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 statistical model is used to interpret the available 232U(n,f) cross-section data in the neutron energy range from 0.003 to 7.4 MeV Below an incident neutron energy of ≈ 1 MeV, the nonthreshold energy dependence of the 232U(n,f) cross section is interpreted in a double-humped fission barrier model, the inner barrier of fissioning nucleus being ≈1 MeV lower than the outer one, as anticipated with the shell correction method calculation.
