DOE-STD-3007-93

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

other CSAs.

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."

Controls

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
