SUBJECT:
ST. LUCIE NUCLEAR PLANT - NRC INTEGRATED INSPECTION REPORT 05000335/2005005 AND 05000389/2005005
Dear Mr. Stall:
On December 31, 2005, the US Nuclear Regulatory Commission (NRC) completed an inspection at your St. Lucie Units 1 and 2. The enclosed integrated inspection report documents the inspection findings which were discussed on January 4, 2006, with Mr. Jefferson 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.
This report documents four inspector identified findings and two self-revealing findings, all of very low safety significance (Green). These findings were determined to involve violations of NRC requirements. Additionally, two licensee identified violations, which were determined to be of very low safety significance, are listed in this report. However, because of the very low safety significance and because they were entered into your corrective action program, the NRC is treating these violations as non-cited violations (NCVs), in accordance with Section VI.A of the NRCs Enforcement Policy. If you contest these NCVs, 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 Resident Inspector at the St. Lucie 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 05000335/2005-05, 05000389/2005-05; 10/01/2005 - 12/31/2005; St. Lucie Nuclear Plant, Units 1 & 2; Refueling and Other Outage Activities, Inservice Inspection Activities, Radiation Safety, and PI&R Annual Sample Review.
The report covered a three month period of inspection by resident inspectors and several other inspectors from Region II. Six Green non-cited violations (NCVs) were identified. The significance of most findings is identified by their color (Green, White, Yellow, Red) using IMC 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 NRC's program for overseeing the safe operation of commercial nuclear power reactors is described in NUREG-1649, Reactor Oversight Process, Revision 3, dated July 2000.
A. NRC- Identified and Self-Revealing Findings Cornerstone: Initiating Events
- Green. A self-revealing NCV of Technical Specification 6.8.1.b, Refueling Operations, was identified when the licensee failed to properly implement system operating procedure NOP-03.05, Placing the 1B SDC System in Operation while attempting to restore reactor plant shutdown cooling (SDC)
flow. As a result a low pressure safety injection (LPSI) pump was started with its suction valve closed which caused the pump to cavitate. This finding had human performance cross-cutting aspects in that an operator failed to comply with procedural requirements.
This finding is greater than minor because it is associated with the configuration control and human performance attributes of the Initiating Events cornerstone and adversely impacted the cornerstone objective of limiting the likelihood of those events that upset plant stability and challenge critical safety functions during shutdown operations. In addition, if left uncorrected, this finding would result in a more significant safety concern. The inspectors evaluated the finding using Inspection Manual Chapter (IMC) 0609, Appendix G, Attachment 1, Checklist 3, "Pressurized Water Reactor (PWR) Refueling Operations with RCS Open and Refueling Cavity Level < 23 feet. The finding affected one train of decay heat removal (DHR) which was required to be operable; therefore, the finding did not screen out in Phase 1. Subsequently, the Region II SRA evaluated the finding using the IMC 609, Appendix G, Attachment 2, Phase 2 Significance Determination Process Template for PWR During Shutdown. This finding was a precursor finding that has the potential to cause a loss of the operating train of DHR. The Phase 2 SDP evaluation determined the finding to be of very low safety significance (Green) because the required operating SDC train was only briefly interrupted; the standby SDC train was promptly placed in service; and the affected train was quickly restored. The licensee took prompt action to enter the item into their corrective action program and implement interim corrective actions. The cause of the finding is related to the cross-cutting element of human performance. (Section 1R20)
Enclosure
- Green. A NCV of TS 6.8.1.f, Fire Protection Program Implementation, was identified by the inspectors during a trend review of multiple small fires in the Unit 1 containment building during outage hot work (air arc gouging) activities. The inspectors determined that the licensee failed to take timely and effective corrective actions to control hot work activities. The licensee entered the issue into their CAP as Condition Report (CR) 2005-33661. This CR requires a comprehensive common cause analysis by a cross-functional team, which will examine the various fire protection issues identified, to determine whether or not a generic fire protection programmatic weakness is present.
This finding is greater than minor because it is associated with the protection against external factors attribute of the Initiating Events cornerstone and adversely impacted the cornerstone objective of limiting the likelihood of those events that upset plant stability and challenge critical safety functions during shutdown operations. In addition, if left uncorrected, this finding would result in a more significant safety concern. The inspectors determined that the finding was associated with fire prevention and administrative controls and assigned a low degradation rating. As a result of the phase 1 screening, this finding was determined to be of very low safety significance. The cause of the finding is related to the cross-cutting element of problem identification and resolution, specifically involving incomplete corrective actions. (Section 4OA2)
- Green. The inspectors identified a NCV of 10 CFR 50, Appendix B, Criterion V, Instructions, Procedures and Drawings. Licensee activities affecting quality were not accomplished in accordance with site procedures GMP-05, ADM 02.01, and QI 13/PSL2, in that a steel file that had been previously used on carbon steel material was used during weld preparation on FT-08-1A, Unit 2 Main Steam flow transmitter, which is a stainless steel, ASME Class 2, pressure boundary component. Licensee procedures specifically prohibit the use of carbon steel contaminated tools on stainless steel. The licensee failed to meet procedural requirements by not maintaining control of files, wire brushes, and grinding wheels issued from the tool room inside the Radiation Controlled Area. The licensee immediately entered the finding into their corrective action system, and conducted stand-down meetings with site welding personnel regarding the procedure requirements. The licensee decided to not install the contaminated tubing, and made new repair welds with new stainless steel base material, new wire brushes, and other new tools.
This finding is greater than minor because if the finding was left uncorrected, it could become a more significant safety concern in that the contamination of the stainless steel base metal and weld with carbon steel particles could lead to localized outside diameter initiated pitting corrosion that would increase the likelihood of a through-wall pressure boundary leak. Additionally, the finding affected the equipment performance attribute of the Reactor Safety / Initiating Event Cornerstone objective to limit the likelihood of those events that upset plant stability and challenge critical safety functions during shutdown as well as power operations. This finding was determined to be of very low safety Enclosure
significance based on the IMC 0609, Appendix A, Phase 1 SDP worksheet and is associated with the initiating event cornerstone. The carbon steel contamination of FT-08-1A did not contribute to the increased likelihood of a primary or secondary loss of coolant accident (LOCA), and the finding did not contribute to either the likelihood of a reactor trip or the likelihood that mitigation equipment or functions will not be available; therefore, the finding screened as Green. A contributing cause of the finding is related to the cross-cutting element of human performance. (Section 1R08)
Cornerstone: Mitigating Systems
- Green. A NCV was identified by the inspectors for the failure to comply with 10 CFR 50, Appendix B, Criterion V, Instructions, Procedures and Drawings. As a result of plant personnel failing to follow site procedures, a bucket containing sheets of paper, tools, and other miscellaneous items were brought inside the Unit 2 reactor containment buliding (RCB), and were not listed in the foreign material exclusion (FME) log book. Upon identification of this deficiency, the licensee immediately entered the RCB and logged the bucket and all of its contents in the FME log book. Licensee management also conducted a detailed containment close out inspection prior to the restart of Unit 2.
This finding is more than minor because foreign material left inside containment can be transported to the containment sump and cause restriction of the ECCS pump suction during LOCA conditions. Additionally, this finding is associated with the equipment performance attribute of the Mitigating Systems Cornerstone objective to ensure the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences (i.e., core damage). This finding was determined to be of very low safety significance (Green) based on the IMC 0609, Appendix A, Phase 1 SDP worksheet. This loss of FME control was not a design or qualification deficiency confirmed to result in loss of ECCS function per GL 91-18, nor did it represent an actual loss of a system safety function or the loss of a single train; therefore, the finding screened as Green. The inspectors determined that the human error which resulted in failure to properly document the material in the FME log was related to the human performance cross-cutting area. (Section 1R20)
Cornerstone: Occupational Radiation Safety
- Green. A self-revealing NCV of Technical Specification (TS) 6.11 was identified for failure to implement adequate radiological controls for work near contaminated pressurizer components as required by Health Physics Procedure (HPP)-3, High Radiation Areas, Rev. 17A. On November 25, 2005, two individuals entered the Unit 1 (U1) pressurizer cubicle to perform a visual inspection of valve V1249 and subsequently became contaminated due to failure to follow Radiation Work Permit (RWP) requirements and inadequate Health Physics Technician (HPT) coverage.
Enclosure
This finding is greater than minor because it is associated with the Occupational Radiation Safety Cornerstone attribute of exposure/contamination control and adversely affects the cornerstone objective of ensuring adequate protection of worker health and safety from exposure to radiation from radioactive material during routine civilian nuclear reactor operations. The failure to implement required RWP controls for high radiation area or highly contaminated area work activities could result in unintended exposures. The finding was determined to be of very low safety significance because the individuals were monitored for exposures from external radiation fields and from internally deposited radionuclides, as appropriate; and no individuals exceeded either internal or external exposure limits. The finding involved the cross-cutting aspect of Human Performance because the contamination events were a direct result of worker and HPT failures to implement required radiological controls. The licensee entered this finding in its corrective action program (CAP) as CR 2005-32859.
(Section 2OS1).
Cornerstone: Public Radiation Safety
- Green. The inspectors identified a NCV of 10 CFR 71.5 for failure to follow Department of Transportation (DOT) regulations for proper closure of Type A shipping packages. Specifically, for Type A packages containing in-core instrument cutting equipment shipped on October 3, 2003 and February 17, 2005, the licensee failed to prepare the package closures in accordance with the container vendor specifications as required by DOT 49 CFR 173.475 (e).
The finding was more than minor because it is associated with the Public Radiation Safety Cornerstone program and process attribute involving transportation procedures. The cornerstone objective to ensure adequate protection of public health and safety from exposure to radioactive material released into the public domain was affected because the identified issue involved shipments of radioactive material that were contrary to NRC and DOT regulations. The finding is of very low safety significance (Green) because it did not involve a radiation limit being exceeded or a package being breached. This finding also involved the cross-cutting aspect of problem identification and resolution regarding implementation of Operating Experience (OE). Although the licensee had reviewed OE 19531 associated with lid bolting torque for a Type A package they did not enter this OE into their CAP process and implement actions to prevent similar occurrences. After inspector identification of the issue, the licensee entered this finding into the CAP as CR 2005-25727 (Section 2PS2).
Enclosure
B. Licensee-Identified Violations Violations of very low safety significance, which were identified by the licensee have been reviewed by the inspectors. Corrective actions taken or planned by the licensee have been entered into the licensees CAP. These violations and corrective actions are listed in Section 4OA7 of this report.

Report Details Summary of Plant Status Units 1 and 2 began the report period at full Rated Thermal Power (RTP). Unit 1 was shutdown on October 17, 2005, for scheduled refueling outage (RFO) 20. Unit 1 completed RFO 20 and returned to full RTP on December 22, 2005, where it remained throughout this report period.
Unit 2 was shutdown due to the approach of hurricane Wilma on October 30, 2005. Unit 2 returned to full RTP on November 2, 2005, where it remained throughout this report period.
1. REACTOR SAFETY Cornerstones: Initiating Events, Mitigating Systems, and Barrier Integrity 1R01 Adverse Weather Protection a. Inspection Scope On October 21 and 23, the inspectors reviewed and verified licensee actions taken in accordance with their procedural requirements prior to the onset of hurricane Wilma.
The inspectors observed plant conditions, evaluating those conditions using criteria documented in Administrative Procedure ADM-04.01, Revision 12, Hurricane Season Preparation. The inspectors performed site walkdowns and plant tours to verify the licensee had made the required preparations. The inspectors performed reviews of plant exterior areas vulnerable to high winds and hurricane conditions including the following areas:
- Turbine Building
- Intake Cooling Water (ICW) Basin b. Findings No findings of significance were identified.
1R04 Equipment Alignment a. Inspection Scope
.1 Partial Equipment Walkdowns The inspectors conducted three partial equipment alignment verifications of the safety-related systems listed below to review the operability of required redundant trains or backup systems while the other trains were inoperable or out of service (OOS). The inspectors attempted to identify any discrepancies that could impact the function of the system, and therefore, potentially increase risk. These inspections included reviews of applicable Technical Specifications (TS), plant lineup procedures, operating procedures, and/or piping and instrumentation drawings (P&ID), which were compared with observed equipment configurations. The inspectors also reviewed applicable reactor control Enclosure
operator (RCO) logs; out of service and operator work around (OWA) lists; active temporary system alterations (TSA); and any outstanding condition reports (CRs)
regarding system alignment and operability.
- Unit 1 Shutdown Cooling System Train B
- 1A Vital Electrical Switchgear b. Findings No findings of significance were identified.
.2 Complete Equipment Walkdown a. Inspection Scope During the week of December 5, the inspectors completed a detailed alignment verification of the Unit 1 Component Cooling Water (CCW) system using P&ID 8770-G-083, Component Cooling System, and applicable procedures to walkdown and verify equipment alignment. The inspectors reviewed relevant portions of the Updated Final Safety Analysis Report (UFSAR) and TS, and interviewed the responsible system engineer. The inspectors also verified electrical power requirements, component labeling, pipe hangers and support installation, and associated support systems status.
The walkdown also included evaluation of system piping and supports to verify that: 1)
piping and pipe supports did not show evidence of water hammer; 2) oil reservoir levels indicated normal; 3) snubbers did not indicate any observable hydraulic fluid leakage; 4)
hangers were within the setpoints; and 5) component foundations were not degraded.
Furthermore, the inspectors examined equipment out of service lists; active open work orders (WO); the CCW system health report; and any CRs that could affect system alignment and operability.
b. Findings No findings of significance were identified.
1R05 Fire Protection
.1 Fire Protection - Tours a. Inspection Scope The inspectors conducted tours of the eight areas listed below to verify they conformed with procedure AP-1800022, Revision 38C, Fire Protection Plan. The inspectors specifically examined any transient combustibles in the areas and any ongoing hot work or other potential ignition sources. The inspectors also assessed whether the material condition, operational status, and operational lineup of fire protection systems, equipment and features were in accordance with the Fire Protection Plan. Furthermore, Enclosure
the inspectors evaluated the use of any compensatory measures being performed in accordance with the licensees procedures and Fire Protection Plan.
- Unit 2 ICW Structure
- Unit 1 Control Room Area
- Unit 1 Containment 18' Elevation
- Unit 1 Auxiliary Feedwater (AFW) Structure
- Unit 1 Containment 7.5' Elevation
- Unit 2 Boric Acid Tank Room
- Unit 2 Emergency Core Cooling System (ECCS) Room
- Unit 2 Condensate Storage Tank Enclosure b. Findings No findings of significance were identified.
.2 Fire Protection - Drill Observation a. Inspection Scope The inspectors observed a fire drill conducted in the Unit 1 Cable Spreading Room on December 5, 2005. The drill was observed to evaluate the readiness of the plant fire brigade to fight fires. The inspectors verified that the licensee staff identified deficiencies, openly discussed them in a self-critical manner at the debrief, and took appropriate corrective actions as required. Specific attributes evaluated were: (1)
proper wearing of turnout gear and self-contained breathing apparatus; (2) proper use and layout of fire hoses; (3) employment of appropriate fire fighting techniques; (4)
sufficient fire fighting equipment brought to the scene; (5) effectiveness of command and control; (6) search for victims and propagation of the fire into other plant areas; (7)
smoke removal operations; (8) utilization of pre-planned strategies; (9) adherence to the pre-planned drill scenario; and (10) drill objectives.
b. Findings No findings of significance were identified.
1R06 Flood Protection Measures a. Inspection Scope Internal Flooding The inspectors reviewed UFSAR Section 3.4, Water Level (Flood) Design and UFSAR Table 3.2-1, Design Classification of Structures, System and Components, and that specific equipment and components in the Unit 1 ECCS pump room (i.e., HPSI, LPSI, and CS systems) that were susceptible to damage from flooding met the stated requirements. The inspectors also reviewed procedure 1-ONP-24.01, Reactor Auxiliary Enclosure
Building Flooding, and verified certain actions required to be taken could be accomplished as written. The inspectors reviewed the Unit 1 ECCS pump room sump level indication and control system preventative maintenance (PM) schedule. The inspectors also verified the corrective action program (CAP) was being used to identify equipment issues that could be impacted by potential internal flooding.
b. Findings No findings of significance were identified.
1R07 Heat Sink Performance a. Inspection Scope During the recent Unit 1 RFO, the inspectors observed the re-tubing activities of the 1A and 1B CCW heat exchangers. The inspectors also reviewed applicable Eddy Current Testing (ECT) procedures, equipment calibration records, and CCW Heat Exchanger Component Specific Technique Sheets. Furthermore, the inspectors also interviewed the responsible system engineer and reviewed the records and documentation indicating that the frequency of inspection was sufficient to detect degradation to ensure TS operability prior to loss of heat removal capabilities below design basis values.
b. Findings No findings of significance were identified.
1R08 Inservice Inspection (ISI) Activities
.1 Piping Systems ISI a. Inspection Scope From October 31 through November 4, 2005, the inspectors observed and reviewed the implementation of the licensees ISI program for monitoring degradation of the reactor coolant system (RCS) boundary and the risk significant piping system boundaries for Unit 1. The inspectors selected a sample of American Society of Mechanical Engineers (ASME), Boiler and Pressure Vessel Code,Section XI required examinations and code components in order of risk priority as identified in Section 71111.08-03 of inspection procedure 71111.08, Inservice Inspection Activities, based upon the ISI activities available for review during the onsite inspection period. The inspectors reviewed the Owners Activity Reports (OAR) for the last two refueling outages.
The inspectors conducted an on-site review of nondestructive examination (NDE)
activities to evaluate the licensees compliance with TS; ASME Section XI and Section V, 1989 Edition with no Addenda for Class 1, 2, and 3 systems. For Unit 1, this was the first outage of the third period of the third interval. The inspectors verified that indications and defects were appropriately evaluated and dispositioned in accordance Enclosure
with the applicable requirements of ASME Section XI. Specifically, the inspectors observed the following examination:
Ultrasonic Testing (UT):
- 1-SGA-W5, Steam Generator 1A Primary Side Inlet Nozzle to Shell Weld, ASME Class 1 Specifically, the inspectors reviewed the following examination records:
Ultrasonic Testing (UT):
- RC-103-FW-2004, Preservice Inspection (PSI) of Tee to Reducer on Combined Pressurizer Spray Line Tee, ASME Class 1
- SI-105-3-SW-2, Pipe to Elbow, HPSI Pump 1A to Header 1A, ASME Class 2
- SI-105-4-SW-2, Pipe to Elbow, HPSI Pump 1A to Header 1A, ASME Class 2
- SI-105-4-SW-1, Elbow to Pipe, HPSI Pump 1A to Header 1A, ASME Class 2 Radiographic Examination (RT)
- RC-103-FW-2004, PSI of Tee to Reducer (#176) on Combined Pressurizer Spray Line Tee, Stainless Steel, ASME Class 1
- RT-450-00, SC 008, Pressurizer Spray Nozzle Repair, Carbon Steel to Stainless Steel, ASME Class 1
- W-123, 4" Pressurizer Spray Line Tee, ASME Class 1 Qualification and certification records for examiners, inspection equipment, and consumables along with the applicable NDE procedures for the above ISI examination activities were reviewed and compared to requirements stated in ASME Section V and Section XI.
The inspectors reviewed the licensees operating experience assessment for issues associated with the Mihama-3 pipe rupture event of August 9, 2004. This pipe failure was attributed to Flow Accelerating Corrosion (FAC), and the inspectors held discussions with licensee personnel regarding their FAC program. The inspectors reviewed the licensees evaluation for a FAC location that had a degraded wall thickness measurement. The inspectors reviewed information to determine that the licensee had entered this condition into their CAP, and that they were taking appropriate actions to ensure that the subject piping would have enough wall thickness to meet structural requirements for the duration of the next operating cycle.
Specifically, the inspectors reviewed the following weld records that contained recordable indications from previous examinations:
- FAC Component 12ES1-P-7-16 (Location 13), High Pressure Extraction Steam to Feedwater Heater 5A
- RT Weld Number W-119, Pressurizer Spray Line Tee, ASME Class 1
- RT Weld Number W-175, Pressurizer Spray Line Tee, ASME Class 1 Enclosure
Pressure boundary welding associated with one ASME Class 2 component, Unit 2 vent assembly for flow instrument FT-08-1A, was reviewed by the inspectors to verify the welding process and preservice examinations were performed in accordance with the requirements of ASME Code Sections III, V, IX, and XI. The inspectors reviewed weld data sheets, the welding procedure specification (WPS), and supporting welding procedure qualification records (PQR) for the following weld:
- Weld Joint 02037, GTAW Fillet Weld, ASME Class 2, Main Steam Flow Element The inspectors performed a review of ISI related problems that were identified by the licensee and entered into the CAP. The inspectors reviewed these corrective action documents to confirm that the licensee had appropriately described the scope of the problems. Additionally, the inspectors review included confirmation that the licensee had an adequate threshold for identifying issues, and had implemented effective corrective actions. Through interviews with licensee staff and review of CRs, the inspectors evaluated the licensees threshold for identifying lessons learned from industry issues related to ASME Section XI. The inspectors performed these reviews to ensure compliance with 10CFR Part 50, Appendix B, Criterion XVI, Corrective Action, requirements. The corrective action documents reviewed by the inspectors are listed in the attachment to this report.
b. Findings Introduction: A Green inspector identified Non-Cited Violation (NCV) was identified for the failure to comply with 10 CFR 50, Appendix B, Criterion V, Instructions, Procedures and Drawings. As a result of plant personnel failing to follow site procedures, a steel file that had been previously used on carbon steel material was used during weld preparation on a safety-related, stainless steel, ASME Class 2, pressure boundary component. Licensee procedures GMP-05, ADM 02.01, and QI 13/PSL2 all contain similar requirements that prohibit the use of carbon steel contaminated steel files, grinding wheels, and wire brushes on stainless steel components.
Description: On Tuesday, October 25, 2005, the inspectors observed licensee personnel grinding on a stainless steel component with a steel file that had previously been used on carbon steel material. This observation was made during weld preparation activities for the replacement of 1/2 inch tubing associated with the Unit 2 Main Steam flow transmitter, FT-08-1A. A steam leak was identified by the licensee in this ASME Class 2 weld during a Mode 3 walk-down, while the plant was shutdown for Hurricane Wilma.
Plant personnel associated with this work were not aware of the procedural requirements that prohibit the use of tools that may have been previously used on carbon steel material for use on stainless steel components. The workers associated with this replacement activity stated that they received the file from the hot tool room inside the Radiation Controlled Area (RCA). If this failure to implement procedural requirements was left uncorrected, contamination of stainless steel welds and base metal would continue. This contamination of stainless steel base material with carbon steel particles could lead to the increased likelihood of outside diameter initiated pitting and subsequent pressure boundary leaks. Additionally, if a weld fit up area was Enclosure
contaminated with carbon steel particles, the weld joint could become diluted and not maintain the proper mechanical properties as specified in its design requirements.
Procedures QI 13/PSL-2 entitled Housekeeping and Cleanliness Control, ADM 02.01, Control of Chemicals and Materials for the Maintenance of Plant Systems, GMP-05, Control of Welding Special Processes, and the Florida Power and Light Weld Control Manual, all contain requirements that grinding wheels, files, and wire brushes for stainless steel and nickel-based alloys shall not have been previously used on carbon or low alloy steels.
The licensee issued CR 2005-28906 for the performance deficiency identified by the inspectors. Upon identification of this deficiency, the licensee conducted a stand-down meeting with site welders and instructed them on the requirements of the procedures.
The licensee decided to not install the contaminated tubing, and made new repair welds with new stainless steel base material, new wire brushes, and other new tools.
Analysis: The performance deficiency associated with this inspector-identified NCV was that licensee activities affecting quality were not accomplished in accordance with site procedures GMP-05, ADM 02.01, and QI 13/PSL2, in that a steel file that was contaminated with carbon steel particles was used on a safety-related, stainless steel, ASME Class 2, pressure boundary component. This failure to implement procedural requirements should have been prevented and was reasonably within the licensees ability to foresee, identify, and correct.
In accordance with Inspection Manual Chapter (IMC) 0612, Appendix B, this finding is greater than minor because if the finding was left uncorrected, it could become a more significant safety concern in that the contamination of the stainless steel base metal and weld with carbon steel particles could lead to localized outside diameter initiated pitting corrosion that would increase the likelihood of a through-wall pressure boundary leak.
Additionally, the finding affected the equipment performance attribute of the Reactor Safety / Initiating Event Cornerstone objective to limit the likelihood of those events that upset plant stability and challenge critical safety functions during shutdown as well as power operations.
This finding was determined to be of very low safety significance based on the IMC 0609, Appendix A, Phase 1 Significance Determination Process (SDP) worksheet. The finding is associated with the initiating event cornerstone. The carbon steel contamination of FT-08-1A did not contribute to the increased likelihood of a primary or secondary loss of coolant accident (LOCA), and the finding did not contribute to either the likelihood of a reactor trip or the likelihood that mitigation equipment or functions will not be available; therefore, the finding screened as Green.
The inspectors determined that a contributing cause of this finding was related to the human performance cross-cutting area, in that the licensee did not maintain appropriate tools for use in the hot tool room applicable to stainless steel, and the personnel responsible for issuing tools to be used on stainless steel were not aware of the procedural requirements.
Enclosure
Enforcement: 10 CFR 50, Appendix B, Criterion V, requires, in part, that activities affecting quality shall be prescribed by documented instructions, procedures, and drawings, of a type appropriate to the circumstances and shall be accomplished in accordance with these instructions, procedures, or drawings. The licensee implements this requirement, in part, through procedures GMP-05, ADM 02.01, and QI 13, which all contain similar statements as quoted below: Grinding wheels and brushes for stainless steel and nickel-based alloys shall not have been previously used on carbon or low alloy steels. Contrary to the above, on October 25, 2005, it was determined that the licensee had failed to accomplish weld repair activities in accordance with procedure requirements as stated in GMP-05, ADM 02.01, and QI 13, in that grinding on stainless steel components was performed using a file that had previously been used on carbon steel material.
This violation is associated with an inspection finding that is characterized by the Significance Determination Process as having very low risk significance (Green) and is in the licensees CAP as CR 2005-28906. This violation is being treated as a NCV, consistent with Section VI.A of the NRC Enforcement Policy: NCV 50-389/2005-05-01, Failure to Control Tooling for Use Only on Stainless Steel
.2 Boric Acid Corrosion Control (BACC) ISI a. Inspection Scope From October 31 through November 4, 2005, the inspectors reviewed the licensees Boric Acid Corrosion Control Program (BACCP) to ensure compliance with commitments made in response to NRC Generic Letter 88-05 Boric Acid Corrosion of Carbon Steel Reactor Pressure Boundary, and Bulletin 2002-01 Reactor Pressure Vessel Head Degradation and Reactor Coolant Pressure Boundary Integrity.
The inspectors conducted an on-site record review, and an independent walk-down of the Reactor Containment Building (RCB), which is not normally accessible during at-power operations, to evaluate compliance with BACCP requirements and 10 CFR Part 50, Appendix B, Criterion XVI, Corrective Action, requirements. In particular, the inspectors verified that the licensees visual examinations focused on locations where boric acid leaks could cause degradation of safety significant components and that degraded or non-conforming conditions were properly identified in the licensees CAP.
The inspectors reviewed a sample of engineering evaluations completed for boric acid found on RCS piping and other ASME code class components to verify that the minimum design code required section thickness had been maintained for affected components. The inspectors also reviewed licensee CRs initiated for evidence of boric acid leakage to confirm that they were consistent with requirements of Section XI of the ASME Code, 10 CFR 50 Appendix B Criterion XVI, and licensee BACCP procedures.

1R20 Refueling and Other Outage Activities a. Inspection Scope Outage Planning, Control and Risk Assessment During pre-outage planning, the inspectors reviewed the risk reduction methodology employed by the licensee for SL1-20, in particular the Risk Assessment Team (RAT)
notebook. The inspectors also examined the licensees implementation of shutdown safety assessments during SL1-20 in accordance with Administrative Procedure 0-AP-010526, Outage Risk Assessment and Control, to verify whether a defense in depth concept was in place to ensure safe operations and avoid unnecessary risk.
Furthermore, the inspectors regularly monitored outage planning and control activities in the Outage Control Center (OCC), and interviewed responsible OCC management, during the outage to ensure SSC configurations and work scope were consistent with TS requirements, site procedures, and outage risk controls.
Monitoring of Shutdown Activities The inspectors witnessed the shutdown and cooldown of Unit 1 beginning on October 17, 2005. The inspectors also monitored plant parameters and verified that shutdown activities were conducted in accordance with TS and applicable operating procedures, such as: 1-GOP-123, Turbine Shutdown - Full Load to Zero Load; 1-GOP-203, Reactor Shutdown; 1-GOP-305, Reactor Plant Cooldown - Hot Standby To Cold Shutdown; and 1-NOP-03.05, Shutdown Cooling.
Outage Activities The inspectors examined outage activities to verify that they were conducted in accordance with TS, licensee procedures, and the licensees outage risk control plan.
Some of the more significant inspection activities accomplished by the inspectors were as follows:
Enclosure
- Walked down selected safety-related equipment clearance orders
- Verified operability of RCS pressure, level, flow, and temperature instruments during various modes of operation
- Verified electrical systems availability and alignment
- Reviewed actions taken in preparation for Hurricane Wilma
- Verified shutdown cooling system and spent fuel pool cooling system operation
- Evaluated implementation of reactivity controls
- Reviewed control of containment penetrations
- Examined FME controls put in place inside containment (e.g., around the refueling cavity, near sensitive equipment and RCS breaches) and around the spent fuel pool (SFP)
Refueling Activities and Containment Closure The inspectors witnessed selected fuel handling operations being performed according to TS and applicable operating procedures from the main control room, refueling cavity inside containment and the SFP. The inspectors also examined licensee activities to control and track the position of each fuel assembly. Furthermore, the inspectors evaluated the licensees ability to close the containment equipment, personnel, and emergency hatches in a timely manner per procedure 1-MMP-68.02, Containment Closure.
Heatup, Mode Transition, and Reactor Startup Activities The inspectors examined selected TS, license conditions, license commitments and verified administrative prerequisites were being met prior to mode changes. The inspectors also reviewed measured RCS leakage rates, and verified containment integrity was properly established. The inspectors performed a detailed RCB sump closeout inspection prior to plant heat up operations. The inspectors also conducted a thorough RCB walkdown on December 17 after the Unit 1 reactor plant had reached Mode 3 and was at normal operating pressure and temperature. The results of low power physics testing were discussed with Reactor Engineering and Operations personnel to ensure that the core operating limit parameters were consistent with the design. The inspectors witnessed portions of the RCS heatup, reactor startup and power ascension in accordance with the following plant procedures:
- Pre-operational Test Procedure (POP) 1-3200088
- Unit 1 Initial Criticality Following Refueling
- POP 0-3200092, Reactor Engineering Power Ascension Program

- 1-GOP-403, Reactor Plant Heatup - Mode 4 to Mode 3
- 1-GOP-504, Reactor Plant Heatup - Mode 5 to Mode 4 Enclosure
Correction Action Program The inspectors reviewed CRs generated during SL1-20 to evaluate the licensees threshold for initiating CRs. The inspectors reviewed CRs to verify priorities, mode holds, and significance levels were assigned as required. Resolution and implementation of corrective actions of several CRs were also reviewed for completeness. The inspectors routinely reviewed the results of Quality Assurance (QA)
daily surveillances of outage activities.
b. Findings
.1 Shutdown Cooling Operations Introduction: A Green self-revealing NCV of Technical Specification 6.8.1.b, Refueling Operations, was identified when the licensee failed to properly implement system operating procedure NOP-03.05, Placing the 1B SDC System in Operation while attempting to restore reactor plant shutdown cooling (SDC) flow. As a result a LPSI pump was started with its suction valve closed which caused the pump to cavitate. This finding had human performance cross-cutting aspects in that an operator failed to comply with procedural requirements.
Description: On October 28 at 11:30 pm, while Unit 1 was in a scheduled RFO, the licensee started the 1B LPSI pump in the SDC mode of operation with its suction valve closed causing the pump to cavitate. Prior to starting the pump the SRO checked the control room operating board and misinterpreted the actual position of the suction valve, V3651, and thought it was open when it actually indicated closed. The SRO then directed the reactor operator (RO) to start the 1B SDC pump who did so without checking his panel for a proper system valve lineup. Upon starting the pump the operator immediately noticed pump flow and motor amperage were abnormal and stopped the pump. The 1A SDC train was then placed into service. The licensee subsequently conducted pump venting, vibration measurement analysis, and a pump full flow test and concluded the pump was not damaged and was operable.
Analysis: The inspectors determined that starting the 1B LPSI pump with its suction valve closed was a performance deficiency requiring a significance evaluation in accordance with IMC 0612, Power Reactor Inspection Reports, Appendix B, Issue Screening. The inspectors determined that the finding was more than minor because it was associated with the configuration control and human performance attributes of the Initiating Events cornerstone and adversely impacted the cornerstone objective of limiting the likelihood of those events that upset plant stability and challenge critical safety functions during shutdown operations. In addition, if left uncorrected, this finding could result in a more significant safety concern.
The inspectors evaluated the finding using IMC 0609, Appendix G, Attachment 1, Checklist 3, "Pressurized Water Reactor (PWR) Refueling Operations with RCS Open and Refueling Cavity Level < 23. The finding affected one train of decay heat removal (DHR) which was required to be operable; therefore, the finding did not screen out in Phase 1. Subsequently, the Region II SRA evaluated the finding using the IMC 609, Enclosure
Appendix G, Attachment 2, Phase 2 Significance Determination Process Template for PWR During Shutdown. This finding was a precursor finding that has the potential to cause a loss of the operating train of DHR. The Phase 2 SDP evaluation was performed for the LORHR initiator in POS 2 with at least 3 hours3.472222e-5 days <br />8.333333e-4 hours <br />4.960317e-6 weeks <br />1.1415e-6 months <br /> to core damage upon a complete loss of SDC. The secured SDC train was recoverable and other decay heat removal trains were available. The Phase 2 SDP evaluations determined the finding to be of very low safety significance (Green).
The inspectors determined that the operability of the pump had not been adversely impacted since the pump was operated in this condition for a minute or less, subsequent engineering evaluations and inspections determined the pump was not damaged, and a full flow test was performed satisfactorily.
Enforcement: Technical Specification 6.8.1.b, Refueling Operations, requires, in part, that written procedures covering refueling operations shall be implemented. Contrary to the above, on October 28, 2005, the operators failed to implement operating procedure NOP-03.05, Placing the 1B SDC System in Operation step 6.4.5, which instructed the operators to ensure valve V3651 was open prior to starting the 1B LPSI pump. The licensee provided remedial training to those operators involved and entered the event into their CAP as CR 2005-29297. Because the failure to implement prescribed procedure steps was of very low safety significance and had been entered into the licensees CAP, this violation is being treated as a NCV, consistent with Section VI.A of the NRC Enforcement Policy: NCV 05000335/2005005-02: Failure to Implement Prescribed Procedure Steps Resulting in Starting the 1B LPSI Pump With its Suction Valve Closed.
.2 Foreign Material Exclusion Program Review Introduction: A Green NCV was identified by the inspectors for the failure to comply with 10 CFR 50, Appendix B, Criterion V, Instructions, Procedures and Drawings. As a result of plant personnel failing to follow site procedures, a bucket containing sheets of paper, tools, and other miscellaneous items were brought inside the Unit 2 RCB, and were not listed in the FME log book.
Description: On October 26, 2005, the inspectors conducted an independent walk-down of the Unit 2 RCB while the plant was in Mode 3. The inspectors observed that the licensee had failed to log a five gallon bucket and its contents in the required FME log book, which was located outside of the RCB personnel airlock. Licensee procedure ADM-27.13, Foreign Material Exclusion, requires that all materials that are taken into an FME-1 Area shall be logged in and out if tool control logging is in effect. This procedure stipulates that tool control logging shall be in effect for FME-1 Areas, and the entire RCB is considered to be an FME-1 Area during Modes 1, 2, 3, and 4.
Because these items were not listed on the FME log, and the licensee did not intend to do a final inspection of the RCB prior to Unit 2 restart, this bucket and all of its contents could have been left inside the RCB. The licensee issued CR 2005-28985 and CR 2005-29019 for the performance deficiency identified by the inspectors. Upon identification of this deficiency, the licensee immediately entered the RCB and logged Enclosure
the bucket and all of its contents in the FME log book. Licensee management also conducted a detailed containment close out inspection prior to the restart of Unit 2.
Analysis: The performance deficiency associated with this inspector-identified NCV was that licensee activities affecting quality were not accomplished in accordance with site procedure ADM-27.13, in that a bucket containing sheets of paper, tools, and other miscellaneous items were left unattended inside the Unit 2 RCB, and were not listed in the FME log book. This failure to implement procedural requirements could have been prevented and was reasonably within the licensees ability to foresee, identify, and correct.
In accordance with IMC 0612, Appendix B, this finding is more than minor because foreign material left inside containment could potentially be transported to the containment sump and cause restriction of the ECCS pump suction during LOCA conditions. Additionally, this finding is associated with the equipment performance attribute of the Mitigating Systems Cornerstone objective to ensure the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences (i.e., core damage).
This finding was determined to be of very low safety significance (Green) based on the IMC 0609, Appendix A, Phase 1 SDP worksheet. The finding affected components associated with the mitigating systems cornerstone. This loss of FME control was not a design or qualification deficiency confirmed to result in loss of ECCS function per GL 91-18, nor did it represent an actual loss of a system safety function or the loss of a single train; therefore, the finding screened as Green.
The inspectors determined that the human error, which resulted in failure to properly document the material in the FME log, was related to the human performance cross-cutting area.
Enforcement: 10 CFR 50, Appendix B, Criterion V, requires, in part, that activities affecting quality shall be prescribed by documented instructions, procedures, and drawings, of a type appropriate to the circumstances and shall be accomplished in accordance with these instructions, procedures, or drawings. The licensee implements this requirement, in part, through procedure ADM-27.13, which states in part, that tools or materials to remain inside the FME area upon establishing access controls are to be entered on the Access Control Log (Appendix A of ADM-27.13). The procedure also states that when materials and tools are designated as long term, the access control log sheet(s) identifying such materials and tools shall remain an active part of the log.
Contrary to the above, on October 26, 2005, it was determined that the licensee had failed to follow site procedure requirements as stated in licensee procedure ADM-27.13, in that numerous items were left inside the FME area, and were not entered on the access control log sheets.
This violation is associated with an inspection finding that is characterized by the SDP as having very low risk significance (Green) and is in the licensees CAP as CR 2005-28985 and CR 2005-29019. This violation is being treated as a NCV, consistent with Enclosure
Section VI.A of the NRC Enforcement Policy: NCV 50-389/2005-05-03, Loss of FME Integrity When Material Was Found in RCB Which Was Not on the FME Log.
1R22 Surveillance Testing a. Inspection Scope The inspectors witnessed portions of the following six surveillance tests and monitored test personnel conduct and equipment performance, to verify that testing was being accomplished in accordance with applicable operating procedures. The test data was reviewed to verify it met TS, UFSAR, and/or licensee procedure requirements. The inspectors also verified that the testing effectively demonstrated the systems were operationally ready, capable of performing their intended safety functions, and that identified problems were entered into the licensees CAP for resolution. The tests included one inservice test (IST) as follows:
- OP 1-220050A, 1A EDG Periodic Test
- OP 2-0410050, 2A High Pressure and Low Pressure Safety Injection System Functional Tests
- OP 1-0410025, Stroke Testing of the Safety Injection Tank Discharge and SI Loop Check Valves
- OP 2-220050A, 2A EDG Periodic Test
- OSP 1-68.01, Containment integrated leak rate test (ILRT)
b. Findings No findings of significance were identified.
1R23 Temporary Plant Modifications a. Inspection Scope The inspectors continued to periodically screen active TSAs for risk significant systems.
The inspectors examined the TSA listed below, which included a review of the technical evaluation and its associated 10CFR50.59 screening. The TSA was compared against the system design basis documentation to ensure that (1) the modification did not adversely affect operability or availability of other systems; (2) the installation was consistent with applicable modification documents; and (3) did not affect TS or require prior NRC approval. The inspectors also observed accessible equipment related to the TSA to verify configuration control was maintained.
- TSA 2-05-10, Temporary Gage Installation at FT-3341 on Reactor Coolant Pump 2B2 Enclosure
b. Findings No findings of significance were identified.
2. RADIATION SAFETY Occupational Radiation Safety Cornerstone 2OS1 Access Controls To Radiologically Significant Areas Access Controls The inspectors reviewed and evaluated licensee guidance and its implementation for controlling and monitoring worker access to radiologically significant areas and tasks associated with the Unit 1 Refueling Outage Cycle 20 (1 RFO 20). The inspectors evaluated changes to, and adequacy of procedural guidance; directly observed implementation of established administrative and physical radiological controls; appraised radiation worker and technician knowledge of, and proficiency in implementing radiation protection activities; and assessed radiation worker (radworker)
exposures to radiation and radioactive material.
The inspectors directly observed controls established for workers and Health Physics Technician (HPT) staff in potential airborne radioactivity area, radiation area, high radiation area (HRA), locked-high radiation area (LHRA), and very high radiation area (VHRA) locations. Controls and their implementation for LHRA keys and for storage of irradiated material within the U1 spent fuel pool (SFP) were reviewed and discussed in detail. Established radiological controls were evaluated for selected 1 RFO 20 tasks including original reactor vessel closure head (ORVCH) and original pressurizer (OPZR)
replacement and temporary onsite storage; Resistance Temperature Detector (RTD)
modifications; refueling operations; valve maintenance; radioactive waste (radwaste)
processing and storage; and radioactive material/waste shipping activities. In addition, licensee controls for areas where dose rates could change significantly as a result of plant shutdown and refueling operations were reviewed and discussed.
For selected tasks, the inspectors attended pre-job briefings and reviewed RWP details to assess communication of radiological control requirements to workers. Occupational worker adherence to selected RWPs and HPT proficiency in providing job coverage were evaluated through direct observations and interviews with licensee staff.
Electronic dosimeter (ED) alarm set-points and worker stay times were evaluated against applicable radiation survey results. Worker exposure as measured by ED and by licensee evaluations of skin doses resulting from discrete radioactive particle or dispersed skin contamination events during current 1 RFO 20 activities were reviewed and assessed independently. For HRA tasks involving significant dose gradients, e.g.,
RTD modifications and ORVHR activities, the inspectors evaluated the use and placement of whole body and extremity dosimetry to monitor worker exposure.
Postings and physical controls established within the radiologically controlled area (RCA) for access to the U1 reactor containment building (RCB) and the U1 and Unit 2 (U2) reactor auxiliary building (RAB) locations; radioactive waste processing, storage, Enclosure
shipping equipment and locations; and the low level waste sorting and radioactive material storage facilities were evaluated directly during facility tours. The inspectors independently measured radiation dose rates or directly observed conduct of licensee radiation surveys and results for OPRZ and ORVCH equipment and temporary storage general area locations, U1 RTD hot-leg work locations, and radioactive material/waste shipping tasks. Results were compared to current licensee surveys and assessed against established postings and radiation controls. Licensee controls were observed for selected U1 containment, U1 and U2 RAB LHRA and VHRA locations.
The inspectors evaluated implementation and effectiveness of licensee controls for both airborne and external radiation exposure. The inspectors reviewed and discussed selected whole-body count (WBC) analyses conducted between October 1, 2004, and December 1, 2005, to evaluate implementation and effectiveness of personnel monitoring, and administrative and physical controls including air sampling, barrier integrity, engineering controls, and postings for tasks having the potential for individual worker internal exposures to exceed 30 millirem (mrem) Committed Effective Dose Equivalent (CEDE). Effectiveness of external radiation exposure controls were evaluated through review and discussions of individual worker dose as measured by Thermoluminescent Dosimeter (TLD) or ED for calendar year (CY) 2004 and year-to-date 2005, focusing on selected 1 RFO 20 tasks.
Radiation protection activities were evaluated against Updated Final Safety Analysis Report (UFSAR), Technical Specifications (TS), and 10 Code of Federal Regulations (CFR) Parts 19 and 20 requirements. Specific assessment criteria included UFSAR Section 11, Radioactive Waste Management, and Section 12, Radiation Protection; 10 CFR 19.12; 10 CFR 20, Subpart B, Subpart C, Subpart F, Subpart G, Subpart H, and Subpart J; TS Sections 6.8, Procedures, 6.11, Radiation Protection Program, and 6.12, High Radiation Area. Detailed procedural guidance and records reviewed for this inspection area are listed in Sections 2OS1, 2OS2, 2PS2, 4OA1 and 4OA5 of the report Attachment.
Problem Identification and Resolution Licensee Corrective Action Program (CAP)
documents associated with access control to radiologically significant areas were reviewed and assessed. The inspectors evaluated the licensees ability to identify, characterize, prioritize, and resolve the identified issues in accordance with Nuclear Administrative Procedure (NAP) - 204, Condition Reporting, Revision (Rev.) 6.
Licensee CAP documents associated with access control issues, personnel radiation monitoring, and personnel exposure events which were reviewed and evaluated in detail during inspection of this program area are identified in Sections 2OS1, 2OS2, 2PS2, and 4OA1 of the report Attachment.
The inspectors completed 21 of the specified line-item samples detailed in Inspection Procedure (IP) 71121.01.
Enclosure
b. Findings Introduction: A self-revealing, Green NCV of TS 6.11 was identified for failure to implement adequate HP controls for work conducted near contaminated pressurizer components as required by HPP-3, High Radiation Areas, Rev. 17A.
Description: On November 25, 2005, two individuals entered the U1 pressurizer cubicle to perform a visual inspection of valve V1249 internal components. The work location was controlled as a HRA since general area dose rates were greater than (>)100 millirem per hour (mrem/hr) and the interior of V1249 was highly contaminated with levels of removable contamination on the order of 1 rad beta per hour (rad -/hr) per 100 square centimeters (100 cm2). The workers were logged in on RWP No.05-710, which required the use of power visors and paper coveralls, in addition to normal Protective Clothing (PC), to reduce the risk of contamination. Contrary to the established RWP requirements, the workers entered the work area in single PCs and without power visors. Although constant HP coverage was required and HPTs have the responsibility to stop work when RWP requirements are not adhered to, the technician providing job support allowed the workers to breach the valve cover and begin their inspection without the proper PCs. The inspection was stopped by the workers a short time later due to Foreign Material Exclusion (FME) concerns regarding sparks from nearby welding activities. Both workers subsequently alarmed personnel contamination monitors at the RCA exit point and were sent for investigational whole body counts. It was determined that both workers had facial contamination along with positive intakes of radioactive material.
Analysis: The inspectors determined that the licensees failure to implement adequate HP controls for a HRA is a performance deficiency because the licensee is required by TS 6.11 to maintain and implement procedures for radiation protection and the incident was reasonably within the licensees ability to foresee and correct. This finding is greater than minor because it is associated with the Occupational Radiation Safety Cornerstone attribute of exposure/contamination control and adversely affects the cornerstone objective of ensuring adequate protection of worker health and safety from exposure to radiation from radioactive material during routine civilian nuclear reactor operation. The failure to follow established RWP requirements and to provide adequate HPT coverage for the workers in HRAs or highly contaminated areas could result in unintended occupational exposures. The finding was evaluated using the Occupational Radiation Safety SDP. The finding was not related to ALARA planning, nor did it involve an overexposure or substantial potential for overexposure, and the ability to assess dose was not compromised. For these reasons, and the fact that intakes of radioactive material were low, the SDP evaluation concluded that the finding was of very low safety significance (Green). The finding involved the cross-cutting aspect of Human Performance because the contamination events were a direct result of worker and HP technician failure to follow RWP and procedural requirements.
Enforcement: TS 6.11 requires the licensee to establish, implement, and maintain the procedures for personnel radiation protection consistent with the requirements of 10 CFR 20. Licensee procedure HPP-3, High Radiation Areas, states that individuals working in HRAs shall adhere to RWP requirements and that HP technicians providing Enclosure
job coverage shall be knowledgeable of those requirements and will maintain control over workers in the area. Contrary to the above, on November 25, 2005, two workers entered a HRA without RWP required protective gear and a HP technician failed to exercise control over the work activities. Because the failure to comply with TS 6.11 is of very low safety significance and has been entered into the licensees CAP (CR 2005-32859), this violation is being treated as an NCV, consistent with Section VI.A of the NRC Enforcement Policy: NCV 05000335/389, 2005005-04, Failure to Implement Required HP Controls for U1 Pressurizer Valve Work.
2OS2 ALARA Planning and Controls a. Inspection Scope As Low As Reasonably Achievable (ALARA) The inspectors reviewed ALARA program guidance and its implementation for ongoing 1 RFO 20 tasks. The inspectors evaluated the accuracy of ALARA work planning and dose budgeting, observed implementation of ALARA initiatives and radiation controls for selected jobs in-progress, assessed the effectiveness of source-term reduction efforts, and reviewed historical dose information.
ALARA planning documents and procedural guidance were reviewed and projected dose estimates were compared to actual dose expenditures for OPZR and ORVCH replacement, RTD maintenance activities, and refueling operations. Differences between budgeted dose and actual exposure received were discussed with cognizant ALARA staff. Changes to dose budgets relative to changes in radiation source term and/or job scope were also discussed. The inspectors attended pre-job briefings and evaluated the communication of ALARA goals, RWP requirements, and industry lessons-learned to job crew personnel. The inspectors also attended a Plant ALARA Review Committee meeting and observed the interface between plant management and ALARA planning staff.
The inspectors made direct field or closed-circuit-video observations of outage job tasks including OPZR and ORVCH replacement activities. For the selected tasks, the inspectors evaluated radworker and HPT job performance; individual and collective dose expenditure versus percentage of job completion; surveys of the work areas, appropriateness of RWP requirements; and adequacy of implemented engineering controls. For selected tasks, the inspectors interviewed radworkers and job sponsors regarding understanding of dose reduction initiatives and their current and expected accumulated doses at completion of the job tasks.
Implementation and effectiveness of selected program initiatives with respect to source-term reduction were evaluated. Chemistry program ALARA initiatives and their effect on U1 RCB and U1/U2 RAB dose rate trends were reviewed. The effectiveness of temporary shielding installed for the current outage was assessed through review of shielding request packages and pre-shielding versus post-shielding dose rate data. The inspectors also reviewed results of pipe flushing to reduce dose rates associated with OPZR activities.

b. Findings:
Introduction: A Green NRC-identified NCV of 10 CFR 71.5 was identified for failure to implement current package design specifications for proper closing of Type A shipping packages as required by DOT regulations. Specifically, for Type A packages containing in-core instrument cutting equipment shipped on October 3, 2003, and February 17, 2005, the licensee failed to close the package in accordance with vendor specifications as required by 49 CFR 173.475(e).
Description: The inspectors determined that the licensee did not possess all of the package preparation instructions referenced within the container certification for use in preparation of a DOT Type A package (Model SSB-18-1-7A-TRF). The Type A package was used for shipment of in-core instrument cutting equipment to other licensed facilities offsite. Subsequent calls to the vendor supplying the Type A packages resulted in receipt of current and accurate package certification and engineering evaluation documentation. The inspectors noted that the documents provided specifications for lid closure device (T-bolt) torque values, bolt closure sequence, and seal gasket inspection procedures. From review and discussion of shipping records associated with previous Type A package shipments made on October 3, 2003 and February 17, 2005, the inspectors noted that required lid closure device torque values and assembly configurations were not specified. Licensee representatives stated that previous package preparation guidance did not specify a required closure torque value nor a closure device configuration, but only required the verification that the T-bolts and lid were secured tightly.
Analysis: The licensees failure to satisfy 10 CFR 71.5 which requires compliance with 49 CFR Part 173 for DOT Type A package vendor engineering analysis specifications is a performance deficiency. Specifically, users of Type A packages are expected to maintain and implement current package engineering analysis closure specifications.
The finding was more than minor because it is associated with the public radiation cornerstone program and process attribute and it affected the cornerstone objective to ensure adequate protection of public health and safety from exposure to radioactive material released into the public domain. This finding resulted in the transportation of Type A packages that had not been properly secured for shipment as required by DOT regulations. The issue was reviewed using the Public Radiation Safety Significance Determination Process and was determined to be of very low safety significance (Green) because it did not involve a radiation limit being exceeded nor packaging being breached. The licensee initiated immediate corrective actions to assure that future Type A packages are prepared properly prior to shipment. This finding involved the cross-cutting aspect of problem identification and resolution because missed lid bolting torque for a Type A package was discussed in OE 19531, however, the licensee failed to enter this OE into their CAP and ensure its implementation into their transportation program activities.
Enclosure
Enforcement: 10 CFR 71.5 requires licensees to conform with the regulations in DOT 49 CFR Parts 170 through 189. For Type A package shipments, 49 CFR 173.415(a)
requires each offeror of a Specification 7A Type A Package to maintain on file for at least one year after the latest shipment, complete documentation of tests and engineering evaluation or comparative data showing the construction methods, packaging design and materials of construction to comply with that specification.
Further, 49 CFR 173.475(e) requires that each special instruction for closing and preparation of a package be followed. For shipments of Type A packages made on October 3, 2003, and February 17, 2005, the licensee failed to implement current design document specifications for closure of the DOT Type 7A packages, in that, T-bolt torque values and closure assembly specifications for package closure were not met. The licensee documented this issue in its CAP as CR No. 2005-25727. Since this violation is of very low safety significance and the licensee entered the finding into its CAP, this violation is being treated as a NCV consistent with Section VI.A of the NRC Enforcement Policy: NCV 05000335, 389/2005005-05, Failure to Implement Appropriate DOT Type A Package Closure Requirements.
4. OTHER ACTIVITIES 4OA1 Performance Indicator Verification a. Inspection Scope The inspectors sampled licensee data for the performance indicators (PIs) listed below.
To verify the accuracy of the reported PI data, PI definitions and guidance contained in NEI 99-02, "Regulatory Assessment Indicator Guideline," Rev. 3, were used to screen each data element.
Public Radiation Safety Cornerstone The inspectors reviewed the Radiological Control Effluent Release Occurrences PI results from October 2004, through September 2005.
For the assessment period, the inspectors reviewed cumulative and projected doses to the public, out-of-service (OOS) effluent radiation monitors and selected compensatory sampling data, and CRs related to RETS/ODCM issues. The inspectors also reviewed licensee procedural guidance for collecting and documenting PI data. Documents reviewed are listed in Section 4OA1 of the report Attachment.
Occupational Radiation Safety Cornerstone The inspectors reviewed the Occupational Exposure Control Effectiveness PI results from October 2004 through September 2005.
For the assessment period, the inspectors reviewed electronic dosimeter alarm logs and CRs related to controls for exposure significant areas. The inspectors also reviewed licensee procedural guidance for collecting and documenting PI data. Report Section 2OS1 contains additional details regarding the inspection of controls for exposure significant areas. Documents reviewed are listed in Sections 2OS1 and 4OA1 of the report Attachment.
The inspectors completed the two specified radiation protection line-item samples detailed in IP 71151.
Enclosure
b. Findings No findings of significance were identified.
4OA2 Identification and Resolution of Problems 1. Review of Items Entered into the Corrective Action Program a. Inspection Scope As required by Inspection Procedure 71152, Identification and Resolution of Problems, and in order to help identify repetitive equipment failures or specific human performance issues for followup, the inspectors performed screening of all items entered into the licensees CAP. This was accomplished by reviewing the description of each new CR and periodically attending CR oversight group meetings.
2. Semi Annual Review to Identify Trends a. Inspection Scope As required by Inspection Procedure 71152, Identification and Resolution of Problems, the inspectors performed a review of the licensees CAP and associated documents to identify trends that could indicate the existence of a more significant safety issue. The inspectors review included daily screening of individual CRs, licensee trending efforts, and licensee human performance self-assessments. The inspectors review nominally considered the six month period of July 2005 through December 2005. Furthermore, the inspectors verified whether adverse or negative trends and issues identified in the licensees reports were entered into the CAP.
b. Assessment and Observations During the past six months, the inspectors identified two issues and the licensee identified one issue related to plant configuration control through the use of the licensees TSA process. The licensees guidance for implementing a temporary design change to the plant is through administrative procedure ADM-17.18, Temporary System Alteration, which states that the purpose of a TSA is to maintain configuration control for non-permanent changes to plant SSCs while ensuring the applicable technical and administrative reviews and approvals are obtained. The inspectors had previously identified two plant modifications that the licensee did not control by the use of their TSA procedure including both a structural floor drain modification and an electrical control rod assembly position indication modification as documented in St. Lucie Plant Inspection Reports 2005-03 and 2005-04 respectively. In addition, the licensee identified a refueling water tank structural modification which was also implemented outside the TSA process during SL1-20 and entered it into their CAP as CR 2005-27368. The licensee considered these findings as a possible trend and tasked their system engineering department to perform reviews of their assigned SSCs to ensure current as-is configuration was in accordance with their docketed design bases. The results of the Enclosure
system engineering review did not identify any additional significant configuration control deficiencies.
The licensee subsequently trained their engineering staff on the usage of the TSA process and discussed recent findings related to not using the required TSA procedure.
The licensee is evaluating a possible revision to their TSA procedure to clearly define what a TSA consists of and expectations on when and how to implement the TSA process. The inspectors considered the licensees actions to be adequate in minimizing the recurrence of TSA misuse in the future.
.3 Annual Sample: Review of Hot Work Fire Prevention Controls a. Inspection Scope The inspectors reviewed licensee actions to resolve a trend in small fires resulting from hot work activities inside the Unit 1 RCB. The inspectors reviewed how the licensee performed hot work activities including planning, scheduling, and controlling evolutions that could produce sparks, slag, or other fire ignition sources. During the recent Unit 1 RFO, the licensee performed numerous metal cutting and arc-gouging operations associated with the planned pressurizer and reactor vessel head replacement modifications.
b. Findings and Observations Introduction: The inspectors identified a Green NCV during a trend review of several small fire events which occurred over several weeks in the Unit 1 RCB during outage hot work (air arc gouging) activities. The inspectors determined that the licensee failed to take timely and effective corrective actions to prevent recurrence of fires started from hot work activities.
Description: On October 28, 2005, during arc-gouging metal removal activities on the reactor coolant loop A hot leg whip restraint, a small fire occurred on the fire blanket used to deflect and or capture hot slag. The fire watch immediately responded to the source of the fire and extinguished it with the use of a dry chemical type extinguisher.
The licensee recommended actions to prevent recurrence included the availability of a garden sprayer to maintain the fire blanket wet at all times. On November 1, 2005, another fire occurred during hot work to remove a whip restraint on the B steam generator hot leg nozzle. The fire ignited a 4-inch diameter flexible duct used as an exhaust path to a HEPA filter intended to remove smoke and fumes from the work area.
Although personnel in the work area extinguished the fire within two minutes, the containment atmosphere became slightly smoke filled and the containment was evacuated.
The licensee performed a root cause analysis following the flexible duct fire. Interim corrective actions included: directions for ensuring the placement of flexible ducts such that they are above the hot work or between the hot work and the worker, and far enough away that slag does not reach the duct opening; protecting HEPA flexible ducts with fire retardant material when run near or below hot work; and, including an Enclosure
information package with all hot work pre-job briefs regarding preliminary available information regarding this event. The corrective actions resulting from the licensees root cause investigation was to revise procedure AP 0010434, Plant Fire Protection Guidelines, to include information on the appropriate use of flexible ducts or ventilation equipment; revise hot work permit forms to include a check box to review the ventilation equipment precautions prior to permit approval; and revise the hot work permit form to include criteria that will prompt a review/approval section by the fire protection engineer or outage/work control center.
On November 8, 2005, while performing air arc gouging on the containment hatch transfer system (HTS), a crane signalmans vest lying in the area, ignited from slag generated from this work. The deck of the HTS had been covered by fire blankets in preparation for this work but in the process of personnel and equipment movement on the deck, the vest became uncovered by the fire blankets and ignited. The fire watch immediately spotted the fire and put it out with a fire extinguisher. This event was evaluated as part of the root cause analysis for the fire that previously occurred on November 1.
On November 18, 2005, air arc gouging was being performed on the annulus side of the containment construction hatch when hot slag came into contact with and ignited an air line that was being used for the arc-gouging process. Additionally, on November 20, 2005, the smell of smoke was reported from individuals working above the 62-foot elevation inside the pressurizer cubicle. Subsequent investigation by the licensee found an empty smoldering bolt bag near the base of the pressurizer skirt that was promptly extinguished and removed from the area. Apparently the bag had been inadvertently placed in an area being controlled as a hot work area. Apparent cause evaluations were performed by the licensee for these two fires with the results being a combination of inadequate situational assessment, unusual or hazardous conditions not being defined, and poor housekeeping. Resultant licensee corrective actions were to ensure site wide dissemination of these recent fire events.
Analysis: The inspectors determined that multiple fires inside containment caused by hot work activities was a performance deficiency requiring a significance evaluation in accordance with IMC 0612, Power Reactor Inspection Reports, Appendix B, Issue Screening. The inspectors determined that the finding was more than minor because it was associated with the protection against external factors attribute of the Initiating Events cornerstone and adversely impacted the cornerstone objective of limiting the likelihood of those events that upset plant stability and challenge critical safety functions during shutdown operations. In addition, if left uncorrected, this finding could result in a more significant safety concern. Specifically, one of the key attributes associated with this cornerstone objective is protection against fires, and the inspectors determined that the licensees failure to take timely and effective corrective actions with respect to hot work ignition control deficiencies was a performance deficiency. The cause of the finding is related to the cross-cutting element of problem identification and resolution, specifically involving incomplete corrective actions.
Enclosure
The inspectors conducted a Phase 1 initial screening in accordance with IMC 0609, Significance Determination Process, and because the finding was associated with fire protection, this was accomplished using IMC 0609, Appendix F, Attachment 1, Fire Protection SDP Phase 1 Worksheet. The inspectors determined that the finding was associated with fire prevention and administrative controls and assigned a low degradation rating. As a result of the Phase 1 screening, this finding was determined to be of very low safety significance (Green).
Enforcement: TS 6.8.1.f, states, in part, that procedures shall be established, implemented, and maintained covering Fire Protection Program implementation. The St. Lucie Fire Protection Plan, as delineated in Administrative Procedure 1800022, refers in Section 8.10 to FPLs Topical Quality Assurance Report (TQAR) for requirements on corrective actions related to Fire Protection. Section 16.1 of the TQAR, states, in part, that for conditions adverse to quality, the cause of the condition shall be determined and action taken to preclude repetition. Contrary to this requirement, the licensee failed to take timely and adequate corrective actions for deficiencies relating to hot work ignition source controls in the Unit 1 RCB. Specifically, multiple fires occurred in the Unit 1 containment caused, in part, by deficiencies related to hot work ignition source control during arc-gouging activities.
The licensee entered the issue into their CAP as CR 2005-33661. This CR requires a comprehensive common cause analysis by a cross-functional team, which will examine the various fire protection issues identified to determine whether or not a generic fire protection programmatic weakness is present. Because the licensee has entered the issue into their CAP and the finding is of very low safety significance (Green), this violation of TS 6.8.1, is being treated as an NCV, consistent with Section VI.A of the NRC Enforcement Policy: NCV 05000335/2005005-06: Failure to Take Adequate Corrective Actions for Deficiencies Relating to Hot Work Ignition Source Controls in the Unit 1 RCB.
4OA3 Event Followup
.1 (Closed) Licensee Event Report (LER) 05000335/2005001, Condition Prohibited by TS Due to Inoperable Reactor Protection Instrumentation Channel and Engineered Safety Feature Actuation System (ESFAS) Instrumentation Channel On February 19, 2005, while Unit 1 was operating at full power, the licensee identified a 3 to 4 percent high deviation between 1B steam generator narrow range water level indicator, LIC-9023A, and its three redundant level channels. The cause of this high deviation was determined to be a packing leak on an instrument isolation valve in the upper sensing line attached to the condensing pot. The instrument valve packing leakage exceeded the condensing pots makeup capability and voided a portion of the reference leg. The lowered reference leg water level caused LIC-9023A to indicate a higher than actual steam generator water level. A subsequent engineering evaluation concluded that steam generator water level channel indication deviations greater than 2 percent render the channel inoperable. Consequently, the channel was declared OOS on March 22, 2005. Per TS 3.3.1 and 3.3.2 the inoperable Reactor Protective System Instrumentation and ESFAS Instrumentation channels were placed in the tripped Enclosure
condition within one hour. No new findings were identified in the inspectors review.
This finding constitutes a violation of minor significance that is not subject to enforcement action in accordance with Section IV of the NRCs Enforcement Policy.
The licensee documented the problem in CR 2005-8049. This LER is closed.
.2 (Closed) Licensee Event Report (LER) 05000335/2005003, 1A EDG Actuation On May 18, 2005, the 1A EDG auto started during scheduled emergency electrical bus undervoltage testing due to a test circuit control logic relay design condition which could allow the operation of a test switch to cause an actual 4160 Volt feeder breaker to open unexpectedly. Turning the test switch to the test position prevents an actual load shed by bypassing the undervoltage trip actuating relay contacts and connects them to the test lamp circuit. The most probable cause was determined to be a design weakness allowing an electrical race between test switch CS-9/949 and relay 27X-9/1A3 when the test switch is operated from the RELAY TEST to the OFF position in a rapid manner. A key contributing cause was that the procedure did not require slow operation of the switch. The licensee documented the condition in CR 2005-14777. The LER was reviewed and no findings of significance were identified. No violation of NRC requirements occurred. This LER is closed.
.3 (Closed) Licensee Event Report (LER) 05000389/2004004, Manual Reactor Trip Due to Condensate Pump Motor Malfunction On December 25, 2004, the operators manually tripped the Unit 2 reactor after high temperatures were observed locally at the 2B condensate pump motor. The cause of the high temperature was subsequently identified as a motor overcurrent condition caused by an incorrect motor lug assembly process performed by the manufacturer.
The licensee corrected the condition and planned inspections of other large risk significant motors for potential similar assembly deficiencies in order to evaluate the extent of the condition. The LER was reviewed and no findings of significance were identified. No violation of NRC requirements occurred. This LER is closed.

.5 Concrete Shield Building Restoration Activities (IP 50003)
a. Inspection Scope The inspectors examined restoration activities associated with the temporary construction opening (approximately 29 feet in diameter) in the Unit 1 concrete containment shield building wall, as detailed in the licensees Plant Change/Modification (PC/M) Package 04-134M, Rev. 1, Removal and Restoration of Shield Building Concrete Construction Hatch for Unit 1 RVCH/PZR Replacement Project.
Relative to installation of concrete for the Unit 1 containment repair, the inspectors reviewed the commercial grade dedication plan for the concrete mix. The inspectors also reviewed vendor surveillance reports covering the licensees inspection of the concrete batch plant and the concrete truck mixers to verify the trucks and batch plant complied with the guidance of the National Ready Mixed Concrete Association (NRMCA); that the batch plant scales were calibrated in accordance with NRMCA recommendations; and mixer efficiency tests were performed on the truck mixers in accordance with ASTM C-94. In addition, the inspectors reviewed the results of acceptance testing performed on materials (cement, fine and coarse aggregate, water, and admixtures) used for batching the concrete and records documenting post-placement inspection of concrete curing. The inspectors reviewed the concrete mix data to ensure that mix proportions for delivered concrete were selected based on trial concrete mix results, that QC acceptance criteria for the plastic concrete were based on the trail mixes, and that the trail mix met concrete strength requirements. Other records reviewed documented the results of in process tests performed on the plastic concrete (slump, entrained air, temperature, and unit weight), and results of unconfined compression tests performed on concrete test cylinders to verify concrete met design strength requirements.
b. Findings No findings of significance were identified.
.6 Review of 10 CFR 50.59 Screening/Evaluation for the Replacement RPVH a. Inspection Scope The inspectors reviewed PCM-04129, RVCH Replacement Modification for Unit 1 RVCH Replacement Project, including the associated 10 CFR 50.59 screening to verify that changes between the original RPVH and the replacement RPVH, and modifications resulting from installation of the replacement RPVH were properly evaluated in accordance with 10 CFR 50.59. The inspectors review included verification that the weight of the replacement RPVH, and its effect on reactor vessel supports and polar crane load capacity was taken in consideration as part of the design change.
Enclosure
b. Findings No findings of significance were identified.
.7 Review of Quality Assurance (QA) Activities for the fabrication of the RPVH a. Inspection Scope The inspectors reviewed documentation to verify that the licensee implemented an adequate QA oversight of the manufacturer activities (Areva, France). The inspectors reviewed a sample of surveillance reports prepared by licensees QA personnel at the vendor facilities, which covered three months of surveillance activities during the fabrication of the RPVH. The inspectors reviewed the activities indicated in the report and verified their adequacy.
In addition, the inspectors reviewed an audit conducted by the licensee as part of the Nuclear Procurement Issues Committee (NUPIC), which took place at two manufacturers facilities and evaluated the adequacy of the manufactures QA program in the following areas: Order Entry, Design, Software QA, Procurement, Fabrication and Assembly, Material Control, Handling, Storage and Shipping, Special Processes, Tests and Inspections, Calibration, Document Control, Organization and Program, Nonconforming Items/Part 21, Internal Audits, Corrective Action, and Training/Certification and Records. The inspectors reviewed the thoroughness of the audit and the impact of audit findings on the fabrication of the RPVH.
b. Findings No findings of significance were identified.
.8 Reactor Vessel Head Replacement Radiation Protection Inspection a. Inspection Scope The inspectors reviewed and evaluated planning and implementation of radiological controls for ORVCH replacement activities.
Radiation, contamination, and airborne radioactivity surveys were reviewed for radiological work conditions and the adequacy of prescribed postings and HP controls.
The inspectors reviewed RWPs and evaluated ED alarm settings, worker and HPT instructions, special dosimetry needs, and protective clothing/equipment requirements.
ALARA planning, dose reduction initiatives, and actual doses received were reviewed and discussed with the RVCH replacement project and ALARA staff. The inspectors also reviewed plans for temporary storage of vessel head. A review of the training provided to workers is detailed in section 2PS2. Individual worker doses and project dose expenditures for the U1 ORVCH disassembly, removal from containment, packaging, and staging at the onsite temporary storage location were reviewed and discussed in detail with licensee representatives.
Enclosure
Radiological controls associated with the ORVCH prior to its removal from containment and subsequent to its placement in the onsite temporary storage facility were observed and evaluated. The inspectors observed implementation of radiological controls including posting, shielding, and air monitoring around the old ORVCH and selected components in containment. The inspectors also toured the onsite temporary storage facility and conducted independent surveys of the temporary storage environs and reviewed radiological controls and applicable environmental monitoring programs.
Packaging used to ship the ORVCH was reviewed and plans for shipment of the ORVCH to a radwaste processing vendor were discussed with licensee staff.
RVCH replacement activities were evaluated against 10 CFR Parts 19 and 20, and approved licensee procedures. Licensee guidance documents, records, and data reviewed within this inspection area are listed in Sections 2OS1 and 2PS2 of the report Attachment.
The inspectors completed the specified radiation protection line-item samples detailed in IP 71007.
b. Findings No findings of significance were identified.
.9 (Closed) Temporary Instruction (TI) 2515/161, Transport of Control Rod Drive (CRD) in Type A Packages a. Inspection Scope The inspectors reviewed shipping logs and discussed shipment of CRDs in Type A packages with shipping staff. The inspectors noted that no shipments of CRDs in Type A packages have been made since January 1, 2002. The only recent uses of a Type A package, i.e., shipments of in-core instrument cutting equipment, were reviewed and evaluated as part of routine inspection activities documented in Section 2PS2 of this report. The inspectors completed all the relevant inspection activities detailed in TI 2515/161.
b. Findings No findings of significance were identified.
4OA6 Meetings Exit Meeting Summary On January 4, 2006, the resident inspectors presented the inspection results to Mr. Bill Jefferson and other members of his staff, who acknowledged the findings. The inspectors asked the licensee whether any of the material examined during the inspection should be considered proprietary. No proprietary information was identified.
Enclosure
Interim Exit Meetings Interim exit meetings were conducted for:
- IP 50003 - Welding of SCV Construction Hatch on November 22, 2005, and Lifting and Transportation Program and Design Review of Activities Associated With the Pressurizer Replacement on December 2, 2005. The licensee confirmed that none of the potential report input discussed was considered proprietary.
- Baseline procedure 71111.08 on November 4, 2005. The licensee confirmed that none of the potential report input discussed was considered proprietary.
4OA7 Licensee Identified Violations The following violations of very low safety significance (Green) were identified by the licensee and are violations of NRC requirements which meet the criteria of Section VI of the NRC Enforcement Policy, NUREG-1600, for being dispostioned as NCVs.
- Technical Specification 3.3.1.1 and 3.3.2.1 requires that reactor protective system instrumentation channels be placed in trip if not operable within one hour.
Contrary to this, steam generator water level instrument LIC-9023A was inoperable on February 19, 2005, and was not placed in the bypassed or tripped condition until March 22, 2005. This issue has been captured by the licensees CAP as CR 2005-8049. The finding is of very low safety significance because it does not represent an actual loss of a safety function.
- 10 CFR Part 20.1902(b) requires each HRA to be conspicuously posted Caution, High Radiation Area or Danger, High Radiation Area. Contrary to the above, from November 18, through November 20, 2005, the U1 Volume Control Tank (VCT) cubicle was not posted as a HRA even though general area dose rates exceeding 100 mrem in one hour existed in the area. Specifically, at 19:20 hours (hrs) on November 18, an HPT down-posted the VCT cubicle from an HRA to a radiation area based on limited surveys. At 22:00 hrs on November 20, an HPT conducting routine pre-job surveys in the VCT cubicle identified the posting discrepancy and took immediate corrective actions. Licensee personnel entered and worked in the VCT cubicle while the area was posted improperly.
This event is documented in the licensees CAP as CR 2005-32778. Although this event involved failure to maintain proper controls for an HRA, this finding is of very low safety significance because workers in the VCT cubicle were on appropriate RWPs, had proper dosimetry, and no unexpected/ unintended radiation exposures occurred.
