The Washington PostThe Nuclear Regulatory Commission is routinely waiving fire rule violations at nearly half of the nation’s 104 commercial reactors, even though fire presents one of the chief hazards at nuclear plants.
The policy, the result of a series of little-noticed decisions in recent years, is meant to encourage nuclear companies to remedy long-standing fire safety problems. But critics say it is leaving decades-old fire hazards in place as the NRC fails to enforce its rules.
Fires present a special risk to nuclear plants because they can knock out cables that control-room operators need to safely cool down a reactor. The explosions and fires at Japan’s Fukushima Daiichi plant have shown what can happen when operators cannot activate pumps, valves and other equipment needed to prevent damage to a radioactive core.
The Browns Ferry plant in Alabama, where a devastating cable fire 36 years ago prompted the NRC to adopt tough new fire rules, still doesn’t comply with the requirements to protect cables. Hazards at other plants include unprotected equipment, inadequate fire doors, and missing alarms and sprinklers. To compensate for being out of compliance, plants rely on temporary measures such as stationing workers on a fire watch.
