Methods and Tools for Core Design and Fuel Management in Light Water Reactors (LWR)

Course 018
 Title Methods and Tools for Core Design and Fuel Management in Light Water Reactors (LWR)
 Prerequisites Fundamentals of Nuclear Engineering
 Goal of the course Get familiar with basic methods and tools for core design and fuel management by combining theoretical background and hands-on training
 Content

This training course will start with the explanation of the principles for design of a LWR-core taking into account technical aspects, economics and safety.

Then, the theoretical basis of state-of-the-art numerical tools used for core design optimization and safety evaluations (reload safety) will be explained. This will cover advances thermal hydraulic methods implemented in sub-channel codes for fuel assembly and sub-channel level simulations that allow the quantification of thermal safety limits (MDNBR, MCPR).

Furthermore, the fundamentals of fuel management will be discussed together with some strategies for core loading pattern optimization. In this connection, LWR fuel cycle, economics aspects for core design and fuel management will be discussed.

Hands-on-training will includes practical exercises for LWR-cores devoted to:

  • Sub-channel analysis of PWR and BWR fuel assemblies and cores using the KIT-code SUBCHAFLOW
  • LWR-core design (including development of low leakage core designs, transition to equilibrium cycles, burnable poisons) using SCALE/POLARIS and SERPENT
  • Fuel assembly reshuffling using the core simulator PARCS

The course will be given in English
