Development and evaluation of a neutron-photon shield for transuranic waste containers.

PDF Version Also Available for Download.

Description

The Los Alamos National Laboratory (LANL) Operational Health Physics Group in conjunction with the Nuclear Materials Technology Division Waste Management Group has developed a wraparound shield for use with 55-gallon (0.208 cubic meter) drums containing transuranic (TRU) waste. The shield or 'drum cover' as it is called, is innovative in its ability to shield both neutron and gamma photons associated with TRU waste. The shielding materials are comprised of a 0.275-inch (7mm) thick sheet of borated polyurethane for neutrons, and two sheets of composite lead vinyl fabric (equivalent to 0.35 mm of lead) for shielding photons. The drum covers have ... continued below

The shielding materials are comprised of a 0.275-inch (7mm) thick sheet of borated polyurethane for neutrons, and two sheets of composite lead vinyl fabric (equivalent to 0.35 mm of lead) for shielding photons. The drum covers have proven their relative effectiveness. Shielding tests have shown that the drum covers are highly effective in attenuating photons and are somewhat effective for shielding neutrons. Total (neutron and photon) radiation reduction for actual TRU drurns has been as high as 87%.
