Subject: LANDING OF NATIONAL GUARD HELICOPTER IN OWNER CONTROLLED AREA

Reportable Event Number: N/A

Discussion:

Preliminary information indicates that at approximately 5:30 p.m. (PDT), 
June 27, 1995, a military CH-47 helicopter landed on a portion of the    
breakwater surrounding (and outside of) the Intake Structure Protected   
Area at Diablo Canyon. The breakwater in this area is flat and provides  
an adequate landing area. After landing, two persons exited, checked     
different parts of the helicopter, and then the helicopter departed. The 
helicopter was atop the breakwater for approximately 2 minutes. The      
security organization implemented an increased alert status and          
dispatched security officers to check the helicopter. The helicopter     
departed before their arrival at the landing site. Diablo security used  
their video system to take a photograph of the helicopter. The licensee  
subsequently confirmed that the helicopter belongs to the National Guard 
from Camp Roberts approximately 50 miles from the plant. The licensee had
a discussion with the Commander from Camp Roberts on June 29, l995,      
concerning the event and the National Guard is investigating the         
incident.                                                                

Regional Action:

Notified IAT, and discussed actions taken by licensee security force     
during the event and subsequent follow actions with Camp Roberts.
