Charles Till and Yoon Chang describe the evolution of the Liquid Metal Reactor, the development of the Integral Fast Reactor. This is a key step to providing plentiful energy for the world for a very long time.
In 2000 the concept of Generation Ⅳ(GⅣ) Advanced Nuclear Systems was proposed by the United States and approved by numerous nuclear power countries in 2001, which includes six types of reactor systems: Sodium Cooled Fast Reactor (SFR), Gas Cooled Fast Reactor (GFR), Super-Critical Water Reactor (SCWR), Lead Cooled Fast Reactor (LFR), Very High Temperature Reactor (VHTR) and Molten Salt Reactor (MSR). Right now the fast reactor development in China is under the experimental reactor stage, then it will be step by step going to prototype and commercial sized demonstration fast reactor stages.
Less than 200 years earlier, people were walking 2,000 miles on foot, with ox drawn wagons across America to settle Oregon and California. People had been walking like that for the previous 100,000 years and more. With the development of nuclear power from fast breeder reactors, the world now has a limitless supply of clean, affordable, reliable energy to improve living standards and protect the environment.
Professor Emeritus of Physics at the University of Pittsburgh. Professor Cohen was a staunch opponent of the so-called Linear no-threshold model (LNT) which postulates there exists no safe threshold for radiation exposure: We conclude that all the world's energy requirements for the remaining existence of life on Earth could be provided by breeder reactors without the cost of electricity rising by as much as 1% due to fuel costs. This is consistent with the definition of a "renewable" energy source.
