1. Electricite de France, Clamart (France)

Technical and economical pressurized water reactor (PWR) performances are strongly influenced by fuel management, e.g., fuel utilization and core design. Because of the large number of standardized French PWR units, this question is of considerable importance for Electricite de France (EdF). At present, EdF operates two standardized types of PWR: thirty-four 900-MW and twenty 1300-MW PWRS. Economic optimization will lead to global management of the nuclear power plants in the coming years through three main types of fuel management: four-batch 3.7% UO[sub 2] management and plutonium recycling management for the 900-MW PWRs and extended cycle management for the 1300-MW PWRS. The best optimization is made on each reactor by computing a loading pattern that flattens the power map to ensure a certain flexibility of operation (early shutdown, stretch-out).
