Fuel assembly, active core volume, fission product decay, neutron absorption capacity; heat-insulating material, energy-releasing reaction, steam-generating equipment, ion-attracted electrons, liquid metal-cooled fast breeder reactor; radiation shielding; control-rod-and-shield-material specimens, loss-of-coolant accident.

B. Read and translate the following sentences

I

1. As a gas is cooled, it loses heat as well as energy.

2. The concept of the breeder reactor is almost as old, as the idea of nuclear chain reaction.

3. Because of their energy, the molecules of a liquid are always in rapid motion.

4. Both nuclear power and solar energy will be used in future.

5. The pipe didn’t rupture and the accident didn’t take place either.

6. This particle has a mass the same as that one.

7. All countries should use nuclear power for peaceful purposes only.

8. The only fissionable material found in nature is U²³⁵.

II

1. Since this gas does not become radioactive there is no need for another heat-exchanger.

2. The main feature of a nuclear reactor is that the products of reactor operation are radioactive.

3. The fuel of the Candu system is very similar to that of a LWR in that fuel pins are arranged into bundles.

4. Both reactions should take place at a time.

5. The amount of fuel is reduced by the time the bundle is re-moved.

6. Nearly 1% of the neutrons are delayed for intervals ranging from a fraction of a second to more than a minute.

7. Changing the resistance in the circuit we can control the flow of current in the circuit.

8. The Curies worked hard before they discovered the phenomenon of radioactivity.

III

1. This substance conducts so little electric current that it is hardly measurable.

2. After such reprocessing the radioactive products are readily extracted.

3. The number of cycles per second is the frequency of the alternating current.

4. We believe breeders will result in a transition to massive use of nuclear energy.

5. Light-water reactors are in turn classified as either pressurized-water reactors or boiling-water reactors.

6. Coal should be turned into synthetic gas and oil.

7. The operators believed there was too much water in the primary system but there was too little, in fact.

8. The world’s uranium and thorium resources will last very long.
