Earthquakes accompanied by tsunamis destroy Japan to bring thousands of victims. However, the disaster did not seem enough. Japan is now facing new problems, damage to a nuclear power plant whose condition was in danger.
This terrible event begins padamnya nuclear power station in Fukushima was 40 years old. The tsunami resulted in the failure of a backup generator to turn on the extra cooling power system. Now they face the fear if the cooling process failed, and damaged nuclear core rod.
Professor of Nuclear and Radiation Engineering at the George W. Woodruff School of Georgia Institute of Technology. Glenn E. Sjoden wrote his opinion to CNN. Adapted from CNN, Sjoden believes necessary to make nuclear power safe.
He said currently there is no alternative to non-fossil energy that can create big energy to meet the needs of the world other than nuclear power.
It should be noted, the reactor at Daiichi has didesan as a modern reactor, has no active cooling is needed, and heat from the decay will be eliminated through automatic convection cooling mechanism contained in all modern reactor design. However, only part of the older units require active cooling to remove decay heat.
The use of sea water reactor marks will never again produce a useful electric power for Japan. Because the sea water which resulted in a power chair can not be operated. Overall, these measures contributed but also damage the plant systems.
Furthermore, the radiation is distributed to the public in high doses led to speculation and panic.
Making nuclear power safe
Sjoden assess any incident in Japan this should be a reflection of many, especially the truth that there is no alternative to fossil energy that can make big power to meet needs other than nuclear power.
Sure could use the solar wind, hydropower, biomass and the like. However, collectively, an alternative energy it will use 20 percent of its energy needs. To keep global warming, clean electricity, eliminating the blackout, it can be done with modern nuclear power passively safe with the latest design.
Hopefully, it becomes wisdom everything. nuclear power is necessary for mankind. but, it also makes a threat to human life.
