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 deg. C. The first run of KPAL-II took place on March 15, 2006 and three hundred hours of shakedown testing were performed with an isothermal condition at about 450 deg. C. This paper summarizes the general design concept and the results of the shakedown testing of KPAL-II. (authors)
