Dry cask storage is a method of storing high-level radioactive waste, such as spent nuclear fuel that has already been cooled in the spent fuel pool for at least one year and often as much as ten years.Casks are typically steel cylinders that are either welded or bolted closed. The fuel rods inside are surrounded by inert gas. Ideally, the steel cylinder provides leak-tight containment of the spent fuel. Each cylinder is surrounded by additional steel, concrete, or other material to provide radiation shielding to workers and members of the public.
There are various dry storage cask system designs. With some designs, the steel cylinders containing the fuel are placed vertically in a concrete vault; other designs orient the cylinders horizontally. The concrete vaults provide the radiation shielding. Other cask designs orient the steel cylinder vertically on a concrete pad at a dry cask storage site and use both metal and concrete outer cylinders for radiation shielding. Currently there is no long term permanent storage facility; dry cask storage is designed as an interim safer solution than spent fuel pool storage.
Nuclear Energy Institute's Everett Redmond, Director of Nonproliferation and Fuel Cycle Policy, outlines how used fuel assemblies are stored once they leave the spent fuel pool in nuclear power plants.

This is SanOnofreSafety.org founder Donna Gilmore's presentation to the NRC on dry cask nuclear waste storage issues, delivered by invitation as part of an NRC Regulatory Conference held Nov. 19-20, 2014 in Rockville, Maryland. Why are the NRC and Southern California Edison favoring inferior, short-lived, thin-walled, unsafe stainless steel canisters to store San Onofre's tons of nuclear waste in a corrosive seaside environment instead of the long-lasting, thick-walled, top-of-the-line technology available? Gilmore presents a strong case for regulators and utilities to take the lead in setting the highest possible standards for America's growing inventory of radioactive waste that will remain deadly for hundreds of thousands of years longer than human civilization has yet existed. With ...
Energy Northwest recently completed its fourth used nuclear fuel dry cask loading campaign. Nine casks were loaded with 68 used nuclear fuel assemblies each and safely moved to a secure dry cask storage area located adjacent to Columbia Generating Station. Currently, there are 36 dry casks stored on site at Columbia. During the campaign, the Nuclear Regulatory Commission conducted an inspection with no findings or violations.

In November 2010, AREVA successfully conducted a high-impact crash test demonstrating that the company's concrete storage modules, such as those used in the current NUHOMS® dry cask storage system, can withstand intense impact without loss of integrity or safety. The 1:3-scale test simulated the impact of a military airplane jet engine shaft at the most sensitive location on the AREVA TN "TN NOVA(TM)" used nuclear fuel overpack system. In the test, a steel projectile weighing 660 lbs. was fired at a TN NOVA with an impact speed of 534 mph. The test successfully demonstrated that the TN NOVA internal canister, which would contain the used nuclear fuel, remained leaktight after the projectile's impact, and the impact with the ground following the forceful test. The test was conducted by ...

http://fairewinds.org/ja/node/416 08/14/2012 CCTV Host Margaret Harrington and Fairewinds Energy Education's Arnie Gundersen discuss the urgent need to empty spent fuel pools into dry cask storage to prevent a serious but avoidable accident. They also discuss the economic cost to nuclear plants if they where forced to withstand natural calamities, the future of Yucca Mountain, and the radiological contamination caused by depleted uranium weapons.
maybe Dry cask storage is over designed enough since the DOE, NRC, DEQ & DOT demanded they beat the crap out of them in tests & some companys are designing better ones today The transport of casks met with considerable public protest so they are stored at power plants ?! Yucca Mountain nuclear waste repository was defunded In the 1990s, the NRC had to take repeated actions to address DEFECTIVE WELDS on dry casks that led to cracks & cracking related to salt corrosion could occur in 30 years or less http://en.wikipedia.org/wiki/Deep_geological_repository http://en.wikipedia.org/wiki/Nuclear_flask or http://en.wikipedia.org/wiki/Dry_cask_storage http://en.wikipedia.org/wiki/Spent_fuel_pool http://nrc.gov/waste/spent-fuel-storage/diagram-typical-dry-cask-system.html http://public-bl...
Nuclear Hotseat #250: “Chernobyl in a Can” – More Dry Cask Dangers w/Donna Gilmore... This Week’s Featured Interview: Donna Gilmore, head of SanOnofreSafety.org, offers a chilling update on the problems of short term nuclear waste storage, calling the on-site dry storage canisters approved by the Nuclear Regulatory Commission “Chernobyl in a Can.” Numnutz of the Week: Russia risks doubling the reactor lifespan of the Kola nuclear power plant in Murmansk to 60 years so it can produce energy the area doesn’t need. Why? Because the station worked out an “investment plan” because it would be “too expensive to decommission it.” What part of “Chernobyl” do they not understand?
