At 1333, a Reactor Control Operator noted that Primary Safety Valve V1202 had indications that it was leaking past its seat. Plant procedures required reducing RCS (Reactor Coolant System) pressure in 100 psi increments until the safety reseated. This event required the plant pressure to be reduced to 200 psi below Normal Operating Pressure. Prior to commencing the depressurization, a manual reactor trip was ordered by the Unit Supervisor as discussed in the pre-evolution brief. The unit was in Mode 2 approaching criticality at the time of the trip. The unit is currently stable in Mode 3, Hot Standby. </br>The reactor trip was uncomplicated.
