A model for operational risk of industrial facilities including ageing/test degradation effects and maintenance effectiveness by S.F. Quintão Ribeiro, J.J. Rivero

“…The paper presents a model for operational risk of industrial facilities with applications to nuclear power plants and uranium mining. The traditional models update the risk profile for specific operational conditions setting to one the failure probability of components which are known to be unavailable by failure or maintenance, while constant mean unavailability values from the original Probabilistic Safety Analysis (PSA) are kept for the rest. …”

Constructing a Method for an Evaluation Index System Based on Graph Distance Classification and Principal Component Analysis by Keyou Shi, Yong Liu, Zhijun Zhang, Qing Yu, Qiucai Zhang

“…Based on the importance of having an evaluation index system, a new method that combines PCA with graph distance classification is presented to make up the deficiencies of principal component analysis in the process of index screening, and this method is applied in the construction of an evaluation index system for the environmental quality of decommissioning uranium tailing. The seepage indexes were classified into six classes using graph distance classification, which selects the representative elements, including pH, ∑α, 210Pb, 210Po, F−, and NO3−. …”
