The Foreign Americium Disposal and Storage Act of 2025 (FADS Act) would codify a disposal pathway for certain foreign-origin americium-241 sources at the Waste Isolation Pilot Plant (WIPP). The bill finds that US-origin Am-241 sealed sources can already be disposed at WIPP, while corresponding Russian-origin sources are not currently eligible.
It would add a new provision to the NDAA for FY2005 to authorize the collection, storage, and safe disposal of these materials at WIPP for purposes of disposal, once they meet the Waste Acceptance Criteria. The result would be a clearer, codified process to move foreign-origin Am-241 from use to disposal, with an estimated disposal volume of about 1 to 2 shipments per year and a goal of accelerating removal and reducing material that could be misused in a radiological dispersal event.
At a Glance
What It Does
Adds a new NDAA-based authority to collect, store, and dispose of certain foreign-origin fissile or radiological materials at WIPP for disposal. It defines the materials and sets the disposal pathway.
Who It Affects
DOE/NNSA program offices, WIPP and its Carlsbad facility, NRC for regulatory alignment, and facilities that generate or store foreign-origin Am-241 sources.
Why It Matters
Provides a formal disposal route for potentially proliferation-attractive materials, aligning defense nonproliferation goals with a secure disposal pathway at a dedicated facility.

What This Bill Actually Does
The bill formalizes a disposal route for certain foreign-origin americium-241 sources at the Waste Isolation Pilot Plant (WIPP). It revises the Reagan NDAA of 2005 by adding a new provision that covers collection, storage, and safe disposal of these materials at WIPP for the purpose of disposal.
The aim is to ensure that materials with proliferation risk can be removed from circulation through a defined, federally authorized process rather than remaining in scattered storage or transit. The bill’s findings emphasize that US-origin Am-241 sources are eligible for disposal at WIPP, while Russian-origin sources are not, and it recommends that Russian-origin sealed sources meeting WIPP criteria should become eligible as well.
It notes that the expected disposal volume is small (roughly 1–2 shipments per year) and that codifying this pathway would accelerate removal and reduce the availability of material that could be used in a dirty bomb. By codifying the disposal pathway, the bill seeks to streamline cooperation among DOE, NNSA, NRC, and WIPP facilities to manage foreign-origin materials securely and efficiently.
The Five Things You Need to Know
The bill adds a new subparagraph to NDAA 2005 to authorize disposal of certain foreign-origin Am-241 at WIPP.
Foreign-origin Am-241 is identified as a material of proliferation concern and is to be disposed under a codified pathway.
Russian-origin sealed Am-241 sources meeting WIPP criteria would become eligible for disposal at WIPP.
Estimated disposal volume is 1–2 shipments per year, with negligible impact on WIPP operations.
The bill leverages the NNSA’s source recovery programs to accelerate removal and reduce proliferation risk.

Short title
This Act may be cited as the Foreign Americium Disposal and Storage Act of 2025 (FADS Act of 2025). It creates the formal name and boundary for the statute analyzed here.
Findings supporting disposal at WIPP
Congress identifies several policy rationales: US-origin Am-241 can already be disposed at WIPP, while Russian-origin Am-241 is not; WIPP is designated for radioactive waste from atomic energy defense activities; Am-241 sources of concern often sit near eligible sources; Russian-origin sealed sources meeting WIPP criteria should be eligible; the projected disposal volume is small and will have a negligible impact on WIPP operations; there is broad international emphasis on protecting Am-241 due to potential misuse; and codifying a disposal pathway will accelerate removal of sources recovered by NNSA, reducing proliferation risk.
Clarification of NDAA authority
The bill adds a new subparagraph to Section 3132(c)(1) of the NDAA for FY2005. The new provision authorizes the collection, storage, and safe disposal of materials described as waste materials generated by atomic energy defense activities for the purpose of disposal at WIPP. It defines the materials as proliferation-attractive fissile or radiological materials that contain transuranic elements of foreign-origin and, but for the foreign-origin component, are similar to other materials covered by this section. This creates a formal, codified pathway for such materials to be disposed at WIPP once they meet relevant waste acceptance criteria.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- DOE and NNSA program offices for accelerated disposal and nonproliferation goals
- WIPP site operators and Carlsbad Field Office staff responsible for handling and processing disposal
- NRC for regulatory alignment and oversight implications
- Facilities and industries that generate or store foreign-origin Am-241 sealed sources (e.g., specific medical, industrial, or research facilities)
- U.S. defense and nonproliferation communities seeking to reduce stockpiles of proliferation-prone materials
Who Bears the Cost
- DOE/NNSA program offices incur costs to implement and monitor the disposal pathway
- WIPP operators may face incremental logistics and processing costs and requirement to ensure acceptance criteria compliance
- NRC resources may be allocated for additional regulatory oversight and guidance
- Facilities generating foreign-origin Am-241 sources bear disposal and handling costs to comply with the new pathway
- Transport and security costs associated with moving sources to disposal at WIPP
Key Issues
The Core Tension
The central tension is between creating a secure disposal pathway for potentially proliferation-prone foreign-origin Am-241 and maintaining strict safeguards around such materials while expanding a disposal program at a dedicated facility that has limited capacity and a specific mission.
The bill creates a tightly scoped change that expands a disposal pathway for a narrow class of materials—foreign-origin Am-241 sealed sources—without broadening WIPP’s mission or capacity. The primary policy tension lies in balancing nonproliferation concerns with the operational realities and costs of additional disposal activities at WIPP.
While the volume is described as modest (1–2 shipments per year), the bill raises implementation questions about how facilities verify foreign-origin status, ensure proper packaging and acceptance into WIPP, and coordinate among federal agencies (DOE, NNSA, NRC) and the WIPP site. There is also a need to ensure that such disposal does not inadvertently lower the safeguards around materials that could be misused.
The NDAA amendment’s language hinges on precise definitions of which materials qualify and how they are verified against WIPP’s acceptance criteria, leaving room for future regulatory choreography and potential updates as material inventories evolve.
