Abstract

This paper investigates the simulation study of signal processing of temperature fluctuations and their use in determining malfunctions in coolant fluid flow in a fuel subassembly, by the use of SCILAB software. SCILAB is free open source software with a GNU general public license (GPL) compatible license. Its main features includes a large number of mathematical functions, high level programming language, 2-D and 3-D graphics, advanced data structures and user defined data types. With respect to our purpose, this tool acts as an excellent setup for performing data analysis, signal processing and statistics. The variation of RMS fluctuation for different values of time with temperature increase has been investigated for aiding in program development for FPGA for use in real time monitoring.
