Th;s report represents the general part for all DataTransmittal Reports (DTR) related to the l

PANDA SBWR Test Program.

i Abstract PANDA is a large-scale thermal-hydraulic low-pressure test facility for investigating passive decay heat removal systems for the next generation of Light Water Reactors. In the first instance PANDA is used to examine the long-term LOCA response of the Passive Containment Cooling System (PCCS) for General Electric's Simplified Boiling Water Reactor (SBWR). The PANDA SBWR Test Program general objectives and the test matrix for the facility characterization, and the PCC steady-state and transient system tests, are given in this report.

l PANDA is a modular representation of the SBWR containment compartments and passive decay heat removal system. Overall scaling is 1:25 (volume, power, horizontal area) while i

relevant vertical heights are maintained 1:1. Process fluids, pressures and temperatures are prototypical. Facility key figures are 515 m* total vessel volume, 25 m height,1.5 MW l

maximum power and 10 barg /180*C maximum design operating conditions. Auxiliary systems allow proper test conditions to be set. The facility is controlled with a PLC (Programmable Logic Controller) system, which is govemed by a PC-based graphicai display MMI (Man / Machine Interface) with on-line data visualization. The report includes a description of the facility configuration and a scaling summary as well as a summary of the fa:ility characterization tests.

More than 600 sensors have been used for measuring temperatures, pressures, pressure differences, levels, flow rates, gas concentrations, fluid phases and electrical heater power.

The measurements are sampled with an integrated data acquisition system which includes data conversion to engineering units. Data are forwarded to a workstation-based storage system which provides capabilities for on-line and off-line time-history representation of measurements. Data are ultimately transferred to the PANDA Experimental Data Base. The report provides a description of the measurement equipment and systems (including a detailed instrumentation list) and the structure of the PANDA Experimental Data Base.

Finally, a summary of representative standard and upper bound measurement errors is given.

1. Introduction i-l

1.1 Background

In 1991 the Paul Scherrer Institut (PSI) initiated the experimental and analytical programme ALPHA (Advanced Light Water Reactor Passive Heat Removal and Aerosol Retention i

Programme). Part of this programme is PANDA, a large scale thermal-hydraulic low pressure test j

facility for investigating passive decay heat removal systems for the next generation of Light Water Reactors (LWR). In the first instance PANDA is used to examine the integral long term -

performance of the Passive Containment Cooling System (PCCS) for the Simplified Boiling Water l

Reactor (SBWR).

l The SBWR is an evolutionary design in boiling water reactors (BWRs) and has been developed by an intemational design team from North America, Europe, and Asia and led by the General l

Electric Company (GE). The design extensively uses the technology of operating BWRs, as well as new developments found in the Advanced BWR (ABWR). A key feature of the SBWR is the use of simple passive systems to respond to any type of design basis event (DBE). These systems utilize passive forces, such as gravity heaa, natural circulation, or pressure differences, to operate.

t One of these systems is the Passive Containment Cooling System (PCCS). The SBWR containment is similar to existing BWRs which have the reactor in a drywell region. The drywell is connected to a wetwell through submerged pipes in the suppression pool, a part of the wetwell.

The PCCS consists of three Passive Containment Condensers (PCC) connected to the upper l~

drywell gas space. During a postulated loss-of-coolant accident (LOCA) the mixture of steam and noncondensable gases present in the drywell is driven into the PCCS by the pressure difference i

between the drywell and wetwell. The condensate flows into the Gravity-Driven Cooling System j

(GDCS) pools in the drywell. The GDCS is an another SBWR passive system which provides makeup to the reactor. Noncondensable gases, such as containment nitrogen, are separated in

('

the PCC and vented to the wetwell through submerged pipes in the suppression pool. All piping i

on the PCCS contain no valves, which results in a completely passive operation.

i 1.2 PANDA Facility i

PANDA is a large-scale integrated SBWR containment test facility that is located at PSI. The facility is an approximately 1/25 volumetric, full-scale height simulation of the SBWR containment system. PANDA has a modular structure. Pressure vessels representing the Reactor Pressure Vessel (RPV), Drywell (DW), Wetwell (WW) and wetwell air space, and GDCS pool are i

interconnected with appropriate piping in order to simulate a variety of containment transients.

i The facility is equipped with three scaled PCC heat exchangers and one Isolation Condenser (IC) unit, each with its own water pool. The PCC and IC units are both scaled by holding the heat transfer tubes at full size, but reduced in number from the prototype. The reactor pressure vessel l

volume is equipped with electrical heaters to simulate decay heat and thermal capacitance of the l

vessel and internals. The scaling of the facility is generally based on the SBWR design as it was in December 1992. The facility is capable of simulating SBWR accident scenarios starting l

approximately one hour into the LOCA.

I In addition to its transient capabilities, PANDA also has temporary piping connections such that a PCC heat exchanger may be tested in a quasi steady-state manner.

2. Test Program General Objectives t

l and Test Matrix The test program includes the facility characterization tests, the PCC steady-state tests and the transient system tests. The general objectives and the test matrix are given below.

l 2.1 Facility Characterization Tests l

The objective of these tests was to obtain data about leak rates, heat losses and system line pressure losses of the PANDA facility to confirm that the design requirements for the facility were met. In addition, some of these data have been used as inputs to code calculations. The main results are summarized in chapter 6.

2.1.1 Leakage Tests The test program includes a series of cold air leak tests. The objective of the cold leak tests is to determine the leakage rate of individual vessels to other vessels and the atmosphere. The initial conditions and the criteria for completion of the tests are specified in the vessel cold leak test plan and procedure [2.1].

2.1.2 Heat Loss Tests The objective of the heat loss tests is to determine the temperature dependent heat losses of the individual vessels (including the appertaining piping) to the ambient. The initial conditions and the criteria for completion of the tests are given in the heat loss and system lines pressure loss test plan and procedure (2.2].

2.1.3 System Line Pressure Loss Tests The objectives of the tests are:

- ensure that the PANDA system lines pressure drop is adequately simulating the SBWR line loss characteristics

- obtain data about pressure drop versus flow rate for the individual system lines.

The initial conditions and the criteria for completion of the individual line loss tests are given in the heat loss and system lines pressure loss test plan and procedure [2.2).

2.2. PCC Steady-State Tests l

2.2.1 Test Program Objectives l

The objectives of the PCC steady-state tests were to provide additional data to:

1 (a) support the adequacy of TRACG to predict the quasi-steady heat rejection rate of a PCC heat exchanger, and (b) identify the effects of scale on PCC performance.

. - ~.-

s a

ALPHA-606-0 / Page 14 l-The approach to achieve these objectives was:

(a) measure the steady-state heat removal capability with various inlet air mass fractions for steam flows approaching the PCC design rating.

l i

(b) perform counterpart PCC condenser tests to those run at PANTHERS and GIRAFFE.

j 2.2.2 Test Matrix l

A series of steady-state tests was conducted using one of the PCC condensers (Table 2.1). The facility was configured as described in Section 3.3 to inject known flow rates of saturated steam l

and air directly to the heat exchanger. The condenser inlet pressure was maintained at 300 kPa for all tests with air flow by controlling the wetwell pressure. The pool surface elevation in WW2 was low relative to the PCC3 vent line exit elevation. The steam and air flow to the heat j

exchanger were controlled and measured. in addition, the condenser drain flow and vent flow were measured when the magnitude of the flow was high enough to be measured with the flowmeters. Four tests were conducted with various air flows and a constant steam flow of 0.195 l

kg/sec (S2 to SS) and pressure of 3 bar. In addition, two tests with no air flow were run (S1 and S6), one with the same steam flow as for the steam / air tests (S1) and one with a greater steam g i

flow (S6). For these tests with no air flow, the PCC3 vent was closed and the pressure was 3 allowed to seek its own level. The test S10, S11 and S12 are repetitions of S3, SS and S6,

{-

respectively. Test S13 is a repetition of S12, but with the PCC pool level lowered to the bottom of the upper PCC header.

4 i

Tests S7 through S9 were declared as non-valid tests.

2.3.1 Test Program Objectives The test objectives of the PANDA integral system tests were:

1. Provide sufficient database to confirm the capability of TRACG to predict SBWR containment system performance, including potential systems interaction effects. (Integral l

Systems Tests) 4 j

2. Demonstrate startup and long-term operation of a passive containment cooling system.

. (Concept Demonstration) i i

2.3.2 Test Matrix-l Table 2.2 provides the test matrix overview in the order that the tests were performed. The following gives the objective and additional descriptive information on each transient system test:

- Test M3 is the base case test. It is a simulation of a break in the main steam line of the j.

SBWR. The nominal initial containment conditions were similar to those calculated for the SBWR under SSAR assumptions at one hour into the LOCA. The initial drywell pressure i

was approximately 300 kPa. One-half of the steam from the RPV was directed to DW1 which has one PCC condenser, and the other one-half of the steam was directed to DW2 with two PCC condensers. This was achieved with separate blowdown lines from the RPV to each of the two drywells. The two blowdown lines have essentially equal flow resistances.

I These Test conditions represent a symmetrical situation in the PANDA facility. The PCC

]

i.

pools were hydraulically interconnected but isolated from the 10 pool. This Test provides a j

base case for comparison to all other Tests.

- Test M3A and M38 were run with the same test conditions and the same test configuration as those for Test M3, except for the PCC/lO pools. These two tests were run to i

demonstrate transient system response repeatability for the base case Test M3 while investigating altamatives for the PCC/lO pool configuration and filling. These tests fulfill the I

objective of PANDA Test M4 as defined in (2.3] and have been substituted for Test M4.

j I

- Test M3A was run with the PCC/lO pools hydraulically isolated from each other and 1

periodically refilled to maintain the pool levels.

j

- Test M38 was run with the PCC/lO pools hydraulically interconnected and periodically refilled to maintain the pool levels.

- Test M7 was initiated with the drywell and PCC units filled with air at the start of the transient. The heater power remains constant throughout the test. The PCC pools were isolated for this and all subsequent tests and no water was added during the test. This test provides data to demonstrate the PCC condenser startup.when initially blanketed with noncondensable gas and the drywell nonconcensable gas concentration is the maximum value possible.

- Test M2 is a repeat of Test M3 but, with all of the break flow directed into DW2. DW2 has two PCC condensers. This test maximizes the steam content of DW2 and the air content of DW1. The Test M2 results can be compared with test M3 results to quantify asymmetric effects on PCCS containment performance.

- Test M10 was identified in [2.3] as a Test "...to be defined later, utilitizing the experience gained from the previous tests'. After running Tests M3, M3A and M3B it was determined that this test should investigate bounding conditions for noncondensable gas transfer from j

the drywell to the wetwell. To do this, two Tests (M10A and M108) were defined to be run j

with only the two PCCs on DW 2 in operation.

- Test M10A is an asymmetric case with all the break flow directed into DW2. Only the two PCC condensers from DW2 are connected to the system. Therefore, DW1 has no direct inflow of steam from the RPV and no direct outflow to the PCCs. This test provides data showing the noncondensable gas migration from DW1 to DW2.

- Test M10B is an asymmetric case with all the break flow directed into DW1. Only the two PCC condensers from DW2 are connected to the system. This test provides data showing the bounding conditions for noncondensable gas transfer from DW to WW with only two PCC's e

operating.

e

- Test M6/8 is a repeat of Test M3 with the isolation Condenser (IC) operating in parallel with the three PCC condensers throughout the first six hours of the test. This period provides data showing the interaction between the PCC condensers and the IC, as well as the effect of the additional heat removal by the IC on containment and reactor system performance. Four hours after test initiation the DW1 to WW1 bypass leakage line was opened. This bypass area of ten

. -. _ -... _. - ~

times the scaled SBWR technical specification value remained open until the end of the ten hour test. This part of the test provides data showing the effect of bypass leakage on containment performance. The combined effects of IC operation and bypass leakage are 4

shown during the overlapping two hours.

I This one test satisfies the objectives for Test M6 (interaction between the PCC condensers and the IC) and Test M8 (effect of pypass leakage) as defined in (2.3].

- Test M9 starts at LOCA plus 1040 seconds whereas all the other M-series tests are initiated at LOCA plus 3600 seconds. The specific objective of M9 is to perform a test with conditions l

simulating the transition from the GDCS injection phase to the long-term PCCS cooling phase of the post LOCA transient.

j

- Test M5 was deleted. This test as described in [2.3] was to investigate the effect on PCC j

performance of reintroduction of noncondensable gas to the drywell from the wetwell airspace r

via the vacuum breakers. The vacuum breaker opening was to be achieved by drywell spray actuation to reduce drywell pressure. Subsequent to the conduct of tests M3A, M3B and M9 i

which all had vacuum breaker openings due to PCC pool subcooling or GDCS flow into the RPV, it was determined that no additional PANDA data with vacuum breaker operation was necessary.

3. PANDA Test Facility Description j

3.1 General Description PANDA is a large scale thermal-hydraulic low pressure test facility for investigating passive decay heat removal systems for the next generation of Ught Water Reactors. In the first instance PANDA was used to examine the long-term LOCA response of the Passive Containment Cooling System (PCCS) for the General Electric Simplified Boiling Water Reactor (SBWR). According to the general design guide lines PANDA has a modular structure. The complex volumes of containment compartments, decay heat removal systems and other SBWR components are represented in PANDA by a system of interconnected cylindrical vessels, heat exchangers, condensers, pipes and valves. Section 3.2 describes the main components of the facility in greater detail. Besides transient system test also component tests such as PCC steady-state i

tests will be performed N 'ising only a portion of the complete facility. Section 3.3 describes the configuration for the s%y-state tests.

{

'The facility is designed to exhibit thermal-hydraulic behavior similar to SBWR under LOCA conditions beginning approximately one hour after scram. The global volume scaling of the facility l

is approximately 1:25. The elevation scaling of 1:1 has been applied to the parts of the system I

which are above the top of the SBWR core. The SBWR components which are modeled in the facility are: the Passive Containment Cooling System (PCCS), the Isolation Condenser (IC) l System, the Gravitiy Driven Cooling System (GDCS), the Reactor Pressure Vessel (RPV), the j -

Drywell (DW), the Wetwell (WW) and the connecting piping and valves. Electrical heaters provide l

a variable power source to simulate the core decay heat and the stored energy in the reactor structures. Rigorous geometric similarity between SBWR containment volumes and test facility I

vesseis is not necessary to capture the fundamental features of the containment response and has not been attempted.

l The PANDA vessels are connected with scaled piping components to represent the connecting lines in the SBWR. The test facility vessels, the piping connections and valves are shown schematically in Figure 3.1. The arrangement, elevations and volumes of the major vessels are shown in Figure 3.2.

The SBWR RPV is simulated by a vessel containing electrical heaters. The top of the heaters is at a relative elevation which represents the top of the active fuel (TAF). With the RPV simulator partially filled with water the heaters will generate steam which is discharged to vessels representing the SBWR drywell. The drywellis represented by two vessels connected by a large i

diameter pipe. The wetwell is also represented by two vessels. The bottom of the wetwell vessels

)

are filled with water to the same relative elevation above TAF as the SBWR suppression pool.

l-The wetwell vessels are connected by two large diameter pipes, one in the gas space and one Just below the water surface. The purpose of using two connected wetwell/drywell vessels is to L

permit a simulation of multi-dimensional or asymmetric conditions (temperature, gas fraction).

The PANDA facility includes three scaled PCC units and one scaled IC unit (representing the scaled capacity of two SBWR 10 units). These are mounted above the drywell vessels at the same elevation above the TAF as in SBWR. Two of the PCC units are connected to one of the 1

drywell/wetwell vessels and the third PCC is connected to the other drywell/wetwell. The IC unit is 1

connected to the simulated RPV. All four condensers are submerged in water in tanks l

representing the PCC/IC pools. Figure 3.3 shows the IC/PCC condenser test units.

The SBWR GDCS pools are represented in PANDA by a single GDCS vessel. The elevation of the GDCS vessel is representative of SBWR, but the volume of the GDCS vessel is not scaled the same as other PANDA vessels. It is not necessary to scale the volume of GDCS water in order to model the part of a SBWR LOCA transient tested, because the GDCS tanks primary function during the time period tested is to act as a collection tank for the PCC condensate drain flow.

l The transient tests are conducted at temperatures and pressures representative of SBWR postulated LOCA conditions after initiation of the GDCS. To assure these conditions can be tested in PANDA, the facility has been designed to 10 bar an:11800 C. These conditions exceed i

l SBWR LOCA conditions after initiation of the GDCS.

l l

The key facility characteristics and their as-built accuracies are summarized in Section 3.4. The l

facility design and as-built drawings are included in the PANDA Test File (PTF, Sections 2.1 and

(

3.1).

l The PANDA scaling summary,is presented in Section 3.5 of this report.

(

3.2 Component Description 3.2.1 RPV The PANDA vessel used to simulate the RPV is cylindrical with a nominal outside diameter of l

1.25 m, a height of 19.2 m and a nominal volume of 22.8 m3. The vessel is scaled to the SBWR RPV volume above the bottom of the reactor core, as discussed in more detail in Section 3.5.1.

The simulated decay heat power to the test facility is provided by electrical heaters placed near the bottom of the RPV The top of the heaters is at the same relative elevation as the top of the active fuel (TAF) in the SBWR. The elevation of the RPV bottom is 1.5 m below TAF A cylindrical sleeve inside the RPV is used to represent the SBWR core shroud and chimney (riser). The outside diameter of the riser is 1.066 m.The steam separators and dryers are not simulated because they have no significant effect on the long term release of steam to the containment.

The PANDA heaters have an installed maximum capacity of 1.5 MW. The scaled decay heat power of the SBWR at one hour after scram is 1.056 MW. The remaining power can be used to simulate the RPV intemally stored energy release.

The RPV heater bundle consists of 115 heater elements. The bundle is subdivided into six groups. Four groups are on/off controlled, that means each group is able to deliver either 0 or the nominal power of 300 kW. The remaining two groups together have variable power output between 0 and 300 kW. The power control system combines these two types of groups to accurately follow any given energy release transient within the limitations of the installed capacity.

Change over of power from one on/off group to the variable groups (or vice versa) takes no longer than ten seconds. Consequently whenever it is necessary to replace an on/off group by the variable groups a maximum power deviation of +/ 300 kW occurs for a maximum time period of ten seconds. This happens, based on the scaled decay heat curve, no more than two times during a 20 hour2.314815e-4 days <br />0.00556 hours <br />3.306878e-5 weeks <br />7.61e-6 months <br /> (or shorter) transient system test. The maximum possible error with respect to the integral energy release caused by the group switching is less than 0.02 %

3.2.2 Drywell l

The SBWR drywell is represented in the PANDA facility by two cylindrical vessels connected by a large diameter pipe or duct. The vessels are designated as "DW1' and 'DW2". Each of the two i

vessels has an outside diameter of 4.0 m, an inside height of 8.0 m and a nominal volume of i

l

~

=_.

l ALPHA-606-0 / Page 23 90 m3. The connecting pipe between the drywell vessels has a volume of 3.5 m3 and an inside diameter of 92.8 cm. The total volume of the PANDA drywell has been scaled to the SBWR upper and annular drywells,i.e. it does not include the lower drywell region. The elevation of the PANDA DW bottom corresponds to the SBWR DW main floor. Access to the inside of both drywell vessels has been provided by man holes.

l 3.2.3 Wetwell The PANDA facility has two connected vessels to represent the SBWR wetwell. The wetwell vessels ac designated as "WW1" and "WW2". The two vessels are cylindrical with an outside diameter of 4.C m, an inside height of 10.1 m and each with a nominal volume of 117 m3. Each vessel is partially filled with water to represent the SBWR Suppression Pool (SP). There are two large horizontal pipes connecting the wetwell vessels; one in the gas space above the water level (inside diameter of 92.8 cm and volume of 2.7 m3) and one just below the normal water level NWL (inside diameter of 142 cm and volume of 6.3 m3). Wetwell vessel WW1 is directly below and provides support to drywell vessel DW1. Vessels WW2 and DW2 are similarly arranged (see Figure 3.2). Access to the inside of the wetwell vessels has been provided similar to the drywell access.

The wetwell vapor space was scaled to preserve the pressure response of the trapped noncondensable gas in combination with steam. The total wetwell pool surface area is scaled to correctly represent the evaporation / condensation processes at the pool surface.

The pool water depth extends sufficiently below the PCC vent line terminus to provide a representative volume of water with which the uncondensed steam vented into the suppression pool can mix. The suppression pool depth is large enough to cover the topmost LOCA (horizontal) vent and the wetwell to-RPV equalization line. However, the total depth of the pool is reduced j

from the depth of the SBWR suppression pool by elimination of the region P.t the bottom of the SBWR pool which does not participate in the long term mixing. The wetwell bottom corresponds to TAF.

3.2.4 PCC Condenser Pool /IC Pool The PANDA facility represents the PCC/lO pools with four rectangular tanks (with outside dimensions of 2 m x 1.5 m) mounted above the drywell vessels at an elevation above the top of the RPV heaters the same as the bottom of the SBWR IC/PCC pools are above the core TAF.

The height of the tanks is 5 m, which allows for prototypical pool level. The pools for the four condensers can be either isolated or interconnected below the bottom of the pool to allow free passage of water and maintain the same hydrostatic water head in each compartment. An auxiliary system provides demineralized water to the pool prior to a test and also drains the pool when needed for maintenance, modifications or repairs.

Steam generated in the pool during testing is vented to the surroundings which maintains the pool surface at atmospheric pressure. The pool tanks are sized to provide sufficient water to keep the condenser tubes covered for approximately 20 hours2.314815e-4 days <br />0.00556 hours <br />3.306878e-5 weeks <br />7.61e-6 months <br /> under the assumption that all four pools are interconnected and initially at saturation temperature. A water supply is available to refill the pool with cold water either from the bottom or from the top during the course of an experiment. The pool walls are insulated to limit the heat loss to that associated with net vapor generation.

i l

3.2.5 GDCS Pools The three SBWR GDCS pools are represented by a single tank in the PANDA facility. Since l

PANDA was designed to model SBWR long-term cooling performance following the initiation of

{

r ALPHA-606-0 / Page 24 i

GDCS injection (i.e. LOCA + 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br />), the GDCS tank is not scaled to the full GDCS volume of SBWR (1:64 instead of 1:25 scaling).

The PANDA GDCS tank is a cylindrical vessel with an outside diameter of 2.0 m, an inside height of 6.06 m and a nominal volume of 17.6 m3. The bottom of the PANDA GDCS tank is at the same elevation as the bottom of the PANDA drywell and is the same elevation above the TAF as the l

SBWR. During a transient test, the tank collects the condensate from the PCC units and returns it i

to the RPV.

3.2.6 PCC Condensers The three SBWR PCC condenser units are represented in PANDA by three condenser units scaled 1:25 for the number of tubes and header volumes and scaled 1:1 in tube height, pitch and diameter. This provides a heat transfer surface area of 1:25 of each SBWR unit. Each of the PANDA PCC units has 20 tubes welded at the top and bottom to headers having the same diameter as the SBWR units. Each of the three units is a slice of one module of a two-module SBWR unit. This scaling is expected to ensure that secondary side behavior of the PANDA condenser unit is representative of the SBWR units. Since the PANDA condensers are only small (

segments of the SBWR condensers, side plates have been added to guide the flow through the tube bundle in a manner t,imilar to that expected in a complete condenser. Each PCC unit has a

&flector plate in the upper header to avoid flow maldistribution in the down stream flow bundle.

Tne PANDA PCC units are shown in Figure 3.3.

One of the PCC units (PCC1) receives steam / air mixture from DW1, vents to WW1 and drains the condensate to the GDCS tank. The other two units (PCC2 and PCC3) receive inlet flow from DW2, vent to WW2 and drain the condensate to the GDCS tank. One PCC unit, PCC3 has been constructed so that it can also receive steam directly from the RPV in order to test the steady-state performance of the condenser (see Figure 3.4).

3.2.7 isolation Condensers The SBWR isolation condensers are represented in PANDA by a single condenser unit, similar in design to the PANDA PCC units. The PANDA IC is scaled 1:25 to the capacity of two of the three SBWR units (each SBWR IC unit reprs; ants 50% capacity, only 100% is simulted in PANDA).

The PANDA IC has 20 tubes of full height and diameter with prototypical spacing. Side plates guide the secondary flow outside the tubes to make it similar to the secondary side behavior of (he SBWR units. As in the PCC units, a deflector plate is installed in the 10 upper header. The PANDA IC unit is shown in Figure 3.3.

The PANDA 10 unit receives steam or steam / air mixture from the simulated RPV and retums condensate to the same vessel. Small vent lines can discharge noncondensable gas from the upper and lower headers of the IC to WW1.

3.2.8 Top LOCA Vents The SBWR LOCA vents are represented in PANDA by two 100 mm diameter pipes, one from each drywell to the suppression pool of the corresponding wetwell tank. The drywell end of the vent is connected at the wall of the drywell vessel, near the bottom. The pipe enters the side of the wetwell tank, near the top of the gas space, and then tums 90-degrees downward and ends b6lcw the surface of the suppression pool. The pipe is submerged to a depth equivalent to the top of the uppermost SBWR LOCA vent. This line only allows flow from the drywell to the wetwell when the DW to WW pressure difference exceeds the hydrostatic head corresponding to the LOCA vent submergence. The pipe diameter is smaller than the ' scaled" diameter (greater flow l

ALPHA-606-0 / Page 25 resistance) but is not a concern because the submergence is the important parameter, not the vent resistance.

3.2.9 Vacuum Breaker and Bypass Leakage Path The three SBWR drywell-wetwell vacuum breakers are mounted in the diaphragm floor which j

separates the upper drywell from the wetwell gas space. This flow path is simulated in the i

PANDA facility by a pipe from near the bottom of the each drywell to near the top of the i

corresponding wetwell. The vacuum breaker valve itself is simulated by control valves in each of i

these two pipes. The valve controllers are programmable so that the differential pressure controls the opening and closing of the two vacuum breaker valves. The wetwell to drywell differential pressure at which the vacuum breaker for Drywell 1 opens is set at -3.24 kPa, and the differential j

pressure at which the vacuum breaker for Drywell 1 closes is set at -2.06 kPa. The opening and closing differential pressure for the vacuum breaker in Drywell 2 is set 0.1 psi lower than the corresponding setpoints for the Drywell 1 vacuum breaker, i.e. at -3.9 kPa and 2.8 kPa, respectively [3.3). The same setting is used for all transient tests except test M9, where the setpoints for VB1 and VB2 are the same as for VB1 in the previous tests.

The PANDA vacuum breaker discharge into the drywells is directed vertically downward, toward the bottom of the drywells. The distance from the discharge elevation to a flat, horizontal deflector plate is similar to the distance between the SBWR vacuum breaker discharge elevation and the diaphragm floor which is 0.25 m. The deflector plate is large enough to remove the vertical momentum of the discharge and redirect the flow horizontally. The flow area is sized such that the horizontal flow velocity is of the same order as the SBWR velocity.

The overall p assure drop for the vacuum breaker lines is scaled per the methodology described in(3.1].

A simulated wetwell/drywell leakage path is provided by a bypass line with a valve around each of

' the two simulated vacuum breaker valves. Effective bypass leakage areas can be varied by changing the size of an orifice in the bypass line and the bypass flow measurement system.

3.2.10 Other System Piping The PANDA piping which simulates the significant SBWR piping is scaled to provide prototypical pressure losses for the scaled PANDA flow rates. The scaling is generally based on the SBWR design as it was in December 1992. Detailed information about scaling of the system lines is given in [3.1). The following piping is scaled:

PCC Piping: Each of the three PCC condenser units has an inlet line, a condensate drain line, and a vent line.

1 Isolation Condenser Piping: The isolation Condenser unit has a steam inlet line, a condensate retum line, and a line, which is not properly scaled, for venting noncondensable gas from both the upper and lower headers.

GDCS Lines to RPV: A pipe is provided to drain water from the GDCS pool tank to the simulated RPV.

Main Steam Line: Piping is provided to carry steam from the RPV to the drywell, representing six SBWR depressurization valves (DPV) or one broken SBWR main steam line and five DPVs.

Equalizer Line: Piping representing the SBWR equalizing line has been provided between i

the bottom of the wetwe!!s and the simulated RPV.

l

ALPHA-606-0 / Pags 26 3.2.11 Auxiliary Systems Piping The primary purpose for these lines is to supply or/and drain steam, water, and air to and from vessels and tanks in order to achieve the proper initial test conditions (temperature, pressure gas concentration). Under certain circumstances, specified in the test procedures, these lines may be incorporated into the actual tests.

j 3.3 Steady-State Unique Test Configuration i

l The steady-state PCC tests are run with a different hardware configuration than that used for the transient tests. As shown in Figure 3.1 and Figure 3.4, a pipe is installed to deliver steam directly j

from the RPV to PCC3. Air is injected into this line downstream of the steam flow measurement locaiion. The drywell tanks play no part in these tests, so they are isolated. The pressure in the 1

l GDCS tank and the wetwell tanks are equalized through an auxiliary steam line. The PCC3 drain line is open to the GDCS tank and the GDCS tank drain line is open to the RPV. The check valve i

in the GDCS tank drain line is removed. The PCC3 vent line to the wetwell (WW2) is not g submerged in water in order to better control the pressure at the PCC3 upper header. For all tests 4 the PCC3 steam supply line is insulated as shown in Figure 3.4.

3.4 Key Facility Characteristics Table 3.1 identifies the l(ey PANDA facility geometry and the system line effective flow area j

( A/[i) characteristics. The required tolerance for the PANDA as-built value relative to the corresponding SBWR scaled value is tabulated for each of these key characteristics (3.3]. In addition, the required accuracy for the as-built value for each of the key characteristics is given in Table 3.1. The actual as-built accuracy is equal to or less than the required accuracy. The actual as-built accuracies depend on the source of the as-built value. These sources are measurements j

by PSI or Elektrowatt (i.e., line losses, line iengths, elevations), manufacturer's specifications or design standards (i.e., PCC/lO tubes), or calculations from as-built dimensions (i.e., vessel volumes, losses for lines without flow tests).

The dimensions of all the facility componen s (vessels, condensers, system lines etc) can be found in the PANDA test file (PTF Sections 2.i and 3.1).

IC vent and LOCA vents are not scaled to SBWR 3.5 Scaling Summary The scaling approach and a detailed analysis of the scaling based on the as-built dimensions for the PANDA test facility are presented in the scaling report NEDC-32288, Section 4.3 (3.2].

The scaling of the facility conforms to the top-down and bottom-up criteria developed in the report montioned above. Full vertical heights and submergences are preserved to correctly represent the various gravity heads; volumes are represented at the system scale. The exceptions to these are noted below. The experiments will be conducted under reactor pressure and temperature conditions which are prototypical for the phase of the accident under consideration.

ALPHA-606-0 / Page 31 3.5.1 Volumes Figure 1.1 shows the geometrical arrangement of PANDA in comparison to the SBWR and the relative elevations of the two systems. All the SBWR heights are represented except those below-the Top of Active Fuel (TAF) in the core. The top of the PANDA RPV electrical heaters is placed at the TAF location; however, the heaters are about 1/2 the height of the SBWR core.

In the RPV, the liquid inventory above the Bottom of Active Fuel (BAF) is scaled according to the system scale of 1:25. The liquid inventory below BAF in the RPV was eliminated, since it remains saturated and essentially inactive during the post-LOCA phase of the accidents considered, and is not required for the correct simulation of gravity heads. However, the liquid volume between mid-core and BAF is included in the scaled PANDA RPV volume by a small adjustment of the vessel diameter. The lowest SBWR line simulated in PANDA is the equalization line which enters the RPV at one meter above TAF. Thus, eliminating and redistributing the water volume Lelow mid-core and modifying the length of the heater elements will not significantly influence any natural circulation paths for the portion of the post-LOCA transients simulated by PANDA.

The PANDA RPV includes a downcomer and a riser above the heater rods which represent the reactor core. The flow areas in the downcomer, the riser, and the core are scaled according to the top-down criteria (areas proportional to the system scale). The PANDA riser has no vertical partitions; its diameter is close to the hydraulic diameter of one partition of the SBWR riser. There is no representation of the steam separators and dryers, because liquid entrainment and RPV to DW pressure drop are insignificant for the portion of the post-LOCA transients simulated by l

PANDA.

f The lower part of the water inventory in the suppression pool (SP) was eliminated to reduce vessel size; this water will not participate in the system thermal-hydraulic transient during the long-term cooling phase of the accidents considered indeed, the important phenomena will take place above the submergence depth of the PCCS vents. The PANDA PCCS vent lines are submerged in the SP with about 2.85 m clearance above the bottom of the SC vessel, so that the i

reduced depth of this vessel will not influence venting of the noncondensables. Effects such as the convection of water to the bottom of the vessel by cold plumes running down walls are of i-minor importance.

}

The water is approximately 2 m deep below the main vent submergence in PANDA, which is l

sufficient to accommodate any mizing during the accident phase simulated in this facility. The l

effect of deeper mixing during t,owdown in the SBWR is simulated by proper adjustment of the j

test initial conditions.

4 The lower part of the annular DW volume surrounding the RPV was not included in the height of j

the PANDA DW volume, since it was felt that possible natural circulation phenomena taking place l

in this annular volume (heated on one side by the RPV) could not be adequately simulated. The volume of this annular space was, however, added to the PANDA DW volume.

t l

The lowest part of the SBWR DW volume (the region below the RPV support skirt and pedestal) is not included or added to the PANDA DW volume. Indeed, the lower DW volume provides only a j

' repository" for noncondensable gas or water. The water inventory in the lowest part of the DW is i

significant only from the standpoint of producing long-term evaporation which could carry j

noncondensable gas to the upper DW and counteract the tendency of the noncondensables to sink to the bottom of the DW.

The GDCS compartment volume scale (1:64) is smaller than the system scale (1:25). This volume j

does not play an important role in the dynamics of the system; in the transients considered, it i

simply provides a retum path for the condensate to the RPV. The GDCS volume is sufficient for l

containing the water inventory one hour after the LOCA. The scale of the horizontal surface area l

I 6

c-

ALPHA-606-0 / Page 32 I

of the GDCS pool is also smaller (1:64) than the system scale. Thus, while any tendency of the steam to condense on the surface of the GDCS pool water will be reduced, this will also lead to a slower heatup of the GDCS water, in terms of overall energy removal, the net effect is not significant.

Finally, the total volume of the IC/PCC pools is smaller than the total SBWR pool volume; these are scaled for 20 hours2.314815e-4 days <br />0.00556 hours <br />3.306878e-5 weeks <br />7.61e-6 months <br /> of decay heat capacity, rather than 3 days, as in the SBWR. However, water can be added at a required flow rate by the facility conditioning system to compensate for the lesser initial inventory.

3.5.2 Scaled Models of the PCC and IC Condensers The PANDA condensers are " sliced' from the prototypes. Thus, the circulation of the secondary coolant in a plane perpendicular to the axis of the cylindrical headers can be made very similar to that in the actual SBWR condenser pools. The units are provided with baffles, preventing entry of the flow into the bundle in the direction of the header axis. A sufficient number of tubes was provided to have at least a couple of tubes completely surrounded by other tubes. This led to five rows of tubes, twenty tubes in total, and to the 1:25 system scale in PANDA, condenser tubes (

are in all respects (height, pitch, diameter, and wall thickness) prototypical.

3.5.3 Design of the Piping and other Connections The system lines are scaled to match the frictional and form losses of the SBWR; the resulting pipe diameters were rounded to the next larger normalized diameter. The actual pressure drops are usually dominated by form losses which depend weakly on flow velocity (or Reynolds number) and can thus be matched very well. Alllines are provided with interchangeable orifice plates that can be used to further adjust the pressure losses in the system.

The two PANDA main steam lines are scaled to match the frictional and form / losses of the SBWR MSLs and the DPVs. Valves are installed in each line (one to each DW) to establish either symmetric or asymmetric flow from the RPV to the drywells.

The vacuum breakers, which provide the flow path for potential redistribution of noncondensable gas between the SC and the DW, are simulated by programmable control valves which can reproduce the characteristics of the corresponding SBWR components. Tne VB discharge lines in the DW are scaled such that outlet flow velocity and flow direction are similar to the SBWR.

The vertical-pipe sections of the main vents have a cross-sectional area smaller than the one dictated by the system scale. However, the key parameter establishing whether or not flow occurs j

in the main LOCA vent lines is the submergence of the vents in the suppression pool. The gas velocities in the main vents are, in both the prototype and the model, low enough to eliminate worries about dynamic effects modifying system behavior, if the vents were to clear.

4. Instrumentation 4.1. General Requirements The test facility has sufficient instrumentation to measure all parameters needed to achieve the test objectives defined in Section 2. All test instrumentation is calibrated as necessary against traceable standards, i.e. the Swiss Federal Office of Metrology or equivalent.

The following sections cover all the instrumentation which is used at PANDA for steady-state and for transient tests.

4.2 Instrumentation Identification System The identification system for the PANDA instrumentation employs the PANDA identification code.

This is composed of three strings, which are separated by a point.

< type >. < designation >. < extension >

< type > addresses the function of an identified item (cf. Table 4.1), < designation > refers to its location, which is expressed in terms of vessel or pipework designations (cf. Table 4.2), and

< extension > is typically a counter, which allows items with otherwise identical type and designation to be distinguished. The syntax is:

CAA d6A.AA where 'C' stands for a character, 'A' for an alphanumeric symbol; underlined positions are mandatory. Hence, an identification code has a minimum length of four symbols and a maximum length of ten.

Based on this identification code, PANDA measuring instruments with electronically recordable output are identified by a < type > string starting with 'M'. For a measurement identification the second symbol in the < type > string is also mandatory and specifies the measured quantity, (e.g.

'T' stands for temperature, 'P' for pressure, etc.). The third position is used to further specify the measured quantity, e.g. partia! pressures or different types of temperature measurements. For valve position recordings, the < type > string defines directly the valve (e.g. CC and CB for control and on/off valves, respectively).

Exceptions to this nomenclature are 'MO' for the Vacuum Breaker trigger signal < type >, and a simple double digit string 'ij' for the reference temperature < designation >, where i and j indicate, respectively, the extender and the slot number.

4.3 Instrumentation Description l

l The PANDA test facility has the capability to measure the following physical parameters:

temperatures, mass flow rates, pressures, pressure differences, liquid levels, gas concentrations, fluid phases, valve positions and electrical power. PSI document [4.1) defines the ranges expected for the various parameters to be measured. Table 4.3 provides a list of all the instrumentation available on the PANDA facility together with the key characteristics of each instrument including, in addition to the system instrumentation, the instrumentation of the auxiliary systems. The accuracies given in Table 4.3 represent the standard errors according to Section 8 of this report. While in Table 4.3 a short description of the measurement location is given, the detailed description and the as-built documentation of the instrument locations are given in references [4.2] for Temperatures and Gas Concentre.tions in Vessels, Condensers and Pools, in

[4.3] for all Pressures, Pressure Differences and Levels, and in [4.4) for the System Lines Instrumentation. Table 4.4 gives a summary listing of the total number of sensors of each type.

The following provides an overview of the measurement capability in the facility.

4.3.1 Temperature

{

Most temperature measurements in the PANDA facility are made with inconel-sheathed type K (Chromel-Alumel) thermocouples. The reference junction temperatures are measured with thermistors.

The following fluid temperatures are measured with type K thermocouples:

- in the gas and liquid regions of vessels,i.e.

- RPV drywells and connecting line between drywells

- wetwells and two connecting lines betwee7 wetwells GDCS pool

- in the liquid regions of IC/PCC pool liquid surfaces temperature in DW's, WW's and GDCS pool in the system lines,i.e.

lines from the RPV to the drywell and the IC lines from the drywell to the PCCs LOCA vent lines PCC vent lines

- 10, PCC and GDCS drain lines

- vacuum breaker and vacuum breaker leakage lines between the drywells and wetwells

- wetwell/RPV equalization lines

- in the upper and lower headers of the IC and the PCC units

- inside some of the tubes in all four condensers.

In addition metal temperature measurements are taken with type K thermocouples:

along the length of some of the IC and PCC condenser tube walls on the walls of key vessels and system lines.

ALPHA-606-0 / Page 69 Platinum resistance (Pt100) temperature measuring devices with Contrans T TEU 421 amplifiers manufactured by Hartmann & Braun are used to measure the fluid temperature at all flow rate measurement locations.

4.3.2 Flow Rate 1

l Flow rates in PANDA are measured with four different types of flow measuring devices.

5 Three ultrasonic flow meters (System 990 Uniflow model manufactured by CONTROLOTRON) are used to measure the volumetric flow rate at any three of the following locations:

- the PCC drain lines to the GDCS

- the GDCS drain line to the RPV

- the IC drain line to the RPV f

- the equalization line between the suppression pool and RPV.

Ten vortex flow meters (Vortex PhD-90S model manufactured by EMCO) are installed in PANDA to measure the volumetric flow rate at the following locations:

- the main steam lines the IC and PCC supply lines

- the PCC vent lines

- the water supply line to the RPV or to the water auxiliary system A small vortex flow meter (Swingwirl 11 model manufactured by Endress & Hauser) is used to measure the flow in one vacuum breaker bypass leakage line.

A hot film flow measuring device (Sensyflow VT2 model manufactured by SENSYCON) is used to j

measure the air mass flow supplied to the PANDA facility by the auxiliary air system.

4.3.3 Pressure Pressures throughout the PANDA facility are measured with Rosemount model 3051CA,2088A, and 1144A pressure transducers.

Pressure transducer are installed at the following locations:

-in the RPV in the drywell vessels

- in the wetwell vessels (gas space)

- in the IC and PCC upper headers (at the inlet flow measurement location) in the GDCS tank

- the atmospheric pressure at all steam / gas flow measurement locations.

1 ALPHA-606-0 / Page 70 4.3.4 Pressure Difference Pressures differences throughout the PANDA facility are measured with Rosemount model 3051CD and 1151DP transducers. Transducers to measure the pressure differences are installed:

between the gas spaces of the major vessels,i.e.

RPV to DW1 along MS1 RPV to DW2 along MS2 DW1 to WW1 DW2 to WW2

- along the length of key lines,i.e.

PCC inlet, vent and drain lines IC inlet and drain lines GDCS drain line WW1 and WW2 to RPV equalization line between upper and lower headers of the IC and PCC condenser units.

4.3.5 Water Level Water levels are determined at several location in the facility by differential pressure measurements with Rosemount model 3051CD and 1151DP pressure transducers. Transducers are installed to measure the actual water levels in the following vessels:

both drywell vessels both wetwell vessels the GDCS tank.

The equivalent " collapsed

• liquid levels are measured in locations which may have gas (steam or air) below the water surface. These are:

- in the RPV (total and 5 subsections) in each of the four compartments of the IC/PCC pool tank.

The liquid level in the following lines is also measured:

the LOCA vent lines the vent lines for the PCC condenser units.

4.3.6 Fluid Phase Indicator Nine conductivity probes are used to determine whether the fluid phase is liquid or gas at the probe location. The probes are located:

near the bottom (exit) of the LOCA vent lines from the DW to the WW

- at the inlet and outlet of the vent lines for each of the three PCC condensers.

- at the inlet of the lower box vent line for the IC unit.

4.3.7 Gas Concentration / Humidity Eight oxygen analyzers which have the capability to determine the oxygen partial pressure are mounted at three locations in each drywell and at one location in each wetwell. The oxygen

..=

1 ALPHA-606-0 / Page 71 analyzer can be used to determine the concentration (mass-fraction) of nonendensable gas at saturated and superheated conditions.

4.3.8 Power Wattmeters are used to measure the electrical power to the RPV heaters.

4.4 Instrument Calibration

^

i 4.4.1 Temperature Measurements inconel-sheathed Type K (Chromel-Alumel) thermocouples are used for nearly all temperature i

measurements in the PANDA test facility. Approximately one-third of these thermocouples are i

calibrated individually prior to installation in the facility using the thermocouple calibration procedure and hardware described in PSI report (4.5]. Platinum resistance temperature detectors (RTDs) are used for the reference calibration temperature. These platinum RTDs are calibrated in Bern at Eidgenossisches Amt for Messwesen (Swiss Federal Office of Metrology).

All the thermocouples used in PANDA are made from a few rolls or batches of bulk thermocouple cable purchased mainly from Philips (a commercial supplier). PSI checks each batch of thermocouple wire, upon receipt from the manufacturer, to confirm that the wire meets the manufacturers specification. This check is done by calibrating thermocouples made from each end of the batch or roll, over a temperature range of 50*C to 600*C.

4 In addition to the check of the thermocouple material when received from the manufacturer, as stated above, approximately one-third of the thermocouples used in PANDA are calibrated individually using the (4.5] procedure. The individual calibration is based on approximately 30 calibration points spread uniformly over the temperature range from 50*C to 200*C. The results of these individual thermocouple calibrations are combined for the thermocouples from each batch j

and statistically analyzed. The large sample individually calibrated from a batch provides confidence that the roll calibration is applicable to those thermocouples which have not been

]

individually calibrated. From the analysis a look-up table or a constant or first order (linear) correction to the standard calibration for this thermocouple material is determined for each batch.

The look-up table or correction to the standard for each batch is used to determine the temperatures for all thermocouples in each of the batches. The results of the analysis of the individual calibration data comgared with the roll calibration is used to show that the thermocouple accuracy requirement of 11.5 C for the temperature measurements is fulfilled.

No recalibration of the thermocouples is performed, because most of the thermocouples would be destroyed if removed from the facility. On the other hand the temperature ranges for the thermocouples are sufficiently low to not influence the thermocouple characteristics and the sheathed K Type thermocouples have a very good long term stability. It should also be noted that there is substantial redundancy in the temperature measurements, so it will be apparent if a thermocouple reading is significantly in error.

A sample of eight (approximately one-third) of the Pt100 resistance temperature detectors to be used to measure fluid temperatures at flow measurement locations is calibrated by a Swiss Calibration Service Laboratory (Calibration Laboratory accredited by the Swiss Confederation represented by the Eidgen6ssisches Amt for Messwesen at Bem). A sample calibration of these Pt100 sensors is sufficient due to the following reasons:

a) the combined most probable error for the sensor, the amplifier, and DAS of 0.4*C (4.6] is small compared to the required accuracy (1.5'C),

ALPHA 606-0 / Pago 72 b) the eight calibration results show that the standard error is less than that specified by the manufacturer, c) in the PANDA facility there is much redundancy for temperature measurements, therefore the noncalibrated Pt100 temperature measurements can be compared with other temperature measurements during homogenous temperature conditions to confirm the manufacturer's calibration of these temperature sensors.

The eight Pt100 temperature measuring devices are recalibrated after two years.

4.4.2 Flow Rate Measurements Each ultrasonic and vortex volumetric flow rate meter was individually calibrated in Bem at the Eidgenossisches Amt for Messwesen prior to installation in the PANDA test facility. A linear fit to the calibration data for each volumetric flow meter was determined and used for reduction of the flow meter data. A low flow measurement limit, which is due to the measurement principle and which occurs for a Reynolds Number of about 20000, is a specific attribute of all vortex flowmeters.

The hot-film flow meter used for measurement of mass flow rates for air added to the facility with the auxiliary air system is calibrated by the manufacturer, a German Calibration Service Laboratory (an accredited calibration laboratory).

The flow rate meters are recalibrated after two years, or earlier if there is an apparent error in a flow rate measurement.

)

4.4.3 Pressure and Possure Difference Measurements All pressure and pressure difference sensors used in PANDA are manufactured by Rosemount Inc. All these sensors are calibrated by PSI prior to installation in the facility according to the procedure defined in [4.7], except for the Model 2088 and SMART Rosemount pressure sensors.

For the Model 2088 and SMART sensors the calibration data obtained at the Rosemount factory are used.

The device used to generate and measure the reference pressure for the PSI calibration of all other pressure sensors is a Baratron System 170 manufactured by MKS Instruments, Inc. The reference is calibrated in Bem at Eidgen6ssisches Amt for Messwesen.

For the sensors calibrated by PSI approximately 10 calibration points are recorded for each sensor covering the range of pressures or differential pressures expected from [4.1]. A linear fit to the calibration points for each sensor are determined using the least squares method. The residual for the calibration points relative to the linear fit is determined for each sensor. The residual is used to establish whether or not each sensor meets its accuracy requirement.

i The pressure and pressure difference sensors are recalibrated after two years, j

4.4.4 Oxygen Partial Pressure Measurements The oxygen partial pressure is measured at some locations in the PANDA facility in order to infer the air partial pressure and humidity. The voltage output of the sensor used to measure the oxygen partial pressure is a function of the sensor temperature and the differential oxygen pressure across the element. (4.8) describes an evaluation of the feasibility of using this sensor to determine the air partial pressure and humidity in the PANDA tests. Based on the evaluation in (4.8], it is not necessary to calibrate this instrument. Nevertheless a procedure for demonstrating

ALPHA-606-0 / Pago 73 the sensor performance was developped [4.9] and carried out for all eight oxygen sensors used in PANDA.

4.4.5 Conductivity Probe Conductivity probes are used to establish whether the fluid phase at the probe location is liquid or gas. Prior to the transient test series for which the conductivity probe measurements are required, the water level near the probe is varied so that the probe is exposed to only gas and then to only water. The output of the probe is monitored and recorded at the Data Acquisition System (DAS) while the fluid phase the probe is exposed to is changed. This will be done to confirm that the probe can detect whether it is exposed to gas or water.

4.4.6 Power Measurement As described in section 3.E.1 the 115 electrical heater rods of the RPV, with a maximum capacity of 1.5 MW, are divided in 6 groups. Four groups with 23 heater rods in each group are on/off controlled and two groups with 4 and 19 heater rods, respectively, have a continuous power control. Four Sineax PO502 Wattmeters are used for measuring the heater power of the four on/off groups. The power of the two controlled groups is measured by Sineax 6P1 Wattmeters. All six Wattmeters are calibrated by an accredited Swiss Calibration Service Laboratory. In addition, the total power of the RPV heaters is generated using an electrical summing of the six measured group powers. The six wattmeters are recalibrated after two years.

ALPHA-606-0 / Page 76 5.2 General Description of Data Acquisition System The data acquisition system is an integrated system which measures signals and converts them to engineering units. It consists of components completely integrated in order to enable the user to perform all the significant actions related to data acquisition and the data conversion process.

The front end of the DAS comprises an of a HP 3852 main frame plus four HP 3853 extenders.

The main frame and each extender contain a HP 4470416-bit high-speed voltmeter and several HP 44713 24-channel multiplexers in which 24 PSI produced preamplifier / active filter units are integrated. The number of multiplexers depends on the extender. The sensor cables are connected to the terminal module of a multiplexer and the signals are then amplified and filtered in the PSI produced unit. The gain of the preamplifiers is about 40 and the active filter is a second order low pass Butterworth function filter set to 18 Hz. This setting is low enough to eliminate 50 Hz signals which might be introduced through power supplies, and high enough not to filter out any data from the 0.5 Hz scan rate of the DAS. The amplified and filtered signal then is fed into one of the multiplexers. There is a total of 30 multiplexers (e.g. 720 measurement channels) spread over the five different levels. The multiplexed analog signals are read by the high speed g voltmeters which are located on each level. The voltmeters have a 320 mV range and the output 4 is digital data, i.e. the data transfer between the extenders and main frame is already digital.

4 The main frame and the fnur extenders are located on five different levels of the PANDA facility (cf. Fig. 5.1). The main frame is located at a height of 2 meters. The extenders are located at heights of 6 m,10 m,14 m, and 18m. This reduces the amount of cabling required and minimizes electrical noise due to long cables. In order to eliminate or reduce temperature influences the five racks for the main frame and the four extenders are each temperature controlled.

The back end of the DAS is made up of HP 1000A990 Real Time computer system. This system, 4

which can be operated interactively, runs with software developed by PSI. This software is described in the following section.

5.3 Data Acquisition System Software 5.3.1 General Description The DAS Software is performing the following main tasks:

I During start-up (1) Initialization and start-up of all necessary multiple tasks of the DAS software package through the main DAS task.

(2) Reading the actual channel list which is the basis for the definition of all channels which have to be measured. Tre channel list contains also the information about the type of connected sensor pec channel and the kind of conversion and the corresponding conversion coefficerts per channel which are also used by the DAS software.

(3) initialization, programming and start-up of the HP3852/HP3853 front end Data Acquisition System.

\\

ALPHA-606-0 / Pagn 77 l-i l

11 During normal operation (In this phase a so called monitor loop is the operator interface. Using specific defined keys the different possible subtasks can be initiated. In addition some other tasks are continuously running).

a) Continuously running tasks:

(4)

Service request task i

The front end data acquisition system is running in a continuous scan mode after 2

start-up. Every time a scan over all channels is completed an interrupt signal is sent to the real time computer system. The interrupt signal activates the service request task which is then reading the provided measurements. Depending on the actual requests the data are discarded or transferred to the conversion task.

(5)

Conversion task The conversion task is waiting for data from the service request task. If data are available the conversion, due to the actual requirements, for all measured channels is carried out and the data is then sent to other tasks again depending on the actual requirements. The standard data conversion is described in detail in Section 5.3.2.

j (6)

Communication task The communication task is waiting for data from the conversion task. If data are available the conversion task sends the data to the Trending / Data Storage system over the ETHERNET connection. The available data, corresponding to the actual requirements, are marked according to the requested use: for trending and process visualization or/and for data storage.

(7)

Hard copy task From all DAS software package tasks all information which has to be printed is sent to the hard copy task. The hard copy task formats the information and sends it to the actual chosen printer. The printed information (called DAS protocol) covers a set of information which makes a run of the DAS software fully traceable (Date/ times, task versions, operator requests, conversion status / errors etc.).

(8)

Watching over task This task is controlling all other tasks of the DAS software package, in addition the task lo also controlling the central processor unit utilization of the HP1000A990 system and reports high utilization on the DAS protocol.

(9)

Monitor task The monitor task is the interactive interface for the DAS operator. All requests for controlling the DAS have to be entered through this task. The description of the available subtasks is given just below.

b) Subtasks through monitor task (initiated by pressing function keys):

l (10) Initializing / shutting down the ETHERNET connection to the Trending and Data Storage System (cf. Section 5.1. (2)).

(11) Start / stop data transfer to the Trending and Data Storage System.

(12)' Selection of printer on which the DAS protocolis printed.

(13) Definition of measurement cycles. Three measurement cycles have to be defined a) burst cycle, b) data storage cycle, c) trending and process visualization cycle.

(14) Enable / disable data storage task: for the local data storage a file name and an experiment number have to be defined for enabling data storage. By disabling the data storage the actually defined file is closed.

ALPHA-606-0 / Page 78 (15) Stop / Start data Storage: according to the actual cycle the measurements are stored by the DAS (as a back-up) and marked so that the Treading and Data Storage System can recognize the data storage mode and produce a special data storage file (cf. Section 7).

(16) Burst measurement configuration: by defining a burst measurement storage file name

i and choosing an automatic or manual burst mode, burst measurements are enabled according to the actual chosen burst measurement cycle. For automatic burst mode a special measurement channel is controlling the start and stop of a burst measurement. For manual burst see next task description.

(17) Stop / Start manual burst measurements: Initiation or stop of manual mode burst measurement.

(18) Measurement data hard copy printout; all or selected channels in microvolts or j

physical units.

(19) Thermocouple reference temperatures printout.

(20) DAS calibration mode: special task for the calibration of the DAS front end (Mulitplexer Terminal, Preamplifier, Mulitplexer, Analog / Digital Converter).

(

(21) Single channel reading mode with hard copy protocol.

(22) Channel overwrite mode: the measured value of a specific channel is temporarily overwritten by a manually entered value.

Starting and running the DAS software produces always a so called 'DAS protocol *, which contains all relevant information about the used task versions, about the chosen subtasks and I

about any problems which occurred in any of the DAS tasks. Based on the DAS protocol a run of the DAS software is fully traceable.

Due to the specific nature of the different available subtasks, many interlocks are needed or desirable. Instead of a complete listing of the about 35 interlocks, only a typical example is given here: during data recording mode (e.g. When data of a real experiment are collected for later use) the channel overwrite mode (22) cannot be activated.

In the following the ' normal' operation of the DAS software package during the data recording period of a real experiment is shortly described. The front end part of the DAS (cf. Section 5.2)is i

taking measurements according to the standard burst measurement rate of 5 Hz. The back end l

part of the DAS is reading through the service request task (4) all the measurement carried out by the front end part. Depending on the actual data request (standard data storage and data visualization rates are 0.5 Hz) the service request task transfers the data to the conversion task (5). The conversion task is carrying out the whole conversion chain which is described in detail in the next section. The converted data is then stored on the DAS disk (as a backup) and transfered to the communication task (6). The communication task finally sends the data to the trending and data storage system (cf. Section 5.1 (2)), where the main data storage takes place continuously.

Any specialty or problem occurring during this ' normal' operation are also printed on the DAS protocol, e.g. especially messages from the conversion task (5) due to, for example, instrument overflow.

5.3.2 Data Reduction and Processing The whole on-line data reduction and processing procedure is based on a channel list (cf. Section 5.3.1 (2)) and the conversion task (cf. Section 5.3.1 (5)). The channel list and a generic part of the conversion task are used for the basic conversion to engineering units (Section 5.3.2.1) and a PANDA specific part of the conversion task is used for the calculation of derived quantities (Section 5.3.2.2).

(i.e. Section 8.3 and 10 of the PTF) and the softwaro utilized is documented in Section 6.2.2 of the PTF.

4 5.3.2.1 Basic Conversion to Engineering Units j

For the basic conversion to engineering units the channel list, which is read during the DAS atart-a up (cf. Section 5.3.1 (2)) is the main source of information, in Table 5.1 an excerpt from a channel j

list is presented. Below the table header written in bold, each row defines a measurement channel for the DAS software. Fifteen specific examples (out of the total of 720 channels) are chosen which are used for the following description of the bas!c conversion. First the meaning of j

measurement the thermocouple offset correction is periodically calculated and stored in the offset correction T_Ref/A for the corresponding thermocouple channels (the reference temperature is measured in each multiplexer terminal and the corresponding thermocouple channels are all the channels which are connected to this specific terminal modul and which have the ID code 1). In j

l the DAS channel list (cf. Table 5.1) the thermocouple offset voltages are all zero because the actual values are, as just described, calculated by the conversion task (the first time during start-l up).

i The ID code range from 201 to 500 defines different kind of sensors but all having a linear conversion characteristic. The ID code subranges are only used to group the different kinds of sensors. The conversion from true measured voltage U, to engineering units Y, has the form Y, = T_Ref/A + U,

• Koeff._B (5.1) 4-and is directly related to the calibration or calibration curve fit of a sensor.

The ID code range from 501 to 600 defines sensors with a bivalent characteristic, e.g. the sensor j

signal can only take two different values. For the conversion to engineering units only the value of 1

T_Ref/A is used:

= 0, if U, < T_Ref /A (5.2)

Y"

= 1, if U,2 T_Ref/A For sensors with a trivalent characteristic the ID code range from 601 to 700 is used. This kind of sensors can only take three different values. The conversion from true measured voltage in engineering units is carried out according to the following:

= 100,if U, > T_ReflA + Koeff._B (5.3) y,

= 0, if T_Ref/A - Koeff._B < U, s T_Ref/A + Koeff._B

= 50, if U, s T_ReflA - Koeff._B The last step in the basic conversion to engineering units is called special conversion / individual correction. This step allows another channel specific linear conversion, based on the actual value, to be carried out. For the PANDA axperiments the individual corrections have been applied for three different sensor types: thermocouples, pressure and pressure difference transmitters, oxygen sensors. The general form of the special conversion / individual correction is as follows:

Y,,, = Spez_Konv_C + Y

• Spez_Konv_D (5.4) where Y is the measured value in engineering units after the ID specific conversion and Y,,,is the measured value after the special conversion / individual correction.

According to Section 4.4.1 for each roll or batch of bulk tnermocouple cable a calibration was done, so that the deviation from the standard conversion based on [5.1] is known. For each thermocouple this deviation is corrected through an individual correction according to the roll or batch from which the thermocouple was fabricated.

)

For all pressure and pressure difference (including level pressure difference) measurements the

)

engineering unit value after the ID code specific conversion represents the value effectively measured by the transmitter. Due to the water filled pressure transmitter pipes (from the transmitter to the pressure taps) this pressure or pressure difference is different from the real process pressure or process pressure difference which has to be measured. To account for these water filled legs an individual offset correction (Spez_Konv_C in equation (5.4)) is used. This correction is based on (4.3] (cf. also PTF Section 5.5).

@r the oxygen sensors the individual correction is used to account for the individual sensor offsets, which have been determined during oxygen sensor performance verification test (cf. PTF Section 5.2). That means, only the coefficient Spez_Konv_C is used in equation (5.4).

5.3.2.2 Derived Quantities Up to now all conversion steps to engineering units have been related to only one measurement / sensor, in this section the so called derived quantities are describe? ! e. further conversion of a quantity based on more than one measurement / sensor. In essence L ere are three types of derived quantities, namely level measurements (conversion from pressure difference to level), flow measurements (conversion from volume to mass flow) and air partial pressure measurements (conversion from oxygen sensor voltage to air partial pressure). The derived quantities conversion formulas are described 'n [5.2] and are programmed in the PANDA specific part of the conversion task (cf. Section 5.3.1 and 5.3.2). In addition the other measurements / sensors which are used for the calculation of a derived quantity are also defined in this PANDA specific part of the conversion task and shortly described in the following paragraphs.

For a detailed description and the actually used conversion task version refer to the corresponding test operating records (PTF Sections 8.3 and 10) and DAS software j

documentation (PTF Section 6.2.2).

For the calculation of levels, the pressure taps vertical distance, the liquid density and the gas density above the liquid level have to be known, in addition to the pressure difference measurement. Therefore the tap distance and the temperature measurements, from which the liquid density has to be calculated, need to be defined for each level calculation. For the gas density three options are used: pure steam, steam / air mixture, and pure air. Correspondingly gas temperature measurements and eventually pressure measurements have to be defined for each i

level calculation.

]

For the conversion of volume flows to mass flows, again, the densities have to be known. For gas flows, again, three options are used: pure steam, steam air mixture, and pure air. Therefore, for each mass flow calculation (i.e. gas or liquid flow) either the temperature measurement or the temperature and pressure measurement at the flow measurement location has/have to be defined Finally, for the third type of derived quantities, for each oxygen sensor the appertaining sensor temperature measurement has to be defined. Because the reference air pressure for all oxygen sensors is the environment pressure, the barometric pressure measurement can be used for all air partial pressure calculations.

According to the above description it is obvious that the calculation of a derived quantity is fully traceable, i.e. from the derived quantity the primary measurement can always be recalled.

Therefore the primary measurement is overwritten by the derived quantity 'i.e. prewre difference by level, volume by mass flow, oxygen sensor voltage by air partial pressure) and no new data records have to be created.

6. Facility Characterization Tests Before PANDA could be employed in experiments intended to simulate the behavior of the GE SBWR containment, a number of system characterization tests had to be performed. These included vessel leakage and heat loss tests, and system line pressure drop measurements. The heat losses from i

various system components are needed for calculation of energy balances, which in tum are used to assess system performance. System line pressure drop characteristics had to be measured to ensure that the PANDA facility adequately simulates the pressure loss characteristics of the full scale SBWR system. Accurate measurement of heat losses and pressure drops are necessary to reliably model the system with computer codes.

6.1 Vessel Cold Leak Test The leak rate for each vessel was determined by calculating the inventory loss of the pressurized system over a period of time. The change in inventory is found with pressure and temperature measurements in each vessel. Using the perfect gas law and setting the volume-averaged {

temperature within the vessel equal to T, the gas inventory in moles is simply:

I= PV (6.1)

RT The average molar leak rate is calculated from the initial and final inventories:

A='

2 (6.2)

T where t is the elapsed time between the measured inventories I, and I,.

The leak test was conducted by pressurizing the system to roughly 5 bar with air and then closing valves to isolate the vessels. Leakage from the PCCs was included with the drywells by leaving feed line connections open. The two wetwells were treated as a single vessel since the large connecting lines proclude isolation from one another. The two drywells were treated similarly for the same reason. Measurements of vessel temperatures and pressures wer9 recorded over a period of about five days. The measured leak rates, listed in Table 6.t were found to be extremely small, except for the RPV.

)

l Though the fractional leak rate for the RPV is large compared to the other vessels, the RPV comprises only 5% of the system volume and so the total molar leak rate from this vessel is small.

Details of the test procedure and data reduction can be found in [2.1] and [6.1], respectively.

6.2 Vessel Heat Loss Test Heat loss tests were conducted by heating the vessels with steam and then allowing them to cool after each had been isolated. An energy balance on each vessel during this cool-down phase can be written as:

Q = de j pudV + C.dT dr (6.3) de y

where Q represents the total vessel heat loss rate and C,,, denotes the heat capacity of the vessel structure. The term u refers to the intemal energy of the fluid (steam and water) within a vessel of volume V. The time rate of change of fluid intemal energy must be determined indirectly, through temperature measurements, and so it is desirable to write the heat losses in terms of a single heat capacity and temperature:

i 0 = C dT (6.4) l de This approach assumes that a single temperature can be used to represent the temperature of the l

entire vessel as well as the steam and water inventories. This is a reasonable assumption because the vessels are well insula ed, minimizing gradients along and across the vessel walls. Also, the vessels l

were steam-filled at tha beginning of the test and so the entire gas space and inner wall surface followed the steam saturation temperature as the vessel cooled. Further details on heat loss calculations can be found in [6.2].

The heat loss test was conducted by heating all vessels with steam and establishing a pure l

steam atmosphere at roughly 4 bars and 140*C. Valves were closed to isolate the RPV, GDCS, wetwells, and drywells. As with the leakage test, the wetwells and drywells were each treated as single vessels since they cannot be isolated from one another. Condenser heat losses were not included in this test and so the feed and vent line valves were closed to isolate the condensers from the remaining vessels. After isolation the resulting cool-down transient was recorded over a period of about 60 hours6.944444e-4 days <br />0.0167 hours <br />9.920635e-5 weeks <br />2.283e-5 months <br />. Test procedure is detailed in [2.2].

Vessel heat losses as a function of temperature are plotted in Figure 6.1. Total heat losses for an isothermal system are also pbtted. In Figure 6.2 the system heat losses as a fraction of core i

power has been plotted. Typical vessel temperatures for the transient tests were selected for estimation of total system heat losses. The detailed results from the heat loss tests are summarized in (6.2].

ALPHA-606-0 / Page 88 6.3 System Line Pressure Loss Tests The pressure loss characteristics of each PANDA ' system line" (the piping intended to simulate the lines connecting the SBWR drywell, wetwell, GDCS tank, PCC condensers, and RPV) must be measured to ensure that the lines adequately model their full scale counterparts. The pressure drop along a particular line can be expressed as:

A,,

g where de is the water or gas mass flow rate, p the density, and A and K are the line cross sectional area and overallloss coefficient for each line segment. Details of the scaling criteria and system line j

construction are contained in (3.1].

in each test the differential pressure, mass flow, and fluid temperature near the flow meter were measured. For gas flow the absolute pressure was also rneasured so that the density could be calculated. A least squares method was used to calculate polynomial fits to the data, which were used (

to calculate loss coefficients as a function of mass flow rate.

The PCC feed and vent lines were tested using air at room temperature while the GDCS drain and equalization lines were tested with water. Measurements indicated that A/8 for these lines are within 10% of the design value. The loss coefficients of the feed lines were well matched, as were the loss coefficients of the vent lines.

The main steam lines were tested using steam at three different flow rates. The loss coefficients for the two lines were closely matched and roughly 10-15% higher than the design value. The PCC1 vent line was tested with steam at two flow rates. The loss coefficient compares well with the measurements made with air. The PCC1 and PCC2 feed lines were tested with steam at three flow rates and A/8 for the two lines were in good agreement, though the loss coefficients for the steam testr. are about 7% lower than for the air tests.

The results from the system line loss measurements are summarized in (6.3].

7. PANDA Experimental Data Base 7.1. Introduction During the data recording phase of a PANDA test the measured data are stored on a disk-file by the Trending Workstation (cf. Section 5.1, item (2)). This disk-file, called a flat file, contains the raw data in an ASCll-coded format. After completion of a test, the corresponding flat file is transferred to the LTH SUN cluster over an ETHERNET connection by means of FTP tools.

In a second phase, the data contained in the flat fi'e, are loaded in an ORACLE data base called PANDA Experimental Data Base. All data recordsl and information contained in the record j

header are stored in a set of Raw Tables. Test data are through this process rearranged from the time snap shots to time dependent records per measurement channel. Then a second set of

]

tables (PANDA Test Tables) is created in order to provide convenient access to the test data and a more complete set of information (see section 7.2).

Access to test data is then available by means of diverse ORACLE tools, which allow different data representations or data manipulations like graphical visualization, standard analysis or queries; based on simple structured query language (SQL) statements, all these tools offer a complete package to handle the very large amount of data which represent the PANDA data.

l Extemal data transfer is also possible by means of ORACLE tools. It can be accomplished in two ways: formatted ASCll-coded files and/or ORACLE export files of PANDA Test Tables. Data base export files are generated by ORACLE and can be directly imported by any compatible ORACLE version (see section 7.4).

7.2. Structure of PANDA Experimental Data Base The PANDA Experimental Data Base is structured considering two sets of tables: a) the PANDA Raw Tables and b) the PANDA Test Tables. Set (a) contains test data assigned to DAS channels and set (b) provides more convenient access to the data by assigning them to corresponding PROCESSID.

Using the ORACLE loading tool SQLLOAD, the PANDA experimental data contained in the flat file, are stored in the Raw Tables. Due to the limited size of ORACLE tables (max. 254 columns),

the data cannot be stored in one table; the 720 channel are loaded into 5 tables named PANDA _testnb_EXTENDERn (n=0,1,2,3,4) corresponding to the channel assignment to the DAS extenders while record headers are stored in the table PANDA _testnb_ HEADER.

Since data records are stored in several tables, all record segments must be identified uniquely.

2 Therefore an ORACLE SEQUENCE (REC _.lD) is defined during the loading process in order to l

1 A record is a measurement scan over all DAs channels: at a given tirne.

2 A sEcuENCE is an ORACLE object used by sOLLoAD which attaches an unique nurrber to all sequencially read rows.

i l

I

ALPHA-606-0 / Page 90 attach identifier to each record segment in all tables; this variable REC _ID will be used to link record segments to each other, especially to link measurement to the corresponding time record.

In a second phase, a se d tables called PANDA Test Tables is created in order to provide a more convenient way to access tne test data. These tables group measurements together in different categories and assigned data to their corresponding PROCESSID. In order to assure i

consistency in the assignment of CHANNEL to PROCESSID, all SQLPLUS scripts used to create the PANDA Test Tables, are generated by a FORTRAN program (create _ panda _ scripts./) which reads the DAS channel assignment defined in the Test specific KBT file (ex: kbt99999999.o12 for M3A, cf. Section 5.3.2).

7.2.1. PANDA Raw Tables For each test a set of six tables is created in order to store all information contained in the test flat file. Due to the table sizo limitation, which allows a maximum of 254 columns, data are distributed in five different tables in accordance with the channel assignment on the DAS extenders and the k l

record header information is stored in un additional sixth table, called PANDA _testnb_ HEADER.

7.2.1.1. List of PANDA Raw Tables:

1)

PANDA _testnb_ HEADER header information: time and explD - raw data 2)

PANDA _testnb_ EXTENDER 0 data from extender 0 channels 1" to 96*

3)

PANDA _testnb_ EXTENDER 1 data from extender 1 channels 97* to 216*

4)

PANDA _testnb_EXTENDEA,.

data from extender 2 channels 217* tc 336*

5)

PANDA _testnb_ EXTENDER 3 data from extender 3 channels 337* to 528*

j 6)

PANDA _testnb_ EXTENDER 4 data from extender 4 channels 529* to 720*

3 Data are loaded in these tables by a SQLLOAD script, which sequencially reads the ASCll-formatted flat file. While the n* channel data is assigned to the corresponding column, named

'CANALn", the header information is stored in the table PANDA _testab_ HEADER as described below. During the loading process an ORACLE SEQUENCE defines a record idemifier (REC _ID) attached to each record segment.

All PANDA Raw Tables have the structure; one column for the record identifier (REC _ID) and a corresponding number of columns for the test data.

l 7.2.1.2. Table: PANDA _festnb_ HEADER The table PANDA _testnb_ HEADER contains all information included in the record header and l

additional information like record identifier (REC _ID), time binary code (l#), day time in milliseconds (TIME _MS) or time offset (TIME _first_ REC) corresponding to day time of the first record. While REC _ID is defined during the loading process, the conversion in binary code or in s

All tables PANDA _testnb_EXTENDERn are structured the same; they all contain data from groups of channels and the additional record identifier REC _ID, which is automatically created during the loading process by an ORACLE SEQUENCE.

actual parameters used for data analysis or indication of possible DBM (Data Base ModificaSon).

These PANDA Test Tables providing a more convenient data representation will actually replace the above described set of Raw Tables. After use for the creation of all Test Tables, corresponding Raw Tables are backed up with the ORACLE export tool and then droppe.d from the PANDA Experimenta! Dats Base. When created PANDA Test Tables are also backed up and kept in the data base; they are now used as data source for PANDA test data analysis.

With these Test Tables, data are structured differently; they are no longer related to the channel number, but directly to their corresponding PROCESSID; columns are labelled with PROCESSIDs.

In order to assure conformity in the PROCESSID assignment, the whole set of Test Tables is created by means of SQL scripts which are automatically generated by the FORTRAN program create _ panda _ scripts.f6 l

l The set of PANDA Test Tables is briefly described below.

7.2.2.1 List of PANDA Test Tables Since temperature measurements are the most numerous, the Test Tables partition assigns the PANDA instrumentation several temperature categories and one class for all non-temperature measurements, while reserve channels are stored in a separate table. Two additional tables complete the set of Test Tables; one for general information (INFO _ TESTS) and the other to contain selected data from the Test specific KBT file (PANDA _testnb_KBT).

ALPHA-606-0 / P gs 97 ff a specific inadequacy in the PDB is identified and a Data Base Modification (DBM)is necessary this is done accordingly to an approved procedure (7.1).

The DBM process includes an assessment of a specific PANDA data base inadequacy and its resolution, the execution of the modification, the verification and final approvals. All DBMS are logged and documented in the PANDA Test File (PTF, Sections 8,9 and 10).

7.4 External Data Transfer The purpose of extemal data transfer is to create output file, which can be used by any other compatible system; it can be accomplished in two different ways: generating ASCll file or ORACLE export file. A description of both possibilities is given in the following.

7.4.1 ASCll File Output ASCl! files can be created with ORACLE SQLPLUS; by means of the SPOOL command, query results can be recorded in a specified ASCll output file (output.lst). SQLPLUS options can be used to set up page, line or number format, to define title or column name, to number pages or to set up the execution date. More information about setup commands can be found in the ORACLE SQLPLUS manuals.

These ASCil files for data transfer consists of two parts; the first one giving the SQL SELECT statement used to list and store all data records and a second part containing the table of actual data. The SQL statement gives the list of all variables contained in the table; variables and corresponding columns are identified by PROCESSIDs. An example of ASCll file for data transfer is given below.

7.4.2 ORACLE Export File The purpose of creating ORACLE export files (export.dmp) is to transfer selected set of data with (

a complete Data Base structure. The Export utility is used to write data from an ORACLE database into operating system files (on disk or tape) in ORACLE-binary format. These files can i

be stored independently of the database, or read into another ORACLE database using the I

import utility. Because of their special format, export files can only be read by the import utility; they are complementary programs, that constitute a single utility.

Used to move data between ORACLE data bases, Export and import utilities are also used to back up, archive and retrieve data.

For using export tools between data bases ORACLE versions must be compatible; in the case of the PANDA Experimental Data Base, the ORACLE version is ORACLE 7 Server Release 7.1.

An example of Export file creation is given in the following.

Exoort File Creation:

This example shows how all Raw Tables for the Shake Down test SDM01 have been exported; parameters given in export _SDM01. par file are needed to define the list of tables, which must be exported, the name of the export file and the log file.

During the import the corresponding tables are either created or, after confirmation, overwritten if they already exist in the actual ORACLE database.

After the importing have been completed, tables are recovered and the PANDA Experimental Data Base provides exactly the same structure as before the table export. Data might be imported into any other compatible systems (compatible with the ORACLE version ORACLE 7 Server i

Release 7.1).

8. Error Analysis q

A variety of measurement instrumentation was used to monitor preparation and performance of i

experiments with the PANDA test facility. An evaluation of measurement accuracy is a necessary aid

)

in venfying instrument performance and interpreting experimental results. An error analysis for PANDA j

instrumentation characterized uncertainty in the following parameters:

• temperatures from K-type thermocouples

• temperatures from RTD's (resistance temperature detectors)

• absolute and differential pressures

• waterlevels

• steam / air and liquid (water) mass flow rates

• noncondensable gas (air) partial pressures

)

• reactor pressure vessel core output power Some of the parameters listed above are the product of several measured quantities. Inaccuracy in these measurements must be combined to estimate total inaccuracy in the measured param estimate is obtained with an ' error propagation

• formula. The standard error in a quantity u comprised of N measured values x, will be defined as:

ue a

\\

[ dx 2

2 0,

(8.1) 0 =

n.: <

u where o,is the error in the measured value. The o, are obtained from manufacturer specircations and i

instrument calibrations. Adding errors in such a fashion implicitly assumes that the errors are normally i

distributed, independent, and random in nature. The upper bound (or worst case) error takes a similar form:

B h,,l (8.2) c m.

=

g This can be thought of as the total error when all errors are systematic errors biasing the measurement in the same manner.

A detailed formulation of error for each instrument is contained in (4.6]. Table 8.1 is included here to provide representative standard and upper bound measurement errors.
