The French National Radioactive Waste Management Agency (ANDRA) is currently undergoing development of radwaste package quality qualification and there was a need to sample a radioactive waste hull. The purpose of sampling was for radiological and chemical analyses to thus characterize the radioactive contents of the waste block and check the block’s homogeneity in conformance to French waste acceptance criteria and regulations. By sampling the block using TruPro® the number of representative samples collected was maximized whilst minimizing the total quantity of extracted material and also minimized the physical degradation of the package during sampling operations.
NMNTI can obtain samples from the waste block concrete subsurface materials and analyze for Cs-137, Co-60, Ag-110m, Sb-125 and Sb-124 gamma nuclides for these samples in close proximity to sampling operations. The waste block sampling work usually takes place in a large intervention cell to minimize risks to people and the environment. The sampling of the radioactive waste block ascertains the NMNTI ability to acquire dry samples from the waste package and ascertain the homogeneity of the waste block material with respect to Cs-137, Co-60, Ag-110m, Sb-125, Sb-124 and difficult to measure radionuclides of the waste package.
