Reactor Experiments -- Reactor Lab #3
Measuring Integral Blade Worth Curves within the UMLRR

The purpose of this experiment is to become familiar with various techniques for measuring blade worth curves within the UMLRR -- with focus on the Inverse Kinetics Method. In addition, an effort is made to validate the simple feedback-free point kinetics model that has been used to illustrate the various reactor operations scenarios addressed so far this semester, and also to formally benchmark the (recently-implemented) Inverse Kinetics capability at UMass-Lowell. This page contains links to the many files directly associated with Reactor Lab #3.

Upon completion of this experiment, the student should have a better understanding of various methods for measuring integral worth curves for a real reactor, and have more confidence in our ability to predict the approximate feedback-free behavior of a reactor via numerical solution of the point kinetics equations.
