Ametek Solidstate Controls (SCI) has introduced its first safety-related, Pulse-Width-Modulation (PWM)-based, UPS systems designed to meet the highly specialised and rigorous requirements of the nuclear power industry.
“The Nuclear Digital ProcessPower (NDPP) uses the same reliable microprocessor design techniques found in our field-proven Industrial PWM product families. The key difference is in the digital control and monitoring software, which have been developed specifically for safety-related applications and have undergone an intensive Verification and Validation (V&V) evaluation process to meet the exacting standards of the US Nuclear Regulatory Commission (NRC),” commented Dan Huey, SCI product manager.
SCI’s NDPP Class 1E UPS system is designed and tested in accordance with the NRC audited 10CFR50, Appendix B Software Quality Assurance program, which conforms to IEEE standard 1012-2004 Standard for Software Verification and Validation, and other NRC-endorsed standards.
“To ensure maximum security against cyber-attacks, measures were taken to develop and test software and firmware exclusively within a secure environment. During operation, the NDPP 1E UPS product line offers advanced monitoring, data capturing, and event logging capability without the need for external communication with other plant safety systems. Those design considerations were implemented to maintain safe and secure operation for nuclear safety-related applications,” added Huey.
