Abstract
An elongate fuel element sub-assembly for use in a liquid metal cooled fast breeder nuclear reactor is adapted at a base end region for plugging into core support means and at the upper free end there is inertia damping means to prevent excessive vibration.
Claims3
A fuel element sub-assembly for a liquid metal cooled fast breeder nuclear reactor, the fuel element sub-assembly being elongate and having a base end region adapted for plugging into fuel assembly support means, and inertia damping means disposed at an upper end region of the sub-assembly, the inertia damping means comprising:
- a lower sleeve rigidly attached to the fuel element sub-assembly;
- a tubular spine rigidly and co-axially attached to the lower sleeve;
- an upper sleeve mounted co-axially on the tubular spine with a radial spacing therebetween and resiliently coupled to the lower sleeve, the upper sleeve having coolant flow ducts extending therethrough to the radial clearance.
