News: Japan Halted New Nuclear Reactor

FIGURE 1: Japan nuclear reactor current status by www.nuclear-org.co

On 1 disember 2011, Dailyonline Yumiuro reported that TEPCO is giving up new reactor at its Higashidori plant in notherm Japan due to financial difficulties after Fukushima crisis.. In fact, no companies have publicly announced they are giving up construction of planned new units. Therefore, TEPCO denied the Yumiuro report. The new nuclear reactor however, expected to start operation in March 2017 but been halted following the radiation crisis.

Currently Japan having issued with new energy policies. Japan Prime Minister predecessor Naoto Kwan, vowed Japan to off nuclear power and calling for a review of plans to boost nuclear capacity to meet over half of electricity demand by 2030. With nuclear reactor shut down for further inspection make Japan leak of power supply which is currently having 1/3 of maximum capasity(maximum=49, 110 megawatts). Only 16 reactors are running while other undergo a regular check up every 13 month.

The rise of nuclear radiation is now bring Japan in the tough road. They on the way on proposed new alternative which is renewable energy to replaced nuclear position. Some how this renewable energy cost higher price compared to nuclear. So, can Japan manage to pursue their effort in blocking nuclear energy by transform their energy production toward renewable energy with rise of electricity price? Do public willing to pay more which is double than current price ? It is an typical question to ask when it come to money. I think Japan need to overview their plan deeper and details to avoid troublesome in future.

China will grow larger

While we are still looking into nuclear as energy sources, China - a big player in both energy and economic power take a large step to go ahead with nuclear. Their target consist of three stages :-

  • by 2030 - Fast Breed Reactor (FBR) in combination of Pressurized Water Reactor (PWR) will produce 200GWe
  • around 2050 - combination of FBR and PWR output are expected to be doubled up to 400GWe 
  • by 2100 - full replacement of fossil power plant and electricity are generated by means of nuclear plant instead. The expected output is 1500GWe
To achieve this target, China are looking into some new experimental design like Chinese Experimental Fast Reactor (CEFR) which utilize fast neutron instead - which means neutron doesn't need to be slow down first to achieve a controllable reaction and desired power output like Generation II and III reactors. Some other alternative reactors that China still looking into are:- 
  • Chinese Demonstration Fast Reactors (CDFR) - similar to OKBM Afrikantov design. It uses ceramic MOX pallets fuel (breeding ratio of 1.2).
  • Chinese Demonstration Fast Breed Reactors (CDFBR) - uses U-Pu-Zr fuel which has higher burn up and breeding ratio of 1.5. These are Generation IV reactors. 

So, looks like China is one step ahead to achieve a higher score in never-ending global energy race. With it's current economic growth, energy hunger on such a large scale is already expected. Let's hope we can catch up fast.
