Abstract

The radiation intensity around the melted reactors and melted nuclear fuel at the Fukushima Daiichi nuclear power plant is exceedingly high: in the worst case, it is reportedly as high 1000 Sv/h. Therefore, decommissioning the melted reactors and extracting the melted nuclear fuel require radiation-hardened robots. This paper presents a radiation-hardened parallel-operation-oriented optically reconfigurable gate array (ORGA) consisting of a gate array VLSI, a holographic memory, and a laser array for incorporation into such radiation-hardened robots. Using a Co60 gamma radiation source, the radiation tolerance of this radiation-hardened parallel-operation-oriented ORGA VLSI has been confirmed experimentally as 1.15 Grad, which is about 1,150 times greater tolerance than those of commercially available radiation-hardened VLSIs.
