Design and analyses of the reinforced concrete support corbels for the polar crane in the reactor containment building of Sizewell 'B' power station

The polar crane within the primary containment building at Sizewell 'B' Nuclear Power Station will be supported by a ring of forty-eight individual reinforced concrete corbel units, separated from each other by 20mm gaps, and anchored, by reinforcement, into the containment building wall. After initial design work undertaken to determine the amount and layout of reinforcement required in each unit, a section of wall and corbel was analysed to assess both stresses in the corbel units and the effect on the containment wall.
