Utilize a Six Sigma Black Belt to statistically evaluate LFL monitor reliability and determine the failure rate based on the existing technology.
Revise the tank uncertainty calculation and surveillance to include a wider "Required Accuracy" range like the other tanks LFL monitors "Required Accuracy" ranges.
Evaluate minimizing the "Calibration Staff" for the LFL monitors, i.e., establish a small qualified crew of maintenance personnel who are allowed to calibrate the LFL monitors.
Also, submit DSA change request to require installed monitors only when tanks are in agitation e.g., slurry pump operation, salt dissolution, interstitial liquid removal. When in static state, utilize the portable LFL measurement instrumentation. With appropriate basis, this could result in elimination of installed LFL monitoring equipment on specified tanks.
