✗ A. Incorrect. Plausible because the upender in the horizontal position is a safe position for a fuel assembly IAW AB.FUEL, if P-10 is not available or the assembly is indexed above the upender.
✗ B. Incorrect. Plausible because the candidate may believe that any core location is safe at this point of the fuel reload.
✗ C. Incorrect. Plausible because the candidate may confuse the safe location in the FHB (X-3) with the one in Containment (P-10).
