Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
192 words
A system for the conversion of nuclear energy to electric power which minimizes radiation contamination, thermal pollution and the danger of nuclear explosion comprising, a nuclear reactor, a steam boiler in heat exchange relation with said reactor, said nuclear reactor and boiler being located in a chamber at a distance below ground level sufficient to shield by the interposition of the earth''s crust surface areas above said reactor from nuclear radiation and sufficient to contain any nuclear explosion due to malfunction of said reactor, a shaft connecting said chamber to the surface level of the ground, a vertical conduit in said shaft for the transmission of water therethrough, a hydro-electric generator generally at the same level as said reactor connected to said conduit for receiving a descending column of water therein to generate electric power, means connecting the outlet of the hydro-generator to said boiler, steam conduit means in said shaft connected to said boiler for conducting steam generated in said boiler to said surface level, and steam turbo-electric generator means connected to said steam conduit for converting heat energy in the form of steam produced by said boiler into electrical energy.
Claim 2
Independent Claim
192 words
A system for the conversion of nuclear energy to electric power which minimizes radiation contamination, thermal pollution and the danger of nuclear explosion comprising, a nuclear reactor, a steam boiler in heat exchange relation with said reactor, said nuclear reactor and boiler being located in a chamber at a distance below ground level sufficient to shield by the interposition of the earth''s crust surface areas above said reactor from nuclear radiation and sufficient to contain any nuclear explosion due to malfunction of said reactor, a shaft connecting said chamber to the surface level of the ground, a vertical conduit in said shaft for the transmission of water therethrough, a hydro-electric generator generally at the same level as said reactor connected to said conduit for receiving a descending column of water therein to generate electric power, means connecting the outlet of the hydro-generator to said boiler, steam conduit means in said shaft connected to said boiler for conducting steam generated in said boiler to said surface level, and steam turbo-electric generator means connected to said steam conduit for converting heat energy in the form of steam produced by said boiler into electrical energy.
Claim 3
Dependent Claim
77 words
The system according to claim 1 wherein high temperature, high pressure steam turbo-electric generator means is located generally at the same level as said boiler and reactor for partially converting heat energy in the form of steam to electrical energy, and a second lower temperature lower pressure steam turbo-electric generator means is connected to said steam conduit above said surface level for converting the remainder of said heat energy in the form of steam to electrical energy.
Claim 4
Dependent Claim
46 words
The system according to claim 2 which includes a condenser located above surface level for receiving steam exhaust from the steam turbo-electric generator means, means for cooling said condenser, outlet means from said condenser and means for recirculating condensate water from said condenser to said conduit.
