DEGRADATION OF BUILDING MATERIALS OVER A LIFESPAN OF 30 - 100 YEARS
Following preliminary visits to four Magnox Nuclear Power Stations, a study was made of existing Central Electricity Generating Board (CEGB) reports on the condition of buildings at eight Power Stations, including both Nuclear and Coal-fired. Sampling of building materials, non-destructive testing and inspections were carried out at Trawsfynydd, Oldbury and Dungeness "A" Magnox Power Stations, and the samples were subsequently laboratory tested. From the results of this work it can be concluded that little major deterioration is likely to occur in the reactor buildings at Trawsfynydd and Oldbury over the next 50 years and at Dungeness "A" for at least 25 years, assuming reasonable maintenance and the continuation of suitable internal temperatures and relative humidities. Because of the limitations on taking samples from, and tests on, the reactor biological shields and prestressed concrete vessel, no sensible forecast can be made of their potential life in the 75-100 year range.
