Sentences with phrase «nuclear reactor coolant»

Not exact matches

It's hard to articulate how major a f — up this is, but Kyle Mizokami does a good job at Popular Mechanics: Indian authorities ordered the pipe replacement because they «likely felt that pipes exposed to corrosive seawater couldn't be trusted again, particularly pipes that carry pressurized water coolant to and from the ship's 83 megawatt nuclear reactor.»

The accident could have blocked the flow of coolant gas and caused the fuel in one of the reactor's 6156 channels to melt and leak radioactivity, but it was 9 hours before Nuclear Electric decided to shut down the reactor.

Enriched uranium oxide is formed into rods and water is used both as a coolant, flowing through the reactor core to transfer heat away, and as a moderator, slowing down neutrons released by fission so that they promote further nuclear reactions.

GE Hitachi Nuclear Energy is developing the Power Reactor Innovative Small Modular (PRISM) reactor, which uses liquid sodium as a coolant.

The unit's reactor coolant loop pipe welding and the setting of other key equipment have also been completed, the Emirates Nuclear Energy Corporation (Enec) said yesterday.

Unlike the current generation of light - water nuclear reactors, PRISM uses metallic fuel, such as an alloy of zirconium, uranium, and plutonium, and PRISM's fuel rods sit in a bath of a liquid metal — sodium — at atmospheric pressure, which ensures that the transfer of heat from the metal fuel to the liquid sodium coolant is extremely efficient.

Thus, liquid sodium is the coolant of choice in fast reactors because it can effectively transfer heat away from the nuclear fuel, while at the same time maximizing the number of fast neutrons.

«What it does is it takes different sorts of fuel materials such as plutonium or used nuclear fuel, it casts that into a metallic fuel, it puts it in a reactor that has liquid sodium as a coolant — and if you have liquid sodium as a coolant then the energies of the neutrons are higher so you can use a different fuel source.

Slides also describe the roles of control rods, moderator and coolant in nuclear reactor cores.

Using a high pressure coolant in a nuclear reactor is not a good idea and lends itself to a number of accident scenarios.

It is the latest step in a sequence that began in December 2013, when the reactor was filled with its sodium coolant and received the necessary permits from Russian nuclear regulator Rostechnadzor to begin the fuel loading and pre-startup tests.

Many factories, including many nuclear reactors, use natural water sources as coolants.
