Nuclear Reactors 109 – Work on US MOX Fuel Fabrication Facility Halted
In the 1960s, it was estimated that there would be a huge global fleet of nuclear power reactors by the year 2000 that would require reprocessing of spent nuclear fuel in order to create more fuel. As the years passed, interest in nuclear power declined and the world reserves of high grade uranium ore increase. When the year 2000 arrived, the global nuclear power reactor fleet turn out to be one tenth of the early estimate and there was sufficient uranium fuel available. Reprocessing of spent fuel to make more fuel is much more expensive than mining and refining uranium. However, there are indications that world uranium production has peaked and that there may be supply problems in the near future. This has spurred renewed interest in breeder reactors and reprocessing with Russia working on a new generation of breeder reactors and reprocessing plants.
In 1999, the U.S. Nuclear Security Administration (NNSA) signed a contract with what is now Shaw Areva MOX Services, LLC. (SAMS). Under the contract, SAMS would design, build and operate a Mixed Oxide (MOX) Fuel Fabrication Facility (MOFFF). This facility would be used to convert plutonium from nuclear weapons into a form that could be used to fuel U.S. nuclear power reactors. To accomplish this, the plutonium would be mixed with uranium oxide to form the fuel pellets used in nuclear reactors. The design would be based on AREVA’s MOX conversion plants in France. The facility was to be constructed at the Savannah River Site operated by NNSA. Under the design, when operational, the facility should be able to convert three and one half metric tons of plutonium into MOX fuel per year.
Currently, most MOX conversion of spent nuclear fuel to recover plutonium is done in the United Kingdom and France with some conversion going on in Russia, India and Japan. China has expressed interest in fast breeder reactors and MOX conversion. With concerns about the world supply of uranium declining, continued use of nuclear power reactors may require increase reprocessing of spent nuclear fuel as well as the use of fast breeder reactors to create plutonium which can then be converted into MOX fuel.
After years of problems at the MOFFF including delays and cost increases, the Obama Administration has decided to halt work on the facility. It was estimated that the reprocessing plant might cost as much as thirty billion dollars over its lifetime. The facility will be put on “cold standby” while the Administration investigates other ways of disposing of or reprocessing spent nuclear fuel from U.S. reactors. Japan has also had a lot of problems with the reprocessing facility that they are working on.
While the intent of MOX creation from weapons grade plutonium is to reduce the amount of weapons grade plutonium in the world, critics have pointed out that during the processing stage, there is an increased risk of theft. There is also the fear that wide use of MOX conversion technology to recover plutonium from spent nuclear fuel which would result in an increase instead of a decrease in the world supply of high grade plutonium, at least during processing. This increases the threat of nuclear proliferation.

Radioactive Waste 65 – Radioactive Fracking Filters in North Dakota
I try not to get too angry when I read about the misdeeds of companies handling radioactive waste but sometimes it is difficult. Many of my blogs focus on the nuclear industry, nuclear reactors and their waste, mining of uranium, nuclear weapons, etc. but today I am going to talk about an industry that at first glance is not related to nuclear issues. I am talking about fracking.
The fracking industry is raping the landscape all over this country, polluting the aquifers and ground water and causing earthquakes, in the quest for cheap natural gas. Although inexpensive natural gas is eroding the support for building more nuclear reactors, one of the waste products in the sludge pumped out of fracking wells consists of natural radioactive uranium in the soil and rock which also contains trace amounts of radium. Radium is very dangerous to biological systems. During fracking operations, there are large cloth filters that capture some of the uranium and radium from fracking operations as waste is pumped out of fracking wells.
North Dakota is home to major fracking operations. An estimated seventy five tons of fracking waste is being pumped out of fracking wells daily in ND. Fracking filters cannot be disposed of in North Dakota landfills if they are emitting more than five picocuries. There are no disposal options in ND for filters emitting more than five picocuries. If companies are caught trying to dispose of such filters in ND landfills, the fine is a thousand dollars a filter. It has been reported that many filters are being improperly disposed of in ND to avoid the cost of shipping them out of state to a legal disposal area.
An Indian reservation found that fracking filters were being tossed into dumpsters and garbage cans on the reservation. Whole flat bed truck trailers full of bags of fracking filters have been found abandoned along ND roads. In the tiny town of Noonan near the Canadian border, old buildings on the property of a closed gas station were found to contain hundreds of bags of highly radioactive fracking filters. The owner of the property is a fugitive wanted on larceny charges. It is unclear whether or not the owner is aware of and complicit in the use his buildings for dumping fracking filters.
The State of North Dakota has no office or staff that is monitoring and attempting to control the illegal dumping of fracking filters in ND. This is a horrible example of an polluting industry moving into a poor state and just doing anything it wants to make a profit. All of the pretty ads about clean cheap natural gas that are appearing on TV are based on a lie. The gas is cheap because the people drilling and operating the fracking wells are dumping the environmental damage and public health threats on the citizens of ND and pocketing the profits from selling the natural gas. If the actual damage to the ecosystem were to be factored into the cost of natural gas, it would not be anywhere near as cheap as is being advertised. I have seen studies that indicate that if the environmental costs of fracked natural gas are factored in, it is no cleaner that burning coal in power plants. The illegal dumping of fracking filters in ND as if it were one big garbage dump is an outrage and if the State of North Dakota cannot afford to stop it, then the Federal government should get involved and prosecute the dumpers.
