摘要

本文探究了γ辐射场下新型冷却剂硼-锂-氨的辐射分解行为，主要考察了不同硼-锂浓度、吸收剂量和吸收剂量率对辐解产物H,2,O,2,、NO,2,-,和NO,3,-,的浓度影响。实验结果表明：在常规的压水堆运行pH范围内（pH,300 ℃,=7.1~7.3），随着硼酸浓度增加，冷却剂体系的H,2,O,2,和NO,2,-,浓度没有明显变化，其中H,2,O,2,的浓度范围在9.28×10,-5,~1.07×10,-4, mol/L之间，NO,2,-,浓度范围为9×10,-6,~1.5×10,-5, mol/L；NO,3,-,浓度相较于前两个产物波动较大，为4×10,-5,~8×10,-5 ,mol/L。随着吸收剂量增加（1~30 kGy），硼-锂-氨体系中的H,2,O,2,和NO,2,-,的平衡浓度增加，分别为1.28×10,-4, mol/L和1.30×10,-5, mol/L，NO,3,-,的浓度未明显变化（4×10,-5,~6×10,-5, mol/L）。在本工作探究的吸收剂量率范围内（1.27~18.86 Gy/min），H,2,O,2,、NO,2,-,和NO,3,-,的浓度均未因吸收剂量率增加而受到显著影响。本工作为新型冷却剂硼-锂-氨体系的实际应用提供了有参考价值的基础数据。

Abstract

In this study, the γ-radiolysis,of boric acid-lithium hydroxide-ammonia coolant was investigated under different conditions, including boric acid concentration, absorbed dose, and absorbed dose rate. The concentrations of H,2,O,2, NO,2,-, and NO,3,- ,were determined using UV-visible spectroscopy and ion chromatography. With an increase in boric acid concentration, the concentrations of H,2,O,2, and NO,2,-, in the coolant system did not change significantly,within a pH range commonly used in pressurized water reactor operation. Specifically, the concentration of H,2,O,2, varied from 9.28×10,-5, to 1.07×10,-4, mol/L, while that of NO,2,-, changed from 0.9×10,-5, to 1.5×10,-5, mol/L. In contrast, the concentration of NO,3,-, fluctuated significantly, ranging from 4×10,-5, to 8×10,-5 ,mol/L. With an increase in the absorbed dose (1-30 kGy), the equilibrium concentration of H,2,O,2, and NO,2,-, in boric acid-lithium hydroxide-ammonia system increased to 1.28×10,-4, mol/L and 1.30×10,-5, mol/L, respectively. Meanwhile, the concentration of NO,3,-, did not change significantly (4×10,-5, to 6×10,-5, mol/L). The concentrations of the three radiolytic products were not significantly affected within the given absorbed dose rate range (1.27 to 18.86 Gy/min). Overall, this work provides valuable basic data for optimizing the new boric acid-lithium hydroxide-ammonia coolant system.
