The speaking module

II. Speaking exercises:

Exercise 1. Learn the definitions: Nuclear power plant; nuclear reactor; reactor core; safety valve; generator.

Nuclear power plantis a thermal power station in which the heat source is a nuclear reactor.  

Nuclear reactor -a device used to generate power, in which nuclear fission takes place as a controlled chain reaction, producing heat energy that is generally used to drive turbines and provide electric power. Nuclear reactors are used as a source of power in large power grids and in submarines.  

Reactor core -nuclear reactor core is the portion of a nuclear reactor containing the nuclear fuel components where the nuclear reactions take place.  

Safety valve -a valve in a pressure container, as in a steam boiler, that automatically opens when pressure reaches a dangerous level.  

Generator- an apparatus in which vapor or gas is formed from a liquid or solid by means of heat or chemical process, as a steam boiler, gas retort, or vessel for generating carbonic acid gas, etc. An electromechanical device that converts mechanical energy to electrical energy (usually direct current).

Exercise 2. Ask questions to the given answers:

1) Question: ___________________________________________?

Answer: In the event of an emergency, two independent safety valves can be used to prevent pipes from bursting or the reactor from exploding.

Question: __________________________________________?

Answer: The water level in the steam generator and nuclear reactor is controlled using the feed water system.

Question: ___________________________________________?

Answer: The purpose of the steam turbine is to convert the heat contained in steam into mechanical energy.
