KBREED

BUILT
breeder

TBR / neutronics / isotope-yield surrogate for the Hyperion breeder.

Headline benchmark — honest, computed
TBR surrogate R²=1.0 vs neutronics engine; nominal net TBR 0.742; OpenMC = auto fidelity upgrade

What it accelerates

KODEX KBREED is a fast, calibrated surrogate for OpenMC / high-fidelity neutronics — reproducing its result at inference speed, so it runs inside a real-time control loop or a design search where the full computation is far too slow to call.

Use it

One line, one contract — a prediction, its uncertainty, and whether the input is in-domain.

from kronos_ml import KBREED

model = KBREED()                          # loads the trained surrogate
y, sigma, in_domain = model.predict(x)   # y = tritium breeding ratio
if not in_domain:                       # out of its trusted region
    fall_back_to_full_physics()          # KBREED abstains, never extrapolates

How to trust it

Every KODEX code wraps the shared spine — KHALO for calibrated uncertainty and KGATE for the out-of-domain gate — so it reports how confident it is and abstains rather than extrapolate. Benchmarks are computed on held-out data with a fixed seed; pre-registered misses are kept, not hidden.
