3 CHAIRMAN SMITH:
We were wondering if the 4 testimony yes erday of Mr. Keimig and Haverkamp included the 5 memorandum of March 13, 1981 from Keimig to Swanson.
If it 6 did not, we think that was an excellent treatment of the 7 problem.
It completes the record and should be included.
8 Do you recall, Mr. Tourte11otte?
9 MR. TOURTELLOTTE:
It was supposed to have been 10 there.
If it was not, why, we will provide it.
11 CHAIRMAN SMITHS If it is not. we can put it in 12 some other time, I suppose, but I think it should be part of 13 the evidentiary record.
14 MR. TOURTELLCTTEs Okay.
I thought it was part of 15 t ha t package that I handed to the Reporter.
16 DR. LITTLE:
They were included in the package, 17 but after thinking about it, we could not determine whether 18 this vss attached to the testimony,or just happened to be 19 packaged along with the testimony.
20
'R.
TOURTELLOTTE:
It was attached to.the 21 testimony as a part of th e testimony.
It was supposed to 22 be.
I will work it out with the Reporter.
If it is not, 23 well --
24 CHAIRMAN SMITH:
Fine.
I mean, I see ne problem 25 ALDERSON AEPCRTING COMPANY,!NC, 400 VIAGINIA AVE., S.W., WASHINGTCN. D.C. 20024 (202) 554-2345 y

16,489 1 so long as you remember it was part of it.
'de will check 2 the transcript when it comes in.
3 MR. TOURTELLOTTE.
Incidentally, Mr. Chairman, two 4 other things.' One is that I attempted to get a witness here 5 on IEEP so it would help fill up the time and tried to get 6 his schedule rearranged.
It turns out it doesn't make any 7 difference because he is ill anyway, and so I could not do 8 tha t, but I tried.
9 And the other thing I wanted noted in the record 10 is I have made a transmittal to Mr. Basdekas, the 11 transmittal posing the questions as I understood those 12 questions should be posed after our discussion on the record 13 last week, and I have also discussed it with him on the 14 phone, and he tells me that he will have an answer to us by 15 April 10, perhaps before.
So I will report back as scen as 16 I car..
17 Also, one other thing.
The Board indicated that 18 they had an interest in knowing w h a,t items that were 19 outstanding were going to be resolved or in some way may 20 affect the hearing, and I have had Mr. Gray and Cutchin 21 working on this for the past several days with the technical 22 staff and with FEMA staff, and we will report to the Board 23 just as soon as we have an answer, but we frankly just do 24 not have the answer yet.
And I do not really have a good 25 enough indication of how those issues might be resolved or ALDERSoN REPORTING COMPANY,INC, 400 VIRGINIA AVE., S.W., WASHINGTCN. O.C. 20024 (202) 554 2345

wha t might be required to even give you an intelligent 2 questimate richt now, but I will report as soon as I know 3 anything.
4 CHAiRNAN SMITH:
Is there any other preliminary 5 business?
6 MR. BLAKE:
Mr. Smith, I have one.
Since Dr.
7 Jordan is here today, when Mr. Koppe was here, Dr. Jo rd an,
8 at the end of his presentation at transcript page 13,412, 9 you arked Mr. Koppe to do a couple of things.
The first was 10 to 11entify f or you the sources of the numbers that he had ti used from WASH-1400.
I will provide you the answer from Mr.
12 Koppe on that.
13 The actual calculations of the numbers Mr. Koppe 14 reports are described in Appendix II to WASH-1400, and 15 within Appendix II the system failure rates which he quoted 16 are presented on the following pages.
For diesel 17 generators, on page --

You also asked him at that same transcript page to 2 verif y again indeed that the numbers corresponded to the 3 challenge rates in WASH-1400, and he reports tha t he has 4 reviewed WASH l400 again to verify that the numbers that se 5 quoted indeed represen t the system failure rates.

LICENSEE'S TESTIMONY OF CHARLES HARTMAN AND JOSEPH A. TORCIVIA ON DIESEL LOADING IN THE EVENT OF LOSS OF OFF-SITE POWER
OUTLINE i
Previous witnesses have testified that loading of the pressurizer heaters to the diesel genera *or may be desirable both in the case of a loss of off-site power condition and in i
the case of a loss of off-site power accompanied by a small break in the reactor coolant system.
This testimony demonstrates that a single diesel generator has sufficient capacity to j
accommodate connection of the pressurizer heater load in addition to all safety-related loads required in each of the two cases.
This testimony also explains how the si=e of individual loads has been calculated.

INTRODUCTION This testimony, by Mr. Charles Hartman, Lead Electrical Engineer, Plant Engineering, GPU, and Mr. Joseph A. Torcivia, Senior Project Engineer, GPU, supplements previous testimony on UCS Contention No. 4 (Connection of Pressurizer Heater to Diesel) and responds to the Board's request for further information on diesel loading in the event of a loss of off-site power.
Mr. Hartman's testimony covers the loading sequence and cumulative loads for two cases - loss of off-site power only and loss of off-site power combined with a small break LOCA.
Mr. Torcivia's testimony explains how the size of the individual loads enumerated by Mr. Hartman has been calculated.
TESTIMONY BY MR. HARTMAN:
Figure 1 attached to this testimony shows the size and timing of loads which would be connected.to the diesel generator in the event of a loss of off-site power only.
Figure 2 provides similar information for the case of a loss of off-site power combined with a small break L'OCA.
For both cases B Diesel is assumed tc be unavailable.
Thus all loads i
are loaded on A Diesel.
If both diesels are available the load would be divided cetween the two diesels and the load on either diesel would be less than the loading shown.
l
Tables A and B, also attached to this testimony, present in tabular form the same information as Figures 1 and 2 and, in addition, supply a detailed listing of each of the loads connected to the diesel generator.
Previous witnesses have testified that loading of a pressurizer heater group to the diesel generator may be desirable both in the case of a loss of off-site power condition and in the case of a loss of off-site power accompanied by a small break in the reactor coolant system.
Figures 1 and 2 and their associated tables demonstrate that the diesel generator, rated at 3000 kw, has sufficient capacity to accommodate connection of the pressurizer heater load in addition to all safety-related loads required in each of the two cases.
The pressurizer heaters are shown in Figures 1 and 2 to be added two hours after the loss of off-site power.
DISCUSSION OF FIGURE 1 The loading sequence shown for the case of a loss of off-site power only includes all safety-related loads required for that event.
Note that Figure 1 also includes a number of non-safety related loads which, in the case of a LOCA, would be automatically disconnected upon receipt of an ES signal.
The loads in Figure 1 include valve loads which are required for two minutes or less before they complete their function and stop.
For simplicity's sake all valves are shown as instantaneous loads and are discontinued after ten minutes..
i i
1 Safety-related loads are defined for purposes of this testimony as those required to achieve and maintain the Unit j
in a safe shut-down condition or to support safety-related equipment.
The major loads for those functions are:
a.
Makeup Pump (HPI)
I b.
Motor Driven Emergency Feedwater Pump (although turbine driven Pump is sufficient) c.
Decay Heat River Pump i
d.
Nuclear Services River Water Pump
]
e.
Nuclear Services Closed Cooling Water Pump f.
Decay Heat Closed Cooling Water Pump (LPI) g.
Control Building Ventilation h.
Reacter Building Ventilation i.
Inverters j.
Battery Chargers k.
Radiation Monitors 1.
Area Lighting m.
Spent Fuel Cooling (required after 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />)
Major loads which are not safety-related but which tre desirable for equipment protection or ease of operations are:
a.
Instrument Air Compressors b.
Pressurizer Heaters c.
Intermediate Closed Cooling Water Pump d.
e.
Main Turbine Turning Gear and Lift Oil Pumps f.
Substation Control Power g.
Screen Wash Pumps 3-
h.
Penetration Cooling Fan i.
Sump Pumps Not all of the safety-related loads would necessari!y be required for the entire duration of the loss of off-site power.
For example, assuming the availability of the Turbine Driven EFW Pump, the Motor Driven EFW Pump can be turned off.
Figure 1 shows this load change after 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> although switching to the Turbine Driven EFW Pump could be accomplished at any time after the loss of off-site power.' Another load which could potentially be shed (but which is not shown to be turned off in Figure 1) is the Makeup Pump after the RCS has been cooled down to less than approximately 320 psig and 250'F.
The operator could also reduce load on the diesel by realigning Nuclear Service Closed Cooling Water services to the Makeup Pump and then turning off Decay Heat Closed Cooling Water and Decay Heat River Water Pumps.
Actual loads for major pumps would probably be less than the maximum loads shown on Figure 1.
For example, in the no LOCA scenario the Makeup Pump would be operating at about 120 gpm and would require 414 kw rather than 561 kw.
DISCUSSION OF FIGURE 2 Figure 2 loadings are based on small break si=es where the break is not sufficiently large enough to depressurize the RCS within a two hour period to the Low Pressure Injection System operating range.
In larger break sizes where the Reactor
-4_
s Coolant System depressurizes to Low Pressure Injection System operating range within the first two hours, the pressurizer heaters would not be of value.
The loading sequence shown in Figure 2 includes all safety-related loads required for a loss of off-site power coupled with a small break LOCA.
The Reactor Building Spray Pump is assumed not.to be operating since it starts when reactor building pressure is 30 psig.
Small breaks which will not depressurize the Reactor Coolant System to the Low Pressure Injection range (and therefore possibly call for the use of the pressurizer heaters) would not result in reactor building pressures as great as 30 psig.
The safety-related loads for loss of off-site power with small break are automatically connected in a five block sequence by block loading timers and are sinilar to the loss of off-site power situation, except that the following two additional loads automatically start:
a.
Decay Heat Removal Pump (auto starts, but is not required until RCS pressure is less than 300 psig.)
b.
A second Reactor Building Ventilation Unit Fan.
The following loads are automatically tripped to reduce diesel loading:
a.
Screen Wash Pump b.
Instrument Air Compressor c.
Main Turbine Lift Oil Pumps d.
e.
Reactor Coolant Pump Lift Oil Pump f.
Spent Fuel Cooling Pump g.
Intermediate Closed Cooling Water Pump h.
Borated Water Storage Tank Heater i.
Pressurizer Heaters (if connected to the class lE Bus)
Some of the loads that are automatically tripped may be manually started at a later time consistent with diesel loading.
Examples of such loads are Instrument Air Compressor and Spent Fuel Cooling Pump, which are shown to be manually added in Figure 2 after tripping the Motor Driven EFW Pump.
BY MR. TORCIVIA CALCULATION OF LOADS This portion of our testimony explain; how loads were calculated for the individual items of equipment listed in Tables A and B.
The majority of loads on the diesel g,enerators are induction motors.
The following formula has been used in calculating motor loads and converting Brake Horsepower (B.H.P.) ratings to Kilowatt (K.W.) ratings:
B.H.P. X 0.746 Load (K.W.)
=
sfficiency For motors used to operate pumps, B.H.P.
value is taken from the manufacturer's pump curve where available and from the name plate rating of the motor where pump curves are not available.
Since motors are offered commercially in standard sizes, it is not uncommon to purchase motors with a higher rating than required to operate the pump and the full horsepower rating of the motor is not used at the design operating point. Service factor of the motors has been taken as 1.
The factor of 0.746 is a standard factor for converting horsepower to kilowatts.
Motor efficiency data has been taken fromWestinghouseandRelianceAppliedEnginebringbatafor various size motors.
Following is an example calculation of the motor load for the Reactor Building Emergency Cooling River Water Pump, RR-PlA:
Motor Nameplate Rating = 400 H.P.
I Pump Curve Rating
= 380 H.P.
Efficiency
= 0.92 0
08 Load (K.W.)

=
09 Pure resistance loads, such as the pressurizer heater, are identified by their simple kilowatt rating.

CHAIRHAN SMITH I as reminded abo It a problem 2 that the Board has recently discussed, Mr. Tourte11otte.
It 3 would be very helpful if the Staff would put on the first 4 page cf its testimony the date that the testimony is 5 submitted.
6 I realize that very often the testimony is 7 accompanied by a cover letter with the date on it, but 8 sometimes the testinony gets separated from the cover 9 letter, and it is helpful for us to know when we read the to testimony just how current it is.
C' it would be helpful if 11 all parties would ' ave some place in the testimony the date 12 it was prepared ar.
Treferably on the first page.
- 13 The Licensee has used the method of putting it up 14 in the upper righthand corner which is helpful to us.
15 MR. TOURTELLOTTE:
You want the date that it is 16 admitted into the record or the date that it is submitted?
17 CHAIRMAN SMITH:
The date that it is submitted and 18 the reason -- just wha tever date is, convenient to the Staff 19 to give us some idea of its currency so that we know at a 20 glance whether the testimony has taken into account 21 subsequent developments in the case.
22 MR. TOURTELLOTTEt We try to do that in every 23 case.
I do not kno. specifically 24 CHAIRMAN SMITH:
Well, it is not well, for 25 example, I am looking at Mr. Curry and Vermeil's testimony, ALDERSoN REPORTING COMP ANY,INC, 400 VIRGINIA AVE., S.W., WASHINGTON, D.C. 20024 (202) 554-2345
16,u95 1
and it is not there.
2 MR. TOURTELLCTTE:
I noted yesterday Keimig and 3 Haverkamp did have it on theirs, but I guess it must have 4 been overlooked'with-Vermeil and --
S CHAIRMAN SMITH:
I am looking at Haverkamp's and 6 Keimig's and it did, yes, tha t is tignt.
7 Mr. Dornsife, do you have questions?
8 MR. TROWBRIDGEs Mr. Chairman, I would ask one 9 supplemental question only.
10 BY MR. TROWBRIDGE:
(Resuming) 11 Q
Mr. Hartman, on page 1 of th e testimony you 12 indicate that the diesel loading tables and figures have 13 been prepared on the assumption that one diesel is not 14 available and that is the B diesel.
Would there be a 15 siqnificant difference in these tables if you had.ssumed 16 that the B diesel was available and the A diesel was not?
17 A
(WITNESS HARTMAN)
No, sir.
There was no 18 siccificant difference.
19 MR. TROWBRIDGE:
Thank you.
That is the only 20 question.
21 CHAIRMAN SMITH:
Mr. Dornsife.
22 MR. DORNSIFE Mr. Chairman, I was sorry I was a 23 few minutes late.
Is Mr. Pollard going to be here to 24 question on this issue?
25 CHAIRMAN SMITH:
Apparently not.
The last word we ALOERSON REPORTING CCMPANY. INC.
4 400 VIRGINIA AVE., S.W., WASHINGTON O.C. 20024 (202) 554 2345 s
16,496 1
had last evening was that he may or may not come.
2 MR. TR04 BRIDGE:
Our word through Tom Baxter is 3 that UCS will not be represented this afternoon.
4 MR.'DORNSIFE4 I am sorry.
Will not?
5 MR. TROWBRIDGE:
Will not be represented this 6 afternoon.
7 MR. DORNSIFE:
How about tomorrow?
8 MR. TROWBRIDGE:
We expect them to be here for 9 emergency feedwater tomorrow.
I have no other intelligence.
10 MR. DORNSIFE:
I just have several short carryover 11 questions from the original questioning on'this testimony.
12 CROSS EXAMINATION 13 BY MR. DORNSIFE:
14 0
Mr. Torci'via, isn't it true th,a t induction motors 15 when they start have a large in-rush current?
16 A
(WITNESS TORCIVIA)
That is correct.
17 0
What is typically the magnitude of the in-rush 18 current?
19 A
(WITNESS TORCIVIA)
From five to six times on the 20 average.
21 Q
And let's say the diesel generator was near its 22 maximum continuous capacity and a large induction motor were 20 started.
What effect would that have rn the diesel?
24 A
(WITNESS TOBCIVIA)
Well, to begin with, to 25 preface that question, before the diesel can be at its ALDERSoN REPORTING COMPANY, INC, 400 VIRGINlA AVE., S.W., WASHINGTCN. D.C. 20024 (202) 554 2345
16,497 1 capacity, no such motor would be started.
It must be 2 assumed tha t the motor has been lost and restarted.
On that 3 basis the diesel will be able to pick it up.
In other 4 words, the in rush current will be of such a value that the 5 diesel voltage will dip quickly and come right back up as a 6 result of the action of the regulator.
7 0
Say hypothetically the diesel were operated for 8 some reason right at its 2,000 hour0 days <br />0 hours <br />0 weeks <br />0 months <br /> -- 3,000 kw capacity and 9 right below that, and the induction motor was started.
How 10 high would the in-rush current need to be to cause any 11 adverse or could it ever cause any adverse problems with the 12 diesel picking it up?
13 A
(WITNESS TORCIVIA)
Well, I think you must i
14 recognize that I do not profess t a be a diesel expert, but I 15 will say this, based on the electrical characteristics of 16 the diesel which in turn is the generator, in essence, the 17 generator will be f ully capable of accepting the in-rush 18 current of any motor at any time within the capacity of the 19 diesel.
20 0
What is the rating of the diesel typically based 21 on, the time rating?
22 A
(WITNESS TORCIVIA)
I presume you are speaking in 23 terms of the 2,000 hour0 days <br />0 hours <br />0 weeks <br />0 months <br /> rating.
24 Q
Yes.
25 A
(WITNESS TORCIVIA)
Again I want to preface that.
ALCEASON AEPORTING COMPANY. INC, 400 VIRGINIA AVE., S.W., WASMNGTON 0.C. 20024 (202) 554 2345
16,498 1
I am not a diesel expert, but I did have some discussions 2 with diesel people, and their estimation on that point is 3 based on the interest'of having the bearings checked out, the oil checked) no major modifications or changes.
They 4
5 are not talking about a major overhaul.
They are talking 6 about clearances of shafts and bearings and things of that 7 nature.
That is what I have been told.
The diesel would be 8 just as good in 2,500 hours0.00579 days <br />0.139 hours <br />8.267196e-4 weeks <br />1.9025e-4 months <br /> as 2,000 hours0 days <br />0 hours <br />0 weeks <br />0 months <br />.
Two thousand 9 hours1.041667e-4 days <br />0.0025 hours <br />1.488095e-5 weeks <br />3.4245e-6 months <br /> is like a 5,000 mile checkup on your o'il in your 10 engine.
It is cae of those figures.
That is the impression 11 they lef t me with.
12 0
Would that include the half hour rating?
Is that 13 of any special significance?
14 A
(WITNESS TORCIVIA)
In terms of a half hour 15 rating, I never really questioned them in that sense in terms of what it would do to the engine itself.
I may say 16 this, that the welfare of any piece of equipment is 17 primarily based on temperature rise.
For example, em far as 18 the generator is concerned, that ca'n a cc e p t an extendea 19 period of overload before it has a large temperature rise.
20 In my opinion the diesel being involved with the 21 temperature rise of the oil, the bea rings, those points, it 22 would depend on a temperature rise.
It is entirely possible 23 to run that 20 percent overload for hours and hours if the 24 temperatures do not rise beyond its set point.
That is all 25 ALCERSoN REPORTING COMPANY,INC.
400 VIRGINIA AVE., S.W., WASHINGTON, D.C. 20024 (202) 554 2345
16,499 1
I do know about the diesel.
2 Q
If the diesel, let's say, were overloaded and 3 either because of instrument error or some other reason the 4 operators vers not immediately aware of it, are there alarms S in the control room which would indicate pending problems 6 before the diesel would trip on some condition?
7 A
(WITNESS TORCIVIA)
I think that question --
8 A
(WITNESS HARTMAN)
I think perhaps I can answer 9 tha t.
There are overload alarms in the control room.
There 10 are also temperature alarms from the diesel.
Typically when 11 the diesel is running we also take readings no less 12 frequently than hourly to assure that oil temperatures, 13 coolant temperature, exhaust temperatures are in the 14 required band.
15 C
So you feel the operator could have sufficient 16 tim e to trip off selected loads if these conditions were in 17 fact approaching or imminent or in fact occurring.
18 A
(WITNESS HARTMAN)
Yes, s,ir.
19 M3. D'JRNSIFE:
I have no mere questions.
20 CHAIRMAN SMITH:
Mr. Tourtellotte.
21 3Y MR. TOURT EL10TTE.
22 C
When there is an emergency, does the diesel start 23 automatically or manually?
24 A
(WITNESS HARTMAN)
I believe the question was when 25 there is an emergency does the diesel start automatically.
ALDERSoN REPCRTING CCMPANY, INC, 400 VIRGANIA AVE., $/N., WASHINGTON, D.C. 20024 (202) 554-2345
16,500 1
Q Right.
Or manually.
2 A
(WITNESS HARTMAN)
The diesel starts automa tically 3 on a loss of voltage to the bus or on an engineered 4 safeguard sigd 1.
5 Q
Okay.
If there appea red somewhere in your 6 testimony that it was to start manually within 15 seconds 7 would that be in error after the -- into an emergency?
8 Would it be in error for someone to suggest that it was a 9 15-second manual start af terwards?
10 A
(WITNESS HARTMAN)
Sir, could you direct me to the 11 portion of the testimony?
12 Q
As I recall, in one of the tables it talks about 13 15-second manual start.
14 A
(WITNESS TORCIVIA)
This testimon y here ?
15 0
Yes.
16 (WITNESS TORCIVIA)
Oh, we do not mean the manual 17 start in terms of starting the diesel.
We mean in terms of 18 applying the lead to the diesel.
19 0
Okay.
Can you explain that then?
20 A
(WITNESS TORCIVIA)
I beg your pardon.
21 0
Can you explain that, applying the load to the 22 diesel?
23 A
(WITNESS HARTMAN)
Sir, I believe I can address 24 that question.
When the diesel automatically starts, some 25 loads are directly connected to the diesel or vculd sta rt t
i ALDERSON REPORTING COMPANY,INC, 400 VIRGINIA AVE., S.W., WASHINGTCN, D.C. 20024 (202) 554-2345
16,501 1
a utomatically d ue to a level pressure or some other signal.
2 I am referring now to the loss of off site power situation.
3 Following that, those automatically started loads, 4 the operator 5 uld sta rt manual loads.
The time that we 5 picked, the 15 seconds, there is an arbitrary, somewhat 6 arbitrary time which we have selected, considering that the 7 operator would not start the load any earlier than that.
It 8 could have been shown later and perhaps would be more 9 realistically shown la ter.
to C
I guess the one I am referring to is on "able A, i
11 number 5.
12 A
(WITNESS HARTMAN)
Yes, sir, that is the makeup 13 pump, and we show that starting in 15 seconds.
There is no 14 -- that would be a manual start.
There is no requirement 15 that it be started at 15 seconds.
That is a time we picked 16 for this chart, because we felt that it was a reasonable 17 amount of the earliest time tha t an operator could do that.
18 C
Where is the operator at,the time that he would 19 have to do that?
20 A
(WITNESS HARTNAN)
There are two considerations on 21 starting the makeup pump.
Cne would be restoration of f uel 22 injection to the reactor coolant pumps.
The other is to 23 maintain pressurizer level.
And I do not have an exact time 24 for that.
However, the pressurizer, for a reactor trip the 25 pressurizer does not go empty.
In o th er words, it would ALDERSoN REPORTING COMPANY,INC.
400 VIRGINIA AVE, S.W, WASHINGTON. D.C. 20024 G02) 554 2345
16,502 1
remain on scale, and you would have to restore makeup prior 2 to cooling down.
3 0
Well, the reason I am asking the question is I 4 seem te recall in some earlier testimony -- and this is 5 simply my recall; I do not have any transcripts to cite --
6 but as I was looking at that, it seems like previous 7 testimony indicated there was quite a distance between the 8 place that one would manually start loads and where the 9 operator would be loca ted, and 15 seconds seemed like a 10 terribly short time.
11 So I guess my question is directed as to whether 12 15 seconds is unrealistic, and even if it is unrealistic, 13 does that have any safety significe.'e?
14 A
(WITNESS HARTMAN)
I thin _k that is a very short 15 time.
I would not expect the operator to respond tha t 16 quickly or certainly not any more quickly than that.
The 17 only effect from the standpoint of diesel leading would be 18 that these loads would appear later on in tre chart.
19 MB. TROWBRIDGE2 let me suggest, Jim, you may have 20 been referring to previous testimony about loading the 21 pressurizar heaters manually or connecting where one would 22 have to go outside the control room to another location to i
23 accomplish that.
24 I think the que= tion here for Mr. Hartman was 25 essentially as to the makeup pumps where is the operator l
ALCERSCN REPCRTING COMPANY, INC.
400 VIRGINIA AVE., S.W., WASHINGTON 0.C. 20024 (202) 554 2345 i
2 16,503 1
when he adds the makeup pumps to the diesel.
2 WITNESS TORCIVIA:
Where is the control switch?
3 WITNESS HARTMAN:
The control switch is on the 4 center console.
The opera tor would be nearby at the time 5 this occurred.
The 15 seconds is not meant to imply that 6 action is required in that time.
It was a somewhat 7 arbitrary time that was picked with the intention of showing 8 that it could not be any earlier than that.
9 BY MR. TOURTELLOTTE:
(Resuming) 10 Q
But then what you are telling me now is he is 11 within a physical proximity of'the switch such that he could 12 reach it within 15 seconds if he chose to.
13 A
(WITNESS HARTMAN)
Yes, sir, I believe that is 14 true.
15 A
(WIT"ESS TORCIVIA)
That is right.
16 ER. TOURTELLOTTE:
I have no other questions.
17 BOARD EXAMINATION 18 BY DR. JORDAN:
19 C
When you say the diesel has a rating of 3,000 20 kilowatts does that tell you the type of load?
Is that a, 21 resistive load or is it a load with a power factor of a
.2 22 or something like that?
Do you know?
23 A
(WITNESS HARTMAN)
Sir, that 3,000 kw rating is at 24 a
.8 power factor.
25 0
And has it been determined tha t the loads that you ALDERSON REPORTING COMPANY,INC, j
400 VIRGINIA AVE., S.W., WASHINGTCN, D.C. 20024 (202) 554 2345
16,504 1
are putting on the db m.2 will indeed produce a load wi th
.8 2 or larger power factor?
3 A
(WITNESS HARTMAN)
The power f actor of the load 4 would vary depending on the ratio of motors to resistance 5 heaters and other sorts of loads.
The power factor at light 6 load considering pumps being in a throttled condition could 7 approach or perhaps exceed I am sorry -- be a lower power 8 factor than
.8.
However, in that case the kw load would be 9 less, and it would be acceptable within' the capability curve 10 of the ' machine to have a power factor lower than
.8.
11 Q
Well, yes, but your diagram shows the time when 12 the various loads do come on, some of which a re resistive, 13 some have power factors,
.8,
.7, whatever.
Now, do you take 14 that into account and do you know, therefore, tha t at any 15 time that the power factor will be indeed
.8 or above during 16 this loading curve?
17 A
(WITNESS HARTMAN)
Yes, sir, we did consider that 18 in this chart, and I believe the po,wer factor would be less 19 -- would be greater than
.8.
20 Q
I see.
Fine.
That is what I van ed to know.
21 The loads that you have shown in your tables and 22 figures I presume are calculated on the basis of the known 4
1 23 ratings of the various machines, the efficiencies and so 24 forth.
25 Now, is there ever an occasion in which you test ALCERSoN REPORTING COMPANY,INC, 400 VIRGINIA AVE S.W WASHINGTON. O.C. 20024 (202) 554-2345
16,505 1
or simulate an offsite pcwer f ailure and actually have a 2 recording of the loading of the diesels so tha t you know 3 that the numbers -- your estimates, calculations are 4 accurate?
5 A
(WITNESS HARTMAN)
There is a refueling interval 6 surveillance test where we simulate a loss of offsite power 7 concurrent with actuation of the engineered safeguard 8 signal, and we have -- we do record the megawatt lead on the 9 diesel during that test.
That is recorded manually from the 10 meter in the control room.
11 Q
If that has actually been done, then do those 12 numbers check out well with the numbers that you have on the 13 figures here.
The figures that you have shown, the tables,
~
14 I believe, are calculated numbers.
15 A
(WITNESS HARTMAN)
Yos, sir.
16 0
Now, how did the experimental numbers then check 17 with the calculated figures?
18 A
(WITNESS HARTMAN)
The lo,ad during th e test is 19 much lower than the calculated numbers.
One reason for that 20 is the fact that many of the pumps are running at recirc 21 flow rates rather than at the full flow rates, full design 22 flow rates assumed in this study.
23 0
Upon loss of power are all of these loads -- well, 24 many of these pumps I presume and engineered safety features 25 are normally operating, is this correct, and upon a loss of ALOERSoN REPCRTING COMPANY,INC, 400 vtRGINIA AVE., S.W WASHiNGTCN, O C. 20024 (202) 554 2345
16,506 1 power those loads are dropped.
2 A
(WITNESS HARTMAN)
Yes, sir.
3 Q
And at that time then the diesels are restarted, 4 and that is th' first thing tha t happens upon a loss of 5 power, is that right, that automatically the diesels are 6 started.
7 A
(WITNESS HARTNAN)
Yes, sir.
8 0
And then is there a timer which times the loading 9 cycle or is.that all done by operator?
10 A
(WITNESS HARTMAN)
There are many directly 11 connected loads as shown on our table.
There is one timer 12 that is associated with the motor-driven emergency feed 13 pump.
With the exception of that timer, the loads are 14 manually applied.
15 Let me perhaps clarify that a bit farther.
The 16 engineered safeguard loads which were previously running, 17 for example, if a nuclear service closed cooling pump might 18 have previously been running, there, is an automatic start h
19 circuit there that the standby pump would start.
In th=+
20 case it has been shown as directly connected or 21 automatically starting load.
It does not have a specific 22 time delay af ter the diesel breaker has closed.
It is shown 23 as starting immediately.
24 Q
But you don't want that to happen, do you?
Oon't 1
25 you want the diesel to get up to full speed prior to the ALDERSON REPCRTING COMPANY,INC, 400 VIRGINIA AVE., S.W., WASHINGTON, D.C. 20024 (202) 554 2345
16,507 1
connection of any load?
2 A
(WITNESS H ARTM AN )
The diesel does come up to full 3 speed.
The breaker closes when it reaches operating voltage 4 and speed.
5 Q
I see.
So there is no power connected to the bus 6 until the breaker closes, and so therefore, none of these 7 loads can come on, but as soon as that breaker closed, then 8 these loads that are normally connected are picked up at 9 that time, is that correct?
10 A
(WITNESS HARTMAN)
Yes, sir, that is correct.
11 0
How does that show on the figure?
12 A
(WITNESS HARTMAN)
That is shown on Table A in 13 block -- in section 1 and 2.
They are labeled directly 14 connected and autostart loads and autoapplied loads, 15 immediate.
16 C
So there is then -- and this shows now on the 17 figure at time zero, and by time zero, however, that is the 18 time at which the breaker closes, i,s that right?
19 A
(WITNESS HARTHAN)
Yes, sir.
20 Q
Not the time at which the power is lost.
21 A
(WITNESS HARTMAN)
Yes, sir.
It is the time at 22 which the diesel breaker closes.
23 0
All right.
That was not clear to me from the 24 diagram.
And so, therefore -- I see.
So a t that time, at 25 that instant one picks up instantly a load from Figure 1 of ALCERSON REPCRTING COMPANY,;NC, 400 VIRGINIA AVE., S.W., WASHlWTCN. D.C. 20024 (202) 554 2345
16,506 1
921 -- let's see.
That is kilowatts.
2 A
(WITNESS HARTMAN)
Yes, sir.
3 0
All right.
4 Now are you saying that even under a worst case 5 situation, assuming that the pumps are running full 6 capacity, and you mentioned that some of them would not be 7 running necessarily at full capacity but under a worst case 8 situation, that the maximum load tha t would be connected and 9 be required to be connected to the diesel, a single diesel, 10 would be less than the 3,000 kilowatts.
11 A
(WITNESS HARTMAN)
Yes, sir, that is correct.

I might just say that ! a pprecia te 23 the response that the licensee and the witnesses have 24 given.
I thought they did an exceptionally good job 25 rescending to s11 concerns.

6' DR. LITTLE:
I did have one comment I wanted to 7 make for the record in reference to yesterday's discussions 8 with health physics.
In the case of Ms. McAllister I was 9 not intending to personally criticire her when I was talking 10 to Mr. Neeley.
On the contrary, we felt that she was quite 11 capable, hichly motivated, enthusiastic about her work; and 12 the questions arose because of the apparent dissimilarity of 13 her background to her present function, and this appears to 14 be the type of thing that she will be capable of upgrading, i
15 upgrading her qualifications by additional training in the 16 area of health physics or radiological hygiene.
17 MR. BLAKE:
Dr. Little, I appreciate your makino 18 that comment because I wondered -- I obviously -- it was not to a stacked deck.
I went out and picked the lowest instructor 20 I cocid find to bring to talk with you.
Cuite frankly, 21 during some of the questioning I wondered if you had not 22 really wanted a higher class of instructor to maybe talk to 23 the rad technicians.
If you want to talk to somebody like 24 that, I will bring another one.
25 DR. LITTLE:
Well, I was not --

I was personally interested in seeing 3 just wha t we saw, what type of person is responsibir. for 4 teaching the 6eneral workers in regard to radiation 5 principles.
6 MR. BLAKE That was our intent.
7 DR. LITTLE:
The dissimilarity in background and 8 present function is what aroused questions in my mind.
