Gain basic and practical knowledge that is necessary for the understanding of the processes in a fission nuclear reactor.

Knowledge and understanding

Understanding of the physical processes that take place in a nuclear reactor during operation; ability to use the knowledge on the use of physical models and analytical methods to determine the key parameters of a nuclear reactor (multiplication factor, kinetics constants, fission density distribution).

Usage

Direct use of the knowledge gained on nuclear reactors, basis for gaining additional knowledge on reactor kinetics and fuel management in nuclear installations.

Reflection

The use of theoretical mathematical approach for solving specific physical problems in the planning and operation of a nuclear reactor.

Transferable skills – not limited to a single subject

Thorough knowledge of nuclear reactions of fission and capture, the use of analytical methods for the solution of elliptical differential equations, knowledge of numerical methods for the solution of second-order differential equations.

Lectures, exercises, seminars, consultations, practical exercises on the TRIGA reactor.

Exam from the exercises and at least one seminar are the precondition for the exam on the theory; exam on the theory.

Grades: 1-5 (negative), 6-10 (positive)(according to the statute of the UL).
