The Homogeneous Reactor Experiment--a nuclear pilot plant for the production of electricity with an aqueous solution of uranium as fuel--has been operated by the Oak Ridge National Laboratory over a two-year period. The heat producing chain reaction occurred in an 18-inch diameter sphere, and heat was removed by pumping the liquid fuel through a U-tube heat exchanger where steam was generated and fed to a small turbine generator unit. When the reactor was operated at 1000 Kw heat output at 250 degrees Celsius and 1000 psi, a sufficient quantity of 200 psi steam was produced to generate 140 Kw electricity. The inherent safety of the reactor, as a result of its large negative temperature coefficient, was demonstrated by increasing the power by a factor of 10(+6) in one second. Although no mechanical control devices were used, a safe equilibrium condition was reached in 100 milliseconds. Figures are included.
