The unavailability of DG success is 4.75E−3 for 2/4 and 1.47E−3 for 1/4. Modeling includes sub systems like CB, SSWS, Fuel oil system & 220 V DC. DG-FR, DG-FR-CCF and DG maintenance is major contributors of DG unavailability. Uncertainty analysis has been carried out through Monte Carlo simulations. Sensitivity analysis identifies DG mechanical FR as most sensitive part.
