Problems solved by technology

Although there are reports on nuclear power sacrificial materials at home and abroad, generally speaking, the currently prepared sacrificial materials have problems such as poor workability, low compressive strength, and poor corrosion resistance.
However, there is no report on the use of graphene or its derivatives to prepare sacrificial materials

Abstract

The invention discloses a novel siliceous nuclear power sacrificial material and a preparation method thereof. The novel sacrificial material is mainly prepared from 325-335 parts of PII.52.5-grade portland cement, 175-190 parts of pulverized fuel ash, 15-25 parts of silicon powder, 1,650-1,750 parts of quartz sand, 145-155 parts of water, 7-10 parts of water reducing agent, 1-1.5 parts of polypropylene fibers and 0.5-1.5 parts of sulfonated graphene. The preparation technology is simple, and a common forcing-type single-horizontal-shaft concrete mixer is adopted for preparing the nuclear power sacrificial material which is excellent in liquidity, strength and corrosion resistance. The prepared novel siliceous iron nuclear power sacrificial material has the advantages of good working performance, high strength, good corrosion resistance and the like, is mainly applied to a current third-generation nuclear power station reactor core catcher and has high engineering application value.

Description

Technical field [0001] The present invention relates to the field of nuclear material, and particularly relates to a novel nuclear siliceous material and preparation method of the sacrificial material. Background technique [0002] In the current third-generation nuclear power technology, in order to alleviate the serious nuclear accident, usually set core catcher under the third-generation nuclear reactor. Main core catcher for collecting, cooling and solidifying the molten core material. The sacrificial material is an important part of the core catcher nuclear power plant, the material plays a critical role in the process of cooling and solidification of the melt in the core. First, a sacrificial oxide core material may melt in a high radioactive material; secondly, the sacrificial material may reduce the temperature of the core melt; Finally, the sacrificial material may also reduce the internal pressure of the housing increased safety. Although there are reports of nuclear po...
