Watts Bar response:
Hot spots identified in general plant areas (outside of containment) are discrete locations/components that have a near contact dose rate of ≥100 mrem/hr and ≥ 5 times the 30 centimeter dose rate reading. Hot spots identified inside of containment are discrete locations/components that have a near contact dose rate of ≥1,000 mrem/hr and ≥ 5 times the 30 centimeter dose rate reading.

Our procedure gives an out for posting hot spots “per HP supervision” if the dose received would “not be consistent with ALARA”.

Question 2: Do you tag/post a “HOT SPOT” in “Inaccessible” areas. (other than LHRAs, VHRAs and Containment) Any other information you can provide about your plants HOT SPOT program is desired and welcomed. Thank you, David J.
