Types of Radioactive Shipments

Uranium ores

Isotopesp– Medical– Industrial– Research

Weapons-related materials

Radioactive “waste”– Spent fuel (SNF)– High level waste (HLW)– Transuranic waste (TRU)– Low-level waste (LLW)– Mixed low-level waste– Reactor components– Uranium mill tailings

The Transportation Challenge

Spatial diversity of shipping origins

M t fMany waste forms

Varying volumes to be shipped

UncertaintiesUncertainties– Where to ship?– When to ship?

Radioactive Materials Transport Regulators

U.S. Department of Transportation– Training– Packaging– Labeling/placarding– Shipping papers– Loading/unloading

Nuclear Regulatory CommissionNuclear Regulatory Commission– Package design & performance– Safeguards & security

Oth (USPS OSHA EPA IAEA IMO ICAO)Others (USPS, OSHA, EPA, IAEA, IMO, ICAO)

Responsibilities of Shippers & Carriers

Shipper– Classifies & packages radioactive materials– Marks & labels packages– Completes & signs shipping papers– Selects carrier

Carrier– Reviews shipping papersReviews shipping papers– Placards vehicle– Stows & secures package– Complies with driver training and routingComplies with driver training and routing

requirements– Follows vehicle safety requirements– Reports incident (if one occurs)p ( )

Mode Selection

Rail– Regular train– Dedicated train

Truck– Legal weight– Overweight– Heavy haulHeavy haul

Barge

Intermodal

Factors Affecting Mode Selection

C &Container size & weight

Characteristics & composition of radioactivecomposition of radioactive contents

Shipping distanceShipping distance

Availability of transportation facilities & infrastructurefacilities & infrastructure

RoutingHighway (DOT HRCQ Routing Regulations)Highway (DOT HRCQ Routing Regulations)

Vehicles operate over preferred routes– Interstate highway system, including bypasses or beltways

– A state or tribe may designate alternative routes

Alternative route selection based on multiple criteriaT l ti– Travel time

– Accident rate

– Population density & special events

– Temporal considerations (time of day, day of week, season)

– Continuity of operations

RailRail

There are no federal rail routing regulations

Standard rail industry practicesStandard rail industry practices– Minimize time, distance, number of carriers, interchange points

– Maximize use of best track

Operational Issues

Permits and fees

Advance notification

Inspections

Experience to Date

– Roughly 3,000 shipments in the U.S. during the past 30 years

– 738 Navy container shipments, over 1 million miles since 1957over 1 million miles since 1957

– Average 650 shipments per year in France and Britain

– There has never been a release of radioactive material harmful to the public or the environmentto the public or the environment

Perceived Relative Risks of Energy Sources

Considering the risks of normal operations and potential accidents, how do you rate the risks to society and the environment from these sources of energy?ate t e s s to soc ety a d t e e o e t o t ese sou ces o e e gy
