Integrate Engineering and Manufacturing and
Increase Modularization for Affordability
Establish a cost effective process that ensures the design is complete, material is available and work packages are available to support construction start
Develop a cost effective construction plan for low rate production
Increase modularization – (maximize 1 - 3 - 8 Rule)
Reduce the number of design changes identified during construction
3rd ship learning on first hull
Achieving these objectives requires:
Active participation of manufacturer and constructor on design team
Tool set to perform integrated design and manufacturing
Earlier funding of certain activities made part of the design process
Rigorous program management

Objectives of Modularization in Nuclear
Plant Construction – not just “reactor”
● Reduce critical path schedule by implementing a parallel
construction approach. More predictable manufacturing schedule.
● Take the fabrication work to the centers of skilled labor.
● Reduce fabrication cost and on-site duration through improved
productivity.
● Improved quality through standard shop procedures and
consistent material traceability.
● Reduces on-site safety risks.
● Standardization and repetition aids learning curve and fleet cost
reduction.
● Incorporate piping, instrumentation and electrical systems into
modules (increased outfitting).

Module Configuration and Construction
is a Different Process
• Requires increased coordination and use of electronic models by
designers, planners and constructors
• Multi-system and multi-discipline integration of design, fabrication
and test — by area, not system
• Requires schedule and planning rigor—manufacturing assembly and
erection plans incorporated from the beginning of the design
• Standardization is fundamental
• Fixtures, Accuracy Control and 3D measuring is a backbone
• Tolerance budgeting is mandatory
• Neat cuts are expected—extra stock planned on case-by-case basis
• Large assemblies are cut prior to installation based on as-built data
