The Radioactive Liquid Waste Treatment Facility (RLWTF) truck loading station located on the northwest exterior of Hot Fuel Examination Facility (HFEF) is no longer used. The vent and pump discharge piping (two lines) penetrate the foundation wall approximately three feet below grade in a pit. During inclement weather, water pools in the pit and then drains into the Retention Tank Room (room 020) located on the Service Floor level of HFEF, which is a radiologically-controlled area. To prevent the influx of water into the room, the piping and exterior enclosure need to be removed, the penetrations and foundation waterproofed and the pit filled-in.
