Embodiment 1

[0025] Embodiment 1: the preparation of different formula boric acid crystallization removers

[0026] Prepare boric acid crystallization removers of different formulations according to the following table 1.

[0027] The formula of table 1 boric acid crystallization remover

[0028]

Embodiment 2

[0029] Embodiment 2: Boric acid crystallization remover removes boric acid crystallization test in light water reactor nuclear power plant

[0030] The boric acid crystallization remover of each formula in table 1 is used for the removal of the boric acid crystallization in the light water reactor nuclear power plant, and method is as follows:

[0031] (1) Pour the prepared boric acid crystal remover into the pressurized watering can, the volume should be less than two-thirds and greater than one-third of the volume of the watering can;

[0032] (2) Manually press the pressure device above the watering can to inflate the watering can. After the pressurization is completed, adjust the nozzle of the watering can to control the particle size of the sprayed solution to ensure that the sprayed boric acid crystal remover can form mist or foam. Can;

[0033] (3) Use the watering can to aim at the stained area with boric acid crystals and spray evenly, so that the mist or foam of the...

Abstract

The invention belongs to the technical field of industrial decontamination, and relates to a boric acid crystal removing agent and applications thereof, wherein the boric acid crystal removing agent comprises water, sodium hydroxide, glycerin and an anionic surfactant, and the applications comprise: applying the boric acid crystal removing agent in the removal of boric acid crystals in light waterreactor nuclear power plants. According to the present invention, the boric acid crystal removing agent can rapidly and efficiently dissolve boric acid crystals at a normal temperature, can be used in various complicated environments, and is especially suitable for the removal of boric acid crystals in light water reactor nuclear power plants.

Description

technical field [0001] The invention belongs to the technical field of industrial decontamination, and relates to a boric acid crystal remover and application thereof. Background technique [0002] With the vigorous development of my country's nuclear power industry, as of the end of 2016, my country had 36 nuclear power units in operation, and by 2020, it is expected that the number of nuclear power units in my country will reach more than 60. In terms of installed capacity, it will surpass France and become the world's largest nuclear power unit. The second largest nuclear power country, after the United States. At present, my country's nuclear power units are all light water reactors except for the two of Qinshan Third Nuclear Power Plant which are heavy water reactors. [0003] As a neutron absorber, boric acid plays the role of reactivity control and neutron shielding, and is widely used in the primary circuit system of light water reactor nuclear power plants. During ...
