ASTM C1334-05(2016)e1

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.

Designation: C1334 − 05 (Reapproved 2010) C1334 − 05 (Reapproved 2016)
Standard Specification for
Uranium Oxides with a U Content of Less Than 5 % for
Dissolution Prior to Conversion to Nuclear-Grade Uranium
Dioxide
This standard is issued under the fixed designation C1334; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (´) indicates an editorial change since the last revision or reapproval.
ε NOTE—Editorially updated organization name of referenced document in 2.2 in January 2016.
1. Scope
1.1 This specification covers uranium oxides, including processed byproducts or scrap material (powder, pellets, or pieces), that
are intended for dissolution into uranyl nitrate solution meeting the requirements of Specification C788 prior to conversion into
nuclear grade UO powder with a U content of less than 5 %. This specification defines the impurity and uranium isotope limits
for such urania powders that are to be dissolved prior to processing to nuclear grade UO as defined in Specification C753.
1.2 This specification provides the nuclear industry with a general standard for such uranium oxide powders. It recognizes the
diversity of conversion processes and the processes to which such powders are subsequently to be subjected (for instance, by
solvent extraction). It is therefore anticipated that it may be necessary to include supplementary specification limits by agreement
between the buyer and seller.
1.3 The scope of this specification does not comprehensively cover all provisions for preventing criticality accidents, for health
and safety, or for shipping. Observance of this specification does not relieve the user of the obligation to conform to all
international, national, state and local regulations for processing, shipping, or any other way of using urania powders (see 2.2 and
2.3).

3. Terminology
3.1 Definitions of Terms Specific to This Standard:
3.1.1 Terms shall be defined in accordance with Terminology C859, except for the following:
3.1.2 Commercial Grade Uranium Oxide, n—any oxide of uranium made from unirradiated uranium. It is recognized some
contamination with reprocessed uranium may occur during routine processing; this is acceptable provided that the specification for
Commercial Grade Uranium Oxide as set forth in 4.1 is met.
3.1.3 scrap, n—in the nuclear industry, residues that contain sufficient quantities of source or special nuclear material to be
worthy of recovery.
4. Isotopic Content
4.1 For Commercial Grade Uranium Oxide with an isotopic content of U between that of natural uranium and 5 %, the
isotopic and radionuclide limits of Specification C996 shall apply. The specific isotopic and radionuclide measurements required
by Specification C996 may be waived, provided that the seller can demonstrate compliance through, for instance, the seller’s
quality assurance records.
4.2 For commercial uranium oxides not having an assay in the range set forth in 4.1, the isotopic requirements shall be as agreed
upon between the buyer and seller.
5. Physical and Chemical Requirements
5.1 Uranium Content—The uranium content shall be determined using methods described in Test Methods C696 and C799, or
as agreed upon between the buyer and seller. Based on the oxygen-to-uranium ratio, the minimum total uranium content shall also
be agreed upon between the buyer and seller.
5.2 Impurity Content—The impurity content shall not exceed the individual element limits specified in Table 1. The summation
of the contribution of each of the impurity elements listed in Table 1 shall not exceed 1000 μg/gU. The impurity content shall be
determined using methods described in Test Methods C696 or as agreed upon between the buyer and seller. If the Table 1
specifications are not met, and processing beyond simple dissolution is anticipated, the concentrations of carbon and toxic elements
such as Ag, Cr, Pb, Hg, Se, Sb, and As shall be reported for information. Analysis requirements may be waived provided the seller
can characterize the material, for example, through the seller’s QA records.
5.3 Equivalent Boron Content—The total equivalent boron content (EBC) shall not exceed 2.0 μg/gU. The list of elements to
be considered in the EBC calculation shall be as recommended in Practice C1233. The method of performi
