20555 IE Bulletin No. 79-16 Date July 26, 1979 Page 1 of 4 VITAL A"IA ACCESS CONTROLS Description of Circumstances An attempt to damage new fuel assemblies occurred recently at an operating nuclear reactor facility.
During a routine fuel luspection, the licensee discovered that a chemical liquid had been poured over 62 of 64 new fuel assemblies. Analysis indicates that the chemical liquid was sodium hydroxide, a chemical stored and used onsite.
The licensee stores new fuel assemblies in dry storage wells on the same elevation as the spent fuel pool within the Fuel Building, a vital area.
Access to the building is controlled by use of a coded key card which elec-tronically unlocks the alarmed personnel portals The licensee issues coded key cards to both licensee and contractor personnel alter the successful com-pletion of a background screening program.
In addition, licensee site manage-ment certifies monthly that each individual has the need for a coded key card in order to perform required duties.
Further access within this building is not limited by other barriers or controls As a result of this incident, an initial licensee audit determined that several hundred licensee and contractor personnel had access to this.rea during the period when the attempt to, damage the fuel was made The aufit also revealed that one coded key card reader at a vital area portal was inaccurately recording access data at the alarm station.
Also discovered during this audit were indications of frequent " tailgating" on access through the portals. Tailgating occurs when more than one person passes through a portal on one person's authorized access Their passage is therefore not recorded, and unauthorized persons could gain entry in this manner.
Tailgat.ing does not include author-ized access controlled by an escort.
10 CFR 73.55(a) requires the licensees to protect against industrial sabotage committed by an insider in any position.
10 CFR 73.55(d)(7) states that access to Vital Areas shall be positively controlled and limited to individuals who are authorized access to vital equipment and who require such access to perform their duties.
Specific commitments implementing this regulation are described in each licensae's approved Security Pic~ ~.
