Temperature influence on the Concrete in the spent fuel pools

| 2023:955 | Cenk Tort, Kimmo Ylinen
A nuclear power plant consists of a large number of concrete structures that are important both from a safety and operational perspective, e.g. the fuel pools. Used fuel is stored in the fuel pools for cooling before further transport to the intermediate storage.

This report summarizes the state of knowledge regarding large temperature gradients and their effects on the concrete structures in the fuel pools at nuclear power plants and present proposals for possible future research and development projects within the area.

The survey was carried out by Cenk Tort and a team from AFRY, Finland. The study was conducted among the experts working in nuclear power plants and nuclear waste storage facilities in Sweden and Finland.

The Nuclear Power Concrete Technology program is a part of the Energiforsk nuclear portfolio, financed by Vattenfall, Uniper, Fortum, TVO, Skellefteå Kraft and Karlstads Energi. In addition, the program is financed by Swedish Radiation Safety Authority (SSM) and SKB (Svensk Kärnbränslehantering AB).
