FEA analysis nuclear vessel

We were asked to perform design and thermal, stress, vibration and fatigue analysis on vessels and components to ASME Code – as part of the Department of Energy’s radioactive waste cleanup effort. These vessels were subjected to elevated temperatures (>1400 F), seismic loads and deflagration events.

One of the vessels used an OCE-designed clamping system consisting of brackets and o-rings. Both vessels used a unique OCE-designed refractory insulating system at the vessel supports to thermally isolate the vessels from the support skids, which were not designed for elevated temperatures.

In order to perform the design and analysis of the vessels, we performed computational fluid dynamics (CFD) to determine the temperature distributions and the hydrodynamic forces due to splashing of the media during operation – as well as sloshing during a seismic event.

Structural analysis and creep-fatigue damage calculations were done using finite element analysis. In addition, all of the flanged connections were evaluated to ensure leak tightness of the connections in spite of significant loss of bolt preload due to creep relaxation.


We perform engineering and finite element analysis on equipment to AWS, API and ASME Code.
