4 EYRON NUCLEAR POWER STAf!ON UNIT 1/2 DOCRET NUMBER STN 50-454/455 RADICACTIVE EFFLUENT RELEASE REPORT Januarv , 1997 THROUGH Dec =ber , _1997 Supplemental Information

1. Regulatery Limits
a. Fission and activation gases:

Tech Spec Whole Body = 500 mrem / year Skin = 3000 mrem / year 10CFR50 Gamma = 5 mrad / quarter; 10 mrad / year Beta = 10 mrad / quarter; 20 mrad / year

b. Iodine: (summed with particulate, see below)
c. Particulates with half-lives > 8 days:

Tech Spec Organ = 1500 mrem / year 10CFR50 Organ = 7.5 mrem / quarter; 15 mrem / year

d. Liquid effluents: ,

10CFR50 Whole Body = 1.5 mrem / quarters 3 mrem / year Organ = 5 mrem / quarter; 10 mrem / year

e. Total Effective Dose Equivalent 10CFR20 TEDE = 100 mrem / year
2. Maximum Permissible Concentratian
a. Fission and Activation Gases: 10CFR20 Appendix B Table 2
b. Iodine: 10CFR20 Appendix B Table 2
c. Particulates: 10CFR20 Appendix B Table 2
d. Liquid Effluents: 10CFR20 Appendix B Table 2

.. Average Energy: This item is not applicable. Release rates are calculated using an isotopic mix rather than average energy.

4. Measurements and Approximations of Total Radioactivity
a. Fission and Activation Gases: Prior to release, the isotopic content is determined. Released activity is-calculated using volume of release, which is determined by the change in tank or containment pressure. Additional methods of calculaticn utilize historical data and assign an isotopic mix which is representative of nort..al vent stack isotopics, 9903100254 980306 PDR ADOCK 05000454 R PDR Report Page 1 of _,,21 (p:97t 9hrOOM066 wp0 ~

b. Particulate, Tritium and Iodine sampling media for_the plant vent stacks are collected and isotopically analyzed weekly for the plant vent stacks,
c. Liquids effluents: Batch releases are isotopically analyzed prior to release. Total release activity is calculated using volume of release. Total tritium activity released is calculated from the highest of a monthly circulating water blowdown composite activity or a sum of the input composite activities,
d. Analysis results which are less than the lower linit of detection

'(<LLD) are reported in units of Ci/ml unless otherwise noted, All LLD valves are listed in Attachment A.

5. Batch Releases:
a. Liquid:
1. Number of batch releases = 251 2, Total time period for batch releases = 20,095 minutes
3. Maximra time period for a batch release = 264 minutes

, 4. Averag cime period for a batch release = 80.1 minutes

5. Minimum time period for a batch release = 1 minute
6. Average stream flow during periods of release of effluent into a flowing stream = 7,175 cfs, based on information from the National Weather Service or Army Corps of Engineers for the Rock River.
b. Gaseous:
1. Number of batch releases = 401
2. Total time period for batch releases = 124,183 minutes
3. Maximum time period for a batch release = 24,268 minutes
4. Average time period for batch releases = 309.7 minutes
5. Minimum time period for a batch release , 28 minutes
6. Abnormal Releases:
a. Liquid - None L. Gaseous - Steam Generator Replacement Project related ground level release data are listed in Attachment B. Dose attributed to these releases is included in dose ca.culations.

ADDENDUM A. There were no major changes or modifications to the PCP, or to any liquid gaseous or solid redwaste treatment systems for this period.

B. Error Analysis The following is an estimate of the errors associated with effluent monitoring and analysis. The estimate is calculated 'asing the square root of the sum of the squares methodology.

1. Gaseous Effluents Sampling error. 1 to 3.5%

Calibration error. 10%

Counting Statistics error = 5%

Vent Stack Flowrates error = 1,5%

Total error. 11 - 12%

2. Liquid Effluents Sampling error = 1%

Calibration error = 10%

Sample volume error = 1%

Discharged volume error. 2%

Total error = 10%

3. Waste Resin

! Sampling error = 5%

Counting Statistics error = 7%

Weight error = 1%

Volume error- 5%

Total error = 10%

4. DAW Counting Statistics arror= 7%

Calibration error = 10%

Weight error = 2%

Total error 12%

4 C. Mateorological end environmental impact information is reported in tha Station Annual Radiological Environmental Op3 rating Rsport as required by Technical Specifications 6.9.1.6.

D. No limits were exceeded in liquid hold up tanks as scated in Technical Specifications 3.11.1.4 or in waste gas decay tanks as stated in Technical Specifications 3.11.2.6.

E. There were no irradiated fuel shipments during this period.

F. There were no elevated releases. All releases are considered vent or ground level releases.

G. The Offsite Dose Calculation Manual (ODCM) was revised in February of 1997 The revision is another step in implementing a uniform radiological effluent monitoring program (REMP) consistent among all Commonwealth Edison sites. The primary changes include reducing the frequency with which iodine cartridges are changed out from the eight (8) environmental monitoring stations from weekly to bi-weekly, and adding a third groundwater monitoring well sampling locatiori which is downgradient from Byron Station.

The site specific portion of the ODCM was revised in October of 1997 The revision reflected updated sampling locatiers based on a 1997 survey performed using a global positioning syatem. Additionally, surveillance requirements for the newly constructed Old Steam Generator Storage Facility were added. The changes do not affect the level of safety of the plant or affect the dose to the public or environment. A copy of the latest revision of the ODCM was submitted to the NRC under a separate cover by Cored's, Health Physics Support Dept.

H. Attached are the Offsite Dose Calculations for January through Decemorr of 1997.

RADIOACTIVE EFFLUENT RELEASE REPORT STEAM GENERATOR REPLACEMENT PROJECT RELATED GROUND LEVEL RELEASES During the Steam Generator Replacement Project (SGRP) several new effluent pathways were created to support the removal and installation of Steam Generators (S/Gs)in Unit 1 Containment. Approximately 63 uCi of particulate activity was calculated to have been released via SGRP related ground level effluent pathways during 1997, using conservative assumptions. No radioiodines were identified at any effluent sampling point during the course of the project.
