Developers and users of calorimetric assay instruments and measurements, together with interested persons from international and domestic inspectorates and nuclear facilities, have conducted a one week workshop on the calorimetric assay of plutonium and tritium. Basic technology topics included the specific powers of radionuclides, the different types of calorimeters available for power measurements and the chemical and non-destructive gamma-ray measurements of plutonium isotopic composition. Methods to reduce measurement times have been discussed and demonstrated. Instrumentation assembled for the workshop included a water bath calorimeter, dry transportable calorimeters built in the USA and dry transportable calorimeters built in England, along with gamma-ray systems for measuring plutonium isotopic composition and calculating plutonium effective specific power.
