The Fukushima nuclear accident was a major nuclear accident at the Fukushima Daiichi Nuclear Power Plant in Ōkuma, Fukushima, Japan, which began on 11 March 2011. The proximate cause of the accident was the 2011 Tōhoku earthquake and tsunami, which resulted in electrical grid failure and damaged nearly all of the power plant's backup energy ...
Oil fumes, natural gas, propane, coal, or any other fuel can build up inside the combustion chamber. This is especially of concern when the vessel is hot; the fuels will rapidly volatilize due to the temperature. Once the lower explosive limit (LEL) is reached, any source of ignition will cause an explosion of the vapors.
The term nuclear meltdown is not officially defined by the International Atomic Energy Agency [3] or by the United States Nuclear Regulatory Commission. [4] It has been defined to mean the accidental melting of the core of a nuclear reactor, [5] however, and is in common usage a reference to the core's either complete or partial collapse.
The Kyshtym disaster was a radiation contamination accident (after a chemical explosion that occurred within a storage tank) at Mayak, a nuclear fuel reprocessing plant in the Soviet Union. Estimated 200 possible cancer fatalities [33] 6 October 10, 1957: Sellafield, Cumberland, United Kingdom
The effects of a nuclear explosion on its immediate vicinity are typically much more destructive and multifaceted than those caused by conventional explosives.In most cases, the energy released from a nuclear weapon detonated within the lower atmosphere can be approximately divided into four basic categories: [1]
This is the largest oil spill of its kind (spill from an oil tanker) in history. January 8, 1979: Betelgeuse incident, a French constructed oil tanker which entered Bantry Bay, Ireland, exploded and killed 50 people, the disaster also caused extensive harbor damage. March 28, 1979: Three Mile Island accident. Partial nuclear meltdown.
Most people enter military service “with the fundamental sense that they are good people and that they are doing this for good purposes, on the side of freedom and country and God,” said Dr. Wayne Jonas, a military physician for 24 years and president and CEO of the Samueli Institute, a non-profit health research organization.
Implosion is the collapse of an object into itself from a pressure differential or gravitational force. The opposite of explosion (which expands the volume), implosion reduces the volume occupied and concentrates matter and energy. Implosion involves a difference between internal (lower) and external (higher) pressure, or inward and outward ...
