Division Spotlight
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.

A stochastic model is described which enables quantitative assessment of the efficiency of safeguards operations in reprocessing or fabrication plants. The a priori assumption, or “zero-hypothesis” is that there has been no diversion of fissile material, the inspector’s task being to invalidate it. To detect diversion, the inspector can resort to three criteria: The first criterion sets an upper bound M for the total mass uncertainty. When the latter reaches M, the inspector will take a plant-wide inventory. The second criterion enables the inspector to decide whether or not an estimated mass balance is compatible with the agreed model, and the third criterion connects the mass uncertainty to the time it lasts; moreover, it settles the number of strategic points within the plant. As an application of the mathematical model developed, systematic cheating strategies are studied. Under the rules assumed, a diverter will achieve maximum total withdrawal at minimum probability of being caught by following a strategy of erratic withdrawal and occasional reinsertion. This renders it necessary for the inspector to assess an upper limit to the positive mass balance, a quite unexpected result.
