Peng presentation: “Fusion Nuclear Science Facility (FNSF) – Motivation, Role, Required Capabilities” advprojects.pppl.gov/Roadmapping/agenda.asp Fusion Sci Technol 2011 vol. 60 (2) pp. 441-448
Fusion landscape will change in 5 years: • FNSF objective: Provide a continuous fusion nuclear environment of copious neutrons, to develop experimental database on nuclear-nonnuclear coupling phenomena in materials in components of plasma-material interactions, tritium fuel cycle, and power extraction. Including: • To maintain plasma T and n profiles and purity for ~106 s (12 days) – divertors capable of handling peak heat flux 10 MW/m2 and control the plasma density continuously using fueling, pumping, heating and current drive.
