SUMMARY

The purpose of this study was to evaluate the power level at which safe shutdown and Appendix R cooling can be performed using EES cooldown without exceeding the maximum fuel temperature of 2900*F and without boiling in secondary side of steam generators. Safe Shutdown and Appendix R Cooldown transients on a single loop (6 modules) following a , 1.5 h interruption of forced cooling, were studied to evaluate fire water cooling capability with open vent lines. Three cases were studied: one case with cooldown on equipment satisfying Environmental Qualification (EQ) testing requirements, the EQ case; a second and third case using equipment satisfying 10CFR50 Appendix R requirements, the Appendix R cases. The EQ case involves the firewater system in an open loop arrangement for supplying water to the steam generator and Pelton wheels. The Appendix R cases involve water supply from (1) the condensate system (Train A) and (2) the firewater system (Train B), , both operating open loop for 5 h followed by closed loop operation. Ccnditions for the EQ case included 940 spe of 80*F firewater flow to the Economizer Evaporator Superheater (EES) sections of six steam generator modules in one loop with helium flow adjusted to maintain 255'F steam generator water exit temperatare at 76 psia indicated pres s ure. Conditions for the Appendix R Train A case included 100*F, 700 gpm condensate flow to the EES section of one loop with helium flow adjusted to maintain 311*F steam generator water exit temperature at 198 psia indicated pressure for the first 5 h of the cooldown. After 5 h the cooling in the Train A case was transferred from open to closed loop with water flow decreased to 491 gpm with helium flow then adjusted to maintain 368'F steam generator water exit temperature at 268 psia indicated pressure. The conditions for the Appendix R Train B case include 80'F, 996 gpa firewater flow to the EES section of one loop with heliam flow adjusted to maintain 257'F steam generator water exit temperature at 76 psia indicated pressure for the first 5 h of the cooldown. After 5 h the cooling was transferred from cpen to closed Page 4

909269/A loop with water flow decreased to 789 gpm with helium flow adjusted to maintain 257*F water exit temperaature at 97.8 psia indicated pressure. The liner cooling system was assumed to be unavailable for all cases. 4 The results from the transient predictions showed a cooldown can be obtained from 855 feedwater flow (87.5% power) using EQ equipment and about 80% feedwater flow (83 25 power) using Appendix R equipment. The helium flow required to maintain subcooled water conditions at EES exit varied between a minimum of 1.45 (13.6 lb/s) and a maximum of 3.8% (37 lb/s). This is within the operating range of a single circulator on Pelton wheel. The peak fuel temperature, as predicted by the RECA code, was 2858*F for the EQ case, 2875'F for the Appendix R Train A case and 2644*F for the Train B case. These are below * 'e FSAR 2900*F limit. Primary coolant pressure stayed below the prestressed concrete reactor vessel (PCRV) relief valve setpoint. The reheater and EES sections of the steam generator were maintained within allowable operating limits throughout the cooldown transient. The boiling margin in the hot module was 12*F below boiling for the EQ case, 23'F below boiling for the Appendix R Train A case, and 18'F below boiling for the Train B case. Based on the above results, it was concluded that an acceptable EES cooldown can be obtained

rom 87.55 power using firewater (EQ equipment) and from about 83 2% power using Appendix R equipment.

2. INTRODUCTION ,

At the request of PSC, GA Technologies Inc., in conjunction with Proto-Power Corporation, have performed evaluations of " safe shutdown cooling" as described in updated FSAR Sections 10 3 9. 10.3.10, and 14.4.2.2. In Ref. 1 it was pointed out that steaming as predicted in the FSAR in the main bundle (EES) of the steam generator may degrade secondary coolant flow rate to the degree that safe shutdown cooling could be compromised. The analysis in the FSAR was based upon 1000 gpm firewater flow to the EES modules of one loop and slightly less than 35 helium flow provided by boosted firewater to one circulator Pelton drive. This study represents a follow-on effort to- the Re'. I study. This study presents evaluations made to determine power levels at which safe shutdown cooling can be performed using EES without boiling in secondary system and without exceeding max fuel temperature of 2900'F. In Ref. 2, 1.5 h delay EES cooldowns were evaluated for firewater and condensate water flow at 395 and 785 power for the existing design configuration. The purpose of this study is to evaluate similar cooldowns from a higher power level with design modification in secondary water circuit. For this study a new 6-in. vent line was included in ?.he firewater and condensate cooldown, (open loop) case that was not used in the Ref. 2 study. Three limiting cooldown methods were established that involve either the firewater system for a cooldown on equipment satisfying EQ i l t ! Page 6

f 909269/A requirements or the condensate or firewater system for cooldown on equipment satisfying the 10CFR50 Appendix R requirements. The condi-tions specified for these three cooldown cases are as follows: EQ Case:

1. 940 spa of 80'F water is supplied to the EES for entire cooldown transient from the firewater system in an open- (open to atmosphere) loop configuration as shown in Fig. 2-1,

2. Water temperature of 255'F is maintained at steam generator exit at an indicated pressure of 76 psia (elevation 4820 f t).

Appendix R Train A Case:

1. 700 gpm of 100*F water is supplied to the EES for initial 5-h period of the cooldown transient from the condensate system in an open loop configuration as shown in Fig. 2-2. Water flow from the steam generator is assumed to be vented to the atmosphere via the new 6-in. vent lines located in the module exit lines.

2. After the initial period, cooling is switched to a closed-loop configuration as shown in Fig. 2-3 with 491 spm of 139'F condensate supplied to the EES.

3 Steam generator water exit temperatures are controlled to 311 *F at 198 psia for open loop and 368'F at 268 psia for closed loop operation. Appendix R Train B Case:

1. 996 gpm of 80*F water is supplied to the EES for initial 5-h period of the Jooldown transient from the firewater system in an open loop configuration, as shown in Fig. 2-4. Water flow I

909269 / A from the steam generator is assumed to be vented to the atmosphere via the new 6-in. vent lines located in the module exit lines.
2. After the initial period, cooling is switched to a closed loop configuration with 789 gpm of 80*F firewater supplied to the EES as shown in Fig. 2-5.
3 steam generator water exit temperatures are controlled to 257'F at 76 psia for open loop and 257'F at 97.8 psia for closed loop operation. The temperatures selected for steam generator exit represent mean module temperatures that provide sufficient subcooling margin to prevent boiling in the hottest modules throughout the cooldown transient. Table 2-1 summarizes the operating conditions for the three cases. The heat duty capability shown in this table is the maximum capability of the secondary system. During latter portions of the cooldown transient, heat removal is primary as opposed to secondary system limited. Actual heat removal in this case will be less than the maximum secondary system heat duty capability shown in Table 2-1. Page 13

9 909269/ A 3 ANALYSIS Several computer codes were used to perform the evaluation of the EES cooldown. Steam generator performance was obtained using the TAP code. For detailed core performance, the RECA code was used. The SUPERHEAT code was used to determine required helium flow rates for input to the RECA code. Also, the SUPERHEAT code provided a more detailed steam generator water side pressure drop. Hot and cold heliam temperatures during the 1.5-h delay were obtained from a previous analysis that used the RATS AM code (Ref. 4) . The overall water side pressure drop calculations were performed by Proto-Power (see Ref. 2) . The same versions of the TAP and RECA codes, which are the basis for the FSAR analyses, were used for this analysis. The following aections briefly discuss the analysis performed in evaluating the EES cooldown cases. 31 Water Side Pressure Drop Evaluation A key parameter in the evaluation of the EES cooldown is the water side (secondary side) pressure drop. This pressure drop includes the line and valve pressure drops from the supply pump (either condensate or firewater pumps) to the steam generator; the pressure drop in the ateam generator; and the pressure drop of the steam lines from the steam generator to the atmospheric vent, the condensate storage tank, or back to the supply pump, depending on the flow path. Appendix A describes the secondary side flow paths for the EES water flow. The overall pressure required to pass the water flow through these flow paths must I be within the available pressure capability of the water supply pumps. l Appendix A also shows the condensate and firewater pump head versus flow curves used in the pressure drop evaluation. l The required pressure drop of the secondary side is the sum of the pressure drops described above. The water side flow and pressure drops were determined by Proto-Power Corporation. Also, the available l pressure at the steam generator inlet (feedwater ring header) plotted as l l Page 15
909269/A a function of firewater flow through the steam generator was determined by Proto-Power and is presented in Appendix A. 3.2 Secondary System Evaluation The heat transfer and pressure drop for the secondary side of steam generator (water / steam) was evaluated using the TAP (Ref. 5) and the SUPERHEAT (Ref. 7) codes. TAP is a single-loop transient analysis model of the entire plant, and SUPERHEAT is a steady-state model of the steam generator. The TAP code was used primarily to evaluate the steam generator transient performance; however, the TAP heat transfer results were verified by comparison with the SUPERHEAT results. In order to obtain proper secondary system evaluation, the follow-ing calculational procedure was used:
1. Helium flow rates were determined from the SUPERHEAT code.
The SUPERHEAT calculation was performed for different time points in the cooldown transient to determine the required helium flow necessary to maintain the required water temperature at the steam generator outlet. These flow rates were then used as input for the RECA code.
2. Steam generator helium inlet temperatures obtained from the RECA code were used as input to the TAP code to evaluate steam generator transient performance. Circulator inlet helium temperatures obtained from the TAP code were used as input to the RECA code.
3 During the initial 1.5-h delay period (interruption of forced cooling), some reverse flew occurs in the primary coolant loop due to natural convection. A previous analysis of this effect was performed with the RATS AM code (see Ref. 4) . Hot and cold l i l Page 16
909269/A helium temperatures were estimated based on results from this study and were input to TAP and RECA for the 1.5-h delay period. 4 The steam generator performance 'or hot module was evaluated using SUPERHEAT code at the maximum hot to average module helium temperature time point. 33 Primary Side Evaluation The core cooling evaluation was performed using the RECA code (Ref. 6). RECA is a detailed model of the Fort St. Vrain (FSV) core which provides calculations of the helium and solid temperatures throughout the 37 fuel regions. Helium flow rates from the SUPERHEAT code and circulator inlet helium temperature from the TAP code were input to the RECA code, and the steam generator helium inlet temperatures from RECA were input to the TAP code. 3.4 Hot Module Analysis The inlet helium temperature for a given steam generator module could be higher or lower than the core exit plenum average temperatare due to flow and temperature imbalances among the various regions and the relative location of a given module to specific core regions. Mixing occurs as the gas flows through the steam generator due to turbulence and cross-flow paths resulting from tube bundles and other flow path obstacles. The objective in this study is to prevent boiling in the hot module, which could result in reduced water flow and increased tube , temperature in the hottest module. To evaluate this condition, a hot module analysis was performed using the HOT
MODULE code. The hot helium J
temperature transient was determined with the HOT
MODULE code using RECA region temperature and flow results as input. The points in the i

909269/A 4 RESULTS Table 4-1 presents the overall results from the computer codes including the Proto-Power pressure calculationn. The sequence of events for these cases was as follows:
1. A reactor trip occurs at 1 s into the transient, helium flow was camped to zero in 5 s, and feedwater flow was ramped to zero in 2 s. Both main cooling loops were shut down.

2. As a conservative assumption, the steam generator water pressure was assumed to be depressurized early in the transient. Beginning at 1 s into transient, the steam generator outlet pressure was ramped from normal 2600 psig to 250 psig or 75 psig in approximately 500 s.
3 A 75-min delay occurred with no feedwater or helium flow. 4 At 75 min into the transient, the water supply pump was assumed to be started, and the flow to the steam generators of one cooling loop was filled and ramped to full flow in 15 min.
5. The EES outlet water pressure was maintained via the main steam vent valve when venting to atmosphere, or LV-3250-2 and V-5288 when operating in the closed-loop configuration.

6. One helium circulator with Pelton wheel drive was started at i 90 min into the transient. At this time, firewater or condensate flow to the EES was at full flow.

7. Helium flow was adjusted to maintain the required water temperature at the EES outlet.

The operating points shown in Table 4-1 are from the transient performance at the peak temperatures. The results show that the EES cooldown can be performed satisfactorily within the head capability of the supply pump. The peak average steam generator helium inlet tempera-ture was 1406*F for EQ case,1391 *F for the Appendix R Train A case and 1394*F for the Appendix R Train B case. Peak fuel temperature was 2858'F for the EQ case, 2875'F for the Train A case and 2644*F for the Train B case. The peak hot module steam generator heliam inlet tempera-ture was 1501'F for the EQ case,1484'F for the Train A case, and 1489'F for the Train B case. Figures 4-1 through 4-5 present the transient results for the three EES cooldown cases at 87.55 and 83 25 power. Figure 4-1 presents the maximum fuel temperature, which shows the peak fuel temperature at about 5.4 h .into the transient for the EQ case, about 5.4 h into the transient for the Train A case, and about 4.5 h into the transient for the Train B case. Figure 4-2 shows the steam generator helium inlet temperature; Fig. 4-3 shows the helium flow required to maintain the required steam generator water outlet temperature; and Fig. 4-4 shows the primary system pressure. The pressure remains below the PCRV pressure relief valve setpoint throughout the transient for all cases. Figure 4-5 shows the steam generator inlet helium temperature for the average and hot modules.

5. CONCLUSIONS From the results shown in Table 4-1, it was concluded that a satisfactory EES cooldown can be obtained from 85% feedwater flow (87.5% power) with EQ equipment. A cooldown can be performed from approximately 80% feedwater flow (83.25 power) with Appendix R equipment for Trains A and B using an open loop for 5 h followed by a closed-loop arrangement for water supply (as specified in the Fort St. Vrain 10CFR50, Appendix R evaluation).
The pressure required to supply the water to the EES is within the capability of the condensate and the firewater pumps. Maximum core fuel temperatures and steam generator tube temperatures are within the allowable limits for these components. The hot module was maintained at subcooled water conditions for all cases. For the EQ cooldown the control setpoint at the steam generator exit was set at 255'F, for the Appendix R Train A cooldown the setpoint was set at 311 *F open loop and 368'F closed loop, and for the Appendix R Train B cooldown the setpoint was set at 257'F for open and closed loop to prevent Soiling at the steam generator outlet.

Dear Mr. Kennedy:
Enclosed is Proto-Power Calculation No. 82-03, Rev. B, dated ' December 15, 1986, "EES Safe Shutdown Cooling for PSC - Fort St. Vrain (3. Main Steam Vent Plow Path)". This calculation has been revised to evaluate fire water cooling through the main steam vent oatlet valve, throttled to maintain 76 psia pressure at PI-22129, with a steam generator outlet temperature of 257'F. As discussed in our meeting at PSC on December 12, this would be done in order to provide adequate subcooling on the average to accommodate hot modules and instru-ment error. The resultant flow rate is 948 GPM, with a pelton wheel flow of 125 GPM. Based on previous Proto-Power calcula-tions, this flow rate would be reduced to approximately 942 GPM with 175 GPM pelton wheel flow. j If you have any questions, please do not hesitate to call me at (203) 446-9725. Sincerely, MYp - Ap G. W. Geaney, Manager Engineering Services MJF: mas Enclosure cc: K. Dvorak-F. Tilson And A-2.

7511482 CUENT PROJECT M ECT EIS - MAIN STEAM VENT FLOW PATE PURPOSE To determine:
1. Fire water flow rate through EES Section of Steam Generator The flow path is through the new main steam vent valve , with 257'F sub-cooled water exiting the steam generator EES section, and 76 psia steam generator back pressure.
The overall flow path can be traced on the computer input file of Page 1 of Attachment A and depicted in the drawings that consti-
/ tute Attachment B.
METHOD ! The program described by Reference I was Qaed to calculate flow rates and pressure drops. i Furthermore, in order to determine the temperatures within the ! steam generators, another program developed by PPC was used. For ! this purpose, a primary coolant steam generator inlet temperature of 1400*F (approximately appropriate for 904 power conditions) was assumed, and primary coolant flow rate was adjusted to produce 257'F water at the steam generator outlet. The pressure at PI-22129 was controlled to 76 psia by throttling the main steam vent valve (reducing valve Cv in the input file), thereby assuring subcooled conditions throughout the flow path and in each EES module. The average temperatures within the steam generator are then entered in the input file (see Page 1 of Attachment A). These temperature values do not have a strong effect on the overall flow rate and pressure distribution. It was moreover decided that the asymmetry of the flow path (the vent lines coming of f one of steam generator outlet legs) would not produce noticeably dif f erent flow rates in each of the six l l f modules of one loop, since most of the resistance in the path is
\. constituted by the modules themselves. The flow path used for the input file is then representative.

Therefore, the pressure' drop is minor. Therefore, the pressure measured by PI-22129 should be just slightly higher than the pressure at PT. 200 ( 76 psia - see Attachment A, Page 2) ( REFERENCE ! 1.

Dear Mr. Niehoff:
Enclosed is Revision C to Proto-Power Calculation No. 82-12,
" Appendix R Safe Shutdown Cooling at X2 Power Level for PSC -Fort St. Vrain." This revision of the calculation supports heat removal quantities that will be identified in GA Technologies Report 909269, Issue A, for both open loop venting via the new main steam vents and closed loop heat removal using the decay heat removal exchanger.
The primary changes from the previous issue of this calculation (Rev. B) were to reduce the EES outlet temperature for Train A open loop flow to increase subcooling margin, and to correct a calculational error to both the open and closed loop Train B flow path. As a result, the calculated heat removal capacity of the Train A and Train B open loop flow paths have decreased slightly from those identified in GAT Report 909269 Rev. N/C, however, the closed loops are maintained at their previous value. The i enclosed calculations do not affect the previously calculated P2 power level of 83.2 percent. If you have any questions, please do not hesitate to call me at (203) 446-9725. Sincerely,

1. PURPOSE To determine the secondary cooling water flow rates and pressures through the two separate cooling water flow paths identified in Reference (A) for safe shutdown cooling following a major fire (10CFR50, Appendix R), modified to incorporate venting of the cooling water during the initial five hours of cooldown. Also, to determine the quantities of water (steam) vented during the cooldown and the avail-able water inventories.

2. BACKGROUND .
Two separate, alternate steam generator flow paths have been developed for safe shutdown cooling following a major fire, in accordance with the requirements of 10CFR50, Appendix R. A description of these flow paths, and their evaluation for compliance with 10CFR50, Appendix R can be found in Refer-ence (A). One flow path, Train A, is from one 12-1/2% condensate pump, through the EES section of one steam generator, the decay heat removal exchanger (for heat removal from the con-densate) and back to the condensate pump. The other flow path, Train B, is from the diesel-driven fire water pump, through the EES section of one steam generator, the decay heat removal exchanger (for partial heat removal from the fire water), the condensate storage tanks, service water return pump, the main cooling tower (for additional heat removal from the fire water) and back to the fire water pump. Secondary coolant flow rates for these flow paths were
evaluated in Reference (B). In an effort to increase the maximum power level for which the Appendix R shutdown flow paths could provide adequate cooling, the flow paths evaluated in Reference (B) have been modified to incorporate cooling water (steam) venting, via the main steam vents, during the initial hours of shutdown cooling, and thus increase the cooling water flow rate and decay heat removal.
! The procedure of venting during the initial hours of cooldown is consistent with the FSV FSAR, paragraph 10.3.2. Pcw a /4 &

Subsequent to that analysis, it became evident that the helium inlet temperature varied significantly from module to module, possibly causing the cooling flow in the hot module to boil. Iterative analyses were then performed by GA Technologies and Proto-Power to determine the required operating conditions to prevent boiling in the hot modules, account for instrumentation error, and to provide adequate core cooling from the X2 power level (also called the P2 power level). GA Technologies analysis, Reference (H), demonstrated adequate EES cooldown from the X2 power level with the following operating conditions: (GA Report No. 909269, Issue A, Table 2-1 [or as noted]) Train A Train B Venting Closed Loop Venting Closed Loop Flow, GPM 700 491 996 789 Inlet Temp.

Not in Table 2-1, but derived for this Calculation The above table was revised by GA Technologies in Reference (H) in accordance with Proto-Powers recommendation, to reflect an increase in sub-cooling margin for the Train A vented condition and to ensure the condensate pump would be operating in the performance curve range recommended by its manufacturer.

3. APPROACH The computer program and approach of Reference (B) were used to determine system pressure drop. The computer program "FSVSGNEW", Reference (C), was used to determine water temperatures within the steam generator. These temperature values do not have a strong effect on 'the overall flow rate and pressure distribution.
Decay heat exchanger performance was determined with the computer program HEATX, Reference (D). This program calcu-lates fire water outlet temperature and condensate outlet temperature. Condensate outlet temperature is also the inlet temperature of the steam generator for Train A. l The sections of the flow paths for Train A and Train B, and l associated hydraulic resistances are detailed on Attachments 5 and 6 (Drawing No. 7511482-PF-10, Rev. A& Drawing No. 7511482-PF-11, Rev. A, respectively). The anticipated cooldown scenario which was analyzed is as ! follows:
1. Vent to atmosphere until the closed loop heat removal capacity is adequate for shu'tdown cooling and any effects due to the " hot module" are acceptable. (Pelton wheel flow of 125 was assumed. )

2. Switch to the closed loop train per Reference (B), with no venting & a Pelton wheel flow of 175 GPM. Flow is then through PV-22153, with other system operating conditions as discussed in Reference (B).
The analysis proceeded as follows:
1. Open loop cooling water flow conditions through Train A were modified according to revised pump information, which had revealed that the maximum manuf acturer's guaranteed pump output is lower than first assumed.
Water flow, temperature, and pressure were iteratively Pc9 a A -/Y

l adjusted for both trains, in order to verify that heat l removal conditions and subcooling requirements stated in Tables 2-1 and 4-1 of GA Report, Reference (H),
could be satisfied, while operating on the pump's guaranteed performance curve.
2. Closed loop cooling water flow conditions through both trains were recalculated, considering that valve throttling would be necessary, so as to limit maximum .
attainable pressure in the area of the decay heat I removal exchanger. Parameters were adjusted to insure again that the conditions stated in Tables 2-1 and 4-1 of GA Report, Reference (H), could be satisfied.
3. Water quantities lost to venting for both trains were calculated based on a five hour venting period as stated in GA Report, Reference (H).
i 4. The maximum quantity of vented steam for each train was i then compared to the calculated available inventories of condensate and fire water.
4. RESULTS A. Detailed results of the evaluation are presented in Attachments 1 through 4 and 7, and are summarized below.
Previous issues of this calculation addressed two options for flow path venting, that is, either via the flash tank using HV-5252 or via the main steam vent. All X2 analysis in this issue of the calculation was directed exclusively to using the main steam vent flow path. Attachments 1 through 4 and 7 have been revised to confirm heat removal capacities summarized in Table 2-1 of GA Report, Reference (H). The changes from Revision A of Calculation 82-12 are as follows: Attachment 1 - The condensate water flow rate for the open loop Train A path is reduced from the original 939 GPM to 700 GPM. This change has been made to insure that the total flow is within the upper limit of the manuf acturer's guaranteed performance curve, which is 875 GPM. Steam generator output temperature was Pag e A~/9

Attachment 2 - Conditions have been rerun by Proto-Power to confirm the values estimated by GA Technologies for the closed loop Train A path. The results display a slight increase in cooling capacity from 491 gpm (listed in Table 2-1, GA Report Reference (B)) to 502 gpm, due to the use of the actual manufacturer's guaranteed performance curve, in lieu of an estimated curve. Pressure was throttled downstream of V-5288 to reduce operating pressure below the line safety valve set pressure of 175 psig. To provide a larger margin of subcooling in the above mentioned low pressure area, additional analysis was performed in Attachment 7. Steam generator outlet temperature was reduced from 368'F to 331*F, while maintaining the original 39' subcooling margin. Consequently cooling water flow rate was increased from 502 GPM to 669 GPM. The above conditions provided an increase in decay heat removal subcooling from 5'F to 27'F. An adjustment. in several valve positions vould be required. Attachment 3 - The fire water flow rate in the open loop Train B has decreased from 1058 GPM (Revision B of this calculation) to 996 GPM. This change is due to an error discovered in the flow resistance value of section 22-23 on Page 1 of this Attachment. The heat removal capacity has decreased accordingly. Attachment 4 - The fire water subcooling margin for the closed loop Train B has decreased from 72*F to 69'F as a result of the above mentioned error. Cooling water flow < rate was held unchanged at the expense of reducing the subcooling margin (by increasing the pressure drop). The revised subcooling margin of 69'F was determined to be adequate for this closed loop case, and greater than the Train A path, which would therefore be the power limiting path. ,i

Further, the condensate storage tanks are typically kept 40 to 50% full, although no technical specification requirement exists specifying minimum tank inventory. At 40% tank capacity, the available inventory reduces to 125,000 gallons which is significantly below the lost inventory for Train A.
