Thereafter the Fukushima setback, different resolutions are on-going to improved arrangements among agencies responsible for the safety of such facilities and jointly developed reasonable precautions that will mitigate future calamities. This paper accomplished to recognize and represent suggested business processes for the Malaysian Nuclear Power Generating Program (NPP) based on Alter's Work System Theory (WST). The work system method often considered as effective in describing the organizational system such as NPP. This method applied to frame and understands the user requirements within the business case of NPP. As a result, the business process was determined in respect of the emergency plan accordingly. This case study analytically processed by adopting qualitative grounding processes. These processes involved coding interpretation which providing structural analysis of the suggested system requirements in a form of business process modelling. This analysis comprising process fabrication using member checking technique and workflow driven approach, which then transformed into business process simulation in the future.
