What is Design and analysis of the radiation shield and safety system for HT-7U tokamak about?

The design of the radiation shield and safety system for the HT-7U fusion experimental device is presented in this contribution. An inner shield and an outer shield are considered in the shield design. Calculations and analyses have been done using 3D MCNP/4C models for the neutron spectrum and with the inventory code FISPACT for activation calculation in order to estimate the dose rate to workers after one pulse operation of the device. In addition, a computer system for radiation protection and control based on Controller Area Network has been developed in order to protect staff and publics from the radiation of neutrons and g during and after the operation of the HT-7U device. The safety system has the advantages of multi-master protocol, real-time capability, error correction, long communication distance and high noise immunity etc.
