Abstract

Since the early sixties, inspection of structural components has been harmonized through prescriptive codes and standards. An important example is the one of the in service inspection (ISI) of nuclear reactor components (using the ASME and RSEM codes, KTA rules, etc). Each of these different codes prescribe procedures which are based on precise nondestructive evaluation (NDE) techniques, defined in detail. New techniques are difficult to introduce in such a code even if more adapted to the defects to be detected or allowing a reduction of the inspection effort, due to the difficulty in satisfying the condition of equivalence or superiority of the new proposal and this to the satisfaction of the regulatory authority. This impedes the effective competition between service vendors proposing standard procedures and those proposing new technologies.
