I'. Introduction Pre-test analyses were performed using the TRACG code, to simulate the conditions of-four tests to be conducted at the GIRAFFE facility (Ref.1) by TOSHIBA Corporation at Kawasaki, Japan and predict the results of these tests. A schematic of the test facility is given in Figure 1. The model used in the TRACG simulations was originally developed by TOSHIBA and was extensively modified at GENE to represent the conditions of the
. System Interaction tests (SI tests). This set of calculations is part of a validation effort for the TRACG code for application with the SBWR.
As described in the TAPD (Ref. 2), the test objective of the series of four SI Tests is to provide a data base to confirm the adequacy of TRACG to predict the SBWR ECCS performance du-ing the late blowdown /early GDCS phase of a LOCA, with specific focus on potential systems interaction effects.
A series of four tests are planned and will have initial conditions approximately 10 minutes post-LOCA. The duration of the tests will be approximately 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br />. The containment related parameters will be based on the corresponding SBWR TRACG LOCA case at the time the RPV pressure is 1.034 MPa. The basis for the tests is described in the TAPD (Ref 2, Table A.3-23). A brief description of each test is given below:
- 1. Test GSI, the base case, is a GDCS line break with one DPV failure and no PCC or IC operation. This set of test conditions resulted in the lowest predicted chimney level.
. 2. Test GS2 is the same as GSI except that the PCC and IC are operational during the
. test. Test results can be compared with GSI for potential systems interactions associated with the IC and PCC.

- 3. Test GS3 is a bottom drain line break with a single DPV failure. Here again the IC and PCC will be operational. This test would represent the case with the fastest water level recovery.
- 4. Test GS4 is a GDCS break with a failure occurring in a GDCS valve in one of the other two GDCS lines. The IC and PCC will be operational in this case as well. This test is expected to give the slowest rate of re"ery of the chimney swollen level.
- 2. TRACG Model The TRACG model consists principally of a three dimensional component, known as the VSSL (vessel) component. Various parts of this component contain the models for the Reactor Pressure Vessel (RPV), the Suppression Chamber (SC), the Upper Dry Well (UDW), the GDCS pool, the PCC pool and the IC pool. The remainder of the components including the Annular and Lower Dry Well are modeled using one dimensional components. A schematic of the nodalization of the VSSL component is presented in Figure 2.
A list of 1-D components, consisting of VLVEs(valves), PIPES and TEES is given in Table 1. The differences between the SBWR nodalization and the GIRAFFE nodalization are presented in the next section.
2.13-D Vessel Component The VSSL has 22 levels (axial divisions),3 rings (radial divisions) and one azimuthal sector. This essentially represents three isolated 3-D regions: levels 1-10, levels Il-16 and levels 17-22. The true physical differences in the elevation of these three regions are determined by the heights of the 1-D components that connect them. Within the first 3-D region, ring I represents the RPV. The SC is represented by levels I through 7 in rings 2 and 3. The UDW is represented by levels 9 and 10 in ring 3. In the second 3-D region, levels 1I through 16 in ring 3 represent the GDCS pool. The PCC pool occupies rings I and 2 and levels 1I through 16. The IC pool occupies the third 3-D region and consisting of levels 17 through 22. The remainder of the space in the VSSL component is not used.
Heat transfer to the ambient is possible in TRACG only from the outermost ring and thus the SC, UDW and GDCS pool all have heat losses to the ambient modeled with doubic-sided heat slabs. In the RPV, the walls are represented by lumped heat slabs.
2.2 RPV Internals The RPV portion of the vessel contains three 1-D components to represent the channel, guide tube and bypass regions (GTBP) and the chimney. TRACG allows for a special l-D component (actually a TEE component) to represent a fuel bundle and the present model represents the heater rod assembly by CHAN08. There are five cells in the channel component. The GIRAFFE RPV internals are shown schematically in Figure 3. The GTBP is modeled using TEE 34. As depicted in Fig. 3, the heater rod region is surrounded I

by the GTBP. In the TRACG model, the leak path into the GTBP from the channel is represented by the side junction of CHAN08 and TEE 34. In addition CHAN08 exchanges thermal energy with TEE 34, thus representing the GIRAFFE geometry very closely. The top of CHAN08 connects to TEE 16, the chimney and the top of TEE 34 connects to the side branch of TEE 16 (see Fig. 3). The chimney and the GTBP have five cells each. Both TEE 34 and TEE 16 exchange heat with the fluid in the RPV (3-D) component. The bottom of CHAN08 and the top of TEE 16 are connected to the 3-D RPV component. The heated length in the channel component is 2.44 m long and extends from 0.76m from the RPV bottom to 3.2m.
2.3 RPV Piping VLVE40 represents the drain line from the bottom of the GDCS pool to the RPV (see Figs. I and 2) and enters the RPV at im above the top of active fuel (TAF). VLVE52 represents the vessel end of the broken GDCS line for the GSI, GS2 and GS4 cases.
VLVE55 represents the bottom drain line break in GS3 and extends from the RPV bottom to the LDW. VLVE43 and VLVE44 are also connected to the RPV and represent the Isolation Condenser (IC) steam supply line and the drain lines respectively. VLVElI represents the Automatic Depressurization System (ADS) opening. All the 1-D components ofimportance are shown in one or more of Figures 1,2 and 3.
2.4 Dry Well, Suppression Chamber and GDCS Piping The LOCA vent line is represented by PIPE 06 and has a submergence of 1.6m below the SC water level. The drywell end of this line is located at the bottom of the UDW. There will be Dow through this line only when the DW pressure exceeds the SC pressure by more than the hydrostatic head corresponding to the vent submergence in the pool. The Vacuum Breaker line (VBL) between the SC and the DW is VLVE07 and opens or closes based on set points-the valve opens when the wetwell pressure is 3240 Pa higher than the DW and it closes when the pressure difference is less than 2060 Pa.
PIPE 30, TEE 31, TEE 37 and TEE 32 represent the Annular DW and the LDW with the top of PIPE 30 connected to the bottom of the UDW. The GDCS break line,VLVE51, is connected to annular DW as is the other end of VLVE52. In test GS3, the BDLB line, VLVE55, is connected to the LDW. The Passive Containment Cooling System (PCCS) steam supply line is connected to the top of the UDW and is represented as VLVE03.
There is also an pressure equalization line(VLVE41) between the GDCS and the DW.
The vent lines from the IC and PCC are connected to the SC. The PCC vent line, VLVE05, has a submergence of 0.85m. The IC vent line, VLVE45, is physically represented in the model, but is not used in the tests. The PCC drain line,VLVE04, connects to the GDCS pool.

The two systems occupy different pools and are made up of three 1-D components each.
Each system consists of a steam box, a heat exchanger and a water box for the condensate. The GIRAFFE facility consists of three heat exchange tubes, each of length l.8m in the PCC and 2.4m in the IC. All three tubes are operational in the PCC whereas only one tube is operational in the IC All these features are modeled in TRACG using TEES-TEEL 4, TEE 10 and TEE 15 in the PCC and TEE 17, TEE 18 and TEEL 9 in the IC.
The PCC and IC heat exchangers transfer heat to their respective pools.

Heat losses to the ambient in the RPV are not modeled as the TRACG model does not allow heat transfer to the outside from inner rings in the VSSL component (the RPV is bounded radially by ring 1 of the VSSL component). Heat losses to the ambient are modeled for the GDCS pool, the DW and the SC. This is accomplished by the use of a double sided heat slab model in TRACG. The outside film resistance and insulation are combined into an effective heat transfer coefficient which is specified together with the ambient temperature. The heat losses in the SI Tests were not measured directly but were inferred from the Helium tests (Ref. 3). By simple extrapolation it was determined that these losses were not sufficiently different for the two test series. Thus, the net heat loss parameters (heat transfer coefficient or heat transfer area) from each component was adjusted to be the same as in the Helium tests.
2.7 Decay Heat The decay heat curve for each test was determined by scaling down the SBWR values by a factor of 1:400.
Unlike in the previous tests, the heat losses were not compensated for by increasing the heater power. This would perturb the conditions of the test by introducing additional heat into the lower RPV, thus affecting the minimum level in the chimney. Tables 2 through 5 contain the appropriate initial power at the start of each test. The power in the heater rods is adjusted to produce the decay heat and an average of 8 kW over the first 200 secs representing stored energy in the channel, cladding and heater rods.
2.8 Initial Conditions The initial amount of water in the RPV for each test was determined by scaling down the total mass of fluid contained in the SBWR RPV by a factor of 1:400 and adding 0.7 m as margin, as specified in the test specifications. All flows into and out of the RPV were also scaled down by a factor of 400. The initial mass of wate"in the drywell and flow rates
were scaled by 1:400. The various temperatures and pressures for the four tests are given in Tables 2 through 5. The initial RPV pressure for all four tests is 1034 kPa and the GDCS pool water is in a subcooled state.
Microheaters were used to compensate for the heat losses in the DW, SC and GDCS pools. However, this was not sufficient to account for the heat losses in the DW (including LOCA vent) and the GDCS pool. There were no microheaters for the RPV.
The net loss of heat for the RPV, DW and GDCS pool were approximately 8 kW,12 kW and 7 kW respectively. The SC heat losses were fully compensated for.

3.0 COMPARISON TO THE SBWR NODALIZATION Ideally, the nodalization for the GIRAFFE model should be similar to the existing SBWR nodalization. However, there will be differences related to the differences in physical configurations. The nodalization is similar in the upper DW, WW, and PCC which are considered crucial to the purpose of the GIRAFFE SI tests. A brief one on one comparison is best shown in tabular form.
Component GIRAFFE SBWR RPV VSSL - 10 levels VSSL - 16 levels I ring 4 rings GDCS pool VSSL - 6 levels VSSL'- 2 levels I ring 3 rings PCC pool VSSL - 6 levels VSSL - 6 levels 2 rings 2 rings IC pool VSSL - 6 levels VSSL - 6 levels 2 rings 2 rings WW VSSL - 7 levels VSSL - 3 levels 2 rings 3 rings DW Upper VSSL - 2 levels VSSL - 3 levels I ring I rings Annulus 1 - D, 9 cells VSSL - 4 levels in 3 components I rings Lower 1 - D, 4 cells VSSL - 1 level 4 rings PCC tubes 1 - D, 8 cells 1 - D, 8 cells IC tubes 1 - D, 8 cells 1 - D, 8 cells Channel 1 - D, 5 cells 1 - D,21 cells Chimney 1 - D, 5 cells VSSL - 4 levels 3 rings
The GIRAFFE RPV has one ring compared to four rings in the SBWR. It is felt that the one ring design is sufficient to model the RPV flow since TEE 34 models the guide tube and bypass regions along with two leak holes between it and the channel. Three additional levels were added at the bottom to the RPV model (compared to the GIRAFFE He test model) as minimum levels could reach those regions during the course of some of l
the SI tests and thus a finer level scheme was required to capture some of these effects.
As a result of this, the SC also added three levels at the bottom making it a 7 -level 2 -
ring model. The annular DW had to be broken up into three 1-D components to accommodate various breaks that needed to be modeled.
- 4. Discussion of the Test Simulation Results 4.1 Test Results Results for the four tests are plotted in Figures 4-41. The set for test consists of the RPV, DW and SC pressures, the downcomer and chimney levels, the GDCS flow and the integrated mass from the vacuum breaker. In addition, the pressures and levels are shown in more detail in plots for the first ten minutes of the experiment. In GS2-4, the PCC and IC inlet flows are also shown.
4.2 Test GS1 As described in Section 1, this test was run with no IC or PCC in operation. It starts at a RPV pressure of 1034 kPa, at which time the ADS valves (except the I failed DPV) are opened to start the blowdown phase of the experiment. The water level in the chimney swells to about 5 m above the top of active fuel (TAF). In about three minutes, the pressure has fallen to about 300 kPa. The dry well, meanwhile pressurizes initially as a result of the blowdown but as the RPV-DW pressures equalize and the ADS flow stops (about 200 secs), the pressure drops as a result of the cold water that is continuing to pour in from the broken GDCS line. The driving head for the GDCS exceeds the RPV pressure at about 100 secs and the GDCS flow starts, quenching the voids in the RPV and collapsing the two phase level in the chimney to about 1.0 m above TAF. The level then recovers and continues to climb as a result of the GDCS flow. It reaches the top of the chimney at about 1600 secs and does not drop below this for the remainder of the test. At about 500 secs, the level reaches the broken GDCS line in the RPV ( l m above TAF) and flow starts from this line into the DW. As the water level in the RPV rises beyond the inlet point of the GDCS, the flow from the GDCS starts to drop as a result of the decreasing driving head.
The GDCS break flow to the DW is turned offin the test after about a third of the water volume in the GDCS pool is exhausted to simulate the fact that in the SBWR each of the three GDCS lines originates from a separate pool. This happens at about 3100 sec, after
1 which the DW pressure slowly increases. The'RPV water level reaches a maximum at about 2600 secs (see the downcomer level plot) and remains there till the GDCS flow stops at about 5900 secs. The level then starts to drop at this point and continues to do so till the end of the test.
During the period from about 200 see -500 sec, the vacuum breaker opens a few times as the DW-RPV pressure drops below that of the WW. The breaker also opens and closes over a period of 600 secs starting at about 600 secs and to much lesser extent between 1700 and 2700 secs.
The test was designed to simulate a worst condition in the RPV 'where the water level drops to its lowest point. The TRACG simulation indicates that even in the absence of the PCC and IC, there is no threat of core uncovery during the GDCS phase of a blowdown where these minimum levels are expected to occur.
4.3 Test GS2 This test is very similar to GSI except that the IC/PCC systems are active. The behavior of the RPV and containment is similar to GSI. In these tests, however, there is return flow from the IC back to the RPV up to about 1300 secs. The swollen chimney level reaches about 6m above TAF and the minimum level, which occurs at about 200 secs, is about 2.0 m above TAF ( about 1.0 m in excess of GSI). This difference between GS1 and GS2 can be attributed to the flow back to the RPV from the IC. The level then tecovers and reaches the top of the chimney at 1500 secs (about 100 secs before GSI).
The RPV-DW pressure profile and the interaction with the WW is similar to GSI. The downcomer level also behaves like it does in GSI. The GDCS flow continues up to 6200 secs, longer than in GSI because of the flow back from the PCC into the GDCS pool.
t The flow into the IC ends at about 1500 sec. The PCC flow is very small, except for the first 200 secs, till about 4700 see when it begins to pick up as the PCC inlet flow is once i
l again established.
Overall, the effects of the IC and to a smaller extent, the PCC, are observed in this test.
j' The lowest chimney swollen level is higher and the level recovers to the top of the chimney about a 100 secs earlier than in GSI.
i 4.4 Test GS3 This test has the lowest depressurization rate of all the tests and the fastest level recovery.
The minimum level is at 3.8 m above TAF and the level recovers to the top of the l-chimney at around 900 secs. The GDCS flow starts at about 120 secs and the flow rate drops more rapidly than in the other tests due to the more rapidly diminishing driving head. The downcomer level reaches the ADS flow opening and the level lingers around I
this point for the rest of the test. The IC and PCC behavior is similar to the previous test.
I
The GDCS flow continues to the end of the test since there was no break in any of the GDCS lines in this test. Around 2500 secs there is two phase flow out of the DPV line into the DW. By about 4500 secs, as the RPV level fluctuates about the DPV opening, there is periodic venting of steam into the DW increasing the GDCS flow. The flow periodically rises and falls. Eventually, as the GDCS pool level starts to approach that of the RPV, this effect becomes more pronounced, with GDCS flow dropping close to zero periodically.
Test GS3 shows, as expected, the fastest chimney level recovery of all the tests.
4.5 Test GS4 This test is very similar to GS2 except that the failure is a GDCS nozzle instead of a DPV valve. Since this test has the lowest amount of GDCS flow, the chimney level recovery is the slowest. The minimum water level is about 2.0 m above TAF and it occurs at about 200 secs. The time of level recovery to the top of the chimney is about 2000 secs. The RPV-DW pressure is slightly higher than in GS2. The IC and PCC behavior is very similar to GS2.
As expected, this test shows the slowest level recovery.
4.6 Conclusions The four tests show results as expected and indicate that the even in the absence of the IC l
and PCC the core will not uncover during these worst case breaks. The IC and PCC show the interaction of these systems with the vessel and containment have the effect of increasing the minimum chimney levels attained during these transients during the GDCS phase.
