If the amplitude of the low frequencies exceeds a given value, slipping surfaces (a leaded bronze plate and a stainless steel plate) are associated with each bearing pad in order to reduce the peak values transmitted to the buildings. This technique can be used whatever the spectrum (in particular the NRC spectrum); never-theless, important savings can be carried out by using a spectrum fully adapted to the seismic conditions of the site (that has been made in France with the spectrum defined by EdF). The aseismic bearing pads were used for the KOEBERG plant in South Africa (with a specific spectrum).

From a safety point of view, it constitutes the third barrier for the protection of the public against the consequences of an accident (the first barrier is the fuel cladding and the second is the reactor coolant pressure boundary). NSSS 三道屏障 three barriers- fuel cladding, pressure vessel = reactor coolant pressure boundary and the containment. During normal operation, this building has to protect the reactor coolant system against external events (such as aircraft crash, turbine missile, earth quake, etc.), and it is a shielding against reactor core radiation.
