Residual Life Assessment of Major Light Water Reactor Components - Overview

Life Cycle Comparison of Two Ro Concentrate Reduction Technologies

Desalination and water reuse technologies are critical for solving water problems. Unlocking water resources through the minimization of reverse osmosis (RO) concentrate volume offers sustainable opportunities to meet the challenge. A pellet softening lime intermediate concentrate chemical stabilization (ICCS) reactor and a conventional lime softening ICCS for the treatment of RO concentrate we...

Small modular reactors: A comprehensive overview of their economics and strategic aspects

A key challenge for engineers and scientists over the coming decades is to develop and deploy power plants with sufficient capacity and flexibility to meet the growing demand for energy (mainly electrical) whilst simultaneously reducing emissions (primarily greenhouse gases). With fusion-based power plants not currently being considered viable for large-scale deployment for at least 40 years, o...

Creep Life Assessment of Primary Reformer HP40-NB Modified Steel Tube of an Ammonia Plant

Assessment of creep damage and residual creep life of a cast HP 40 Nb Mod. Reformer tube was performed, wherein the experimental Larson–Miller diagram and area fraction of creep voids were adopted. The state of damage of the tube in service was metallographically analyzed by using light and electron microscopy. Samples from the serviced reformer furnace tube were cut and prepared for void exami...

Microstructural and microchemical mechanisms controlling intergranular stress corrosion cracking in light-water-reactor systems

This review paper examines mechanisms controlling IGSCC in selected LWR components. Emphasis is placed on identifying material microstructures and microchemistries which promote susceptibility to premature failure. Two important examples are evaluated in some detail: stainless steel pipe cracking and primary-side SCC of alloy 600 steam generator tubing. In each case, grain boundary segregation ...
