The partial modification of the use of ANSI/ANS-8.5-1996 "borosilicate glass Raschig rings as a neutron absorbing solution fissile material Collector "(in English). This section compared with the ANSI/ANS-8.5-1996, the main differences are as follows. --- Use of national standards and industry standards to replace part of the American standard ANSI/ANS-8.5-1996 referenced; Raschig rings provisions --- water resistance should be GB/T 6582 Determination, water resistance should reach level 1; --- Density measurement should be carried out in accordance with the provisions of GB/T 5432's; --- Determination of boron content using QB/T 3572 Methods for chemical analysis. This Part replaces GB/T 15146.6-1994 "for fissile materials outside reactor - Nuclear criticality safety borosilicate glass Raschig rings and Its guidelines for the application. " Section compared with the GB/T 15146.6-1994 The main changes are as follows. --- Modification and increased the reference standard; --- Increase a few terms; --- Increase the general requirements for the Raschig rings used as a critical means of control; --- Added a limit for the uranium-233 content. Appendix A of this section is an informative annex. This part is proposed by the China National Nuclear Corporation.
