  1. Bulk Survey for Release (BSFR) Program Roger Fenner Department of Environment and Conservation Division of Radiological Health Presentation to Solid Waste Advisory Committee July 5, 2007

  2. Main Objective Is The BSFR Protective of Human Health and the Environment?

  3. SWAC • Terminology • BSFR • Tennessee Department Of Environment And Conservation Approval Process For BSFR Programs • Radiation In Our Lives • Conclusion/Comments

  4. TERMINOLOGY rem A Measurement Of The Biological Effective Dose Risk Of Suffering From Health Effects Following Exposure to Radiation.

  5. TERMINOLOGY A rem Is A Relative Large Number For The Amounts And Types Of Radiation Exposures We Will Be Discussing, Therefore We Need To Define Two Other Terms To More Appropriately Fit Our Purposes For This Meeting.

  6. TERMINOLOGY The millirem (mrem) Is 1/1000th Of A rem. For Our Purposes It Is Easier to Remember That: 1000 mremAre Equal To1 rem

  7. TERMINOLOGY The Second Term Is The microrem (rem) A microrem (rem) Is 1/1000th Of A mrem For Our Purposes It Is Easier To Remember That: 1000 rem Are Equal To 1mrem

  8. TERMINOLOGY 1000rem= 1 mrem

  9. TERMINOLOGY WARNING Do Not Let Yourself Be Confused If We Are Talking About Exposure Rates. 1 mrem/hr Is Still Equal To 1000 rem/hr AND 1 mrem/yr Is Still Equal To 1000 rem/yr

  10. TERMINOLOGY The Last Term I Want to Introduce Is The Term Used To Discuss How Much Radioactivity Is in Any Type of Material Including BSFR Material. It Is The Term For What We Refer To As Activity. picoCurie (pCi)

  11. TERMINOLOGY 1 picoCurie Is Equal To 0.037 Radioactive Decays (Disintegrations) Every Second.

  12. TERMINOLOGY For Our Purposes We Are Concerned With How Many Decays Per Second Are Associated With Each Gram Of Material. So We Will Talk About picoCuries per gram (pCi/g)

  13. TERMINOLOGY Three Terms To Remember mrem rem pCi/g

  14. BSFR What Is BULK SURVEY FOR RELEASE?

  15. BSFR BSFR Is A Term Used to Refer To A Licensed Process That Has Been Approved By The Tennessee Department Of Environment And Conservation (TDEC) To Allow The Disposal Of Materials With EXTREMELY LOW LEVELS OF RADIOACTIVE MATERIAL In Class I Landfills

  16. BSFR Example Of BSFR Materials • Soils • Resins • Concrete • Wood • Asphalt • Paper, Plastic, Clothing

  17. BSFR State Regulations For Protection Against Radiation (SRPAR) Rule 1200-2-5-.121

  18. BSFR METHOD FOR GRANTING APPROVAL OF ALTERNATIVE DISPOSAL PROCEDURES

  19. BSFR This Regulatory Authority Is The Same As Provided For In NUCLEAR REGULATORY COMMISSION (NRC) TITLE 10 CFR 20.2002

  20. BSFR Applications Are Reviewed And Evaluated Based On 5 Criteria As Per This Regulation.

  21. BSFR 1. The Description Of The Waste To Be Disposed, Including The Physical And Chemical Properties. 2. Manner And Conditions Of Waste Disposal.

  22. BSFR 3. Analysis And Evaluation Of Pertinent Information About The Environment Of The Disposal Site.

  23. BSFR 4. Analysis And Procedures To Ensure That Doses Are Maintained As Low As Reasonably Achievable (ALARA) And Within The Dose Limits In SRPAR.

  24. BSFR 5. The Nature And Location Of Other Potentially Affected Licensed And Unlicensed Facilities.

  25. BSFR How Does BSFR Work?

  26. BSFR 1. Material Is Analyzed At Each Generator’s Site For The Chemical Constituencies And To Identify Each Radionuclide And Its Activity (pCi/g). 2. The Material Is Then Shipped According To U.S. Department Of Transportation (USDOT) Regulations To A Processor.

  27. BSFR 3. At The Processor Each Package Is Analyzed Again To Verify The Radionuclides And Their Associated Activities (pCi/g). 4. This Analysis Allows The Processor To Determine If The Material Meets The Predetermined Limits Authorized In Their Radioactive Material License For BSFR Disposal.

  28. BSFR 5. If The Material Meets The Predetermined Licensed Authorized Limits And The Container Surface Dose Rate Limits And Does Not Meet The USDOT Definition For Radioactive Material It Is Then Shipped To The Preauthorized Landfill.

  29. BSFR 6. At the Landfill The Material Goes Through A Final Check. Only After It Passes The Final Check Is It Disposed In The Landfill.

  30. BSFR How Does TDEC Evaluate A Request For Alternative Disposal?

  31. BSFR The Request Is Analyzed By The Licensing Staff The Same As Any Other Application. Which Includes: Qualification Of Management and Health Physics Personnel Adequacy Of Their Radiation Safety Program (Procedures, Instrumentation, Facility, Training, Etc.)

  32. COMPUTER MODEL RESRADIs A Computer Program Used To Evaluate The Potential Doses From Radioactive Material In The Ground

  33. COMPUTER MODEL Has Undergone Extensive • Review • Benchmarking • Verification And • Validation

  34. COMPUTER MODEL USERS OF THE MODEL • U.S. Nuclear Regulatory Commission (NRC) • U.S. Environmental Protection Agency (USEPA) • U.S. Department Of Energy (USDOE) • DOE Contractors

  35. COMPUTER MODEL • U.S. Army Corps Of Engineers (USACE) • Industrial Firms • Universities • Foreign Government Agencies And Institutions (France, Spain, Germany, Russia, Taiwan, Belgium, Croatia, Malaysia, Czech Republic, Canada, and Japan)

  36. COMPUTER MODEL What Does The Computer Model Take Into Consideration? RESIDENT FARMER SCENARIO

  37. COMPUTER MODEL

  38. COMPUTER MODEL

  39. COMPUTER MODEL Additional Safety Factors Added By TDEC

  40. COMPUTER MODEL 1. 1mrem/yr TDEC Limit VS 25mrem/yr NRC Limit

  41. COMPUTER MODEL 2. TDEC Models The Landfill As Containing Uniformly Distributed BSFR Material Producing A 1 mrem/yr Dose.

  42. COMPUTER MODEL

  43. COMPUTER MODEL 3. TDEC Has Limited Disposal Of Materials At BFI Middle Point To No More Than 5% Of The Total Waste Received.

  44. COMPUTER MODEL 4. TDEC Models For No Clean Cover Soil Placed Between The Resident Farmer And The Waste

  45. COMPUTER MODEL

  46. COMPUTER MODEL 5. For The Unsaturated Zone Area We Only Give Credit For The Clay Liner And The Soil Buffer. (No Credit Is Given For The Plastic Liner.)

  47. COMPUTER MODEL 6.Assume All Waste Is Present At The Concentration Limit On The Day The Site Is Closed.

  48. COMPUTER MODEL These Additional Safety Factors Decrease The 1 mrem/yr Designed Dose Limit For Middle PointSignificantly

  49. RADIATION IN LIFE

  50. RADIATION IN LIFE Legislated Radiation Dose Limits For TDEC, NRC, AND ALL AGREEMENT STATES
