Socio-technical multi-criteria evaluation of long-term spent nuclear fuel management strategies: A framework and method

François Diaz-Maurin, Jerold Yu, Rodney C. Ewing
Science of The Total Environment , 2021
In the absence of a federal geologic repository or consolidated, interim storage in the United States, commercial spent fuel will remain stranded at some 75 sites across the country. Currently, these include 18 “orphaned sites” where spent fuel has been left at decommissioned reactor sites.

Probabilistic Performance Assessment vs. the Safety Case Approach

François Diaz-Maurin, Rodney C. Ewing
MRS Advances , 2019

The “safety case” approach has been developed to address the issue of evaluating the performance of a geologic repository in the face of the large uncertainty that results for evaluations that extend over hundreds of thousands of years. This paper reviews the concept of the safety case as it has been defined by the international community. We contrast the safety case approach with that presently used in the U.S. repository program. Especially, we focus on the role of uncertainty quantification.

Evolution and Structure of the Scientific Basis for Nuclear Waste Management

François Diaz-Maurin, Rodney C. Ewing
MRS Advances , 2018

The final disposal of nuclear waste is at the interface between the technologies of the nuclear fuel cycle that produce the waste and the natural hydrologic and geochemical cycles of geologic repositories. Despite this broad interdisciplinary scope, nuclear waste management, as practiced, remains “balkanized” among the relevant disciplines.

Mission Impossible? Socio-technical Integration of Nuclear Waste Geological Disposal Systems

François Diaz-Maurin, François Diaz-Maurin, Rodney C. Ewing
Sustainability , 2018

Abstract: We present a new perspective on geological disposal systems for nuclear waste. Geological disposal systems encompass all the processes required for the permanent isolation of highly-radioactive materials from humans and the biosphere. Radioactive materials requiring geological disposal are created by commercial nuclear power plants, research reactors, and defense-related nuclear activities, such as spent nuclear fuel from commercial reactors and high-level waste from reprocessing to reclaim fissile material for weapons.

Scarcity in abundance: the challenges of promoting energy access in the Southern African region

François Diaz-Maurin, Zivayi Chiguvare, Gideon Gopee
Energy Policy , 2018

Abstract: The paper deals with the challenges of energy access, efficiency and security as essential conditions to improve people's living in the Southern African region. It supports energy policies by providing material for an integrated assessment of alternative energy systems at national level.

Chronic long-term risk of low-level radiation exposure: Bridging the lay/expert divide

François Diaz-Maurin, François Diaz-Maurin
Bulletin of the Atomic Scientists , 2018

Abstract: The failure of experts and lay people to understand each other has been fueling conflict around the environmental clean-up of the many sites in the United States that are contaminated by the nuclear weapons program. This mutual distrust was exacerbated by the culture of secrecy surrounding the atomic weapons program during World War II, and later by the innate culture of bureaucracy in the federal agencies that have sprung up since then.

Atomic Homefront: a film about struggling to live with Manhattan Project radioactive waste

François Diaz-Maurin, François Diaz-Maurin
Bulletin of the Atomic Scientists , 2018

Abstract: This commentary reviews and discusses HBO’s new documentary, Atomic Homefront, which shows how communities are still struggling to live with radiation from radioactive waste generated more than 70 years ago during the race to build the atomic bomb—part of a secret government effort during World War II known as the Manhattan Project.
