 recommended that the best means of protecting the environment and public health and safety would be to dispose of the waste in rock deep underground.

The Department of Energy began studying Yucca Mountain in 1978 to determine whether it would be suitable for the nation's first long-term geologic repository for over 70000 metric tons (68,894.2 LT) (150 million pounds) of spent nuclear fuel and high-level radioactive waste currently stored at 121 sites around the nation. An estimated 10000 metric tons (9,842 LT) of the waste would be from America's military nuclear programs. On December 19, 1984, the Department of Energy selected ten locations in six states for consideration as potential repository sites. This was based on data collected for nearly ten years. The ten sites were studied and results of these preliminary studies were reported in 1985. Based on these reports, President Ronald Reagan

; Deaf Smith County, Texas; and Yucca Mountain. In 1987, Congress amended the Nuclear Waste Policy Act and directed DOE to study only Yucca Mountain, which is already located within a former nuclear test site. The Act provided that if during Site Characterization the Yucca Mountain location is found unsuitable, studies will be stopped immediately. This option expired when the site was actually recommended by the President.

 signed House Joint Resolution 87, allowing the DOE to take the next step in establishing a safe repository in which to store the country's nuclear waste. The Department of Energy was to begin accepting spent fuel at the Yucca Mountain Repository by January 31, 1998 but did not do so because of a series of delays due to legal challenges, concerns over how to transport nuclear waste to the facility, and political pressures resulting in underfunding of the construction.

On July 18, 2006 the DOE proposed March 31, 2017 as the date to open the facility and begin accepting waste based on full funding. On September 8, 2006 Ward (Edward) Sproat, a nuclear industry executive formerly of PECO energy in Pennsylvania, was nominated by President Bush to lead the Yucca Mountain Project.

, a long time opponent of the repository, became the Senate Majority Leader, putting him in a position to greatly affect the future of the project. Reid has said that he would continue to work to block completion of the project, and is quoted as having said: "Yucca Mountain is dead. It'll never happen."

In the 2008 Omnibus Spending Bill, the Yucca Mountain Project's budget was reduced to $390 million. Despite this cut in funding, the project was able to reallocate resources and delay transportation expenditures to complete the License Application for submission on June 3, 2008. Lacking an operating repository, however, the federal government owes to the utilities somewhere between $300 and $500 million per year in compensation for failing to comply with the contract it signed to take the spent nuclear fuel by 1998.

 had the scientific responsibility for post closure analysis and ensuring compliance with the NWPA for one million years. The main tunnel of the Exploratory Studies Facility is U-shaped, 5 mi (8 km) long and 25 ft (7.6 m) wide. There are also several cathedral-like alcoves that branch from the main tunnel. It is in these alcoves that most of the scientific experiments are conducted. The emplacement drifts (smaller diameter tunnels branching off the main tunnel) where waste would have been stored were not constructed since they required a construction authorization by the Nuclear Regulatory Commission. The repository has a statutory limit of 77000 metric tons (84,878 ST). To store this amount of waste requires 40 miles (64.4 km) of tunnels. The Nuclear Waste Policy Act further limits the capacity of the repository to 63000 metric tons (62,004.8 LT) of initial heavy metal in commercial spent fuel. The 104 U.S. commercial reactors currently operating will produce this quantity of spent fuel by 2014, assuming that the spent fuel rods are not reprocessed. Currently, the US has no civil reprocessing plant.

 in the world with the United States having invested US$9 billion on the project. The Department of Energy (DOE) estimates that it has over 100 million U.S. gallons of highly radioactive waste and 2500 metric tons (2,755.8 ST) of spent fuel from the production of nuclear weapons and from research activities in temporary storage. The cost of the facility is being paid for by a combination of a tax on each kilowatt hour of nuclear power and by the taxpayers for disposal of weapons and naval nuclear waste. Based on the 2001 cost estimate, approximately 73 percent is funded from consumers of nuclear powered electricity and 27 percent by the taxpayers.
The latest Total System Life Cycle Cost presented to Congress on July 15, 2008 by Director Sproat is $90 billion. This cost, however, cannot be compared to previous estimates since it includes a repository capacity about twice as large as previously estimated over a much longer period of time (100 years vs 30 years). Additionally, the cost of the project continues to escalate due to the lack of sufficient funding to most efficiently move forward and complete the project. In 2007, the DOE announced it was seeking to double the size of the Yucca Mountain repository to a capacity of 135000 metric tons (148,812 ST), or 300 million pounds.

Opposition

The U.S. Department of Energy was to begin accepting spent fuel at the Yucca Mountain repository by January 31, 1998. However, 12 years after this deadline, the repository at Yucca Mountain is still over a decade away from being opened, and the opening date continues to be delayed.

The project is widely opposed in Nevada and is a hotly debated national topic. A two-thirds majority of Nevadans feel it is unfair for their state to have to store nuclear waste when there are no nuclear power plants in Nevada. Many Nevadans' opposition stemmed from the so-called "Screw Nevada Bill," the 1987 legislation halting study of Hanford and Texas as potential sites for the waste before conclusions could be met. However, the local county in which the proposed facility is located, Nye County, supports the development of the repository.

There was significant public and political opposition to the Yucca Mountain Nuclear Waste Repository project in Nevada. An attempt was made to push ahead with the project and override this opposition. But for large projects which would take decades to complete, there is every chance that sustained local opposition will prevail, and this happened with the Yucca Mountain project. Successful nuclear waste storage siting efforts in Scandinavia have involved local communities in the decision-making process and given them a veto at each stage, but this did not happen with Yucca Mountain. Local communities at potential storage and repository sites "should have early and continued involvement in the process, including funding that would allow them to retain technical experts".

By limiting the compliance time to 10,000 years, EPA did not respect a statutory requirement that it develop standards consistent with NAS recommendations.

EPA's rule

EPA published in the Federal Register a final rule in 2009. The new rule limits radiation doses from Yucca Mountain for up to 1,000,000 years after it closes. Within that regulatory time frame, the EPA has two dose standards that would apply based on the number of years from the time the facility is closed.

For the first 10,000 years, the EPA would retain the 2001 final rule’s dose limit of 15 millirem per year. This is protection at the level of the most stringent radiation regulations in the U.S. today. From 10,000 to one million years, EPA established a dose limit of 100 millirem per year. EPA's rule requires the Department of Energy to show that Yucca Mountain can safely contain wastes, considering the effects of earthquakes, volcanic activity, climate change

 at Yucca Mountain is appreciably fractured and movement of water through an aquifer below the waste repository is primarily through fractures. While the fractures are usually confined to individual layers of tuff, the faults extend from the planned storage area all the way to the water table 600 foot below the surface. Future water transport from the surface to waste containers is likely to be dominated by fractures. There is evidence that surface water has been transported down through the 700 ft (213.4 m) of overburden to the exploratory tunnel at Yucca Mountain in less than 50 years.

Some site opponents assert that, after the predicted containment failure of the waste containers, these cracks may provide a route for movement of radioactive waste that dissolves in the water flowing downward from the desert surface. Officials state that the waste containers will be stored in such a way as to minimize or even nearly eliminate this possibility.

The area around Yucca Mountain received much more rain in the geologic past and the water table was consequently much higher than it is today, though well below the level of the repository.

Earthquakes

 information. Analysis of the available data in 1996 indicates that, since 1976, there have been 621 seismic events of magnitude greater than 2.5 within a 50 miles (80.5 km) radius of Yucca Mountain. Reported underground nuclear weapons tests at the Nevada Test Site have been excluded from this count.

DOE has stated that seismic and tectonic effects on the natural systems at Yucca Mountain will not significantly affect repository performance. Yucca Mountain lies in a region of ongoing tectonic deformation, but the deformation rates are too slow to significantly affect the mountain during the 10,000-year regulatory compliance period. Rises in the water table caused by seismic activity would be, at most, a few tens of meters and would not reach the repository. The fractured and faulted volcanic tuff that Yucca Mountain comprises reflects the occurrence of many earthquake-faulting and strong ground motion events during the last several million years, and the hydrological characteristics of the rock would not be changed significantly by seismic events that may occur in the next 10,000 years.

In September 2007, it was discovered that the Bow Ridge fault line ran underneath the facility, hundreds of feet east of where it was originally thought to be located, beneath a storage pad where spent radioactive fuel canisters would be cooled before being sealed in a maze of tunnels. The discovery required several structures to be moved several hundred feet further to the east, and drew criticism from Robert R. Loux, then head of the Nevada Agency for Nuclear Projects, who argues that Yucca administrators should have known about the fault line's location years prior, and called the movement of the structures “just-in-time engineering.”
In June 2008, a major nuclear equipment supplier, Holtec International, criticized the Department of Energy's safety plan for handling containers of radioactive waste before they are buried at the proposed Yucca Mountain dump. The concern is that, in an earthquake, the unanchored casks of nuclear waste material awaiting burial at Yucca Mountain could be sent into a "chaotic melee of bouncing and rolling juggernauts".

Transportation of waste

The nuclear waste is planned to be shipped to the site by rail and/or truck in robust containers known as spent nuclear fuel shipping cask

s, approved by the Nuclear Regulatory Commission. While the routes in Nevada will be public, in the other states the planned routes, dates and times of transport will be secret for security reasons. State or tribal representatives will be notified before shipments of spent nuclear fuel enter their jurisdictions.

Nevada routes

Within Nevada, the planned primary mode of transportation is via rail through the Caliente Corridor. This corridor starts in Caliente

, Nevada, traveling along the western and northern borders of Nevada for approximately 200 miles (321.9 km). At this point, it turns south.

Other options that are being considered include a rail route along the Mina corridor. This rail route would originate at the Fort Churchill Siding rail line, near Wabuska

, Lida Junction and Oasis Valley. At Oasis Valley, the rail line would turn north-northeast towards Yucca Mountain. Use of this rail corridor by the Department of Energy would require permission from the Walker River Paiute Tribe in order to cross their land. As the first 54 miles (86.9 km) of the proposed corridor is owned by the Department of Defense, additional permission from the DoD would have to be granted.

Impacts

 without any harmful release of radioactive material. This safety record is comparable to the worldwide experience where more than 70,000 metric tons of spent nuclear fuel have been transported since 1970 — an amount approximately equal to the total amount of spent nuclear fuel that would be shipped to Yucca Mountain. However, cities are still concerned about the transport of radioactive waste on highways and railroads that may pass through heavily populated areas. Dr. Robert Halstead, who has been a transportation adviser to the state of Nevada since 1988, stated regarding transportation of the high level waste, "They would heavily affect cities like Buffalo, Cleveland, Pittsburgh, in the Chicago metropolitan area, in Omaha." "Coming out of the south, the heaviest impacts would be in Atlanta, in Nashville, St. Louis, Kansas City, moving across through Salt Lake City, through downtown Las Vegas

, up to Yucca Mountain. And the same cities would be affected by rail shipments as well." Spencer Abraham (DOE) on the other hand has stated, "I think there’s a general understanding that we move hazardous materials in this country, an understanding that the federal government knows how to do it safely."

Cultural impact

Archaeological surveys have found evidence that Native Americans used the immediate vicinity of Yucca Mountain on a temporary or seasonal basis (Stoffle et al. 1990, p. 29). Some Native Americans disagree with the conclusions of archaeological investigators that their ancestors were highly mobile groups of hunter-gatherers who occupied the Yucca Mountain area before Euroamericans began using the area for prospecting, surveying, and ranching. They believe that these conclusions overlook traditional accounts of farming that occurred before European contact.

Cancellation of project

In May 2009, Secretary Steven Chu stated:

"Yucca Mountain as a repository is off the table. What we're going to be doing is saying, let's step back. We realize that we know a lot more today than we did 25 or 30 years ago. The NRC is saying that the dry cask storage at current sites would be safe for many decades, so that gives us time to figure out what we should do for a long-term strategy. We will be assembling a blue-ribbon panel to look at the issue. We're looking at reactors that have a high-energy neutron spectrum that can actually allow you to burn down the long-lived actinide

 waste. These are fast-neutron reactors. There's others: a resurgence of hybrid solutions of fusion fission where the fusion would impart not only energy, but again creates high-energy neutrons that can burn down the long-lived actinides. ...


"Some of the waste is already vitrified. There is, in my mind, no economical reason why you would ever think of pulling it back into a potential fuel cycle. So one could well imagine—again, it depends on what the blue-ribbon panel says—one could well imagine that for a certain classification for a certain type of waste, you don't want to have access to it anymore, so that means you could use different sites than Yucca Mountain, such as salt dome

s. Once you put it in there, the salt oozes around it. These are geologically stable for a 50 to 100 million year time scale. The trouble with those type of places for repositories is you don't have access to it anymore. But say for certain types of waste you don't want to have access to it anymore—that's good. It's a very natural containment. ...whereas there would be other waste where you say it has some inherent value, let's keep it around for a hundred years, two hundred years, because there's a high likelihood we'll come back to it and want to recover that.


"So the real thing is, let's get some really wise heads together and figure out how you want to deal with the interim and long-term storage. Yucca was supposed to be everything to everybody, and I think, knowing what we know today, there's going to have to be several regional areas."


In July 2009, the House of Representatives voted 388 to 30 on amendments to HHR3183 to not defund the Yucca Mountain repository in the FY2010 budget.
