Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009. This standard replaces GB/T 13375-2008 "Natural uranium hexafluoride technical conditions." This standard and GB/T 13375-2008 compared to the main technical changes are as follows. --- The scope of the "quality assurance" be amended to "quality certificate"; "This standard applies to enrichment plant for the supply of natural hexafluoride Uranium products. "Revised as" This standard applies to natural products of uranium hexafluoride. "; --- Added the term "total absolute vapor pressure" (see 3.2); --- Total increase of 100 ℃ absolute vapor pressure of 624kPa (see 3.2); --- Modify "Total liquid absolute pressure limit" in Table 1 to "Total absolute vapor pressure limit of liquid natural uranium hexafluoride"; --- Revised Table 2, "Total Absolute Solid Pressure Limit" to "Total Absolute Pressure Limit of Solid Uranium Hexafluoride in Solid State"; --- The original standard 4.4.1 "at a temperature of 300 ℃, the vapor pressure of not more than 101.3kPa non-volatile fluoride, the following impurity element The total amount of prime should not exceed 300μg/gU. "Revised as" at a temperature of 300 ℃, the vapor pressure is not greater than 101.3kPa, the formation of non The total amount of the following impurity elements of volatile fluoride should not exceed 300 μg/gU. "(See 4.3.1); --- The original standard 4.4.2 "The following impurity element content" was revised to "the following volatile impurity element content"; --- The original standard 5.2.1 in "liquefied containers at a temperature of 93 ℃ ± 3 ℃ conditions, with EJ/T 303 provisions of the 2S sampler or with Need to be mutually agreed on the sampling container for liquefaction sampling. "Amend to read" Fully liquefied UF6 using a liquefied sampling device And EJ/T 303 provisions of the 2S sampler or supply and demand sides agreed sampler for liquefaction sampling. "; --- The original standard 6.1 "in accordance with the provisions of the method of EJ/T 895." Revised as "the use of uranium hexafluoride liquefaction sub-sampling device, according to EJ/T 895 the provisions of the method. "; --- The original standard 6.3 "at the specified temperature, with a precision of not less than 1.5 gauge pressure gauge measuring the pressure inside the container." To "in the provisions of Temperature, the use of precision of not less than 1.5 gauge pressure vessel containing uranium hexafluoride measurement of absolute pressure. When necessary (for example. System maintenance, the system pressure instability) Sampling through the sampling system, the system can be used uranium hexafluoride impurity saturation vapor pressure measurement system Set the device and method to measure the total absolute vapor pressure of the vessel. "; --- Test method to increase the determination of chlorine with reference to Appendix B; --- The original standard 7.2 and 7.3 content is combined into "7.2 transport, storage in accordance with the provisions of EJ/T 307 and GB 11806 begging. "; --- Added Appendix A "Determination of natural uranium hexafluoride tungsten, chromium, molybdenum, vanadium, titanium, arsenic ICP-AES method"; --- Added Appendix B "Determination of natural chlorine hexafluoride hydrolyzate chloride silver salt spectrophotometry." This standard proposed by China National Nuclear Corporation. This standard by the National Nuclear Standardization Technical Committee (SAC/TC58) centralized. This standard was drafted in. Nuclear four four four limited company. The main drafters of this standard.Li Lu, Wang Shumin, Zhang Huizhong, Ru Faquan, Wei Gang, Zhou Shoufu, Yan Huimin, Hu Shengjun. This standard replaces the standards previously issued as. --- GB/T 13375-1992, GB/T 13375-1999, GB/T 13375-2008.
