RPS Test And Aswers.
initiate SCRAM to prevent or limit fuel damage following abnormal transients
monitored variables exceed pre established limits
flux instrumentation becomes inoperable
manual scram is inserted by the operator
Essential AC power is lost Answer - RPS purpose
Preserve the integrity of fuel cladding
Preserve integrity of the reactor coolant systerm
minimize energy which must be absorbed following a LOCA Answer - Basis of Reactor
Scram Conditions
Alternate scram features remain viable
Loss of 1 power supply, or instrument can neither cause or prevent a SCRAM
RPS action shall go to completion
Electrical and physical separation
seismic qualed
remains operable during testing or maintenance Answer - Design basis
Access under control of OPS sup
Manual bypass contolled by Control Room Operator
when bypassed continuously annunciated in C.R Answer - Minimizing Operator Error
Ensures SCRAM goes to completion Answer - 10 second time delay
7 seconds Answer - Time for all rods in?
2 independent trip systems with 2 channels A1 A2 B1 B2
1 out of 2 twice Answer - RPS logic
Maintain voltage and frquency during input transient for 2 seconds will keep RPS
supplied for a short duration loss of power to the motor Answer - RPS MG set flywheel
inside the cabinet ( overcurrent reset)
volts adjust
voltmeter
ammeter
UF/OV/UV lights Answer - RPS MG set indications
Overload
Motor High Temp Answer - Input Breaker Trips
