Japan Earthquake

Japan Earthquake | Page 1876

in europe, there is always the discussion about planes hitting the nukes. when i understand it right, the fuku reactors (and all the others without dome and with spent fuel pools next to the reactors) are not in any way safe against plane crashs. i wonder that there is no discussion about it.

true Edano
by dean 7/9/2011 11:08:40 PM

but.. if the plane crashed through the outer shell.. it probably wouldn't crash through the concrete containment.. as if that mattered because the spent fuel pool is vulnerable
by dean 7/9/2011 11:09:19 PM

@dean i guess a destroyed pool is disaster enough - and there will be no way to get near the reactor anymore. and you can hardly remote control them.
by Edano 7/9/2011 11:10:50 PM

right Edano... I suspose a 747 directly hitting a fuku.. plant if fully loaded with fuel .. would be one **** of a mess
by dean 7/9/2011 11:12:29 PM

@dean i fear even a bigger cessna could do it if it hits the sfp wall directly.
by Edano 7/9/2011 11:15:06 PM

true

my dinner ready.. be back
by dean 7/9/2011 11:15:38 PM

Dean, so Cooper has a square building like Fuku but that building is likely heavy duty concrete rather than a blow away thin shell? IIRC some of the other US reactors I have seen have that round silo type heavy concrete, I am guessing that is in place of the concrete bulb type used at Fuku? So cooper's steel containment is just an inner layer and the thick concrete is just a separate device doubling as outer building?

COOPER

3. Vent Valves
Vent valves were added to CS A upstream of the flow element (FE), and to emergency
condensate storage tank (ECST) outlet pipe diameter enlargement to HPCI suction and upstream
of the HPCI FE. CS B does not have a similar configuration, and a vent valve was not needed.
For RHR trains A and B steam condensing mode piping, the RV was removed and replaced with
an elbow and vent valve assembly. A vent valve was added to the RHR Train A Service Water
(SW) injection connection.
As an enhancement for HPCI restoration after maintenance, vent valves were added to the lube
oil cooler and two other unvented high points in the auxiliary cooling subsystem.
4. Procedures
The appropriate fill-and-vent and surveillance procedures were revised to add the use of the new
vent valves. As described in NPPD's response to Question 3 of the NRC Request for Additional
Information (Reference 6), NPPD also revised the appropriate fill-and-vent and surveillance
procedures for UT at specific locations. The procedures were also revised to provide specific
instructions for documenting in the Corrective Action Program (CAP) gas voids or gas entrained
water identified during venting

@lillymunster from a statical point of view, i would guess the domes should be more resistant to a plenty of posibilities...
by Edano 7/9/2011 11:20:00 PM

reading what lilly and elaine put up
by dean 7/9/2011 11:23:02 PM

@lilly.. I would have to confirm that about cooper ,,, having a heavy square containment isn't as strong as the dome type.. will study it..
by dean 7/9/2011 11:26:04 PM

will research it to be sure..

Petition Filed to Shut Down Cooper Nuclear Power Plant
Brownville, Neb.
An Enforcement Petition has been filed with the U.S. Nuclear Regulatory Commission (NRC) requesting that the agency issue a Confirmatory Order requiring the shut-down of the Cooper Nuclear Station operated by Nebraska Public District.
by dean 7/9/2011 11:29:48 PM

@dean will see if I can dig up more images also
by lillymunster 7/9/2011 11:29:53 PM

ok.. I will return in a bit

RE the Radioactive Truck Video - the company website ASSOCIATED COURIERS INC

Initially, Associated Couriers was more involved with the delivery of bank work. As business increased, more vehicles were added to the fleet and additional warehouse and office space was needed. The business moved into its current location in 1983, which has allowed the business to grow to its present status. As bank work became more competitive and less profitable, Mr. Anderson saw the increased need for specialized carriers of nuclear medicines to hospitals and pharmacies.

Over the years, the business has grown and adapted its equipment and operations to meet the specific needs of its nuclear medicine customers. Some of the products delivered for these customers contain radioisotopes and are referred to as radiopharmaceuticals. This branch of medicine uses radiation to provide imaging information about the functioning of a person's specific organs. Given the nature of these products, most are time-sensitive and have a determined "half life." It is because of the characteristics and sensitivity of these types of products that make a specialized carrier like Associated Couriers the perfect choice.

Then on the SERVICES page:

Our drivers are licensed in compliance with the Department of Transportation Regulations and specially trained to handle your Class 7 radioactive products.
Most units have additional lead shielding installed to minimize possible exposure for handling radioactive products. (note "Most" units...implying not "All"!)

@ms in la mostly and any radiation poses no immediate risk to health why is there no regulation over the movement of this stuff
by elainekirk 7/9/2011 11:48:23 PM

Good evening everyone! @ms in la , usually radiopharmaceuticals are packaged in shielded containers (small glass vials packaged in roughly two inch-diameter pieces of lead pipe with a lid and a bottom). Generators, that is columns containing mother nuclides that produce short-lived daughters that are rinsed off the column through openings, are the size of a small bucket, also heavily shielded in lead. The shipments are sent by plane quite frequently and the packaging is supposed to withstand major impact. The guys that Majj found out about must have had some incident causing a spill.
by Peter Melzer 7/9/2011 11:51:23 PM

@elainekirk . Elaine there is regulation. This here seems highly unusual.
by Peter Melzer 7/9/2011 11:53:12 PM

@edano, remember I called the cubes at Fukushima impact friendly? When I saw the girders of the upper floor after the explosion, I wondered whether tepco ever worried about impact from the outside.
by Peter Melzer 7/9/2011 11:55:54 PM

@Peter Melzer it does it needs the company at least to look into it
by elainekirk 7/10/2011 12:01:01 AM

Cooper couldnt have shut down safetly in the event of a fire in this report issued in Marh after a Nov 2010 inspection pbadupws.nrc.gov
by elainekirk 7/10/2011 12:02:32 AM

Some images of Cooper to review regarding containment wp.me
by lillymunster 7/10/2011 12:04:39 AM

@Peter & @elaine - I'm just concerned whether or not the truck driver was aware of any of this or protected against it in any way... Troubling.
by ms in la 7/10/2011 12:06:53 AM

@ms in la , some package must have broken open. That those guys do not need to survey the truck? The stuff is usually really well packed.
by Peter Melzer 7/10/2011 12:11:12 AM

@lillymunster well found :) @ms in la yeah nobody is gonna sit in a radioactive truck all day volunarily
by elainekirk 7/10/2011 12:11:20 AM

@elainekirk Not to mention anyone who happens to be driving near him! If we are to believe the video readings... I'll bet the company has received calls already from the YouTube. And is busy sweeping up the evidence... er, I meant....rectifying the situation...
by ms in la 7/10/2011 12:13:02 AM

@elainekirk , I hope the company knows about it.

How far was that guy hauling that stuff? Long cross country drive could have added up.
by lillymunster 7/10/2011 12:15:36 AM

@All hi, sorry to draw attention away from the radioative truck...I had to disagree with something @Maji said to @Lilly about the sth hemisphere and the fuku radiation....being a so-hemi child I know all to well we did get smacked by fuku rads and still do.... no doubt, we will never see major amounts hit us but none the less detectable levels did interchange and "JUMP" across the ICV, generally speaking the ICV keeps us safe but it moves around and certain weather patterns and events causes a "jump" which leads to everyones favourite nuclear plant managing to deposit a little ray of fuku-shine in our part of the world! Thankfully though we don't have jet streams pushing the crap down constatntly on us like the inhabitants on the northern hemisphere! Just wanted to clear that up....@ All hi anyways, hope you have all been well!

@Peter Melzer @ms in la @lillymunster I think the vid needs verifying and I need sleep I will bid you all g'night
by elainekirk 7/10/2011 12:21:58 AM

@elainekirk Nite Elaine!
by lillymunster 7/10/2011 12:24:17 AM

just a final thought when did tepco do the measurements that showed a 30cm? drop and where does the incline start ? if it was measured in month 2 and we can visually see it over month 4 then....
by elainekirk 7/10/2011 12:36:25 AM

I really want to find that cooper stuff
by elainekirk 7/10/2011 12:36:48 AM

@elainekirk May 16
Vertical: - 50 centimeters (it sank 50 centimeters)
Horizontal: 220 to 250 centimeters to the east.

There are two plots at Ex-SKF that could possibly be used to pinpoint movement more

@lillymunster and that was blogged May 16th
by elainekirk 7/10/2011 12:49:57 AM

@elainekirk right and the data was obviously gathered before than and we know some things have shifted since then.
by lillymunster 7/10/2011 12:54:15 AM

@lillymunster it is a mess I dont see how they expect those sfp's to last another 3yrs
by elainekirk 7/10/2011 12:55:42 AM

@lillymunster, ms, I sent them an e-mail. Folks are strange! I checked the comments to the video. Plenty people concerned with the driver's fertility and our loser government failing us one more time. Only one other commenter asked whether anyone called the company. The people who received the leaking package must have been very upset!
