| Abstract: | In nuclear safeguards field, calorimeter is one of the most accurate and convenient nondestructive instruments for nuclear material accountancy. A calorimeter designed to measure plutonium in storage containers with thermal powers ranging from 0.1 to 15 W was used to measure the mass of 238Pu in three samples. Measured results show that the relative deviation between the measured 238Pu mass and standard reference 238Pu mass in samples of 238Pu is -1.7%. |
