  • @Nancy The generators also had water intakes to cool them and when they got trashed--the engines overheated very quickly and THAT was the kiss of death.
    by Jim 5/10/2011 9:40:48 PM

  • And it's unclear to me, to be more confusing, that they were ever started!!!
    by Jim 5/10/2011 9:42:05 PM

  • @dean I still see no data or evidence that plans and procedures went awry in the first 45 min after the quake. From all I've gleaned, the generators started after about 2 min of battery, and worked until the wave hit. Is there some different data anywhere?

  • Thats what I'm researching RBeaner. trying to sequence from T=0 out to T+90 minutes..

  • If we get a list of the plant power systems and them X those out that were lost on EQ and subsequent main steam valve closing which takes out the turbine along with the secondary turbine power for plant systems and instrumentation.. then we can begin to fully understand

  • @dean Helloall and dean... was loking at the dies conver were is the original info that your lookin at on them
    by fitter 5/10/2011 9:50:07 PM

  • what was it fitter?
    by dean 5/10/2011 9:50:48 PM

  • @ dean confused myself!!! were are the desiels located in the plant
    by fitter 5/10/2011 9:51:51 PM

  • www.nucleartourist.com some good start information
    by dean 5/10/2011 9:53:28 PM

  • some are in the basement and some out back @ fitter
    by dean 5/10/2011 9:53:52 PM

  • I have a photo of the emergency generator but it didn't give clues to the location.
    by Nancy 5/10/2011 9:54:31 PM

  • @dean The most aged ones. Greater metal fatigue, wear and tear on all components, etc. fared worst out of the Fukushima family. They're talkin bout startin up Dai-ini.

  • @RBeaner I got the premium so there are no ads anyway.
    by Jim 5/10/2011 9:56:13 PM

  • nancy.. i think the site layout what we have some where and cross sectional of the building shows the diesels in the basement.. and the one shows the elevation of the diesel as compared to the height of the tsunami which would have engulfed it
    by dean 5/10/2011 9:57:37 PM

  • @dean the bp for #1 list 2 ?otor - gen w/oil coolers there is also a momorail that runs vertical (from the looks- can't really understand what they are showing except it may be the transport system for equipt)
    by fitter 5/10/2011 9:58:00 PM

  • monorail probably for equipment removal
    by dean 5/10/2011 9:58:54 PM

  • check on page 12 of the shepard document nancy.. it shows the turbine room ..
    by dean 5/10/2011 10:00:04 PM

  • @dean these sit at elevn 18700 and up, I have not paid much attention to them, but assumed them to maybe be the energency generators.... as yes see your post below... but don't know if they are saying "motor gen.. in reference to the monorail... or these are energency gererators.... were are you picking up the info on the gereraters...???
    by fitter 5/10/2011 10:00:50 PM

  • I don't even think the STEAM DRIVEN FEED WATER pump worked
    by dean 5/10/2011 10:00:53 PM

  • R1's back up generator www.houseoffoust.com

    by Nancy via Houseoffoust 5/10/2011 10:01:08 PM

  • @dean That's probably what killed it.
    by Jim 5/10/2011 10:01:32 PM

  • R6's back up generator www.houseoffoust.com

    by Nancy via Houseoffoust 5/10/2011 10:02:08 PM

  • Another view of R6 back up generator www.houseoffoust.com

    by Nancy via Houseoffoust 5/10/2011 10:02:29 PM

  • typically a motor generator set is what is used for the exciter on the generator or and also is used in older units called MG sets
    by dean 5/10/2011 10:02:40 PM

  • R6 is the only unit that has an air cooled diesel emergency generator.. all others I assume are water cooled.. not sure where the water comes from yet tho.. but assumed is clean eater... from auxillary system
    by dean 5/10/2011 10:04:07 PM

  • @dean this would fall under "older" I believe.... were is the original info of two with one back up, is it a Tepco release or some other doc?
    by fitter 5/10/2011 10:04:48 PM

  • I have an email sent off the fairbanks diesels..
    by dean 5/10/2011 10:05:02 PM

  • I am going on the original plant @ jim not the newer designed ones... unless they upgraded diesel generators those old CLUNKER would be old schooll
    by dean 5/10/2011 10:05:48 PM

  • @dean the fairbanks is that a NPP or a gererator manufacturer? or something eklse
    by fitter 5/10/2011 10:06:01 PM

  • NPP
    by dean 5/10/2011 10:06:17 PM

  • i wish we had an electrical schematic of that place.. or at least of a plant like those in usa
    by dean 5/10/2011 10:06:56 PM

  • Diesel power to system safety equipment like critical water supply cooling instrumentation valves etc..
    by dean 5/10/2011 10:07:40 PM

  • @dean was doing a google on "explosions" today... guess what comes up three articles on camp perry and the practice runs for bin londin (only the locals were guessing libia 's guy
    by fitter 5/10/2011 10:07:48 PM

  • @dean Should be pretty standard. The interlock, etc.
    by Jim 5/10/2011 10:08:10 PM

  • ha ha.. wow @ fitter... your in the news
    by dean 5/10/2011 10:08:16 PM

  • Is Twitter not working ?
    by Veen Oui 5/10/2011 10:08:17 PM

  • yes Jim, I just think that with all the stuff happening due to unexpected consequences of the EQ then tranformer loss... the conditions worsens quicker that we think.. in the PCV but our research will hopefully prove out
    by dean 5/10/2011 10:09:28 PM

  • @dean with the exception of how the monarail is drawn in I would have for a first shot looked for them to be emergency generators.... I could (and have to myself) make an argument for them to be in the reactor build and not to be... or they could be the motors to sometheing totally different?
    by fitter 5/10/2011 10:10:54 PM

  • @dean My feeling is that the system was not robust enough to take the original outage--and she burnt up, basically before the big wave got there. It was all over but the cryin'.
    by Jim 5/10/2011 10:11:55 PM

  • @ fitter I believe from what I've read they are the emergency diesels.. if the mono rail runs accross the top that is what we used to pull the heads off the diesel for maintenance
    by dean 5/10/2011 10:12:02 PM

  • @dean please call purchasing and ask them for the model numbers
    by fitter 5/10/2011 10:12:05 PM

  • me too Jim... if the diesels would have been higher in the facility they would have functioned longer but with no cooling they really get hot fast..
    by dean 5/10/2011 10:13:05 PM

  • I will tomorrow fitter... trying to figure out the vintage of that year 1970.. .back in those day.. ENTERPRISE DIESELS were the main ones sold
    by dean 5/10/2011 10:13:41 PM

  • @dean that would make sense for the monorail. and it seemed out of place... it woulld go with the vintage gauges and pumps they have
    by fitter 5/10/2011 10:14:32 PM

  • another thing we'venot discussed is the plant air system and or instrument air systems.. all those big control valves have to have diaphram air and if it's lost valves begin to go to fail safe modes.
