Explanatory Notes

Using this form	Use as many ASO323 forms as is necessary to provide a complete list all materials held.
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 Description	Include, where applicable, unique identifiers such as serial numbers.
Material category, and Units of measure	For each line entry, use one of the following letters in brackets corresponding to the material listed, and to the precision indicated. Material Category Unit Minimum Requirements (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
Chemical formula	Complete if known. Many jars of uranium and thorium compounds have the chemical formula written on the label.
Gross weight	Total weight of the jar and contents.
Compound and element weights	For small jars of chemicals, the compound weights can be estimated from the apparent volume in the jar. In the “worked example” below, a 100 gram jar of uranyl acetate (as listed on the label) is estimated to be three quarters full – hence 75 g, which translates to 0.075 kg. For the element weight, and again using the “worked example” below, uranyl acetate is 56.1% uranium (compare with chemical formula) – 75 g × 0.561 = 42.08g, which translates to 0.04 kg. For heavy water and graphite, record the material weight in the ‘Compound’ weight column.
Mat’l acquisition details	Where available. It is important for ASNO to know the origin of the listed items to ensure they are not being double-counted in ASNO’s records.
Signature/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	ASO323 issued as version 1 on 22 December 2005.
