Abstract

Thermal/hydrological modeling of the Radioactive Scrap and Waste Facility(RSWF) has been completed with the TOUGH2 (Transport of UnsaturatedGroundwater and Heat) Code.[1] The RSWF will be utilized as an interimstorage facility for ceramic and metallic waste forms developed from theelectrometallurgical treatment of spent nuclear fuel. The RSWF is an arrayof 1,350 carbon steel liners located at grade near Argonne NationalLaboratory-West on the Idaho National Engineering Laboratory (INEL).

The primary driving force for this modeling research was to assess thermalcapacity limits for RSWF liners so that heat generating materials can besafely stored. Maximum wasteform temperatures will be governed by both theamount of heat the system can dissipate and the orientation andcharacteristics of the wasteform. The focus of this report is on the amountof heat the interim storage system can safely dissipate. The effect of thetemporal variation of soil moisture on the performance of the RSWF isassessed. The facility was analyzed to determine the maximum allowablethermal loading of the RSWF liners.
