The qualification process should include:
(1) a review of the procedures by experienced personnel;
(2) a review of the technical justification for the procedures and equipment;
(3) a review of the experience and qualifications required of inspection personnel;
(4) an inspection of test pieces, which should contain realistic flaws, whose size,
position, character and orientation have been chosen according to the requirements
of Section 4.3. This inspection should be conducted under conditions
(radiation protection, environment, access, etc.) which will apply on the site.
The test pieces must adequately simulate the component (shape, surface condition,
materials, manufacturing condition, etc.) to be inspected.
The equipment should be clearly defined and characterized (see Annex V) to
the extent that the stability of its characteristics can be assured, and that it can be
duplicated or replaced at a later stage without affecting the expected results of the
planned examinations.
The qualification results have to be documented. Once a procedure has been
qualified it may be used without further qualification on other similar components
and flaws.
2.5. QUALIFICATION AND TRAINING OF PERSONNEL
All in-service inspection personnel should be given qualification and training
appropriate to their level of responsibility. In spite of the different qualifications and
training practices of different operating organizations, the competence of in-service
inspection personnel should be established, preserved and verified as discussed in
Section 3.3 of the Manual on the Maintenance of Systems and Components Important
to Safety (IAEA Technical Reports Series No. 268) as applicable for in-service
inspection personnel.
2.5.1. Examination personnel should be qualified to an appropriate and recognized
standard. In particular, they should be qualified to carry out their responsibilities on
the basis that they have had experience with the same or similar examination techniques
for the same or similar materials and plant configurations as those that are
used in the in-service inspection programme. This may include examination on the
test pieces described in Section 2.4.
2.5.2. Evidence should be provided that the examinations have been carried out by
personnel qualified as stated in Section 2.5.1. Satisfactory methods by which this
could be done are by:
(1) verifying the qualification of the examination personnel and including the relevant
information in the reports of the examinations, or
