What happens if a nuclear submarine gets hit?
It sinks and sits in the cold water of the deep sea. The reactors are designed to shut down automatically upon a loss of electrical power (which will happen pretty quickly if the boat floods and sinks), and emergency systems will keep the reactor from melting down.
How many crew members are on a modern nuclear submarine?
Fast Attack submarines have a crew of around 134, broken into about 120 enlisted and 14 officers, while SSBNs have an additional 16 enlisted and usually an additional officer.
How long can a nuclear subs stay underwater?
4.1. Arguments that submarines will not able to survive long enough independently. Despite various claims that nuclear submarines may stay years underwater, actual maximum known underwater duration is only 3 months. There are several reasons why longer underwater missions are problematic and we will now analyze them.
What are the advantages of nuclear-powered submarines?
The performance advantages of nuclear submarines over “conventional” (typically diesel-electric) submarines are considerable. Nuclear propulsion, being completely independent of air, frees the submarine from the need to surface frequently, as is necessary for conventional submarines.
What happens to nuclear reactors on aircraft carriers and submarines?
The USS Carl Vinson, an aircraft carrier powered by two nuclear reactors, is docked near San Diego, California. When the nuclear reactors used to power submarines and aircraft carriers are disposed of, the Department of Defense maintains and monitors the radioactive parts.
Are there any risks to civilians from nuclear submarines?
There is no reason civilians should ever encounter any exposure risk from nuclear submarines or the disposal sites that store the dismantled reactor compartments. Contact Us to ask a question, provide feedback, or report a problem.
How does a nuclear reactor protect you from radiation?
The nuclear reactor compartment is shielded to protect the crew from the radiation released by the reactor and crew access is prohibited during reactor operation. Reactor engineers wear radiation monitors that are checked regularly. They follow strict safety procedures, work in shifts and carefully plan the work to limit radiation exposure.
