[세미나] Radiation-Slows Corrosion in Molten Salt, and Accelerates Corrosion in Liquid Lead

안녕하세요.
2월 1일 목요일 MIT 원자력공학과의 Michael Short 교수님의 세미나가 있을 예정입니다. 

일시: 2월 1일 목요일 9:30 - 11:30 

장소: 38동 422호

현재 진행하고 있는 연구와 더불어 MIT의 Capstone design 프로젝트 수업을 소개하는 세미나를 개최합니다.
아래 세미나 제목과 초록을 확인하시고, 학생들의 많은 참여를 부탁 드립니다. 

 

Abstract: We usually think of radiation damage as "bad news," always as something to be avoided or mitigated. However, we have discovered that radiation slows corrosion of NI-based alloys in molten fluoride salts, giving us some good news for molten salt reactors. I will show our world-unique irradiation/corrosion facility, where researchers can see how simultaneous irradiation and corrosion change rates and mechanisms of corrosion in molten salts and liquid metals. Then I will show how and why radiation slows corrosion in Ni-alloys in molten salts, and present ideas why we think it speeds corrosion in liquid lead. Mechanisms of diffusion-induced grain boundary migration and newly observed 'wormhole corrosion' are notable features in all cases, while radiation induced wettability helps to spread out localized corrosion into a more uniform, predictable form in all cases. These results give an early look into how materials will behave when reactors are on, and can help predict new failure modes or even new margins to take back in reactor design.

 

Abstract: I will present how MIT's Department of Nuclear Science and Engineering (NSE) runs its design courses very differently from those in most other nuclear departments. We focus on student-initiated ideas, scientific and public communication, open-ended iterative design, immediate real-world impact, AnthroEngineering, and user-needs finding at every step. The proof is in the results - in the past 8 years, our design courses have spun out MiCon Technology Inc., Commonwealth Fusion Systems, and a cross-school effort to completely decarbonize Ulaanbaatar, Mongolia with a molten salt heat storage system.

 

감사합니다.
