Why are nuclear powered submarines better?
The nuclear reactor on board a submarine allows it to operate at high speed for long periods of time with unlimited range. Nuclear power provides attack submarines with a sustained submerged speed of more than 30 knots, considerably greater than any contemporary diesel submarine.
What are the three main parts of a nuclear reactor?
Components of a nuclear reactor
- Fuel.
- Moderator.
- Control rods or blades.
- Coolant.
- Pressure vessel or pressure tubes.
- Steam generator.
- Containment.
What was the main reason for Chernobyl accident Mcq?
What was the main reason for Chernobyl accident? Explanation: The Chernobyl accident in 1986 was the result of a flawed reactor design that was operated with inefficiently trained personnel.
How does a nuclear powered submarine work?
Nuclear Submarine Propulsion System. A nuclear reactor is an air tight enclosed space wherein uranium atoms split to generate huge amount of energy. When the uranium atoms split, they release massive energy along with heat and radiation. This released heat is channelized to propel the submarine.
What are the weaknesses of nuclear-powered submarines?
The stealth technology weakness of nuclear submarines is the need to cool the reactor even when the submarine is not moving; about 70\% of the reactor output heat is dissipated into the sea water.
How dangerous is it to recover a nuclear submarine reactor?
There are currently 8 sunken nuclear submarines around the world. They all contain a nuclear reactor in various states of damage or decay. Here’s a list: Recovering a damaged reactor is much more dangerous than simply leaving it in place. This is obviously not the preferred way to deal with submarine reactor cores, but it’s surprisingly benign.
What is a nuclear reactor?
A nuclear reactor is an air tight enclosed space wherein uranium atoms split to generate huge amount of energy. When the uranium atoms split, they release massive energy along with heat and radiation. This released heat is channelized to propel the submarine. This is generally done in two ways –.
