1 of 4 VITAL AREA ACCESS CONTROLS Description of Circumstances:
An attempt to damage new fuel assemblies occurred recently at an operating nuclear reactor facility.
During a routine fuel inspection, 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 samu elevation as the spent fuel pool within the Fuel Building, a vital area.
Access to the building is controlled by use of a coded keycard which elec-tronically unlocks the alarmed personnel portals.
The licensee issues coded keycards to both licensee and contractor personnel after 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 keycard 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 area during the period when the attempt to damage the fuel was made.
The audit also revealed that one coded keycard 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 tnrough a portal on one person's authorized access.
Their passage is therefore not recordeo, and unauthorized persons could gain entry in this manner.
Tailgating does not include author-ized access controlled by an escort.
Discussion of Applicable Requirements:
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.
