A protection system for a BWR may include a power-dependent high reactor pressure setpoint. The high reactor pressure setpoint that corresponds to at least one value of percent power in an operating domain of the reactor may be less than the high reactor pressure setpoint that corresponds to 100% power. A method of operating the BWR may include implementing the power-dependent high reactor pressure setpoint. The protection system may include a first high reactor pressure setpoint that corresponds to 100% power and at least one second high reactor pressure setpoint that corresponds to one or more values of percent power in the operating domain. The at least one second high reactor pressure setpoint may be less than the first high reactor pressure setpoint. The method of operating may include implementing the first high reactor pressure setpoint and the at least one second high reactor pressure setpoint.
