PROCEDURE TO STARTUP A CHLORINE RECTIFIER THIS PROCEDURE IS TO BE REVIEWED PRIOR TO THE STARTUP OF A CHLORINE RECTIFIER BY THE POWER 2 SHIFT SUPERVISOR AND BOARD SOS. 1. MAINTAIN COMMUNICATIONS WITH THE CHLORINE PLANT AND/OR POWER I AS TO WHAT CIRCUIT IS TO BE BROUGHT ON LINE AND WHEN. EMPHASIZE TO YOUR CONTACTS THAT POWER 2 NEEDS TO BE COMMUNICATED WITH JUST PRIOR (WITHIN 1 MINUTE) TO PLUG IN. MAKE SURE THAT THE CIRCUIT IS COMING UP ON THE LOWEST TAP. 2. COMMUNICATE CHLORINE'S INTENTIONS TO POWER 1 IN CASE THE CHLORINE PLANT HAS NOT MADE THAT COMMUNICATION. KEEP POWER I INFORMED OF THE CHLORINE PLANT'S STATUS. 3. REVIEW THE ELECTRICAL ONE-LINE DRAWING IN THE CONTROL ROOM TO SEE WHAT ELSE IS FED FROM THE BUS THAT THE UPCOMING CIRCUIT IS ON. CONSIDERATION SHOULD BE GIVEN TO THE GENERATORS THAT MAY BE DOWN. COMMUNICATE ANY CONCERNS TO POWER I. 4. COMMUTATION SHOULD BE MADE WITH ANY PLANTS WITH FEEDERS ON THE SAME BUS THAT MAY BE AFFECTED.

HYDROGEN GAS IS SUPPLIED FROM A COMPRESSED GAS CYLINDER TRAILER, REGULATED TC 45 PSIG, AND SENT TO THE CONTROL CABINET. A REGULATOR VALVE IN THE CABINET MAINTAINS CASING PRESSURE AT 30 PSI. THERE IS A BY-PASS VALVE AROUND THIS REGULATOR FOR EMERGENCY USE. THERE IS A 5 PSI REGULATOR IN THE SYSTEM, NORMALLY OUT OF SERVICE AND ISOLATED FROM THE 30 PSI SYSTEM BY A CHECK VALVE, WHICH COMES IN TO MAINTAIN 5 PSI IN THE GENERATOR CASING ON LOSS OF SEAL OIL PUMPS. UNDER THESE CONDITIONS, SEAL OIL WOULD BE SUPPLIED FROM THE BEARING OIL HEADER, NECESSITATING REDUCED HYDROGEN PRESSURE IN THE GENERATOR. EXCESSIVE GAS PRESSURE WOULD BE VENTED AUTOMATICALLY. HYDROGEN PURITY IN THE GENERATOR CASING MUST BE MAINTAINED IN THE 90-957. RANGE. THIS IS ACCOMPLISHED BY VENTING A SMALL AMOUNT OF GAS FROM THE SEAL OIL DETRAINING CHAMBERS AT EACH END OF THE GENERATOR. THIS SCAVENGE GAS FLOW IS CONTROLLED THROUGH THE TWO FLOWMETERS MOUNTED ON THE FRONT OF THE HYDROGEN CONTROL CABINET. INCREASING PURITY (ABOVE 957.) SIGNALS THE NEED TO REDUCE THE SCAVENGE RATES THROUGH THESE FLOWMETERS, AND OF COURSE, VICE VERSA. ALSO MOUNTED ON THE FRONT OF THE CONTROL CABINET IS A PUSH BUTTON WHICH ALLOWS MANUAL OPERATION OF THE SOLENOID-OPERATED VENT VALVES IN THE SCAVENGE GAS LINES FROM THE DETRAINING CHAMBERS. OPERATION OF THIS PUSH BUTTON WOULD ALLOW RAPID VENTING OF GAS FROM THE DETRAINING CHAMBERS, RESULTING IN AN INCREASE OF PURE HYDROGEN FLOW TO THE MACHINE AS A MEANS OF CORRECTING SITUATIONS OF DANGEROUSLY LOW PURITY. SEAL OIL SYSTEM IN ORDER TO CONTAIN HYDROGEN GAS IN THE GENERATOR CASING, SEAL OIL IS APPLIED TO THE SEAL RINGS AT EACH END OF THE MACHINE AT 5 PSI GREATER THAN THAT OF THE GAS IN THE CASING. UNDER NORMAL OPERATING CONDITIONS, THIS OIL IS SUPPLIED BY AN AC MOTORDRIVEN PUMP, TAKING SUCTION FROM THE BEARING OIL HEADER AND DISCHARGING AT 65 PSI TO THE DIFFERENTIAL PRESSURE REGULATOR WHICH MAINTAINS PRESSURE AT THE GENERATOR SEALS 5 PSI HIGHER THAN THE CASING GAS PRESSURE. ON LOSS OF THE AC SEAL OIL PUMP, DUE TO POWER FAILURE OR WHATEVER, A DC MOTOR DRIVEN PUMP IS PROVIDED AS A BACKUP. AS STATED PREVIOUSLY, NORMAL SUCTION SUPPLY TO THE SEAL OIL PUMPS IS FROM THE BEARING OIL HEADER. HOWEVER, ON LOSS OF PRESSURE ON THIS SYSTEM, THE SEAL OIL PUMP WILL TAKE SUCTION FROM THE MAIN LUBE OIL TANK AND/OR FROM THE SEAL DRAIN TANK. IT SHOULD BE REMEMBERED, HOWEVER, THAT ON LOSS OF BEARING OIL PRESSURE IT IS NECESSARY TO CLOSE THE BLOCK VALVE FROM THE SYSTEM TO THE SEAL OIL PUMP SUCTION HEADER. EXPERIENCE HAS ^ SHOWN THAT IF THIS VALVE IS LEFT OPEN UNDER THESE CONDITIONS, THE SEAL 2 o OIL PUMP SOON BEGINS TO CAVITATE, APPARENTLY DRAWING IN AIR FROM THE ^ 'DEAD' LINE. z THERE ARE TWO OTHER BACKUP SYSTEMS THAT WILL SUPPLY SEAL OIL ON LOSS =! $ OF BOTH AC AND DC PUMPS.

IT IS NOT KNOWN WHAT THE FAILURE MODE WILL BE NOR HOW IT WILL AFFECT THE TURBINE OPERATION. WE HAVE HAVE HAD A U-DUCT FAILURE HERE AT POWER 2 BUT UNFORTUNATELY WE DO NOT HAVE VERY MUCH DATA ON HOW THE VARIABLES WILL CHANGE DURING THE FAILURE. THE ONLY THING ABSOLUTE IS THAT THE REGENERATOR AIR FLOW WILL GO DOWN. FOR THIS REASON, AUTOMATIC TRIPS WILL BE SET UP TO SHUT DOWN THE TURBINE IF THE REGENERATOR AIR FLOW FALLS BELOW A SET AMOUNT. MANUAL OPERATOR TRIPS WILL BE REQUIRED IF A REGENERATOR AIR FLOW REDUCTION OCCURS ALONG WITH OTHER KEY PARAMETER CHANGES. IT IS NOT KNOWN IN WHAT DIRECTION THESE OTHER PARAMETERS WILL MOVE, THEREFORE CHANGES IN ANY DIRECTION ARE SIGNIFICANT. 1. AUTOMATIC TRIPS ARE BEING INSTALLED ON GT-lOO AND GT-200 TO TRIP THE MACHINE ON LOW REGENERATOR AIR FLOW. THE TRIPS WILL BE SET AT 1300 MLB/HR. THE TRIPS WILL REQUIRE TWO TRANSMITTERS TO READ LOW TO ACTIVATE. GT-lOO ONLY HAS ONE TRANSMITTER AT PRESENT, BUT A SECOND TRANSMITTER WILL BE ADDED ON THE NEXT OUTAGE. THE TRIPS WILL BE ACTIVE ON AFTER THE TURBINE RPM'S ARE GREATER THAN 3600. 2. OPERATORS SHOULD MANUALLY TRIP THE UNIT IF THE FOLLOWING CONDITIONS EXIST: - THE REGEN AIR FLOW LOW ALARM HAS ACTIVATED ON ANY OF THE AVAILABLE FLOW INDICATIONS. THE ALARMS ARE SET APPROXIMATELY 100 MLB/HR LESS THAN THE NORMAL OPERATING FLOWS. AND - ANY CHANGE IS OBSERVED ON ANY OF THE FOLLOWING ITEMS: A. GENERATOR MEGAWATTS B. PYROMETER TEMPERATURE C.

SPECIAL NOTE: THE TRI-SEN PROGRAM LOGIC WILL ALLOW THE MACHINE TO RUN AS LONG AS THERE IS ONE UNFAILED PROBE. THE LOGIC IS SET THIS WAY ONLY TO PROVIDE SOME TIME TO PLAN AND CONDUCT A CONTROLLED SHUTDOWN OF THE UNIT. CONTINUED OPERATION WITH ONLY A SINGLE PROBE IS NOT WITHIN THE GUIDELINES OR SUPPORT OF THE TECH CENTER. OTHER THAN TO PLAN AND CONDUCT A SHUTDOWN. SYSTEM DESCRIPTION GT-100/200 SPEED LOGIC USES THREE SPEED PROBES FOR DETERMINING THE SPEED OF THE MACHINE. THE PROGRAM VERIFIES THAT EACH SPEED INPUT IS "GOOD" AND THEN MEDIUM SELECTS THE SPEED. MEDIUM SELECT IS THE MIDDLE VALUE. THE PROGRAM CONTINUES TO MEDIUM SELECT UNTIL ANY ONE PROBE FAILS. ONCE A PROBE FAILS, THE PROGRAM THEN USES "HIGH SELECT" FOR DETERMINING MACHINE SPEED AND CONTINUES TO USE HIGH SELECT UNTIL THERE ARE THREE GOOD INPUTS AND THEN IT WILL RETURN TO MEDIUM SELECT. THE VERIFICATION OF THE SPEED INPUTS IS A CHECK TO ENSURE THAT THE PROBE'S INPUT IS GREATER THAN 200 RPM. THE VERIFICATION STEP DOES NOT OCCUR UNTIL THE IGNITION STEP IS COMPLETE. IF A PROBLE IS DETECTED TO BE BELOW 200 RPM, THE PROGRAM WILL FAIL THAT PROBE AND FORCE THAT INPUT TO ZERO. THE HIGH SELECT LOGIC WILL ALSO BE ACTIVATED. NOW THE PROGRAM WILL CONTROL OFF THE HIGHEST OF THE TWO REMAINING PROBES. AT THIS POINT, THERE ARE TWO SCENARIOS THAT CAN TAKE PLACE: IF ONE OF THE PROBES DROPS BELOW 200 RPM, IT WILL BE FAILED AND CONTROL WILL CONTINUE ON THE ONE REMAINING PROBE. AS THIS PROBE'S INPUT CHANGES THE PROGRAM WILL RESPOND TO TRY AND MAINTAIN 3600 RPM. IF THE INPUT BEGINS TO DROP. THE MACHINE WILL TRY TO PICK UP SPEED. IF THE INPUT REACHES 3950 RPM, THE MACHINE WILL TRIP ON OVERSPEED. IF THE SPEED DROPS BELOW 3400 RPM THE MACHINE WILL TRIP ON UNDERSPEED. IF THE INPUT BEGINS TO INCREASE, THE MACHINE WILL TRY AND REDUCE SPEED. 2. IF ONE OF THE PROBES BEGINS TO READ ABOVE 3600 RPM, THE PROGRAM WILL TAKE THAT VALUE AS THE MACHINE SPEED AND REACT ACCORDINGLY. THE PROGRAM WILL "THINK" THAT THE MACHINE IS IN AN OVERSPEED CONDITION AND IT WILL TRY TO REDUCE THE SPEED. SHOULD THE SPEED INPUT REACH 3950 RPM, THE MACHINE WILL TRIP ON OVERSPEED. FAILURE RESPONSE OPERATIONS RESPONSE TO THE FIRST PROBE FAILURE IS: 1. GO TO THE SPEED INPUT SCREEN AND LOOK AT THE THREE SPEED INPUT VALUES. NOTE WHICH PROBE HAS FAILED. VERIFY THAT THE REMAINING TWO PROBES ARE STABLE AND READING THE SAME VALUE OF 3600 RPM. 2. NOTIFY THE I&E ENGINEER OF THE FAILURE. OPERATIONS RESPONSE TO THE SECOND PROBE FAILURE IS: no A 133*5? r.ONFTOFNT I Al 1. GO TO THE SPEED INPUT SCREEN AND LOOK AT THE THREE SPEED INPUT VALUES NOTING WHICH PROBES HAVE FAILED. VERIFY THAT THE ONE REMAINING PROBE IS READING 3600 RPM. 2. NOTIFY POWER 1 OF THE SITUATION AND THAT IF THE LAST SPEED PROBE FAILS, THE MACHINE WILL TRIP. DISCUSS THE EFFECTS OF SHUTTING THE MACHINE DOWN TO CORRECT THE PROBLEM. 3. NOTIFY PLANT SUPERINTENDENT OF THE SITUATION AND THE NEED TO REPAIR THE SPEED INPUTS. DISCUSS SHUTTING THE MACHINE DOWN.

MONITOR THE STATIC PRESSURE INDICATION ON THE COMPRESSOR INFORMATION PAGE OF THE PDP-11. 5. INSPECT THE INLET ON THE SIDES. BOTTOM. AND TOP TO DETERMINE WHY THE FILTERS MAY BE PLUGGING UP AND IF THE AWC WOODEN WALLS ARE STILL INTACT. SOMETIMES RAIN CAN LEAK INTO THE AWC DOWNSTREAM OF THE DEMISTERS. POSSIBLY OVER THE FILTERS. CAUSING THEM TO PLUG UP. 6. VERIFY THAT THE AWC LEVEL IS ADEQUATE. IF THE LEVEL IS TOO HIGH (ABOVE SO*/.) WATER GETS BLOWN ONTO THE FILTERS AND UP INTO THE TURBINE INLET. A LOW LEVEL (BELOW 6OX) WILL ALLOW AIR TO BYPASS THE FILTERS THROUGH A HOLE WHICH EXISTS IN THE SEPARATING WALL. (THIS MIGHT SHOW UP AS A LOW FILTER DIFFERENTIAL PRESSURE THOUGH. ) SHUTTING DOWN THE AWC PUMPS WILL ALLOW DRY AIR TO PASS THROUGH THE FILTERS THEREBY DRYING THEM OUT, ASSUMING THEY HAVE GOTTEN WET. MONITORING THE DELTA-P INDICATION ON THE STRIP CHART AND PICS DISPLAY WILL GIVE SOME INFORMATION ON WHETHER THE SITUATION IS WORSENING. MONITORING THE STATIC PRESSURE INDICATION ON THE PDP-11 WILL GIVE MORE INFORMATION ABOUT THE FILTER CONDITION. THE STATIC PRESSURE INDICATION IS ACTUALLY THE VACUUM RIGHT AT THE INLET OF THE COMPRESSOR IF THE STATIC PRESSURE IS HIGH, THE VACUUM IS HIGH AND THE COMPRESSOR IS SUCKING HARD. THE FILTERS MAY BE PLUGGING UP OR, IF THE TEMPERATUR IN THE INLET IS BELOW 40 DEG. F, ICE MAY BE FORMING SOMEWHERE IN THE INLET. DO A 133854 FURTHER ACTION STEPS: OONFTDFNTTAt 1.WHEN THE AWC DELTA-P INDICATION REACHES 4. 5 INCHES OF WATER DIFFERENTIAL, THE HINGED DOORS ON THE AWC WALLS NEXT TO THE FILTERS SHOULD BE WEDGED OPEN. THIS WILL ALLOW AIR TO BYPASS THE FILTERS AND PREVENT THEM OR THE WOOD INLET WALLS FROM FAILING. THIS MUST BE DONE CAREFULLY AS THE DOORS ARE DIFFICULT TO OPEN WHILE THE MACHINE IS RUNNING. ALSO BE CAREFUL NOT TO LET ANYTHING GET PULLED INTO THE INLET. CONTACT THE AREA ENGINEER, PRODUCTION SUPERVISOR, OR PLANT SUPERINTENDENT. 3. IF THE DELTA-P INDICATION READS FULL SCALE THEN WE ARE OPERATING WITHOUT KNOWING THE TRUE DIFFERENTIAL PRESSURE. THE DELTA-P COULD WORSEN WITHOUT US KNOWING AND THE STATIC PRESSURE WOULD RISE DUE TO A HIGH VACUUM. UNDER THESE CONDITIONS, IT IS ADVISEABLE TO CONSIDER SHUTTING DOWN THE TURBINE DUE TO A POTENTIAL OF SUCKING IN THE AWC WALLS. THE FULL SCALE V READING ON THE DELTA-P TRANSMITTER IS 5 INCHES OF WATER.

IF THE TURBINE HAS TO BE COOLED DOWN FOR ANY REASON, THE UNIT CAN BE PUT ON STARTING MOTOR, USING THE NORMAL START STEPS. THE UNIT MAY BE KEPT ON STARTING MOTOR FOR AS LONG AS NECESSARY TO COOL THE UNIT. THE STARTING MOTOR SHOULD BE RUN AT MAXIMUM RPM'S FOR THE COOL DOWN CYCLE. AS THE TURBINE COOLS, THE STARTING MOTOR SPEED SHOUL.D BE LOWERED TO HAVE THE COMPRESSOR DISCHARGE TEMPERATURE LOWER THAN THE EXHAUST TEMPERATURE.
