1. Plant? Palo Verde 2. What is your criteria for posting Hot Spots? An accessible localized point with a contact radiation level which is 100 mrem/hr or greater and is greater than or equal to five times the radiation level 12" away from the point. (INPO 05-008, III.C.3.b)
3. At what point do you flush or shield Hot Spots for personnel exposure? Depends on occupancy of the affected area (is there a significant dose savings) and what, if any impact there is based on plant risk management (equipment operability / nuclear safety). 4. If the Hot Spot is not expected to create a dose gradient in the area being accessed, what are your actions (track / trend)? All hot spot are entered into our tracking / trending system. If it is flushed, shielded, or simply posted / labeled we use all of this information as part of our source term reduction program.
