When performing Dry cask do you use a criticality alarm? EF2 - haven't done dry cask yet, re-fuel floor has installed criticality monitors, portable ARMS will be used for GA monitors
If you are using the RMS-3 do you ever get false alarms due to power
transients? If so, what have you done to prevent it? EF2 - I'm not
aware of having this problem at EF2. Suggestion - try using power
conditioner or power conditioner / ups, we use these on equipment in
areas where AC power is poor quality
Is there a better alternative to the RMS-3? ????? no recommendation

Sent by: [email protected]
Browns Ferry is currently having a campaign of dry cask operations.
Last week a power transient caused our RMS-3 to alarm. The refuel
floor was appropriately evacuated until the cause could be determined
and surveys performed. We have gotten an alarm in the past during
electrical board switching and need to find away to prevent the false
alarm. The vendor gave us a few suggestion on modifying the detector
and set up but I am hesitant to try it since it is a piece of safety
equipment.
I have a couple questions:
When performing Dry cask do you use a criticality alarm?
If you are using the RMS-3 do you ever get false alarms due to power
transients? If so, what have you done to prevent it?
Is there a better alternative to the RMS-3?
Thanks in advance for your time
