A proactive approach to reactor vessel aging management
Unit 2 at the Prairie Island nuclear power plant near Red Wing, Minn., underwent an outage in fall 2023, which included extensive work on the reactor vessel using a novel approach to replace baffle-former bolts and lower radial clevis insert bolts. The work relied on extensive analysis beforehand to determine which bolts to replace such that only the new bolts were structurally credited for performance of their safety function. This proactive approach eliminated the need for costly contingencies associated with inspections.

A method for optimizing controlled nuclear fusion in an unstructured target using low-energy particles (e.g., hydrogen) is discussed. The main idea of the method is the use of quasi channeling of such particles in a thin single-crystal film of a graphene type located near the surface of an unstructured target made of an optimal isotope for fusion (e.g., natural Li). Such motion at an optimum particle energy of approximately 500 eV leads to the formation of a coherent correlated state of these particles with very large fluctuations of the transverse energy up to 50 to 100 keV in this film and in the adjacent part of the target. The interaction of these particles with target nuclei leads to the stimulation of effective nuclear fusion p(Li7,α)He4.
