 note = {Advanced Fusion Neutron Source (A-FNS) is an accelerator-driven (IFMIF-type) fusion neutron source to offer fast neutrons to study irradiation effects on fusion reactor materials, which is to be sited at Rokkasho, Japan. A-FNS should be designed so that radiation safety is assured for workers and the public with compliance of the Japanese radiation safety regulation, that was revised in 2017. The revision that should be accounted for the A-FNS conceptual and forthcoming engineering design is that “safety provisions should be made a priori for emergency situations.” We present safety requirements, safety functions and associated safety analysis of the A-FNS conceptual design. We have developed safety requirements for the A-FNS design, which are in compliance not only with the revised Japanese regulation but also to the international nuclear/radiation safety standards. Numerical project guidelines are presented, which satisfy the safety requirements for radiation safety of workers and the public. We have analyzed a “bounding accident case” of A-FNS at Rokkasho, in which all the amount of the major mobilizable radioactive materials, i.e. beryllium-7 in the target liquid lithium loop, are released to the environment. We performed a site-specific dose analysis using meteorological data observed at Rokkasho. The simulation result indicates that the early dose to the public (for a week) 200∼300 m away from the release point is 1∼2 orders of magnitude smaller than the IAEA guideline for emergent evacuation of the public, 100 mSv., 14th International Symposium on Fusion Nuclear Technology},
