Nuclear Reactor Fuel Safety: The Waiting Gain

, former director, Nuclear Safety Project

Nuclear power reactors spilt atoms to release energy used to generate electricity. Many of the byproducts formed when atoms split are unstable (radioactive) and release particles or gamma rays in search of stability. These radioactive emissions produce energy. Whether in the core of an operating reactor, in the core of a shutdown reactor, in the spent fuel pool after discharge from a reactor core, or in dry storage after offloading from a spent fuel pool, the energy released from nuclear reactor fuel must be removed before it damages the fuel from overheating. This commentary describes the energy levels associated with nuclear fuel in various locations at various times to illustrate the factors that affect the associated hazard levels. Read more >

UCS in Science: The NRC Must Act to Reduce the Dangers of Spent Fuel Pool Fires at Nuclear Plants

, Acting Director, Nuclear Safety Project; Senior Scientist, Global Security Program

In a Policy Forum article published in this week’s Science magazine, I argue, along with my co-authors Frank von Hippel and Michael Schoeppner, that the U.S. Nuclear Regulatory Commission (NRC) needs to take prompt action to reduce the alarmingly high potential for fires in spent fuel pools at U.S. nuclear plants.

Nuclear Spent Fuel Damage: Pool Accident

, former director, Nuclear Safety Project

Disaster by Design/Safety by Intent #28

Disaster by Design

Disaster by Design/Safety by Intent #26 described a progression leading to meltdown of a reactor core. Disaster by Design/Safety by Intent #27 described damage resulting from reactivity excursions.

This commentary describes a progression leading to overheating damage of fuel in a spent fuel pool. Next week’s post will describe how fuel in a spent fuel pool could experience a reactivity excursion. Read more >
