John Uhler Lemmon III was an American actor. Considered proficient in both dramatic and comic roles, Lemmon was known for his anxious, middle-class everyman screen persona in dramedy pictures, leading The Guardian to label him as "the most successful tragi-comedian of his age."
K-19 was the first submarine of the Project 658 class, the first generation of Soviet nuclear submarines equipped with nuclear ballistic missiles, specifically the R-13 SLBM. The boat was hastily built by the Soviets in response to United States' developments in nuclear submarines as part of the arms race. Before she was launched, 10 civilian workers and a sailor died due to accidents and fires. After K-19 was commissioned, the boat had multiple breakdowns and accidents, several of which threatened to sink the submarine.

The Three Mile Island accident was a nuclear meltdown of the Unit 2 reactor (TMI-2) of the Three Mile Island Nuclear Generating Station on the Susquehanna River in Londonderry Township, near Harrisburg, the capital city of Pennsylvania, United States. The reactor accident began at 4:00 a.m. on March 28, 1979, and released radioactive gases and radioactive iodine into the environment. It is the worst accident in U.S. commercial nuclear power plant history. On the seven-point logarithmic International Nuclear Event Scale, the TMI-2 reactor accident is rated Level 5, an "Accident with Wider Consequences".
A nuclear meltdown 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 or by the United States Nuclear Regulatory Commission. It has been defined to mean the accidental melting of the core of a nuclear reactor, however, and is in common usage a reference to the core's either complete or partial collapse.
A nuclear and radiation accident is defined by the International Atomic Energy Agency (IAEA) as "an event that has led to significant consequences to people, the environment or the facility." Examples include lethal effects to individuals, large radioactivity release to the environment, or a reactor core melt. The prime example of a "major nuclear accident" is one in which a reactor core is damaged and significant amounts of radioactive isotopes are released, such as in the Chernobyl disaster in 1986 and Fukushima nuclear disaster in 2011.
A scram or SCRAM is an emergency shutdown of a nuclear reactor effected by immediately terminating the fission reaction. It is also the name that is given to the manually operated kill switch that initiates the shutdown. In commercial reactor operations, this type of shutdown is often referred to as a "scram" at boiling water reactors (BWR), a "reactor trip" at pressurized water reactors and EPIS at a CANDU reactor. In many cases, a scram is part of the routine shutdown procedure, which serves to test the emergency shutdown system.
Anthony Wilford Brimley was an American actor. After serving in the U.S. Marine Corps and working odd jobs in the 1950s, Brimley started working as an extra and stuntman in Western films in the late 1960s. He became an established character actor in the 1970s and 1980s in films such as The China Syndrome (1979), The Thing (1982), Tender Mercies (1983), The Natural (1984), and Cocoon (1985). Brimley was known for playing characters at times much older than his age. He was the long-term face of American television advertisements for the Quaker Oats Company. He also promoted diabetes education and appeared in related television commercials for Liberty Medical.
Passive nuclear safety is a design approach for safety features, implemented in a nuclear reactor, that does not require any active intervention on the part of the operator or electrical/electronic feedback in order to bring the reactor to a safe shutdown state, in the event of a particular type of emergency. Such design features tend to rely on the engineering of components such that their predicted behaviour would slow down, rather than accelerate the deterioration of the reactor state; they typically take advantage of natural forces or phenomena such as gravity, buoyancy, pressure differences, conduction or natural heat convection to accomplish safety functions without requiring an active power source. Many older common reactor designs use passive safety systems to a limited extent, rather, relying on active safety systems such as diesel-powered motors. Some newer reactor designs feature more passive systems; the motivation being that they are highly reliable and reduce the cost associated with the installation and maintenance of systems that would otherwise require multiple trains of equipment and redundant safety class power supplies in order to achieve the same level of reliability. However, weak driving forces that power many passive safety features can pose significant challenges to effectiveness of a passive system, particularly in the short term following an accident.
Pilgrim Nuclear Power Station (PNPS) is a closed nuclear power plant in Massachusetts in the Manomet section of Plymouth on Cape Cod Bay, south of the tip of Rocky Point and north of Priscilla Beach. Like many similar plants, it was constructed by Bechtel, and was powered by a General Electric BWR 3 boiling water reactor inside of a Mark 1 pressure suppression type containment and generator. With a 690 MWe production capacity, it produced about 14% of the electricity generated in Massachusetts.
Three Mile Island Nuclear Generating Station is a closed nuclear power plant on Three Mile Island in Pennsylvania on the Susquehanna River just south of Harrisburg. It has two separate units, TMI-1 and TMI-2.
Dresden Generating Station is the first privately financed nuclear power plant built in the United States. Dresden 1 was activated in 1960 and retired in 1978. Operating since 1970 are Dresden units 2 and 3, two General Electric BWR-3 boiling water reactors. Dresden Station is located on a 953-acre (386 ha) site in Grundy County, Illinois, at the head of the Illinois River, near the city of Morris. It is immediately northeast of the Morris Operation—the only de facto high-level radioactive waste storage site in the United States. It serves Chicago and the northern quarter of the state of Illinois, capable of producing 867 megawatts of electricity from each of its two reactors, enough to power over one million average American homes.
A control room or operations room is a central space where a large physical facility or physically dispersed service can be monitored and controlled. It is often part of a larger command center.
Aleksandr Fyodorovich Akimov was a Soviet engineer who was the supervisor of the shift that worked at the Chernobyl Nuclear Power Plant Reactor Unit 4 on the night of the Chernobyl disaster, 26 April 1986.
The Fukushima Daiichi Nuclear Power Plant is a disabled nuclear power plant located on a 3.5-square-kilometre (860-acre) site in the towns of Ōkuma and Futaba in Fukushima Prefecture, Japan. The plant suffered major damage from the magnitude 9.1 earthquake and tsunami that hit Japan on March 11, 2011. The chain of events caused radiation leaks and permanently damaged several of its reactors, making them impossible to restart. The working reactors were not restarted after the events.
Mister Roberts is a 1955 American comedy-drama film directed by John Ford and Mervyn LeRoy featuring an all-star cast including Henry Fonda as Mister Roberts, James Cagney as Captain Morton, William Powell as Doc, and Jack Lemmon as Ensign Pulver. Based on the 1946 novel and 1948 Broadway play, the film was nominated for three Academy Awards, including Best Picture, Best Sound, and Best Supporting Actor, with Lemmon winning the latter.
The Chain Reaction is a 1980 Australian science fiction thriller film directed and written by Ian Barry. The film stars Steve Bisley and Arna-Maria Winchester. The film's plot is about an engineer badly injured in an accident caused by an earthquake. He knows that the nuclear waste will poison the groundwater and wants to warn the public.
The Taishan Nuclear Power Plant is a nuclear power plant in Taishan, Guangdong province, China. The plant features two operational EPR reactors. The first unit, Taishan 1, entered commercial service in December 2018, but was shut down from July 2021 to August 2022 to investigate and fix issues with fuel rod cladding. The second unit, Taishan 2, entered commercial service in September 2019. Delays at other EPR construction sites in Finland and France meant that Taishan was the first nuclear power plant to have an operational EPR.
Leonid Fedorovych Toptunov was a Soviet electrical engineer who was the senior reactor control chief engineer at the Chernobyl Nuclear Power Plant Reactor Unit 4 on the night of the Chernobyl disaster, 26 April 1986.
