The Advanced High-Temperature Reactor: High-Temperature Fuel, Molten Salt Coolant, and Liquid-Metal-Reactor Plant

The Advanced High-Temperature Reactor is a new reactor concept that combines four existing technologies in a new way: (1) coated-particle graphite-matrix nuclear fuels (traditionally used for helium-cooled reactors), (2) Brayton power cycles, (3) passive safety systems and plant designs from liquid-metal-cooled fast reactors, and (4) low-pressure molten-salt coolants with boiling points far abo...

Scheduling High-Grade Steelmaking

The paper describes a scheduling system for a high-grade steel making plant. Because very specialized steel grades are produced the variety of the chemical analysis of the heats is very high and the lot sizes are small. One of the most constraining factors in the production is the infiltration of chemical elements between consecutive heats in the electric arc furnace. To find a schedule that vi...

A High Temperature Pulsed Corona Plasma Reactor

Non-thermal plasma reactors have recently been used for the treatment of gaseous pollutants. High energy electrons (several eV) are produced in the plasma while the gas remains near ambient temperatures. Pollutant molecules are decomposed by highly reactive chemical radicals created through electron collisions. The focus of this work is the treatment of pollutants from the exhaust of electric a...

Assessment of Cfd Codes Used in Nuclear Reactor Safety Simulations

The spectacular growth in computer hardware over the last quarter century and the accompanying advances in software development have resulted in the availability of reliable numerical tools for addressing safety issues in Nuclear Power Plants (NPPs). The first step forward was undertaken in the 1970s with the development of system codes using the two-fluid model approach [1], such as RELAP-5 [2...
