Along with components and materials, safety related documentation may also age in the sense that over time it may become out of date or even obsolete. Research reactors are frequently modified to incorporate new experimental facilities and the modifications require updating of documentation. This fact and the fact that testing and repair may also need to be changed with ageing is particularly important for the maintenance programme which is the 

Safety in operation requires that the operating personnel be knowledgeable of modified systems and the associated documentation. Therefore, training and retraining of responsible people at all levels is necessary in order to address the fact that systems, programmes and documentation have changed or may need to be changed.
