HideShow resource information
what is a fissionable isotope
an isotope that can undergo the process of fission
1 of 12
which 2 fissionable isotopes are used in nuclear reactors
uranium-235 and plutonium-239
2 of 12
when does a chain reaction occur
when each fission event causes further fission events
3 of 12
what is nuclear fusion
the process of forcing to nuclei close enough together so they form a single larger nuclei
4 of 12
how can nuclei be made to come close enough to fuse
nuclear fusion can be brought about by making 2 light nuclei collide at very high speeds
