Nuclear and Radiation Safety| Резюме: | An ECCS heat exchanger is modeled with the RELAP5 computer code to evaluate its performance in design-basis operation and emergency conditions depending on fouling of the heat exchange tubes. The potential range of thermal resistance coefficients is considered, various options for plugging of heat exchange tubes are assessed. Based on the results, variation in the heat exchanger efficiency, heat transfer coefficient and boundary parameters at which water temperature at heat exchanger outlet does not exceed 90ºC are evaluated. |
