AMPP Guide 21555-2024, Water Analysis for Corrosion Prediction - Sampling Analysis and Interpretation

Product Number: AMPP Guide 21555-2024

Publication Date: 2024

$109.00

This Guide focuses on those water chemistry parameters that are key for corrosion prediction. Additional parameters may be required for other materials and corrosion evaluations and decisions. This Guide does not provide a procedure for how, when, and where to take water samples or how to preserve samples.

AMPP TR21544-2022, Corrosion and Mitigation Techniques for Fire Protection Piping Systems

Product Number: AMPP TR21544-2022

Publication Date: 2022

$109.00

This report explains different types of corrosion phenomena and contributing factors of corrosion that can occur in fire protection systems (FPS), such as water corrosivity, MIC, trapped air (wet systems), residual water (dry systems), and pipe weld corrosion. The basis for selection of corrosion mitigation strategies for corrosion mitigation and management of FPS are also discussed.

Corrosion that results in pipe leakage or obstruction is the most significant issue for owners of water-based FPS or fire sprinkler systems, in terms of both cost and system reliability. Corrosion damage/products and mineral deposits can impair the effectiveness of sprinkler systems, leaving facilities vulnerable to uncontrolled fire loss even though they are equipped with fire protection systems. This report describes practices that have been successful in mitigating FPS corrosion.

DTT Vacuum Vessel Cooling Circuit: Borated Water Chemistry Assessment

Product Number: ED22-17307-SG

Author: Claudia Gasparrini, Luigi Di Pace, Nicholas Terranova, Rosaria Villari, Emanuela Martelli, Piergiorgio Sonato, Mauro Dalla Palma, Giuseppe G Scatigno

Publication Date: 2022

Water chemistry definition in nuclear fusion research experiments is under development. Many nuclear fusion experiments, such as the Italian Divertor Tokamak Test Facility (DTT)[1], the Korea Superconducting Tokamak Advanced Research (KSTAR) [2] and Japan Torus-60 Super Advanced (JT60SA) [3] reactors consider the use of enriched boric acid (up to 95% 10B) in water to shield the superconducting coils by neutrons generated from nuclear fusion reactions in the plasma chamber.

Understanding the Effect of Water Chemistry and Surface Grinding on the Stress Corrosion Cracking Initiation of Filler Metal 82

Product Number: ED22-17143-SG

SCC of Ni-base filler metal (FM) 82 has been reported in the nozzles and other components in Light Water Reactors (LWRs). The typical characteristics of stress corrosion cracking (SCC) of Ni-base alloys are a long incubation time followed by slow propagation, which can suddenly transition to fast propagation. Whilst there has been considerable effort expended to develop an SCC mechanism that can explain and predict SCC in Alloy 600, fewer studies have investigated SCC of FM 82. The Preferential Intergranular Oxidation (PIO) SCC mechanism of Alloy 600 proposed by Bertali et al. which is an evolution of the Selective Internal Oxidation SCC mechanism proposed by Scott and Le Calvar is considered one of the most representative primary water SCC mechanisms for Alloy 600.
