Dataset goal

Detect when breeder depletion state stops predicting extraction performance.

This is the quiet failure mode:

breeder inventory looks adequate

neutron conditions look nominal

observed TBR slides because extraction decouples

Required outputs

drift_gradient

decoherence_score

decoupling_flag

Optional classification

primary_decoupling_mode

none

transport_delay

extraction_drop

inventory_trap

mixed

Typical decoupling patterns

extraction_drop
extraction efficiency falls faster than depletion would predict

inventory_trap
lithium inventory declines and helium rises
but extraction does not track generated tritium

transport_delay
generated and extracted remain close
but timing lag grows and coherence weakens

Use cases

blanket operations and fuel-cycle monitoring

tritium plant tuning and de-trapping cycles

early warning before TBR drops below self-sufficiency
