Design and development of enhanced criticality alarm system for nuclear applications

Nuclear Engineering and Technology, 2018
Criticality alarm systems (CASs) are mandatory in nuclear plants for prompt alarm in the event of any criticality incident. False criticality alarms are not desirable as they create a panic environment for radiation workers. The present article describes
