  1. Radioactive MaterialsHandling and Accountability HPT 001.310

  2. Enabling Objectives • Define:BSM ControllerBSM CustodianByproduct MaterialItem Control AreaNORMPhysical InventorySource

  3. Enabling Objectives • Define:- Sealed Source- Exempt Source- Non-Exempt Source- Source Material- User- Special Nuclear Material

  4. Enabling Objectives • Identify License-Containing Document • Identify TVAN BSM Procedure • State BSM Controller Responsibilities • State BSM Custodian Responsibilities • Tell SNM Controller Responsibilities

  5. Enabling Objectives • Identify Radioactive Materials Receipt Org. • Identify Receipt Survey Time Period • Identify NRC Regulation for Exempt Quantities • Identify NRC Regulation for Distribution of Exempt Quantities • State Inventory Requirements/Procedures

  6. Enabling Objectives • Tell Actions for Lost/Stolen Sources • Identify Leak Test Requirements • State Leak Test Procedures • Calculate Leak Test Smear Activity • Identify BSM Disposal Organization

  7. Basis Documents • Code of Federal Regulations • Plant Technical Specifications--Operating License -- BSM/SNM Authorization • TVAN Procedures-- SPP-5.6, “Controlling Byproduct and Source Material”-- SPP-5.8, “Special Nuclear Material Control”

  8. BSM Controller • Individual in RADCON Responsible for BSM Source Control • Directs and Maintains Facility BSM Program • Maintains Copies of Records-- Receipt-- Transfer-- Inventory-- Leak Test-- Disposal

  9. BSM Custodian • Responsible for BSM Control Within User Group • Controls BSM Sources Assigned to Group • Provides & Maintains Storage Area for Group • Keeps Inventory & Leak Test Records Accessible

  10. SNM Custodian • Reactor Engineering Representative Responsible for Management of All SNM at the Site-- Supply/Receipt Control-- Internal Control-- Isotopic Inventories-- Shipping Control

  11. Procuring Radioactive Materials • Requests for BSM made by-- BSM Custodian-- User Groups • BSM Controller ensures:-- Materials Actually Needed-- Materials Not Available Onsite-- Adequate Controls by Custodian/User Group • RADCON/BSM Controller Approves Request • SNMC Approves Requests for Nonfuel SNM

  12. Receiving Radioactive Materials • Packages Must Meet 10CFR20.1906 Requirements • Received by Site Nuclear Stores • Inspect Packages for Leakage or Damage • RADCON Surveys Package|-- Within 3 Hours For White I, Yellow II or III • Packages Opened in Presence of RADCON

  13. Inspect Packages for Damage

  14. Receipt of Special Nuclear Materials • SNMC Opens Unsealed Packages Within Two Days of Receipt-- Conduct Piece Count to Verify Content • Verify Seals Intact With Correct Seal Numbers for Sealed Containers • Reconcile any Differences • Report Receipt to Nuclear Fuels

  15. BSM Storage Accountability & Use • Properly Label All Sources and/or Containers • Storage Locations Approved by BSM Controller • Administrative Controls-- Records Assigning Custodians-- Inventory or List of All Sources-- Records of Source Assignments

  16. Assignment of Sources • User Accountable for Control, Handling, and Return of Sources • Individual User May Not Transfer Assignment • Any Nonexempt Source Not in Its Assigned Storage Location MUST be Signed For. • Only Individuals Authorized by the Assigned BSM Custodian or Controller May Sign Out Licensed Sources

  17. Exempt Sources • Exempt Concentrations and Exempt Quantities Defined by 10 CFR 30.14 and 10 CFR 30.18 • Exempt Concentrations and Exempt Quantities Listed in 10 CFR 30.70 and 10 CFR 30.71 • Distribution of Exempt Sources Authorized by 10 CFR 32

  18. Control of SNM • SNMC Ensures RADCON Requirements Met • All Transfers of SNM Documented • Nonfuel SNM Identified on Inventory Records • ICAs Established for Physical Security • SNMC Authorizes Transfers Into, Out of, or Within an ICA • Calibration Sources Removed from ICA Must be Signed Out to Personal Custody of User

  19. BSM Source Inventory • Conducted Semiannually • Inventory All Sources Containing:-- > 100 µCi of Beta and/or Gamma-- > 5 µCi of Alpha-- Certain Sources with Exempt Quantities That Exceed 100 µCi • Verify by Direct Observation or Detection by Survey Instruments

  20. “Found” BSM Sources • Take Positive Control • Notify BSM Controller • BSM Controller Will:-- Report to RADCON Superintendent-- Report to Shift Manager-- Document the Occurrence-- Forward Report to RADCON Superintendent

  21. “Lost” BSM Sources • If Quantity Greater Than 10 Times 10CFR20, Appendix C, or 1,000 Times the Aggregate, BSM Controller will:-- Document the Occurrence-- Notify the RADCON Superintendent-- Notify the Shift Manager for Reportability Determination • For Lesser Quantities, Document & Report to RADCON Superintendent

  22. Leak Testing BSM • Leak Test All Sources Containing:-- > 100 µCi of Beta and/or Gamma-- > 5 µCi of Alpha-- Certain Sources with Exempt Quantities That Exceed 100 µCi • Stored Sources When Removed from Storage • Start-up Sources Prior to Installation • Upon Receipt, if not Performed in 6 Months • Following Repair or Maintenance on Source

  23. General Guidelines for Conducting Leak Tests • Use Dry Smears or Swabs • Wipe Encapsulated Sources Directly • Wipe Container of Plated/Mylar Window Sources • Wipe External Surfaces of Enclosed Sources • Wipe Housing Internals of Sources that move through a Housing

  24. Evaluating Leak Test Smears • Use the Equation:Activity (µCi) = Gross Counts – Bkg Counts (Detector Eff)(2.22 E6) • If Activity ≥ 0.005 µCi-- Withdraw From Use or Control Access-- Document & Report to RADCON Superintendent

  25. SNM Inventory • Conducted Annually by SNM Custodian • ICA Inventories Completed Within 30 Days From Start • Use Direct Verification Where Possible • Updating Last Inventory Acceptable • Verification of Type-E Metal Seals Integrity • Transmit Records to Management Services Within 60 Days

  26. Transfer & Disposal of RAM • BSM Returned to BSM Controller for Transfer or Disposal • Coordinate with RadWaste for Transfer • Obtain RadWaste Concurrence for Disposal • Shipments Prepared by RadWaste in Accordance with RMSM • SNM Ensures Packages Containing SNM are Prepared & Controlled per RMSM

  27. QA Records • BSM Source Receipt Records • Facility-Specific Inventory Forms • Forms for:-- Receipt-- Offsite Transfer-- Disposal • Leak Test Documentation

  28. Summary • NRC Regulations and TVAN Procedures • RADCON Responsible for BSM Control-- BSM Controller from RADCON-- BSM Custodian for User Groups • SNM Custodian for Special Nuclear Material Control • BSM Controller & Custodians Perform Inventory & Leak Tests • RadWaste Responsible for Disposal and/or Shipment
