Selection and categorization of equipment susceptible to ageing

The ageing detection programme should include a list of all systems and main components of the research reactor and an analysis of their susceptibility to ageing based on the ageing mechanisms discussed in Section 3. 

The selection and categorization of equipment susceptible to potential ageing processes should be performed during the design process. Equipment and materials should be selected to minimize ageing effects. 

A recognition of the particular service conditions (e.g. pressure, temperature, radiation 

Materials of construction (e.g. carbon steel, stainless steel)  

Expected service life including an estimate of preservice use and The ease of replacement.
