In addition, the synchronous acyclic homologically trioial joint test of the back seat position that the hollow piston in the control rod drive mechanisms (CRD) 12 of actuator 7 and the connection of control rod are disengaged, be to regulate at the state that control rod is positioned at back seat, make control rod position counting value and back seat position consistency on the control rod position signalling treatment circuit of central control unit 1 or on-site control device 3, show what carried out the back seat position by the control position that shows on the control rod operation panel of confirming central control unit 1.
Promptly, hollow pistons in the control rod drive mechanisms (CRD) 12 are connecting (バ イ オ カ Star プ リ Application グ) when the position is the back seat position with living of connecting of control rod, the consistent operation of count value of the demonstration control rod position that the control rod position of implementing to make actuator 7 expressions and central control unit 1 or on-site control device 3 are interior.At this moment, as shown in figure 12, be arranged on the adjusting of the synchronous digital signal transformation component 70 in the unit of on-site control device 3, the count value of confirming the control rod position in the on-site control device 3 shows the back seat position, and the control rod position display back seat position that shows on the control operation plate of affirmation central control unit 1.
Like this, in the back seat position, the count value of the expression control rod position in the control rod position by making actuator 7 expression and central control unit 1 or the on-site control device 3 is consistent, and central control unit 1 and on-site control device 3 can be formed for carrying out the A-stage that control rod is controlled.
Figure 13 is that a machine identical with the actuator structure replaces an actuator, is connected the connecting line line end of actuator,, the key diagram when carrying out the action test of the action test of actuator and central control unit, on-site control device.
Among Figure 13, the machine 71 identical with the actuator structure is connected the connecting line line end 63 of actuator 7.Implement the simulated action of the actuator 7 that the steering order of central control unit 1 and on-site control device 3 outputs causes and confirm, and implement central control unit 1 that the action of actuator causes and the interlocking of on-site control device 3 is confirmed.Like this, by adopting and the identical machine 71 of actuator 7 structures, even when not having the action of actuator 7, also can be to central control unit 1 and on-site control device 3, the action that simulation and actuator 7 are same.
Here, to the machine 71 identical with actuator structure, also can implement with actuator 7 same load condition is arranged the time the action test.At this moment,, adopt and the identical machine 71 of actuator 7 structures, make the action simulation signal exported from the machine 71 identical more near the action of real machine with the actuator structure as much as possible with the condition close with the service condition of actuator 7.
In addition, when the interlocking of the confirming operation of the actuator 7 that causes in the steering order of the central control unit 1 of implementing control rod operation supervise and control system and on-site control device 3 outputs and central control unit 1 that is caused by the action of actuator and on-site control device 3 sides is confirmed, also they all can be coupled together and carry out.That is, central control unit 1, on-site control device 3, actuator 7, sensor 8 are all combined, make actuator 7 actions.Like this, implement the confirming operation of the actuator 7 that the steering order of central control unit 1 output causes and the central control unit 1 that causes by actuator 7 actions and the interlocking of on-site control device 3 and confirm, implement the repertoire of control rod operation supervise and control system with the real machine action and confirm.
Figure 14 is the key diagram with the action test of the control rod position detector 15 of control rod position indication (PIP) input control rod position of switching signal.
With the control rod position detector 15 of the control rod position of switching signal indication (PIP) input control rod position, be to make contact 73ON/OFF by the magnetic force that is installed in the magnet 72 on the control rod 6, detect the control rod position.On this control rod position detector 15, connecting measuring device 44 and instrumentation control device 74.Instrumentation control device 74 is according to the ON/OFF of contact 73, instrumentation control rod driving time.
The ON/OFF time of the control rod position signalling on the instrumentation data that measuring device 44 instrumentations are measured when control rod drives, according to the number of the contact 73 of control rod position detector 15 and being provided with at interval of each contact 73, the detection time of obtaining the control rod position signalling that each contact 73 causes is t at interval.Like this, confirm the operating state of the contact 73 of control rod position detector 15.Measure the detection voltage V of control rod position signalling again, confirm that the decline from rated voltage of this detection voltage V is in the scope that does not influence the instrumentation control device.Like this, the viability of carrying out the control rod position detector is confirmed.
In addition, being used to detect the contact 73 of control rod position, is ON during its magnetic force F 〉=F1, is OFF during F＜F1.Here, F1 is the required power of contact action.In control rod position detector 15,, only when magnet 72 and contact 73 same positions,, when stagger in the position, make contact 73OFF at once because F 〉=F1 makes contact ON in the control rod direction of action.
The electric charge of supposing to be installed in the magnet 72 on the control rod is Q1, and the electric charge of each contact 73 is Q2, and the distance that each contact 73 and magnet are 72 is r, and power F can represent with following functional expression.
F＝(1/4πε0)·H(Q1)·K(Q2)·G(r)
Therefore, inappropriate when the magnetic force of magnet 72 docking points 73, when measuring device 44 can not detect the regular event of contact 73, promptly contact is failure to actuate, ON time of contact or OFF time is when too short, and magnetic force F is adjusted to suitable value.This adjusting is by regulating carrying out apart from r of 72 of contact 73 and magnet.
That is, the contact 73 of control rod position detector 15 is connected on the measuring device 44, the counting certificate during from actual drive controlling rod detects ON/OFF time of each contact 73.The contact 73 as each pulse emissive source on the instrumentation data is inferred at the control rod speed during from instrumentation and the interval of each contact 73, verifies whether the ON/OFF time of each contact 73 is up to specification.When against regulation, regulate 72 of each contact 73 and magnet apart from r, carry out the ON/OFF time verifying of contact 73 once more.
In addition, from the ON/OFF time of the contact 73 that detects the control rod position, at the driving time (with the scram time) of instrumentation control device 74 instrumentation control rods 6.Before control rod position signalling (simulation) input instrumentation control device 74 from control rod position detecting circuit 14, to ON/OFF time of the control rod position signalling on the instrumentation data of measuring by measuring device 44 with as the instrumentation result's of instrumentation control device 74 control rod driving time, carry out the time data contrast, confirm the instrumentation function of instrumentation control device 74.
