Nuclear Physics 10: Electrical Energy from Fission

A dated yet informative video looking at the Fission Process (the video appears to cut short but it seems concise enough).

have we got a part 2??? i enjoyed that thanks ;~}

[stevebd1]

Unfortunately that's all there is on that one.

I NEED MORE...

Yes! Plain English! Despite weird stuff, I like youtube. I am of average intelligence -maybe- and found this palatable to my curiosity. Thank you stevebd1! plus thanks for the link.

part two is missing !!

Great video !! thank you

I like the fact that it is NOT claimed that it will EXPLODE, and enough information is given here for people to realize that a "critical mass" of U 235 will NOT explode, since only slow neutrons can cause a fission, and only fast neutrons are released as products of fission.

@rockerlkj Can't tell if I'm trolling? You must be really stupid.

@Kostly Can't tell if trolling, or just really stupid...

HAHAHAH....when does this video mention it is pure insanity to use fission to generate STEAM to turn turbines? I mean, really? Are we so blinded by science to understand that this is an insane way to generate energy (heat)? Fucking crazy. Meanwhile, the monied interests reject solar, wind, tidal and geo-thermal means to generate the SAME heat. Humanity is in serious trouble. The only way out is to remove the monied interests.The pirates of consciousness and humanity.Find them and killem.

@eacao Uranium-239 is incredibly unstable, lasting about 20 minutes before it decays into neptunium-239. That lasts for about a couple days (literally), before decaying into the long-lived, fissile plutonium-239.

The main problem is what to do with the uranium-236. When the U-235 atom is hit with a neutron, there is some 18% chance it remains stable and doesn't fission, and just absorbs the new neutron. U-236 is basically very long-lived nuclear waste, lasting millions of years. What to do?

@jamybrainy Like in the movie, when a uranium-238 absorbs a neutrons, it becomes uranium-239. Uranium-239 has a half-life nigh higher than 20 minutes, and decays into neptunium-239 via beta decay. Neptunium-239 also quickly decays via beta decay into plutonium-239.

@stevebd1 You mean, that's all of it? Nothing more was produced? That's kind of weird, there wasn't the typical ending music, and the ending seemed very abrupt. Are you sure?
