Appendix A to Part 110 - Illustrative List of Nuclear Reactor
Equipment Under NRC Export Licensing Authority Note:
A nuclear reactor basically includes the items within or
attached directly to the reactor vessel, the equipment which
controls the level of power in the core, and the components which
normally contain or come in direct contact with or control the
primary coolant of the reactor core.
(1) Reactor pressure vessels, i.e., metal vessels, as
complete units or major shop-fabricated parts, especially designed
or prepared to contain the core of a nuclear reactor and capable of
withstanding the operating pressure of the primary coolant.
(2) On-line (e.g., CANDU) reactor fuel charging and discharging
machines, i.e., manipulative equipment especially designed
for inserting or removing fuel in an operating nuclear reactor.
(3) Complete reactor control rod system, i.e., rods
especially designed or prepared for the control of the reaction
rate in a nuclear reactor, including the neutron absorbing part and
the support or suspension structures therefor.
(4) Reactor primary coolant pumps or circulators, i.e.,
pumps or circulators especially designed or prepared for
circulating the primary coolant in a nuclear reactor.
(5) Reactor pressure tubes, i.e., tubes especially
designed or prepared to contain both fuel elements and the primary
coolant in a nuclear reactor.
(6) Zirconium tubes, i.e., zirconium metal and alloys in
the form of tubes or assemblies of tubes especially designed or
prepared for use as fuel cladding in a nuclear reactor.
(7) Reactor internals, e.g., core support structures, control
and rod guide tubes, fuel channels, calandria tubes, thermal
shields, baffles, core grid plates, and diffuser plates especially
designed or prepared for use in a nuclear reactor.
(8) Reactor control rod drive mechanisms, including detection
and measuring equipment to determine neutron flux levels within the
core of a nuclear reactor.
(9) Heat exchangers, e.g., steam generators especially designed
or prepared for the primary, or intermediate, coolant circuit of a
nuclear reactor or heat exchangers especially designed or prepared
for use in the primary coolant circuit of a nuclear reactor.
(10) External thermal shields especially designed or prepared
for use in a nuclear reactor for reduction of heat loss and also
for containment vessel protection.
(11) Any other components especially designed or prepared for
use in a nuclear reactor or in any of the components described in
this appendix.
