Apparatus for Diffusion Coefficient Determination Using Tritium
For the construction of a radioactive waste storage or disposal facility, it is necessary to construct impervious barriers. Apart from advection, the main way of possible penetration of radionuclides from waste is diffusion. Since tritium is, physically, the smallest radionuclide with the greatest possibility of passing through barriers, the diffusion coefficient determined by it gives the greatest potential, and the probability of seepage of other radionuclides can only be less. The device was made on a 3D printer, and bentonite was used as a test material. It is assumed that the test will continue with other materials used in repositories: concrete, clay, etc. The device is used for scientific and research purposes, but also in teaching, if instead of tritium another non-radioactive tracer will be used, for example salt in case of testing the diffusion coefficient at liners for landfills for municipal waste. The special feature of the device is portability, extremely high quality and low price, easy installation of the sealing material sample as well as fluid sampling.
