SAPN 50336850 - Elastomer Hoses Attachments: SAPN 50336850.pdf Importance: High
- Greg, Attached is the updated elastomer hoses notification SAPN 50336850. PMs have been created for periodic replacement of hoses at a 10 year frequency. The hoses will be short lived based on the period replacements and therefore have no impact to the LRA. SAPN 50336850 is now closed.

Funct. Loc: DC-0-04 U0 SYS 04 TURBINE STEAM SUPPLY Reported By: PNS3 Philippe R. Soenen Rpt By Work Ctr: PL Contact Info: PNS3 Philippe R. Soenen 805/544-6984 Created On: 23 Aug 10 16:25 Planner Group:
Main Wrk Ctr: EMS-005 Kubran Krystina - KHK3 PROBLEM DESCRIPTION 08/23/2010 16:25:46 Jana M. Orlando (JMSO) Phone 805/545-3126 08/19/2010 16:55:41 Philippe R. Soenen (PNS3) Phone 805/781-9782 During the an NRC insepction walkdown elastomer hoses were identified in the compressed air system for the portion of the system that is in scope for license renewal. The material type of elastomer had previously not been identified as within license renewal scope for system 25. The question was raised on how these elastomer hoses would be aging managed for the period of extended operation.
The license renewal project team has determined that these elastomer hoses are within the scope of license renewal and would have to be aging managed by an aging management program or periodically replaced. If periodically replaced the hoses would be screened out from requiring aging management per 10 CFR 54.
The project recommends the creation of a PM that would periodically replace these hoses and eliminate the requirement to apply an aging management program to these hoses.
The final determination on periodically replacing these hoses or commiting to applying an aging management program will need to be communicated to the NRC as part of the License Renewal review process.

A task will be initiated off this notification to track the sumittal to the NRC.
08/23/2010 16:25:40 Jana M. Orlando (JMSO) Phone 805/545-3126 The issue/event documented on this notification was reviewed by the Notification Review Team (NRT) and determined to be the indicated significance level per OM7.ID1, Attachment 1, Category 18.1. If additional information is discovered that would affect the significance level determination, contact a member of the NRT or e-mail DCPP NRT Members.
DN closed to DA.
09/15/2010 13:50:58 Michael D. Wright (MDW4) Phone 805/545-4067 Re-routed to System Engineer:
Action:
Work with PM group to create a PM for hose replacements on a 10 yr frequency for air lines associated with the backup air bottles to the 10% ADV's.
If there is any question an the scope of the air lines, contact the License renewal project.
10/19/2010 03:13:41 Krystyna H. Kubran (KHK3) Phone 805/545-3231 Orders for STP I-4-pcv19/20/21/22 have a step to inspect air supply hoses and:
A. Replace air supply hoses and fittings IAW MP I-2.24-3 as needed.
B. Perform any dedication activities as required.
C. Perform pressure check and verify no leaks IAW MP I-2.24-4 This may be expanded to include all elastomer hoses associated with each valve.

Description:
LR Question on Sys 25 Elastomer Hoses Order:
The request was for the elastomer hoses from the backup air bottles to the PCV's. The request was to create a PM to replace, not inspect, at a 10 year frequency. By "replacing" versus "inspecting" we do not have to develop an aging management program. Again, these are the hoses at the bottles.
Please review this with MSE Manager prior to closing.
10/26/2010 15:29:06 Krystyna H. Kubran (KHK3) Phone 805/545-3231 System engineer is requesting that SAPOs for STP I-4-pcv19/20/21/22 have Operation 0100 updated to reflect that ALL elastomer hoses are to be visually checked.
Current Operation description:
