Japan could release Fukushima radioactive water into environment

TOKYO, Dec 24, 2019 (BSS/AFP) – A Japanese government agency has proposed
releasing radioactive water from the stricken Fukushima nuclear plant into
the environment, as storage space runs out.

The plant suffered a meltdown about nine years ago after it was hit by an
earthquake-triggered tsunami. About a million tonnes of contaminated water
has built up since then and the tanks that hold it are almost full.

The government’s Agency for Natural Resources and Energy on Monday proposed
three ways to deal with the water — releasing it into the sea, into the air
using vaporisation or a combination of the two.

“There is no option (any longer) of simply storing the water for a long
period of time,” an agency official told AFP on Tuesday.

An extensive pumping and filtration system is in place at the plant, which
each day brings up tonnes of newly contaminated water and filters out almost
all radioactive elements.

The process leaves only tritium, which experts say is only harmful to
humans in very large doses.

No decision was taken at Monday’s meeting but “no members voiced opposition
to the view that a technically realistic way is discharging the water into
the sea or the air,” according to the agency official.

The panel has been discussing how to dispose of the liquid for years and no
deadline has been set for it to report to the government.

The radioactive water comes from several different sources, including water
used for cooling at the plant groundwater that seeps into the plant daily and
rainwater.

Properly filtered Fukushima water could be diluted with seawater and safely
released into the ocean without causing environmental problems, the
International Atomic Energy Agency argues.

Discharging it into the environment could trigger protests however — not
only from local fishermen and farmers but also from neighbouring countries.

The treated water is currently kept in a thousand huge tanks at the
Fukushima Daiichi site.

Plant operator TEPCO is building more tanks but all will be full by the
summer of 2022.
