Connecticut Yankee Atomic Power Company

NRC Region 1 Briefing Tuesday, August 31, 2004, King of Prussia, PA Connecticut Yankee Decommissioning Project Status Overall Started decommissioning self performance in June 2003 RPV disposed in Barnwell January 2004 Physical work scheduled to be completed fall 2006 License termination scheduled for summer 2007 via partial site releases Project performing consistent with overall self-performance cost and schedule 2 GTCC and 13 Fuel canisters in storage at ISFSI Self-performance work 36.50% complete (vs. forecast of 29.13%) as of July 31 T& M Headcount: Approx. 730 workers (near project peak)

Addressing non-compliance and supervisory oversight concerns Industrial Safety 4.0 Million Hours since last LTA - More than 4 years Six OSHA Recordables in 2004 (1.24.x/200,000 work hours as of 8/30) - including 3 in August Track first aid cases as leading indicators - a mixture of causes including bee stings, cut, and bruises Radiation Protection 2004 dose to date/ALARA estimate for work complete x 100 = 75% (8/14)

Year to date (8/14) actual exposure 55.96 PersonREM Project to date (as of 8/14) 731 PersonREM Currently anticipating completing decommissioning and fuel load with a dose of 830 PersonREM versus PSDAR estimate of 935 Expecting 01 investigation on the High Rad. valve incident with MBI in July - CY Root Cause completed and provided to John Wray - Did not substantiate "willful" violation

Higher dose due to extended time, higher heat rate and dose from vacuum drying skid Addressing heavy haul trailer issues Addressing spent fuel pool chemistry challenges

  • Installed in-pool water box or cofferdam
  • Additional in-pool demineralizers being installed Water discovered in the bottom of empty VCCs:
  • Removing water from VCC prior to loading
  • Considering weep-hole installation for those already on the pad Decommissioning/ Building Removal Preparations Containment
  • All reactor cooling system piping removed
  • Cutting out Neutron Shield Tank: half of about 172 pieces to be cut this week

Buildings demolished

  • Old HP facility
  • Primary ventilation stack

Demolition underway

  • Turbine hall
  • Waste disposal building Waste Management 19.5 million lbs of waste shipped as of 7/31-7% of 266 million lbs of waste (excluding large components and trash) to be shipped Contracts with Envirocare, RACE and Permafix for D+D wastes Need US Ecology in Idaho as disposal option for PCB contaminated low level radioactive waste (NRC approval req'd)

Clean concrete being disposed in Connecticut License Termination Groundwater source term removal

  • Ground water level in vicinity of contaminated soil reduced with de-watering wells
  • Strontium level trending down - Please see attached graphs
  • Structure and contaminated soil removal continues
  • Conducting bed rock FSS test
  • Contaminated soil excavation to be completed this fall
  • Backfill with clean soil winter 2005
  • Spring 2005: De-watering wells turned off, ground water levels return to normal, 18 month monitoring begins LTP
  • Met with NRC on August 17 to discuss amendment (activated concrete/leach rate of H3)
  • Biennial LTP update scheduled to be submitted to NRC on September 2
  • Good support from Region 1 and ORISE on FSS Expecting DEP response on site closure under RSRs in September (RCRA IAW QAPP, Rad. IAW RSR's at 1 9mR and GW IAW RSR's at EPA's MCL's)

Submitted State closure plan (LTP) in August Continuing RCRA RFI, sediment/soil sample (22 AOCs require closure)

Submitted proposed tech spec change to deal with elimination of control room after fuel transfer Awaiting NRC response on Phase 1 area (non-impacted) license termination request NRC Region 1 provides effective regulatory status information at CDAC meetings Efforts to address Drocedure noncompliance issues Issues identified in low-threshold condition report program

Each CR addressed by management review team (perceived non-compliances require MRT review w/in 3 days for immediate CA)

Work stopped to address two condition reports involving work in Locked High Radiation and Radiation Area - Contractor not allowed to return to work until major causal issues addressed Conducting assessments by outside experts of FSS, Licensing, Engineering, and Radiation Protection and QPD heightened attention to CR closures and development of Work Instructions Improving quality of work instructions in work orders and ensuring that they are available and clear for field personnel Clarifying safety expectations in new safety manual Reinforced expectations with site supervisors and workers in several meetings - Key message:

safety and procedure compliance are not to be compromised to meet schedule Expect managers and supervisors to spend time in field observing and supporting work Improvement with infield supervision by new labor contractor - S&W/Shaw Rolled out new disciplinary action program for all on site workers Accountability at the management level for departmental performance relative to non-conformances and corrective action
