High-temperature plumbing and advanced reactors
The use of nuclear fission power and its role in impacting climate change is hotly debated. Fission advocates argue that short-term solutions would involve the rapid deployment of Gen III+ nuclear reactors, like Vogtle-3 and -4, while long-term climate change impact would rely on the creation and implementation of Gen IV reactors, “inherently safe” reactors that use passive laws of physics and chemistry rather than active controls such as valves and pumps to operate safely. While Gen IV reactors vary in many ways, one thing unites nearly all of them: the use of exotic, high-temperature coolants. These fluids, like molten salts and liquid metals, can enable reactor engineers to design much safer nuclear reactors—ultimately because the boiling point of each fluid is extremely high. Fluids that remain liquid over large temperature ranges can provide good heat transfer through many demanding conditions, all with minimal pressurization. Although the most apparent use for these fluids is advanced fission power, they have the potential to be applied to other power generation sources such as fusion, thermal storage, solar, or high-temperature process heat.1–3

If you are attending the 2021 Winter Meeting, we will require either proof of COVID-19 vaccination, or a negative COVID-19 test taken within 72 hours of arrival at the Washington Hilton Hotel.
ANS values the health and safety of all our members. We will continue to follow all CDC, State, City, and Hotel safety requirements in our efforts to provide you a safe environment as we gather again.
The server used by EventScan for uploading your vaccination information is the same type of server used by hospitals, surgical centers, and emergency clinics. Once uploaded, your vaccination information is stored on an encrypted HIPAA server during the information collection timeframe for laboratory purposes. The data is kept encrypted on the server until conclusion of the meeting, and all attendees receive notification of verification, by email through the secured system.
