» Radioactivity levels exceeding in groundwater to release to ocean

Radioactivity levels exceeding standards to release groundwater into the ocean were discovered in a pump well at Fukushima No. 1 nuclear power plant.

TEPCO said 1,600 becquerels per liter of tritium were detected in one of 12 wells dug on the facility’s grounds to lift uncontaminated underground water before it can reach reactor buildings and become contaminated. The level tops the utility’s self-imposed standards of 1,500 becquerels per liter.

TEPCO said it has suspended pumping operations and that it intends to decide whether to resume operations after conducting an investigation into the groundwater on April 18.

The utility currently plans to divert groundwater from reactor buildings by pumping and storing it before it reaches the crippled reactors and then releasing it into the ocean.
