Chemical compatibility study between ceramic breeder and EUROFER97 steel for HCPB-DEMO blanket

Study on the chemical compatibility between Li2TiO3 ceramic pebbles and diverse advanced structural materials

“…To calculate the oxygen diffusivity of the corrosion layer, the effective oxygen diffusivity can be estimated by measuring the oxide layer thickness. The effective diffusion coefficient of oxygen is given as follows 34 : $$$$\begin{equation}{\mathop{\rm D}\nolimits} = {d^2}/t{\rm{ }},\end{equation}$$$$where d is the thickness of the oxide layer, and t is the preservation time. It is estimated that the oxygen diffusion coefficient was 1.02*10 −14 cm 2 /s at 700 °C for 300 h. Moreover, Keisuke Mukai, et al reported that the effective diffusion coefficients of oxygen into EUROFER steel for 12 weeks were in the range from 3.5 × 10 −14 to 2.5 × 10 −12 cm 2 /s.…”

Strengthening mechanisms of reduced activation ferritic/martensitic steels: A review

“…Obviously, DBTT increases significantly with increasing grain size. Hence, a small grain size (i.e., 10-20 µm) is generally expected for RAFM steels [11][12][13][14][15][16].…”

“…The tensile properties of the material are comparable to those of commercial 9Cr-1MoVNb heat-resistant steels. Since then, many countries have developed different types of RAFM steels, such as the F82H [11] and JLF series steels [12] in Japan, the EUROFER97 steel [13] in Europe, the China low activation martensitic (CLAM) steel [14] in China [12][13], the INRAFM steel in India [15], and the ARAA steel in South Korea [16]. So far, RAFM steels have achieved industrial production.…”

Fluence of Phase Formation Processes in Lithium Zirconateceramics on Strengthand Thermal Properties

“…The interest in these studies is due to the great demand for tritium, which is one of the alternative energy sources, the accumulation of which is required to maintain the efficiency of thermonuclear fusion and the operation of thermonuclear reactors, including TOKAMAK or ITER [1][2][3]. As is known, traditional methods for producing tritium today cannot meet the demand for it, which requires additional research in ways to obtain it [4,5]. One such way is to reproduce the classical nuclear reaction of the 6 Li + n → He + T type, which makes it possible to obtain tritium from lithium, with its subsequent accumulation to support thermonuclear fusion.…”
