Update: Turkey Point Fire and Explosion

, director, Nuclear Safety Project

An earlier commentary described how workers installing a fire retardant wrap around electrical cables inside Switchgear Room 3A at the Turkey Point nuclear plant in Florida inadvertently triggered an explosion and fire that blew open the fire door between the room and adjacent Switchgear Room 3B.

I submitted a request under the Freedom of Information Act (FOIA) for all pictures and videos obtained by the special inspection team dispatched by the NRC to Turkey Point to investigate this event. The NRC provide me 70 color pictures in response to my request. This post updates the earlier commentary with some of those pictures. Read more >

Florida’s Nuclear Plants and Hurricane Irma

, senior scientist

Will Florida’s two nuclear plants, Turkey Point and St. Lucie, be able to withstand Hurricane Irma?

Florida governor Rick Scott, the utility Florida Power & Light (FP&L), and the US Nuclear Regulatory Commission (NRC) have all provided assurances that they will. But we are about to witness a giant experiment in the effectiveness of the NRC’s strategy for protecting nuclear plants from natural disasters. Read more >

Turkey Point: Fire and Explosion at the Nuclear Plant

, director, Nuclear Safety Project

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 >

Spent Fuel Damage: Pool Criticality Accident

, director, Nuclear Safety Project

Disaster by Design/Safety by Intent #29

Disaster by Design

Disaster by Design/Safety by Intent #26 described a progression leading to overheating and damage to a reactor core, often labeled a meltdown. Disaster by Design/Safety by Intent #27 described the damage to a reactor core that can result from reactivity excursions. Disaster by Design/Safety by Intent #28 and #29 mirror those commentaries by describing how irradiated fuel stored in spent fuel pools can experience damage from overheating and reactivity excursions.

When Safety Relief Valves Fail to Provide Safety or Relief at Nuclear Plants

Disaster by Design: Safety by Intent #6

Disaster by Design

The light water reactors currently operating in the U.S. are either boiling water reactors (BWRs) or pressurized water reactors (PWRs). In both designs, water flowing past the nuclear fuel in the reactor cores gets heated to over 500°F. Water is able to be heated to this temperature because it is pressurized—to over 1,000 pounds per square inch (psi) in BWRs and to over 2,000 psi in PWRs. The 1,000 psi pressure is equivalent to the pressure submerged more than 2,200 feet below the ocean’s surface. Read more >
