I don't think in any country it is really necessary, decisions were made on the best fuel supply foreseen in each involved country. In retrospect different decisions might have been made.
The part of a nuclear reactor where the nuclear reaction takes place is called the reactor core. It typically contains the fuel rods, control rods, and coolant necessary for sustaining and controlling the nuclear reaction.
A Nuclear Reactor.
The core of the reactor contains the nuclear fuel. Having a moderator in place within the core ensures that the nuclear fuel is processed at an accurate time duration. This can prevent serious problems from occurring within the entire nuclear reactor.
Nuclear reactor kinetics is the branch of reactor engineering and reactor physics and control that deals with long term time changes in reactor fuel and nuclear reactors.
for pressurized light water reactor type, as an example, the nuclear reactor components are * Reactor vessel (that contains the nuclear fuel and surrounded with water and contains control rod for power control and for safety) * reactor coolant pump * steam generator * reactor pressurizer * piping out of the vessel to the pressurizer, from pressurizer to steam generator, from steam generator to reactor coolant pump, and from pump back to the reactor vessel.
yes, south Africa has a nuclear reactor.
Yes, the sun is a nuclear fusion reactor.
a nuclear reactor converts binding energy into heat. a nuclear power plant uses a nuclear reactor to generate electricity.
simply, the nuclear reactor is the source of heat (or steam) for the nuclear power plant.
A breeder reactor is one type of nuclear reactor, but not a type that is in general commercial use at the present time
The heart of a nuclear power plant is the nuclear reactor.
The last nuclear reactor has not been built yet.
