Tank Farm Management

Located at the Idaho Nuclear Technology and Engineering Center, the high-level waste Tank Farm includes 11 underground stainless steel storage tanks used to store the radioactive liquid waste generated during the reprocessing of spent nuclear fuel and plant decontamination work. No leakage has occurred from the tanks.

The tanks are encased in concrete vaults which have sumps and leak detection. Seven tanks have been cleaned to RCRA standards and have been grouted in place for final closure. The remaining four tanks (three full and one spare) will be cleaned and grouted once the sodium-bearing waste has been removed. Some leaks from transfer lines outside the tanks have occurred, and this drives the current cleanup program. Crews have transferred material from tank WM-190 to WM-187 and washed and grouted inactive lines.

Crews have installed asphalt over a large portion of the tank farm and implemented water diversion methods to prevent water infiltration within the tank farm. Once all tanks have been emptied and grouted in place, a permanent cover will be installed over the entire tank farm.
