Reactor Vessel
|
| BGRR (Brookhaven) |
Mechanical; dry unbolting and cutting (not completed as of 11/30/05)
|
TBD; dry mechanical segmentation
was planed for 2006 - 2007. |
| Big
Rock Point |
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). |
|
Connecticut
Yankee
(Haddam Neck)
|
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.
|
|
EBWR (Argonne)
|
Thermal (underwater and dry).
|
Mechanical; turning (dry),
Milling (dry).
Abrasive Water Jet (dry).
Thermal (dry). |
| Elk
River |
Size
reduced by underwater plasma torch and explosives. Disposed of in
waste liners. |
Size
reduced by underwater plasma torch and disposed of in waste liners. |
| Fermi
1 |
Believe mechanical cutting
remove most of the internals. |
Intact removal planned for
no earlier than 2010. |
Fort St. Vrain
(Pre-stressed Concrete RV [PCRV]) |
Long Handle Tools (underwater),
Some MDM |
Diamond Wire (dry),
Underwater divers using hand tools, Oxilance (dry). |
| Hallam |
|
|
| La Crosse |
Internals will be shipped inside RV. |
RV was to be removed
whole. Looking for status update. |
| Maine
Yankee |
Abrasive Water Jet (underwater) and Mechanical
(underwater) |
Removed whole. |
| Millstone
1 |
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 remote
removal, milling (dry; high dose). 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;
low dose).
|
N/A (swimming pool type). |
| Piqua |
|
|
| Rancho Seco |
Mechanical; sawing (underwater)
with rotary and reciprocating blades. Diamond wire cut for RV Head.
|
Abrasive
Water Jet (dry) for size reduction. The owner self performed the cutting. |

Thermal (underwater).
Possibly Abrasive Water Jet had limited use.
Some internals still in place. |
Still in place. D&D to be completed with unit-1 (2034)

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.
