Scope
GB 15146.10-2001 is the English-translated version of 反应堆外易裂变材料的核临界安全 固定中子吸收体的应用安全要求.
This part of GB 15146 covers the fixed neutron absorbers — borated plate, boron carbide, cadmium and similar materials built permanently into racks, tanks and transport packages — that are relied upon to keep a configuration subcritical. Because the safety case depends on the absorber still being there and still working decades later, the standard sets the general safety considerations, the design requirements, the safety evaluation, and the verification and inspection needed to confirm the absorber's presence, position and areal density over the life of the installation. Issued on 24 October 2001, in force since 1 April 2002; first edition. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the edition it replaces are taken from there. The clause text, the tables and the numeric limits are not reproduced on this page — they are in the document itself, which is delivered in full in English translation.
