- Below summary is how to get in on conference - 245 to 400pmn SThe conference is set up for most of the afternoon but I would like to actually start at 245pm due to Tim O'hara and my availability and Tim Luppold needs to go on to another conference at 330, 1 want the Component S
Integrity view of the the FEA done first, iI tried to summarize the TS discussion from yesterday below - I will also this email on a appointment in outlook calendars for the key internal stakeholders.
Purpose is to discussion completion status and major issues associated with documents to date related to operability and structural integrity issues related to the degraded piping found at Unit 1 and implications to Unit 2,
Success is mutual understanding for each document:
-discuss any immediiate safety concerns
- give completion status or additional needs like* the document should not be draft along with next steps
- discuss major concerns related to operability and structural integrity of each unit's AFW headers past or future as applicable
-summarize other notes or issues that you feel should be addressed - ensure we have an email on details.
Lupold - Finite Element Analysis on the replaced section of No. 14 and No. 12 headers in the yard are.

- i) Lupold -Technical Evaluation supporting the reduction in design pressure to 1275psi\\tJf.

- document decision from yesterday
-Failure to do code pressure drop test for buried pipe violates TS 4.0.5
-which leads to TS 4.0.1 failure to do ST so take action of the applicable LCO
-(AND can't take exception of TS 4.0.3 since test was never done - see Ennis email form yesterday),
,* -leads to TS 3.4.11 on Class 3 structural integrity section c - restore structural integrity or isolate component
-(evaluation of structural integrity may be acceptable without code relief assuming test and inspections will be done in a reasonable time frame)
-LCO for AFW TS 3.7.1.2 (3 operable flow paths) not entered - data from Jan 2010 indicates the ability to deliver required flow through headers as noted in risk assessment - basis for 1.25 year exposure time on risk
"*t assessment assuming failed headers Nos. 24 and 22.
Cahill -Risk Asssessment completed per TS 4,0.3 - might not have been needed but it may have.informational value

All - summary evaluation of structural integrity for Unit 2.
All-longer term
