I Contrary to the above, on April 10, 1987, at approximately 1005, access to the refueling cavity, an area with whole body radiation intensities in excess of 100 mR/hr, was not barricaded nor conspicuously poste The above multiple instances of failure to adequately control high  ;

radiation areas collectively constitute a Severity Level IV violation (Supplement IV).

Maine Yankee Resoonse Maine Yankee took the following immediate action regarding maintaining the proper posting and barricading of high radiation areas in Containment  !

identified ~1n a, b, and c abov The area underneath the hot spot which produced dose rates greater than 100 mR/hr at the -2 foot elevation adjacent to Loop #1 access in i containment was immediately barricaded and posted at a point where whole body dose rates were less than 100 mR/h Although the access to the #2 RCP had been properly posted and barricaded, the workers who were continuously moving in' and out of the area improperly took down the barricade to provide easy access and failed to replace it each time they exited the high radiation area. Upon identification of the barricade being down, the barricade and posting was immediately repositioned. The technicians covering the work area were instructed to maintain the barricade across the stairway. The workers and their foremen were also instructed about the need to keep radiological barricades in place at all time The access to the refueling cavity had also been properly posted and barricaded. When workers exited the refueling cavity they took down )

More frequent-supervisory inspections of containment work locations have been conducted, especially i the areas referenced above, to verify the location.and posting of barricades l for high radiation area I i
