The IC system and the PCC system perform vital roles in removing heat from the reactor vessel and the containment during certain postulated operating and accident conditions. Full-scale, prototypical condensers for these systems are to be tested at full pressure, temperature and flow conditions. The test facilities speciDed for this program are not representative of the SBWR systems of which these condensers will be a part. The specified tests are component " Design Quali6 cation Tests" tests and therefore the test system performance is not intended nor expected to be representative of the SBWR system performance.
3.2 Test Objectives- Passive Containment Condenser. The general objectives of the full-scale PCC test are as stated in the following paragraphs. The speci6c objectives described in Paragraph 5.1.1 provide additional details to the general objectives. 3.2.1 Thermal-Hvdraulic.

A full-scale unit (two modules) of the Ansaldo designed PCC as described by the documents referenced in 2.2.b and 2.2.g will be tested to accomplish the objectives stated in ! Section 3.1. Most of the testing will be done at near-steady-state conditions covering the range of ! the process variables required for SBWR. The condenser pool temperature for most tests will be [ the equilibrium (steady-state) value and the water level in the pool will be maintained at the l normal level (full). The inlet (drywell) pressure, the steam flow rate and the Dow rate of l noncondensible gases in the inlet steam will be systematically. varied. The tests will include .! suf6cient pressure / temperature cycles (five times the number of cycles used for design) to ( con 6rm the structural integrity. ' 3.4.3 IC Tests. One-half (single module) of a full-scale unit of the Ansaldo designed IC as described by the documents referenced in 2.2.a and 2.2.e will be tested to accomplish the [ objectives stated in Section 3.2. The tests will be both steady-state performance' tests and slow t L transients simulating the thermal cycles de6ned in the IC design specification. At the conclusion j of the testing the condenser will be inspected, using the normal ISI procedures, to con 6rm that [ there is no excessive deformation, crack initiation or excessive crack growth rate. l t I c I

- 4. TEST FACILTIY REQUIREMENTS 4.1 Facility Renuirements for the PCC 4.1.1 Principal Functions and Comoonents. The test facility must have a tank simulating the PCC pool in SBWR. A full-size PCC unit will be provided by the Test Requestor to be mounted inside this tank. The facility must be able to supply steam, water and noncondensible gases in quantities and at conditions which are representative of those anticipated for the SBWR PCC. Thermal hydraulic and structural instrumentation will be installed for measuring the parameters of interest. The rate of heat transfer from the inlet gas (steam and noncondensibles) to the PCC pool will be determined.The heat losses from the inlet gas supply lines to the surroundings shall be minimized and shall not exceed 1 MWth.
e C GENuclear Eriergy 23A6999 SH NO. 9 REV.4 Figure 4-1 gives an approximate schematic of the PCC test facility.The principal components of this facility shall be: A supply of saturated st :am. A supply of noncondensible gases (air or nitrogen and helium). Condensate drain tank. Noncondensible vent tank. PCC pool tank. Piping and valves. 4.1.2 Test Variables. The independent test var.iables shall be: PCC intet pressure. Inlet steam Dow rate. Inlet noncondensible flow rate. The following variables need to be controlled: Temperature of the inlet steam or steam / gas mixture. PCC pool level (supply makeup to maintain constant level). PCC pool temperature (maintain constant). Condensate tank pressure (maintain equal to PCC inlet pressure). Condensate tank level (control tank drain How). Vent tank level (control tank drain Dow). Dependent variables: Vent tank pressure or PCC differential pressure. Condensate Dow rate (heat transfer rate). 4.1.3 Comnonent Renuirements.
'4.1.3.1 Steam and Nonenndensible Gas Sunnlies. Saturated steam with quality greater than 99.8% shall be supplied to the PCC at a controllable Dow rate for PCC inlet pressure in the range 69 to 689 kPa gage (10 to 100 psig). Available continuous steam Dow rate shall be at least 6.5 kg/s (14.3 lb/s) at 6S9 kPa (100 psig). It is desirable to have available a continuous steam Dow rate of 9.75 kg/s (21.5 lb/s) at 689 kPa gage (100 psig) (based on 20 MWth). ;
I Noncondensible gases (air or nitrogen and helium) shall be supplied to the PCC at a controllable How rate for PCC inlet pressure in the range of 69 to 6S9 kPa gage (10 to 100 psig). Steam / gas mixtures in the range of 0 to 50 noncondensible mass percent are required. Noncondensible mass percent is dcEned as 100 multiplied by the ratio of the noncondensible mass to the total mass.

p w M' iif/ GENucteerEnergy 23A6999 SH NO.10 REV.4 The noncondensible gas supplies shall be sized such that the following flow rates can be prosided to the PCC: Air (or nitrogen) 2700 Nm3/h at 69 to 689 kPa gage (1678 SCFM at 10 to'100 psig) Helium - Sufficient to fill the PCC with helium at 689 kPa gage (100 psig) in 15 minutes. The flow rates of steam and noncondensible gas shall be controlled using critical flow devices so the flow rates are independent of the PCC inlet pressure. The flow rates can be controlled either by variation of the stagnation pressure or the critical flow area or a combination. Provision shall be made to control the temperature of the steam or steam / gas mixture at the PCC inlet. For steam tests, the inlet steam shall be saturated,'or with a specified superheat For tests with a steam / gas mixture, the temperature shall be controllable between saturated and 44*C (80'F) superheated. 4.1.3.2 PCC Pool Tank. The PCC pool tank shall be a rectangular elevated tank, open to the atmosphere for the purpose of containing the PCC and the water which cools it. The tank shall be covered, and shall have an opening of 2 m 2 (21.5 ft2 ) in the wall,250 mm (9.8 in) above the pool normal water level, for boil-off. The tank shall be large enough and have provisions for internally attaching, with prototypical mounting hardware, a complete full-scale two-module PCC unit, and prototypical inlet, vent and condensate drain piping. The pool depth shall be sufficient to submerge the PCC to a prototypical water level.The required dimensions of the pool are shown - in Figure 4-2. Systems shall be provided to fill the pool with highly purified water prior to a test, to' control the tank level and replace boil-off during a test, and to drain the pool for maintenance or modifications to the PCC. The makeup water system'shall be sufficient to maintain a constant pool level at the maximum condensation rate for a period of at least 4 hours. Pool boiloff (no moisture carryover) with 15 MWth heat transfer was calculated to be approximately 6.9x10-3 m3/s (110 gpm). The makeup water shall be the same quality as the pool water. It shall be - distributed in the pool such that nonprototypical flow patterns and temperature distributions are avoided. The water quality requirements for the PCC pool tank are shown in Table 4-5. 4.1.3.3 Condensate Drain Tank. A tank shall be provided for collecting the water condensed and: drained from the PCC. The condensate drain tank shall be a closed tank, normally pressurized above atmospheric and partially filled with water. The elevation between the PCC pool tank bottom and the condensate drain tank water level shall be adjustable between 2.0m (6.6ft) and 3.5m (11.5ft). The condensate from the PCC shall discharge to the drain tank beneath the water level. A line shall be provided to drain water from the tank during a test to maintain the water level at a controlled position. The tank and drain shall be sized such that flooding of the tank is prevented and good control of water level can be maintained during testing with the greatest
x d ' .- GENuclear Errergy 23A6999 SH NO. ll i REV.4 l expected condensate flow rate. The condensate flow rate for 15 MWth heat transfer at 6S9 kPa gage (100 psig) steam inlet pressure was calculated to be 8.2x10-3 m3/s (130 gpm). ! The condensate drain tank shall be i, .ded with systems to fill the tank to a predetermined level, and to control that level during a test at a constant value by adjusting the rate of tank' drain. The tank gas-space during testing shall be maintaired at the same pressure as the PCC inlet flow. The method of equalizing pressure with the PCC inlet shall not divert flow from the PCC inlet - line. Figure 4-1 shows one method of controlling condensate tank pressure by injecting high pressure air into the tank and using a pressure control valve on the gas outlet line. Venting of the gas space in the tank may be necessary for pressure control or if noncondensible gas is carried into the PCC drain. - 4.1.3.4 Nnncondensihte Vent Tank. Noncondensible gases, separated in the PCC shall be vented - [ to a closed tank. The elevation of the highest expected water level in the vent tank should bc lower than the lowest expected water level in the condensate drain tank. At some conditions the flow into the vent tank may include uncondensed steam, noncondensible gases and liquid ! condensate carried over from the PCC lower plenum.The vent line from the PCC shall terminate , in the vent tank.The vent line discharge in the tank shall be arranged such that testing may be i performed with discharge either submerged, as in SBWR or unsubmerged. Provision shall be i made to drain water from the bottom of the vent tank and to condense steam which may pass-through the PCC vent without condensing. j: The vent tank shall be provided with systems to fill the tank to a predetermined level, and to ; maintain that level during a test. Provision shall be made to measure water flow rate from the vent i tank drain,in the event that condensate from the PCC is carried over in the vent line. l The vent tank gas discharge pipe shall be provided with a system to control the tank pressure by : throttling vent tank exhaust. During tests with no noncondensible inlet flow to the PCC it may be ! necessary to pressurize the vent tank by some means such as injecting air directly into the vent tank as suggested by Figure 4-1. Although the system is shown to control vent tank pressure, the , variable used for setting up the desired test conditions will be PCC inlet pressure. l 4.1.3.5 Piping. The piping for the inlet gases, condensate drain and venting shall be as i prototypical as is practical with respect to inside diameter, irreversible hydraulic losses and : elevation differences. The piping external to the PCC pool shall be thermally insulated as : necessary to: i
- 1. Minimize the heat losses to the surroundings
{
- 2. Ensure an accurate measure of the condensing capacity of the PCC.
Routing shall avoid nonprototypical opportunities for steam pocketing. The vent line shall ; include a gate valve or flanges for a blind orifice to provide capability to physically prevent venting of the PCC.

All test instrumentation lshall be provided by the Test Performer ' and shall be calibrated against standards traceable to the U. S. National Institute of Standards and ; Technology or equivalent. _4.1.4.2 Thermal-Hvdraulic. The required thermal-hydraulic measurements, the required accuracy and the proposed digital sampling frequency for the PCC are listed in Table 4-1.' The . required accuracy in Table 4-1, is given as the "two standard deviation" level of a normally ! distributed error, i.e. there is a 95% probability that the error does not exceed the specified value. Inside and outside tube wall temperature measurements are required on four tubes at nine axial , positions on each tube. The preferred tubes for these measurements are 1 A,4A,5Q and SQ. The location of these tubes in the tube bundle is illustrated in Figure 4-3. The axial locations of the measurements are shown below: Location Number 1 2 3 4 5 6 7- -8 9 ; Distance Above Tube Centerline (cm) 750 650 550 450 250 -50 -150 -450 -750

Thermocouples and lead wires shall be installed such that flow disturbances are minimized. 4.1.4.3 Structural. The required structural measurements for the PCC are listed in Table 4-2 and the numbered instrument positions identined in Figure 4-4. The positions are only indicative: the , exact locations will be defined by Ansaldo after the stress analysis. See Reference 2.2.c. The two PCC condenser modules are referred to as "A" and "B". Module B is instrumented in onlya few positions for comparison with Module A and for confirmation of symmetrical performance. The ; types of structural measurement required for the PCC are acceleration, displacement, strain, l permanent strain and surface temperature, i Acceleration measurements will be made primarily for the purpose of evaluating vibration ; characteristics and detection of possible condensation / water hammer loads. Piezoelectric accelerometers are recommended for these measurements.The required temperature range is ; 10 to 177'C (50 to 350*F). The unfiltered signals shall be recorded in analog form with a ! recorder having a bandwidth of1 -500 Hz. ' Linear displacement measurements are required at points specified in Table 4-2 with an accuracy of 0.2 mm (0.008 in). t m- - - - -

In general, monodirectional strain gages should be used to determine the total strain. j At some positions referred to in Table 4-2, multiple measurements are specified at the same [ position. All strain gages shall be compensated for temperature variations in the range of10 to l 177*C (50 to 350*F) and shall be waterproof. Permanent strain shall be measured at the locations and directions specified in Table 4-2, by surface scribe marks. The distance between scribe marks will be measured prior of testing, once during the test and at the end of the tests, to determine if there has been any permanent strain. PCC external surface temperatures shall be measured at the locations shown in Table 4-2 and Figure 4-4 with an accuracy (2 std. dev.) of 3 C (5 F) or better.The temperature range is 10 to 177 C (50 to 350 F). 4.2 Facility Renoirements for the IC 4.2.1 Principal Functions and Comnonents. A schematic diagram illustrating the essential features of the facility required for testing the IC is shown in Figure 4-5. The principal components of the test facility shall be: Simulated reactor pressur- vessel (RPV). Steam supply. Supply of high pressure noncondensible gas (es). IC pool tank. Piping and valves. The test facility must supply steam, water and noncondensible gases in quantities and at conditions which are representative of those anticipated for the SBWR IC. 1 4.2.2 Test Variables. The independent test variables are: i l Drain valve position (open or closed). IC inlet steam pressure. Noncondensible gas inlet flow rate. Composition of noncondensible gas. 1 The following variables shall be controlled: l l IC pool tank level (supply makeup to maintain constant level). IC pool tank temperature. IC pool water quality.

4.2.3 Comoonent Renuirements
. i 4.2.3.1 Steam and Noncondensible Gases. Saturated dry steam (quality greater than 99.8%) shall be supplied to the IC at a controllable pressure in the range 0.48 to 9.48 MPa gage (70 to 1375 psig). Available continuous steam flow rate shall be at least 14.3 kg/s (31.6 lb/s) at 8.618 MPa ' l gage (1250 psig) (based on 20 MWth). 1 4
Provision shall be made for injection of noncondensible gases (nitrogen or air and helium) into ! the IC steam supply at a controlled and measured rate. The noricondensible gases will be injected l at steam pressures in the range 0.48 to 8.618 MPa gage (70 to 1250 psig). The gas supplies shall - j be sized such that the Isolation Condenser can be filled with the gas at 8.618 MPa gage (1250 psig) in one test period. j i The possible need to provide the capability to heat the noncondensible gases or the gas / steam l mixture shall be considered. , 4.2.3.2 IC Pool Tank. The IC pool tank shall be a rectar. gular elevated tank, open to the _ j atmosphere, for the purpose of containing the IC and the water which cools it. The tank shall be ! large enough and have provision for internally attaching, with prototypical mounting hardware, a l full-scale, single-module IC test unit (one-half of a full unit), and prototypical inlet, vent and ' condensate drain piping. The upper steam header and upper steam pipe transition fitting shall be fixed so as to prevent sliding in the horizontal direction to simulate worst case support ! conditions, j The pool depth shall be sufficient to submerge the IC to a prototypical water level. The required : dimensions for the IC test pool are shown on Figure 4-6. The pool shall be covered, and shall l have an open area for venting pool boiloff. The open area of the vent shall be at least 1 m2 1 2 (10.8 ft ) and not more than 5 m2 (54 ft2 ).
)~
The IC Pool Tank shall be provided with systems to fill the pool with highly purified water prior to a test, to replace boiloff and maintain constant water level and temperature during a test. Systems shall be provided to cool the pool inventory between tests and to drain the pool for 1 maintenance or modifications to the IC. The water quality requirements for the IC pool are -;
- shown in Table 4-5. /!
The makeup water system shall be sufficient to replace pool boiloff and water entrained with the steam and to maintain a constant pool level at the maximum condensation rate for a period of at ; least 4 hours. Pool boiloff (no carryover) with 20 MWth heat transfer was calculated to be approximately 9.3x10-3 m3/s (147 gpm). The makeup water shall be the same quality as the pool : water, It shall be distributed in the pool such that non-prototypical flow patterns and temperature I distributions are avoided. l L The pool cooling system shall provide for control of pool heatup and cooldown rates typical of SBWR to adequately simulate the design thermal cycles. l l l I

. (RPV) and supply saturated steam to the IC. The vessel shall be partially filled with saturated water and the steam supply to the IC shall be taken from above the water level and the ;
condensate from the IC shall be returned to the vessel below the water level.The vessel shall be - heated with a source sufficient to maintain vessel pressure with maximum heat rejection by the '! IC.
.f 4.2.3.4 Pining and Valves. The piping for the IC inlet steam, condensate drain and venting shall be a: prototypical as is practical with respect to inside diameter, irreversible hydraulic losses and elevation differences. The piping shall be thermally insulated and routing shall avoid l nonprototypical opportunities for steam pocketing. j i
The condensate drain line shall have a valve for startup of the IC.The valve shall meet the ! leakage (through the valve) and opening time requirements of SBWR IC valve (see document reference in Paragraph 2.1 h.) A valve size as small as 102mm (4-inch) may be used provided the ! total IC loop irreversible hydraulic losses (piping, cibows, valves and condenser) do not c:.ceed ! 6.3 psi at the maximum flow rate (Reference document 2.1 a, note 5). The valve and opecktor ! shall be supplied by SIET. The condensate drain line shall include a loop seal of at le u.5 m (20 inches) elevation at the return to the simulated RPV. l The condensate drain line shall have a bypass line around the drain valve. The bypass line shall ! include a small valve (approximately 20mm [ 3/4-inch]) for simulating drain valve leakage. i i The steam supply pipe and the condensate return pipe shall be designed to produce a stress in ! bending which corresponds to the maximum allowable pipe bending stress of 1.5 Sm which is ! caused by combined mechanical, seismic, and thermal expansion loads at 8.618 MPa gage * (1250*psig),302 C (575 F). Direction of deflection shall be selected to maximize the resultant stress on the piping and nozzles between the transition fittings and headers. : As an alternative, guides or lugs may be provided at the lower end of these pipes, at locations to f be defined by Ansaldo. If this alternative is selected, the Test Performer shall define the load and i moment on the steam supply and condensate drain pipe connections that results from the test t facility piping arrangement. : 4.2.3.5 Vent Lines. Ventlines shall be provided on the IC from both the upper and lower plenum. Each line shall be manually controlled by a normally-closed, fail-closed solenoid valve and shall have a 12.7 mm (1/2-inch) Dow restricting orifice to limit the venting rate as in SBWR. Provision shall be made for measuring the volume of gas vented from the IC. It is expected that noncondensible gases injected into the inlet steam will separate in the IC and l eventually fill the upper and/or lower IC plenum, and reduce the heat removal capability. The l vent lines shall be used, as described in Paragraph 6.2.1, during tests to remove the ' noncondensible gases from the IC and restore capacity.The vent lines shall be actuated by l

It is desired to manually simulate the automatic venting - l scheme of the SBWR IC system during some tests (See Reference document 2.1.c.). l 4.2.3.6 Elbow Finw Meters. One horizontal elbow in both the steam supplyline and the - ! condensate drain line shall be equipped for use as elbow flow meters.These devices represent i the elbow meters used in the SBWR IC system and are notintended to be used for flow - . i measurement in the IC tests. For the SBWR IC system, the elbow flow meters will provide a j signal to indicate the occurrence of a break in the IC inlet or condensate drain lines. Their l purpose in the SIET test is to provide a measurement of the "IC startup transient" operating ! signal and noise levels. I The elbow on each of the two lines shall be the same pipe diameter as used in the SBWR IC. j Ninety-degree,long radius (R/d = 1.5), elbows shall be used and the pressure taps shall be in the outer and inner circumferences of the elbow midplane,45 degrees from the inlet end.The ! pressure tap holes shall be 6 mm (0.236 in) in diameter.There must be no burrs, wire edges or i other irregularities on the inside of the pipe at the nipple connection or along the edge of the ! hole through the pipe wall.The diameter of the hole should not decrease within a distance of12 j ' mm (0.472 in) from the inner surface of the pipe but may be increased within a lesser distance. Where the presure hole breaks through the inner surface of the pipe there must be no ; roughness, burrs nor wire edge. The edge of the hole may be left truly square or may be dulled (rounded) very slightly. . Connections to the pressure holes should be made by nipples, couplings, or adapters welded to. -l the outside of the pipe. It is important that no part of any such fitting projects beyond the mner , surface of the pipe. ; It is desirable that the velocity profile of the fluid stream entering the elbow be fairly uniform [ and free of swirls.The recommendations of the document referenced in Paragraph 2.3.b l regarding straight lengths of pipe upstream and downstream of the elbows shall be followed as - much as possible. Condensation pots shall be used on the pressure tap lines if necessary to keep l the line full of water. l 4.2.4 Instrumentation Renuirements (IC) f 4.2.4.1 General Renuirements. All test instrumentation shall be provided by the Test Performer and shall be calibrated against standards traceable to the U. S. National Institute of Standards and 3 Technology or equivalent. f 4.2.4.2 Thermal-Hvdraulic. The required thermal hydraulic measurements, the required ; accuracy and the proposed digital sampling frequency for the IC are listed in Table 4-3. The required accuracy in Table 4-3, is given as the "two standard deviation" level of"normally" ! distributed error,i.e. there is a 95% probability that the error does not exceed the specified value. l i
W GENuclearEnergy 23^6999 REV.4 su so.24 Temperature, steam Dow, condensate Dow and pressure instruments shall be provided to monitor the heatup and cooldown rates of the coolant and the heat transfer from the condenser during the thermal cycle conditions to be tested. Temperature measurements shall be made on the vertical section of steam pipe which connects to the steam header below pool water level.The purpose of this measurement is to detect condensate return valve or IC unit leakage when the IC is in the hot standby (fully pressurized) non-operating mode with the condensate return valves closed. Six temperature elements shall be located on the outside of the steam pipe spaced at 0.1m (3.9-inch). The upper element shall be at the pool normal water level elevation. 4.2.4.3 Structural. The required structural measurements for the IC are listed in Table 4-4 and the numbered instrument positions identified in Figure 4-7. The positions are only indicative: the exact locations will be denned by Ansaldo after the stress analysis of the IC. See reference 2.2.c. The types of structural measurement required for the IC are acceleration, displacement, strain, surface temperature and surface scribe marks for measurement of permanent strain. Acceleration measurements will be made primarily for the purpose of evaluating vibration characteristics and detection of possible condensation / water hammer loads. Piezoelectric accelerometers are recommended for these measurements.The required temperature range is 10 to 314 C (50 to 598 F). Linear displacement measurement is required at points specified in Table 4-4 with an accuracy of
+0.2 mm (0.008 in).
Total strain on the surface shall be determined at the locations and directions specified in Table 4-4. In general, monodirectional strain gage should be used to determine the total strain. At some positions referred to in Table 4-4, multiple measurements are specified at the same position. All strain gages shall be compensated for temperature variations in the range of10 to 314*C (50 to 598 F) and shall be waterproof. IC external surface temperatures shall be measured at the locations shown in Table 4-4 and Figure 4-7 with an accuracy (2 std. dev.) of 3 C (5 F) or better. The temperature range is 10 to 314*C (50 to 598 F). Permanent strain shall be measured at the locations and directions specified in Table 4-4, by surface scribe marks.The distance between scribe marks will be measured prior of testing, once during the test and at the end of the tests, to determine if there has been any permanent strain.

5.2 PCC Test Strateev. The PCC tests will be a series of steady-state tests at specified steam flow rate, noncondensible flow rate, inlet gas temperature and inlet pressure (equivalent to drywell). The condensate tank pressure will be equal to the inlet pressure and the vent tank pressure will be adjusted to obtain the specified PCC inlet pressure. The PCC pool will be maintained at a constant level (full) and equilibrium bulk average temperature during most tests. The PCC will be brought to the specified conditions and allowed to stabilize, i.e. reach a condition of steady-state heat transfer and allowed to operate for approximately 15 minutes at these conditions. Data will be recorded during pool heatup and for the period of steady operation.

The performance test includes most of these conditions, except for . the LOCA and the pneumatic leak testing. Definition: A.S.I. Simulated LOCA Pressurizations The design basis is two LOCAs during the sixty year design life of ti.e PCC. For the test,10-simulated LOCA cycles must be performed. General Test Procedure: The PCC is to be rapidly pressurized with saturated steam to 379 kPa(g) (55 psig) and 151*C (303*F). The vent tank discharge valve must be partly open during pressurization to purge air from the PCC tubes and permit heating. The total time period for the pressurization and data recording is approximately 30 minutes.The flow rate of steam required to achieve these conditions can be determined either by shakedown testing or from previously run two module tests. If the steam supply is not large enough to maintain the required pressure with a steam-only
. inlet flow to the PCC, air flow can be added. Pre-adjustment of the vent tank discharge valve position by " trial and error" may be necessary.

6.2.1 Descrintion of Tests 6.2.1.1. Thermal-Hvdraulic Performance Tests. The thermal-hydraulic performance tests will -{ collect data under various operating conditions of the isolation condenser. The tests are ' ; classified under the following types. The test conditions are given in Appendix B. ; i Tvne 1 - Performance Data i, i Steady-state IC operation shall be measured for at least 15 minutes at various pressures. l
\
Tvne 3 Non-condensible Gas Effect - i s After achieving the specified steady-state operation, non-condensible gas will be injected into the - 1 IC and allowed to build up. The degradation in thermal-hydraulic performance will be - measured. At a specified pressure, the gas will be vented using the top and/or bottom vent lines.' j Tvne 4m - Pool Water Level Effect i After achieving the specified steady-state operation, the water level of the IC pool will be lowered, and the degradation in thermal-hydraulic performance measured. 6.2.1.2 Structural Cvele Tests. The structural tests will essentially be representative of the cyclic duty expected of the isolation condenser as used in the SBWR. Each test will consist of a cycle ; corresponding to one of the basic types.The cycle types are described below and illustrated in Figure 6-1. initial Conditions for All Cycle Tvnes: ! 1 I The condensate drain valve is closed and the IC is filled with water.The IC' pool shall be full and ! the initial water temperature at the specified value. I Tvocs 2 and 5 " Normal"IC Oneration:
- 1. Heat up and pressurize with steam from ambient to pressure P1 at a rate of approximately j 56*C (100*F) per hour. i
- 2. Allow the system to stabilize at P1 and then open condensate drain valve. l 4

stabilize the condenser inlet pressure at P2. If the specified value of P2 cannot be sustained atl
. the maximum steam flow rate (20 hBV), then perform the test at the maximum sustainable :
pressure below P2. l
- 4. Continue steady condenser operation at these conditions for a period of time, T2.
- 5. At the end of the time period, T2, depressurize and cool down the system at -
approximately 56'C (100'F) per hour.

2.- Allow the sptem to stabilize at P1 and then increase pressure rapidly (approximately l 0.5 minutes) to P2 and open condensate drain valve.
- 3. As condensation reduces the inlet pressure, increase the inlet steam flow rate as necessary to l stabilize the condenser inlet pressure at P3. If the specified value of P3 cannot be sustained at' ;
the maximum steam flow rate (20 hnV), then perform the test at the maximum sustainable pressure below P3. !
