New York takes two more steps toward nuclear
In 2025, New York Gov. Kathy Hochul was a vocal supporter of new nuclear development in the state. In October, she called on the New York Power Authority (NYPA)—the state’s public electric utility—to add 1 GW of new nuclear.
At the tail end of December, New York made more nuclear progress on three fronts. Hochul signed an agreement with Ontario Premier Doug Ford to collaborate on new nuclear development, Ontario Power Generation (OPG) signed a memorandum of understanding with the NYPA, and New York finalized its 2025 energy plan.

Operating experience with the Molten-Salt Reactor Experiment (MSRE) has demonstrated the excellent compatibility of the graphite-Hastelloy-N-fluoride salt system at 650°C. Several improvements in materials are needed for a molten-salt breeder reactor with a basic plant life of 30 years; specifically: Hastelloy-N with improved resistance to embrittlement by thermal neutrons; graphite with better dimensional stability in a fast neutron flux; graphite that is sealed to obtain a surface permeability of <10-8 cm2/sec; and a secondary coolant that is inexpensive and has a melting point of ∼400°C. A brief description is given of the materials work in progress to satisfy each of these requirements.
