After an Extended Power Uprate (EPU), a power plant was having problems with Net Positive Suction Head (NPSH) on the Feedwater Pumps. They were worried about damaging the pump, but they also didn't want to replace it. We helped them without changing the pump.

Normally, we can test impacts using FEA. In this case, FEA wasn't feasible, so we built a test stand to test missile impacts on block walls.
We found that API-650 tanks are more robust than most expect. The water in this tank absorbed 30% of the energy of a truck going 93 mph!
Eventually, most steel rusts. And most buried pipes are made from steel. So what do you do when your buried pipe gets rusty? What if the pipe leaked?
We diagnosed the failure of a nozzle check valve in an Auxiliary Feedwater System at a power plant. In summary: great valve, wrong application.
We have helped sites prepare for their TI-2515/191 inspections by using a tool we call the Compliance Matrix. Give us a call for more information.
A nuclear plant found that they needed to protect pipes from wind driven missiles. We designed a barrier system for them using 3D modeling and FEA.
Using FEA and hand calculations, we were able to help a nuclear utility evaluate RCP Seal Leakoff pipes and components for high temperature and pressure.
We worked with a local utility to help design a foundation for a transformer. The design included the spill basin for transformer oil.
We developed a testing plan to test seals and determine their water resistance. A test rig was designed which put a static head on the sample flood seals.
