aggregate minerals amorphization Ion irradiation radiation-induced volume expansion
Long-term radiation exposure can cause damage of concrete structures due to the volume expansion of the aggregate minerals. In this study, granite, sandstone, and tuff were irradiated with 2.8 MeV Fe2+ at room temperature to different level of ion fluences. Step height measurement was conducted to quantify the volume change. It was found that the swelling of all minerals saturated at around 300 nm. Tuff, which contains almost all silica, exhibited the fastest swelling, among others.

Attenuation Method Muon Radiography Nuclear Emulsion PCV RPV
Muon radiography is one of the remote sensing technologies, and it has been used at Fukushima Daiichi NPP to understand the status of the fuel inside the reactor. Nuclear Emulsion is one of the detectors used for muon radiography. Its features are light weight, compact size, no power supply required, high position resolution, and suitable for installation in a limited space.
So far, at the Hamaoka NPP, from the floor on the second underground level and the sub-drain in the building-outdoor part, observation...

Concrete FEM Irradiation LWR Neutron RBSM
A new research program of irradiation effects on LWR concrete member has been started since 2017. The previous research results indicate the reference level of neutron irradiation degradation on concrete should be set at 1 x 1019 n/cm2 which is one order of magnitude lower than the conventional reference level used in Japan. Several issues remain after the previous research and the objectives for clarifying the issues are set in the new project which is scheduled for five and half years. And international c...
