Southern Nuclear Operating Company Uses GT STRUDL® on $10 Million Digital Turbine Controls Project
Southern Nuclear Operating Company is overseeing the licensing and construction of two new nuclear units at the Plant Vogtle site near Augusta, Georgia, US. The US$2 million Vogtle 3 and 4 units are among the first new nuclear plants built in America in more than 30 years. The existing cable tray infrastructure in the turbine building was a typical early 1980s design. At that time, the use of structural analysis was limited and computations were performed by hand.
"As part of the DTC upgrade, our engineers decided to investigate the attachment of commodities to cable trays," said Parimal Gandhi, lead engineer on the project.
Using GT STRUDL, engineers created models for portions of the cable tray infrastructure system and linked individual supports using cable tray attributes, which enabled engineers to create structural systems for multiple tray supports.
"With GT STRUDL, we saved $1 million in manpower expenses and an overall $3 million in time and resources, performing the evaluation in less than 23 days," Gandhi added.
Southern Nuclear Operating Company received the 2016 GT STRUDL Drivers of Success Award for its use of the software. The annual Drivers of Success competition recognizes innovative applications of Intergraph products, impressive project results, and significant benefits from collaboration among disciplines and the integration of the products.
The GT STRUDL cable finite element plus its cable prestress analysis feature, together with a proper analysis model, can be used to accurately predict localized stress distributions for general post-tensioned and pre-stressed concrete analysis problems.
For example, a recent use of this capability involved the analysis of a special-purpose precast, post-tensioned foundation structure for on-shore wind turbines.
GT STRUDL was found to be very effective in determining the post-tensioning sequencing and stress levels both in the cables and throughout the assembled structure itself..
GT STRUDL has been used for the analysis and design of a variety of structures such as base plates, commercial and industrial buildings, dams, bridges, offshore jackets and nuclear power plants...BUT did you know that GT STRUDL has also been used for the finite element analysis of teeth and the small bones in the ear.
