TY - JOUR AB - Investigation of nuclear criticality in powder systems is necessary for the assessment of industrial plant integrity and potential radiation impacts on worker and the public health. For nuclear fuel processing, to produce fuel pellets, MOX (UO2 + PuO2) and zinc stearate (lubricant) powders are homogenised in a stirred vessel. The coupled multi-fluids (multiphase and multi-component) and neutron-radiation transport FETCH model was extended to simulate reactivity feedback mechanisms and to assess safety and potential risks of criticality incursions in 2-3D systems. This work has strengthened links with the Japan Atomic Energy Agency (JAEA), led to consultancy work with Japanese National Labs and work with Tokyo University that led on to the Todai Forum and the core to core program with Japan.
