Japan's Fukushima Nuclear Plant suffered three catastrophic meltdowns after the notorious earthquake and tsunami of 2011.

Since then, authorities have battled to contain the radiation within the plant, with it continuing to escape through the groundwater.

Every day, tons of this liquid pours through a building housing four of the failed reactors, picking up radiation as it goes.

And now the latest attempt to seal off the disaster zone, a wall of frozen earth around it, appears to have failed.

A panel of experts with the Nuclear Regulation Authority said readings from the ocean-side of the wall continued to remain high.

While radioactivity is still being found on the other side of the Pacific, off America's west coast, according to US media reports.

Now, with the 34.5billion yen (£263m) scheme in peril, Tokyo Electric Power Company (TEPCO) has been told to find a new solution.

Yoshinori Kitsutaka, from the regulation authority, told Japan's Asahi Shimbun newspaper: “The plan to block groundwater with a frozen wall of earth is failing."

While TEPCO declared its wall was 99% effective and proposed injecting concrete into the 1% that is still not fully frozen.

However, Mr Kitsutaka said: "They need to come up with another solution, even if they keep going forward with the plan."

TEPCO has been asked to calculate how much groundwater can be diverted if it is pumped before it reaches the wall.
