Worksheet: Nuclear Power

In this worksheet, we will practice describing the advantages and disadvantages of generating electricity from nuclear fission.

Q1:

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.
  • CThe 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.
  • DUranium nuclei emit electrons, which are used directly to generate electricity.

Q2:

Which of the following statements correctly describe the disadvantages of nuclear fission reactors?

  1. Nuclear fission reactors are expensive to build.
  2. The planning, construction, and testing process for nuclear fission reactors take a long time.
  3. 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.
  4. Nuclear fission reactors are expensive to maintain.
  5. Nuclear fission reactors release large quantities of carbon dioxide and methane into the atmosphere once built.
  6. Nuclear fission reactors produce very little electricity.
  7. Nuclear fission reactors produce highly radioactive waste that has to be stored securely for hundreds of years.
  8. The process of refining uranium to be used in fission reactors creates a lot of pollution.

Q3:

Which of the following statements correctly describe the advantages of nuclear fission reactors?

  1. Nuclear fission reactors are cheap to build.
  2. Nuclear fission reactors are quick to build.
  3. Nuclear fission reactors produce extremely large quantities of electricity.
  4. Nuclear fission reactors are quick to start up to meet increased demand.
  5. Nuclear fission reactors are cheap to maintain.
  6. Nuclear fission reactors release no carbon dioxide into the atmosphere once built.

Q5:

Tuoketuo Power Station in China is the largest coal-fired power station in the world, with a power output of 6,720 MW. Kashiwazaki-Kariwa Nuclear Power Plant in Japan is the largest nuclear power station in the world, with a power output of 7,970 MW. What is the ratio of the power output of Kashiwazaki-Kariwa Power Plant to Tuoketuo Power Station? Give your answer to 3 significant figures.

Q6:

In the UK in 2017, the average electricity consumption per household was 3,760 kWh for the whole year. Torness nuclear power station in Scotland is one of the largest nuclear power stations in the UK and produces 11.9 TWh of electrical energy per year. How many households did Torness power station provide electricity for in 2017? Give your answer to 3 significant figures.

Q7:

In a small town, the average electricity consumption per house is 35 MJ per day. There are 1,200 houses in the town. A nearby nuclear power station provides electricity to the town via the national electricity network. The power station has an average power output of 2,800 MW. What percent of the power station’s output each day is consumed by the town? Give your answer to 2 significant figures.

  • A 1 5 %
  • B 0 . 0 6 7 %
  • C 6 . 7 %
  • D 0 . 0 1 7 %
  • E 0 . 1 5 %

Q8:

A nuclear power station has an installed capacity of 3,400 MW. If the power station runs at its installed capacity for 1 full day, how much energy does it produce? Give your answer in joules to 2 significant figures.

  • A 8 . 2 × 1 0 J
  • B 2 . 9 × 1 0 J
  • C 2 . 9 × 1 0 J
  • D 1 . 2 × 1 0 J
  • E 5 . 9 × 1 0 J

Q9:

Kori Nuclear Power Plant is a nuclear fission power plant located in South Korea. It is one of the largest nuclear power plants in the world. Its installed capacity is 6,040 MW. If the power plant was able to run at its installed capacity year-round, how much energy would it produce in 1 year? Give your answer in terawatt-hours to 2 significant figures. Use a value of 365 for the number of days in a year.
