Nuclear reactors line the riverbank at the Hanford Site along the Columbia River in January 1960. This image of the core from the SL-1 disaster, Idaho Falls, Idaho, USA , served as a reminder of the necessity for proper reactor practice and safeguards.
The 1979 Three Mile Island accident in Pennsylvania was caused by a series of failures in secondary systems at the reactor, which allowed radioactive steam to escape and resulted in the partial core meltdown of one of two reactors at the site, making it the most significant accident in U.S. history.
Soviet submarine K-19 reactor accident 1961, July 4 More than 30 people were over-exposed to radiation when the starboard reactor cooling system failed and the reactor temp rose uncontrollably. Emergency repairs ordered by the captain successfully cooled the reactor and avoided meltdown, but exposed the workers to high levels of radiation. [17] 8
The world's first nuclear reactor meltdown was the NRX reactor at Chalk River Laboratories, Ontario, Canada in 1952. [22] The worst nuclear accident to date is the Chernobyl disaster which occurred in 1986 in the Ukrainian SSR, now Ukraine. The accident killed approximately 30 people directly [23] and damaged approximately $7 billion of property.
A magnitude 9.0 earthquake and tsunami on March 11, 2011, damaged the Fukushima Daiichi plant’s cooling systems, causing three of its reactors to meltdown, releasing radiation and driving ...
— March 11, 2011: A magnitude 9.0 earthquake strikes off the coast of northeastern Japan, triggering a towering tsunami that smashed into the Fukushima nuclear plant, knocking out power and ...
Japan marked the 13th anniversary of the massive earthquake and tsunami that triggered a nuclear meltdown and left large parts of Fukushima prefecture uninhabitable on Monday with a minute of ...
A nuclear meltdown (core meltdown, core melt accident, meltdown or partial core melt [2]) is a severe nuclear reactor accident that results in core damage from overheating. The term nuclear meltdown is not officially defined by the International Atomic Energy Agency [3] or by the United States Nuclear Regulatory Commission. [4]
