“H-Tank Farms: SRR has been conducting heel removal in Tank 15. Tank 15 is an old-style tank that had 26 previously identified leak sites. During a recent inspection using digital photography, SRR identified six new leak sites. Five of these are inactive, but a small stream of liquid is spraying from one site. The flow rate is below the design basis leak rate and the annulus level has remained unchanged. If the sludge level in the tank supports it, SRR would like to pump ~220 kgal of waste out of the tank to lower the waste level to below the active leak site.”
