Current State of Calculations

• The listed calculations are in varying states of completion.

           - Completed final calculations
           - Completed preliminary calculations
           - In progress calculations

• Calculations consider loading combinations applicable to fatigue as required by the design specification.
• Calculations consider applicable primary and secondary stresses (Level A & B).
• Calculations are performed in accordance with Section 111 of the ASME Boiler and Pressure Vessel Code (2013 Edition) 3 PM-1218-63889-NP Revision: 0 Copyright 2018 by NuScale Power, LLC.
