Fukushima dumps first batch of "once-radioactive" water in sea
The operator of Japan's Fukushima on Monday began releasing previously radioactive groundwater from the crippled nuclear plant into the sea, saying a filtration process had made the discharge safe.

okyo Electric Power Co (TEPCO), which operates the plant in eastern Japan, said that on the first day it had released 850 tons of groundwater, which had become radioactive after flowing near the plant.

But it has yet to find a solution to deal with the other 680,000 tons of highly radioactive water stored on site.
This includes water used to cool reactors when they were knocked out by a towering tsunami on March 11, 2011.

Local fishermen have still not agreed to any discharge of water collected from the reactor buildings even after it is filtered.

Japan to restart nuclear reactor after two-year hiatus
Japan is due to switch on a nuclear reactor for the first time in nearly two years.

But it is deeply unpopular with the public, with Mr Abe's approval now at an all time low.

Four years on from the Fukushima disaster, 120,000 Japanese still cannot return to their homes and there are serious doubts whether the site can ever be decontaminated.

Mr Tanaka said the community around Sendai had build a clean, green local economy around seafood and agricultural produce.

But he said that was now under threat with the restart.

Of Japan's 25 reactors at 15 plants for which operators have applied for permission to restart, only five at three plants have been cleared for restart.

New UK nuclear plants under threat as 'serious anomaly' with model found in France
"Very serious anomaly" found in reactor vessel in France's Flamanville EPR nuclear plant, the same model Britain plans to use for two new plants at Hinkley Point.

A €9 billion (£6.5bn) new-generation French nuclear power plant – the same model sold to Britain – may have to be scrapped due to a faulty steel reactor vessel at risk of splitting.
It was supposed to be France's atomic energy showcase abroad, but the European Pressurised Reactor, or EPR, is threatening to turn into a nuclear nightmare with an astronomical price tag.
Designed to be the safest reactors in the world and among the most energy-efficient, the EPR has suffered huge delays in models under construction in France, Finland and China.
This week, Areva informed the French nuclear regulator that "very serious" anomalies had been detected in the reactor vessel steel of an EPR plant under construction in Flamanville, northern France, causing "lower than expected mechanical toughness values".
Pierre-Franck Chevet, president of France's nuclear safety authority (ASN), told Le Parisien the anomalies were in the "base and lid" of the vessel, which is "an absolutely crucial component of the nuclear reactor on which no risk of breakage can be taken".
The vessel houses the plant's nuclear fuel and confines its radioactivity.
The plant was already running five years later and costs have tripled.
French state-owned Areva is contracted to provide two of its EPRs to Hinkley Point in Somerset station, a development the European Commission estimates will cost £24.5 billion.

Mr Chevet confirmed that the same "production process" as for Flamanville had been used on reactor vessels destined for the British-based plants, along with two in China and one in Calvert Cliffs, Maryland, in America. "Errors have been made," he said, adding that France risked losing its nuclear expertise as the "last nuclear plant built in the country dates back 15 years". "If the weakness of the vessel is confirmed, I wouldn't hold out much hope for EPR's survival," a former nuclear safety official told Le Parisien.

Fukushima Robot Dies Three Hours After Entering Radioactive Reactor Vessel
A robot sent to inspect a reactor' containment vessel at the Fukushima Daiichi nuclear power plant stopped responding three hours into the operation. TEPCO hoped to take a look inside the vessel containing one of the three reactors, which underwent a meltdown in the 2011 nuclear disaster. A group of approximately 40 workers sent the remotely-controlled device, allegedly capable of withstanding high levels of radiation, into the vessel at 11:20 a.m. The robot stopped functioning after covering two thirds of the route at approximately 2:10 p.m., according to the Tokyo Electric Power Co.

The company did not say whether it would send another robot into the vessel on Monday, as previously planned. TEPCO's ultimate goal is to use the robot to inspect the melted fuel inside the vessel.

Fresh leak detected at Fukushima nuclear power plant
Sensors at the Fukushima nuclear plant detect a fresh leak of highly radioactive water going into the sea. The higher-than-normal levels of contamination were detected on Sunday, with sensors showing radiation levels 50 to 70 times greater than usual. Though contamination levels fell steadily throughout the day, the same sensors were still showing contamination levels about 10 to 20 times more than usual, a company spokesman said. It was not immediately clear what caused the original spike of the contamination and its gradual fall, he said.
