Modelling modules coordinates construction

31 October 2013

Advanced computer modelling is helping the construction of new nuclear power plants in the USA. Teams making power plant modules at separate sites are working from the same plant model, which is updated daily.

There are two AP1000 units under construction at Vogtle and VC Summer in Georgia and South Carolina respectively, with a further unit in preparation at each site. The modular design of AP1000 allows engineers to create parts of the plant before construction officially begins.

Managing the process for Southern Company and SCE&G is Chicago Bridge & Iron (CB&I). In tandem with plant designer Westinghouse's WEMMEX application, CB&I uses Bentley Systems' i-models in planning the construction work packages to revise some 8000 3-D design models every day. It allows engineers to accommodate alterations from the basic design necessitated by other parts of the construction process. The project application was presented at a Bentley Systems conference in London on 29 October by CB&I executives Larry Lynch and Mike Parsons.
