The Fukushima plant, which suffered a nuclear accident in 2011, has been found to be leaking contaminated water into the sea following heavy rainfall in the region caused by typhoon Etau, a spokesperson of Fukushima's operator confirmed to EFE Thursday.

Tokyo Electric Power, TEPCO, the plant's operator, is currently analyzing the magnitude of the accident, but said that the water leaked into the Pacific Ocean was not highly affected by radiation and did not pose a risk to the environment, the source added.

The leaks have been caused in the embankments around the tanks where highly radioactive water is stored after they are used to cool the reactors, and could have been caused by heavy rainfall which led to the accumulation of excessive amount of water the pipelines of the installation.

The arrival of typhoon Etau Tuesday has provoked torrential rains in several parts of Japan, with many of them registering record amounts of rainfall.

This is the seventh instance of similar leaks detected at Fukushima since April, when the plant employed a new pump system in its drainage channels to avoid radiation-contaminated water from emptying out into the sea in front of the plant.

TEPCO has proceeded to revise the embankments and drainage channels in the plant to check such leaks and prevent their recurrence in the future, the spokesperson said.

The Fukushima plant was badly damaged by a tsunami and an earthquake in March 2011, an accident considered the worst ever since the one in Chernobyl, in Ukraine, in 1986.
