Docket No 50-390 WATTS BAR NUCLEAR PLANT (WBN) - UNIT I - 2002 ANNUAL RADIOACTIVE EFFLUENT RELEASE REPORT (ARERR)

Provided in Enclosure 1 is the 2002 ARERR for WBN. This report fulfills the requirements of Technical Specification 5.9.3 and addresses the period from January 1, 2002, through December 31, 2002. Attachment 1 of the ARERR documents the deviations from Offsite Dose Calculation Manual (ODCM) requirements Attachment 2 documents that there were no radiation monitors inoperable for greater than 30 days Technical Specification (TS) 5.7 2.3 requires that an updated version of the ODCM be submitted with the AREER if changes occurred during the AREER reporting period. Revision 8 of the ODCM was in effect during the 2002 AREER reporting period. This revision initially became effective on September 27, 2001, and was provided in the 2001 ARERR (TVA's letter dated April 30, 2002). Therefore, a complete copy of the ODCM is not provided in this report. addresses the requirements of the Process Control Program (PCP) which are reported in conjunction with the ARERR in accordance with the ODCM. During the preparation of the 2002 ARERR, an error was noted in a computer program used to generate the report. The reports for previous years were reviewed to establish if the data provided in the reports was impacted by the program error Based on this review, the data for the 1999 and 2001 ARERRs required correction The corrected information for the two reports is provided in Enclosures 3 and 4.

2.

Air dose due to noble gases released in gaseous effluents to areas at and beyond the unrestricted area boundary shall be limited to the following:

a. Less than or equal to 5 mrad for gamma radiation and less than or equal to 10 mrad for beta radiation during any calendar quarter.

b. Less than or equal to 10 mrad for gamma radiation and less than or equal to 20 mrad for beta radiation during any calendar year.

3.

Dose to a member of the public from iodine-1 31, iodine-1 33, tritium, and all radionuclides in particulate form with half-lives greater than eight days in gaseous effluents released to areas at and beyond the unrestricted area boundary shall be limited to the following:

a. Less than or equal to 7.5 mrem to any organ during any calendar quarter.

b. Less than or equal to 15 mrem to any organ during any calendar year.

B. Liquid Effluents

1. The concentration of radioactivity released in liquid effluents to unrestricted areas shall be limited to 10 times the concentrations specified in Title 10 of the Code of Federal Regulations, Part 20 (Standards for Protection Against Radiation), Appendix B, Table 2, Column 2, for radionuclides other than dissolved or entrained noble gases. For dissolved or entrained noble gases, the concentration shall be limited to 2.0 E-04 IiCi/ml total activity.

2. The dose or dose commitment to a member of the public from radioactivity in liquid effluents released to unrestricted areas shall be limited to:

a. Less than or equal to 1.5 mrem to the total body and less than or equal to 5 mrem to any organ during any calendar quarter.

b. Less than or equal to 3 mrem to the total body and less than or equal to 10 mrem to any organ during any calendar year.

2002 WATTS BAR NUCLEAR PLANT EFFLUENT AND WASTE DISPOSAL ANNUAL REPORT SUPPLEMENTAL INFORMATION

2. Effluent Concentration Limits A.

Liquids The Effluent Concentration Limits (ECL) for liquids are those listed in 10 CFR 20, Appendix B, Table 2, Column 2. For dissolved and entrained gases the ECL of 2.OE-04 [tCi/ml is applied. This ECL is based on the Xe-1 35 concentration in air (submersion dose) converted to an equivalent concentration in water as discussed in the International Commission on Radiological Protection (ICRP), Publication 2.

B. Gaseous Concentration limits for gaseous releases are met through compliance with the maximum permissible dose rates for gaseous releases as defined in plant Offsite Dose Calculation Manual (ODCM) and presented in Section 1.A.1 of this report.

3.

Average Energy Watts Bar's ODCM limits the dose equivalent rates due to the release of noble gases to less than or equal to 500 mrem/year to the total body and less than or equal to 3000 mrem/year to the skin.

Therefore, the average beta and gamma energies (E) for gaseous effluents as described in Regulatory Guide 1.21, "Measuring, Evaluation, and Reporting Radioactivity in Solid Wastes and Releases of Radioactive Materials in Liquid and Gaseous Effluents from Light-Water-Cooled Nuclear Power Plants," are not applicable.

4.

Measurements And Approximations Of Total Radioactivity Radioactivity measurements performed in support of the WBN Offsite Dose Calculation Manual (ODCM) meet the Lower Limit of Detection requirements given in ODCM Tables 2.2-1 and 2.2-2.

A.

Liquid Effluents Batch (Radwaste and Condensate Demineralizer tanks)

Total gamma isotopic activity concentrations are determined on each Radwaste batch tank prior to release. The total activity of a released batch is determined by summing each nuclide's concentration and multiplying by the total volume discharged. Composite samples are maintained and analyzed monthly for tritium and gross alpha, and quarterly for Iron-55, Strontium-89, and Strontium-90. During periods of no significant identified primary to secondary leakage, the volume from each Condensate Demineralizer tank release is obtained and the feedwater tritium concentration is used to determine the curies of tritium released.

Continuous Releases (Turbine Building Sump and Steam Generator Blowdown)

During periods of no significant identified primary to secondary leakage, the volume released from the TBS and SGB is obtained. The TBS tritium concentration is determined via weekly grab samples. The feedwater tritium concentration is used to determine the curies of tritium released from SGB.

2002 WATTS BAR NUCLEAR PLANT EFFLUENT AND WASTE DISPOSAL ANNUAL REPORT SUPPLEMENTAL INFORMATION B.

Fission and Activation Gases Airborne effluent gaseous activity is continuously monitored and recorded. Weekly grab samples from the auxiliary building and monthly grab samples from the service building are taken and analyzed to determine the quantity of noble gas activity released based on the total flows for the sample period. Also, noble gas samples are collected and evaluated following startup, shutdown, or rated thermal power change exceeding 15 percent within one hour (sampling only required if dose equivalent 1-131 concentration in the primary coolant or the noble gas activity monitor shows that the containment activity has increased more than a factor of 3).

The quantity of noble gases released through the shield building exhaust due to purging of containment is determined by sampling prior to the beginning of the purge, and periodically monitoring the associated countrate during the purge. The total activity released is determined from the total flow recorded for each purge. Also, noble gas samples are collected and evaluated for ongoing containment purges following startup, shutdown, or rated thermal power change exceeding 15 percent within one hour (sampling only required if dose equivalent 1-131 concentration in the primary coolant or the noble gas activity monitor shows that the containment activity has increased more than a factor of 3).

The quantity of noble gases released through the shield building exhaust due to the batch release of waste gas decay tanks is determined by sampling each tank prior to release. The total activity released is determined from the total pressure change recorded for the tank during the release.

C.

lodines and Particulates in Gaseous Releases Iodine and particulate activity is continuously sampled. Charcoal and particulate samples are taken from the shield and auxiliary building exhausts and analyzed at least weekly to determine the total activity released from the plant based on the total vent flows recorded for the sampling period. Also, particulate and charcoal samples are taken from the auxiliary and shield building exhausts once per 24 hours2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months for 7 days following startup, shutdown, or a rated thermal power change exceeding 15 percent within one hour (if dose equivalent 1-131 concentration in the primary coolant or the noble gas activity monitor shows that the containment activity has increased more than a factor of 3).

2002 WATTS BAR NUCLEAR PLANT EFFLUENT AND WASTE DISPOSAL ANNUAL REPORT Radiological Impact Introduction Potential doses to maximum individuals and the population around Watts Bar are calculated for each quarter as required in Section 5.2 of the Offsite Dose Calculation Manual (ODCM).

Measured plant releases for the reporting period are used to estimate these doses. Dispersion of radioactive effluents in the environment is estimated using meteorological data and riverflow data measured during the period. In this report, the doses resulting from releases are described and compared to limits established for Watts Bar.

Dose Limits The ODCM specifies limits for the release of radioactive effluents, as well as limits for doses to the general public from the release of radioactive effluents. These limits are set well below the Technical Specification limits which govern the concentrations of radioactivity and doses permissible in unrestricted areas. This ensures that radioactive effluent releases are As Low As Reasonably Achievable.

Dose Calculations Estimated doses to the public are determined using computer models (the Gaseous Effluent Licensing Code, GELC, and the Quarterly Water Dose Assessment Code, QWATA). These models are based on guidance provided by the NRC (in Regulatory Guides 1.109, 1.111 and 1.113) for determining the potential dose to individuals and populations living in the vicinity of the plant. The area around the plant is analyzed to determine the pathways through which the public may receive a dose. The doses calculated are a representation of the dose to a "maximum exposed individual." Some of the factors used in these calculations (such as ingestion rates) are maximum values.

Many of these factors are obtained from NUREG/CR-1004. The values chosen will tend to overestimate the dose to this "maximum" person.

The expected dose to actual individuals is lower. The calculated doses are presented in Tables 6A, 6B, 7A and 7B.

Doses From Airborne Effluents For airborne effluents, the public can be exposed to radiation from several sources: direct radiation from the radioactivity in the air, direct radiation from radioactivity deposited on the ground, inhalation of airborne radioactivity, ingestion of vegetation which contains radioactivity deposited from the atmosphere, and ingestion of milk and beef which contains radioactivity deposited from the atmosphere onto vegetation and subsequently eaten by milk and beef animals.

Airbome Discharge Points All releases from Watts Bar are considered ground-level releases.

The ground-level Joint Frequency Distribution (JFD) is derived from wind speeds and directions measured 10 meters above ground and from the vertical temperature difference between 10 and 46 meters, and are presented for each quarter on pages El-25 through El-52.

E1-16

2002 WATTS BAR NUCLEAR PLANT EFFLUENT AND WASTE DISPOSAL ANNUAL REPORT Radiological Impact Meteorological Data Meteorological variables at Watts Bar are measured continuously. Measurements collected include wind speed, wind direction, and temperature at heights of 10, 46, and 91 meters above the ground. Quarterly joint frequency distributions (JFDs) are calculated for each release point using the appropriate levels of meteorological data. A joint frequency distribution gives the percentage of the time in a quarter that the wind is blowing out of a particular upwind compass sector in a particular range of wind speeds for a given stability class A through G. The wind speeds are divided into nine wind speed ranges.

Calms are distributed by direction in proportion to the distribution of non-calm wind directions less than 0.7 m/s (1.5 mph). Stability classes are determined from the vertical temperature difference between two measurement levels.

Extemal Exposure Dose Dose estimates for maximum external air dose (gamma-air and beta-air doses) are made for points at and beyond the unrestricted area boundary as described in the Watts Bar ODCM. The highest of these doses is then selected.

Submersion Dose External doses to the skin and total body, due to submersion in a cloud of noble gases, are estimated for the nearest residence in each sector. The residence with the highest dose is then selected from all sectors.

Organ Dose Doses to organs due to releases of airborne effluents are estimated for the inhalation, ground contamination, and ingestion pathways.

The ingestion pathway is further divided into four possible contributing pathways: ingestion of cow/goat milk, ingestion of beef, and ingestion of vegetables. Doses from applicable pathways are calculated for each real receptor location identified in the most recent land use survey. To determine the maximum organ dose, the doses from the pathways are summed for each receptor.

For the ingestion dose, however, only those pathways that exist for each receptor are considered in the sum, i.e., milk ingestion doses are included only for locations where milk is consumed without commercial preparation and vegetable ingestion is included only for those locations where a garden is identified. To conservatively account for beef ingestion, a beef ingestion dose equal to that for the highest unrestricted area boundary location is added to each identified receptor.

For ground contamination, the dose added to the organ dose being calculated is the total body dose calculated for that location, i.e., it is assumed that the dose to an individual organ is equal to the total body dose.

Doses from airborne effluents are presented in Tables 6A and 6B.

Doses From Liquid Effluents For liquid effluents, the public can be exposed to radiation from three sources: the ingestion of water from the Tennessee River, the ingestion of fish caught in the Tennessee River, and direct exposure from radioactive material deposited on the river shoreline sediment (recreation).

El-17

2002 WATTS BAR NUCLEAR PLANT EFFLUENT AND WASTE DISPOSAL ANNUAL REPORT Radiological Impact The concentrations of radioactivity in the Tennessee River are estimated by a computer model which uses measured hydraulic data downstream of Watts Bar. Parameters used to determine the doses are based on guidance given by the NRC (in Regulatory Guide 1.109) for maximum ingestion rates, exposure times, etc. Wherever possible, parameters used in the dose calculation are site specific use factors determined by TVA. The models that are used to estimate doses, as well as the parameters input to the models, are described in detail in the Watts Bar ODCM.

Liquid Release Points and River Data Radioactivity concentrations in the Tennessee River are calculated assuming that releases in liquid effluents are continuous. All routine liquid releases from Watts Bar, located at Tennessee River Mile 528.5, are made through diffusers which extend into the Tennessee River. It is assumed that releases to the river through these diffusers will initially be entrained in one-tenth of the water which flows past the plant. The QWATA code makes the assumption that this mixing condition holds true until the water is completely mixed at Tennessee River Mile 510.0.

Doses are calculated for locations within a 50 mile radius downstream of the plant site. The maximum potential recreation dose is calculated for a location immediately downstream from the plant outfall. The maximum individual dose from ingestion of fish is assumed to be that calculated for the consumption of fish caught anywhere between the plant and the first downstream dam (Chickamauga Dam).

The maximum individual dose from drinking water is assumed to be that calculated at the nearest downstream public water supply (Dayton, TN). This could be interpreted as indicating that the maximum individual, as assumed for liquid releases from Watts Bar, is an individual who obtains all of his drinking water at Dayton, TN, consumes fish caught from the Tennessee River between Watts Bar and Chickamauga Dam, and spends 500 hours0.00579 days 0.139 hours 8.267196e-4 weeks 1.9025e-4 months per year on the shoreline just below the outfall from Watts Bar. Dose estimates for the maximum individual due to liquid effluents for each quarter in the period are presented in Tables 7A and 7B, along with the average river flows past the plant site for the periods.

Population Doses Population doses for highest exposed organ due to airborne effluents are calculated for an estimated 1,066,600 persons living within a 50-mile radius of the plant site.

Doses from external pathways and inhalation are based on the 50-mile human population distribution.

Ingestion population doses are calculated assuming that each individual consumes milk, vegetables, and meat produced within the sector annulus in which he resides. Doses from external pathways and inhalation are based on the 50-mile human population distribution.

Population doses for total body and the maximum exposed organ due to liquid effluents are calculated for the entire downstream Tennessee River Population. Water ingestion population doses are calculated using actual population figures for downstream public water supplies. Fish ingestion population doses are calculated assuming that all sport fish caught in the Tennessee River are consumed by the Tennessee River population. Recreation population doses are calculated using actual recreational data on the number of shoreline visits at downstream locations.

Population dose estimates for airborne and liquid effluents are presented in Tables 6A, 6B, 7A and 7B.

2002 WATTS BAR NUCLEAR PLANT EFFLUENT AND WASTE DISPOSAL ANNUAL REPORT Radiological Impact Direct Radiation External gamma radiation levels were measured by thermoluminescent dosimeters (TLDs) deployed around WBN as part of the offsite Environmental Radiological Monitoring Program. The quarterly gamma radiation levels determined from these TLDs during this reporting period averaged 16.0 mR/quarter at onsite (at or near the site boundary) stations and 14.5 mR/quarter at offsite stations or 1.5 mR/quarter higher onsite than at offsite stations. This difference is consistent with levels measured for preoperation and construction phases of the WBN plant site where the average radiation levels onsite were generally 2-6 mR/quarter higher than the levels offsite. This may be attributable to natural variations in environmental radiation levels, earth moving activities onsite, the mass of concrete employed in the construction of the plants, or other undetermined influences.

Fluctuations in natural background dose rates and in TLD readings tend to mask any small increments which may be due to plant operations. Thus, there was no identifiable increase in dose rate levels attributable to direct radiation from plant equipment and/or gaseous effluents.

Dose To A Member Of The Public Inside The Unrestricted Area Boundary As stated in the Watts Bar Offsite Dose Calculation Manual, an evaluation of the dose to a member of the public inside the unrestricted area boundary is performed for a hypothetical TVA employee who works just outside the restricted area boundary for an entire work year (2000 hours0.0231 days 0.556 hours 0.00331 weeks 7.61e-4 months ).

Results from onsite TLD measurements indicated that the highest onsite TLD reading outside the Radiological Control Area was 108 mrem. Using this value, subtracting an annual background value of approximately 64 mrem/year (see previous section), and multiplying by the ratio of the occupancy times (2000/8760), the highest external dose to a member of the public inside the unrestricted area boundary would be 10.0 mrem. The doses due to radioactive effluents released to the atmosphere calculated in this report would not add a significant amount to this measured dose. This dose is well below the 10 CFR 20 annual limit of 100 mrem.

Total Dose To determine compliance with 40 CFR 190, annual total dose contributions to the maximum individual from Watts Bar radioactive effluents and all other nearby uranium fuel cycle sources are considered.

The annual dose to any organ other than thyroid for the maximum individual is conservatively estimated by summing the following doses: the total body air submersion dose for each quarter, the critical organ dose (for any organ other than the thyroid) from airborne effluents for each quarter from ground contamination, inhalation and ingestion, the total body dose from liquid effluents for each quarter, the maximum organ dose (for any organ other than the thyroid) from liquid effluents for each quarter, and any identifiable increase in direct radiation dose levels as measured by the environmental monitoring program. This dose is compared to the 40 CFR 190 limit for total body or any organ dose (other than thyroid) to determine compliance.

The annual thyroid dose to the maximum individual is conservatively estimated by summing the following doses: the total body air submersion dose for each quarter, the thyroid dose from airborne effluents for each quarter, the total body dose from liquid effluents for each quarter, the thyroid dose from liquid effluents for each quarter, and any identifiable increase in direct radiation dose levels as measured by the environmental monitoring program. This dose is compared to the 40 CFR 190 limit for thyroid dose to determine compliance. Cumulative annual total doses are presented in Table 8.

1.0 INTRODUCTION

1.1 PURPOSE The purpose of the Watts Bar Nuclear Plant (WBN) Process Control Program (PCP) is to establish a program which provides reasonable assurance that all radioactive wastes processed at WBN for disposal at a land disposal facility are processed and packaged such that applicable Federal and State regulations and disposal site criteria are satisfied. The PCP contains a general description of the methods for controlling the processing and packaging of radioactive wastes, specific parameters for each method, and the administrative controls and quality assurance required to ensure compliance with applicable regulations and requirements. This PCP is not applicable to wastes transported to an off-site vendor for processing.

1.2 SCOPE This PCP applies to the processing of wet solid radioactive wastes generated as a result of plant operation and maintenance. This PCP does not apply to the treatment of mixed radioactive and hazardous wastes.

2.0 DETAILS 2.1 WASTE CHARACTERISTICS A.

Waste Streams I.

There are six waste streams that have been identified at WBN. These are primary resins, secondary resins, mobile demineralizer resin, filter elements, oil, and dry active waste (DAW). This PCP is not normally applicable to DAW. Other waste streams may be identified based upon plant operating characteristics.

2.

Primary resins are collected in the spent resin storage tank for blending, decay, and storage. Primary resin sources are Chemical and Volume Control System (CVCS) letdown dernineralizers, boron recovery demineralizers, and the fuel pool demineralizers.

3.

Secondary resins are generated from the condensate polisher demineralizers.

4.

Mobile demineralizer resins are fed by several sources including floor drain wastes, equipment drain wastes, laundry and hot shower wastes, and chemical wastes.

5.

Filter elements will be accumulated from one or more plant systems. These are CVCS, seal injection, boron recovery, and spent fuel pool clean-up.

6.

Oil is contaminated with radioactivity from various areas within the plant, as a result of normal operation and maintenance.

7.

The Condensate Demineralizer Waste Evaporator (CDWE) is not part of the Unit I license, but may be incorporated into the Unit 2 license application. If the CDWE is to be operated as part of the Unit 2 startup, the PCP shall be revised to incorporate the processing of the CDWE bottoms.

8.

DAW is generated within the plant and is not appropriately attributed to the above mentioned waste streams. DAW normally includes paper, plastic, wood, metal, and other such material generated as a result of the operation and maintenance of the plant.

WBN PCP PROCESS CONTROL PROGRAM Revision 0 UNIT 0 Page 6 of 11 B.

Waste Form Wastes are processed as appropriate to ensure that the minimum physical characteristics required by 10 CFR 61 and disposal site criteria are met. All class B and C waste must be stabilized. This shall be accomplished by placement into a high integrity container (HIC), or by solidification using a process that produces a product which meets the stability requirements of 10 CFR 61, per section 2.2 of this PCP. The vendors topical report shall include documentation of testing which verifies that the HIC or solidified product meets these stability requirements. Additionally, WBN shall comply with Federal and/or State requirements imposed specifically on an approved HIC or solidification product which limit the type and/or radioactive concentration of the waste to be placed in the HIC or solidified product.

C.

Waste Classification Radioactive waste shall be classified as Class A, B, or C in accordance with the requirements of 10 CFR 61, using one or more of the classification methods given in the USNRC's "Low-Level Waste Licensing Branch Technical Position on Radioactive Waste Classification (May 1983)."

Waste classification shall be in accordance with approved station procedures.

The following specific requirements shall be incorporated in the program for sampling and analysis for waste classification:

1.

Annual analysis shall be performed on representative samples of each waste stream for the nuclides listed in Table 1 and Table 2 of 10 CFR 61.55. For waste streams that are not processed annually, the annual analysis need not be performed until the waste is processed. Isotopic data from other PWR's may be utilized until annual analysis can be performed.

2.

The results of these annual analysis shall be used to develop isotopic abundances and scaling factors for difficult to measure nuclides (i.e., beta emitters and transuranics) based on correlations between those nuclides and more easily measured gamma emitters.

3.

Calculational methods for determining the total activity in each container shall be developed which utilizes the results from the annual analysis.

4.

The classification program shall establish criteria and include provisions for an increased frequency for sampling and analysis required by paragraph 1 above, if the waste stream isotopic content may have changed by a factor of 10.

2.2 PROCESSING OF WET RADIOACTIVE WASTE A.

Processing Methods Wet radioactive waste processed at WBN shall be processed into a form acceptable for disposal at a licensed facility. Processing shall be performed utilizing vendor supplied equipment operated in accordance with the vendor's PCP and procedures Any vendor selected to provide services or products used for compliance with 10 CFR 61 stability requirements shall have a topical report addressing 10 CFR 61 requirements under review or approved by the NRC. The topical reports and PCP's of other vendors may be referenced in this PCP even if all vendors are not actively providing service or products at WBN. However, if any vendor is selected whose documents are not referenced, this document shall be revised to reference them.

WBN PCP PROCESS CONTROL PROGRAM Revision 0 UNIT 0 Page 7 of 11 B.

System Qualification Tests

1.

Prior to the initial solidification of a given waste stream using a specified process, a test shall be conducted to demonstrate the ability of the process to produce an acceptable waste form over the range of critical parameters identified during the prequalification testing. Bounds for critical parameters and specific operating limits shall be specified in the vendor's PCP.

2.

These tests shall be performed on laboratory scale or full scale specimens and shall ensure that the acceptance criteria specified in Section 2.2.E are achieved.

3.

The dewatering process shall specify an endpoint for each dewatering evolution so as to assure that the acceptance criteria specified in Section 2.2.E are achieved.

C.

Batch Processing Each batch of waste offered for processing shall be sampled and analyzed, as appropriate, in accordance with site procedures, the vendor's PCP and the topical report that addresses the 10 CFR 61 stability requirements. This sampling shall:

1.

Provide the necessary data to estimate curie content and to perform the waste classification analysis.

2.

When solidification is involved, sampling shall provide data necessary to:

a.

Ensure that waste stream parameters are within the bounds for critical parameters established in the vendor's PCP and topical report.

b.

Verify the application of preestablished mix ratios.

D.

Testing/Inspections

1.

Tests are performed on those wastes which are solidified to ensure the adequacy of the solidification agent and/or procedural technique. The vendor's PCP shall be used to verify the solidification of at least one representative test specimen from at least every tenth batch of each type waste being processed.

2.

If any test specimen fails to verify solidification, 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 in accordance with the vendor's PCP, and a subsequent test verifies solidification. Solidification of the batch may then be resumed using the alternative solidification parameters determined by the vendor's PCP.

3.

If the initial test specimen from a batch fails to verify solidification, the vendor's PCP shall provide for the collection and testing of representative test specimens from each consecutive batch of waste until at least 3 consecutive test specimens demonstrate solidification.

WBN PCP PROCESS CONTROL PROGRAM Revision 0 UNIT 0 Page 8 of 11 E.

Acceptance Criteria

1.

All classes of waste shall satisfy the following acceptance criteria:

a.

Liquid wastes shall be solidified.

b.

Solid waste containing liquids shall not contain freestanding liquid in excess of 1% of the internal volume of the container.

2.

For wastes which require structural stability, the acceptance criteria are as follows:

a.

The waste shall have structural stability.

b.

Not withstanding the provisions of Section 2.2.E. 1, liquid wastes or wastes containing liquid shall be converted into a form in which the freestanding liquid shall not exceed 1% of the internal volume of the container when contained in a HIC, or 0.5% of the volume of the waste for waste processed to a stable form.

F.

Corrective Actions With processing not meeting the above acceptance criteria or otherwise not meeting disposal site, shipping and/or transportation requirements, suspend shipment of inadequately processed waste and correct the PCP, procedures, and/or waste processing equipment as necessary to prevent recurrence. The disposition of inadequately processed wastes will be handled on a case-by-case basis.

2.3 WASTE STREAM PROCESSING METHODS A.

Spent Resins

1.

Normally spent resins are processed for disposal by dewatering. The resin is transferred to the liner or HIC where it is processed utilizing vendor supplied services, per Section 2.2.

2.

Alternatively, resins may be processed for disposal by solidification. The resins shall be sampled for isotopic content and PCP parameters as defined in the vendor's PCP. The resins are transferred to the vendor's processing skid where they are solidified per Section 2.2.

B.

Spent Filter Elements Spent filter elements are surveyed for dose rate upon removal from the system. The measured dose rate is used to calculate isotopic content using a dose-to-curie conversion and scaling factors per Section 2.1. Based on the isotopic content and waste classification, the appropriate process and container to be used for disposal are determined. Normally, filters are placed in a liner or HIC and dewatered; however, filters may be dried and handled as DAW if conditions allow, or may be encapsulated.

WBN PCP PROCESS CONTROL PROGRAM Revision 0 UNIT 0 Page 9 of 11 C.

Miscellaneous Wastes Sludges and other miscellaneous wastes will be collected and handled on a case-by-case basis, and processed per Section 2.2. Oil and, on a case-by-case basis, other acceptable liquid waste will normally be shipped off-site to a licensed incinerator for disposal.

2.4 ADMINISTRATIVE CONTROLS A.

Procedures Activities associated with the implementation of the requirements of this program shall be conducted in accordance with approved procedures or vendor documents that have been reviewed and approved by WBN.

B.

Quality Assurance/Quality Control Quality assurance assessments are conducted by the Quality Assurance organization, and by the Corporate Radiological Control organization. Assessment findings are reviewed by WBN management. Quality control measures include site review of all radwaste vendor procedures before use and verification, by site personnel, of end points or acceptance criteria in vendor procedures. Quality control of solidification methods is performed through controlled testing of a minimum of one sample from each batch to be solidified. Proportions of solidification agents are established which meet the standards for waste form and free standing liquid criteria.

C.

Training Personnel involved in processing radioactive waste for shipment are trained in site procedures, regulatory requirements, and disposal site criteria applicable to the individuals responsibilities.

The retraining of personnel shall be at the frequency specified in site procedures.

D.

Licensee Initiated Changes to the PCP

1.

Licensee initiated changes to the PCP shall be documented and records of reviews performed shall be retained for the duration of the unit Operating License. This documentation shall contain:

a.

Sufficiently detailed information to support the change(s) and appropnate analyses or evaluations justifying the change(s); and

b.

A determination that the change(s) maintain the overall conformance of the solidified waste product to existing requirements of Federal, State, or other applicable regulations.

c.

Shall be effective after review and acceptance by the Plant Operations Review Committee (PORC) and the approval of the Plant Manager.

2.
