This preliminary notification constitutes EARLY notice of events of POSSIBLE safety or public interest significance. The information is as initially received without verification or evaluation, and is basically all that is known by the Region IV, Arlington, Texas, staff on this date. […]

At 10:44 a.m. (CDT), the licensee declared a Notification of Unusual Event because the failure of the supply breaker may have been caused by an explosion in the breaker cubicle. The event was terminated at 6:21 p.m. because the affected electrical bus was not energized and there was no other damage. The fire suppression system to ANO Unit 1 is shutdown due to the damage to the fire water system piping. Damaged portions of the ANO Unit 2 fire protection system have been isolated. Additional fire water pumps have been positioned to provide fire water if necessary. The licensee has established fire watches in the auxiliary buildings of both units. […]

    the gift that 'keeps on giving', just keeps getting 'better'…

    I'm starting to wonder if the "damage to fire suppression systems" is actually "damage to water systems which cool the actual units" are these plants really built with "water systems for fire suppression" or is that just a clever way of wording?

    • palisadesnpo

      The answer to your question is "no". The fire protection system is separate from the critical and non-critical service water systems.

      • palisadesnpo

        However, at least here we can cross-tie the fire protection system into the Critical Service Water headers…but we can not tie the Service Water System into the Fire Protection System…I'm sure it's the same at ANO.

    "…protected area."

    Protected from prying eyes? Protected from leaking the truth?

    • palisadesnpo

      "Protected Area" = the area that comprises the actual power plant (turbine building, containment, aux building, etc). The other areas of the plant are usually referred to as the "Owner Operated Area."

    When Fort Calhone was covered in water, a no fly zone was put in place by O, also the Red Cross took up with O like a dog in heat! If you check where each non profits spend the money they get, the Red Cross is on the botton of the list of waste, VFW & Salavation Army at the top going to those in need!DC is a total FUBAR as the world gets RADs by sea & air,plus the food & water not fit for anything!

      You said it, mister!
      no-fly zones will be more and more present in these situations… nothing to see here, folks! -except by Argus and its dronelettes!

      -TEPCO is right up there with a lot of other evil corps and tendrils of power on this God forsaken orb. I wish it were all good but people seemed tired before their years, thyroid problems in a lot of kids I read recently. Rather depressing.

      But ain't it grand now, really. Interesting times, and shifts.

        I remember that Leuren Moret said they have means to clean all this up after we all croak…maybe she was dreaming…or maybe there is the tech…she did work at Livermore…hmmm

        but I guess she's a kook, hunh, Wikipedia sez so.

        We all believe user-changeable Wiki now, don't we, as we do Snopes?

          Wikipedia has lots & lots of biased articles. Here are some:

          1.) Discussion of thorioum reactors (pro thorium reactors)
          2.) Chronic Lyme disease (Infectious Disesase Soc. of America, whose posture is it doesn't exist)
          3.) Discussion of dose threshold based on IAEA model of external dose exposre

          Check out a lot of the other nuclear-related articles on Wikipedia, and you'll find (if you are informed) they have a mostly pro-nuke bias.

          Snopes is notoroius for promoting urban legend, even though that's what it purports to inform about.
