WATER WORLD
Water decontamination system in trouble at Japan's Fukushima
by Staff Writers
Tokyo (AFP) Dec 01, 2013


A trouble-prone system used to decontaminate radioactive water at Japan's crippled Fukushima nuclear power plant was switched off Sunday because of a chemical leak, the plant's operator said.

Hydrochloric acid, used to neutralise alkaline water being decontaminated, was found seeping from a pipe joint, Tokyo Electric Power Co (TEPCO) said in a statement.

The joint was wrapped in a vinyl bag to contain the leakage, TEPCO said, adding it was investigating the cause of the trouble.

About one litre of hydrochloric acid has been contained in the bag.

The leak was found at one of three Advanced Liquid Processing System units designed to remove radioactivity from contaminated water at the plant, where a massive earthquake and tsunami in March 2011 sent nuclear reactors into meltdown.

The systems are expected to play a crucial role in treating huge amounts of toxic water accumulating at the plant.

The troubled system was one of two units that had been in trial operation and were scheduled to go into full operation Sunday.

In late September plastic padding clogged up a drain in the same system, causing it to shut down. In October, it was halted due to a programming mistake.

Thousands of tonnes of water, used since the meltdown to cool reactors or polluted by other radioactive material, are being stored in huge tanks at the site on Japan's northeast coast.

A series of setbacks, including radioactive water leaks into the Pacific Ocean, have eroded confidence that Asia's largest utility can tame the world's worst atomic disaster since Chernobyl.

China desert lake shrinks by one-third in 13 years: Xinhua
Beijing (AFP) Nov 28, 2013
China's largest desert freshwater lake has shrunk by one-third in the last 13 years, state media said Thursday, as the country's breakneck modernisation continues to damage the environment. Northern China's Hongjiannao Lake covers 32.16 square kilometres (12.86 sq miles), less than half its size in 1969 and two-thirds of its area in 2000, Xinhua news agency said.
