MKENNARD OOM/OOC 10/1/2009 3:57:46 AM Reviewed the approved lifting paths for SGR 2250 crane with SGR (Larry McDougal). The plan does not permit lifts over the CI Tower DDEMONTFOR SOM part of the Intermediate building. The condition that was observed was an empty hook. Larry is following up with the crane operators to verify expectations with and wirhout loads.
10/1/2009 4:05:10 AM AI-504, CP-341 Time requirements for establishing pressure retaining vs. non-pressure retaining capability differ in the current revisions of churst 6 - VC CP-341 and AI-504. AI-504 is more conservative, requiring pressure retaining capability within 2.5 hours5.787037e-5 days <br />0.00139 hours <br />8.267196e-6 weeks <br />1.9025e-6 months <br />. All open plans were reviewed and verified that pressure retaining capability can be established within the currently required 2.5 hrs (shut-down condition 4). NCR 358254 has been written. Review of shut-down condition 5 is in progress.
10/1/2009 4:11:04 AM Update SW/RW clearance, IT identified that the source of the problem was an issue with one holder apparently accepting the same WOT MKENNARD 00M, O0C twice in the database and even though they had released the clearance, the database was maintaining them, unseen, as holding. A holder lock was applied to the clearance, IT forced the lift checklist to "distributed" and it was authorized and sent to the field. Dayshift needs to follow-up with IT to get a "backdoor back up" done to resolve the issue so the clearance can be closed when appropriate.
10/1/2009 4: 11:48 AM FAC engineer is needed at EPU station 145 Turbine Building A MSR to inspect as-found pipe that was removed by WO 1288186-28 bmarckese EOM/EOC Passing on to Greg Estep.
10/1/2009 4:18:05 AM Summary of the delays for meeting the 09/0/09 10:00 PM schedule milestone for completing move in of equipment through the equipment Rpontes SGRC/SGR hatch: -
Failed to meet the 10:00 PM milestone for containment move in (the actual finish was 02:35 AM). The main factors for the delay are the addition for four lead shielding boxes and the loss of RCCR-2 for the entire shift. The loss of RCCR-2 accounts for about 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> of the loss; the lead storage boxes account for about 1.5 hours5.787037e-5 days <br />0.00139 hours <br />8.267196e-6 weeks <br />1.9025e-6 months <br /> of the loss.

10/2/2009 8:49:09 AM SP-630 and Impact on Critical path: Completed evaluation of the possibility of moving SP-630, the HPI Full Flow Test, to the second RCS bwunderly SOM re-fill window. On review, the item is identified as a discovery item due to the potential to find a problem with an UPI pump and/or check valve. Given that the second refill window occurs at the end of November and the impact on critical path from this activity if performed at this time is not significant, SP-630 will not be moved.

The crosswalk RHarvey WCOM/CPM pull is resourced to the Refueling Team, but the rigging and pull can be completed by mechanics without diverting the Refueling Team from their critical path activities.

10/2/2009 9:31:59 PM (Ref. 10/2/09 09:31:58 log entry) The proper schedule ties have been added to the schedule to prevent C/Os 193578 and 195688 from being cdew OOM/OOC hung until after the completion of SP-630.

--pull SW pipes (CRDM cooling lines) from the vessel head structure
--one T-power transformer pick to support T-power
--RCRE- I steps removal from the vessel head structure (these are the steps from the catwalk to the head)

10/2/2009 10:20:00 PM SGR RB Coordinator (Dave English) reported that housekeeping in the RB--all levels-is very cluttered but acceptable and that no unsafe RHarvey WCOM/CPM conditions exist.
RB Coordinator further reported that he needs a 6-8-hour activity for the RCCR-l resource, starting with the opening of theequipment hatch, to remove containers from the RB. At present, there is no room on the 160-foot or 95-foot level to add more materiel.

10/7/2009 11:05:19 AM Held a meeting with MIMO (Dyer) and RP (Akins) to discuss the move out plan for the RB. Multiple boxes were deconned and wrapped RMELTON WCOM/CPM ahead of time to be ready to move out when the equipment hatch was reopened. During the FTC fill, particulate contamination is now above detectable limits on all of these previously cleaned boxes. The boxes will all need to be deconned again and in some cases re-wrapped. RP has assigned additional decon resources to this project to help get back on track with the schedule and RP supervision is stationed at the hatch.

10/7/2009 11:08:55 AM EC required for Erosion of CWP-1A liner and column kallen EOM/EOC The vendor repairing the liner and column is recommending that the eroded areas be repaired utilizing a sleeve. This has been discussed with the CR3 pump expert (Pat Hinman), who believes a sleeve is an appropriate repair. An EC will be required to install a sleeve in CWP-IA. WR#401758 initiated for the EC.
During disassembly of CWP-1A erosion was discovered between the liner (common called the turning vanes) and the interior column. The erosion occurred in the area of an 0-ring joint that provides the pressure boundary for the bearing cooling water. An O-ring is utilized in this location to allow vertical movement of the interior pump rotation element with respect to the pump casing.
The liner and column were sent to TAW for evaluation, after cleaning TAW is now recommending that the liner and the column be sleeved to restore the OEM fit. Additionally due to blistering and general coating failure the liner and the column will be recoated with ARC 855 (previously approved for use).
Cost to recoat the liner, column and perform the sleeve repair has been quoted at $88,785 with the majority of the cost attributed to the recoating ($64,164). It should be noted that the last time the turning vanes were coated was reported to be - 1985 time frame.
Replacement of the liner is not considered an option. A request for a quote and availability has been sent to the OEM, but based upon the cost of the discharge head I would anticipate cost in the $200,000-$300,000 range and a lead time of at least 26 weeks. Additionally once the liner was received it would have to be coatedat the same price as listed above.
Lead time for the coating and the sleeving is 14 days from the time of authorization with the majority ofthe lead time on material. I have received verbal approval to proceed with the recoating and have asked procurement to directed TAW to procure the required material while the site processes the EC. A review of material compatibility was conducted by Design engineering and their impression was that the proposed material was suitable to be used for a sleeve.
10/7/2009 11:11:27AM LESSONS LEARNED - FTC fill activities last night raised the particulate contamination levels in the RB. For the future, thought should be RMELTON WCOM/CPM given to reducing the fill rate, washing down of the FTC walls or some other method to reduce the level of contamination spread during refill.
10/7/2009 11:51:33 AM Notified by fuel handling team that PT-532 will not be completed until 1400, thus delaying the start of defueling until 1400. This is a thrn RMELTON WCOM/CPM hour delay on critical path. Notified the SOM (Dufner).

Subject:
CR3 SGR HYDRODEMOLITION EXPOSED CRACKS IN THE RB CONCRETE During hydrodemolition of the concrete containment wall, within the boundaries of the temporary access opening, cracks were exposed between adjacent hoop tendons. The cracks are generally in a vertical plane between the tendon sleeves and extend for an indeterminate length. It is possible the cracks were the result of hydrodemolition or just exposed by the hydrodemolition. The extent of the cracks cannot be established as the crack is exposed by the removal of the concrete which in turn prevents an assessment of the length of the crack. There is however, water leakage through cracks in the RB wall that would indicate the cracking extends beyond the area of the opening.
