50 YEARS AFTER SHUTDOWN, FORT GREELY, ALASKA SM-1A NUCLEAR PLANT BEING DISMANTLED   In October 2023, the Baltimore District U.S. Army Corps of Engineers announced their decision to begin the decommissioning and dismantlement of the SM-1A Former Nuclear Power Plant, located at Fort Greely, Alaska. This year, just over 50 years after its final shutdown in 1972 and following the removal of the radioactive reactor components last year, the building that housed the reactor and the vapor containment structure will be dismantled.    Program Manager Brenda Barber said the original plan was to erect a large weatherproof enclosure over the structure to facilitate working year-round, but that raised concerns about potential earthquake, snow, and wind damage, “and whether or not that weather enclosure would stay stable on top of those conexes during some of the severe weather that occur...” That led the Corps’ team to reconsider how to cover the plant with the enclosure and the vapor containment (VC) structure that towers over the facility. Now the plan is to eliminate some of the height concerns this summer - particularly with the vapor containment structure and remove an old Quonset Hut that sits next to the plant. This will allow the tent to completely encompass the site and allow the demolition work to continue through the winter. Ms. Barber said the Corps needs approval from the Army Reactor Office before work under the new schedule can begin. If they get the go-ahead, demolition will start this summer with trucks hauling away debris starting in the fall. These trucks will be carrying what is called an intermodal container, similar in size and look to a SeaLand container that you typically see on a barge. Re-sequencing of the work; however, requires changes that were not originally scheduled for this summer and fall - such as the asbestos removal this year. Therefore, both demolition waste and asbestos removal will occur this August and be monitored by the Army Corps of Engineers. The debris being removed will be metal and wood-basically construction debris, but the other materials removed will be classified as low-level radioactive waste. An average of two trucks per week will transport containers to Fairbanks, where they’ll be transferred to Alaska Railroad cars for delivery to Anchorage or Whittier, Alaska. From there, they’ll be barged to Seattle, then railroaded to a hazardous waste facility in Texas. Barber says the re-sequencing of work should enable the Corps to complete the dismantling and decommissioning of the power plant by the end of 2029. She says the agency will hold public meetings on the new schedule in July or August to let the public know about the new plan for dismantling the old SM-1A. #energyindustry #powergeneration #nuclearenergy #nuclearpower #renewableenergy #renewables  Photo Credit: US Army Corp of Engineers
