ABSTRACT
As a result of the diversion path analysis (see previous chapter), two different control tasks have to be solved to verify an international tritium control agreement. They are dealt with in this chapter:
Type I: Verify nonproduction. This has to be carried out at declared facilities with inadvertent, actual, or potential production capacities of more than one significant quantity within one inspection period (1 g/y). Verification of nonproduction relies on the nondestructive analysis of possible irradiation targets at nuclear reactors (see Section 3.3.3) to ensure the absence of the raw material for tritium breeding (especially lithium-6). Inspected fuel will be further controlled with containment and surveillance (see Section 3.5). Any tritium produced has to be verified for nonremoval (see type II) after the initial inventory has been determined (see Section 3.4.2).
