ISFSI Santa María de Garoña

Licensing of radiological calculations of the Individualised Temporary Storage (ATI) of the "Santa María de Garoña" Nuclear Power Plant.

Calculations carried out using the MAVRIC module of the SCALE package

Licensing before the Nuclear Safety Council (CSN) of radiological calculations due to the storage of 10 spent fuel casks at the ISFSI of the “Santa María de Garoña” NPP, in order to comply with instruction IS-29, which defines the dose rate limits at the boundary of the controlled area of the ISFSI for its operation to be authorised.

The calculations were performed using the MAVRIC module of the SCALE package, modelling the fuel elements (rod to rod), the container, the ISFSI and the topographic profile of the terrain. The total dose rate at the limiting point has been obtained from the contributions of each of the radiation sources that are stored in the containers, i.e. fuel photons, fuel neutrons, activation photons and secondary photons.
