When contaminated groundwater is leaking into the ocean, it is expected that authorities are informed. It may have been a previous issue of TEPCO before, but when their liquid glass project serving as a seawall failed to keep radioactive contaminated waters from reaching the ocean waters, then all the more should the Fukushima operators inform the Nuclear Regulation Authority. But no timely report reached the nuclear watchdogs.
The liquid glass was constructed with a length of 100 metres and a depth of 16 metres. TEPCO considered hardening the soil but the plan turned into naught reasoning that it was impossible. It was also found out that the increase of radioactive contaminated waters leaked out was up to 2.5 metres. With the unquestionable discovery, TEPCO admitted that the seawall did not serve its purpose. “We cannot deny that now [even after the shielding wall was constructed], the groundwater is leaking into the ocean,” TEPCO said.
The Nuclear Regulation Authority experts had gathered together on Monday, the day when TEPCO could’ve informed the agency regarding contaminated groundwater level near the seawall instead of two days later. During a regular meeting on Wednesday, NRA implied that the report came late and incomplete. NRA Chairman Shunichi Tanaka even charged that “TEPCO has no sense of crisis at all.”
