REACTIVITY MEASUREMENTS IN SUBCRITICAL NUCLEAR REACTORS BY MEANS OF SOURCE STEP TECHNIQUES

摘要

Two methods of measuring reactivates and a variety of evaluation procedures are described. The methods make use of the source step technique, and cover a wide range of negative reactivates from -0.1 $ to about -10 $.nOne of the methods, called the "amplitude method", gives fairly good precision, but involves corrections for systematic errors induced by harmonics.
