Design and analysis of mock-up of CFETR water cooled ceramic blanket for neutronics experiment

The neutronics experiment of the WCCB blanket is to validate the neutron transport codes and nuclear data libraries. A scaled down mock-up of the WCCB blanket should be designed considering constraints of economic costs and experimental conditions before the neutronics experiment.

In this work, the mockup was designed keeping neutronics and geometric characteristics of the original equatorial outboard blanket module of CFETR. The radial arrangement of the mock-up was designed firstly, including tungsten armor, first wall, breeding zone 1, beryllium layer 1, cooling plate 1, breeding zone 2, beryllium layer 2, cooling plate 2. Then the toroidal and poloidal dimensions of mock-up were optimized.
