Page 6 00 Introduction After Test M3 has been run based on the procedure ALPHA-520 Rev.0 and after modifications of the Test Procedure Rev.1, the current document (ALPHA-520 Rev.2) describes all test phases for Transient Tests M3A, M3B and M4, including preconditerung processes. Assuming that the startmg point for the preconditioning is an empty facility at atmosphenc conditions, this procedure gives sequences of processes, which do rot need to be stncidy followed during the preconditioning process, at the discretion of Test Engsneer. Roquered phases are listed in the Checidist and must be recorded when conducted.
The current procedure gives guidance on how to proceed to bring PANDA to the required initial test condstons for a extreme case (from a cold and empty facility). The order of preconditioning sequences may be modified if needed, and single phases may be adapted to the actual condihons. Heating power indicated in preconditioning phases is theoretcal and considered as basis for time estimation; the given values cuiisi pcid to the hsghest heater performance. Due to PSI electrical power limitation or modification in preconditoning process, the heating power may be reduced.
In any case, the foreseen preconditioning process is to start with the Suppression Chambers conditioning after the facility has been set ready for operation. It continues with the GDCS tank,.
all PCC/IC condenser pools and the Drywells. Just before test initiation, the RPV is set up to satisfy the required initial conditons The test is then conducted during 20 haurs under automatic power control and without any operator actions except for those actons required to mamtain IC and PCC poollevels.
A time estimation for the preconditioning of an empty and cold' facility is given for each componentin the following table.
Test Plan Specifications are described in the GE document 25A5764 REV.2.
Note.. Since temperatures are given in Kelvin in the Test Plan Specification and in *C in the i
PANDA DAS, they are indicated in both units in that current procedure.

- The pressure and temperature defined for the PCC/lO Pools correspond to saturation values at usual atmospheric pressure at the test site.
" The first given value corresponds to the Test M3A and the second to the M3B Test.
10 Initial Alignment i
Before starting any preconditioning process, the facility is set into the specific state which establishes operations from the control room. The configuration is set in order to avoid any l
unintentional hardware manipulation during testing or preconditioning. The Data Acquisition and Control System must be property initiated and brought into operation. Valves are aligned in
. accordance to STARTUP Status, automatic heat power regulation files are loaded and the 1
auxiliary water system is filled to allow pump operation.
Five different preparation phases are needed for the Transient Tests: phase n*11 starting Control and Data Acquisition Systems, phase n*12 for the initial valve se*
phase n*13 for the configuration checking, phase n*14 to prepare the automatic heat powo.agulation and phase n*15 for e>milary water system filling.

Record on attached checidist 20 RPV Setup for Vessel Preconditioning As the heat source for the whole preconditioning process, the RPV must be capable of producing steam for vessel heating or providing hot water to the auxiliary system. In order to establish conditions to generate steam, the RPV is first heated to 373K, while most of the air is purged by venting to the atmosphere. Not all air is purged at this temperature, but that does not affect vessel preconditioning. Pure steam conditions are only required for the tests. Then the RPV is heated to about 440K to supply the auxiliary water system heat exchanger.
The RPV water level is set before preconditioning to anticipate evaporation occuring during heating by steam injection; it should reach the required Test water level at the end of the preconditioning process. However in any case it must be lower than the main steam line inlets to avoid water hammer.

The required temperature is a homogeneous temperature of 352K for the pool water as well as for the gas space. The total pressure, considering saturated conditions, is at 285kPa, which includes an air partial pressure of 240kPa The Suppressen Chambers Setup starts with water filling and pool conditioning (phase n' 31),
corenues with gas space heating by steam injection keeping 1 bar air partial pressure inside the vessels (phase n' 32). The total pressure is then set up by injectmg air with the auxiliary air system (phase n' 33). Phase n' 33 is performed during phases n' 31 and 32.

40 GDCS Heating i
The Test initial Conditions require a water level in the GDCS tank of 10,7m above the PANDA heater bundle, corresponding to a water level of 0,0m from the bottom of the tank, taking into account a full GDCS Retum Line. The required temperature is a homogeneous temperrature of 333K for the whole tank, which is achieved by filling with water up to approximately Sm at the required temperature and then draining the tank. The total pressure, under saturated conditions and in equilibrium with the Drywell pressure is at 294kPa, which includes an air partial pressure of 274kPa.
The GDCS Setup starts with structure heating by steam injection (phase n' 41), continues with water filling and pool conditioning, while keeping the vessel isolated, the air is not vented to the atmosphere as long as the total pressure is lower than 10 bars (phase n' 42).
The total pressure is then adjusted by injecting air through the auxiliary air system or by venting air to the atmosphere (phase n' 43). That last phase is performed after water has been drained and transferred to the PCC pools.

}
The Test initial Conditions for all PCC Pools and the IC Pool are the same; water level from the top of the PANDA hester bundle is defined at 23,2m, which corresponds to a water level of 4,4m in the pools. In order to anticipate the effect of evaporation during pine,dr ang, water is filled up to 4,6 m. The end Doint temperature is near the Saturation temperature for atmosphenc pressure.
l The Pools Setup is performed as follows: water is filled at the highest possbie temperature j
(phase n*51,61,71 & 81) and the temperature conditions are adjusted then by circulation through the auxiliary heat exchanger (phase n*111,112,113 & 114).
Note: Pools can be connected together and filled at tlee same time and water circulation can be also performed with connected pools.

90 Drywells Setup The nominal Drywell condition is no water, the atmosphere is a mixture of steam with a small amount of air. The total pressure considered at saturated condition is defined at 294kPa, which includes an air partial pressure of 13kPa. The required temperature being homogeneous in the whole gas space, corresponds to 404K.
The Drywells Setup consists of steam injection to heat the gas space (phase n' 91) and of a depressurization by venting to atmosphere (phase n' 92). In order to get homogeneous temperature in the vessels, air is purged during phase n'91 and 20kg of air is reinjected to the Drywells in order to satisfy the required air partial pessure of 13kPa.
During the heating process, the RPV, used as steam source, is cooled down in order to approach the required test initial conditions - heater power is controlled in order to decrease the RPV temperature.

100 RPV Initial Conditions Setup for Test After having used the RPV as heat source for vessel preconditioning. it might be at conditions different from these required for test initiation; water level, pressure and temperature may need to be adjusted in order to satisfy the test initial conditions, However, the whole preconditioning anticipates the final state; start conditions are defined in order to get RPV conditions after other vessel preconditioning close to the required test initial conditions for the RPV.
Phase n' 101 starts with a parameter monitoring, which will give the basis for acqusting of RPV conditions.

101.1 Adjust Test initial Conditions in RPV Assuming saturated conditions and a negligible air partial pressure, the pressure is set by adjusting the temperature. Cooling is achieved by supplying cold water and/or by venting steam to the atmosphere. Heating is performed by using RPV heaters. Any required action is allowed to set up the RPV test initial conditions to match the required tolerances (ref. GE document " Test Plan Specification").
1 110 Test Conditions Setup PANDA preconditioning has been now performed and the state of the facility is close to that required for test initiation; conditions out of tolerance must be adjusted to the defined values.
The test condition setup starts with the adjustment of both Suppose.On Chamber (SC) Pools (phase n' 111) and continues with the SCs gas space setup (phase n*112). The GDCS tank is then adjusted to its defined test initial conditions (phase n*113), before adjusting conditions of both Drywells (phase n' 114). The test condition setup continues then with the PCC/lO Pools condition adjustment (phase n' 115, 116, 117 & 118), which can be performed simultaneously.
All these phases are not defined in detail, allowing any required action to get the test initial conditions established.

120 Test The facility satisfies now the required test initial conditions and must be configured according i
to the test configuration described in GE document " Test Plan Specification". Due to the relatively quick test initiation, data recording is started (phase n*121) before setting the desired RPV conditions (phase n*122) and before setting the test configuration (phase n*123). That last phase should not affect the PANDA conditions, but in order to assure test initial conditions satisfying the defined tolerances, the duration of all these phases between the test configuration setup (phase n*123.1 to n' 143.9) and the test initiation (phase i
n*123.10) should not exceed a few minutes (-5 min). After test initiation, the test initial conditions must be within the tolerances given in phases n'120 and 122, in order to satisfy the acceptance criteria defined in the GE document " Test Plan Specification". If test initial conditions do not satisfy the above mentioned acceptance criteria, the test is interrupted, the heat power is shut down (phase n' 132.0), the vessels are isolated (phase n' 132.1) and the procedure starts again with the Test Conditions Setup (phase n' 110).
Due to the excessive pressure differences between vessels during the preconditioning, the pressure difference transmitters lineup (valve in) must be performed after the facility has test initial conditions established; it is performed during test configuration setup (phase n*123.7).

ALPHA-520-2 ALPHA-520-2 Page 28 Page 28 123.16A TEST M3A - PCC Pool Level Maintenance Level maintenance in Pools means, in case M3A, to keep the water level of each Pool in the domain defined by the nominal level and the specific tolerance. That level maintenance is performed as follows: Pool levels are monitored and when one approachs the lowest acceptable limit (' Lower Warning Level'), water is filled up to higher possible level (" Upper Warning Level").
Pool levels are continuously watched on and separately readjusted when required. It is expected to readjust levels every two hours during the Test duration; this periode may be different.
' Warning Levels' are inside the domain defined by the Test initial Conditions and their respective Tolerances, are close to the respective upper and lower limits but are far enough from critical levels in order to anticipate the duration of required level maintenance operations.
