Abstract
Fission product activity levels have been measured using a transportab le gamma ray spectroscopy system at four SLOWPOKE-2 facilities. Throug h an analysis of the concentrations of these radionuclides in samples of the reactor coolant and gas headspace, the rate of release from the fuel has been determined by a Savitzky-Golay method and also by a non -linear least squares method. The release rate calculation has been va lidated against the mainframe code SUMRT. By examining the release rat es, the source of the short-lived fission products is determined to be direct recoil from exposed uranium-bearing surfaces.
