Ensuring the supply of energy worldwide is a key challenge for utility companies nowadays. In many developing economies, for instance, water-dependent and power-hungry economic growth is placing an immense strain on the infrastructure of these nascent markets.

Likewise, nuclear power is once again about to assume an important place in the energy policies of many countries.
