摘要

钍基熔盐堆是第四代核能系统的候选堆型之一，熔盐由于优异的传热性能与中子特性，被作为冷却剂和燃料盐载体在堆内运行，其微观结构对其物理化学性质有重大影响，因此，研究熔盐结构对熔盐制备净化、腐蚀控制以及熔盐堆的设计、建造和安全运行都有重要的指导作用。红外吸收光谱（Infrared Absorption Spectroscopy

IR）是研究熔盐结构的有力工具之一，但标准仪器无法实现高温（500℃）熔盐的测量。本研究在解决了样品加热、环境气氛控制以及腐蚀等难题后，研制了一套适用于高温氟化熔盐实验的高温原位红外吸收光谱装置。该装置中，加热炉为左右两开式，可以直接放进标准红外光谱仪样品仓内；样品池为组装式，主体是能够耐氟化熔盐腐蚀的镍基哈氏合金，窗片为单晶SiC或金刚石；样品池整体呈倒“T”型，上端密封盖带有进气口和出气口，可实现抽真空或通惰性气体的操作。该装置可以实现25-600℃温度范围测量，波段范围覆盖近红外和中红外（14700-400 cm

-1

）。通过使用常温水和高温亚硝酸钠的红外光谱实验对该装置的可靠性进行了验证。利用该装置，我们成功地获得了高温氟锂铍（FLiBe）熔盐的红外吸收光谱。

Abstract

Background

Molten fluoride salts which havegood heat transfer and neutron characteristic

were used as the primary and secondary coolants in the loops of thorium molten salt reactor (TMSR) that is a candidate of the generation IV reactor. Structure of molten salt plays an important role in the design

construction and safe operation of molten salt reactor. Infrared absorption spectroscopy (IR)is one of the powerful tools to study the structure of molten salt. However

the commercial standard instrument cannot realize high temperature measurement.

Purpose

This study aims to obtain the infrared absorption spectra of molten fluoride salt at the temperature upto 600 ℃ by developing an instrument constructed from commercially available components.

Methods

The main component of instrument is a Fourier transformation infrared (FTIR) spectrometer with wavenumber range of 14700-400 cm

-1

.Adetachable bottom board in sample compartment was built to allow a furnace to be put in it. The furnace was designed to be two-half pattern for the cuvette to be placed into and out of freely. It can be operated from room temperature to about 600℃. The cuvette

the most important component in the instrument

is made by Hastelloy C/N as the main body with a reverse'T'contour and diamond or crystalline SiC as the window plates. An optical translation stage was installed under the furnace to connect the furnace with the bottom board

which can make sure that the focus of light beam is overlapped with the center of cuvette.

Results

Performances of the instrument are demonstrated and verified with spectral studies of water at room temperature and molten salt nitrite at high temperature.

Conclusion

Using this instrument

the spectra of the molten fluoride salt (FLiBe)have been obtained.
