Description
The transient behaviour of the SNR-2 reactor roof following a breakdown of forced cooling was analysed. Additional to the investigation of the reference roof design with open annular gaps and without insulation underneath alternatives were examined regarding varied insulation measures of stepwise increased effectiveness. From these analyses one can derive that due to several effects insulation does not reduce maximum temperatures and temperature differences inside the roof. Improvements in roof design should therefore predominantly be directed towards a better temperature equilization e.g. by: a better thermal coupling between different parts of the roof; enhancing natural convection inside the roof cooling circuit.
