QUESTION:

Followup of list of NPPs with RPVs forged by Rotterdam Dockyards (RDM)

Jeff, For Surry 1 and 2, did RDM make the plate for the RPVs or did it just weld together the plates supplied by someone else?

Thank you, Jon From: Poehler, Jeffrey Sent: Monday, August 13, 2012 4:00 PM To: Hardles, Robert; Fairbanks, Carolyn

Watts Bar 2 hasn't operated yet... but may soon. Surry 1 and 2 were welded by Rotterdam but of plate not forgings.

Mystery solved. The numbers work out now. But which is the plant that has never operated.... or s that one not on this list?

Pat, Verification from DORL of U.S. NPPs with RDM reactor pressure vessels is below.

Yes except for the BWRs, Fermi &

Quad, No.

Jon:

Below is the requested info re: RPVs forged by Rotterdam Dockyards (RDM).

With this e-mail I consider the question to be answered. If you need further info, please send e-mail to me and cc:

Michele Evans.

V/R s

Site/Unit(s)

Question: Were RPV(s) forged by Comments Rotterdam Droogdok Maatschappij Catawba 1 Yes McGuire 2 Yes North Anna 1 Yes North Anna 2 Yes 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.

Sequoyah 1 &

Yes Section 5.4.2, first sentence (Page 5.4-2), of the SQN 2

UFSAR states that "The reactor vessel manufactured by DeRotterdame Drodgdak Mattschappu N.V. (The Rotterdam Dockyard Company) is cylindrical with a welded hemispherical bottom head and a removable, bolted flanged and gasketed, hemispherical upper head."

So, to answer your question, Yes, the Sequoyah Units 1 and 2 reactor vessels are forged by Rotterdam Dockyards.

Surry 1 Yes Surry 2 Yes Watts Bar 1 &

Yes 2

PMs:

(Tasking from Michele Evans)

Please read below and attached.

Action: Ask the licensees of the units below to verify If their units Reactor Pressure Vessel(s) were forged by Rotterdam Droogdok Maatschappij (also referred to as Rotterdam Dockyards or RDM). The RPV forgings may have been welded together by another company such as B&W. NRC is interested in who forged the parts Due to the quick turn around requested and the evolving nature of the issue, we suggest you call your licensing contact, discuss the issue and get a call back with the answer. We understand the licensee would like some context with the question, feel free to send attached to the licensee. We actually suspect this issue is already on their radar screen.

Due: COB today..

Any questions, just call me.

BCs - if the primary PM for the site is out today, forward to the backup PM.

FYI, this tasking does not violate the Paperwork Reduction Act due to small number of (<10) requested responders.

REQUEST: Followup of list of NPPs with RPVs forged by Rotterdam Dockyards (RDM)

Sean, Question for PMs to ask licensees is; Was your plants' RPV forged by RDM (Rotterdam Dockyards) ?

288

The RPV forgings may have been welded together by another company such as B&W.

NRC is interested in who forged the parts.

NRC is Interested because the of UT indications recently found on the RPV forgings at Doel 3 NPP in Belgium. The Doel 3 licensee, Electrabel, provided the below table of NPPs with RPVs forged by Rotterdam Dockyards (Only Belgium and U.S. included in this email. There are additional plants/countries).

This is preliminary information the accuracy of which the NRC wants to confirm for U.S. NPPs.

Reactor Pressel Vessels forged by Rotterdam Drooadok MaatschaoDij (also referred to as Rotterdam Dockyards or RDM) o The Doel 3 and Tihange 2 RPVs were forged by RDM, which according to the Licensee Electrabel provided some 20+ vessels In Europe and the US.

o The table below gives an overview of these RPVs (this list has been established by the licensee and could contain errors or omissions).
