It is always possible to remove fuel early from any reactor and have low burnup.

Often, North Korea has unloaded the reactor before reaching the maximum burnup level.

Burnup Tuesday would not address the eviction or refunds for events.

It is also possible to survey and trim the ends of high-burnup fuel to obtain low-burnup fuel.

Reprocessing mixes the low-burnup fuel with the high burnup fuel.

New reactors have higher burnup so their spent fuel is even less useful for possible weapons production.

That means that reprocessing actually reduces the risk of proliferation by mixing low and high burnup fuel regions.
From the guardian.co.uk
A full core consists of 8,000 fuel rods and can yield a maximum of 27-29 kg of plutonium if left in the reactor for optimal burnup.

Developing particle fuel capable of achieving very high burnup levels will also reduce the amount of used fuel that is generated by HTGRs.

The amount of fuel used up (as in a nuclear reactor)
In nuclear power technology, burnup (also known as fuel utilization) is a measure of how much energy is extracted from a primary nuclear fuel source. ...
Measure of thermal energy released by nuclear fuel relative to its mass, typically Gigawatt days per tonne (GWd/tU).
Amount of thermal energy generated per unit mass of fuel, expressed as Gigawatt-Days Thermal per Metric Ton of Initial Heavy Metal (GWDT/MTIHM), rounded to the nearest gigawatt day.
The reduced reactivity of spent fuel that occurs from the net depletion of fissile [see fissile definition] nuclides [ see nuclides definition] and the net increase in fission and activation product neutron [see neutron definition] absorbers (poisons) is considered. ...
