Division Spotlight
Operations & Power
Members focus on the dissemination of knowledge and information in the area of power reactors with particular application to the production of electric power and process heat. The division sponsors meetings on the coverage of applied nuclear science and engineering as related to power plants, non-power reactors, and other nuclear facilities. It encourages and assists with the dissemination of knowledge pertinent to the safe and efficient operation of nuclear facilities through professional staff development, information exchange, and supporting the generation of viable solutions to current issues.

ARPA-E announces $40 million to develop transmutation technologies for UNF
The Department of Energy’s Advanced Research Projects Agency–Energy (ARPA-E) announced $40 million in funding to develop cutting-edge technologies to enable the transmutation of used nuclear fuel into less-radioactive substances. According to ARPA-E, the new initiative addresses one of the agency’s core goals as outlined by Congress: to provide transformative solutions to improve the management, cleanup, and disposal of radioactive waste and spent nuclear fuel.

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.
