NOTES' 1. CRW DRAINS ARE CONNECTED TO REACTOR BUILDING EQUIPMENT DRAIN SUMP. 2. DRW DRAINS ARE CONNECTED TO REACTOR BUILDING FLOOR DRAIN SUMP . 3. ALL VALVES ARE THE SAME SIZE AS PIPING, UNLESS OTHERWISE NOTED. 4. ALL VALVE DRAINS AND VENTS ARE PIPED TO CRW. 5. UNIDS ON DRAWINGS ARE FOR REFERENCE ONLY AND ARE ABBREVIATED AS

SHOWN IN THE EXAMPLE TO MEET SPACE CONSTRAINTS. REFER TO MEL FOR COMPLETE UNIDS. ALL UNIDS ARE IN UNIT 2, SYS 71 UNLESS OTHERWISE NOTED. LEADING ZEROES SHOWN IN MEL AS PART OF THE UNID ARE NOT DEPICTED. FOR ADDITIONAL GUIDANCE, REFER TO NEDP-4 . EXAMPLE: MEL UNID

6. []] ETC, DENOTES DESIGN PRESSURE THIS DRAWING.

7. DELETED

DRAWING UNID SHV-502 PT-204C

AND TEMPERATURE AS GIVEN IN TABLE,

8. THE DESIGN PRESSURE AND TEMPERATURE OF ALL DRAIN AND VENT LINES THROUGH THE LAST ISOLATION VALVE SHALL BE THE SAME AS THE PROCESS LINE .

9. CONDENSATE PUMP AND VACUUM PUMP SUCTION LINES ARE INTERNAL TO TANK AND SHOWN ONLY FOR CLARITY.

10. HYDROTESTING OF THERMOWELLS AND FITTINGS SHALL BE PERFORMED IN SHOP AT 30 PSIG. SYSTEM LEAK TEST PER ANSI B31.10 POWER PIPING CODE.

11. FOR DESIGN PRESSURE AND DESIGN TEMPERATURE SEE TERRY STEAM TURBINE MANUAL, CONTROL# 0467 (CONTRACT# 90744).

12. VENT, DRAIN AND TEST CONNECTIONS 1-1/2" AND BELOW CAN BE PROVIDED WITH PIPE CAPS OR HOSE CONNECTION FITTINGS WHERE REQUIRED BY PLANT PERSONNEL. THIS CONFIGURATION IS SUPPORTED BY ENGINEERING CALCULATION CD-00999-923399.

13. SPOOL PIECE MAY BE REPLACED BY STRAINER DURING MAINTENANCE. THE SPOOL PIECE MUST BE INSTALLED PRIOR TO RETURNING THE SYSTEM TO SERVICE. SEE 0-47E456-1. -2 FOR STRAINER DETAIL.

14. ORIFICE COUPLING, SEE 0-471600-20, DETAIL P20. 15. VALVE 2-FCV-071-0039 WILL SEAL LEAK TIGHT ONLY IN THE DIRECTION OF

FEEDWATER TO RCIC SYSTEM DUE TO A PRESSURE LOCKING ~ODIFICATION WHICH DRILLED A 1/4" HOLE IN THE FEEDWATER SIDE FACE OF THE VALVE . (DCN T41301)

16. THE PIPING COMPONENT IDENTIFIED IS A LINE STOP FITTING WITH AN INTERNAL PLUG AND BLIND FLANGE. NORMAL CONFIGURATION DOES NOT ISOLATE FLOW AND FITTING, PLUG AND BLIND FLANGE ARE CONSIDERED PRESSURE RETAINING.

NOTES:

1. THE REACTOR CORE ISOLATION COOLING SYSTEM IS DESIGNED TO COOL THE CORE WHEN THE REACTOR VESSEL IS ISOLATED AND REACTOR FEEDWATER IS UNAVAILABLE. WHEN THE WATER LEVEL IN THE REACTOR VESSEL REACHES SETPOINT, THE RCIC SYSTEM IS AUTOMATICALLY STARTED BY ACTIVATION OF REACTOR LEVEL SWITCHES LIS-3-58A, LIS-3-58B, LIS-3-58C ANO LIS-3-580 (2-47E610-3-1), ARRANGED IN ONE-OUT-OF-TWO-TWICE LOGIC TO OPEN VALVE FCV-71-8. THE SAME SIGNAL CLOSES DRAIN LINE VALVES FCV-71-SA AND FCV-71-6B.

2. A MECHANICAL SPEED GOVERNOR PREVENTS TURBINE OVERSPEED BY TRIPPING THROTTLE TRIP VALVE FCV-71-9 WHEN A TURBINE OVERSPEED OCCURS. A CONTROL GOVERNOR, FIC-71-J6, EQUIPPED WITH AUTOMATIC AND MANUAL MEANS FOR SPEED SET POINT CONTROL REGULATES TURBINE SPEED VIA "TURBINE SPEED CHANGER" TO CONTROL RCIC MAIN PUMP DISCHARGE FLOW.

3A. A RCIC STANDBY td:JDE SIGNAL SHALL BE INITIATED AT REACTOR VESSEL WATER LEVEL 8 (HIGH LEVEL). THE REACTOR VESSEL WATER LEVEL 8 SIGNAL SHALL BE INITIATED BY TWO LEVEL SWITCHES ARRANGED IN A TWO-OUT-OF-TWO LOGIC CONFIGURATION. THE REACTOR VESSEL WATER LEVEL 8 SIGNAL SHALL: (A) CLOSE THE STEAM ADMISSION VALVE FCV-71-8 AND (B) CLOSE THE MINI-FLOW ISOLATION VALVE FCV-71-34. IN THE EVENT AN INITIATION SIGNAL IS RECEIVED AFTER THE SYSTEM HAS BEEN SHUTDOWN ON HIGH RV LEVEL, THE SYSTEM SHALL BE CAPABLE Of AUTOMATIC RESTART.

3B. THE RCIC TURBINE TRIP VALVE IS TRIPPED BY: A. TURBINE OVERSPEED VIA THE SPEED GOVERNOR.

C. LOW RCIC PUMP SUCTION PRESSURE SENSED BY PS-71-21.

D. HIGH RCIC TURBINE EXHAUST PRESSURE SENSED BY EITHER PS-71-1JA OR PS-71-13B.

E. MANUALLY FROM THE MAIN CONTROL ROOM BY HS-71-9A OR BY HS-71-9C ON PANEL 25-J2.

A TURBINE TRIP,

A. CLOSES FCV-71-9. B. CLOSES FCV-71-J4. C. ANNUNCIATES ON ZA-71-49A OR 49B. D. ACTIVATES THE ALARM ASSOCIATED WITH THE CONDITION INITIATING

THE TRIP.

4. THE TURBINE CASING IS PROTECTED FROM OVERPRESSURE BY TWO RUPTURE DISCS. PS-71-11A THRU D DETECTS DISC RUPTURES AND ANNUNCIATES ON PA-71-11 IN THE MAIN CONTROL ROOM. PROVIDES 1 OUT OF 2 TWICE LOGIC TO INITIATE AUTO ISOLATION OF TURBINE (SEE NOTE 5).

5. THE RCIC TURBINE WILL BE AUTOMATICALLY ISOLATED FROM THE STEAM SUPPLY BY CLOSING ISOLATION VALVES FCV-71-2 AND FCV-71-3 IF: A. A HIGH PRESSURE DROP OCCURS ACROSS THE RCIC ELBOW TYPE FLOW

ELEMENT FE-73-1A & 18 WHEN THE STEAM LINE RUPTURES. THE HIGH FLOW IS SENSED BY EITHER PDT-71-1A OR PDT-71-1B AND ANNUNCIATED ON PDA-71-1 .

B. HIGH AREA TEMPERATURES INDICATING A STEAM LINE BREAK ARE DETECTED BY ANY OF FOUR SETS OF TEMPERATURE SWITCHES CTS-71-2A THROUGH TS-71-2S EACH SET CONNECTED IN ONE-OUT-OF-TWO-TWICE LOGIC. FOUR INDEPENDENT TEMPERATURE SENSING ELEMENTS AND ASSOCIATED TEMPTERA­TURE SWITCHES TE-71-41A AND TS-71-41A THROUGH TE-71-41D AND TS-71-41D SET AT 175" F ACTIVATE THE MAIN CONTROL ROOM ANNUNCIATOR TA-71-41.

C. LOW REACTOR PRESSURE IS DETECTED BY PS-71-1A THROUGH PS-71-1D ARRANGED IN ONE-OUT-OF-TWO-TWICE LOGIC.

D. HIGH PRESSURE BETWEEN THE TURBINE EXHAUST RUPTURE DISCS (SEE NOTE 4).

6. NORMALLY MAKEUP WATER FOR THE RCIC PUMP SUCTION IS SUPPLIED BY THE CONDENSATE STORAGE TANK THROUGH FLOW CONTROL VALVE FCV-71-19. AN ALTERNATE SOURCE OF WATER IS OBTAINED FROM THE SUPPRESSION POOL THROUGH ISOLATION VALVES FCV-71-17 AND FCV-71-18. PUMP DISCHARGE FLOW ROUTES ARE AS FOLLOWS:

A. NORMALLY VIA THE FEEDWATER LINE TO THE REACTOR THROUGH ISOLATION VALVES FCV-71-37, FCV-71-39, AND CHECK VALVE FCV-71-40.

B. DURING TESTING VIA TEST LINE TO CONDENSATE STORAGE THROUGH FLOW CONTROL VALVE FCV-71-38.

C. MINIMUM FLOW BYPASS TO THE SUPRESSION POOL THROUGH FLOW CONTROL VALVE FCV-71-34.

7. IF RCIC SYSTEM OPERATION IS REQUIRED WHEN IT IS IN THE TEST MOOE, THE CONTROL SYSTEM IS DESIGNED TO AUTOMATICALLY RETURN THE SYSTEM TO THE OPERATING MODE.

8. COOLING WATER FOR THE PUMP, TURBINE, AND LUBE OIL COOLER IS SUPPLIED FROM THE PUMP DISCHARGE LINE THROUGH PRESSURE CONTROL VALVE PCV-71-22 SET AT 75 PSIA.

9. TRANSFER AND CONTROL SWITCHES ASSOCIATED WITH BACKUP CONTROL WILL BE ON THE DESIGNATED PANELS OR LOCATED ON THE APPROPRIATE 250V DC M:JV BOARDS.

10. XS-71-36B IS SHOWN TWICE TO SHOW HOW THIS TRANSFER SWITCH DISCONNECTS FIC-71-36A AND CONNECTS FIC-71-36B LOCATED AT THE BACKUP CONTROL CENTER.

11. XS-71-24, PS-71-44, TS-71-47 & TS-71-48 ARE SHOWN TWICE TO SHOW HOW THESE SWITCHES TRANSFER INDICATION FROM THE MAIN CONTROL PANEL 9-J TO THE BACKUP CONTROL PANEL 25-J2.

12. UNIDS ON DRAWINGS ARE FOR REFERENCE ONLY AND ARE ABBREVIATED AS SHOWN IN THE EXAMPLE TO MEET SPACE CONSTRAINTS. REFER TO MEL FOR COMPLETE UNIDS. All UNIDS ARE IN UNIT 2 SYSTEM 71, UNLESS OTHERWISE NOTED. LEADING ZEROES SHOWN IN MEL AS PART OF THE UNID ARE NOT DEPICTED. FOR ADDITIONAL GUIDANCE, REFER TO NEDP-4. EXAMPLE: MEL UNID DRAWING UNID
