Contact: Diane Screnci, 610-337-5330 Neil Sheehan, 610-337-5331
Regulatory Commission staff will be available to discuss the 2016
safety performance of the Three Mile Island nuclear power plant,
operated by Exelon Generation Co., during an open house on April 20 in
open house will run from 4:30-6 p.m. at the Londonderry Township
Municipal Building, 783 S. Geyers Church Road. NRC staff responsible for
inspections of the plant, including the site- based resident
inspectors, will be on hand to discuss the plant’s performance and the
NRC’s oversight of the facility.
Three Mile Island Unit 1 operated safely during 2016. As of the end of
last year, the plant had no inspection findings or performance
indicators outside the normal band. As a result, it is currently under
the NRC’s baseline level of oversight, which entails thousands of hours
of inspection each year.
the NRC’s Reactor Oversight Process, the agency gauges plant
performance through the use of color-coded inspection findings and
performance indicators, which are statistical measurements of plant
performance that can trigger additional oversight if exceeded. Any
inspection findings or performance indicators that are greater than
green (very low safety significance) trigger increased NRC oversight.
inspections are performed by two resident inspectors assigned to the
plant. Reviews are also carried out at the site by specialist inspectors
assigned to the agency’s Region I office in King of Prussia, Pa.
