TOW anti-tank missiles can be fired from vehicles, or even shoulder-fired. Large numbers are reportedly loose and unaccounted for on the international black market.In a Global Security Newswire article entitled "Industry, Activists at Odds Over Security Risks of Interim Waste Storage," Douglas P. Guarino quotes Beyond Nuclear's Kevin Kamps about the risks of high-level radioactive waste, including during both on-site storage, as well as during transportation. Kevin referred to a 1998 test conducted at Aberdeen Army Proving Ground in Maryland, which showed that even the so-called "Cadillac of dry casks," the German CASTOR, could not withstand an anti-tank TOW missile attack (TOW is an acronym which stands for "Tube-launched, Optically-tracked, Wire command data link, guided missile"). Most U.S. dry cask systems have much thinner metallic walls than the CASTOR. Kevin reiterated the call by over 150 environmental groups, for Hardened On-Site Storage of irradiated nuclear fuel, rather than a risky, rushed radioactive waste shell game on the roads, rails, and waterways.
