Abstract
Section titled āAbstractāNuclear power plants regularly generate spent fuel that must be stored on the decade timescale. Often this is done in dry nuclear waste storage casks. Long-term monitoring would provide data that improves the safe maintenance of stored spent fuel. This requires measuring the conditions within waste casks using a self-contained sensor system. Radiation Monitoring Devices, Inc. is developing a system that detects damaged fuel rod cladding by sensing and quantifying the amount of 85Kr present using a diamond sensor. A potential means for power and data transfer through the cask wall uses an ultrasonic transmission method. The work described here advances the prototype toward inclusion in a specific model fuel cask, the NUHOMSĀ® 32 PTH1 manufactured by Orano (formally, Areva Transnuclear, Inc.). The results include extensive radiological modeling studies, an estimation of the leaked activity due to 85Kr after a cladding breach (~ 10 <sup xmlns:mml=āhttp://www.w3.org/1998/Math/MathMLā xmlns:xlink=āhttp://www.w3.org/1999/xlinkā>13</sup> Bq) derived from a literature review, a design for a prototype, and the characterization of a diamond detector at room temperature and in the presence of 85Kr.
