2.2.2. The In-Service Inspection Manager should ensure that the in-service inspection
programme, both as a whole and in detail, is reviewed in the light of experience
and of changed local plant conditions, and revised as necessary.
2.3. ESTABLISHMENT OF THE IN-SERVICE INSPECTION PROGRAMME
The In-Service Inspection Manager should develop the in-service inspection
programme. He should be experienced in nuclear power plant in-service inspection
practices.
Development of the plant in-service inspection programme should be initiated
early in the design phases of the plant. The primary reason is to ensure that the
requirements of the in-service inspection programme will be incorporated into the
design and construction details of the plant. During the design phase, the interaction
with the design group should include the considerations specified in Section 2 of
50-SG-O2 and should also address the following factors:
(1) location, size, layout, habitability and personnel safety features of facilities for
the calibration and maintenance of ISI equipment;
(2) location, size and, layout of storage facilities for ISI equipment;
(3) inspectability characteristics, arrangement, location, environment, shielding,
sheltering and access to systems and components;
