In a nuclear fission reaction, a freely moving neutron undergoes neutron capture and initiates the nuclear fission of a fuel atom.
a neutron is absorbed by an atom’s nucleus. (apex)
If things go according to plan, the neutron encounters a fissionable atomic nucleus and then undergoes what is called neutron capture. That's the next step in the process. The presence of that neutron in the nucleus destabilizes the nucleus (more than it already is as that nucleus is radioactive and unstable anyway). In an extremely short period of time the instability results in nuclear fission. The nucleus splits.
The 235U fuel releases neutrons, which will continue the chain reaction. It also releases heat, which is carried off in the coolant and (usually) used to generate steam to spin turbines to generate electricity.
Technetium is now produced in nuclear reactors. Neutrons collide with atoms of uranium or plutonium to form new elements. The technetium is then converted to a compound called ammonium pertechnate (NH 4 TcO 4 ). That compound is then treated with hydrogen gas to obtain pure technetium metal.Technetium has never been found on Earth. It has, however, been found in certain types of stars.
The nuclear membrane begins to fade from view during prophase, which is the first stage of mitosis. As the cell prepares for division, the nuclear membrane breaks down to allow the chromosomes to move freely within the cell.

When a freely moving neutron is introduced to a nuclear fuel like uranium, it can be absorbed by the nucleus of the fuel atom, causing it to become unstable and split into two or more smaller atoms, releasing energy and more neutrons in the process. This is known as nuclear fission, and it can lead to a chain reaction if the released neutrons go on to collide with other fuel atoms and cause them to undergo fission as well.

A nuclear fuel rod is a tube filled with nuclear fuel. The tube part is made of material that allows neutrons to pass freely through, so the fuel can undergo reaction unhindered. The rods are put together in groups called bundles, which are attached together so they can be handled together. There is a link below to the section in an article on nuclear fuel that explains the fuel rods. Pictures are there as well.
It increases; more freely moving particles.
Very freely; Newton's law of action and reaction comes into full play.

To be able to monitor unconditionally all nuclear tests. If nuclear tests are allowed freely, no third party would have rights to observe and provide expertise, no error reporting available, no standard recollection of facts, no responsibility recorded.
DNA in a eukaryote is surrounded by a nuclear membrane, hence forming a distinct nucleus whereas the DNA in a prokaryote is not bounded by a nuclear membrane and floats freely in the cytoplasm.
