RBM operability is required in the run mode in the presence of a limiting rod pattern with reactor power greater than the RBM low power setpoint (LPSP). A limiting rod pattern exists when:
MCPR < 1.41 for reactor power > 90%
MCPR < 1.72 for reactor power < 90%
The allowable value for the LPSP is < 25.9% of rated core thermal power.
