Since the early 1960s, the U.S. has safely conducted more than 3,000 shipments of spent nuclear fuel without any harmful release of radioactive material. This safety record is comparable to the worldwide experience where more than 70,000 metric tons of spent nuclear fuel have been transported since 1970 - an amount approximately equal to the total amount of spent nuclear fuel that would have been shipped to Yucca Mountain. However, cities were still concerned about the transport of radioactive waste on highways and railroads that may have passed through heavily populated areas. Dr. Robert Halstead, who was a transportation adviser to the state of Nevada since 1988, stated regarding transportation of the high level waste, They would heavily affect cities like Buffalo, Cleveland, Pittsburgh, in the Chicago metropolitan area, in Omaha. Coming out of the south, the heaviest impacts would be in Atlanta, in Nashville, St. Louis, Kansas City, moving across through Salt Lake City, through downtown Las Vegas, up to Yucca Mountain. And the same cities would be affected by rail shipments as well. Spencer Abraham (DOE) on the other hand has stated, I think there's a general understanding that we move hazardous materials in this country, an understanding that the federal government knows how to do it safely.
