Description

Argentina has two Pressurised Heavy Water Reactors (PHWR) in operation at the present time: one is Atucha-1 and the second Embalse. Both are natural uranium fuelled. The use of slightly enriched uranium (SEU) in PHWR is an effective way to increase the fuel discharge burnup. The main benefits from the use of SEU cores are the following: Fuel cycle costs decrease; Uranium resources savings; Spent fuel volume decreases. Other advantages of core enrichment are described in the report. In order to test the overall performance under irradiation of SEU fuel, a first series of twelve Atucha-1 FA prototypes (0.85% U-235) was fabricated by Argentine domestic supplier. Work is carried out in Argentina in order to confirm the advantages and feasibility of PHWR fuel burnup extension programme. (author). 16 tabs
