Interim Storage

Dry interim storage is less costly and easier to maintain than wet storage. Cooling of the spent fuel is provided by the natural circulation of the ambient air or by forced circulation of inert gas. In some storage facilities, the fuel is placed into module boxes cooled by inert gas that are stored in special concrete cellars (this setup is used in, e.g., Fort Saint Vrain in the USA or Wylfa

How Energy Storage Works

Because nuclear power plants are not designed to ramp up or down, their generation is constant at all times of the day. When demand for electricity is low at night, pumped hydro facilities store excess electricity for later use during peak demand. Energy storage is also valued for its rapid response–battery storage can begin discharging

What is Nuclear Energy? The Science of Nuclear Power

Nuclear fission is a reaction where the nucleus of an atom splits into two or more smaller nuclei, while releasing energy. For instance, when hit by a neutron, the nucleus of an atom of uranium-235 splits into two smaller nuclei, for example a barium nucleus and a krypton nucleus and two or three neutrons.
