The Monte Carlo (MCNPX) code has been used to the design a PGNAA facility for water chlorine content determination. The facility uses 241Am-9Be neutron source. Its configuration was optimized to yield maximum prompt gamma ray of chlorine in detectors, so minimize the relative statistical error. Then the calibration curve of measured count rate of 6110 keV gamma rays against the amount of Cl were obtained. The result permits PGNAA to be a valuable diagnostic tool for chlorine contamination of water.
