a) Close OH-11 and DH-l2 and deenergize the pressurizer heaters, if either OH-11 or OH-12 is open and a simulated reactor coolant system pressure which is greater than the trip setpcint(<438 psig) is apolied, b) prevent the opening of DH-ll and OH-12 when a simulated or actual reactor coolant system pressure which is greater than the trip setpoint (<438 psig) is applied.
