHACKLETON: What would be a good identifica-k..
-535-
J' (h) i tion? Is that a third document?
2 MR. DENISON: That's a third document. ,
3 MR. SHACKLETON: That would be Exhibit No. 3.
4 How should we best characterize that one?
5 MR. DENISON: HVAC duct supports.
6 (The document was marked as 7 Exhibit No. 3.)
8 MR. DENISON: The third area would be electrical 9 raceways. I think for the electrical raceways it is much to more complicated than the other two. I think we should 11 run through the history of it, just the initial history.
12 MR. SHACKLETON: Please do.
13 MR. DENISON: Initially I took a sample of ten i
14 calculations that I selected from their volumes of calcula-15 tion qualification documents, what have you. I selected 16 ten. I proceeded checking their seismic inputs and I
- 17 believe there were four findings. That was four out of i
ten. We decided that with such a large number of findings 2
l 18 19 in such a small sample that we should take an additional i
a j 20 sample, which is standard in a sampling technique. I took an additional sample of ten and came up with five findings.
fa 21 f 22 In the same group of electrical raceway details
> 2 there had been a problen with the containment annulus.
l 23 24 PG&E had gone through and looked specifically at those 25 containment annulus details. They had established a program ,
b
-536-
IH Ca37 1 I further checked that program.
2 Fitting that into the tinetable, my first sample 3 was taken prior to October 16 and, in discussing the 4 findings in such a critical area, we placed a great deal 5 of emphasis in going over the calculations three or four 6 times. The result of that was that pages in the log book 7 had been changed. I pulled out fron our logs the pages a that had been changed. We saved the old pages. Those 9 findings were discussed, the original sample of ten was to discussed with Otto Steinhardt on the 27th of October and 11 I documented the meeting with Otto Steinhardt.
12 The next day -- I'm sorry -- on the same day,
. 13 the 28th, I met with Rob Sverak, from the civil design
(' 14 drafting section. I didn't have any -- well, that's not 15 true. I did have some dealings with him. You can add i
l 16 his name to that list, 1 suppose. I selected another sample 17 of ten electrical details. The way I selected that sample g
l 18 of ten was I listed ten single digits downcthe:page and 3 19 he listed in ten single digits behind that and I listed c
j 20 in a third column of ten digits. That formed ten three-a I 21 digit numbers. I wanted to make sure it was a random i
f 22 selection.
He pullad the calculations out of the files l 23 24 with the exception of one that was supplied by a Mr. Romero.
25 That same day I completed my work, which was essentially
-537-l -- - - - - , . . . , - - - - - . - - - --. ,
- 3 (hr t checking the seismic inputs. I met with Sverak again to 2 check my work. To check my work entails -- sometimes there '
3 is an additional bit of information that is not apparent 4 in the calculations. My notes here say that one or two 5 of the problems were cleared up, leaving five outstanding 6 findings.
7 Romero was consulted about his individual a calculation and he informed me that Igor Sokoloff had 9 labeled his outdated because he was currently working on to another one. That didn't affect the finding. The finding 11 stayed.
12 On that same day, I gave Igor Sokoloff a copy 13 of my work, with the understanding that he would get 14 together later with me and discuss it. On the 1st of 15 November, Dr. Chen from our office and myself met with 16 Igor Sokoloff, Otto Steinhardt and George Lenfestey to
- 17 discuss the nine findings , the nine out of twenty that
=
l 18 were labeled findings. I documented the meeting. I g is think the introduction is worth repeating. The introduction a
j 20 to my minutes reads like this: "The following statements ,
! 21 unless otherwise noted, represent verbal discussions and i
f 22 verbal reconstruction of what might possibly have taken place." In other words, the three gentlemen from PG&E were l 23 24 basically trying to reconstruct what the designers might 25 have been doing two and three years ago. As a result, it b
-538-
5 p.
As no (j ,
f 7 1: '.did not affect our findings. We were looking for something
'~
2 do,cumented a little better than that. We discussed each 3 one of the findings in detail and there was no disagreement 4 about the nine Lindings on paper. They were findings.
7' 5 Four of the nine support details would have u 6,_ exc'veded the allowable stresses if the correct structural 7 value was merely added. That doesn't say they would have
~
8 overstressed. The calculations are of a very conservative, 9 Static nature. But if you had merely put in the correct 10 value, four of those nine would have exceeded the allowable.
11 We allowed PG&E to work further on those four. There 12 wasn't a great deal of time for that. They provided 13 -
documentation to me that showed that two of the four could if bh qualified with minor changes to the engineering and,
.15 with the short time allowed, two of them could not.
~
16 So I believe our final report stated that, out
- 17 of the twenty, we had nine findings, of which two could r =
l
.j H3 not be qualified with conservative static calculations.
19 As far as their program to check containment i
j 20 annulus,~ there were a few problems with their program.
They we'ra reported in the log. I don't know if they were

d 22 reported in the report. I'm not sure about that.

25 - MR. DENISON: Fine, k..
l -539-l l
21 h, , MR. SHACKLETON: And that will be Exhibit No. 4.
2 (The document was marked as 3 Exhibit No. 4. )
4 MR. DENISON: The last area that I have documented 5
is a meeting with Stan Hanusiak on the 28th of October to 6 discuss the dome service crane. Although I wasn't involved 7 with- the dome service crane in the initial report, I believe g that it--is what we called an open item. The documentation g was really n'o t there and we could not say that we looked jg a't the documentation and it was qualified. So we left it 11 as an open item. I believe PG&E's intent-throughout their 12 mar -up stage was to close open items by providing addi-g tional documentation, for exampla.
14 So I met with Stan Hanusiak on the 28th and 15 I made the- following notes. The crane was qualified in the 16 parked condition. That would be lying horizontal. I
, p received from him both the Blume report that qualified it
=
in that condition and a PG&E calculation I received from l 18 y ig Eugene Krasnikov of civil design drafting. He told me that j 20 the crane would remain in the parked condition until it was l 21 m dified and they had designed a new base for the crane i
f 22 which basically consisted of eight large shock absorbers.
23 That was expected to be completed in about 16 weeks. So 24 they were not planning on using the crane until it had been 25 modified. They also had a qualification with the shock u
_ m
-540- ,
<C CEd i absorbers. I received that qualification.
2 So in this instance, the open item reported in 3 the earlier reports was closed with the meeting with Stan 4 Hanusiak and when we obtained additional information.
5 MR. SHACKLETON: For the record, Mr. Denison, 6 the dome service crane you are referring to is a crane on 7 the top of the containment building?
8 MR. DENISON: Right.
9 MR. SHACKLETON: That will be Exhibit No. 5, 10 the Dome Service Crane.
ii (The docurent was marked as 12 Exhibit No. 5.)
13 MR. DENISON: I think that's pretty much the
(. i4 extent of what I had to do with addressing comments in the 15 report.
16 MR. SHACKLETON: Let me ask you, do you feel 17 comfortable, then, the way, the conditions under which g
j 18 you had to work concerning the handling of comments from g 19 PG&E7 a
j 20 MR. DENISON: I think there is one note that might be pertinent, that in instances where we could not fa 21 f 22 obtain information, in instances where the people were not n
as cooperative as it might be, we left an iter open. You'd l 23 24 be surprised at how quickly they sought to fill it by 25 providing us additional infornation. So in that respect
-541-
20
$ 1 I was uncomfortable with the procedure. It seemed almost 2 that we had to label an item open before we received the 3 necessary qualification calculations.
4 MR. SHACKLETON: What is the status now in this 5 relationship? Are you receiving satisfactory response from 6 your questions from PG&E?
7 MR. DENISON: Well, there's a couple of problems 8 with our current program. No. 1, we don't seem to be able o to get documents as quickly as we r,lght want. Our remedy 10 to that has been to send our requests to Mr. G-Trge Maneatis, ii a senior vice president. The other problem we had was, as 12 reported in our November 12 preliminary report with the 13 electrical raceway details, there were nine findings out
( 14 of a sample of twenty. PG&E agreed at that point to review 15 all of their electrical raceway support calculations. It 16 was my understanding that they would be done with that
- 17 within a month.
j 18 We have a letter in our files now that says that i 19 they will be done with their review on the 30th of December.
a j 20 When I go over there Monday to ask for the calculations fa 21 I'm sure I'll get another letter. But in that instance f 22 let me point out that our January report will not be com-2 l 23 plete or it will be a big open item if that is not supplied.
24 MR. SHACKLETON: Going back to the period that 25 we were discussing originally, $he revisions that you
{
-542-
f.:
1 received to the October 21 and October 26 drafts, were you 2 required to make any changes without substantiating docu-3 mentation?
4 MR. DENISON: No.
5 MR. SHACKLETON: Mr. Denison, for those many 6 peoole who will be reading this i?vestigative report, 7 including your conments during the course ci this interview, 8 could you briefly relate to the public the type of inter-9 face that is required to do a reverification stu T such as
. to you have beer: involved in here i etween your firm and 11 Pacific Gas & Electric?
12 MR. DENISON: I'll address the period from 13 October 11 through Noverber 12; that would be our prelimin-(,
14 ary report. When we initially got the assignment we had 15 one week in which to do the work. Our main task was to 16 investigate the seismic interface. That involved PG&E g
17 supplying URS/Blume with informatiaa, URS/Blume calculating l 18 response and issue spectra to PG&E. The spectra was used i
19 internally by PG&E and by PG&E vendors, be it Westinghouse j 20 or Wyle Labs. It is a large task and we had one week in 21 which to do it.
a f 22 To come up to speed on an issue like that in one
=
l 23 week there is a great deal of personal communication that 24 is required. We used the personal communication to give 25 us the background. In no case was the personal communica-k
-543-n .: .., . ., . ,._ .c , _ . - . . , _ , _ . _ , , _ _ , . _,,
25
(" i tion used as a qualification document. When there was a 2 complete lack of documentation, we asked responsible 3 engineers at' PG&E and Dave Lang from URS/Blure to supply 4 that information in writing. That is on our file.
5 MR. SHACKLETO?i: How many people are prasently 6 -- well, let's go back to the pertinent period of time we 7 are addressing. During the month of October, you were 8 assigned to this project on October 11 and have been 9 assigned I understand for a continuing period of time up to to now, is that correct? ,
33 MR. DENiSON: That is correct.
12 MR. SHACKLETON: Can you give us an idea of how
- 13 many engineers from Cloud were assigned to the task on 14 this reverification study during the period since you came 15 on board on this project, October 11, until your first 16 preliminary report was presented, dated November 12, 19817
- 17 MR. DENISON
- Shafi Motiwalla was involved for
=
18 the entire period. Hanson Lowe was involved for the entire l
g 19 pe riod. Paul Anderson was involved for the entire period.
c j 20 pao Chen for the entire period. Myself for the entire l 21 period. Bob Cloud for the entire period. Dr. Tom Slot for l I f 22 two or thr3e days. In addition, I believe all the engineers
! 23 in our office at one time or another read the reports.
24 MR. SHACKLETON: Mr. Denison, is there any 25 comment or question that I asked of you that you would k
-544-
(?hvs 1 like to readdress to add any additional information for the 2 Commission?
3 MR. DENISON: The question'you asked me about 4 individuals I had dealings with at PG&E. The list is 5 extremely long. I can fill in some nanes for you, if you 6 like, or I could leave the list as it is. The list I gave 7 you would include all the individuals -- well, let me add 8 to the list.
9 Victor Smart, from the field, Diablo Canyon, he io supplied some as-buil' information and, although he did it not talk to me directly, I talked to someone who was on 12 the phone with him, which would be about the same thing.
13 In addition, I talked to Jim McCracken, George Maneatis,
(.
14 Bruce Norton, Dick Bettinger. There's several.
15 MR. SCACKLETON: Is there any other additional 16 information relating to the seismic reverification study
- 17 you would like to make a matter of record?
l 18 MR. DENISON: No.
g 19 MR. SHACKLETON: Do you have any additional j 20 questions, Mr. Morrill?
21 MR. MORRILL: No, I don't.
a MR. SHACKLETON: Mr. Denison, on behalf of the f 22 s
Commission I thank you very much for your comments and the l 23 24 detailed work you went through to be prepared to make 25 available to the Commission for their review your notes
