DER/SPRC/LEPh - Validation of APOLLO3® SCRAP calculation route for depletion calculations of small fast reactor core

Objective: extend and validate the deterministic SCRAP route (APOLLO3®) for small SFR cores, including core depletion.

• Work: define/perform SCRAP lattice + 3D core calculations; compare k-eff, power distribution, etc., against references: TRIPOLI‑4® (steady-state Monte Carlo) and a more accurate APOLLO3® route (for depletion).
• Assess accuracy vs computational cost; calibrate simplifying models/approximations.
• Tools: APOLLO3®, TRIPOLI‑4®, Python.
• Profile: nuclear engineering (last-year Master or equivalent), neutronics theory and numerical methods, Python basics.
