AN INTEGRAL EXPERIMENT RELATING TO CALIBRATION AND INTERPRETATION OF PLUTONIUM SOLID WASTE MEASUREMENTS AT DOUNREAY NUCLEAR POWER DEVELOPMENT ESTABLISHMENT
This report represents collaborative work carried out by UKAEA Dounreay, Joint Research Centre Ispra and Lyon University France which relates to the characterisation and sampling of two selected solid waste streams in the PFR fuel reprocessing operation at DNPDE. The ultimate check on any non-destructive analysis measurement of plutonium in solid wastes is a comparison of the measured value to the value obtained by destructive analysis. A prerequisite to destructive analysis is thorough characterisation of the waste streams in terms of plutonium content, matrix and density. This paper (Part 3 in the series) gives details of the sampling procedures, historical data and destructive analysis techniques applied to high alpha - beta - gamma (leached hulls) and high alpha low gamma waste streams arising from PFR fuel reprocessing. The work was carried out after two PFR fuel reprocessing campaigns had been completed thus providing adequate statistical data. The levels of plutonium found in these streams was much lower than anticipated; this required some modification of the destructive analysis approach. These procedures must be repeated at intervals in order to establish a meaningful statistical pattern.
