On December 14, 2004, the Galena City Council accepted a proposal from Toshiba to test their new 10 megawatt Toshiba 4S (Super Safe, Small and Simple) “nuclear battery” reactor design, which would require only minimal staffing. If the reactor is successfully licensed, Toshiba will install it free of charge by 2012. It is expected to provide electricity for $0.05–$0.13/kWh, which factors in only operating costs. On paper, it has been determined that the reactor could run for 30 years without refueling.
The liquid sodium cooled reactor would heat steam to 500 °C (932 °F) and would be located in a sealed concrete cylindrical vault 30 m (98 ft) underground, while the above-ground turbine building would be 22 × 16 × 11 m (72 × 52.5 x 36 ft) in size. The generation plant would provide a more-than-sufficient ten megawatts of power to the community of Galena.
Toshiba intends to sell more 4S reactors in Alaska and the rest of the United States if the Galena project succeeds.
As of 2010, the project is still in its final planning stages with final regulatory submission planned for October 2010. The City Council passes a resolution every six months reaffirming the community's support for the reactor.
