Why the plant intermittently emits steam; how groundwater seeps into its basement; whether fixes to the cooling system will hold; how nearby groundwater is contaminated by radioactive matter; how toxic water ends up in the sea and how to contain water that could overwhelm the facility’s storage tanks.

What is clear, say critics, is that Tokyo Electric Power Co is keeping a nervous Japanese public in the dark about what it does know.

The inability of the utility, known as Tepco, to get to grips with the situation raises questions over whether it can successfully decommission the Fukushima Daiichi plant, say industry experts and analysts.

“They let people know about the good things and hide the bad things. This culture of cover up hasn’t changed since the disaster,” said Atsushi Kasai, a former researcher at the Japan Atomic Energy Research Institute.

Tepco’s handling of the clean-up has complicated Japan’s efforts to restart its 50 nuclear power plants, almost all of which have been idled since the disaster over local community concerns about safety……

Tepco’s improvised efforts to stop radioactive water leaking into the sea include sinking an 800-meter-long steel barrier along the coastline, injecting the ground with solidifying chemicals and possibly even freezing the ground with technology used in subway-tunnel construction.

Industry experts are not impressed.

“You can’t do temporary fixes in nuclear power,” said Goto. “They say everything’s fine until bad data comes out.”
