Consent-Based Siting Consortia flyer
Consent-based siting is an approach that seeks communities’ willing and informed consent to accept new development or host a project in their area. The U.S. Department of Energy (DOE) is using a consent-based siting process to identify one or more federal consolidated interim storage facilities for the nation’s spent nuclear fuel, a byproduct of nuclear power generation. Spent nuclear fuel is currently stored at more than 70 sites across the country in communities that did not agree to host the material long term.

What is Consent-Based Siting?
Consent-based siting is an approach that seeks the willing and informed consent of people and communities to host a project in their area. This process is designed to be flexible, adaptive, and responsive to community concerns.
How is DOE using Consent-Based Siting? How can people and communities participate?
Atlas Railcar factsheet
Atlas Railcar factsheet
The U.S. Department of Energy (DOE) is developing special railcars for future large-scale DOE transport of spent nuclear fuel (SNF) from nuclear power plants. Designs include new buffer railcars, the Atlas railcar (to transport SNF containers), and a new escort railcar for security personnel that was developed in collaboration with the U.S. Navy. All railcars are expected to complete testing and meet North American freight safety standards in 2023.

5 Common Myths about Transporting Spent Nuclear Fuel flyer
Despite being safely transported in the U.S. for more than half a century, many still believe spent nuclear fuel (SNF) is too dangerous to transport. But, in reality, it’s a well-coordinated process with a great track record—and we have the facts to prove it.

Consent-Based Siting: U.S. DOE Climate Action & Spent Nuclear Fuel Management
Consent-Based Siting: U.S. DOE Climate Action & Spent Nuclear Fuel Management
Nuclear energy is essential to tackling climate change. Maintaining the nation’s current fleet and deploying advanced reactors is crucial in achieving the U.S. Department of Energy (DOE)’s ambitious goals of a 50% reduction in carbon emissions by the end of the decade, 100% clean electricity by 2035, and a net-zero economy by 2050.
However, to meet those goals, progress needs to be made in the management of spent nuclear fuel. Inaction on this issue has already cost taxpayers more than $9 billion in settlements and judgments.

Consent-Based Siting: Social Science & Nuclear Waste Management at the U.S. Department of Energy
Can anthropologists help the U.S. Department of Energy (DOE) design a more environmentally just, participatory, and consent-based siting process for spent nuclear fuel management facilities? The DOE has committed to a consent-based approach to siting spent nuclear fuel management facilities that aims to enable broad community participation and center equity and environmental justice.
Spending Time on Spent Nuclear Fuel
Spending Time on Spent Nuclear Fuel
Making progress on the long-term management of spent nuclear fuel can be fraught with political and economic challenges, but groups within the U.S. are looking to try and tackle the challenge from many different angles. As the government ramps up efforts to support spent nuclear fuel management up to the limits of the law, ANS and others are making recommendations around, and receiving funding oriented to, pathways for progress.

Validation of SCALE-4 for Burnup Credit Applications
Validation of SCALE-4 for Burnup Credit Applications
In the past, criticality analysis of pressurized water reactor (PWR) fuel stored in racks and casks has assumed that the fuel is fresh with the maximum allowable initial enrichment. If credit is allowed for fuel burnup in the design of casks that are used in the transport of spent light water reactor fuel to a repository, the increase in payload can lead to a significant reduction in the cost of transport and a potential reduction in the risk to the public. A portion of the work has been performed at Oak Ridge National Laboratory (ORNL) in support of the U.S.

Regulatory Perspective on Potential Fuel Reconfiguration and Its Implication to High Burnup Spent Fuel Storage and Transportation
The recent experiments conducted by Argonne National Laboratory on high burnup fuel cladding material property show that the ductile to brittle transition temperature of high burnup fuel cladding is dependent on: (1) cladding material, (2) irradiation conditions, and (3) drying-storage histories (stress at maximum temperature) [1]. The experiment results also show that the ductile to brittle temperature increases as the fuel burnup increases.

Fission Product Experiment Program: Validation and Calculational Analysis
From 1998 to 2004, a series of critical experiments referred to as the fission product (FP) experimental program was performed at the Commissariat à l'Energie Atomique Valduc research facility. The experiments were designed by Institut de Radioprotection et de Sûreté Nucléaire (IRSN) and funded by AREVA NC and IRSN within the French program supporting development of a technical basis for burnup credit validation.

Issues for Effective Implementation of Burnup Credit
Issues for Effective Implementation of Burnup Credit
In the United States, burnup credit has been used in the criticality safety evaluation for storage pools at
pressurized water reactors (PWRs) and considerable work has been performed to lay the foundation for use of
burnup credit in dry storage and transport cask applications and permanent disposal applications. Many of the
technical issues related to the basic physics phenomena and parameters of importance are similar in each of these
applications. However, the nuclear fuel cycle in the United States has never been fully integrated and the

Cross-Checking of the Operator Data Used for Burn Up Measurements
Cross-Checking of the Operator Data Used for Burn Up Measurements
Taking into account of the loss of reactivity of fuels at the end of their irradiation is known under the
term burnup credit (BUC). It is a question of dimensioning in a less penalizing way the devices of transport,
storage or of processing with respect to the risk of criticality. In the context of nuclear criticality safety a better
realism cannot be obtained at the price of conservatism. As a result the regulator requires measurements make it
possible to validate the adequacy between real fuels and the design assumptions. The sophistication of the
