“…In recognition of the anticipated failure mode for a DBHE sodium-to-CO2 heat exchanger, an Argonne experiment program, SNAKE, was initiated in Fiscal Year 2010 (see Farmer et al, 2010;Gerardi et al 2011Gerardi et al , 2012aGerardi et al , 2012bGerardi et al , 2013a&b, 2014Gerardi et al , 2015a&b and 2016. The purpose of the SNAKE program was to investigate the reaction characteristics between sodium and CO2 under micro-leak conditions.…”
