-Prairie Island Nuclear Generating Plant Minnesota Department of Health -Radiation Unit ENCLOSURE 1 OFF-SITE RADIATION DOSE ASSESSMENT January 01, 2007 -December 31, 2007 6 pages follow PRAIRIE ISLAND NUCLEAR GENERATING PLANT OFF-SITE RADIATION DOSE ASSESSMENT FOR January through December 2007 An Assessment of the radiation dose due to releases from Prairie Island Nuclear Generating Plant during 2007 was performed in accordance with the Offsite Dose Calculation Manual as required by Technical Specifications.
Computed doses were well below the 40 CFR Part 190 Standards and 10 CFR Part 50 Appendix I Guidelines.
Off-site dose calculation formulas and meteorological data from the Off-site Dose Calculation Manual were used in making this assessment.
Source terms were obtained from the Annual Radioactive Effluent and Waste Disposal Report prepared for NRC review for the year of 2007.Off-site Doses from Gaseous Release Computed doses due to gaseous releases are reported in Table 1. Critical receptor location and pathways for organ doses are reported in Table 2. Gaseous release doses are a small percentage of Appendix I Guidelines.
Off-site Doses from Liquid Release Computed doses due to liquid releases are reported in Table 1. Critical receptor information is reported in Table 2. Liquid release doses, both whole body and organ, are a small percentage of Appendix I Guidelines.
Doses to Individuals Due to Activities Inside the Site Boundary Occasionally sportsmen enter the Prairie Island site for recreational activities.
These individuals are not expected to spend more than a few hours per year within the site boundary.
Commercial and recreational river traffic exists through this area.For purposes of estimating the dose due to recreational and river water transportation activities within the site boundary, it is assumed that the limiting dose within the site boundary would be received by an individual who spends a total of seven days per year on the river just off-shore from the plant buildings (ESE at 0.2 miles). The gamma dose from noble gas releases and the whole body and organ doses from the inhalation pathway due to Iodine 13 1, Iodine-1 33, tritium and long-lived particulates were calculated for this location and occupancy time. These doses are reported in Table 1.Critical Receptor location and pathways for organ doses are reported in Table 2.
ABNORMAL RELEASES There were a total of two (2) abnormal releases for 2007. The 2007 abnormal releases are summarized below: 1. Leak in Waste Gas System On 10/16/07 during data review, operations noted a negative trend in total volume for the routine Waste Gas System inventory.
Further investigation determined that a Waste Gas Decay Tank Release had not occurred for an atypical length of time. Ventilation monitor trend plots and weekly gas grabs were reviewed and indicated no activity.
It was determined that a very small leak had been present for as much as 6 months. Engineering determined that approximately 3,000 cubic feet of waste gas was lost.Cause: Leakage was identified at the Gas Analyzer Panel pump. The Gas Analyzer was isolated until repairs could be performed.
Leakage stopped. From this location all release would have exited through Unit One Auxiliary Building Ventilation.
Corrective Action: 129 Waste Gas Decay Tank (WGDT), the inservice tank, was sampled for nuclide mix.The identified mix was used in the release calculations but, activity levels were determined to be unrepresentatively low, due to the extended time period of release.Activity levels of the identified mix were extrapolated to the level of the sample taken for a last WGDT release performed prior to the leak: Nuclide Ar-41 Kr-85 Kr-85M Xe-133 Xe-135 TOTAL uCi Released Gamma Dose (mrad)1.08E+02 9.59E+04 7.62E+0 1 2.44E+04 1.32E+03 1.08E-06 2.OOE-04 1.61E-07 2.74E-04 3.48E-06 4.79E-04 Beta Dose (mrad)3.80E-07 1.77E-06 1.00E-07 9.22E-05 2.72E-06 9.72E-05 H3 1.26E+03 uCi 2.16E-06 mrem Activity was applied to abnormal release file RACO 193, as a Unit One Auxiliary Building Release. Release duration was conservatively set at 1 week and total dose was applied to the month of October, the 4 th Quarter.Event was captured in the site's Action Request System: CAP-01 115005.Repairs were accomplished and the Gas Analyzer was returned to service.The dose from the activity released represented a small percentage of the total dose and was a very small percentage of limits. The dose did not impose upon the health and safety of the public.The event was reported to the NRC Region 3 Radiation Protection (RP) Inspector, at the time of the event.Result:
- 2. Leaking 1 .Steam Generator Relief On 6/17/07, while performing a surveillance procedure on I 1 Steam Generator Safety Relief, CV-31084 did not completely reseat. Discharge piping temperatures increased.
The isolation was shut and the valve was stroked in an attempt to reset. It was determined that CV-31084 did reseat as evidenced by decreasing downstream temperatures.
Cause: CV-31084 did not fully reseat during performance of surveillance procedure.
When the valve was unisolated, following performance of the SP, it leaked.Corrective Action: CV-31084 was reisolated and stroked. Leakage ended. Work Request #25903 was issued.Engineering provided a volume released.
Based on this volume it was determined that a one second release with the valve full open would conservatively represent the release volume.The Steam Generators-were sampled and a release file was created to document the release.The dose consequences were determined to be: H3 1.53E+01 uCi 2.6E-09 mrem Activity was applied to abnormal release file RAB0060, as an 11 Steam Generator-Steam Release.Event was captured in the site's Action Request System: CAP-01097198.
Result: The dose from the activity released represented a small percentage of the total dose and was a very small percentage of limits. The dose did not impose upon the health and safety of the public.The event was reported to the NRC Region 3 Radiation Protection (RP) Inspector, at the time of the event.
40CFR190 COMPLIANCE The calculated dose from the release of radioactive materials in liquid or gaseous effluents did not exceed twice the limits of I OCFR50, Appendix I, therefore compliance with 40CFRI190 is not required to be assessed, in this report.SAMPLING.
ANALYSIS AND LLD REQUIREMENTS The minimum sampling frequency, minimum analysis frequency and lower limit of detection (LLD)requirements, as specified in ODCM Tables 2.1 and 3.1 were not exceeded in 2007.MONITORING INSTRUMENTATION There were no occurrences when less than the minimum required radioactive liquid and/or gaseous effluent monitoring instrumentation channels were operable as required by ODCM Tables 2.2 and 3.2.Doses to Individuals Due to Effluent Releases from the Independent, Spent Fuel Storage Facility (ISFSI)Two (2) fuel casks were loaded and placed in the storage facility during the 2007 calendar year. The total number of casks in the ISFSI is twenty-four (24). There has been no release of radioactive effluents from the ISFSJ.CURRENT ODCM REVISION The Offsite Dose Calculation Manual was revised in 2007. The current revision is 21. The revision date is July 25, 2007. A copy is submitted with this year's report.PROCESS CONTROL PROGRAM There were no changes made to the Process Control Program in 2007. Current manual is revision 8, August 25, 1999.

N/A ENCLOSURE 4 ATTATCHMENT TO THE 2007 EFFLUENT REPORT Description and Dose Assessment of Quarter 1 of 2007 Leak Communicated per ODCM (H4, Section 8.4) Industry Initiative on Groundwater Protection 1 page follows ATTACHMENT TO THE 2007 ANNUAL EFFLUENT REPORT 8.4) Industry Initiative on Groundwater Protection Quarter 1, 2007 Summary This dose assessment for the leak described in this attachment did not change the total liquid dose to the critical receptor for the first quarter of 2007.Backgiround On March 21, 2007, approximately 150 gallons of secondary steam condensate leaked to the ground outside the northeast side of the turbine building during transfer of turbine building sump water to the landlocked canal. This water had a tritium concentration of 5,150 pCi/L. The transfer of water was secured and no further leakage to the environment occurred.
This release occurred from a monitored release path.ODCM Considerations Since the release occurred via a monitored release path, the dose calculations were performed per the ODCM. The released effluent did not flow to the normal landlocked location but was absorbed into the ground closer to the turbine building.
At this location, the water has farther to travel to the receptor and is subject to greater dispersion than the normal release location.
The ODCM dose calculations over-estimate the dose from this release. Corrective actions have been taken to prevent a similar spill in the future.Dose Calculation Assumptions The dose calculation was performed per the ODCM for the annual effluent report. This dose over-estimates the dose under the conditions of this release. No revision to the ODCM dose calculation is warranted.
Discussion The critical receptor is located 0.6 miles to the SSE of the Prairie Island site. The leaked water would have to travel in the groundwater under the recycle canal and discharge canal to reach the critical receptor.
This assumed water flow maximizes the dose because the normal groundwater flow is towards the Vermillion River which would not carry the tritium toward the critical receptor.
