“…Possessing outstanding magnetic and mechanical properties by virtue of their intrinsic nature, magnetic stainless steels have been generated a lot of interest and evolved as very strong candidate materials in the fission power plants [2][3][4][5]. Ferritic and martensitic stainless steels are usually categorized as magnetic stainless steels since they exhibit a high magnetic permeability.…”

“…Ferritic and martensitic stainless steels are usually categorized as magnetic stainless steels since they exhibit a high magnetic permeability. Whereas, the austenitic stainless steels are often described as non-magnetic steels as their magnetic permeability is quite negligible [3][4][5]. Magnetic permeability values for the magnetic steels whose principal metallic phases at room temperature are ferrite and martensite are usually high (~14), whereas, the non-magnetic steels have a magnetic permeability of 1.0 or slightly more.…”

“…Magnetic permeability values for the magnetic steels whose principal metallic phases at room temperature are ferrite and martensite are usually high (~14), whereas, the non-magnetic steels have a magnetic permeability of 1.0 or slightly more. Austenitic stainless steels fall into this latter category because their austenitic structure at room temperature favors in low magnetic permeability [3][4][5]. 400 stainless steel series are generally martensitic and free from austenite, so they exhibit high permeability and attract a lot of attention in the applications of magnetic devices [2][3][4][5].…”

In this study, we report on an investigation of proton radiation resistance of 410 martensitic stainless steels under 3 MeV proton with the doses ranging from 1.0 × 10 15 to 1.0 × 10 17 p/cm 2 at the temperature 623 K. Vibrating sample magnetometer (VSM) and X-ray diffractometer (XRD) were used to study the variation of magnetic properties and structural damages by virtue of proton irradiation, respectively. VSM and XRD analysis revealed that the 410 martensitic stainless steels showed proton radiation resistance up to 10 17 p/cm 2 . Proton energy degradation and flux attenuations in 410 stainless steels as a function of penetration depth were calculated by using Stopping and Range of Ions in Matter (SRIM) code. It suggested that the 410 stainless steels have the radiation resistance up to 5.2 × 10 −3 dpa which corresponds to neutron irradiation of 3.5 × 10 18 n/cm 2 . These results could be used to predict the maintenance period of SUS410 stainless steels in fission power plants.

“…1,2) The SCWRs, which are operated at the pressure conditions higher than the thermodynamic critical point of water (374 C, 22.1 MPa), have advantages over the conventional water cooled reactors in terms of a thermal efficiency as well as in compactness and simplicity. The special characteristic of fluids near the thermodynamic critical point is that their thermodynamic properties vary rapidly with the temperature and pressure.…”

In the development of supercritical pressure water cooled reactors, it is important to understand the characteristics of a heat transfer near the thermodynamic critical point. An experimental study on the critical heat flux near the critical pressure has been performed with a 5 Â 5 square array heater rod bundle cooled by R-134a fluid (P c ¼ 4:059 MPa, T c ¼ 101 C). The critical power has been accurately measured up to the reduced pressure of 0.99 (4.03 MPa). The critical power decreases sharply at a pressure of about 3.8-3.9 MPa as the pressure approaches the critical pressure. For the low mass fluxes of 50 to 250 kg/m 2 , a sharp decrease in the critical power is not observed near the critical pressure. The CHF phenomenon near the critical pressure no longer leads to an inordinate increase in the heated wall temperature such as the case of DNB at normal pressure conditions. In the pressure region close to the critical pressure, there is a threshold pressure at which the CHF phenomenon disappears. When the pressure exceeds the threshold pressure, the wall temperature increases monotonously without a CHF occurrence according to the power level applied to the heater rods. The threshold pressure moves toward the lower pressure region gradually with an increasing mass flux.
