Possible leak at Hanford’s AZ-101 double-shelled tank

Higher than normal readings Thursday night on a filter at the AZ-101 double-shell tank at Hanford MAY indicate a leak in between the two shells.

A robotic crawler was contaminated after inspecting the space between the two shells of the tank, and according to a statement by Washington River Protection Solutions, the radiation levels were three-times the recommended levels.

One of the workers had contamination on his clothing…which was removed and all workers were cleared to return to work.

Hanford’s AZ tanks were built in 1976 and were only supposed to be used for 20 years, but it’s been over 40 years.
