1. Reading Exercises:

Exercise 1. Read and translate using a dictionary:

conventional heat engines , medium, can be dissipated, concern,

accident, storage of hazardous radioactive waste, extensively,

containment, advantage.

Exercise 2. Answer the questions:

.

1) What has made possible the large-scale production of atomic energy?

2) Where is the heat transferred to another medium?

3) What has raised concern over the safety of reactors?

4) What reactor would produce less hazardous radioactive waste?

Exercise 3. Match the left part with the right:

The heat energy in a reactor	differs considerably from that Of fission reactors
Another concern over fission reactors	heats a liquid or gas coolant
The design of nuclear fusion reactor	is the storage of hazardous radioactive waste

Exercise 4.

Open brackets choosing the right words:

(Fusion/ fission) reactors, for instance, would produce ( less/ more) hazardous radioactive waste. Because their fuel, (deuterium/ uranium) (an isotope of hydrogen readily separated from water), is far less (expensive/ cheap) to obtain than enriched (uranium/deuterium),( fusion / fission) reactors also would be far more economical to operate.

II. Speaking Exercises:

Exercise 1. Describe nuclear production of heat and fusion reactors using the suggested words and expressions:

Production of heat:

fissionable materials, the excess of nuclear fuel, reactor core,

radioactive, the heat is transferred, have raised concern, the storage

of hazardous radioactive waste.

Fusion reactors:

an alternative to, experimental stage, the containment of the plasma fuel, to initiate the reaction, to have many advantages, hazardous radioactive wastes, economical to operate.

Exercise 2. Ask questions to the given answers:

1) Question: _________________________________________

The excess nuclear fuel produced can be extracted and used in other reactors or in nuclear weapons.

2) Question:____________________________________________________

Submarines and surface ships propelled by nuclear reactors and nuclear-powered electric generating stations are in operation.

3) Question:_________________________________________________

Fusion reactors are being studied as an alternative to fission reactors.

III. Writing exercises:

Exercise 1. Complete the sentences with the suggested words:

extracted, released, excess, circulates, core, weapons, produced

The_______ nuclear fuel_______ can be ________ and used in other reactors or in nuclear _________. The heat energy ______ by fission in a reactor heats a liquid or gas coolant that ______ in and out of the reactor ______, usually becoming radioactive.

Exercise 2. Compose a story on the following topics (up to 100 words):

“Production of heat”

“Fusion Reactors”
