The purpose of this paper is to model the operation of the Shutdown Cooling System SDCS for CANDU 6 nuclear power plants in case of LOCA accidents using Flowmaster calculation code by delimiting models and setting calculation assumptions input data for hydraulic analysis and input data for calculating thermal performance check for heat exchangers that are part of this system. 1 Introduction Abnormal operating conditions 3 for the SDCS were analyzed using Flowmaster 4 calculation code and a Power and energy industries have their unique challenges comparison of the results was made with data obtained but they all need to rely on the efficient running of their from a series of models developed in Pipenet. piping systems and therefore optimum design and From the results of the thermal-hydraulic analysis and continual effective maintenance are essential. The ability the comparison with data from the compilings performed to ensure accurate delivery of a product and raw materials with Pipenet it was found that in all operating conditions especially over long distances and significant elevation of the system in case of a LOCA type accident changes is vital to the overall operation and success of a performance requirements specified in the design documen- process plant. For such .
