HATCH MODIFICATION COULD HAVE IMPACTED COMPLETION OF A CONTROL ROOM EVACUATION
"At 1104, 3/19/03, while operating at 100% power, Callaway Plant discovered that a modification performed on an equipment hatch impacted the ability to complete a Control Room evacuation in the event of a fire. The modification had installed a hatch in a floor penetration between elevations that had a latching mechanism installed on the bottom side of the hatch but the associated T-handle was not initially installed on top of the hatch. The latch mechanism could still be operated from the top via a large opening in the hatch where a ladder passed through the hatch. This modification could have resulted in the inability to access the area and valves below the hatch that would require manipulation during a Control Room evacuation. When this problem was identified, a T-handle was installed on top of the hatch for operating the latching mechanism and resolved the situation.
"This event affects our commitment for the Control Room Fire Safe Shutdown analysis and is being reported as an unanalyzed condition per 10CFR50.72(b)(3)(ii)(B)."
The licensee has notified the NRC Resident Inspector.

"This event is being retracted. Upon further Engineering evaluation, it was determined that there was sufficient time to allow using an alternate route to access and operate the valve located on the elevation below the equipment hatch. Thus this event did not represent an unanalyzed condition and is not reportable."

SINK HOLE IN SITE STABILIZATION POND
"The site stabilization pond has developed a sink hole which has created a partial bypass of the normal treatment system from an unauthorized release point. The stabilization pond receives water pumped from a Storm Drain Basin which collects storm drainage from various areas around the site. This release from an unauthorized discharge point requires notification to the State of North Carolina in accordance with our NPDES permit. This report initiated per [50.72(b)(2)(xi)] due to State of North Carolina notification."
The licensee has notified the NRC Resident Inspector.
