摘要

氚增殖包层中产氚率的测量是聚变核能系统中需要研究的重要问题之一，本文开展了用于产氚率测量的Al箔封装碳酸锂探测片液闪样品制备化学处理方法的研究。结果表明，首先采用氢氧化钠溶液来溶解Al箔，然后再用盐酸溶解碳酸锂探测片的溶解方式，能制成透明度高且无分层的液闪样品。为了提高测氚计数效率和保证样品兼容性，对20 mL的标准液闪样品，闪烁液体积应至少取12 mL，同时还应将液闪样品保持在10-20℃范围进行储存和测量。

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.
