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.

Proton therapy in cancer treatment is an important application in nuclear science. As a key component of proton therapy, the patient positioning system (PPS) based on a robotic arm is used in cancer treatment. The PPS delivers the patient to the target position remotely for treatment with high accuracy. As a high safety and stability device in proton therapy, seismic load is one of the relevant accidental events that will affect the structural integrity of the PPS. In this study, a finite element model was built to investigate resistance of the PPS structure against seismic load. Two kinds of analysis methods (equivalent static analysis and response spectrum analysis) were carried out to calculate the displacement and stress fields to check the response of the PPS against the defined seismic load. The results indicated that all the stresses are lower than the permissible limits and the safety requirement.
