THERMAL NEUTRON REACTOR CORE AND METHOD FOR DESIGNING A THERMAL NEUTRON REACTOR CORE

摘要

A thermal neutron reactor core (1) comprises: a solid moderator (3) extending in a longitudinal direction; a fuel (2) in the moderator (3), parallel to the longitudinal direction of the moderator (3), the fuel (2) containing a fissile material; a cooling tube (6) parallel to the longitudinal direction of the moderator (3); and a plurality of types of consumable poisons contained in the fuel (2). The (moderator) may contain a metal hydride. In addition, the plurality of types of consumable poisons may include a consumable poison containing a certain concentration of a particular isotope of this consumable poison.
