What is True or false. The purpose of the flow injection system is to minimize the ingress of radioactive crud from the fuel channels into the fuelling machines

What is The connector actuator has driven down to the mechanical limit.

What is the way to minimize of radioactive crud from the fuel channels to the fuelling machines is achieved by:
a) Supplying clean reactor grade D2O to the fuelling machines during fuelling to produce a net inflow of D2O into the fuel channel. The flow of D2O washes crud, being carried by the shield plug and fuel, back into the channel. It also prevents ingress into the fuelling machine of hot reactor D2O which is also a crud carrier.
b) Ensuring the fuel has been cleaned at the New Fuel Loading Mechanism before loading it.
c) Supplying clean D2O from the D2O storage tank to the fuelling machines during fuelling to produce a net inflow of D2O into the fuel channel. The flow of D2O washes crud, being carried by the shield plug and fuel, back into the channel. It also prevents ingress into the fuelling machine of hot reactor D2O which is also a crud carrier
d) The snout filter.

What is true or false? CONNECTOR ACTUATOR A ABNORMAL DOWN (CONNECTOR ACTUATOR B ABNORMAL DOWN) light is lit it indicates that the actuator is in the abnormal down position

What is the switch that detects when adequate force exists between the mobile half and the fixed half of the remote connector which ensures a satisfactory seal, when driving the connector up.

Connector Actuator Mated indicates that the thrust in the Up direction is adequate for a _____ and the connectors are ______ and the mobile connector has been driven up high enough to __________ to the fixed connector.

When is Connector Actuator A Up Torque Limit light lit?

What is the purpose of the Connector Actuator Down Torque Limit switch, ZS1T-CAD/ZS1T-CBD is to:
