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”

http://www.tva.gov/



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

http://www.tva.gov/



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

http://www.tva.gov/



SNM Custodian

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

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

http://www.tva.gov/



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

http://www.tva.gov/



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

http://www.tva.gov/



Inspect Packages for Damage

http://www.tva.gov/



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

http://www.tva.gov/



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

http://www.tva.gov/



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

http://www.tva.gov/



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

http://www.tva.gov/



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

http://www.tva.gov/



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

http://www.tva.gov/



“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

http://www.tva.gov/



“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

http://www.tva.gov/



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

http://www.tva.gov/



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

http://www.tva.gov/



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

http://www.tva.gov/



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

http://www.tva.gov/



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

http://www.tva.gov/
