Report: New York state adding 1 GW of nuclear to fleet
New York Gov. Kathy Hochul has instructed the state’s public electric utility to add at least 1 gigawatt of new nuclear by building a large-scale nuclear plant or a collection of smaller modular reactors, according to the Wall Street Journal.

The feedback reactivity measurement was conducted in the Monju Core Confirmation Test in 2010. Two reactivity parameters related either to power and to the core inlet coolant temperature were evaluated within 5% accuracy based on the reactivity measured with the inverse kinetics technique. We confirmed that this advanced method is applicable to the fast reactor operation and shorten the duration of the experiment for the feedback coefficients evaluation.
