– The necessary design calculations, drawings and specifications for the completeproject.– The staff training programme designed to enable staff to cope with unusual operationsduring the implementation of the project. (The staff should also be informed about thespecial safety considerations and provisions applying during the various stages of theproject.)– The preparation of all documentation, such as procedures for the amended state of thereactor, including any new or temporary emergency procedures and the associatedstaff training programme.– A commissioning plan to verify that the objectives have been achieved.– An outline of the decommissioning plan.– A special surveillance programme, including ageing management and In ServiceInspection requirements, if necessary (see para. 7.6).
