River Bend Station 2014 Regulatory Guide 1.21 Report Page 8 of 91 B. Effluent Concentration Limits

1. Gaseous Releases The concentrations of radioactive gaseous releases are based on the dose rate restrictions in RBS Technical Requirements, rather than the Effluent Concentration Limits (ECL) listed in 10CFR20 Appendix B, Table 2, Column 1.

2. Liquid Releases The Effluent Concentration Limits of radioactive materials in liquid effluents are limited to ten times 10CFR20, Appendix B, Table 2, Column 2.

C. Measurements and Approximations of Total Radioactivity

1. Gaseous Effluent

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 using high purity germanium detectors coupled to computerized pulse height analyzers. The sampling and analysis frequencies are described in Table 1F.

Sampling and analysis of these effluent streams provide noble gas radionuclide relative abundance that can then be applied to the noble gas gross activity and gross activity release rate to obtain nuclide 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. If no activity was detected between the stack grab sample and a significant increase in hourly averages was recorded, the nuclide relative abundance of the last sample (or the last similar event), which indicated the presence of activity, was used to obtain nuclide specific activities. Correction factors for the monitors are derived and applied for each sampling period whenever noble gas radionuclides are detected in the effluent stream.

River Bend Station 2014 Regulatory Guide 1.21 Report Page 9 of 91

b. Particulate and Radioiodine (1-131 & 1-133)

Particulates, Iodine-131 and Iodine-133 are continuously sampled from the three release points using 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 1F. Analysis is performed to identify and quantify radionuclides using high purity germanium detectors coupled to computerized pulse height analyzers. Given the nuclide specific activity concentrations, process flow rate, and duration of the sample, 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. Strontium-89 and Strontium-90 (Sr-89 and Sr-90) are quantitatively analyzed by counting by gas flow proportional counting. Gross alpha analysis is performed using a zinc sulfide scintillation counter.

c. Tritium Tritium grab samples are obtained from the three gaseous release points at the specified frequencies listed in Table IF using an ice bath condensation collection method. The collected sample is then analyzed using 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.

d. Carbon-14 (C-14)

C-14 release details are discussed in Section VI.

e. Nickel-63 No Nickel-63 was quantified in 2014.

River Bend Station 2014 Regulatory Guide 1.21 Report Page 10 of 91

2. Liquid Effluent 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 2E. Analysis for gamma emitting nuclides (including dissolved and entrained noble gases) is performed using a high purity germanium detector coupled to a computerized pulse height analyzer. Tritium concentration is determined using a liquid scintillation counter.

Strontium-89 and Strontium-90 are quantitatively analyzed by scintillation techniques (Cherenkov counting). Iron-55 is counted with a liquid scintillation counter after digestion of the iron. Gross alpha analysis is performed using a zinc sulfide scintillation counter. The activity of each nuclide released to the environment is determined from the nuclide specific concentration and total tank volume released.

D. Batch Releases

1. Liquid Effluents Batch releases and receiving stream flow from River Bend Station during the reporting period of January 1, 2014, through December 31, 2014 are shown in Table 2D.

The Mississippi River stream flow is obtained by averaging data from the U. S. Army Corp of Engineers website using flow gauge data at Tarbert Landing.

2. Gaseous Effluents There were no routine batch releases of gaseous effluents from River Bend Station during the reporting period of January 1, 2014, through December 31, 2014.

E. Abnormal Releases There were no liquid abnormal releases in 2014. The releases reported in the groundwater monitoring section are not expected to be detectable outside the site boundary.

There was one potential abnormal gaseous release.

River Bend Station 2014 Regulatory Guide 1.21 Report Page I11of 91 During rounds on 5/11/2014, an operator determined that the direction of airflow between the Turbine Building and C-Tunnel was from the Turbine Building into C-Tunnel, and the expected direction of airflow should be from C-Tunnel into the Turbine Building. The investigation revealed there was an inlet screen associated with the Normal Switchgear ventilation louver that was clogged contributing to the incorrect flow. Maintenance was performed on filters and louvers to correct the situation. In addition, future cleaning of the filters and louvers were combined into one preventative maintenance task.

The significance of air flowing from the Turbine Building into the C-Tunnel is the potential of an unmonitored release pathway due to the fact that the Turbine Building ventilation at the 67-foot elevation was positive with respect to the C-Tunnel. The C-Tunnel discharge is through the Normal Switchgear Building, which is not a monitored gaseous release point. It is not known for certain if activity was actually released via this building vent. Nevertheless a conservative estimate of the activity released and the potential worst case dose to a member of the public demonstrated that if the activity in C-Tunnel had been released from the Normal Switchgear Building for an entire year, any dose to the public would be a small fraction of the typical annual effluent dose. The estimated activity and the potential dose impact are reported in the Table 1 series.

F. Estimate of Total Error

1. Liquid The maximum error associated with sample collection, laboratory analysis, and discharge volume is collectively estimated to be:

Fission and Activation Products: + 14.2%

Tritium: + 14.2%

Dissolved and Entrained Noble Gases: + 14.2%

Gross Alpha Radioactivity: + 14.2%

2. Gaseous The maximum error (not including sample line loss) associated with sample flow, process flow, sample collection, monitor accuracy and laboratory analysis are collectively estimated to be:

Noble Gases: + 37.0%

River Bend Station 2014 Regulatory Guide 1.21 Report Page 12 of 91 lodines  : + 18.6%

Particulate: + 18.6%

Tritium: + 18.2%

3. Determination of Total Error The total error (i.e., collective error due to sample collection, laboratory analysis, sample flow, process flow, monitor accuracy, etc.) is calculated using the following equation:

ET= V((E1 )L + (E2)L +

where:

ET = total error El, E2 ...En = individual errors due to sample collection, laboratory analysis, sample flow, process flow, monitor accuracy, etc.

II. GASEOUS EFFLUENT

SUMMARY

INFORMATION Refer to the Table 1 series for the summation of gaseous releases. It should be noted that an entry of "O.OOE+00" Curie (Ci) or microcurie/second (uCi/sec) in this section indicates that the concentration of the particular radionuclide was below the Lower Limit of Detection (LLD) as listed in Table iF. Also, any nuclide not appearing in the tables was < LLD for all four quarters.

III. LIQUID EFFLUENT

SUMMARY

INFORMATION Refer to the Table 2 series for the summation of liquid releases. It should be noted that an entry of "O.OOE+00" Ci or uCi/mI in this section indicates that the concentration of the particular radionuclide was below the Lower Limit of Detection (LLD) as listed in Table 2E. Also, any nuclide not appearing in the tables was < LLD for all four quarters.

IV. SOLID WASTE Refer to Table 3, for Solid Waste and Irradiated Fuel Shipments.

River Bend Station 2014 Regulatory Guide 1.21 Report Page 13 of 91 V. RADIOLOGICAL IMPACT ON MAN (40CFR190)

An assessment (see summary below) was made of radiation doses to the likely most-exposed member of the public from River Bend and other nearby uranium fuel cycle sources (none within five miles). The annual (calendar year) dose or dose commitment to any MEMBER OF THE PUBLIC, due to releases of radioactivity and to radiation from uranium fuel cycle sources, shall be limited to less than or equal to 25 mrem to the total body or any organ, except the thyroid, which shall be limited to less than or equal to 75 mrem.

Carbon-14 (C-14)

The bounding annual dose from C-14 was calculated using guidance from Regulatory Guide 1.21, Revision 2, NUREG-0016, and the methodology in Regulatory Guide 1.109. The C-14 source term of 11 curies was taken from the site calculation PR(C)-359-3A, Gaseous Releases per NUREG-0016 Revision 1.

Carbon-14 does not have dose factors associated with standing on contaminated ground; therefore, no ground plane dose was calculated. There is no milk pathway within five miles of River Bend Station so this pathway is not evaluated. RBS does not take credit for decay in the X/Q. This calculation assumes the inhalation, meat and vegetation pathways are at the site boundary in the sector with the highest X/Q.

The dose from liquid effluents is not calculated as the dose contribution from C-14 is considered to be insignificant as indicated in Regulatory Guide 1.21, Revision 2.

According to EPRI 1021106, Estimation of Carbon-14 in Nuclear Power Plant Gaseous Effluents, 95% of the carbon released is in the form of carbon dioxide and this contributes the highest dose to man. The ingestion pathway, specifically vegetation, is the most likely route of intake for man. An assumption has been made for gaseous releases that plants obtain all of their C-14 from carbon dioxide.

Dose not including C-14:

Organ mrem Total Body 4.21E-02 Skin 2.60E-02 Thyroid 5.18E-02 Other Organ 4.22E-02 Bounding Dose from C-14 only:

Organ mrem Total Body 9.39E-01 Skin 0.OOE+00 Thyroid 9.39E-01 Other Organ (bone) 4.70E+00

River Bend Station 2014 Regulatory Guide 1.21 Report Page 14 of 91 In addition, an assessment of doses was made for members of the public due to their activities inside the site boundary. Parameters and assumptions used to make this determination can be found in Table 4. The results of the calculations can be found in Table 5. The maximally exposed member of the public was an employee staying at RBS during the week and is conservatively calculated to have stayed at least four days per week for 34 weeks. It should be noted that liquid effluent pathway dose was not considered since these individuals would not engage in activities that would allow exposure to this pathway.

VI. METEOROLOGICAL DATA See Tables 6 and 7 for the cumulative joint frequency distributions and annual average data for continuous releases. The meteorological recovery for 2014 was 98.5 %.

VII. RADIOACTIVE LIQUID EFFLUENT MONITORING INSTRUMENTATION OPERABILITY The minimum number of channels required to be OPERABLE as described in Table 3.3.11.2-1 of Technical Requirement 3.3.11.2 were, if inoperable at any time in the period January 1, 2014, through December 31, 2014, restored to operable status within the required time.

VIII. RADIOACTIVE GASEOUS EFFLUENT MONITORING INSTRUMENTATION OPERABILITY The minimum number of channels required to be OPERABLE as described in Table 3.3.11.3-1 of Technical Requirement 3.3.11.3 were, if inoperable at any time in the period January 1, 2014, through December 31, 2014, restored to operable status within the required time.

IX. LIQUID HOLD UP TANKS The maximum quantity of radioactive material, excluding tritium and dissolved or entrained noble gases, contained in any unprotected outdoor tank during the period of January 1, 2014, through December 31, 2014 was less than or equal to the 10 curie limit as required by Technical Specification 5.5.8.b.

River Bend Station 2014 Regulatory Guide 1.21 Report Page 15 of 91 X. RADIOLOGICAL ENVIRONMENTAL MONITORING There were no changes to the Radiological Environmental Monitoring Program during the reporting period January 1, 2014, through December 31, 2014.

XI. LAND USE CENSUS The Land Use Census for 2014 was conducted in accordance with procedure ESP-8-051, as required by the Technical Requirements Manual (TRM) (TR 3.12.2). The results of the Land Use Census will be included in the Annual Radiological Environmental Operating Report pursuant to Technical Specification 5.6.2. The attached Table 1 summarizes the results.

A garden census is not conducted pursuant to the note in the TRM 3.12.2 that allows the sampling of broadleaf vegetation in the highest calculated average ground-level D/Q sector near site boundary in lieu of the garden census.

The milk animal census identified no milk animals within 8 km (5 miles) of River Bend site. This information was verified by the County Agents from West Feliciana, East Feliciana and Pointe Coupee parishes.

No resident census changes were noted.

No locations were identified this period that would yield a calculated dose or dose commitment greater than those currently calculated in Requirement TSR 3.11.2.3.1.

The County Agents confirmed that there was no commercial harvesting of crawfish within the five-mile radius downstream of RBS. RBS conservatively uses the invertebrate pathway although not required by NUREG-0133 liquid dose factor methodology for fresh water nuclear power plants.

XII. OFFSITE DOSE CALCULATION MANUAL (ODCM)

There were no changes to the ODCM in 2014.

XIII. MAJOR CHANGES TO RADIOACTIVE LIQUID, GASEOUS, AND SOLID WASTE TREATMENT SYSTEMS Engineering performed a review of the Asset Suite database to evaluate non-administrative design changes completed or partially completed during 2014 involving the subject systems (i.e. changes classified as evaluations or nuclear

River Bend Station 2014 Regulatory Guide 1.21 Report Page 16 of 91 changes). These design changes were then reviewed to determine if there have been any major changes to the subject systems. The review was based on a major change being defined as a modification which affected the method of processing or the effluent from the system. Also, to be a "major change" the change must have affected the Updated Safety Analysis Report (USAR).

The Engineering Changes (EC's) to liquid, solid or gaseous radwaste systems implemented during this time period were:

EC-50174 TMOD ECN Rev. 0 - This was a change to reflect a new Engineering TMOD owner for TMOD EC-35300. TMOD EC-35300 was documented in the 2012 Annual Effluent Report input and determined that this change does not constitute a major change to either the liquid, solid or gaseous radwaste treatment systems.

The following TMOD ECNs were processed to provide changes to TMOD EC-41004. TMOD EC-41004 was documented in the 2013 Annual Effluent Report input and determined that this change does not constitute and major change to either the liquid, solid or gaseous radwaste treatment systems.

EC-54762 TMOD ECN Rev. 0 - This was a change to provide additional details regarding freeze protection methods for the remediation skid.

EC-50608 TMOD ECN Rev. 0 - This was a change to revise preventative maintenance statement in TMOD EC-41004.

EC-50177 TMOD ECN Rev. 0 - This was a change to provide a new Engineering TMOD owner for TMOD EC-41004.

EC-47305 TMOD ECN Rev. 0 - This was a change allowing a deviation from the provided requirements for hose installation in TMOD EC-45515. TMOD EC-45515 was documented in the 2013 Annual Effluent Report input and determined that this change does not constitute and major change to either the liquid, solid or gaseous radwaste treatment systems.

No EC was identified as being completed during this time period that modified any radioactive waste system major component such that the processing method or effluent was changed. Also no changes were identified affecting the method of processing solid, liquid or gaseous waste or the isotopic composition or the quantity of liquid, solid, or gaseous waste as described in the USAR.

In conclusion, no design changes were completed during the specified time period that constituted a major change to either the liquid, solid or gaseous radwaste treatment systems.

River Bend Station 2014 Regulatory Guide 1.21 Report Page 17 of 91 XIV. PROCESS CONTROL PROGRAM (PCP)

There were two editorial changes to the PCP in 2014. A copy of that revision is attached to this report.

XV. INDUSTRY GROUND WATER PROTECTION INITIATIVE (GPI) - FINAL GUIDANCE DOCUMENT (NEI 07-07) OBJECTIVE ANNUAL REPORTING Ground water samples were taken in support of the GPI. These samples are not part of the Radiological Environmental Monitoring Program. The sample results for 2014 are located in Table 8.

River Bend Station made two NEI 07-07 voluntary notifications in 2014, which are being included here per NEI 07-07 Objective 2.4.c. The first notification occurred on January 8, 2014, when the bonnet on a temporary blow down line gate valve (RWS-0339-V8) cracked due to a few days of sub-freezing temperatures. This caused a circulating water/liquid radwaste discharge water mixture to leak onto the ground. A radioactive waste discharge was not in progress; however, due to the temporary piping configuration, a dead leg of radioactive water is sometimes present in the piping connected to the valve that ruptured. The exact volume released is unknown because the exact time the valve body failed is unknown. The volume released estimated to be between 100 and 1200 gallons and is based on times that workers were in the area and the observed leakage rate.

Actions were taken at the time of the leak to contain the water, and dams were successfully installed to prevent any water from reaching any storm drains. The spill was confined to the Owner Controlled Area. The water analysis indicated no gamma activity, and the maximum tritium sample value was 4.58E-06 uCi/ml.

Securing the Circulating Water System blow down stopped the leak and repairs weremade.

The second notification occurred on May 12, 2014 because of contaminated water leaking into the C-Tunnel. An Operator discovered a small amount of water (- 2 drips/minute) leaking into the C-Tunnel on the 67-foot elevation through a service water primary (SWP) piping penetration. The SWP is normally a radiologically clean system, and the water was sampled to determine if the service water pipe was leaking. The results indicated that the leak did not originate from the SWP system as was suspected so an additional sample was taken for radiological purposes.

Tritium was detected in the followup sample. The highest confirmed sample for tritium was 2.82E-05 uCi/ml. Tritium was the only radioisotope detected. Follow-up sampling and leak rate determinations indicated the tritium activity and leak rates varied and seemed to be affected by rainfall. Based on this information, it is believed that the water was coming from outside the C-Tunnel.

River Rend Station 2014 Regulatory Guide 1.21 Report Page 18 of 91 The only source of radioactive material capable of giving the activity level detected is two small-bore pipes in the overhead of C-Tunnel that have been used for liquid radwaste discharges. These pipes are approximately 16 feet above the SWP piping and have been out of service since 2012. The service water pipes and the liquid radwaste pipes are all below grade once they leave the C-Tunnel. It is possible the liquid radwaste pipes developed a leak below grade outside the building, and some remaining water leaked into the soil and moved down to the SWP pipe.

The water being detected is not in the nearest aquifer beneath the site, and the activity detected is not from a groundwater monitoring well. The bottom of the SWP line is about 11 feet above the water table.

Although likely insignificant, the potential offsite impacts for both events have been reviewed. The Upland Terrace Aquifer is the closest aquifer beneath the site. The Upland Terrace Aquifer is hydrologically connected to the Mississippi River Alluvial aquifer, and then to the Mississippi River, approximately two miles west of the facility. The site conceptual hydrology model indicates a down-gradient flow generally to the southwest from the CWS-MOV104 pit and C-Tunnel to the Mississippi River. River Bend Station site does not utilize ground water for drinking water use, and the nearest known drinking water user from the Mississippi River is many miles downstream below Baton Rouge, Louisiana. The most recent information River Bend Station has is all neighbors surrounding the station use the parish water supply for their primary source of drinking water. Intakes to the parish water supply are not downgradient of River Bend Station. Our geologist estimates that the activity detected in both events are not likely to be detected if they were to infiltrate to the Upland Terrace Aquifer and migrate to the Mississippi River due to decay, dilution and dispersion. Due to the significant dilution volume of the Mississippi River, there would not be any meaningful dose impact offsite. The potential annual dose for both events to a member of the public is estimated to be less than the 10 CFR 50 Appendix I dose limits.

Note: Volume considered being the total disposal volume of the container.

Radwaste Estimated Error %:

Waste types considered are processed solid waste (i.e. resin, filter media) and non-compactible/compactible dry active waste.

1. Possible Errors

a. Volume

b. Representative Sampling

c. Instrument/Counting

d. Dose to Curie Calculations

2. Volume Error Level indication for processed resins can be determined to +/- 0.5 inches. This correlates to approximately 1.0%. Container manufacturer stated design tolerance allows for 1.0% deviation from container dimensions. Volume error is not applicable to dry active waste.

3. Representative Sampling Error

River Bend Station 2014 Regulatory Guide 1.21 Report Page 34 of 91 Sampling error for processed resins is based upon obtaining a representative sample from the waste being processed using an iso-lock sampler. Sampling error from dry active waste is based upon obtaining a representative sample from the material being packaged. This error is estimated to be +/-

10% for all waste types, which is consistent with industry standards.

River Bend Station 2014 Regulatory Guide 1.21 Report Page 35 of 91 Effluent and Waste Disposal Annual Report 2014 Year Solid Waste and Irradiated Fuel Shipments Reporting Period from 01/01/14 to 12/31/14 Table 3 (continued)

4. Instrument/Counting Error The error caused by sample geometry, counting time, sample activity and instrument background is estimated to be +/- 10%. The error for radiological survey instrumentation is estimated to be +/- 20%.

This error is applicable to all waste types.

5. Dose to Curie Calculations Error The Dose to Curie method used to calculate activity suffers from analytical accuracy in that certain important parameters are neglected. These parameters are geometry of package, measuring instrument characteristics, build-up, internal attenuation effect, and external media attenuation. An activity correction factor is applied to provide adjustment for these factors. This error is applicable to all waste types.

(2) Liquid dose pathway is not considered due to the nature of activities that individuals are engaged in.

(3) National Guard/State Police are being evaluated, if applicable, for dose while stationed on site as members of the public. The adult age group is the only age group considered in this category. No National Guard in 2014.

(4) Workers have been permitted to stay long term at the Activity Center Trailer City beginning April 10, 2007. Effective August 15, 2014, site management closed the Activity Center Trailer City and all trailers were removed. Going forward, trailers will be allowed 30 days prior to and must be removed 14 days following refueling outages.

1.0 PURPOSE The Process Control Program (PCP) requires formulas, sampling, analyses, test and determinations to be made to ensure that the processing and packing of solid radioactive wastes based on demonstrated processing of actual or simulated wet solid wastes will be accomplished in such a way as to assure compliance with 10 CFR Parts 20, 61 and 71, State Regulations, burial ground requirements, and other requirements governing the disposal of solid radioactive waste. The scope of a PCP is to assure that radioactive waste will be handled, shipped, and disposed of in a safe manner in accordance with approved site or vendor procedures, whichever is applicable. [GGNS UFSAR, Chapter 16B.1 / TRM - 7.6.3.8 paragraph 1]

1.1 The purpose of this document is to provide a description of the solid radioactive waste Process Control Program (PCP) at all the Entergy fleet sites. The PCP describes the methods used for processing, classification and packaging low-level wet radioactive waste into a form acceptable for interim on-site storage, shipping and disposal, in accordance with 10 CFR Part 61 and current disposal site criteria.

1.2 To ensure the safe operation of the solid radwaste system, the solid radwaste system will be used in accordance with this Process Control Program to process radioactive wastes to meet interim on-site storage, shipping and burial ground requirements.

1.3 This document addresses the process control program in the context of disposal criteria, on-site processing and vendor processing requirements.

1.4 The Process Control Program implements the requirements of 10CFR50.36a and General Design Criteria 60 of Appendix A to 10CFR Part 50. The process parameters included in the Process Control Program may include but are not limited to waste type, waste pH, waste/liquid/solidification agent/catalyst ratios, waste oil content, waste principal chemical constituents, and mixing and curing times.

1.5 This document does NOT address the requirements for 10CFR Part 61.56 (waste characteristics) for material sent to intermediate processors, because the final treatment and packaging is performed at the vendor facilities.

3.0 DEFINITIONS

[1] Batch - A quantity of waste to be processed having essentially consistent physical and chemical characteristics as determined through past experience or system operation knowledge by the Radwaste Shipping Specialist. A batch could be a waste tank, several waste tanks grouped together or a designated time period such as between outages as with the DAW waste stream. An isolated quantity of feed waste to be processed having essentially constant physical and chemical characteristics.

(The addition or removal of water will not be considered to create a new batch).

[2] Certificate of Compliance - Document issued by the USNRC regulating use of a NRC licensed cask or issued by (SCDHEC) South Carolina Department of Health and Environmental Conservation regulating a High Integrity Container.

[3] Chelating Agents - EDTA, DTPA, hydroxy-carboxylic acids, citric acid, carbolic acid and glucinic acid.

[4] Compaction - The process of volume reducing solid waste by applying external pressure.

[5] Confirmatory Analysis - The practice of verifying that gross radioactivity measurements using MCA are reasonably consistent with independent laboratory sample data.

[6] Dewatered Waste - Wet waste that has been processed by means other than solidification, encapsulation, or absorption to meet the free standing liquid requirements of 10CFR Part 61.56 (a)(3) and (b)(2).

4.0, continued

[4] Each site RP Department - Radwaste Supervisor / Specialist (title may vary at the site's respectively) has the overall responsibility for implementing the PCP and is responsible for processing and transportation is tasked with the day-to-day responsibilities for the following:

" Implementing the requirements of this document.

• Ensuring that radioactive waste is characterized and classified in accordance with 10CFR Part 61.55 and Part 61.56.

" Ensuring that radioactive waste is characterized and classified in accordance with volume reduction facility and disposal site licenses and other requirements.

" Designating other approved procedures (if required) to be implemented in the packaging of any specific batch of waste.

• Providing a designated regulatory point of contact between the Plant and the NRC, volume reduction facility or disposal site.

• Maintaining records of on-site and off-site waste stream sample analysis and Plant evaluations.

• Suspending shipments of defectively processed or defectively packaged radioactive wastes from the site when the provisions of this process control program are not satisfied.

5.0 DETAILS An isotopic analysis SHALL be performed on every batch for each waste stream so that the waste can be classified in accordance with 10CFR61. The isotopic and curie content of each shipping container SHALL be determined in accordance with 49CFR packaging requirements. The total activity in the container may be determined by either isotopic analysis or by dose-rate-to-curie conversion.

5.1. Precautions and Limitations

[1] Precautions (a) Radioactive materials SHALL be handled in accordance with applicable radiation protection procedures.

(b) All radioactive waste processed on-site OR off-site by vendors must be processed or packaged to meet the minimum requirements listed in 10CFR Part 61.56 (a) (1) through (8).

5. 1[1], continued (c) If the provisions of the Process Control Program are not satisfied, suspend shipment of the defectively processed or defectively packaged waste from the site. Shipment may be accomplished when the waste is processed / packaged in accordance with the Process Control Program.

(d) The generation of combustible gases is dependent on the waste form, radioactive concentration and accumulated dose in the waste. Changes to organic inputs (e.g. oil) to waste stream may change biogas generation rates.

[2] Limitations (a) Only qualified personnel will characterize OR package radioactive waste OR radioactive materials for transportation or disposal.

(b) All site personnel that have any involvement with radioactive waste management computer software SHALL be familiar with its functions, operation and maintenance.

5.2. Waste Management Practices

[1] Waste processing methods include the following:

(a) Present and planned practice is NOT to solidify or encapsulate any waste streams.

(b) Waste being shipped directly for burial in a HIC (High Integrity Container) is dewatered to less than 1 percent by volume prior to shipment.

(c) Waste being shipped directly for burial in a container other than a HIC is dewatered to less than 0.5 percent by volume prior to shipment.

(d) IF solidification is required in the future, THEN at least one representative test specimen from at least every 10th batch of each type of radioactive waste will be checked to verify solidification.

(1) IFany specimen fails to verify solidification, THEN the solidification of the batch under test SHALL be suspended until such time as additional test specimens can be obtained, alternative solidification parameters can be determined, and a subsequent test verifies solidification. Ifalternative parameters are determined, the subsequent tests shall be verified using the alternative parameters determined.

5.2[1](d), continued (2) IF the initial test specimen from a batch of waste fails to verify solidification, THEN provide for the collection and testing of representative test specimens from each consecutive batch of the same type of waste until at least 3 consecutive initial test specimens demonstrates solidification. The process SHALL be modified as required to assure solidification of subsequent batches of waste.

[2] Operation and maintenance of dewatering systems and equipment include the following:

(a) Present and planned practice is to utilize plant personnel supplemented by vendor personnel or contracted vendor personnel, to operate AND maintain dewatering systems and equipment (as needed to meet disposal site requirements).

(b) All disposal liners are manufactured by and purchased from QA-approved vendors.

[3] ALARA considerations are addressed in all phases of the processes involving handling, packaging AND transfer of any type OR form of radioactive waste (dewatered or dry).

Resin, charcoal media, spent filter cartridges AND sludges are typically processed within shields. Sluiceable demineralizers are shielded when in service. Radiation exposure and other health physics requirements are controlled by the issuance of a Radiation Work Permit (RWP) for each task.

5.3. Waste Stream Sampling Methods and Freauencv

[1] The following general requirements apply to Plant waste stream sampling:

(a) Treat each waste stream separately for classification purposes.

(b) Ensure samples are representative of or can be correlated to the final waste form.

(c) Determine the density for each new waste stream initially or as needed (not applicable for DAW and filters).

(d) Perform an in-house analysis for gamma-emitting radionuclides for each sample sent to an independent laboratory.

(e) Periodically perform in-house analysis for gamma emitting radionuclides for comparison to the current data base values for gamma emitters. (The current database is usually based on the most recent independent laboratory results.)

(f) Resolve any discrepancies between in-house results AND the independent laboratory results for the same or replicate sample as soon as possible.

(g) Maintain records of on-site and off-site waste stream sample analysis and evaluations.

5.3, continued

[2] When required, waste stream samples should be analyzed, re-evaluated and if necessary, shipped to a vendor laboratory for additional analysis. The same is true when there is a reason to believe that an equipment or process change has significantly altered the previously determined scaling factors by a factor of 10.

Specific examples include but are not limited to:

" Changes in oxidation reduction methods such as zinc, injection, hydrogen water chemistry, 0 Changes in purification methods including media specialization, media distribution, ion/cation ratios,

• Changes in fuel performance criteria including fuel leaks

• Other changes in reactor coolant chemistry.

• Sustained, unexplained, changes in the routinely monitored Beta/Alpha ratios, as determined by Radiation Protection,

• When there is an extended reactor shutdown (> 90 days).

• When there are changes to liquid waste processing, such as bypassing filters, utilizing filters or a change in ion exchange media.

• When there are changes to the waste stream that could change the biogas generation rate.

[3] The following requirements apply to infrequent or abnormal waste types:

(a) Infrequent OR abnormal waste types that may be generated must be evaluated on a case-by-case basis.

(b) The RP Department Supervisor / Specialist responsible for processing AND shipping will determine if the waste can be correlated to an existing waste stream.

(c) IF the radioactive waste cannot be correlated to an existing waste stream, THEN the RP Department Supervisor / Specialist responsible for processing and shipping SHALL determine specific off-site sampling and analysis requirements necessary to properly classify the material.

[4] Specific sampling methods and data evaluation criteria are detailed in EN-RW-104 for specific waste streams.

5.4. Waste Classification

[1] General requirements for scaling factors include the following:

(a) The Plant has established an inferential measurement program whereby concentrations of radionuclides which cannot be readily measured are estimated through ratio-ing with radionuclides which can be readily measured.

(b) Scaling factor relationships are developed on a waste stream-specific basis.

These relationships are periodically revised to reflect current independent lab data from direct measurement of samples. The scaling factor relationships currently used by the sites are as follows:

" Hard to detect ACTIVATION product radionuclides and C-1 4 are estimated by using scaling factors with measured Co-60 activities.

• Hard to detect FISSION product radionuclides and H-3, Tc-99 and 1-129 are estimated by using scaling factors with measured Cs-137 activities.

" Hard to detect TRANSURANIC radionuclides are estimated by using scaling factors with measured Ce-144 activities. Where Ce-144 cannot be readily measured, transuranics are estimated by using scaling factors with measured Cs-1 37 activities. Second order scaling of transuranics is acceptable when Cs-137 and Ce-1 44 are not readily measurable.

[2] General requirements for the determination of total activity and radionuclide concentrations include the following:

(a) The activity for the waste streams is estimated by using either Gross Radioactivity Measurement OR Direct Measurement of Radionuclides. Current specific practices are as follows:

" DAW - Gross radioactivity measurement in conjunction with the RADMAN computer codes, other approved computer codes or hand calculation.

" Filters - Gross radioactivity measurement in conjunction with the FILTRK computer code, other approved computer codes or hand calculation.

" All Other Waste Streams - Direct measurement of radionuclides in conjunction with the RADMAN computer codes, other approved computer codes or hand calculation.

(b) Determination of the NRC waste classification is performed by comparing the measured or calculated concentrations of significant radionuclides in the final waste form to those listed in 10CFR Part 61.55.

5.5. Quality Control

[1] The RADMAN computer code provides a mechanism to assist the Plant in conducting a quality control program in accordance with the waste classification requirements listed in 10CFR Part 61.55. All waste stream sample data changes are written to a computer data file for future review and reference.

[2] Audits and Management Review includes the following:

(a) Appendix G to 1 OCFR20 requires conduct of a QC program which must include management review of audits.

(b) Management audits of the Plant Sampling and Classification Program SHALL be periodically performed to verify the adequacy of maintenance sampling and analysis.

(c) Audits and assessments are performed and documented by any of the following:

• Radiation Protection Department
