Uranium 233 37. Production of small quantities of U-233 at Hanford and processing at Oak Ridge are continuing. In view of the limited quantities of U-233 presently available, it is believed that more information can be obtained by detailed non-destructive experiments than by a test shot, and a full scale test is not planned at present. 38. It is.estimated that the value of one gram of U-233 in oo standard implosion weapons (less than 100 kilotons) is about the same as that of. DELETED of plutonium. U-233 may have usefulness for weapons gD pss Estimates of the cost of U-233 indicate that this substitution could be made only at an appreciable increase in the dollar cost per unit of explosive force delivered to a target. 39. DOE ARCHIVES Production of U-233 in sufficient quantities to make this application attractive would protably require the construction of a converter-type reactor, and special separations plent, which would produce U-233 from thorium by burn-up of U-235 obtained from gaseous diffusion plant operation. 40, Further studies of the nuclear end weapon prorerties of U-233 are being made.
