3.0 GASEOUS EFFLUENTS The gaseous radwaste effluents from WNP-2 were released in a continuous mode.
There are three (3) release points at WNP-2:
l.
Main Plant Vent - mixed mode release 2.
Turbine Building - ground level release 3.
Radwaste Building - ground level release There were no batch or abnormal releases of gaseous effluent during the third and fourth quarters of 1984.
Monitoring and sampling of the gaseous effluents were performed according to plant procedures.
The setpoi nts for the environmental radiation monitors were set as described in the ODCM.
The gaseous source terms from each release points are listed in Table 3-1 to 3-3.
Table 3-4 is a summation of the total releases of gaseous efflu-ents from WNP-2 plus the average release
- rate, gross alpha activities and the estimated total error associated with the measurements of radio-activity in the gaseous effluents.
The method of calculating the total estimated error associated with the gaseous effluent measurements is similar to the one described in Section 2.0 (Liquid Effluents).
The error estimates were performed on the gas grab sample, volume determination, flow rates, gas analysis by gamma spectrometry, air monitoring flow, calibration error of the gas analyzer detectors, and beta scintillation readings.
The final error was calculated to be 36% at the 95% confidence level.
In Table 3-4, the "Percent of Technical Specification Limit" calculations were based on the offsite exposure.
For the noble gases, dose to the whole body was 6.0 E-02 mrem for the third quarter and 1.8 E-02 mrem for the fourth quarter.
The maximum organ dose from the noble gases was 1.1 E-01 mrem for the third quarter and 3.6 E-02 mrem for the fourth quarter.
The maximum whole body dose due to Iodines and particulates was 6.3 E-02 mrem for the third quarter and 6.9 E-Ol mrem for the fourth quarter.
