DRESDEN NUCLEAR POWER STATION UNITS 1,2 AND 3 EFFLUENT AND WASTE DISPOSAL ANNUAL REPORT ,

January Through December 1997 l DOCKET NUMBERS: 50-010/50-237/50-249

1. Regulatory Limits
a. For Noble Gases I Dose Rate
1) less than 500 mrem / year to the whole body.
2) Less than 3000 mrem / year to the skin.

Dose Gamma Radiation

1) less than or equal to 5 mrad / quarter
2) less than or equal to 10 mrad / year Beta Radiation
1) Less than or equal to 10 mrad /quaner
2) lxss than or equal to 20 mrad / year b,c. For Iodine-131, for hxline-133, and for all radionuclides in particulate form with half-lives greater than 8 days.

Dose Rate

1) less than 1500 mrem / year Dose ,

i

1) less than or equal to 7.5 mrem / quarter to any organ.
2) less than or equal to 15 mrem / year to any organ.
d. For Liquid
1) less than or equal to 3 mrem to the whole body during any calendar quarter.
2) less than or equal to 10 mrem to any organ during any calendar quarter.

less than or equal to 6 mrem to the whole body during any calendar year.

J

3) >
4) less than or equal to 20 mrem to any organ during any calendar year.
2. Maximum Permissible Concentiation
a. ,b. , c., For fission and activation gases, iodines and paniculates with half-lives greater than 8 days, allowable dose rates are calculated by solving equations 10.1 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.

l l 3. Average Energy he average energy of fission and activation gases was calculated for the gaseous effluents released from the site.

The average energy is based on the percentage of each fission gas nuclide present and its average energy per l disintegration (E in MeV/ dis) for gamma and beta emissions separately.

1 Eo4m4 = 6.31E4)1 MeV/ dis Enn4 = 4.69E-01 MeV/ dis

4. Measurenents and Approximations of Total Radioactivity
a. Fission and Activation Gases:
b. Iodines:
c. Particulates:

ne Chimneys and Reactor Building Vent are continually monitored for iodines and particulates. These samples are pulled weekly and analyzed by gamma isotopic. He particulate filters are composited and sent to a vendor for gross alpha, Sr-89-90 and Fe-55 analysis. Noble gas grab samples are pulled and analyzed by gamma isotopic weekly. Tritium samples are pulled and analyzed monthly.

He average flow at the release points are used to calculate the curies released. For the Unit 1 Chimney the design basis flow is used to calculate curies released.

d. Liquid Effluents l

Re river discharge tanks are analyzed before discharge by gamma isotopic. A composite representative portion of this i sample is saved. This is composited with other discharges that occurred during the sample period. De composite is sent to a vendor for gross alpha,11-3, Fe-55, Sr-89-90 analysis.

The tank volumes and activities are used to calculate the diluted activity released at the discharge point from batch discharges.

e. Less than the lower limit of detection ( < LLD)

Samples are analyzed such that the ODCM LLD requirements are nrt. When a nuclide is not detected then < LLD is reported.

f. Equipment out-of-senice No ODCM required effluent monitors were out of service for 30 or more continuous days in 1997.
g. Estimation of Data:

In November 1997 while the U2/3 Main Chimney SPING was being cahbrated, it was discovered that the mmple flow did not correspond to the flow calculated by the SPING . The measured flow through the SPING was 531/ min while the display was reading 70 1/ min (PIF D1997-07991). This is non conservative. It was assumed that inleakage started immediately following the previous cahbration (May 1996). Based on the ratio of the above flows, the concentration reported could be roughly 30% higher. In order to compensate for the lower concentration, the concentrations, pCi/cc, were conservatively multiplied by a factor of 1.5 for samples collected by the SPING.

A.1 In June,1994, elevated tritium levels were discovered in the on-site storm sewers. The highest storm drain concentration, 1.11E+ 03 pCi/1, from the 3rd quarter was used for both the 1st and 2nd half of 1997. The total activity released is based on an estimated typical discharge flow of 10 gallons per minute. An estimated 1.09E-03 Ci of 11-3 may have been released into the environment. Various storm sewer locations on-site are now periodically analyzed for tritium.

l i

l B.1 On March 18,1997 it was discovered that the Unit 3 Main Turbine had a gland seal leak which was allowing steam to enter the U3 Turbine Oil Reservoir. There is an exhaust fan on the reservoir which exhaust directly into the environment with no mcmitoring. It is unknown when the leak started. He leak stopped on March 27,1997 when the Unit was shutdown for a refuel outage. The gland seal was repaired. The following activity is estimated to have been released to the environment:

Co-60 4.85E+02 pCi Mn-54 5.50E+01 pCi Xe-135 9.40E + 01 Ci Xe-135m 3.07E+02 pCi B.2 The East Turbine Building Ventilation System was found to have a contaminated fan blade in 1996. This system is designed to pull air in from outdoors and ventilate non-Radiologically Posted Areas and then exhaust the air back into the environment. It is unknown when the fan blade become contaminated. Smears of the ductwork indicate the presence of Co-60, Ba-133 and Cs-137. An estimated 8.00E+00 Ci of Co-60,3.00E+00 pCi of Ba-133 and 5.00E+00 pCi of Cs- i 137 may have been exhausted into the environment for all of 1997. I B.3 he heating steam system has low level contamination present. During operation of the system, some steam is vented directly into the environment. Isotopic analysis of the condensate in the system indicate the presence of Co-60, Mn-54 and Cs-137. An estimated 2.00E-01 pCi of Co-60,1.60E+00 pCi of Mn-54 and 2.50E-01 pCi of Cs-137 may have been exhausted into the enviromnent for all of 1997. l

B.1 On September 4,1997 it was discovered that the gland seal on the Unit 3 hiain Turbine which had been repaired during the previous refuel outage was leaking again allowing steam to enter the U3 Turbine Oil Reservoir. There is an exhaust fan on the reservoir which exhaust directly into the environment with no monitoring. It is unknown when the leak resumed. The leak continued through the end of 1997 into 1998.

This release was attributed as an abnormal release in the first half of 1997 and the pCi values are not included in the 1997 second half totals.
