Abstract
Services to the nuclear industry started at the very beginning of the nuclear industry with the construction of the first commercial units. Based on the knowledge developed in laboratories, small units were constructed and gradually extended to the large plants actually in service.
Over the past few years, reverse operations have been undertaken with the decommissioning of and the green-field operations for the oldest units.
At all stages of this work as well as during the main outage operations, external firms have been involved. Progressively these companies have built up specific knowledge including both the technical requirements identical to those of non-nuclear interventions (mechanical, electrical, engineering…) and the more nuclear-related ones (quality and safety requirements, radwaste management, radiological aspects, alara principles…).
