​​Vendor-Independent Design Requirements for a Boiling Water (BWR)

Reactor Safety System Upgrade​

Vendor-Independent Design Requirements for a Boiling Water (BWR)  Reactor Safety System Upgrade​​​

Research attachments captured in this report include: 

•    A Plant Protection System (PPS) platform and application functional requirements baseline. The envisioned PPS design concept is a common, safety-related, replacement digital platform that implements the existing functions of first-echelon, safety-related BWR systems as applications

•    A non-safety related (NSR) platform requirements and application requirements baseline for a BWR anticipated transient without scram [ATWS] Mitigation System.  ATWS functionality as well as any necessary diverse actuation functionality to address PPS common cause failure is envisioned to be implemented using this NSR platform.

•    A License Amendment Request (LAR) Framework Document. This research provides a vendor-independent LAR Framework Document created in a format consistent with the DI&C-ISG-06, Revision 2 Alternate Review process. Informed by the functional requirements baselines, the LAR Framework Document provides notional architectures and design attributes directed toward an advanced new state.​​

The technical content of these lengthy attachments based on the Limerick Generating Station is summarized in report INL/LTD-20-58490 that also explains how they were developed.  This research product was produced by MPR Associates, Inc., in collaboration with Exelon and LWRS researchers.

Report INL/LTD-20-58490 is currently not publicly releasable. It is expected that this document will be released with a revised number in late 2020 or early 2021.​
