Application of Hydrogen Service Fatigue Crack Growth Rate Models to a Simulated Remaining Life Assessment of Transmission Pipeline

The hydrogen economy envisions the use of gaseous hydrogen (herein referred to as hydrogen) as an energy carrier for the reduction of carbon emissions. Transportation of hydrogen from the upstream source (generation location) to the end-user will be necessary to maximize the carbon reduction potential switching from natural gas to pure hydrogen or hydrogen blended natural gas products. A proposed, economically viable option is to utilize the existing and extensive natural gas pipeline infrastructure in the United States.

Crack Growth Behaviour Of Cobalt Based Alloy In High Temperature Water

Product Number: ED22-17294-SG

Publication Date: 2022

$20.00

Co-based alloy (30Cr-4W-Bal.Co), such as Stellite TM grade 6 (UNS No. ERCOCr-A) valve seat, is used extensively in applications where superior resistance to wear corrosion are required. But there are only rare data about crack growth behavior of the alloy in the high temperature water. It is difficult to extract specimen from as welded Stellite-6, because of the valve sheet did not have enough volume. So, to evaluate the crack growth behavior and its temperature dependence, crack growth rate measurements were performed using forged Co-based alloy bar (Stellite TM grade 6B) (UNS No. R30016) in a simulated PWR primary water at temperature ranging from 250 to 320°C using half-inch size compact tension specimens (1/2TCT).

Cracking Behavior Of Decommissioned Baffle Plates In Light Water Reactor Environment

Product Number: ED22-17301-SG

Publication Date: 2022

Most of the core internal components of light water reactors (LWRs) are made of austenitic stainless steels (SSs). Exposed to fast neutron irradiation, reactor core internal components are vulnerable to irradiation-induced or irradiation-enhanced degradations. At LWR-relevant temperatures and irradiation doses, significant microstructural and microchemical changes can take place in SSs, leading to deteriorated mechanical and corrosion properties.

Effect Of Water Chemistry On Crack Growth Rates In Neutron Irradiated X-750 And XM-19

Product Number: ED22-17287-SG

Publication Date: 2022

As the current reactor fleet continues to age, with many reactors wanting to extend operational licenses beyond their initial 40 lifetime, it is becoming increasingly important to understand how structural materials in these reactor environments will degrade over time. A critical material degradation mode which can limit the lifetime of reactor components is irradiation assisted stress corrosion cracking (IASCC). As the name implies, a material must be subjected to both a corrosive environment as well as mechanical stresses while the original material microstructure has been affected by irradiation.

K / Size Effects on the Crack Growth Rate of Irradiated Stainless Steels of Boiling Water Reactors

Product Number: ED22-17304-SG

Author: Masato Koshiishi, Ryoji Obata, Shigeaki Tanaka

Publication Date: 2022

$20.00

Irradiation assisted stress corrosion cracking (IASCC) is a phenomenon caused by neutron irradiation of austenitic stainless steels (SSs). The crack growth rates (CGRs) of IASCC for boiling water reactor (BWR) components are needed for assessments to ensure component integrity. The CGR formula has been proposed as a function of the stress intensity factor (K).

Proposed Crack Growth Rate Disposition Curves For Stress Corrosion Cracking Of Alloy 82 In BWR Environments

Product Number: ED22-18350-SG

Publication Date: 2022

$20.00

A database of SCC growth rates in commercial austenitic stainless steels exposed to pressurized water reactor (PWR) primary water environments was developed and analyzed from international data in high temperature water, with an emphasis on deaerated or hydrogenated water while also including water containing oxygen. Crack growth rate (CGR) disposition equations were derived to reflect the effects of stress intensity factor (K), temperature, Vickers hardness (HV, to represent retained deformation), with enhancement factors for oxygen-containing, high corrosion potential conditions. The tolerance to chloride and sulfate impurities in PWR primary water was also evaluated.

The Hanford Nuclear Reservation contains radioactive and chemically hazardous wastes arising mostly from weapons production, beginning with World War II and continuing through the Cold War. The wastes are stored in 177 carbon steel underground storage tanks, of which 149 are single-shell tanks (SSTs) and the remaining are double-shell tanks (DSTs). The U.S. Department of Energy, Office of River Protection is responsible for retrieving the tank wastes, treating them in order to encapsulate them in glass logs, and then permanently closing the tanks and associated facilities.

SCC Initiation and Growth Rate Response of A-286 in B/Li and B/K Solutions 340°C

Product Number: ED22-17262-SG

Author: P.L. Andresen, P. Chou

Publication Date: 2022

$20.00

Stress corrosion cracking (SCC) initiation and growth rate testing was performed using Alloy A-286, a high-strength iron-base alloy, to evaluate for possible differences in response in boric acid solutions containing KOH vs. LiOH. PWRs are considering a switch from LiOH to KOH because of the uncertain future availability and high cost of Li. To achieve the same pH at temperature (pHT) in typical PWR primary water, the same molar concentration of Li and K is needed. The atomic weight of K is 39.1, which is 5.63 higher than the atomic weight of Li at 6.94, so 1 ppm Li yields the same pHT as 5.63 ppm K. The conductivity differs somewhat because of difference in the mobility of Li+ and K+.
