Summary:A preliminary examination is made of several potential safety questions for Tokomak-type, central station fusion power reactors, using UWMAK-I as a reference concept. Larger tritium inventories than previously reported are estimated. The divertor loss-of-flow accident appears to require fast plasma shutdown. The large helium inventory in the cryogenic magnets affords a mechanism for generating large pressures within the containment. Lithium-air and lithium-concrete reactions have the potential for generating large amounts of heat, significant pressures, and active chemical species capable of volatilizing structural material such as a radioactive first wall.
