40-2 CONSTRUCTION SPECIFICATIONS FOR PRESSURIZER RELIEF VALVE POSITION INDICATION SYSTEM AT PALISADES NUCLEAR PLANT
- 1. 0 GENERAL The Valve Position Indication System to be installed to monitor the pressurizer relief valves at Palisades Nuclear Plant is a Babcock and Wilcox Valve Monitoring System.
The system functions by *measuring fl ow noise in each valve and converting the signals to meaningful outputs, specifically, visual indication, audio monitoring, audible al ann annunciation, and visual alann annunciation.
A piezoelectric accelerometer is to be mounted on each of five pressurizer relief valves.
This device produces an electric charge pro port ion al to the noise caused by fluid flowing through the valve.
Each accelerorreter is connected, via special coaxial cable, to one of five charge amplifiers mounted outside the pressurizer room.. The charge amplifier converts the coulomb charge signal to a voltage.
This 0 to 10 volt signal is conducted through a shielded~ twisted pair cable to the panel-mounted signal conditioner and monitor/alann unit.
The signal conditioners and monitor/al ann unit are to be 1 ocated. in the plant control room.
Each signal conditioner provides power to a remotely-1 ocated charge amplifier; filters and conditions the incaning voltage signal for the roonitor/alann unit; displays the signal level on a rreter which is part of the signal conditioner; provides an al ann signal to the monitor/alarm unit; and indicates alann condition on the signal conditioner panel front.
A common monitor/al arm unit serves all five signal conditioners.
It provides a canroon alann bus with audible annunciator and retransmitting contact output.
The dual monitor section allows the operator to select any of the five channels for *audio rronitoring.

Figure 2-1 depicts the required mounting surface to be prepared on the outlet flange of valves PRV-10428 and PRV-10438.
Figure 2-2 shows the same for valves RV-1039, RV-1040, and RV-1041.
The mounting locations shown on Drawing 9418 are only suggested locations; the transducer may be mounted at any of a number of points on the circumference of the flange.
The only requirement is that the transducer be installed in the center of the region betineen two bolt holes.
To machine the flange of a valve in place on the pressurizer will require a magnetic base electric drill, a center-cutting end mill, and several clamps, plates, and brackets to support the drill.
The drill is to be set up over the area to be machined.
With the end mill in the drill chuck, start the dril 1 and 1 ower the mil 1 until it just contacts the flange.
Continue to feed the mil 1 into the flange Lmt i1 the outer edges of the mill are about to enter the work.
If a 7 /8-inch diameter center-cutting end mill is used, the machined area should now be sufficient to mount the transducer.
Without moving the drill base, retract the drill motor and mill, and stop the motor.
Remove the *mill arid install a #21 drill.
Drill a hole in the center of the machined area to a depth of 3/8 inch.
This hole must be drilled within +/-6 minutes of perpendicular with the machined surface.
Tap 110-32 threads using the plug tap to start and the bottom tap to finish the task.

40-2 For the safety relief vaives, RV-1039, RV-1040, and RV-1041, it is sug-gested that the surface be machined and the mounting hole drilled and tapped before the va*1 ves are re-insta.1 led on the pressurizer.
The machinist should remove material to* provide a surface in accordance with Drawing 9418.
Having milled a flat surface on the flange, the machinist should drill and tap a #10-32 hole in the center of the machined area.
Transducer mounting requires that this hole be 3/8-inch deep, and not more than !6 minutes off perpendicular with the machined surface.
2.5 Transducer Installation Do not install the transducer until the valve is in place in the pres-surizer piping system.
Screw the mounting stud, Endevco No. 2981-3, into the fl0-32 hole in the flange.
Tighten with a screw driver.
Apply the Pryogel acoustical coupling canpound to the base of the transducer, and twist the transducer onto the stud by hand.
Tighten the transducer with a Del rin socket and torque wrench to a torque of 18 inch-pounds.

40-2 ihe hardline and softline cables are to be connected together prior to installation in their respective conduits.
One end connector of each cable is screwed onto the EJ34 connector.
.Before proceeding with sealing the connection, the resistance of the spliced cable should be tested with an ohm meter.
If the total cab 1 e resistance exceeds 18 ohms, then the con-nect ion should be checked by disconnecting one cable and testing the resi s~
tance from one end through the EJ34 connector.
Check the other cable in the same fashion, an~r disconnecting th~ tested cable fran the connector and reconnecting the remaining one.
if the resistance of a cable piece and connector is too high, check the cable piece alone.
If it checks
- properly, substitute another EJ34 connector and* recheck.
If any cable or connector fails to check out properly, then it must be replaced with a new item fr-an the vendor.
When the resistance checks -are completed, then the connection may be seal ed.
If the plant requires that connectors be secured with. safety wire, it should be installed prior to sealing.
Sealing is accomplished by first wrapping the connection with Scotch Z3 electrical tape and then overwrapping with Scotch 33+ vinyl plastic tape.
The Scotch 23 base tape is applied with moderate tension, beginning at the splice and 1/2 lapping to a point 2 inches back on the cable.
Take one full lap turn, and then 1/2 lap back across the splice to a point 2 inches on the other side of the splice.
Full 1 ap one turn, then 1/2 -1 ap back to the* splice.

Lay the cables in the trays back to the vicinity of the charge ampli*
fiers.
Insert the cables into the 1-1/4-inch conduit.to the junction box.
Spread the cables and route each to its respective charge ampli-fier.
Cut the excess length from the cable, and remove two inches of the sheath.
Strip the leads 1/4 inch, and install ring tenninals using a plant-approved crimping tool.
Be sure to put a tenninal on the shield drain wire.
Tenni nate the three conductors as follows:
Black - S (signal - corresponds to the center conductor of coax)
White - C (common)
Drain - Sh (shield)
Refer to schematic Drawing 9419 for connections of cables i.n the charge amplifiers and at the contairunent electrical penetration.
After the cables are laid i.n the cable trays, they must be secured using cable ties spaced not more than 18 inches apart on vertical runs and not more than 48 inches apart on horizontal runs.
Cables and conductors are to be identified with pennanent mar!<ers on each end in accordance with plant practice.
Seal the fl ex conduits between the charge amplifiers and junction box with Dow-Corning RTV Silicone at the charge amplifier ends.
