Nuclear Engineering Research Groups (NERG)

Nuclear Engineering Research Groups (NERG)

These research groups and their associated research areas have been formulated in consultation with our key stakeholders, Emirates Nuclear Energy Corporation (ENEC) and the Federal Authority for Nuclear Regulation (FANR).  The links below outline the activities of each group, list their current resources and identify the Principal Investigators (PIs) and associated research faculty and staff.

  • Nuclear Instrumentation and Control Laboratory (NICL)

    The primary research subjects of Nuclear Instrumentation and Control Laboratory are the development and evaluation of nuclear I&C systems. Our research activities are related to the systems which receive thousands of plant field signals and process them to control the plants in normal and abnormal conditions. Since the whole systems include massive signals and electronic devices, and human operators, this research field involves not only nuclear engineering but also electrical engineering, computer science, industrial engineering, and cognitive science. Our research has a great potential to impact other research areas because we deal with such extreme conditions where ultra-high safety and reliability are requiredand massive information should be processed simultaneously. The representative research activities of our laboratory are the reliability estimation and development methodologies of digital systems including human performance, efficient evaluation of man-machine interface systems, and studies of cognitive engineering.
