technical field [0001] The invention relates to the technical field of multi-type neutron energy spectrum control, in particular to a multi-type neutron energy spectrum control target device. Background technique [0002] Advanced nuclear energy systems have the characteristics of hard neutron spectrum and strong anisotropy. Traditional fission reactors cannot provide the complex neutron spectrum required for key technology research and development. In the fusion neutron source-driven subcritical hybrid reactor energy system, the deuterium beam generated by the high-current deuterium-tritium fusion neutron generator bombards the solid target to generate a high-flux deuterium-tritium fusion neutron beam, and then uses the fusion neutrons to bombard the neutral target. Subcritical cladding of submultiplier materials, optimized by neutron multiplication and energy spectrum.

AI Technical Summary

Problems solved by technology

[0004] In the traditional technology, the traditional fusion neutron source target system works in an open external environment, and the target replacement operation is relatively easy, but it cannot be applied to the narrow and high temperature space conditions of the reactor core

In the fusion neutron source-driven subcritical hybrid reactor clean energy system, the target system of the neutron source works in the core of the subcritical reactor, the external space is small, and the surrounding core temperature is very high, so it is impossible to directly replace the target, and the target system is dismantled The workload of target replacement is too large, resulting in high labor intensity and low efficiency of target replacement
