Reducing the Hazards from Stored Spent Power-Reactor Fuel in the United States, by Robert Alvarez

Nuclear Waste Cask



Summary
In this report, in 2003 Alvarez et al. recommended that all U.S. spent fuel older than five years should be placed in dry, hardened storage containers, greatly reducing the fire risk if water was drained from reactor cooling ponds. Casks should be placed in either thick-walled structures or in earthen berms capable of withstanding plane and missile impacts. We estimated this could be accomplished with existing cask technology in 10 years at a cost of $3 billion-$7 billion. Moreover, future reactors should be designed so that temporary cooling ponds are encased in heavy concrete containment. Such steps were taken by Germany 25 years ago in response to the threats posed by accidental fighter jet crashes and terrorist attacks.
