Content
Department of Nuclear reactors offers Internship and Training in fields related to nuclear reactors, detection, proliferation, nuclear materials, nuclear safety, nuclear security and others. Hands on Internship program is tailored to participant background and needs. Every year, approximately 3 to 5 nuclear engineering internships are hosted by the Department. Internship length vary from few weeks up to one year. Interns have usually background in nuclear, however interns for safeguards are often with non-engineering background, so engineering background is not required.

| Application of Neural Networks for the Multiplication Factor Estimation of the VR-1 Reactor | Development and validation of neural network models to estimate the reactor's multiplication factor (k-eff) based on experimental and precalculated data. Applicants are expected to have prior experience with programming neural networks. Duration of the internship: | 05-09/2025 (can be shorter, but min. 3 months). | Ondřej Huml (This email address is being protected from spambots. You need JavaScript enabled to view it.) | open |
| Macroscopic Cross-Section Preparation and History Effect Evaluation for the APR1000 Core Model | This project focuses on the development of a full-core neutronic and thermal-hydraulics coupled calculation model for the APR1000 reactor. The Serpent2 neutronic calculation code will be used for the preparation of macroscopic cross-sections and the analysis of history effects during nuclear fuel burnup. The resulting model will be valuable for both educational purposes and optimization efforts. Models of the square fuel assembly and core geometry are particularly important in the context of the construction of new nuclear power plants in the Czech Republic. | 05-08/2025 (minimum 3 months, with the possibility of extension) | Pavel Suk (This email address is being protected from spambots.

| Core Simulator Startup Sequences Analysis | This project involves the development of methodologies for the physical and engineering startup processes of the Korean APR1000 power plant. The Czech Technical University in Prague has a unique opportunity to operate a real power plant core simulator, CoSi, which was obtained through international cooperation with Korean partners. This APR1000 core simulator plays a key role in the education of future nuclear reactor physicists and power plant staff. Students will develop methodologies for reactivity measurement, control rod calibration, and other measurements important for nuclear power plant operation. Part of the project will focus on simulating these methodologies on the core simulator and analyzing their benefits. | 05-08/2025 (minimum 3 months, with the possibility of extension) | Pavel Suk (This email address is being protected from spambots.

| Characterization of the semi-conductor HPGe detector | The intern should develop the approximate computation model of the HPGe detector and validate it by experiments with ethalon sources. Previous knowledge of the gamma spectrometry and programming/scripting skills are welcome. Duration of the internship: | 05-09/2025 (can be shorter, but min. 3 months). | Evžen Losa (This email address is being protected from spambots. You need JavaScript enabled to view it.) | open |
| Experiments on the VR-2 subcritical reactor: | Reactivity measurements on the subcritical reactor VR-2 and verification of experiments based on SERPENT code simulations | 04-07.2025 | Jan Rataj (This email address is being protected from spambots. You need JavaScript enabled to view it.) | open |
| SMR siting assesment | The SMR positioning has specific challenges and therefore it is necessary to conduct an analysis of external hazards and adjust the requirements. The intern should work on an analysis of sitting requirements related to external hazards. No previous experience needed. | 05-09/2025 (can be shorter, but min. 3 months). | Ondřej Novák This email address is being protected from spambots. You need JavaScript enabled to view it. | open |
| Safeguards by RMS | The Department of Nuclear Reactors operates a nuclear reactor and therefore has some storage of nuclear fuel. The intern should try to analyze data available from the radiation monitoring system (RMS) in order to track nuclear material around the facility and analyze the possibility to use it for safeguard activities. | 05-09/2025 (can be shorter, but min. 3 months). | Ondřej Novák This email address is being protected from spambots.

| Fuel performance evaluation of coated ATF cladding using FRACAS-CT code. | Fuel performance evaluation of coated ATF cladding using FRACAS-CT code—Accident-tolerant fuels are new types of nuclear fuels that provide enhanced safety and economics. Fuel performance codes model their behavior during normal operations and accidents. The FRACAS-CT code is an advanced multilayer code developed at KAERI. The internship aims to adopt the code, evaluate fuel behavior, and implement new models. | 4 months in spring/summer 2025 | Martin Ševeček (This email address is being protected from spambots.

| Post-CHF operation of LWRs - time at temperature limits. | Post-CHF operation of LWRs - time at temperature limits - Departure from Nucleate Boiling Ratio or CRP limits are currently used in LWRs to avoid a so-called billing crisis. However, this approach is too conservative and limits the operational limits of LWRs. New time at temperature limits can be used to replace the current safety basis. The internship will focus on the establishment of these limits. Both modeling and experiments will be included. | 4 months in spring/summer 2025 | Martin Ševeček (This email address is being protected from spambots.
