2. 1. Development and Application of Reactor Noise Diagnostics

   Author : Joakim K.-H. Karlsson; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; BWR stability; noise decomposition; reactor noise; control rod vibrations; core barrel vibration; density wave oscillations; noise diagnostics; PWR noise; localisation; channel instability;

   Abstract : A number of problems in reactor noise diagnostics have been investigated within the framework of the present thesis. The six papers presented cover three relatively different areas, namely the use of analytical calculations of the neutron noise in simple reactor models, some aspects of boiling water reactor (BWR) stability and diagnostics of core barrel motion in pressurized water reactors (PWRs).

4. 2. Noise diagnostics of Stationary and Non-Stationary Reactor Processes

   Author : Carl Sunde; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; core-barrel vibrations; break-frequency method; wavelet; decay ratio; detector tube impacting; two-phase flow; spectral analysis; noise diagnostics;

   Abstract : This thesis concerns the application of noise diagnostics on different problems in the area of reactor physics involving both stationary and non-stationary core processes. Five different problems are treated, divided into three different parts. READ MORE
