The James A. FitzPatrick nuclear power plant on Lake Ontario in upstate New York is an unattractive pair of industrial-scale boxes that house a reactor, a turbine, and a generator to create electricity. Its blunt and inflexible profile may be an apt metaphor for the challenges facing a growing portion of the U.S. civilian nuclear fleet.
The 838-megawatt, single-unit boiling water reactor has produced power for more than 40 years. But a year ago, it seemed that FitzPatrick’s days were numbered. Single-unit nukes like FitzPatrick can be expensive to run because they lack the economies of scale available to larger multi-unit plants.
Operator Entergy said FitzPatrick’s economics also were hurt by a market structure that often favors renewable energy over baseload sources like nuclear and coal.
