NB/T 20195-2012Procedure for reactor core thermal power measurement of pressurized water reactor nuclear power plants (English PDF)

NB/T 20195-2012 is the English-translated version of 压水堆核电厂堆芯热功率测量规程.

NB/T 20195-2012 is a recommended energy industry standard of China that sets the procedure for measuring the thermal power of a pressurized water reactor core.

It states the principles, the methods and the basic requirements of the core thermal power measurement test, which establishes core thermal power through a secondary loop heat balance so that the reactor can be operated safely.

It is written for pressurized water reactor nuclear power plants, while heavy water reactors and other reactor types may follow it as a reference. Flow measurement rests on the two international documents it cites, ISO 5167-2003 and ISO 15377-1998. Issued on 19 October 2012, it has applied since 1 March 2013.
