Narrative
At approximately 1810 on november 30, 2019, as technicians were completing a seal change on the outboard seal of pump 310 at brackettville pump station, a fire ignited on the outer edge of the seal cartridge. The incident occurred at startup of the unit. The station fire eye caught the flame and activated the esd loop, shutting the pump station down for approximately 20 minutes. The technicians onsite were able to quickly extinguish the incipient stage fire and there were no injuries sustained. (the station was restarted with the other pump [2 pump units at this station] at 1830 hours). It was determined that this incident was caused by friction of the seal clips rubbing against the locking collar between the seal and the pump shaft along with a potential atmospheric leak of the seal. It was also determined that the seal clips were potentially not completely pulled out and thus could have been partially engaged on the seal sleeve. During the repair following the fire, it was determined that there was not enough clearance between the seal cartridge and the locking collar allowing for the clips to potentially rub against the collar. There was no measurable release and it is estimated at less than one gallon. This incident was reported because of the incipient fire. Redipump llc performed a site report on this seal failure and determined that the mechanical seal p310 was found set to the shaft in an unloaded position. The set clips were not properly engaged in run position. To prevent this from reoccurring, dcp will start with a visual inspection of the clips. They must be fully engaged in the seal sleeve. No gap between clip and gland register face. Sleeve groove must be fully visible with back edge even with gland face. Clips must be squarely moved into the run position dcp will also ensure that existing procedures be modified to add the correct level of detail for seal repair for all of the different types of pumps we have at our stations. Nrc and rrc notified by john pontious for the fire - spill volume did not meet reportable criteria.
