Nuclear Power worksheet featuring fill-in-the-blank questions and a classification task on the pros and cons of nuclear energy.

Task 1: Fill in the gaps with words provided

The task requires filling in the blanks using the words provided in the word bank. Let's solve it step by step:

#### Word Bank:
- workers
- uranium
- turbines
- steam
- split
- reactor
- radiation
- nucleus
- generators
- gas
- fission
- energy
- electricity
- concrete
- boiler
- atom

#### Passage:
Nuclear power uses nuclear uranium to release energy.

At the center of each reactor, there is a nucleus. As an atom of uranium is split in a nuclear reactor, a great deal of heat energy is released. Heat from this reaction is harnessed for making steam.

A boiler takes the heat from the reactor to the boiler, where water is turned into steam. The steam is used to drive the turbines, which work the generators and make electricity.

A concrete shield around the reactor is made of concrete and is up to 4 meters thick to protect workers from dangerous radiation.

Task 2: Classify statements into advantages (A) or disadvantages (D)

The task requires classifying the given statements about nuclear power into advantages or disadvantages. Let's analyze each statement:

1. Although underground storage of nuclear waste possible, no completely safe way has yet been found to dispose of this waste.
- Disadvantage (D): This highlights a significant issue with nuclear waste disposal.

2. It cannot be used for heating or transport.
- Disadvantage (D): Nuclear power has limited applications compared to other energy sources.

3. Concern over disastrous effects if there is an accident.
- Disadvantage (D): Accidents at nuclear power plants can have severe consequences.

4. It does not contribute to global warming, ozone depletion, and does not cause acid rain.
- Advantage (A): Nuclear power does not emit greenhouse gases or pollutants that cause environmental damage.

5. It does not produce carbon dioxide.
- Advantage (A): Carbon dioxide is a major contributor to climate change, so this is a positive aspect.

6. High costs of decommissioning old stations.
- Disadvantage (D): Decommissioning nuclear plants is expensive and time-consuming.

7. Humans exposed to higher than average levels of radiation develop cancers and leukemia.
- Disadvantage (D): Radiation exposure poses health risks.

8. It is still not clear how safe nuclear power is.
- Disadvantage (D): Uncertainty about safety is a concern.

9. Many safeguards make accident risk minimal.
- Advantage (A): Safeguards reduce the likelihood of accidents.

10. Non-renewable, limited supply.
- Disadvantage (D): Uranium is a finite resource, making nuclear power non-renewable.

11. Power plants employ lots of people.
- Advantage (A): Nuclear power provides employment opportunities.

#### Classified Statements:
- Advantages (A):
1. It does not contribute to global warming, ozone depletion, and does not cause acid rain.
2. It does not produce carbon dioxide.
3. Many safeguards make accident risk minimal.
4. Power plants employ lots of people.

- Disadvantages (D):
1. Although underground storage of nuclear waste possible, no completely safe way has yet been found to dispose of this waste.
2. It cannot be used for heating or transport.
3. Concern over disastrous effects if there is an accident.
4. High costs of decommissioning old stations.
5. Humans exposed to higher than average levels of radiation develop cancers and leukemia.
6. It is still not clear how safe nuclear power is.
7. Non-renewable, limited supply.
