Division of Safety Programs Office for Analysis and Evaluation of Operational Data FROM: Mark H. Williams, Chief' Trends and Patterns and Analysis Branch Office for Analysis and Evaluation of Operational Data alc 1
SUBJECT:
U.S. EXP(RIJNCE - RCP BEARING / IMPELLER FAILURES In response to your request related to recent foreign experience, we conducted a review of several data bases (SCSS, NPRDS, NPEARS, FEF and NUDOCS). We searched for events involving failures of reactor coolant pump impellers or in-water bearinc rings due to,-fagity welds. We found none, except for the one previously noted in Japan in9 9E4.. The review of U.S. experience included Bryon Jackson pumps in use as BWR and PWR reactor coolant pumps, and other manufacturer's pumps in use as domestic BWR reactor coolant recirculation pumps.
There have been a small number of events involving failed or damaged bearings and/or damaged impe11ers but none indicated that welding was.the cause. .Only five of the U.S. events mentioning impeller repair or replacement involved 4 Bryon Jackson pumps. These occurred in PWRs.
Both ROAB and TPAB staffs participated in the data search and review efforts.
If you need any additional information, please let me know. ,

f!P.C INFORMATION NOTICE NO. 89- : WELD FAILURES REPORTED IN A BYRON-JACKSON PUMP AND
/' ,/
ONE OF A SIMILAR DESIGN ,/
Addressees:
All holders of operating licenses or construction permits for nuclear power reactors.
Purpose:
l This Notice alerts addressees to informatio.n regarding foreign experience of weld failures in Byron-Jackson primary loop recirculation pump and another pump designed similarly. It is expected that recipients will review the information for applicability to their facilities and consider actions, as appropriate, to avoid similer problems. However, suggestions contained in this information notice do not constitute NRC requirements; therefore, no specific action or written response is required.
Description of Circumstances The information received by the f;RC staff is related to boiling water reactors; however, the nature of the failures were such as to potentially affect all pumps of similar design. The events brought to the staff's attention are as follows:
(a) In 1984, a foreign BWR experienced a failure in the attachment weld of a ring which surrounds the bearing housing component of a foreign pump very similar to Byron-Jackson recirculation pump. The operator performed repairs involving fillet welds applied at the crack loca-tions. During inspections last year (1988) cracks were found at the same locatior.s. The repair invcived applying butt welds at the cracks locations. -
(b) Similar problems were recently reported at another BWR plant. Signi-ficant vibration was observed during operation. The plant was inriediately shut down for inspection. It was found that the welds had failed entirely and that the ring had broken into three pieces; two of the pieces were relatively large and one of them was broken up into smaller pieces. One piece appeared to be attached to the upper impeller and one piece had travelled into the reactor vessel.
d The loose parts from the third piece were scattered in the recircula-tion piping. The manufacturer of this pump was not Byron-Jackson, but the staff believe that the design is similar to that of Byron-Jackson.
(c) As a result of the 1984 and 1988 incidents, BWRs in the foreign country began a program of inspection and repair using.similar methods. The unit which experienced the broken ring had not yet been inspected. As a result of the failure, other units of:similar power-level will either be shut down for immediate inspection, or be re-paired during the next scheduled inspections. Those of similar design but different power levels have adopted administrative procedures to ensure early detection of similar problems.
Ho specific action or written response is required by this information notice. If you have any questions abcut this matter, please contact one of the technical contacts listed below or the Regional Administrator of the- '
appropriate regional office.

_______________-______ _ __-_. J
l s E
HYDROSTATIC BEARINGS IN USA BWR - RECIRCULATION PUMPS o ORIGINAL ONE-PIECE STATIC CASTING WAS USED.
o LATER CONCEPTS USED TWO-PIECE CONSTRUCTION WITH A WELDED-ON BAFFLE PLATE.
o PUMP INTERNALS ARE NOT PRESSURE BOUNDARY PARTS OR SAFETY RELATED.
HENCE FABRICATION QUALITY, WHILE MANUFACTURED TO EXCELLENT STAN-DARDS, IT WAS NOT REQUIRED TO BE MADE PER ASME SECTION III. .
o MATERIAL AND FABRICATIONS WERE TO APPLICABLE SPECIFICATIONS.
o WELDING WAS PERFORMED BY ASME QUALIFIED WELDERS AND WORKM/NSHIP CHECKED BY COMPANY INSPECTORS.
o DUE TO AVAILABILITY OF LARGER -
CENTRIFUGAL CASTING MOLDS, THE LATEST DESIGNS CAN BE MADE WITH ONE-PIECE CENTRIFUGAL CASTINGS. l o A TAPERED BAFFLE PLATE, USED IN THE ONE-PIECE CASTING, FURTHER RAISES THE NATURAL FREQUENCY AWAY FROM POTENTIAL EXCITING FREQUENCIES.
o THIS LATTER CONCEPT IS NOW BEING
! UTILIZED FOR BEARING REPLACEMENTS.

)
Eackrround
]
A number of FWR reactor coolant pumps and BVR reactor recirculation pumps man-ufactured by the Byron-Jackson Company (B-J) have been disassembled and in-spected during the past few years because of the length of time the pumps have been in operation, ASME Section XI ISI requirements and some operational prob.
Iems. Thermal fatigue cracking has been observed in several pumps.
I CE Nuclear Energy issued RICSIL No. 003 on May 21, 1986, which, in part, ad-
{ dressed thermal fatigue cracking in pump shafts and covers. B-J issued a re- 1 i
isted advisory (Tech Note 8701-80-005) in January 1987. Both documents con- !
tained the conclusion that although the observed cracking was undesirable, it '
was considered to be relatively benign based on analyses and observations.
Cracks were expected to exhibit virtual arrest or show very small growth for depths exceeding 0.2 inches (shafts are 5 to 8 inches in diameter) . The Janu-ary 1987 B-J Tech Note recommended that utilities disassemble and inspect the pumps at the first convenient opportunity. Recent findings, however, indicate that the cracks may represent a threat to pump reliability.
Discussion Recent observations and measurements . , the pumps in operating installations show that some cracks have penetrated to depths greater than 0.3 inches in both shafts and covers. These depths are greater than previously anticipated based on the expected frequency of thermal cycling In the cover, cracks are axial and could be of sufficient depth to penetrate tne closed cooling water (CCV) circ.uit if cracks and flow passages are at corresponding azimuths. This represents a risk of contaminating a normally clean system and possibly sub-jecting it to higher pressures. No such occurrences have been reported.
In the shaft, some cracks chenge orientation from axial to circumferential.
This represents an increased risk of shaft failure under normal operating con-GENERAL @ ELECTRIC No wm OR REPRESENT ATION ExputESSED om IW8UED 45 MADE WITM RESPf CT To T4 ACCU 8ECY.

Y ditions if the cracks propagate to sufficient depth or under abnormal condi-
" tions if the shaft is subjected to increased dynamic loading as- could occur from cavitation or by a foreign object becoming lodged in the pump. No such failures have been reported in BVR pumps.
During the period in which these recent field observations were made. B-J per-formed an analysis of the crack initiation and growth mechanisms. This work included analysis of recent test data from a full scale operating temperature pump shaft and cover mock-up. The data verified previous conclusions that mixing cold seal purge flow with hot system water initiates cracks. The data also showed that previously unknown low frequency fluctuations occur. Shaft and cover crack growth analyses considering these low frequency fluctuation's support the field observations and indicate that such thermal cracks can pen-atrate to depths beyond the observed depth of approximately 0.3 inches, but at low propagation rates. Cracking in pumps without seal purge can occur but is expected to be less severe and to occur at a higher position on the shaft and cover.
Recomended Action CE recommends that BUR owners consider these findings and develop contingency g plans to prevent negative impact on power production and to minimize effects on outage maintenance activities. CE recommends that such contingency plans include the following.
- 1. Review pump and system design, period of operation and maintenance histo-ry. Correlate with other field experience to assess the potential impact on the pump or pumps in question. For pumps with a high potential for significant cracking, the following actions should be considered:
- Install shaft probes to monitor shaft vibration response to protect against consequential damage in the event crack propagation changes from thermally driven to mechanically driven.
- Monitor CCV effluent for contamination by reactor coolant to provide i early warning and to minimize contamination of external CCW system j and equipment in the event communication develops between these sys- '
tems.
- 2. Review ASME Section II ISI plans and commitments and establish plans which consider the recent findings described in this SIL. Schedule in-spections of pumps with greater than 80,000 hours0 days <br />0 hours <br />0 weeks <br />0 months <br /> of pump operation to detect cracks and implement corrective actions before axcessive crack growth occurs.

.u REACTOR'C00LANT PUMP SHAFT FAILURE AT CRYSTAL RIVER This is to discuss the applicability of NRC IE Information Notice No. 86-19 )
(Reactor Coolant Pump Shaft Failure at Crystal River dated March 21, 1986) to BVR Reactor Recirculation Pumps manufactured by Byron-Jackson (BJ) Company based on analyses and examinations completed since March 21.
Information Notice 86-19 provided a summary of information available in March 1986 regarding the Crystal River Reactor Coolant Pump shaft failure and I identified other potentially affected facilities. BWR facilities were not mentioned. However, there are a number of BJ BWR Reactor Recirculation Pumps in service whidh are of the same general design. General Electric has been supporting Floiida Power Corporation on the shaft failure problem and has in parallel evaluated available information for potential BWR pump impact. l l
Cracking attributed to two different mechanisms has ken observed at Crystal l River: 1) a mechanical fatigue shaf t failurt ond 2) shallow thermal fatigue
~
cracking of the pump abaft and cover. Information available at this writing indicates the following to be the most significant findings * '

o Something changed which caused the cristing crack to grow causing shaft failure in a relatively short time period; thousands of hours. ;
o Impeller-to-shaf t attachment bolts and drive pins had failed (combination of stress corrosion and fatigue) resulting in a loss of positive impeller i to shaft attachment. l l
o At this time, the evidence suggests the cause of shaf t failure to be the ;
pre-existing crack which propagated under increased loading resulting l from failure of impeller attachment bolting. This has not been !
l confirmed; evaluation is in progress.
Thermal Tatigue . .
1 o Shallow thermal crheking was observed in the thermal barrier region of the pump shaf t and the adjacent region of the pump cover; caused by ,
mixing of cool seni injection flow with hot reactor water behind the pump !
impeller.
o Similar thermal cracking was not observed on the shaft at the failure ;
initiating crack. 'It-does not appear that the shaf t failure is related j to the thermal cracking. !
\
BVR Recirculation Pumps are of the same general design but differ in a number -
1 of areas. Relative to the above, the most significant difference in the BWR ]
pu=ps is in the impeller-to-shaft attachment where either a full penetration i weldment or a nut which is locked by a pinned, reverse-thread cap screw is I employed. GE considers these arrangements to provide a more positive impeller-to-shaft attachment and therefore less likely to induce increased
- loading which, which when combined with some other shaft defect, could lead to shaft failure. l With regard to the shallow shaft and cover thermal fatigue cracking observed at Crystal River in the thermal barrier exit region, similar observations have been reported at three BWRs facilities. In these cases the cracks have either been removed or returned to' service "as-is" based on evaluations performed by the plant owners. Based on. analysis GE concluded that in the absence of other 1 mechanical driving mechanisms such thermal cracks are expected to arrest or show very small growth for depths exceeding .2 inches. This is consistent with available BWR field experience and the Crystal River observations and analysis. ;
1 N
RICSIL No. UU3 In summary, the shaft failure at Crystal River is believed to be the result of
. previously dormant crack of unkncvn origin, which propagated with increased loads from a degraded impeller-to-shaf t attachment. There is no reason to believe similar conditions exist in BWR pumps though the possibility cannot be !
absolutely ruled out. Thernal fatigue cracking has been observed in both !
Crystal River and BWR BJ pumps and while not desirable does not appear to pose !
I a threat to pump reliability.

BINGHAM RECIRCULATION PUMP SHAFT CRACKING
Background
SIL No. 459, titled " Byron-Jackson Recirculation Pump Shaft & Cover Cracking",
issued December 15, 1987, described instances of BWR recirculation pump shaf t cracking in Byron-Jackson pumps. GE recently became aware of cracking discov-ered in the shafts of two Bingham recirculation pumps.
The purpose of this RICSIL is to inform BWR owners of this finding, particu-larly those whose BWRs use cold water recirculation pump seal purge in either Byron-Jackson or Bingham pumps.
Discussion In July'1988, GE received a report of the inspection of the pump shafts of the A and B Bingham recirculation system pumps at a BWR/5 located in the United States. These shafts had operated 27,000 and 21,000 hot hours respectively and were inspected following recirculation pump repairs and wear ring replace-ment. .
Liquid penetrant examinations of the A and B pump shafts revealed numerous ax-ial cracks at an elevation just above the top of the impeller keyway and spac-ed approximately equally around the entire shaft circumference. Ultrasonic examination of the A pump shaf t showed 20 to 30 cracks ranging from 0.20- to L

RICSIL No. 028 0.50-inch long with a maximum reported depth of 0.15-inch. The B pump shaft .
had 70 to 80 cracks 0.50- to 1.0-inch long with a 0.34-inch reported maxitmm depth. The cracks are at the elevation at which seal purge water mixes s th reactor coolant under a protective thermal bushing.
Although there are design and construction differences between Bingham and By-ron-Jackson pumps, both mix seal purge vster with reactor coolant. This has the potential to initiate thermal cracking in the areas of the shaf ts where the cracks were detected. In both instances, thermal stresses are the sus-pected cause of crack initiation. The Bingham pump shaft cracks, which are not significantly different from the cracks observed earlier in the Byron-Jackson pump shafts, are not a threat to safety, but probably will affect maintenance and inspection intervals.
Crack initiation and growth depend upon thermal and mechanical loading. GE is studying the rate of crack growth and orientation of c' rack propagation to de -
velop recommendations for corrective actions. GE will inform BWR owners of additional information on this subject as it becomes available and requests that owners inform GE of the results of pump examinations. Such information will be used to characterize crack growth behavior and can be used to develop inspection and maintenance recommendations for other pumps.

BYRON-JACKSON RECIRCULATION PUMP SHAFT AND HEAT EXCHANGER CRACKING Backaround The purpose of this RICSIL is to inform BWR owners that cracking was discover-ed recently in the shaf t and heat exchanger of a Byron-Jackson (B-J) recircu-lation pump of a design used in some BWR/6 plants. The internal construction of this pump design is different from that of the earlier B-J pump 6esign. In the never B-J pump, a pertion of the shaft is hollow and, therefore, is dif-ferent from the pumps discussed in SIL 459 and RICSIL 028.
SIL 459, titled " Byron-Jackson Recirculation Pump Shaft & Cover Cracking", is-sued December 15, 1987, described the instances of pump shaft and cover crack-ing in the earlier classes of B-J BWR recirculation pumps. RICSIL 028, titled
" Bingham Recirculation Pump Shaft Cracking", issued September 7, 1988, de-scribed the occurrence of shaft cracking in Bingham BWR recirculation pumps.
Discussion In August 1988, an inspection was performed on the shaft and heat exchanger, as well as other pressure boundary components, of a B-J recirculation pump in-stalled in a BWR/6 located outside the United States. This pump is equipped with a shell-type internal heat exchanger with a rotating baffle. It is a more recent B-J pump design than those equipped with the drilled hole type of internal heat exchanger. .

( i RICSIL No. 029 The pump in which shaft and heat exchanger cracking occurred had operated for approximately 30,000 hours0 days <br />0 hours <br />0 weeks <br />0 months <br /> and was inspected concurrently with other mainte-nance activities performed on the pump. Numerous crack indications were de-tected by liquid penetrant examinations of the shaft and heat exchanger.
Crack depths were measured using other techniques.
Cracking in the shaft occurred in the smooth, tapered region and in an adja-cent region which has square grooves for flow restriction. Both regions are near the location at which cold seal purge injection water mixes with rsactor coolant. The liquid penetrant test in the smooth portion revealed a random ;
pattern of cracks within a 2.5-inch length of the shaft, extending completely 1 around the shaft circumference, with axial cracks extending into the threaded )
portion of the shaft. Metal was removed in steps to a depth of 0.09-inch at i
~
which depth the cracks, including circumferential cracks, were still present. .
No additional metal was removed from the shaft because this depth was consid- '
ered sufficient to warrant replacement of the partially hollow shaft.
Crr. eking in the inside diameter of the heat exchanger was observed at the same ,
elevation as the shaft cracking and was oriented axially. About 80 cracks 1 were found with lengths up to 5.5 inches measured from the lower extremity of I the heat exchanger bore. The cracks were detected by liquid penetrant testing I and crack depths up to 0.150-inch were measured by the electrical potential drop technique. Cracks at the inside diameter of the heat exchanger are of
. concern because this member is the pressure boundary between the reactor cool- )
ant and the plant closed cooling water system, which is normally clean and op- '
erates at a lower pressure than the reactor coolant. l The cracks described in this RICSIL are not a threat to safety. However, they l probably will affect pump maintenance and inspection intervals. i Crack initiation and growth depend upon thermal and mechanical loading. Both GE and B-J are studying crack growth and orientation of crack propagation to develop recommendations for corrective action. Destructive examination of the pump shaft is planned. GE will inform BWR owners of additional information concerning this subject as it becomes available.
GE requests that BWR owners inform GE of the results of pump examinations.
Such information will be used to characterize crack growth behavior and to de-velop inspection and maintenance recommendations for other pumps.

f RECIRCULATION PUMP EYDR0 STATIC BEARING FLANGE FAILURE ]
k- Background Instances of recirculation pump hydrostatic bearing baffle plate cracking have recently been reported to GE Nuclear Energy. These instances have all occur-red in Byron Jackson design pumps operating in BWRs located outside the United States. The pu=ps in question were manufactured both by Byron Jackson and a licensee of Byron Jackson. In one case, f ailure occurred resulting in inter- l l
nal damage to the pump and a number of loose parts were swept downstream to l the jet pumps in the reactor vessel. This failure was preceded by a high vi-bration alarm. In the other cases, the onset of failure was observ 2d during l
routine pump inspection and maintenance; corrective action was implemented and l
the pumps were returned to service.
The purpose of this RICSIL is to inform BWR owners of these events and to pro-vide additional techni, cal details as known to GE Nuclear Energy.
Discussion The By on Jackson pump design used in BWR/3, 4, 5 and 6 employs an internal hydrostatic bearing to support pump shaft The radial loads. The hydrostatic bear-differential head of the pump ing is located just above the impeller.
provides hydrostatic pressurization of the bearing. With the exception of two BWR/6s located in the U.S. and one BWR/6 located outside the U.S., this hydro-static bearing is designed with a non-rotating bearing baffle plate to mini-GENERAL h ELECTRIC
f RICSIL 038 mize turbulence in the bearing orifices. Many plants have a welded design wherein this baffle plate is attached to the outside of the hydrostatic bear x ing structure with two fillet welds. Circumferential cracking has been ob- ^ \
served in and around these fillet welds. .
It is important to note that all of the instances of cracking, including the most recent pump failure. involved Byron Jackson design pumps with large ir-peller diameters of approximately 39 1/2 inches, but not all larger diameter l pumps have experienced cracking. (The baffle plate diameter is slightly smal- '
l ler than the impeller diameter). No failure (or cracking) of the baffle plate welds have been reported for pumps with impeller diameters of 35 inches or less. All BWRs in the U.S. with this pump design have impeller diameters of 35 inches or less. In addition, many plants with the welded (smaller dia-meter) design have a significantly greater number of operating hours than the pumps (located elsewhere) with cracked baffle plates. For this reason, GE Nu- ,
clear Energy does not believe that art immediate shutdown and pump inspection ,
is necessary for BWRs in the U.S. However, because of the limited number of !
pumps disassembled and inspected, BWR owners should incorporate baffle plate inspection into their next pump inservice inspection, maintenance and overhaul plan. Individually, GE will contact owners of BWRs located outside the U. S.
whose plants have larger diameter impellers to provide plant unique recommend-ations.
GE is studying the crack mechanism with Byron Jackson with the goal of evalu- ;
ating the cause. GE will inform BWR owners of additional information on this j subject as it becomer available. .
l GE requests that BWR owners inform GE of the results of any pump examinations. i Such inspection data vill be used to characterize the cracking mechanism and l can be used to develop inspection and maintenance recommendations for other utilities.

r EQUIPMENT Byron Jackson reactor coolant and recirculation pumps have an L integral thermal barrier in the pump cover. The barrier consists of an inner bore with multiple spiral grooves which form a close running clearance with the pump shaft and act as a flow restrictor. A water jacket, formed by a series of interconnected verticat holes drilled in the cover, surrounds the cover bore and uses component cooling water to remove neat from this cover region.
I ouring n-service inspection (ist) activities, thermat fatigue cracks !
SITUATION have been ooserved in a one-inch band at the bottom of the therma! ,
barner. Crack initiation is due to mixing of the cold mechanical seal I injection water, which flows down the shaft annulus, with the hot system water at the bottom of the theimal barner. Byron Jackson !
Technical Service Bulletin No. 8701-80-005 discusses the mechanisms of this fatigue mode; reports that observed cracks in the grooved cover bore have an axial orientation; and states that !
analyses prec ct crack arrest at a depth of approximately 0.15 inch.
Subsequent inspection of the thermal barrier region of a BWR cover has found cracks with a depth of 0.310 inch. On this cover, anc on a second cover for which depth measurements are not available, crack propagation extended upward into the cover bore to an e!evation corncident wrth the bottom of the water jacket hetes. Ligament I
thickness between the cover bore and water jacket holes on this unit is 0.280 inch (see : illustration on reverse side).

In this Event, the com-ponent cooling water system could be subjected to reactor system pressures and radio 6ctive contamination.

- 5. ~~. ~ S EQUIPMENT Byrm .sacxson reactor ewiant and recircuietion pump covers have tnermai barriers which inci';3e an inner bore with multiple spiral grooves. These grooves form a close running clearance with opposed spiral grooves on the ,
pump shaft and act as a flow restrictor. Pressurized system water is cooled l as it passes upward through the barrier annulus, unless the pump is suppliec l with a seat injection system. In this case, cold injection water flows down the j annulus. 1 SITUATION Th'rm*' '*t'Su' cr*ek5 occur on th' $urfac' of th' Shatt ia and bo* the 1 cover thermal barrier. This situation is desenbed in Technical Service i Bulletins Nos. 8701-80-005 and 8701-80-006, which state that axial thermal ;
cracks will either be arrested completely or their growth rate will be slow.
Crack geometries subsequently measured at one BWR 4 plant showed that depths are greater than the arrest depth predicted by earlier analysis. Data j trom this unit also show that crack orientation changes from axial to cir.
cumferential when crack growth extends into ?he shaf: base materiat.
EVALUATION For pumps with seal injection systems cracks are observed on the shaft in a region at the bottom of the thermal bstrier where cold injection water mixes with hot reactor system water. In units without seal injection systems, thermal ;
cracking is caused by the hot reactor coolant flowing up the shaft annulus and mixing with the cocied water in the seat cavity. On these pumps, thermal ,
cracks occur ort the shaft at the top of the thermal barrier. In either mixing '
region, dynamic pressure vanations drive the hot reactor water into and out of the thermal barrier annulus, exposing the metal surfaces to variations in temperature and resultant thermal stresses.
Previous crack growth predictions were based on parametric fracture mechanics studies when minimal measured physical parameters _and_fjaO verification data were available. Crack depth meas:,:rarnents'have now beer.

On the shaft, liquid penetrant testing revealed a crazed crack pattern extend-A a.e ing 3600 around the smooth surface of the transition region. Distinct axial x

ential cracks had depths in excess of 0.09 inch as determined by sequential machnnng and hquid penetrant operations.
~ On the heat exchanger bore, approximately 80 axial (vertical) cracks were observed uniformly spaced around the smooth bore of the heat exchanger above the skirt. These cracks ertended upward into the grooved region.
Crack depths up to 0.150 inch were measured by the potential drop method.

% TECHNICAL with a thermal barrier in the pump cover. The barrier consists of an inner DISCUSSION. bore with muitipie spiral grooves which form a ciose running ciearane. wiin the pump shaft and act as a flow restrictor. A water Jacket, formed by a -
series of interconnected vertical holes drilled in the cover, surrounds the cover bore and uses component cooling water to remove heat from this cover region.
A mechanical shaft seat cartridge is installed in the cover immediately above the thermal barrier. Clean make up water is injected into the seal cartridge from an external source at flow rates less than 10 gpm and at temperatures between 1101258F. Approximately one gallon of the seal hjection water flows upwards through the seals for cooling,lubricaton, flushing, and staging purposes. The bulk of the injected water flows. downward through the cover
- thermal barrier and mixes with system waterg ,
in the cover bore and that portion of theMp shaft containing spiral grooves, the surface thermal stresses are primarily in the hoop direction and the orientation of the cracks is axial. On the smomh portion of the shaft, below the thermal barrier, stresses are both axial and circumferential. Hence cracks are in a random or "tunlo-back" pattom with a predominantly 458 .
orientation. The severity of the cracks is determined tey the interacting effects .
of the rate and temperature of sealinjection flow, the presence of pressure oscillations due to rMft orbit, the axial location of the cover water jacket, and the mechanical conditon of the cover anct phaft surfacus. For this ro6 son,
~
thermal cracking is not observed in at; pumps with seal injection flow.
For the pump shaft, calculations show that axial cracks in the grooved '
portion will propagate slowly or may be arrested completely. Field data generally support these predictens. However, for any particular unit, crack growth could be more rapid if sufficient mechanical loads are present. In the smootn surface regions, the observed random pattern indicates that more sonous circumferential cracks also exist. In either case, the thermal cracks could ultimately result in shaft failure and pump damage.
Calculations for the pump covers indicate that cracks will generally be arrested within a depth of about 0.15 inch. ISI examinstens have shown the cracks to be located in a region below ttpoiseer water Jacket. However, under extreme mixing conditons, crack Isutisten and propagation might occur in the water jacket region and leakage of primary coolant into the com- y ponent cooling water system could occur. ,

PROBLEM g tion (ISI) at one PWR nuclear generating facility revealed axial thermal cracu on the pump shaft. No indi, ations had been observed under visual inspec- j tion. The cracks were confined to a region of the shaft corresponding to the top 1% inches of the thermal barrier.
4 CAUSE Thermal cracking is caused by the mixing of the tot reactor coolant flowing up the shaft annulus with the cooling water circulating in the seal cavity. In the mixing region at the top et the thermal barrier, the rotating shaft surface is exposed to rapWy varying water temperatures which cause alternating thermal stresses. The frequency of this dynamic action can vary between !
t Hz to 2ti Hz. Thus, a large number of stress cycles;can occur in a short operating time and fatigue cracking of the material can result, vein The existence and propagation of thermal cracks in pump shafting cannot be RECOMMENDATION rehably predicted from operating histories or from accumulated operating times. Thus, the following actions are recommended:
l C Disassemble and dye penetrant inspect the shaft during ISI or at the next convenient opportunity.
O Report inspectior: details to the Pump Division. Recommendations, including component replacement, will be proed6d based on spectic location, depth, and orientation of the observed cracking.
Corrective action is not recommended prior to Pump Division review to assure that benefits from industry experience with similar equipment can be realized.
The Pump Division is also addressing this problem as part of a product im-(
l provement program and will include features in an up graded cover design which minimize or eliminate exposure of the shaft and cover to the high cycle therma! mixing action.

, ABSTRACT POWER LEVEL - 035%. ON .1/28/BB AT 7:12 P.M. , A REACTOR SCRAM OCCURRF.D DURING STARTUP OF THE 1B REACTOR RECIRCULATION (RR) PUMP DUE TO AVERAGE POWER RANGE MONITOR (APRM) HIGH FLUX. DURING THE PUMP STARTUP 1 SEQUENCE, THE 1B REACTOR RECIRCULATION MOTOR GENERATOR (RRMG) SPEED COMTROL SYSTEM MALFUNCTIONED, RESULTING IN A CORE FLOW INCREASE GREATER THAN EXPECTED WHEN THE IB RECIRCULATION LOOP DISCHARGE VALVE AUTOMATICALLY J0GGED OPEN. CONSEQUENTLY, REACTOR POWER INCREASED TO
~
THE APRM HIGH FLUX SCRAM SETTING (APPROXIMATELY 66% POWER) FOR THE EXISTING REACTOR FLOW CONDITION. DURING THE ENSUING REACTOR VESSEL WATER LEVEL TRANSIENT, WATER LEVEL DECREASED TO THE POINT WHERE -l ACTUATION OF GROUPS 2, 3, AND 6 ISOLATIONS OCCURRED. ADDITIONALLY.
UPON TRANSFER OF 4160V AC POWER, BOTH DIESEL. GENERATORS AUTOMATICALLY STARTED. AT THE TIME OF THIS EVENT, THE PLANT WAS IN OPERATION AT APPROXIMATELY 35% POWER (275 MWE). THE FLOW CONTROL SYSTEM.
MALFUNCTION OLCURRED AS A RESULT OF A LOCKING SCREW, USED TD. SECURE A -
DISC THAT ACTUATES HIGH AND LOW TRAVEL STOPS, WHICH HAD CHOOSEN AND VIBRATED OFF. THE DISC DROPPED INTO THE LOW LIMIT SWITCH AND, DUE TO VVS ACTUATION, SCOOP TUBE DRIVE IN THE LOWER DIRECTION WAS ELECTRICALLY STOPPED. THEREFORE, THE EXPECTED RUNBACK OF THE RRMS TO l MINIMUM SPEED FOLLOWING PUMP BREAKAWAY WAS PREVENTED.

ABSTRACT FDWER LEVEL - 064%. ON 06/27/85 AT APPROXIMATELY 1320 CDT, WHILE PLANT PERSONNEL WERE PREPARING TO INCREASE LDAD ON THE UNIT THE "1C" START-UP TRANSFORMER (SUT) SHORTED TO GROUND CAUSING LOSS OF POWER TO THE "A" AND "B" 4160 VOLT BUSSES. THIS RESULTED IN IDSS OF POWER TO THE " A AND "B" REACTOR RECIRCULATION PUMPS. WHILE PLANT PERSONNEL WERE ATI'EMPTING TO MANUALLY SCRM THE UNIT (REQUIRED BY TECH SPECS SECTION 3.6.J.1), AN AUTOMATIC SCRAM FROM THE NEUTRON MONITORING SYSTEM (I.E., IDSS OF RECIRCULATION PUMPS RESULTED IN AN APRM FLDW BIAS SCRAM SIGNAL) WAS RECEIVED. THE EVENT RESULTED FROM NON-LICENSED PLANT PERSONNEL CLOSING THE INCORRECT FIRE PRMECTION DELUGE VALVE DIAPHRAGM CHAMBER WATER SUPPLY VALVE. THIS CAUSED THE FIRE PROTECTION WATER SYSTEM TO ACTUATE AND SPRAY THE "1C" SUT, RESULTING IN A PHASF-TO-GROUND FAULT TRIP ON THE "1C" SUT. THE FIRE PROTECTION DELUGE VALVE DIAPHRAGM CHAMBER WATER SUPPLY VALVES WERE LABELED CORRECTLY AND THE MISALIGNED DELUGE SPRAY N0ZZLE WAS REALIGNED. POWER WAS RESTORED TO THE "1C" SVT AND THE "A" AND "B" 4160 VOLT BUSSES. BOTH RECIRCULATION PUMPS WERE RETURNED TO SERVICE ON 06/28/85 AT APPROXIMATELY 1320 cur.
