RE: Feeder Status John, I just spoke w/ the supervisor in charge of the Isolation Condenser NDE and he expects the NDE report to be finalized by Wednesday. I will get a copy as soon as it comes in and send it your way.

RE: Feeder Status Thanks for the Feeder. Your timeliness astounds me!

RE: Feeder Status John, Attached is the feeder to the report. I will locate their formal documentation of the assessment. (Should they have formal documentation despite no issues?)

RE: Feeder Status John, Good Question. They accomplished that through a tag team effort between visual inspections and UT testing.

The visual inspection identified areas of corrosion/pitting that was suspect and was subsequently UT tested.

Only one area had been identified (NRC) that had four pits that were near min wall thickness, but were considered SAT. Additional UT testing was performed on 2 grids that were previously UT tested in 1 R19 (2002) and 1R16 (1996). Comparing the results, there was NO evidence of material loss of the Shell.

Therefore they concluded that there was no active corrosion/pitting occuring at a rate that would impact the functional capability of the Iso Cond.

RE: Feeder Status Thanks. just one question ... how did they evaluate the UT data to determine there was no pitting or excessive corrosion?

Feeder Status

John, I have completed writing up the feeder (B Iso Cond. NDE) for the report, however I am waiting on two small details (work order & date) for it to be done. I hope to forward the document to you early Monday morning.
