Jan 22, 2020· Coroma is a robotic system development and integration project to automate a variety of manufacturing tasks. Most of these tasks are secondary finishing operations (e.g. grinding, sanding, deburring, etc.) which are typically carried out manually on welded components such as nuclear fuel racks and tube structures.

NRC: United Nuclear Corporation

The rate at which spent nuclear fuels release their radionuclide content upon water contact is a central issue to the safety assessment of spent nuclear fuel repositories. The majority of the radionuclides in spent nuclear fuels are distributed within the UO 2 matrix of the fuel and their release will be governed by the matrix dissolution .

Nuclear fuel cycle' Extractingg uranium from its ores

The pellets' surface areas are then ground and finished to precise dimensions to ready them for insertion into fuel assemblies. UO 2 removed during the grinding process is recycled back through the pelleting circuit. Meticulous attention to detail goes into nuclear fuel fabrication.

G. Rossiter, in Nuclear Fuel Cycle Science and Engineering, 2012. 14.2.4 Fuel grain growth (or restructuring) Ceramic fuel pellets consist of fuel grains with a range of grain sizes. The initial grain size distribution is determined by the manufacturing process and sintering conditions.

Nuclear fuel cycle - Wikipedia

The nuclear fuel cycle, also called nuclear fuel chain, is the progression of nuclear fuel through a series of differing stages. It consists of steps in the front end, which are the preparation of the fuel, steps in the service period in which the fuel is used during reactor operation, and steps in the back end, which are necessary to safely manage, contain, and either reprocess or dispose of ...
