Coated Particle Fuel for the Dragon Reactor Experiment. Dragon Project Report

A brief description of the core of the Dragon Reactor is presented with emphasis on the major objectives concerning fuel element development Reference is made to the proposed specification for the initial charge in describing the methods chosen for production of the coated particle fuel assemblies. An experimental fluidised bed employed for all coating studies is described and the development of the prototype production apparatus traced through its various stages. Methods used for making composite coatings of pyrolytic carbon/graphite and silicon carbide are discussed and initial results of the evaluation studies presented. (author)
