SUBJECT:

BRAIDWOOD STATION SECURITY ISSUE RESOLVED

Dear Mr. Kingsley:

Section S3.b.1of Inspection Report No. 50-456/98071; 50-457/98017, dated November 10, 1998, identified an unresolved security item pertaining to the adequacy of compensatory measures implemented for a section of the vehicle barrier system. The issue is briefly described below.

Section 5.2.1.1 of the Braidwood Station Security Plan states that the vehicle barrier system '

(VBS) meets the requirements of 10 CFR 73.55(c)(7) and (8), and also commits to

! compensatory measures for degraded portions of the VBS equivalent to those identified in

' Nuclear Energy institute (NEI) Document 96-01 " Guidelines For Operational Planning and Maintaining Integrity of Vehicle Barrier Systems (VBS)", dated February 1996.

l l

- The inspector's review of documentation of compensatory measures and interviews disclosed that a portion of the VBS was degraded to allow protected area entry and exit of the steam

generators. In both cases, the jersey barriers that make up part of the VBS were unpinned l and left in that condition for periods up to four days. The licensee's Corporate Security L

Procedure (CNSG No. 4, Revision 1, " Operational Planning and Maintaining Integrity of l Vehicle Barrier Systems", dated August 1996), allowed unpinned jersey barriers to be used for compensatory measures.

We were unsure if the compensatory measures implemented were adequate, although they did comply with the corporate security procedure. The unresolved item was what compensatory measures were required if the VBS degradation was the result of licensee preplanned actions which resulted in the VBS not meeting the criteria of 10 CFR 73.55(c)(7),

and an analysis showed that the barriers had to be anchored to be effective.

NRC Headquarters has concluded that the compensatory measures implemented (unpinned

jersey barriers) were adequate, for a short period of time, because of t5e existence of two protected area perimeter fences, and an operational perimeter alarm system.
