Web14 apr. 2010 · As liquid lead-bismuth eutectic (LBE) cooled fast reactors, PEACER (Proliferation-resistant, Environment-friendly, Accident-tolerant, Continual, and Economical Reactor) was first developed in 1996 ... Lead-Bismuth Eutectic or LBE is a eutectic alloy of lead (44.5 at%) and bismuth (55.5 at%) used as a coolant in some nuclear reactors, and is a proposed coolant for the lead-cooled fast reactor, part of the Generation IV reactor initiative. It has a melting point of 123.5 °C/255.3 °F (pure lead melts at 327 °C/621 °F, pure bismuth at 271 °C/520 °F) and a boiling point of 1,670 °C/3,038 °F. Lead-bismuth alloys with between 30% and 75% bismuth all have melting points below 200 °C/…

WebVirtually transparent to neutrons: LBE is an ideal medium as spallation source inside the reactor where the linac’s proton beam is converted into neutrons required to sustain the … WebHistorically, LBE-cooled fast reactors were used to propel Soviet submarines since the 1960s and up to 1995. Valuable operational experience was gained, and the first evidences of corrosion fatigue of certain steels when in contact with LBE were reported (Bichuya et … Webty analyses of lead-alloy-cooled fast reactor systems. The vapor and liquid thermodynamic states of LBE were mod-eled up to and above the critical point based on a van-der-Waals type of equation. We assumed that LBE vapor is composed of monatomic lead and bismuth and diatomic bismuth components, and that liquid LBE is a non-ideal mix- hope 4 cg
