2.7.1 Railcar Loadout and Lidding Operations
These operations involve moving four railcars at a time utilizing a track mobile. The railcars will
enter the loadout building at the northeast comer (through the rail decon area). For discussion
purposes, the first car that enters the building is referred to as Car 4, with all cars that follow
being referred to in a descending numerical order because the last car to enter the building will be
the first car to leave the building. Each car will proceed through five operations necessary for
completion of loadout. These operations include:
.
0 Lid removal and inspection
0 Railcarlining
Loadout
Lidding and decontamination
0 Radiological survey.
The following is a step-by-step description of the operation in the Railcar Loadout Building: 18
Step 1. As the railcars pass through the decontamination area, the lids will be removed and 20
visually inspected to assess their condition and to identify any damages. 21
If the lid is in good condition, it will be placed in a rack located within the decon 23
area and stackedstored until the lid replacement step, after railcar loadout is 24
completed. 25
If a lid requires repair, it will be placed back on Car 1. The railcars then move to
the liner and lid repair area at the southem end of the building where damaged lids
will be removed as needed for repair. - 29
Step 2. Once all of the lids are removed, either in the decon area or the liner and lid repair area,
the cars will be moved to the liner and lid repair area. Car 1 is positioned in the lining area and
lined, with Cars 2,3, and 4 awaiting lining.
Step 3. The cars will advance so that Car 1 is awaiting loadout,* 2 is being lined, and Cars 3 35
and 4 are awaiting lining. 36
