Exercise 1. Read and memorize using a dictionary:

IAEA (International Atomic Energy Agency); the EBR-I (Experimental Breeder Reactor I); load stations; a light water reactor; a multi-stage steam turbine; thereby; protective shield; a dome of concrete; casualties; align; debris; the outlet steam; an activity meter; in contrast; low-pole AC synchronous generators; safety valves; bursting; exploding; a heat exchanger; feedwater pump; Emergency power supply; redundancy; battery buffers; battery backup; uninterrupted; shut down;  

Exercise 2. Answer the questions:

1) What is a nuclear power plant?

2) How is the heat produced?

3) What doesa cooling system remove?

4) How is the water level in the steam generator and nuclear reactor controlled?

Exercise 3. Match the left part with the right:

1. Electricity was generated by a nuclear reactor for the first time	a).to initiate and control a sustained nuclear chain reaction
2. A nuclear reactor is a device	b) ever on December 20, 1951.
3. In the case of a pressurized water reactor,	c) are connected to the intermediate cooling circuit.
4. The chambers on a heat exchanger	d) the steam turbine is separated from the nuclear system.

Exercise 4. Open brackets choosing the right words:

Since nuclear (fission/splitting) creates radioactivity, the reactor (core/centre) is surrounded by a protective shield. This containment (absorbs/ejects) radiation and prevents radioactive material from being released into the environment. In addition, many reactors are (equipped /furnished), with a dome of concrete to protect the reactor against both internal casualties and external impacts. In nuclear power plants, (different/various) types of reactors, nuclear fuels, and cooling circuits and moderators are used.
