[1L02] Basic design of high-performance moderator vessel for JRR-3 cold neutron source

(2)Evaluation of moderator vessel by structural analysis

Keywords:JRR-3, Cold neutron source, Moderator Cell, Structural analysis

The vessel shape was changed from the conceptual design to take manufacturability into consideration. The inner surface of the vessel is filleted, and the flat section is reinforced and tapered. To verify its validity, check for plastic deformation at maximum pressure.
