Entergy Nuclear applied Dassault Systemes PLM solutions at its Waterford 3 plant to plan three major maintenance projects. CATIA models combined with laser scan data created accurate 3D environments. DELMIA simulations tested removal sequences for a 57-ton reactor coolant pump motor, a fire panel analysis, and in-core instrumentation thimble replacement. The simulations uncovered two obstructions that would have added 1-2 outage days and $1-2 million in replacement power costs.

Key takeaways

3D PLM simulation identified obstructions before execution, avoiding 1-2 days of added outage time

Virtual modeling replaced physical mockups, lowering project preparation costs

Radiation exposure scenarios can be tested in DELMIA to minimize worker dose

Digital simulations capture procedures for training and knowledge transfer to new staff

Waterford 3 is now licensing CATIA and DELMIA for in-house future modeling work
