> Digital Upgrades for Nuclear Plants

Hurst Technologies is on the front wave of activity in retrofitting nuclear plant control systems with digital technology. The latest example is the replacement of the annunciator, plant process computer (PPC), and simulator at an upper Midwest nuclear plant. HTC functions as the owner’s engineer.

When the project is completed, scheduled for mid-2014, plant operators will use 23 video display unit (VDU) touch screens that will take the place of the old analog-based annunciator board in the control room. According to the project engineers, the technology employed is unique – it hasn’t even found its way into fossil plants. read more
