Most current power plants use water, but heavy water, graphite, hydrocarbons, etc. could be used instead.
What else can I help you with?
Which is used as moderator in nuclear reactor?
Control rods are used as moderators in nuclear reactors to regulate the rate of fission reactions by absorbing neutrons. By adjusting the position of the control rods, the reactor can be managed to sustain a controlled chain reaction.
What is a bare reactor?
It is a nuclear reactor without reflector, consisting only from fuel and moderator.
Why does the core of the reactor have a moderator?
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.
Why moderator is not used in case of fast breeder reactor?
Moderator is not used in case of fast breeder reactor because there is no need to slow down neutron energy. Nuclear fission takes place at high energy of neutrons.
Why normal water is not used as moderator in nuclear reactor?
Normal water, or light water, absorbs too many neutrons to be an effective moderator in a nuclear reactor. This absorption can make it difficult to sustain a nuclear chain reaction. Instead, reactors often use heavy water or graphite as a moderator, which have lower neutron absorption rates.
Why is the moderator important in a nuclear reactor?
The moderator is used to slow down the neutrons present in the core of the reactor. Normally the neutrons produced as the nuclear fuel (e.g. uranium) is fissioned are travelling too fast to produce a sustained chain reaction. Some examples of moderators are cadmium, heavy water and graphite.
In a nuclear reactor the moderator is usually made of graphite placed between the fuel rods used to slow down neutrons all of the above none of the above?
The moderator in a nuclear reactor is usually made of graphite, which is used to slow down neutrons. So, the correct answer is "all of the above".
Can a reactor without moderator is present?
Yes, they are fast nuclear reactors
Do moderator in nuclear reactor slows down the neutrons emitted during fission?
Yes, it is the main moderator function in what is called "thermal nuclear reactors"
The moderator used in the nuclear reactor at Madras atomic power station in Kalpakkam is?
The moderator used in the nuclear reactor at Madras Atomic Power Station in Kalpakkam is usually heavy water (deuterium oxide) or light water (ordinary water). These moderators are important for slowing down neutrons produced during nuclear fission reactions to sustain the chain reaction in the reactor.
Do substance is used as moderator in modern nuclear reactor?
Water (H2), or heavy water (D2O). Sometimes, liquid sodium is used.
Can you use tritium water as moderator in nuclear reactor?
Yes, tritium water can be used as a moderator in a nuclear reactor. However, tritium itself is a radioactive isotope of hydrogen, so careful handling and safety measures are required due to its potential health risks. Research is being conducted on the use of tritium in nuclear fusion reactors, but it is not commonly used as a moderator in fission reactors.
