High Temperature Gas Reactors

(NUREG-1338) was written in early 1989. During the late 1980s, the modular HTGR was considered by DOE as one of two possible reactor technologies for materials production (Goodjohn 1991). Preliminary design work was performed on this modular HTGR-NPR, but the plant, originally expected to start in 1998, was never built (Hoffman and Mears 1991).
