This allows automatic opening of that Unit's two power relief valves at d435 psig for low temperature overpressure protection (LTOP) of the reactor vessel. This safeguard circuit ensures that the reactor pressure remains below the ASME Section III, Appendix G "Protection against Non-ductile Failure" limits in the case of an LTOP event.
