Stanford Energy is brought to you by the Precourt Institute for Energy

The U.S. government has worked for decades and spent tens of billions of dollars in search of a permanent resting place for the nation’s nuclear waste. Some 80,000 tons of highly radioactive spent fuel from commercial nuclear power plants and millions of gallons of high-level nuclear waste from defense programs are stored in pools, dry casks and large tanks at more than 75 sites throughout the country.

A Stanford University-led study recommends that the United States reset its nuclear waste program by moving responsibility for commercially generated, used nuclear fuel away from the federal government and into the hands of an independent, nonprofit, utility-owned and -funded nuclear waste management organization.
“No single group, institution or governmental organization is incentivized to find a solution,” said Rod Ewing, co-director of Stanford’s Center for International Security & Cooperation and professor of geological sciences.
The three-year study, led by Ewing, makes a series of recommendations focused on the back-end of the nuclear fuel cycle. The report, Reset of America’s Nuclear Waste Management Strategy and Policy, was released December 10.
A tightening knot
Over the past four decades, the U.S. nuclear waste program has suffered from continuing changes to the original Nuclear Waste Policy Act, a slow-to-develop and changing regulatory framework. Erratic funding, significant changes in policy with changing administrations, conflicting policies from Congress and the executive branch, and – most important – inadequate public engagement have also blocked any progress.
“The U.S. program is in an ever-tightening Gordian knot – the strands of which are technical, logistical, regulatory, legal, financial, social and political – all caught in a web of agreements with states and communities, regulations, court rulings and the congressional budgetary process,” the report says.
The project’s steering committee sought to untangle these technical, administrative and public barriers so that critical issues could be identified and overcome. They held five open meetings with some 75 internationally recognized experts, government officials, leaders of nongovernmental organizations, affected citizens and Stanford scholars as speakers.
After describing the Sisyphean history of the U.S. nuclear waste management and disposal program, the report makes recommendations all focused around a final goal: long-term disposal of highly radioactive waste in a mined, geologic repository.
"Most importantly, the United States has taken its eyes off the prize, that is, disposal of highly radioactive nuclear waste in a deep-mined geologic repository,” said Allison Macfarlane, a member of the steering committee and a professor of public policy and international affairs at George Washington University. “Spent nuclear fuel stored above ground – either in pools or dry casks – is not a solution. These facilities will eventually degrade. And, if not monitored and cared for, they will contaminate our environment."
Q&A: What should we do with nuclear waste?
“The utilities package and store the fuel in ways that are economical from their perspective, but the result may well be packages that are unsuitable for transportation and disposal. In other words, there is a huge disconnect in the backend of the nuclear fuel cycle in the U.S. Our proposal to put the utilities in charge of the handling, transportation and disposal of the fuel removes many of these disconnects.”

The new, independent, utility-owned organization would control spent fuel from the time it is removed from reactors until its final disposal in a geologic repository. This is not a new idea. Finland, Sweden, Switzerland and Canada all have adopted a similar approach – and their nuclear waste management programs are moving forward. Finland expects to receive its first spent fuel at its geologic repository on the island of Olkiluoto in the mid-2020s.
“Initially, I was skeptical about placing utilities with nuclear power plants in control of the spent fuel from commercial reactors” said Ewing. “But as we discussed the advantages of this cradle-to-grave approach, I was persuaded, particularly because this is the approach taken by other successful programs.”
Essential to the success of a new organization would be access to the Nuclear Waste Fund. Reassigning responsibility to a new organization – whether controlled by the federal government or nuclear utilities – would require an act of Congress. The report recommends that the Nuclear Waste Fund, more than $40 billion, be transferred to the new organization over several decades. If the new organization successfully develops a geologic repository, this repository could also be used for highly-radioactive defense waste.

• Public engagement is critical. The new organization would be required to work with all interested parties: local, state and tribal governments, as well as public interest groups, industry, academia and regulators to ensure that all relevant views become part of the overall strategy for dealing with waste. Further, local communities, states and tribes should have a well-defined opportunity to say “No” to a geologic repository.
• Local communities, Native American tribes and states should receive funding to conduct their own reviews of the strategy and safety of a site.
• The new organization should focus on removal of spent fuel from plants that have been shut down first, instead of the oldest fuel. The ability to fully decommission shutdown plants would save hundreds of millions of dollars.
• A new approach, “the safety case,” should be used by regulators. The safety case should be developed during the early stages of repository site investigations and updated regularly as additional information is incorporated and as comments from stakeholders are received. The safety case is in essence a compelling argument for the safety of the selected site.
• An essential step in building trust and ensuring that the safety case is adequate is through formal peer review. The report recommends an independent, internationally-based peer review of the safety case. Sweden, Switzerland, and France, have conducted such an independent review through the Nuclear Energy Agency’s international expert group.
“The status quo is a big liability for the future of nuclear power, an established source of carbon-free electricity,” said Sally Benson, co-director of Stanford’s Precourt Institute for Energy and a member of the report’s steering committee. “These recommendations will, I hope, break the gridlock in Washington and prompt concrete action to solve this problem.”
Benson is also a professor of energy resources engineering. She and Ewing are members of Stanford’s School of Earth, Energy & Environmental Sciences. Members of the project’s steering committee also include affiliates of Vattenfall, Ecole des Mines de Nantes, the U.S. Nuclear Waste Technical Review Board, the French Embassy in Beijing, ENVIRON, and the Nuclear Waste Management Organization in Canada.
