Description

The paper describes experimental studies on the isotopic composition of irradiated WWER-440 reactors fuel carried out for fresh fuel enriched to 3.6% and burnup of 20 to 40 MWd/t U. The authors have obtained experimental data on the isotopic correlation ratio for plutonium isotopes depending on burnup, 235U isotopic ratio, isotopic plutonium ratio, and cesium ratio on burnup. The discrepancy between experimental and calculated values was usually not more than 5 to 7%. The experimental data on isotopic correlations could be useful for the purposes of IAEA safeguards.
