Instructions

Reading digital theses in the closed network of the Aalto University Harald Herlin Learning Centre

In the closed network of Learning Centre you can read digital and digitized theses not available in the open network.

The Learning Centre contact details and opening hours: https://learningcentre.aalto.fi/en/harald-herlin-learning-centre/

You can read theses on the Learning Centre customer computers, which are available on all floors.

Logging on to the customer computers

  • Aalto University staff members log on to the customer computer using the Aalto username and password.
  • Other customers log on using a shared username and password.

Opening a thesis

  • On the desktop of the customer computers, you will find an icon titled:

    Aalto Thesis Database

  • Click on the icon to search for and open the thesis you are looking for from Aaltodoc database. You can find the thesis file by clicking the link on the OEV or OEVS field.

Reading the thesis

  • You can either print the thesis or read it on the customer computer screen.
  • You cannot save the thesis file on a flash drive or email it.

Abstract (eng): High Performance Light Water Reactor (HPLWR) is a new reactor concept that operates at supercritical pressure conditions.
VTT participates in the `HPLWR2' project, in which the technological feasibility and economical competitiveness of the concept are assessed, by calculating coupled neutronic and thermal-hydraulic analysis of the HPLWR plant.
An advanced core model TRAB-3D was chosen for neutronics calculation internally coupled to thermal-hydraulic system code SMABRE.
The work done for this thesis is part of VTT's contribution to the project.

To initiate the modelling of HPLWR at VTT, a thorough literature survey on the current state of the design was done in this thesis.
Based on the gathered data, input models of the HPLWR plant were made for TRAB-3D and SMABRE.
The capability of SMABRE to calculate supercritical pressure conditions were shown by calculating the Edwards-O'Brien blowdown test modified to supercritical pressures.
A functioning thermal-hydraulic steady-state for the HPLWR model was achieved with SMABRE.
However, due to complications with SMABRE, testing of the coupled model could not be started yet.

In addition to the coupled transient analysis, two-group constants for HPLWR fuel assembly were generated with PSG Monte Carlo neutron transport code developed at VTT.
The results were compared to parameterized cross sections received from Hungarian Academy of Sciences KFKI Atomic Energy Research Institute.
Reference values for infinite multiplication factor were calculated also with MCNP4C.
