Nuclear reactors inherently operate under extreme environments, and hence the materials and alloys utilized for their design are required to withstand unique conditions. Not only do these materials need to stand up to corrosion at high temperatures, but also in certain components must they resist microstructural and physical property changes due to radiation. Two of the major effects of radiation on reactor alloys and radiation-induced segregation (RIS) and precipitation, which have been observed in reactor pressure vessel (RPV) steels, ferritic-martensitic steels, nickel base alloys, and austenitic stainless steels.

Expanded Service Temperature Limits of Polymer Liners in Water Injection Pipelines

Product Number: 51319-12796-SG

Publication Date: 2019

Polymer liners especially polyethylene liners are commonly used as internal liners in water injection service. Historical seawater/produced water applications have a typical design temperature of 60°C or less and are usually operated at 30 – 40°C. Handling of oilfield water in the operating temperature range of 60°C to 90°C becomes a challenge. Very limited such applications have been reported and details of specific operational conditions are not known to validate safe and reliable performance at high temperatures.This paper explores the current state of the art for the increased temperature limits of high density polyethylene liners and identifies the most credible failure modes to be mitigated. A testing campaign was conducted on commercial grade high density polyethylene to de-risk the application of the liners to operating temperatures up to 80°C. A series of small scale testing were performed to understand the material properties under different conditions (temperature oil saturation oil/water concentration etc.). Performance properties of typical high density polyethylene was benchmarked against a proposed raised temperature polyethylene grade. The material properties were used as an input to a finite element analysis tool to evaluate the strains experienced by the liner at different locations such as a weld bead flange connection vent location. The testing and analysis provides increased confidence to expand the operational envelope of polyethylene liners to higher temperatures in produced water service. A condition monitoring plan has been developed to record the liner condition during operation.

Expanding Industry Access to Molecular Microbiological Methods: Development of an Off-the-Shelf Laboratory Workflow for qPCR and NGS Analysis

Product Number: 51319-13033-SG

Author: Neil Sharma

Publication Date: 2019

$20.00

Multiple families of microorganisms have been implicated in Microbiologically Influenced Corrosion (MIC) within the oil and gas industry as well as in other fields resulting in billions of dollars in damage annually. The ability to detect these organisms in a timely and accurate manner can allow for the implementation of appropriate treatment regimens that mitigate costs and minimize downtime.Molecular Microbiological Methods (MMMs) such as quantitative polymerase chain reaction (qPCR) and next-generation sequencing (NGS) can provide unparalleled insight into microbial communities for diagnosing and managing MIC. However the routine application of MMMs by industry is still limited today due to high testing costs and access to only a relatively small number of commercial or internal company laboratories with MMM testing capabilities.Our recent work has focused on building a complete off-the-shelf laboratory workflow for conducting qPCR and NGS-based 16S rRNA metagenomic analysis. This workflow includes: (1) easy-to-use kits for sample collection field sample preservation and nucleic acid extraction (2) a pre-optimized panel of qPCR assays targeting important MIC-related microorganisms such as Sulfate-Reducing Prokaryotes (SRPs) and (3) access to a secure online portal for automated processing and analysis of NGS data. The availability of this workflow will allow virtually any testing laboratory with moderately skilled personnel to quickly and confidently begin conducting MMM-based analyses. We report results encompassing the development and initial validation of this workflow using samples collected from oil and gas and wastewater facilities. This new workflow will significantly reduce testing costs help to standardize testing across laboratories and provide significantly greater industry access to these powerful analysis technologies.

Expanding SCC Safe Use Limit of Alloy 718 for Sour HTHP Downhole Applications

Product Number: 51324-20928-SG

Nickel alloy UNS N07718 (Alloy 718) is extensively used in the oil and gas industry. However, it is limited by NACE MR0175/ISO15156 which only permits use at a maximum of 200 psi (1.38 MPa) H2S partial pressure at 400°F (204°C). To expand the Stress Corrosion Cracking (SCC) safe use limit of Alloy 718, NACE TM0198 Slow Strain Rate (SSR) testing was performed first to identify an upper H2S limit (i.e., 650 psi [4.48 MPa]). NACE TM0177 C-ring testing subsequently qualified Alloy 718 at this high limit in modified NACE Level VII conditions, and also under 910 psi (6.27 MPa) H2S partial pressure in a simulated field environment (total 15 ksi [103 MPa]) based on equivalent dissolved H2S concentration. This is the highest service H2S limit reported for Alloy 718 and also evidence that validates the effectiveness of dissolved H2S concentration as new sour severity metric for Ni alloy SCC qualification.

Experimental Characterization of Grain Boundary Fracture Properties in a FeCr12Ni26Si3 Austenitic Stainless Steel Oxidized in PWR Environment

Product Number: ED22-17126-SG

Publication Date: 2022

$20.00

Austenitic stainless steels are used for the core internal structures (bolts, baffles, formers) in Pressurized Water Reactors (PWR). During operational service, baffle to former bolts have been observed to undergo Irradiation-Assisted Stress Corrosion Cracking (IASCC), which is characterized by intergranular cracking. IASCC results from the material corrosion susceptibility, the microstructural changes induced by irradiation, the corrosive media and the mechanical loading. Numerous studies have been conducted to evaluate the complex interplay between the different factors, mostly focusing on InterGranular Stress Corrosion Cracking (IGSCC) of pre-irradiated samples in PWR environment. In particular, the oxidation behavior of grain boundaries and the mechanical loading of grain boundaries have been assessed in details. Depending on the oxidation time and the GB nature, oxide penetration along GB has been observed. The intergranular oxide is composed of (Nix,Fe1-x)Cr2O4 spinels. However, all grain boundaries (GBs) do not have the same oxidation behavior, and it has been reported that high angle grain boundaries show higher oxidation susceptibility than special grain boundaries. Radiation induced segregation at grain boundaries might also lead to higher susceptibility to intergranular oxidation. Irradiation also modifies the deformation mechanisms in austenitic steels resulting in strain localization which is believed to be an important factor in IASCC initiation as it can lead to local increase of the stress due to dislocation pile-ups at GB.
