Los Alamos National Laboratory (LANL) has been tasked to produce 120 kg of plutonium as highly purified PuO2 for the European Mixed Oxide (MOX) Lead Test Assembly managed by Duke, COGEMA, Stone & Webster (DCS). To meet stringent and challenging techn

Investigations of an advanced fuel form are currently under way. This new fuel form, referred to as evolutionary mixed oxide (EMOX), is a slight perturbation on standard mixed-oxide (MOX) fuel, and analyses show that it can be an effective plutonium

Aqueous processing is necessary for the removal of impurities from 238Pu dioxide (238PuO2) scrap due to unacceptable levels of 234U and other non-actinide impurities. 238PuO2 is used to supply the thermal energy in General Purpose Heat Sources (GPHS)

The use of ion exchange during the aqueous purification of 238Pu oxide results in low levels of uranium, thorium, and americium in the product oxide. Neutron emission rates are also reduced in the product oxide. Fluorine introduced during the dissolu

A glovebox facility is under construction at Los Alamos that will recover a significant quantity of the impure Pu-238 that exists in scrap and residues from past production operations. The general flowsheet consists of milling, acid dissolution, ion

This paper describes bench-scale efforts (5–7 grams of 238Pu) to optimize the ion exchange process for 234U separation with minimal 238Pu losses to the effluent and wash liquids. The bench-scale experiments also determine the methodology to be used
