Stationary Low-Power Reactor Number One, also known as SL-1, initially the Argonne Low Power Reactor (ALPR), was a United States Army experimental nuclear reactor in the western United States at the National Reactor Testing Station (NRTS) in Idaho about forty miles (65 km) west of Idaho Falls, now the Idaho National Laboratory.
Globally, there have been at least 99 (civilian and military) recorded nuclear reactor accidents from 1952 to 2009 (defined as incidents that either resulted in the loss of human life or more than US$50,000 of property damage, the amount the US federal government uses to define major energy accidents that must be reported), totaling US$20.5 billion in property damages.
In November, Russia completes the first test of the 9M730 Burevestnik, the first nuclear-powered cruise missile and the first nuclear-powered aircraft of any kind. [149] [150] 2018. In December, the Taishan 1 EPR begins operation in Guangdong, China. At 1660 MWe it is the largest nuclear reactor unit by electrical power ever. [151] [152] 2019
1993 Tomsk-7 accident at the Reprocessing Complex in Seversk, Russia, when a tank exploded while being cleaned with nitric acid. The explosion released a cloud of radioactive gas (INES level 4).

On August 6, 1945, the US dropped an atomic bomb on Hiroshima -- and newly revealed photos shed light on the preparations for the attack.
On 28 March 1979, the nuclear disaster occurred in the Three Mile Island Nuclear Generating Station. This was the first disaster in civilian nuclear power plants. By the Three Mile disaster, "China syndrome" became a vogue word, anti-nuclear movements occurred in the United States.
The plant with seven units is the largest single nuclear power station in the world, which now again is shut down due to the Fukushima accident. [47] 0: 1 Dec 2009: Hamaoka, Japan: Leakage accident of radioactive water. 34 workers were exposed to radiation: 0: Mar 2011: Fukushima Dai-ichi, Japan: The world's second INES 7 accident.
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.
