The calorimetric assay of plutonium is an established and documented technique used extensively in DOE facilities for accountability measurements. Multilaboratory studies have quantified an average bias of <0.2% for the calorimetric assay of a wide range of plutonium bearing materials and plutonium isotopic compositions. This average bias can be reduced to <0.1% using new half-life values provided in independent studies by the U.S. Half-Life Evaluation Committee. An inspectors' verification program, utilizing calorimetric assay, has resulted in the increased use of calorimetric assay for calibration of plutonium nondestructive assay (NDA). The use of calorimetric assay as a standard reference methodology for improved plutonium NDA measurement control is recommended.
