In this worksheet, we will practice describing the advantages and disadvantages of generating electricity from nuclear fission.
Which of the following correctly describes how energy is released from uranium in nuclear reactors?
- AUranium nuclei radiate microwave radiation, which is absorbed by the material around the uranium in the core of the reactor, heating it up.
- BUranium nuclei radiate gamma rays, which are absorbed by the material around the uranium in the core of the reactor, heating it up.
- CUranium nuclei emit electrons, which are used directly to generate electricity.
- DThe nuclei of uranium atoms split, releasing energy stored within the nucleus and causing the uranium and the material around it in the core of the reactor to heat up.
Which of the following statements correctly describe the disadvantages of nuclear fission reactors?
- Nuclear fission reactors are expensive to build.
- The planning, construction, and testing process for nuclear fission reactors take a long time.
- Nuclear reactors are slow to start up if they are switched off and slow to switch off once running. This means that they cannot respond to changes in electricity demand.
- Nuclear fission reactors are expensive to maintain.
- Nuclear fission reactors release large quantities of carbon dioxide and methane into the atmosphere once built.
- Nuclear fission reactors produce very little electricity.
- Nuclear fission reactors produce highly radioactive waste that has to be stored securely for hundreds of years.
- The process of refining uranium to be used in fission reactors creates a lot of pollution.
