SUBJECT:

Arkansas Nuclear One - Units 1 and 2 Docket Nos. 50-313/50-368 License No. DPR-51 and NPF-6 Followup to Response to Inspection Report 50-313/87-31; 50-368/87-31

Dear Mr. Callan:

During the inspection conducted by Mr. R. A. Caldwell of your office during the period September 21 - 25, 1987 (Inspection Report 50-313/87-31; 50-368/87-31), a violation was identified concerning a deficiency in the E-field perimeter alarm system.

In response to this violation, Arkansas Power and Light stated that a proposed modification was being tested and would be installed on the majority of the E-field if determined to be satisfactory. This modification did prove adequate and has been installed where applicable.

However, certain sections of the E-field perimeter alarm system did not lend themselves to this particular modification. Arkansas Power and Light initially proposed evaluating these sections on a case-by-case basis and submitting to the NRC a schedule for the completion of modifications to these sections. However, it has been recognized that the approach to resolvlng deficiencies with the perimeter security system has historically been on a case-by-case basis, dealing only with the specific problem that has been identified. Therefore, rather than sinply devising a fix for the immediata problem with the E-field perimeter alarm system, Arkansas Power and Light has chosen to take a more comprehensive approach to the entire perimeter i security system, which includes the intrusion detection system (E-field and microwave), the surveillance equipment, and the physical barrier associated with the perimeter. The objective of this Perimeter Security System l Improvement Project is improvement of the system using a programmatic approach l

q instead of a problem-oriented approach.

.The first step towards accomplishing this objective will be the development of a design basis for this portion of the security program. This proposed document will contain a compilation of the design criteria to be used for the E-field, microwave, cameras, fence and certain special areas. These special areas include loading docks, major personnel entrances into the plant, and vehicular entrance points. It will also include major design criteria on support systems for the above, for example, power distribution systems and lighting levels in the isolation zone. To aid in the development of this basis, past inspection reports-and reviews of other utility programs will be used as well as internal and external security experts.

Upon approval of the design basis, the next step will be to conduct a review of the perimeter security system. The existing systems will be compared to the new design basis and deviations identified, grouped, and prioritized.

The resolution may include modifications and/or revision to the industrial security plan. At this stage past problems will be factored in and resolved, including the existing deficiency in the E-field perimeter alarm system.

After this review an action plan to accomplish the necessary modifications will be developed. Resolutions will be accomplished in a timely manner consistent with their individual significance and complexity.

The following schedule has been developed for implementing this project:

Design Basis Document (Draft) February 15, 1988 Approval of Design Basis March 7, 1988 System Review March 31, 1988 Action Plan Developed April 18, 1988 Approval of Action Plan June 2, 1988 The action plan and implementation schedule will be provided for your information by June 17, 1988.

Until the E-field perimeter alarm system deficiency is corrected for the entire system, sections that are deficient will remain posted.

Very truly your
