SUBJECT:
TURKEY POINT NUCLEAR PLANT - INTEGRATED INSPECTION REPORT 05000250/2004002 AND 05000251/2004002
Dear Mr. Stall:
On March 27, 2004, the US Nuclear Regulatory Commission (NRC) completed an inspection at your Turkey Point Units 3 and 4. The enclosed integrated inspection report documents the inspection findings which were discussed on April 6, 2004, with Mr. M. Pearce and other members of your staff.
The inspection examined activities conducted under your license as they relate to safety and compliance with the Commissions rules and regulations and with the conditions of your license.
The inspectors reviewed selected procedures and records, observed activities, and interviewed personnel.
Based on the results of this inspection, the inspectors identified three findings of very low safety significance (Green). The findings were determined to involve violations of NRC requirements.
However, because of the very low safety significance and because the violations were entered into your corrective action program, the NRC is treating the violations as non-cited violations (NCV) in accordance with Section VI.A of the NRCs Enforcement Policy. Additionally, a licensee-identified violation which was determined to be of very low safety significance is listed in Section 4OA7 of this report. If you contest the NCV in this report, you should provide a response, within 30 days of the date of this inspection report, with the basis for your denial, to the Nuclear Regulatory Commission, ATTN: Document Control Desk, Washington, DC 20555-0001; with copies to the Regional Administrator, Region II; the Director, Office of Enforcement, United States Nuclear Regulatory Commission, Washington, DC 20555-0001; and the NRC Senior Resident Inspector at the Turkey Point facility.
In accordance with 10 CFR 2.390 of the NRC's "Rules of Practice," a copy of this letter and its enclosure will be available electronically for public inspection in the NRC Public Document Room or from the Publicly Available Records (PARS) component of NRC's
FPL 2 document system (ADAMS). ADAMS is accessible from the NRC Web site at http://www.nrc.gov/reading-rm/adams.html (the Public Electronic Reading Room).

SUMMARY OF FINDINGS
IR 05000250/2004-002, 05000251/2004-002; 12/28/2003 - 03/27/2004; Turkey Point Nuclear
Power Plant, Units 3 and 4; Radioactive Gaseous and Liquid Effluent Treatment and Monitoring Systems; Event Followup The report covered a three month period of inspection by resident inspectors and announced inspections by two region based operations engineers, four region based health physicists, one region based emergency preparedness inspector, and one region based engineering specialist inspector. Three Green non-cited violations (NCV) were identified. The significance of most findings is identified by their color (Green, White, Yellow, Red) using IC 0609, Significance Determination Process (SDP). Findings for which the SDP does not apply may be Green or be assigned a severity level after NRC management review. The NRCs program for overseeing the safe operation of commercial nuclear power reactors is described in NUREG-1649,
Reactor Overnight Process, Revision 3, dated July 2000.
NRC Identified
& Self-Revealing Finding
Cornerstone: Public Radiation Safety
- Green.
The inspectors identified a non-cited violation (NCV) of Technical Specification (TS) 6.8.1.d for failure to correctly calibrate selected effluent monitoring instrumentation in accordance with Offsite Dose Calculation Manual (ODCM)specifications. Specifically, the licensee failed to use National Institute of Standards and Technology (NIST) traceable secondary sources related to the initial monitor calibrations during the most recent calibrations of the gas decay tank noble gas effluent monitor (R-14), the liquid radioactive waste effluent monitor (R-18), the Unit 3 (U3) and Unit 4 (U4) Steam Jet Air Ejector monitors (R-3/4-15), and the U3 and U4 Steam Generator Blow-Down monitors (R-3/4-19).
This finding is greater than minor because it adversely affects the effluent monitoring equipment attribute of the Public Radiation Safety cornerstone in that failure to use NIST traceable secondary sources could impair the accuracy of effluent monitoring equipment required to ensure adequate protection of public health and safety from exposure to radioactive materials released into the public domain as a result of routine civilian nuclear reactor operations. The finding is of very low safety significance because there was no failure to assess dose to the public and doses did not exceed Appendix I to10 CFR Part 50 design criteria. (Section 2PS1)
- Green.
The inspectors identified a non-cited violation of TS 6.8.1.e for failure to implement Quality Control activities for the conduct of representative sampling and monitoring of particulates in the main plant vent airborne effluents. Specifically, the main plant vent airflow flow characteristics were outside of the design specified exhaust flowrate and resultant velocities necessary to maintain isokinetic sampling of particulates by the main plant vent Sample Particulate Iodine, and Noble Gas (SPING) monitoring and sampling equipment (RAD 6304).
This finding is greater than minor because it adversely affects the effluent monitoring program and process attribute of the Public Radiation Safety cornerstone in that failure to maintain isokinetic sampling could impact representative sampling and subsequent monitoring of particulates in airborne effluents released into the public domain as a result of routine civilian nuclear reactor operations. The finding is of very low safety significance because there was no failure to assess dose to the public from airborne particulates released from the main plant vent and doses did not exceed Appendix I to10 CFR Part 50 design criteria. (Section 2PS1)
Cornerstone: Mitigating Systems
- Green.
A self revealing non-cited violation of Technical Specification 3.1.2.3 was identified for failure to maintain at least two charging pumps operable. This condition occurred when Isolation Valve 3-280H for the 3C Charging Pump interlock pressure control switch PS-3-201C was mispositioned closed.
The finding was greater than minor because it involved the equipment performance attribute of the mitigating system cornerstone and affected the objective of ensuring that equipment is available and capable to respond to an event. The finding was determined to be of very low safety significance in accordance with the Significance Determination Process (SDP) phase 2, since one charging pump remained operable and available to perform the safety function. (Section 4OA3)
B. Licensee Identified Violation A violation of very low safety significance, which was identified by the licensee, has been reviewed by the inspectors. Corrective actions taken or planned by the licensee have been entered into the licensees corrective action program. The violation and corrective action tracking number are listed in Section 4OA7 of this report.

1EP5 Correction of Emergency Preparedness Weaknesses and Deficiencies
a. Inspection Scope
The inspectors evaluated the efficacy of licensee programs that addressed weaknesses and deficiencies in emergency preparedness. The procedure governing the plant corrective action program was reviewed for applicability to the emergency preparedness program. Since the last inspection of this program area (February 2002), no emergency declarations were made by the licensee. Audits performed in accordance with 10 CFR 50.54(t) and a self-assessment were reviewed. The inspectors evaluated selected drill scenarios and associated critiques to determine whether the licensee had properly identified failures to implement regulatory requirements and planning standards. A sample of weaknesses and deficiencies identified by means of these licensee processes was evaluated to determine whether corrective actions were effective and timely.
Licensee procedures, records, and other documents reviewed within this inspection area are listed in the Attachment to this report.
Findings No findings of significance were identified.
1EP6 Drill Evaluation
a. Inspection Scope
On February 24, 2004, the inspectors monitored the participation of emergency response organization (ERO) personnel in the Technical Support Center (TSC) during the first quarter emergency preparedness (EP) drill of the site emergency plan. During the drill the inspectors assessed if actions taken for emergency classification, notification, and protective action recommendations were made in accordance with the EP implementing procedures and 10 CFR 50.72. Specifically, the inspectors reviewed whether the initial activation of the emergency response centers was correctly conducted due to a steam generator tube rupture and loss of offsite power. Technical specifications required actions during the drill were reviewed to assess correct implementation. Drill critique items were discussed and reviewed with the licensee to verify that drill issues were being identified and captured. Additionally, on March 5, 2004, the inspectors verified that Alert sirens used during Emergency Evacuations were working and that pre and post test messages were clearly audible and stated in both English and Spanish, at two remote siren site locations during the 1st Quarter Miami-Dade County Alert siren test.
b. Findings
No findings of significance were identified.
RADIATION SAFETY
Cornerstones: Occupational Radiation Safety and Public Radiation Safety 2OS3 Radiation Monitoring Instrumentation
a. Inspection Scope
Area Radiation Monitoring Systems The operability, availability, and reliability of selected direct area radiation monitoring and continuous air monitoring equipment used for routine and accident monitoring activities were reviewed and evaluated. The inspectors reviewed Area Radiation Monitor (ARM) system details specified in Updated Final Safety Analysis Report (UFSAR) Section 11.2 and subsequently reviewed and discussed with cognizant licensee representatives the most recent periodic System Engineer System Health reports for ARMs including the Containment High Range Area Radiation Monitor (CHRM) and Post Accident Sampling System equipment. In addition, calibration and repair records for selected ARM equipment were reviewed and discussed with licensee representatives. During the week of February 23, 2004, the inspectors directly observed equipment material condition, installed configurations (where accessible), and local and control room readouts; and reviewed established alarm set-points for selected Unit 3 (U3) and Unit 4 (U4) CHRM and Spent Fuel Pool (SFP) ARM equipment.
Program guidance, performance activities, and equipment material condition for the direct radiation detection instrumentation and continuous air sampling equipment were reviewed against details documented in Technical Specification (TS) 6.8.1, 10 CFR Parts 20 and 50, UFSAR Section 11, applicable Design Basis Document (DBD) details, and associated procedures.

Operability and analysis capabilities of the whole body counting (WBC) equipment for monitoring internally deposited radionuclides and Personnel Contamination Monitor (PCM) equipment utilized for surveys of individuals exiting the Radiologically Controlled Area (RCA) were evaluated. For both WBC and PCM equipment, current calibration and recent operational/performance test surveillance data, as applicable, were evaluated. The licensees radionuclide data base library used for routine WBC analyses was reviewed against current dry active waste (DAW) 10 CFR Part 61 analyses and discussed with licensee representatives. Selected WBC data analyses were reviewed and discussed with responsible staff to assess knowledge and proficiency in equipment operation and in evaluating WBC results for measurable intakes which could result in committed effective dose equivalent (CEDE) values assigned to occupational workers.
Licensee activities associated with personnel radiation monitoring instrumentation were reviewed against TS 6.8.1; 10 CFR 20.1204 and 20.1501; and applicable licensee procedures listed in Section 2OS3 of the report Attachment.
Protective Equipment Respiratory Protection - Self Contained Breathing Apparatus (SCBA) The licensees respiratory protection program guidance and its implementation for use of Self Contained Breathing Apparatus (SCBA) equipment was evaluated. The inspectors reviewed records associated with supplied air quality and maintenance activities for SCBA equipment. The number of available staged SCBA units, and their general material condition and bottle air pressure were observed during tours of the Control Room, RCA control point, and Operational Support Center (OSC) storage locations. During the week of February 23, 2004, the inspectors reviewed and evaluated records associated with current medical qualification determinations, fit test results, and training status for selected emergency response personnel assigned duties requiring use of SCBA equipment. In addition, selected operators were interviewed to determine their level of knowledge of SCBA equipment locations, and proper use.
Licensee activities associated with maintenance and use of SCBA equipment were reviewed against TS, 10 CFR Part 20.1703, UFSAR Section 11, Emergency Plan details, American Nuclear Standards Institute (ANSI)-Z88.2-1992, American National Standard Practices for Respiratory Protection, and applicable procedures listed in Section 2OS3 of the report Attachment.

b. Findings
No findings of significance were identified.
2PS1 Radioactive Gaseous and Liquid Effluent Treatment and Monitoring Systems
a. Inspection Scope
Effluent Processing Equipment. During the week of February 23, 2004, the inspectors reviewed and evaluated the operability, availability, and reliability of selected radioactive effluent process sampling and detection equipment used for routine and accident monitoring activities. Inspection activities consisted of direct observation of installed equipment configuration and operation, and review of calibration and performance data for the liquid and gaseous effluent process systems.
The inspectors directly evaluated selected U3 and U4 effluent process monitoring equipment for material condition and assessed selected processing and monitoring components against design configuration and operating specifications. During walk-downs, accessible sections of the liquid waste system including waste monitor tanks, system piping, and the liquid radioactive waste (radwaste) effluent line radiation monitor (R-18) were assessed for material condition and conformance with current system design diagrams. Inspected components of the main gaseous effluent process and release system included the waste gas decay tanks; radiation monitoring instrumentation for the gas decay tank noble gas monitor (R-14); and the U3 and U4 condenser Steam Jet Air Ejector (SJAE) noble gas (R-3/4-15) and Sample Particulate Iodine Noble Gas (SPING)[RAD-3/4-6417] monitoring equipment. For the main plant vent SPING (RA-6304), the inspectors evaluated sample lines interior to the plant. The inspectors interviewed chemistry supervision regarding liquid and gaseous radwaste system configurations, system modifications, and effluent monitor operation. The inspectors compared U3/U4 plant vent flow rates and velocities to the Rad-6304 sample line flow rates and resultant velocities to evaluate equipment operation for isokinetic sampling conditions. In addition, the most recent surveillances test results for the emergency containment filter and control room emergency ventilation systems were reviewed and discussed with licensee representatives.
The inspectors reviewed applicable sections of licensee effluent monitor calibration procedures and evaluated results of calibration and/or functional tests for the liquid radioactive waste (radwaste) monitor (R-18), gas decay tank noble gas monitor (R-14),and the main plant vent SPING equipment (RAD-6304), and the U3 and U4 condenser SJAE noble gas monitors (R-3/4-15). The reviewed data included isotopic calibration records, source check results, and flowmeter calibration records. The inspectors also reviewed out-of-service data and selected contingency sampling records for effluent monitors from January 1, 2003 through January 31, 2004.
Installed configuration, material condition, operability, and reliability for selected effluent sampling and monitoring equipment were reviewed against 10 CFR Parts 20 and 50; Regulatory Guide (RG) 1.33, Quality Assurance Program Requirements (Operation),
February 1978; RG 1.21, Measuring, Evaluating and Reporting Radioactivity in Solid Wastes and Releases of Radioactive Materials in Liquid and Gaseous Effluents from Light-Water Cooled Nuclear Power Plant, June 1974; ANSI-N13.1-1969, Guide to Sampling Airborne Radioactive Materials in Nuclear Facilities; ANSI-N13.10-1974, ANS Specification and Performance of On-Site Instrumentation for Continuously Monitoring Radioactivity in Effluents; TS Section 6.8 1; the Offsite Dose Calculation Manual (ODCM), Rev. 11; and UFSAR Chapter 11. Procedures and records reviewed during the inspection are listed in Section 2PS1 of the report Attachment.
Effluent Release Processing and Quality Control Activities. The inspectors evaluated licensee performance in conducting effluent release processing and quality control (QC)activities including implementation of program guidance and chemistry and operations staff proficiency. The inspection consisted of direct observation of sampling and release operations, examination of count room equipment and daily QC activities, and review of effluent release procedural guidance and documentation.
The inspectors directly observed the weekly collection of airborne effluent samples from the U3 SJAE SPING (Rad -3-6417) as part of a continuous gaseous release. The collection of a tritium sample from the U4 containment purge exhaust was also observed. The inspectors evaluated chemistry technician proficiency in collecting, processing, and counting the samples. In addition, the inspectors interviewed and observed operations personnel during conduct of a February 26, 2004, A Waste Monitor Tank liquid effluent release.
QC activities regarding gamma spectroscopy and liquid scintillation counting instrumentation were discussed with a count room technician and Chemistry supervision. The inspectors reviewed calibration records and daily QC check trends, observed daily QC check performance, and evaluated the data against procedural guidance for germanium detector numbers 1, 2, and 3 and the Packard liquid scintillation counting equipment. In addition, quarterly radiochemistry cross-check program results from the first quarter of 2002 through the second quarter of 2003 were reviewed and discussed with cognizant licensee representatives.
Procedures for effluent sampling, processing, and release were evaluated for consistency with licensee actions. Three liquid and four gaseous release permits were reviewed against current procedural guidance and ODCM specifications. The ODCM was reviewed to determine whether any changes were made since January 1, 2001.
The inspectors also reviewed the Calendar Year (CY) 2001 and CY 2002 annual effluent reports for effluent release data trends and anomalous releases.
Observed task evolutions, count room activities, and offsite dose results were evaluated against details and guidance documented in the following: 10 CFR Parts 20 and Appendix I to 10 CFR Part 50; ODCM; RG 1.21, Measuring, Evaluating and Reporting Radioactivity in Solid Wastes and Releases of Radioactive Materials in Liquid and Gaseous Effluents from Light-Water Cooled Nuclear Power Plant, June 1974; RG 4.15, Quality Assurance for Radiological Monitoring Programs (Normal Operation) - Effluent Streams and the Environment, December 1977; RG 1.109, Calculation of Annual Doses to Man from Routine Releases of Reactor Effluents for the Purpose of Evaluating Compliance with 10 CFR Part 50 Appendix I, October 1977; ANSI-N13.1-1969, Guide to Sampling Airborne Radioactive Materials in Nuclear Facilities; and ANSI-N13.10-1974, ANS Specification and Performance of On-Site Instrumentation for Continuously Monitoring Radioactivity in Effluents. Procedures and records reviewed during the inspection are listed in Section 2PS1 of the report Attachment.
Problem Identification and Resolution. Five licensee corrective action documents and an audit associated with effluent release activities were reviewed and assessed. The inspectors assessed the licensees ability to identify, characterize, prioritize, and resolve the identified issues in accordance with licensee procedure NAP-400, Condition Reports, Rev. 0. Reviewed guidance documents and data are listed in Section 2PS1 of the report Attachment.
b. Findings
.1 Failure to Implement ODCM Requirements
Introduction.
A Green NRC-identified Non-Cited Violation (NCV) for the failure to implement ODCM calibration requirements for selected effluent monitors was identified.
Description.
During a review and discussions of effluent monitor calibration procedures and records, the inspectors determined that the licensee did not use secondary calibration sources while calibrating selected effluent monitors. A secondary calibration source is a calibration source whose effects on the system were established at the time of the primary calibration and, therefore, has a known relationship to the primary calibration. Specifically, the licensee did not use National Institute of Standards and Technology (NIST) traceable secondary calibration sources during calibrations of the gas decay tank noble gas monitor (R-14), the liquid radwaste effluent monitor (R-18),the U3 and U4 condenser Steam Jet Air Ejector (SJAE) noble gas monitors (R-3/4-15),and the U3 and U4 Steam Generator Blow-Down (SGBD) monitors (R-3/4-19). For some of the data reviewed, the inspectors noted that check sources were used during portions of the electronic calibrations; however, the resultant count rates produced were not linked to the count rates measured during the primary calibrations.
Analysis.
The inspectors determined that the licensees failure to correctly calibrate the process effluent monitors was a performance deficiency. The finding is more than minor because it was associated with the Public Radiation Safety Cornerstone plant equipment/process radiation monitoring attribute and affected the associated cornerstone objective to ensure adequate protection of public health and safety from exposure to radioactive materials released into the public domain as a result of routine civilian nuclear reactor operations. The finding impaired the licensees ability to assess dose; however, for each of the affected effluent pathways, the finding did not result in the licensees failure to assess dose and doses did not exceed Appendix I to 10 CFR Part 50 values. For monitors R-14 and 18, the licensee performed sampling and analysis before each liquid or gaseous effluent batch release. For monitors R3/4-15 and R3/4-19, other properly calibrated SPING effluent monitoring equipment/systems were operational and provided monitoring for each of the affected effluent pathways.
Enforcement.
TS 6.8.1.d requires written procedures to be established, implemented, and maintained covering ODCM implementation. Offsite Dose Calculation Manual Surveillance Requirements 2.1.1 and 3.1.1 require, respectively, that each radioactive liquid and gaseous effluent monitoring instrumentation channel be demonstrated operable by performance of the channel check, source check, channel calibration and analog channel operational test at the frequencies shown in Table 2.1-2 and Table 3.1-2. Table 2.1-2 and Table 3.1-2, respectively, require the monitor on the liquid effluent line and monitors on the gas decay tank, condenser air ejector vent, plant vent, and spent fuel pit building vent systems be calibrated at least once per 18 months.
Table 2.1-2, Notation 2 and Table 3.1-2, Notation 3, require initial channel calibrations be performed using one or more of the reference standards certified by NIST or using standards that have been obtained from suppliers that participate in measurement assurance activities with NIST. For subsequent channel calibration, sources that have been related to the initial calibration shall be used.
Contrary to TS 6.8.1.d, current calibrations for selected effluent monitors were not conducted using NIST traceable secondary sources that were related to the initial calibration as specified in the ODCM. Because the failure to correctly calibrate effluent monitors was determined to be of very low safety significance and has been entered into the licensees corrective action program (CR No. 04-0934), this violation is being treated as an NCV, consistent with Section VI.A.1 of the NRC Enforcement Policy:
NCV 05000250, 251/2004002-01, Failure to Correctly Calibrate Selected Effluent Monitoring Instrumentation in Accordance With ODCM Requirements.
.2 Failure to Implement Quality Control Requirements
Introduction.
A Green NRC-identified NCV of TS 6.8.1.e was identified for failure to implement Quality Control (QC) activities for the conduct of representative sampling and monitoring of particulates in the main plant vent airborne effluents.
Description.
During a review of design and current operating flow-rate characteristics for the main plant vent, the inspectors noted current exhaust flow rates, averaging approximately 77,000 cubic feet per minute (cfm), were outside of documented design/operating limits of 130,000 cfm + 20 percent (%) required for proper isokinetic sampling of airborne effluent particulates. Further, review of main stack flow-rate data demonstrated that the current observed flow-rate was indicative of long-term routine operations. From discussions with cognizant licensee representatives and review of Licensee Design Package Document, RAD-6304 Plant Vent Stack Sample Nozzle Modification and Relocation, dated July 12, 1982, and Plant Change Modification (PCM)82-147 specifications, the inspectors noted that the current plant vent nozzle was installed and sized to provide isokinetic sampling at a plant vent stack flow-rate of 130,000 cfm + 20 %. The documented specifications further detailed that the vacuum pump for main plant vent sample line supplying the SPING equipment (Rad-6304)should be operated at a flow-rate of 60 liters per minute (lpm) to provide isokinetic sampling for a plant vent stack flow-rate of 130,000 cfm + 20 %. From discussions with licensee representatives, the inspectors determined that the flow-rate in the sample line supplying the Rad-6304 SPING equipment was procedurally maintained as specified, i.e., flow-rate of approximately 60 lpm. However, no similar program or process controls were identified that maintained the main plant vent flow-rate within the design specifications.
Analysis.
The inspectors determined that the licensees failure to operate the plant vent flow rates and resultant velocities within established design/operating specifications was a performance deficiency. This finding is associated with the Public Radiation Safety Cornerstone and adversely affects the cornerstone objective attribute of having adequate programs and processes for accurate measurement of offsite dose and is, therefore, more than minor. This finding was evaluated using the Public Radiation Significance Determination Process (SDP). It is of very low safety significance based on current plant operations and processing of plant vent effluents which result in small diameter particulates which are not readily affected by the observed anisokinetic conditions. The finding did not result in the licensees failure to assess dose and doses did not exceed Appendix I to 10 CFR Part 50 values.
Enforcement.
TS 6.8.1.e requires written procedures to be established, implemented, and maintained covering the QC Program for effluent monitoring using the guidance in RG 1.21, Rev. 1, June, 1974. Footnote 1 of RG 1.21 references ANSI N.13.1-1969 as an acceptable standard which includes general principles and guidance for representative sampling of particulates in airborne effluent streams. The standard specifies, in part, that non-representative sampling can result when velocities are anisokinetic.
Contrary to TS 6.8.1.e, the inspectors determined no QC programs or processes were established to maintain representative sampling of particulates in the main plant vent airborne effluents. Because the failure to maintain and implement the established design and operating criteria for the main plant vent airborne effluents and sampling system was determined to be of very low safety significance and has been entered into the licensees corrective action program (CR No. 04-0944) this violation is being treated as an NCV, consistent with Section VI.A.1 of the NRC Enforcement Policy:
NCV 05000250, 251/2004002-02, Failure to Maintain QC Program Activities for the Conduct of Representative Sampling and Monitoring of Particulates In the Main Plant Vent Airborne Effluents.
2PS3 Radiological Environmental Monitoring Program (REMP) and Radioactive Material Control Program
a. Inspection Scope
REMP Implementation. The licensees Annual Radiological Environmental Operating Reports for Calendar Year (CY) 2001 and CY 2002 were reviewed and discussed with cognizant licensee representatives. The inspectors discussed and evaluated the reported data for trends in radionuclide concentrations, anomalous/missing data, and land-use census information. Quality control (QC) activities and data for selected sample types listed in the reports were reviewed and evaluated including inter-laboratory comparison results; analytical assumptions used in gross beta analyses; calculations for surface water cobalt-60, manganese-54, and gross beta lower limit of detection (LLD)determinations; and CY 2003 semiannual sample pump air flow calibration data.
Equipment operational status and staff proficiency for implementing REMP activities were assessed through review of records, observations of equipment material condition and operating characteristics, and through assessment of selected sample collection activities. Collection of weekly air particulate filters/charcoal cartridges and air flow rate determinations were observed at sampling station location numbers (nos.) T-52, T-58, T-72, and a supplemental station located at the day care center. Collection of surface water and vegetation samples at sampling station nos. T-84 and T-41, respectively, were observed and discussed. During observations of sample collection, the inspectors evaluated the proficiency of staff collecting the samples, and assessed the adequacy and implementation of selected collection techniques. The placement and material condition of thermoluminescent dosimetry (TLD) equipment were assessed at sample station location nos. NW-1, NW-5, W-5, WNW-10, W-9, WSW-8, W-8, SW-8, SSW-10.
Using Global Positioning System equipment, the inspectors independently assessed selected TLD and air sampling locations and compared the current location data to Off Site Dose Calculation Manual (ODCM) specified locations.
REMP guidance, implementation, and results were reviewed against ODCM, Rev. 11 guidance and applicable procedures listed in section 2PS3 of the report Attachment.
Meteorological Monitoring Program. Licensee program activities to assure accuracy and availability of meteorological monitoring data were evaluated through review of calibration and surveillance data and direct observation of equipment and data readouts at the primary tower, backup tower, and control room. Current calibration data were reviewed and equipment performance, reliability, and conduct of routine surveillances were discussed with operations and vendor technician staff responsible for tower equipment maintenance and surveillances. Meteorological data availability were reviewed and discussed with licensee representatives for the period CY 2001 through CY 2003. The inspectors observed performance of the weekly meteorological tower system inspections and daily control room surveillances. The inspectors also verified consistency between meteorological tower local readouts and control room data.
Meteorological instrument operation, calibration, and maintenance were reviewed against details listed in the UFSAR, Chapter 2; NRC Safety Guide 23, Onsite Meteorological Programs-1972; ANSI -3.11-2000, Determining Meteorological Information; Regulatory Guide (RG) 1.21, Measuring, Evaluating and Reporting Radioactivity in Solid Wastes and Releases of Radioactive Materials In Liquid and Gaseous Effluents from Light-Water Cooled Nuclear Power Plant, June 1974; and RG 4.15, Quality Assurance for Radiological Monitoring Programs (Normal Operation) -

.
Unrestricted Release of Materials from the Radiologically Controlled Area (RCA).
Radiation protection program activities associated with the unconditional release of potentially contaminated materials or personnel from dress-out facilities and RCA egress points were evaluated. The evaluation included review of calibration records associated with personnel contamination monitor (PCM), portal monitor (PM), and Small Article Monitor (SAM) equipment located at the Dress-Out Building, RCA exit portal, and the Main Truck gate. The inspectors also observed source checking of two personnel contamination monitors, two portal monitors, and two material survey monitors. Source activity and radionuclides used for checks and equipment minimum detectable activities were discussed with an instrument technician. In addition, a low level source, approximately 5000 disintegration per minute, was used to evaluate monitor sensitivity for selected PM and PCM equipment.
The inspectors verified that radiation detection sensitivities were consistent with NRC guidance in IE Circular 81-07 Control of Radioactively Contaminated Material, May 14, 1981, and IE Information Notice 85-92, Surveys of Wastes Before Disposal from Nuclear Reactor Facilities. Documents reviewed are listed in section 2PS3 of the report

4OA3 Event Followup
.1 (Closed) Licensee Event Report (LER) 05000250/2003010-00, Operation With Two
Charging Pumps Inoperable In Excess of Technical Specifications Allowable Limits
a. Inspection Scope
The inspectors reviewed the LER and associated Condition Report 03-2349, which documented this event in the corrective action program, to verify that the cause of the August 29, 2003, failure of the 3C Charging Pump, was identified and that the corrective actions were reasonable. On August 29, 2003, the 3C Charging pump failed to start due to a mispositioned valve. The 3C Charging Pump oil pressure sensor was inadvertently isolated due to the mispositioned valve and actual oil pressure could not be detected. As a result when the 3C Charging Pump was placed in service, the pump tripped as designed. The inspectors reviewed the licensees corrective actions described in the LER, reviewed the condition report, and discussed the status of continuing corrective action with appropriate personnel. Procedure 3-ONOP-047.1, Loss of Charging Flow in Modes 1 through 4, Procedure 0-ADM-205, Administrative Control of Valves, Locks, and Switches, and Procedure 0-OSP-205, Verification of Administratively Controlled Valves, Lock, and Switches, were also used in the inspectors review.
b. Findings
Introduction.
A self revealing Green NCV of Technical Specification 3.1.2.3 was identified for failure to maintain at least two charging pumps operable. This condition occurred when Isolation Valve 3-280H for the 3C Charging Pump interlock pressure control switch PS-3-201C was mispositioned closed.
Description.
On August 29, 2003, while Unit 3 was operating at full power and the 3A Charging Pump was out of service for maintenance, Operations personnel placed the 3C Charging Pump in service and the pump immediately tripped. After a second unsuccessful attempt to restart the 3C Charging Pump, it was declared inoperable and the licensee entered Technical Specification 3.1.2.3, Action, which required that with only one charging pump operable, at least two charging pumps be restored to operable status within 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> or be in at least hot standby within six hours, and cold shutdown within the next 30 hours3.472222e-4 days <br />0.00833 hours <br />4.960317e-5 weeks <br />1.1415e-5 months <br />. The licensees investigation revealed that Valve 3-280H was mispositioned in the closed position. Valve 3-280H is the instrument isolation valve for PS-3-201C, the interlock pressure control switch, and is required to be open during normal operations. Pressure Switch PS-3-201C provides a protective feature for the 3C Charging Pump that will trip the charging pump if it detects low oil pressure. Therefore, on August 29, 2003 when the Charging Pump 3C was placed in service the pump tripped as designed. The licensee immediately repositioned Valve 3-280H to the open position, restored the 3C Charging Pump to operable status, exited Technical Specification 3.1.2.3 action, and subsequently placed the pump in service.
During the investigation, the licensee could not determine when Valve 3-208H was closed. However, the licensees investigation concluded that Valve 3-280H could have been easily manipulated by accidental contact during work taking place in the immediate vicinity. Since a definite time of Valve 3-208H closure could not be determined, the licensee considered that the 3C Charging Pump was inoperable from the time the last surveillance test was performed on August 26, 2003 until it was restored on August 29, 2003. The total period of inoperability was 84 hours9.722222e-4 days <br />0.0233 hours <br />1.388889e-4 weeks <br />3.1962e-5 months <br /> which exceeded the 72 hour8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> Technical Specification Action Station 3.1.2.3 allowed outage time of 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br />.
Analysis.
The licensee failed to maintain plant configuration control in that Valve 3-280H was mispositioned closed which resulted in the 3C Charging Pump being inoperable.
This performance deficiency resulted in Unit 3 operating in a condition prohibited by Technical Specification 3.1.2.3. This finding is greater than minor because it involved the equipment performance attribute of the mitigating system cornerstone and affected the objective of ensuring that equipment is available and capable to respond to an event. Because the finding involved an actual loss of safety function of two charging pumps, for longer than the Technical Specification allowed outage time, a phase 2, Significance Determination was completed using NRC Manual Chapter 0609, Appendix A. The finding was determined to be of low safety significance (green), since one charging pump remained operable and available to perform the safety function. The most dominant core damage sequence involved the steam generator tube rupture accident. For this finding, the inspectors assumed that one charging pump was available.
Enforcement.
Technical Specification 3.1.2.3 required that At least two charging pumps shall be operable in Modes 1, 2, 3, and 4. Technical Specification 3.1.2.3 Action required that with only one charging pump operable, restore at least two charging pumps to operable status within 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> or be in at least HOT STANDBY and borated to a SHUTDOWN MARGIN equivalent to at least 1 % delta k/k at 200 degrees F within 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />... Contrary to the above, the licensee failed to maintain at least two operable charging pumps in accordance with Technical Specification 3.1.2.3, due to a mispostioned valve (Isolation valve 3-280H for the 3C Charging Pump interlock pressure control switch PS-3-201C.) As a result, 3C Charging Pump was determined to be inoperable from August 26, 2003 at 4:45 a.m. to August 29, 2003 at 16:55, a total of 84 hours9.722222e-4 days <br />0.0233 hours <br />1.388889e-4 weeks <br />3.1962e-5 months <br /> and 10 minutes which exceeded the 72 hour8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> Technical Specification Action Station 3.1.2.3 of 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br />, and constituted an operation prohibited by Technical Specifications. Because of the very low safety significance and the licensees action to place the issue in their corrective action program as Condition Report 03-2349, this violation is being treated as a non-cited violation in accordance with Section VI.A.1 of the Enforcement Policy: 05000250/2004002-03, Operation with two charging pumps inoperable in excess of technical specifications allowable limits.
.2 (Closed) LER 05000250/2003009-00, Component Cooling Water System Outside
Technical Specifications This LER identified that during a July 6, 2003 Pump In-Service Test (IST) of the Unit 3C Component Cooling Water pump (CCW) the system was placed in a configuration that resulted in a loss of safety function of the system, and failed to meet the requirements of Technical Specification (TS) 3.7.2, Component Cooling Water System. During the IST the CCW system headers are split with the 3A CCW pump aligned through one heat exchanger to the 3A header and the 3C CCW and 3B CCW pumps aligned through the other two heat exchangers to the 3B header. The 3B CCW pump control switch is placed in the pull-to-lock position, rendering it inoperable, in order to establish the required IST test flow rate for the 3C CCW pump, to the 3B header. In order for the 3C CCW pump to receive the 3B CCW pumps auto-start signals the 3B CCW pump breaker must be racked out. This will align the CCW pump auto-start logic to the 3C CCW pump. The racking out of the 3B pump breaker was not accounted for in the licensees IST procedures and as a result rendered the 3C pump incapable of auto starting as designed. This resulted in only the 3A CCW pump and one heat exchanger to mitigate a postulated accident during the IST. One CCW pump serving 1 header and 1 heat exchanger is less than the minimum required per TS 3.7.2. The licensee attributed the event to a procedural deficiency resulting in unacceptable CCW system testing configurations. The licensees corrective action was to update the IST procedure to ensure that the 3B CCW pump is not placed into pull to lock and is therefore always available to receive its auto-start logic signals during testing of the 3C CCW pump. This procedural change ensures that the system is in compliance with TS 3.7.2.
The finding is more than minor because it affected the Mitigating Systems Cornerstone objective in that CCW equipment reliability and capability were reduced and did not meet accident heat load requirements. The finding was evaluated using the SDP Phase 2 worksheets and was considered to have very low safety significance (Green), because the out of service duration was short and operator recovery of the B CCW Pump was considered credible. This licensee-identified finding involved a violation of 10CFR50, Appendix B, Criterion V, Instructions, Procedures, and Drawings. The enforcement aspects of the violation are discussed in Section 4OA7. This LER is closed.

On April 6, 2004, the resident inspectors presented the inspection results to Mr. M. Pearce and other members of his staff who acknowledged the findings. The inspectors confirmed that proprietary information was not provided or examined during the inspection.
.2 Annual Assessment Meeting Summary
On March 24, 2004, the NRCs Chief of Reactor Projects Branch 3, Public Affairs Officer, and Resident Inspector assigned to the Turkey Point Nuclear Plant met with Florida Power & Light Co. to discuss the NRCs Reactor Oversight Process (ROP) and the Turkey Point annual assessment of safety performance for the period of January 1, 2003 - December 31, 2003. The major topics addressed were: the NRCs assessment program, the results of the Turkey Point assessment, and future NRC inspection activities. Attendees included Turkey Point site management and members of site staff.
This meeting was open to the public. The NRCs presentation material used for the discussion is available from the NRCs document system (ADAMS) as accession number ML040980609. ADAMS is accessible from the NRC Web site at http://www.nrc.gov/reading-rm/adams.html (the Public Electronic Reading Room).
4OA7 Licensee-Identified Violation
The following violation of very low safety significance (Green) was identified by the licensee and is a violation of NRC requirements which meet the criteria of Section VI of the NRC Enforcement Policy, NUREG-1600, for being dispositioned as NCVs:
10CFR50, Appendix B, Criterion V, requires, in part, that activities affecting quality shall be prescribed by documented instructions, procedures, or drawings, of a type appropriate to the circumstances and shall be accomplished in accordance with these instructions, procedures, or drawings. Contrary to the above, on July 18, 2003, the licensee identified that due to an inadequate in-service test procedure, the CCW system was placed into a configuration, during in-service testing of the 3C CCW Pump, which resulted in the plant being in a condition that could have prevented the CCW system from being able to adequately cool down the plant. With only the 3A CCW Pump (100
% capacity) supplying one CCW heat exchanger (50 % capacity) the CCW system safety function, of providing heat removal capability for analyzed accidents, was not assured. This was identified in the licensee s corrective action program as Condition Report 03-1563. This finding was determined to be of very low safety significance (Green) using the SDP Phase 2 worksheets, because of the short duration of the past testing activities of the 3C CCW Pump, and the ability for immediate operator recovery of the B CCW Pump.
