The PNPS simulator currently runs on SGI computers with the IRIX operating system, and once upgraded, its servers and instructor station will operate on PCs running the Windows operating system and L-3 MAPPS’ Orchid simulation environment.

In addition to maintaining communications with the simulator’s existing input/output (I/O) system, a latest-technology expansion I/O system will be added by L-3 MAPPS, which will operate concurrently with the existing I/O system using Orchid Input Output.

The upgraded simulator is scheduled to commence operation in the summer of 2012.

The power station is currently equipped with multiple classroom simulators which will be migrated to the new environment.

An additional classroom simulator will be provided based on L-3’s Orchid Touch Interface technology.

The three-bay classroom simulator uses large touch screen monitors with 1080p full HD resolution to display near life-size operable virtual control room panels, the company said.

Under the contract, Entergy Nuclear has also an option to upgrade the PNPS simulator’s reactor core model with Orchid Core Builder.

Located in the US state of Massachusetts, the Pilgrim nuclear power station has a generating capacity of 684MW.
