Abstract

A Single Fluid Reactor with an inner zone that includes a solid neutron moderator, which can have through holes defined therein. This solid neutron moderator can have a relatively small diameter, which can range, in some embodiments, from less than one meter to about 1.5 meter. The solid neutron moderator effectively creates an inner zone with a neutron profile that is far more thermalized than if the solid neutron moderator were absent. The surrounding layer of salt surrounding this inner zone has a much harder neutron spectrum.

IPC Classes  ?

• G21C 1/22 - Heterogeneous reactors, i.e. in which fuel and moderator are separated using liquid or gaseous fuel
• G21C 1/03 - Fast fission reactors, i.e. reactors not using a moderator cooled by a coolant not essentially pressurised, e.g. pool-type reactors
• G21C 5/12 - Moderator or core structure; Selection of materials for use as moderator characterised by composition, e.g. the moderator containing additional substances which ensure improved heat resistance of the moderator
• G21C 5/14 - Moderator or core structure; Selection of materials for use as moderator characterised by shape
• G21C 5/18 - Moderator or core structure; Selection of materials for use as moderator characterised by the provision of more than one active zone
• G21C 1/02 - Fast fission reactors, i.e. reactors not using a moderator
• G21C 3/54 - Fused salt, oxide, or hydroxide compositions

Abstract

A molten salt breeder reactor that has a fuel conduit surrounded by a fertile blanket. The fuel salt conduit has an elongated core section. The geometry of the fuel conduit is such that sub-critical conditions exist near the input and output of the fuel salt conduit and the fertile blanket surrounds the input and the output of the fuel salt conduit, thereby minimizing losses.
