ASME Section III Consulting

Eclipse engineers have decades of experience with applying finite element techniques to ASME Section III nuclear components. Experience plays a large role in the analysis of Section III components since proper interpretation of the Code's intention is critical.

We provide reports that detail the assumptions, boundary conditions, and comparison to Code allowable criteria.

Analytical services we provide include:

  • Applied Mechanics including linear and non-linear stress and stability analysis
  • Steady-state and transient thermal analysis
  • Fluid Mechanics / Heat Transfer analysis
Some projects with challenging criteria that we have successfully dealt with include:
  • Spent-fuel containers
  • Nuclear Heat Exchangers
  • Life Extension
  • Closures
  • Reactor vessel, heads, nozzles, and internals
  • Stratified flow in nozzle
  • Reactor seal plate
  • Steam generator tube flow evaluation
  • Steam generator tube flaw evaluation
  • Lower production-reactor core
  • Control rod drive mechanism (CRDM)
  • Tube plugging
  • Operation and Maintenance Lifting devices
  • Main feedwater nozzle
  • Production reactor core

Analysis Tools Used

  • RISA
  • Mathcad
  • EKLIPSTM FEA service
