Entergy Nuclear

Industry: Energy & Materials

Entergy Nuclear is a division of entergy headquartered in Jackson, Mississippi. Entergy Nuclear and its nearly 6,000 employees manage the second-largest fleet of nuclear reactors in North America, with 11,022 megawatts of generating capacity – roughly equivalent to the peak power demand of New york city in 2003. It operates ten commercial nuclear power sites with a total of 12 reactors.

The Challenge

  • Upgrade existing nuclear plants to double lifespan.
  • Reduce business risk and improve safety through superior planning.
  • Shorten maintenance outages to save $1 million/day.
  • Transfer knowledge to a new generation of workers.

Dassault Systèmes Response

Entergy Nuclear chose PLM (Plant Lifecycle Management) solutions from Dassault Systèmes (DS) for three projects at its Waterford 3 plant near New orleans, Louisiana. Dassault Systèmes Industry Services (DSIS), the Professional Services arm of Dassault Systèmes, conducted virtual modeling and simulation for the projects, leveraging CATIA to create virtual models, DELMIA for virtual simulation, and DS-partner solution AREVA laser scanning to capture updates to the plant not reflected in the original plans.


  • $1 million to $2 million saved Discovering unrecognized obstructions cut 1-2 days from RCP motor replacement outage at cost of $1 million/day.
  • Safer maintenance operations Digital simulations facilitate improved worker training and help minimize radiation exposure.
  • Lower-risk operations By helping to ensure that every possibility has been anticipated, DS PLM helps reduce the risk of unanticipated delays.
  • Lowered investment in physical mockups As the industry’s positive experience with virtual simulations expands, physical mockups can be phased out.
