6.

STAB. VALVE F007B IS AN ALTERNATE STAB. VALVE F007A (C-2).

7.

PROVIDE VENT A~D RAIN VALVES WITH CAP ON DISCHARGE SIDE AT AU. SYS.

8.

UNLESS OTHERWISE SHOWN:

ALL INSTRUMENT PiS NUMBERS ARE PREE!XED C11 ALI_ VALVE,\\ND EQUIPMENT PIS NUMBERS ARE PREFIXED C1100

9.

INSTRUMENT PILOT SOLENOID AND CONTROL AIR PIPING SHAi.L BE OF A NON CORROSIVE MATERIAL

10. INDICATING LIGHTS ARE AN INTEGRAL PART OF ALL PB OR C:.IC TYPE SW!TCHES UNLESS OTHERWISE NOTED.

11.

12.

13. PIPE SIZES SHOWN ON THiS DRAWING ARE APPROX. EXCEPT Ar POL\\ TS OE CONNECTION WITH G.E. SUPPLIED EQUIPMENT OR PIPING.

THE PIPING DESIGNER SHALL CHECK AND ADJUST PIPE SiZE IN ACCORDANCE WITH THE SYSTEM JESIGN SPECIFICATION AND PROCESS DIAGRAM.

14.

15. SOURCE 0" CRD SYSTEM WATER SHALL BE NORMALLY CROM CONDENSATE PO'JSHING DEMIN. SYSTEM.

CONDENSATE STORAGE IS AN ALTERNATE SOURCE IF THE TREATMENT SYSTEM IS NOT IN OPERATiON.

16. CONll\\UOUS FLOW TO REACTOR SAMPLE s-ATION SHOULD BE A0 PROX. ONE (1) cl-ER PER MINUTE AND S,oALL BE TWO AND ONE HALF (2 '. /2) LITERS PER MINUTE !JAX.

17. EXHAUST WA"ER FLOW FROM ONE iJOV'NG DRIVE IS DISPERSED VIA T"E HYDRAUclC CONTROL UNlfS OF OTHER NON MOVING JRIVES TO REACTOR PRC:SSURE VESSEL VA EXAUST WATER clNES.

18.

19.

20. TIIESE VALVES MUST BE OPEN FOR DRIVE MOVEMENT.

21. ORIFICES C11520008A, B, C, AND D ARE CONNECTED IN SEqlES AS SHOWN ON DRAWING i-2113-11.

THE PRESSURE DROP ACROSS EACH ORIFICE IS 250 PSI AT PUMP RUN OUT CONDITION. VALVE F034 SUPPL.E\\IENTS THE ORIFICES FOR THE REQLIRED PRESSURE DRCP.

22. -HE SCRAM DISCHARGE VOLUME ARRANGEMEN, SHOWN IS FOR REFE,ENCE ONLY.

SEE CRD DESIGN SPEC. FOR REQUIREMENT.

23. PIPING QUALITY CLASS EXTENDS TO CONNEC,IONS WITH HCIJ.

HCU DIAGRAM IS SHOWN FOR INFO. ONLY.

FOR QUALITY CLASS OF THE HCU, SEE GROUP CLASSIFICATION DIAGRAM.

24. SCRAM DISCHARGE DRAIN MUST BE SUBMURGED DUE TO POTENTIAL RELEASE OF STEAM ANO RADIOACTIVE NONCONDENSIBLES.

25. VALVE <1598 SHALL BE LOCKED INCO OPEN POSITION TO MAINTAIN ADMINISTRATIVE CONTROL. SEE M-5449.

26. THE C7'A-K24A AND K243 RELAYS SHALL BE SET SO 0 HAT THE F010 AND F011 VALVES MUST START TO OPEN AT LEAST FIVE (5) SECONDS AFTER THE F180 AND F181 VALVES RESPECTIVELY UPON THE RESET OF A FUcL CORE SCRAM. SEE M-5449.

27.

28.

"HE SCRAM DISCHARGE VOLUME VENT LINE SHALL BE ROUTED VIA A DEDICATED L!NE TO THE NON SUBMERGEJ DISCHARGE.

THE VENT SYSTEM PIPING SHOULJ NOT CONTAIN SIGNIFICANT FLOW.'lESTRICTIONS WHICH COULD iNHIBIT VENTING OF THC: SCRAM DISCHARGE VOLUME TO THE EXTEN7 OF LMl~ING THE SCRAM DISCHARGE VOLUME DRA!N RATE.

THE DESIGN OF THE NON SUBMERGE VEN1 DISCHARGE :.!UST CONS'DTR THE POTENTIAL FOR '<ELEASE OF RAD!OACTIVITY JUE TO THE DISCHARGE OF NON CONDENSIBLES, '//ATE, AND STEAM WHICH MAY OCCUR DURING THE PERIOD AFTER SCRAM PRIOR TO VENT VALVE CLOSURE AND UPON SCRAM RESET WHEN THE VALVES ARE REOPENED WITH THE SCRAM DISCHARGc VOLUME PRESSURIZED.

TO PREVENT LOOP SEALS FRCM OCCURING IN THE RELATIVELY SMALL DIAMETER LINES OF THE SCRAM OISCHAcsGE VC'.LJME (SJV) VENT & )RAIN SYSTEM.

A CONTINUOUS DOWNWARD PITCH AWAY FROM THE SCRAM D!SCHARGE VOLU\\IE (SVD)

VENT AND DRAIN VALVES MUST BE MAINTAINED.

• HERMAL EXPANSION EFFECTS SHOULD BE ADDRESSED IN THE DESIGN OF THE VENT AND DRAIN SYSTEMS.
