BY MR. FARRIS:
I ts O Mr. Engmann, yesterday you told me that Black & !
Veatch intends to use cross link polyethylene for something 14 15 ; greater than 50 percent of its scope of supply, is that iGj correct? i
't ,
p ; A (Witness Engmann) I anticipate that the nu aber of ,
13 cables that.would be insulated with cross link polyethylene I
- g would exceed 50 percent. i 20 0 And yoc identified the type of cross link poly- i s ,
21 .I ethylene as fire retardant? i l l

10 A Yes, I have a report that indicates the develop-11 ment and verification of fire tests for cable systems and )
12 systems components, reports 2 and 3, September 1, 1977 13 through February 1978.

6 MR. GALLO: Objection. The witness has testified ;
I 7 thEc he hasn't read the document, he is not familiar with 1
1 6 the document, and that the first time he's scen-it was, I D guess, today, f i
10 To ask a question from a document on that basis

l
- 2 A No, I'm net. I 3 Q Are you. aware of how cross link polyethylene ecm-4 pares to Tefzel as far as susceptibility to shorting in l l
l 5 flame tests?
6 A One of the things I would like to have you l
7 clarify a little bit is, flame retardant cross link poly-8 ethylene can be compounded in many different ways. It can 9 he halogenated with any one of the halogen family. Depending 10 on which one you use you're going to get different properties I ,
- 1 Flame retardant cross link polyethylene is a l
!S generic name, and when you say you're going to use that it's j like saying you're going to use a Chevrolet. You've-going I
{ 12 I M to have everything from a Chevette to a !!onte Carlo.
15 t Q Well, your -- Black & Veatch, I should say -- your ,
l !
' I 15 cross link polyethylene, are you going to have all the 17 options, or a stripped-down model?
18 A We're going to buy it so it'll pass IEEE 383.
19 The advantage of the standard is to set criteria for flame 20 retardant properties.
- 1 o Do you consider a product that merely passes 353
'a J ,
to be adequate fo.r purposes of Black For Station?
k- Es A Certainly.
- 4 0 Did you hear the question?

V INo acceptable for the Black Fox Station? '
,4
- '-p O Yes.
e i'
S ;j A Certainly.
- 3 4 Q Even if other products pass it by c grceter o
a ,
- 1 5 l'l margin you still think it's saticfactory just tc moet the l h !
3 3i minimum? l 7 l A When you're trying to select a cable conctruction l I
E i you do it on the basis of many different criteric. Dven 41 EU the flame retardant criteria has many ftcets to it, j it n
!C} Cable construction has to be colected primarily li 11 fi based on its electrical characteristics of that construction. l I'
1 12I che dielectric croperties, resistance te ground properticc
!I I Y the leakage capacities. All of these tre prinary criteric 7
il j lii it !i f for selecting the cable construction. The insulation il material is there to provide your electricci insult. tion.
t, t
M, Included with the critoria in moct power gencrat-ing stctionr c and a certcin amount of nuclear p rer gencrating S stations, are the flame retardant criteria alco, and hov 19 ;l that particular cable construction performs with a flanc M i[
! applied to it. The retardancy can be cdequately demonstratsi-i I,
l '. ' .
by pascing IEEE 383.
I L2 i There are some other properties of the insulating
- ;1 I 1.
material that are relevant in c ticme tect. I think it 1
& ! wcs notod ycstotday by it. Shon that in the uccticony it
- k. ,0,0 l was mentioned that Tcftel has a tendancy to short out faster i
6909 :
wel 8 :
1 in a flame test thLn other types of insulating materic1. l l
,e 2 Certainly this is a property that could be desirchie in a ;
i 1 3 cable conss 4ction. l 4 So as far as maintaining the criceric of ficme !
l t
5 retardancy, I think that passing 363 is an accepttble i
6 demonstration that flame retardant properties cre adequate. !
7 Q Is cost a critarion nsed in selecting a cable? ) ;
6 A Cost is a criterior. in.all of the system. l
\
\
S Q You stated that you saw a test batween cross link i
10 polyethylene and EVR?

16 8-foot tray, I don't recall exactly. I believe they ware 17 comparable.

19 would pass the IEEE 383 modified or extended test?

$[ A Yes, you did. And, in fact, if I recall my ,
b '
d response, I pointed out that the cabling that I was going
(
l ~ i-' to cpack about was the cabling that was installed in the h .3 W . field versus factory inctalled cabling insido panels. l i
T[C of the cabling installed in the field, we had ;
I t 0 !! two categories: That which would be installed i.. '.he PGOC il i and that which would be installed in the rest of the plant.

polyethylene gives off quite a bit of corrosive gases?

Ouite a o
i v i bit isn't a thing you can cuantify. It gives off corrosive j i
i gases like any other cable construction does when it burns.
O Let's compare it to Tefsel. Does it give off I 11 I I
quite a bit as compared to Tef=el?
A I already answered that question: I don't know, i
0 If you had the results of tests that indicated .
14 ',
that it did give off 10 times as much corrosive gases as if Tefzel, would you still be inclined to use cross link poly-I ethylene as your major cabling? l 17 ( l MR. GALLO: Objection. Mothing in this record 18 19 would substantiate that test exists which indicates that Tof zel is.10 times superior to the other types of insulation.

- F I- to use any other cable for Blach r Vectch's scope of supply f
.n for the Blach Tox Station? I A The halogenated compounds are used in cable j 6
construction for flame retardant properties. They are 7 1 C
additions to materials that are desirable for electrical l l
1 l
insulation. You don't select cable conctructions only on t
the basis of thcir flamz retardant properties.

10 A The test data chat I reviewed had been summarined 11 by someone who was working for me, so I am not sure whc 12 performed the tects.

14 A You have to start talking about what the 15 construction of c cable is. The out covering of the cable 10 construction to be ussd at the Blaic Fox station, the 17 jachoting materiel is chlorosufinnted polyethylene, net 18 cross' linked. The insulation acterial inside the jachot ic 10 crosc link polyethylene; cable resting on some sharp 20 projection will be resting, obviously, on its jacket 21 meterial which is chlorosulfinated polyethylene for 22 Black Fox. -

10 When you talk about the penatrations to the !
l 11 walls, I have confidence in that and that we have cpecified l
12 i as far as the rating is concerned, the chility of the f 13 firewell penetrations or the penetrationc for the 14 firewall to be jeopardiced would be news to me and probably 15 I would be more -- and probably would be more offectively ;
i 16 ;
answered by Mr. Entmann. l 17 l A (Witness Engmann) YEcterday we diccessed the ,
18 design of cable tray penetrations in floors and walls.
19 At that time I indicated to you that our design was going to 20 be baced on the application of silicona foam material 21 and that those cable tray penetratienc would be tertcd in 22 accordance uith ANI requiremente which included an ASTME-119 23

24 - i Based on that testing, I would hcVe full confidence j that the integrity of the 3 hour3.472222e-5 days <br />8.333333e-4 hours <br />4.960317e-6 weeks <br />1.1415e-6 months <br /> barriar would be maintained t

c 2 BY MR. FARRIS:
3 O Then you hcVe some concerns about tho 4 penetratienc in the firewall?
5 A (Witness Engmann) I think the.t you have to be 6 very careful that you raaintain the integrity of that i i
7 barrier and you do that by testing the application that !
i 8 you intend to use in accordance vith accepted tectc.
9 -Q The integrity of the firewall wculd be no 10 better than the sealant that you use in the area of the 1

12 A In this particular case, the vall itself 13 probably has a rating that much exceeds three hours.

david 2 to indicate that a water suppression system should be

3
- A No, I didn't because the question was not 4
being addressed to the PGCC.
5 .
O Is it your opinion that a water suppression system 6
should be used in the PGCC7 7
A No , it isn' t.
8 Q Can you explain why?
9 A I believe in this particular case a halon 10 system applied in the area that we are concerned with, 11 the subflooring is a perfectly adequate suppression system.
12 Q Does that opinion rest upon the type of fire 13 you might expect in that aren?
14 '
A No. It isn't dependent upon the type of fire.
15 O Can you give me the basis, then?
16 A Mell, the halon has been shown to be an eff ective 17 fire suppressant for all fires except deep seated fires.
18 The halon concentration, effective halon concentration that 19 we are introducing here of 20 percent is an extremely 20 eff ective concentration and so it will be an eff ective 21 fire suppressant for a fire in this area.
22 Q You don't expect a deep seated fire inthat 23 area, is that it?

A (Witness Cox) The objective of the fire hazards l

safely shut down the reactor.
8 0 Is this a comprehensive and systematic 9
analysis? l 10 A Yes, it is very cor.prehensive, 11 i, Q For the Black Fox station?
12 A Yes.
. O Can you e:: plain how you conducted this analysis 14 starting with the first step?
15 A Well, the first step in the analysis was 16 identifying fire areas by going to drawings, referring no 17 drawings of the facility, identifying on those dreuings 16 areas which are more commonly bounded, that can be 19 classified as fire areas, and this is identified 20 by a rating of a wall' and the primary reading of the 21 wall that'we initiated was the 3 hour3.472222e-5 days <br />8.333333e-4 hours <br />4.960317e-6 weeks <br />1.1415e-6 months <br /> fire wall.

14 MR. FARRIS: I am going to object to this 15 line of questioning. It is not reclly in response to 10 anything that was brought out on cross examinction. The 17 document pretty much speaks for itself and I also object 18 to the witness going through and reading portions of the 19 document. It is in evidence, I think. It has taken up 20 time needlessly.

5 0 Can you give an example of the fire where you 6 concluded that transient combustible material"was introduced?
7 A There is an example of that in the railcar 8
area, the fuel car, and which we accepted as a transient in g that arca, the possibility of a boxccr in the aree..
10 0 Can you show me where that is?
A Fire cone 1-E on page 63 of Tahic 1. Uc identified gg 12 a railroad car.
I O That is fire zone 1-B where you assumed that a 13 14 railr, cad car would be a type of tansient of combustible 15 material?
A Yes, the railroad car and the combustibles are 16 37 transient matericis.
Q How did you determine as you went from firc cono 18 to fire zone what combustibles might be in that area?
19
.A Primarily the determination was made based 20 21 upon an opinion as to whether it was possible that a transient might be left inadvertently there, or whether 22 the posibility wa: good that it wouldn't, or thct the 23 o casi n could possibly arise, it might be left there.

2 O Let's go to the cable spreading room for the 3 Black Fox Station.
i 4 First of all, how many cable npreading recms are 5 there?
6 A For two units, there are four; two cable apreading 7 rooms in -- let's say there is one cable spreading room, 2
8 they are separated by a fire barrier, so you might call it 9 two cable spreading rooms.
10 0 Can you identify the safety divisions that run 11 through -- striho that.

13 A 24 and 25. ,
14 Q What safety divisions run through fire crea 24?
15 A You make sure that 24 is on one side and 25 is 16 on the other.. Fire area 24, which is on the left side, is -
17 indicated by Mr. -- Mr. Engmann's Division -- by Mr.

8 I have been associated with reactor operations 9 enough to know that under very ctrict controls, you can 10 expect about anything to happen.
I think that in this particular case of the 11 12 cable spreading room, where we again have barricrs to prevent the access, where we have insignificant or unc=pected -- it is, 13 i
14 not a pathway for traffic, it is not c trafficwey here, l t

4 99 5 BY MR.'GALLO:
G- What criteria exists for getting a key to the 6
7 door to the cable spreading room?
A The criteria is that an employee would be 8
9 personally screened. IIis background will be screened. IIe 10 will have to be' assigned a responsibility in that particular area. IIe will have to receive his supervisor's approval to 11 be in the area, and this is primarily the reason that he 12 would get a key to this particular arca.
13 14 0 It is my understanding that he -- did you 15 testify just now that he would havo to have an assignment in the cable spreading room?
16 A Yes, he would have to have an t.saignment there.
97 Q Mr. Engmann, can you tell me what systems are 18 in Se cable apreading room?
19 A (Witness Engmann) Most of the cable spreading 20 ro m is dedicated to the tray system that supports the 21 wiring t the control room. There are several inverter rooms 22 as part of the fire creas 24 and 25, but the overwhelming 23 g amount of equipment in there is electrical, and it is g primarily cable tray and cabling.

, system,.and the cabling is essentially static. Once in ,
G place, there is no reason to displace it for any maintentnce I or surveillance testing purposes. Based on my cxperience, I 7
wouldn't anticipate any need to go in there in the next 40 .
6 I years, quite frankly. There are coveral inverter ronmo in 9 1 those two areas. Thoso inverter rooms are -- the ce;uipment 10 l in those invarter rooms ic safety relcted.
,t.
i Eowever, it tende to be fairiv reliable, fairiv --
' ~
f 12 it is capable of unattended operation, obviously it is equipment that does not need to be accessed on a dcily bacio.
It has monitoring deviccc so that if thero was a probism, in 15 would be brought to the attention, to the operator. It is ,
15 j not sub j ect to those hinds of problems on a frequent bacir, 17 I outside of some surveillance tecting interval, which ons 18
'could cpproximate monthly, I wouldn't see any reason to be in thoso inverter rooms execpt on some kind of maintenance 20 check every cin months or a year.
21 So, all in all, I would not anticipats that you 22 would cce personnel in thooe two fire areas any more 23 frequently then perhaps monthly.

cable spreading room of Black Fon?
A Well, the only pince - the only type of equipment
- ' -where I could see welding being done after the initial 5 installation would be accomplished on cable tray supports.
6 After the initial installation, because of the 7 design of the station, the fact that we design with cable 6 trays is so that m:)difications in cabling can be made in an S existing cabling tray, and because of that design concept I 10 can see no reason they would be doing welding in that room.

6 A (Witness Cox) No, we did not. And this brings up .
l I
i l 7 a point that's extremely important. That is, I'm not sure { l 1
i 0 who has read the Hazards Analysis and who hasn't, but the f; Hazards Analysis very specifically identifics what the 10 criteria was that was used to design Black Fox Station. And ti i the particular criteria for the cable sprending room is i
i 12 specific'. in the Fire Hazards Analysis, and it's cpecified
- 13 in Section 3 of our response to the Branch Technical Position.
u a From the very beginning it has been our concern ,
tg that -- and our intention -- that the design criteria for ;
1s ;
the cable spreading room be in accordance with neg. Guide '
i 17 3 1.75 and IEEE 384.
I 10 I This was submitted in November, the uholo ha::arde

t design of the Station is based. ,I have identified that we 20 j t
l have taken exception or deviated from the Eranch Technical 21 \
]i.t Position. We didn't flag that with a big red flag, saying 22 l.I 21 "Here's a deviation." But we specified what we were doing, ,

5 A You mentioned design experience.
0 Right.
7 nsider fire protection experience considerably 8 1 more than design, and I think operating experience associnted g
with the responsibility for fire protection and supervision certainly weighs heavily on thtt, and that goes back over 1 l
- 11. ,
the course of 18 and 19 years to my experience back at the 1 12 General Electric Vallecitos General Electric test reactors, in
? G which I was responsible for shift operation, and part of that responsibility uss fire protection in which I received training 15 from the General Electric Company on fire protection, and 16 also I guess one of the ways to learn a subject is you have 1 17 l to teach it, and even though I wasn't experienced at that '
18' time, I gave lecturcs to my shifts on fire protection.
And I tHnk that all contributes in experience to a point 20 where -- and it contributes to the point where I felt that 21 I could accept responsibility for firo protection.

t 5 I think, 2206 acres. The area for the University of f
6 Missouri research reactor was, for example, 10 acres. That l l
7 doesn't necessarily -- I don't consider the University of 8 Missouri research reactor facility in 'he c same context as one 9 might concider a research reactor facility, because ths 10 University of Missouri research reactor is a 10 ruegavatt.
11 That is not big compared with 1300 or so magaratts of q l
12 electrical power put out by the big power plante; but the l
- 6 13 same principles apply. It is a 10 megawatt reactor. It hac 14 maintenance, it hac fire protection, it has a cooling ,
15 system, everything applies to the big reactor is there- at the University of Missouri reactor. Sice isn't nacericl, in 16 17 my cetimation.
18 0 Size of the plant ac well as the power output 19 makes no difference in the fire protection cystem necesse.ry?
LO A Fire protection is just ac imp'ortant at the 21 research reactor facility as in the power reactor, and vice 22 versa.

Isn't this a contradiction of your underctanding, .
I 21 given the fact you are familiar with uc?

all of one division.
8 Dy test we know'that it won't do all of that, 9
but we postulated all of one division buring, but only 10 that division.
11 MR. SHON: And the normal branch technical 12-penition requirement would be to burn all of the ..

'3 say that it is going to involve a change. Whether it is f-4 going'to be a change in the fire protection system 5 has not been determined.
6 THe guidelines permit alternatives, and I 7 can't rule out the possibility that there is an alternative l l
8 sdlution to a change in the fire protection system. '
9 MR. SHON: Ms. Woodhead, you have consistently 1
10 used the words " suppression system design" rather 1
11 than " fire protection design," which is much broader. l l
12 A question still unclear in my own mind is --

1 15 WITNESS COX: No, it is not. l 16 MR. SHON: That's what I thought. I would then-17 anticipate that the iportant question would be what 18 change would be required in the overall fire protection 19 design, perhaps firewalls or something like that.
20 If you made the' assumption the staff wants 21 you to make, which is that all provisions of all cable 22 insulation. burn.
23 WITNESS COX: That's the issue, but we don't
'24 know the solution. i 25 MR. SHON: Isn't it also true that there would

18 19 A (Witness Cox) Yes , we do.

20 A Justifying in our own mind that a fire in 21 that area will not heopardize the safe shutdown of the t 22 k g plant.

i ;
i e
6996 david 4 1 that a fire in that area will not heopardize the plant, r' 2 do you intend to take any steps beyond just your personal satisfaction?
A I am having some difficulty in determining
' 4 what steps. I think logically what might occur in that --
that we will reanalyze this area and draw a conc lusion --
6 and I don't make this individually -- I mean -- well, I 7
have a certain input and responsibility. This is not 8
my decision in its entirety to nake, but I can certainly l 9
envision that collectively, Black and Vecch will 10 recommend to PSO and PSO cortainly will have input into 11 the decision that if a change is required, a change in 12 design will be ude and the fire hazards analysis in the 13 future will reficct this change. i 14 O So, at this point you are unable to say whether 15 or not you together with PSO might decide to comply with 16 the branch technical posiuion by either incorporating 17 design guidance or by spelling out a justification for 1
18 deviations; is that correct?
19 A No, we are not in a position right now to 20 say just exactly what we will do.
21 0- One more question, Dr. Cox. You previously 22 discussed welding with Mr. Gallo and explained that the 23 welding would be donc before the plant goes into operation.

1 to A 11 hat I saw was a description of vertical separatio:1 11 between divisions of some 16, IS inchos at Browns Ferry 12 versus the vertical separation distance of three foot 13 required under IEEE.384 on Reg. Guide 1.75. That is what I 14 wne basing my testimony on, yes. ;

18 MS. WOODHEAD: I withdraw the question.
19 That's all. That's all questions for both 20 witnesses.
MR. SHON: Ms.11oodhead, if indeed as these 21 22 witnesses seem to have seen telling us, at least for the
(' cablo spreading room, it doesn't matter which of the two 23 pr poned fires one uses cs the design basis, as.far ce the 24 a tual phycical design of the plant is concerned, then why is 25

l I mean if it coecn't make any difference in the i 3 !
4 hardware, why is it so important to have the design bceis .
1 5 fire of one kind or ancther?
g MS. WOODHEAD: I don't believe that was the l testimony, Mr. Shon. I believe Dr. Cox said that the present j 7 l 8
fire pr tection design that he has postulated in his fire j l
g hazards analysis would acccmmodate either type fire, and I 10 believe the Staff has verified thct the hardware or uhatever yg the design is, vould accomnodate either kind of fire. But 12 I don't believe Dr. Cox naid that there would be no difference 1
in what might be necessary for an electrical fire versus to.

22 23 the plant?
l MS. WOODHEAD: Mr. Shen, I am sure vou are aware l 25 l
- l. I i-1 1
ar3 7000 1 . that the technical specifications and the design and e '2 commitments of the Applicant are enforced by the Staff, 3 and thic commitment is an important part of that ability r
- 4 to enforce these things, these designs and the criteria 5 which they commit themselves to, i 1
6 In the event they are not committed to accommodate 7 an exposure fire in the cable spreading room, it would be 8 permissible in the future for them to remove those fire I i
9~ protection systems in the cable spreading room which would l l
10 be excessive over the electrical fire.
11 MR. GALU3: Mr. Chairman, I would like to respond l l
12 to that.
i 13 I don't know where counsel gets the notion that l
14 once a fire protection system has been reviewed and approved 15 by the NRC Staff, that certain fire protection systems 16 wit 511n the overall cystem can be removed at olr caprica 17 o,ce that system has been reviewed and approved as a require-18 ment of the applicable license, and the changes can only be 19 made in accordance with NRC approval under the technical 20 specifications of the operating license.
!G. SHON: Mr. Gallo, on the other hand, if indeed 21 y your present design,for example, for t'.ie cable spre'ading
' room will accommodate an exposure fire as well as an 23 electrically-ignited fire, why not simply say so? I'hy 24 15 should there be any resistance on the part of the Applicant
t <
l ar4 '7001 l 1
1 to perforr.ing this.analysic, stating it in ALA?J., the .
2_ -design basis fire to be an exposure fire?
3 MR. GhLLO: 3ecause the. experts on my side of j e
4 the table say it is not logical to talk about a design l
?
t 1 basis fire in terms of exposure fires, because ycu can't I 5 i define an exposure fire: That follows the line that you 6
y pursued yesterday with Ms. Woodhead, how many -- how large 1
an. exposure. fire? What is a combustible? Gaeolins, wood, ;
8 I
e paper? And how much, what quantitv? I, ,
\
l 10 So it is more logical to do what the witness said I
~1 gg he did in this case, which is to identify the conbustibles. ,
i Look at it from the standpoint of transient 12 t combustibles, and then use that as a design basis fire.
93 14 Thtt ir the logical basis that we have used in the cable spreading r Om. It is true we have the suppression systems 15 l and the other firc protection systems that would accommodato I 16 the complete type of fire which they characterica as an 37 10

4 gg MR. SHON: The design bacis fire abant whi.ch we are talking assumes that the suppression system does work, 20 s y u v ul n't have any change in that?
2f MR. GALLO: -That's right. There was no credit 22 23.

still a little unclear in my mind, what we appear to be i*

, g it that correct? Other than sinpiy the Ocmbustible insulation.

11 MR. GALLO: Chat's right, and in that inctancc,.
12 Mr. Shon, the fire analycis report for Blach For for ths 13

g s and giving that as the design basic? It doesn't coct you 22 anything,.it doesn't de anything to the decign of the plant, g

l 1 got to where they were. We have yet to hear the logical l 2 basis for the Staff for their position.
3 In this instanca it is true that the -- if you 4 are going to use the tenu exposure fire, that the apparatus 5 there are sufficient, the fire wall is there, the three-6 hour fire wall.
7 MS. WOODHEAD: Could I explain one nere thing, !
1 8 Mr. Shon, about our view of the nececsity of the commitment l
9 at this point?
10 We have not completed our in-depth review of i 1
3g the fire hazards analysis. We have as a quick look, looked 12 at the part which deals with the cable spreading room, and l
13 it appears at this point to be able to accommodate any kind of fira, so that in that respech Lhe design basis 14 fire w uld be irrelevant. But since we have not completed 15 nr ntire review, and an adequate fire protection system 16 g7 ic a comprehensive whole, we feel the necescity now to hcve a mmitment to thic kind of fire in the event that we find 18 something amiss further on in our more in-depth review.
19 If we are limited at this point, we are in a 20 quandary later on if we do find some serious omission or 21
. err r in the analysic.
22 MR. SHON: Yes, I realize that we are speaking g ;
g only to the cable spreading room at this point, and we have been assured that there are some other places where

10 EXTtMINATION BY THE BOARD 11 BY 11R. SHON:

Q I think it was Mr. Engmann that mentioned that in 13 having these plastics for insulation purposes, various halo-14 gens could be used for fireproofing plastics and that 15 bromine and chlorine were often used, and that the amount 16 of corrosive gas given off by the brominated plcstic was 17 rcther less than thct by the chlorinated plastic. Is thE.t 18 correct?
19 A (Witness Engmann) That is the information I 20 received from several of the cable vendors.
21 Q Are you specifying brominated plastice for all of 22 these, or do the manufacturers simply get their choice?
23 A I feel that the specification of IEEE 383 is sufficient specification construction from a fitme retardant 25 point of view; compoundic.g of cable insulation is a vcry i

7007 ar3-1 exposure fire, and that all of the cable -- is spacing 2 between cable trays important if in the design basis 3 fire assumption all of the cable burns?
n 4 A The course of action led us to where we 5 got was to loch at the combustibles present. If the 6 combustibles present were confined only to cable insulation 7 material itself, then the only source of energy that could )
8 ignite a fire would be electrical ignition. Within I 9 electrical ignition of the cable insulating material itself to we have evidence at hand that supports Reg. Guide 1.75 11 that says that separation is important, and one can conclude 12 the propagation of fire from one division to another.
13 I think that answers the first part of your question.
14 If you would restate the second part, I might address that )
l 15 one.
16 0 In the caso of the design basis fire, where an 17 expocure fire is assumed and all the cable is assumed to 18 burn, is spacing between the cable trays of any importance?
19 A If one would choose to use spacing instead of 20 barriers, then you would have to increase the spacing over 21 those explicit criteria offered in Reg. Guide 1.75 to assure g2 that the multiple divisions did not btrn, given en exposure
' 23 fire.
24 At least that appears to be the results of the 25' experiments at Sandia, that the vertical separation dictance
i 700P i ar4 I Eut as I understand uha precepts cf !
1 would r.ot be adequa te . !
2 the Branch technical position, if you do have divisicns 1 3 that you have identified as redundant for certain critical I 4 safety f actions, then you shculd put barriers in there. !
t 5 If you put barriers in there, then the argument >
I 6 about how much .cpace or separation is sufficient beccmes t 7 academic.
8 0 The particular civisions that we were talking. I S a'.>out thic morning, heuever, are not specified ac redundant, l t,
10 were they? .
I 11 A The primary rodundancy is achieved in the safety j 12 cystems between Divicions 1 and 4 and 2 and 3. Additional .,
I i j;3 redundancy for both safety purposes and.for availability i 1
34 of the plant is achieved between Divisions 2 and 5 and 1 and 4; IS ,
but the redunde.ncy that is achieved primarily bet'. teen 1 and 4 16 and 2 a id 1 is more than sufficient for the cLfc. shutdown cf {
the plant, 1/ -
18 O It was mentioned this mornina rather as un cside i
39 that the cabling to the ramote shutdown panel board was
.0 largely Division 1. Does that maan that there is not 2,a in Division 3 redundancv there?
- {
22 A The design of the remote shutdown nanel or
'- that system that is called the remote shutde.:n svstem is i 23 - ,
4 largely within the scope of design of the General Electric l i
25 company, and I think the cuestion more proceriv may be

i f
, i i I
-ar5 7009 g' addressed to them.
Uhat I'hnov of that design is that it ir 2
.3 Primarily Division 1. There is little or no division to r
4 2 or 3 or 4 instrumentation control or indication on that i 1
board.
5 0 And can you say in any way how a proper redundancy 6
is achieved with a single division? It just doesn't seen 7
8 r asonable offhand. l nk you have to address the functicr. of the 9
rem te shutdown panel. I believe that currently we are now 0
positing single failure and/or-accident in conjunction with t'.ne necessity to abandon the control room.
0 I see.
13 You are arsuning in effect that a single failure 14 wouldn't. occur at the sane time in Division 1 as a requirement l 15 to abandon the control roon? !
16 A Ac I interpret curren design objectivest it F7 i does not include the necessity of assuning a single failure I or an accident in conjunction with abandoning the control room. l l

Introduction !-
- 7. The fire that occurred at the Browns Ferry Nuclear facility in Alcbama in fiarch,1975, mainly- affected electrical cabling and equiprent. After this event, the NRC undertcok a substantial upgrading of fire protection provisions at nuclear power plants.
The staff made a thorough study of the Browns Ferry fire; dcycloped licensing requirements for both new and operating plants; and comenced systematic fire protection review of all licensed nuclear power facilities. The results of the study, mentioned above, were published in NUREG-0050, "Reconuendations Related to the Browns Ferry Fire," February,1976. Based on the conclusions of the study, the staff developed an extensive set of guidelines for fire protection considerations in new plants during 1976. These guideline: were issued in the Stand-ard Review Plan as Branch Technical Position (BTP) ASB 9.5-1 i and later as Regulatory Guide 1.120 for use by the industry.
In addition, the.following NRC Fire Protection Guidance Documents have been issued:

Although the guidelines of the Branch Technical Position provide preferred guidance for fire protection programs, alternative
~
fire protection guidelines are identified in Appendix A. The alternatives apply to areas where, depending on the construction or operational status of a given plant, application of the guide-lines could have significant impact, e.g., where the building and 7,8,9-5 E

- 10. The staff position, kuted in Regulatory Guide 1.120 and Branch
- Technical Position ASS 9.5-1, Appendix A, on fire ret.irdent insulation for cables used in nuclear plants is
- " Electric cable constructions [in safety-related crees] should, es a minimum, pass the current [1974 editien) IEEE Standard 383, [IEEE Standard for Type Test of Class 1E Electric Cables, Field and Connections for Nuclear Generating Stations) flame test"; these tests are used to screen cable insulation for fire propagation properties. The l
IEEE Standard 383 specifies 70,000 Btu fire tests. The staff retained the Standards of IEEE 383-1974 based on tests by general , l laboratories which confirmed its adequacy. The Black' Fox commit- -
1 p
ment test uses the 210,000 Btu (NELPIA) fire test which exceeds !

\ \
laboratory conditions. l l 1
s During 1975-1977, several' tests were perforad at Sandia i Laboratories in New Mexico. Sandia conducted a cable fire j test with a cable tray configuration consisting of two sticked columns of seven cable trays each to simulate one safety di- !
1 vision. Other cable trays were previded to represent a second safety division. These cable tray divisions were separated r based upcn the guidelines of Regulatory Guide 1.75 for open
('
plant areas; i.e., five feet vertical and three feet horizontal spacing betrecn divisions. The tests were initiated by two different means; one type used internal electrical heating to initiate the fires, while the othar type used propane burners to produce a sustained fire (expusure fire). The tests were performed without a fire suppresrion system. Fire propagstion did not occur .for electrically initated fires; however, an exposure fire initiated in one of the bottom cable trays resulted in fire propagation from one division to the other. j The tests demonstrated that a fully. developed cable tray fire can propagate to adjacent cable-trays. The results also show
(
' that a fully developed fire in 14 trays can propagate across the five foot' vertical separation between divisions.

l The staff position accounts for the possibility of IEEE-383 cables '
propagating a fire in a cabic tray, Cable separation' guidelines and fire retardant cables are not E intended to be sufficient alone to protect against exposure ,
l fires. Additional fire protection measures are required by ?!RC.
These additicial fire prttaction measures include fire barriers between redundant safety division cable trays, autcmatic fire t-
. detection systcms; automatic fire cxtirguishing system.s, such as sprinklers in plant areas of high cable density; bcckup fire sup?re:sion capability (fire hoses and portable extinguishers), ;
-administrative procedures and controls to minimize fire hazard:
due to poor' housekeeping or to plant maintenance activities; and fire brigcde training and drills to assure adcquate respenst .
i to fire cmergco:ies. The additional fire protection measure.. :
3 contained in Branch Technical Position ASB 9.5-1 and its Appendix A, and in Regult. tory Guide 1.120 do not infer that complete protection is afforded by use of the IEEE-383 and Regulatory .
t Guide 1.75 guidance. Rather, they serve to supplement and di-

}
3S4-1974, " Criteria for Separation of Class lE Equipment and Circuits."'which is adequate for electrically induced cable ,
tray fires. Regulatory Guide 1.120, and Branch Technical Position ASB c.5-1, Appendix A, address both exposure and elcetrically indu:ed fires. The Applicant has cenmitted in his:" Fire Haz6rds Antlysis Construction Penr.it Stage

other:
a.- In the cable spreading rooms, the cable tray separation distances, both. vertical and horizcntal, will be in accordance with Regulatory Guide 1.75 and IEEE Standard 384. Safety divisions 1 and 4 in one cable spreading room will be separated from redundant safety divisions 2 and 3 in the other cable spreading room by a 3-hour fire barrier. in .accordance with Regulatory Guide 1.120,
- Position C.4 and C.6 and Branch Technical Position ASB N~ 9.5-1, Appendix A, Sections D.3 and F.3. Thus, a fire ,
in one cable spreading room will.not prevent safe shut-down of the plant, since the redundant cable spreading 7,8,9-11 ,

- Design Criteria and Safety Evaluation (TAC-4599)" memorandum l
. from V. Benaroya to R. Stright, dated July 7,1978, which we I incorporate as part of our testincny. The tests were per-fcmed for General' Electric at the University. of California research facilities. These tests consisted of using the l EWR-6 cable configuratien and Tef:e1 cebles representctive of the Black Fox design er,d inst:11ation to show that a fire in one of the esbie trains will not damage the adj: cent trains

" Power Generation Control Compicx Design Criteria and Ssfety Evaluction," Revision 2, V, arch 1978. Even though the tests showed that for the Bicek Fox type configuration, a fire l would not propagate horizontally along the test cable and, therefore, could not affect adjacent cable tecys, to ccmply with tha defense-in-depth philosophy, GE will install a fixed manual halon fire protection system. with a concentra-tion of 20% and thennal and smoke automatic detectors in

For fire protection evaluation purposes, the tervinttien cabinets for the PGCC design are similar to cabinets in other piant designs and were not te:ted. We required, as part of the TGCC, a mear.s for datec-ting fires in those termin?, tion cabinets which contain redundant safety divisions. The applicant is responsible for providing product )
of combustion detectors at the top of each cabinet which contains redun-dant safety cable divisions to detect a fire in any bay. Each cable division vill also be separated by c cett.1 fire barrier within the tcitination cabinets. The detectors will alt.rm locally for thare l cabin:.ts loc.ted in the control room.

l It is.our opinion, as well as our consultants', Gage-Babcock and Associates, Ix., that the PGCC design is an acceptable alternative to the guidelines of Regulatory Guide 1.120, specifically, Section-C.6.b in regard to fire protection in the floor sections of the PGCC area in the control room complex, tnd Section C.4.a in rest.rd to cable tray fire barrier design, construction, and separation and, l's' therefore, is consistent with 10 CFR Part 50, Appendix A Criterion 3.
These comitments by the applicant will materially reduce the proba-Hlity anc consequences of the type of fire which took place at Browns Ferry. Therefore, the staff found the design to be acceptable 1
and meets the intent of General Design Criterion 3.

Contention 9 ,
- 12. The Applicant has submitted extensive inferration in its " Fire liazards Analysis Report" concerning its proposed fire protection program. The analysis covers all safety-related areas of the plant and fire protection systees for these areas. The staff presented its evaluation and conclusions with respect to the fire protection system for Black Fox Station, Unit Hos.1 and j 2 in Section 9.6.1 of the Safety Evaluation Report (SER) dated !
June, 1977. The Safety Evaluatian Report states that there is sufficient design flexibility in the plant to alleu future design changes if required and that "the design (of the fire protection system) as presently proposed, maets ' General Design Criterion 3, e ' Fire Prctection,' end applicable guidelines in effect prior to N issuance of Branch Technical position ASB 9.5-1, and Appandix A, thereto, and for the construction pemit stage, we find it accept-able." Therefore, we could defer the detailed fire protection system revier until after issuance of the construction permits.
Our review was based on the infomation and comitments submitted in the PSAR, including all amendments and letters, which wet e sufficient to pennit us to make a finding pursuant to 10 CFR 50.35(a), thct the fire protection system design is adequate for the level of review necessary at the construction pemit stage. The basis for this
/"
conclusion is as follows:
7,8,9-16
1
- a. The applicant has described the princip:.1 architectural and engineering design criteria (plant structures, and system I design parameters) with respect to plant fire protection, and has identified the major features or ex.ponents incor-porated therein with respect to the plant fire protection systems for the protection of the health and safety of the
. f public.
1
- b. The presently designed facility has sufficient design flexi- l bility in _the area of the detection and extinguishing systems to alicu implerentation of cny design changes that may be' necessary to assure com^11ance of Black Fox Station, Unit flos.1 and 2 with Appendix A to the Branch Technical Position l ASS 9.5-1, and Regulatory Guide 1.120 and which may renscnably N
be lef t for later consideration.
- c. There are no safety questions associated with the features of the fire protection system that requires cny research and developme.nt.
The fire protection rescerch being perforced for f4RC is confirma-tory in nature. -
d.
On the basis of the above, there is reasonable assurance that:
(i) any additional protection requirements regarding the fire protectio'n system will be satisfactorily resolved at or, before the latest date stated in the application for completion of construction of Black Fox, Unit Nos.
1 and 2.

(ii) with respect to the fire protection system, and tahing t
inte consideration the site criteria contained in 10 CFR Part 100, the proposed facilities cen be censtructed ,

FGCC Fi e T rot etion The Powar Gent: ration Control Compicx (PGCC) is a prefabrication con- --
cept for routing and installing cabling for the control room of boil- '
ing wt.ter reactors. PGCC consists of three major assembles: (1) a set of steel floor seccions, (2) a set of termination cabinets, one for c:ch floor section, and (3) a set of interpanel cables. The steel floor sections contsin raceways to provide routing tnd sepa-ritior; n' All interpanel cabling. The coerator panels and the the signsi caan ticning panels will be nounted on the ficar sections.
These ptncit arc not cor.siderec a pcrt of PGCC and will be reviewed on a plan:-by-plant b; sir. The tereinttien cabinets provide the intef6ce N .een tne field installed cabling and the factcry in-sttilcd cibl:: in tf e floor sectiere. The fire protection system fer thc ~7JC rill consist of fire detection ar.d suppression for the ficer scctians and fire detection for the termination cabinets -

con.: . with our evciuation and conciations.
Gene rl Electric has performed fire barrier tests for the ficor sec-tions of PGCC at the University of Califorr.ia lacoratcries in order to de~cnstrate th3t a fire in ene ccble safety division wruld not prrpa; ate or cause un:.cceptable damage to a redundant cable safety disision in an adjac;nt raceway. The test fire and acceptance cri-teria were tgrced to by GE and the sccff before the tests. The tests were perform?d to deconstrate that PGCC had acceptable fire barriers between cat.le divisiens. A description of the fire tests and their results are contained in the PGCC Topical Report. Conservative fire tests were cond"cted by placing conbustible material within one ca-ble division raceway and removing floor plates from each cnd of a
- floor section to provide ventilation. These tests were performed with no fire suppression throughout the duration of the tests. The fire test results showed that (a) non-Tefzel cable resulted in a fire which propagated partially in one raceway and produced consider-l able smoke; and (b) Tefzel in:ulated cable resulted in little or no
\s. fire propagation in the raceway and considerably less smoke genera-7,8,9-24

tion throughout the test. t i
At our request, General Electric has included provisions for a ges ;
' fire suppression system (Halon 1301) in the floor sections for all l I. PGCC configurations. iThese systems will be automatic for non-Tefrel ,
insultted cable be:.ed plants and manually initicted for Tef:e1 insu-lated cable based plants.l The Halon su; ply system external to the ficor sections will be the responsibility of applicant referencing l PGCC. GE has provided acceptable interfaces for the design of the Halon system. GE has also provided quici. opening covers on the ~'
floor sections for manuti fire fighting purposes. i Fire detection for the ficor sections will consis t of two thermal and one product of combustion detector in each lon;itudinal raceway.
Tnese detectors will be cor.nected in a zoned configuration to indi-cetc locttion of a fire by floor sectior. Appliccnts referencing PGCC will be re.ponsible for the zoned system external to the PGCC.
Ter fire protection evaluation purport , the termindtion cabinets for the PGCC design cre sim.iiar to cabinets in other picnt designs and were not te;:cd. We rcquired GE to provide a means 'er detect-ing fires in th:se termination cabincts which contair re andan: stfety divi:d e- GE prov.ided product of ccmbustion detectcr3 a+ th2 top of
,_ cach car. net which contains redund r.t safety cable divisions te e.t:ct a fire in any b y Each cable division will also be scr-

If the cabinets arc located outM e2 tne I contral roon , ch c :ne catectors rilil be connectea to the main centrol C'~~4 rc. : .a,,_ D r *. *m' ' ' '.'. '. t'..*. .9ET I..
T!.a termination cabinets will also be readily accessible for manuel fire fichting by means of hinged doors on the front of each cabinet that will be kept unlocked for quick ccccss.
All panels, consoles, and cabinets other than the termination cabi-nets will be evaluated for fire protection on a plant-by-plant basis since they are not included in PGCC Topical Report.
Based on our review of the design basis and criteria for fire protec-tion, interface information and the fire tests, we conclude that the '
proposed design is in accordance with Regulatory Guide 1.20 and General Design Criterion 3 and is, therefore, acceptable. ,

9 A That's a direct quote, yes, sir.
10 MR. SHON: Mr. Gallo, it might help us all if you II made certain to identify the Appendix A you're talking about 12- directly. There are two Appendices, both called A, involved ; .

4 BY MR. M M:
5 Q You don't have an opinion on that point?
6 A (Witness Giardina) As I said, Mr. Behn is the 7 expert. 'I am not. My opinion would bear no relation to the 8 caso. The Guides were developed by a fire protection engineer, 9 and an interpretation of what an exposure fire is should be 10 left to the fire protection engineers.
11 O I see. Are these fire protection engineers at the 12 HRC or at a non-governmental organination?
- 13 A The guides were developed by a fire protection 14 engineer at NRC, but we do use consultants to review the 15 Fire Hazards Analysis, and their interpretation is just as 16 good as the NRC interpretation.
17 Q All right, Mr. Behn, let me ask you:
la Do you see the term " exposure fire" defined in 19 Criterion 3?
20 A (Witness Behn) No, I don't, but I think the design El basis fire is an exposure fire.

" Definition," and I wonder if -- Mr. Giardina, first -- you, ,

S O Well, are you reading from the definition of the f i
4 term design basis fire?
5 A Yes, I am.
6 Q Do you consider that as being an exposure fire?
1 7 A Yes, sir. ,
C Q Now, how large an exposure fire do you believe 9 this definition contains?
l 10 A An exposure fire is a concentrated source of fuel j 11 that can be moved around the fire area and result in the most 12 damage to the area.
l 13 0 Well, how much fuel do we need?
l t
14 A Again, it depends on the fire area and the cable j l 1
15 tray configuration. A corridor that may have redundant trainsi 16 in it may have four or five soiled laundry carts in it, whereae l
t? a small room that has redundant trains, the possibility of 10 i using these in the small room is remote, because they won't 19 fit. So we consider another exposure fire, such as the 20 flammable liquid.
21 Q So am I correct that a person would have to look

3 As defined by Mr. Behn, do you apply that e l 4 definition to the control room?
5 A (Witness Giardinal Yes, that would be applied !
l 6 to the control room.
7 0 Do you presume that in connection with the control 8 room, that the design basis fire will burn every combustible l 9 wire or the insulation of every combustible -- I'm sorry, 10 let's try again -- that the fire will burn the insulation 11 on every wire, and also burn every other combustible within 12 the control room?
13 A It will be assumed that -- in the evaluation 14 that the combustibles in the room would burn.
15 0 Is that what you -- is that what was assumed 16 for purposes of the review, the general electric control 17 room, called the PGCC?
18 A I did not conduct a review of the PGCC. It 19 was reviewed by one of the other reviewers, and it is my 20 understanding that they conducted a test to justify their 21 procedure, to show that under the operating condition that 22 they would have in the plant, that the system would not 23 propagate a fire within the PGCC complex.

9 O Did that fire consume every combuctible within 1
10 the control room? ,

14- A Could I have the question read back, please?
15 MR. GALLO: I will repeat it.
16 BY MR. GALLO:
17 Q I guess first -- well .my question is: if 18 you are going to assume that everything, every combustible 19 within a certain fire area is burned and consumed by fire, 20 what difference does it make if you call it an electrical 21 fire or an enposure fire or some other type of fire?
22 A Just that the' initiating device -- I don't believ5
23 . Black Fox .has considered an exposure fire if there
- j. 24L was no transient load on the floor.
25 .g. Then apparently the disagreement isn't over
7042 l
l 1 l david 3 terminology; it is whether or not it is proper to 2
consider transient materials in a particular fire cone. l 3
Would you agree with that?
4 A .Yes, that's true.
5 Q So that perhaps we can abandone this semantic 6 1 disagreement over whether it is an exposure fire or an 7
electrical fire and focus on whether or not transient 8
materials, transient co=bustible materials are appropriately ;
9 l located in the room or in the fire area.
10 A We have no gucrantee whether about the location l
11 !
of transient combustibles in the fire area.
12 i O Isn't it true in the fire safety analysis !
l 13 report that a fire area by fire area analysic is mcds to deter
- 1 14 mine what combustibles are to be expected to be 19cated in (
15 [
that particular fire aroa?
10 A Inctalled cc:tbustibics, yes; trancient combustibleu, l 17 l (
no. -
0 Hasn't the applicant done %at in this' case?
10 A He has considered the installed c n % % 1E 20 J in his analysis, I believe. 1 21 0 Did he not in some inctances identify 22 .
transient combustibles also in connection with particular 23 fire areac?
24 A He may have, but again an crposure fire has a 25 ~
strong concentrated source of fuel, and I believe in his
_. l
- w_ - _ _ _ ___
7043 1
devid4 analysis he spread the exposure fire out throughout the 2
area of the fire ~ zone.
3 O I thought you agreed with me that we don't 4
have to worry about labeling the fire; what we have 5 l to worry about is whether all of the combustibles in the 6 l area were consumed. )
7 l A Right. I believe that Black Fox, when they 8
did not consider an exposure fire, it was not credible 9 i for them to lose the cabling in the area.
10 0 cabling where?
11 A Wherever it is installed.
12 O Have you read the Black Fox fire safety 13 analysis report?
14 A Yes, I have.
15 0 You have? Have you heard the tectimony today 16 with respect to the cable spreading room concerning the 17 3 hour3.472222e-5 days <br />8.333333e-4 hours <br />4.960317e-6 weeks <br />1.1415e-6 months <br /> firewall that separates redundant safety divisions?
18 A Yes.
19 Q Do you still believe that it is important to 20 talk in terms of an exposure fire rather than trying to 21 determine whether or not combustibles, transient combustibles 22 should appropriately be included in each fire area?
23 A Well, they have redundant cable spreading rooms, 24 so it is possible to lose the cable spreading room and 25 still shut down the plant safely with the redundant
7044 david 5 1 system.
2 .Elsewhere out in the plant, I believe there are j 3 places where there are redundant trainc.
r 4- 0 But you did agree with rae that the applicant t
5 should review the various fire creas in their determination j 6 of the combustibles that should be reasonably in the 7 fire area; is that correct?
8 A Yes.
9 0 Once he does that, includes that judgment in i
10 the fire analysis report and submits it to the NRC, I 11 ascun.: a review is rade by the NRC; correct?
12 A That is correct.
e 13 O And if you disagree with the judgment on the 14 number of combustibles or the amount or type of corobustibles j i
- g in a particular fire area, I would expect tha.t you would j i
16 cend back a contnent indicating that? f 17 A That is correct. {
18 0 You haven't done that yet for the Black Fox 19 ctation, have you?
20 A Review the fire hazard analysis?
0 No, I asked whether or not you have sent back 21-22 a particular cercuent to the utility indicating that in certain fire areas the combustibles were not properly 23 ;
}
identified in your judgmsnt.
24 25-A (Witness Giardina) That is true. We did not i

4 A It does have a value in the evaluation.
5 0 And it has been presented in the form of our 6 analysis report, correct?
7 A That is correct for the fixed fire combustibles.
8 0 Is your testimony still the same on this point?
9 Let me turn to it. Pago 17, paragraph B, you indicato, 10 "The presently designed facility,' meaning the Black 11 Fox statim - "hac sufficient. design flexibility in 12 the area of detection and extinguishing systems to allow 13 implementation of any design changes that may be necessary 14 to ascure compliance of Black Fox station with Appendix 15 A to branch technical pocition 9.5-1."
16 And you indicate Reg Guide 1.120.

Are you familiar with the term called

A I am familiar with the tern, yes.
16 37 0 Ic it your understanding that there are certain 18 accidents postulated for reactor design that have to be gg designed against?
20 A Yes, sir.
21 O Is one of those accidente loss of collant 22 accident?
" A I understand it is, yes.
23 24 0 Is the cause of the accidnt ever a consideration 25 in de> ermining whether or not the accident has to be
7049 david 2 1 designed against?
f~ 2 A In some cases it is, yes.
3 0 Let's take the double-ended pipe break for the
\' 4 loss of coolant accident; does the NRC staff look to 5 see if the accident can be caused in the facility, or do 6 they just assume that it will be and go from there?
y MS. WOODHEAD: I object. It is outside the 8 scope of the testimony.
9 CHAIRMAN WOLFE I'm corry. I can't hear you.
4 10 MS. WOODHEAD: This line of questioning g; concerns design basic accidents; that is not within the 12 scope of the testimony.
' MR. GALLO: Mr. Chairman, I will try to connect t 13 14 it up. If I can get some basic ground rules with the 15 witness on what the design basic accident means --
4 16 MS. WOODHEAD: Mr. Chairman, fireprotection is 17 net a decign basis accident; it is irrelevant. ,
gg (Board conferring.)
19 CHAIRMAN WOLFE LEt me cee where Mr. Gallo is 4
20 g ing. Let's see if he can make his goal.
Objection. overruled.

_ , m , . _ _ . . . - _ . _ . - _ . .
f 7050 david 3 1 that the type of loss of coolant accident called a
, 2 ' double-ended pipe break was just assu aed to occur, rather l
~
3 than the staff looking to see under what circumstances
~
4 or how it might occur?
5 A I don't review the loss of coolant accident.
6 O Do you know the answer to my question?
7 A It is my opinion that on that condition where a pipe break occurs, we do not consider what causec it, 8
i Isn't that the analogous siuuation with 4 g O 10 rctpect to the design basis fire? You acsume that the ,
1
- fire is going to wipe out all of the combustibles in the area; therefore, we don't need to know how the fire !
12 C 13 started.
A No, I do not think that is analogous.
14 O Mr. Behn, what about you? j l 15 l
A (Witness Behn) No, I don't.
16 0 one last shot, Mr. Behn. j 37 l
gg We assume that all of the combustibles in a
- g particular fire area ignite and are consumed and are burned; won't that in effect cotopletely destroy all of the cabling 20 i
in that area? l 21 \
g A- That's true. l 23 0 And won't that occur even if we assume that the co:tbustible is the insulation from the cabling? l 2/,

7051 david 4 1 an electrically initiated fire to cause the most severe 1

4 O Do you believe that reality is part of 1
I 5 this definition of the design basis fire?
6 A It is the criteria that we used.
7 Q Do you believe it is realistic? :
8 A Yes, I do. l 9 O Do you think it is realistic to not take 10 credit for the automatic suppression system that might be i 1
- g in a particular area?
12 A The suppression cystems have been known to fail.
e n Q Do you think it is realistic to not take j y, credit. fire brigade, and fire extinguishing action 15 that might be takon?
16 A We provide a defense in depth for this analysis 97 and it has appropriate backup with the fire brigade, fire protection and early detection, so we can lose one 18 99 -
and still have appropriate backups.
Q Let; me ask: do you think then that it is 20 realistic to lose all of these systems for purposes 21 y of this fire definition?

( 4 Q Mr. Behn,withrespecttothecablespreadingroom,f 5 I believe it is your judgment int a fire analysis should 6 include transient combustible material; is that correct?
7 A (Witness Behn) That is correct.
8 0 How much transient combustible material?
9 A I would say that is a five can of fla:snable 10 liquid.

CHAIRMAN WOLFE: What did you say 1t was? l 19 ,
20 A can of what?
WITNESSIEHN: Flammable liquid.
21 22 BY MR. GALLO:
0 So it is your feeling because you observed 23 I
a y this one instance which had this five gallon can of flan:mable g :; liquid, that that is a sufficient basis to now determine
,i l1
~
7053 1
david 6 that that is representative of what you might find in 2
a cable spreading room generally; is that correct?
A (Witness Behn) There is a variety of materials
- As I said before, you can find in a cable spreading room.
5 I found a gas welding outfit, class A material, wood motsrial, 1 6 boxes. And I considered a variety of materials.
l 7 Q I am trying to find out which one you would 8 select as a design basis for the cable spreading l 8 room; I think you told me it was a five gallon can.
10 A I believe that is the figure I would use. l l
II O And that is a five gallon can? I l
12 A Yes. One of them. l
' 13 And in all of your observations, you only found O
14 the five gallon can once; is that correct?
15 A That is correct.
16 0 Mr. Giardina, are you familiar with the so-called 17 Hanauer report NUREG 00507 18 A (Witness Giardina) I have read it.
19 0 Bave you made any comparisons between the 20 findings of that report concerning the Browns Ferry cable 21 spreading room and the one that would be designed and 22 constructed at Black Fox?
23 A I have personally not made any co:nparison between 24 %e two .
25 0 Let me ask you this, are you aware of whether
1 7054 )
I, 1
david 7 or not Browns Ferry had a firewall separating redundant f 2 i j

14 (Pause.)
15 On page 2.5-4. l l
15 0 2.5-4.
17 A Yes. Section 2.5.6, electrical. My concern here I a
ja would be all four divisions being in one area.
19 Q How do you get tnat interpretation? f k
20 A The second to the last sentence, cables divisions l 21 1 and 2'will be routed in cable tray conduit and cables 22 for. divisions 3 and 4 will be routed in conduit. I am 23 under the understanding that one division is cable trays

MS. WooDHEAD: I would like to object at this I 14 i time. Mr. Behn is being asked to give a review, a Staff ,

I don't see any unfairness.
1 3 I think it is very helpful that we are clarifying the record j 4 as to what the Staff concerns are.
5 I have no objection to some MS. WOODh'EADl:
C explanation by Mr. Behn of some of the types of problems l
7 that be has encountered to give the Applicant an idea of 4 1
8 what the problems are, but to hold him to a commitment on i the record of his written analysis which is back in the !
i 10 office, which is subject to Staff review and consultation, is j 11 highly inappropriate and objectionable.
12 CHAIRMAN WOIEE: I think not. The objection is
(

g 13 overruled. However, the witnese, if he feels that he needs l l l
14 his documentation,his own papers, he may so state on the 15 record and not answer the question because he does not have l

l 7 determine at this time that might not be adequate from your f 6 point of view?
\
t g
l A In my preliminary review of the analycis I had , l 1

g , , , - - -
7063 ar8 1 A (Witness Behn) Correct.
2 O What do you mean by inaccessible?
A Where the radiation level is such that personnel 3

and a situation where a -- in the cable spreading room where 7 you have this designated vinyl area and under security a conditions?
g A The likelihood of having a transient material 10 is significantly greater there than in the radiation area.
1 O Is the containment area an area that you have in l 11 12 mind as a nonaccessible area?

0 Mr. Behn, did hhe applicant in its fire ha::ard 0
7 analysis consider any transient combustibles at all in 8 the cable spreading room?
9 'A (Witness Behn) No. j 10 Do you find that realistic?
0 II A No, I don't.
12 O Mr. Bohn, you or Mr. Giardina, one or both 13 of you, indicated that you would be satisfied if the 14 design basis ' fire was applied throughout the Black For c'tation;I 15 is that correct? I 10 A That ic correct.
17 0 Wouldn't it be more accurate to any that you 1E would be satisfied depending upon the outcome of the 19 application of the design basis firo?
20 A (Witness Giardina) Would you repeat that, please?
21 O Is not the mere paper exercise of the planning, 22 the design basis fire, you would have to be satisfied that I

l 7 A I cannot conduct a detailed analysis here. l 1
8 Q Based on the information that you have? )
l 9 A Yes.
10 0 Is it possible, Mr. Dohn, that after a more 11 detailed analysis, and after you have more information 12 that you would be able to identify changes that would not 13 be readily adapted into the Black Fox station, and 14 therefore would be inappropriate for a post-cT consideration?
15 A I believe that all of my concerns can be 10 corrected prior to the operating lice '2e.
17 O At this point, the concerns you have identified 18 at this point?
19 A Yes.
20 0 Is it possible after you receive more information 11 that you will be abic to identify changes that should 22 be addressed before the construction permit is granted?

6 testimony, three lines from the top of the page.
7 A Yes, I see that.
8 It reads, Cable separation guidelines and 0
8 fire retardant cables are not intended to be sufficient 10 alone to protect against exposure fires." '
II A That is correct.

13 on the staff regarding appropriate fire retardant cables?.
14 A I am not sure I understand what you mean.
15 Q How did you determine what cables.have passed 16 IEEE 383?
17 A We relied on the applicant's commitment that 18 the cables will pass IEEE 383.
19 Q Does the staff verify on its own that the 20 . cables so identified and so committed to by the applicant I 21 will in' fact meet IEEE 383?

6 The writer of this document is not before the 7 board. Whatever might be contained in that document --
a because the writer thereof is not before this board and 9 not subject to cross examinetion; nececsarily we have 10 to deny the admissibility of the document.

1 A (Winness Behn) Basically, no. A quart of a 2 flamtable liquid can have the same effect as.300 pounds of ,

3 a certain material. It's the configuration of the room and j r 4 the cable tray arrangement, and wherever the exposure fire is [
(
5 that affects the redundant trains. l 6 Q All right.
7 In the Applicants' fire hazards analysis has it I 1 B been assumed that fire consumes all combustibles in every !
9 fire area there? ,
i 10 A That's correct. l 11 O' In every fire area it's assumed that all 12 combustibles'are completely burned?
13 A That's correct. I must say we have not consideredj
(
14 an exposure fire for all of these areas. l I
15 Q I believe you stated the type of fire - !
l 16 A I believe the Applicant took in h'ic analysic that I,
17 an exposure fire is not critical in a certain area, so he i 16 does not poctulate an ignition source for this area.
19 0 I believe you stated previously when it is assumed 20 that all combustibles totally harned in a particular fire 21 area,'the design basis fire is not important, is that 22 correct?
. 23 A No. The design basis fire is important.
24 1 Q Why?
25 A The design basis fire is an exposure fire which i
i I
7033' !
wel 3 I can'effect total burnup of the fire area.
- 2 , O I'm sorry. I -- ,
i 3 A If you just consider an electrically-initiated fire,'
'( 4 the probability of having an entire burnup in the fire area 1
5 is remote. In an exposure fire it is poscible to completely l j 6 consume the contents of the fire area. f I l 7 O But didn't you previously say that the Applicant l l t 1 0 had considered --
O i A The Applicant had concidered a design basis fire 10 , for a fire area where there were combustible contents on the 4 j
i 11 .: floor. Not transient materials, such as pumps, some kinf'of
.)
12 ) equipment on the floor.
1 13 I'm sorry. I think my question must not be cicar.

14 I thought that you had previoinsly steted that in ;
15 the Applicants' fire hazards analysis that in every fire area j i.
16 I he had assumed a total consumption of all combustibles in the t l
I q : l M i area.
1B A That is correct. l ,
! l 1B Q If everything in the fire area considered is i 20 assumed to be completely burned, then what difference does !
i
21 the design basis fire mahe? .
d t i
F 22]j A' Because in some areas he did not consider an ;

25 ij differenco?
I a
r s v- -

A You still -- just the initiating. source. The 2 combustible contents of the room is still burned.
I 3 MR. SHON: Mr. I',ehn, I think we've run around again l
(- 4 on the same rock as we did earlier, in this examination by 5' Ms. Woodhead.
i 6 If you burn all of the combustible substance in a 7 given area -- and I specifically mean the term combustible 8 substance to include all insulation on all cables in the i
entire fire zone - then what difference does it make what 9 l to the origin of this burning was, as far as its effect on the f i

they caid answer it orally or they wonid need a written 15 motion with legal argument.
16 I indicated then, and I would urge you now, to 17 make a decision on the oral motion, given the assumption 18 that MR. Gallo would have the right to orally argue 19 his viewpoint and also intervenors would be able to 20 argue theirs.
21 We will are arguing also CHAIRMAN WOLFE:
about a third option left to the board on what to do with 23 your-oral motion, so we will reserve ruling between'our

7 8 THe particular part referred to is that design basis firos; 9 this is a section that was read into the record 10 previously. ,
1 11 MR. SHOM: In the first place, that isn't in 1
12 Appendix A to the document; it is in the bottem of the r document itself; is that not correct?
13 14 MS. WOODEEAD: I believe you seu in Appendix A on the first page or taro it says, preliminary definitions 15 16 are referred to in the BTP.
g7 MR. SHON: It is in the bottom of the document gg that these definitions appear.
MS. WOODEEAD: Right.
19 20 MR. SHON: Secondly, perhaps I haven't looked 21 quite enough, although we massaged the section quite.
thoroughly eazlier on; I don't see the words " exposure fire" 22 23 assuchmentionedinthatdefinhon.
MS. WOODEEAD: That's right, Mr. Shon. The 24 explicit words are not there. If you recall Mr. Behn's 25 1
1
l 7098 J
david 5 'l testimony, his interpretation of that for fire protection 2 purposes is an exposure fire; the worst case would be 7
3 an exposure fire.
4 In later revisions of the branch technical 5 position it is explained much more clearly. The word 6 " exposure fire" is used, but this was the original design y basis definition which has been clarified since t
8 then and is readily available to applicants for use. j 9 MR. SHCN: If indeed later Versionc of thic l
to branch technical position make this more clear, why did you l tt not cite these later versions to us in making the motion?
12 MS. WOODEAD: Eecause applicant has accepted 13 this particular branch technical position for its use, v
g and I thought it would be simpler to use his choi;e to 15 refer you to rather than some other Reg Guido or branch l i
16 technical position to avoid the confusion that no have l 17 had about which applies.
MR. SHON: He might voll not have chosen exactly gg {
19 that for just some such reason.as avoiding the term 20 8Kposure fires. -
MS . WOODEAD : I think that would be unlikely, 21 -
22 although I can't testify as to the applicant's mental 23 pr cesses. N l i~

( 4 the fact that your motion makes reference to exposure 5
fires consistant with Appendix A, and then we found 6
that Appendix A references a definition in the body of 7 i the document and that that definition then doesn't use 1
8 ,
the word exposure fires, but you tell us that that is the j 9 i staff's interpretation of the definition. ;

Perhaps your motion should simply have said I 11 "concistent with the staff's interpretation of design l
