A reliability analysis is given for the emergency decay heat removal system of the Nuclear Ship "Mutsu" and the emergency sea water cooling system of the Nuclear Ship "Savannah", under ten typical nuclear ship accident conditions. Basic event probabilities under these accident conditions are estimated from literature survey.<BR>These systems of Mutsu and Savannah have almost the same reliability under the normal condition. The dispersive arrangement of a system is useful to prevent the reduction of the system reliability under the condition of an accident restricted in one room.<BR>As for the reliability of these two systems under various accident conditions, it is seen that the configuration and the environmental condition of a system are two main factors which determine the reliability of the system. Furthermore, it was found that, for the evaluation of the effectiveness of safety system of a nuclear ship, it is necessary to evaluate its reliability under various accident conditions.
