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 ...
Contrary to the TEPCO press release, aerial photos show that most of the outer building was actually destroyed. The fuel rods (both new and spent fuel) of reactor Unit 4, stored in the now exposed spent fuel pool, were reportedly exposed to air – this would have risked the melting of the nuclear fuel. However, later research found the fuel ...
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
This incident prompted the Nuclear Regulatory Commission and Customs Service to install radiation detection equipment at all major border crossings. [25] 1984 – Lost source accident in Morocco, a Ir-192 source was taken home by a laborer resulting in eight deaths in the 1984 Moroccan radiation accident. Either a drive cable detached from a ...
Off-site radiological risk may be found in the form of flooding. Many citizens in the surrounding areas have been deemed at risk of exposure to radiation due to the Chernobyl reactor's proximity to floodplains. A study was conducted in 1996 to see how far the radioactive effects were felt across eastern Europe.
During sea trials, the Soviet nuclear submarine K-27 (Project 645) suffered severe problems with its reactor cooling systems. After spending some time at reduced power, reactor output inexplicably dropped and sensors detected an increase of gamma radiation in the reactor compartment to 150 rad/h. The safety buffer tank released radioactive ...
After revelations that radioactive waste may be buried under two Bay Area parks, the cities of Albany and Berkeley submitted testing plans. Albany's was approved; Berkeley's was deemed insufficient.
Plans were considered to slice off the reactor compartment and replace it with a new one containing standard VM-A water-cooled reactors. The rebuilding or replacement of the nuclear reactor was considered to be too expensive, and also to be inappropriate because more modern nuclear submarines had already entered service in the Soviet Navy.
