Custom Engineering & Testing

Full scale diesel fuel transfer system experimentBackground

Day to day operation of a nuclear power, chemical processing or industrial plant requires continuous monitoring, checking and adjusting of the numerous components that enable the plant to operate safely and efficiently. When issues arise or problems occur the question becomes one of what to do.  

Detailed computer codes, hand calculations, separate effects testing and engineering judgment are usually the tools of choice but not necessarily practical when schedules are tight and analysis via computer codes is either impossible or extremely difficult. In these situations, each hour lost costs money.  A practical solution is to perform a scaled or full-sized test that replicates the exact set of conditions that are of concern. 


  • Plant specific evaluations
  • Solid viable alternative to analytical solutions
  • End product will be more readily accepted by authorities
  • Able to address challenging problems
  • Results can be used to validate, refine and/or benchmark analytical tools
