Understanding nuclear: reactions, radioactivity, waste

[Obamot]

My little finger tells me that there are some points that duplicate others already in this thread:
https://www.econologie.com/forums/nucleaire- ... 10628.html
And even in this one:
https://www.econologie.com/forums/accident-n ... 10579.html

And it's a shame ... because by "broadcasting" the info left and right, important points will be lost, nan?

[Christophe]

Obamot is right even if we can not put everything on track, nevertheless this:

At the moment, on France Info: radioactivity has just jumped to Fukushima. It is question of radiocativity multiplied by 10 millions !!! ??????

Surely the MOX reactor 3 who smoked gray ????

... is completely Off Subject, this is where we talk about evolution info at fukushima: https://www.econologie.com/forums/accident-n ... 10579.html (you are probably talking about the "puddle" see last messages from https://www.econologie.com/forums/post198527.html#198527 )

So to summarize the classification of the nuclear subjects of the moment (There is already one here: https://www.econologie.com/forums/nucleaire- ... 10628.html ):

a) this subject = https://www.econologie.com/forums/comprendre ... 10606.html = nuclear physics = understanding of nuclear

b) https://www.econologie.com/forums/nucleaire- ... 10628.html = consequences (technical, pollitic, economic ...) to be drawn from the disaster (= change "the" system?)

c) https://www.econologie.com/forums/accident-n ... 10579.html = event tracking

This morning I added this one: https://www.econologie.com/forums/accident-n ... 10640.html

My reaction is as follows: of course, we cannot get out of nuclear power in just two teaspoonfuls. But the Fukushima accident gives us the opportunity to review everything! And thank you to Éconologie.com for opening its forum for in-depth reflections and without price (note the "x") ;-)))))

So to "understand" let's start with some aspects "business side" of the electricity market
It is a very protected market with very distant fluctuations (the events of Fukujima will have an impact on the electrical bill only in a year ... if there is one).
Paradoxically, the price of electricity is based on the price of fossil fuels! So, on the one hand, we have extremely stable costs and on the other, a rising fluctuation which is all benefit. This is therefore very attractive as a "market"!
Thus in the tiny Switzerland - from power generation to power distribution to wall outlets - there is no less 900 different operators !!! For 24 cantons ... To say that the fight is very unequal between this lobby and the public administrations ...

On the side of the figures it is more pleasant, as long as there is no "catastrophe". Only 40% of the cost of the electricity bill is dedicated to the "production" of energy ...

If I take out my slide rule (joke inside ...) I see with this figure that:
1) the yield of 18% "of the best of photovoltaics" would be amortized in just 2 years according to the producer of these panels.
2) if we save on distribution - which should de facto be the case with localized energy production - "the best of photovoltaics" becomes viable, even under our latitudes (there are already houses + which produce up to 35kW, which allows them to inject current into the network since they produce more than they consume).
3) "big jobs" would be for deep heat storage in summer for reuse in the cold season, but it will always cost less than 500 / 1000 billion!
4) the independence of the energy supply would be maintained thanks to the huge savings made on fossil fuels, no offense to our Minister of Economy "pro lobby nuke" which sees all kinds of obstacles to the exit of this filiation ...
5) thanks to the Arab Spring, let's hope that the emergence of Désertec will be facilitated ...
6) the sites of Désertec will benefit perfectly from the upward fluctuation of the electrical energy, so there is nothing contradictory on the economic level.
7) the electricity market is an economic sector where there are only "captives" (consumers), so there is no possibility of a fiasco to venture into the many possibilities offered by Renewable energies ... In the end, we will arrive at an average kW / h price, which will always be lower than the actual cost of the nuke! QED.
8} also let consumers choose the type of supply they want! But before, let's fix the REAL cost of the energy correctly according to its origin! The choice of consumers will be made quickly ... And we will come out quickly ...

In short, there are only advantages to getting out of the nuke amha. To the legislator to do his job ... Consumers to demand to be able to fix their choice ... And if need be, the people to press!

Video of the BBC (according to the title but to check) 30 minutes to see on the biological effects of radiation (following Chernobyl in particular):

http://www.youtube.com/watch?v=63eysDq7fvM
http://www.youtube.com/watch?v=WBoYAybUE2I

At the beginning of the 1e part, they talk about 20 / 30 devices which voluntarily increased the radiation (in small doses obviously) to improve the health ...

A recent study of a population that naturally receives 200 mSV per year (!?!) At the end of the 2ieme part indicates the same trend: there could be a benefit to radiation for anti cancer genes ...

[Cuicui]

It should be made clear that this is the nuclear fission of uranium. Other nuclear reactions (hydrogen-boron fusion, for example) do not have these disadvantages.
Putting all the nuclear reactions in the same bag is confusing.

[Addrelyn]

Addrelyn was right: we got 7% PN after shutdown:

Still happy...

For teachers, I think they are, like the majority of French, nuclear friendly. A story of propaganda ... We are not in the USSR and I do not think that national education has propaganda messages to convey ...

To scare you a little more, there is plutonium in all nuclear reactors, MOX or not. (It is created from the U238 + n during the reaction) It represents 1% by mass of used fuels.
the U232 is also disgusting radiopro level.

Radiotherapy is already known for a long time, right?

It's not exactly that, the radiation at certain doses, would block some effects by killing them in the bud. To tell the truth, still many doctors are reluctant even to make a single radio (when they make their assessment of the equation: Risk / beneficial effects VS negative effects)

Typical bikers who "manage the risk" saying it's not dangerous, nan?

In reality, there are other ways to manage it upstream, in terms of prevention, before reaching the healing effect, like horse treatment in firefighting medicine that extinguishes the fire!

[Christophe]

Yes except that, from what I know (ie not much), the radiotherapy is very targeted towards the sick cells not? Radiation therapy does not affect the entire body.

And 200 mSV per year, unless error of the report is:

a) 100 times the normal dose
b) The doses taken by the most exposed "liquidators" of Fukushima

[Addrelyn]

Yes except that, from what I know (ie not much), the radiotherapy is very targeted towards the sick cells not? Radiation therapy does not affect the entire body.

Yes, 80 Gy on sick cells, and 1 Gy about unfortunately on the rest ...
It's still worth the risk of cancer in 10 years rather than die in 2 months ...

For the media figures, when I do TP with radioactive sources, I hold 12 in my hands at 300kBq each which must be 1 000 000 natural radioactivity times. Yet I risk nothing, because these sources emit alpha that do not cross the dead skin layer of my hand.
I can say anything to the numbers by always telling the truth. Appropriate these numbers, try to understand. Similarly for units, Sv, Bq, Gy.
After, you can defend or go down the nuclear, as you want, but you will not be ridiculous when you talk to someone who knows ...

[dedeleco]

1 Gy about unfortunately on the rest ...

and the rest is only a few cells around and in the patients, otherwise the patient dies more quickly.
Around 0,1gray, the max possible on the whole body, it tans, loses its hair, and is very disturbed with many reactions called secondary !!

So I remember my former manager, appeared one day suddenly tanned in the winter and 15 days later was dead, by radiotherapy treatment probably not well calculated, but I never knew In addition, the Department of Economic and Social Affairs of the ?
Like many others instead of dying in 10ans have died much faster in less than two months not resisting the violence of treatment !!

The anti-cancer treatments are very violent pound hammer type to crush a fly that escapes constantly hoping to end up crushing it without crashing yourself !!

What is worth it is the prevention and to live without chemical pollution everywhere, and radioactive carcinogenic by feeding without junk food neither rotten or radioactive air !!

Finally, in my youth, millions of fluorescent radioactive watches were sold with addrelyn TP source, who should collect them these old watches, given his love of radioactivity.
But do not swallow their dust or have too much on the wrist!
