NBCRightNow.com -- In response to a nuclear safety board's input to an Oregon senator about the possible risk of explosion at the Hanford site, the Department of Energy says the tanks are ventilated and monitored.
The Defense Nuclear Facility Safety Board (DNFSB)'s reported to Senator Ron Wyden the possible risk of explosion due to hydrogen gas build up inside Hanford's double-shell tanks (DSTs).
The DOE has released the following statement:
"All DSTs are actively ventilated, which means they have blowers and fans to prevent hydrogen gas build-up. These ventilation systems are monitored to ensure they are operating as intended. Additionally, consistent with the DNFSB recommendation, for even greater safety, DOE instituted an improved testing and monitoring system to allow for direct monitoring of the tank ventilation system in February. DOE is absolutely committed to ensuring the safety of Hanford's underground tanks."
