Components-NRC Meeting Rockville, MD Industry Perspective November 28, 2017

Overview

• Industry Challenges and Current Landscape

• Industry Responds

• Sustain and Innovate

• Additive Manufacturing and Nuclear Energy

• This Moveis anForward explanation of the main idea

Early Plant Shutdowns This is an explanation of the main idea

NATIONAL NUCLEAR ENERGY STRATEGY CREATE THE NUCLEAR IMPERATIVE PRESERVE SUSTAIN INNOVATE THRIVE Appropriately value Create sustainability Innovate, Compete globally nuclear generation via improved commercialize, regulatory framework and deploy and reduced burden new nuclear 7

NATIONAL IMPERATIVES 8

Additive Manufacturing Strengths

• Build 3D objects by layering materials-plastics, metals, living tissues-endless potential

• Enable rapid prototyping

• Integrates sophisticated technologies

• Compliments materials removal processes in manufacturing to achieve final shape and dimensions

Create Sustainability NOW

• Preserve reliability and support long term operation

• Sustain the viability of the operating fleet

- Re-create non-OEM parts or OEM parts where design drawings are unavailable, e.g. pump impeller

- Improve part performance by removing design limitations

- Reduce manufacturing lead times and costs

• Additive manufacturing has established a decade long track record serving secondary side and BOP component needs

Innovate, Commercialize and Deploy New Nuclear

• Demonstrate cost-benefit and establish regulatory acceptance with current applications through ASME and other codes and standards

• Strong collaboration between U.S. industry, national labs and universities

• Opportunities in new plant components, new products, and fuel components

• Production of 316 SS and Inconel demonstration parts

• Low risk fuel components in a reactor by 2018

Moving Forward

• High equipment costs versus potential industry savings

• Part size limitations

• Lack of process standardization

• Process development ongoing

• Final products are near-net-shape

• This Finishing is an steps required to meet dimensional and explanation of surface finish requirements the main idea

Industry Challenge Develop innovative approaches to refine the manufacturing process and minimize investment and production costs, work collaboratively with regulatory and consensus standards bodies to achieve acceptance for broad use. Efficiency gained today supports a platform for future new nuclear deployment.
