SAFETY EVALUATION BY THE OFFICE OF NUCLEAR REACTOR REGULATION l
RELATED TO AMENDMENT NO.126 TO FACILITY OPERATING LICENSE NO. DPR-51 ARKANSAS POWER AND LIGHT COMPANY ARKANSAS NUCLEAR ONE, UNIT NO. 1 DOCKET NO. 50-313 INTRODUCTION By letter dated June 16, 1988 as supplemented on April 27, 1989, Arkansas Power Specifications (y (AP&L or the licensee) requested an amendment to the Techni and Light Compan TSs) appended to Facility Operating License No. DPR-51 for Arkansas Nuclear One, Unit 1 (ANO-1). The proposed amendment would revise the Technical Specification surveillance test frequency requirements for +he radiation monitoring system.
EVALUATION The proposed amendment would change Technical Specification Table 4.1-1 regarding Item 28, " Radiation Monitoring System other than containment high range monitors."
The " Channel Description" would be changed to identify two subparts of the Radiation Monitoring System: Process Monitoring System and Area Monitoring System. Each subpart would have separate surveillance test frequencies specified.
The channel check frequency for both subparts would be increased to once per shift from once per week. The channel functional test frequency for the Process Monitoring System would be decreased from monthly to quarterly, and would remain monthly for the Area Monitoring System. Finally, the channel calibration frequency for both subparts would be decreased to once per 18 months from once per quarter.
These proposed surveillance frequencies are consistent with the Radiological Effluent Monitoring Instrumentation Technical Specifications, which require a quarterly channel functional test and a channel calibration every 18 months.
-They are also identical to the Radiation Monitoring System surveillance frequencies specified in the Arkansas Nuclear One, Unit 2, Technical Specifications, which are consistent with the Combustion Engineering Standardized Format Technical Specifications and the channel calibration frequency (during refueling outages) indicated in Section 12.3 of the Standard Review Plan. Additionally, the decrease in the channel calibration frequency to once every 18 months is justified by a significant record of reliable instrument performance.
Based on the above considerations the staff has determined that the proposed changes are acceptable.

' o ENVIRONMENTAL CONSIDERATION The amendment involves a change in the installation or use of a facility component located within the restricted area as defined in 10 CFR Part 20.
The staff has determined that the amendment involves no significant increase in the amounts, and no significant change in the types, of any effluents that may be released offsite, and that there is no significant increase in individual or cumulative occupational radiation exposures.
The Comission has previously issucd a proposed finding that the ahnendment involves no significant hazards consideration, and there has been no public coment on such finding. Accordingly, the amendment meets the eligibility criteria for categorical exclusion set forth in 10 CFR Section 51.22(c)(9).
Pursuant to 10 CFR 51.22(b), no environmental impact statement or environ-mental assessment need be prepared in connection with the issuance of the amendment.
CONCLUSION The staff has concludeo, based on the considerations discussed above, that:
(1) there is reasonable assurance that the health and safety of the public will not be endangered by operation in the proposed manner, and (2) such activities will be conducted in compliance with the Comission's regulations, and the issuance of the amendment will not be inimical to the common defense and security or to the health and safety of the public.
