Palo Verde provides the following response: As part of our outage set-up, we establish a Containment Building Access Tent around the ground level personnel access hatch. This consists of double stacked Sea Vans underneath a temporary structure (scaffolding and visqueen). As the outage winds down (prior to Mode 4 entry) almost all materials exit through this access point. The remaining materials are removed either through the 2nd hatch that leads from the Containment Building into the Auxiliary Building or out through the equipment hatch which is contained by a Radwaste Yard. With three exit points materials are expeditiously removed from Containment I assume that when you say "Do you use your personnel hatch to remove items after containment is closed" you are referring to Mode 4 entry. Palo Verde has a mode 5 to 4 restraint that requires all items be removed from the Containment Building. After Mode 4 entry there can be up to 64 square feet of equipment in the Containment Building provided it is approved, accounted for, and can be removed immediately if needed. Any remaining items would be removed via the inside personnel hatch which is surrounded by a contamination area that allows for surveys and transfer into appropriate packages Please call if you'd like additional information. ********************************************************************** Seth J.

Do you have an expeditious method of getting everything out of Containment at the end of an outage before closing the equipment hatch? If so, please explain your process. Do you use your personnel hatch to remove items after containment is closed? If so, how much use does the personnel hatch get and what method do you have in place to control, package and survey equipment coming out? If you would prefer to call me, please do so at the number below.
