NB/T 20008.24-2015Other material for pressurized water reactor nuclear power plants - Part 24: GH4145 alloy bars for reactor vessel internals (English PDF)

NB/T 20008.24-2015 is the English-translated version of 压水堆核电厂用其他材料 第24部分：堆内构件用GH4145合金棒.

NB/T 20008.24-2015 is the part of the Chinese energy industry series on other materials for pressurized water reactor nuclear power plants that covers GH4145 alloy bar.

It lays down the manufacturing, inspection and acceptance requirements for that nickel-base alloy bar. Its scope is the GH4145 bar supplied for the reactor vessel internals, and it is classified with the wrought nickel alloy products of the series rather than with the plant systems.

The requirements draw on quoted documents including GB/T 223, GB/T 228.1-2010, GB/T 231.1, GB/T 6394, GB/T 14999.2, GB/T 20123, NB/T 20004-2014, NB/T 20328.2-2015 and NB/T 20328.4-2015.

It stands beside Part 25 of the same series, which handles the GH4169 wire used for the springs of those internals. Issued on 1 July 2015, it has applied since 1 December 2015.
