Today’s nuclear power plant operators want safety-related systems that work for multiple decades without major upgrades. Previous generation digital I&C systems required frequent firmware updates and proved difficult to manage under current cybersecurity and regulatory constraints.

The SER-approved HIPS FPGA was designed with you in mind. It doesn’t attempt to push the boundaries of modern technology. It won't do your taxes, but it also won't raise eyebrows from upper management nor the NRC. It simply performs with robust, analog-like reliability while providing essential diagnostics for plants to reduce O&M costs.

Reactor Protection System Architecture
The scalable HIPS platform has complete architecture flexibility. It can be configured as a single channel or up to a full RPS of four separation groups which votes into two divisions complete with physical and electrical isolation.

Model-Based Design
Model-Based Design provides a significant increase in the quality of the final product and reduction of project execution costs.

It’s an all-in-one environment to meet the rigorous development requirements for safety critical systems in a significantly reduced development time by integrating both the system’s functional behavior and the detailed description in one project model.HIPS Model-Based Design automates error prone and time-consuming tasks, reducing the development time associated with code and document generation, test execution, and model checks.

Additionally, simulation of the system behavior provides the ability to examine its interaction with individual components to detect errors in requirements and design early in the development lifecycle before testing on expensive hardware.

Class-1E SER Approval
The HIPS platform topical report TR-1015-18653-P, Revision 0, “Design of the Highly Integrated Protection System [HIPS] Platform” was submitted in 2015 in partnership with NuScale. Rev. 1 was submitted in 2016 with NRC SER approval granted in 2017.

Software Common Cause Failures (CCF) Mitigated by Internal Diversity
The diversity in our FPGA equipment, circuit designs, and software tools are the fundamental methods for mitigating the potential for digital CCFs in the HIPS platform. The platform design uses two diverse FPGA technologies to achieve equipment diversity: one is a one-time programmable (OTP) or flash-based FPGA, with the other static random-access memory (SRAM) based FPGA.

The overall HIPS diversity approach aligns with NRC BTP 7-19 and provides additional benefits by simplifying the holistic I&C facility design, since a separate diverse actuation system is not required to mitigate digital CCFs.

The diversity approach also provides analytical and regulatory review benefits, since additional 'best estimate' consequence analysis is not required. This ensures a more efficient regulatory turnaround and quicker system build for a higher level of confidence in meeting your project deadlines.

Additional Specs
• Triple modular redundant (TMR) data processing, regardless of system scale
