B. Maximum Permissible Concentrations

1. Gaseous Releases The RBS Radiological Effluents Technical. Specifications (RETS) for gaseous releases are based on the dose rate restrictions of 10CFR20, rather than the Maximum Permissible Concentrations (MPC) listed in 10CFR20 Appendix B, Table II, Column 1.
2. Liquid Releases The Maximum Permissible Concentration of radioactive materials in liquid effluents is limited by 10CFR20, Appendix B, Table II, Column 2. The MPC chosen is the most conservative value (i.e., the lowest) of either the soluble or insoluble MPC for each radionuclide.

C. Average Energy Not applicable to RBS RETS D. Measurements and Approximations of Total Radioactivity

1. Gaseous Effluents
a. Fission and Activation Gases Periodic grab samples are obtained from the Main Plant Exhaust Duct, Fuel Building Exhaust Vent and Radwaste Building Exhaust Vent. These samples are analyzed utilizing high resolution germanium detectors coupled to computerized pulse height analyzers. The sampling and analysis frequencies are described in Table 1. Sampling and analysis of these effluent streams provide noble gas radionuclide relative abundances which can then be applied to the noble gas gross activity and gross activity release rate to obtain nuclida specific activities and release rates. The noble gas gross activity released within a specific time period is determined by integrating the stack monitor release rate over the considered time period. A Xe-135 correlation factor (laboratory analysis derived sample activity concentration - monitor response in uCi/cc) of 0.136 was used for determining the total amount of noble gas activity released in the month of June. Prior to June, a correlation factor of 1.0 was used. If no activity was detected in the stack sample, the nuclide relative abundances of the last sample which indicated the presence of activity was utilized to obtain nuclide specific activities.

b. Particulates and Iodines Particulates and iodines are continuously sampled from each of the three release points utilizing a particulate filter and charcoal cartridge in line with a sample pump (stack monitor pump). These filters and charcoal cartridges are removed and analyzed in accordance with the frequencies specified in Table 1. Analysis is performed to identify and quantify radionuclides utilizing high-resolution germanium detectors coupled to computerized pulse height analyzers. Given the nuclide specific activity concentrations, process flow rate, and time which the sample covered; the nuclide specific activity released to the. environment can be obtained.

Due to the continuous sampling process, it is assumed that the radioactive material is released to the environment at a constant rate within the sampling period. Sr-89 and Sr-90 are quantitatively analyzed by counting the digested filter precipitate with a gas flow proportional counter. Gross alpha analysis is performed using a zinc sulfide scintillation counter.

c. Tritium Tritium grab samples are obtained from the three release points at the specified frequencies listed in Table 1 utilizing an acetone / water ice bath condensation collec-tion method. The collected sample is then analyzed utilizing a Liquid Scintillation Counter. Given the tritium concentration, process flow rate, and time period for which the sample is obtained, the tritium activity released to the environment can be determined. Due to the frequency of sampling, it is assumed that the tritium is released to the environment at a constant rate within the time period for which the sample is obtained.
2. Liquid Effluents Representative grab samples are obtained from the appropriate sample recovery tank and analyzed prior to release of the tank in accordance with the frequencies listed in Table 2.

Analysis for gamma emitting nuclides (including dissolved and entrained noble gases) is parformed utilizing a high resolution germanium detector coupled to a computerized pulse height analyzer. Tritium concentration is determined i utilizing a Liquid Scintillation Counter. Sr-89 and Sr-90 are quantitatively analyzed by counting the precipitate with a gas flow proportional counter. Fe-55 is counted with a Liquid Scintillation Counter after digestion of the iron. Gross alpha analysis is performed using a zinc sulfide scintillation counter. Given the nuclide specific activity concentration and total volume of the tank that was released, the activity of each nuclide released to the environment can be determined. 7 of 29

2. Gaseous Primary Containment /Drywell purges are considered gaseous batch releases. Purges are directed through the Main Plant Exhaust Duct prior to release to the environment and are therefore monitored by the Main Plant Exhaust Duct stack monitor. For purposes of this report, a purge is in effect only when purge inlet valves *A0V-128 and *A0V-166, and purge outlet valves *A0V-165 and *A0V-123 are open. Containment venting (i.e., for pressure reduction) is not considered a release due to the short time duration of each venting period and limited motive force of the release. Due to logistical considerations, all releases through the Main Plant Exhaust Duct for the duration of the purge are'*onsidered c as part of the batch.

b. Total activity released  : O Curies On January 14, 1986 at 1624 hrs, radioactive liquid discharge no. 86-0044 was initiated without the radwaste liquid effluent monitor (1RMS-RS107) sample pump being started. At 2150 hours the radwaste operator terminated the release and observed that the sample pump was not running. The entire contents of recovery sample tank 1LWS-TK4A had been discharged without the required radiation monitor which provides an automatic termination of the release at a preset activity concentration !!ICH ALARM limit. Samples taken before the incident indicated the presence of only tritium. No gamma-emitting radionuclides were detected in s ampics taken before and after the discharge. A total of 1210.11 uCi oi tritium was discharged to the environment during this unmonitored release. An investigation proved that the sample pump was never started due to procedural inadequacies and miscommunication between operators.

All discharges were terminated until the required procedure changes and training were conducted. These changes require the operators to initial the permit indicating initiation of sample pump operation and to physically verify the operation of the pump. In addition, a modification request was initiated to provide automatic closure of discharge isolation valve ILWS-A0V257 in the event of a low sample flew rate signal from the 1RMS-RE107 monitor. There were no safety and health conseqtences to the public as a result of this event as indicated by samples taken before and after the discharge.

           .On April   2,   1986, it was discovered that air was exiting the Main Steam Tunnel blow out panels on top of the Auxiliary Building roof (170' elevation). Since this flow of air represented a possible pathway for unmonitored radioactive releases, air samplers were positioned in front of these panels      On April 15, analysis of air samples indicated the presence of radioactive material in the air exiting the panels.             It is estimated that approximately 19 uCi of particulate (T                 >8 days) and radioiodine 1/2 activity were released from the blow out panels from 4/2/86 through 6/30/86. These releases coincided with reactor power levels of at least 50 percent or greater. No activity was detected in air sampics when the unit was shut down. A Modification Request was initiated on 6/6/86 to prevent further releases.        The field work for .this Modification Request is scheduled to be completed by 9/1/86.
