Tbc material (s) that you are responsible for is/are stated in the objectives for this lessoa. TP-1 2.0 PRESENTATION A. Symptoms that indicate entrance into this abnormal Obj. #1 procedure.
- 1. The following ant.unciator Alarms
- a. Station Air CMPSR Trcuble i
- b. Instrument Air Eng. CMPSR Trouble
- c. Air Faader Pressure Low (1) Station 97 psig (decreasing) 7 (2) Instrument 95 psig (decreasing) i
- 2. loss of Instrument Air is defined as < 75 psig on Inst, Air Header pressure indicator PI810 (located in the Control Room.
- a. Atthispressuref>)5psig),theoperatorwill experience a loss of
(1) Velve Control Enclosure 2 of AB 1
(2) Indicators Enclosure 1 of AB (3) Alarms Enclosure 1 of AB B. Operator Actions i 1. The operators first action (s) is to follow the OBJ #3 and 7 appropriate alarm procedure (s),
(i.e.) a, Start Additional Compressors
- b. Correct the cause i
- 3 of 11
A LOSS OF INSThuMaNT AIR AB 1203.36 GOP-OLC.001.01 Attachment 36
- 2. The operators second action is to perform the Details of Actions Actions listed in the applicable procedure are given in the AB when the initiating condition (s) is/are met,
- a. PI 810 g 75 psig (1) Trip the Reactor (2) Actuate SFRCS on Low Steam Generator Level i
(3) Perform EP 1202.01, RPS, SFAS, SFRCS Trip or SG Tube Rupture.
a (4) Continue to correct the cause.
(5) Insure Station Air Header is isolated SA 2008. TP-2 (6) Insure Filter / Dryer Emergency Bypass Line Regulator and Filter are in service.
(7) Isolate the normal inst. air filters and dryers.
- 3. When header pressure decreases to 70 psig insure that the following header (s) is/are isolated.
- a. Turbine Building
- b. Water Treatment Building
- c. Perform the following actions (1) Trip both heater drain pumps '
(2) Shutdown the screen wash pumps (3) Shutdown the cooling tower makeup pumps (4) Open condenser vacuum breakers (5) Lockout the mechanical hogger (6) Shutdown the steam packing exhausters (7) Try to maintain one condensate pump running 4 of 11

- 10. Atmospheric Vent Valves
{ Fail Position - Closed
$ Location - In the radwaste ventilation area outside the Control Room (elevation 623') is located a manual handwheel and two valves for i each atmospheric vent valve. Instructions are posted near each handwheel as follows:
Manual Operation - Close Valve A (see drawing) SL-12 which isolates air from Valve V3.
Open Valve B (vent valve) which vents actuator air through V3 Check the handwheel counter at zero. Then open SL-13 the handhweel (CCW) to the desired position.
0 turns = closed
, 253 turns = open J
l NOTE: Valve does not start to open until approx.
13 turns.
If partial closing is desired, simply rotate the manual handwheel in the clockwise direction since the valve is spring assisted in the close direction.
If positive shutoff is desired, close the manual handwheel until it reaches the full closed position j (zero counts on counter).
Close B Valve CAUTION: Do NOT open A valve unless remote manual operator counter is at zero counts as damage can occur to the lifting fork on the valve stem.
Open A valve to restore closing air to the actuator.

- 11. Discuss the process to return the hand jacked valves to auto.
- a. Basically go in reverse orcer of placing valves in manual. Emphasize that: Keys must be removed from keyways and hand jacks returned to the " neutral" position (if applicable) 3.0
SUMMARY
A. Review symptoms 4
B. Review initiating event f"
C. Review initial plant condition D. Review final plant condition E. Review Emergency Action Level the site may be in.
OPTION: At the instructors discretion - use TP's of TP's included Systems to indicate valves that will not control ~or fail.
