Other parts for nuclear reactors

This code covers parts for nuclear reactors that are not otherwise specified in the listed neighbouring categories. It does not cover the reactor itself, isotope separators or their parts, or unirradiated fuel elements in casings with special transport or fastening fittings.

For example

A control-rod drive part for a nuclear reactor, not an isotope-separator part or an unirradiated fuel element in a casing with special transport or fastening fittings
A coolant-system part for a nuclear reactor, not an isotope-separator part or an unirradiated fuel element in a casing with special transport or fastening fittings
