PCCS Heat Exchanger Test
PCCS is new feature; extensive testing
PCCS heat exchanger testing was done in Italy in same facility used for ICS HX testing
Because of lower power, both halves of full-size unit could be tested

Isolation Condenser Testing
ICs are used in BWR/2s & 3s
• Dresden 2/3
• Oyster Creek
• Nine Mile 1
• Tube and shell configuration
ESBWR is same in principle, but different geometry
• One full-scale half unit tested
over wide range of operating
conditions
