Abstract

This invention relates to a nuclear reactor 10 which includes a hollow core vessel 12 and a modular filler member 20 positioned within the core vessel 12 such that a core cavity 22 is defined around the filler member 20. The filler member 20 is of layered structure comprising a plurality of interconnected layers 42 of blocks 40, each layer 42 comprising a plurality of laterally inter-engaged blocks 40. The invention extends to a method of constructing a central column 20 of a nuclear reactor 10.
