Embodiment Construction

[0036] The technical solutions of the present invention will be further described in detail below through specific examples.

[0037] A method for cleaning nuclear fuel element grid strips according to the present invention is carried out according to the following steps:

[0038] Step 1. Immerse the cleaning tool loaded with strips into No. 1 cleaning tank for the first cleaning operation, and the No. 1 cleaning tank is equipped with 201 hydrocarbon cleaning agent;

[0039] The first cleaning operation includes: immersing the cleaning tool loaded with the strips into the No. 1 cleaning tank, driving the cleaning liquid to vibrate through the ultrasonic array, and shaking the cleaning tool with the strips up and down at the same time to generate relative motion with the cleaning solution Cleaning, after the first cleaning, the cleaning tool is lifted out of the cleaning solution and dripped;

[0040] Step 2. Immerse the cleaning tool loaded with strips into No. 2 cleaning tan...

Abstract

The invention relates to a manufacturing technique of nuclear fuel grillwork strips, in particular to a cleaning method of a nuclear fuel element grillwork stripe. A hydrocarbon cleaner serves as cleaning liquid, and the cleaning method comprises the cleaning links including primary cleaning operation, dewatering, secondary cleaning operation, third-time cleaning operation, steam bath cleaning operation and vacuum drying operation. The working efficiency of cleaning of the nuclear fuel element grillwork stripe is effectively improved, the working environment is improved, and the cleaning qualification rate of a stripe product is increased.

Description

technical field [0001] The invention belongs to the technical field of manufacturing nuclear fuel grid strips, and in particular relates to a cleaning method for nuclear fuel element grid strips. Background technique [0002] The grid strips for nuclear fuel elements are punched and formed by metal strips. After forming, metal shavings, abrasive grains, penetrant residues, lubricating grease, adhesives, ink, water and other foreign substances are easy to adhere to the strips. Cleaning is required. [0003] The existing method for cleaning the grid strips of nuclear fuel elements is mainly to set up a plurality of cleaning tanks. The cleaning tanks are equipped with cleaning liquid made by mixing deionized water and cleaning agent according to a certain ratio. The strip products enter each Ultrasonic cleaning is carried out in the cleaning tank under the atmospheric environment, and after all cleaning operations are completed, the strips are dried. The disadvantage of this ...
