Phys 524 Basic Nuclear Physics for Power Reactors
Includes atomic nature of matter, mass defect and binding energy, modes of radioactive decay, radioactivity, neutron interactions, nuclear fission, energy release from fission and interaction of radiation with matter.
Includes the neutron life cycle, reactivity and reactivity coefficients, neutron poisons, Xenon, Samarium and other fission product poisons, control rods, and reactor start-up, operation and shutdown
Phys 526 Practical Projects on Nuclear Power
To enhance the student's understanding of the impact of nuclear technology on society and the environment, this module provides practical experience of the operation, shutdown, refueling and start up of a nuclear reactor, including visits to various nuclear establishments.
The first part consists of a practical project carried out at the SAFARI I nuclear research reactor at NECSA, involving the shutdown and start-up of the reactor. The second part involves the preparation of an Environmental Impact Assessment for a nuclear power reactor.
Phys 527 Introduction to Nuclear Engineering
This module gives an introduction to the nuclear field by the history of nuclear power, the major types of nuclear reactors, the nuclear fuel cycle, major nuclear reactor accidents, reactor core design, thermal hydraulic analysis, challenges faced in producing safe and economical nuclear power, aspects affecting core power density and how this impacts on reactor size, reactor control and shielding.
