• Identify BSM Disposal Organization

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”

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

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

SNM Custodian

• Reactor Engineering Representative Responsible for Management of All SNM at the Site

-- Supply/Receipt Control-- Internal Control-- Isotopic Inventories-- Shipping Control

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

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

Inspect Packages for Damage

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

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

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

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

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

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

“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

“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

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

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

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

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

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

QA Records

• BSM Source Receipt Records

• Facility-Specific Inventory Forms

• Forms for:-- Receipt-- Offsite Transfer-- Disposal

• Leak Test Documentation

Summary• NRC Regulations and TVAN Procedures• RADCON Responsible for BSM Control

-- BSM Controller from RADCON-- BSM Custodian for User Groups
