Abstract
Even after the Fukushima accident, many countries remain interested in nuclear power around the globe. Some of these nuclear aspirant states do not have domestic human resources to perform all the activities required to run nuclear power plant. Accordingly, some of these countries will rely on foreign workforce if they own commercial nuclear power plant. One prime example of these countries is the United Arab Emirates (UAE). Due to the limited nature of domestic manpower, implementation of plant operation and physical protection, at least in part, is expected to be performed by expatriates, forming multicultural workforce. A question then arises: “How would the use of multicultural workforce affect the operational performance of a nuclear power plant?” This research work is an attempt to answer this question in the area of nuclear security. Accordingly, nuclear security risk assessment was performed in this work for a hypothetical multicultural workforce engaged in physical protection of a UAE nuclear power plant. Using the system dynamics approach, casual loop diagram of multi-culture effects on nuclear facility protection system was constructed to measure the vulnerability of the existing system for nuclear security. Cultural factors for UAE’s multicultural workforce case were evaluated using Additive weighting Technique and Hofstede’s Study for quantitative assessment. To examine the vulnerability of the physical protection system related to multi-culture aspects, 12 possible threats scenarios were assumed and a selected one was applied to the Vulnerability to Intrusion System Analysis (VISA) (as a modification of the Estimation of Adversary Sequence Interruption (EASI) Methodology) in this study. These methodologies were to compute how much system failure risks of physical protection are affected by multiculturalism.
