RPV preliminary IRS report.final.docx; ACTION: Followup of list of NPPs with RPVs forged by Rotterdam Dockyards (RDM)
High A email chain for your awareness regarding the Quad Cities 2 RPV manufacturing. NRR management polled licensees yesterday to locate RPVs built by Rotterdam Dockyards.
The concern with Doel 3 seemed to be more related to forgings.
Regards.

RE: Inquiry: Quad Cities 1 - RPV Forging Importance: High
Nick.
According to the attached Quad Cities UFSAR Section 5.3.1.2 and Manufacturing History, the Quad Cities, Unit 1 RPV was manufactured entirely by Babcock & Wilcox. The Unit 2 RPV history did not Include any forging at Rotterdam (RDM),
but did Include assembly and welding on portions of the RPV at RDM.
Please let me know if you have additional questions or concerns.
