Description:
Unable to reassemble E-l22B, "B"TBCCW Heat Exchanger Channel Head end due to leakage at Salt Service Water (SSW) isolation valves. Suspect MO-3805 and / or 29-HO-3833 are leaking by.
(This was problem was originally identified on 2/26/02 (90100 hrs.) First attempt on 2/26/02 (90430 hrs. appeared to stop leakage but the drain path was not checked prior to manipulations so it was unclear whether it was the valve(s) or tide level.
This was during Low Tide.
No further manipulations were conducted and flow was again present at 1000 hrs. during High tide. Attempts to stop SSW leakage during the dayshift through the Low Tide were also unsuccessful.
Lost production time / manhours and increased equipment out of service time (>24 hrs.) due to this issue.
Also, if isolation is obtained during a Low Tide, reassembly will require going through two (2) additional Low Tides due to piping configuration and adequate time for reassembly of Channel Head and Cover onto E-122B.
Immediate Action
Description:
Notified OPS and attempted to stop SSW flow but unsuccessful.
Re-attempt(s) to stop leakage will be perfomed during Low Tide.
Suggested Action
Description:
NESG to review history of maintenance conducted on these valves and forward recommentation for repair / replacement of these valves.

Enftygy CORRECTIVE ACTION CR-PNP-2002-09283 Complete isolation of E-122B for maintenance was primarily affected by leakage past the seat of MO-3805 ("B" TBCCW/SSW Discharge Valve). This leakage was previously identified on 5/7/00 under MR10001079 by the SSW System Engineer during troubleshooting for macrofouling concerns of E-209A, E-209B, E-122A & E-122B Heat Exchangers. A TIC was submitted by the SSW System Engineer to recommend replacement of this valve during RF0#13. The TIC was later rejected and the valve was not replaced. The SSW System "B" Loop was drained during RF0#13 a replacement valve was on-hand and this valve could have been replaced without impacting the Outage Schedule.
MR02101255 - PERFORM 2.2.31.1, EVALUATED LEAKAGE PAST MO-3805 - This M R was closed on 1/30/02 -
Leakage was found to be acceptable - Operations performing leak verification indicated by hearing a vacuum vs. experiencing a fluid leak, and determined that this leakage would not affect the isolation of E-122B for maintenance.
MR10001079 - VALVE LEAKS BY ITS SEAT - This MR was later cancelled on 1/29/02. It was cancelled due to evaluation results of MR02101255 above CANCEL, VALVE WAS TESTED UNDER MR02101255 BY O P S WHICH DETERMINED/VERIFIED LEAKAGE TO BE ACCEPTABLE.

M R #02104125 written on 2/28/02 to identify seat leakage and the difficulty obtaining isolations of E-122B.
MO-3805 LEAKED BY IT'S SEAT WITH IT TAKEN UP TIGHT MANUALLY WITH HANDWHEEL SEAT LEAKAGE This MR has been approved by Outage Management to replace this leaking valve in RF0#14.

can be worked at the same time that the valve is being replaced. This task and the replacement of the valve can be worked together and the valve seat limit stops can be set with the valve out of the adjacent piping spools. This work will assist the craft in verifying that the limit stops are properly set and that the seat did not travel beyond its normally closed position.
This valve as last replaced on 11/1/94 under MR19300991. It is possible that the limit stops were improperly set and the valve disc traveled beyond its closed position. If this was the case, damage to the Rubber Lined body (seat) could have occurred. Inspection of the existing valve when it is removed should indicate this condition.
In Summary: Replacement of this valve (MO-3805) during RF0#14 should address future on-line isolations of SSW to E-122B "B"TBCCW Leakage past this valve will not affect its safety function to go to 10% open durning in an acident condition.
This CA has been presented to CRG for closure to MR02104125. CRG has approved this CA to be closed to MR02104125.
No further action is required.
