APPLICATION OF INTERVAL METHOD IN RELIABILITY ANALYSIS OF NUCLEAR PLANT OFF-SITE POWER SUPPLY
The loss of off-site power supply for nuclear power plants may lead to a core melt accident, with large potential risk. So the evaluation of loss of off-site power is important for the PSA (Probabilistic Safety Assessment). Uncertainty of the original parameters of electric grid components may be caused by the shortage of the statistical information, the approximation to model parameters or the statistic error. In order to deal with the uncertainty problem in electric grids, interval analysis method is introduced in this paper. The original reliability parameters that are changing in a certain range are treated with interval number. Thereby the uncertainty of the parameters can be calculated in the whole process of the probabilistic assessment. The proposed method has been tested on the reliability analysis evaluation of T power plant loss of off-site power. The results demonstrated the effectiveness and practical value of the interval analysis method.
