Released from TMI During 2014 TMI-1 The attached table presents the maximum hypothetical doses to an individual and the general population resulting from 2014 TMI-1 releases of gaseous and liquid effluents.

Provided below is a brief explanation of the table.A. Liquid (Individual)

Calculations were performed on the four age groups and seven organs recommended in Regulatory Guide 1.109. The pathways considered for TMI-1 were the consumption of drinking water and fish. These two pathways are considered to be the primary recreational activities associated with the Susquehanna River in the vicinity of TMI. The "critical receptor" or Receptor 1 was that individual who 1) consumed Susquehanna River water from the nearest downstream drinking water supplier (Nrightsville Water Supply) and 2) consumed fish residing in the vicinity of the TMI-1 liquid discharge.

For 2014 the calculated maximum whole body (or total body) dose from TMI-1 liquid effluents was 4.57E-3 mrem to an adult (line 1). The maximum organ dose was 4.63E-3 mrem to the liver of an adult (line 2).B. Gaseous (Individual)

There were five major pathways considered in the dose calculations for TMI-1 gaseous effluents.

These were: (1) plume exposure (2) inhalation, consumption of; (3) cow milk, (4) vegetables and fruits and (5) meat.Lines 3 and 4 present the maximum plume exposure at or beyond the site boundary.

The notation of "air dose" is interpreted to mean that these doses are not to an individual, but is considered to be the maximum doses that would have occurred at or beyond the site boundary.

The calculated maximum plume exposures were 1.95E-4 mrad and 7.14E-5 mrad for gamma and beta, respectively.

The maximum organ dose due to the release of iodines, particulates and tritium from TMI-1 in 2014 was 1.10E-1 mrem to the bone of a child. This dose again reflects the maximum exposed organ for the appropriate age group (line 5).For 2014, TMI-1 liquid and gaseous effluents resulted in maximum hypothetical doses that were a small fraction of the quarterly and yearly ODCM dose limits.

Provided below is a brief explanation of the table.A. Liquid (Individual)

Calculations were performed on the four age groups and seven organs recommended in Regulatory Guide 1.109. The pathways considered for TMI-2 were the consumption of drinking water and fish. These two pathways are considered to be the primary recreational activities associated with the Susquehanna River in the vicinity of TMI. The "critical receptor'or Receptor 1 was that individual who 1) consumed Susquehanna River water from the nearest downstream drinking water supplier (Wrightsville Water Supply) and 2) consumed fish residing in the vicinity of the TMI-2 liquid discharge.

For 2014 the calculated maximum whole body (or total body) dose from TMI-2 liquid effluents was 3.87E-4 mrem to an adult (line 1). The maximum organ dose was 6.15E-4 mrem to the liver of a teen (line 2).B. Gaseous (Individual)

There were five major pathways considered in the dose calculations for TMI-2 gaseous effluents.

These were: (1) plume exposure (2) inhalation, consumption of; (3) cow milk, (4) vegetables and fruits and (5) meat.Since there were no noble gases released from TMI-2 during 2014, the gamma and beta air doses (lines 3 and 4, respectively) were zero.The maximum organ dose due to the release of particulates and tritium from TMI-2 in 2014 was 5.63E-5 mrem to the liver, total body, thyroid, kidney, lung, and GI tract of a child (line 5).For 2014, TMI-2 liquid and gaseous effluents resulted in maximum hypothetical doses that were a small fraction of the quarterly and yearly ODCM dose limits.

The estimated dose to a member of the public at or within the TMI Site Boundary was 1.14 mrem for 2014.The following are the assumptions made in this assessment:

Access to the TMI Owner Controlled Area is limited to only those persons who have business related activities that support the operation of the facility.

Therefore, based on the definition of a 'member of the public' in NUREG-1 301, there is no credible scenario for this individual to receive non-occupational dose inside the TMI Owner Controlled Area. The scenario selected will be recreational use of the Susquehanna River and shoreline next to the Owner Controlled Area fence. Based on the two definitions of Site Boundary in the ODCM, this scenario is AT the Site Boundary for liquid releases but INSIDE the Site Boundary for gaseous releases.A member of the public stays next to the owner controlled area for 67 hours7.75463e-4 days <br />0.0186 hours <br />1.107804e-4 weeks <br />2.54935e-5 months <br />. The 67 hours7.75463e-4 days <br />0.0186 hours <br />1.107804e-4 weeks <br />2.54935e-5 months <br /> is based upon Reg. Guide 1.109 shoreline recreation period given in Table E-5. This is a table of recommended values to be used for the maximum exposed individual in lieu of site-specific data. Three Mile Island is co-located with other islands in the Lake Frederick area of the Susquehanna River. This area is used recreationally for boating and fishing over the summer months. The application of the 67 hours7.75463e-4 days <br />0.0186 hours <br />1.107804e-4 weeks <br />2.54935e-5 months <br /> of recreational use from Reg. Guide 1.109 is appropriate.

The highest dose from liquid releases is characterized by release L20140708-075-B.

This release was from the WECST B Radwaste Release Tank. The total body dose from release L20140708-075-B was 3.11 E-4 mrem.The highest dose from a single airborne release is characterized by release G20140211-009-C.

This release was from TMI's Auxiliary and Fuel Handling Buildings ventilation system. The release contained airborne tritium from spent fuel pool evaporation.

This release occurred over 180 hours0.00208 days <br />0.05 hours <br />2.97619e-4 weeks <br />6.849e-5 months <br />. The entire dose from this release will be applied to the 67 hour7.75463e-4 days <br />0.0186 hours <br />1.107804e-4 weeks <br />2.54935e-5 months <br /> recreational use period. The application of the total dose from this release to 67 hours7.75463e-4 days <br />0.0186 hours <br />1.107804e-4 weeks <br />2.54935e-5 months <br /> is conservative.

The maximum individual dose from release G20140211-009-C was 3.35E-3 mrem to the bone of a child.

2014 Annual Radioactive Effluent Release Report for TMI Attachment 8 -Page 2 of 2 The highest fenceline direct radiation result (assumed to be equal to dose) will be added to the dose from the highest liquid and gaseous releases to yield the hypothetical maximum dose to a member of the public within the site boundaries.

The highest fenceline direct radiation result for 2014 was from Station F1-2 and was 37.4 mrem per quarter. The net direct radiation dose, obtained by subtracting the results from a control station dosimeter from the indicator results, was not used. This again is conservative.

Calculations:

37.4 mrem/qtr

  • 1/91.5 d/qtr
  • 1/24 hr/day
  • 67 hr = 1.14 mrem The dose from liquid release L20140708-075-B was 0.000311 mrem.The dose from gas release G20140211-009-C was 0.00335 mrem.Total Dose Calculation 1.14 mrem + 0.000311 mrem + 0.00335 mrem = 1.14 mrem 2014 Annual Radioactive Effluent Release Report for TMI Attachment 9 -Page 1 of I Assessment of Radiation Dose to Most Likely Exposed Real Individual per 40 CFR 190 Dose calculations were performed to demonstrate compliance with 40 CFR 190 (ODCM Part IV Section 2.10). Gaseous and liquid effluents released from TMI-1 and TMI-2 in 2014 resulted in maximum individual doses (regardless of age group) of 0.068 mrem to the thyroid and 0.21 mrem to any other organ including the whole (total) body. The direct radiation component was determined using the highest quarterly fence-line exposure rate as measured by an environmental dosimeter, and subtracting from it, the lowest quarterly environmental dosimeter exposure rate.Based on the maximum exposure rate of 37.4 mR/quarter, a person residing at the fence-line for 67 hours7.75463e-4 days <br />0.0186 hours <br />1.107804e-4 weeks <br />2.54935e-5 months <br /> (shoreline exposure from Reg. Guide 1.109) received an exposure of 1.14 mR.Based on the lowest exposure rate of 16.2 mR/quarter and converting it by the same method yielded a background exposure of 0.49 mR. Therefore, the net exposure from direct radiation from TMINS was 0.65 mR. Combining the direct radiation exposure (assumed to be equal to dose) with the maximum organ doses from liquid and gaseous releases, the maximum potential (total) doses were 0.69 mrem to the thyroid and 0.77 mrem to any other organ.Both doses were well below the limits specified in 40 CFR 190.

2014 Annual Radioactive Effluent Release Report for TMI Attachment 10 -Page 1 of 1 Deviations from the ODCM Sampling and Analysis Regime During 2014 The Turbine Building Integrator (SD-FQ-301) sends a signal to the Turbine Building Compositor (SD-CE-253) to collect a flow proportional sample. In 2012, engineering identified that the integrator does not work at low flows. An Engineering Change Request (ECR) 14-00015 has been completed to upgrade the integrator but determined that industrial cooler blowdown will need to be re-routed.

A second ECR 14-00552 has been completed for this mechanical work.ECR 14-00015 was installed in April 2015, and ECR 14-00552 is scheduled to be installed during 2015. The only known low flow source is from a non-radioactive system -industrial cooler blowdown.

Weekly compensatory sampling to confirm no radioisotopes are present in the industrial coolers will continue until the blowdown is re-routed.

2014 Annual Radioactive Effluent Release Report for TMI Attachment 11 -Page I of 4 Major Changes to Radioactive Waste Treatment Systems The following information is for inclusion in the TMI-1/2 Radiological Effluents Report pursuant to Tech Spec Amendment 284.Licensee initiated safety related changes to the radioactive waste system (liquid, gaseous and solid): 1. Shall be reported to the Commission in the Annual Report for the period in which the evaluation was reviewed.

The discussion of each change shall contain: a. A summary of the evaluation that led to the determination that the change could be made in accordance with 10CFR 50.59;The processing of liquid radwaste materials is unchanged except as noted for the concentrated waste storage capabilities.

The Hittman Building radwaste processing activities remain unchanged whether the waste is transferred from the CWST storage prior to being abandoned, from an RBAT, or directly from an Evaporator.

Below is the summary of conclusion for the Activity's 50.59 Review: Screening Question 1 was answered "Yes" due to the elimination of the design function to store concentrated waste. Storage of concentrated waste is identified as a component function attributed to the CWSTs which have been abandoned in accordance with change document ECR 14-00245.

Questions 2 through 5 have been answered "No" for the Screening.

Therefore, a 50.59 Evaluation was required.The 50.59 Evaluation has all Questions answered "No" so this activity was completed without prior NRC approval.b. Sufficient detailed information to totally support the reason for the change without benefit of additional or supplemental information; The processing of liquid radwaste materials is unchanged except as noted for the concentrated waste storage capabilities.

The Hittman Building radwaste processing activities remain unchanged whether the waste is transferred from the CWST storage prior to being abandoned, from an RBAT, or directly from an Evaporator.

2014 Annual Radioactive Effluent Release Report for TMI Attachment 11 -Page 2 of 4 Below is the problem statement from change document ECR 14-00245: The Miscellaneous Waste Evaporator WDL-Z-1 B concentrates liquid radioactive waste. When waste concentration operations are complete, the Liquid Radioactive Waste (WDL) System was designed to pump the bottoms from the Waste Feed Tank WDL-T-1 3B, i.e., "Bottoms" to its Concentrated Liquid Waste Storage and Forwarding for Disposal (CWDL) Subsystem where it was previously stored and eventually pumped to the waste disposal liners in the Hittman Building.Due to station desire and conditions of the concentrated waste storage tanks, concentrated waste transfer pumps and associated piping, ECR 14-00245 physically abandoned the CWDL Subsystem, i.e., CWSTs, pumps, heat trace, valves, instrument air connections and steam heating.ECR 14-00245 re-established a flow path within the existing piping configuration to allow pumping the Miscellaneous Waste Evaporator Bottoms directly to the waste disposal liner located in the Hittman Building.ECR 14-00245 also established a new flow path with new piping configured to allow pumping the Reclaimed Boric Acid Tanks (RBAT), WDL-T-7A(B), directly to the waste disposal liner located in the Hittman Building.c. A detailed description of the equipment, components and processes involved and the interfaces with other plant systems;The processing of liquid radwaste materials is unchanged except as noted for the concentrated waste storage capabilities.

The Hittman Building radwaste processing activities remain unchanged whether the waste is transferred from the CWST storage prior to being abandoned, from an RBAT, or directly from and Evaporator.

Two isolation valves and a check valve have been added to ensure water inventory cross-contamination does not occur during normal system operations.

This new line enables transport of reclaimed boric acid tank (RBAT) inventory to the Hittman Building when needed. RBAT inventory was previously transferred to the CWSTs enroute to the Hittman Building.

The ultimate destination in the Hittman Building remains unchanged.

2014 Annual Radioactive Effluent Release Report for TMI Attachment 11 -Page 3 of 4 The scope the change included:-Physical abandonment of the CWSTs; Concentrated Radwaste Pumps, WDL-P-1 2A(B); associated valves, piping, instrumentation, heat tracing and Auxiliary Steam System supply for the CWSTs. The abandonment included cutting and capping piping to and from the abandoned portion of the system as necessary.

-Physical abandonment of Instrument Air (IA) tubing/piping and isolation valves to the air operated diaphragm valves mention above.-Re-purpose air-operated diaphragm valves WDL-V-418 and WDL-V-256 to accommodate the transfer of liquid radioactive waste from the Miscellaneous Waste Evaporator Bottoms directly to a waste disposal liner in the Hittman Building.-Installation of a new flow path from the discharge of the Boric Acid Recycle Pumps, WDL-P-13A(B), to a portion of the existing flow path between air-operated valves WDL-V-256 and WDL-V-418.

The new flow path allows transferring of reclaimed boric acid to a liner for disposal as needed.-Removal and installation of heat trace as required.-Changes to the Radioactive Waste Disposal Plant display.d. An evaluation of the change which shows the predicted releases of radioactive materials in liquid and gaseous effluents and/or quantity of solid waste that differ from those previously predicted in the license application and amendments thereto;The processing of liquid radwaste materials is unchanged except as noted for the concentrated waste storage capabilities.

The Hittman Building radwaste processing activities remain unchanged whether the waste is transferred from the CWST storage prior to being abandoned, from an RBAT or directly from an Evaporator.

As stated in the 50.59 Screening Form: GDC 69 "Protection Against Radioactivity Release from Spent Fuel and Waste Storage" is unaffected as the method for processing liquid and radwaste through the Hittman Building is unchanged as evaluated per SE-1 15302-052 "Shipment of Misc.Waste Evaporator Concentrates".

GDC 70 "Control of Releases of Radioactivity to the Environment" continue to be satisfied CWSTs and WDL-P-12A/B pumps abandoned.

2014 Annual Radioactive Effluent Release Report for TMI Attachment 11 -Page 4 of 4 e. An evaluation of the change which shows the expected maximum exposures to individuals in the unrestricted area and to the general population that differ from those previously estimated in the license application and amendments thereto;The processing of liquid radwaste materials is unchanged except as noted for the concentrated waste storage capabilities.

The Hittman Building radwaste processing activities remain unchanged whether the waste is transferred from the CWST storage prior to being abandoned, from an RBAT, or directly from an Evaporator.

Offsite dose projections did not change as a result of this radwaste system modification.

f. A comparison of the predicted releases of radioactive materials, in liquid and gaseous effluents and in solid waste, to the actual releases for the period prior to when the changes are to be made;The processing of liquid radwaste materials is unchanged except as noted for the concentrated waste storage capabilities.

The Hittman Building radwaste processing activities remain unchanged whether the waste is transferred from the CWST storage prior to being abandoned, from an RBAT, or directly from an Evaporator.

No change to predicted releases of radioactive materials, in liquid and gaseous effluents and in solid waste as a result of design change 14-00245.g. An estimate of the exposure to plant operating personnel as a result of the change;and ECR 14-00245 facilitated removal of associated components to reduce radiation and contamination sources remaining in the vicinity, and is intended to reduce long-term personnel dose.h.
