April 29, 1999 U. S. Nuclear Regulatory Commission ATTN: Document Control Desk Washington, D.C. 20555-0001 Braidwood Station, Units 1 and 2 Facility Operating License Nos. NPF-72 and NPF-77 NRC Docket Nos. STN 50456 and STN 50-457 Subject :

1998 Radioactive Effluent Release Report The attached document includes the Radioactive Effluent Release Report for Braidwood Station. This report is being submitted in accordance with 1 OCFRSO.36a and Technical Specification 5.6.3, "Radioactive Effluent Release Report," and includes a summary of radiological liquid and gaseous effluents and solid waste released from the site from January 1998 through December 1998.

If you have any questions regarding this information, please contact Mr. T. W. Simpkin, Regulatory Assurance Manager, at (815) 458-2801, extension 2980.

2.

Maximum Permissible Concentration a., b.,c., For fission and activation gases, iodines, and particulates with half-lives greater than 8 days, allowable release limits are calculated by solving equations IO.

1 and 10.2 from the Offsite Dose Calculation Manual.

d.

For liquid effluents, allowable release limits are calculated by solving equations 10.3 and 10.4 from the Offsite Dose Calculation Manual.

3.

Average Energy T h e average gamma energy for the Braidwood noble gas waste streams was 0.745 MeV for Unit 1 and 0.222 MeV for Unit 2. The average beta energy for Braidwood noble gas waste streams was 0.306 MeV for Unit 1 and 0.153 MeV for Unit 2.

4.

Measurements and Approximations o f Total Radioactivity

a.

Fission and Activation Gases:

b.

lodines:

C.

Particulates:

Containment batch releases are analyzed for noble gas and tritium before being discharged by gamma isotopic and scintillation, respectively. Gaseous decay tanks are analyzed for noble gas before being discharged by gamma isotopic. Released activity is calculated using volume o f release, which is determined by change in tank or containment pressure.

The Auxiliary Building ventilation exhaust system is continually monitored for iodines and particulates. These samples are pulled every 7 days and analyzed by gamma isotopic. The particulate samples are also analyzed quarterly for gross alpha. Noble gas and tritium grab samples are pulled and analyzed weekly by gamma isotopic and scintillation, respectively.

The average flow at the release points are used to calculate the curies released.

d.

Liauid Effluents The liquid release tanks are analyzed before discharge by gamma isotopic and for tritium. A representative portion o f this sample is saved. This is composited, every 3 1 days, with other discharges that occurred and is analyzed for tritium and gross alpha. T h e batch composites are composited quarterly and sent to a vendor for Sr-89/90 and Fe-55 analysis. Circulating Water Blowdown, Condensate Polisher Sump and Waste Water Treatment are analyzed weekly by gamma isotopic and for tritium. These weekly samples are composited quarterly and sent to a vendor for Sr-89/90 and Fe-55 analysis.

The tank volumes and activities are used to calculate the curies released for the liquid release tanks. The total volume o f water released and the activity is used to calculate the diluted activity released at the discharge point from batch discharges.

e.

Less than the lower limit o f detection (<LLD).

Samples are analyzed such that the Technical Specification LLD requirements are met.

When a nuclide is not detected during the quarter then <LLD is reported.

1.

There were no changes to the Braidwood Station Process Control Program in 1998.

2.

There were no changes to the installed liquid, gaseous, or solid radwaste treatment systems in 1998.

3.

There were no liquid holdup tanks or gas decay tanks which exceeded the limits addressed in the ODCM-R E T S.

4.

Pursuant to ODCM-RETS Section 12.6.2, the following is an explanation as to why the inoperability o f liquid or gaseous effluent monitoring instrumentation was not corrected within the time specified in ODCM-RETS:

a.

No liquid or gaseous effluent monitoring instrumentation was inoperable longer than the time specified in ODCM-RETS.
