(4) system and component area habitability factors (noise, illumination, radiation,
temperature, humidity, personnel safety);
(5) provisions to minimize radiation exposure of personnel during inspection and
to reduce radiation levels resulting from such sources as accumulations of
radioactive materials;
(6) plant features (elevators, cranes, lifting and hoisting provisions, personnel
safety, communications);
(7) human anthropometries and strength; .
(8) Need for proper and unambiguous marking, labelling and coding.
During plant construction and commissioning, the in-service inspection
programme should be established and implemented to perform pre-service inspection
on all equipment included in the in-service inspection programme.
The performance of some pre-service inspection activities for various systems
and components during construction or commissioning may be the responsibility of
the vendor or constructor. However, the In-Service Inspection Manager of the operating
organization will be responsible for ensuring that those in-service inspection
activities are adequately performed and the appropriate records transferred to the
operating organization.
The In-Service Inspection Manager also has to ensure that all appropriate
records pertaining to construction and pre-service inspection are transferred to the
operating organization file and maintained according to QA requirements.
The in-service inspection activities as a function of time during design, construction,
commissioning and operation will be determined and routinely updated.
The in-service inspection personnel are hired, trained and qualified commensurate
with the in-service inspection activities load. These activities should include the
preparation of procedures, the procurement of in-service inspection equipment and
the qualification and calibration of in-service inspection equipment as appropriate.
2.4. QUALIFICATION OF PROCEDURES AND EQUIPMENT
Examination and testing procedures are intended to ensure the required
capability, reliability and reproducibility of the examination system. Their qualification
consists of a demonstration of the detection and correct evaluation of all defects
equal to or larger than the acceptance standard. (Some Member States may consider
that the detection and correct evaluation of all reportable defects, see Section 3.4.1,
should be qualified even if they are within the acceptance standard.) Procedures
should define all equipment, probes, consumables, cables, instruments (including the
'recording system', etc.) and the methodology for the decision process to be used
during the inspection.
