ANS is committed to advancing, fostering, and promoting the development and application of nuclear sciences and technologies to benefit society.
Explore the many uses for nuclear science and its impact on energy, the environment, healthcare, food, and more.
Aerospace Nuclear Science & Technology
Organized to promote the advancement of knowledge in the use of nuclear science and technologies in the aerospace application. Specialized nuclear-based technologies and applications are needed to advance the state-of-the-art in aerospace design, engineering and operations to explore planetary bodies in our solar system and beyond, plus enhance the safety of air travel, especially high speed air travel. Areas of interest will include but are not limited to the creation of nuclear-based power and propulsion systems, multifunctional materials to protect humans and electronic components from atmospheric, space, and nuclear power system radiation, human factor strategies for the safety and reliable operation of nuclear power and propulsion plants by non-specialized personnel and more.

25th anniversary of failure (and a chance at opportunity)
Silver anniversaries are usually a cause for great celebration, but this one is a cause for regret and a renewed plea for action. January 31, 2023, marks the 25th anniversary of the Department of Energy’s failure under law and contract to start the removal of spent nuclear fuel (SNF) from the country’s 74 commercial nuclear power plant sites in 35 states for disposal per the Nuclear Waste Policy Act of 1982. I personally know the moral and legal responsibility associated with this failure, because in 1998, as the then responsible DOE official, I had to personally announce it. But much has changed since then. There are many new avenues to address these past problems like federal, state, and community partnerships that can be beneficial for all, if there is DOE leadership and congressional action for both disposal and storage.

In tokamaks, the problem of plasma current density and safety factor reconstruction, given the available measurements, can be strongly unstable with respect to the input data. Different constraints are used in practice to make the problem more stable. Traditionally, methods for equilibrium reconstruction search for one solution of the Grad-Shafranov equation with a set of constraints. However, the questions of the efficiency of a constraint in selecting a solution; the required accuracy of the measurements; the existence of very different solutions, which are compatible with the measurement errors; and the detailed assessment of the reconstruction confidence intervals are not addressed. This paper presents a numerical algorithm, based on the -net technique, which provides answers to all these questions. Examples of application of the method to the analysis of ITER- and JET-like plasmas are given.
