Callaway Energy Center 2014 Annual Radioactive Effluent Release Report Callaway Energy Center 2014 Annual Abstract Radioactive The Annual Radioactive Effluent Release Report covers the operation of Efluent Release the Callaway Energy Center during the year Report 2014. The report includes a summary of the quantities of Facility Operating License NPF-30 radioactive liquid and Docket No. 50-483 gaseous effluents and solid waste released

1. Introduction This Annual Radioactive Effluent Release Report (ARERR) is submitted from the unit. The by Union Electric Co., dba Ameren Missouri, in accordance with the report also includes an requirements of 10 CFR 50.36a and Callaway Energy Center Technical annual summary of Specification 5.6.3. This report is for the period January 1, 2014 to December 31, 2014. hourly meteorological data collected during the The doses to the Member of the Public from all liquid and gaseous effluents discharged during the reporting period were small fractions year and an assessment of the NRC and EPA regulatory limits and the Radioactive Effluent of radiation dose to the Control limits in the Offsite Dose Calculation Manual.

Member of the Public To maximize consistency, aid in the review by Members of the Public, from liquid and gaseous and to allow easier industry- wide comparison of the data, this report effluents. 1 is presented in the format recommended by Regulatory Guide 1.21, revision 2, insofar as is practicable. Callaway is committed to revision

Callaway Energy Center 2014 Annual Radioactive Effluent Release Report 1 of Regulatory Guide 1.21, and some of the information is not readily available in the format recommended by revision 2.

2. Gaseous Effluents The quantity of radioactive material released in gaseous effluents during the reporting period is summarized in Table A-1. The quarterly and annual sums of all radionuclides discharged in gaseous effluents are reported in Tables A-1A and A-1B. All gaseous effluent releases are considered to be ground level.

The quantity of 14C released in gaseous effluents was calculated as described in EPRI Technical Report 1021106 1.

3. Liquid Effluents The quantity of radioactive material released in liquid effluents during the reporting period is summarized in Table A-2. The quarterly and annual sums of all radionuclides discharged in liquid effluents are reported in Table A-2A. All liquid effluents were discharged in batch mode; there were no continuous liquid discharges for the reporting period. Dilution by the Missouri River, in the form of the near- field dilution factor, is utilized in the ODCM dose calculation methodology.
4. Solid Waste Storage and Shipments The volume and activity of solid waste shipped for disposal is provided in Table A-3. Table A-3 is presented in the format of rev. 1 to Regulatory Guide 1.21 because the data is not readily available in the format recommended by rev. 2 to Regulatory Guide 1.21.
5. Dose Assessments The annual evaluation of dose to the Member of the Public is calculated in accordance with the methodology and parameters in the ODCM 2 and is reported in Tables A-4 and A-5. The dose to the Member of the Public was calculated using the re- evaluated long- term meteorological dispersion parameters 3,4.

Callaway Energy Center 2014 Annual Radioactive Effluent Release Report 5.1 Table A-4, Dose Assessments, 10 CFR 50, Appendix I The dose assessments reported in Table A-4 were calculated using the methodology and parameters in the ODCM and demonstrate compliance with 10 CFR 50, Appendix I. The gamma air dose and beta air dose were calculated at the nearest Site Boundary location with the highest value of X/Q, as described in the ODCM. The maximum organ dose from gaseous effluents was calculated for the ingestion, inhalation, and ground plane pathways at the location of the nearest resident with the highest value of D/Q, as described in the ODCM. The organ dose does not include the dose from 14C, which is listed separately.

5.2 Table A-5, EPA 40 CFR 190 Individual in the Unrestricted Area The dose assessments reported in Table A-5 are the doses to the Member of the Public from activities within the Site Boundary plus the doses at the location of the Nearest Residence. A large portion of the residual land of the Callaway Site is managed by the State of Missouri Conservation Department as the Reform Wildlife Management Area. Pursuant to the guidance provided in Regulatory Guide 1.21, rev.2, the dose reported in Table A-5 is the sum of the dose from gaseous effluents (at the Nearest Resident location and within the Site Boundary), plus the dose contribution due to activities within the Site Boundary and the organ dose from inhalation of 14C (at the Nearest Resident location and within the Site Boundary). The dose assessments in Table A-5 demonstrate compliance with 10 CFR 20.1301(e) and 40 CFR 190.

6. Supplemental Information 6.1 Abnormal Releases or Abnormal Discharges The Limited Site Investigation for leakage of liquid radioactive effluent from manhole 86-2 is described in Appendix D. This issue is documented in CAR 201405071.

6.2 Non- routine Planned Discharges There were no non- routine planned discharges during the reporting period.

6.3 Radioactive Waste Treatment System Changes There were no major changes to the liquid or gaseous radwaste treatment systems during the reporting period.

6.4 Annual Land Use Census Changes Changes in sample locations identified in the Land Use Census are described in the Annual Radioactive Environmental Operating Report.

6.5 Effluent Monitoring System Inoperability There were no effluent radiation monitors out of service for periods in excess of the Limiting 3 Condition for Operation and associated Action statements.

Callaway Energy Center 2014 Annual Radioactive Effluent Release Report 6.6 Offsite Dose Calculation Manual Changes There were no changes to the Offsite Dose Calculation Manual during the reporting period.

6.7 Process Control Program Changes There were no substantive changes to APA-ZZ-01011, Process Control Program during the reporting period.

6.8 Corrections to Previous Reports Errors were discovered in the setup parameters for the VAXMET computer code used to calculate the dispersion parameters for the Annual Radioactive Effluent Release Reports for the period 1993- 2013. This apparently occurred during the 1993 computer system upgrade when the setup files were transferred to the new system. The transfer of the file with the Terrain Recirculation Correction Factors was offset by one row which affected the X/Q and D/Q calculations. During investigation of this issue it was discovered that the vent height parameter and the terrain height parameters were also in error. These issues are described in the Callaway Energy Center corrective action system. 5,6,7 The correct parameters were researched, reviewed, and formally documented in calculation HPCI 1503. The dispersion parameters for each year 1993- 2013 were recalculated with the NRC computer code XOQDOQ 8 and the parameters in HPCI 1503. The doses from gaseous effluents were recalculated using the recalculated dispersion parameters. The revised gaseous effluent doses are provided in Appendix C. The dose tables are presented in the format in which they were originally submitted.

The quantities discharged were not affected. The dose from liquid effluents and the dose from 14 C was not affected.

6.9 Other Information Related to Radioactive Effluents Meteorological Joint Frequency Tables for the monitoring period are provided in Appendix B.

The long- term meteorological data was re- evaluated using the data for the years 2009-2013. 9,10 Changes were identified in the locations for dose calculation due to changes in the calculated dispersion parameters and the ODCM was revised accordingly. 11 5

Callaway Energy Center 2014 Annual Radioactive Effluent Release Report Appendix D Leakage from Manhole 86-2 Limited Site Investigation Event Description 25 The original Techite 26 plant discharge line was replaced in 2007 with a new high density polyethylene (HDPE) line constructed approximately parallel to the old line. This pipeline carries cooling tower blowdown and liquid radioactive effluent to the Missouri River. The discharge point is ~400 feet downstream of the plant intake structure. The Techite piping that connected the cooling tower blowdown to the new HDPE plant discharge pipeline was not replaced at that time.

The Techite piping that connected the cooling tower blowdown to the plant discharge pipeline was replaced in 2010 with 18" HDPE and connected to the HDPE plant discharge line. The connection was made via new manhole 86-2 (MH86-2). MH86-2 also provides a connection with the 6" stainless steel (SS) liquid radwaste discharge pipe. The liquid radwaste discharges into MH86-2 where it mixes with the cooling tower blowdown prior to being transported to the river by the ~6 mile long plant discharge line. The HDPE piping penetrations were installed with an anchor/ water stop, essentially a collar or ring, cast in place with the concrete manhole to prevent leakage from the penetration. MH86-2 is coated with a waterproofing elastomeric polyurethane bonded geotextile system. The coating system has a waterproofing function to protect the concrete and it provides a secondary barrier to prevent leakage through the concrete structure. The coating was applied to the interior and exterior surfaces of the manhole.

The coating was not intended to provide primary waterproofing of the piping penetrations.

Issues with shredding of the waterproof coating inside MH86-2 were first identified on November 1, 2012 while troubleshooting reduced plant discharge pipeline flow rate. An October, 2013 self-assessment of Callaway's groundwater protection program by a team of EPRI experts, an industry peer and Callaway personnel identified the degraded coating in MH86-2 as a gap with respect to NEI 07-07, "Industry Groundwater Protection Initiative- Final Guidance" and recommended installation of a sentinel well to monitor for possible leaks.

On July 22, 2014, monitoring well U1MW-031 was installed as a sentinel well to monitor for possible leakage from MH86-2. Well development was completed on July 25, 2014 and the first sample was taken the same day. On July 31, 2014, the vendor lab notified Callaway that the 3H concentration in the sample was 1.6E6 pCi/L and 60Co was present at 12 pCi/L. Subsequent samples showed only 3H.

Callaway Energy Center 2014 Annual Radioactive Effluent Release Report All liquid radwaste discharges were suspended. A four hour voluntary notification was made to the NRC Operations Center pursuant to NEI 07-07. Notifications were also made to the Missouri Department of Natural Resources, NRC Resident Inspector, NRC Region IV Office, Callaway County Presiding Commissioner, Nuclear Energy Institute, and American Nuclear Insurers.

The manhole was visually inspected on August 1, 2014. The inspection revealed a failure of the seals around the HDPE plant discharge piping penetration and the 6" SS radwaste discharge line penetration. Hydrophobic polyurethane foam (Blome Sealant 78 27) was injected into injection ports drilled around the HDPE plant discharge piping penetration and also behind the link seals on the 6 SS radwaste discharge line penetration.

Four different fluorescent dye tests were performed to demonstrate that the seal repairs were effective. Liquid radwaste discharges recommenced on August 15, 2015 and two additional dye tests were performed. On August 28, 2014, the 6" SS radwaste discharge piping was extended through the manhole and about 65" down the HDPE plant discharge line, thus bypassing MH86-2.

Cause Analysis A formal root cause evaluation was performed for this event. The gaps between the HDPE plant discharge pipeline and the concrete wall of the manhole are the result of inadequate bearing capacity of the bedding material. The HDPE plant discharge pipeline was inserted into the manhole before the bedding material was fully in place resulting in the challenge of placing and compacting the bedding material under the pipe. The bedding material is more critical than in typical applications due to close proximity to the rigid manhole wall penetration seals that are intolerant to movement and the ~25' bury depth results in significant overburden loading. The inadequate bedding compaction and significant overburden loading allowed for settlement and rotation of the pipe which sheared the water stops, deformed the pipe, and caused gaps to develop. The 6" SS radwaste discharge pipe experienced similar issues due to inadequate bedding and significant overburden loading resulting in compression of the rubber portion of the Link- Seals 28.

Activity Concentration It is assumed the leakage began at the time of construction and lasted until discovery so that the duration of the leakage is assumed to be approximately 4 years. The volume of leakage is unknown therefore the total activity leaked is unknown. The average 3H concentration in the leakage can be obtained from the Annual Radioactive Effluent Release Report for the subject years as shown in TABLE 1.

The soils are underlain by weathered sedimentary rocks with horizontal to sub- horizontal fracture orientations.

Across the plateau, the Graydon Chert Formation is considered to be the shallow aquifer. There are localized areas where the overlying material may be included in this aquifer, but in general the saturated groundwater is confined within the chert. The chert is a moderate water-bearing unit, with the glacial till acting as the confining unit above the chert and the Burlington Limestone acting as the confining unit and top of the aquitard beneath the chert. The Graydon Chert lies unconformably atop the Burlington Limestone and unconformably below the glacial till, therefore, its elevation and thickness vary. Across the plateau, the depth of the Graydon Chert ranges from 15' to 39' below ground surface (bgs) and averages approximately 27' bgs. Its thickness ranges from 16' to 61' and averages approximately 38'.

Groundwater within the Graydon Chert conglomerate flows radially outwards in the vicinity of the plant towards the nearby drainage basins that surround the plateau. The impact of the discharge lines bedding material on the overall groundwater flow directions within this hydrogeologic unit cannot be quantified but is likely to be limited. Localized variations in groundwater flow directions are anticipated within the conglomerate when it is in direct contact with the bedding material. In the vicinity of the plant discharge pipeline and the abandoned 29 "Final Groundwater Model Report Callaway Nuclear Power Plant", rev. 1, October 31, 2008. Paul C. 119 Rizzo Associates, Inc.

30 "Tritium Investigation Report Callaway Energy Center Fulton, Missouri", March 9, 2015. GZA GeoEnvironmental, Inc.

Callaway Energy Center 2014 Annual Radioactive Effluent Release Report Techite pipeline, hereinafter collectively called "pipelines", groundwater elevations in the conglomerate are generally greater than the groundwater levels in the bedding material for the Techite pipeline down line. Therefore, convergent flow from the conglomerate into the bedding material for the Techite pipeline is anticipated.

Beneath the shallow aquifer there is a leaky, confining aquitard. The top of the aquitard begins with the top of the Burlington Limestone and extends through the Bushberg Sandstone, Snyder Creek Formation (shale), Callaway Limestone, and upper portion of the Cotter-Jefferson City (CJC) Dolomitic Limestone. The depth to the top of the aquitard averages 68' bgs across the plateau, and its thickness is approximately 290' in the central portion of the plateau.

Beneath the aquitard is the CJC aquifer. The depth to the CJC aquifer is approximately 350' bgs in the central portion of the plateau. The thickness of the CJC aquifer beneath the plateau is approximately 300'. Regionally, the CJC aquifer is considered to be a minor aquifer and represents the top of the Cambrian-Ordovician aquifer system, which consists of intervals of minor aquifers and major aquifers with intermittent aquitards to depths up to 2,000' bgs.

Groundwater within the CJC aquifer flows radially outwards from the plateau to the nearby drainage basins that surround the plateau. The hydraulic head within the CJC aquifer are approximately 250' lower than the shallower overburden and Graydon Chert conglomerate hydrogeologic units. As such, the groundwater elevation data, as well as the sub- horizontal fracture orientations, indicate that the communication between the shallower groundwater and the CJC aquifer is limited. The pipelines bedding material is not likely to influence the groundwater flow directions with the CJC aquifer.

The well yield for the chert aquifer is less than 1 gallon per minute (gpm) and for the CJC aquifer is approximately 5 to 10 gpm. Two pumping tests were performed successfully in the CJC aquifer, and the relatively low estimates of storativity are consistent with mildly fractured bedrock aquifers where the small size of fractures and low degree of interconnectedness limits the amount of water in storage and the amount of water to potentially yield to a well. A step-drawdown test at a pumping well in the chert aquifer resulted in a dry well after a short period of time, which made the pumping test unviable.

Groundwater primarily flows within bedrock along fractures and bedding/ joint planes.

Therefore, the magnitude of vertical flow within bedrock is directly related to the interconnection of multiple fractures, as well as fracture orientations. The fractures orientations near Callaway are sub- horizontal and the Rock Quality Designation (RQD) Index of the deeper core runs were typically greater than 70%. This information, coupled with the groundwater elevation data collected during the recent Limited Site Investigation (LSI) as well as historical 120 data, suggest that a good hydraulic communication does not exist between the shallow sedimentary bedrock and the deeper CJC aquifer. The numerous springs which are located near

Callaway Energy Center 2014 Annual Radioactive Effluent Release Report the base of the plateau and along the slope of the plateau indicate that groundwater preferentially flows along the sub- horizontal fractures in shallow bedrock and discharges at these spring locations, prior to reaching the CJC aquifer. Therefore the amount of vertical flow between the shallow and deeper rock is limited.

Within the Missouri River flood plain, the upper 10'- 15' of the overburden sediments consists of mottled brown and red silty clay alluvial deposits. These fine grained soils were underlain by fine to coarse sand and gravel. Groundwater within the alluvial floodplain deposits flows to the south- southeast, towards the Missouri River. The groundwater elevation data indicate that the shallow groundwater in the northeastern portion of the flood plain discharges into Logan Creek, a small tributary of the Missouri River. Because the hydraulic conductivity of the native alluvial sediments is similar to the bedding material, the influence of the pipelines trenches on overall groundwater flow directions is minimal. As such, dissimilar to conditions on the plateau, groundwater within the bedding material may potentially exfiltrate into the native sand and gravel sediments.

Limited Site Investigation 31 A Limited Site Investigation (LSI) was performed to determine the migration pathway and fate of the 3H contamination. The LSI concluded that, on the plateau, the 3H impacted water has not migrated beyond the confines of the HDPE plant discharge pipeline trench and the abandoned Techite pipeline trenches. Other than the pipeline bedding, 3H was not detected in any of the monitoring wells screened in the overburden or bedrock on the plateau. Water exfiltrating from the abandoned Techite pipeline in the Missouri River alluvial floodplain follows natural groundwater flow paths through both the sand and bedding before discharging to the river.

Twenty eight (28) wells were installed during the LSI. The LSI concluded that the 3H leaked from the damaged seals in MH86-2 flows down the bedding of the HDPE discharge pipeline for approximately 1000'. At that point, the 3H impacted water followed the bedding material of an abandoned 12" pipe which is hydraulically connected to the bedding material of the abandoned Techite plant discharge line.

The Techite discharge pipeline was abandoned in 2007 when the new HDPE plant discharge pipeline was installed, however the abandoned Techite pipeline was not filled in or plugged.

Some of the 3H impacted water enters the Techite pipeline at abandoned manhole 86-4A through unsealed penetrations for the abandoned 12" pipe; the rest migrates down pipe through the bedding material of the abandoned Techite pipeline. Continued infiltration of 3H impacted water through the leaky bell and spigot joints into the Techite pipeline likely occurs 121 31 "Tritium Investigation Report Callaway Energy Center Fulton, Missouri", March 9, 2015. GZA GeoEnvironmental, Inc.

Callaway Energy Center 2014 Annual Radioactive Effluent Release Report over approximately the next mile and then migrates within the Techite pipeline to the edge of the plateau.

An inward hydraulic gradient into the pipeline bedding material effectively confines the 3H impacted water to the bedding material and interior of the abandoned Techite pipeline and likely prevents it from leaking out through the leaky joints. As a result, clean overburden water continues to flow into the bedding material from the surrounding soil.

Near the plant, the HDPE and Techite pipelines were constructed in separate trenches excavated through the low permeability soil. The sides and bottom of the trenches are therefore in this portion of the alignment. In portions of the alignment near the edge of the plateau, the pipelines were installed in trenches over or excavated within shallow bedrock.

On the plateau, water inside the abandoned Techite pipeline remains in the pipe because the water level in the pipe is lower than the surrounding groundwater elevation. Thus, the hydraulic gradient is from the surrounding overburden towards the abandoned Techite discharge line and the surrounding bedding material. The 3H impacted water has not migrated significantly beyond the confines of the discharge pipeline trenches on the plateau. Other than the discharge pipeline bedding, 3H was not detected in any of the monitoring wells screened in the overburden or bedrock on the plateau.

Within the Missouri River valley deposits, the gate valve on the abandoned Techite pipeline is permanently closed and the downstream pipe is cut and capped. As such, the 3H impacted water exfiltrates through the leaky bell and spigot joints of the abandoned Techite pipeline within the Missouri River floodplain when the water level in the abandoned Techite pipeline is higher than the groundwater elevation of the surrounding bedding material. Once the water exfiltrates from the pipe, it flows through the overburden to the river along the natural groundwater flow paths. In the pipeline corridor, those natural groundwater flow paths would likely be influenced by the bedding of the pipeline (i.e., localized convergent flow towards the bedding may exist) when the water level is above the bottom of the pipeline trench. However, the water level may be below the bottom of the bedding in portions of the floodplain. As such, the natural groundwater flow paths are likely through both the sand and bedding before discharging at the river. The abandoned Techite pipeline valve vault is ~340' from the Missouri River shoreline and is ~500' from the normal liquid effluent discharge point.

Monitoring Results The monitoring results are summarized in Table 2.The 3H analytical results for each sample are presented in Table 3. The gamma spectroscopy results and drawings showing the well locations are provided in the 2014 Annual Radiological Environmental Operating Report. 122

Callaway Energy Center 2014 Annual Radioactive Effluent Release Report Dose to the Member of the Public The dose to the Member of the Public was calculated for each discharge and was reported in the Annual Radioactive Effluents Release Report for the respective year. As described above, the portion of each release that leaked from MH86-2 into the pipelines trenches was conveyed by the abandoned Techite pipeline to the Missouri River alluvial floodplain to a location ~340 feet from the Missouri River shoreline where it followed natural groundwater flow patterns to the Missouri River. The highest measured 3H concentration in the Missouri River floodplain (U1MW-047) was 8,512 pCi/L, which, if it were the sole source of drinking water for a year, would deliver a dose of approximately 1.7 mrem. However, the groundwater in the Missouri River floodplain is not a drinking water source. The original dose calculations bound the dose to the Member of the Public from this discharge.

Ameren owns ~7,200 acres surrounding the plant site and extending to the northern bank of the Missouri River. The site groundwater including the groundwater in the pipelines corridor is not used for irrigation and there are no drinking water wells in the Missouri River alluvial floodplain for at least a mile downstream. There are no new dose pathways created by this discharge.

The CJC aquifer and the deeper Derby- Doe Run aquifer are important sources of area drinking water. Callaway has been monitoring these aquifers and drinking water from the town of Portland, MO for over 30 years. Callaway installed an additional well at the base of the plateau in 2006 to provide additional monitoring for the CJC aquifer. 3H has never been detected in any of these samples, including during the monitoring events conducted since the release occurred.

Callaway has been monitoring drinking water wells from adjoining properties since 2006 and the monitoring frequency of these wells was increased for the period of the study after the tritium was detected in the groundwater samples from well U1 MW-031. 3H has never been detected in any of the samples collected from these drinking water wells.

Sentinel wells were installed between the pipelines corridor and adjoining properties in 2006. 3H has never been detected in any of these samples.

A network of monitoring wells was installed along the pipelines corridor in 2006- 2010 to monitor for leakage from the pipelines. 3H has never been detected in any of these samples, other than those wells used in the monitoring of the natural attenuation of a 3H contaminated area discovered in 2006. 33 Callaway is currently monitoring the natural attenuation of that area.

That contamination is due to normal operation of the air release valves from when the abandoned Techite discharge line was in operation.

Based on the hydrogeologic conditions within the travel pathway of the release, it is highly unlikely that the impacted water migrated downwards and impacted the much deeper CJC aquifer or other water supply sources near the plant. This conclusion is further supported by the 124 33 CAR 200602748, "Vulnerabilities to Unplanned, Unmonitored Releases Offsite"

Callaway Energy Center 2014 Annual Radioactive Effluent Release Report recent and historical groundwater quality monitoring data for the on- site monitoring wells and off- site water supply wells.

Remedial Actions Following discovery of the leak, all liquid radioactive effluent discharges were suspended until the manhole leaks were repaired. The gaps between the concrete wall of the manhole and the pipe were injected with expanding hydrophobic polyurethane which sealed the leaks. The repairs were tested with fluorescent dye prior to restarting the liquid radioactive effluent discharges.

Actions to Prevent Recurrence The leaks were repaired and tested as described above. In addition, the 6" SS liquid radioactive effluent pipe was extended 65" down the HDPE discharge pipe thus completely bypassing the manhole. Additional testing was performed to ensure these actions are sufficient to prevent leaks.
