摘要

The ITREC plant (Treatment and Remaking Fuel Elements Plant), near the Trisaia locality (south Italy), wasrnbuilt in the frame of a collaboration between CNEN (Nuclear Energy National Committee) and USAECrn(United States Atomic Energy Commission) to study the feasibility of U-Th fuel cycle. Some reprocessingrncampaigns have been carried out since 1975, mainly using fuel elements coming from the Elk River Powerrnplant (USA).rnThe about 2,40 cubic meter of high level liquid wastes arising from these nuclear tests was stored in the plantrnsite.rnA chemical process based on the cementation of liquid wastes by addition to dry cement in a drum wasrnstudied and applied in order to immobilize them in an encapsulated and shielded solid form. It was performedrnin the SIRTE-MOWA plant (Unit System to prepare, to transfer and to treat radioactive liquid waste inrnMobile Waste). The above mentioned 2,40 cubic meter of high level liquid waste, batch by batch, has beenrnmixed with low level liquid waste to get the desired standard concentration of Cs-137 (7,50 E-02 Ci/l (2,77rnGBq/l). The production is constituted from a number of 213 cemented drums with a radioactive content ofrnabout 15 Ci (555 GBq) for every drum.rnThe final product is suitable to be stored in the future National Storage Site.
