Abstract: In order to guarantee safe operation of marine floating nuclear power plants, human factor reliability of them is analyzed by using HCR model. Firstly, influence of external factors such as ocean microclimate, noise and hull motion on operating speed and accuracy was analyzed and quantified, and HCR model was modified. Then, with LOCA of marine floating nuclear power plants as an example, behaviors of people involved in the accident and their handling process were analyzed before values of calculation parameters were obtained according to accident scenarios. Finally, failure probability of operator's recognition of and response to abnormal LOCA signals was calculated. The results show that calculated results are in good agreement with actual situation, and the modified HCR model has greater operability.

Key words: marine floating nuclear power plant, human cognitive reliability (HCR), external factors, human reliability, loss of coolant accident (LOCA)
