1.1 IHl3 INSTRUCTION COVERS THE SYMPTOMS, AUTOMATIC ACTIONS AND MANUAL ACTIONS FOR A STEAM 6ENERATOR TURE LEAK AND A STEAM GENERATOR TURE RUPTURE. EITHER OF THESE CONDITIONS RESULT IN LEAKAGE OF REACT 0F COOLANT INTO THE SECONDARY SYSTEM.
1.2 OPERATOR ACTION 15 REQUIRED, IN ACCORDANCE WITH THE ACCIDENT ANALYS!$ IN THE FSAR, IN ORDER TO IDENTIFY AND ISOLATE THE FAULTED STEAM GENERATOR ON A TURE AUPTURE. REACTOR COOLANT SYSTEM PRES $URE MUST BE REDUCED TO LESS THAN 1000 PSI WITHIN 30 MINUTES IN ORDER TO PREVENT LIFTING OF THE STEAM GENERATER SAFETIES AND POWER OPERATED RELIEF VALVE ON TnE AFFECTED STEAM 6ENER' TOR.
