Subject:

Annual Radioactive Effluent Release Report for 2003 Arkansas Nuclear One - Units 1 and 2 Docket Nos. 50-313 and 50-368 License Nos. DPR-51 and NPF-6

Dear Sir or Madam:

Arkansas Nuclear One, Units 1 & 2 (ANO-1 and ANO-2) Technical Specifications (TSs) 5.6:3 and 6.9.3, respectively, require the submittal of an Annual Radioactive Effluent Release Report. IOCFR72.44(d)(3) also requires the annual submittal of a summary of effluents from the independent spent fuel storage facility. The purpose of this letter is to fulfill these reporting requirements for the 2003 calendar year at ANO. Liquid and gaseous release data show that the dose from both ANO-1 and ANO-2 was considerably below the Offsite Dose Calculation Manual (ODCM) limits, while no effluents were attributed to the spent fuel stored in the independent spent fuel storage installation. This data reveals that the radioactive effluents had an overall minimal dose contribution to the surrounding environment. Pursuant to ANO-1 TS 5.5.1 and ANO-2.

TS (3.14, the ODCM is also submitted as an attachment to the Annual Radioactive Effluent Release Report.

ANO discovered that a calculational error resulted in previous Annual Radioactive Effilent Release Reports containing discrepancies regarding the average time of liquid and gaseous releases, as reported in Sections 3 and 4, "Summary of Liquid Effluent Data" and 'Summary of Gaseous Effluent Data," respectively. Since these errors were determined to be insignificant and had no impact on reported dose, corrected values will not b)e submitted. This condition has been corrected for the current and future submittals. Should you have any questions regarding this report, please contact Dee Hawkins at (479) 858-5589.

9. UNPLANNED RELEASES An unplanned release is defined as any release of radioactive material to the environment that does not meet the following criteria:

A. Sample analysis prior to release, and B. Release calculations performed prior to release.

During 2003, there were no unplanned releases to an unrestricted area.

10. RADIATION INSTRUMENTATION As required by ODCM Appendices 1 and 2, any radioactive effluent instrumentation inoperable for more than 30 days shall be reported in the annual Radioactive Effluent Release Report.

On June 26, 2003, while performing the monthly Noble Gas Source Check surveillance on the Unit I Containment Purge SPING (SPING #1), the high range noble gas detector (channel 9) failed high prior to the introduction of the check source. A 30 day time clock was entered per the ODCM and a Condition Report (CR-ANO-1-2003-00686) and a Work Request (#4699) were issued to document and repair the condition. It was determined -that the interface box between the SPING computer and the channel 9 detector had failed and needed to be replaced. A new interface box had to be ordered from an offsite vendor. On July 26 at 16:29 hrs the 30 day time clock expired. Condition Report CR-ANO-1-2003-00801 was issued to document the exceeded time clock. The new interface box was received onsite on August 21 and the SPING successfully repaired and the time clock exited on August 26, 2003. It is important to note that the Unit 1 Containment Vent was secured during the time SPING 1 was out of service and no gaseous releases occurred via the Containment Vent during this period.

11. CHANGES TO THE PROCESS CONTROL PROGRAM As required by ODCM Appendices 1 and 2, a description of changes made to the Process Control Program (PCP) shall be included in the annual Radioactive Effluent Release Report for the period in which the change was made effective.

Revision 1 of the Process Control Program (RW-105) was implemented on January 2, 2003.

The changes implemented under this revision were as follows:

1. The procedure classification was changed from "Non-Quality" to "Quality".
2. Section 5.4, "Administrative Controls", was revised to include the requirement that vendors performing radwaste services under IOCFR61 and 10CFR71 (Step 5.4.5) must be on the Entergy Qualified Suppliers List.
3. Section 8.0, "Requirements and Commitment Cross Reference", was updated to list correct section numbers.

There were no other changes made to the Process Control Program during 2003.
