Division of Emergency Preparedness and Engineering Response Office of inspection and Enforcement

SUBJECT:

PILGRIM 10 CTR 2.206 PETITION An August 11, 1986 memorandum from David B. Matthews of my staff to Robert S.

Wilkerson of your staff forwarded a petition to prohibit the restart of Pilgrim nuclear power plant and stated that we would request FEMA's support in prepar-ing a final response to this petition.

I am now confirining that FEMA has agreed to provide NRC with their evaluation of the offsite emergency planning and preparedness issues raised in the petition.

As discussed with a member of your staff we understand that you will provide your response by December 15, 1986.

OTHER EVENT OF INTEREST PILGRIM - STANDBY GAS TREATMENT (SBGT) SYSTEM DESIGN DEFICIENCIES NOVEMBER 3, 1986 - (R. AULUCK, NRR)

PROBLEM:

SINGLE ACTIVE FAILURES WHICH DIMINISH THE ABILITY OF SBGT SYSTEM TO PERFORM ITS SAFETY FUNCTION CAUSE:

DESIGN DEFICIENCY - REDUNDANCY NOT PROVIDED SIGNIFICANCE:

POTENTIAL FOR RELEASE EXCEEDING 10 CFR.PART 100 LIM GIVEN A SINGLE F'AILURE IN STANDBY GAS TREATMENT SYS DISCUSSION:

ON AUGUST 27, 1986, THE LICENSEE (BECO) CONCLUDED THAT SINGLE' ACTIVE FAILURE OF SBGT DELUGE SYSTEM DURING POSTULATED D LOCA OR FUEL HANDLING ACCIDENT COULD RESULT IN OFFSITE DOSE EXCEEDING'PART 100 LIMITS.

- INADEQUATE SBGT SYSTEM / DELUGE SYSTEM INTERACTION CONSIDE THE ORIGINAL DESIGN.

- DELUGE SYSTEM PROVIDL' COOLING AND FIRE PROTECTION SPRAY IN

' RESPONSE TO HIGH TEMPERATURES IN SBGT CHARC0AL FILTERS.

i - INITIATION OF THE DELUGE SYSTEM DUE TO FAILURE OF ANY OF THE AC COMPONENTS WILL RESULT IN SOAKING OF CHARC0AL BEDS AND'THUS RENDERING THAT TRAIN INCAPABLE OF FURTHER IODINE FILTRATION; THUS SYSTEM CANNOT MEET DESIGN BASIS ON OCTOBER 30, 1986, THE LICENSEE (BECO) INFORMED NRC ABOUT TWO ADDITIONAL DESIGN DEFICIENCIES

- FAILURE OF THE CROSSOVER DAMPER RESULTING IN NO COOLING FLOW GASES THROUGH THE STANDBY TRAIN.

- SINGLE FAILURE RESULTING IN A HEATER FAILURE AND LACK OF HUMIDITY CONTROL

zm:ma:.w5 n.v.a;t.w.w.wp.ww ::u+3. nn:.%n . :1z.t z.an?:q 6 x. .u2:a ..

DISCUSSION: CONTINUED l

DAMPER FAILURE

- CROSS TIE DAMPER PROVIDES THE REQUIRED FLOW' PATH THROUGH EITHER FILTER TRAIN WHEN THAT TRAIN IS IN STANDBY.

- PARTIAL OR FULL CLOSURE OF THE DAMPER COULD LEAD TO ELE TEMPERATURES OR FIRE IN THE STANDBY TRAIN.

- PARTIAL OR FULL CLOSURE'WILL INTERRUPT FLOW'THROUGH B THUS SYSTEM:CANNOT MEET DESIGN BASIS.

~

HEATER FAILURE

- FOR CHARC0AL FILTERS TO NAINTAIN THEIR EFFICIENCY FOR FILTERING OUT RADIOI0 DINES THE HUMIDITY OF THE AIR STREAM MUST BE CONTROLLED FOR BOTH PRIMARY AND STANDBY TRAINS.

- IN THE PRESENT DESIGN, THE HEATERS DO NOT HEAT THE AIR PASSING THROUGH THE STANDBY TRAIN ONCE FAN IS DE-ENERGIZEDTHUS, SYSTEM CANNOT MEET DESIGN BASIS

- FAILURE;0F THE HEATER AC POWER OR TEMPERATURE SWITCH ON THE ACTIVE TRAIN COULD ALSO IMPACT OPERABILITY FOLLOW-UP:

LICENSEE WILL RE-EVALUATE DESIGN BASIS DESIGN MODIFICATIONS WILL BE COMPLETED AS NECESSARY

WITH ALL TRIP FUNCTIONS OF SRM "C" INOPERABLE, 19 FUEL BUNDLES WERE LOADED IN THE QUADRANT, CONTRARY TO TS REQUIREMENTS ON 11/08, THE RAD MONITOR FOR THE REACTOR BUILDING BELOW THE REFUELING FLOOR WAS REMOVED FROM SERVICE FOR MAINTENANCE WHILE FUEL LOADING WAS IN PROGRESS; CONTRARY TO TS REQUIREMENTS, THE STANDBY GAS TREATMENT SYSTEM WAS NOT PLACED IN SERVICE ON 11/09, TWO APRM-HI TRIPS ON CHANNEL ^C" WERE RECEIVED.

- THE FIRST WAS ATTRIBUTED TO WELDING IN THE AREA 0F THE LPRM CABLES

- AFTER THE SECOND OCCURRED WITH NO WELDING IN PROGRESS, A FAULTY CARD IN THE LPRM CIRCUITRY WAS FOUND. ,

DURING FUEL LOADING, ROD BLOCKS WERE BYPASSED DUE TO A TRAINING PROBLEM, CONTRARY TO TS REQUIREMENTS FOLLOWUP: I REGION IS FOLLOWING OPERATIONS CLOSELY AND DISCUSSING EVENTS WITH LICENSEE ENFORCEMENT CONFERENCE ON TS VIOLATIONS TO BE SCHEDULED IN EARLY DECEMBER LICENSEE IS TAKING CORRECTIVE ACTIONS, (E.G. DISCIPLINARY ACTION)

OTHER EVENT OF INTEREST PILGRIM - FIRE WATER SYSTEM INOPERABLE NOVEMBER 10, 1986 (R. AULUCK, NRRl PROBLEM: NON AVAILABILITY OF WATER FOR THE FIRE SUPPRESSION WATER SYSTEM CAUSE: INCORRECT LABELING OF THE VALVES SIGNIFICANCE: LACK 0F FIRE PROTECTION CAPABILITY IN MANY AREAS OF THE STATION DISCUSSION:

ON NOVEMBER 5, 1986, WATER TANK "B" WAS DRAINED IN ORDER TO WORK ON THE HEATING C0ILS.

ON NOVEMBER 10, WHILE ATTEMPTING TO FLUSH TANK "B" WITH FIRE H0SE, THE PUMPS TRIPPED ON LOW SUCTION PRESSURE. ELECTRIC PUMP '

-DAMAGED BUT DIESEL DRIVEN PUMP REMAINED OPERABLE.

BEC0 FOUND THAT THE LOW SUCTION PRESSURE WAS CAUSED BY THE TANK'S l

SUCTION VALVES BEING MIS-LABELED RESULTING IN THE ISOLATION OF THE "A" TANK INSTEAD OF THE "B" TANK.

VALVES LABELED INCORRECTLY SINCE PLANT FIRST PUT INTO SERVICE.

MIS-LABELING WAS CORRECTED AND THE SYSTEM RESTORED.

ERROR ALSO DISCOVERED IN THE SYSTEM P81D. TANK "A" FEEDS TO MOTOR DRIVEN PUMP AND NOT THE DIESEL DRIVEN PUMP AS SHOWN. ,

BACKUP SUPPLY OF FIRE WATER WAS AVAILABLE CITY WATER FROM ONE OF TWO HYDRANTS AGREEMENT WITH THE LOCAL FIRE DEPARTMENT RESIDENT INSPECTOR PERFORMED AN INSPECTION ON THE MAINTENANCE HISTORY OF THE SYSTEM. NO OTHER PROBLEMS NOTED.

FOLLOWUP:

LICENSEE TO REVISE P&ID AND PLANT PROCEDURES PER PLANT TECH SPECS, THE LICENSEE TO SUBMIT A REPORT TO THE COMMISSION OUTLINING THE CAUSE OF THE MALFUNCTIONS AND THE ACTIONS TAKEN REGION FOLLOWING LICENSEE'S FOLLOWUP ACTION

PROBLEM:

MAIN FEED PERTURBATION CAUSED EFW ACTUATION STEAM-DRIVEN EFW PUMP TRIPPED ON OVERSPEED (ELECTRIC PUMP STARTED AS DESIGNED)

CAUSE:

AUX STEAM VALVE MALFUNCTION, POSSIBLE OPERATOR ERROR

)

EFW STEAM-DRIVEN PUMP TRIP ON OVERSPEED PROBABLY DUE TO WATER IN LINE .

SIGNIFICANCE:

EFW RELIABILITY MAY BE LESS THAN DESIRABLE (ONE OF SEVEN PLANTS WITH ONLY TWO TRAINS OR EFW)

MFW RELIABILITY QUESTIONABLE AT LOW POWER LEVELS AND TRANSITION POINTS DISCUSSION:

PLANT AT 20% POWER SHUTTING DOWN FOR CRDM PROBLEM OPENED MANUAL VALVE ON AUX STEAM LINE IN PREPARATION TO SWITCH FROM MAIN STEAM FOR MFW TURBINE PRESSURE CONTROL VALVE (PCV) ON AUX STEAM WENT WIDE OPEN, SHUTTING MAIN STEAM PRESSURE CONTROL VALVE TO MFW TURBINE OPERATORS CLOSED AUX STEAM MANUAL VALVE MAIN STEAM PRESSURE CONTROL VALVE COULD NOT OPEN FAST EN0 UGH TO MAINTAIN PUMP SPEED - MFW FLOW DECREASED AND OTSG LEVEL DROPPED TO EFIC ACTUATION SETPOINT EFIC INITIATED EFW. BOTH ELECTRIC AND STEAM PUMP STARTED, BUT STEAM TURBINE TRIPPED ON OVERSPEED POSSIBLE CAUSE OF OVERSPEED TRIP - EFW STEAM BYPASS VALVE CLOSED, WHICH PREVENTED SMALL STEAM FLOW TO KEEP LINE HOT AND ALLOWED BUILDUP 0F WATER IN LINE FOLLOWUP:

NOTES 1.- - PLANT SPECIFIC DATA BASED ON INITIAL REVIEW OF 50.72 REPORTS FOR THE WEEK OF INTEREST. PERIOD IS HIDNIGHT SUNDAY THROUGH MIDNIGHT SUNDAY SCRAMS ARE DEFINED AS REACTOR PROTECTIVE ACTUATIONS WHICH RESULT IN ROD MOTION, AND EXCLUDE PLANNED TESTS OR SCRAMS AS PART OF PLANNED SHUTDOWN IN ACCORDANCE WITH A PLANT PROCEDURE.

2. RECOVERY COMPLICATED BY EQUIPMENT FAILURES OR PERSONNEL ERRORS UNRELA.TED TO CAUSE OF SCRAM.

3. 1985 INFORMATION DERIVED FROM RECENT ORAS PRELIMINARY STUDY OF UNPLANNED REACTOR TRIPS IN 1985. WEEKLY DATA DETERMINED BY TAKING TOTAL TRIPS IN A GIVEN CATEGORY AND DIVIDING BY 52 WEEKS / YEAR.

. 4. IN 1985 THERE WERE AN ESTIMATED TOTAL OF 541 AUTOMATIC AND MANUALUNPLANNEDREACTORTRIPSAT93 REACTORS (HOLDINGFULL POWERLICENSES). THIS YIELDS AN AVERAGE RATE OF 5.B TRIPS PER REACTOR PER YEAR AND AN AVERAGE RATE OF 10.4 TRIPS PER WEEK FOR ALL REACTORS.

5. BASED ON 100 REACTORS HOLDING A FULL POWER LICENSE.

i

6. PERSONNEL RELATED PROBLEMS INCLUDE HUMAN ERROR, PROCEDURAL DEFICIENCIES, AND MANUAL STEAM GENERATOR LEVEL CONTROL PROBLEMS.

7. *0THER" INCLUDES AUTOMATIC SCRAMS ATTRIBUTED TO ENVIRONMENTAL CAUSES(LIGHTNING),SYSTEMDESIGN,ORUNKNOWNCAUSE.
