IAEA SAFETY STANDARDS Construction for Nuclear Installations

4.7 Safety culture and its promotion should be considered as part of contractor
evaluation and monitored during the construction stage.. Monitoring and evaluation should
cover not only contractors‟ organizations but also staff.
4.8 To support the safety culture principles, there should be a process for reporting safety
concerns directly to management and the regulatory body. This process should include the
capability of anonymously reporting a non-conformance or concern.
APPLICATION OF GRADED APPROACH
4.9 A graded approach based on the relative importance to safety of each item, service or
process should be used during all construction activities. The graded approach should reflect a
planned and recognized difference in the application of specific quality assurance
requirements.
4.10 The grading process should determine the extent of the application of the
management system requirements to the construction activities.
4.11 In developing the grading approach, the following should also be considered:
(a)
The qualification of special construction processes such as welding or
non-destructive testing and the qualification of the personnel that will carry
them out;
(b)
The necessary level of detail and the need for inspection and test plans;
(c)
The safety significance of equipment, materials, procedures, records and
other documents;
