Dissolved oxygen control and monitoring implementation in the liquid lead–bismuth eutectic loop: HELIOS

A study of early corrosion behaviors of FeCrAl alloys in liquid lead–bismuth eutectic environments

“…The quantity of LBE in the alumina crucible was nominally 9 kg in weight. During the test, oxygen concentration in LBE was controlled over the range of 10 À6 -10 À5 wt.% by flowing H 2 /H 2 O gas with regulated composition and flow rates, and monitored by yttria-stabilized zirconia (YSZ) oxygen probe that was hermetically sealed using the electromagnetically swaged metal-ceramic joining method for long-term applications [12]. Oxygen-saturated bismuth (Bi/Bi 2 O 3 ) was used as a reference reaction couple that is placed inside YSZ.…”

Advanced passive design of small modular reactor cooled by heavy liquid metal natural circulation

“…The cover gas control system (CGCS) located above the reactor module controls the oxygen concentration in LBE for the corrosion control. In addition, this system removes toxic gases including Po gas from the primary containment space (Hwang et al, 2008a(Hwang et al, , 2008bNam et al, 2008). Fig.…”

Study of Digital Dissolved Oxygen Analytical Sensor of ppb-Level

“…The current only flows through the WE when the RE has already been added. The potential of the WE is stabilized by negative feedback of the RE, so the polarized voltage of the WE and the AE can easily be controlled when the diffusion current through the WE and the RE changes [23], [24]. We use 20% amount of silver-containing silver wire to make the RE.…”
