Although personas are fictitious, they are based on knowledge of real users. Some form of user research is conducted before they are written to ensure they represent end users rather than the opinion of the person writing the personas. Below is a sample persona for an intranet project.
Nuclear energy is usually found in nuclear power stations. Countries that have a number of operating stations include the USA, Canada, UK, France, Japan, and Russia. Some other countries have one or two stations. Strictly speaking, power is the rate of energy use â¦ . So nuclear energy of a fixed amount is released for every fission that takes place, but power depends on how many fissions occur per second.
Some examples of common radiactive isotopes found naturally that have this property are 40K (potassium-40) which is present in seawater and many salts, 14C (Carbon-14) and Uranium and Thorium. Nuclear Fission energy is released when a very heavy atomic nucleus absorbs a neutron and splits into two lighter fragments. The energy release in this process is enormous. It is 10 million times greater than the energy released when one atom of carbon from a fossil fuel is burned.
