Explanatory Notes

Using this form	Submit a separate ASO311 for each material category held, and for each Material Balance Area applicable to the permit holder. Use as many ASO311 forms as necessary to list all transactions for this period. Permit holders who possess nuclear material within a facility (as defined in the Safeguards Act) must submit the form for every calendar month in which a transaction occurs, otherwise annually.
Ref. No.	A sequential reference number is required for each form of this type submitted by the Permit Holder (eg, 001, 002, 003, etc). Where amendments are made to a previously submitted form, please use the same reference with a sequential revision number (eg, 003-Rev.1).
Material Balance Area	As defined in your permit.
REPORTING PERIOD Start date/End date	The ‘Start date’ must be the next calendar day after the ‘End date’ of the previous Reporting Period. If this is an annual report, the ‘End date’ is 30 June for the current year, and must be submitted within 5 working days thereafter.
Units of measure	The unit of measurement shall be as follows: Material Category Unit Precision (N)atural and (D)epleted uranium, (T)horium, Heavy (W)ater, and (G)raphite Kilograms (kg) ≥0.01 kg - two decimal places. If <0.01 kg - as precise as known (E)nriched uranium and (P)lutonium Grams (g) ≥0.01 g - two decimal places. If <0.01 g - as precise as known
Opening balance	These values must be the same as the ‘Closing balance’ from the previous ASO311 for the same material category.
Closing balance	If this a final report for the annual reporting period, the values entered must be those resulting from a physical inventory taking, and where any differences arise between the ‘Closing balance’ and the values in the preceding line (as the ‘Running balance’), these must be explained in a separate statement forwarded to ASNO.
Signature and permit details	This form must be signed by a representative of the Permit Holder (ie, the organisation) who will take responsibility for, and sign documents on behalf of, the organisation.
This form replaces the following forms	ASO311 (Version 4 issued 22 December 2005)
