Fixing the barriers: How new policies can make U.S. nuclear exports competitive again
The United States has a strong marketplace of ideas on future civil nuclear technology. President Trump wants to see 10 large reactors under construction by 2030 and has discussed making $80 billion available for that objective. Evolutionary small modular reactors based on light water reactor technology are on the market now, and the Tennessee Valley Authority expects a construction permit for a project at its Clinch River Site later this year.

A counter current extraction system is proposed here to recover tritium from 17Li-83Pb. The multiple stage extraction system is used to reduce the resistance to the molecular diffusion in the liquid phase, while a counter current helium purge gas is used to reduce the resistance in the gas phase. To reduce the purge gas requirement and alleviate the tritium containment problem, hydrogen is added to the purge gas. An isotope separation system is designed to separate the hydrogen from the tritium.
