i e a l l f 1. INTRODUCTION 1 Arkansas Nuclear One is a two unit plant consisting of a B&W (Unit.1) and CE (Unit 2) desigr.. Both liquid and gaseous effluents are released in i accordance with the respective units Technical Specifications. This report is a summary of the effluent data in accordance with Unit 1 Technical-Specification 6.12.2.6 and Unit Two Technical Specification 6.9.3. This i report provides the following information required by those references l 1. Routine radioactive effluent release reports covering the operation of .I the unit during the previous 6 months of operation. [ 2. Description of unplanned releases to unrestricted areas. 3. Description of changes to ODCM. 4. Description of changes to PCP. -j 5. Summary of the hourly meteorological data collected of the previous calendar year. (This data is included in the first report of each year.) 6. Summary of radiation doses due to radiological effluents during the. l previous calendar year. (This data is included in the first report of each year.) { i 7. Radiation dose to members of the public due to their activities inside a the site boundary. (This data is included in the first report of each [ year.) l 1 8. Description of licensee initiated major changes to the radioactive i waste systems during the previous calendar year. (This data is included in the first report of each year.) This report covers the period of July 1, 1992 through December l 31, 1992. [ 2. REGULATORY LIMITS l Unit one and Unit Two Technical Specifications contain the limits to which Arkansas Nuclear One must adhere. Because of the ALARA philosophy at ANO, an attempt is made to reduce the amount of radiation } released to the environment to as low as reasonable achievable. The f following are the limits required by the Unit Tech. Specs. f d A. Gaseous Effluents I 1. Dose rate due to radioactive materials released in gaseous effluent j to unrestricted areas shall be limited to the following-t a. Noble gases Less than or equal to 500 mrem / year to the total body Less than or equal to 3000 mrem / year to the skin 1 i i ?

m f 4 6 b. Iodine-131, tritium, and for all radionuclides in particulate l form with half lives greater than 8 days. Less than or equal to 1500 mrem /yr 2.

Liquid Effluents i 1. The concentration of radioactive material released to the discharge } canal shall be limited to the concentration specified in 10 CFR Part 20, Appendix B, Table II, Column 2 for radionuclides other than dissolve or entrained noble gases. For dissolved or entrained noble p gases, the total concentration released shall be limited to 2E-4 microcuries/ml. 2.

SUMMARY

OF GASEOUS EFFLUENT DATA As required by Regulatory Guide 1.21 Rev. 1, a summary of data for gaseous releases is provided below. The summary of gaseous releases from the radwaste effluent system during July 1, 1992 and December 31, 1992 is as follows: l Unit 1 Unit 2 Number of releases: 77 84 Total time for all releases: 498704 467487 (minutes) Maximum t.me for a release: 10429 10748 (minutes) Average time for a release: 6477 5565 (minutes) Minimum time for a release: 10 0.167 (minutes) The Unit 1 gaseous releases consisted of: 18 Emergency Feedwater (EFW) Pump releases - These releases were a result of the surveillances to the EFW pump. Four of these 18 releases were the result of Unit 2 surveillances of the EFW pump. These releases are attributed to Unit 1 because Unit 1 stram was used for the surveillance. 4 Waste Gas Decay Tank releases. 55 weekly vent releases. The Unit 2 gaseous releases consisted of: 10 Emergency Teedwater (EFW) Pump releases - These releases are a result l of the surveillances to the EFW pump. 1 Reactor Building Purge f 1 Main Steam release i 5 Steam Generator releases i 3 Volume Control Tank (VCT) releases f 1 Unplanned Main Steam relief valve release 63 Weekly vent releases i t t i i

l [ 7. UNPLANNED RELEASES i A. For the purpose of this report, an unplanned release is any release of radioactive material that is released to the environment due to causes not controlled by plant personnel. During the third and fourth quarters of 1992, there was one unplanned release, 2GR92-176. This release resulted from a defective isolation valve and a post-maintenance test. The following is the dose contribution of this release. Release start times October 28, 1992 at 1915 l Release stop time: October 28, 1992 at 1915 Release volume

108632 cubic feet Release duration 0.167 minutes Camma Air Dose = 0.00E+00 mrad Beta Air Dose = 0.00E+00 mrad j

ITP Dose = 1.37E-08 mrem Which is 9.13e-8 percent of the yearly limit (15 mrem / year.) i

1. Description of occurrence.

l l During October 1992, work was performed on 2CV-0305 (Atmospheric Dump Valve). Upon completion of this work, the post maintenance testing consisted of stroking the valve. Normally this valve is isolated upstream prior to stroking. Because the upstream valve was defective full isolation was not accomplished and upon stroking the dump valve a steam release occurred. 2. Identify cause for exceeding the limit. No limits were exceeded during this release. 3. Explain Corrective actions taken to mitigate occurrence. t No actions were taken to mitigate this occurrence. The release was due to the stroking of a valve which lasted approximately 10 seconds. Upon completion of the stroke test no further testing was required. l 4. Define action taken to prevent recurrence. The defective valve was repaired which will allow isolation to the dump valve. 5. Summary of consequences of occurrence. At the time of the release, Unit 2 had a primary te secondary leak of <0.01 gpm. Because of this condition, the Unit 2 steam was contaminated. Upon opening of the dump valve, steam was released to the atmosphere. Analysis of the main steam after release resulted in only tritium being released to atmosphere. Tritium is a typical isotope released during routine operations. This release of radioactive material is very low in comparison to the typical amount of tritium release throughout the year. No abnormal consequences would be expected to occur due to this release. l i t i

l l 8. RADIATION INSTRUMEh?3LTION As required by Unit 1 and Unit 2 Technical Specifications, any radioactive effluent instrumentation inoperable for mere than 30 days shall be explained i in the next Semiannual Radioactive Effluent Release Report. During the I third and fourth quarters of 1992, no instrumentation was inoperable longer than 30 days. i 9. CRANGES TO PCP i As required by Unit 1 and Unit 2 Technical Specifications, a description of the changes to the made during the reporting period are to be included in i the Semiannual Radioactive Effluent Release Report. During the third and fourth quarters of 1992, there were no changes to the PCP.

10. CHANGES TO RADIOACTIVE WASTE SYSTEMS During 1992, there were no major changes to the radioactive waste systems.

t

11. CHANGES TO THE OFFSITE DOSE CALCCLATION MANUAL j

i During September 1992, sample station number 47 was deleted from the milk [ sample stations. This was due to the owners of the animal declining to continue participation in the environmental sample project. It has been [ determined that these changes to the sampling station will not reduce the accuracy or reliability of the dose calculations or setpoint determinations. [ In accordance with Technical Specification 3.12.1, ANO is required to obtain i milk from at least four stations. Currently ANO has 4 sampling stations and j one alternate that meet the criteria of the Tech. Spec. During November 1992, an alternate food product was added to cample station number 108.

12. METEOROLOGICAL DATA

SUMMARY

In accordance with ANO-1 and 2 Technical Specifications 6.12.26(e) and 6.9.3.4.1, respectively, in lieu of cncluding a summary of the meteorological data in this report, the 1992 data is retained at ANO. This data is available for NRC review. i t i f i i i L r e
