Title: Gas Cooled Ceramic Power Breeder Reactor: Reactor Design and Feasibility Problem

Technical Report ·
DOI:https://doi.org/10.2172/4382001· OSTI ID:4382001

A design study is made of a central station nuclear power plant utilizing a compact, direct closed cycle gas turbine system with helium as the working fluid. The system is designed for a net electrical power output of 60 Megawatts. A terminal efficiency of 40% can be achieved with the closed gas cycle operating at 1000 psi pressure and 1400°F turbine inlet temperature, requiring a heat out-put of 150 Megawatts from the reactor. The reactor is designed within a pressure shell of 11 feet $$^{1}/_{2}$$ inch maximum outside diameter. The core contains uranium and thorium silicides in silicon carbide - silicon plate type fuel elements mounted in a graphite moderator. The active core is a right circular cylinder 6.5 feet in diameter by 6.1 feet in length. A breeding blanket, 1.5 feet thick, made up of Th02 blocks surrounds the core. An initial loading of 40 kilograms of uranium-233 is planned, for an average thermal neutron flux of 1.65 x 1014 n/cm2 sec at 25% burnup. The conversion ratio is 1.087 initially and 0.927 end of the 73 day full power operating cycle. Means are provided to minimize contamination of the system due to fission product leakage. The major problem to be solved appears to be the chemical processing of the fuel elements. The power cost from the system is estimated to be 7.6 mills/KWH which compares favorably with other immediately practicable nuclear power systems of this size.
