The Design and Fabrication of the Lead Corrosion Test Loop

Lead corrosion test loop named KPAL-II (KAERI Pb Alloy Loop II) has been designed and fabricated at the Korea Atomic Energy Research Institute (KAERI) and an initial operation was performed recently. The KPAL-II was designed to study the long-term corrosive effects of liquid lead on structural and fuel cladding materials at temperatures up to 600°C. The first run of KPAL-II took place on March 15^th, 2006 and three hundred hours of shakedown testing were performed with an isothermal condition at about 450°C. This paper summarizes the general design concept and the results of the shakedown testing of KPAL-II.
