Dear Mr. Denton:

River Bend Station Unit 1 Docket No. 50-458 Gulf. States Utilities has performed analysis to determine the River Bend Station contalment pressure and tmperature response to deflagration type hy&upu burns resulting frun a degraded core-accident. Enclosed is a copy of GSU's report entitled "Contalment Pressure and Tenperature Response to Hydrogen Cmbustion".

We CLASIX-3 analysis used hy& @ source terms representative of severe accident conditions equivalent to a 75% clad equivalent metal-water reaction. As a result, the contaiment tmperatures and pressures predicted by this analysis are conservative.

W e peak containment pressure calculated by the CLASIX-3 analysis during hydrogen release was 20.3 psig and occurred in the intermediate volume. %is result, when cmpared with the RBS ultimate pressure retaining capability of 56 psig (GSU letter frm J. E. Booker to R. L.

Tedesco dated June 22, 1983) ds onstrates that hydrogen burns do not threaten the RBS containment structural integrity.

Gulf States Utilities is participating in the Hydrogen Control Owners Group (HCOG) testing and analysis program to further address hydrogen burn phenmenon. Results frm this program will be evaluated for applicability to the River Bend Station and incorporation into our final analysis, pg62;om m'@e I is A

Gulf States Utilities feels that the ccupletion of this analysis coupled with previous subnittals on the containment ultimate capacity analysis and the RBS Hydrogen Control System satisfy the hydrogen control rule requirements for a preliminary evaluation and provides a satisfactory basis for the staff determination to support interim operation at full power until our final analysis is empleted.

INTRODUCTIN

'No base case analyses have been performed to determine the River Bend Station (RBS) contalment pressure and temperature response to hydwgen release and subsequent deflagration due to degraded core events. These base cases were the stuck open relief valve loss of coolant accident (IOCA) and the drywell break IOCA, both with safety injection failure. Hydrogen generation rates obtained frcm a quasi-mechanistic core model were used along with RBS specific plant data as input to the CLASIX-3 cmputer code (Reference 1) . The intent of these analyses was to use, as much as possible, the same parmeters and assunptions used in the Hydrogen Control Owners Group (HOOG) sensitivity study (Reference 2) while factoring in more realistic assmptions based on a better understanding of degraded core phenomena.

sOuRCs Trams Stem and hydrogen releases were based on a quasi-mechanistic model so that the extensive oxidation required by the Hydrogen Control Rule (10CFR50.44) could be achieved. Previous analyses conducted under the auspices of the Hydrogen Control Owners Group (HOOG) using the BWR Core Heatup Code (BWBCHUC) have indicated that a mechanistic core heatup model with an intact core configuration cannot achieve the extent of oxidation required by the Hydrogen Control Rule.

Consequently, Gulf States Utilities has elected to use the 75%

metal e ter reaction hydrogen and stem release history developed by the HOOG.

f For the Stuck Open Relief Valve (SORV) base case, the initial 4

blowdown was obtained fran a River Bend Station specific analysis I using the MAAP cmputer code. Blowdown without core makeup was

! continued in this analysis for 2000 sec. at which time the core was I approximately 3/4 uncovered. At this point, the BWRCHUC, which l s ploys a mechanistic core model, was used to predict the hydrogen and 1

steam releases with 5 5000 gpn reflood timed to produce a 30%

i zirconitan-water reaction. '1his reflood occurred at 3400 seconds and i

i the BWRCHUC analysis was continued until 3645 seconds (HCOG Case "B" l history). During this boildown and reflood phase of the analysis, 436 4

l 1 lbn of hydrogen had been produced. Although the hydrogen release rate predicted by the BWRCHUC are above the threshold for diffusive type e

burning, we have conservatively asstuned that these releases only i produce deflagrations. At 3645 seconds a non-snechanistic model was

! used to obtain the ranaining 45% zirconium-water reaction. This model i

o developed by HCOG, uses an energy balance between the heat removal capability for a highly blocked debris bed and the core decay power,

. the heat of oxidation and the stored heat in the core material. 'Ihe non-mechanistic release rates were continued uncil a hydrogen release equivalent to 75% of the active core zirconium was reached as required

)-

! by 10CFR50.44. During this portion of the transient, the hydrogen release rate of 0.1 lbn/sec. produced a total of 1618.7 lbm of hydrogen.

For the drywell break base case (DWB), both the initial blowdown

- flow split between drywell and contairunent and subsequent hydrogen f

i releases were obtained fran the MAAP code. At 3645 seconds the same i

! non-mechanistic model as in the SORV case was used to calculate the l Page 2 e

i remaining hydrogen release history. For this portion of the transient, all hydrogen released (1,792 lbn at a rate of 0.1 lbn/sec.)

and stean flow (51 lbn/sec.) was conservatively assuned to enter the drywell.

MODEL A schematic diagram of the River Bend Station CIA 9IX-3 model used in this analysis is given in Figure 1. There are four carpartments in this model: the drywell, the wetwell, the intermediate volume, and the upper containment. We wetwell is defined to be the volume between the pool surface and the hydraulic control unit (HCU) floor. The intermediate volune is defined to be the volume between the HCU floor and the refueling floor. Also included in this model, is the l

! suppression pool and the hydrogen mixing system and the drywell bypass i

leakage. The model also included heat transfer correlations based on NUREG-0588 and drywell heat loads due to the reactor vessel and

?

associated piping. The arrows in Figure 1 represent flow paths between conpartments with the arrowhead pointing in the direction of i

allowed flow.

CASE DESCRIPTION i

Wo CIA 9IX-3 analyses were made for the River Bend Station. The input for these two cases are identical except for the quantity and location of the steam and hydrogen releases. In the stuck open relief L

! valve case, the releases enter directly into the wetwell side of the suppression pool over the entire transient. In the drywell break case the releases initially enter only the drywell. We autanatic depressurization systan is modeled to trip at Invel 1 which occurs at Page 3

1077.4 seconds. At his time the steam and hydrogen releases are split between the drywell and wetwell. During the initial boildown and reflood, the flow split between the drywell and wetwell were mechanistically calculated by using the MMP code. After the RPV reflood is empleted (3645 seconds), all releases are assumed to enter the drywell for additional conservatism. A bypass leakage equivalent to 10% of the allowable bypass leakage was also included in both the SORV and DWB analyses. In addition, heat loads to the drywell due to the reactor vessel and appurtenances were included in the analyses.

Heat transfer correlations based on NUREG-0588 were also included in the analysis.

Releases in both the SORV and DWB cases continue until hydrogen cquivalent to a 75% fuel clad (in the active core region) metal-water reaction is released frm the primary system. Both transients are continued after this time to evaluate the effect of the residual acctmulations of hydrogen.

NNIUPAL CIRCUIATION MODEL Natural circulation capabilities have also been incorporated into the CIASIX-3 cmputer program. In general, the containment response during hydrogen cmbustion is a three-dimensional, nonsteady, non-constant fluid properties prob 1m of cmpressible flow in which the buoyant force may be a significant contributor in the m mentum solution. Although pressure variations within a volume as a function of elevation are generally assumed to be negligible in a gas atnesphere, these variations becme important when considering natural circulation. Under these conditions, it is no longer possible to Page 4

assume uniform pressure throughout the entire containment as an initial steady state condition. With properly pwwmcd natural circulation, imposing an initial isobaric, isothermal condition on the contalment with volumes at different elevations will result in natural circulation to adjust the pressure distribution to account for the elevational differences due to the Rho-delta z term in the nnnentum equation.

In the model used in the CIASIX-3 program, it was assumed that the calculated pressure in the volume (either frm the perfect gas laws or the steam tables) applies to a single elevation in the cmpartment.

The elevation difference frm that point to the entrance to the flow path, the elevation difference in the flow path and the elevation difference frm the exit to the reference elevation in the exit volume were all considered. For true natural circulation, counter-current flow is also considered in all flow paths when appropriate.

For the present analyses, the reference pressure was assumed to exist at the vertical center of the volume. The vertical length of the flow path was conservatively assumed to extend only half of the distance frm the juncture of the two volumes to the plane of the reference pressure in each volume. For example, if two ten foot high volumes were situated one above the other with an opening between, the reference pressure would be at the five foot elevation above the floor in each volume. The flow path would extend 2.5 feet into each volume for a total flow path elevation length of five feet. This reptusentation of natural circulation is appropriate and conservative.

INPUT IN MPMATION The input parameters are specific to River Bend Station but in many cases are similar to those used in the CLASIX-3 analyses subnitted by the IICOG.

The steam and energy release to the suIpression pool for the SORV base case are given in Table 1. 'Ihe steam and energy releases to the drywell and suppression pool for the DWB base case are given in Figure

3. Hydrogen releases for the SORV and DWB base cases are given in Tables 2 and 4, respectively.

The burn parameters for this analysis are consistent with all previous CLASIX-3 analyses and the HOOG sensitivity study (Reference

2) . The hydrogen volume fraction required for ignition is 0.08. The hydrogen volume fraction required for propagation of a ' urn is 0.08.

The fraction of hydrogen burned is 0.85. The minimui oxygen volume fraction required for ignition is 0.05. The minimum oxygen volume fraction required to support cmbustion is assumed to be 0.0. These hydrogen burn parameters were used for conservatism even though tests done at the Nevada Site indicate that the hydrogen volume fraction for propagation is approximately 0.06 and the fraction burned is closer to 0.65 percent. Calculated burn times are 6.34 seconds for the drywell, 2.00 seconds for the wetwell, 6.02 seconds for the intermediate volume and 11.67 seconds for the upper containment based on a flame speed of 6 ft/sec.

Parameters for the cmpartment initial conditions are given in Tabic 5. These include net free gas volumes, tmperatures, and oxygen, nitrogen and steam partial pressures. Partial pressures were Page 6

calculated frm empartment tmperatures, pressures, and relative humidities assuming the containment atmosphere consisted of a mixture of steam and standard air.

The maximum flow area, flow loss coefficient, and burn propagation delay time for the drywell to intermediate, wetwell to intemediate, intermediate to containment flow paths are given in Table 6. The intermediate to drywell flow path represents the hydrogen mixing systm inlet line. The drywell to intermediate flow path represents the drywell bypass leakage.

Table 7 gives the suppression pool parameters, including the initial pool water density, mass, tmperature and heat capacity.

Gemetry related pool parameters are the nutber of vents, the vent flow area, length of each vent, the subnergence depth to the bottm of the vent, the turning loss coefficients, the gas loss coefficients and the additional vent lengths to account for fluid acceleration. The pool surface areas in the drywell and wetwell are also included. The weir height above the normal or equilibrium water level and the drywell holdup volume and surface area are input parameters for the analysis of reverse flow through the suppression pool.

The River Bend Station design utilizes a contalment unit cooler systm instead of a spray systs to assist in reducing containment tmperatures and pressures. The servica water supplying the unit coolers is assumed to be at the maximum design value of 95 F; therefore the unit coolers are ineffective in reducing containment air tmperature below 95 F. At an ambient tmperature of 185"F, the systm renovos 6388.9 Btu /sec of heat. Therefore, the unit coolers are modeled as a constant tmperature heat sink that rmoves heat Page 7

l based on a linear ramp up frcra 0 Btu /sec at an ambient air tcrperature of 95 F to a maximum of 6388.9 Btu /sec at an ambient air tmperature of 185 F. Above an ambient air temperature of 185 F a constant value of 6388.9 Btu /sec is used. The unit coolers are initiated intnediately 1

following the first burn.

l Structural passive heat sinks are conservatively modeled in the analysis. These heat sinks include platfonns, gratirvy, concrete walls and floors and steel walls and floors. Data on passive heat sinks is given in Table 8 through 12. he passive heat sink modeling is conservative since heat sinks due to equipnent, piping, etc. are neglected. W e radiant heat transfer bean lengths are based on PBS specific gecmetry considerations and containment dimensions. The radiant heat transfer beam lengths are given in Table 13. Convective heat transfer correlations are based on NUREG-0588. For additional conservatism, the outer surface of the free standing contairunent is assumed to be adiabatic.

The drywell heat loads are given in Table 14. These heat loads am due to the reactor vessel and main steam /SRV piping.

RESULTS A suninary of the results of the two River Bend Station cases is given in Table 15. Tcmperature and pressure information is given in Figures 2 through 13 for the SORV (stuck open relief valve) case and Figures 30 through 42 for the EMB (drywell break) case. Plots of the volume fractions of oxygen, hydrogen, nitrogen, and steam are shown in l

Figures 14 through 29 for the SORV case and Figures 43 through 58 for the DWB case.

%e results of the SORV case will be discussed first. During the first 3645 seconds of the transient, 3 burns ignited in the wetwell at l a hydrogen concentration of 8 voltzne percent (v/o) . %e first two of l these burns resulted in wetwell tanperature peaks of approximately 1200 F. The third burn resulted in the highest wetwell tarperature peak (2135 F) for the entire transient. This burn occurred at approximately 3400 seconds which corresponds to the peak hydrogen

! release. All subsequent hydrogen burns resulted in tarperature peaks l

i of approximately 1200 F.  !

After the initial blowdown and high hydrogen release, a series of 39 burns occurred in the wetwell. Each burn in this series was of .

about the sarne magnitude in tarporature (1200 F) . We time interval I

between burns was approximately 5 minutes. After hydrogen release was terminated, a concurrent burn was forced in the wetwell, intermediate volume, and contairunent. This forced burn was the only burn that occurred in the intennediate voltane and contairinent. The peak testperature in the intermediate voltane and contairment as a result of the forced burn was 1084 F in the intennediate volume and 1154 F in l

the upper containment. After the forced burn, the available hydrogen l was insufficient for canbustion and the transient was tenninated.

l During hydrogen release, the maxh.un calculated pressure of 7.3 I psig occurred in the wetwell volume. Maximum pressures of 3.3 psig, l 6.3 psig and 6.3 psig were reached in the drywell, intermediate i

voltane, and upper containment respectively. Following the hydrogen release, maximum pressures of 12.3 peig, 24.3 psig, 24.3 psig and 24.3 psig were reached in the drywell, wetwell, intermediate volume, and upper containment, respectively, due to the forced hydrogen burn. As Page 9 i __ - _ _ . . . - _-_ ._

E l

with the torrperatures resulting frcm the forced burn, these pressures are artificial in that the hydrogen concentration in the containment I

was well below the ignition criteria even though a global burn was l

forced to occur.

At the end of the transient, 38 lin of hydrogen renained in the drywell, 17 1hm ranained in the wetwell, 24 lbm in the intermediate l voline and 6 lin in the containment. Since minimal concentrations of hydrogen romained, the transient was terminated. A total of 1986 lbn l

of hydrogen was constned during the transient.

During the period of hydrogen release for the DhB case, all 28 burns ignited in the wetwell at a hydrogen concentration of 8 v/o.

Since there was insufficient hydrogen or oxygen in the drywell throughout the transient, there were no hydrogen burns in the drywell.

% e total hydrogen burned during the hydrogen release was 1416 lin.

%ere were no hydrogen burns in the intermediate volume or contairment during hydrogen release since the hydrogen concentration was always below the ignition criteria. During the first 6000 seconds of the transient, a single burn occurred in the wetwell resulting in a peak tarperature of 1893 F. This peak corresponds to the peak hydrogen release. During the remainder of the transient, a series of regularly spaced wetwell burns occurred with peak tanporatures of 1300 F.

Following the hydrogen release, a concurrent burn was forced to occur in the wetwell, intermediate volume and upper containment. tis forced burn resulted in tarperatures of 341 F,1137 F,1039 F, and 1154 F in the drywell, wetwell, intermdiate volino and upper contairnent respectively.

Page 10

We maxinun calculated pressure of 20.3 psig occurred in the wetwell during hydrogen release. We drywell, intermediate volume and upper contairinent reached maxinun pressures of 19.3 psig,17.3 psig, and 16.3 psig, respectively, during the hydrogen release. At the end of the transient, the wetwell, intermediate volume and upper contaiment had hydrogen concentrations of approximately 6.5 v/o.

%ese empartments were forced to ignite in spite of their hydrogen concentrations being below the ignition criteria. Wis resulted in pressure peaks of 32.3 psig, 45.3 psig, 44.3 psig, and 45.3 psig in the drywell, wetwell, intermediate voltano and upper contalment respectively. Again, these results are artificial in that a global hydrogen burn was forced to occur. At the termination of the transient, 31 lbn of hydrogen reained in the drywell, 9 lbn in the wetwell, 24 lbn in the intermediate voitune and 10 lbn in the upper containment. A total of 19801hn of hydrogen was consumed during the transient.

SLM%RY For the two River Bend cases analyzed, the peak calculated contaiment pressure during hydrogen release was 20.3 psig, and brief duration tmportture peaks ranged frm 388 F in the drywell to 2135 F in the wetwell to 640 F in the intennediate volume. No hydrogen burns occurred in the drywell, intermediate volume or upper contalment during hydrogen release for either the SORV case or the DWB case.

l

! Since there were no burns in the drywell, the peak tmperature of i

388 F was due to steam / hydrogen release and flow of hot gases frm the i

intonnediate volume. Likewise, the peak intermediate volume and upper l

[

Page 11

l i

contalment tmperatures during hydrogen release were due to flow of I hot gases. The tmperature in the intermediate volme remained below 300 F for the entire transient excluding a few short duration peaks.

When burns were forced to occur at the end of the transient, the J

intermediate volume tmperature reached 1084 F and the maximum upper contalment taperature was 1154 F. 'Ihe forced burns also produced a q peak pressure of 45.3 psig due to artificially forcing a concurrent wetwell volme, intermediate volme, and upper contalment volme i

4 burn. However, calculated results for these forced global burns are j highly conservative and do not represent realistic hydrogen release s

and catustion phenomena.

The results of this analys.is provide estimates of the contalment 4

pressure and tmperature response to deflagration type burns. 'Ihe hydrogen release rates used in this analysis are consistent with the requirements of 10CFR50.44 and the release rates proposed under Task 7

! of the liCOG Program Plan (Reference 3). The results of this analysis provido a conservative estimate of the contaiment pressure and taperature response to deflagration type hydrogen burning.

! As part of task 12 of the llOOG Program Plan, HOOG will demonstrate

{

l that CLASIX-3 conservatively predicts containment peak tmperatures I

and pressures. When cmpleted, the results of these IICOG tasks will be evaluated for applicability to River Bend.
