Ageing management in nuclear power plants
The proposed M.Sc. thesis will have four phases:  Analyze the requested ageing management requirements in the KTA 1403 using the principle of the “graded approach”.  Identify the main ageing mechanisms (e. g. radiation, vibration, temperature and pressure cycling, wetting, drying, …) for mechanical, electric, ancillary and building components.  Analyze the components at FRM II affected by these mechanisms and compare the existing ageing management program to the above-identified requirements.  Propose adaptations to the existing ageing management program. Your work will lead to a “basis report” on the ageing management program and initiate a change in the applicable internal FRM II procedures where required. Indispensable are discussion with external experts (e. g. TÜV SÜD) and the nuclear licensing authority (StMUV). You will be fully emerged into everyday life of the FRM II reactor operations department.

Calculation the neutron transport from the fuel element to the instrument and probably to the detector
The proposed M.Sc. thesis aims to bring the development of new instruments an important step forward. After getting into the required software and codes, the needs of the instruments regarding neutron flux and spectrum of the instruments have to be addressed. A particular focus will be laid on beamtubes and neutron guides for which new instruments and instrument upgrades are underway. Next, a script-based coupling routine for Serpent 2 and McStas is needed in order to transfer data between both codes. Finally, neutron spectra at each beam tube nozzle can be obtained using Serpent 2 and subsequently McStas will provide detailed information important to the instrument scientists. In summary the thesis can be divided into these three phases: 1. Thorough study of the needs of the instruments and getting into the codes 2. Set up suitable models for neutron transport in Serpent 2 and McStas 3. Calculate the neutron spectra at the beam tube nozzles and provide information to the instrument scientists

Neuronale Netze in Gammaspektren
Embedded in the conversion program at the FRM II, the working group “High Density Fuels/Reactor Physics” operates a unique uranium laboratory, which allows the handling of nuclear fuel. For the operation of such laboratory, the waste management plays an utmost important role and gamma spectroscopy is the preferred method to identify nuclides in order to dispose of accruing trash packages. The increasing capabilities of artificial intelligence and machine learning, offer the development of new methods that allow for an automated and fast nuclide identification. The proposed M.Sc. thesis aims to bring the evaluation of gamma spectra an important step forward by - Thorough check of the quality of the available training data - Set up of a suitable neural network to reliably identify nuclides in unassigned gamma spectra - Identification of influences of different gamma detectors on the nuclide assignment This position offers a stimulating scientific atmosphere within an international collaboration project with the leading experts in the field. The student will get access to high-performance computers to conduct the work. Day-to-day work is done under optimal supervision by scientists at FRM II and Hochschule München
