NOTE: Equipment approved by this CSA is limited to (a) Trap F-1202 and various
connecting lines for feed and vacuum, and (b) the transfer line to D-Wing and the safe bottle near
the Room 1021 scrubber.
Final wet vacuum traps (i.e., northwest corner of Room 1022) and the wet vacuum
equipment in the Headhouse fan room, other Room 1021 tanks, D-Wing tanks, and the safe bottle
used in D-Wing as a drain collection for the second double wall section are currently approved by
The operational steps specifically analyzed here are transfers into F-1202 and transfers
from F-1202 to D-Wing tanks. Safe bottle handling and storage, dolly handling and storage, area
cleanup and mopping, etc. are standard area activities that are not unique to this operation. These
are addressed in Y/DD-395, "Basic Nuclear Criticality Safety Guidelines."
The following controls are identified for the above parameter.
· The dimensions of the trap and its location relative to other tanks are fixed by design.
All transfer lines are 1.5" diameter or less. The double-walled pipe sections have
sleeve diameters of either 3" (steel jacket in D-1 Wing and Room 1010 plenum areas
or 4" (CPVC pipe over the Room 1021 fissile storage array).
· A spill or a leak would result in relocation of uranium solution to another safe
geometric configuration. Near the west wall of Room 1021, the solution would spill
into the diked area underneath the storage tanks and other equipment. Over the Room
1021 fissile storage array, the liquid would drain into the 4" CPVC pipe jacket and
drain into a safe bottle in the diked scrubber area. In the Room 1010 plenum or D-1
Wing, the liquid would enter the 3" stainless steel pipe jacket and drain into a safe
bottle in D-Wing. Overfill of this safe bottle, D-Wing tank overfill, or tank or line
