The radio nuclei present in the damaged fuel are supposed to be released into the main heat transport system and after that into the containment building in the worst case scenario. Assessing the radioactive nuclei maximum release is the purpose of the present paper. | Beyond designed functional margins in CANDU type NPP.

European Union s energy roadmap up to year 2050 states that in order to have an efficient and sustainable economy with minimum or decreasing greenhouse gas emissions along with use of renewable resources each constituent state has the option for nuclear energy production as one desirable option. Every scenario considered for tackling climate change issues along with security of supply positions the nuclear energy as a recommended option an option that is highly competitive with respect to others. Nuclear energy along with other renewable power sources are considered to be the main pillars in the energy sector for greenhouse gas emission mitigation at European level. European Union considers that nuclear energy must be treated as a highly recommended option since it can contribute to security of energy supply. Romania showed excellent track-records in operating in a safe and economically sound manner of Cernavoda NPP Units 1 amp 2. Both Units are in top 10 worldwide in terms of capacity factor. Due to Romania s need to ensure the security of electricity supply to meet the environmental targets and to move to low carbon generation technologies Cernavoda Units 3 amp 4 Project appears as a must. This Project was started in 2010 and it is expected to .
