UNITED STATES NUCLEAR REGULATORY C0FMISSION DOCKET NO. 50-368 ARKANSAS POWER AND LIGHT C0b7ANY ARKANSAS NUCLEAR ONE, UNIT 2 NOTICE OF ISSUANCE OF AMENDFENT TO FACILITY OPERATING LICENSE The U. S. Nuclear Regulatory Cornission (the Cornission) has issued Amendment No. 9 to Facility Operating License No. NPF-6 to Arkansas Power and Light Company for operation of Arkansas Nuclear One, Unit 2 (the f acility) located at the licensee's site in Pope County, Arkansas. The amended license is effective as of its date of issuance.
The amendment changes the Technical Specification 3.6.1.4 by reducing the minimum-initial containment temperature and pressure to 50 degrees Fahrenheit and a negative 3.0 pounds per square inch gauge, respectively. This change C, lows greater flexibility in plant operations and is consistent with the Commission's conclusions, regarding containment integrity, stated in Supplement No. 2 to the Safety Evaluation Report. Also, the steam generator low water level trip setpoint specified in Technical Specification Tables 2.2-1 and Table 3.3.4 is changed to a value of greater than or equal to 46.5 percent.
The setpoint change is based on replacing the original instrument transmitters with new transmitters which have greater accuracy in measuring the low water level in the steam generators.
The Commission has made appropriate findings as required by the Atomic Energy Act of 1954, as anended (the Act), and the Comaission's regulations in 10 CFR Chapter I, which are set forth in the amended license.

The application for the amendment complies with the standards and requirements of the Act and the Commission's regul at ions.
The Commission has determined that the issuance of this amendment will not result in any significant environmental impact and that pursuant to 10 CFR Section 51.5(d)(4) an environmental impact statement, or negative declaration and environmental impact appraisal need not be prepared in connection with issuance of this amendment.
