Nuclear Portfolio at ARPA-E Jenifer Shafer March 30, 2023

Fission

- MEITNER (2018)

Can we greatly reduce AR CapEx?

- GEMINA (2020)

Can we greatly reduce AR OpEx?

- ONWARDS (2021)

Can we greatly minimize the disposal impact of AR wastes?

- CURIE (2022)

Can we improve the cost and monitoring of UNF (used nuclear fuel) reprocessing?

ARPA-E Advanced Nuclear Fission Portfolio 2

March 30, 2023 Attentive to commercialization & deployment

~$160M overall investment Transmutation

- Transmutation Active area of program development Nuclear l ARPA-E

MEITNER (Modeling-Enhanced Innovations Trailblazing Nuclear Energy Reinvigoration) 3 Nuclear l ARPA-E March 30, 2023 Goal: Develop and demonstrate technologies that greatly improve advanced reactor performance Metric Units State-of-the-Art Overnight construction cost

$/We 2-7 On-site construction time Months

> 60 Total staffing level (on-site & off-site)

FTE/GWe 450-750 Emergency planning zone (EPZ)

Miles 10 and 50 Time before human response required for an accident Days 3

Onsite backup power kWe

> 0 kW Ramp rate without steam bypass power capacity/min 5%

Process heat temperature

ºC N/A MEITNER is supporting transformative technologies for AR plant designs that simultaneously achieve:

Low overnight construction cost Largely autonomous operations to staffing level Safety when considering time before intervention in an accident potential for public exposure to radiation Very short on-site construction time Proliferation resistance via safeguards by design The ability to achieve either or both:

easy electrical grid integration with intermittent sources such as wind and solar availability to provide economical industrial process heat

GEMINA (Generating Electricity Managed by Intelligent Nuclear Assets) 4 March 30, 2023 Goal: Develop the tools and cost basis for ARs to achieve fixed O&M costs of

$2/MWh without shifting costs to other parts of LCOE Awardee teams are developing the following for one or more of the most promising AR designs:

Digital twins for advanced reactor systems Relevant cyber physical systems O&M approaches for advanced reactors Cost models and design updates Nuclear l ARPA-E

ONWARDS (Optimizing Nuclear Waste and Advanced Reactor Disposal Systems)

Goal: Develop technologies to significantly minimize the disposal impact of wastes from ARs while maintaining disposal costs in the range of $1/MWh 5

Nuclear l ARPA-E March 30, 2023 ONWARDS seeks to support the development of technologies that enable:

10x reduction in waste volumes or repository footprint with no weakening of safeguards standards Better than 1% accuracy in fissile mass measurement in UNF processing in high-radiation backgrounds Improving proliferation resistance of U and TRU materials recycling No pure fissile material streams produced during processing (< 0.1% actinides by mass in waste streams)

High performance waste forms for AR HLW across multiple disposal environments.

The production of new waste streams is required to be minimal relative to a once-through fuel cycle and have an established path to a robust waste form or final disposition.

CURIE (Converting UNF Radioisotopes Into Energy)

Global Metrics 1.

significantly (i.e.,

at least an order of magnitude) reduce the volume of LWR HLW requiring permanent

disposal, 2.

maintain disposal costs in the range of 0.1¢/kilowatt-hour (kWh)4, 3.

provide a 1¢/kWh5 fuel cost for a 200 metric tons heavy metal (MTHM)/yr nth-of-a-kind (NOAK) facility, 4.

in situ SNM process monitoring approaches that predict, within 1%

uncertainty and under representative conditions, the post-process material accountancy, and 5.

development of UNF separations which do not produce pure plutonium streams 6

Nuclear l ARPA-E March 30, 2023 Goal: Enable commercially viable reprocessing of used nuclear fuel (UNF) from the current light water reactor (LWR) fleet by resolving key gaps/barriers in reprocessing technologies, process monitoring, and facility design
