1.0 IIA C K G R O U N D The Bench Scale Wind Tunnel Tats of the Passive Containment Cooling System (PCCS) were conducted in 1987 at the Westinghouse Science and Technology Center, Pittsburgt , PA to support the AP600 conceptual design program. Tests were performed on models of the AP600 shield building, air inlets and outlet, annulus baffle, and co Jainment to establish the proper location of the air inlets on the shield building, and to confirm that with the proper air inlet / exhaust arrangement, wind can always aid containment cooling air flow. Two models were utilized: one consisted of only the shield building and diffuser discharge without inlets and internal flow; the second included the air inlets, air baitt :, containment, tank support structure and a fan to simulate convective air flow. Pressures were measured at the inlet, the building side and top, the bottom of the inlet annulus, the top of the containment at the oischarge of the air baffle, and in the chimney Air flow was measured at the inlet to the containn.ent baffle. These tests were run with a uniform wind tunnel air velocity of 85 f t/see and test Reynolds numbers for the shield building and chimney were demonstrated to be in the transition region. The models used in this test were 10-inches in diameter and 18-inches in overall height. Figure I provides an assembly drawing of the medel which included the containment and air baffle structures, and also shows the location of Static Pressure Taps (SI'Ts) and air velocity (anemometer) measurement. The instnimentation was located in a common vertical plane and the model was rotated through 360 degrees to obtain the air pressure profile around the entire structure.

2.0 TEST RESULTS i
The results from this test are illustrated in Figures 2 and 3. Figure 2 is typical of data collected using 1 1
the simple model of the shield buikling without air inlets, containment, or cooling air baffle around the containment. Static air pressure at several locations on the shield building structure are shown versus the air pressure in the air exhaust structure. This figure illustrates that when the air inlets are located on the top (roof) of the shield building, a " chimney" effect is created over a significant portion of top of the building (this effect became more pronounced when the wind direction was inclined upward);
and air inlets located at the top of the shield building sidewalls overall provide the most positive wind induced driving pressure versus air exit pressure.
Figure 3 illustrates the typical air pressure profiles developed within the shield building across the cooling air baffle to the air exit with external wind. By comparison to a "no-wind" case where all the cooling air flow was induced by the fan, it was shown that with the selected air inlet arrangement the wind always will increase the containment cooling air flowrate.

3.0 CONCI,USIONS The signincant conclusions from this test are summarized below:
- The observed air pressure just within the shield building air inlets was approximately equal to the average value of the air velocity head measured around the outside of the shield building.
-
- Deep beams behind the air inlets (as provided in the PCCS water storage tank structure) significantly increase wind induced containment air cooling now.
- The containment air cooling How is insensitive to wind direction and to 15 degree downward wind inclinadon. Cooling flow is increased by a 15 degree upward wind inclination.
- An inlet on the side of the shield building (at the top) aides containment cooling.
- An inlet on the top of the shield building should be avoided.
- The chimney pressure coef0cient varies from -0.6 (no flow) to -0.35 (max flow) through the cooling annulus.
