3 Without further ado, I turn the meeting
.4 over to Mr. Williams.
5 MR. WILLIAMS: Thank you, 6 it is a pleasure to be here with you.
7 I know you are more interested in 8 technical issues, the status of Davis-Besse, 9 problemmatic issues also related that need 10 resolving if we are to achieve a goal of
- 11. excellence.
12 We intend Davis-Besse to acnieve, by way f) 13~ of background, I spoke to Mr. Williamson, in xs 14 the April time frame, took a look at the 15 operation out here in May, read the various 16 reports from NRC and came to some conclusions 17 of what needed to be done to improve the 18 performance of Davis-Besse and had essential 19 agreement with Mr. Williamson before I decided 20 to finally come out and we agreed that I would 21 come out here but I d idn' t get on the scene 22 until July because I had to close out 23 my other business.
(~') 24 But I d idn ' t come out here specifically
%/
25 because of the June 9th event.

5 l' Let's have the next slide.
[} 2 The organization that I found when I came
-.' w/ .
3 here was not to my liking on what I t ho ug h t was 4 conducive.to good, sound functional operation F.
5, and so I changed it, we are in the process of 6 changing it.
7 This is the way it sets today.
L 8 The dash lines around the boxes means l 9' that is a new position.
L 10' The ones with the slashed sides are the f 11 old ones that existed, but I moved it to a new 12- position.
- - 13- I'm Senior Vice President of Nuclear, 14 Assistant Vice President of Administration 15 Personnel.
16 I have the s e v e r, people reporting to me 17 and I'm' comfortable with that.
18- I found a lot ofLtalent at Davis-Besse 19 when I got here and I d idn' t thirk some of it 20 was properly positioned.
21 So I created the position of the nuclear 22 engineering group directly uner the plant 23 manager, then, administrative 1y to head up the 24 engineering group, also brings to it an r-)
ss 25 operational flavor for nuclear admissions to Ceforotti, Rennillo , adie

1 operate properly.
() 2- Ma terials manag er , one of the problems 3 here was a spare parts support for the 4 maintenance department.
5 The range is not what it should be, the 6 department is not what it should be, and one o f-7 the problems was we did not have in the nuclear 8 admission a n yb'o d y that was responsible for 9- materials, it was solely on corporate support 10 and we b r o ug ht in a very hig hly qualified 11 material manager to do that for us.
12- I want to talk now a little more about f])
( 13 the details of the organization.
14 The nuclear eng inee r ing group director, I 15 brought the operations engineer section of the 16' plant and put it under him.
17 I have established a nuclear plant 18 systems group, I like the engineers to know the 19 design basis of the systems. They know the 20 systems and the operational aspects of it in 21 great detail, make sure that operating 22 procedures do, in fact, reflect the de s ig n of 23 the equipment.
24 They establish the maintenance

1 responsible for the care and feeding of the
' ) -2 systems and components of the plant, the LJ 3 engineering service manager, that includes 4 bringing all our drawings and all our E 5 supporting documentation from Bethel and Dave 6 Berg and relocate on site and they will be '
7 doing line share of all the eng ineer ing .
8 I intend to replace the many consultants 9 with our own people, it will take time, but 10 tha t's the direction we are moving.
11 The nuclear facility engineer and 12 director on this side was here and that was the 13 extent of the eng inee r ing group when I got here, v
^}
14 We pulled the operations e ng i nee r i ng out 15 of the plan, but that d id n ' t mean that we i
16 didn't leave some engineers down there in the .
17 plant.
18 We brought in a new plant engineer, who 19 was the assistant plant manager at Waterford, 20 for operations at the summer station and who 21 had cut his teeth in the business at Point 22 Beach, elevated him, established the position l
23 of assistant plant manager for operations, put r3 24 in operations superintendent and tha t's pretty l 'bj

8 1 to the assistant plant manager.
2 The major organization was not really
- ( J 3 nonexistent, but just not functional, wa sn' t 4 established at the level it should have been 5 established, we couldn't attract the talent, I E 6 established the assistant plant manager of 7 maintenance. I brought in an experienced
[ 8 maintenance manager and he'll talk to you a 9 little later.
10 The new positions we established, you can 11 see what was, I and C superintendent and 12 mechanical superintendent --
/'N 13 The positions that are combined are G
14 yellow flag s. This guy was called a 15 maintenance superintendent and he was down here 16 in the o rg ani za t ion .
17 MR. MICHELSON: Wherever I 18 see a yellow flag, a comparable position did 19 exist?
20 MR. WILLIAMS: Not a 21 comparable one but was purported to do that d 22 function at some level.
23 The green boxes are new positions.
24 Technical support manag er , 12 engineers 25 left in the plant in this group that do the l

9 1 immediate engineering support to the limit of
[')
v 2 their ability and if they can't then they 3 communicate with the group here.
4 MR. MICHELSON: If you never 5 had a technical superintendent until now, how 6 was that handled?
7 MR. WILLIAMS: Well, you 8 have a supervisor down there, you have very few 9 foremen, the foremen primarily did the 10 paperwork, the work gangs were union people led 11 by group leaders who were also union and it was 12 just not, it was just not an organization with 13 support.
(~)'
(
14 MR. MICHELSON: I think I 15 understand.
16 MR. EBERSOLE: You know 17 these organizational charts always blow my mind 18 a little bit. I'm looking for the continuity 19 thread of new functions that will take the 20 place of what was the former, I guess laxity 21 attitude or whatever, that permitted standing 22 deficiencies and design to ex is t until a crisis 23 arose, where can I find that thread or
,e5 24 continuity?

25 MR. WILLIAMS: The thread Ceforotti, Rennillo 3M8"E?s__cogryppenfr L _ dh,

. _ i; 10 1 would be found in the positions that are
'( ) 2 established.
v 3 I b r o ug h t in a very strong plant manager, 4 I can detail his function out in written 5- documents, which they are, the key is to pay 6 enough money and elevate the level of l
7 maintenance, where he could speak witn an 8, authoritative voice, you pay the money to get 9 the r ig ht one and then pay the money to get the 10 r ig ht kind of guys in these positions.
11 MR. EBERSOLE: Would he have, 12 critiquing and having some influence, define
(^
-v) 13 very clearly as deficient, inadequate design?
14 MR. WILLIAMS: If inadequate,
- 15 this gentleman has enoug h clout .
16 On Tuesday, he is sitting r ig ht there 17 along with the plant manag er .
18 MR. EBERSOLE: Had he been 19 here an electric waterpump?
20 MR. WILLIAMS: The guy I 21 have here now would.
22 MR. EBERSOLE: That would 23 hold wa te r .

11 1 MR. EBERSOLE: It didn't
() '
2 hold water way back.
3 -MR. WILLIAMS: I'm not so 4 sure it was said. But I'll assure you that the 5 people that we have in these slots, not the 6 people that I b ro ug h t in, Mr. Quennoz, moved to 7 group engineering, he is not a darn bit bashful 8 about telling me what is required.
9 One thing, he has somebody going to go 10 get it or take some other measures.
11 MR. EBERSOLE: Do you ntend 12 to do an overview or c r :f t i q ue on some other-13 aspects of the plant or just this single
(")i t
14 transient that happened.
15 MR. WILLIAMS: It has 16 nothing to do with this, this is what I would 17 have done.
18 Mr. Willi am so n before-the June Event 19 happened, we 1ooked at the specific different 20 happenings, probably would have been slower in 21 getting into those or im pl em e n t i ng these, 22 certainly that Event created all this, I don't 23 get some as argument about resources I probably r% 24 would have.
U.
25 MR. WYLIE: Is there a plan Ceforotti, Rennillo Ann
& Matthews cour, n.nor,.r. .
,J , ,
12 1 program for analyzing and identifying symptoms 2 which may lead to unsafe conditions in the 3 plant?
4 MR. WILLIAMS: I think what 5 we are doing now in analyzing our status 6 because of the June 9th Event does, in great 7 measure as a starting point precisely what you 8 are talking about.
9 The talented group of people that I set 10 up to look at that and recommend short term and 11 long term actions, covers a multiplicity of 12 system actions.
13 The group that we set up, the analysis 14 work
- hat we have done since the incident
')5 regarding feed and bleed capability and short 16 term, long term, the indepth look that people 17 are taking of the systems that are involved, or 18 of the components that failed during the June 9 19 Event that covers quite a bit of ground.
20 More im po r ta n tly , we recognized, of 21 course, we can get an engineering solution to 22 those and fix those so they would work as 23 de s ig ned to do.
24 It came to the question what about all 25 the other systems that impact on safety.

1 So, we set up groups of engineers to look
) 2. at that and we'll talk about that in detail
_ 3 later to look at those systems and review those 4 systems-to see that their maintenance history s
5 and failure, talking to operators and
. 6 maintenance people, to determine what things 7 need to be done there and.also what testing we 8 had to do to assure onrselves, you uncover a 9 great deal when you start pulling the threads.
10 I hope and intend in the future that 11 those things will be attacked on a day to day 12 basis, the things that we find, we are going
() 13 through all the hangars ag a in , for examnle, in 14 what 7 or 8 of our systems, going back id 15 reviewing our hangars and support syste .
16 I feel confident tht by the time I get 17 ready to start, we'll have a lot of wh4t I 18 think you were talking about publisned as the 19 basis I hope I put in place the o rg an i za t ions 20 of people that were dedicated and inquisitive .
21 e no ug h that you just keep doing this thing as 22 matter'of course or routine.
23 MR. REMICK: Other than the
(^N 24 question on the yellow flag, we have gone
\_.)
25 beyond the clarifications of what is before us.

14 1 I think these are generally questions we 2 can pursue in the question and answer period.
3 Let's proceed, please.
4 MR. WILLIAMS: Another plant 5 manager established the plant superintendent 6 and planning schedule and organization, 7 computer systems manag er .
8 If you are going to run one of these 9 plants and keep on the line as much as possible, 10 you know as well as I do how im po r ta n t good 11 scheduling and planning, the gentleman I 12 brought in to head that organization up was 13 occupied in the same position at American 14 Electric Po we r Plant at Twin Cook Plant and 15 worked for me before so I know what his 16 capabilities are.
17 MR. WARD: Question, does 18 your computer systems manager, does that 19 include the on line computer systems, the 20 process computers or just your data management?
21 MR. WILLIAMS: Data 22 m a n ag em e n t computer.
23 There is a summary of the maj or changes 24 that I made, I have a new plant manager in 25 place, assistant plant manager established, Ceforotti, Rennillo - -
8 Matthews cour,p poner. C.'UllU
7_ -
i
- 15 1 assistant plant manager, maintenance department, 2 key people hired. Materials manager has been 3 established.
t
, 4 We can't have an organization where 5 people don' t know what is expected of them. We C
6 are going to do a writeup and complete position 7 descriptions for all of the positions, some 960, 8 there were 630 when I got here and we expanded 9 the organization to 960.
10 We have a 12 trailer complexes out here 11 to accommodate those and engineering just needs 12 to be where the action is.
'^'
13 The training director now reports 14 directly to me, before this he was reporting to 15 the nuclear service manager.
16 We have a new centralized planning 17 d ep a r tm en t established and nuclear eng ineer i ng 18 has been silbstantially in charge and is being 19 staffed.
20 One of the most im po r t a n t thing s , in 21 increasing the organization from 630 to 960 22 allows me to bring eng inee r ing in-house and 23 beef up the organization.
24 I found that we were not competitive
~

25 salary-wise and I have the agreement of Mr.
Ceforatti, Rennillo -

16 L -
F 1 Williamson to raise the salaries to a
() 2 competitive level and they are being raised on
[-
3 the order of 14 percent across the board, some 4 as h ig h as 25 percent, and some as high as 60 5 percent in January of this year and 40 percent t.
6 in January of next year and yearly merit raises 7 go on as before.
8 I intend to stabilize the organization l 1
9 and go and get the best talent to fill the 10 vacant positions.
11 That is one of the major problemmatic 12 changes.
13: There was no umbrella under which'all the L( )
14 procedures were be i ng written so that you can 15 assure yourself there was no conflict between 16 procedures.
17 We have a maj or operation going on to 18 rewrite the procedures, at the same time 19 without that umbrella we still have to proceed 20 with an i n t e rm ed i a te rewrite of maintenance 21 procedures and operational procedures and later 22 on refurbish and redo them again to fit 23 absolutely under that umbrella.
(Ni x_/
24 The other real major thing is for the 25 con f ig ur a t ion management program, probably 12 Ceforotti, Rennillo d 4 Matthews coun n. pen.n .)
- .. . . . . .. - - _ ~. ._.
17 1 million dollar record, to ascertain what we I'{
v -
2 have in the plant, c om po n en ts , systems so we 3- can write accurate system directions to give 4 the operators the correct design basis for r 5 operating the systems, pr ov id e up to date 6 manuals and accurate base for establishing the 7 spare parts requirements here at the plant.
8 So there are a lot of things going on in 9 parallel.
10 Now, I'd like to introduce to you Mr.
11 Bill O'Connor who will briefly talk about the
-12 operational changes that will come about 13 because of the June 9th Event.

16 MR. MICHELSON: Mr. Chairman, 17 can we ask the questions after each speaker?
18 MR. REMICK: It will be only 19 one hour.
20 How many speakers do you have in your 21 total presentation?
22 MR. WILLIAMS: Five.
23 MR. REMICK: That means 73 24 about ten minutes per speaker.

18 g-1 of' lost after awhile.
vI') 2 The question which_I would like to get 3 to, there are a number of utilities around the
~4 c o u n't r y that have various kinds of experience 5 perhaps alleged by the likes of what you have 6 gone through.
.7 What is your arrangement now to benefit 8 and learn the lessons of all the other 9 ex per ience s , are you doing it yourself, what 10 are you doing?
11 MR. WILLIAMS: We are using 12 INFO and doing it ourselves.
13 Pr im ar ily we are interested in B& W plant
.(G~3 14 and we have a rather large continuity of B& W 15 people here and they are the main source of 16 information for that.
17 Frankly, that is not today my maj or 18 problem.
19 MR. MICHELSON: I just 20 wonder what mechanism you set up to learn your 21 lessons quickly.
22 MR. WILLIAMS: The mechanism 23 is Mr. John Pierson and his group of technical 1
24 people from B& W, the problems with the
(~)g e 1 25 auxiliary feedpumps, in our research we Ceforotti, Rennillo apenhowns w e _
19 l' determined what other plants i.e d similar
()
~
2 problems and what actions they took v
3 MR. MICHELSON: Let me ask 4 it a little differently, maybe you can tell us S- what they are doing.
6 For instance, most of these events are 7 reported as licensee events and go th ro ug h a 8 standard formalization, do you receive each and 9 every one of them for possible applicability?
10 MR. WILLIAMS: Since I got 11 here July 19, I spent much time reviewing, we 12 received those, there is no question about that.
(~T 13 MR. MICHELSON: Most people e v) 14 have always received them, when it comes to the 15 Event, they say, didn't you realize this 16 happened at thus and so, do you.get LERS?
17 They get them but don' t look at them carefully, 18 I'm asking you do you have any organized 19 process by which you are looking at them 20 carefully?
21 MR. WILLIAMS: Today, I can 22 assure you that I have an org ani za tion in place.
23 After I get this June 9th Event behind me rm 24 and get my organization in place and get my
(_)
25 people in place, we will use it.

12 The STA office is within the protective 13 area and the new office is a minute or so from a
14 the control room primarily working out of the 15 shift supervisor's area.
16 Once we have the entire new org an i za t ion ,
17 a shift supervisor, two assistants, and a shift 18 technical advisor, so there will be four once 19 we are fully manned.
20 MR. WARD: Why so many?
21 MR. WILLIAMS: You ca n' t 22 train eno ug h people, the more senior licensees 23 you have around, the more talent it adds to the

4 In the area of em e r g e n c y and abnormal 5 procedures the SRO control room panel area, ,
6 directing actions of the RO once EP 1202.01 is 7 implemented, he is required to be in the 8 control room a t' all times during these Ev en ts ,
9 during June 9th, the assistant shift supervisor 10 left the control room to go down to the 11 s t a r t-up feedpump as we talked about on our ,
12 tour, the shift supervisor had momentarily gone
/~ N.
(,,) 13 to the office to get-extra keyrings to have 14 with them-to get to various locked valves, for 15 a minute or so there was no SRO in the actual 16 panel area that we discussed.
17 We are making that a requirement.
18 Once we enter EP 1202.01, the SRO must 19 remain in the control room panel area directing 20 actions of the RO once EP 1202.01 is 21 implemented.

10 You cannot ask a man to do something at 11 600 degrees if the meter is not calibrated.
12 We are walking through every emergency i 13 procedure to insure that every time we tell 14 them at such and such a point do this, 15 that the meter will support that decision.
16 We are providing manual pressure 17 temperature plotting capability on the operator 18 console and if it is not functioning that the 19 operator can manually block that temperature 20 and for the longer term events this is vital, 21 the short term events it is not necessary.
22 It is im po r t a n t to know where the plant 23 has been and where it is going.

() 2 In the new procedure with the analysis 3 that B&W and engineering performed for us we 4 have found that we can give them a single 5 criteria of-600 degrees on the safety grade hot 6 leg temperature accelerates which is very easy 7 to observe in the control room.
8 We are going to correct the SFRCS 9 response verification. It changes 10 significantly, tabs corrected in the pr oced ure .
11- - There was a few minor errors in this tab 12 on the n ig ht of the June 9th Event but it did
(~ 13 not cause any problems for the operators, but s
14 there was a few minor errors, the r e a l ig nm e n t 15 of the auxiliary feedwater mini-recirculation 16 flowpath.
17 It will be realig ned within a f ew minutes 18 after the auxiliary feedwater pump starts to 19 allow minimum recirculation flowpath.
-20 The MSIV, both close within several 21 seconds of the reactor trip.
22 When the operator was going through his 23 supplementary action and when it was determined r%- 24 that the main steam isolation valve was closed U
25 and verified a little earlier in the procedure, Cefaratti, Rennillo q

( ,, ,.,
27 1 moving up to one of the initial supplementaries,
( ) 2 immediate action was taken to verify MSIV, new 3 motors driven feedwater pump operation 4 obviously has to go in in the procedure, the 5 new pump operation is different than the old 6 one, this pump explicitly is outlined and its 7 operation is put into the emergency procedure.
8 The criteria for AFW suction transfer 9 from the service water to the CST, condensate 10 storage tank.
11 If this transfer occurs, we need specific 12 criteria when it is appropriate to transfer 13 back to the condensate.
w.j' 14 Under the training and adm ini s t r a t ive ,
15 the first item, increased emphasis by 16 management and training on adherence to 17 procedures.
18 We do not feel we had significant 19 problems on the operators to adhering to 20 procedure, we are just reenforcing when the 21 emergency procedures are developed by the 22 operations department and technical e'ng i n e e r i ng 23 d ep a r tm e n t , we are sitting in a room and 24 thinking of all the what ifs and when it is 25 appropriate to do this particular action, why a Ceforotti, Rennillo

28 1 certain time frame mig ht be im po r t a n t , why 600
) 2 or 12 hundred or 2 hundred pounds is important, 3 the operators should not be interpreting these 4 items in the control room d ur ing the Event.
5 Once this criteria is established, they 6 have to follow that procedure to the letter of 7 the law especially the emergency procedures.
8 Next is pre-startup training of all the 9 operators on hig h priority infrequent operator 10 actions, (e.g. AFWT trip throttle v alv e) .
11 The operator that was performing that 12 function never operated it in that particular
! j 13 mode.
14 One thing we are doing for all the 15 operators on this specific item is we are 16 requiring that every operator actually start 17 that auxiliary feedwater pump with live steam 18 pressure.
19 Another item that has come out of the 20 i nv e s t ig a t i o n is the em e rg e nc y diesel generator, 21 it has a limit switch and the limit switch can 22 be reset if the arm is pulled down properly.
23 We have a tag there that has been there
( ') 24 for years, however, we want to insure the 25 operators are all aware.

29 1 There are several others that we have i
/")
q 2 uncovered in our investigation.
3 Manual versus automatic safety system 4 actuation.
5 Operating philosophy changes requiring 6 the reactor operator to inform the senior 7 reactor operator of intent to manually actuate 8 the system.
9 He will be required to tell the senior 10 reactor operator, I'm going to the. operator on 11 low level prior to taking that action. -
12 In other words, the SRO must concur with j
,( 13 the action.
14 There are t im e s where it is required to I 15 manually where you cannot sit back and let it 16 do it automatically, situations such as loss of 17 instrument air in the plant.
18 It can be actuated prior to losing air, 19 this is one ex am p le where the operator is 20 required to take a manual before letting 21 automatic do it. !
22 MR. EBERSOLE: Is the 23 inversion of that also going to be examined?
24 You will repeat if you see it was leading you 25 down the wrong path?
Cefaratti, Rennillo d"
& Matthews court Reporters
30 1 MR. O'CONNOR: The operators
() 2 based on the particular events going on, always 3 have their operational judgment, if a safety
( 4 system is not doing what it is supposed to, j l
5 don' t stand there --
6 MR. EBERSOLE: Have you 7 examined bypasses at all? l l
8 MR. DEAGAZIO: Currently in 9 place are all the areas that we know we will 10 have to do as part of our review of the 11 emergency procedures, we have uncovered a 12 couple other places, depending on the changes
,s (w,) 13 to the steam feedwater rupture control system, j 14 but, yes, we are looking at that specifically.
15 In the June 9th Ev e n t , the operator knew 16 that he lost steam by the main steam isolation 17 valves going shut.
18 What was going through his mind on the 19 n ig h t of June 9th was that I had a SFRCS 20 actuation and the system did not respond the 21 way it was supposed to, it partially did, the 22 main steam isolation valves and nothing else 23 happened.
(~') 24 In his mind the steam feedwater rupture v
25 control system was not functioning properly and Cefaratti, Rennillo

31 1 he was putting it in the condition it was
' _) 2 supposed to be put.
3 In other words, in his mind the feedwater 4 was gone, the SRO had actuated and the main 5 steam isolations were shut.
6 MR. WARD: So, he wa s n' t 7 really anticipating an automatic action?
8 MR. O'CONNOR: They knew he 9 had lost feedwater, they didn't understand why 10 the SRO had shut it down or closed it. He was 11 attempting to put the system in line up.
12 He was doing what he felt was correct l ,I 13 based on the condition in the control room.
w./
It 14 wa s n' t that he was anticipating boiling, he had 15 a safety system actuation that was not correct.
16 MR. QUENNOZ: I think the 17 answer to that question, Mr. Ward, would be a 18 manual versus operator initiated action.
19 Bill is trying to describe too many 20 situations to legislate such a pat answer to 21 that.

5 MR. WARD: Maybe that is so, 6 but you are. putting a big load on the senior 7 reactor operator.
8 MR. O'CONNOR: They always 9 have a big load, he is the shift supervisor.
10 MR. WARD: I m ig ht suggest 11 that the engineers a nal y ze in the quiet of 12~ their offices and laboratories through the
()
13 years can think out more of those things than 14- you mig ht expect the SRO to think of.
15 MR. EBERSOLE: In that 16 connection, it is my understanding that the 17 operator.second to the organization in general 18 are more or less committed to operate what they 19 are g iv en and have very little credit in trying 20 the des ig n itself, they must run it, it is a 21 privilege to run something as difficult to run.

22 They got used to the SRO trip alarm and 23 looked at the actual buttons in the back, did

9 Are all of your operating procedures now 10 based on --
11 MR. O'CONNOR: Our em erg enc y 12 operating procedures are the sy s t em s based

17 MR. DEAGAZIO: Yes.
18 MR. MICHELSON: You said 19 something about loss of air and you would like 20 to get things to happen before you lost the air.
21 Isn't your design fail safe on loss of 22 air?
23 MR. O'CONNOR: The design
(^'; 24 for the safety system is fail safe on loss of t/
25 air but can g iv e you overfilling.

'4 MR. O'CONNOR: We have an 5 automatic closer to the containment which stops 6 the main feedwater valve.
7 No, they wo n' t overfill.
8 MR. MICHELSON: Don't you 9 have to respond to lose of instrument air?

17 Now, one final question, on your 18 simulator you were having to use the then B& W 19 simulator present.
20 MR. DEAGAZIO: Yes.
21 MR. MICHELSON: Is n' t there 22 a sister B& W plant that looks a little more 23 than B& W simulator which really is not all that rS 24 good, isn' t there a better place to put your

22 I'll discuss briefly the cha1ges that 23 have been im pl em e n t ed as part of the I
/ 24 maintenance im p r o v em e n t program, the changes 25 that occurred in organization and staffing, Ceforotti, Rennillo ^-

) 2 procedures, preventative maintenance, spare 3 parts and material control, eng in ee r ing 4 interface and support, plant cleanliness and 5 material readiness, facilities.
6 The new maintenance organization has been 7 in place since the 19 of August, the 8 crganization chart was f o rm a ll y approved in 9 September.
10 All the positions that you see as second 11 level supervisory positions from the lead 12 . engineer, general foreman, superintendent up,
() 13 have been filled since the 19 of Aug ust .
\ /~
14 Some of the former slots are still being 15 filled by t em po r a r y upgrading of craft 16 personnel.
17 We are in the process r ig ht now of 18 pe rm a ne n tl y selecting and placing the 19 individuals into those positions.
20 The intent here is several fold.
21 The maintenance org an i za t ion consists of 22 epproximately 209 people, 40 some of those 25 people were not directly involved with
, m. 24 maintenance activities but are per f o rm ing f j 25 support activities such as system engineering Ceforatti, Rennillo - ' -
W . . ??' .""*"" NN
42 1 and planning and sc hed uling .
f) 2 The c ur rent maintenance orgsnization is p
3 199 people, ex clud ing myself, all those people 4 are directly involved in maintenance activities.
5 One of the reasons for two levels of 6 supervision within the organization and these 7 two levels,- the ones I'm talking about, is to 8 allow the superintendents and the general 9 foremen to become-part of the industrial f o r um 10 such as INFO, ASME and others and to play a 11 better role in the industry and see what the 12 industry is doing.
f"]
(s 13 The INFO has a very good program and were 14 here this week and we discussed this and we are 15 working out the schedule for som e of that 16 activity ourselves.
17 Additionally, I have increased the number 18 of foremen in the organization.
19 To give you an example in the INC yard 20 the old ratio of supervision to craft was 21 1 to 23, currently it is 1 to 7.
22 In the mechanical it was 1 to 21, 23 currently it is 1 to 10.
(* 24 Electrical, it was 1 to 23, now it is (s
25 1 to 6.
Cefaratti, Rennillo '-
l 8 Matthews coun R.ponm ( ((] __
43 1 There are several reasons for that, one 2 of them is improved supervision in the-field, (v!.
3 very seldom do the foremen ever get to leave 4 the shop to go observe maintenance in the field 5 but are tied down with paperwork and routine 6 personnel matters.
7 I require r ig ht now each foreman spend at 8 least 75 percent of the workday in the field, 9 one hour of that workday is dedicated to 10 inspections for cleaniness and material 11 readiness and areas I assigned to them.
12 In addition to that, each of the
() 13 maintenance personnel especially the general 14 foreman.and superintendent are required to 15 spend a minimum of one hour a day in the plant 16 and inspection check list that they fill out, 17 they have assigned areas and the areas are 18 rotated on a monthly basis.
19 We have currently built up some 14 to 15 20 hundred work items as a part of this material 21 readiness and inspection program they are 22 primary tied and funneled back into the 23 schedule for~ work off.
[ 24 I have about 40 mixed craft and clean 25 personnel that are a dedicated work force under Cefaratti, Rennillo > - -

3 an ongoing cleaning activity to im pr ov e the 4 status of p l a n't cleanliness and material 5 readiness.
6 Once he left that area, that area is 7 evolved into an ongoing cleaning schedule.
8 Communications appear to be a problem in the 9 organization so I established schedule meeting 10 t im e s with our personnel, 11 I meet daily with the superintendents, 12 engineers and general foremen.
1 13 I meet with them at 7:30 in the morning, w/
14 once a week I meet with the foremen, once a 15 week I meet with the union stewards.
16 I meet monthly with each discipline and 17 quarterly with the d e p a r tm e n t as a whole, and, 18 of course, we discuss the plant administration 19 ongoing a c t iv i t i es .
20 To give you som e idea of the experience 21 level in the organization, from this level up, 22 there is 155 years of nuclear plant experience 23 anc within the 155 years experience, 60 years

5 MR. WOOD: I am mechanical, 6 structural engineering manager and I am going 7 to speak today about the equipment and 8 specifically that which ruptured as a result of 9 the June 9th sequence of events.
10 I'll go very rapidly through these so we 11 can save some time for the last two speakers.
12 The first slide here represents a flow I')_
13 chart of basic process.
14 The first item I have is main f eed pum p 15 turbine.
16 What we found in our review process was 17 we had a failed circuit board capacitor in our 18 GE control system, this is a MD 20 system that 19 we installed just r ec e n tl y .
20 This capacitor was in a frequency to 21 voltage, which then told the. control system 22 that I have no speed, therefore, increase the 23 speed and I ended up tripping out on overspeed.

3- 6-9 and these-are the only control systems of 4 that type in the plant.
5 Next concern, steam feedwater rupture 6 control-system, spuriously had an actuation 7 closed both main steam isolation valves and 8 isolated the steam to the main feedpump and cut
.9 off the primary force.
10 We found in our investigation that this 11 actuation was due to the pressure oscillating 12 which the SRO incorrectly-interprete'd as low rm '13 level and, the turbine trip causes that valve
'(_)
14 to close, causes a pressure oscillating back 15 into the secondary side, that oscillating, of
.16 course,1would have been with us from day one of 17 the' operating plant, however, again in the 84 18 releasing outage, we made a change to the level 19 pressure, we had some Ro s em o n t transmitters
~20 that we changed, the Rosemont moved less fl u i d b 21 in their actuation, therefore, the level became 22 more sensitive because the old transmitter 23 provided a snubbing action and the new 24 transmitters did not.

-3 MR. WOOD: No, the first 4 time we had a full SRO trip as a result of the, 5 we had two indications early of a half SRO trip.
6 MR. MICHELSON: A previous
- 7. indication when you trip is you are getting 8 noise?
9 MR. WOOD: Th a t ' s true.
10 Auxiliary feedpump turbine tripped on overspeed 11 after the Event. '
12 It was a backup to the ' pr im a r y' so ur ce .
13 Here is what we have f o.u nd in our i nv e s t ig a t i o n
{}
14 at Davis-Besse and also reviewing information i
15 from other plants and discussions with turbine 16 manufacturing that the cause here is 17 condensation which forms long cool steam inlet 18 lines, normally set at ambient temperature and 19 actuate the system b ro ug h t up to a 500, 600 f
20 degree temperature. This condensation can 21 disrupt the turbine control.
22 In other words, to correct what we are 23 doing, keeping the line hot pressure raised 24 with steam, of course, reduced the water 25 formation also allows our steam traps to work i

- We are putting r: 5 the steam emission valves into the auxiliary 6 feedpumps.and thus instead of having to

'8 other side as-long as'650, if you include the l:

8 At the end of 1984 what this d id was 9 allow both paths of steam to feed that 10 particular auxiliary feedwater pump and enhance 11 the probability that the pump would get a 12 source of more force.
fv-') 13 We found after we made that modification 14 that we were, we saw hangar danger, when we 15 identified that, we put the, logging .back to its 16 o r ig i nal form.
17 We had worked with the reg ion under 18 affirmatory action letter to further 19 inv es t ig a te the hangar danger that we found and 20 be sure-we found the root cause of the problem

!i 10 similar, maybe, events. Nothing that 11 duplicated what we saw, ag a in , it was ,the first

12 time we had oversped a turbine '
13 One of the.more significant things that (m)

65 1 certain ones of these additional ones they 2 would particularly like to hear about, your 3 slides.
4 MR. WOOD: Maybe if I can 5 just conclude with this one, I think this is an 6 im po r ta n t finding not only by Davis-Besse but 7 for the industry.
8 MR. REMICK: I ask the 9 subcommittee to look ahead.
10 MR. WOOD: This has to do 11 with the auxiliary f eed wa ter valves 599 and 608, 12 which failed to open on d em'a n d after closing 13 early. The operator pushed the wrong two push 14 buttons, howev er , after he. corrected his 15 mistake, a minute or so later it should h av e 16 come up automatically.
17 What we found the motor operators set, "
18 corked out prior to opening, when the operator 19 went down there and gave a hand assist using 20 the hand wheel, it then br o ug h t it open. The 21 findings again are that the l im i t switches and 22 the torque switches were not set up exactly 23 correct for motor operator valves, the l im i t 24 switch puts the torque switch into the circuit 25 on a selected opening of the valve.

66 1 our previous point where the limit switch r

i 5 What-we have found, if we had used the 6 procedure which we had s ome help ~by another 7 consultant in developing there was not en o ug h 8 margin there that the torque still existed when 9 the torque switch was put in and, therefore,

15 MR. LINGENFELTER: We are 16 not going to have a restriction like that.
17 MR. MICHELS0'N: One more 18 question.
19 You have probably gone th r o ug h an 20 exercise in which you describe to the NRC what 21 you were doing in the unlikely event of loss of 22 all AC power, can you tell us b r i e fl y , is that 23 expected to play an im po r t a n t role?

12 MR. JAIN: I am Sushil Jain,

- 13 senior nuclear engineer.
14 I'll be talking about a very complicated 15 and important activity.
16 After the June 9 th , 85 event most of the 17 systems that were involved in the June 9th 18 Event pertained to the removal of the heat, 19 namely the maintainence heat and, the start-up 20 feedpump, the SRO which is the initiating roll 21 system for the oscillating feedwater and 22 primary side.
23 The task force identified changes to
-. 24 prove the operation of the reliability as well 25 as the problems and complexity.

70 1 The task force enj oyed a very broad rn- . .
!. ) 2 membership consisting of several senior level 3 people as well as people with experience in 4 e ng i ne e r i ng as well as operations and licensing.
5 The overall goal in achieving or arriving 6 at these recommendations was to insure the 7 system reliability.
8 The methodology was deterministic as well 9 as preliminary scoping analysis.
10 Several alternatives or recommendations 11 for evaluation showed that they would work, to 12 make sure it does come on, and, finally, when
/^
(' s) 13 it does come on, you'make sure it continNes to 14 run.
15 To enhance eng in ee r ing efforts on the SRO 16 the manual actuation' buttons will be rearranged 17 and closer plates be provided to minimize any 18 situation 19 MR. EBERSOLE: Because of 20 the ex tr eme importance, I wonder if you can put 21 together your feelings about the availability 22 or lack of automatic suction pressure trip on 23 these critical feedpumps.
f')
v 24 MR. JAIN: We have a low, 25 low, suction pressure of the oscillating Ceforotti, Rennillo d R Manhmn wacermrm_. . .
71 1 feedpump turbines.
2 The task force has looked at possible 3 e l im i n a t i o n of that trip.
4 In the short term we are planning to add 5 a time delay so it does not cause the trip of 6 the turbine and the longer term because of the 7 technical specification we are proposing a 8 deletion.
9 MR. MICHELSON: Is it your 10 intent in improving the equipment or feed and 11 bleed to provide eno ug h relief capacity so that 12 the h ig h pressure inj ection pumps will be the 13 feed source or do you plan to sti11 rely on the 14 charging pumps?
15 MR. JAIN: The intent here 16 is to come out with the capability, there are 17 two ways you can look at it, one way is to 18 provide enough relief capabilities wherein you 19 can use your existing pumps. The other one is 20 to put in a single failure proof, inj ection 21 capability. The most attractive option here 22 appears to be more increasing the releasing 23 capability of the HPI system which minimizes 24 and impacts on the i nj ection capability. So
.)
25 that's what we are pr e s en tl y looking at.
Ceforotti, Rennillo
& Matthews cour, Reporteri p
d,
72 1 MR. MICHELSON: Increases 2 the releasing capability so you can use the HPI 3 system?
4 MR. JAIN: Correct.
5 MR. MICHELSON: Could I ask 6 you a question about the revision, SRO panel, 7 the term that is used there for actuating that 8 system is trip, and to most people, trip is 9 also used when you trip a turbine, it means it 10 goes down.
11 When you trip the reactor, that means it 12 is shut down.
13 I wonder in your human factors, control 14 and design review, the human factor specialist 15 objected to the use of the word trip as you use 16 it there?
17 MR. JAIN: The control room 18 design had not identified that as a deficiency, 19 most of us here that utilize the SRO trip --
20 MR. MICHELSON: I realize 21 that if ev er ybod y ag r eed you would get by, but 22 it wouldn't be c omm u n i c a t i ng very well, good 23 old words like open and close, start and stop
( ) 24 are better than, I think, than the words like, 25 isolate and secure and trip.

73 1 MR. LINGENFELTER: I was i mj 2 involved-in control-room design and that 3 particular item was discussed a number of times 4 with our human factors people.
5 The common terminology is the best thing 6 and the operators are very c om f o r ta ble with 7 that.
8 Unless there is a specific change in 9 their terminology we are going to try and 10 continue with the use of the type of words the 11 operator is used to seeing. -
12- MR. MICHELSON: How do you t
(b). 13 open the steam line to the big water turbine?
14 MR. JAIN: This is one of 15 the slides I think in the back of the handout..
16 The motor operator valve here and here would be 17 open and these are operator valves, the steam 18 emission valves are operator valves DC 19 solenoids.
20 MR. JAIN: Right, we are 21 adding a new valve to replace the function of 22- the MS106.
23 This one is air operator.

2 MR. MICHELSON: You are 3 adding a valve and have an air operator instead 4 of a motor operator.
5 MR. JAIN: The loss of air 6 to the valve will fail open.
7 MR. MICHELSON: I understand 8 now what you are doing, I d idn' t quite 9 understand your statement.
10 I'm sure you understand by moving, you 11 know there is a problem here, one way to solve 12 your problem of heating all the lines is to put
~

14 Instead you have chosen to pressurize in 15 an area containing many components, you 16 undoubtedly increase the risk, you have 17 increased the risk significantly I think, 18 although it still may be a low risk.
19 Now why did you think it was better to 20 fill out the lines with steam instead of 21 putting in a bypass valve?
22 MR. WILLIAMS: We are still 23 analyzing that, we are still looking at

6 MR. MICHELSON: You said you 7 had a strainer in the auxiliary feedwater 8 straining, what type of condensate storage tank, 9 why do you use a strainer, is it that dirty?
10 MR. QUENNOZ: In a 11 n o n- s e i sm i c b u ild i ng in the event you would 12 have a seismic occurrence the or ig in al put 13 strainers in the auxiliary feedwater, to 14 prevent debris.
15 MR. MICHELSON: Interesting 16 concept as it pertains to a lot of lines, 17 upstream and downstream, if you are shaking 18 rust, it will be up and downstream as well.
19 MR. QUENNOZ: Downstream, it 20 is actually inside the auxiliary feedpump.
21 MR. MICHELSON: But still 22 rust.

4 MR. STOLZ: Good afternoon, 5 my name is John Stolz and we have the members 6 of the staff from NRC from the region to assist 7 the committee in answering some questions they 8 may have regarding status of our r ev i e w .
l 9 This afternoon, basically we want to 10 cover two things, the status of the ongoing 11 review, which has not been going on very long 12 and also the status of generic issues that f" ) 13 arrived primarily from the June 9th Ev en t and v
14 other things that the staff thought about.
15 First, let me g iv e a little history of 16 how we got here.
t 17 Following the June 9th Ev en t , the region 18 issued a confirmatory action letter on June 10, 19 subsequent to that, NUREG 1154 was issued by 20 the fact finding team and we issued A 5 0.54 ( f) 21 to the licensee principally derived from the 22 1154, plus additional items that the staff 23 thoug ht about.

1 the status of the staff review in accordancea (sh _. 2 with essentially the 5 0. 54 ( f) that we sent out.
3 Subsequent to that, Dick Wessman will be 4 talking about the generic. issues under 5 evaluation and,-let me give you a r o ug h idea of 6 where we are on the schedule, we expect to get 7 the first input from the staffs review in about 8 two weeks.
9 We are running in parallel with the 10 licensee on a few issues.
11 We think possibly the pacing issuing is i
- 12. the testing program, the licensee is in contact 1 t'.
i- 13 with the staff, the staff and reg ula r phone, 14 r eg i on staff and our staff form a team, they 15 plan to join with the licensee in coming up -
16 with r ev ie ws in the licensee's test program.
17 We think that's the pace of the issue in terms
~18 of time.
'19 I would guess that it will be probably 20 toward the end of November before the staff
.21 will be ready to issue a safety evaluation that 22 would have to go through manag ement review and-23' then be subsequently issued.

2 the issues of the SER, we have to ag ain mee t 3 with you folks, I'm speculating on that.
4 MR. EBERSOLE: The fourth 5 bar under that first bulletin, conducted that 6 underlying cause of events, et cetera, was lack 7 of care and maintenance, do you really believe 8 that?
9 MR. STOLZ: I think if you 10 use the word maintenance, that certainly was 11 maintenance but also included some of the 12 engineering that went back of it.
'(, 13 MR. EBERSOLE: You don' t say 14 that, don't say anything about the lack of 15 d iv e r s i ty or anything else like that. I r eg ard 16 that as a protective statement in the context 17 of saying the reg ula t ion will give you a design.
18 MR. MICHELSON: The-real 19 problem is lack of understanding on some of the ,
20 equipment, both on the part of the staff and 21 industry.
22 MR. WARD: That is something 23 different from what Jesse is saying.

l 90 1 The concerns that Toledo Ed i so n is
) 2 addressing, has addressed and is continuing to 3 address in their work and in their supplemental 4 course of action report was in response to the 5 letter that had been issued. That the concerns 6 that were listed in that letter were drawn 7 largely from the find ing s of the inv es t ig a tion 8 being sent down to the site just shortly after 9 the June 9th event.
10 The concerns in that letter can be 11 broadly categorized as first, follow up on the 12 i nv e s t ig a t i o ns of the Event.
) 13 Secondly, look at the specific 14 circumstances surrounding the Event and thirdly, 15 examine the problemmatic management issues 16 surrounding the way in which the plant was 17 p er f o rm ing .
18 With regard to the first category, the 19 completion of the Event investigation, Toledo 20 Ed i so n has identified, I think the 13 root 21 cause reports related to the equipment failures 22 that occurred during the Ev en t , we have 23 completed out r ev iew of six of those 13, four

6- In the interest of saving time the 7 findings I believe have been provided to you 8 but we d idn' t have the opportunity ~to present

9 MR. WARD: What specifically l l
10 about the feedwater systems prior to June did i 11 not meet licensing requirerents?
12 MR. PARR: We thought they (L;) 13 met the criteria, they do not.
14 MR. EBERSOLE: Why not?
15 MR. PARR: Because of the f 16 problem in the switchover system, that would
} 17 not meet requirements.
18 MR. MICHELSON: The f
19 enviromental pr otec tion relative to the turbine i
20 building, steam release, as a matter of fact 21 both departments, unless you can show both 22 departments are qualified for that release, it 23 is not clear.
24 MR. WARD: Is there any
( })
25 other plan in the country that will meet that Ceforotti, Rennillo

93 1 sort of criteria?
j 2 Feed water analysis, how much margin is 3 there, there is available as far as time and 4 what other equipment is available in order to 5 adequately, all main feedwater and auxiliary 6 feedwater, the licensee has pr ov id ad some 7 counselors evaluated by the staff the staff has 8 done its own analysis of the ability of HPI, I 9 think, and makeup p um p s and PORV cooling the 10 time margin that is available before cooling 11 and recovery.
12 With respect to its operation, it may or
(') 13 may not exist in the steam water control system.
14 There is a single failure problem or not, I'm 15 not sure that the staff has made a final 16 determination as to whether or not there is a 17 single failure problem, that is still under 18 inv es tig a tion as far as I know.
19 With respect to physical security and 20 administrative features, I don't think I need 21 to say anything on that.

3 MR. WESSMAN: Let me 4 respond, that is one of the identif'ied short I 5 term generic issues that ensued from this Ev en t .
6 The staff will go back and look at it, the 7 security on an eng inee r ing basis for all plants, 8 to see whether we have a problem here. I'll be 9 talking more on the several types of issues 10 when I get my turn, 11 MR. DEAGAZIO: Jumping down 12 to number 7, the reliability of AFW system j 13 pumps and need to d iv er se pumps.

14 We are looking to make independent 15 ev alua t i on of this and evaluating the design 16 Toledo Edison is prov id ing for the new style of 17 feedwater pump.

19 13 the adequacy of safety system testing.
20 You heard Toledo Ed i s o n discuss what they 21 are d o i ng with respect to the systems review 22 and test procedures. The NRC is, has a joint 23 effort between Region III and NRC, we also have (3 24 one individual I believe from INE who will be

2 MR. EBERSOLE: I'd like to
' ((h 'i -
N-s/ : 3 comment on. Item 8 and ask you a question, 4
4 t h a t s certainly a generic item, wherever we 5 have non-CEP w i. t h SRO, in that system has never ,
6 been e nv i r o nm e n t a l equal tied to meet the
, 7 conditions it can create to itself if you hold i .
8 it open.
9 MR. WESSMAN: Yes,
, 10 MR. EBERSOLE: Did you 11 contemplate a subject as to whether that o ug h.t 12 to be fixed?
I i' 13 MR. WESSMAN: Longstanding i.
14 ever since we found we might lose feedwater and 15 have to invoke,.we have all known for a long 16 time, if we prolong feeds we -presumably disable 17 the solenoid hot electric operation, shut and 18 stay shut and therefore lock up the plant
- 19' ag a ins t any further immediate, are you going to
, 20 have an extended investigation as to whether we h 21 can permanent the continued ex is tence ,: in the 1
22 wholesale.
l 23 MR. WESSMAN: The issue is 24 under consideration pursuant to generic issue
(.
25 70, .I believe, I don't know the. full scope of Ceforotti, Rennillo yd A AAe n.aws @vre Rewriers
96 1 generic 70, it deals with both PORV and the 2 block panel and repeat, as a result of this 3 Ev en t that same item basically got put on the 4 list to be sure we are looking at it, PORV.
5 The enviromental qualification of the valve, 6 water e nv i r o nm e n t or temperature environment, I 7 don't know the scope of that level.
8 MR. MICHELSON: I need a 9 clarification, maybe the utility will have to 10 provide it. As I recollect, when I looked at 11 auxiliary feedwater turbines and pumps, one was 12 inside a concrete structure with a heavy door, 13 et cetera, the other one along with the 14 electrical pump was in another structure which 15 I tho ug ht had a grated ce il i ng , was that my 16 correct recollection.
17 It is grated and opens into the turbine 18 building essentially.
19 MR. MICHELSON: I t ho ug ht 20 one had a ceiling was sealed up with a blowout 21 panel, three by three feet I was told, open 22 grating on both.

7 Is there eno ug h strength in that ceiling 8- to take care of all that stuff up above, 9 wbntever mig h t be released?
10 MR. MYERS: That was issued

(~)T 14 common intrusion of both feedwater rooms?
15 MR. MYERS: Also, yes.
16 MR. MICHELSON: Also has the 17 problem of water breaks and water lines.
18 MR. MICHELSON: It's an 19 unusual arrangement to put a safety related 20 system in a nonsafety building like this.
21 It can be done but it requires great care.

6 MR. DEAGAZIO: The only 7 comment I want to make with respect to this 8 sl id e , parallel with the first item on the 9 slide, we also just last week completed a 10 review of the progress, 11 Reg a rd ing accreditation, we don' t have 12 the results of that review yet.

15 MR. REMICK: I'm not sure I 16 understand.
17 If you know they are accredited, how can 18 that factor in?
19 In other words, they aren't required to 20 be accredited, you know they are not, how can j 21 that been factored into restart, I don't 22 understand. ,

8 Two weeks ag o we had a team out here
- 9. wh i r:b examined the maintenance program, 10 p r e l im in a r y find ing s -f r om this survey have come 11- to.the not surprising conclusion that past 12 practices were less than desireable or could

16 started and there ha sn' t :been an adequate 17 amount of experience with.that to make a 18' statement-of how effective they are.
19 Our report from this team should be
-20 available appr o x im a te ly the end of this month, 21 so the appropriate parts on that will also b e'
.22 factored into the restart safety evaluation.

100 1 observation I made in the tour, hearing about i ) 2 the maintenance problems which apparently 3 Davis-Besse had, I was somewhat surprised to 4 find what I t h o ug h t generally good material 5 condition of the plant, I guess this is my 6 first trip here, I would guess I would have 7 seen something not quite of the quality,
. 8 material quality that I did see, this is an 9 observation of the staff also.
10 MR. DEAGAZIO: I think the 11 ni a i n t e n a nc e , the issue of maintenance may get 12_ back into areas which may not be tho ug ht of as 4-() 13 maintenance.
14 For example, a follow th r o ug h on a 15- malfunction, the investigating team may make 16 the conclusion that in many cases when there 17 has been a f ailure many of the follow up 18 inv es tig a tions may have been superficial.
19 I think the plant's general condition is 20 better, much better now than it would have been 21 had you seen it a couple years ago, this is a 22 year, you know from our reports that we have 23 continuously been involved and general
(^'i 24 maintenance and housekeeping has been a matter

3 MR. REMICK: When I see 4 things that are clean and orderly, it usually 5 means good management and maintenance.
6 MR. MICHELSON: Are you 7 going to insist upon a safety grate isolator on 8- the hydraulic and electrical, et cetera?
9' MR. ROSA: That's our intent, 10 yes, sir.
11 MR. WARD: Al, in looking at 12 the readiness for restart, has the staff
() 13 considered the rather ex tensiv e organization 14 changes that the licensee made?
15 MR. DEAGAZIO: There will be 16 a evaluation of the new organization that will 17 be in place, yes.
18 MR. WARD: Do you think 19 those changes are in the favorable direction?
20 MR. DEAGAZIO: We hav en' t 21 completed the evaluation in that respect. I 22 said that will be evaluated.
23 MR. REMICK: What criteria 24 are you going to use for making such an
(~}
v 25 evaluation?
CefaraMi, Rennilla d
& MoMhems eoert Reporrm a
102 1 MR. DEAGAZIO: That I
/ 2 couldn't tell you.
3 MR. MICHELSON: Let me ask 4 you, you said SER was not being issued until 5 late in November, it was kind of my impression 6 that the licensee intended to restart about 7 November 1, does this now mean restart much l 8 later than that?
9 MR. DEAGAZIO: My 10 u nd e r s t a nd i ng is there is no definite target 1
11 established now for restart.
12 MR. MICHELSON: Obviously
() 13 considerably later than November l?
14 MR. DEAGAZIO: Yes.
15 MR. REMICK: Does the 16 licensee have any response?
17 MR. WILLIAMS: I don't know 18 what you mean by that much later.
19 I wanted to go to start-up on November, 20 start progress the first week of November, but 21 I can't do that.
22 liR . MICHELSON: The thing I 23 would like to see in the safety evaluation is
) 24 the question you have been raising concerning 25 the h ig h energy line breaks in such Ceforotti, Rennillo '-
a unnhow< c ~ ,, e . ...,, ED0 0 l
103 1 ! c om p a r tm e n t s and the ability of valves to
.() 2 isolate and assure isolation of the breaks or
~
3 alternatively that you will account for the l 4 lack of isolation.
5 I would be looking for that as part of 6 the evaluation of the new a r r a ng em e n t since it 7 is at a considerably hig he r risk level. l l
8 MR. WESSMAN: My name Dick 9 Wessman. I'm from the div ision of licensing in 10 NRC.
l -- 11 I want to give you a brief synopsis of 12 where the staff is in dealing with some of the 13 generics.
14 From examining the events, let me say a 15 couple words about the generic review process 16 before we focus on some of the specific type of 17 issues.
t 18 No rm ally the generic issues are manag ed 19 pr im a r il y by the d iv i s i on of safety technology 20 of NRC, generic issues may come to the staff 21 from any number of sources or from within NRC.
22 When a generic issue is identified, it is 23 first and immediately identified to the
-[} 24 operating reactors a s s e s sm e n t branch d iv i sio n 25 of licensing so that the staff of that branch, Cefaratti, Rennillo %
, ____._..... .. A MGilbeW1 Cmn Ramnars dUU
104 1 which is my branch, may look at it and
() 2 d e te rm i ne if there is some immediate safety 3 significance that the staff must act on very 4 promptly.
5 If there is not a matter of meeting 6 safety significance, it is then handled 7 primarily by the d iv i s i on of safety technology 8 and the issue will be evaluated and a decision 9 made whether staff resources should be .
10 committed to this particular issue.
11 Quite actively the organization and 12 effort may take several months, it involed
[^') 13 probably and I believe risk assessment and v
14 studies and a cost benefit analysis, at that 15 point they normally classify the issues as h i g h ,.
16 medium or low.
17 Because of lim i t a t i on on staff resources, 18 those that get classified as low are at this 19 tim e generally dropped.
20 Those that are classified as h ig h are 21 pursued as rapidly as we can within the bounds 22 of resources.
23 Medium are handled somewhere in between,
) 24 but the medium issues are not thrown into the G
25 box that is entitled dropped.

105 1 _Let me talk about how we.got to the term
([ ) 2 immediate generic issues and short term generic 3 issues as we dealt with the Davis-Besse Ev en t 4 of June 9th.
5 Within t h o s,e first couple of days after 6 the Event as the operating reactors assessment 7 branch was able to gain facts of the Event, 8 this was really in advance of the special 9 inv es tig a tion team publishing the report, we 10 did our best to make an assessment.
11 In other words, issues that we think we 12 snould pursue quite pr om p tl y and hopefully f')
v 13 within the next few months, these are the 14 issues that you see identified on this line.
15 Let_me say a couple-words about them, I 16 think in general they are quite 17 s el f- ex pl a n a to r y and we to uc hed on these issues 18 in previous discussion.
19 Potential ability to remove decay heat, 20 because of the questionability of AFWS, really 21 has.three subparts, the first subpart deals 22 with the possibility of common failure, that 23 they mig ht go close or be close and be stuck 24 and unable to open.
)
25 In other words, the 599-608 valve Cefaratti, Rennillo
& Matthews co- R.oo*.e -
106 1 difficulty that we are already aware of here at Davis-Besse.
) 2 3 MR. MICHELSON: Why isn't 4 that an immediate generic issue since the same 5 problem of valve adjustment pertains 6 throughtout the industry perhaps.
7 MR. WESSMAN: I think we 8 feel that there is the potential problem of 9 valve ad j us tm en t throughout the industry, we 10 felt that this had been pursued on a rapid 11 basis but not necessarily within the matter of 12 the first couple weeks.
~
( 'j 13 MR. MICHELSON: Not even the 14 matter of next few months, since I really don't 15 see it on your short term list either.
16 MR. WESSMAN: Yes, sir it is, 17 first item on the potential inability to remove 18 decay, three subparts, one is the valves, so it 19 is on the short term.
20 Perhaps I could have made the outline in 21 more detail, but I d id n ' t .
22 MR. MICHELSON: I must have 23 misinterpreted, you mean all valve problems 24 under that item then I'm happy.

107 1 that, r ig h t now first looking and foremost at ;
i
() 2 the decay heat aspect, the second aspect of the 3 inability to remove decay focuses on the l 4 turbines and turbine trip mechanism.
5 Obviously here at Davis-Besse we say 6 difficulty and ability to reset and dif ficul t 7 with the governor mechanism.
8 That aspect also included under the first 9 item.
10 Thirdly, under this item under the item 11 to remove decay heat is the item .related to 12 steam and steam rupture mi t ig a t ing systems.
f' 't 13 MR. EBERSOLE: You have
' <. )
14 skillfully avoided diversity in the need for 15 pumps. Why d id you do that?
16 MR. WESSMAN: I don't know 17 that I skillfully avoided it.
18 MR. EBERSOLE: You did.
19 MR. WESSMAN: From a generic 20 standpoint, Davis-Besse is the last plant that 21 does not have this electric pump, we are 22 focusing on Davis-Jesse from a plant specific 23 standpoint.

25 The second maj or short term generic issue Ceforotti, Rennillo
__.___ __ _ .. __& Matthews com Reconm
_ _. _ _ . . . _ - . . . _ _. . _..-.--;:.._..-_.-...-2 108 1 that we identified was the adequacy of I x _) 2 emergency procedures to deem in a situation 3 where quote drastic action m ig ht be required.
4 To take a look at the procedures relating to 5 that on a generic basis and see whether 6 criteria is clear and that the operators are 7 trained to properly initiate this cooling.
8 The third maj or item here deals with 9 physical security system constraints, this is 10 the third marriage of the short term items, to 11 get the equipment when you need to in a hurry.
12 Pr ior i za t ion of these issues is in
()
n 13 progress and my understanding nearly completely 14 and at that point.
I.
f 15 The division of safety technology will 16 g ive us recommendations whether these are h ig h ,
i 17 medium or low and at that point we'll start 18 down the fact of putting staff resources to 19 work on them.
! 20 I also would expect NRC plans to move 21 fairly rapidly, we think they are im po r t a n t and 22 staff said they are im po r t a n t , we are calling 23 them short term i t em s .
l ; 24 As part of our review we also identified 25 a number of issues under longer term generic l
Ceforotti, Rennillo
& Matthews coun Reponem (l __
109 1 issues. These are issues, we see issues that 2 can be allowed to proceed through the
'(v^}
3 relatively normal path of routine examination 4 and priorization and which really mean that can 5 be a number of months before priorization is j 6 really complete on these items.
7 The first five or so are derived from 8' NUREG 1154 and the last one and several on the 9 following' slide have been derived from the 10 issues identified to the NRC staff primarily by 11 the other members of NRC and in a couple cases 12 individuals outside of NRC.
em .13 I- d on' t think I would necessarily dwell D~
14 specifically on any of these.unless there is a 15 question dealing with them. Most of them I 16 think are relatti issues that we talked about.
17 MR. REMICK: I h'a v e a 18 question relating to the STA, does anybody know 19 whut the status is of the rule that would 20 enable the STA to become the second SRO on the 21 shift.
22 The last I k'n e w the commission was still 23 working on that, anybody know in the ind us tr y?
24 MR. WESSMAN: I'm sorry, I
,-t ,)
25 cannot answer that.

110 1 Next slide.
( 2 These ag ain , long term potential generic 3 issues, are pr im a r il y items that came from 4 other ind iv id ual s on the staff and are not 5 derived directly from reviews of NUREG 1154.
6 I would comment very briefly on items 10 7 and 11.
8 At this point this is the sum total of 9 our, at least from NRC's s tand po int of long 10 term generic issues, 11 l'd like to comment briefly on a couple 12 activities in a generic activity that are being
) 13 handled by other offices.
14 As you may be aware, INE has been working 15 on a bulletin that focuses directly on the
- 1. 6 proper operation of the motor operated valves 17 and which, again, systems back to the 18 difficulties with reopening the 599/608 valve, 19 valves that encounter a h ig h differential 20 pressure may not be properly set from the 21 standpoint of operators to open under all 22 circumstances in which they mig ht encounter.
23 This bulletin has been developed by INE 24 and reviewed by NRC and staff interchange on it,
(~')
25 and I believe to go to .t h e CRGR within the next Ceforatti, Rennillo - ' -

111 1 week or so.
, 2 MR. WESSMAN: If I m ig ht 3 suggest on the bulletin, it is my understanding 4 that the bulletin has not been t r a n sm i t ted from 5 INE to the CRGR for r ev iew but at the point INE 6 is satisfied with their own staff action and 7 submitted to the CRGR a copy will be made ;
8 available to ACRS, by next Tuesday they are 9 ready to do it with their own staff review, I 10 think that's the appropriate time.
1 1- A couple activities I have underway, the 12 INE is looking at the notification that was
()
13 made to the emergency response center v 'i a the 14 VNS phone network and the decl'aration of 15 emergency class that was made by the utility 16 and I believe they are developing an i.e. is in 17 this area regarding the licensee.
18 I also expect that they would look at 19 some aspects of AFAW turbine reliability and 20 some aspects of equipment malfunctions that are 21 identified in NUREG'1154 subsequent to the 22 completion of utilities who cause analysis 23 efforts and I think in part depending on NRC
(] 24 actions, in this arena that may feel.the issue,

7 I'd like to spend a few minutes, we will 8 have two hours Thursday afternoon, 1:45 to 3:45 9 and based on how things went this afternoon, 10 first if I look at the staff, I have a feeling t
11 based on the fact you still have much reviewing i
12 to do, probably one would be in much better I 13

18 not necesso _y go over every item, you m ig ht 19 get a question for a particular one, but pick 20 out the ones that you feel are more important 21 and say something.

.8 introductory remarks to bring them up to speed 9 and that m ig ht be just a very quick rehash of l
10 events, to bring up to mind what we are talking 11 about.
12 If licensee ag r ees , I m ig ht include some 13 of the major organizational changes that you
(')N w
14 made to save you time if you need to have 15 s om e b od y come up and present that, quickly 16 mention two or three of the items that you are 17 doing and point out to the committee that there 18 are other things.
'19. I think you should concentrate on what 20 you, what was the problem, what do you believe 1
21 is the root cause and what is your proposed fix.
22 Basically I think the latter parts of 23 your presentation were of that type, where you r^' 2:4 are telling people that this is what the N~)3 l 25 problem was and this is how we ate going to fix Cefaratti, Rennillo =

v l 2 on that.
3 I think you should concentrate on not j 4 telling people how you . d id it but what you d id .
5 Those org an i za t i o nal thing s and committees and 6 numbers of committees and things are im po r tan t 7 but in the t im e span, it probably would be 8 better to concentrate on root causes and fixes 9 and be prepared to answer questions on that.
10 That would be my suggestion.
11 I would suggest that your handouts be 12 placed in the order they are going to be
()
r, 13 presented to save the committee members from 14 having to flash around.
15 If they can see what is coming up, 16 s om e t im e s they can look ahead, that is coming 17 up, I won't ask a question at this point in 18 time.
19 Today's was som ewh a t out of order, we had 20 to go back and forth.
21 I would suggest that you keep the number 22 of presenters to as few as you can. I think we 23 always lose t im e if we have many presenters, I i')J 24 think you have to dictate there what you feel Lj 25 comfortable with.

1 I think those are the general comments.
L[ws) 2 You.are going to have to cut down 3 considerably and you will have lots of 4 questions, I won't have any more luck with the 5 full committee than I had with the subcommittee, 6 I can assure you, so, we' ll be on a tight arm 7 schedule. The chairman was sitting nex t- to me, 8 I asked him, can we possibly get more t im e? He 9 said it is not available, we'll have to stick 10 to the two hour time span and it will be my job 11 to try and keep ev er ybod y wi thin that.
12 We are fortunate we have a fair
/^3 13 representation here, a third of the G:
14 subcommittee.
15 They had a chance to ask a number of 16 questions. I would ask them if they already 17 asked the question that unless they feel it is 18 im po r t a n t to bring it out in the full committee, 19 that they restrain repeating questions unless 20 they feel it is im po r t a n t from that s tand po int .
l 21 It is a lot better to get to the 22 nitty-gritty aspects of what you are going to
'23 do, how you do it is your business.
24 Does the staff have any comments or word s j-
~,.
25 of wisdom or suggestions?
