Division Spotlight
Decommissioning & Environmental Sciences
The mission of the Decommissioning and Environmental Sciences (DES) Division is to promote the development and use of those skills and technologies associated with the use of nuclear energy and the optimal management and stewardship of the environment, sustainable development, decommissioning, remediation, reutilization, and long-term surveillance and maintenance of nuclear-related installations, and sites. The target audience for this effort is the membership of the Division, the Society, and the public at large.

Kentucky legislature sends nuclear bills to governor
Kentucky’s Republican-majority legislature passed a bill this past week that could bring nuclear energy to the “coal-is-king” state as lawmakers broadly seek solutions to reduce carbon emissions. The bill went to Democratic Gov. Andrew Beshear on Monday for final approval.

An electromagnetic flowmeter (EMFM) has been used in the main cooling loop of the fast reactor, but the large-sized magnet structure of conventional EMFMs was not adopted. Therefore, it is necessary to develop a novel EMFM with small-sized magnets for the fast reactor. But the fear is that the decrease in the magnetic field and the end effect will make the EMFM’s performance worse, though there is no detailed information about the end effect due to such small-sized magnets. This paper describes the EMFM with small-sized magnets for coolant monitoring. By using three-dimensional steady-state electromagnetic analysis, we have studied numerically the end effect of an EMFM with saddle-shaped permanent magnets that are smaller in size than the pipe diameter. Consequently, it has been clarified that the performance of an EMFM can be improved by utilizing the effect of the downstream end of magnets and by combining the inclined electrodes and the effect of the circumferential ends of magnets.
