Abstract: Background:The measurement of tritium production rate for tritium breeding blanket is one key issue of fusion system. Purpose: A preparation method of liquid scintillation sample for tritium production rate measurement based on lithium carbonate pellet with aluminum foil coat was studied. Methods:According to the basic principle of liquid scintillation technique counting, it is necessary to bring lithium carbonate pellet with aluminum foil coat into the scintillation solution by chemistry process. Results & Conclusion:From the results, the liquid scintillation sample prepared by sodium hydroxide and hydrochloric acid can keep clear fluid without the liquid-liquid separation. To improve tritium counting efficiency and with a good compatibility, liquid scintillation sample for 20 mL should keep least 12-mL liquid scintillation and the temperature during the process of preparation and measurement must be 10-20℃ centigrade.

Key words: Aluminum foil, Li2CO3 pellet, Liquid scintillation sample, Tritium production rate measurement
