(2) The condensate system is operating normally per OP-1106-2.

(3) The feed system is being controlled automatically from ICS-13 Steam-gen reactor master M.C.S.

(4) Feedwater chemistry is in specs, set forth in Plant Chemistry Manual.

3.3.2.2 Nor=al System Operating Procedure Normal operation utilizes both main feed pumps FW-PlA & B, using 6th stage steam from the outlets of moisture separators 4 and 6 to drive the turbines for each pump. Each turbine speed is adjust-able for pump flow up to 16,100 gpm, about 7,050,000 lb/br. The feedwater flow is controlled through the use of control valves while the Zip across these valves is maintained constant thru the variable speed feed pumps. The pressure drop across the valves is monitored and compared to an adjustable setpoint. The error signal thru pro-portional, plus integral action, controls the feed pump turbine speed. The feed pumps discharge to the H.P. heater strings A & B.

Each heater string consists of two (2) H.P. heaters, the 2nd and 4th sttge. The feed water- temperature is increased to about 460 F.

prior to entering the steam generators. The feed pumps are pro-tected during low flow condition by recirculation lines to the main condenser. Water chemistri .';ocural and treatment is provided on the condensate syste- by: ~,.ere are sampling provisions on the header just prior to the ' ed watsr flow control valves and on the cleanup recycle line to the main condenser.

3.3.3 Normal System Shutdown 3.3.3.1 Prerequisites for Shutdown

1. The system is operating as per Section 3.3.2 Normal Operation.

3.3.3.2 Shutdown Procedure (Indicate satisfactory completion of steps below by initialing each step and sign name at end of applicable section). Shutdown of the feedwater system is performed in conjunction with the condensate system, realizing that due 'to interlocks a main feedwater pump is shutdown before a condensate 17.0

1106-3 Revision 13 07/18/79 booster pump. The first feedwater pump will be removed from service when the total feed flow is within the capacity of one pump. A main feedwater pump will be utilized to remove excess or decay heat from the primary systtaa after shutdown by feeding the steam generators and dumping steam to the main condenser.

This process is continued for primary system cooldown by dragging the steam pressure as low as possible and then switching to the decay heat removal system. When secondary system pressure is reduced sufficiently to remove the main feed pump from service, adequate feedwater pressure will be provided by the condensate and booster pumps at the stage of cooldown.

1. As plant load is reduced to 15% by the ICS, check operation of recirc. valves FW-V7A & B, indication on console C.L.
2. Place ICS-36B(A)-MSC, FPT-B(A) speed control, in hand and

, reduce to minimum speed. (Feed pumps are placed in hand as plant conditions permit.)

1. The feed system is operating normally per Section 3.3.2 of this procedure.

3.4.2 Procedure Either H.P. heater string may be bypassed for maintenance and plant operation at rated power continued. This procedure is for routine heater removal for maintenance and not intended to be used as an emergency procedure. Care must be used when isolating a heater string to insure that all drains, vents, and extraction steam lines have been isolated from the heaters being taken out of service. Extraction steam supply to heaters will be secured first. After the H.P. heater string being isolated has cooled down, feed water flow can be stopped by closing the H.P. heater inlet valve FW-V-2A(B) and simultaneously opening teh H.P. heater by-pass valve FW-V4. Monitor feed water header pressure P.I.-32 on computer while opening FW-V4 and maintain pressure at approximately the same value prior to isolating heater string. During this operation monitor primary systems parameters as changes in temperature and power can be expected due to cooler feedwater entering the steam generators.

When heaters are returned to service, feed water flow will be extablished first and extraction steam last. This procedure covers the feed water section of the system, tube side of the H.P. heaters. For detailed operation of vents, drains, and extraction steam, refer to appropriate operating procedure.

a. Oil tenperatures normal.
b. Oil pressures normal.
c. Vacuum trip reset.
d. Low pressure steam available up to the L.P. stop valves.
2. Reset the turbine locally by pulling on the reset handle.
3. Roll the Unit to approximately 2000 RPM using the handwheel on the motor speed changer.
4. Continue increasing speed, in approximately 50 RPM incre-ments, until no further speed increase results. This speed corresponds to the low speed stop setting of the air motor. Record this value on the data sheet.
5. Continue turning the handwheel until it reaches its physical stop (MSC - high speed stop).
6. Using the feed pump speed controller at the Control Room Operator's panel, increase turbine speed to approximately 5400 RPM.
7. Perform an "Overspeed Trip Test" from the panel on the turbine. Record results on the data sheet.

NOTE: If this test is not successfully completed, no attempt is to be made to overspeed the unit.

8. Verify action of the Backup Overspeed Device as follows:
a. Energize the " Lockout Valve" as performed in step (7).

33.0 I 1135 187  !

4

1105-3 Revision 13 07/18/79 NOTE: The lockout handle must be held in the

" locked out" position throughout the entire bhckup overspeed check. If this test is not successful, it is permissabic to overspeed the turbine, but the Backup Overspeed Device must be adjusted.

b. Continue increasing speed slowly while observing the

" lockout" and " normal" lamps on the turbine panel .

When the " lockout" light goes out and the " normal" light comes on, the action of the Backup Overspeed Device is verified. Record this speed on the data sheet.

9. Continue increasing speed until the high speed stop of the air mot ~ is rear.hed. Record this spEad on the data sheet.
10. Back -]ff the motor speed changer handwheel until the turbine speed decreases slightly.
11. At the Control Room Operator's panel, energize SV-7 by placing the FPT " Full Range Man Speed Control" switch in the "On" position.

N0li,: In order to reach the trip speed with an air motor / MSC system it is necessary to use the SV-7 Hydraulic Jack because the fixed high speed stop of the air motor is not moveable.

By energizing SV-7, speed control is transferred entirely to the MSC.

113S 188 34.0 4

1106-3 Revision 13 07/18/79

12. Continue increasing speed using the MSC handwheel until the high speed stop is reached. Record this speed on the data sheet.

NOTE: For the overspeed test, speed should be increased slowly so that the instruments raay be observed to accurately record the speed at which the turbine trips.

13. Using a large screwdriver, depress the spring-loaded pin in the fulcrun nut and slowly turn the MaC handwheel until the pin passes the high speed stop.
14. Continue increasing the turbine speed until the trip speed is obtained.

NOTE: Trip speed should occur between 5990 RPM and 6110 RPM.

CAUTION: Do not attempt to increase turbine speed beyond the upper limit of the trip speed range. If no trip occurs within the given range, the turbine must be secured and the G.E. Co. notified.

15. Record the trip speed on the data sheet.
16. Verify all valves tripped closed.
17. Return the MSC handwheel to the low speed stop. It will be necessary to depress the spring loaded pin in the ful-crum nut.
18. Secure the turbine in a normal manner.

NOTE: If the turbine fails to trip, adjust the emer-gency governor and reperform steps 14 thru 18.
