Abstract
A means for and method of producing and retaining tritium utilizing lithium bismuth and nickel is disclosed herein. The lithium bismuth serves to produce the tritium when exposed to neutrons. The nickel serves to dissolve and thereby retain the tritium which is produced by the lithium bismuth. As disclosed herein, both of these materials are contained within a common tubular housing which is pervious to the neutrons but impervious to any tritium which is produced therein.
Claims8
An arrangement for producing tritium and retaining substantially all of the tritium so produced within the environment of a fast breeder reactor which provides a supply of neutron radiation during operation thereof, said arrangement comprising:
- (a) means forming part of said fast breeder reactor for producing neutron radiation;
- (b) a housing which is pervious to said neutron radiation at least to a limited extent and substantially impervious to tritium, said housing being located within said fast breeder reactor such that its interior is subjected to said neutron radiation during production thereof within said reactor;
- (c) a volume of lithium bismuth material contained within said housing and thereby subjected to said neutron radiation during the production thereof, whereby to produce tritium;
- and
- (d) a sufficiently large volume of nickel material contained within said housing and disposed sufficiently close to said lithium bismuth so as to retain substantially all of the tritium produced by said lithium bismuth.
A method of producing tritium and retaining substantially all of the tritium so produced within the environment of a fast breeder nuclear reactor which provides neutron radiation during operation thereof, said method comprising:
- (a) providing a housing which is pervious to said neutron radiation at least to a limited extent and substantially impervious to tritium;
- (b) placing within said housing a volume of lithium bismuth material and a volume of nickel material, the nickel material being positioned relative to the lithium bismuth material so as to capture and retain tritium produced by said lithium bismuth material, said nickel material being of sufficiently large volume so as to capture and retain substantially all of the tritium produced by said lithium bismuth;
- and
- (c) placing said housing containing said lithium bismuth and nickel material within said fast breeder reactor such that the lithium bismuth within the container is subjected to said neutron radiation, whereby the lithium bismuth produces tritium and the nickel material captures and retains substantially all of the tritium so produced.
