Radioactive air emissions notice of construction debris removal 105-KE basin
The 105-KE Basin contains 1,150 Metric Tonnes of Uranium (MTU) of N Reactor fuel, along with less than half a MTU of single pass reactor (SPR) fuel. In addition to the spent nuclear fuel (SNF) in the 105-KE Basin, extensive quantities of debris and a substantial amount of sludge have accumulated in the basin. The 105-KE Basin fuel and sludge are not encapsulated and, as a result, corroding fuel has produced contamination products that are deposited on the basin walls, floor, and equipment. contamination products produce radiation dose exposures to the workers. To decrease worker exposures, this Notice of Construction (NOC) describes dose reduction modifications under consideration to mitigate worker radiation exposure from the basin walls and exposed piping. The major equipment egress paths from the basin (the dummy elevator pit and the south loadout pit) are blocked completely with debris and/or empty canisters. Therefore in addition to dose reduction, this NOC also describes debris removal activities and equipment. Recently, the primary water treatment system has been without mechanical filtration capabilities. This NOC describes planned modifications to the primary water treatment system to restore mechanical filtration by restarting the cartridge filters. The proposed modifications described in this NOC are expected to commence in the Fall of 1995. Finally, the NOC describes two other basin activities, fuel and sludge movement, that are expected to be routine in the future.
