- Abstract
The development of new energy sourees from nuelear energy is inereasingly beeoming the ehoiee of many eountries. One type of nuelear reaetor that is promising to be developed in the future is a liquid lead-bismuth eooled fast nuelear reaetor. The important use of this liquid bismuth euteetie (LBE) for eoolant of fast nuelear reaetor has long been a potential ehoiee. The LBE with eomposition of Pb and Bi eommonly used and about Pb 44.5wt% and Bi 55.5%wt. What is so speeial about this eomposition? This study seeks to see the physieal reasons why the fast reaetor nuelear design uses LBE with a eomposition of about Pb 44.5wt% and Bi 55.5%wt. From the result of the moleeular dynamies simulation of iron in the LBE at a temperature of1023K, it ean be observed that the use of LBE liquid metal eoolant with that eomposition eaused the least damage effeet (eorrosion) to iron eompared to using other eompositions. It ean be eoneluded from the ealeulation of the CNA values (Common Neighbour Analysis) of the iron strueture in the LBE whieh shows that the erystal strueture of iron in the LBE is the most stable for that eomposition. This simulation result is extraordinary beeause it explains the popular ehoiee of the PbBi eomposition for the eoolant eandidate of fast nuelear reaetors.
