Abstract

The Collaborative Project (CP) FIRST-Nuclides ("Fast/Instant Release of Safety Relevant Radionuclides from Spent Nuclear Fuel") is aimed at providing new and comprehensive knowledge of the fast release of safety relevant radionuclides from used high burn-up light water reactors (LWR) UO2 fuel. The results cover the dissolution based instant release fraction (IRF) from PWR and BWR fuels with enrichments between 3.3 to 4.9 % 235U, burn-up between 50 and 70 GWd/tHM, power rates from 160 to 330 W/cm and fission gas releases (FGR) of 1 to 14 %. The experiments comprise clad and unclad pellets, segments of pellets, fragments and powders. The experiments were performed using the same bicarbonate groundwater composition.
