(010.001.A.01) 15. IDENTIFY the back panels associated with the RPS System. (010.001.A.06) 16. Given a loss of an RIPS Bus, DESCRIBE the effects on the following Systems:: (010.002.A.01, 200.102.A.01) a. RPS b. Primary Containment Isolation C. SBGT d. Secondary IIVAC 17. Given a list of statements, IDENTIFY the steps necessary to align alternate pD--wer from Essential Bus "A" or "B" to RPS Bus "A" or "B." (010.025.A.02) REACTOR PROTECTION SYSTEM 4 exceeds its sate level, the Reactor must Fig 01 B. When one of the critical parameters be scrammed. The RPS sends controlling signals -to the Control Rod Drive system to cause the actual insertion of control rods. The RPS is composed of two independent trip system-ns, "A" and "B." is initiated by the RF'S, the outlet scram valve Fig 02 C. When a Reactor scram signal (Fl 27) opens to vent the area above the piston to tihe scram discharge header and the inlet scram valve (F126) opens to admit pressure from the scram accumulator to the area below the CRD drive piston. The large differential pressure applied to the drive p:iston produces a large upward force on the index tube and control rod, inserting the rod into the Reactor. D. In order to scram the control rods, the scram pilot solenoid valves Fl 17 in trip system "A" and the Fl 18 valves in trip systenra "B" must both swap to the vent position (de-energize to vent). 1. Instrument air flows through all the scram pLlot air solenoid valves (137 each). In the non-scram condition, both scram pilot solenoid valves are energized, and instrument air holc3s the inlet and outlet scram valves closed. RPS trip system "A" supplies power to the Fl 317 valves, while RPS trip system "B" supplies power to the Fl 18 valves.. 2. Instrument air also normally flows through ttae backup scram valves (Fl 10A and Fl 101B), test valve (F008), and cne of the two scram air header pilot valves (F009 or F040). E. If a scram setpoint is exceeded in RPS trip system "A" only (commonly referred to as a half scram), the scram pilot soleno id valves in trip system "A" (Fl 17s) de-energize, but instrument air is still applied to the scram valves through the trip system "B" scram pilot solenoid valves (F1 1 8s), and the control rods would not scram.
