Tim Griesbach

• Mr. Griesbach has over 30 years of experience in materials behavior and structural integrity of major nuclear components. He specializes in technical consulting utilizing state-of-the-art technologies for mitigating and resolving material degradation concerns in nuclear reactor vessels, internals, piping, and other major components.
• In charge of numerous EPRI projects to develop tools for managing aging effects such as fatigue and reactor vessel embrittlement in nuclear pressure vessels.
• Authored many reports and technical papers on maintaining structural integrity of nuclear plant components, materials toughness and embrittlement prediction models, databases for monitoring vessel material properties, and strategic planning for license renewal.
• Interfaced with utilities, NEI, and NRC to resolve critical industry issues such as Pressurized Thermal Shock in PWRs and Integrated Surveillance Programs for BWRs.
• Project team leader for successful competitive bids on major industry projects for reactor vessel thermal annealing, PWR internals aging management for license renewal, BWRVIP Integrated Surveillance Program, and probabilistic methods for developing operating P-T limit curves.
• Conducted workshops and utility training classes for managing reactor vessel integrity, nuclear plant surveillance programs, fracture mechanics for nuclear applications, and calculating plant operating P-T limits.
• Participated in strategic planning sessions, and developed technical justifications for resolving key plant issues at Calvert Cliffs 1&2, H. B. Robinson 2, Kewaunee, Beaver Valley 1, D. C. Cook 1&2, McGuire 1&2, Catawba 1&2, and Farley Unit 2.
  Part of a team that developed industry strategic plan for aging management of PWR vessel internals under the EPRI Materials Research Program.
