NB/T 20244-2013Plugging Guideline for Heat Transfer Tube of PWR Steam Generator (English PDF)

NB/T 20244-2013 is the English-translated version of 压水堆核电厂蒸汽发生器传热管堵管导则.

NB/T 20244-2013 is the Chinese energy industry standard that gives guidance on plugging the heat transfer tubes of pressurized water reactor steam generators. Tubes found to be degraded are taken out of service by plugging, and this recommended standard is the reference for how that decision and that work are handled.

It is placed under Chinese classification F69 and the international class 27.120.99, within the nuclear power group of the series. NB/T 20241-2013 is listed as the document it is used with.

The standard replaces the earlier nuclear industry standard EJ/T 885-1994. Issued on 8 June 2013, it has applied since 1 October 2013.
