- May 13, 2001 The Advocate, Baton Rouge, LA Packed Away This detailed article clearly described Dry Fuel Storage planned facility and process at River Bend.
- January 18, 2001 WBRZ Channel 2 News coverage aired discussing Dry Fuel Storage at River Bend Station.
- December 17, 2000 Times Picayune New Orleans, LA Mountain of Controversy (Yucca Mountain), communicates River Bends intent to use storage canisters, and that construction of the outside concrete storage area had begun.
There have also been minor references to RBS Fuel Storage in The Advocate urging Louisiana consideration and support of the facility at Yucca Mountain. An example is We Can't Sweep Waste Under the Rug published Feb 28, 2002 which mentions, Louisiana's two nuclear power plants both store their spent fuel on site.
61 April 1, 2002 Emergency Preparedness planning meeting. Dry fuel storage was discussed. 5 Parish Directors, State of Louisiana LOEP (Louisiana Office of Emergency Preparedness) and LDEQ (Louisiana Department of Environmental Quality). This meeting was reported in two newspapers (April 2 and April 5), but Dry Fuel Storage was not mentioned in the articles.

64 For two decades, power plants have been storing nuclear fuel that is no longer useful in large pools power plants are increasingly filling their pools and turning to large outdoor canisters to hold the extra waste.
A photo shows a row of ANOs VSC-24s and notes that a foundation for similar canisters is under construction at Entergys River Bend plant.
When the pool is completely filled, the plant [River Bend] will begin storing rods in 19-foot-tall concrete and steel canisters sitting outside the reactor [building]. Work already has started on the concrete foundation The dry-storage containers that will store waste at River Bend once the plants waste pool is filled will cost Entergy about $5 million a year to maintain, company spokeswoman Diane Park said.
Similar containers [to those River Bend will use] are already in use at Entergys Arkansas Nuclear Power Station in Russellville, Ark., which exhausted its storage pool four years ago.
Already, more than a dozen nuclear plants across the country are using 150 containers for storage.

65 River Bends planned storage facility and process
- A stainless steel canister with a built-in grid to hold the fuel assemblies will be placed inside a transfer cask, a smaller version of a storage cask, and both will be lowered into an area of the spent fuel pool and filled with water.
- While remaining under water, 68 selected fuel assemblies will be lifted by a special crane above the pool and placed in the stainless steel canister. The resting place for each assembly will be predetermined by its age to distribute the heat load.
- A lid will be put on the canister, and the entire load will be lifted out of the pool by an overhead crane. The lid will then be welded in place.
- The crane will then move the transfer cask and its canister of spent fuel through huge doors on the fuel building and place them on top of the "storage overpack," the larger metal-and-concrete storage cask.
- The transfer cask has a removable bottom, which will allow workers to lower the inner canister into the storage cask without exposing the workers to radiation.
- A motorized crawler-type vehicle will deliver the cask to the storage pad.
