SUMMARY

AND CONCLUSIONS The purpose of this evaluation is to justify continued operation of Prairie Island Unit.s 1 and 2. During a.recent NRC procurement audit, concern was raised over the use of used molded case circuit breakers (MCCBs) in certain safety-related applications. l 2

2 In response to these ' concerns, the following can be said:

1. The breakers were not tampered with 2.- The breakers were tested satisfactorily l

3. The breakers do not affect the ability to safely shutdown the plant Due to the procurement audit and other concerns raised over substandard electrical parts (IEIN 88-19 and IEIN.88-46) a visual inspection was made of eight breakers from the same purchase order that have not been installed. All have a 2 1/2" by 1/16" slot machined into each side of the upper half of the casing where it mates.with the lower half. All have are chute ventilation screens on the line side. All have the upper and lower halves of the casings riveted together. None show significant signs of damage. None show scratches or marks beyond what would be expected from normal handling. NSP believes there is no external pq evidence indicating that these breakers have ever been il disassembled. ,

.All the breakers have been tested. Except for one MCCB, all passed the test. The MCCB that failed was not used. The reason'these specific breakers were needed was Appendix R circuit coordination.

The test demonstrated the breakers met the requirements for this application. All the breakers used passed the test and, therefore, satisfied the needed circuit protection.

One or more of the breakers will be dismantled and inspected. NSP is in the process of locating an expert on GE MCCBs. Then in the presence of representatives from NSP, NRC and the MCCB expert, one or more breakers will be dismantled and inspected. This inspection will provide additional confidence that the breakers have not been modified from original factory specifications.

I This evaluation examines:  !

1. Why the breakers were installed j i

2. A general assessment of what effect breaker failure I would have on plant safety I

3. A detailed look at the application of each breaker and what effect its failure would have on plant safety To summarize, the breakers were installed to meet Appendix R circuit coordination requirements. Used breakers were installed because the breakers needed to coordinate are no longer made.

The'used breakers were located with the assistance of General Electric, the original equipment manufacturer.

NSP believes the breakers can fulfill the design function. There is no evidence that the breakers have been tampered with. The breakers have been tested for and are used in an application where overcurrent circuit coordination is needed. The breakers have been shown to meet that function. There is-no evidence that the MCCBs are more likely to fail than any other breaker. However, the rest of this analysis looks at what would happen if the breakers did fail.

Failure of the breaker will not affect plant safety. Any breaker

' failure will not impair the ability to bring the plant to a safe shutdown condition. In fact, there could be a simultaneous failure of all the breakers and both units could be brought to a safe shutdown condition. In some cases there may be a loss of redundancy; however, it would be detected and corrected during the first 7 steps of the emergency procedures. These are immediate, memorized actions.

There is no new mechanism for brecker failure. Any circuit breaker in the plant can fail as described in this report. In fact, under fault conditions it is impossible to determine with properly operating breakers if the breaker closest to the fault will open or the next breaker upstream will open. Thus, the conditions described in this report, loss of a single load or loss of an entire MCC apply to all molded case circuit breakers.

The circuit breakers in auestion do not create the possibility for an accident or malfunctio'n of a different type than evaluated previously in the USAR or any subsequent commitments.

They do not increase the probability of occurrence of an accident or malfunction of equipment important to safety previously analyzed in the USAR or subsequent commitments.

l -- WHY USED BREAKERS WERE INSTALLED ,

The electrical configuration of Prairie Island 480 Volt Motor Control Center (MCC) S'y stem has several MCC's fed from other MCC's. With this configuration, coordination between the source

!~

l and load circuit breakers is a closely balanced process.

The plant electrical design for MCC's was made to include subfed MCC's approximately 20 years ago when the plant Architect and Engineer consultant found that the number of components requiring a 480 volt MCC source. could not be supplied from existing MCC's, and no additional 480 volt bus feeder breakers were available.

The A&E concluded that on such a subfed MCC, the loads had closely related functions so the loss of any one load would I

effectively. cause the -loss of all the loads on that subfed MCC; thus protection device coordination between load and source devices was not required. Subsequently, Appendix R made it necessary to reconsider this design decision.

In the specific cases, interference between the characteristics of the two devices, source and load circuit breakers, prevented proper protective device coordination. This was first determined in the Electrical System Coordination Study performed by Impell 1 1  !

Corp. , issued in February 1987, and was a finding in the PI hk Appendix R audit of March 1987.

See Figures 1 to 6 IBM

_ _ _ _ _ _ _ _ _ _ _ _ _ _ . _ _ _ _ _ _ _ _ _ _ _ _ _ J

.l -

.$ggg y > J Pcga=6' .

t

.There are two specific coordination issues.

The first is coordination between a GE 50 ampere THED circuit breaker and a 200 ampere GE THFK circuit breaker. 'In this c'ase, the transition between the thermal magnetic (timeover current) and magnetic instanteous (short circuit) trip ,

characteristic'of the 50 ampere circuit breaker overlapped the transition section of the 200 ampere circuit breaker.

Proper coordination could not be determined in this overlap region.

The second is coordination between the GE THED 50 ampere-circuit breaker and the 100 ampere GE THED circuit breaker.

In this case, a portion of the thermal magnetic trip characteristic of the 50 amp breaker intersected the thermal' magnetic. characteristic of the 100 amp circuit breaker.

t Again, proper coordination of the two devices could not be effected.

Panel 136 coordination was not considered a safety concern during the Appendix R audit because the only significant load, the fuel oil transfer pump for the engine driven cooling water pump, supplies an 8 hour9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> day tank, which allows replacement of the panel 136 source device. The changing of circuit breaker type from THED to THEF did improve coordination. -

IBM

4

^ 55 AD Pcg3 7 i f The root cause for the,se coordination difficulties is the design of the protection curve characteristics of the THED circuit

~

breaker. The THED circuit breaker characteristic has a wide tolerance on both the thermal magnetic trip region and the transition region. This tolerance is so large that the largest size THED circuit breaker that can be coordinated with the 200 amp THFK is a 35 ampere THED, and the largest THED that can be coordinated with a 100 amp THED is a 15 ampere device.

The GE THEF circuit breaker, also supplied with our safeguards MCC's, has a much tighter tolerance on the thermal magnetic and transition portions of its characteristic curve and, by computer analysis, it was found that the 50 ampere size could be coordinated with both the 200 ampere THFK and the 100 ampere THED.

We found that we had no 50 ampere THEF circuit breakers available as spares at either Prairie Island or at Monticello, and that we could not procure new circuit breakers from GE because it had been discontinued in 1970. We, therefore, attempted to find spare or used THEF 50 circuit breakers with the aid of Lakeland Engineering.

Lakeland contacted General Electric.

l l General Electric then located " Bud Furgeson's" in California as a source for the 50 ampere THEF circuit breakers. These were used l breakers. A purchase order with Lakeland was then written to buy these circuit breakers commercial grade, used.

Upon receipt, these. circuit breakers were tested with existing.

plant procedures to verify conformance to . published thermal overcurrent characteristic curves. The circuit breakers were again. tested when the MCC cells were assembled to replace the' existing 50 amp THED cells. These tests were based on NEMA ABl.

The circuit breakers were visually inspected for apparentLdamage.

They were then mechanically cycled to verify the contact opening and closure. They were next tested at 300% of rated current to verify tripping within the manufacturer's published trip curves, and then mechanically cycled again.

In our July 1988 Appendix R inspection, the protection-coordination issues were resolved to the satisfaction of the inspectors, posing no safety problems. The THEF breakers installed satisfy the circuit coordination requirement of Appendix R.

GENERAL ANALYSIS

.In the event of an accident and 'a failure of one of the breakers '

in question, the plant can be brought to a safe shutdown /cooldown condition. This is based on the following paragraphs. . There it is. stated that only a single train of any' engineered safety system is needed. It also says t' hat a breaker failure.will affect-only a single safeguards train.

There are many mechanisms that can cause a breaker to' fail. .This evaluation-does not examine how a breaker fails, but looks at the effects of a failed breaker. There are basically two effects from a failed breaker:

1) It opens prematurely (no electrical fault downstream of breaker)

2) It opens late or not at all (fault downstream of breaker or it is the source of the fault)

If it opens prematurely, the individual load is lost. If it is delayed, it is assumed that the upstream breaker is actuated. This causes the entire MCC to be de-energized.

If the fault is located internal to the breaker, then the effect is the same as the case where the fault is downstream of the breaker and the breaker does not open on a fault.

l The breakers in. question are used in seven safety related applications

-(see Figures 7 to 13).

- 11,12, 21 and 22 battery chargers

' - 12 and 21 main feedwater motor operated isolation valve

- AC distribution panel 136 This evaluation will examine how the two failure modes . affect each load and how 'that affects plant operability and safety. Before a detailed analysis starts, it is very clear that either failure mode of any of the breakers will not impair the ability to safety shutdown the plant, This. statement is based on conclusions from the Updated Safety Analysis Report (USAR) and plant design philosophy. Attachments 1 and 2 are excerpts from the USAR. The USAR points out that the. safeguards system and electrical systems are redundant. All safety systems are designed such that a single train of the system can meet the engineered safety features of the plant. For example, see Attachment 3 which discusses losing one train of the safety injection system (SI).

Attachment 4 discusses the philosophy used when designing subfed MCC's; the seven loads that use the THEF breakers in question are on subfed MCC's. Subfed MCC's have only functionally related loads. What this means is, if one load or the entire MCC is lost, IBM

<Pago 11

' SW 362 ,1 i

l-i only a single train of an engineered safeguard system would be affected. A premature opening of the breaker will cause an individual load to be ' lost. A~ delayed breaker opening (in the event of an electrical. fault) will cause the entire subfed MCC to be lost. -Therefore, because a breaker failure will affect only a single safeguard train and'the other train is adequate to bring the plant to a safe shutdown condition. The breakers in question do not affect the safe shutdown of the plant.

Based upon our external inspection of the subject MCCB's, which concluded.that there was no evidence of tampering, we find no reason to believe that the probabiluy of internal shorting of the breaker is any greater 'than for any other breaker installed.

Therefore, the single failure assumptions of the safety analysis report are unaffected.

l During normal operation the problem is corrected.by repairing-the breaker. The control room operators would' contact station electricians. -After determining that there is no fault the electrician would. replace the breaker. The breaker-could be replaced and tested within 1 hours. Ltis is well within the battery life of 70. hours.

In the unlikely event that the breaker could not be repaired immediately, DC loads can be shed. . Plant operating procedure-C20.9 gives instructions on extending the battery-life by-shedding and transferring certain loads to. alternate sources. l This is done with the intent of maintaining the plant on line.

What Happens MCC 1AC1'will become_deenergized if the supply to #11 battery charger fails to open under a fault condition (see Figure 7).

The following will occur:

- Inverter 17, event monitoring power supply, will transfer to its DC source (battery #11).

- Inverter 11, white instrument bus power supply, will transfer to its DC source (battery #11).

- Inverter 13, blue instrument bus power supply, will transfer to its DC source (battery #11).

- Panel 117 will be deenergized. Panel 117 is'a backup power supply to some primary side control systems. It is the only power supply to some secondary control systems. The net effect of losing panel 117 is that the plant can continue to run in a safe manner; however, the l plant's efficiency will be reduced due to loss of power to equipment such as feedwater heater level control.

(see attachmen' 7 - Load Lists).

How Discovered The control room operators will be alerted to the problem by a series of alarms. The most obvious will be:

- #11 Battery Charger AC Failure

- #17 Inverter Bypassed

- #11 Inverter Bypassed

- #13 Inverter Bypassed Normal Operation As stated earlier, the plant will continue to operate if MCC 1ACl is lost. However, the secondary side efficiency will be reduced due to control problems. Also, some secondary 1 1

1 III Feedwater Isolation to #12 Steam Generator (MV-32024 Bkr #123-36) [#22 Steam Generator-MV-32029 Bkr #223-37]

The purpose of #12 [#22] Steam Generator feedwater isolation valve is to provide one train of containment isolation.

It receives an auto close signal from the containment isolation (CI) Train B circuitry. Back up containment isolation is provided by the check valve F-8-2 (2F-8-2) located in containment. (See Figure 14)

L III.A. Premature Breaker Opening What Happens*

A CI signal causes MV-32024 to get a close signal, which results.in the br'eaker opening. (Attempting to open MV-32024 when it is closed is not considered here s

because the valve is already in the safe condition).

A CI occurs as a results of a safety injection (SI) or a manuel initiation.  ;

How Discovered f

The Control Room operators would be alerted to MV-32024 i i

(MV-32029) not being closed because its light on the l i

Containment Isolation panel would not be lit. Also, the Emergency Response Computer System (ERCS) would alert the operator. The operator would then look at the valve's indicating lights on the control board. Becauce both the open and closed light would be out the operator would know the breaker had tripped.

I Normal Operation This valve is not operated during normal operation; therefore there is no impact.

' Accident' Conditions

'One of the initial memorized actions-following a SI is

.to verify _that all containment isolation valves are i closed. Using the instrumentation discussed above the Control Room operator would direct the-Auxiliary Building operator to manuall'y close MV-32024 (MV-32029).- Until MV-32024 (MV-32029) is closed, isolation is provided by the check valve F-8-2 (2F-8-2). Either the check valve or the motor valve by themselves provide adequate containment isolation (USAR Vol 2 Section 5.2)'.

III.B. Breaker Not Opening What Happens-Assuming there is an electrical fault downstream of 123-36 (223-37) a CI signal ~will deenergize MCC lKA2 (MCC 2KA2). This is because breaker'123-36 fails to open under a fault condition (See Figure 11). Attachment'8 is a load list of what loads are deenergized.

How Discovered

/

This will on'ly occur as a result of an SI/CI. As the Control Room Operator goes th, rough the iEitial action on an SI, they will discover some "SI Active" lights not lit and some " Containment Isolation" lights not l'it. They.

will also notice no control board light indication.for the affected valves.

Normal Operation MV-32024 (MV-32029) is not operated during normal operation.

e Accident Conditions The operator will immediately be alerted to the "SI Active" and " Containment Isolation" lights not being lit. All the valves affected are Train B valves. Therefore, Train A valves are providing the intended safety function. Part of the operators' immediate initial actions will be to take local manual control of the valves and place them in the required position. For this case, the following will need to be done manually:

Failure Evaluation

~

The purpose of th'is section is to described the. thought ,

. process used in evaluating the MCCB's.

First it was assumed that th'e breakers fail. The-breaker fails differently depending on if there is an' electrical fault or not. For' example, if there is no fault downstream of the breaker, the breaker opens. This causes'the load supplied by the breaker to be lost. If there is a fault downstream,.the breaker doesn't open. As a result, the next breaker upstream opens, clearing the fault. However, this will cause an MCC to become de-energized, th..refore losing all functions powered from it.

Different examples of plant failures had to be looked at assuming the breakers in question =would not operate correctly. For example if the following is assumed:

I

- A fault removes Train A safeguards equipment. j l

1

- Train B safeguards equipment functions _,

L i

normally except for the breakers in question. 1 l

IBM

,; . .'Pega:27 What Would Happen?

The results are:."

- 11 and 12 battery charger would fail, but the batteries would back them'up.

The Train B feedwater containment isolation valve would not close, but it is backed up by a check valve.

- Therefore, the plant can be brought to a safe.

shutdown condition, Another scenario is to assume there is a fault downstream of the breaker for MV-32024 (123-36 see Figure 11). Breaker 123-36 fails to open. Breaker 123-15 opens, clearing the fault and de-energizing MCC 1KA2. As discussed in the evaluation, a number of Train B safeguard valves don't actuate, but they are backed up by the Train A safeguard valves.

IBM

$$ y.f L 4

- Pcga428 .

This is an extremely conservative approach. First, assuming all.the breakers in_ question open up under normal.loadsLis very conservative.' All loads have operated with the breakers in question installed. This is part of our normal testing procedure before a breaker is. declared operable. - ,

Second, all of the breakers 'in question have been. tested to ensure they coordinate with the upstream breaker. Thus, assuming the upstream breaker must open to clear a fault is also very conservative.

. PRAIRIE ISLAND SECTION 8 l PLANI ELECTRICAL SYSTEMS 8.1 fUMMARY Each main generator feeds electrical power at 20 KV through its isolated pharm bus to the associated Main Transformer. The power requirements for station and unit auxiliaries are supplied by an Auxiliary Transformer (Unit Auxiliary Transformer) connected to the isolated phase bus, following practices that have been highly satisfactory for fossil-fueled and other nuclear units.

Auxilf.ary power for startup, shutdown and normal backup is supplied from auxiliary transformers designated IR and 2R. Transformer 1R is the normal backup source for Unit 1 and is connected ' to the 161kV external power system.

Transformer 2R is the normal backup source for Unit 2 and is connected to the 345kV external power system (via a 345-35kV substation transformer). Bus ties are provided to allow crossfeeding should one transformer be out of service.

Redundant offsite power sources are provided of sufficient capacity to supply 82-056 all critical loads for either or both units. Each Safeguards bus has a preferred and alternate oefsite source consisting of a startup transformer or a cooling tower substation transformer. The cooling tower substation sources are not large enough to also serve as a redundant startup source. Emergency backup power, to ensure continuity of supply for critical loads, is supplied from two onsite, quick-start d1esel genarators.

The function of the Auxiliary Electrical Systee is to provide reliable power to those auxiliaries required during any nor=al or emergency mode of plant operation.

l l The design of the system is such that sufficient . independence or isolation between the various sources of electrical power is provided in order to guard against concurrent loss of all auxiliary power.

All electrical systems and components vital to plant safety, including the l . diesel generators, are designed as Class I systems so that their integrity is not impaired by the Design Basis Earthquake, vind storms floods, or disturbances to the external electrical system. Power, control and instrument cabling, motors and other electrical equipment required for operation of the I

eng;ineered safety features are suitably protected against the effects of either a Design Basis Accident, or of severe external environmental phenomena in order to assure a high degree of confidence in the operability of such components in the event their nie is required.

Independent alternate power systems are provided with adequate capacity and testability to supply the required engineered safety features and protection systems.

The plant is supplied with nor=al, standby, and emergency power sources as i

follows:

1

a. The main source of auxiliary power during operation of either Unit is the Unit's generator. Power is supplied via the Unit Auxiliary Transformer that is connected to the main leads of the generator.

8.1-1 RIV 1 12/82

,t l

c l

l PRAIRIE ISLAND .

b. Standby power required during startup, shutdown, and after reactor trip of either. Unit is supplied from the Northern States Power- j Company's 161-KV and 345-KV transmission systems.

j l

c. ' Two diesel generator sets common to both Units. are connected to the i engineered safety features buses cf both Units-to supply emergency shutdown power in the event of loss of all other a-c auxillary power.

d.- Emergency power supply of vita'l instruments, for control and for emergency lighting for each Unit is supplied from two 125V d-c

, station batteries.

The djesel' generators are connected to the separate 4160-volt auxiliary-system buses of both Units. Each set is started automatically on a safety injection signal from.elther Unit or'upon the occurrence of under-voltage on either,of its corresponding L160-volt auxiliary buses. Each diesel has adequate.

capacity to supply the engineered safety features for the Design Basis Accident in one Unit, and to allow the second Unit to be placed in a safe shutdown condition in the event of loss of outside electrical power. No accident is assumed in the second Unit.

e. Long-term cooling. After any calculated successful initial operation of the ECCS the calculated core temperature shall be maintained at an acceptably low value and d="*y heat shall be removed for the extended period of time rer,. ed by the long-lived radioactivity remaining in the core.

For any rupture of a Steam pipe and the associated uncontrolled heat removal )

from the core, the Safety injection System adds shutdown reactively so that >

l with a stuck rod, no of f site power ano minimum engineered saf ety f eatures.

there is nd consequential damage to the Reactor Coolant System and the core  ;

remains in place and intact.

I f Redundacy and segregation of instrumentation and components are incorporated to assure that postulated malfunctions will not impair.the ability of the I system to meet the design criteria. The system is effective in the event of . i loss of normal plant auxiliary power coincident with the loss of coolant, and can accommodate the failure of any single component or instrument channel,to i respond actively in the system. During the recirculation phase of a loss-of- }'

coolant accident, the system can accommodate a loss of any part of the flow path since back up alternative flow path capability is provided.

The ability of the Safety injection System to meet its design criteria is l presented in Section 6.2.3. The analysis of the accidents is presented in I

Section IL.

6.2.1.2 Inseection of Emereenev Core teoline System Design provisions are made to facilitate access to the critical parts of the reactor vessel internals. Injection nozzles, pipes, valves and safety injection pumps for visual or boroscopic inspection for erosion, corrosion and vibration wear evidence, and for non-destructive inspection where such techniques are desirable and appropriate.

6.2.1.3 Testine of Emereenev Core Cooline Svstem Comconents The design provided for periodic testing of active components of the Safety injection System for operability and functional performance'.

j Power sources are arranged to permi, individual actuation of each active l

component of the Safety injection system.

The safety injection pumps can be tested periodically during plant operation using the minimum flow recirculation lines provided. The residual heat removal pumps are used every time the residual heat removal loop is put into operation. All remote operated valves can be exercised and actuation circuits can be tested during routine plant operation.

PRAIRIE ISLAND l

l 6.2.3.5 Single Failure Analvsis A single active failure analysis is presented in Table 6.2-8a. All credible active system failures are considered. The analysis of the loss-of-coolant 1 accident presented in Section 14 is consistent with the single failure l analysis.

It is based on the worst single failure (generally a pump failure) in both the j safety injection and residual heat removal pumping systems. The analysis f shows that the f ailure of any single active component will not prevent fulfilling the design function. .

In addition, an alternative flow path is available to maintain core cooling if any part of the recirculation flow path becomes unavailable. This is evaluated in Table 6.2-8b. This evaluation includes all the piping in each recirculation path. A rupture anywhere in a flow path associated with any of these components requires the operator to isolate the entire path and use the alternate flow path, which action can be accomplished from the control room.

A ruptured flow path would be detected and identified by flow indication.

Rupture of a residual heat removal loop external to the Shield Building would be detected and identified (and therefore adequately located) by sump water level and by airborne activity indications associated specifically with that loop.

The su=p pumps for the RER pits are each powered by one of the rvo diesel generators.

Failure analyses of the component cooling and cooling water system under loss-of-coolant accident conditions are described in Section 10.4.2 and 10.4.1 respectively.

A single failure analysis of the Emergency Core Cooling System (ECCS) and its supporting subsystems is included in a report titled "ECCS Actuation System" submitted to the NRC dated December 22, 1976. Additional information was submitted by letters dated July 17 August 5 and September 10, 1981.

The analysis was reviewed and accepted by the NRC per Reference 4. The analysis demonstrates that the ECCS and supporting subsystems meet the single f ailure criterion as defined in IEEE STD 270-1971. The NRC requested a Technical Specification change to cover the control of evo valvas (SI-14-1 and SI-14-2, see Figure 6.2-2). Either of these valves being closed would prevent the "S" SI pu=p from inj ecting into the cold legs. Following plant 82-1.l review, the NRC was inf ormed that these valves are already cavered in the Technical Specifications under a general specification dealing with valves which could affect an injection path, o

ATTACEMENT 3

1 TELEPHONE MEMORANDUM DATE 7/12/88 1

BY E. Burke i WITH R. Peterson, E. Haupt Fluor-Daniel I SUBJECT Prairie Island Design Basis For Subfed MCC's l

. i i

I spoke with Bob and Ed to find out what the original design basis was for subfeeding MCC's at Prairie Island.

They told me that the original reason was that the number of .

electrical leads increased beyond.the capacity for the j

existing MCC's to hold the required number of cells, and new MCC's could not be fed from the existing 480 volt switchgear because there were not enough circuit breakers avai?.able to supply the number of new MCC's required.

Each subfed MCC was carefully laid out so that each would have functionally'related loads connected to it and that a loss of any load on the MCC would. effectively disable all the ,

loads on that MCC. Therefore,' coordination of protective  !

devices on the subfed MCC with the source device or. the upstream MCC was not required.

an estimate of the time to discharge the battery to -l 1.81 V/ cell under Blackout conditions. The load study portion 1' of the report was provided to NSP as a data set which can be run on Lotus 1-2-3. L The new proposed revision of ECA 0.0 specifies that the P250 computer and the Containment-area Emergency Lighting shall be deeneergized under Blackout conditions to extend battery j life. I conservatively estimated the benefit of eliminating  ;

the Containment Emergency Lighting at 40 A. At this time a reasonable number for calculating the power consumed by the P-250 is not available, so I ran the data set estimating a reduction in load on #16 Inverter at 40/ 60/ 80/ and 100 A.

The total load used in the study for Inverter #16 is 168 A.

SAkul EVALUATION REPORT (Revised)

The existing Prairie Island Class 1E Batteries per the USAR, Section 8.5.2, were j sined to carry expec:ed shutdown loads followeg a plant trip and a loss of AC battery charging power for a period of one hour crithout the battery terminal voltsge falling below 105 volts. This was based on the original plent lead-antimony bacteries which had a 960 Amphour capacity at the 8 hour9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> discharge race.

This Design Change 82N505, Part III, originally provided that the 2,11owing major non-safeguard loads be removed from the present Class 1E Batteries:

Emergency Lighting Panel EMI-5 From 12 Battery Electric Shop DC Power From 12 Battery 21 Emergency Turbir- Oil Pump From 21 Battery E=ergency Lighting Panel EM2-4 From 22 Battery The Fluor Electrical System Load Study - Phase II, transmi::ed by FN-4659, Augus: 6, 1982, (Attachment 2 of this Design Change Package) indicates that with the above loads removed, the Class II Batteries would provide 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> under the ,

above USAR scenario without the terminal voltage fallin; below 105 volts.

However, some of the battery load assu=ptions used in that study are

(, questionable. ,

In actuality, as of this date, the original 996 Amphour 11, 12, 21, and 22 Batteries have been replaced with nominal 1800 Amphour batteries which now provide more than one hour for the plant trip and loss of AC battery charging power (Loss of all AC scanario). The following is an updated analysis of bactery capacity for the safeguard bacteries. The scope of DC 82N505 Par: III was revised due to Q-List problems such that the Emergency Lighting Panels EMI-5 and EM2-4 were not removed from Batteries 12 and 22. The f.illowing analysis also includes that new 17, 18, 27, and 28 Inverters which vare added by Projec: 80Y124 (RVLIS).

' Battery Operating Capacity for Loss-of-ell AC in Amps per positive plata is based on the following calculation: (From IEEE 435-1983)

2actory Operating Times are as follows:

70 Minutes Battery #12 Battery #21 4 Hours Battery #22 95 Minutes .

These numbers are conservative since all inverters were assumed to be' at maximum L load which :is not really the case.

The new plant non-safeguard batteries (31 & 42), which were installed under Part III of DC 82N505, supply the major plant non-safeguard loads. The present' loads on' these batteries and associated distribution panels ar's as shown in 1

Appendia II.

A calculation w'as cons to determine the Design Operating Time with the present leads based on Battery 31 as the worst case and assuming no AC charging:

Based on the calculation and the GNE Discharge Characteristic Table, 31 and 42 Batteries, would be adequate for approximately 7i hours based on final voltage  :

of 1.75 volts / cell (60 cells) - 105 volts, which is the same criteria used for

!' the safeguard batteries. Using a final voltage criteria of 108.6 volts (120 nominal, 10%), which is 1.81 volts / cell, the operating time would be 7 hours8.101852e-5 days <br />0.00194 hours <br />1.157407e-5 weeks <br />2.6635e-6 months <br />.

.In order to determine' an ultimate capacity of these batteries for addition of

~ future loads, another calculation was done:

Assuming the same starting loa' d and random load as above, determine the.

maximum continuous (steady-state) load such that the batteries would last for 2 hour2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br />s: ,

' Based on the 108.6 ' volts final voltage criteria (1.81 volts / cell), the

.naximum continuous load is 604 Kap.

For the 105 volts final voltage criteria (1.75. volts / cell) the maximum continuous load is 669 Amp.

Figures and tables referenced by Section 8.5.2 of the USAR must be changed .to . ,

reflect non-safeguard loads removed from the safeguard batteries. Specific documents are listed in other parts of the Design Change Package.

Based on the above discussion, it is concluded that:

~

'A. The change is not in conflict with the k'echnical Specification.

3. 'The change does not include an unreviewed safety question.

C. The changedoes involve a system described in the FSAR.

D.# The change 'does not create a possibility of an accident nor equipment *

., malfunction which is different from those previously analyzed in the

'FSAR or amendments.

E. The change also does not increase the possibility of occurrence nor the consequences of an accident or equipment malfunction wh!:h has .]

been evaluated in the TSAR or amendments. . j

. 1

'F . The change does not reduce the margins of safety as defined in the basis for Technical specifications of this plar G. Based on the above, the change does not adversely affect the safety of the plant nor the health and safety of the public. T l
