On the one hand, it allows nuclear power by way of controlled fission.

Plutonium is a by-product of the controlled fission reaction in a nuclear reactor.

Using controlled fission to power machines and synthesize isotopes.

A rapid but controlled fission reaction more like a nuclear power plant, generating heat rather than an explosion," Marshall responded. "

Then he pulled the lever actuating the cadmium rods which controlled fission in the Swiftonium pile.

The core of the fuel cycle – controlled fission of uranium atoms inside the nuclear reactor produces energy.

In a nuclear reactor the uranium fuel is assembled in such a way that a controlled fission chain reaction can be achieved.

Discuss the role of the moderator and control rods in the production of controlled fission in a fission reactor.

The second concludes that the controlled fission of uranium-235 could be a source of heat energy for powering machines and a source of radio-isotopes.

The second MAUD Report concluded that the controlled fission of uranium could be used to generate heat energy for use in machines, and provide large quantities of radioisotopes which could be used as substitutes for radium.
