Description
In order to keep workers stay in main control room(MCR) and take emergency measures to relieve accident under accident conditions at nuclear power plants, main control room must be habitable. Because radiation level is important for habitability? the receiving radiation dose of workers must be within the limits of the regulations. This paper analyzes the dose characteristics of MCR under ejection rod accident as an example, explains the dose results of different ventilation modes, the dose contribution of different release paths and nuclide groups, and the dose trend with time. Sensitivity analysis of dose affected by the VES design parameters are performed based on the design characteristics of CAP1000. The result of this paper sustains the further dose analysis and habitability improvement of MCR. (authors)
