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 Radiation accident in Morocco: 1984 March
A radiation alarm was transmitted only after a chemical officer and a doctor requested it. K-27 resurfaced and returned from training area to its home base using the starboard reactor. The submarine was placed at pier in Severomorsk and a depot ship continuously piped steam to the submarine to avoid cooling of heat-transfer metal in the reactor ...
Globally, there have been at least 99 (civilian and military) recorded nuclear power plant 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 nuclear energy accidents that must be reported), totaling US$20.5 billion in property damages.
Nikolai Vladimirovich Zateyev (Russian: Николай Владимирович Затеев; c. June 30, 1926 – 28 August 1998) was a Russian submariner and a Captain First Rank in the Soviet Navy, notable as the commander of the ill-fated Soviet submarine K-19 in July 1961 during the Hotel class submarine's nuclear-reactor coolant leak.

A large blaze erupted at a power substation in Pittsburgh after a reactor “catastrophically failed,” public safety officials announced.
Failure to remove decay heat may cause the reactor core temperature to rise to dangerous levels and has caused nuclear accidents. The heat removal is usually achieved through several redundant and diverse systems, and the heat is often dissipated to an 'ultimate heat sink' which has a large capacity and requires no active power, though this ...
Criticality accidents are divided into one of two categories: Process accidents, where controls in place to prevent any criticality are breached;; Reactor accidents, which occur due to operator errors or other unintended events (e.g., during maintenance or fuel loading) in locations intended to achieve or approach criticality, such as nuclear power plants, nuclear reactors, and nuclear ...
