ATLANTA (AP) — U.S. nuclear regulators may need to shuffle staff as fewer nuclear plants are built and financial pressures prompt utilities to shutter existing plants, U.S. Nuclear Regulatory Commission Chair Allison Macfarlane said Monday.

Macfarlane said NRC officials are in the early stages of researching how to reposition its roughly 3,800-member workforce as the industry’s outlook changes. A recommendation is due in early 2015.
