NB/T 25068-2017Technical specifications for hydrogen, oil and water systems of generators in nuclear power plants (English PDF)

NB/T 25068-2017 is the English-translated version of 核电厂发电机氢油水系统技术条件.

NB/T 25068-2017 is a recommended standard of the Chinese energy industry dealing with the hydrogen, oil and water systems of generators in nuclear power plants.

It sets requirements for the performance design and the physical layout design of these systems, and for their operating supervision and periodic testing.

It is written for generators cooled by the water-hydrogen-hydrogen arrangement or wholly by hydrogen, and it governs the equipment outside the generator body itself, meeting the body only at the interface design.

Similar systems in thermal power stations may be designed with reference to it. It quotes GB 3836.1, GB/T 7064, GB 11120, GB 50177, DL 5068, DL/T 5204, JB/T 6517, NB/T 20193 and TSG D0001. Issued on 10 February 2017, it has applied since 1 July 2017.
