Candidates for leadership provide statements: ANS Board of Directors
With the annual ANS election right around the corner, American Nuclear Society members will be going to the polls to vote for a vice president/president-elect, treasurer, and members-at-large for the Board of Directors. In January, Nuclear News published statements from candidates for vice president/president-elect and treasurer. This month, we are featuring statements from each nominee for the Board of Directors.

In six experiments using fluidized-bed fluoride volatility techniques to process irradiated uranium-Zircaloy and uranium-aluminum alloy fuels, less than 1% of the uranium was retained in the reactor and filter beds. Decontamination factors for Ce, Sr, Cs, Ru, Sb, Zr, and Nb ranged from 3.5 × 105 to 1 × 108 but were 5.9 × 104, 44.6, 3.5, and 2.9 for Te, Mo, Np, and Tc, respectively. Principal volatile fission-product chlorides are Zr, Nb, Kr, and I; partially (<10%) volatile chlorides are Sb, Te, Mo, and Tc; nonvolatile chlorides are Ce, Cs, Sr, and Ru, The fluorides of Sb, Mo, Tc, Np, Nb, and Te are highly volatile but those of Ce, Cs, Sr, Zr, and Ru are nonvolatile. Iodine and krypton volatilized completely during the hydrochlorination step, and the iodine was removed completely from the process off-gas by a caustic scrubber. Tellurium was removed completely from the process off-gas with activated alumina.
