Modelling a Reactor Tutorial

Mini Core Heterogeneous Model

Building a Reactor Model with OSCAR-5, Part 1

This tutorial will focus on the model building capabilities of OSCAR-5. The process described in the Single Assembly tutorial will be discussed in more detail, at the hand of a hypothetical new reactor. The creation of a reactor model from scratch will be shadowed, thus models of all the different components will be created, after which they will be assembled into a complete core model that encompasses the reactor configuration and different possible reactor states. Special attention will be paid to the various ways in which different types of components can be modelled. Part 1 will focus on the creation of the detailed heterogeneous model, while Part 2 will cover the nodal path. At the end the model will be used to perform a control rod worth calculation.

Building a Reactor Model with OSCAR-5, Part 2

The focus of this tutorial is on the model building capabilities of OSCAR-5 and in particular, building the homogeneous nodal model. This tutorial picks up where Part 1 ends, therefore the heterogeneous mini core reactor model has been built. In this tutorial we will follow a theoretically consistent step-by-step approach to move from the detailed heterogeneous model to an energy condensed homogeneous nodal model. We will also quantify the errors introduced at each step in the homogenization procedure and define a final error estimate associated with the nodal model.
