7 Nuclear Promise & Obsolescence The Nuclear Promise outlines three strategic areas of focus as follows: Maintain Operations Focus Safety is a top priority, safety as it pertains to advancing reliability, which is fundamental to continued operations. Increase Value Generation of additional revenue, valuing unrecognized attributes : i.e. recuperating lost megawatts attributed to degradation of critical systems due to valve performance. Improve Efficiency Identifying focus areas, improving efficiency of industry oversight, evaluating enablers for cost reduction, while contributing to the 30% industry cost reductions. i.e. improving and maintaining efficiencies attributed to performance of critical systems due to equipment by elimination of leakage caused by application obsolescence 1/31/ ValvTechnologies.

8 Nuclear Promise & Obsolescence Obsolescence The Nuclear Utility Obsolescence Group Charter s purpose is to create an environment where nuclear utilities can mutually identify obsolete items and potential replacements, with a focus on long term equipment reliability solutions to reduce station risk and vulnerabilities. ValvTechnologies is dedicated to providing the industry with products and services which can strongly contribute toward these important industry goals. Our durable Zero Leakage products, the latest designs in isolation, and control technology can add to the operating fleet valuable areas for improvement through: The elimination of leaks causing system and equipment degradation, Recuperating lost megawatts, Drastic reductions in maintenance and reductions in costly spares inventory 1/31/ ValvTechnologies.

20 Ultrasonic Emission Testing ValvTechnologies tests valves for Ultrasonic Emissions and correlates the test results to a vast database of valves with known leakage rates to provide a mass-flow rate of leakage for the subject valve. The process was verified accurate by an independent laboratory. Additionally, using the mass-flow rate of leakage, ValvTechnologies calculates the impact of the leaking valve on plant system efficiency in terms of Mw output improvement 1/31/ ValvTechnologies.

28 Conclusion It is very important to understand this is a long term solution to a long term problem. Although the recovery and associated cost savings overview is summarized as an overnight payback it doesn t require wholesale change-out of hundreds of valves all at once. Measurable savings are immediately realized Tools are available to identify leakage, quantify losses to assist Operations and Maintenance to once and for all cease the practice of forever fixing it versus fixing it forever. The first step is to identify and quantify those losses, and then plan the next step in the road to megawatt recovery by addressing Application Obsolescence and contributing to the Nuclear Promise! 1/31/ ValvTechnologies.
