Two schemes have been proposed to replace the aging tritium production facilities at Savannah River, South Carolina. The reactors at that site have been operating for well over a quarter of a century, producing tritium for national defense programs. But serious questions regarding safety and other issues have arisen. The U.S. Department of Energy and the federal government have reiterated their plan to build a heavy water reactor and a high-temperature gas-cooled reactor at a cost of about $7 billion as replacements for the Savannah River facility. A group of scientists from national laboratories, on the other hand, have proposed the use of a linear accelerator to accelerate protons to produce neutrons to be used to produce tritium in lithium targets. They contend that the capital cost of this accelerator tritium producer is competitive with that of the reactors, but the operating cost may be high unless it is located in a region where the cost of hydropower is low. Yet another scheme is proposed that is safe and potentially less expensive than the other two. It relies on existing or rapidly developing laser technology to drive a magnetically insulated inertial confinement fusion device, which has already produced copious amounts of neutrons that could readily be used in producing tritium.
