What survey method are used when removing dry chemical fire extinguishers from the RCA? Palo Verde performs a loose and fixed contamination survey on fire extinguishers prior to release for recharge/maintenance. Since the extinguisher is sealed and typically pressurized you can assume that any contamination present is external. 2. What survey method are used when removing CO2 or water fire extinguishers from the RCA? Same as #1 above 3. Do you test the fire extinguishers to ensure they are pressurized? No 4. Do you empty the fire extinguishers prior to release? No 5. Do you have fire extinguishers in the containment during power operations? No a. If YES, have you ever detected activation products (e.g. Zn-65)? 6. Do you have any OE you could share? If you use a SAM to monitor the extinguisher for release beware that most dry chemical fire extinguishers use potassium bicarbonate (aka Purple-K) or potassium chloride (Super-K) which contain significant amounts of K-40. If you discharge the fire extinguisher prior to removal from the RCA this can drop the amount of NORM below the alarm threshold. Some fire extinguisher horns (nozzle) are made of composite materials that can also contain NORM. You could baseline your extinguishers using an MCA to determine approximate amounts and types of activity present. ********************************************************************** Seth J.
