That's really two questions, "What are the uses of Nuclear fission reaction?" and "What are potential uses of nuclear fission?". See the "Related questions" below for answers to each question.
When some bacteria reproduces, it uses binary fission.

The fission of U-235 and Pu-239
There are two primary design styles of fission reactors to produce electricity. Pressurized, and Boiling water reactors.
All the operating reactors use fission, practically all with U-235, a few with Pu-239, and sometimes with a mixed fuel (MOX)
Fission of uranium and plutonium is mainly used to produce electricity, but also smaller reactors are used to produce radioisotopes for medical and industrial use
They are: 1. Tapeworm 2. Jellyfish 3. Bacteria 4. Amoeba Yeast doesn't use binary fission, it uses budding
Fission gives off heat, neutrons, and fission products. Each of these things has different uses. The heat is the primary product. It is typically used to boil water, the steam being used to power a turbine, which turns a generator to make electricity. Neutrons can be used to turn atoms of one element into atoms of another element. For example, tritium can be manufactured by exposing hydrogen in water to neutrons. The tritium, in turn, has uses ranging from nuclear fusion to tracing flow in ecological systems. Some of the products of fission have their own uses and are easiest obtained from materials that have been in reactor cores. An example is cesium-137, whihc is a fission product, and has uses in medicine and industry.
