Plant/Facility
Reactor Internals
Reactor Vessel
BGRR (Brookhaven)

Mechanical; dry unbolting and cutting (not completed as of 11/30/05)

TBD; dry mechanical segmentation will probably be performed in 2006 - 2007

Mechanical; saws.
(Nut and bolt removal).
(need more information).

Removed whole.
Mechanical cutting (turning), Diamond Wire, and MDM used to cut vessel piping (done dry).
Abrasive Water Jet (underwater).
MDM (underwater).
Removed whole.
CVTR (Parr) Mechanical; dry cutting and unbolting.
Mechanical; dry segmentation awarded, but not started as of 11/30/05.

Thermal (underwater and dry).

Mechanical; turning (dry),
Milling (dry).
Abrasive Water Jet (dry).
Thermal (dry).
Fermi 1 Method to be determined late-2006. Mechanical segmentation possible but intact removal quicker. No earlier than 2007.
Fort St. Vrain
(Pre-stressed Concrete RV [PCRV])
Long Handle Tools (underwater), Some MDM Diamond Wire (dry),
Underwater divers using hand tools, Oxilance (dry).
La Crosse Internals will be shipped inside RV. RV will be removed whole in 2006-2007 by Bigge.
Abrasive Water Jet (underwater) and Mechanical (underwater) Removed whole.
Mechanical (underwater).  
NS Savannah We assume the internals will remain in the vessel. We believe it will be removed whole around 2008.
Omega West Mechanical (dry). Remote disassembly and limited cutting using Plasma Arc and mechanical shears for size reduction. Vessel was removed using remote tools (Track Hoe w/hammer & shear, BROKK w/hammer & shear as bioshield was demolished).
Pathfinder    
Plum Brook 1 (NASA) Mechanical; nut and bolt removal, milling (dry).
Thermal; limited use outside of RV (dry).
Mechanical; milling, turning, and drilling (dry). Semi-remote.
Thermal; lower sections of RV (dry). Hands-on.
Plum Brook MUR (NASA) Mechanical; nut and bolt removal (dry).
N/A (swimming pool type).
Rancho Seco Mechanical; sawing (underwater) with rotary and reciprocating blades.
Currently in progress or recently completed.
Abrasive Water Jet (dry): The owner is self performing the cutting. It will be the fourth pressurized reactor vessel in the United States to have been segmented when completed in 2006.
Saxton Believe intact in Reactor Vessel (RV) Removed whole.
Shippingport Thermal (underwater). Grouted inside Reactor Vessel (RV) Removed whole.
Thermal (underwater). Mechanical; turning (dry).
Thermal; (dry).
San Onofre 1 (SONGS-1) Abrasive Water Jet (underwater).
MDM (underwater).
Removed whole.
Thermal (underwater).
Possibly Abrasive Water Jet had limited use.
Some internals still in place.

Still in place.
Scheduled for 2014 with Unit-1

Intact in Reactor Vessel (RV). Removed whole.
Waltz Will Removed per DP. Removed per DP.
Thermal (underwater). Removed whole.

The purpose of this table is to provide the reader with an overview of what processes were used to segment the reactor internals and reactor vessel at various USA nuclear facilities. Facilities that had intact removal of the reactor vessel and the internals are noted as such. Smaller "swimming pool" type reactors generally will not be listed here.

Please advise of of any errors or questionable information and we will immediately remove it or list our source to verify it is correct.

References used are listed on the Plant/Facility detailed information sheets.

We will add non-USA facilities if we are provided with the information.
