Foreword

This revised standard adopts ASTMC753.2004 "nuclear grade sinterable uranium dioxide powder standards" (in English). This standard is based on ASTMC753.2004 redrafted listed in Appendix A of this standard and ASTM standard number reg reg Control list numbered. Taking into account the actual situation in China, this standard when using ASTM standard has been modified. The technical differences between a single vertical line identification They are involved in terms of margin. In Appendix B gives a list of the technical differences and the reasons for the reference. This standard replaces GB/T 10265-1998 "nuclear grade sinterable uranium dioxide powder conditions." This standard compared with GB/T 10265-1998, the main changes are as follows. a) "Scope" content as part of the modification (see Chapter 1); b) changes in standard references (see Chapter 2); c) oxygen ratio uranium from "2.05 to 2.18" to "2.02 - 2.18" (see 3.1.2); d) "core requirements" to merge "Chemistry Requirements" and adds, "cleanliness" in the "chemistry requirements" (1998 version 3.2 and 3.1; this Version 3.1); e) "Table 2 equivalents of boron content factor" section to modify (the 1998 edition 3.2.2; 3.1.6 edition); f) "particle size" in the "0.40mm" to "425μm" (1998 edition 3.3.1; 3.2.1 edition); g) "powder batch requirements" in the "batch definition" content modification (see Chapter 5); h) "sampling" full content modification (see 6.1); i) increase the "documents" (see Chapter 7); j) "packaging, labeling, transportation and storage" as a partial modification of the content (1998 edition, Chapter 7; edition Chapter 8); k) to sinter test adds visual inspection, and part was modified (see Appendix C); l) the increase of the standard terms and ASTMC753.2004 standard terms of control list (see Appendix A); m) the increase of the standard and ASTMC753.2004 standard list of technical differences and the reasons (see Appendix B). This standard Annex A, Annex B, Annex C is informative appendices. The standard proposed by China National Nuclear Corporation. This standard by the National Standardization Technical Committee of nuclear energy. This standard was drafted. China Jianzhong Nuclear Fuel Limited. The main drafters of this standard. Wu Yun, Wang Bangwu, Yang Xiaodong Peng Castle. This standard replaces the standards previously issued as follows. --- GB/T 10265-1988, GB/T 10265-1998. Nuclear grade sinterable uranium dioxide powder conditions

1 Scope

3 Technical requirements

3.1 Chemical requirements 3.1.1 uranium content Minimum uranium content was 87.0% (mass fraction, dry basis). 3.1.2 Oxygen to Uranium (O/U) Uranium dioxide powder Oxygen to Uranium (O/U) is generally controlled at 2.02 ~ 2.18. 3.1.3 Elements and impurity content limits Based on the quality of individual uranium impurity element content should not exceed the limits specified in Table 1, the sum of impurity elements listed in Table 1 should not exceed Over 1500μg/gU. If a single element analysis results below the minimum limit of analytical methods can detect, it is added to their total minimum limits miscellaneous Matter content in. 3.1.4 moisture content Moisture content should not exceed the uranium dioxide powder 0.4% by mass. 3.1.5 isotopic content Should be measured 234U, 235U, 236U content mass fraction reported results. 235U isotopic enrichment of less than 5% of the uranium dioxide powder According to GB/T 13696-2007 4.1 execution, more than 5% enriched by the buyer and the seller agreed.
