摘要

The Savannah River Site(SRS)has several inventories of depleted,natural,and low enriched uranium(DU/NU/LEU)that require final disposition.Fiscal Year 2003(FY03)saw the beginning of disposition actions for these inventories.This poster shows these inventories from storage,through preparation for shipping,through packaging and transportation(P&T)steps,and finally disposal of each material stream. rnIn FY03,SRS completed a pilot project to dispose of 3,270 drums of depleted uranium oxide (DUO)between May and July 2003.The shipping method was 110-ton mill gondola rail cars with a polypropylene-coated fabric liner(“wrapper”)as the DOT“strong,tight”package.These rail cars were shipped to Envirocare of Utah for final disposition of the DUO as low level waste. rnThe disposition project for the remaining inventory began in February 2004.Since there were issues with the wrapper during the pilot,shipping of the remaining drums will be accomplished using boxcars for drums that are already overpacked into 85-gallon drums or gondola cars with hard tops for the remaining 55-gallon drums. rnThe SRS inventories of DU and NU metal were also dispositioned in FY03.These inventories were shipped by commercial tractor/trailer truck to Envirocare of Utah. rnMany universities have inventories of NU metal that are on loan from DOE.Through September 2003,SR shipped the material from five universities directly to the Nevada Test Site for disposal.The material was never physically returned to SRS thus saving a shipping step.These five universities provided the pilot to develop this program that is planned to continue until the material from all of the universities is dispositioned. rnDepleted uranyl nitrate(DUN)is being shipped as a radioactive acid solution to a treatment vendor and is being treated before disposal.The low enriched uranium oxide(LEUO)seems to be the stream with the least P&T issues but has yet to be shipped.Plans are to ship this material by commercial tractor/trailer truck to NTS for disposal.
