Spallation neutron source provides thermal and cold neutrons for materials researches. Those neutrons are obtained by slowing down the neutrons generated in a neutron production target by injecting high energy protons in surrounding reflector and moderators. This article introduces basic characteristics of the neutron production target at first, and then explains the characteristics of moderator, especially the design to generate high intensity and high quality neutron pulses with narrow width in the moderators used in the 1-MW spallation neutron source at J-PARC. Furthermore, the design procedure of the spallation neutron source is described.

Considering the geometrical characteristics of tokamak reactors with low aspect ratio, a basic neutronics strategy was derived to construct the inboard structure mainly for neutron shielding and produce enough tritium in the outboard blanket. The designs for optimal inboard shield were surveyed and necessary thickness was estimated to make the neutron flux low enough on the super-conducting magnet. In addition, the outer blanket designs were studied to attain the tritium breeding ratio (TBR) large enough for a self-sustaining fusion reactor on the basis of the advanced fusion reactor materials.

The sixth replacement of beryllium frame has been accomplished for the west and north frame, while the old east frame of fifth generation is preserved for use. JMTR achieved its first criticality in 1968 and has been in operation until today, with an integrated thermal output of 141.454.5 MWd. During that period replacement was carried out 4 times for all the frames, east, west and north. This time, differently from the previous replacement, west and north frames only were manufactured and installed, when the old east frame was left for continuous use, based on the past experience. Such a strategy contributed to reduction of budget and the waste associated.
