TL;DR: In this article, the development of low activation vanadium alloys and MHD insulator coatings for a Li-self cooled blanket is reviewed and compared with the comparison of thermal creep in vacuum and Li and its impact on mechanical properties.

TL;DR: In this article, a localized blanket concept is proposed by selecting molten-salt Flibe as a self-cooling tritium breeder from the main reason of safety: low tritium solubility, low reactivity with air and water, low pressure operation, and low MHD resistance which is compatible with the high magnetic field design in force-free helical reactor (FFHR).

TL;DR: An alternative method of orthogonal dual-pulse laser-induced breakdown spectrometry (LIBS) is proposed by employing flowing atmospheric helium gas without the use of a sample chamber to support the more-efficient operation and maintenance of heavy-water nuclear power plants.

TL;DR: In this paper, a TEA CO2 laser (350mJ 1.5mJ, 10.6mHz) was focused onto a metal sub-target under He as host gas at 1-atmospheric pressure with a small amount of impurity gas, such as water and ethanol vapors.

TL;DR: In this paper, the authors examined the thermal and mechanical properties of ZrB 2 by the measurement of specific heat, ultrasonic sound velocities, thermal diffusivity, and thermal expansion.
