Abstract:

The main mission of China Fusion Engineering Test Reactor is (1) to produce significant neutrons to demonstrate tritium self-sufficiency with breeding blankets; and (2) to generate reactor level fusion power at steady-state and high duty factor. CFETR is the penultimate step to a fusion pilot plant (FPP). In this talk, starting with two possible high field FPPs and using a rollback approach, we establish the physics requirements for CFETR. Since CFETR shares the same physics as the FPPs, a successful CFETR will confirm the feasibility of the FPP physics performance. Using integrated 1.5D modeling, we investigate a steady-state, reversed shear scenario and a long-pulse, hybrid mode scenario. The predicted performance is compared with the requirement to identify key issues that need further resolution. Several outstanding areas have been identified, including the compatibility of core-pedestal-edge and a robust radiative divertor. Engineering constraints will limit the choice of plasma shape and auxiliary heating power. The impact of resistive wall mode (RWM) and Alfven eigenmode (AE) will also be discussed.

Vincent S. Chan – 简介

After receiving his Ph.D. at University of Wisconsin-Madison in 1975, Dr. Chan joined General Atomics in San Diego, California, USA as a research scientist in fusion energy development. He became director of Core Physics at the DIII-D fusion facility in 1991 and director of Theory and Computational Science in 1998. His research interests include wave heating of plasmas, wave-particle interaction, plasma transport and design of fusion energy systems. After his retirement from General Atomics in 2014, he accepted a position as international visiting professor at University of Science and Technology of China, heading a national team engaging in the physics design of China Fusion Engineering Test Reactor.

Dr. Chan was elected a fellow of the American Physical Society (1988), chair of the American Physical Society-Division of Plasma Physics (2007), and US coordinator of the US-China magnetic fusion research collaboration (2001-2014). He received the China International Science and Technology Cooperation Award (2009), the Distinguished Achievement Award from University of Wisconsin-Madison, College of engineering (2011), and was elected an Overseas Expert, Chinese Academy of Sciences (2015).
