Licensee: Replaced JPM.

AN2R NRC: Not discriminating, majority of steps identified as critical are not because they are verification steps or reading same voltage of 4160. Replace or rewrite to incorporate problem/action, consequences if not done correctly.

Licensee: Made one voltage OOS, must inform US. First 5 steps are not critical.

AN3R NRC: Change cue to read perform calculation verification and ensure paperwork is correct. On DOS 6600-02, Page 9, initial step 11.c.
