l D e l l ENCLOSURE 1

~ --l-.- ? 1. The onsite distribution system for each unit at Salem is arranged so that two vital buses are connected to one station power transformer and the third is connected to the other station power transformer (FSAR figure 8.3.1). The in-feed breakers f or each vital bus f rom the eco station power transformers are electrically interlocked to prevent paralleling both sources through a vital bus. The breakers also provide the means for transfer-ring between sources in the event of an interruption of power from one source. Undervoltage protection f or each vital bus will be pro-vided by two protective relay groups. One group is de-signed to protect the vital buses if bus supply voltage f alls below 70% of its rated value. This group is al-ready installed and operable. The other group will be designed to proter', the vital buses if bus supply volt-age falls below 91% of its rated vclue. Each undervoltage protection. group is/will be comprised of two sets of relays: A set for undervoltage transfer, and A set f or generating " Blackout" signals. The 91% group will be comprised of adjustable time delay relays. The protective relays will be connected to the electrical system in the same manner and location as the present undervoltage protection. The new design essen-tially duplicates the present protective scheme in all regards (Attachment A) with the following exception. The 91% relays will be equipped with an administrative 1y controlled lockout which will allow the control room op-erator to disarm the system ducing the start of any re-actor coolant pump. This feature is required to fore-stall any unnecessary undervoltage signals due to the voltage transient caused by a reactor coolant pump start. The lack of this manual lockout feature would require that an extended time delay (30 seconds) be used to actuate the 91% relays. The system will be armed by the control room operator upon completion of any RCP start, and will remain armed under all conditions other than a RCP start. The disarming and rearming of the system will become an integral part of the RCP starting HK19/2

procedures used at Salem and an alarm will be provided for the disarmed condition. In addition to manual re-arming, a timer will be provided to automatically rearm the system in the event the control room operator neg-1ects to do so after a RCP has been started. The time delay of the 91% undervoltage t_ransfer relays will be 10.5 seconds when the output of the station power transformers is below 91% of its rated value (Figure 1). The time delay of the 91% bus " blackout" relays will be 13 seconds when the voltage on the affected bus (or buses) is below 91% of rated value (Figure 1). In the event the supply voltage to a 4 KV vital bus or buses f alls below 91% of its rated voltage, the af f ected bus or buses will be automatically transferred to the alternate source by the action of the vital bus transfer relay (XET-230, Fig. 1) and the 91% transfer relays af-ter a 10.5 second time delay.' The following conditions must be met before a bus trans-fer may be accomplished at either low-voltage condition: a. The bus differential or overload relays have not

operated, b.

Voltage on the affected bus or buses is below 35% (this permissive prevents transfer with excessive out-of-phase residual bus voltage). c. The in-feed breaker of the normal supply is opened. d. The related diesel-generator circuit breaker is open. e. The alternate source voltage is above 91%. f. The SEC (Safeguards Equipment Control) bus under-voltage (blackout) relays have not operated. For both groups (70% and 91%), the undervoltage and vital bus (XET-230) transfer relays allow the affected bus or buses to be transferred to the remaining station power transformer before the bus blackout relays are tripped. HK19/3 l' l

s . 1 If the supply voltage to the vital buses falls below 70% of rated voltage and a transfer is not accomplished, the 70% blackout relays will provide a signal to start the diesel-generators. If the supply voltage to the vital i buses f alls below 91% of rated voltage and a transfer is not accomplished, the 91% bus blackout relays will pro-l vide a signal to start the diesel-generators. Undervoltage signals generated by either set of blackout relays will be combined (through the use of buffer re-lays) in a 2/3 logic matrix per bus to develop a black-out loading signal for that bus. The buffer relays will be used on each vital bus undervoltage sensor to supply independent signals to each SEC unit to maintain inde-pendence amang the three buses. 3 If the output voltage of a station power transformer supplying one vital bus falls to 70% of its rated value and the transfer mechanism fails, the 70% blackout relay for that bus will generate a signal which results in a 1/3 condition at each SEC controller. The Salem design is such that a loss of one vital bus is tolerable for all normal operating conditions; therefore, no automatic equipment actuation will take place for this condition. This design will also apply to the new 91% protective relays. For a postulated LOCA, this criterion will not apply. A postulated LOCA concurrent with an undervolt-age condition on one vital bus is discussed in the re-sponse to question 5. 2. The proposed design will employ test switches which can be used in con] unction with any external equipment (var-iable power supply, etc.) necessary for proper calibra-tion and testing. Technical specifications similar to those for the exist-ing undervoltage protection will be generated upon the Staff's approval of the proposed design. 3. Since this design is a duplicate of the present under-voltage protection system (except for the administrative controls), it will meet the necessary criteria for pro-tection and control of Class 1E equipment (IEEE 279-1971). HK19/4

j ~ " ~~ ^ - ^ .: =., l e i _4 4. If a LOCA concurrent with a voltage degradation which reduces the output of both station power transformers to between 90% and 70% of rateo voltage is postulated, the SEC system will react only to the LOCA while the 91% transfer relays are timing out. The time for the relays to actuate will be 10.5 seconds. A While the relays are timing out, the SEC system will perform the following functions: a. Start the diesel-generator units. b. Lockout manual control of equipment circuit breakers until the required loads are connected to the vital buses. c. Connect all required accident loads. The diesel-generators are started automatically so as to be available in the event the,y are subsequently re-quired. They are not automatically connected to the vi-tal buses. The ability of the safeguards motors to start and carry their designated loads under degraded voltage conditions is described in Attachment B. The safeguards motors are capable of withstanding degraded voltage conditions for the times under consideration without suffering any thermal damage. When the 91% transfer relays time out (10.5 seconds), the transfer will not take place because the station power transformer potential relays will not generate a pe rmis sive. Therefore, the 91% blackout relays will be allowed to time out (in an additional 2.5 seconds), and a blackout signal will be generated. When the blackout signal is generated, the SEC will automatically shift modes from that for a LOCA (Mode I) to that for a LOCA plus blackout (Mode III). The shift of modes will re-quire less time than the recognition and action required to combat only a blackout due to the " ready' status of the diesel-generators. HKl9/5

e d . The above mentioned sequence of operations will take place within the required time limits to successfully mitigate the consequences of a LOCA. A delay time of 15 seconds between the occurrence of the incident and the application of power to the first sequenced safeguards pumps was assumed in the original LOCA analysis. Although regarded as extremely unlikely, it may be pos-tulated that one station power transformer may suf fer a voltage degradation which reduces its output voltage to between 90% and 70% of its rated value while the output of the remaining station power transformer is reduced to just above 91% of rated voltage. Under these condi-tions, one set of 91% transfer relays will begin timing out while the other set " sees" no abnormal conditions. It may be possible to reduce the output voltage of the " normal" transformer to below 91% of its rated value af-ter the transfer from the affected transformer takes place. Also, the output voltage of the initially af-fected transformer may rise above 91% of its rated value due to its partial unloading. These voltage changes will not amount to more than 3% for each transformer. Consequently, the 91% transfer relays for the alternate transformer will begin timing out and would effect a subsequent transfer at the end of an additional 10.5 seconds. These conditions would result in a continual flip-flop condition causing intermittent power interrup-tions on the vital buses. This action will be prevented by the installation of 91% blackout relays which have a 95% reset setting. The 91% blackout relays began timing out at the same time as the 91% transfer relays on the initially affected trans-former. Since their time delay will be 2.5 seconds longer than that of the transfer relays, and if the transfer does not successfully raise the bus voltage above 95%, the bus relays will initiate separation of the bus from both transf ormers. The reset setting of 95% on the transfer relays will also ensure that the buses do not continually transfer from one source to the other. The interlocks and permissives utilized in the transfer of buses are described in Item 1. HK19/6

5. In the event a LOCA occurs concurrent with a voltage level on one vital bus below 90% and above 70% of rated voltage, the SEC response will be the same as that ex-plained in Item 4 while the 91% transfer relays are tim-ing out. Once the relays have timed out, a transfer to the alternate source will take place. If che transfer mechanism fails, a blackout signal will be generated for the affected bus and the SEC will auto-matica11y shift from a Mode I (LOCA) to a Mode IV (LOCA plus one vital bus undervoltage) condition, whereby only the affected bus is connected to its diesel-generator. The other two buses will remain connected to offsite power. If a LOCA occurs concurrent with a degraded voltage con-dition on two of the three vital buses which reduces the bus voltages to between 90% and 70% of rated voltage, the SEC will react as explained in Item 4 while the 91% transfer relays are timing out. Once the relays time out, the buses will be transferred to their alternate source. If the transfer mechanism fails, a blackout signal will be generated and the SEC will automatically shift from a Mode I (LOCA) to a Mode III (LOCA plus blackout) condi-tion, whereby all three vital buses will be shifted to diesel-generator power. For both postulated conditions, the safeguards motors on the af fected bus or buses will be subjected to degraded voltage conditions for no more than 13 seconds. Their ability to start and maintain operation (or to withstand a postulated voltage degradation which prevents starting) during the period prior to bus transfer, and the accepta-bility of the time delays involved are explained in Item 4. 6. The characteristics of AC contactors and associated control fuses are described in Attachment B. 7 With regard to Staff's suggestions of utilizing only bus blackout relays in the proposed design (no attempted transfer), the following scenario is presented. HKl9/7 l l 1

e The existing diesel starting and sequence loading logic is located in the Safeguards Equipment Control (SEC) sys-tem associated with each bus. The plant design is predi-cated on each SEC performing the master decision making and resultant actions associated with bus loading. To make use of this existing logic with the design sug-gested, would require paralleling the existing bus under-voltage inputs and the proposed secondary bus under-voltage relays. Assuming an initial system configuration of two buses being supplied from one station power transformer (as-sume #11) and the remaining bus powered by #12 SPT, a degraded voltage condition on #11 SPT side, coupled with a single failure within the bus voltage monitoring logic, could result in the following condition: Bus "A" operating with degraded voltage due to failure in monitoring logic. Bus "B" operating with degraded voltage due to lack of required coincident logic in SEC (failure cascaded from failure in Bus "A" circuits). Bus "C" operating at normal voltage supplied from #12 SPT. The above scenario assumed that no condition exists which would generate a Safety Injection (SI) signal. If an SI signal were to exist during this occurrence, the following system configuration would result: Bus "A" could attempt to block load all ESF loads during a degraded voltage situation. This would most likely result in a further bus voltage degradation to below 70% and cause the diesel to start and commence sequential loading via the SEC. Bus "B" would follow the sequence of events described in Item 5 for a postulated LOCA concurrent with a voltage degradation on one vital bus. Bus "C" would " block load" the ESF loads on the normal supply from the #12 SPT. The sequence described for the case of "No SI Signal" is unacceptable. The proposed design which includes an at-tempted transfer, precludes that sequence of events and l ensures that at least two buses are capable of supplying l the needed equipment. l l l l HK19/8

I and 2 electric power system in accordance with NRC letter, Adequacy of Station Electric Distribution System Voltages dated August 8, 1979 and its enclosures. The analysis demonstrates that the offsite power system and the onsite distribution system is of sufficient capacity and capa-bility to automatically start as well as operate all safety loads within their voltage ratings for all anticipated transients and accidents, Satisfactory results were obtained as a result of the original design considerations. The, Salem Generating Station was designed such that the resulting voltage profile was within component voltage limitations, being +5% of transformer secondary voltage and -10% of motor nameplate voltage under steady-state conditions. The system was also designed such that t.he inrush current associ-ated with the start of a 6000 horsepower, 4.0 kV motor would not cause the bus voltages to drop below 80%. All motors are de-signed to accelerate their driven equipment with at least 80t motor nameplate voltage applied to its terminals. This was accomplished by optimum selection of transformer impedances, incorporation of no-load taps on all power and unit substation transformers, and a + lot automatic load tap changer on all the 13.8/4.16 station pcGer transformers. All motor starters have a guaranteed drop out voltage of 701. All starters were bought with 300 VA control power transformers, regardless of Mr.MA size, to minimize voltage drop at the contactor coil.

v.' EHCLOSUPE 1 BACKGROUND THFORKATION ON AND EVENT The event that occurred at the Arkansas Huclear One station on September 16, 1978, brought into question the conformance of the station electric distribution system design to GOC-17 with regard to the capacity and the capability of the onsite systems. ~ Each of two units at the ANO station has a dedicated startup transformer cennected to a single shared autotransformer (common source of offsite The incident was initiated by power) from the station switchyard. Unit 1 reactor trip concurrent with trip of the unit's turbine-generator. The Unit 1 auxiliary loads were automatically transferred to Startup The power being supplied to Startup Transformer 3 (Unit Trans former 1. 2 dedicated startup transformer), which was feeding Unit 2, and being supplied to Startup Transformer 1 resulted in operation of an autotransformer overturrent relay and consequent tripping of the incoming circuit breaker-The autotransformer has the capacity to provide of the autotransformer. power for both units, but due to an error, the overcurrent relay was still set for the operation. of Unit 1 only. Loss of input power to the two Startup transformers automatically transferred the auxiliary loads for However, this trans-both units to the backup Startup Transformer, ST 2. former is designed as an alternate supply for one unit and is not designed This overload caused a to carry full auxiliary loads for both units.The event to this point voltage degradation at the safety buses. demonstrated that the design of the offsite power system to the ANO station Units 1 and 2 did not fully meet GDC-17. In the circumstances experienced at AND the failure of one of the two offsite electric power GCC-17 circuits resulted in failure of the other electric power circuit. requires, in part, that (1) electric power from the transmission network to the onsite distribution system shall be supplied by two physically independent circuits (not necessarily on separate rights of way) designed and located 50 as to minimize to the extent practical the likelihood of their simultaneous failure under operating and environmental conditions and (2) provision shall be included to minimize the probability of losing electric power from any of the remaining supplies as a result of, or coincident with, the loss of power generated by the nuclear unit, or The Ta0 did not fully the loss of.pewer from the transmission network. meet these requirements. Initially, the sequence of events on September 16, 1978 did not indicate

Powever, any problem with the electrical distribution system of Unit 1.

subsequent analysis by the licensee indicated that in the event cf a LOCA at Unit i during which time Startup Transformer No.1 would be required to provide power to both the non-safety auxiliary electrical

t 9 J 2 loads and start the safety loads a voltage degradation would result.. The safety loads might not transfer to the Unit I diesel-generators but could remain on the startup transfomer with unacceptably degraded voltage. Although there is margin in the themal capability of equipment such a situation could result in thermal damage in the safety equipmert and/or i blown fuses in control circuits for these safety loads. Either event could result in disabling these loads during a LOCA. GDC-17 requires, in part, that electric power supplies for nuclear power plants provide suf ficient capacity and capability to assure that certain limits are not exceeded in the event of anticipated operational nccurrences and that the core is cooled and containment integrity and other vital functions are maintained in the event of postulated failures. The ANO design was not capable of providing the electric poner of "sufficiert capacity and capability." t 4 e i i i

SUBJECT:

RESPONSE TO NRC LETTER ADEQUACY OF STATION ELECTRIC DISTRIBUTION SYSTEM VOLTAGES DATED AUGUST 8, 1979 We have performed the analysis on the Salem Generating Station Units Nos.1 and 2 electric power system in accordance with NRC letter, Adequacy of Station Electric Distribution System Voltages dated August 8, 1979 and its enclosures. The analysis demonstrates that the offsite power system and the onsite distribution system is of sufficient capacity and capability to automatically start as well as operate all safety loads within their voltage ratings for all anticipated transients and accidents. Satisfactory results were obtained as a result of the original The Salem Generating Station was design considerations. designed such that the resulting voltage profile was within component voltage limitations, being +5% of transformer secondary voltage and -10% of motor nameplate voltage under The system was also designed euch steady-state conditions. that the inrush current associated with the start of a 6000 horsepower, 4.0 kV motor would not cause the bus voltages to All motors are designed to accelerate their drop below 80%. driven equipment with at least 80% motor nameplate voltage applied to its terminals. This was accomplished by optimum selection of transformer impedances, incorporation of no-load and a taps on all power and unit substation transformers, 13.8/4.16 station i 10% automatic load tap changer on all theAll motor starters have a guaranteed power transformers. All starters were bought with 300 VA out voltage of 70%. control power transformers, regardless of NEMA size, to minimize voltage _ drop at the contactor coil. Further, consideration was given to cable size and length to limit voltage drop in a feeder. 2-02 2 f 1-

F. P. Librizzi Gen'l. Mgr. - Electric Production Page 2 The analysis chowed the worse sustained under-voltage condition imposed upon the distribution system occurred with a severely degraded 500 kV offsite system simultaneous with* a concurrent LOCA on Unit 2 and Unit trip on Unit 1 (or vice versa). This under-voltage condition results from the automatic transfer of the group buses from the auxiliary power transformers to the station power transformer and the automatic start of the required-vital bus loado. For this condition the lowest voltages at the 4.16 kV, 460V and 230V loads were.917,.92,3 and.91 per unit respectively. The above analysis indicates that the onsite distribution system and its components will operate.within component voltage limitations.- The motors are the limiting component under steady-state conditbns as they are designed to run continuously at.9 per unit nameplate voltage. Transient voltage drops due to the starting of motors were analyzed at each voltage level with no adverse effects. This analysis assumed the prestart voltage to be that corresponding to the degraded 500 kV system and the load in parallel with the motor being started equal to the maximum continuous rating cf the transformer to which it is connected less the running load of the motor being started. Further, the impedance of the parallel load was conservatively assumed to decrease as the square of the bus voltage to analytically compensate for the additional current drawn by induction motors upon decrease in voltage. The minimum transient voltages obtained on the 4.16 kV, 460V and 230V levels were.86, .86 and.78 per unit, 2 ~ respectively, for'a duration of approximately(5; seconds.'~ These transients are-within motor and motor sthrter design capabilities, thereby having no adverse effect on system operation. The results of this analysis were used to re-examine under-voltage protective settings and establish that no spurious separations of the safety buses from offsite power would occur. The 5 kV power cables that connect the 13.8/4.16 kV station power transformers to the group and vital buses are the load limiting component in the distribution system. The sixteen hour rating of the cable is utilized for the load tha t 'results - from the concurrent LOCA. Unit 2 and Unit trip on Unit 1. There is sufficient margin between the cable rating and the resultant load to allow for implementation of existing station procedures used during the events analyzed and thus, avoid overloading. l l'

l LOAD TABULATION PURPOSE: The purpose of the load tabulation i s to arrive at a load that reflects the greatest plant loading for use in calcu-lation of the voltage profile. RESULTS: The load profile is attached. The g reatest load results with a simultaneous LOCA on Unit 2 and unit trip on Unit 1. In addition to initiating loading of the vital buses in Unit 2, the event (s) also initiate transfer of the group bus loads to the station power transformers. The load limiting component was identified as the 5 kV power cables. Comparison of this to be load profile shows the cable to be within rating with adequate margin. Further discussion is contained in PSE&G response to NRC 8/22/79 request and may be fou.nd in Appendix I. 301 16A l O

Using actual 4 kV motor data from PSBP 140032, 111059, 112305, 112GS3, 119349, 140042, 124584, 140041, 135633, 135634, 140040 and 112698 and one lines 203001, 203062, 203061, 203002 and 203004 motor quantities, full load horsepower, efficiency and power factor were obtained to calculate motor KVA using the relationship. KVA = (llP) (.746) (pt) (ett) 2. Pump BilP (brake horsepower) was used rather than motor nameplate HP if the former was well defined. Actual running data was used to determine a conservative reactor coolant pump BHP. 3. The attached sheets entitled Motor Operational Informa-tion was used as a reference. 4. Individual load KVA was conservatively assumed to be additive. 5. The attached one line shows the switching arrangement. 6. To arrive at a conservative maximum loading it was as-sumed that No. 1 station power was carrying 4 of 6 vital buses (normal switching it would carry 3) and that the 4 kV loads were aligned to give the maximum. 301 17A 1 e

o (7 VOLTAGE PROFILE j l General Discussion The voltage profile with a given plant must be examined for both steady, sta te and transient conditions. This voltage profile is largely depended upon two variables, those being the system voltage regulation at the terminals of the plant and the plant load regulation. The steady state profile can be most readily examined by analyzing the end points. The lowest possible steady voltage will result with the lowest attainable system voltage coupled with the greatest plant load. The highest voltage possible will be with the highest attainable system voltage and the least amount of plant load. All other voltage profiles resulting from other plant loads or system conditions would lie between these two points. The re sul ta n t profiles must then fall within the component voltage limitations which will be discussed later. The grea test voltage drop resulting from transient condi-tions usually results from the start of the largest motor a t each vol tage level, coupled with the grea test plant load and the lowest system voltage. Bus transfer should also be examined. WSR:pd 202 39 6 4 0

SUMMARY

OF RESULTS 1. The g reatest sustained voltage drop results with the 500 kV system degraded to.978 per unit with a simultaneous unit trip on Unit 1 and a LOCA on Unit 2. For this condition the 13.8 kV bus drops to.903 per unit, Units 2, 4.16 kV vital and group buses dropped to.9226 per unit with the voltage at the 4.16 kv, 460 V and 230 V loads dropping to.917,.923, and.91 per unit respectively. This condition lasts for approxi-mately three minutes until the reactor coolant pumps are tripped after which the profile improves. This profile is summarized on page -1 The LTC will also move to improve this condition in 5/8% increments and 30 seconds per increment. (No credit was taken f or the LTC action at this time.) 2. The highest voltage results with the 500 kV system voltage at 1.06 per unit and hypothetical loads on each bus. 3. The greatest transient drop on the 4.16 kV vital system results upon the start of a 6,000 hp reactor coolant pump motor. This transient is worse than correction of the vital loads upon the occurrence of a LOCA. Po s t ul a t-ing a prestart condition corresponding to the 500 kV voltage degraded to.978, Unit 1, 4.16 kV loaded to the maximum continuous full load rating of the 13.8/4.16 kV station power transformer and the reactor coolant pump motor being started against a transformer which is loaded to its maximum full load rating less the KVA cor-responding to the RCP, the voltage'on the 4.16 kV group and vital buses drops to.8692 per unit. The voltages at to 460, 230 volt loads dropped to 8692 and.8543 per unit respectively. The 460 volt and 230 volt loads selected were those with the g reatest circuit impedance and horsepower representing the greatest drop. This condition lasts for approximately 25 seconds. 6

o U l Ik + l l l 4. The transient analyzed on the 460 volt vital bus was j upon the simultaneous start of the chiller, auxiliary l l building supply and vent fans and the switchgear room supply fans which results upon a LOCA signal. This corresponds to 255 Hp. The prestart condition was with the 4.16 kV sustained voltage condition in 1 above and the 460 volt load hypothetically postulated at the maxi-mum continuous rating of the transformer less the KVA of the motors being started. This transformer also has the g reatest per unit impedance of all the 460 volt vital transformers. The resulting 460 bus voltage was .8608 per unit. Individual motor starting times are e approximately 5 seconds. 5. The transient analyzed on the 230 volt vital bus was the start of a 30 hp motor on f eeder 2B3Y. This load was found to be the largest load on the smallest cable, the g reatest distance f rom the source corresponding to the g reatest circuit impedance and result in drop (see page 31). The prestart conditions correspond to the sustained 4.16 kV voltage conditioned in 1 above with l the transformer upons which the load was being started equal to the maximum rating of the transformer. The resultant MCC voltage was.8739 and.7854 at the load. WSR:aec 3L1 03/04C 1

2h 4160 V VOLTAGE Pit 0 FILE METHOD At1D ASSUMPTIONS 1. One line (attached) shows switching arrangement. 2. All transformer impedance was assumed to be reactive. 3. All transformer impedances were obtained from the transformer nameplates. The greatest impedance of a group of identical transformers were used. 4. Calculations were worked in per unit on a 1 MVA, 500 kV base. 5. Okonite cable Bulletin was used as a reference to obtain cable impedance data. 6. 4 kV loads were assumed at.91 p.f. This allows some margin. 7. Approximately 2 MVA was added to the loads on 11 and 21 station power transformer for margin. 8. Cable impedances were used. 9. PSE&G memorandum dated 10/31/78, part IV was used to ob-tain lowest system voltage. This memorandum nakes very conservative assumptions of its own. The increase in the load flow into Salem at 500 kV has an insignificant effect on the final result. This memorandum may be found in Appendix.

10. The 500 kV system which is a minimum of approximately 5000 MVA represents a negligible impedance (i.e.

1/5000 =.0002 against final circuit impedance of Q.017) loading on No. 1, 11, 21 station power transformer. 301 18A ) l l

~ o o RCP START 1. Ac tual motor data was 'used. 2.- In order to achieve a conservative result the following method was utilized. (Ref. one line.) The greatest drop would be obtained when the 500 kV system is.at its lowest attainable voltage and the other load running at the time of the RCP start is the g reatest. The latter can be attained by assuming this load to be the maximum. rating of the station power transformor less the load of the RCP. The running load on the other 13.8/4.16 station transformer is taken as its maximum rating. Further when starting a large motor which results in a significant bus voltage drop there i s an increase in the current drawn by the running motors due to reduction in the torque developed by the motor and slight speed re-duction. The results in an additional drop. This relationship is slightly greater than one for one. We have very conservatively assumed that the running load impedance decreases as the square of the bus voltage to analytically model this occurrence. 301 19A e 1 e 9 -m

~. dh 460 V VOLTAGE PROFILE The 460V voltage profile was approached so as to allow margins'as follows: 1. .B vital bus was selected as typical. Of the 3, 480 V vital buses A&B represent the greatest per unit im-pedance as they are 750 KVA, 5.75% where as C is 1000 KVA, 5.75%. 2. The load assumed connected to the 480V bus was equal to the maximum continuous rating of its transformer. i.e. B is rated 750/1000 KVA AA/FA. 1000 KVA was used and assumed at.8 p.f. 3. The cable voltage drop was approached as follows. List all the a bus loads with their f ull load amps, cable length and size, and determine the individual drops. From this select the greatest drop and apply in all cases. Thus for any feeder where the voltage drop is examined further, we can obtain less drop by refering to this calculation (i.e. the RMS was looked at further applying the 8V d rop. Had we had trouble we could have used the actual drop of 1.41.) 4. The worst transient was with the simultaneous connection of the safety related loads that are block loaded. The transient was analyzed similarly to the 4160 V, that is, using the running load prior to the start of this block connected load as the maximum continuous rating of the transformer to which it is connected. The 4160 V pre-start voltage was that corresponding to the degraded 500'kV system condition. 5. The motor locked rotor currents were assumed equal to 5 time full load amps and a .2 p.f.

40 230 V VOLTAGE PROFILE The 230V voltage profile was approached so as to allow -margins as follows: 1. B vital bus was selected as typical. 2.- The following data'was compiled as follows for each MCC feed: The actual cable size and length, the connected load (assumed all MCC f eeders closed and no diversity), the cable impedance /1000' from which the actual cable impedance was determined. The actual impedance was multiplied by the connected load amps to determine the voltage drops between the unit substation and MCC. The g reatest voltage drop between the MCC and the load was determined for each MCC 'in the same manner. These two d rops were then arithmetica11y added to arrive at.the worse case voltage drop. 3. The load connected to the 230 V bus was assumed to be equal to the maximum continuous rating of its transformer o r 300 KVA. A. 8 p.f. was also assumed. 4. The worse transient was with the start of a 30 HP motor. l The transient was analyzed similarly to the 4160 V, that is using the running load prior to the start of this block connected. load as the maximum continuous rating of the transformer to which it i s connected. The 4160 V pre-start voltage was that corresponding to the degraded 500 kV system condition. Motor locked rotor was assumed equal to 6X F.L. at.2 p.f. 301 21A t 1 i l e o u-etee e ye ,-e i

a h RCP STARTI!1G TIME t PURPOSE: The purpose of this calculation is to determine the reactor coolant pump starting times with the pump load under cold and hot conditions. Actual RCP cold start times are available for comparison of results. MET 110D & ASSUMPTIONS: 1. Actual motor and pump speed torque curves were used (attached). 2. The starting interval was divided into ten increments and the mean of each increment used in the analysis. The results of each increment were then summed. 3. Based upon previous analysis the motor terminal voltage was assumed at 85% at 4160 V for 95% of the total starting time. RESULTS: A RCP cold accelerating time was 25.46 seconds and hot was 18.33 seconds. Test results indicated an RCP starting times of 22-26 seconds e - s. ~. - 301 24A l e e emm

a CORRELATION OF FIELD TEST DATA AND CALCULATIONS PURPOSE: The purpose of those calculations was to use actual 500 kV system voltage and plant load data in the calculation of a plant load profile. The same procedure applied in the previous calculations was utilized. The results of this calculation were then composed with actual measurements. METilOD & ASSUMPTIONS: The field data was monitored over a 24 hour period by Maplewood Laboratory personnel and is attached. Readings at 1600 hours were arbitrarily selected to use in the calculations. RESULTS: As shown on the attached sheet, the results of measured and calculated compare favorably. 301 23A 6 6

Of concern in this section is the minimum steady-state voltage condition at Salem for the most. critical yet extremely unlikely combination scheduled and sudden outage situation. Exhibit 5 is a power flow transcrip-tion of an all in peak load condition simulating a PSE&G capacity emergency power import level. Exhibit 6 is a condition which simulates the maintenance outage of Salem unit #1 along with the New Freedom-De ans 500-kV line. In Exhibit 7, in addition to the previously described maintenance outages a sudden loss of the Salem-Keeney 500-kV line complicated with a stuck breaker at Salem, causes Salem unit #2 to trip leaving the auxiliary load of,44 MW at Salem to be fed radially from the New Freedom.230-kV bus.

A. I . During normal operation, the Safety Injection Pumps, Residual Heat Removal Pumps and Containment Spray Pumps are not operating except for tests. Up to five fan coolers are operating, depending upon the needs of the moment. At least one component cooling pump is operating. During normal operation, an "S" signal may be generated in error. As soon as it is discovered that the "S" signal is false, the operator must defeat the signal and secure operation of the pumps to limit or prevent lif ting of the pressurizer relief valves and eventual release of reactor coolant to the containment. The operator is locked out fo r . performing any action for up to 2 minutes following receipt of the "S" signal until the start sequence is completed. 3.2 Abnormal Conditions General The design of the Salem Safeguard System includes the requirements that the station must be safely shut down during the occurrence of a loss of coolant accident (LOCA) and a coincident loss of offsite power (blackout). All electrical equipment needed. during a LOCA is powered by the vital AC system which can be energized by standby diesel generator. The Safeguards Equipment Control (SEC) provides the necessary logic capable of initiating proper actions for any accident conditions (with possible continu-i ation of events) assumed by the design of the station. The SEC system is comprised of three independent control systems for each unit which determines the need for accident and/or blackout safety equipment, and start and load this equipment on the vital electrical system. Each SEC is independent and isolated from the others, and is associated with Rev. 3 its own diesel generator. Each SEC can control safety loads according to four modes of operation described below: 3.2.1 Injection Phase 3.2.1.1 Mode 1 LOCA (with Off-Site Power Available) Should a LOCA occur, the Solid State Protection System (SSPS) will send safety injection ("S") signal to the SEC system. The SEC initiates the following actions automatically: i

( 'ke -58a-Lockfoutmanualcontrolofsafety-relatedloads. a) b) Start diesel generators (the diesels are not connected to tje bus since of f-site power is available). ) c) Automatically load all the following safety related loads to the vital bus. - 240-480V Breaker (230V control Center Loads) Ib4 - Start SI Charging Pumps 2(Geo) no - Start Safety Injection Pumps 500 2(%oo) - Start Residual Heat Removal Pumps - Start Containment Spray Pumps (If the "P" signal-high pressure in containment occur) p,: - Start service waterpumps (alternate SW pump if the other fails to start) - Start at least four Containment Fan Coolers (low Rev. speed operation)( 2c%.

The undervoltage signals are combined in a two-out-of-three logic matrix in each SEC. If an accident has not occurred, the SEC performs the following logic sequence summarized below: a) Trip all 460 V and 4160 V vital bus breakers. b) Start diesel generators. c) Lockout manual control of all bus loads Rev. 3 until the automatic loading sequence is complete d) Close tne diesel generator ACB e) Sequence the loading of safeguard equipment required for blackout conditions as shown below: 240-480V Breaker (230V control Center Loads) ) Start SI Charging Pumps Start Component Cooling Water Pumps Start Auxiliary Feedwater Pumps Start Service Water Pumps (Alternate SW pump if previous fails to operate) Start Emergency Control Air Compressor Start Chillers 6 Start Aux.

Dear Mr. Grier:

NRC IE BULLETIN NO. 79-06C NO. 1 UNIT SALEM GENERATING STATION (- Pursuant to the subject bulletin, we hereby, submit the following response: Short-Term Actions Item 1 A. Station Emergency Procedures have been revised such that Reactor Coolant Pumps are immediately tripped upon Reactor Trip with initiation of Safety Injection caused by low reactor coolant system pressure. B. A station operating memo has been issued re-quiring the presence of two licensed operators in the control room during operation in Modes 1, 2 and 3. Item 2 A series of Loss of Coolant Accident (LOCA) analyses for a range of break sizes and a range of time lapses between initiation of break and pump trip applicable to the 2, 3 and 4 loop plants has been performed by the Westinghouse owners' Group. A report summarizing the results of the (. analysis of delayed Reactor Coolant Pump trip during small loss of coolant accidents for West-inghouse NSSS will be submitted to Mr. D. F. Ross

m....-..,..--..

n e i l ( Boyce H. Grier, Director 8-29-79 f i i 1979. In the by Mr. Cordell Reed on August 31, d~ report, maximum PCT's for each break size con-sidered and pump shutoff times have been provided. ~~ The report concludes that if the reactor coolant pumps are tripped prior to the reactor coolant system pressure reaching 1250 psia, the resulting peak clad temperatures are less than or equal to those reported in the FSAR. In addition, it is shown that there is a finite range of break sizes and RCP trip times in all cases 10 minutes or later, which will result.in PCT's in excess of 2200*F.as calculated with conservative Appendix K model.s. The operator in any event would have at least 10 minutes to trip the RCP's following a small break LOCA, especially in light of the con-servatisms in the calculations. This is appropri-i ate for manual rather than automatic action, based on the guidelines for termination of RCP operation presented in WCAP-9600. Item 3 The Westinghouse Owners' Group has developed { guidelines which were submitted to the NRC in Section 6 and Appendix A of WCAP 9600. The analy-ses provided as the response to Item 2 are con- ) sistent with the guidelines in WCAP 9600. No i changes to these guidelines are needed for both LOCA and non-LOCA transients. Item 4 The Owners' Group effort to revise emergency procedures covers many issues, including operation of the Reactor Coolant Pumps. The action taken in response to item 1 is sufficient as an interim measure in regards to these pumps. The expected schedule for revising the LOCA, steamline break and steam generator tube rupture emergency pro-cedures is the following: Mid-October: Guidelines which have been reviewed by the NRC will be provided to each utility. Appropriate utility personnel associated with writing procedures will meet with the Owners' Group Subcommittee on Procedures and Westinghouse to pro-r- (' vide the background for revising 1 their emergency procedures.

Resolution of the requirements for the analyses and an' acceptable schedule for providing the analyses and guidelines and procedures resulting from the analyses will be arrived at between the Westinghouse owners' Group and the NRC staff. I,ong Term Actions As discussed in our response to short-term item 2, we do not believe that automatic tripping of the RCP's is a required function based on the analyses that have been performed and the guidelines that We have been developed for manual RCP tripping. propose that this item be discussed with the NRC staff following their review of the owners' Group submittal. If you have any further questions on this matter we will be pleased to discuss them with you. Sincerely g/h @V \\4 g? .hs
