Fukushima Unit 1 Upcoming Inspection; What You Need To Know



TEPCO and the various entities tasked with dealing with the disaster clean up at Fukushima Daiichi have announced details of the upcoming inspection inside unit 1.

When: Summer 2019
Where: Inside containment of unit 1.

The inspection efforts are typically described as being done by robots. Most of the more recent inspections are actually done with ROVs (Remote Operated Vehicle). An ROV has a tether cable used to operate and power the mobile unit. This increases the complexity of the work but gives more reliability to the control of the unit.

A fleet of five robots will be used to complete the work. Each of these ROV units is roughly the weight of a large dog, making them the largest inspection “robots” used inside containment to date. A smaller ROV will be used to visually monitor the other units as they conduct their work. A set of eight rings will first be installed inside containment. These act as route guides for the ROV units and keep the tether cable from becoming entangled in structures inside containment. Then each ROV unit will be used separately to do a specific task related to the planned inspections.
