Attila® – Reactor Analysis
 
 
3-D analysis (1/6th core reflected) of the NGNP High Temperature Gas Cooled Reactor. All fuel rods explicitly modeled. Attila keff = 1.2591, MCNP keff = 1.2516. Work funded through a DOE Phase I SBIR grant.
  
Features and Benefits
    Global solution calculated, ideal for determining power level distributions
    Built-in depletion capability for complete fuel cycle analyses
    CAD integrated, geometry accurately represented
    Restart from previous solution field, ideal for predicting reactivity worth
    Compatible with established thermal, structural, and fluids analysis codes
    Easy to set-up and fast-to-verify

Maximum percent error in the local pin power for participating codes in the C5G7 MOX Benchmark (NEA/NSC/DOC(2003)16). Attila was the only solver to be within the 99% confidence interval of the MCNP reference solution for all pin powers.
