MSc Nuclear Science and Technology

The unit is based at the VR-1 reactor facility of the Czech Technical University in Prague. The reactor is a zero-power research nuclear reactor which is specifically used for training and research. There is no such facility in the UK that allows access for university students. The unit consolidates the theoretical understanding received from the core course units N01 (Reactor Physics, Criticality & Design) and N03 (Radiation & Radiological Protection) by hands-on practical experience on a reactor. The reactor neutronics and dynamics are demonstrated through experimental measurements of neutron fluxes, control rod calibrations, delayed neutron detection, reactivity measurements and reactor feedbacks. An understanding and appreciation of the instrumentation and controls of a reactor are gained during the experiments and through hands-on operating experience at the reactor control panel. The analysis, interpretation, presentation and review of the experimental data obtained in the practical exercises are important elements of the unit. Safety aspects of reactor operation and fuel handling and inspection are emphasised.

The unit aims to:
1. Consolidate the theoretical understanding of the fundamental aspects of reactor physics and dynamics by measurements and hands-on experience.
2. Provide understanding of fundamental reactor parameters and their effect on a reactor operation.
3. Demonstrate measurement methods for various reactor phenomena: neutron flux, delayed neutrons, absorption rod calibration and rod worth, reactor feedbacks, etc.
4. Emphasise safety aspects of reactor operation and give practical experience in radiation detectors and surveying levels of radiation for a reactor at full power.
5. Understand reactor instrumentation and control through hands-on reactor operation.

ILO 1  -  Evaluate important safety parameters of a reactor: reactor feedback and effects of control rods and verify outcomes through measurement.
ILO 2  -  Analyse and interpret data from reactor physics and dynamics measurements, leading to an assessment of the reactor condition.
ILO 3  -  Assess different methods for neutron detection and apply proper correction factors.
ILO 4  -  Apply delayed neutrons outside of a reactor core.
ILO 5  -  Design a preliminary system for a safe reactor operation.
ILO 6  -  Perform a safe approach to critical state for an unknown fissile system.

Students conduct measurements at the VR-1 reactor hall in a close proximity of VR-1 core vessel. Such arrangement provides an opportunity for a clear visualisation of all tasks within an experiment. Theoretical background knowledge and a measurement description is presented to students via a short presentation prior to every experiment. There are several breakpoints during presentation and experiment, where students are prompt to provide their ideas, expectation, and they are involved in ongoing analyses under a guidance of a lecturer. A paper copy of all presented materials is provided to the students. The learning process includes a large element of practical work in the reactor hall and data analysis. The in-unit activities will include the development of intellectual and practical skills through group presentations and discussions. Several methods of knowledge fixation are utilized during the course.
