NB/T 20439-2017Rules for establishing pressure-temperature limit curves for reactor pressure vessel of pressurized water reactor nuclear power plants (English PDF)

NB/T 20439-2017 is the English-translated version of 压水堆核电厂反应堆压力容器压力-温度限值曲线制定准则.

NB/T 20439-2017 is a recommended Chinese energy industry standard on the pressure-temperature limit curves of the reactor pressure vessel in pressurized water reactor nuclear power plants.

It gives the rules by which the pressure and temperature limits of the vessel are determined, both under test conditions and under normal operating conditions. Its field of application is the ferritic steel reactor pressure vessels of pressurized water reactor plants.

NB/T 20035-2011 is the standard it quotes and works with. It shares the classification F69 and the international class 27.120.20 with the other reactor vessel integrity documents of the family. Issued on 1 April 2017, it has applied since 1 October 2017.
