INSTRUCTIONS TO NRC AND AGREEMENT STATE LICENSEES FOR REPORTING HIGH-RISK SEALED SOURCE TRANSACTIONS 

The completed form is considered to be Official Use Only – Security Related Information; it is not considered to be Safeguards Information. 

Use an addendum sheet for reporting additional sources.

Note to Licensees: This form may be used to report source transactions in lieu of 

using the NSTS online application. Sections 1-4 on Page 1 of the form are required 

for all source transaction types. Sections 5-12 should only be populated for the 

associated Transaction Type (3B) selected. For example, when reporting a Source 

Transfer and a Source Export, Sections 6 and 11 should be populated. Multiple 

Transaction Types may be selected if they occur on the same Transaction Date, and 

should be reported on NRC Form 748. Licensees reporting only one transaction type 

may use the condensed form for the Transaction Type. For example, when reporting 

a Source Receipt, NRC Form 748c should be used. 

1. Licensee Information – Enter the name, license number, and street address of 

the licensed facility. 

2. Transaction Date – Enter the date the transaction occurred, which would be the date 

of the transfer, receipt, manufacture, etc. 

3. Transaction Information and Transaction Type – Indicate if this is a new transaction

or a correction. For corrections, select the date of the previously submitted 

transaction that the correction should be associated with. Select the Transaction 

Type. Report Source should only be used for initial inventory submissions, or to 

report a source excluded from the initial inventory submission. Dispose Source 

should only be used by a Disposal Licensee. If you are sending your source back to 

the manufacturer, or sending it to a disposal facility, the transaction should be 

recorded as a Transfer. Multiple Transaction Types may be selected if they occur on 

the same Transaction Date. 

4. Preparer Information – An email address is required for a confirmation. For

regulatory purposes, your source transaction report is not considered complete 

without a confirmation from the NSTS Help Desk that the transaction report has 

been received. 

5. Source Inventory Data – This section should only be used for initial inventory 

submissions. The Make, Model, and Serial Number refer to the Source, not the 

Device. All fields are required in Section 5 EXCEPT G. Comments. If the licensee is 

reporting multiple sources on the Source Inventory transaction at the same Source 

Location Address, the location address information may be populated once, and 

referenced in the Comments block for the additional sources. 

6. Source Transfer Data – For Transfer transaction reports, all fields in Section 6 are 

required EXCEPT M. Waste Manifest Number, N. Container ID, and P. Comments. If 

the licensee is reporting multiple sources on the Transfer transaction to the same 

Receiving Licensee, the receiving licensee information may be populated once, and 

referenced in the Comments block for the additional sources. 

7. Source Receipt Data – For Receipt transaction reports, all fields in Section 7 are 

required EXCEPT M. Waste Manifest Number, N. Container ID, and T. Comments. If 

the licensee is reporting multiple sources on the Receipt transaction at the same 

Source Location Address, the location address information may be populated once, 

and referenced in the Comments block for the additional sources. 

8. Source Disposal Data – For Disposal transaction reports, all fields in Section 8 are 

required EXCEPT J. Comments. If the licensee is reporting multiple sources on the 

Disposal transaction at the same Source Disposal Address, the source disposal 

address information may be populated once, and referenced in the Comments block 

for the additional sources. 

9. New Manufactured Source Data – For New Manufactured Source transaction 

reports, all fields in Section 9 are required EXCEPT F. Comments. If the licensee is 

reporting multiple sources on the Manufacturer transaction at the same Source 

Location Address, the location address information may be populated once, and 

referenced in the Comments block for the additional sources. 

10. Source Import Data – For Import Source transaction reports, all fields are required 

EXCEPT L. Comments. If the licensee is reporting multiple sources on the Import 

transaction at the same Source Location Address, the location address information 

may be populated once, and referenced in the Comments block for the additional 

sources. 

11. Source Export Data – For Export Source transaction reports, all fields are required 

EXCEPT M. Comments. If the licensee is reporting multiple sources on the Export 

transaction to the same Foreign Company/Foreign Address, the information in cells 

A-E may be populated once, and referenced in the Comments block for the 

additional sources. 

12. Source Disassemble Data – For Disassemble Source transaction reports, all fields 

are required EXCEPT H. Comments. If the licensee is reporting multiple sources on 

the Disassemble transaction at the same Source Location Address, the location 

address information may be populated once, and referenced in the Comments block 

for the additional sources.
