内容記述 |
Radiation dose rates around liquid Li loops in International Fusion Materials Irradiation Facility (IFMIF)-like fusion neutron sources, such as A-FNS, increase because of the radionuclides produced by high-energy deuterons and neutrons. This study assesses radiation dose rates around the pipe, heat exchanger (HX), and electromagnetic pump (EMP) of a liquid Li loop using the Monte Carlo code MCNP6.2 and the photon data library mcplib84 to advance the development of maintenance strategies. The radiation sources include not only major nuclides (tritium and Be-7) reported in previous studies but also other radionuclides that have not been well investigated thus far. The calculation results suggest that hands-on maintenance of Li pipes can be performed after the Li drain. However, accesses HX and EMP are limited because of nuclides such as Y-88, which are produced from impurities in liquid Li, even when Be-7 is trapped in Cold Trap. |
