Glass Panel MCR Simulator (GPMS) 15
Glass Panel MCR Simulator (GPMS)
- Originally intended to solely offload certain Ops training from the plant reference Simulator
- Needed to permit extensive hardware changes
- Usage has evolved
- Recently completed the SPS Conceptual Validation workshops on the GPMS
- Also intending to use for Preliminary Validation and possibly Integrated System Validation
- 2nd Plant Reference Simulator also planned 16
