Available in PDF, EPUB and Kindle. Book excerpt: Between 2007 and 2009, several different multi-probe corrosion monitoring systems were designed and installed in high-level nuclear waste tanks at the U.S. Department of Energy's Hanford Site in WaShington State. The probe systems are being monitored to ensure waste tanks operate in regions that minimize localized corrosion (i.e., pitting) and stress corrosion cracking. The corrosion monitoring systems have been installed in wastes with different chemistry types. An ongoing effort during the same time period has generated non-radioactive simulants that are tested in the laboratory to establish baseline corrosion monitoring system performance and characterize data to allow interpretation of readings from the multiple corrosion monitoring systems. Data collection from these monitoring systems has reached the point where the results allow comparison with the laboratory testing. This paper presents analytical results from the corrosion monitoring system development program.

Download or read book Corrosion Probe Innovative Technology Summary Report written by and published by . This book was released on 1999 with total page 18 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over 253 million liters of high-level waste (HLW) generated from plutonium production is stored in mild steel tanks at the Department of Energy (DOE) Hanford Site. Corrosion monitoring of double-shell storage tanks (DSTs) is currently performed at Hanford using a combination of process knowledge and tank waste sampling and analysis. Available technologies for corrosion monitoring have progressed to a point where it is feasible to monitor and control corrosion by on-line monitoring of the corrosion process and direct addition of corrosion inhibitors. The electrochemical noise (EN) technique deploys EN-based corrosion monitoring probes into storage tanks. This system is specifically designed to measure corrosion rates and detect changes in waste chemistry that trigger the onset of pitting and cracking. These on-line probes can determine whether additional corrosion inhibitor is required and, if so, provide information on an effective end point to the corrosion inhibitor addition procedure. This report describes the technology, its performance, its application, costs, regulatory and policy issues, and lessons learned.

Download or read book Process Test Plan for 4TH Generation Hanford Corrosion Monitoring System written by and published by . This book was released on 2000 with total page 9 pages. Available in PDF, EPUB and Kindle. Book excerpt: Instrumentation and cabinets for the 241-AN-107 and 241-AN-102 corrosion monitoring systems will be upgraded in FY 2000. The bulk of the field work involved in this task will involve placement of the corrosion monitoring data collection hardware closer to the risers that house the existing corrosion probes. This will be accomplished by placing a new climate controlled cabinet by the risers containing corrosion probes on these two tanks (one cabinet per tank). Once installed the systems will feed data back to a centralized corrosion monitoring station in the 241-AN-271 instrument building. The upgraded systems will be operated under the bounds of this Process Test Plan (PTP) for six principle reasons. These reasons were established prior to installing the original systems in 1997 (241-AN-107) and 1998 (241-AN-102). They are as follows: (1) Acquire corrosion data on the waste in 241-AN-107 and 241-AN-102. (2) Provide supporting data to the site's Integrity Assessment program. (3) Demonstrate that corrosion monitoring by evaluation of electrochemical noise data is possible in waste tank systems, particularly with regard to the detection of general corrosion and (if present) pitting and stress corrosion cracking. (4) Demonstrate the durability of the design of the corrosion monitoring equipment. (5) Extend tank life and reduce annual operations cost. (6) Provide basis to control corrosion in double shell tanks though the use of direct corrosion monitoring rather than waste sampling and analysis. The designs of the existing corrosion probes in 241-AN-107 and 241-AN-102 were reviewed and documented prior to the original installation activities in 1997 and 1998. Initial programmatic documentation for Hanford's corrosion monitoring program was also established prior to the original installation activities.

Download or read book Hanford Prototype Corrosion Probe Operational Experience written by and published by . This book was released on 1996 with total page 22 pages. Available in PDF, EPUB and Kindle. Book excerpt: High-level nuclear wastes at the Hanford Site are stored underground in carbon steel double-shell and single-shell tanks. The installation of a prototype corrosion monitoring system into double- shell tank 241-AZ-101 was completed in August, 1996. The system monitors fluctuations in corrosion current and potential (electrochemical noise) occurring on three electrode arrays immersed in the waste liquid and in the vapor space above the waste. The system also supports the use of Tafel and linear polarization resistance testing. By monitoring and analyzing the data from these techniques, changes; in the corrosive characteristics of the waste have been rapidly detected and correlated with operational changes in the tank.

Download or read book Data Analysis and Reduction in Hanford s Corrosion Monitoring Systems written by and published by . This book was released on 1999 with total page 18 pages. Available in PDF, EPUB and Kindle. Book excerpt: A project to improve the Hanford Site's corrosion monitoring strategy was started in 1995. The project is designed to integrate EN-based corrosion monitoring into the site's corrosion monitoring strategy. In order to monitor multiple tanks, a major focus of this project has been to automate the data collection and analysis process. Data collection and analysis from the early EN corrosion monitoring equipment (241-AZ-101 and 241-AN-107) was primarily performed manually by a trained operator skilled in the analysis of EN data. Thousands of raw data files were collected, manually sorted and stored. Further statistical analysis of these files was performed by manually stripping out data from thousands of raw data files and calculating statistics in a spreadsheet format. Plotting and other graphical display analyses were performed by manually exporting data from the data files or spreadsheet into another plotting or presentation software package. In 1999, an Amulet/PRP system was procured and employed on the 241-AN-102 corrosion monitoring system. A duplicate system was purchased for use on the upcoming 241-AN-105 system. A third system has been procured and will eventually be used to upgrade the 241-AN-107 system. The Amulet software has greatly improved the automation of waste tank EN data analysis. In contrast with previous systems, the Amulet operator no longer has to manually collect, sort, store, and analyze thousands of raw EN data files. Amulet writes all data to a single database. Statistical analysis, uniform corrosion rate, and other derived parameters are automatically calculated in Amulet from the raw data while the raw data are being collected. Other improvements in plotting and presentation make inspection of the data a much quicker and relatively easy task. These and other improvements have greatly improved the speed at which EN data can be analyzed in addition to improving the quality of the final interpretation. The increase in data automation offered by the Amulet software is necessary if multiple tanks are to instrumented and analyzed at the Hanford Site. Although advances in the automation of data analysis have been great, Hanford EN data analysis still demands a highly trained corrosion expert. Neural networks could de-skill the post-data collection analysis procedure and broaden the range of users able to understand and interpret corrosion data. Ultimately, the ability to de-skill data the data analysis process will make or break the use of EN as a plant monitoring tool on a wide scale.

Available in PDF, EPUB and Kindle. Book excerpt: Corrosion remains one of the key issues affecting the performance and availability of nuclear power plants. Therefore, reliable in-plant corrosion monitoring methods are essential both for the future operation of existing plants and to ensure the safety of future nuclear waste disposal systems. In two parts, this book was stimulated by a workshop organised by EFC Working Party 4 on Nuclear Corrosion and the European Cooperative Group on Corrosion Monitoring of Nuclear Materials (EGC-COMON). The first part deals mainly with research into the detection of stress corrosion crack initiation in nuclear power plant environments (essentially high temperature water at around 300 °C) by various methods, particularly the electrochemical noise technique but also including the electrochemical impedance, acoustic emission and direct current potential drop methods. The second part addresses the goal to develop in-situ techniques and includes examples of the application of electrochemical corrosion potential monitoring. This book will be of particular interest to scientists and engineers concerned with the mitigation of corrosion in nuclear systems.
