This scheme has the advantages of buried, and therefore, protected insulation. The insulation debonds the grout and could be considered in conjunction wi th the planes of weakness philosophy. The major disadvantage is the effect of high temperature directly on the liner. 1 The need to protect the inner layer of concrete of a PCRV from the excessive heat generated by the reactor core has led to the development of a highly efficient but very intricate insulating system. The use of stainless steel and the welded fabrication of such a system complicates the decommissioning of a liner in active areas.

The remaining principal components of the NSSS are the reactor coolant pumps (Rep), the steam generators (SG) and the pressuriser. 1 As with the AGR, when considering PWR decommissioning, there are three major sources of radiological hazard, namely, radioactive source materials, activated materials and contaminated materials. In the PWR these hazards can be identified as follows: (a) Radioactive Source Materials These consist of the fuel assemblies which must be removed from the reactor via the existing fuel handling route before any decommissioning work can begin, after the reactor has been brought to a normal cold shutdown condition.
