47 MATERIALS PERFORMANCE: VOL. 57, NO. 11 NOVEMBER 2018 The last factor to consider in safely and reliably managing corrosion or integrity issues is sustainability. Sustainability of business models in competitive commodity economies is a lot to ask, but there are sus- tainability expectations that are within the responsibility of a corrosion engineer. The nuclear power industry's approach to stew- ard asset integrity management expecta- tions and commitments in a sustainable and continually evolving manner is worth examining. The industry works to develop normal- ized performance goals and management tools to address the balance of plant corro- sion issues and evaluate program perfor- mance. Most companies use the same or closely similar databases and other tools. This enables strong transferability of expe- rience between plants, companies, and per- sonnel while also feeding into an overall industr y knowledge base. Data mining these repositories can identify trends out- side of observable factors that could lead to innovations in causality or correction. This also ensures that when plants and compa- nies benchmark one another to identify areas for improvement, they share a com- mon language of performance with parallel tools, tactics, and strategies to meet it. Facing the challenge to meet these goals over time and reduce cost, many operating companies are looking to matrix staffing models to share skills, experience, and per- sonnel across different operating plants. This enables a centralized, watchful subject matter expert to provide direction and maintain surveillance over a fleet's integrity challenges with site-cognizant personnel in place to help local management teams mana ge impl em ent ation . Thi s matri x model also allows for increased flexibility to move personnel from one site to another or to st e p into f l e et l ead ership ro l e s as advancement opportunities occur without losing experience from the company's tal- ent pool. The industry 's strong parity of management approaches often points attri- tion or retirement toward other operating companies or service providers to distrib- ute and evolve performance. Lastly, the power industry continues to invest in college recruiting, internships, and science, technology, engineering, and math (STEM) education programs to bring a future generation of innovative minds to bear on the challenges of this vital element of modern infrastructure. New engineers bring new ideas, outlooks, and energies to challenge conventions and reinvigorate the entrepreneurial vision of their mentors and managers to pursue long-term reliability of the public's electrical infrastructure through asset integrity management strategies. Conclusions Considering the scope, age, and vitality of nuclear power generation infrastructure, its asset integrity management programs for balance of plant corrosion provide a comprehensive framework for identifica- tion, inspection, evaluation, control, and mitigation measures to address balance of plant corrosion and its effects for modern industrial operations. Competitive business cultures and environmental sensitivity dic- tate strong economic evaluation and invest- ment models to ensure that concerns are addressed in a sustainable manner. How- ever, the industry's collaborative and self- regulating nature provides a strong culture for proactively identifying and implement- ing innovative integrity solutions. Lastly, awareness and education play a strong role in the long-term viability and sustainability of this industry, including outreach, train- ing, and mentoring programs to identify, acquire, and retain the talent needed to meet these industr y challenges. These impacts, challenges, strategies, and solu- tions provide promise for a sustainable energy future and can also serve as a credi- ble benchmark for other industries seeking a similar outcome. Continued engagement and involvement of future engineers will help us to engineer this future today. References 1 G. Cilluffo, M.
