... Endemic in both boiling water and pressurized water reactors in the 1970s and early 1980s, stress corrosion cracking, threatened to derail the entire nuclear energy program. But corrosion research performed at universities and by industry and government laboratories resulted in the development of new alloys and the control of chemomechanical parameters, effectively allowing the current fleet of reactors to greatly exceed their expected useful lifetimes.

... The use of current advanced analytical tools, the rapid development of new tools and techniques, expanded computational capabilities and strategies, and, increasingly, systems-oriented approaches for development of materials can open new ways to solve previously intractable corrosion problems. The results of mate rials modeling and simulation R&D activities can be applied to mitigate corrosion challenges.
From page 135...
... The committee concluded that these research demands can be conveniently expressed in the following four grand challenges for corrosion: • Development of cost-effective, environment-friendly, corrosion-resis tant materials and coatings; • High-fidelity modeling for the prediction of corrosion degradation in actual service environments; • Accelerated corrosion testing under controlled laboratory conditions that quantitatively correlates to long-term behavior observed in service envi ronments; and • Accurate forecasting of remaining service time until major repair, re placement, or overhaul becomes necessary -- i.e., corrosion prognosis. Addressing these challenges will demand an integrated body of scientific and engineering research targeted at specific agency needs but coordinated to minimize duplication of effort and to take advantage of synergism.

... Progress in attacking the corrosion grand challenges will require a balanced effort by traditional single-investigator programs and multi-investigator, cross-disciplinary programs to build collaborative systems, including advanced measurement techniques and modern analytical and computational tools. Recommendation: Funding agencies should design programs to stimulate single-investigator and collaborative team efforts and underwrite the costs of realistic test laboratories open to the corrosion community and its collabora tors, including industry researchers.
From page 137...
... Many of the success stories highlighted in Chapter 1 of this report were the result of industrial developments responding to well-understood needs. However, the leadership of corrosion materials re search has declined in recent years owing to the high cost of sustaining such an effort, the uncertainty of finding a successful product application as materials and product sophistication increase, and the move to offshore development and production of engineering materials.
From page 138...
... In many cases, however, these data are not readily accessible because they are contained in obscure, highly technical academic treatises or proprietary data bases. If all of the available corrosion data were accessible, it would be a tremendous asset to the field.1 In molecular biology, databases, algorithms, and computational and statistical techniques have been developed to handle large amounts of data from different biological areas such as the human genome.

... NATIONAL MuLTIAgENCY COMMITTEE ON ENVIRONMENTAL DEgRADATION Conclusion: Corrosion affects all aspects of society, in particular, the areas where the federal government is investing: education, infrastructure, health, public safety, energy, the environment, and national security. Inevitably a thermodynamically driven process, corrosion can, however, be mitigated sub stantially by retarding the rate of degradation.
From page 140...
... Revitalization of the gov ernmental and industrial corrosion research infrastructures will play an important role in reducing the costs of corrosion and better controlling it.
