Constellation considers advanced nuclear in Maryland
Constellation is considering adding 2,000 MW of nuclear energy at Calvert Cliffs, located on Chesapeake Bay near Lusby, Md., which would effectively double the site’s output, according to the company’s near- and long-term project proposals submitted to the Marland Public Service Commission this week.

The maximum fraction of 3He recoverable from deuterium-based plasmas (to fuel D-3He fusion reactors) is investigated, and optimal plasma conditions are identified. The upper bound to the fraction of 3He recoverable from ignited plasmas is ∼80%, corresponding to one 3He atom per 50 MeV of fusion energy, but recovery efficiency is very sensitive to the plasma energy balance. Effects of enhanced radiation losses, tritium assistance, ion/electron temperature split, plasma temperature and density profiles, and external plasma heating are examined. It appears possible to recover ∼70% of the 3He produced in realistic driven semi-catalyzed deuterium (SCD) plasmas, at 70 MeV per atom. This suggests interesting possibilities for the symbiosis of SCD synfuel factories with satellite D-3He reactors for the generation of electricity.
