    nuclear plants depend on adequate flows of offsite
    power to operate safety systems if needed? GOOD READ

    When specialists do a Seismic PRA what is typically found to be the dominant source of risk is a combination of the following:

    An earthquake damages incoming power lines by failing the ceramic insulators associated with high voltage power lines.
    Onsite emergency diesels fail due to provide power (typical causes include anchorage of diesel engine coolers, disruption of fuel oil supplies, etc)
    Inability to restore power from downed transmission lines or bring in a large portable generator eventually results in loss of battery power, instrumentation, and the ability to cool the reactor.

  • I wonder if they inspected the ceramic insulators at those plants where EQ's occured recently ..

  • interesting @elaine.. doing calorimetrics must be done to bring the plants in synch,,, bryon runing higher that it could be is not good...

  • not sure what to make of this doc about chemical testing re byron docs.google.com
    by elainekirk 2/1/2012 1:28:09 AM

  • @elainekirk I think it is testing particulate vs. a filtration system but not sure why the details on chemical whatnot.
    by lillymunster 2/1/2012 1:32:30 AM

  • ooo seismic data !!!!!!! search byron there are a few covered pbadupws.nrc.gov
    omg they even show all reactor wall damage f'in ell am I imagining it??
    look at drawing 6-10
    by elainekirk 2/1/2012 1:37:27 AM

  • @elainekirk at least Byron doesn't have a fault line running directly under it. That seems to have been typical in the 1970's

    The issues listed on North Anna in that are um. eep.
    by lillymunster 2/1/2012 1:46:44 AM

  • @lillymunster exactly so eeepish

  • Byron not being on a fault line has a laundry list of seismic concerns listed. There must be soil issues.
    by lillymunster 2/1/2012 1:52:08 AM

  • yeah and why hasnt power been restored rather long delay with no 'we expect' announcements
    by elainekirk 2/1/2012 1:57:23 AM

  • @elainekirk i found that odd also. Remember N. Anna the operator and NRC were quicker to give an assessment and time to recover at least power.
    by lillymunster 2/1/2012 2:11:05 AM

  • @lillymunster really odd

  • Byron Update! An insulator failed and FELL OFF causing the outage. Tuesday at earliest for repair lucian.uchicago.edu

  • @lillymunster so they are on emergency for another week?

  • More problems at Byron

    NRC spokeswoman Viktoria Mitlyng says some water pumps at the Byron Generating Station switched off when the Unit 2 reactor lost power Monday, then came back on without being manually reset. www.carmitimes.com

  • French Report Faults Indecision on Nuclear Industry
    www.nytimes.com
    The court, an independent agency perhaps analogous to the U.S. Congressional Budget Office, noted that in a practical sense the kind of build-up in new generating capacity necessary to replace the aging reactor fleet was essentially “impossible.”
    by lillymunster 2/1/2012 2:34:19 AM

  • @Lily, regarding your comment on the fault lines: This has been on my mind a lot as well. Seems many plants are located on fault lines all around the world. Makes me wonder if they were just looking for cheap land.
    by Lurking 2/1/2012 2:36:54 AM

  • @Lurking some were supposedly "unknown" at the time of construction but found later as seismic science advances. Then there are many that were "unknown" until someone fessed up that yea, the execs knew the fault lines were there.
    by lillymunster 2/1/2012 2:43:41 AM

  • @Lily, I agree, the execs knew they were there. I bet it was just cheap land.
    by Lurking 2/1/2012 2:58:49 AM

  • @Lurking plants built in the 70's are now in the middle of suburbs, not in the middle of nowhere. The safety by distance has been voided.
    by lillymunster 2/1/2012 3:01:24 AM

  • @ Lily, I have thought about the burbs moving in as well. Still have many friends and family way too close to San Onofre for my comfort.

    by Lurking 2/1/2012 4:26:25 AM

  • info from OC Register www.ocregister.com "Unplanned shutdown of San Onofre reactor"
    The unit 3 reactor at the San Onofre nuclear plant began an unplanned, precautionary shutdown Tuesday evening after sensors picked up a possible leak in one of the reactor's steam generator tubes.
