N GRAND GULF UNIT 1 - TDI DIESEL GENERATOR OVERSPEED NOVEMBER 6, 1985, (L. L. KINTNER, NRR)
PROBLEM:
TDI DIESEL. GENERATOR II OVERSPEED EVENT DAMAGED MAJOR COMP 0NENTS OF THE ENGINE SIGNIFICANCE:
l POSSIBLE GENERIC CONCERN REGARDING MAINTENANCE PROCEDURES FOR WOODWARD GOVERNOR.
OVERSPEED TRIP FUNCTION MAY NOT PROTECT AGAINST EXCESSIVE OVERSPEED DURING FAST ENGINE STARTUP IF ELECTRIC GOVERN 0R IS INOPERABLE.
CIRCUMSTANCES:
ENGINE OPERABILITY POST-MAINTENANCE TEST DURING PLANT OUTAGE FOLLOWING SCHEDULED PREVENTIVE MAINTENANCE OF GOVERN 0R UNEXCITED START - NO ELECTRIC GOVERNOR FUNCTION PER 2
PROCEDURE, FUEL RACK FULL OPEN, TRIPPED ON OVERSPEED AND MANUALLY, TOTAL RUN TIME 45 SEC, SEVERE VIBRATIONS.
t CAUSE:
WOODWARD MANUALS IN USE AT GGNS DID NOT SPECIFY VENTING /
BLEEDING AIR FROM GOVERNOR DURING P/M.
VENTING / BLEEDING IS SPECIFIED IN LATEST WOODWARD MANUALS.
MECHANICAL GOVERNOR WAS INCORRECTLY SET TO 470 RPM DURING TEST RATHER THAN TO 350 RPM AS CALLED FOR BY NORMAL POST-PM PROCEDURE.
l i
. 2 FOLLOWUP PEAK ENGINE SPEED UNDER INVESTIGATION ENGINE DISASSEMBLY AND INSPECTION BEING PERFORMED, NUMEROUS PARTS IN DAMAGED OR DISTRESSED CONDITION: PARTICULARLY CONROD BEARINGS, MAIN BEARINGS, LINK PIN BUSHINGS, AND ENGINE BASE, WILL REPLACE ALL CONROD AND MAIN BEARINGS, ONE CONROD, AND OTHER PARTS AS NECESSARY/ PRUDENT, SIGNIFICANCE OF ENGINE BASE CRACKS ARE UNDER EVALUATION SENT GOVERNOR TO MANUFACTURER (WOODWARD) FOR TESTS IN AS-FOUND CONDITION (INCLUDING INSUFFICIENT OIL),
TDI OWNERS GROUP INFORMED OF INCIDENT BY NRC STAFF AND LICENSEE, SENT REPRESENTATIVES TO SITE TDI PROJECT GROUP OBSERVED DISASSEMBLED UNIT AND WILL F0LLOW-UP ON PLANNED INSPECTIONS AND REPAIR.
A DIESEL CONSULTANT WILL VISIT SITE THIS WEEK REGION II AND RESIDENT INSPECTOR WILL FOLLOW-UP ON REPAIRS AND RESTART IE EVALUATING NEED FOR IE NOTICE 1

FERMI UNIT 2 - ENGINE FAILURE OF EMERGENCY DIESEL NOVEMBER 13, 1985, (M. D. LYNCH, DL)
PROBLEM:
FAILURE OF MAIN BEARINGS IN EDG NO. 13 (DIV.2) CAUSED SEVERE DAMAGE SAFETY SIGNIFICANCE:
LOSS OF AN EDG WILL CAUSE LOSS OF ONE DIVISION OF ON-SITE POWER SUPPLY CASTS DOUBT ON RELIABILITY OF ON-SITE POWER SUPPLY CIRCUMSTANCES:
EDG FAILURE OCCURRED 2 1/2 HRS. INTO A 24-HOUR LOAD TEST OPERATOR SECURED EDG UNIT UPON HEARING " UNUSUAL" NOISES BACKGROUND:
UNIT HAD A NUMBER OF INADVERTENT STARTS WITHOUT PRELUBE SINCE LAST INSPECTION IN FEBRUARY 1985 3 0F 4 EDG's WERE INADVERTENTLY STARTED WITHOUT PRELUBE ON 11/10/85 EDG NOS. 11 AND 12 (DIV.1) HAD SIMILAR FAILURES IN JANUARY 1985 HOWEVER, LOWER BEARING HAS FAILED IN THIS EVENT, NO LOWER BEARING FAILURE OBSERVED PREVIOUSLY FOLLOWUP:
REGION III, NRR, FAA, AND DECO ARE SENDING SAME PERSONNEL WHO INVESTIGATED PREVIOUS FAILURES N0. 3 UPPER MAIN BEARING FAILED NO. 4 LOWER MAIN BEARING FAILED NO. 13 UPPER BEARING (THRUST) IS " DISTRESSED" DISASSEMBLY IS CONTINUING
ST, LUCIE UNIT 1 - INTERNALS LIFTING RIG FAILURE NOVEMBER 6, 1985 (S. LONG, IE)
PROBLEM:
WHILE REMOVING THE UPPER INTERNALS GUIDE STRUCTURE 1 0F 3 BOLTS CONNECTING THE STRUCTURE TO THE LIFTING RIG FAILED WITH THE STRUCTURE STILL OVER THE CORE SIGNIFICANCE:
THE 50 TON LOAD COULD FALL BACK INTO REACTOR VESSEL, POSSIBLY CONTACTING AND DAMAGING FUEL, RESULTING IN RELEASE OF RADI0 ACTIVE GASES TO THE CONTAINMENT CIRCUMSTANCES:
WHILE LIFTING INTERNALS, LIFT WAS STOPPED WHEN RIG WAS SEEN TO BE SLIGHTLY TILTED DYNAMIC FORCE FROM STOPPING LIFT CAUSED 1 0F 3 BOLTS ATTACHING RIG TO INTERNALS TO FAIL.
RIG CANTED -se N6" UP AND STRUCTURE s' N6" DOWN ATTEMPT WAS MADE TO LOWER INTERNALS TO INSTALLED POSITION, BUT LOAD CELLS INDICATED BINDING LICENSEE DECLARED AN UNUSUAL EVENT, ENHANCED CONTAIN-MENT INTEGRITY AND IMPLEMENTED PROCEDURES TO MONITOR LOAD STABILITY SECONDARY LIFTING RIG WAS DESIGNED, TESTED AND INSTALLED ASSEMBLY WAS JACKED LEVEL AND THEN MOVED TO ITS NORMAL POSITION IN REFUELING P0OL ON 11/9 FOLLOWUP:
UNDERWATER CAMERA SURVEY INDICATED THAT FAILED BOLT WAS ONLY INSERTED ABOUT THREE TURNS, AND STRIPPED DURING LIFT CE PROCEDURES FOR RIG ATTACHMENT INCLUDE VERIFICATION OF THREAD ENGAGEMENT; THIS WAS OMITTED FROM LICENSEE'S PROCEDURES KNOWN DAMAGE:
LIFTING RIG IS BENT.
SOME VESSEL GUIDE PINS ARE BENT, 3 INSTRUMENT THIMBLES ARE DAMAGED, NRR PROJECT MANAGER IS ON-SITE TO OBSERVE LICENSEE'S i

T BROWNS FERRY - 0FFSITE CONTAMINATION INCIDENT DURING EMERGENCY PLAN EXERCISE NOVEMBER 13, 1985 (F. KANTOR, IE)
PROBLEM:
CONTAMINATION OF INDIVIDUALS DURING EMERGENCY DRILL SAFETY SIGNIFICANCE:
PERSONNEL CONTAMINATION DISCUSSION:
TVA WAS SUPPORTING A STATE OF ALABAMA MEDICAL DRILL DURING AN EXERCISE OF THE BROWNS FERRY EMERGENCY PLAN.
SCENARIO CALLED FOR A MONITORING TEAM TO RESPOND TO A CONTAMINATED CASUALTY OFFSITE.
CONTAMINATION WAS SUPPOSED TO BE CONTAINED SOURCES.
A STATE OF ALABAMA EMPLOYEE WHO WAS ACTING AS AN EXERCISE CONTROLLER DRIPPED ABOUT ONE MILLICURIE OF LIQUID TECHNETIUM 99M ON THE BANDAGE OF A TVA EMPLOYEE WHO WAS PLAYING THE ROLE OF THE CASUALTY, ANOTHER MILLICURIE OF TE-99M WAS DRIPPED ON TO A LAB C0AT.
TE-99M IS A LOW ENERGY GAMMA EMITTER WITH A HALF-LIFE OF SIX HOURS THE SIMULATED CASUALTY ALONG WITH FOUR OTHER TVA EMPLOYEES ON THE RESPONSE TEAM BECAME CONTAMINATED IN THE COURSE OF HANDLING THE CASUALTY, THE INCIDENT TOOK PLACE ABOUT ONE AND A HALF MILES OFFSITE.
THE CONTAMINATION OCCURRED ABOUT 12:30 PM.
INDIVIDUALS RETURNED TO PLANT FOR DECONTAMINATION.
A NOTICE OF UNUSUAL EVENT WAS DECLARED AT 5:28 PM.
ONE INDIVIDUAL HAD CONTAMINATION TO 30,000 CPM ON HIS FACE AND 500,000 CPM ON ONE HAND, CONTAMINATION LEVELS RANGED FROM 800 TO 40,000 CPM ON THE OTHER FOUR INDIVIDUALS, THE ALABAMA STATE EMPLOYEE RECEIVED CONTAMINATION ON HIS SHOES.
A 200 SQUARE FOOT AREA 0F GROUND WAS ALSO CONTAMINATED.
SOME CONTAMINATION WAS INGESTED, INITIAL LICENSEE REPORT INDICATED ONE INDIVIDUAL RECEIVED ABOUT A 4% BODY BURDEN, TVA PERFORMED WB COUNTS AND IS COLLECTING URINE AND FECAL SAMPLES.
THE 200 SOUARE FOOT AREA WAS POSTED AS A CONTAMINATED AREA, FOLLOWUP:
TVA IS PLANNING TO MEET WITH THE STATE AND IS PREPARING AN INTERNAL REPORT.
NOT CONSIDERED A REPORTABLE EVENT, STATE OF ALABAMA IS PREPARING A REPORT.
ALABAMA IS AN AGREEMENT STATE.
A PREVIOUSLY SCHEDULED REVIEW 0F THEIR PROGRAM BY REGION II IS TO TAKE PLACE THIS WEEK, NO ADDITIONAL ACTIONS CONTEMPLATED AT THIS TIME, i

4 OTHER EVENT OF INTEREST HATCH UNIT 1 - CRACK IN THE DRYWELL INERTING AND PURGE LINE DECEMBER 15, 1984, (P, TREMBLAY, NRR) i PROBLEM:
CRACK IN N2 INJECTION LINE FOUND DURING ISI AFTER VISUAL AND LIMITED MT CONDUCTED IN RESPONSE TO GE SIL 402 SAFETY SIGNIFICANCE:
GENERIC IMPLICATIONS INSPECTIONS OF N2 INJECTION LINES CONDUCTED BY LICENSEES C0VERED BY GE SIL 402 MAY NOT HAVE BEEN ADEQUATE P0TENTIAL LOSS OF CONTAINMENT INTEGRITY DISCUSSION:
HATCH ATTRIBUTED EVENT TO GROWTH OF PRE-EXISTING WELD DEFECT GROWTH COULD HAVE BEEN INDUCED BY THERMAL STRESSES RESULTING FROM USING CAD SYSTEM IN ADDITION TO NORMAL INERTING SYSTEM
)
FOR START UP INERTING SINCE OUTSIDE AIR TEMPERATURE WAS 22* F DURING THE DAY AND THE CAD USES AN AMBIENT VAPORIZER, THERE WAS THE POSSIBILITY OF COLD NITROGEN INJECTION, THUS INDUCING THERMAL STRESSES NRC FOLLOWUP ACTION:
