1.

THE OFF GAS VENT PIPE GAS SAMPLE LINE BY AE SHALL BE 1" X 0.058" WALL THICKNESS SEAMLESS STAINLESS STEEL TUBING. THE TUBING MIN-IMUM BEND RADIUS SHALL BE 20°. THE TUBING LENGTH SHALL BE JOINED WITH SWAGELOK TYPE 1610-6-316 UNIONS. THE TUBING SHALL SLOPE SO THAT CONDENSATE WILL RUN TO DRAIN TEE.

2.

REMOVABLE SECTION SHALL BE PROVIDED NEAR THE ISOKJNETIC PROBE FOR THE INSERTION OF A CHARCOAL FILTER HOLDER. THE FITTINGS ETC. SHALL PROVIDE SMOOTH TRANSITIONS WITHOUT DISCONTINUITIES GR REDUCING THE CROSS-SECTIONAL AREA OF THE FLOW STREAM.

3.

UNION TEE SWAGELOK TYPE 1610-6-316.

4.

ALARMS ARE ACTUATED BY RELAYS IN TRIP AUX UNIT PART 355.

5.

ALL EQUIP AND INSTRUMENTS ARE PREFIXED BY 17 WHICH IS PART 17 ON THE MASTER PARTS LIST.

6.

THE DETECTORS (230) SHALL BE LOCATED AS CLOSE AS PRACTICAL TO THE PRIMARY CONTAINMENT. THE DETECTORS SHALL BE ARRANGED SUCH THAT EACH DECTOR WILL VIEW ALL STEAM LINES WITH APPROXI-MATELY THE SAME RESPONSE. THE DETECTOR OR DETECTOR ASSEMBLY MAY BE FASTENED TO A ROD OR A PIPE AND INSERTED INTO SEALED PIPE WELLS FROM OUTSIDE THE STEAM TUNNEL. CAREFULLY ROUTE CABLES TO MINIMIZE HEAT EXPOSURE. NO LEAD SHIELDING IS REQUIRED.

7.

ALL CABLE SHALL COMPLY WITH GE ENGR SPEC REF A.

8.

FOR LOCATION AND IDENTIFICATION OF INSTRUMENTS, SEE INSTRU-MENT DATA SHEET LISTED IN MPL FOR EACH INSTRUMENT.

9.

ONE HIGH RADIATION OR INOPERATIVE TRIP OUT OF TWO IN TRIP SYSTEM "A" AND ONE HIGH RADIATION OR INOPERATIVE TRIP OUT OF TWO IN THIS SYSTEM "B" SHALL TURN OFF MECHANICAL VACUUM PUMP AND CLOSE MECHANICAL LINE VALVE (REF 3). ANY ONE HIGH RADIATION SHALL ALARM (RAHH)-

10. IN EACH DIVISION, THE SIGNAL FROM ONE UPSCALE TRIP OR TWO DOWNSCALE TRIPS SHALL TRIP THAT DIVISION. TRIPPING OF BOTH DIVISIONS SHALL:

A. SHUTDOWN REACTOR BUILDING VENTILATION SYSTEM AND VALVE OFF REACTOR BUILDING. B. INITIATE STANDBY GAS TREATMENT SYSTEM. C. CLOSE PRIMARY CONTAINMENT PURGE AND VENT VALVES. ANY ONE UPSCALE TRIP SHALL ALARM (RAHH)- ANY ONE DOWNSCALE TRIP SHALL ALARM (RAL)- UPSCALE TRIPS SHALL BE IN ACCORDANCE WITH THE REQUIREMENTS OF THE PRIMARY CONTAINMENT ISOLATION SYSTEM.

11. IF A HIGH-HIGH OR DOWNSCALE OR !NOP TRIP OCCURS IN EACH OF THE TWO CHANNELS, THE OFFGAS TIMER WILL INITIATE AND A CONTROL ROOM ANNUNCIATOR WILL ACTIVATE.

THE TIMER WILL IN TURN INITIATE AN OFFGAS ISOLATION. ANY ONE HIGH, DOWNSCALE OR !NOP TRIP WILL GIVE AN ALARM IN THE CONTROL ROOM. REFERENCE ENG SPECS* A. MPL 1-11 DESIGN SPECIFICATION FOR INSTRUMENT WIRE AND CABLE.
