Durability of reinforced concrete at high temperatures
Research into the durability of reinforced concrete at high temperatures. With storage facilities designed to last for several centuries, the strength of the unprotected structural reinforced concrete would undoubtedly be one of the first problems to arise after a hundred years. CEA says it is confident that this type of concrete could last for up to 300 years, but in the CNE's opinion this has not been proven. In particular, the durability of the structure has not been proven if temporary overheating occurred during a loss of ventilation or a fire.
