Compatibility Issues of Heat Pipes for Radioactive Exposures
Abstract: AbstractSelection of alloys are refractory materials those withstand high temperature, radioactive embrittlement effects for long periods. Effects of high temperature and neutron embrittlement are subjects considered in this article. Effects of coolants, reactive gases like oxygen are facts of importance to select materials for reactor construction system. Selections of radioactive protecting alloys like sleeves are of importance to produce systems within margins of weight. Compatibilities have been decisive among material, …

Process Parameters Optimization for Ammonia Decomposition up to 99% in Coke Oven Plants
Abstract: Catalytic ammonia decomposition is carried out in the byproduct-plant of Coke Oven-3. This process is picking up due to its ability to decompose the ammonia recovered from coke oven gas. Because of the corrosive nature of ammonia, its removal is a necessity in coke oven byproduct plants. The process begins with the ammonia vapors coming from the ammonia distillation column. The vapors from the distillation unit flow into a refractory-lined …

Preliminary design assessment of heavy water purification columns through shortcut calculations including hydraulic and mass transfer characteristics
Abstract: Heavy water having deuterium content of 99.9% and more is used as the moderator and the coolant in pressurized heavy water nuclear reactors (PHWRs). This purity is maintained by vacuum distillation in packed columns. This work analyses the effect of packing type on preliminary column design based on certain user-defined specifications, with a focus on mass transfer and hydraulic characteristics of the column. Geometrical characteristics of commercial metallic packing materials …

A study on Bridging Chemical Transformation and Climate Feedbacks in the Earth System
Abstract: The atmosphere operates as a vast and complex chemical reactor, where minute-scale transformations exert profound influence on planetary-scale climate stability. This research investigates the multi-scale coupling between reactive tropospheric chemistry and large-scale climate feedbacks, challenging traditional modeling approaches that often divorce chemical kinetics from dynamic processes. By integrating high-resolution chemical transport models (CTMs) with comprehensive Earth System Models (ESMs), we map the flow of energy and matter from the molecular …
