Work on nuclear power plant projects is subject to strict quality assurance requirements.

With the OL3 project, as well as the usual design documents, the designers also produced governing documents on quality assurance which were checked by the client and authorities:

— Work specifications, such as defining specific works, indicating training required

— Quality control plan — checklists defining what checks are to be conducted and how, and stating who is responsible in each case

Based on these documents, the contractors involved produce work plans, which essentially extrapolate the designers’ quality control plans with specific construction aspects (materials, work rates, etc.).

Work plans are produced based on the overall quality assurance system, referencing the underlying performance documents. In substantive terms, they include the working resources and procedures required to perform tasks, the project organisation stating who is in charge of performing work and what to do in the event of problems. They also include risk assessments on individual relevant issues.
