Design of Concrete Containments

– Focus on Integrity and Tightness

Wednesday January 28, 2015

Venue: Swedish Radiation Safety Authority, Solna Strandväg 96, Stockholm, Sweden

The containment is designed to prevent the release of radioactive substances in case of a pipe break and to protect the nuclear reactor from external events, for example earthquakes, airplane impact.Depending on the type of reactor (boiling- or pressurized water), different designs are chosen regarding size, shape and function of the reactor containment. To meet those conditions, the containment must be able to withstand hot steam at high pressure and remain leak tightness.

This seminar aimed at providing knowledge about the requirements that have been set for concrete containments, how the design was approached – overall and in detail – to fulfil these requirements and their differences compared to conventional civil concrete structures. The focus of the seminar is on how to fulfil the requirements on integrity and tightness of the reactor containment.

The seminar was arranged by the Energiforsk Concrete Research Program Nuclear, financed by E.On, Fortum, Karlstads Energi, Skellefteå Kraft, The Swedish Radiation Safety Authority, TVO and Vattenfall.
