.EMERGENCY CORE COOLING SYSTEMS BASES .

3/4.5.4 REFUELING WATER STORAGE TANK The OPERABILITY of the RWST as part of the ECCS ensures that a sufficient supply of borated water is available for injection by the ECCS in the event of a LOCA. The limits on minimum volume and boron concentration ensure .that 1) sufficient water is available within containment to permit recirculation cooling flow to the core, and 2) the reactor will remain subcritical in the cold condition following mixing of the RWST and the RCS water volumes with all control rods inserted except for the rnst reactive control assembly.

These assumptions are consistent with the LOCA analyses.

In addition, the OPERABILITY of the RWST as part of the ECCS ensures that sufficient negative reactivity is injected into the core to counteract any positive increase in reactivity caused by RCS cooldown.

RCS cooldown can be caused by inadvertent depressuri.zation, a loss-of-cool ant accident or a steamline rupture.

The limits on contained water volume and boron concentration of the RWST also ensure a pH value of between 8.5 and 11.0 for the solution recirculated within containment after a LOCA. This pH band minimizes the evolution of iodine and minimizes the effect of chloride and caustic stress corrosion on rrechanical systems and components.

The contained water volume limit includes an allowance for water not usable because of tank discharge line location or other physical characteristics

EMERGENCY CORE COOLING SYSTEMS BASES ECCS SUBSYSTEMS (Continued)

With the RCS temperature below 350°F, one OPERABLE ECCS subsystem is acceptable without single fail.ure consideration on the basis of the stable reactivity condition of the reactor and the limited core cooling requirements.

The limitation for a maximum of one safety injection pump to be OPERABLE and the Surveillance Requirement to verify all safety injection lumps except the allowed OPERABLE safety injection pump to be inoperable below 312°F provides assurance that a mass addition pressure transient can be relieved by the o per at i o n o f a s i n g 1 e PO PS re 1 i e f v a 1 ve

The Surveillance Requirelfents provided to ensure OPERABILITY of each component ensures that at a minimum, the assumptions used in the safety analyses are ITEt and that subsystem OPERABILITY is maintained.

Surveillance requirements for throttle valve position stops and flow balance testing provide assurance that proper ECCS flows will be maintained in the event of a LOCA. Maintenance of proper flow resistance and pressure drop in the piping system to each injection point is necessary to: 1) prevent total pump flow from exceeding runout conditions when the system is in its minimum resistance configuration, 2) provide the proper flow split between injection points in accordance with the assumptions used in the ECCS-LOCA analyses, and 3) provide an acceptable level of total ECCS flow to all injection points equal to or above that assumed in the ECCS-LOCA analyses.

3/4.5.4 REFUELING WA.TER STORAGE TANK The OPERABILITY of the RWST as part of the ECCS ensures that a sufficient supply of borated water is available for injection by the ECCS in the event of a LOCA. The limits on RWST minimum volume and boron concentration ensure that 1) sufficient water is available within containment to permit *recirculation cooling flow to the core, and 2) the reactor will remain subcritical in the cold condition following mixing of the RWST and the RCS water volumes with al 1 control rods inserted except for the rrost reactive control assembly.

These assumptions are consistent with the LOCA analyses.

In addition, the OPERABILITY of the RWST as part of the ECCS ensures that sufficient negative reactivity is injected into the core to counteract any positive increase in reactivity caused by RCS cooldown.

RCS cooldown can be caused by inadvertent depressurization, a loss-of-coolant acc*ident or a steam-1 i ne rupture

The 1 imits on contained water volume and boron concentration of the RWST al so ensure a pH value of between 8.5 and 11.0 for the solution recirculated within containment after a LOCA. This pH band minimizes the evolution of iodine and minimizes the effect of chloride and caustic stress corrosion on ITEchanical systems and components.

The contained water volume limit includes an allowance for water not usable because of tank discharge line location or other physical characteristics.

Thus an analysis of smaller punp suction breaks is representative of the spectrun of. break sizes. For these analyses it was assuned that the single failure occurred on a diesel ge_nerator such that one punp and two fan coolers f af led to operate.

The 111a;ier'ity e:f the A"al,ses perfonned utilized the Westinghouse con-tail'lllent model developed for the IEEE-323-1971 Equipment Qualification progran. These models and their justification (experimental .and ical) are detailed in References 56 through 60. Some major points of the model are as follows: SGS-UFSAR 15.4-88 Revision 0 July 22, 1982

1. The saturation temperature corresponding to the pt'.rtial pressure of the contairment vapor is used in the calculation of condensing heat transfer to the passive heat sinks and the removal by ment fan coolers. 2. The Westinghouse containment model utilizes the analytical approaches described in References 6 and 60 to calculate the condensate removal from the condensate film. Justification of this model is provided in References 56, 59, 60, and 6. (For large breaks 100 percent revaporization of the condensate is used, and a calculated revaporization due *to convective heat flux is used for small breaks.) 3. The small steCITI line break containment analyses uti l1zed the nant TagC1ni correlation, and the large steCITI line break analyses utilized the Tagami correlation with an exponential

The details of these models are given in Reference

" o.

There are two valves in each main feedwater line wnich serve to isolate main feed flow following a stec111 line break. One is the main feed regulator valve W1ich receives dual, separate train trip signals from the plant protection system on any safety injection signal and closes within five seconds of receipt. of this signal. The second is the feed line isolation valve W1ich also receives dual. separate train trip sf gnal s from the protection system fo llowf ng a safety injection signal. This valve closes within 30 seconds. Additionally, the main feed punps receive dual, separate train trip signals from the protection system following a stec111 line break. Thus. the worst failure in this system is* a failure of the main regulator valve to close. This results in an additional 25 seconds during W1ich feedwater from the condensate feed may be added to the steam generator.

Also. since the feed tion valve is upstream of the regulator valve, failure of the regulator results in additional feed line volL1T1e which is not isolated from the stean generator.

Thus, water in this portion of the lines can flash and enter into the stean generator.

The only non-safety grade equipment in the main feed system W1ich is relied upon to tenninate the main feed flow to the stean generators are the main feedwater control valves. These valves are not seismic category I. Ho\!Ever, each valve receives dual, independent, safety grade trip:.elosed signals from the protection system following a stec111 line break. A1so. the valves are air-9perated fail-closed design. Since the assLITled break is inside contairment in a seismic category I pipe, it is not assuned to be i ni ti ated by a seismic event. Therefore, to ass1J11e a coincident sei smfc event with the hypothetic al pipe rupture is not required, and thus a seismic classification for the main feed SGS-UFSAR

regulation valve is not necessary to insure closure following a

li ne break inside contai r111ent. Because of the conservative nature of the transient calculations used for the 1971 Equipment Qualification Progran, the results of thfl Salem temperature transient calculatf on wf 11 fall under the peak transient calculated for the 1971 Equipment Qualification ProgrC111 and presented in Reference 60 (approximately 385.F). The pressure transient wf 11 fall below the design limits for the Salem 2 contail'lllent.

Feedwater flow to the faulted steC111 generator from the main feed system is calculated using the hydraulic resistances of the system piping, head/flow curves for the main and the steC111 generator sure deczy .as calculated by the MARVEL code. In the calculations fonned to match these systems variables, a variety of assunptions are made to maximize the ca le ul ated flows. These f nc l ude: 1. No credit for extra pressure drop in the feed lines due to flashing of feedwater.

2. Feed regulator valve in the faulted loop f s full open. 3. Feed regulator valves in the intact loop do not change position prior to a trip signal.aREi elese iAstaRtly ef a sigAal te e lase. 4.

Since all main stean isolation valves have closing times of no more than five seconds, failure of one of these valves affects only the volune of the main stean and turbine stean piping htlich cannot be isolated from the pipe r14>ture.

4 ef W6i\.? 8822Eii1 and Table 15.4-23 shows the mass in the stean lines with and without an isolation valve failure at the four levels considered in the analyses.

Stean contained in the unisolated portions of the stec111 lines and bine plant considered in the contairment analyses in t"'10 For the large double-ended ruptures, stean in the unisolated steam lines is released to the contairment as part of the reverse flow. This is plished by having the reverse flow begin at the time of the break at the Moody critical flow rate for stean as established by the cross-sectional area of the stean line and the initial stec111 pressure.

The flow is held constant at this rate for a time period sufficient to purge the entire unisolated portion of the stean lines. Enthalpy of the flow is also held constant at the initial stean enthalpy.

Following the period of constant flow representing purging of flow from the intact stean generators, as calculated by f¥cRVEL, is added to the con-tai rment and continues until stean line isolation is complete.

When considering the split r14>tures, stec111 in the steam lines is inc 1 uded in the an a ly si s *by addi ng the tot a 1 *mass in the 11 ne s to the . initial mass of stean in the faulted stean generator.

This is necessary because, unlike double-ended ruptures, the total break area for a split is unchanged by steam line isolation; only the source of the blowdown effluent is changed. Thus, stec111 flow from the piping in the intact SGS-UFSAR 15.4-92 Revision O July 22, 1982

loops is indistinguishable fran steam leaving the faulted stean generator.

The suction and discharge pressures of each auxiliary feedwater pump are indicated on the control console. The auxiliary feedwater flow. tions for each steam generator are mounted on the control counsole next to each other, allowing the operator to easily view and compare flows. In addition to the above mentioned indications, high steam flow, low steam pressure, and steam-feed fl ow deviation condi tfons for each steam generator are alarmed on the main control console in the control room. Alanns for these conditions are also provided on the overhead annunciator.

Since a sufficient number of trains of instrumentation must be available for nonnal plant operation, steam generator instrumentation will be in operation at the time of the postulated event. Therefore, changes in steam generator pressure and steam flow will be detected as they occur. The only delay expected in transmitting the infonnation to the control room is the time required for the instrumentation to react to the changing conditions.

This delay is expected to be no more than a few seconds. Failure of the auxiliary feedwater isolation valve to close has not been considered.

The maximum auxiliary feedwater flow that can be delivered to a faulted steam been assumed in the analysis for ten minutes considered:

1) F'WRewt pPeteetieA 6f3el"a'

2) failure of runout protection.

Only after ten minutes the operator takes action to isolate auxiliary feedwater isolation valves fails to close, the operator can trip the two auxiliary feedwater pumps feeding broken steam generator until this valve or* another in the line is manually closed. The pump curves for the Auxiliary Feed pump are shown in Figure 15.4-93 (Steam Driven) and Figure 15.4-94 (Electrical Driven). A schematic of the Auxiliary Feed System is shown fn Figure 10.4-17

15.4.8.2.3 Heat Sinks The worst effect of a contair111ent safeguards failure is the loss of a spray pump which reduces containment spray flow by 50 percent. In al 1 analyses, the times ass1111ed for of contair111ent spra1s and fan coolers are 59 and 35 seconds re spec ti vely following the appropriate initiating trip signal. These times are based on the a loss of offsfte power and the delays are consistent with Technical ification limits. The delay time for spray delivery includes the time required for the spray pumps to reach full speed and the tfme required to fill the sprai headers and piping. The saturation temperature corresponding to the partial pressure of the vapor in the contairment is conservatively assumed for the temperature in the calculation of condensing heat transfer to the passive heat sinks.

The large break case resulting in the calculated peak pressure has been ent;fied as the i*.4 ft2 break at 70 percent power. This case re lted in a peak pressure of 39.l psi g when dry steam bl owdowns are used. When this same case was reanalyzed utilizing blowdowns which include the effect of liquid carryover from the secondary

side, ting eak pressures were 37. 7 and 37.2 using the Westi ngh se and NRC contai nt models respectively.

This indicates the over. 1 con-servatism of e Westinghouse containment model when used th dry steam, vs. usi n the expected mass and energy releases ch include the effect of entrai nt. Transients for the Westi nghous mode.1 with dry steam blowdowns are ovided in Figures 15.4-97 thro h 15.4-99. The case resulting

nth calculated peak pressu has been identified as the .86 ttf. break at 1 for the small breaks percent power. The resulting peak pressure for is case was 4 reanalyzed*

utilizing the NRC c psig. When this case was del, and the same mass and pressure was found to be 43.0

psig. The transients for the Westi use model are provided in Figures 15.4-100 through 15.4-102.

Similar nsients for the case which used the NII: model are provided in Fig es l 4-103 through 15.4-105.

The case resulting in the cal lated peak te erature has been identi-fied as the 0.908 ft2brea at 70 percent powe This case resulted in a peak temperature of 3.5 *F. When this sam case was analyzed with the NRC containment mo l a peak temperature of 34 °F was calculated.

These results verify hat the Westinghouse and NRC m els yield similar results. Transi en s for both of these cases have been Figures 15.4-106 hrough 15.4-108.

The containment response to such leakage would be a gradual pressure and temperature rise whfchjtould reach a pressure peak of slightly less* than two pounds gauge.

15.2.12.l Results Figure 15.2-38 illustrates the flux transient following the accident.

Reactor trip on overtemperature occurs as shown in Figure 15.2-38. The pressure decay transient following the accident is given in Figure 15.2-39. The resulting DNBR never goe*s below 1.30 as shown in Figure 15.2-40. 15.2.12.4 Conclusions The pressurizer low pressure and the overtemperature Reactor tion System signals provide adequate protection against this accident, and the minimum DNBR remains in excess of 1.30. 15.2.13 ACCIDENTAL DEPRESSURIZATION OF THE MAIN STEAM SYSTEM Identification of Causes and Accident Description ere core conditions resulting from an accidental ization of the ain Steam System are associated with an ina opening of a sing steam dump, assuming a upture of a main steam pipe 15.\)' The steam release as a consequ ce of s accident results in an . initial increase in steam flow whi decreases during the accident as the steam p-ressure.falls.

15.2.13 ACCIDENTAL DEPRESSURIZATION OF THE MAIN STEAM SYSTEM 15.2.13.l IDENTIFICATION OF CAUSES AND ACCIDENT DESCRIPTION The most severe core cond1t1ons result1ng from an acc1dental depressur1zation of the Ma1n Steam System are assoc1ated w1th an 1nadvertent opening of a single steam dump, relief or safety valve. The analyses performed assuming a rupture of a main steam p1pe are g1ven 1n Section 15.4.3. The steam release as a consequence of this acc1dent results 1n an initial increase in steam flow which during the accident as the steam pressure falls. The energy removal from the Reactor Coolant System causes a reduction of coolant temperature and pressure.

In the presence of a negative moderator temperature coefficient, the cooldown results in a reduction of core shutdown margin. The analysis is perfcrmed to demonstrate that the following criterion is satisfied:

Assuming a stuck rod cluster control assembly, with or without offsite power, and assuming a single failure in the Engineered Safety Features there will be no coasequential fuel damage after reactor trip for a steam release equivalent to the spurious opening, with failure to close, of the largest of any single steam dump, relief or safety valve. This criterion is satisfied by verifying the DNB design basis is met. The following systems provide the necessary protection against an accidental depressurization of the Main Steam System: l. Safety injection System actuation from any of the following:

3. Redundant 1solat1on of the ma1n feedwater 11nes: Susta1ned high feedwater flow would cause additional cooldown.

Therefore, 1n addition to the normal control act1on wh1ch will close the main feedwater valves following reactor tr1p, a safety injection signal w111 rap1dly close all feedwater

-control valves, tr1p the main feedwater pumps, and close the back up feedwater isolation valves. 15.2.13.2 METHOD OF ANALYSIS The follow1ng analyses of a secondary system steam release are for th1 s section.*

1. A full plant digital computer simulation, LOFTRAN (Ref. 4), is used to determine Reactor Coolant System temperature and pressure during cooldown.

2. An analysis to determine that there is no consequential fuel damage . . The following conditions are assumed to exist at the time of a secondary system steam release: 1. End of life shutdown margin at no load, equilibrium xenon conditions, and with the most reactive assembly stuck in its fully withdrawn positiori.

Operation of rod cluster control assembly banks during core-burnup is restricted in such a way that addition of positive reactivity in a secondary system break accident will not lead to a more adverse condition than the case analyzed.

2. A negative moderator coefficient corresponding to the end of life rodded -core with most reactive rod cluster control assembly in the fully withdrawn positi.on.

The variation of the coefficient with temperature and pressure is included.

The keff versus temperature at 1000 psi corresponding to the negative moderator temperature coefficient used plus the Doppler temperature effect is shown in Figure 15.2-41 . S G -U i=

3. Minimum capability for injection of high concentration boric acid solution corresponding to the most single failure in the Safety Injection System. The injection curve used is shown in Figure 15.2-42. Th1s corresponds to the flow delivered by one charging pump delivering its full contents to the cold leg header. No credit has been taken for the low concentration boric acid which must be swept from the safety injection lines downstream of the Refueling Water Storage Tank (RWST) prior to the delivery of boric acid (2,000 ppm) to the reactor coolant loops. 4. The case studied is an initial total steam flow of 228 lbs/second at 1015 psia from one steam generator with offsite power available.

This is the maximum capacity of any single steam dump or safety valve. Initial hot shutdown conditions at time zero are assumed since this represents the most pessimistic initial condition.

Should the reactor be just critical or* operating at power at the of a steam release, the reactor will be tripped by the normal overpower protection signals when power level reaches a trip point. Following a trip at power the Reactor Coolant System contains more stored energy than at no load, the average coolant temperature is higher than at no load and there is appreciable energy stored in the fuel. Thus. the additional stored energy is removed via the cooldown caused by the steam line .break before the no load conditions of Reactor Coolant System temperature and shutdown margin assumed in the analyses are reached. After the additional stored energy has been removed, the cooldown and reactivity insertions proceed in the same manner as in the analysis which assumes no load condition at time zero. However, since the initial ste.am generator water inventory is greatest at no load, the magnitude and of the Reactor Coolant System cooldown are less for steam line breaks occurring at power. 5. In computing the steam flow the Moody Curve for fl/D = O is used. 6. Perfect moisture separation in the steam generator is assumed. SGS-

15.2.13.3 RESULTS The results presented are a conservat1ve 1nd1cat1on of the events which would occur assum1ng a secondary system steam release s1nce 1t 1s postulated that all of the cond1t1ons descr1bed above occur s1multaneously.

F1gure 15.2-43 shows the trans1ent ar1s1ng as the result of a steam release hav1ng an 1n1t1al steam flow of 228 lbs/second at 1015 ps1a w1th steam release from one safety valve.

The assumed steam release 1s typ1cal of the capac1ty of any s1ngle steam dump or safety valve. In th1s case safety 1nject1on is 1nitiated automat1cally by low pressurizer pressure.

Operation of one centrifugal charging pump 1s considered.

Boron solut1on at 2,000 ppm enters the Reactor Coolant System providing suff1c1ent negat1ve reactivity to assure no fuel damage. A DNB analysis was performed for this case and the minimum u DNBR was above the 11m1t val1e of 1.3. The react1v1ty transient for the case shown 1n F1gure 15.2-43 1s more severe than that of a failed steam generator safety or relief valve Which is terminated by steam line differential pressure, or a failed condenser dump valve which is terminated by low pre1surtzer pressure.

The transient 1s quite conservative w1th respect to cooldown.

s1nce no credit 1s taken for the energy stored in the system metal other than that of the fuel elements or the energy stored in the other steam generators.

the trans1ent occurs over a period of about ten minutes, the neglected stored energy 1s 11kely to have a s1gn1ficant effect in slow1ng the cooldown.

15.4.2 MAJOR SECONDARY SYSTEM PIPE RUPTURE 15.4.2.1 IDENTIFICATION OF CAUSES AND ACCIDENT DESCRIPTION The steam release arising from a rupture of a main steam pipe would result in an initial increase in steam flow which decreases during the .accident as the steam pressure falls. The removal from the Reactor Coolant System causes a reduction of coolant temperature and pressure.

In the presence of a negative moderator temperature coefficient, the cooldown results in a reduction of core shutdown margin. If the most reactive rod cluster control assembly is assumed stuck in its fully withdrawn position after reactor trip, there is an increased possibility that the core will become critical and return to power. A return to power following a steam pipe rupture is a potential problem mainly because of the high power peaking factors which exist assuming the most reactive rod cluster control assembly to be stuck in its fully withdrawn position.

The core is ultimately shutdown by the boric acid injection delivered by the Safety Injection System. The analysis of a main steam pipe rupture is performed to demonstrate that the following criteria are satisfied:

1. Assuming a stuck rod cluster control assembly, with or without offsite power, and assuming a single failure in the engineered safeguards there is no consequential damage to the primary system and the core remains in place and intact. 2. Energy release to containment from the worst steam pipe break does not cause failure of the containment structure.

Although DNB and possible clad perforation following*

a steam pipe rupture are not necessarily unacceptable, the following analysis, in fact, shows that no DNB occurs for any rupture assuming the. most reactive assembly stuck in its *fully withdrawn position . SGS-UF.SA.'2..

8920QilD'070SSS IS* 4-.r' The fo11ow1ng functions provide the protection against a steam pipe

rupture: 1. Safety 1njection system actuation from any of the following:

a. Two-out-of-three channels of low pressurizer pressure b. High differential pressure signals between steam lines c. High steam 11ne flow in two main steam lines (one-out-of-two per line) 1n coincidence with either low-low Reactor Coolant System average temperature or low steam line pressure in any two lines. d.

high containment pressure 2. The overpower reactor trips (neutron flux and 6T) and the reactor trip occurring in conjunction with receipt of the safety injection signal. 3. Redundant isolation of the main feedwater lines: Sustained high feedwater flow would cause additional cooldown.

Therefore.

in add1t1on to the normal control action which will close the main feedwater valves, a safety injection signal will rapidly close all feedwater control valves, trip the main feedwater pumps, and close the feedwater pump discharge valves. 4. Trip of the fast acting steam line stop valves (designed to close in less than 5 seconds) on: a. High steam flow in two main steam lines in coincidence with low-low Reactor-Coolant System average temperature or low steam line pressure in any two iines. b. High-high containment pressure SGS-8920Q:lQ/Q1Q88§ IS.4-l7

Fast-act1ng valves are prov1ded 1n each steam line that will fully w1thin 7 seconds of a signal to close (including instrumentation delays). For breaks downstream of the isolation valves, closure of all valves would completely terminate the blowdown.

For any break, in any location, no more than one steam generator would blowdown even if one of 'the 1solat1on valves fails to close. A description of steam line isolation is included in Chapter 10. Steam flow 1s measured by monitoring dynam1c head in nozzles inside the steam pipes. The nozzles which are of considerably smaller diameter than the main steam pipe are located inside the containment near the steam generators and also serve to limit the maximum steam flow for any break further downstream.

15.4.2.2 METHOD OF ANALYSIS The analysis of the steam pipe rupture has been performed to determine:

l. The core heat flux and Reactor Coolant System temperature and pressure resulting from the cooldown following the steam line break. The LOFTRAN[2?] code has been used. 2. The thermal and hydraulic behavior of the core following a steam line break. A detailed thermal and hydraulic digital-computer code, THINC, has J been used to determine if DNB occurs for the core conditions computed in (l) above. The following conditions were assumed to exist at the time of a main steam line break. ace i de_nt. l. End of life shutdown margin at no load, equilibrium xenon conditions, and the most reactive assembly stuck in its fully withdrawn position:

Operation of the control rod banks during core burnup is restricted in such a way that addition of posit1ve reactivity in a steam line break accident will not lead to a more adverse condition than the case analyzed.

The negat1ve moderator coeff1c1ent correspond1ng to the end of life rodded core with the most reactive rod in the fully withdrawn position:

The variation of the coefficient with temperature and pressure has been included.

The keff versus temperature at 1000 psi corresponding to the negative moderator temperature coefficient used is shown in Figure 15.4-48. The effect of power generat1on in the core on over-all reactivity is shown in Figure 15.4-49. The core properties associated with the sector nearest the affected steam generator and those associated with the remaining sector were conservatively combined to obtain average core properties for reactivity feedback calculations.

Further, it was conservatively assumed that the core power distribution was uniform. These two conditions cause underprediction of the reactivity feedback in the high power region near the stuck rod. To verify the conservatism of this method, the reactivity as well as the power distribution was checked. These core analyses considered the Doppler reactivity from the high fuel temperature near the stuck RCCA, moderator feedback from the high water enthalpy near the stuck RCCA, power redistribut1on and nonuniform core inlet temperature effects. For cases in which steam generation occurs in the high flux regions of the core, the effect of void formation was also included.

It was determined that the reactivity employed in the kinetics analysis was always larger than the reactivity calculated for all cases. These results verified conservatism; i.e., underprediction of negative reactivity feedback from power generation.

3. Minimum capability for injection of boric acid (2,000 ppm) solution corresponding to the most restrictive single failure in the safety injection 9'YStem. This corresponds to the flow delivered by one charging pump delivering its full flow to the cold leg header. Low concentration boric acid (<2,000 ppm) must be purged from the safety injection lines downstream of the Refueling Water Storage Tank prior to the delivery of boric acid to the reactor coolant loops. This effect has been allowed for in the analysis by assuming the lines to contain unborated water. The modeling of the Safety Injection System in LOFTRAN is described in Reference

27. S.GS-U\:.SAfl....

15"*4-15

For the cases where offsite power is assumed. the sequence of events in the Safety Injection System is the following.

After the generation of the safety injection signal (appropriate delays for instrumentation.

logic and signal transport included), the appropriate valves begin to operate and the high head injection pump starts. In an additional 12 sec, the valves are assumed to be in their final position and the pump is assumed to be at full speed. The volume containing the unborated water is purged before the 2,000 ppm boron reaches the core. This delay, described above, is inherently 1ricluded in the modeling.

In cases where offsite power is not available, a 12-sec delay is assumed to start the diesels and to load the necessary safety injection equipment onto them. 4. Four combinations of break sizes and initial plant conditions have been considered in determining the core power and Reactor Coolant System transients:

5. a. Complete severance of a pipe outside the containment, downstream of the steam flow measuring nozzle, with the plant initially at no load conditions, full reactor coolant flow with offsite power available.

b. Complete severance of a pipe inside the containment at the outlet of the steam generator with the plant initially at no load conditions with offsite power available.

c. Case (a) above with loss of offsite power simultaneous with the initiation of the safety injection signal. Loss of offsite power results-in coolant pump coastdown.

d. Case tb) above with the loss of offstte power simultaneous with the initiation of the safety injection signal. Power peaking factors corresponding to one stuck RCCA and non uniform core inlet coolant temperatures are determined at end of core life. The coldest core inlet temperatures are assumed to occur in the sector with the stuck rod. The power peaking factors account for the effect of the UFSA'-.. -e92ee .1 e/01eees . \5*4-'2.0

** local void in the region of the stuck control assembly during return to power phase following the steam line break. This void in conjunction with the large negative moderator coefficient partially offsets the effect of the stuck assembly.

The power peaking factors depend upon the core power, temperature, pressure, and flow, and thus, are different for each. case studied. All the cases above assume 1n1t1al hot shutdown conditions at time zero since th1s represents the most pessim1st1c initial condition.

Should the reactor be just cr1tical or operating at power at the time of a steam line break, the reactor will be tripped by the normal overpower protection system when power level reaches a trip point. Following a trip at power the Reactor Coolant System contains more stored energy than at no load, the average coolant temperature 1s higher than at no load and there is appreciable energy stored 1n the fuel. Thus, the additional stored energy is removed via the cooldown caused by the steam line break before the no load conditions of Coolant System temperature and shutdown margin assumed 1n the analyses are reached. After the add1t1onal stored energy has been removed, the and reactivity insertions proceed in the same manner as in the analysis which assumes no load condition at time zero. However, since the in1tial steam generator water inventory is greatest at no load, the magnitude and duration of the Reactor Coolant System cooldown are less for steam line breaks occurring at power. 6. In computing the steam flow during a steam line break 0 the Moody Curve[2 S] for fl/D = 0 is used. 7. Perfect moisfure separation in the steam generator is assumed. The assumption leads to conservative results since, in fact, considerable water would be discharged.

Water carryover would reduce the magnitude of the temperature decrease in the core and the pressure increase in the containment . SC.S-UFSAk 8920Q.l9197ll85

15.4.2.3 RESULTS

The results presented are a conservative indication of the events which would occur assuming a steam line rupture since it is postulated that all of the conditions described above occur simultaneously.

15.4.2.4 CORE POWER AND REACTOR COOLANT SYSTEM TRANSIENT o.. ..... ct rS* 4-so 3 the Reactor Coolant System transient and core heat flux following a main steam pipe rupture (complete severance of a pipe) outside the containment, downstream of the flow measuring nozzle, at initial no load condition (case a). The break assumed is the largest break which can occur anywhere outside the containment either upstream or downstream of the isolation valves. Offsite power is assumed available such that full reactor coolant flow exists. The transient shown assumes an uncontrolled steam release from only one steam generator.

Should the core be critical at near zero power when the rupture occurs the initiation of safety injection by high differential pressure between any steam line and the remaining steam lines, or by high steam flow signals in coincidence with either low-low Reactor coolant System temperature or low steam line pressure will trip the reactor. Steam release from more than one steam generator will be prevented by automatic trip of the fast action isolation valves in the steam lines by the high steam flow signals in coincidence with either low Reactor Coolant System temperature or low steam line pressure.

The steam line isolation valves are designed to be fully closed in less than 5 seconds after receipt of closure signal with no flow through them. With the high flow existing during a steam line rupture the valves will close considerably faster.

before boron solution at 2,000 ppm enters the Reactor Coolant system from the Safety Injection System. The delay time consists of the time to receive and actuate the safety inje.ction signal and the time to completely open valve tra1ns 1n the safety 1njection lines. The safety injection pumps are then ready to deliver At th1s stage a further delay time 1s 1ncurred before 2,000 ppm boron solution can be 1njected to the Reactor Coolant System due to low concentration solution being purged from the safety 1nject1on 11nes. A peak core power well below the nominal full power value is atta1ned.

The calculation assumes the boric acid is mixed with. and diluted by the water flowing in the Reactor Coolant System prior to entering the reactor core. The concentration after mixing depends upon the relative flow rates in the Reactor Coolant System and in the Safety Injection System. The variation of mass flow rate in the Reactor Coolant system due to water density changes is included in the calculation as in the variation of flow rate from the Safety Injection System and accumulator due to changes 1n the Reactor Coolant System pressure.

The Safety Inject1on System flow calculation includes the line losses in the system as well as the pump head curve. The accumulators provide the addit1onal source of borated water if the RCS pressure decreases to below 580 psia.

and show the responses of the sal1ent parameters for cases c and d which correspond to the cases discussed above with additional loss of offsite power at the time the safety injection signal is generated.

The Safety Injection System delay time 1ncludes 12 seconds to start the diesel (including instrumentation delay time) and 12 seconds to get the safety injection pump to full. speed. In each case criticality is achieved later and the core power increase is slower than in the similar case w1th offsite power available.

The ability of the emptying steam generator to extract heat from the Reactor Coolant System is reduced by the decreased flow 1n the Reactor Coolant System. For both these cases the peak core power remains well below the nominal full power value. It should be noted that follow1ng a steam 11ne break only one steam generator blows down completely.

Thus, the remaining steam generators are still available for dissipat1on of decay heat after the initial transient is over. In the case of loss of offsite power this heat is removed to the atmosphere via the steam line safety* valves which have been sized to cover this condition.

The sequence of events is shown on Table 15.4-1. 15.4.2.5 MARGIN TO CRITICAL HEAT FLUX A DNB analysis was performed for the three cases most critical to DNB. It was found that all cases had a minimum DNBR greater than 1.30. 15.4.2.6 OFFSITE DOSES The off-site doses resulting from the steam line break accident, assuming a primary to secondary steam generator tube leak in the intact steam generators, were calculated.
