Fissien and Activation Gases (Noble Gases) The dose rate due--tci-radioactive materials released-in gaseous effluents from the site to areas at and beyond the-site boundary shall be limited .to less _tlian or equal to 500 mrem/yr to the whole body and less than or equal to 3000 mrem/yr to the skin. The air dose du"* to noble gases released in gasieous effluents, from each unit, to areas at-and beyond the site boundary shall be-limited to the following:

a. During any calendar quarter: Less than or equal to 5 mrad for gamma -radiation-and less than or -equal to 10 mrad for-beta radiation, and b. During any_calendar

_year: Less-than or equal to 10 mrad-for gamma radiation_and less than or equal to 20 mrad for beta radiation.

Iodine-131, Iodine-133, Tritium, Carbon-14, and Y.,a-dioa-ctive-lVIaterial in Particulate Form The dose rate due to iodine-131, iodine-133, tritium, and all radionuclides in particulate form with half lives greater than 8 days, released in gaseous effluents from the site to areas at and beyond the site boundary, shall be limited to less than or equal to 1500 mrem/yr to any organ. The dose to a MEMBER: OF THEPTJBLIC fromiodine-131, iomne-133, tritium, carbon-14, and all radionuclides in-particulate form with half lives greater than 8 days in gaseous effluents released, from -each unit, to areas at and beyond the site boundary, shall be limited to the following:

a. During any calendar quarter: Less than or equal to 7.5 mrem to any organ,and
b. During any calendar_year:

Less than or equal to 15 mrem to any organ. Liquid Effiaents The-=-concentration of radioactive material released in liquid effluents to unrestricted areas-shall be limited to 10 times the concentrations specified in 10 CFR Part 20, Awendix 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 2.0E-4-µCi/ml total activity.

The dose or dose-commitmentto a MEMBER OF THE PUBLIC from radioactive materials in liquid effluents released, from each unit, to unrestricted areas shall be limited: a. During any calendar quarter to less than or equal to 1.5 mRem to the whole body ai"'ld to less than or equal to 5 mrem to any organ, and b. During any calendar year to less than or equal to 3 mRem to the whole body and to less than or equal to 10 mrem to any organ.

Total Dose The annual-( calendar year) dose or dose commitm~nt to any MEMBER OF THE PUBLIC due to-releases of radioactivity and-to raaiation from uranium fuel cycle sources shall be limited to less than or equal to 25 mrem to the whole body or any organ, except the thyroid, which shall limited to less than or eEJ:ual to 75 mrem. -Effluent Concentration Limits Gaseous Effluents For gaseous effluents, effluent concentration-limits (ECL) values are not directly used in release rate calculations since the applicable limits are expressed in tenns sf dose rate at the site boundary.

Liquid Effluents The values specified in 10 CFR Part 20, Apj)endix B, Table 2, Column 2 are used as-the ECLfor liquiciradioactive effluents released to unrestricted areas. A value of2.0E-04-µCi/ml is used as the ECL for dissolved and entrained noble gases in liquid effluents.

Measurements and Approximations of Total RadioacfudJy Measurements of total radioactivity in liquid and gaseous radioactive effluents were accomplished in accordance with the sampling and analysis requirements of Tables 4.11-1 and 4.11-2, respectively, of the St. Lucie ODCM. Estimates of errors are in accordance with Methodology Section 4.0.4, of the ODCM. The estimate of errors associated with values reported are as follows: Error Topic Release Point Mixing Sampling Sample -Preparation Sample Analysis Release Volume Total% LIQUID Avg. %Max.% 2 5 1 5 1 5 3 10 2 5 9 30 (above values are examples only) GASEOUS~ Avg. %Max.% NA NA 2 5 1 5 3 10 4 15 10 35 The-predictability of error for radioactive releases can-only be applied to nuclides that are predominant in sample spectrums.

Nuclides that are near-background relative to the predominant nuclides in a given sample could easily have errors greater than the above listed maximums.

Liquid Radioactive Effluents Each batch release was sampled and analyzed for garnma emitting radionuclides using gamma spectroscopy, prior to release. Cornposite samples were analyzed monthl_y for tritium and gross alpha radioactivity in the onsiteJaboratory using_ liquid scintillation and air ion-chamber _counting techniques, respectively.

Composite samples were analyzed quarterly-for Sr-89, Sr-90, Fe-55, Ni-63 and-C~l4-by a contract laboratory.

The-results of the composite analyses from the-previous month or quarter were used to estimate the -quantities of these radionuclicles in Ii-quid effluents during the current month or quarter. The total radioactivity in liquid effluent releases was dete1mined from-the measured-and estimated-concentrations of each radionuclide present and the total volume ofthe_effluent released during periods of dissharge.

Gaseous Radioactive Effluents Each gaseous bateh~ was sampled__and analyzed for radioactivity prior to -r-elease.

For releases from gas-decay tanks~_noble gas grab samples-Were analyzed for gamma emitting radionuclides usii~g gamma spectroscopy.

For releases from the reactor containment buildings, samples were taken of noble gas and tritium grab samples and analyzed for gamma emitting radionuclides prior to each release. The results of the analyses and the total volume of effluent released were used to determine the total amount of radioactivity released in the batch mode. For continuous effluent release pathways, noble gas and tritium grab samples were collected and analyzed weekly for gamma emitting radionuclides by gamrna-spectrescopy and liquid scintillation counting techniques, respectively.

Continuous release pathways were continuously sampled using radioiodine adsorbers and particulate filters. The radioiodine adsorbers and particulate filters were analyzed weekly fer gamma emitting radionuclides using gamma spectroscopy.

Results of the noble gas and tritiu.m.

grab samples, radi-oiodine adsorber and particulate filter analyses from the current week and the average effluent flow rate for the previous week were used to determine the total amount of radioactivity rel-eased in the continuous-mode.

The particulate filters were analyzed weekl-y for_gross alpha activity in-the onsite laboratory using the air ion chamber-counting technique.

Quarterly composites of particulate filters were analyzed for Sr-89 and Sr-90 by a contract laboratory.

Meteor.olo_gical Monitoring Program In accordance with ODCM Ad.ministJ;ative Control 3.11.2.6.b., a summary of hourly meteorological data, collected during 2017, is retained onsite. This data is available for review by the NRC upon request. During 2017, the goal of>90% joint data recovery was met. Actual meteorological data collected during the year was used for the offsite dose calculations in this report.

.Carbon-14 Dose Estimation The estimate of Carbon-14 (C-14) released from the St.Lucie Nuclear Plant was derived frnm the EPRI. document, "Estimation of Carbon-14 in Nuclear-Power Plant Gaseous Effluents", Report 1021106, issued December 20-10. The site specific source term values used in the St. Lucie calculations were taken frnm the PWR Section, Page 4-28 of the report, and employed the proxy generation rate values for a Combustion Enw.u.11eering reactor:-The actual 2017 operating data for-the units was employed for the calculations to derive the total curies released for each unit. The total amount of C-14 .released in 2017 for Unit 1 was 11.24 Ci, and the total amount of C-14 released in 2-017 frn.c Unit 2 was 10.32 Ci. The highest_calculated dose exposure pathway from C-14 is "Bone Dose" to a "Child" from consumption of garden prodnce. A "Child" consuming vegetables and produce--from the garden located at 2-.ff miles in the West direction from the :R_lant would havITTeceived a total combine_d___"Bone Dose", from C-14, of l.63e-1 mrem/yr. Assessment ofradiation dose from radioactive effluents to members of the public due to their activities inside the site boundary assumes the visitor to be a lifeguard at Walton Rocks Beach Recreation Area located 1 mile southeast of the site. Dose to the visitor on site for calendar year 2017 is found to be 2.80E-03 mrem/yr, Total-Body dose._See Table 3.4, Dose Assessments, for more-detail.

This is a fraction of the 1 mrem annuafwhole body-dose received by the -average US citizen from natural occurring Carbon-14, primarily generated through cosm-ogenesis-in the terrestrial biosphere. (Reference National Council of Radiation Protection Report 45, Natural Background Radiation in-the United States.) All C-14 dose calculations are based-on Regulatory Guide 1.109 values.

2.0 SUPPLEMENTAL INFORMATION 2.1 Abnormal Releases or Abnormal Discharges 2A GDT Unplanned Release -(AR# 02193168 I WR#94157276)

  • One abnormal (unplanned) gas decay tank discharge from the site occurred on March 22, 2017. Operations entered 2-AOP-06.04, Uncontrolled Release of Radioactive Gas, due to loss of31 psig in a 12 hour1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> period from the 2A Gas Decay Tank (GDT). The 2A GDT Unplanned Release was accounted for using a Abnormal , Gas Decay Release Permit, G-17-119-B.

AR #02193168 was generated to, document the unplanned GDT release to the auxiliary building which was monitored by an operable plant vent radiation monitor on the plant vent stack. No additional leaks have been identified since its return to service. Release Estimates Are As Follows: Nuclide uCi/cc concentration uCi released Kr-85 2.940E-04 3.890E+03 Xe-131m 2.240E-05 2.964E+02 Xe-133 2.820E-04 3.731E+03 Maximum Infant Dose for NW Site Boundary:

Total Body Skin Gamma Air Beta Air (mRem) (mRem) (mRad) (mRad) 6.021E-08 4.094E-07 7.25E-08 6.00E-07.

2.2 Non-Routine Planned Discharges No non-routine planned discharges were made during the report period. 2.3 Radioactive Waste Treatment System Changes No changes were made to the radioactive waste treatment system during the report period. 2.4 Annual Land Use Census Changes No changes were made to the Land Use Census during the report period as compared to the previous year's report.

2.5 Effluent Monitoring System Inoperability One effluent monitor was out of service for greater than 30 days during the report period. On January 18t\ 2018 I&C Maintenance was performing the ECCS radiation monitors monthly functional surveillance in accordance with 1-SMI-26.03.

At this time it was identified that the 'B' ECCS radiation monitors alarm leads were lifted (i.e. de-termed).

The discrepancy was corrected and RSC-26-3 returned to service on January 19th, 2018. During the Past Operability/Functionality Review it was determined that the leads were lifted under WO: 40400949-16, to support installation of the A ECCS radiation monitor. With the B ECCS alarm leads lifted the radiation monitor should have been declared inoperable and St. Lucie could have either restored the radiation monitor within 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> or initiated and alternate method of monitoring.

St Lucie Unit 1 did not perform the applicable action statement as required by the Offsite Dose Calculation Manual. With the Alarm leads lifted the B ECCS radiation monitor would have performed its required function locally at the ECCS monitor. This means the radiation monitor would have monitored radiation levels using the normal and accident monitors depending on the radiological conditions.

In addition, the radiation monitors local display would have indicated and alarmed to alert plant personnel of abnormal radiation conditions or a monitor failure. If a failure of the radiation monitor had occurred it would have not annunciated in the control room, thus not meeting the requirement of ADM-11.16 guidance.

During the timeframe that this channel of alarm capability was defeated, the remote monitoring displays of actual values to the control room and other monitoring areas remained functional.

Upon review, no effluent releases were performed through this effluent pathway. All gaseous releases during the time frame of December 15th, 2017 and January 18th, 2018, were planned and monitored via approved release pathways.

2.6 Offsite Dose Calculation Manual Changes Three revision changes were made to the St. Lucie Site ODCM during the report period.

  • Revision 50 -Incorporated PCR 2223046 to remove affected process effluent radiation monitors from the Technical Specifications and incorporate them into the Offsite Dose Calculation Manual. (Author: T. Bertolini)
  • Revision 49 -Incorporated PCR 2137189 per EC 278372 to update values in Methodology Section. (Author: T. Bertolini)
  • Revision 48 -Incorporated PCR 2184 721 to add note to cover page ensuring that changes to the ODCM are reviewed by EP. (Author: N. Davidson)
2. 7 Process Control Program Changes There were no changes to the Process Control Program during the report period. 2.8 Corrections to Previous Reports There were no corrections to previous reports during the report period. 2.9 Other Five batch releases were made from the South Settling Basin to the Intake Canal during the report period to lower the water level from periods of higher than normal rainfall.

All releases were analyzed according to the ODCM and site procedural requirements and were found to have no detectable gamma, tritium, alpha or hard to detect isotopes.

The releases are listed below: Release Start Date 7/30/17 9/6/17 9/13/17 10/4/17 10/28/17 Release Volume 447,662 gallons 19,908,299 gallons 904,523 gallons 4,337,515 gallons 3,790,000 gallons 2.10 Groundwater Protection Program
