Demolition of C-340 Metals Plant

  • Completed demolition of C-340 complex, known as the Metals Plant

  • Encompassed about 1.5 million cubic feet, the volume of a football field roughly three stories tall

  • Demolition of a single-story section was completed in mid-December, followed by removal of a four-story section. A seven-story, 120-foot-high section– the tallest building at the site–was the last to be taken down and that was completed in March 2013

Demolition of C-340 Metals Plant

  • Shipped C-340 waste to EnergySolutionsin Clive, UT

    • 1,920 tons of steel I-beams, steel plates, piping, ductwork, and equipment

    • Last shipment arrived Aug. 8 at Clive

Investigative Sampling - SMWU 4

  • The SWMU 4 investigation is being conducted in 5 phases. Phases 1 -3 were executed in FY 2013; Phases 4 and 5 are scheduled for FY 2014

  • Approximately 160 soil samples will be collected and analyzed for VOCs, SVOAs, PCBs, metals, and radionuclides

Passive gas analyzers collect sample data at SWMU 4

  • Approximately 140 groundwater samples will be collected and, except for a small subset, will be analyzed for VOAs and Tc-99. The exception is a group of 5 groundwater samples that will be part of a broader analysis (i.e., VOAs , SVOAs, PCBs, metals, and radionuclides).

Source Removal – C-400

  • In 2005, DOE signed a Record of Decision for removal of TCE contamination near Building C-400

  • Will permanently reduce the concentrations of TCE and other organic chemical compounds in soils at the main source of TCE contamination.

  • Using direct heating technology that heats soil to a level where contaminants and water are turned from a liquid into a gas, brought to the surface and destroyed

  • Treatability Study showed direct heating 98% effective

  • Remedial Action work began in late 2006, with Phase IIB starting in FY13

Groundwater plume for TCE

Investigative Sampling - Southwest Plume

  • 3 TCE source areas investigated

  • Sampled 83 soil borings during 2012 and 2013 using a direct push sample rig

  • Continuous core to 60-65-ft depths

  • Field scanned each 5-ft interval  with PID and sampled interval of highest VOC level  

  • Collected 1,095 soil samples (depth-scheduled and QC samples) for fixed base lab analysis of TCE and four other VOCs

  • Same day courier delivery to lab

  • Next-day preliminary results (Friday’s sample results available on Monday)

  • Optimized contingency sample locations based on timely results

Samples from the Southwest plume are examined

Samples are extracted from Southwest plume

Changes at Paducah

  • USEC ceased uranium enrichment operations in May 2013.

  • USEC submitted notice of intent to return the leased property back to DOE in August 2013.

  • DOE is planning for the transition and in negotiations with USEC on conditions and time of turnover.

  • See http://www.emcbc.doe.gov/pgdp%20deactivation for the Request for Task Proposal (RTP) for deactivation activities at the Paducah Gaseous Diffusion Plant
