6.1-5 Revision 0 SUBJECT TO DOE COOPERATIVE AGREEMENT NO. DE-NE0009040 Copyright © 2025 Long Mott Energy, LLC All Rights Reserved Long Mott Generating Station Preliminary Safety Analysis Report When a non-safety-related SSC is required to protect the SR SSCs in their ability to perform their RSFs, such non-safety-related SSCs are not necessarily NSRST. The NSRST classifications are based on the Probabilistic Risk Assessment (PRA) Safety Functions (PSFs) these SSCs perform to prevent or mitigate event sequences and not functions that are focused on protecting the SR SSCs.
Table 6.1-3 provides the non-safety related SSCs that have design requirements to protect the SR SSCs performing their RSFs in response to DBHL.
