Articulating Solar Array
We were able to help our client save over $40,000 on the design and construction of an articulating solar array. 
Ballistic Testing
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.
Check Valve Failure Analysis
We diagnosed the failure of a nozzle check valve in an Auxiliary Feedwater System at a power plant. In summary: great valve, wrong application.
Condensate and Feedwater Upgrade
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.
Custom Tool Design and Fabrication
Custom Tools A tool is a device or handheld implement that aids in accomplishing a task. When tasks become complex, the tools available at your local hardware store may not be the best choice. XCEED works closely with you and your maintenance staff to develop ideal, custom tools to solve your toughest problems, eliminate occupational hazards, […]
Double Wall Piping System for Deuterium Gas
Project Overview: XCEED developed, designed, and analyzed a double wall piping system specifically for the safe transport of deuterium gas. This system was crucial for ensuring the integrity and safety of the gas handling processes within the facility. Design and Routing: Compliance and Analysis: Outcome: The successful development and analysis of the double wall piping […]
Flood Penetration Qualification
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.
Fukushima FLEX Compliance Matrices
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.
Helium Covergas System Enhancement [Blower Replacement]
Helium Covergas System Enhancement Overview: A research facility uses helium covergas to minimize contamination of the process fluid. The existing system, a vintage 1960s circulating blower system, was deemed outdated and inefficient. Investigation and Technology Selection: XCEED conducted a thorough evaluation of several modern blower/compressor technologies to replace the antiquated blower system. After careful consideration, […]
Large Ballast Tank (LBT) Enhancements
Overview: The Large Ballast Tank (LBT) serves as a surge volume for off gas from a critical refrigeration cycle. The temperature of the outdoor tank is closely linked to the system pressure, and variations in temperature can significantly impact experimental results. HVAC Calculations: XCEED conducted detailed HVAC calculations for the outdoor tank to assess the […]
Missile Barrier Design Review
We worked with a nuclear plant to optimize a shear wall design. The optimized design reduced the amount of rebar by about 30%.
Modular Platform Design
A research institution required a modular, hand-assembled maintenance platform to service a component that is accessed only infrequently. The design challenge included the need for a large central opening and the ability to adapt to three specific elevation levels. Design: Taking into account standard maintenance practices, crane hook height limitations, and obstructions caused by nearby […]
Preventing Fatigue Failure
Pumps and compressors vibrate. It’s a natural phenomena for anything that rotates or reciprocates, and it’s unavoidable. Normally, it’s not a problem. Until the vibrations hit resonance. When you have a pump or system operating at resonance, it can cause a fatigue failures. Recently, we found an example of this at a nuclear utility. They […]
RCP Seal Leakoff
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.
Steam Pipe Integrity Evaluation
Tornado generated missiles can wreak havoc, especially on a nuclear power plant. We helped one site design and optimize a protection system.
Tank Impact Evaluation
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!
Tornado Missile Barriers
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.
Transformer Foundation Design
We worked with a local utility to help design a foundation for a transformer. The design included the spill basin for transformer oil.
Trenchless Pipe Rehabilitation
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?
