Fukushima Daiichi Nuclear Power Station Unit 1 Containment Vessel Investigation Delayed TEPCO January 31 8:41
In an investigation into the containment vessel planned for Fukushima Daiichi Nuclear Power Station Unit 1, which caused a meltdown, TEPCO announced that it had become difficult to start by March. The start time will be shown again.
For Fukushima Daiichi Nuclear Power Plant, TEPCO planned to start the operation by March, using a robot to inspect the inside of the containment vessel containing the reactor.
However, while drilling holes for investigation into the containment door using high-pressure water, a problem occurred in which radioactive material accumulated inside was soared and the concentration increased.
After that, I reviewed the work procedure, but I haven't made any holes yet.
For this reason, TEPCO announced on Thursday that it would be difficult to start an investigation by March. The timing of the start will be shown again in the future.
In the investigation of the inside of the containment vessel using a robot, Units 2 and 3 have successfully confirmed deposits that are thought to contain melted nuclear fuel.
