Reformatted from: Van Wyk, Rias J: Technology - A Unifying Code, 2004, SMG, Cape Town, p.34. Based on: Ropohl, Gunter: Eine Systemtheorie der Technik, 1979, Carl Hanser Verlag, Munich and Vienna, p.178.
This Newsbrief deals with the generation of electricity using nuclear power. More particularly it focuses on requirements for ensuring the safety of nuclear reactors. In terms of the Atlas of Technological Megatrends it is concerned with the functionality of energy processing.
Recent months have seen increasing international interest in the safety of nuclear generators. This has been precipitated by damage to the Fukushima facility in Japan, and environmental threats to facilities in the USA. Three countries, Japan, Switzerland and Germany have indicated that they are considering the discontinuation of nuclear facilities.
While there is general agreement on the increased safety standards adhered to by modern generator design, there is an increasing awareness of the need for a more comprehensive approach.
Four factors have to be taken into account:
  • Inherent design of the reactor
  • The uninterrupted supply of electricity from a source independent of the nuclear power station
  • The uninterrupted supply of water for cooling
  • The safe storage of spent fuel
While there is increasing confidence in dealing with the first factor, the other three are causing concern. More and more operators and regulators are realizing that it is unlikely to attain complete satisfaction. Even though high levels of redundancy can minimize danger, it is never possible to achieve 100% perfection. The implications of failure, even if highly improbable, are so large as to seriously question nuclear viability.
