Manual QPTR calculation at 100% power with dropped rod 204: N42 quadrant shows highest power tilt — N42T = 1.025, N42B = 1.023 (+/- 0.002). Maximum Power Tilt exceeds 1.02 limit, requiring entry into TS 3.2.4. Alternate path JPM — data drives an UNSAT result. OHAs E-46 (LOWER SECT DEV ABV 50% PWR) and E-38 (UPPER SECT DEV ABV 50% PWR) illuminated as initial conditions.

Manual QPTR calculation procedure: for each upper and lower detector (N41-N44), divide measured current by the REM 100% current value to get the detector ratio. Sum ratios, divide by number of operable detectors (4) to get average. Divide each detector ratio by average to get the power tilt. If Maximum Power Tilt exceeds 1.02, refer to TS LCO 3.2.4 and record surveillance as UNSAT. A dropped rod (e.g. 2D4) causes asymmetric flux distribution resulting in QPTR >1.02 in the affected quadrant (N42).
