Pressurized-Water Cooling-Tube Ruptures in a Fusion Blanket

摘要

Recent fusion-reactor conceptual designs include pressurized water as the coolant for the first wall and blanket. To determine design adequacy, the consequences of a pressurized-water cooling-tube failure within the blanket have been analyzed using the time-dependent computer code ATHENA. The ATHENA code, being developed by EG and G Idaho, Inc., simulates safety-related transients in fusion blankets, first walls, and other reactor systems. The analysis showed that some blanket design modifications must be made to ensure module integrity following an internal cooling-tube break. (ERA citation 08:042997)
