NB/T 20008.1-2012Other Material for Pressurized Water Reactor Nuclear Power Plants - Part 1: Alloy Steel Forgings for Use in Reactor Coolant System Supports (English PDF)

NB/T 20008.1-2012 is the English-translated version of 压水堆核电厂用其他材料 第1部分：反应堆冷却剂系统支承件用合金钢锻件.

Part 1 of the Chinese energy industry series on other materials for pressurized water reactor nuclear power plants, NB/T 20008.1-2012 deals with alloy steel forgings used in reactor coolant system supports.

It fixes the technical requirements for their manufacture, chemical composition and mechanical properties, together with the testing and inspection that verify them.

The forgings concerned are those for steam generator and reactor coolant pump dampers, for reactor pressure vessel support bearings and for the U-shaped inserts of the coolant pump supports.

Classified H43 in China and 77.140.85 internationally, it groups with alloy steel forgings for nuclear service. Analysis and mechanical testing follow GB/T 223.5, GB/T 228.1-2010, GB/T 229-2007, GB/T 231.1, GB/T 4336 and GB/T 20066. Issued on 6 January 2012, it has applied since 6 April 2012.
