Director, Nuclear Safety Project

Mr. Lochbaum received a BS in Nuclear Engineering from the University of Tennessee in 1979 and worked as a nuclear engineer in nuclear power plants for 17 years. In 1992, he and a colleague identified a safety problem in a plant where they were working. When their concerns were ignored by the plant manager, the utility, and the Nuclear Regulatory Commission (NRC), they took the issue to Congress. The problem was eventually corrected at the original plant and at plants across the country. Lochbaum joined UCS in 1996 to work on nuclear power safety. He spent a year in 2009-10 working at the NRC Training Center in Tennessee. Areas of expertise: Nuclear power safety, nuclear technology and plant design, regulatory oversight, plant license renewal and decommissioning

Cooper: Nuclear Plant Operated 89 Days with Key Safety System Impaired

The Nebraska Public Power District’s Cooper Nuclear Station about 23 miles south of Nebraska City has one boiling water reactor that began operating in the mid-1970s to add about 800 megawatts of electricity to the power grid. Workers shut down the reactor on September 24, 2016, to enter a scheduled refueling outage. That process eventually led to NRC special inspections. Read more >

Turkey Point: Fire and Explosion at the Nuclear Plant

The Florida Power & Light Company’s Turkey Point Nuclear Generating Station about 20 miles south of Miami has two Westinghouse pressurized water reactors that began operating in the early 1970s. Built next to two fossil-fired generating units, Units 3 and 4 each add about 875 megawatts of nuclear-generated electricity to the power grid.

Both reactors hummed along at full power on the morning of Saturday, March 18, 2017, when problems arose. Read more >

Nuclear Regulatory Commission: Contradictory Decisions Undermine Nuclear Safety

As described in a recent All Things Nuclear commentary, one of the two emergency diesel generators (EDGs) for the Unit 3 reactor at the Palo Verde Nuclear Generation Station in Arizona was severely damaged during a test run on December 15, 2016. The operating license issued by the Nuclear Regulatory Commission (NRC) allowed the reactor to continue running for up to 10 days with one EDG out of service. Because the extensive damage required far longer than the 10 days provided in the operating license to repair, the owner asked the NRC for permission to continue operating Unit 3 for up to 62 days with only one EDG available. The NRC approved that request on January 4, 2017.

The NRC’s approval contradicted four other agency decisions on virtually the same issue. Read more >

Oyster Creek Reactor: Bad Nuclear Vibrations

The Oyster Creek Nuclear Generating Station near Forked River, New Jersey is the oldest nuclear power plant operating in the United States. It began operating in 1969 around the time Neil Armstrong and Buzz Aldrin were hiking the lunar landscape. Read more >
