DESIGN AND ANALYSIS OF A MODERATOR CELL STRUCTURE FOR CARR CNS
A new moderator cell structure based on the single-phase thermo-siphon loop is proposed for the Cold Neutron Source (CNS) of China Advanced Research Reactor (CARR). Different from previous single-phase moderator cells, the design scheme of a crescent-shape hydrogen layer together with a helium cooling jacket is adopted in this paper. Theoretical analyses on cold neutron gain factor, heat transfer performance and structural strength of the moderator cell are carried out aiming at optimizing the preliminary design scheme. Results show that the modified moderator cell has high cold neutron gain factor, good heat transfer capacity and low stress ，which could meet the function requirements of the CNS of CARR.
