Preliminary design of China ITER TBM with helium-cooled and solid breeder concept

ITER will play a very important role in first integrated blanket testing in fusion environment. Some DEMO blanket relevant technologies, such as tritium self-sufficiency, extraction of high-grade heat, design criteria, safety requirements and environmental impacts will be demonstrated in ITER test blanket modules (TBMs). China has planed to develop own-favored ITER TBM modules based on China's fusion energy development strategy and DEMO definition for testing during ITER operation period. He-Cooled Solid Breeder with FS is main stream for the fusion reactor blanket design and has foundation of the world R and D database. The helium-cooled solider pebble bed (HC-SB) concept has been adopted as one of option of China ITERTBM design. The preliminary design and analysis have been carried out recently. (author)
