New York Nuclear Reactor

An errant bird dropping was the likely cause of a temporary shutdown of part of the Indian Point nuclear plant outside New York City, the operator has concluded.

A nuclear power plant north of New York City has leaked water contaminated with radioactive tritium into the groundwater below the facility, sparking an investigation by state officials, Governor Andrew Cuomo said on Saturday.

A nuclear power reactor 40 miles (65 km) north of New York City was shut down on Saturday after a transformer fire, but officials said the Indian Point plant was stable and there was no threat to residents nearby.

A string of aggressive gestures by Iran this week -- assassination attempts on Israelis living abroad that were attributed to Tehran, renewed posturing over its nuclear program and fresh threats of economic retaliation -- suggest that Iranian leaders are responding frantically, and with increasing unpredictability, to the tightening of sanctions by...

Highly radioactive water is leaking directly into the sea from a damaged pit near a crippled reactor at the Fukushima Daiichi nuclear power plant, safety officials said Saturday, the latest setback in the increasingly messy bid to regain control of the reactors. Although higher levels of radiation have been detected in the ocean waters near the pla...

Highly contaminated water is escaping a damaged reactor at the crippled nuclear power plant in Japan and could soon leak into the ocean, the country's nuclear regulator warned on Monday.The discovery poses a further setback to efforts to contain the nuclear crisis as workers find themselves in increasingly hazardous conditions. In another new findi...

Japan's troubled effort to contain the nuclear contamination crisis at its stricken Fukushima Daiichi plant suffered a setback on Sunday when alarmingly high radiation levels were discovered in a flooded area inside the complex, raising new questions about how and when recovery workers could resume their tasks.Tokyo Electric Power Company, the oper...

Japanese officials began encouraging people to evacuate a larger swath of territory around the Fukushima Daiichi nuclear plant on Friday as new signs emerged that parts of the crippled facility are so damaged and contaminated that it will be hard to bring the plant under control soon. The authorities said that they would now assist people who want ...

Japan's effort to contain the crisis at the Fukushima Daiichi nuclear plant suffered a setback, an official said on Friday, citing evidence that the reactor vessel of the No. 3 unit may have been damaged.The development, described at a news conference by Hidehiko Nishiyama, deputy director-general of the Japan Nuclear and Industrial Safety Agency, ...

Just a month before a powerful earthquake and tsunami crippled the Fukushima Daiichi plant at the centre of Japan's nuclear crisis, government regulators approved a 10-year extension for the oldest of the six reactors at the power station despite warnings about its safety. The committee reviewing extensions pointed to stress cracks in the backup di...

Japan appeared to make moderate progress in stabilizing some of the nuclear reactors at the stricken Fukushima Daiichi power plant on Sunday, but at the same time it disclosed new signs of radioactive contamination in agricultural produce and livestock.The government said it was barring all shipments of milk from Fukushima Prefecture and shipments ...

The warnings were stark and issued repeatedly as far back as 1972: If the cooling systems ever failed at a "Mark 1" nuclear reactor, the primary containment vessel surrounding the reactor would probably burst as the fuel rods inside overheated. Dangerous radiation would spew into the environment. Now, with one Mark 1 containment vessel damaged at t...

Even as workers race to prevent the radioactive cores of the damaged nuclear reactors in Japan from melting down, concerns are growing that nearby pools holding spent fuel rods could pose an even greater danger. The pools, which sit on the top level of the reactor buildings and keep spent fuel submerged in water, have lost their cooling systems and...

Japan's nuclear crisis verged toward catastrophe on Tuesday after an explosion damaged the vessel containing the nuclear core at one reactor and a fire at another spewed large amounts of radioactive material into the air, according to statements from Japanese government and industry officials.In a brief morning address to the nation Tokyo time, Pri...
