If the R. C. temperature is above 100 F., and the OTSG shell temperature is less than 100 F., the delta temperature be-tween R. C. temperature and shell temperature must be less U

than 50 F.

2.1.6 A minimum of 30 PSI indicated on low range pressure channels RC-3A-PT5 and RC-38-PT5 (Control Room) must be maintained after filling to assure a full R. C. System.

2.1.7 Care should be taken when removing C.R.D.M. Vent plugs, There may be residual pressure under the vent plug.

2.1.8 During venting, open the vent tool valves 1/3 turn maximum.

2.1.9 Observe temperature / pressure limits for C.R.D.M. reventing shown on Figure 1.0-22.4 on page 3 of this procedure.

i NOTE:

The 300 psig applies to venting for removal of gases.

It is acceptable to vent the control rod drive mechanism up to the pressure limit established in the control rod dirve mechanism ranual to eliminate vent valve leakage.

2.2 Administrative 2.2.1 When adding water to the R. C. System maintain flow through R. C.

Pump Seal Injection lines to prevent outleakage of reactor ccolant which may carry dirt into the seals.

2.2.2 Do not pressurize the R. C. System while motors are uncoupled from R. C. pumps.

2.2.3 Care should be taken when venting at pressure not to over-pressurize the venting system.

2.2.4 Vent according to Appendix 0, sequence for venting instrumentation lines when water level indicating on tap elevation in Appendix D.

2.2.5 Fill water boron concentration must not be less that 1800 ppm.

baron.

2.2.6 Monitor radiation levels and observe required health physics procedures when filling and venting.

2.2.7 R.C. System circulation must be maintained during filling.

2.2.8 The intent of this procedure is to fill the R.C. Systeu from a totally drained condition.

It may happen that it is necessary to fill the R.C. System from a partial drain condition.

In this case it will be necessary for the Shift Supervisor /Sup-

2.1 See main procedure (2103-1.1) secticn 2 3.0 Installation Procedure:

3.1 Inspect vent tool threads and hex head surfaces for nicks, burrs, and scratches.

Flush the tool with demineralized water.

Place a high film of Neolube on the vent tool threads.

CAUTION:

It is suggested the venting tool by hydrotested prior to the vent-ing operation (required prior to initial use) and that before an operator ese the tool at higher pressure and temperature he per-form the entire sequence of steps in accordance with this proce-I dure :o be certain that he is familiar with use of the tool.

3.2 Lubricate the vent tool-to-C.R.D.M. vent port 0-ring with an approp. iate lubricant, e.g., Dow Corning 200.

3.3 Attach a nylon lanyard to the C.R.D.M. vent plug to prevent dropping when removed.

~

3.4 Remove the C.R.D.M. vent plug ' ' the following manner:

1.

Turn the vent plug one revolution. Check for any sign of leakage or pressure beneath plug.

2.

Continue to remove plug using 1/2 turn revolutions and checking for leakage with each revolution.

This is not reouired if the R.C. System is at atmospheric pressure.

3.5" Check that the vent tool is in the disengaged position (vent cap to vent housing standoff should be approximately 5/16 inch and the vent cap is rotated fully in the counter clockwise direction.)

3.6 Check that the secondary valve is closed.

3.7 Thread the vent tool into the top of the closure insert assembly in the clockwise direction to hand tight.

3.8 Connect the vent tool to the vent header piping.

3.9 Check that the secondary valve is closed.

3.10 Place an ir.ch-pound terque wrench on the vent tool 5/16 inch hex head.

3.11 Put a slight clockwise torque (1-5 inch-pounds) on the vent tool hex stem, push the vent cap down, and turn the vent cap clockwise to a hard stop while engaging the vent valve hex stem (lower portion of stem) with the female hex on the C.R.D.M.

CAUTION: Always keep a slight c'.ockwise torque (1-5 inch-pounds) on the tool stem during this step.

3.12 Turn the lock screw (knurled end) clockwise until it bottoms out.

3.13 The vent tool is now ready for operation.

4.0 Venting

4.1 Turr tool stem approximately 1/4 to 1/2 turn counter clockwise to crack open the vent valve.

CAUTION: Do not allow vent housing to rotate during this operation.

4.2 Open secondary valve aporoximately 1/8 turn or less to obtain proper 1

4 throttling of gas / liquid. When the R.C. System is at atmospheric pressure, this valve may be opened further.

4.3 Vent until water appears using a gauge glass or other suitable device for visual observation.

5.0 Removal Procedure:

5.1 Close the secondary valve.

5.2 Check to see if there is any leakage past the secondary valve.

5.3 Torque the vent tool stem to 50 - 60 inch-pounds in the clockwise direction.

5.4 Turn the lock screw (knurled end) counter clockwise until it is free.

CAUTION:

Do not allow the vent housing to turn in the counter clockwise direction during this step.

5.5 Disengage the vent tool cap while maintaining 50 - 60 inch-pounds torque on the vent tool stem in the clockwise direction.

Disengage the vent tool cap by rctating it to a hard stop on the counter clockwise direction.

fiOTE:

Vent tool stem and vent tool cap will raise approximately 5/16 inch at the hard stop.

5.6 Rotate the vent tool stem clockwise to ensure that the tool stem is free from vent valve (stem should rotate freely).

5.7 Open the secondary valve to relieve pressure from the vent tool.

5.8 Close the secondary valve.

5.9 Disconnect vent header piping described in Steo 3.8.

Do not permit vent housing to rotate during this step.

5.10 Open the secondary valve.

If water appears close the valve and repeat Steps 3.8 through 5.10 o' this enclosure.

If torquing the vent tool stem to 60 inch-pounds does not seat the vent valve, notify the shift supervisor who will evaluate the leakage with whatever assistance and guidance from the supervisory staff is necessary.

If the shift supervisor deteryi%

additional torque is necessary to stop the leakage, t.he torque shall be applied in 5 inch-pound increments until the leakage ceases or a maximum of 100 inch-pounds is reached.

If leakage continues at the

,naximum torque val;e of 100 inch-pounds, it is imoerative that the Station / Unit Superintendent be notified. The vent plug may then be installed as described in steps 5.10 through 5.15 and torqued to 15 foo t-pounds.

5.11 Rotate vent tool counter clockwise to remove from C.R.D.M.

5.12 Aspirate any water from the top of the C.R.D.M. closure insert.

5.13 Check C.R.D.M. vent plug for nicks, burrs, etc., repair if required.

Place a light film of Neolube on the vent plug threads.

5.14 Obtain a new vent plug 0-ring cnd lubricate it with an appropriate lubricant as in Step 3.2 of this enclosure.

Place new 0-rii a on C.R.D.M. vent plug.

Install the vent plug, and torque 5.15 5-10 foot-pounds. After final torquing is complete, make a visual ic:?ec-tion of vent plug to ensure no extrusion of 0-ring exists.

If extrusion exists, the 0-ring must be replaced and step 5.15 repeated.

NOTE:

The vent tool cap should be torqued immediately after aspirating water from the top of the assembly.

If the cap is torqued after water collects in the closure assembly, the "0"-ring will be damaged.

5.16 Repeat procedure for each C.R.D.M.

APPENDIX D (cont.)

Bailey type BY transmitters are constructed so that all the air cannot be vented from the capsule chambers by normal venting orocedures. On pressurized systems with the low pressure side not vented to atmosphere, this can cause erroneous readings and possible transmitter damage during transients which cause large differential pressure changes (such as shifting pumps). To remove the air from transmitters installed in such systems, it is necessary to drive the air into solution under pressure end then vent the air-water. mixture at the elevated pressure until all the air is purged from the cell.

If the system is not pressurizcd and the low pressure side is vented to atmosphere, Steps 1-19 below are not requi red.

4.1 Procedure 1.

Connect the BY transmitter as shown in Figure 1.

Manipulate the plastic tubing to dislodge any air bubbles after filling reservoirs.

2.

Open valves V1 V2, V3, V6, and V7. Shut valves V4 and V5.

3.

Pump water from the pump into the transmitter.

4.

When water flows from the high pressure vent, shut V1 while continuing to pump water. When water flows from the low pressure vent V2, shut V2 while cuntinuing to pump water to insure no air is trapped inside the capsule.

5.

With both reservoirs vented to atmosphere, open V4 and V5 and shut V6.

Pump water from the pump until air stops flowing into the plastic turbine.

Shut V7 and manipulate the plastic tubing to dislodge the

_5,j air bubbles and cause them to rise into the reservoir.

6.

Repeat Step 5 for V6; Shut V4 and V5.

I?O 5

12/27/77 i

7.

Open '!6 and V7. Pump water until the pressure reaches 0900-1100 psi and hold this pressure for 3 to 5 minutes.

8.

Open the flow pressure vent V2.

Pump water to maintain a vigorous flow until the vented fluid is clear.

The aischarge from the vnt will appear white in color due to small air bubbles as the air comes out of solution at atmospheric pressure. When the discharge is clear, all air is removed from the low side.

9.

Rep %t Step 7 and 8 for the high pressure vent V1.

10.

Repeat Steps 7, 8, and 9 until the discharge water is completely clear.

11.

Shut V6 and V7.

12.

Slowly crack V4 and allow air to be relieved to the reservoir.

13. Fully open V4 and V5.

If all the air is out nf the cell, the levels in the two reservoirs will eq.. lize.

14. Calibrate and perform static zero pressure correction if required.

15.

Shut V4 and V5.

16.

If working on a pressurizer level DP cell, fill the reference leg if necessary per Section 1.2.la, b, & c pumping water through V7 oer Figure 2.

17.

Remove test hookup.

18.

If working on a DP ce'

' sed for flow measurements, fill the impulse lines of the cell frorc. the system by opening first the root valvas, then the manifold stop valves and flush the lines clear of air bubbles through the test ties, one line at a time.

20. Place the cell in service as below:

a).

Check the manifold stop valves shut.

Check open the equalizer valve V3 and external equalizer valve if installed.

b).

Crack, then fully open the high pressure manifold valve.

c).

Shut V3 and the external equalizer valve if installed.

d). Open the low pressure manifold valve.

5.

Operating Bailey Type BY Transmitters Not Previously Dry If a BY transmitter does not have a dry range capsule as it would following capsule maintenance or prior to initial R.C. System fill, air will not be trapped in the capsule and the pressurized venting procedure of 4.1 will not be required.

Vent the impulse lines as in Section 5.1 below.

5.1 Procedure 1.

Check shut the manifold stop valves.

2.
