What is different from OL1 / OL2 projects?

Finnish Nuclear Safety requirements and European utility requirements vs. US Reg. guides

New regulatory reguirements related to severe reactor accidents and airplain crash

Strict Regulatory control Number of subcontractors very high ->

project management and quality control more demanding

No strikes
