ITH MP1 is replaced today with a new style pump.The new pump is 0.75 inch higher than  old pump on inlet and exhaust so a new solid inlet adapter  (KF50-25) has to been used. For future secondary pump ITH MP1S replacement, we need a new adapter 0.75 inches shorter as well.   The new pumps is started . Everything works fine. Old pumps is drained , bagged, and stored in TH B2 level. All radioactive garbage produced during the job are bagged , tagged, and stored in TH as well.
