Development of accuracy enhancement system for boron meters using multisensitive detector for reactor safety [PDF]

open access: yes, 2020
Boric acid is used as a coolant for pressurized-water reactors, and the degree of burnup is controlled by the concentration of boric acid. Therefore, accurate measurement of the concentration of boric acid is an important factor in reactor safety.

Corrosion behavior and characterization of plasma nitrided and borided AISI M2 steel [PDF]

open access: yesMaterials Research, 2014
This study investigates the corrosion behaviors of plasma nitrided (PN) and borided AISI M2 steels. The PN process was carried out in a dc-plasma system at a temperature of 923K for 6 h in a gas mixture of 80%N2-20%H2 under a constant pressure of 5 mbar.
