A research report submitted to the Faculty of Engineering, University of the Witwatersrand, Johannesburg in partial fulfilment of the requirements for the degree of Master of Science in Engineering, Johannesburg, August 2017 / The objective of this research work is to investigate the use of a high reliability micro
grid to supply emergency electrical power to a nuclear facility following loss of offsite
power (LOOP) accident. Most of the nuclear facilities around the world utilize diesel
generators and battery banks as emergency power to back up the grid power supply. This
power supply configuration represents the concept of the micro-grid system. The research
work proposes reliability improvement of the emergency power supply by introducing
diverse energy sources and energy storage systems. The energy sources and storage
systems that were investigated include renewable energy sources, decay heat recovery
system and large scale energy storage systems. The investigation results presented
include information on the suitable energy sources and energy storage system,
establishment of the reliable architectural layout and evaluation of the micro-grid system
in terms of capacity adequacy and reliability. / XL2018
