San Onofre (SONGS)

Wait isn't this the leak that Meter Swangin swore was normal? I bet the Feds are just probing to see how big a reward they should give to San Onofre!

Normal?  Not Unit 3.   

Unit 2 normal.  Plugged 12 tubes of 9737 each SG.  Ready to start up.

Unit 3:  problem.  Manufacturing defect.  Tubes rubbing.  In situ testing at up to 5000 psi of most suspect tubes failed a few.  Be down for several months.

Proud of the company.  No rush....safety first.

[Fermi2]

YOU claimed Unit 3 was normal.

[Safety Matt]

...so something vibrates a little, tubes rub, wear in spots.  Not at all unusual, although disappointing. 

Normal?  Not Unit 3.

Guess those tubes shoulda studied harder...

Seven tubes fail test at Calif. San Onofre 3 reactor

March 16 | Fri Mar 16, 2012 2:29pm EDT

March 16 (Reuters) - A total of seven steam generator tubes have now failed pressure tests at the 1,080-megawatt San Onofre Unit 3 nuclear reactor, which has been shut since late January due to a small radioactive gas leak, Southern California Edison said

Who made the SG's?

[MeterSwangin]

Who made the SG's?

Mitsubishi Heavy Industries, Kobe Japan.

Unit 3 SGs had a big problem...channelheads "delaminated" when SGs undergoing final pressure testing.  MHI cut off the channelheads to fix, then welded SGs back together.  Appears tube bundles tweaked a bit in the process.  Few tubes now wearing funny.

Worried looking Japanese joined by worried looking Waterford folks.  Waterford replacement SGs delaminated with cut/weld repair by different Mfr.

Addressing it the nuke way:  slow,deliberate, safety first, full disclosure.  "No timeline on safety."  Davis-Besse lesson...........

[MeterSwangin]

YOU claimed Unit 3 was normal.

We were told some tube wear was normal for new replacement SGs.  Turns out, after 6 weeks of testing, this tube wear aint normal at all.

AREVA guys tell me lots more testing planned.  Be nice and I'll keep you posted.

Unit 2 normal.  Plugged 12 tubes of 9737 each SG.  Ready to start up.

Not true (see story below). Unit 2 plugged 192 tubes.  Per Edison spokeswoman "But neither reactor will be restarted until all testing and assessments have been completed."

You might want to check the validity of your quoted source before you throw it out!

"One tube tested, it did not fail"!  "192 tubes plugged"!  The 'sciencedude' doesn't seem to understand WTFHITA!

Quote was in reference to SONGS 2, where only one tube was required to be "in-situ" hydro tested.  The 192 plugged tubes statement was also in reference to SONGS 2 (some were probably plugged due to meeting the plugging criteria, some as a preventative measure).  Based on discussions with SG engineering people I know at SONGS, sciencedude is correct.

Ok true. I admit I slept like a baby

I'm old. Woke up every 2 hours to pee!

[MeterSwangin]

One tube in situ tested Unit 2.  Did not fail.  Plugged 12 tubes with indications.  Plugged more with no problems to take out of service near suspected source of rubbing...a small retainer bar.

Several tubes tested Unit 3.  Had greater than 90% thru-wall wear so were expected to fail.  Did fail.  Triggers NRC notice and augmented inspections.

Expecting to start Unit 2 for summer must-run period.  News articles say western U.S. might have serious power shortage issues this summer as economy heats up..............

Actually, the Required is more like: Scram (due to 82 gpd leakrate), Mode 6, open up the manways, and then smear and frisk. Partial credit
