Abstract

This notebook performs the calculations and the plotting of the figures in Chapters 3 - 4 in the book “Surveillance and Diagnostics of Next Generation Nuclear Reactors”. By running this notebook, all figures in Chapters 3 and 4 can be reproduced.
A more detailed description and user manual is available in the book.
Some of the plotting functions may require adjusting the plotting parameters (plot range, position of legends etc.).
The notebook can be used either with the input data corresponding to those used in the book, or with custom user input data, for investigating other systems, or the already investigated ones with different parameters (e.g. changing the core dimensions).

The github address to the data is
https://github.com/imre-chalmers-se/IET_book/tree/main/data/active

For importing the data into the variable “data” in a Mathematica notebook, the import command is
data = Import[“https : // raw . githubusercontent . com/imre - chalmers - se/IET_book/refs/heads/main/data/active/fileName.json”,“RawJSON”.]

Preamble


1. Select the reactor for the calculations and read the corresponding data file


2. Assign the input data to the variables and calculate the material bucklings


3. Simulate the radial dimension of the core (Green’s functions, variable strength absorber, vibrating fuel pin/absorber rod, localisation of both)


4. Plotting the results of the radial modelling


5 . Simulate the axial dimension of the core (propagating perturbations, propagation adjoints, transit time)


6. Plotting the results of the axial modelling

