The half-life of Cs-137 is 30.08 years, so 0.0038 would remain after 241.84 years.
Nuclear fission is the working principle under which the nuclear reactors operate.
No, moderation of neutrons is not always used to slow nuclear fission. In some types of nuclear reactors, such as fast breeder reactors, fast neutrons are intentionally not moderated to slow down the fission process. These reactors operate using fast neutrons to sustain a chain reaction. However, in most commercial nuclear reactors, moderation of neutrons is employed to slow down the fission process and maintain a controlled chain reaction.
All current nuclear reactors are fission reactors, tritium has no function in a fission reactor, in standard water moderated reactors deuterium also has no function, in heavy water moderated reactors deuterium is the moderator. If we are ever able to make a fusion reactor, deuterium/tritium mix will be used as fuel.
Yes, it does so in almost all reactors
In nuclear reactors, to produce electricity
No. Our reactors are fission reactors. We haven't yet mastered fusion reactors for power.
Nuclear reactors use nuclear fission.
Nuclear fusion reactors do not exist yet as we don't know how to build them. All nuclear reactors are nuclear fission reactors.
Yes, nuclear fission reactors are very effective and can generate a lot of power. That is why nuclear fission reactors are very effecive
There are two primary design styles of fission reactors to produce electricity. Pressurized, and Boiling water reactors.
In nuclear fission reactors
there is no such thing.
Nuclear fission is the working principle under which the nuclear reactors operate.
No, nuclear fission operates all nuclear reactors. If they are power plant reactors it is used to generate electricity.
Nuclear fission occurs in fission reactors, a type of nuclear reactor, and in fission bombs, more commonly knows as atomic bombs.
water is heated up by nuclear fission and turned into steam, that steam then turns massive turbines which generate electricity.
Uranium, plutonium or thorium (for fission reactors, by far the most common type).
