Conceptual Design of Passive Moderator System for Thorium-Based Advanced CANDU Reactor

A conceptual design which can meet the passive safety requirement is established in the study of the passive moderator system Thorium based Advanced CANDU Reactor (TACR). In this design, the moderator cooling system (MCS) and the passive moderator residual heat removal system (PMRHR) are combined together for the first time. The steady operation during normal work of the reactor is analyzed by CATHENA Mod3.5c/Rev1, which provides a base for the verification of the design reliability.
