SUPPLEMENTAL INFORMATION Revision 10 of the Process Control Procedure (RW-AA-100) was implemented at LaSalle Station on January 15, 2014. A copy of Revision 10 has been included as Appendix A to this report. A summary of the changes in Revision 10 are described below:

a.Step 4.2.9.2. was modified to include WCS (Waste Control Specialists LLC) located in Andrews, TX as a storage/disposal facility and as a HIC (High Integrity Container) supplier.

b.Step 4.2.13. was added to the document. The step states that "Concentration averaging may be PERFORMED to combine LLRW [Low Level Radioactive Wastes] having different concentrations to form a homogeneous mixture..." The mixture is required to be in conformance with the guidanceprovided in the NRC's Branch Technical Position on Concentration Averaging and Encapsulation.

January 1995.

c.Step 4.2.14. was added to the document. The step states that "Blending may be PERFORMED for routine LLRW such as resins and filter media..." The mixture is required to be in conformance with the guidance provided in the NRC's Branch Technical Position on Concentration Averaging and Encapsulation and further clarified in the NRC's Branch Technical Position on Blending of Low-Level Radioactive Waste, SECY-10-0043.

Step 4.2.15. was added to the document. The step states that "Encapsulation may be PERFORMED for routine wastes such as filters, filter cartridges, or sealed sources centered in an encapsulated mass..." The encapsulated mass is required to be in conformance with the guidance provided in the NRC's Branch Technical Position on Concentration Averaging and Encapsulation, January 1995.

e.Step 4.6.3.was modified to provide an itemized list that details the methodology for implementation of various process control procedures at LaSalle Station. Detail regarding the implementation of vendor dewatering procedures was also added.

f.Definitions for Concentration Averaging (Step 2.11.), Encapsulation (Step 2.12.), and Blending (Step 2.13.) were added. These definitions were added to provide additional clarification for the terms used in several new Steps (4.2.13 through 4.2.15.) in the body of the procedure.

g.Two (2) new references were added to the procedure and are listed below:Step 6.2.7.

Amendment No. 202 to Facility Operating License No. NPF-11 and Amendment No. 189 to Facility Operating License (FOL) No. NPF-18 for the LaSalle County Station (LSCS), Units 1 and 2Step 6.2.8.

NRC Branch Technical Position on Blending of Low-Level Radioactive Waste, SECY- 10-0043 h.Numerous minor wording and editorial changes were made throughout the document to correct grammatical errors and to improve the document's clarity.

The Plant Operating Review Committee (PORC)unanimously approved Revision 10 of RW-AA-100, Process Control Program for Radioactive Wastes.

There were no changes to the Process Control Program processing systems or components. There was no use of a solidification agent (e.g. cement, urea formaldehyde, etc.) during the processing of solid radioactive waste.

8.Effluent Monitoring Instrumentation time clocks and sample anomalies.

a.Time clocks:

The U2 Division 2 Residual Heat Removal Service Water Process Radiation Monitor exceeded the LaSalle Station ODCM 30 day time clock for inoperability on 12/26/14 @ 12:11. Once the 30 day Page 5 of 78 LASALLE COUNTY NUCLEAR POWER STATION EFFLUENT AND WASTE DISPOSAL ANNUAL REPORT (2014)

SUPPLEMENTAL INFORMATION time clock expired, ODCM 12.2.1 Condition G.1 was entered. Condition G.1 states: "Explain why the inoperability was not corrected in a timely manner in the next Radioactive Effluent Release Report".

The U2 Division 2 (Div 2) Residual Heat Removal (RHR) Service Water Process Radiation Monitor (PRM) was declared inoperable (INOP) on 11/26/14 @ 12:11 due to loss of alarm function during the performance of LaSalle Station surveillance LIS-RH-205B, UNIT 2 RHR B SERVICE WATER EFFLUENT RADIATION MONITOR CALIBRATION. Following the declaration of the PRM inoperable, the appropriate ODCM time clocks were entered. ODCM REC 12.2.1 Condition E. requires grab samples be pulled for isotopic analysis once per 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> and analyzed for principal gamma emitters and I-131 when pump flow is present in the system.

All appropriate ODCM sampling was performed during the PRM period of inoperability.

Following the declaration of the PRM INOP, work was progressing toward restoring the PRM to operable status.

However, on 12/12/14 @ 11:45 a through wall leak was identified on the U2 Div 2 RHR Service Water piping. The leak was located at the point where the suction piping for the U2 Div 2 RHR Service Water PRM meets the U2 "B" RHR Heat Exchanger discharge piping.

Although the RHR Service Water leak had no impact on the function or operability of the PRM, it did delay PRM repair work. The PRM was isolated to allow the appropriate piping repair to be completed. Due to the time necessary to complete the piping repair and the time that has already elapsed, the 30 day ODCM time clock was exceeded on 12/26/14 @ 12:11. Following the repairs to the PRM alarm function (source check mechanism) and the appropriate piping repairs, the PRM was restored to operable status on 1/8/2015 @ 2040.

b.Sample anomalies:

There were no sampling anomalies affecting the measurement of effluents experienced during 2014, 9.Offsite Dose Calculation Manual Revisions.

There were no ODCM revisions issued during 2014.

10.Independent Spent Fuel Storage Installation (ISFSI).

An Independent Spent Fuel Storage Installation (ISFSI) campaign began in 2010 when used fuel was removed from the Spent Fuel Pool (SFP), placed into three (3) casks, and transferred to an outdoor concrete storage pad. Three (3) additional casks were placed on the pad in 2011. No casks were placed on the pad in 2012. Five (5) additional casks were placed on the pad in 2013. Five (5) additional casks were placed on the pad in 2014. The total number of casks currently stored on the ISFSI pad is sixteen (16). There were no radioactive effluents released from the LaSalle ISFSI during the first three months of 2015, during 2014, or during any previous year.

Revision 10 of the Process Control Procedure (RW-AA-100) was implemented on January 15, 2014. A copy of Revision 10 has been included as Appendix A to this report. A summary of the changes in Revision 10 are described below:Step 4.2.9.2. was modified to include WCS (Waste Control Specialists LLC) located in Andrews, TX as a storage/disposal facility and as a HIC (High Integrity Container) supplier.Step 4.2.13. was added to the document. The step states that "Concentration averaging may be PERFORMED to combine LLRW [Low Level Radioactive Wastes]

having different concentrations to form a homogeneous mixture..." The mixture is required to be in conformance with the guidance provided in the NRC's Branch Technical Position on Concentration Averaging and Encapsulation, January 1995.Step 4.2.14. was added to the document. The step states that "Blending may be PERFORMED for routine LLRW such as resins and filter media..." The mixture is required to be in conformance with the guidance provided in the NRC's Branch Technical Position on Concentration Averaging and Encapsulation and further clarified in the NRC's Branch Technical Position on Blending of Low-Level Radioactive Waste, SECY-10-0043.Step 4.2.15. was added to the document. The step states that "Encapsulation may be PERFORMED for routine wastes such as filters, filter cartridges, or sealed sources centered in an encapsulated mass..." The encapsulated mass is required to be in conformance with the guidance provided in the NRC's Branch Technical Position on Concentration Averaging and Encapsulation, January 1995.Step 4.6.3.was modified to provide an itemized list that details the methodology for implementation of various process control procedures at the Site. Detail regarding the implementation of vendor dewatering procedures was also added.Definitions for Concentration Averaging (Step 2.11.), Encapsulation (Step 2.12.), and Blending (Step 2.13.) were added. These definitions were added to provide additional clarification for the terms used in several new Steps (4.2.13 through 4.2.15.) in the body of the procedure.

1.1.1.Establish the process and boundary conditions for the preparation of specific procedures for processing, sampling, analysis, packaging, storage, and shipment of solid radwaste in accordance with local, state, and federal requirements.(CM-1)1.1.2.Establish parameters which will provide reasonable assurance that all Low Level Radioactive Wastes (LLRW), processed by the in-plant waste process systems on-site OR by on-site vendor supplied waste processing systems, meet the acceptance criteria to a Licensed Burial Facility, as required by 10CFR Part 20, 1OCFR Part 61, 1OCFR Part 71, 49CFR Parts 171-172, "Technical Position on Waste Form (Revision 1)" [1/91], "Low-Level Waste Licensing Branch Technical Position on Radioactive Waste Classification" [5/83], and the Station Technical Specifications, as applicable.

1.1.3.Provide reasonable assurance that waste placed in "on-site storage" meets the requirements as addressed within the Safety Analysis Reports for the low level radwaste storage facilities for dry and/or processed wet waste.

2.TERMS AND DEFINITIONS 2.1.Process Control Program (PCP): The program which contains the current formulas, sampling, analysis, tests, and determinations to be made to ensure that processing and packaging of solid radioactive waste based on demonstrated processing of actual or simulated wet solid wastes will be accomplished in such a way as to assure the waste meets the stabilization criteria specified in 10CFR Parts 20, 61 and 71, state regulations, and burial site requirements.

2.2.Solidification:

Liquid waste processed to either an unstable or stable form per 1 OCFR61 requirements. Waste solidified does not have to meet the 300-year free standing monolith criteria. Approved formulas, samples and tests do not have to meet NRC approval for wastes solidified in a container meeting stability criteria (e.g.

High Integrity Container).

2.3.Stabilization:

Liquid waste processed to a "stable state" per 10CFR61 Requirements. Established formulas, samples, and tests shall be approved by the NRC in order to meet solidification "stabilization" criteria. This processing method is currently not available, because the NRC recognizes that waste packed in a High Integrity Container meets the 300-year stabilization criteria. In the event that this processing method becomes an acceptable method, then the NRC shall approve the stabilization formulas, samples, tests, etc.

RW-AA-100 Page 2 of 12 2.4.Solidification Media: An approved media (e.g. Barnwell - vinyl ester styrene, cement, bitumen) when waste containing nuclides with greater than 5-year half lives is solidified in a container with activity greater than 1 micro curie/cc.

Waste solidified in a HIC is approved by the commission meeting the 10CFR61 stabilization criteria, including I% free standing liquids by volume when the waste is packaged to a"stable" form and < 0.5% when waste is packaged to an "unstable" form. The formulas, sampling, analysis, and test do not require NRC approval, because the HIC meets the stability criteria.

2.4.1.Solidification to an unstable or stable state is performed by vendors, when applicable. Liquid waste solidified to meet stabilization criteria (10CFR61 and 01-91 Branch Technical Requirements) shall have documentation available that demonstrates that the process is approved by the NRC or disposal facility.

2.5.Dewatering:

The process of removing fluids from liquid waste streams to produce a waste form that meets the requirements of 10CFR Part 61 and applicable burial site criteria, <0.5% by volume when the waste is packaged to an "unstable" state, or

<1 % by volume when the waste is packaged to a "stable" form.

2.6.High Integrity Container (HIC): A disposable container that is approved to the Requirements of 10CFR61. The use of HIC's is an alternative to solidification or encapsulation in a steel container to meet burial stability. HIC's are used to package dewatered liquid wastes, (e.g. filter cartridges, filter media, resin, sludges, etc), or dry active waste.

2.7.Liquid Waste Processing Systems:

In-plant or vendor supplied processing systems consisting of equipment utilized for evaporation, filtration, demineralization, dewatering, compression dewatering, solidification, or reverse osmosis (RO) for the treatment of liquid wastes (such as Floor Drains, Chemical Drains and Equipment Drain inputs).

2.8.Incineration, RVR, and/or Glass Vitrification of Liquid or Solid: Dry or wet waste processed via incineration and/or thermal processing where the volume is reduced by thermal means meets 10CFR61 requirements.

2.9.Compaction:

When dry wastes such as paper, wood, plastic, cardboard, incinerator ash, and etc. are volume reduced through the use of a compactor.

RW-AA-100 Page 3 of 12 2.10.Waste Streams:

Consist of but are not limited to

-Filter media (powdered, bead resin and fiber),-Filter cartridges,-Pre-coat body feed material,-Contaminated charcoal,-Fuel pool activated hardware,-Oil Dry absorbent material added to a container to absorb liquids

-Fuel Pool Crud

-Sump and tank sludges,-High activity filter cartridges,-Concentrated liquids,-Contaminated waste oil,-Dried sewage or wastewater plant waste,-Dry Active Waste (DAW): Waste such as filters, air filters, low activity cartridge filters, paper, wood, glass, plastic, cardboard, hoses, cloth, and metals, etc, which have become contaminated as a consequence of normal operating, housekeeping and maintenance activities.

-Other radioactive waste generated from cleanup of inadvertent contamination.

2.11.Concentration Averaging:

Concentration averaging is either: a) the mathematical averaging of waste concentrations, based on the size, geometry, type of radioactive emission, and observed dose rates, or b) the combining of radioactive components in a single container and how their radioactivity may be averaged over the volume of the container. Concentration averaging is subject to constraints identified in the NRC's Branch Technical Position on Concentration Averaging and Encapsulation and may also be constrained by Agreement States or Disposal Facilities.

2.12.Encapsulation:

Encapsulation is the surrounding of a radioactive source or component with a nonradioactive material. Encapsulation involves a radioactive core surrounded by a non-radioactive matrix.

2.13.Blending: The intentional mixing of different, but miscible waste streams (such as resins, filter media, etc.) from different batches or systems for the purpose of operational efficiency or ALARA. Blending applies to LLRW streams only. The addition of non-radioactive materials or fillers is not considered blending.

RW-AA-100 Page 7 of 12 4.2.13.Concentration averaging may be PERFORMED to combine LLRW having different concentrations of radionuclides to form a homogeneous mixture in accordance with the guidance in the NRC's Branch Technical Position on Concentration Averaging and Encapsulation-1995:

For homogeneous waste types such as resins and filter media, the concentration of the mixture for classification purposes may be based on either the highest radionuclide concentration in any of the individual waste types contributing to the mixture or the volumetric or weight-averaged nuclide concentrations in the mixture provided that the concentrations of the individual waste type contributors to the mixture are within a factor of 10 of the average concentration of the resulting mixture. (NOTE: a designed collection of homogeneous waste types (from different sources within a facility) is not considered `mixing' and the concentration for classification purposes may be the average concentration of the combination).

For non-homogeneous waste types such as activated metals, cartridge filters or components incorporating radioactivity in their design, the concentration should be determined from the total weight or displaced volume (excludingmajor void spaces) of the component. Mixtures of components in a disposal container is permissible. Concentration averaging of a mixture of components of similar types can be performed in accordance with the NRC's Branch Technical Position on Concentration Averaging and Encapsulation and any State or Disposal Site specific requirements.

4.2.14.Blending may be PERFORMED for routine LLRW such as resins and filter media in accordance with the guidance in the NRC's Branch Technical Position on Concentration Averaging and Encapsulation as further clarified in SECY 2010-0043.

The concentration of the mixture may be determined based on the total activity of allcomponents in the mixture divided by the total volume or mass of the mixture.

Reasonable effort should be made to mix blended LLRW so that activity is evenly distributed.

4.2.15.Encapsulation may be PERFORMED for routine wastes such as filters, filter cartridges, or sealed sources centered in an encapsulated mass, in accordance with the guidance in the NRC's Branch Technical Position on Concentration Averaging and Encapsulation. Classification may be based on the overall volume of the final solidified mass provided that;

-The minimum solidified volume or mass should be reasonably difficult to move by hand.

-The maximum solidified volume or mass used for determining concentration for any single discrete source should be no more than 0.2 m3 or 500Kg (typically 55-gallon drum).

-The maximum amount of gamma-emitting radioactivity or radioactive material is <0.02 mrem/hr on the surface of the encapsulation over a 500-year decay period.

RW-AA-100Revision 10 Page 8 of 12 The maximum amount of any radionuclide in a single encapsulation, when averaged over the waste and encapsulating media, does not exceed the maximum concentration limits for Class C waste.

Written procedures should be established to ensure that the radiation source(s) is reasonably centered (or distributed) within the encapsulating media.All other disposal facility requirements for encapsulated material are met.

4.3.Burial Site Requirements 4.3.1.Waste sent directly to burial shall COMPLY with the applicable parts of 49CFR171-172, 10CFR61, 10CFR71, and the acceptance criteria for the applicable burial site.

4.4.Shipping and Inspection Requirements 4.4.1.All shipping/storage containers shall be INSPECTED, as required by station procedures, for compliance with applicable requirements (Department of Transportation (DOT), Nuclear Regulatory Commission (NRC), station, on-site storage, and/or burial site requirements) prior to use.

4.4.2.Containers of solidified liquid waste shall be INSPECTED for solidification quality and/or dewatering requirements per the burial site, offsite vendor acceptance, or station acceptance criteria, as applicable.

4.4.3.Shipments sent to an off site processor shall be INSPECTED to ensure that the applicable processor's waste acceptance criteria are being met.

4.4.4.Shipments sent for off site storage shall MEET the storage site's waste acceptance criteria.4.5.Inspection and Corrective Action 4.5.1.Inspection results that indicate non-compliance with applicable NRC, State, vendor, or site requirements shall be IDENTIFIED and TRACKED through the Corrective Action Program.

4.5.2.Administrative controls for preventing unsatisfactory waste forms from being released for shipment are described in applicable station procedures. If the provisions of the Process Control Program are not satisfied, then SUSPEND shipments of defectively packaged radioactive waste from the site.(CM-1)4.5.3.If freestanding water or solidification not meeting program requirements is observed, then samples of the particular series of batches shall be TAKEN to determine the cause. Additional samples shall be TAKEN, as warranted, to ensure that no freestanding water is present and solidification requirements are maintained.

RW-AA-100 Page 9 of 12 4.6.Procedure and Process Reviews 4.6.1The Exelon Nuclear Process Control Program and subsequent changes (other than editorial/minor changes) shall be REVIEWED and APPROVED in accordance with the station procedures, plant-specific Technical Specifications (Tech Spec), Technical Requirements Manual (T&RM), Operation Requirements Manual (ORM), as applicable, for the respective station and LS-AA-106. Changes to the Licensees Controlled Documents, UFSAR, ORM, or TRM are controlled by the provisions of 1 OCFR 50.59.

4.6.2.Any changes to the PCP shall be reviewed to determine if reportability is required in the Annual Radiological Effluent Release Report (ARERR). The Radwaste Specialist shall ensure correct information is SUBMITTED to the ODCM program owner prior to submittal of the ARERR.
