Equipment for the Detection of Residual Fuel in Leached Hulls by Neutrons Counting

Equipment has been developped for detecting small amount of fissile materials remaining in hulls, after irradiated fuel dissolving operation. The equipment described in this paper is running in French fuel processing plant AT-1 located at La Hague (France). The method consists in : - First, leached-...

Description
Summary:Equipment has been developped for detecting small amount of fissile materials remaining in hulls, after irradiated fuel dissolving operation. The equipment described in this paper is running in French fuel processing plant AT-1 located at La Hague (France). The method consists in : - First, leached-hulls irradiation by neutron generator. - Secondly, delayed-neutron counting techniques. It makes possible to monitor one basket full of leached-hull pieces in 30 minutes and to detect an amount of 20 milligrammes uranium 235 equivalent with 100 % accuracy.
