Ιστορικό πυρηνικών δοκιμών

Ο Isao Hashimoto έφτιαξε ένα ωραίο βίντεο, με θλιβερή υπόκρουση, που δείχνει τις εκρήξεις από πυρηνικές δοκιμές που έχουν γίνει από το 1945 μέχρι το 1998.
Δείχνει τόπο έκρηξης, μέγεθος έκρηξης και υπεύθυνη χώρα, καθώς ένας μετρητής δείχνει έτος και μήνα.
Δεν δείχνει πυρηνικά ατυχήματα, οπότε μπορείτε να σκεφθήτε ότι η τελική εικόνα είναι σαφώς χειρότερη. (Είναι πολλές οι εκρήξεις! Άρη, σου ερχόμαστε!)



Το βρήκα σε ένα άρθρο της Κατερίνας Κοντίνη στο TVXS, που το βρήκε σε μια ανάρτηση του Πιτσιρίκου.



Αν σας ενδιαφέρει η εξάπλωση της ραδιενέργειας μετά την έκρηξη στο Chernobyl, μπορείτε να δείτε ένα πολύ ενημερωτικό βίντεο εδώ.



Αρχίζουν να δημιουργούνται κινήσεις εναντίον των πυρηνικών, πχ. : εδώ.

Δεν παθιάζομαι με τις ομαδικές διαμαρτυρίες, αλλά τα πυρηνικά είναι επικίνδυνα και οι άνθρωποι ολιγόζωοι και φιλοπόλεμοι. Αν σας ρωτήσουν, να είσαστε εναντίον των πυρηνικών.

The problem here is that with all this anti-nuclear-plant hysteria, we have not been gaining much experience in engineering better plants. People routinely die in the thousands in coal mines, lots of wars are being fought over oil, and we won't even mention the adverse effects to the environment of burning all those fossil fuels, from greenhouse gases to heavy-metal contamination of aquifers, to actually releasing radioactive material into the atmosphere (look up the numbers on how much radioactivity is being released by a typical coal plant).
Solar power is still not economical given current oil prices, we are a long way before we can process silicon cheaply enough to build enough solar arrays to cover even a small fractin of our power needs, and fusion is still not much nearer to providing a usable power source than it was fifty years ago.
In short, fission plants (modern designs, not the antiquated designs of things like the chernobyl plant) are the environmentally friendliest power source we can hope to have for a long time.

Engineering is about managing and mitigating risks. When politics interferes, only bad things can happen.

Linear progress is an illusion. Thinking in algebraic terms of minimizing (cost of energy+environment impact) is wrong. A single human life is invaluable. States that build nuclear plants are like smokers who ignore non-smokers.

Fossil-fuel plants have killed many more people than nuclear plants per MWh generated. Check your data. As for the value of human life, tell that to all the people who are getting killed over the middle-east oil. What do you suggest we burn instead?

Dear friend (although I don't know you), I think you totaly missed my point --or I did not make it clear enough. Wars could (or will, for some analysts) be fought in the not so distant future for water as well --there will be always an excuse for the gun industries to sell their products. Answering your question: If we were intelligent, we would just slow down production or even "progress" by adopting only harmless forms of energy. Still you did not make a comment to my other remark (the smoker example). Greece is encircled by countries using fission plants. Do they have the right to put a neigbor country in danger?

Dear friends, ji & gk, your intelligence and knowledge is commendable. But if you are willing to accept a third opinion, please listen to me.
Nuclear fission plants are not manageable, not in this unsteady planet.
Slowing the pace of "growth" might actually be real progress.
Having a picnic with friends on the grass of a park is enough to make you happy. Having an expensive dinner on a revolving restaurant on the 70th floor of a skyscraper, is a praise to technology, but it is too much!
We engineers can achieve it, but this is not a persuasive reason to do it! I think we should aim for the long sustainable happy life of humanity, not the steepest economic growth.
