The Neutronics Section carries out research contributing to the design, operation, and safety of nuclear fission and fusion reactors and neutron spallation or other accelerator driven neutron sources. Of particular interest is ESS at Lund, Sweden and ITER at Cadarache, France.

Neutronics research at DTU contributes to the development of sustainable nuclear energy, to the design and operation of nuclear facilities and neutron sources, and to material science through neutron scattering experiments.

Reactor physics

A next generation of innovative nuclear fission reactors will meet safety, economic and environmental objectives for sustainable nuclear energy. Of particular interest is the Molten Salt Reactor and fuel cycle due to its high potential for improved safety and economics. We develop multi-physics numerical codes for simulating the neutronics – thermal hydraulics properties of the liquid fueled reactor, and we contribute to the design of essential safety components for the MSR.

Neutronics design

Neutronics analysis is indispensable for the design, construction and operation of nuclear reactors or accelerator-based neutron scattering facilities. These complex facilities, such as the European Spallation Source (ESS) require the continued development of modeling tools. We contribute to the design of instruments, moderators, neutron optics and diagnostics of ESS as well as the thermonuclear experimental fusion reactor, ITER.

Neutron scattering

In support of Danish utilization of neutron scattering facilities, in particular the ESS, we contribute to the development of codes for neutron transport and interactions, such as McStas, MCPL, and nCrystal. We apply the codes for simulating nuclear instruments and detectors and to optimize nuclear scattering experiments.
