1 AP600 LONG TERM COOLING TEST SPECIFICATION, REV.1 l

1

1.0 BACKGROUND

INFORMATION This test was initially designed to demonstrate the low pressue (<50 psig)long-tenn cooling phenomenon of AP600 with a quartz model. Quartz material was selected because it would provide visual resulta and because Portland General Electrie (PGE) 1 would contribute in funding such a program However, some concerns associated with the quartz model were raised about the i

model cost, the safe operation of the test and the limitation on the system pressure.

Consequently, stainless steel was selected for the followmg reasons:

(A)

Quartz model can only be run at low pressure, about 65 psia. It was felt that l

' at this low a system pressure Automatic Depressunzation system (ADS) can not be adequately simulated. With stainless steel model the system pressure can be much higher, hence ADS actuation can be simulated accurately.

(B)

Since the pressure limit on the quartz material is so low and the water temperature in the test is relatively high, the margin for the safe operation of the test is very nmall l

l (C)

The cost of the major components such as the reactor vessel,if made of quartz,

{

would be appronmately 30% of the entire test model cost. The cost ofstainless i

steel vessel would be sigmficantly less.

J (D)

With stamless steel model, the origmal test scope can be fulfilled, and l

l additional scope can be added.

INFORMATION (Continued)

incorporated to pmperly address the AP600 long term co the stainless steel model was selected in favor of th mcess. Consequently, e quartz model.

This test shall be made of stainless steel and the original f

.est ecope with the quartz model shall be maintained, except flow visualization is elimi nated. The test model shall include reactor coolant system, passive core cooling syh, steam generator system, chemical and volume control system and n 4

WESTINGHOUSE CLASS 3 2.0 PURPOSE This test is draigned to provide valid thermal hydraulic data to verify the AP600 thermal hydraulie computer codes. The data shall capture key AP600 phenomena such as gravity injection, natural convection and post-accident long term core moling behavior at various modes of operations.

To validate the AP600 thermal hydraulic computer mdee, the following features shall be incorporated in the test:

The AP600 Reactor Coolant System including the reactor vessel and internals, two steam generators, two reactor coolant pumps, the pressurizer and the connecting hot and cold legs.

AP600 passive safety features including the steam generator system (SGS) the passive core cooling systems (PXS) and the automatic depressurization system

'(ADS) shall be simulated in the test. The non-safety systems connecting to the passive safety system:, also shall be simulated. These non-safety systems

~

include normal residual heat removal system (RNS) and chemical and volume control system (CVS).

The intersetion between the passive safety features and the non-safety systems shall be investigated.

The AP600 containment sump and floodup volume shall be simulated in the test to investigate sump recirculation behavior.

i Small break lost-of-coolant-accidents (SBLOCA) and inadvertent ADS t

operation shall be simulated in the test to investigate the operation process of the AP600 passive safety features. Each of these accidents shall be simulated from the onset of the accident to the final long term core cooling mode operation.

WESTih3GrIOU55 CLASS 3 2.0 PURPOSE (Continued)

{

Each operation shall provide data to characterize the cooling Bow paths into the simulated reactor, through the core, to and out the ADS valves, steam generators, the ADS valves on the hot legs and the break in the loop piping, and other loops in the test facility.

Since this test is a low pressure integral system test, it will provide data to validate the low pressure range of the computer code. The high pressure data will be provided by the SPES test in Italy. However, this test shall provide data at a pressure i

overlapping the SPES test.

Troes of Instrumentation It is important to define all the mrtrumentation that may be reqmred to obtain t

a mass / energy balance in the test facility prior to constnietion of the loop.

Allowances for installation of instrumentation, such as taps for differential pressure transducers, can then be installed durmg construction in the event they

' are reqmred in the future. Table 1 is a praliminary list of the instrumentation.

It is by no maans a complete list since more may be added in the future as needed.

However, it does serve the measunng purpose for those tests listed in Section 9.0.

The following types ofinstrumentation are to be provided for the AP600 Long Term Cooling Test:

Thertnocouples (T/C's) ahall be used to measure the temperature of the coolant in the primary and secondary systems as well as any supply or component cooling water. They also measure selected component wall and msulation temperature in ortler to complete mass / energy balance on the component.
