Embodiment

[0061] Step 1: Sample preparation

[0062] The car chip-like sample was washed three times repeatedly with absolute ethanol, and after removing the oil on the surface, it was dried naturally for later use.

[0063] Step 2: Sample Dissolution

[0064] Accurately weigh m=0.5g sample and place it in a polytetrafluoroethylene beaker, add 3mL hydrofluoric acid solution, after the sample dissolves, add 0.5mL nitric acid solution, heat on the electric heating plate at 80°C until the solution is clear, then add 10mL saturated Transfer boric acid solution into a 50mL volumetric flask; add 3mL nitric acid solution and 2mL acetone into the volumetric flask, and shake well; then add 1mL silver nitrate solution, dilute with water to the mark, and shake well.

[0065] Step 3: Blank solution preparation

[0066] Add 3mL hydrofluoric acid solution and 0.5mL nitric acid solution to an empty polytetrafluoroethylene beaker, heat it on an electric heating plate at 80°C until the solution is cle...

Abstract

The invention relates to the technical field of chlorine content determination, and specifically discloses a method for determining the chlorine content in a uranium-zirconium alloy, comprising the following steps of: step 1, sample pretreatment; step 2, sample dissolution; step 3, blank solution preparation; step 4, standard curve drawing; step 5, sample determination; and step 6, results calculation. The method for determining the chlorine content in the uranium-zirconium alloy is high in measurement precision, and rapid and convenient to detect.

Description

technical field [0001] The invention belongs to the technical field of chlorine content measurement, in particular to a method for measuring chlorine content in uranium-zirconium alloys. Background technique [0002] Uranium-zirconium alloy is considered to be a promising one because of its good thermal conductivity, easy fission, high atomic density, low Zr thermal neutron cross-section, and the alloy has excellent corrosion resistance and dimensional stability in thermal cycles. Metal. Compared with oxide nuclear fuel, metal-type nuclear fuel is easier to reprocess spent fuel and has a higher uranium density, allowing the reactor to operate at a lower uranium abundance. However, there is no public report on the research results of the determination method of chlorine content in uranium-zirconium alloys. Contents of the invention [0003] The purpose of the present invention is to provide a method for determining the chlorine content in the uranium-zirconium alloy, so a...
