1. Mathematical Modelling of Structured Reactors with Emphasis on Catalytic Combustion Reactions
Sammanfattning : .... LÄS MER
2. Experimental analysis of thermal mixing at reactor conditions
Sammanfattning : High-cycle thermal fatigue arising from turbulent mixing of non-isothermal flows is a key issue associated with the life management and extension of nuclear power plants. The induced thermal loads and damage are not fully understood yet. LÄS MER
3. Experimental Study and Modelling of Spacer Grid Influence on Flow in Nuclear Fuel Assemblies
Sammanfattning : The work is focused on experimental study and modelling of spacer grid influence on single- and two-phase flow. In the experimental study a mock-up of a realistic fuel bundle with five spacer grids of thin plate spring construction was investigated. A special pressure measuring technique was used to measure pressure distribution inside the spacer. LÄS MER
4. Experimental and analytical study of thermal mixing at reactor conditions
Sammanfattning : High-cycle thermal fatigue due to turbulent mixing of streams at distinct temperatures is an interdisciplinary issue affecting safety and life extension of existing reactors together with the design of new reactors. It is challenging to model damage and thermal loads arising from the above mixing. LÄS MER
5. Mechanistic Modeling of Wall-Fluid Thermal Interactions for Innovative Nuclear Systems
Sammanfattning : Next generation nuclear power plants (GEN-IV) will be capable of not only producing energy in a reliable, safe and sustainable way, but they will also be capable of reducing the amount of nuclear waste, which has been accumulated over the lifetime of current-generation nuclear power plants, through transmutation. Due to the use of new and different coolants, existing computational tools need to be tested, further developed and improved in order to thermal-hydraulically design these power plants. LÄS MER
