H-I -FD-CEE-1879 Hope Creek HPCI Exhaust Piping Supports 12'; 2/04 Analysis of Reported Damage in RFI2 Revision 0 I Revision Sumimary Revision Date Descri tion and Reason for Change 0 12/10/04 Original Issue 2 Purpose On November 1, 2004, with the plant in Mode 5 for RF 12, tandem snubbers on the HPCI turbine exhaust piping failed during dynamic testing. Subsequent inspections of the HPCI system resulted in several observations. These observations were thought to confirm a damaging water hammer in HPCI exhaust piping. The tandem snubber condition was documented in Notification 20209622. This evaluation was prepared to assess if the observed conditions were caused by a water hammer in the HPCI exhaust piping system. 3 Scope The scope of this evaluation is the tandem snubber failure documented in notification 20209622 and the observations from the concomitant inspections on the HPCI exhaust line from the HPCI turbine to the torus penetration number P-201 (1-FD-006-HBB-20) and the vacuum breaker line from its attachment to the HPCI exhaust line to torus penetration P-204 (1-FD-006-HBB-3, 1-FD-008-HBB-3, and 1-FD-008-HBB-8. 4 Discussion

4.1 Background

The HPCI System is designed to pump water through the 'A' Core Spray spargers and the 'A' Feedwater header. The primary purpose of HPCI is to maintain Reactor Pressure Vessel (RPV) inventory for small breaks that do not de-pressurize the RPV. The HPCI System may also be used for RPV pressure control. Finally the System may be used for RPV inventory control following reactor isolation and a coincident failure of the non-ECCS RCIC system. Exhaust steam from the HPCI turbine is discharged below the surface of the suppression pool. A drain pot at the low point in the exhaust line collects moisture present in the steam. Collected moisture is discharged through an orifice to the HPCI barometric condenser. A system of vacuum relief valves and isolation valves is installed as a vacuum breaker line, which cormects the free space in the suppression chamber with the HPCI turbine exhaust line.

H-1-FD-CEE-1 879 Hope Creek HPCI Exhaust Piping Supports Analysis of Reported Damage in RFl2 12/12/04 Revision 0 mitigates the effects of water from the suppression pool being drawn into the HPCI turbine exhaust line. Table 4-1 lists the major components in the HPCI turbine exhaust line. The pipe lines are ASME Code Section III, Class 2. Piping struts, hydraulic snubbers, frames, and spring hangers support the piping. Table 4-2 lists the pipe supports of the lines in this evaluation. The isometric drawings for these lines are References 7.3 and 7.4. Per the IS snubber inspection program the inspection scope was expanded to other snubbers in the area. The scope was further expanded at the request of Design Engineering. In the end all snubbers and hangers were inspected on both the HPCI and RCIC turbine steam lines. Non-destructive NDE was also conducted on numerous welds as requested by Design Engineering (See Section 4.3). Table 4-1 Major Components in the HPCI Steam Exhaust Line Component Description HPCI Turbine Exhaust Drain Pot Collects condensate from turbine exhaust and turbine draining to barometric condenser Exhaust Line Rupture Disks Prevents overpressure protection of turbine casing and exhaust line Exhaust Line Check Valve (V004) Provide backflow isolation of the exhaust line from the suppression pool HPCI Turbine Exhaust Line Isolation Valve Isolates turbine exhaust line from the (HV-F071) suppression pool HPCI Turbine Exhaust Outboard Vacuum Isolates the torus atmosphere from the HPCI Breaker Isolation Valve (HV-F075) turbine exhaust line following a breach of the HPCI steam piping concurrent with high drywell pressure.

All welds were found satisfactory. 5 Support Observation Analysis 5.1 Tandem snubber test failure (I -P-FD-006-H ISA and B) The snubbers on the HPCI steam side piping systems are manufactured by Lisega. The snubbers are Lisega Part Number3O72. The tandem pair of HPCI snubbers (HIFD P-FD-006-HO0 5(A)&(B)) were being testing in compliance with the IST Snubber program per procedures SH.RA-ST.ZZ-0105(Q) and NC.DE-TS.ZZ-3067(Q) to verify Technical Specification 3/4.7.5 requirements. For the A snubber, initial testing for running drag was successful with 1/2" per minute rate. The tension lock up and bleed test was then performed. The snubber locked at 107% of rated load. The compression lock up and bleed test reached 60.8 %, and then the load dropped. Upon opening the snubber the distance tube and circlip were both deformed. The B snubber failed similarly with tension reaching 106% and compression 10.3%. The same components were damaged. An outline drawing and parts list for this snubber is in Attachment C. These snubbers are on their fifth refueling cycle and this snubber pair has not been tested since the design change from PSA mechanical type snubber to Lisega type snubbers in RF07. Past IST visual examinations (completed every 36 months and last performed in RF1O) have not revealed any degradation at this location. No visual degradation was noted during this inspection until physically tested. Page 6 of 9

H-l-FD-CEE-1 879 Hope Creek HPCI Exhaust Piping Supports 12/12/04 Analysis of Reported Damage in RF12 Revisiun 0 An apparent cause evaluation is being performed in Condition Report 70042341. This apparent cause will address possible water hammer modes and snubber failure assessment. The failed snubbers were returned to Lisega for evaluation and testing. Based on Lisega's examination it appears that the reservoir poppet valve was stuck open. This allows the reservoir to fill solid, fully compressing the reservoir spring and loading the distance ring and circlip. This is a compression loading of the snubber. Lisega has postulated that the snubbers would have been able to perform in a Seismic event and that the testing method on the snubber test machine exaggerated the poppet problem to damage the reservoir snap ring. Lisega is continuing their analysis and have not yet provided a written report. 5.2 Snubber as found setting not per design (I-P-FD-006-H22) Design detail drawing (Ref. 7.7) calls for the snubber setting to be 2 1/2", the as found setting for this outage was 5 3/8". This would be a significant change in the position of the snubber. Additional research of inspection notes by the snubber program manager show the condition has existed since the Lisega snubber was installed. This will be documented in his disposition of the NUCR associated with 20210035. Confirming this are the engineering walkdowns that carefully examined the verticality of the valve this snubber supports. Also the pipe clamps on either side of the valve were examined. There is no misalignment of the struts on these clamps and no scratch marks on the pipe at the clamps. The clear conclusion is that the pipe and valve did not rotate. The engineering walkdown observations are included in Attachment A. 5.3 Strut misaligned 15 to 20 degrees (1-P-FD-006-H04) Walkdown by engineering indicated less than 4 degree from vertical. This offset is within construction tolerence. Originator of notification has been requested to complete Condition Report confirming he agrees with engineering assessment. 5.4 Snubber Extension Tube Bent (I-P-FD-006-H20) Although a bowed support is a possible indicator of overload due to an axial load. A lateral load causing the deformation appears more likely since adjacent supports and components show no evidence of high load, the snubber tested satisfactory in RF12 expanded inspection, and the extension tube is 7/8" diameter - a susceptible to damage size if climbed on or hung from. This is a congested area with frequent valve work-5.5 Spring Can Movement larger than design (I-P-FD-006-HOl) Scraping between the indicator and can indicates that movement from 1/4 inch to 3/8 inch may have occurred. The design movement on the hanger drawing is 1/8 inch per the hanger drawing. Paint scrapes between the indicator and can are not a reliable indicator of piping movement. This hanger is adjacent to the HPCI turbine. The indication could be a result of normal operational loads from the turbine operation, disassembly of pipe support during maintenance, original installation of hanger, or disconnecting the HPCI piping from the turbine exhaust. This observation cannot be used to support or refute the possibility of water hammer in the system. Page 7 of 9

H-l-FD-CEE-l 879 Hope Creek HPCI Exhaust Piping Supports 12/12/04 Analysis of Reported Damage in RF12 Revision 0 6 Conclusions and Recommendations Evaluation of the snubber failures and inspection observations reveals there is no conclusive evidence that a waterhammer event has occurred in the HPCI Turbine Exhaust line to the Torus. All inspections point to a structurally sound piping system that has not experienced loads that would displace the line, rotate pipe clamps, damage component, or overstress the piping. The following recommendations should be implemented to complete the validation of the conclusion of this evaluation

1.

Lisega Inc.'s final failure analysis report must be received and confinned as matching their preliminary input.

Purpose:

Inspect the HPCI Turbine Exhaust Line from HPCI turbine to the suppression pool for evidence that would support or refute the reported damage attributed to waterhammer. Approach: Using the piping isometrics, detail pipe support drawings, and ISI observations as a guide, a hand over hand inspection of the piping was performed. Attributes that were carefully observed were pipe alignment, valve alignment, claunp alignment, scratches on piping that would indicate clamp and frame rotation or axial movement, position of insulation, crimping on metal insulation at tight clearance locations, attachment point wear mark, and attached cables and small piping. Results: Observations are in order of inspection from turbine to torus HPCI Turbine Room Hangers in the HPCI turbine room showed no evidence of large deflection. Hanger l-P-FD-006-H01 had less than 4 degree angle to vertical. Scaffolding was available at wall penetration. The adjacent support, 1-P-FD-006-H08 is a box frame that showed no scratches or other evidence of large deflections. The pipe as it penetrated the concrete wall was not concentric with the pipe sleeve. It was slightly north of center. All supports were satisfactory. Torus Room Torus support lower and upper pins near the HPCI exhaust torus penetration were inspected for signs of rotation. There was no evidence of pin extension, light surface corrosion at pin/support interface was unbroken, and dust on pins was undisturbed. The torus room concrete wall to HPCI piping bellows cover was slightly askew, only the outer convolution of the bellows could be seen, The pipe appears to have been installed a bit north of wall penetration sleeve center. Inspection of the bellows was not possible with cover plate in place. The first horizontal from wall penetration and vertical runs showed no evidence of movement. Two struts, l-P-FD-006-H 1 and H12 that provide lateral restraint on the vertical riser were aligned and showed no evidence of rotation. The next horizontal HPCI exhaust line run includes the exhaust line check valve and the isolation valve. There are 5 supports on this horizontal run. Most insulation was blanket and it allowed for pull back and close pipe inspection. Scaffold provided very good access for this length of pipe. Strut H13 adjacent to angle was straight and aligned. The H1I5 with tandem struts was reinstalled Page AI of A2

H-I -FD-CEE-I 879 Hope Creek HPC1 Exhaust Piping Supports 12/12/04 Analysis of Reported Damage in RFI2 Revision 0 with new snubbers. The frame, lugs, and pipe were examined for evidence of movement or loading. The support frame and lugs had no paint scratches, wear marks, dents, or other signs of loading that would indicate high load. The piping had no scrape or paint marks at the interface with the pipe. The struts on either side of the exhaust isolation valve were aligned correctly. Close cxamination of the clamp/pipe interface confirmed no rotation of the clamps. These clamps are very close to the isolation valve. The attachment cables to the valve operator were taut but showed no signs of stress. The valve orientation was vertical. Snubber H22, attached to the operator, was aligned. There was no evidence that this valve rotated due to piping movement that could account for the change in cold setting. Additionally the insulation on the pipe was in contact with an adjacent structure and showed no damage of evidence of large deflection The last pipe segments of the exhaust pipe to torus penetration were all satisfactory. The vacuum breaker line is a 3" line that includes two check valves, two motor operated valves, and a manual valve. The strut reported as bowed was not installed. The location of the strut was observed to be in a location that could be used for climbing. Page A2 of A2
