The section Physics of Nuclear Reactors (PNR) is one of the five sections of the department of Radiation, Radionuclides and Reactors. The department belongs to the faculty of Applied Sciences of Delft University of Technology. The section aims to improve the sustainability of nuclear energy by theoretical and experimental research in reactor physics. The research is divided in three main pillars: theoretical research focussing on particle transport methods, thermal hydraulics research focussing on two-phase flow phenomena and stability analysis, and research on generation-IV reactor systems including the thorium fuel cycle.

In the theoretical research, the section focuses at new variance-reduction techniques in static and time-dependent Monte-Carlo calculations, and at deterministic transport methods. This latter research recently led to the PHANTOM finite element code using spherical harmonics expansions, which can be used for all stationary and time-dependent problems. For the cross-section generation, highly qualified lattice codes are used like APOLLO2 (CEA), ERANOS2 (CEA), and the SCALE code system (ORNL). Furthermore, ad joint sensitivity methods are being developed for non-linearly coupled neutronics-thermal hydraulics problems.

From the experimental side, three large facilities are available, being CIRCUS-IV (low pressure BWR), GENESIS (high pressure BWR) and the new Super-Critical loop (SCWR/HPLWR). Besides, detailed experimental studies are performed on flow and heat transfer with the help of, among others, advanced PIV and LDA measurement techniques.

In the field of reactor systems, focus is on core design, nuclear safety, and fuel cycle analysis of the (Very) High Temperature Reactor, the Molten Salt Reactor, and various fast reactor systems including the Gas-cooled Fast Reactor and Accelerator Driven Systems. Ultimate goal is to recycle all actinides and with that to reduce the lifetime of nuclear waste and to enhance the utilization of uranium and thorium.
