- Scope
- This standard specifies the technical requirements for the installation of neutron flux tubes and their supports in reactor buildings of pressurized water reactor nuclear power plants. This standard is applicable to the installation and acceptance of the neutron flux tubes (see Figure A.1 for a typical illustration) arranged at the bottom of the reactor of my country's second-generation million-kilowatt pressurized water reactor nuclear power plant. Maintenance projects can be implemented as a reference. In this standard, the scope of installation activities includes the reception, storage, transportation, installation and welding, and acceptance of neutron flux tubes. Neutron flux tubes in this standard mainly include: guide tubes, penetration parts, manual valve-seal components and supports, etc.
