There are thus severe constraints on the long run potential of nuclear energy for generating electricity unless new nuclear fuel is "artificially" produced. Such fuel can be produced through the process of "breeding" within a "fast breeder reactor." The fast breeder reactor differs from the now common light water nuclear reactor in that the neutrons which split atoms in the fuel (thereby releasing new neutrons and heat energy) travel much faster than the neutrons in ordinary reactors. The reactor breeds new fuel through what has aptly been termed "a sort of modern alchemy." 2 Some neutrons leave the inner core of the reactor, which is made up of fissionable Uranium-235, and enter a blanket of nonfissionable Uranium-238. When atoms in this blanket are struck by neutrons, they are transmuted into Plutonium-239, itself a fissionable fuel which can be removed from the reactor and used in other installations. It is estimated that after about 10 years of operation the typical fast breeder reactor will produce enough fissionable Plutonium-239 not only to refuel itself completely, but also to fuel an additional reactor of comparable size. The Liquid Metal Fast Breeder Reactor (henceforth LMFBR) is simply a fast breeder reactor that uses a liquid metal, sodium, as a coolant and heat transfer agent. Because the breeding principle makes possible vast expansion of fuel available for nuclear reactors (Uranium-238 is many times more common than Uranium- 235), it has been the subject of considerable interest since the earliest days of atomic energy. The Commission demonstrated the feasibility of breeder reactors by constructing several experimental breeder reactors in the 1950's. In its 1962 Report to the President on Civilian Nuclear Power, the Commission specifically recommended that future Government programs include vigorous development and timely introduction of economic breeder reactors which, in the Commission's view, were essential to long-range major use of nuclear energy.3 By 1967, when the Commission supplemented its Report to the President, the LMFBR had been singled out as a priority program representing the largest civilian power development area.4 ' The Commission's focus expanded beyond solving the technical problems posed by the LMFBR, and began to embrace efforts to build an industrial base and obtain acceptance for LMFBR plant types by utilities, primarily through planned Government-assisted construction of commercial scale LMFBR electrical power plants.5 In sum, the Commission •came to see its program as serving "as the key to effecting the transition of the fast breeder program from the technology development stage to the point of large-scale commercial utilization." 6 In furtherance of these objectives the Commission, in 1968, issued a 10-volume LMFBR Program Plan, the dual objectives of which were (1) to achieve, through research and development, the necessary technology, and (2) "to assure maximum development and use of a competitive, self-sustaining industrial LMFBR capability."' With growing concern about a possible energy crisis, 2. See Power Reactor Development Co. v. Int. U. of Elec., Radio & Machine Wkrs., 367 U.S. 396, 399, 81 S.Ct. 1529, 6 L.Ed. 2d 924 (1961). 3.
