All raw austenitic stainless steel material, both wrought and cast, used in the fabrication of the major NSSS components in the RCPB, is supplied in the annealed condition as specified by the pertinent ASTM or ASME Code 1900-2050 F for 1/2 to 1 hour per inch of thickness and water quenched to below 700°F. The time at temperature is determined by the size and type of component. 

Wrought austenitic stainless steels do not exhibit the sharp ductile to brittle transition behavior characteristic of low alloy and carbon steels. Rather, toughness losses due to irradiation tend to accumulate with increasing fluence and saturate at levels >1x10 n/m. Until recently, there was little information available to quantify the effects of radiation embrittlement on RPVIs. New information [5.2] describes the results of a fracture toughness study performed on irradiated Type 304 stainless steel reactor internal material taken from...
