13. Problem

Recent pneumatic testing on the encasement of SL-167 has determined that it cannot maintain pressure, and therefore cannot be used to compliantly transfer waste. Recent visual inspection of SL-168 (the back-up slurry line) and pneumatic testing have identified additional work to be performed in order to attempt to place the line back into service. Until new slurry transfer lines have been installed and placed into service, the 242-A Evaporator cannot slurry out concentrated waste to tank farms to allow waste volume reduction. To ensure long-term success of the evaporator, a replacement feed line will also be installed. New transfer lines are to be installed to the AW-02A Central Pump Pit. Prior to the installation of the new transfer lines, the existing jumpers and electrical support equipment at AW-02A are to be removed in order to support laser scanning of the wall and Air Lift Circulator nozzles.

14. Solution

The removal of existing equipment to support the future upgrades at AW-02A are divided into two separate electrical and mechanical change notices. This ECN captures the changes for the removal of the existing AW-02A mechanical equipment (Six existing Jumpers assemblies and the Dummy Pump Head).

15. Analysis

None required.

16. Description of Change
