Inspection Preparation for ModulesInspection Preparation for Modules
• In-house fabrication and module expertise leveragedin creation of Global Modular Solutions– Shaw Fabrication & Manufacturing maintained ASME certification
for all activities related to construction of nuclear components – Assembly of modules in manufacturing setting will provide
consistent quality, reduce construction site activity– Fabrication of assemblies at one location will simplify
some NRC inspection activity
