@smoss Iaea reports site is probably getting hammered right now.

@lillymunster Maybe that's my cue to sleep on it and re-approach in the morning. :-)

What a week this has been, do we really need all these reactors all over our planet!? I mean Australia gets along just fine with out them.

US Corps concerns about keeping up with water on Missouri River www.stltoday.com
by lillymunster 6/21/2011 3:07:43 AM

@lillymunster , I found another instructive document on BWRs and design differences and history. This time by the IAEA: www.iaea.org . According to this document Oyster Creek is a BWR/2 design whereas Fukushima 1 unit 1 is a BWR/3 comparable to Dresden 2. So this blogger we talked about last night had it wrong.

More people in Fukushima fearing contamination
Concerns over radioactive contamination are growing among people living next to the new evacuation advisory zones near the crippled Fukushima Daiichi nuclear plant.

The people live just outside an area in Date and Minami Soma cities that the government last week designated for voluntary evacuation.

On Monday evening, Minami Soma city officials visited the homes of 5 families in Jisabara district, next to the zones.

The officials checked the radiation levels around the houses at the request of the concerned residents.

The highest level recorded was 2.45 microsieverts per hour at 1 meter above the ground in the houses' backyards. www3.nhk.or.jp

@Lilly Mother nature is having her way. Hopefully their emergency plans have taken that into consideration.
by LM 6/21/2011 3:15:34 AM

@LM Hey, that's 106,596 cubic meters. A few more of those, in sturdier stuff, and they'd have a place for all that water! ;)
by radioguy 6/21/2011 3:22:18 AM

@radioguy True..it's a shame it's polyester. I have my doubts about this plan, but I have my fingers crossed!
by LM 6/21/2011 3:25:48 AM

@LM The last I read tonight said they corps may have to run Gavins Point at 150k until August. They are talking about taking it to 160k and that was before the rain. They seem worried about Oahe still also. I thought this was going to be done by now.
by lillymunster 6/21/2011 3:26:21 AM

It's the Prying Eyes Containment, I fear.
by radioguy 6/21/2011 3:26:26 AM

@radioguy I suspect you're correct.
by LM 6/21/2011 3:28:37 AM

@LM We have to assume it will let the steam through, right? So the point is??
by radioguy 6/21/2011 3:30:12 AM

@radioguy , I was wondering about that, too. And where will the heat go? It is going to melt the plastic!
by Peter Melzer 6/21/2011 3:31:35 AM

@Lilly And if the rains continue unabated it's going to become an even bigger problem. I'll have to cross my toes and fingers!
by LM 6/21/2011 3:31:36 AM

@radioguy I'm really hoping that the cap piece is going to have some sort of filtration...otherwise you're exactly right...what's the point?
by LM 6/21/2011 3:33:01 AM

The other question is isotope build-up on the inside of the polyester. How are they going to be able to work inside it...even with potential filtration?
by LM 6/21/2011 3:35:55 AM

The idea was to be able to filter the air and lower the levels so workers could stay in longer, right? That was one of the rationales I read.
by radioguy 6/21/2011 3:39:21 AM

If they can do that, applause all around. It's experimental nuclear disaster management. Every day it's a new adventure.
by radioguy 6/21/2011 3:40:44 AM

@radioguy Unless they have something up their sleeve we don't know about the tent vs.the humidity and ventilation seem to be at odds with each other.
by lillymunster 6/21/2011 3:42:50 AM

@radioguy I think the only way levels wouldn't be outrageous on the inner walls would be if they could engineer something akin to an attic fan at the top that's equipped with filtration, but they'll run into the same issues as the contaminated water, as they have to change the filter too frequently.
by LM 6/21/2011 3:43:03 AM

@LM Exactly. Filtration doesn't eliminate sublimation on the walls.
by radioguy 6/21/2011 3:46:02 AM

It might lower the contact time.
by radioguy 6/21/2011 3:46:48 AM

I'm beginning to think it's just a matter of them looking busy for as long as they can for the next few years.....as scary as that sounds. I hope I'm wrong!
by LM 6/21/2011 3:47:53 AM

I read up on these last night on a Japan conservation blog. The small L-ion battery packs for your house. The can be charged off the grid for back up power or charged via solar or wind. www.bloomberg.com
by lillymunster 6/21/2011 3:49:14 AM

@Lilly Interesting article! I'm going to be fundraising for my sons' robotics teams and one of our initiatives involves selling these fabulous LED bulbs. This whole crisis gives the First Robotics fundraising program new meaning!
by LM 6/21/2011 4:06:50 AM

@LM Are they doing it as a school fundraiser? I saw something when I was researching LeD lights about school fundraiser packs some company was doing. Smart time to do that.
by lillymunster 6/21/2011 4:08:26 AM

@Lilly It's for their high school robotics teams, but First and Dean Kamen have offered these bulbs as a green fundraising tool for all First Robotics teams worldwide. It's incredibly awesome. My younger son's team went all the way to the final at the St. Louis World Championship this past April and Dean Kamen demonstrated the bulbs during the awards ceremony. They are virtually indestructible, non-toxic, and look and behave like a normal incandescent.

@lily FIRST® announces the introduction of the FIRST® Green
e-watt saver, an exclusive, state-of-the-art,
7-watt/450 lumen high-performance LED light bulb that features longer life and significantly lower energy consumption than conventional incandescent bulbs.

The problem is that CFL's are almost as efficient and much cheaper. I have an idea for a LED bulb design that might work on 120 AC, I'll build a prototype in the next few days and see if it works.
by Ralph Unger 6/21/2011 4:29:51 AM

CFLs are toxic, painful on the eyes, and loaded with mercury. I'd pay extra for safe and non-toxic...just my 2 cents.
by LM 6/21/2011 4:32:18 AM

If I can drop the rectifier, (AC to DC) I could save a lot on the cost. Good point LM, I just can't spend that much when I know LED's will be much cheaper in a few years.
by Ralph Unger 6/21/2011 4:33:31 AM

When I started working with white LED's they were $7 apiece. Per LED, not bulb.
by Ralph Unger 6/21/2011 4:34:27 AM

@Ralph No arguments..that's why this fundraiser works for the kids because they're considerably lower than cost. It's a great way to get a discount and support technology in the schools. I too hope the costs come down soon!
by LM 6/21/2011 4:35:36 AM

I use LED's a lot in theater lighting, cost is not as important there.
by Ralph Unger 6/21/2011 4:36:49 AM

@Ralph That makes sense. My husband and I have been stupidly holding on to the incandescents because we hate the CFLs. I Look forward to cheaper LEDS and this new generation is promising.

Well, it's time for bed. Night all!

False colorization adds remarkably improved fine-detail detection. This link points to a spot whereafter stream starts really rolling out of 4 (not my video) : www.youtube.com
by Ian 6/21/2011 4:45:14 AM

A lot of 'steam' there is ambient fog blowing in from the left, but with the false colors you can see the stream that is specifically from Unit 4 (or possibly 3) as a darker green.
by Ian 6/21/2011 4:48:13 AM

As this is a public document I guess I can mention my idea about LED's without DC power, I plan on using two series of LED's which will use 120 v with opposite polarity to give a steady 60 Hz light. 1 string will be lit on the + in the AC cycle and another will be lit during the - AC cycle. Wish me luck. :-)
