原子核乾板による浜岡２号機格納容器下部の観測（その２）
概要
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, observations using nuclear emulsion were conducted for the purpose of observing the lower part of the pressure vessel. This report gives an overview of the observations.
