Business, Thought, and Management Articles --- Nuclear Power --- Fission Energy
Nuclear power is basically the power generated by the nuclear reaction. Nuclear reaction has mainly nuclear fission and nuclear fusion. Nuclear power generation that is operating currently in commercial takes advantage of the fission energy of uranium-plutonium.

Atom is the smallest unit of an element. The word atom originally seems to be something that can not be decomposed any more. Atom consists of electrons and nuclei, nuclei are made from protons and neutrons. Nuclei usually is very stable, does not divide easily.
However, the heavy and relatively unstable nuclei can divide by absorbing a neutron.
Fission is the phenomenon that the nuclei divide. Huge energy conversion occurs by dividing the nucleus. Uranium and plutonium will generate an explosively large energy by nuclear fission.
When the fission occurs, neutrons are released. When the released neutrons are absorbed in other nuclei, further fission will occur. In this way it is possible to cause a chain react.
Atoms generated by nuclear fission, will mostly have radioactivity. It means that a large amount of radioactive material are generated with explosive energy during a chain reaction of nuclear fission.
Fission energy is very large. So it attracted attention and studied as an energy source for military or business use from before.
However, risk of explosive energy and a large amount of radioactive material generated from chain reaction have a lot of issues. Voices that questioned its use are also not uncommon.
Fission Energy
Nuclear power is basically the power generated by the nuclear reaction. Nuclear reaction has mainly nuclear fission and nuclear fusion. Nuclear power generation that is operating currently in commercial takes advantage of the fission energy of uranium-plutonium.
Atmic Reactor
Atomic reactor is the equipment to make continuously stable nuclear reaction. Fission will generate a large amount of radioactive substance with explosive energy. Nuclear power generation is to generate electricity using the heat energy by controlling the nuclear reaction in the reactor.
Power Generating Plant
Power generation plant will generate the power by the generator. In order to move the generator, you need the power. In the case of nuclear power plant, it creates the steam that was heated by the nuclear reaction energy, thereby turns the turbine.
Radioactive Waste
When operating nuclear power plant, radioactive waste will be made. Radioactive waste is waste that contains radioactive substances. Processing of radioactive waste has concerns of its risk and the impact to the environment, it has become a major issue of nuclear power.
Workers and Their Health
Those who supports the operation of nuclear power plant are the workers who work there. Workers sometimes have to work side-by-side with danger at high radiation area. And their health management is a big issue.
Safety Design and Quality Management
Fission energy is explosively large, nuclear reaction is dangerous accompanied by radioactivity. So, variety of safety design shall be applied to nuclear power so that any accidents or failures shall never occur.
Correspondence in Case of Accident
If the accident occurs in a nuclear power plant, it will have a significant impact on a wide range of people. Depending on the correspondence in case of accident, it can harm many people's lives and health, cause pollution in wide area and ocean, and will be criticized from the international community.
Decommissioning of Nuclear Power Plant
The nuclear power plant will be gradually aging by continuous long-term operation. Outdated nuclear power plants will have to stop the operation, and must be decommissioned. The nuclear power will also have a big issue for this "decommissioning".
The Future of Nuclear Power
How the future of nuclear power will be that have variety of issues? How the nuclear power should be? Let's think about he future of nuclear power here.
Should the Nuclear Power Be Eliminated?
There are opinions that we should be without nuclear power. That says, we should abolish the nuclear power plants because nuclear power is dangerous, has concerns like accidents and radioactive waste, and it is not promising as an energy source.
Future of Energy Policy
How our energy policy will be in future? What should we consider the use of energy from now? Let's think about the future of energy policy here.
