Description

The Mirion WM2200 Segmented Assay System is designed to perform accurate quantitative assays on gamma emitting nuclides found in fission product, activation product, and Transuranic (TRU) waste. With the optional ASTM algorithms it is also designed for use in safeguards applications. The system provides very accurate assays through the use of a collimated high purity germanium detector. The container is divided into a number of vertical segments and the activity is quantified in each vertical segment using matrix correction techniques which calculate the average matrix density for each segment.

The standard system configuration is designed to assay 200 liter (55-gallon) drums and support weights up to 900 kg (2000 lb). Optional configurations have been provided for larger or heavier containers from 320 L (85 gal) drums to HICs.

The standard system is designed to assay radionuclides such as ⁶⁰Co or ¹³⁷Cs with drum activities ranging from approximately 100 nCi up to approximately 20 mCi. For transuranic waste the system is optimized for assaying drums containing 0.1 gram up to 1000 grams of ²³⁵U or ²³⁹Pu. Detector size and collimation can be used to modify the dynamic range of the system.
