1. Regulatory 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 mradlyear

b. todine: (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 / quarter; 3 mrem / year Organ = 5 mrem / quarter; 10 mrem / year

e. Total Effective Dose Equivalent 10CFR20 TEDE = 100 mrem / year 1

2. Maximum Permissible Concentration

)

a. Fission and Activation Gases: 10CFR20 Appendix B Table 2

b. lodine: 10CFR20 Appendix B Table 2

c. Particulates: 10CFR20 Appendix B Table 2

d. Liquid Effluents: 10CFR20 Appendix B Table 2

3. 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 calculation utilize historical data and assign an isotopic mix which is representative of normal vent stack isotopics.

b. Particulate, Tritium and lodine 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 tntium 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 !cs6 than the lower kmit of detection (<LLD) are reported in units of Ci/ml unless otherwise noted. All LLD values are listed in Attachment A.

5. Batch Releases:

a. Liquid:

1. Number of batch releases = 258

2. Total time period for batch releases = 18,063 minutes

3. Maximum time period for a batch release = 331 minutes

4. Average time period for a batch release = 70 minutes

5. Minimum time period for a batch release = 7 minutes

6. Average stream flow during periods of release of effluent into a flowing stream

= 209 cms, based on information from the National Weather Service or Army Corps of Engineers for the Rock River, b Gaseous:

1. Number of batch releases = 295

2. Total time period for batch releases = 136,990 minutes

3. Maximum time period for a batch release = 40,870 minutes

4. Average time period for tetch releases = 464.4 minutes

5. Minimum time period for a batch release = 1 minute

6. Abnormal Releases:

a. Liquid - None

b. Gaseous Steam Generator Replacement Project related ground level release data is listed in

! Attachment B. Dose attributed to these releases is included in dose calculations.

,, c. Gaseous - Unit 2 Refuel Outage related ground level release data is listed in Attachment C. Dose I attributed to these releases is included in dose calculations.

i ADDENDUM A. Changes to Radioactive Waste Process Control Program for 1998 were administrative.

Procedures were updated by removing references to the Radioactive Waste System known as stock. The system was not used at Byron Station. Operationally, the Process Control Program remains unchanged.

B. Error Analysis The following is an estimate of the errors associated with effluent monitoring and analysis. The estimate is calculated using 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%

(p:\99byltrs\990040 doc) Report Page 23 of 31 e

4. DAW Counting Statistics error = 7%

Calibration error = 10%

Weight error = 2% l l

Total error = 12%

C. Meteorological and environmental impact information is reported in the Station Annual Radiological Environmental Operating Report as required by Technical Specifications 5.6.2.

D. No limits were exceeded in liquid hold up tanks as stated in Technical Specifications 5.5.12 or in waste gas decay tanks as stated in Technical Specifications 5.5.12.

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. During the second quarter of 1998, surveillance OBRSR 11.k.3-1 was not completed.

Per the technical requirement manual, the building's interior sump is to be monitored for l liquid quarterly. The surveillance was performed during the first quarter of 1998. It was j not performed again until the third quarter. During the third quarter performance, the surveillance met all acceptance criteria.

H. The site specific portion of the Offsite Dose Calculation Manual (ODCM) was revised in November of 1998. These changes were primarily administrative in nature and were performed in order to dual reference applicable sections in the Technical Requirements I Manual and Technical Specifications which were renumbered as part of Amendment 106, to Byron Station's Technical Specifications. Additionally, the description of the Component Cooling Water monitor was moved from the Airbome Process Radiation Monitor section of the ODCM (Section 10.1) and placed in the Liquid Process Radiation Monitor section (Section 10.2), in order to retain consistency. Dairy BY-27 was removed l from the REMP sampling program and Figure 11-4, due to the dairy closing down and no samples being obtained from the dairy. No replacement dairy has yet been identified, however vegetation samples are being acquired to meet ingestion pathway 4 monitoring requirements. A copy of the latest revision of the ODCM was submitted to the NRC under a separate cover by Com Ed's Generation Support Radiation Protection Department.

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 12 uCi of particulate activity was calculated to have been released via SGRP related ground level effluent pathways during 1998, using conservative assumptions. No radioiodines were identified at any effluent sampling point during the course of the project.
