Section: claims

1. A glass pool nuclear reactor comprising: an energy using means for utilizing thermal energy from the reactor;  a reactor capsule having a heat radiating outer shell and a neutron reflecting inner shell;  a fission core centrally located within the reactor capsule having a rich thorium/U.sup.233 composition;  a glass pool, heat sink encompassing the core comprised of a glass and fertile thorium fuel matrix with a thorium content diminishing from the core to the inner shell of the reactor capsule; wherein,  the glass and fertile fuel matrix is in a molten state during operation of the reactor and is in a solid state on termination of operation of the reactor. 2. The reactor of claim 1 wherein the outer shell of the reactor capsule has heat radiating fins. 3. The reactor of claim 2 having further a pressure vessel encompassing the reactor capsule the pressure vessel having an inlet and an outlet. 4. The reactor of claim 3 wherein the energy using means comprises a closed gas cycle, power plant, the plant having a gas compressor, a turbine connected to the compressor and a gas collector with return means for cycling gas from the turbine to the compressor and delivery means for delivering compressed gas from the compressor through the pressure vessel and to the turbine. 5. The reactor of claim 4 wherein the energy using means includes further, an intercooler and the delivery means includes bypass means for delivering part of the compressed gas from the compressor through the intercooler and to the collector wherein hot and cold gases discharged from the turbine are mixed. 6. The reactor of claim 5 wherein a majority of collected gas in the collector are returned to the intercooled compressor. 7. The reactor of claim 3 wherein the energy using means includes further, an intercooled compressor, wherein the intercooled compressor is a staged compressor with intercoolers after each stage and with delivery means for delivering compressed cool gas directly to the turbine wherein the return means includes a first return path from the gas collector to the gas compressor and a second path from the gas collector to the intercooled compressor. 8. The reactor of claim 7 wherein a majority of collected gas in the gas collector is returned to the intercooled compressor. 9. The reactor of claim 5 wherein the reactor capsule has a fuel supply conduit with a plug, and a core container means for receiving fuel balls from an external supply through the supply conduit. 10. The reactor of claim 9 wherein the fuel supply conduit includes means for insertion of a probe means for emitting a photoneutron generating beam to stimulate fission of fuel balls contained in the core container. 11. The reactor of claim 9, wherein the core contains fertile thorium fuel balls that are transformable to a fissionable material on stimulation by a photoneutron generating beam. 12. The reactor of claim 9 wherein the plug contains a neutron absorbing material that terminates fission and operation of the reactor when the plug is lowered into the core. 13. The reactor of claim 3 wherein the pressure vessel is contained within an outer containment structure. 14. The reactor of claim 1 wherein the reactor capsule is spherical in configuration. 15. The reactor of claim 3 wherein the pressure vessel is spherical in configuration. 16. The reactor of claim 1 wherein the reactor capsule is spherical in configuration and is contained within a spherical pressure vessel. 17. The reactor of claim 16 wherein the spherical pressure vessel has a geometric center displaced from the geometric center of the reactor capsule. 18. The reactor of claim 17 wherein the spherical reactor capsule has fins and the inlet and outlet are arranged such that the surface area of the fins increases as the gas passes from inlet to outlet. 19. The reactor of claim 4 wherein the energy using means uses air in the closed gas cycle.
