Accident Classified As:
Cause of Problem: Equipment Failure
the episode was the result of a January 15th shut down of the #2 SRU due to and emergency safety shutdown of the unit following a malfunction of the primary (north) Combustion Blower for the SRU Thermal Reactor. MOUSA started the backup (south) blower, but this machine exhibited high vibrations, so MOUSA was forced into a safety shutdown of the #2 SRU.
Discharge Preventable - No
Notes/Remedial Actions
This incident was not preventable because the blower malfunction was not a predictable event. Remedial Measures - MOUSA repaired the North blower and returned the unit to normal operation without further incident. MOUSA is considering a redesign of the blower system.
