Fukushima water decontamination system down again

Mar 25, 2014
Welded tanks are shown above ground at the Fukushima Daiichi nuclear power plant on March 10, 2014, nearly three years after the plant was paralyzed by the March 11 earthquake and tsunami in 2011

The operator of Japan's crippled Fukushima nuclear plant said Tuesday it had shut down a key decontamination system used to clean radiation-tainted water, just hours after it came back online.

Tokyo Electric Power (TEPCO) switched off its Advanced Liquid Processing System (ALPS) after workers discovered leaks "seeping" from a tank late Monday.

About eight litres (2.1 gallons) of tainted is believed to have leaked out, a company spokesman said. He added there was no immediate safety risk as the water had been recovered.

The suspension came just six hours after the embattled operator switched back on two of three lines in the system, which cleans radiation-tainted water used to cool the reactors damaged by Japan's devastating 2011 quake-tsunami disaster.

The whole system had been shut down last Wednesday after TEPCO discovered a defect. The firm has repeatedly switched the system off over a series of glitches since trial operations began a year ago.

TEPCO is struggling to handle a huge—and growing—volume of contaminated water at Fukushima following the quake-tsunami, which sparked the worst atomic crisis in a generation as well as sweeping away some 18,000 victims.

Giant waves crashed into the plant, sparking reactor meltdowns and explosions. Cleaning up the shattered site is expected to take decades.

There are about 436,000 cubic metres of stored at the site in about 1,200 purpose-built tanks.

Many experts say that at some point the water will have to be released into the sea after being scrubbed of the most harmful contaminants.

They say it will pose a negligible risk to marine life or people, but local fishermen and neighbouring countries are fiercely opposed.

As most of your world-weary readers suspected, the radioactive water will be released either in an accident---supported by inexperienced workers---or by necessity. Many are not aware that there are designated sites for nuclear disposal that exist in the world's oceans. The United Nations has sanctioned these sites for the Asian countries that have insufficient land for disposal.
Sadly, this portends further releases as the accumulated spent fuel rods continue to need cooling. As 75 years ago, the proposed solution is still the futile hope for fusion. Why? Because there is no other solution for this radioactive toxin.
Fusion seems to be forbidden here on Earth as the sun itself has a slight imbalance between hemispheres which may the cause of the imbalance on the quantum level that disrupts the magnetic pressure leading to a controlled implosion.
