Housed within a customised shipping container, the UDASS deploys a battery of gamma assay techniques and provides the most accurate tool for waste drum assay and segregation at the ILW-PCM/TRU to LLW boundary. As well as below the VLLW and under the right circumstances, Out of Scope too.
The Performance of the UDASS has recently been demonstrated in a recategorisation campaign at the UK National Low Level Waste Repository (LLWR). The UDASS design has been optimised to fit within a shipping container, along with an operator office and observation point. The container has a self-contained electrical distribution network, complete with lighting and air-conditioning for operator comfort. This means the only service required is a single phase electrical supply.
