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

Serious nuclear power plant accidents include the Fukushima nuclear disaster (2011), the Chernobyl disaster (1986), the Three Mile Island accident (1979), and the SL-1 accident (1961). [11] Nuclear power accidents can involve loss of life and large monetary costs for remediation work.
At 04:15 local time the pressure in the starboard nuclear reactor's cooling system dropped to zero. The reactor department crew found a major leak in the reactor coolant system, causing the coolant pumps to fail. The boat could not contact Moscow and request assistance because a separate accident had damaged the long-range radio system.
On July 4, 1961, while K-19 was operating near southern Greenland, water pressure in the starboard nuclear reactor plummeted due to a coolant leak in an area of the reactor very difficult to access. The loss of coolant caused the reactor to begin to overheat, endangering the integrity of the control rods.
K-116 (Echo II) suffered a reactor accident (a leak of core coolant from the port reactor) in the Bay of Vladimir, Sea of Japan. Some of the crew received a large dose of radiation, but there were no fatalities. 21 August 1980 K-122 (Echo I) had a fire in compartment VII (turbo-electric) when 85 miles (137 km) to the east of Okinawa.

Erosion of the 150-millimetre-thick (5.9 in) carbon steel reactor head at Davis-Besse Nuclear Power Plant, in Oak Harbor, Ohio, USA, in 2002, caused by a persistent leak of borated water The Hanford Site, in Benton County, Washington, USA, represents two-thirds of America's high-level radioactive waste by volume.
K-431 (Russian: К-431; originally the K-31) was a Soviet nuclear-powered submarine that had a reactor accident on 10 August 1985. [1] It was commissioned on 30 September 1965. The 1985 explosion occurred during refueling of the submarine at Chazhma Bay, Dunay, Vladivostok. [2] There were ten fatalities and 49 other people suffered radiation ...
