Nuclear Power worksheet with fill-in-the-blank and classification exercises.

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 (A) or disadvantages (D).

#### Statements:
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. It does not contribute to global warming, ozone depletion, and does not cause acid rain.
5. It does not produce carbon dioxide.
6. High costs of decommissioning old stations.
7. Humans exposed to higher than average levels of radiation develop cancers and leukemia.
8. It is still not clear how safe nuclear power is.
9. Many safeguards make accident risk minimal.
10. Non-renewable, limited supply.
11. Power plants employ lots of people.

#### Classification:
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): This limits the versatility of nuclear power.

3. Concern over disastrous effects if there is an accident.
- Disadvantage (D): This points to potential risks associated with nuclear accidents.

4. It does not contribute to global warming, ozone depletion, and does not cause acid rain.
- Advantage (A): This highlights environmental benefits of nuclear power.

5. It does not produce carbon dioxide.
- Advantage (A): This is another environmental benefit, as it reduces greenhouse gas emissions.

6. High costs of decommissioning old stations.
- Disadvantage (D): This indicates financial challenges related to nuclear power.

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

8. It is still not clear how safe nuclear power is.
- Disadvantage (D): This reflects uncertainty about the safety of nuclear power.

9. Many safeguards make accident risk minimal.
- Advantage (A): This emphasizes safety measures that reduce the risk of accidents.

10. Non-renewable, limited supply.
- Disadvantage (D): This points to the finite nature of nuclear fuel resources.

11. Power plants employ lots of people.
- Advantage (A): This highlights the economic benefit of job creation.
