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

, senior scientist

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.

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.

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 >

Reactor Core Damage: Meltdown

, director, Nuclear Safety Project

Disaster by Design/Safety by Intent #26

Disaster by Design

We often talk and write about equipment failures and/or worker mistakes that increased the chances of reactor core damage. And much is reported about damaged reactor cores, such as during the five years since three reactor cores at the Fukushima Daiichi nuclear plant in Japan became damaged. This commentary explains how a reactor core overheats and melts down. Read more >

Perils of New Nuclear Fuel: Part 4 – Grand Gulf’s Painted Water

, director, Nuclear Safety Project

Fission Stories #189

The previous two Fission Stories commentaries (#187 and #188) described problems at the Grand Gulf Nuclear Station near Port Gibson, Mississippi involving new fuel bundles stored in the new fuel vault and later in transferring them into the spent fuel pool. This post caps the trilogy by describing a problem encountered with the new fuel bundles in the spent fuel pool. Read more >
