## Discrepancy

UPON THRUST REDUCTION TO CLIMB, NR 2 ENGINE HAD TWO COMPRESSOR STALLS BEFORE THRUST LEVER COULD BE MOVED TO IDLE.  EGT EXCEEDED LIMITS; ENG 2 FAIL ON ECAM.  NR 2 ENGINE WAS SHUTDOWN IAW ECAM ACTIONS, FIRE BOTTLE WAS DISCHARGED AND AIRCRAFT DIVERTED TO LAX, (EMERGENCY DECLARED).  MAINTENANCE REMOVED AND REPLACED THE NR 2 ENGINE.
