1.2.6.2 Safety Analysis Summary
Potential hazards associated with the receipt, storage, transfer and shipment of waste
containers are radioactive materials (TRU (including residues that are to be disposed of as TRU
waste) and low-level waste drums and metal crates, wooden LLW crates); kinetic energy
(e.g., electric forklift trucks, transport vehicles); potential energy (e.g., stacked containers,
cranes); material handling (e.g., dock, container movement); and other hazards (e.g., hydrogen
explosion, degraded tunnel). Various controls are in place to prevent or mitigate the potential
hazards. Trained and certified operators are used during radioactive waste container transfer
operations. These personnel are familiar with the procedures used for receiving, transferring and
shipping waste containers. Radiation Operations personnel are used to provide exposure rate
surveys prior to and after operations involving the movement of radioactive waste containers. In
addition, trained personnel are familiar with contingency procedures in case there is an incident
involving a waste container.

Conduct of receipt, storage, transfer and shipment of radioactive waste may introduce
hazards and accident initiators (e.g., fires, spills) that would involve the release of MAR. These
activities are evaluated in the hazard and accident analyses as to their involvement with
hazardous materials and potential accident scenarios. Transferring of materials involves the
