Fission Energy

4. A substance that chokes a fission reaction in a reactor core
5. The part of a reactor that is rotated by steam, generating rotational mechanical energy
8. A charge neutral particle which is crucial in the fission process
9. A substance used to moderate the temperature of a system, such as water
10. An acronym that describes a material with 3%-5% U-235, also called "reactor grade" uranium
11. One of the most common elements used in nuclear fission
12. The highest-frequency form of electromagnetic energy
14. An adjective to describe whether or not a material is reactive enough to undergo fission
15. The nuclear alternative to fission, which currently is not fully harnessed
16. Substances produced from fission reactions that are hard to cleanly dispose of
17. A tube made out of a neutron-absorbent substance like cadmium, indium, or silver to moderate the rate of fission
19. The fissile material at the heart of a reactor

1. Fission is roughly 8,000 times more effective than this energy source
2. The splitting of heavy atoms via interaction with neutrons
3. A noble gas with a very prominent neutron poison isotope
6. Energy that holds together the atom that is being split apart, must be overcome to instigate fission
7. The part of the atom accounting for nearly all of its mass, made of protons and neutrons
9. one of the worst nuclear disasters in world history, located in Ukraine
13. An alternative type of reactor which can avoid xenon and krypton build ups, as well as the threat of hydrogen explosions
18. A cleaner, more abundant element that can be used to generate nuclear fission without uranium
