Abstract

A kinetic precursor drift model has been implemented in the ORNL Modelica-based TRANSFORM library for first-order investigations into the behavior of fluid-fueled molten salt systems using a trace substances approach. The model captures the creation, decay, and transport or drift of precursor neutron groups in the reactor core and throughout the primary loop. The developed model compares favorably with an analytic method of a simplified problem and has also been successfully demonstrated to be able to couple overall system thermal-hydraulics, power generation, and reactivity feedback.
