FAST NEUTRON NUCLEAR REACTOR EQUIPPED WITH CORIUM RECUPERATOR

摘要

A lead bed (14) is disposed under a nuclear reactor core (3) so as to recover it in case of melting, with heat absorption, protection of the underlying structures and moderation of the criticality by spreading. better than traditional concrete recuperators. It can be placed between the main tank (1) and the safety tank (6), or below the safety tank, at the bottom of the tank well (2). It advantageously extends to an annular portion (13) of refractory material, which protects the surrounding structures. Application to fast neutron reactors.
