NHK Documentary: Nuclear Waste Managing a Lethal Legacy
It's been about 2 years since the accident. Nuclear power plants across the country still store huge amounts of spent fuel. No one has found a way to deal with the spent fuel. Nor no sites have been found for its final disposal. The spent fuel kept piling up. It now amounts to 17 thousand tons for Japan as a whole. Some nuclear plants could run out of storage space in about 2 years if they were to go back online. What can be done about this nuclear waste which has nowhere to go? We'll explore several paths to resolving this critical issue.

21m- reprocessing plants in Europe issues

29- in Switzerland
Dried steel casked storage space is used to store spent fuel rods after being cooled.
The container completely shuts radiation and doesnt need electricity.  Switzerland is planning to store in this way for 40 years until they build the final disposal site.

Japanese regulation is required all the spent fuel need to be reprocessed.  So we cant dispose the spent fuel in the disposal place like it is in Switzerland.  Rokkashomura have been encountering many problems and its not been full scale of operation.  Consequently number of spent fuel have been piling up throughout the nations.  Even the disposal site is being built; the regulation will prohibit it to store without reprocessing.  Unless Rokkashomura being operated nuclear business will be affected.  So all spent fuel needs to be reprocessed.  Reprocessing plant is to separate fuel and radioactive waste.

The extracted fuels from the reprocessing plant would be multiplied in the fast breeder reactor and be recycled repeatedly. It was to be a dream nuclear fuel cycle for unlimited power to produce for resourced poor Japan.

In 1995 Monju Fast Breeder reactor sodium leak accident occurred.  Since then it has been stopped operating.  The reactor never be operational.  The plan came to a dead end.  we can't deceipt the public any more.  A person engaged in Japans energy policy granted our interview.  Some people estimated that running of reprocessing plant would cost 11 trillion (paid by ratepayers) yen for 40 years running following the start of the operation. We knew the fast breeder reactor would not be completed e conomically and politically a meaningless to continue.  JNS was established by electric power companies. 
some shareholders in Tepco started to feel doubtful  Rokkasho was too costly.  Why the Japanese government and power companies continued the project.  Spent fuel from many different areas already had sen to the recycled plants.  If reprocessing plant halted then spent fuel material won't be recycled. and the Aomori government is entitled to send back spent fuel if that happened. The power plants would be overwhelmed with returned fuel.  Maybe they are forced to suspend their operations.  We learned this from the former TEPCO director.  Nuclear power plants won't be able to operate if we processing is abandoned.  .  As far as they are concerned reprocessing is a matter of life or death.  Talks were held between government and power companies.  Both sides agreed to place a priority of continuing the nuclear power program regardless of the reprocessing plants costs.  The expensive reprocessing plants revived.  Power companies and the Ministry of economy, trade and industry failed to agree on a frame work to eliminate huge financial burden placed on the public.  We couldnt face a fact that we created that such expensive white elephant.
Then the issue resurfaced after the Fukushima nuclear accident..
Last year the government reviewed the reprocessing project.   The Aomori government, Miura issued a vigorously protest.  
"We are worry that spent fuel will remain in Aomori.  This is not what we agreed on.  If its not going to be reprocessed it must be returned.  Aomori is not a dumping ground for nuclear waste."  
 The government decided not to change the policy.  In the back ground with the conflicting interests of the parties involved.

The Atomic Energy Commission hold 23 closed meetings after the Fukushima accident.  Even as the government reviewed the policy, JNFL, ministry of trade and industry, Tepco company, cabinet office officers and Atomic Energy Commission were meeting to discuss the issue.  
Cabinet Office official:  You have to be running the reprocessing plant, right? 
JNJL:  thank you for understanding.
Cabinet office official: Well then, that's it.  We can't work out a plan to shut down Rokkasho. 
(JNFL handed up this material at the meeting. The firm had accumulated 1 trillion yen in debt.  The company official stressed that if the processing program would stop, they will no longer be able to borrow money, and could face a financial crisis.)
JNFL: A private firm can't withstand such a crisis.  We need some sort of assistance
JNFL: We'll need around 300 billion yen a year
JNFL:  If we were a government-owned entity, we could stop reprocessing right away
JFEC:  Exactly. 
JNFL: Private companies get into trouble if the money stops flowing.
JNEC:  You mean the banks will stop lending
JNFL: Closing Rokkasho means everything will stop.  Please prevent that from happening somehow.

We asked JNFL(Japan Nuclear Fuel Ltd.) about the meeting. 
This is an outline of their response:  JNFL was established as an privat e company and has been preparing to start up a reprocessing plant based on the national policy.  If the policy suddenly changes we need to take steps.  We will explain the facts that commonly perspective. 
Generally speaking stopping the project will have negative financial effect on both minispunies  and electric companies.   

The Atomic Energy Commision  vice chairman, Mr. Suzuki attended the meeting.  He agreed to interview.  He said that the commission must be neutral. and  acknowledged that the close meeting should not be held.  He explained why the reprocessing program wont be changed.  invested interest (利害関係) are the main concern. Many businesses are counted on successful outcome for the planned nuclear fuel cycle.   they don't want to see the changes that could affect their business.  Mr. Suzuki will feel difficult to talk about the changes with things as they are now.  We should first discuss the policy and decide on feasible solution.  Then think about Rokkasho.  Country 50 year old nuclear energy policy, systems and organizations are standing in the way of change.  The situation limits what we can do.  Even many people realized that the reprocessing won't work, the project continues.  The reprocessing program was supposed to give resource poor Japan unlimited supply of energy.  But as the time passed it became simply tool of nuclear power plant running and protect the businesses involved. Other factors influence the decison as well.  These include possible harm to local economy and  potential damage to relation to the United States... which is ....  But changing the current frame work is only way forward.  
Now we know the danger of radioactive waste, we can't keep to put it away. 
But we can't allow this to go on..... 
(Editors note: Maintenance cost of Rokkasho (Reprocessing plant) is 1.8 million a day.)
