ARIES-CS is a 1000 MW(electric) compact stellarator conceptual fusion power plant design. This power plant design contains many innovative features to improve the physics, engineering, and safety performance of the stellarator concept. ARIES-CS utilizes a dualcooled lead lithium blanket that employs low-activation ferritic steel as a structural material, with the first wall cooled by helium and...

As part of the pre-conceptual design activities for European DEMOnstration plant, a carefully selected set safety analyses have been performed to assess plant integrated performance and capability achieve expected targets while keeping it in safe operation domain. The DEMO divertor is in-vessel component charge exhausting major plasma ions’ thermal power region far from core control pollution. ...

Power reactor oriented thermal-hydraulic research, from the safety viewpoint, has been dominated over the past thirty years by accident considerations. The postulated loss of coolant accident, and severe accident concerns, have been the focus of world-wide research programs whose cost is undoubtedly measured in excess of a billion dollars. Various actual accidents, notably Three Mile Island and...

Detailed activation, decay heat and waste disposal calculations of the ARIES-AT design are performed to evaluate the safety aspects of the device. The high initial activity of the SiC highly irradiated components translates directly into a higher initial decay heat for these structures than for the well-protected steel-based components. However, after a one-hour cool-down period, the SiC decay ...
