Streamlining the regulatory process to enable the industry adoption of digital technologies has taken decades. PSEG tackled this challenge with the replacement of obsolete uninterruptable power supplies (UPS) with state‑of-the-art digital designs in safety-related applications across all three of its nuclear units. The new AMETEK-Solidstate Controls (AMETEK-SCI)-designed digital processing UPS inverters are part of a multi-unit project to address legacy Cyberex analog units. This is the first application in the nuclear fleet for this design in safety-related systems in both PWR and BWR units and first implementation using NRC’s 10 CFR 50.59 process.
