As nuclear power plants are reaching 50-year milestones, the aging of system components needs to be considered – including those that are part of a Solid State Protection System (SSPS).

Westinghouse has developed new printed circuit cards for use in the solid state protection system (SSPS). The replacement printed circuit cards are the same in form, fit and function as the original cards, but also address obsolescence of the Motorola High Threshold Logic (MHTL) devices, which are designed to enhance reliability and include improvements for maintenance.

Many nuclear utilities installed their post-accident monitoring instrumentation using technology from the late 1970s and early 1980s. In this rapidly changing technological environment, component obsolescence and ever increasing operations and maintenance (O&M) costs are a growing concern. To address this, Westinghouse is pleased to offer a modernized PAMS using its common qualified (Common Q™) platform.
