Abstract
1,102,137. Fuel elements. HITACHI Ltd. 23 May, 1966 [24 May, 1965; 11 June, 1965], No. 22964/66. Heading G6C. A fuel element for a nuclear superheat reactor comprises fuel material and a process tube surrounding and spaced from the fuel material to provide a coolant passage, the process tube being made at least in part from a fertile material and/or a burnable poison whose fissile material content is lower than that of the fuel material, the process tube providing thermal insulation between water vapour coolant passing through the passage and a moderator. The fertile material may be depleted uranium oxide or natural uranium oxide or their mixtures, while the burnable poison may be boron carbide, europium or dysprosium. The addition of a very small amount of burnable poison to the process tube is sufficient to compensate for the fuel burn-up, whereas the addition of fertile material is never fully sufficient for this purpose. However, process tubes containing fertile material in producing fissile material are highly useful from the viewpoint of neutron economy.
