Welcome to c/science_memes @ Mander.xyz!
A place for majestic STEMLORD peacocking, as well as memes about the realities of working in a lab.
Rules
- Don't throw mud. Behave like an intellectual and remember the human.
- Keep it rooted (on topic).
- No spam.
- Infographics welcome, get schooled.
This is a science community. We use the Dawkins definition of meme.

Miniature breeder reactor
You would drop in the uranium fuel source and it would be used to create more fuel.
Short version is most early nuclear science focused on breeder type reactors but they were abandoned when it was found that more conventional designs are a lot more feasible for producing weapons grade material.
The weapons grade stuff is U-235, right? Do conventional nuclear reactors enrich U-238 to U-235?
Uranium 235 or plutonium 239, may be completed with Hydrogen for more energy release: deuterium and tritium.
AFIK natural uranium is mainly centrifugated for the heavier 238 and lighter 235 to separate. Enriched uranium is just having a higher percentage of 235.
Plutonium 238 is man made in reactors
Uh, that understates things a little bit. Hydrogen bombs (which utilize fission for triggering the fusion reaction) are generally a few orders of magnitude more powerful than fission bombs. The opposite is more accurate: fusion bombs that use spent Uranium as a tamper roughly double their yield.
