How a HALEU bank could work

Lack of a long-term, reliable source of high-assay low-enriched uranium (HALEU) fuel represents a critical risk to the deployment of advanced reactors, which could be a key source of carbon-free electricity in the future. However, a HALEU fuel bank could resolve the conundrum facing advanced reactor developers and potential HALEU fuel suppliers by supporting the production of HALEU for advanced reactors and resolving the uncertainty faced by reactor developers and their potential customers and sources of financing.

Searching for the missing link: Options for firm zero-carbon power

“Firm” zero-carbon generation resources, which are not necessarily intended to run all the time, but can be available at any time, will be needed to complement renewable resources in the future, without emitting the CO2 produced by today’s fossil energy system. These resources might include, for example, fossil-fuel power plants with carbon capture, nuclear power plants with improved dispatchability, geothermal power, and bio-fueled generators. But the path to developing, and certainly deploying, such resources has been slower and more fraught than for renewables; these “firm” electricity generation resources represent a missing link in the path towards a decarbonized electricity grid.

Most recently, he served in senior finance roles, including as chief financial officer for Centrus Energy, a public company engaged in the sale of nuclear fuel and the development of nuclear enrichment technology. He led strategy for Progress Energy, an investor-owned electric utility, and served as practice-area leader for the consultant Pace Global Energy focused on energy markets and risk management. He arranged project financing for PG&E National Energy Group (US Generating Company), a leading independent-power developer and energy trader, and subsequently developed the company’s power market outlook to support project development. Early in his career, he worked at the US Environmental Protection Agency on air-pollution rules. He holds a masters in public policy from the Harvard Kennedy School and a BA in physics from Princeton University.
