Prospects in the United States for deploying breeders on a large scale were bright when it was beHeved that rich uranium ore would be quickly exhausted as use of nuclear power expanded. The expected demand for uranium was not realized, however. Moreover, the utiliza tion of breeders requires reprocessing (39). In 1979 a ban was placed on reprocessing in the United States. A dampening effect on development of that part of the fuel cycle for breeder reactors resulted. The CRFBP was canceled and France and Japan became leaders in breeder development.

This concept later evolved into the Ucarsep membrane made of a layer of nonsintered ceramic oxide (including Zr02) deposited on a porous carbon or ceramic support, which was patented by Union Carbide in 1973 (Trulson and Litz 1973). Apparently, the prospects for a significant industrial development of these membranes were at the time rather limited. In 1978, Union Carbide sold to SPEC the worldwide licence for these membranes, except for a number of applications in the textile industry in the U.S. At that time, SPEC recognized the potential of inorganic membranes, but declassification of the inorganic membrane technology it had itself developed for uranium enrichment was not possible.

Unenriched uranium—which contains more than 99 percent of the nonfissionable isotope U-238—undergoes a chain reaction only if it is mixed with a moderator to slow down the neutrons. Uranium in ore is mixed with other substances that impede the reaction and has no moderator to slow down the neutrons, so no chain reaction occurs. 75- Nuclear fission is a poor prospect for powering automobiles primarily because of the massive shielding that would be required to protect the occupants and others from the radioactivity and the problem of radioactive waste disposal. 

About 20 percent of the nation s electricity is produced by nuclear power plants, which consume uranium. Low-cost uranium for nuclear reactors is currently very plentiful in the United States and elsewhere in the world. Very few nuclear reactors are being built these days, so little exploration for uranium has occurred in recent decades. However, a nuclear revival, whether for electricity or hydrogen, would spur uranium prospecting and might cause uranium prices to escalate in the long term. 

The decisions on building the current NPPs in Finland were made in late 1960 s - early 1970 s. At that time, the prospects for nuclear energy were very promising and spent fuel was regarded as an asset due to the worth of its plutonium and uranium as nuclear fuel. Accordingly, the contract for the supply of the Loviisa NPP included clauses for the return of spent fuel to the supplier of the fresh fuel in Soviet Union. Though no such stipulations included in the supply contracts for the Olkiluoto NPP, it was taken obvious that the operator would later make contract with a French or British reprocessing company.

The deposits with over 130 /kg uranium have up to now, as a result of lack of economic interest, hardly been prospected for. The figures given in Table 6.3-1 have been estimated on the basis of general dependencies between concentration and the size of the deposit.

In some of the most successful work of its kind described. Cannon (1964) used two botanical methods of prospecting in the Yellow Cat area of Utah. The first involved the analysis for uranium of juniper needles and leaves of shrubs, and the second the mapping of the distribution of indicator plants. Cannon found two selenium indicators Astralagus preussi and A. pattersoni to be excellent indicators of mineralized ground.

The important point for Dunning, the reason for his passion, was that if U235 was responsible for slow-neutron fission, then its fission cross section must be 139 times as large as the slow-neutron fission cross section of natural uranium, since it was present in the natural substance to the extent of only one part in 140. By separating the 235 isotope, Herbert Anderson emphasizes in a memoir, it would be much easier to obtain the chain reaction. More than this, with the separated isotope the prospect for a bomb with unprecedented explosive power would be very great. ...
