From August 29 to September 2, 2016, AdSTM conducted the subject workshop in Bucharest, Romania. The workshop was attended by members of the Romanian nuclear regulatory authority, CNCAN and personnel responsible for the operation of the two CANDU6 nuclear power plants operated in Romania. The workshop covered various aspects of the 2011 accident at Fukushima, the NRC response and follow-up activities to address the lessons learned from the accident. In addition, the workshop focused on the essential elements of a probabilistic risk assessment (PRA). The attendees learned about the basic PRA techniques, including how to develop event trees and fault trees, the utilization of component failure data, Levels 1, 2, and 3 PRA’s and seismic PRA’s. A combination of lectures and practical exercises were employed as training tools.
