THE OPERATING REACTORS EVENTS MEETING l February 9, 1988 - MEETING 88-06 1
l On February 9,1988 an Operating Reactors Events meeting (88-06) was held to i brief senior managers from NRR, RES, AE00 and Regional Offices on events which I occurred since our last meeting on February 2, 1988. The list of attendees is included as Enclosure 1.
The events discussed and the significant elements of tMse events are presented in Enclosure 2. The Enclosure 3 presents a tabulation of long-term followup assignments to be completed and a sumary of reactor scrams. No significant events were identified for input to NRC's performance indicator program.

V0GTLE UNIT 1 GATE VALVE PRESSURE LOCKING PROBLEMS l FEBRUARY 3, 1988 PROBLEM BOTH RHR CROSS-CONNECT TIE VALVES FAILED TO OPEN DURING SURVEILLANCE TESTING.
CAUSE THE VALVES FAILED DUE TO PRESSURE LOCKING OF THE VALVE DISKS BY THERMAL EXPANSION OF WATER TRAPPED BETWEEN THE DISKS.
SIGNIFICANCE DOUBLE DISK WEDGE-TYPE GATE VALVES ARE USED EXTENSIVELY THROUGHOUT SAFETY RELATED SYSTEMS AND MAY BE REQUIRED TO OPEN DURING OR FOLLOWING DESIGN BASIS EVENTS.
DISCUSSION o FEBRUARY 3, 1988 - TWO RHR CROSS-CONNECT VALVES FAILED TO OPEN DUE TO PRESSURE LOCKING 0F THE VALVE DISKS, THE MOTOR OPERATORS BURNED-UP WHILE ATTEMPTING TO OPEN THE VALVES DURING SURVEILLANCE TESTING.
o THIS PROBLEM IDENTIFIED IN 1977 BY NRC IE CIRCULAR 77-05, "LIQUID ENTRAPMENT IN VALVE BONNETS."
o 1981, IE INFORMATION NOTICE 81-31, "FAILURE OF SI VALVES TO OPERATE AGAINST DIFFERENTIAL PRESSURE."
o 1981, GE SIL LETTER #368, "RECIRCULATION DISCHARGE ISOLATION VALVE LOCKING." i o 1983, INP0 FOREIGN REACTOR EXPERIENCE REPORT, "FAILURE OF RHR SUCTION VALVES." NO SUGGESTED PECOMMENDATIONS TO ADDRESS DOMESTIC PROBLEMS.
o JULY 1984, AE0D REPORT ON PRESSURE LOCKING OF FLEXIBLE DISK WEDGE- l TYPE GATE VALVES. I o AE0D AND IE AGREED TO ALLOW INP0 TO ADDRESS THIS PROBLEM. j o DECEMBER 1984, INP0 REPORT (SOER 84-07) ON PRESSURE LOCKING OF l FLEXIBLE DISK WEDGE-TYPE GATE VALVES.
CONTACT: J. THOMPSON
REFERENCE:
50.72# 11404
7 o INP0 SOER 84-7 DID NOT ADDRESS NORMALLY OPEN VALVES WHICH CLOSE AND CANNOT BE RE0PENED.
o THIS PROBLEM APPEARS TO BE LIMITED TO VALVES SUBJECTED TO PRESSilRE/ TEMPERATURE CHANGES (E.G., RHR (PWR/BWR).
FOLLOWUP o INP0 TEAM DISPATCHED TO V0GTLE SITE FOR EVENT ASSESSMENT AND TO GATHER NEW INFORMATION FOR ISSUANCE OF A SUPPLEMENT TO THE 1984 INP0 SOER.
o LICENSEE PERFORMING SAFETY ANALYSIS TO DETERMINE OTHER AFFECTED VALVES.
o V0GTLE MODIFICATION TO THE RHR VALVES WILL BE TO DRILL A PRESSURE RELIEF H0LE IN VALVE DISK ON THE DOWNSTREAM SIDE.
o EAB CONSIDERING INFORMATION NOTICE ON V0GTLE VALVE FAILURES DEPENDING ON THE ADEQUACY OF THE UPDATED INP0 SOER.

, CATAWBA 2 FOREIGN OBJECTS IN STEAM-GENERATOR JANUARY 22, 1988
. PROBLEM DEBRIS FOUND ON THE SECONDARY SIDE OF STEAM GENERATORS HAS APPARENTLY CAUSED TUBE THINNING.
CAUSE INADEQUATE QA.
SIGNIFICANCE o POTENTIAL FOR TUBE FAILURES.
o BREAKDOWN IN QA APPARENTLY AT WESTINGHOUSE AND DUKE.
DISCUSSION o DURING 8/87, EDDY CURRENT (EC) TESTING OF SGs A AND D INDICATED NO AN0MALIES.
O DURING 12/87, EC TESTING OF SGs B AND C DISCLOSED WORN TUBE IN SG B.
o VISUAL INSPECTION DISCLOSED PRESENCE OF 3 JACKING STUDS (2-3" LONG BY 2-1/4" IN DIAMETER) ON TUBE SHEET BETWEEN TUBE WRAPPER AND BUNDLE.
o STUDS WERE APPARENTLY EXTRAS INADVERTENTLY LEFT IN SGs DURING FABRICATION.
o SUBSEQUENTLY, VISUAL INSPECTION OF SGs A AND D DISCLOSED THE PRESENCE OF A CARBON STEEL BLOCK (1-1/2" X 2" X 3") AND A SEMICIRCULAR SLIVER OF STEEL 8" X 3/8" THICK.
o IN SGs A AND D, PLUGGING OF 1 TUBE EACH WAS REQUIRED BECAUSE OF TUBE WALL WEAR.
o ADDITIONAL DEBRIS FOUND INCLUDES SMALL GAUGE WIRE, 1 NAIL, A PIECE OF WELD ROD, WELD SLAG, AND ROCKS.
O SOME OF THE METAL PIECES FOUND ARE BELIEVED TO BE FIT-UP PIECES.
o PREVIOUS EC TEST DATA WERE REVIEWED FOR SGs A AND D AND A BAD TUBE WAS IDENTIFIED.
o EC TESTING OF 100% OF PERIPHERAL TUBES IN SGs A AND D WAS PERFCRMED.
FOLLOWUP o LICENSEE AND WESTINGHOUSE ARE DETERMINING CAUSE.
o OEAB INTENDS TO DRAFT AN INFORMATION NOTICE, o OEAB WILL REQUEST STATUS OF UNIT 1 SGs, CONTACT: R. WOODRUFF
