About the job

Background

Several components in Swedish nuclear reactors are made of different types of stainless steel, which are exposed to mechanical vibrations, thermal changes, and high temperatures.

Furthermore, the increasing energy needs highlight the crucial role of Sweden's nuclear power plants' long term operation (LTO) program in ensuring stable, eco-friendly electricity production. The main goal of the LTO program is to extend the lifespan of nuclear reactors for many years. Additive manufacturing (AM) is seen as a key solution for efficiently replacing stainless steel parts once they reach the end of their lifespan.

Objectives

The aim of the MSc thesis project is to improve the understanding of the fatigue resistance of AM L stainless steel, considering different treatments and surface conditions. In addition, the project will investigate the anisotropic behavior by performing fatigue tests on specimens printed in various orientations. An existing numerical algorithm will be enhanced to simulate the fatigue life based on a comprehensive constitutive framework that includes anisotropic damage of the stainless steel.

The current thesis work involves various tasks:

  • Pre-study and literature review
  • Conducting fatigue tests at KTH to gather qualification data of AM specimens under different conditions
  • Analyzing anisotropic fatigue behavior of AM specimens printed in different directions
  • Investigating the test specimens and the AM material at KTH laboratories
  • Developing a return mapping model of anisotropic damage
  • Visiting Swedish nuclear power plants
