Fusion Energy Sciences Program Strategy: Plasma Control Science

(ITER) and Integrated Fusion Nuclear Science

U.S. ITER Project engaging Industry, Universities and National Labs

Next critical R&D opportunities: materials and internals encountering

fusion particle fluxes and fluences

Examples: from lab science to industry to energy commercialization

Fusion nuclear S&T in the ITER era: to engage Office of Science

facilities and programs, and be complemented by critical new facilitiesand international collaboration
