Investigating the sedimentation of metallic fission particles in a molten salt nuclear reactor, an experimental and numerical study

Published Deadline Location
28 May 16 Jul Delft

Job description

The thorium based Molten Salt Reactor is a reactor that outperforms in safety and reduction of nuclear waste. It is possible to convert the nuclear waste from conventional reactors to short-lived nuclear waste, thereby reducing the lifetime of the waste from ten-thousands of years to 250 years. For these reasons a large number of initiatives has been started worldwide to develop such a reactor (e.g. Thorizon, Seaborg, Copenhage Atomics).

 

In a Molten Salt Reactor, solid fission particles tend to sediment on a surface, such as the reactor vessel and heat exchangers, deteriorating the properties of the structural materials in the reactor. In this unique project, the PhD student will study the sedimentation of these particles and its underlying mechanisms in high temperature molten salts. The approach is to develop an experimental facility, where parameters such as temperature, flow and materials can be changed and to extract data on the tendency of solid fission products to sediment under a range of conditions. The acquired data will then be used to validate own-developed numerical and physical models for sedimentation, so that a solid calculated estimate can be made in real cases and real situations. This PhD project is part of the recently granted EC project "ENDURANCE", which is a follow-up project of SAMOFAR and SAMOSAFER, both projects focused on thorium-based molten salt reactors.

 

The PhD student will be part of this international consortium and cooperate with the other members of the project, the technicians in our research group and with the principle investigator.

 

Start-date of the project is October 1, 2024.
