Abstract
Provided herein is a neutron moderation module and a thermal-neutron nuclear micro-reactor.
Claims19
A neutron moderation module comprising:
- a metal hydride core;
- and
- a shell surrounding the core, the shell comprising:
- at least one H2 permeation barrier layer;
- at least one transition metal layer;
- at least one diffusion barrier layer;
- and
- at least one ceramic matrix composite layer,
- wherein:
- the at least one H2 permeation barrier layer is disposed between the at least one transition metal layer and the core,
- the at least one H2 permeation barrier layer and the at least one diffusion barrier layer are separate separated by the at least one transition metal layer, and
- the at least one diffusion barrier layer is disposed between the at least one transition metal layer and the at least one ceramic matrix composite layer.
