Dave Lochbaum

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

NRC’s Nuclear Maintenance Rule

Disaster by Design/ Safety by Intent #50

Safety by Intent

The Nuclear Regulatory Commission (NRC) identified a disturbing trend in the mid-80s—the number of safety problems caused by inadequate maintenance was increasing. In some cases, ineffective practices during routine maintenance such as replacing worn-out gaskets or lubricating rotating machinery resulted in equipment that had been operating satisfactorily breaking down soon afterwards.

Visit to the Palo Verde Nuclear Generating Station

Last fall, I read something about the Department of Energy (DOE) partnering with the Palo Verde Nuclear Generating Station (PVNGS) on a digital instrumentation upgrade project. The topic interested me for two reasons. Read more >

Nuclear Bathtub Safety

Disaster by Design/ Safety by Intent #49

Safety by Intent

In recent years, Japan’s health ministry initiated a study in response to an estimate that nearly 14,000 people die annually in bathtubs, almost three times the number of people killed each year in traffic accidents in the country.

More recently, the Center for Disease Control and Prevention issued a warning because over a dozen people have died since 2000 working on bathtubs—due to exposure to methylene chloride, a solvent used to clean tubs being refinished.

This commentary addresses figurative rather than literal bathtub safety. Read more >

Oconee Flood Protection Issue

In August 2006, NRC inspectors identified a deficiency in a flood protection measure at the Oconee Nuclear Station in South Carolina. Specifically, the inspectors discovered that workers removed a 6-inch by 10-inch panel in the 5-foot tall flood wall around the Standby Shutdown Facility (SSF) to allow temporary cables to be used during a modification. When the work was completed and the cables removed, the panel was not re-installed.

Nuclear Regulatory Commission Inspector General

The Nuclear Regulatory Commission (NRC) has exclusive authority over nuclear power plant safety in the United States. The NRC asserts this authority by establishing and enforcing regulations intended to manage the risks from nuclear power plants to an acceptably low level. The NRC sanctions plant owners for violations of regulatory requirements. It is essentially the nuclear cop on the nuclear safety beat. Read more >
