Summary
The U.S. government must manage high-level radioactive waste but is failing. A new perspective is offered on the Blue Ribbon Commission
Area of Science:
- Environmental Science
- Nuclear Engineering
- Public Policy
Background:
- The U.S. government is legally obligated to manage high-level radioactive waste from both defense and civilian nuclear power generation.
- Current waste management strategies are not meeting this federal obligation.
- The Blue Ribbon Commission's 2012 report offers guidance but lacks novel solutions.
Purpose of the Study:
- To provide a critical perspective on the Blue Ribbon Commission's recommendations for nuclear waste management.
- To propose a viable path forward for fulfilling the U.S. government's obligation in managing radioactive waste.
- To analyze the challenges and offer insights based on extensive experience with nuclear waste technical review.
Main Methods:
- Analysis of the U.S. government's high-level radioactive waste management obligations.
- Review and critique of the January 2012 Final Report from the Blue Ribbon Commission on America's Nuclear Future.
- Leveraging historical experience from service on the Nuclear Waste Technical Review Board and the National Research Council's Board on Radioactive Waste Management.
Main Results:
- The Blue Ribbon Commission's report, while commendable, does not introduce significantly new approaches to radioactive waste management.
- A persistent challenge remains in establishing a long-term, stable solution for nuclear waste disposal, likened to the myth of Sisyphus.
- The author's perspective highlights the need for a breakthrough strategy to ensure waste containment.
Conclusions:
- Progress in U.S. high-level radioactive waste management requires innovative solutions beyond incremental guidance.
- A sustained effort is needed to overcome the cyclical failures in waste management, ensuring long-term security.
- The nation must find a definitive solution to permanently manage its nuclear waste legacy.

Nuclear Transmutation
Nuclear transmutation is the conversion of one nuclide into another. It can occur by the radioactive decay of a nucleus, or the reaction of a nucleus with another particle. The first manmade nucleus was produced in Ernest Rutherford’s laboratory in 1919 by a transmutation reaction, the bombardment of one type of nuclei with other nuclei or with neutrons. Rutherford bombarded nitrogen-14 atoms with high-speed α particles from a natural radioactive isotope of radium and observed protons being...
Microbial Bioremediation of Uranium
Microorganisms play a critical role in the transformation and immobilization of uranium in contaminated environments through four main pathways: bioreduction, biosorption, bioaccumulation, and biomineralization. These mechanisms reduce uranium’s toxicity and prevent its migration through groundwater systems, offering sustainable approaches for in situ bioremediation.Bioreduction of UraniumBioreduction is driven by anaerobic bacteria such as certain strains of Geobacter and Shewanella, which use...
Nuclear Stability
Protons and neutrons, collectively called nucleons, are packed together tightly in a nucleus. With a radius of about 10−15 meters, a nucleus is quite small compared to the radius of the entire atom, which is about 10−10 meters. Nuclei are extremely dense compared to bulk matter, averaging 1.8 × 1014 grams per cubic centimeter. If the earth’s density were equal to the average nuclear density, the earth’s radius would be only about 200 meters.

Nuclear Fission
Many heavier elements with smaller binding energies per nucleon can decompose into more stable elements that have intermediate mass numbers and larger binding energies per nucleon—that is, mass numbers and binding energies per nucleon that are closer to the “peak” of the binding energy graph near 56. Sometimes neutrons are also produced. This decomposition of a large nucleus into smaller pieces is called fission. The breaking is rather random with the formation of a large number of different...
Nuclear Fusion
The process of converting very light nuclei into heavier nuclei is also accompanied by the conversion of mass into large amounts of energy, a process called fusion. The principal source of energy in the sun is a net fusion reaction in which four hydrogen nuclei fuse and ultimately produce one helium nucleus and two positrons.
A helium nucleus has a mass that is 0.7% less than that of four hydrogen nuclei; this lost mass is converted into energy during the fusion. This reaction produces about...

Nuclear Power
Controlled nuclear fission reactions are used to generate electricity. Any nuclear reactor that produces power via the fission of uranium or plutonium by bombardment with neutrons has six components: nuclear fuel consisting of fissionable material, a nuclear moderator, a neutron source, control rods, reactor coolant, and a shield and containment system.
Nuclear Fuels
Nuclear fuel consists of a fissile isotope, such as uranium-235, which must be present in sufficient quantity to provide a...
