Abstract
In this paper, based on the X nuclear power nuclear reactor, the mixture ratio of the nuclear base plate concrete was designed. And the mechanical property test, adiabatic temperature rise test, concrete shrinkage test and durability test were performed. Basic mechanical property and the thermal performance of the nuclear base plate concrete were investigated. The results show as follows: The compressive strength of 28 days was 38.6 MPa. The derived relationship between specific heat (c) and temperatures (θ) was: c =0.0003322θ2- 0.246358θ+1.4571. The derived relationship between adiabatic temperature-rise and age was: Θn=45.45-45.75/ (1+0.00186n) (100/9). The chloride ions migration coefficient was 5.5×10-12m2/s less than 7×10- 12m2/s. All in all, the mixture ratio of the concrete is suitable for pouring the nuclear base plate of Hainan nuclear power plant nuclear reactor.
