Plan and progress of the fusion neutron sources development at KAERI for fusion and fission applications

摘要

In accordance with the national fusion energy program of Korea, Korea Atomic Energy Research Institute (KAERI) has established a road map for the development of a volumetric fusion neutron source (V-FNS) and begun development of a compact fusion neutron source (C-FNS) for fusion, fission, and industrial applications. Regarding the C-FNS development, KAERI has developed a radio frequency (RF) ion source inclusive of an RF driver and generator, and has designed, fabricated, and tested a target at the "Korea heat load test facility with an electron beam (KoHLT-EB)" prior to assembly with an ion source for investigating the integrity of the target under a high heat flux condition. Test conditions such as heat flux, coolant flow rate, and pressure were prepared using a preliminary analysis and later compared against test results. From the comparison, the design of the target was optimized and its thermal integrity confirmed. Thus far, KAERI has been successful in its development of a C-FNS and has begun preparations for on-site C-FNS and V-FNS designs.
