ZionSohltions LLC ZS-2015-0055: Zion Station Radioactive Effluent Release Report for 2014 Attachment 1- Supplemental Information

1. Regulatory Limits: The dose to a member of the public from direct radiation, liquid and gaseous effluents released from each unit to areas at or beyond site boundary shall be limited to the following:

a. Fission and Activation products:

i. Tech Spec Whole Body: 500 mrem/year ii. Tech Spec Skin: 3000 mrem/year

b. Particulates with half-lives > 8 days, tritium and Iodine:

i. Tech Spec Organ: 1500 mrem/year ii. I OCFR50 Organ: 7.5 mrem/quarter, 15 nrern/year

c. Liquid Effluents:

i. 10CFR50 Whole body: 1.5 mrem/quarter, 3 mrem/year ii. 10CFR50 Organ: 5 mrem/quarter, 10 mrem/year

d. Combined dose to real individual beyond controlled area:

i. 10CFR72 Whole body: 25 mrem/year ii. 10CFR72 Thyroid: 75 mrem/year iii. 10CFR72 Organ: 25 mrem/year

2. Effluent Concentration Limits (ECL): Limits used in determining allowable release rates or concentrations.

a. Gaseous Effluents: 10CFR20 Appendix B Table 2 Column 1.

b. Liquid Effluents: 10 X 10CFR20 Appendix B Table 2 Column 2.

3. Measurements and Approximations of Total Radioactivity.

a. Fission and Activation Products: 100% Kr-85 is assumed in calculations since other isotopes have decayed. Vent stack activity is continuously monitored for fission and activation gases.

b. Particulate releases are continuously monitored and samples collected and analyzed weekly for particulates and tritium. Particulate filters are sent to an independent lab for quarterly composite analysis. 2RIA-PR49 Unit 2 gaseous effluent release monitor was replaced during the time period of Dec. 18-Dec. 29.

During this time period particulate activity was continuously monitored and analyzed daily in each of the three areas feeding into Unit 2 vent stack (i.e. Unit 2 purge system, Aux. building, Fuel Handling Building). A separate composite was sent to an independent lab for composite analysis during quarter 4. Tritium activity in gaseous releases are calculated from the water evaporation of water in the spent fuel pool and water filled reactor cavities.

ZionSolutions LLC ZS-2015-0055: Zion Station Radioactive Effluent Release Report for 2014

c. Liquid effluents are continuously monitored and isotopic analysis performed weekly. Liquid batch releases are mixed and a representative sample taken and analyzed prior to batch release. A complete analysis of all liquid volumes was performed by an offsite laboratory to determine hard to detect nuclide activity. A conservative ratio to Co-60 was calculated for each hard to detect nuclide. Prior to each batch release, these scaling factors were used to calculate the concentration of these hard to detect nuclides.

d. Occupancy factors were used in determining direct radiation dose to the maximally exposed member of the public based on habits of a real individual in ES&H Technical Support Document 13-009 "Member of the Public Dose from All Onsite Sources."

4. Batch Releases:

a. Liquid:

1. There were 50 liquid batch releases in 2014

2. Total time period for batch releases: 1.35E+05 min.

3. Maximum time period for a batch release: 6.56E+03 min.

4. Average time period for batch release: 2.70E+03 min.

5. Minimum time period for a batch release: 8.07E+02 min.

b. Gaseous: There were no gaseous batch releases in 2014.

5. Abnormal Releases:

a. Liquid: There were no liquid abnormal releases in 2014.

b. Gaseous: There were no gaseous abnormal releases in 2014.

6. Gaseous and Liquid Waste Treatment Systems and Process Control Program Zion Station ODCM Section 12.7.4 requires major changes to the Gaseous and Liquid Waste Treatment Systems to be reported in the Annual Radioactive Effluent Release Report.

Zion Station ODCM Section 12.7.2 requires major changes to the Process Control Program(PCP) to be submitted in the Annual Radioactive Effluent Release Report.

The Waste Gas Hold-up System was permanently vented. In Zion's defueled configuration this system is no longer applicable.

In Zion's defueled configuration, the charcoal iodine removal system is no longer applicable.

Due to radioactive decay and no means of production, radioactive iodine is not a concern at Zion.

7. Limiting Conditions of Operation (LCOs)

ZionSolutions LLC ZS-2015-0055: Zion Station Radioactive Effluent Release Report for 2014 Zion Station ODCM Section 12.7.2 requires explanation as to why the inoperability of liquid or gaseous monitoring instrumentation was not corrected within the time specified in the ODCM to be submitted with the Annual Radioactive Effluent Release Report.

Unit 2 Vent Stack 2RIA-PR49 SPING monitor had an electronic malfunction. The mechanical portion of the SPING monitor was still operating normally and still maintaining a representative sample of Unit 2 gaseous effluent, thus the normal pathway and mechanical components were used to perform the daily surveillances required for inoperable radiation monitor. ODCM section 12.2.2 requires the system be restored to operational status or a station review conducted to determine the course of action to restore the gaseous effluent radiation monitor to operable status. No repair parts were able to be found to repair the electronics of the SPING unit and no replacement was found to be available as the Eberline SPING radiation monitor is no longer manufactured nor supported causing Zion Station to perform surveillances from Nov. 11 to Dec. 29 (49 days). A station review was conducted and the course of action decided upon to restore the radiation effluent monitor to operable status was to replace the SPING unit that monitors Unit 2 vent stack with a new radiation monitor identical to the one currently used monitoring Unit I vent stack. The radiation monitor was replaced and is working properly. Attachment 8 is the summary of the review conducted and the actions taken to restore system operation.

8. Liquid Holdup Tanks and Gas Storage Tanks Zion Station ODCM Section 12.7.2 requires a description of events leading to liquid holdup tanks or gas storage tanks exceeding technical specification limits to be included in the Annual Radioactive Effluent Release Report.

The contents of the six gas decay tanks have been sampled and determined to have negligible activity. The Gas Decay Tanks have been abandoned in place.

No liquid holdup tanks exceeded the limits of Permanently Defueled Technical Specifications 5.6.3 during 2014.

9. Offsite Dose Calculation Manual (ODCM)

Changes to the ODCM and Process Control Program are required by Zion Station Permanently Defueled Technical Specification 5.6.1, and ODCM Section 12.6.3 to be submitted as part of, or concurrent with, the Annual Radioactive Effluent Release Report.

a. ODCM Revisions: There were no major changes to the ODCM in 2014

b. Process Control Program(PCP): There were no major changes to the PCP in 2014.

10. Switchyard Area The switchyard is an onsite area that is monitored for direct radiation dose. Access to the site is controlled by Commonwealth Edison and is not accessible to members of the

ZionSolutions LLC ZS-2015-0055: Zion Station Radioactive Effluent Release Report for 2014 general public. The dose limits for this area are regulated differently than the general offsite dose areas and comply with 10CFR20 annual dose limit of 100 mnrem/year. ES&H TSD 13-009 lists the evaluation performed to determine habits of the real individual working in the switchyard and are calculated to be occupied no more than 2088 hour0.0242 days 0.58 hours 0.00345 weeks 7.94484e-4 months s/year.

EXECUTIVE

SUMMARY

A review of 2014 effluent data indicates that the activity released from the station was far below any regulatory limit. There was no noble gas released in 2014. This trend can be attributed to the shutdown of both units since late September 1997.

I Introduction The purpose of the meteorological program being conducted at the Zion Station site is to provide information sufficient to assess the local weather conditions and to determine the degree of atmospheric dispersion of airborne radioactive effluent from the station.

The meteorological tower is 250 ft. high and is instrumented at two levels. Wind speed and direction are measured at 35 ft. and 250 ft. Ambient temperature is measured at 35 ft. Differential temperature, referenced to 35 ft., is measured at 250 ft. Dew point temperature is measured approximately ten feet from the tower at an elevation of 5 ft.

Precipitation is measured by a rain gauge located on the roof of the meteorological shelter building.

Joint frequency stability wind rose tables of wind direction, wind speed, and stability are routinely tabulated from hourly measurements. The quarterly and annual tables are included in this report.

Descriptions of the instruments and recorders are given in Section 3 (Data Acquisition) of this report. Data reduction and processing are described in Section 4 (Data Analysis).

The results given in Section 5 of this report include modeled maximum whole body doses, skin doses, organ doses based upon airborne releases, and site meteorology.

3. Data Acquisition Wind speed is measured with Teledyne Geotech model 1564 sensors and wind direction is measured with Teledyne Geotech model 1565 sensors. The wind speed sensors have a starting speed of 0.63 mph (0.28 mps), a range of 0 to 100 mph (0 to 44.7 mps), and a system accuracy of +1%. The wind direction sensors have a threshold speed of 0.7 mph (0.31 mps), a range of 0 to 5400, and a system accuracy of +50.

Ambient and differential temperatures are measured with RDF model 23789-4 sensors, and dew point temperature is measured with a Foxboro model 2781-18-CGN dewcell.

Ambient temperature is measured within the range of -40 to 120OF (-40 to 48.91C) with an accuracy of +0.50 F (+0.30C). Differential temperature is measured within the range of

-10 to 30°F (-5.6 to 16.70C) with an accuracy of +0.18 0 F (+0.100%), and dew point temperature is measured within the range of -40 to 120OF (-40 to 48.90C) with an accuracy of +2.7 0 F (+2.0°C). Precipitation is measured with a Climatronics model 100097 rain gauge. Precipitation is measured in increments of one one-hundredth of an inch with a system accuracy of +0.01" (+0.25mm).

Instrument types and locations are summarized in Table 1.

The meteorological data are collected and stored by a Microtel 4.0 data acquisition system. The Microtel measures the analog voltages of the instruments and records the digital equivalent within the range of 0 to +1 volt. The Microtel has the capability of storing 24 hours2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months of minute data and one week of hourly data. Data are obtained from the Microtel by a direct dial telephone hookup to an in-house computer system. Data are sampled every second.

As a backup to the Microtel, data are also recorded with a Johnson Yokogawa Corp. digital recorder (JYC DA100 data acquisition unit and Contec IPC-PT/M300(PC)WOU PC). Data are sampled every 10 seconds.

Data logger information is summarized in Table 2.

4. Data Analysis The Zion Microtel is routinely interrogated to obtain hourly average data. The data are then stored in the meteorological data-base and listings of the data are generated. The data listings are examined by qualified personnel and any apparent problems are brought to the attention of the Project Manager or Meteorological Technician and the Instrument Maintenance staff.

Hourly values of wind speed, wind direction, ambient temperature, differential temperature, dew point temperature, and precipitation are obtained through measurements taken at the site. The standard deviation of wind direction (sigma) is derived. The wind direction variation is described in terms of the standard deviation of the direction about the mean direction. The Microtel computes an hourly value of wind sigma by taking the Root-Mean-Square (RMS) of the four quarter-hour wind sigma values. The quarter-hour wind sigma values are calculated directly from the one second wind direction samples during the 15 minute period.

The data base files are edited approximately once a week. Missing Microtel values are replaced with recorder values, when available. Invalid data are deleted from the data-base.

Murray& Trettel, Inc. 6oo FirstBank Drive, Suite A Palatine,Ilinois 6o067 (847) 963-9000

6 When an hourly value is missing or invalid, the numeral 999 is entered into the computer data file in the appropriate location. When the wind direction changes substantially relative to its short term fluctuations, the numeral 888 can be entered into the wind sigma location to indicate shifting winds. When the wind blows with velocities near the sensing threshold of the instrument, the numeral 777 can be entered into the wind direction, wind speed, and wind sigma locations to indicate light and variable winds.

A professional meteorologist reviews the data, calibration findings, equipment maintenance reports, and other information and determines which data are valid. Only the valid data are retained in the data base.

As a quality control measure, a monthly comparison is made of Microtel and digital recorder data. An investigation is made into the reasons for any significant differences between the sets of values.

Joint frequency stability wind rose tables of hourly data measured at the site are generated. These tables indicate the prevailing wind direction, wind speed, and stability classes measured during the period of observation as well as the joint frequencies of occurrence of the wind direction, wind speed, and stability classes. The values are also used as input to the atmospheric transport and diffusion models. Wind direction, wind speed, and stability classes are given in Tables 3, 4, and 5.

9 The following two programs were used to calculate doses resulting from radioactive releases:

1. XOQDOQ: Computer Program for the Meteorological Evaluation of Routine Effluent Releases at Nuclear Power Stations (NUREG/CR-2919).

The program is based on the theory that material released to the atmosphere will be normally distributed (Gaussian) about the plume centerline. A straight-line trajectory is assumed between the point of release and all receptors.

The program implements the assumptions outlined in Section C of NRC Regulatory Guide 1.111. In evaluating routine releases from nuclear power plants, it primarily is designed to calculate annual relative effluent concentrations, X/Q values and annual average relative deposition, D/Q values.

Output from the XOQDOQ program is used as input to the GASPAR program.

2. GASPAR II: A Code System for Evaluation of Radiological Impacts Due to the Release of Radioactive Material to the Atmosphere During Normal Operation of Light Water Reactors (NUREG-0597).

GASPAR is a program written for the evaluation of radiological impacts due to the release of radioactive material to the atmosphere during normal operation of reactors. The GASPAR code implements the radiological impact models of NRC Regulatory Guide 1.109, Revision 1, for atmospheric releases. The program is used to estimate the maximum individual doses at selected locations in the vicinity of the plant.

5. Results 5.1 Instrument Maintenance The maintenance program followed during 2014 was composed of routinely scheduled visits and equipment repairs. Routine site visits were made to inspect the sensing and recording systems for proper operation. In addition, routine maintenance and calibration checks of all tower-mounted and ground level equipment were performed every 4 months. A description of the calibration and field procedures is found in the Murray and Trettel, Inc. "P1009 Procedures Manual" (October 2013).

In February, a malfunctioning rain gauge was repaired. Also in February, an obstruction light on the tower was replaced.

In March, the 35 ft. wind speed sensor was replaced due to bad readings.

In April, the 250 ft. wind direction wind vane was replaced due to damage.

In May, the 250 ft. wind direction sensor and signal conditioning card were replaced due to suspected bad readings. The removed sensor was later bench tested and was found to be in proper working order. Also in May, the annual tower inspection was performed.

In June, new mounting brackets for the temperature assemblies were installed. This was preventative maintenance due to bracket failures seen at other sites.

In October, bad readings on the 250 ft. wind direction were investigated. The cross arm was replaced due to a stripped out set screw. The wind direction sensor was also replaced. The bad readings caused some data loss.

In November, a damaged heat lamp assembly at the 250 ft. level was replaced.

No other significant problems were encountered with the equipment, and at the end of the year, no problems were evident at the site.

ZionSolutions LLC ZS-2015-0055: Zion Station Radioactive Effluent Release Report for 2014 Attachment 6 - Errata data There are no errata corrections from prior years reports in 2014

ZionSolutions LLC ZS-2015-0055: Zion Station Radioactive Effluent Release Report for 2014 Attachment 7 - Changes to Zion Station Liquid Radwaste System Summary: Changes to the ODCM to support the design changes to the liquid radwaste system were performed in 2013. These design changes were submitted in the 2013 Annual Radioactive Effluent Release Report. The physical changes to the system were implemented in 2014.

The changes made to the system utilize most of the in-place piping and tanks, two pillow tanks have been installed to support processing of liquid waste through the pre-existing filters and demineralizers. There are no changes made to the methodology or equipment used to reduce radioactive effluent concentration in liquid effluent. Figure 1 shows the simplified one line diagram of the system.

Overview of system operation: Liquid radwaste is stored in the 498,000 gallon Refueling Water Storage Tank (RWST) (pre-existing). From the RWST, the liquid is transferred to one of three 128,000 gallon Hold Up Tanks (HUT)(pre-existing). When a batch release is desired to be performed, water from the HUTs are pumped to one of two 25,000 gallon pillow tanks (newly constructed). Once in the pillow tanks, water is sent through the charcoal filters and demineralizers to reduce the effluent concentration and other particulates that may be present in the water. Demineralizer inlet and outlet sampling is performed to test the effectiveness of the demineralizer and predict when filters and resins will need to be changed. If desired, from the pillow tanks, water may be sent through the demineralizers multiple times. After sending the water through the demineralizers, the water is then sent to one of two 25,000 gallon Lake Release Tanks (LRT) (pre-existing and previously named Boric Acid Tanks). Water in the LRTs is then recirculated 3 times within a 12 hour1.388889e-4 days 0.00333 hours 1.984127e-5 weeks 4.566e-6 months period per ANSI standards for representative sampling. A sample is drawn, isotopically analyzed and stored for quarterly composites from an offsite laboratory. The analyzed samples include hard to detect nuclides that may be present scaled into the isotopic mixture and the results of the analysis compared with effluent release limits per 10CFR20 table 2 column 2 prior to release. If the water fails the comparison, it is sent back to the RWST for re-processing. Satisfactory results allow for the discharge of the liquid.

The liquid effluent monitor is verified functional and water is discharged at the rate calculated based on dilution flow into the effluent discharge piping (pre-existing). If the liquid effluent monitor alarms, the downstream valve closes to stop the release prior to reaching the discharge point and a notification is sent to the guard-it dialer notifying operations personnel of the event.

ZionSolutions LLC ZS-2015-0055: Zion Station Radioactive Effluent Release Report for 2014 Waste Water Treatment System Drawing Figure 1 All applicable changes have been evaluated in accordance with 10CFR 50.59 by ANSI qualified technical review personnel. Doses to members of the public have been evaluated during system design to ensure that the system continues to maintain doses to the public and workers are as low as reasonably attainable and well within limits.

ZionSolutions LLC ZS-2015-0055: Zion Station Radioactive Effluent Release Report for 2014 Attachment 8 - Station Review and Reason for inoperable monitor surveillances conducted > 30 days.

Station Review Date: 12/3/14 To: Station Review Committee

Subject:

2RIA-PR49 Channel 1,5 Inoperable >30 days per ODCM Table 12.2-3 Surveillance 10, 11 Supporting Documentation: TR-032-2014 After an exhaustive search was performed, it is determined the SPING monitor being used to monitor effluent from Unit 2 vent stack is unable to be repaired due to repair parts no longer available. The SPING unit being in place as 2RIA-PR49 is no longer manufactured by Eberline and no repair parts are supported. The SPING unit that was in use for Unit 1 vent stack parts had already been salvaged and used for repairs in the past. Other stations have been contacted for salvage parts and various parts dealers have been contacted for the parts to repair the SPING unit. None were found. To have an effluent radiation monitor built to the design required, manufacturers ask for an 18 month lead time to build an effluent monitor for Zion Station. TR-032-2014 has determined that installing an AMS-4 such as the one in Unit 1 will meet the requirement for gaseous effluent radiation monitoring, and this system can be installed within 4 weeks; however, Zion will exceed the 30 days prescribed to restore normal effluent monitoring and this station review satisfies the ODCM requirement to determine the course of action to restore effluent monitoring.

Channel I particulate: This change was previously evaluated and will be established by using an AMS-4 similar to the operation of 1RIA-PR49 that is currently in place. This change will be implemented now instead of after all fuel is removed from Spent Fuel Pool.

Channel 5 noble gas: Several alternate methods of re-establishing continuous noble gas monitoring were examined. Each of the three alternate methods required an engineering change, and physical reconfiguration of one form or another to establish a suitable monitoring flowpath.

Two of the methods for noble gas monitoring would require evaluation time that would place the timeline of re-establishing noble gas monitoring past January 31, 2015 or later and thus the method presented here is the only reasonable method of re-establishing continuous noble gas monitoring while fuel is still present.

Technical Review summary of Channel 5 noble gas method: Engineers of Thermo-Scientific were contacted to determine if the AMS-4 particulate monitor could also be used to monitor noble gas concurrently with particulate. The contact personnel responded that it was possible, using correction factors and efficiencies for Kr-85 instead of Sr-90. The alarm setpoint will be extremely low since the detector volume is setup for particulate. However this is feasible since there has been less than minimum detectable particulate effluent. This single setpoint based on noble gas will also satisfy the particulate alarm setpoint. Once all fuel is removed, the setpoint can be changed to reflect only the particulate setpoint.

The Station Review Committee concurred with the proposed corrective actions. Corrective actions were completed on December 29, 2014 and the Unit 2 vent stack effluent radiation monitor was placed back in service.
