Bio

Dr. Pavan K. Shukla is an advisory engineer at Savannah River National Laboratory, South Carolina, Aiken, USA. Dr. Shukla focuses on pipeline and tank bottom corrosion control issues and corrosion of materials in nuclear systems and has worked in the corrosion industry for over 20 years. He has co-invented seven patents and authored over 90 journal and industry conference publications, two book chapters, and numerous technical reports. In 2015, he received a Research and Development 100 award for developing a cased pipeline corrosion model. Dr. Shukla has the AMPP Cathodic Protection Level 2 certification.

Dr. Shukla’s Wednesday afternoon presentation covers a 3-year DOE-EM program to develop a chemically and radiation resistant reference electrode for application in the Hanford tanks. Principally, improvements to the junction, casing materials and inner chamber backfill materials are being pursued.  The junction material at the interface between the waste and the inner chamber of the reference electrode was identified as a critical component in the failure of the reference electrodes. Replacement junction materials were tested under simulated waste conditions to evaluate permeation rate, conductivity and permselectivity. In conjunction with material selection, SRNL has investigated altering the overall design to extend the service life.
