Division Systems, Equipment and Components

0A001"Nuclear reactors" and specially designed or prepared equipment and components therefor, as follows:

1. a..

   "Nuclear reactors" capable of operation so as to maintain a controlled self-sustaining fission chain reaction;

2. b..

   Metal vessels, or major shop-fabricated parts therefor, specially designed or prepared to contain the core of a "nuclear reactor", including the reactor vessel head for a reactor pressure vessel;

3. c..

   Manipulative equipment specially designed or prepared for inserting or removing fuel in a "nuclear reactor";

4. d..

   Control rods specially designed or prepared for the control of the fission process in a "nuclear reactor", support or suspension structures therefor, rod drive mechanisms and rod guide tubes;

5. e..

   Pressure tubes specially designed or prepared to contain fuel elements and the primary coolant in a "nuclear reactor" at an operating pressure in excess of 5,1 MPa;

6. f..

   Zirconium metal and alloys in the form of tubes or assemblies of tubes in which the ratio of hafnium to zirconium is less than 1:500 parts by weight, specially designed or prepared for use in a "nuclear reactor";

7. g..

   Coolant pumps specially designed or prepared for circulating the primary coolant of "nuclear reactors";

8. h..

   'Nuclear reactor internals' specially designed or prepared for use in a "nuclear reactor", including support columns for the core, fuel channels, thermal shields, baffles, core grid plates, and diffuser plates;

   Note: In 0A001.h. 'nuclear reactor internals' means any major structure within a reactor vessel which has one or more functions such as supporting the core, maintaining fuel alignment, directing primary coolant flow, providing radiation shields for the reactor vessel, and guiding in-core instrumentation.

9. i..

   Heat exchangers (steam generators) specially designed or prepared for use in the primary coolant circuit of a "nuclear reactor";

10. j..

    Neutron detection and measuring instruments specially designed or prepared for determining neutron flux levels within the core of a "nuclear reactor".
