Synopsis:

The Applied Reactor Dosimetry course introduces the topic of radiation-induced material degradation and the methodology for its evaluation. The primary focus is on ensuring the safe operation of nuclear facilities, include not only reactors but also accelerators and other devices exposed to intense radiation.

After defining the fundamentals of radiation damage, the methods used to estimate the residual lifetime are introduced to students. Strong emphasis is placed on both code validation methods and the validation of the nuclear data used, as these are critical to the reliability of the computational results. Significant attention is given to the use of benchmarks in reactor and neutron physics. Students will also become familiar with the methodologies used in the benchmarking process, as well as standard instrumentation. The course concludes with an excursion to a facility involved in the Czech reactor surveillance program.
