The Qinshan Phase III CANDU project is owned and operated by the Third Nuclear Power Company Ltd. (TQNPC). The two units at the Qinshan Phase III site are 700 CANDU 6 reactors. Their gross output is 728 MWe each.
The total project schedule of the CANDU reactors at the Qinshan site was 81 months from contract effective date to in-service.
This 81-month schedule was made possible with the use of up-to-date integrated electronic engineering tools, including comprehensive 3-D Computer Aided Design and Drafting (CADD) systems, and Integrated Electrical and Control (IntEC) automated wiring. 3-D CADD systems allow the constructor to visualize and animate construction sequences to develop the optimum schedule before construction begins. IntEC is a management software tool for the design and installation of cable and wiring. Other tools are: Asset Information Management (AIM), a database to manage drawings, documents and project records; and the CANDU Material Management System (CMMS) to track and control materials.
Open-top construction is another tool that significantly streamlined and reduced the construction schedule. Using a very-heavy-lift (VHL) crane, major equipment was lifted over the top of the reactor building through the openings of a temporary roof. Work sequences were more efficient and flexible because activities that previously had to be conducted sequentially were able to be carried out independently of each other.
