SUBJECT:

ST. LUCIE NUCLEAR PLANT - NRC INTEGRATED INSPECTION REPORT 05000335/2005003 AND 05000389/2005003 AND EXERCISE OF ENFORCEMENT DISCRETION

Dear Mr. Stall:

On June 30, 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 July 5, 2005, 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.

The report closes one issue involving a failure to protect cables from fire damage, which could result in a number of valves spuriously operating in a manner, which could adversely affect safe shutdown capability. Although the issue constitutes a violation of NRC requirements, the NRC is exercising enforcement discretion and reactor oversight process discretion (i.e. not subjecting the violation to the significance determination process (SDP)). The basis for the enforcement discretion is NRC Enforcement Manual Section 8.1.7.1 ©), Fire Induced Circuit Failures. One of the conditions for applying discretion is that the circuit vulnerabilities be corrected within a reasonable time frame. NRC Inspection Manual Chapter 0305, Operating Reactor Assessment Program, Section 06.06.2, Violations in Specified Areas of Interest Qualifying for Enforcement Discretion, states that violations related to certain circuit issues, which are eligible for enforcement discretion shall also be eligible for reactor oversight process discretion. The conditions for applying discretion were met because you did not dispute the violation, entered it into corrective action program and are taking timely corrective action.

In addition, this report documents one inspector identified finding of very low safety significance (Green). This finding was determined to involve a violation of NRC requirements. However, because of the very low safety significance and because it was entered into your corrective action program, the NRC is treating this violation as a non-cited violation (NCV), in accordance with Section VI.A of the NRCs Enforcement Policy. If you contest this NCV, you should provide a response within 30 days of the date of this inspection report, with the basis for your denial, to

FPL 2 the Nuclear Regulatory Commission, ATTN: Document Control Desk, Washington DC 20555-0001; with copies to the Regional Administrator, Region II; the Director, Office of Enforcement, United States Nuclear Regulatory Commission, Washington, DC 20555-0001; and the NRC Senior Resident Inspector at the 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 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 05000335/2005-03, 05000389/2005-03; 04/01/2005 - 06/30/2005; St. Lucie Nuclear Plant, Units 1 & 2; Temporary Plant Modifications.

The report covered a three month period of inspection by resident inspectors and several other inspectors from Region II. One Green non-cited violation (NCV) was 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: Containment Barriers

The finding is greater than minor because it is associated with the plant modification design control attribute of the reactor safety barrier integrity cornerstone and affected the cornerstone objective of ensuring the reliability and capability of the control room emergency ventilation system. The finding was of very low safety significance in accordance with NRC Inspection Manual Chapter 0609, Appendix A, Attachment 1, the SDP Phase 1 screening worksheet because it only represented a degradation of the radiological barrier function provided for the control room. Until the issue could be permanently resolved, the licensee initiated a clearance order to control the system alterations. (Section 1R23)

B. Licensee-Identified Violations None.

Report Details Summary of Plant Status Units 1 and 2 began the report period at 100% power and operated continuously at full power throughout the report period except for short periods of time while conducting planned turbine valve testing.

1. REACTOR SAFETY Cornerstones: Initiating Events, Mitigating Systems, and Barrier Integrity 1R01 Adverse Weather Protection a. Inspection Scope During the week of June 13 and 20, the inspectors reviewed and verified the status of licensee actions taken in accordance with their procedural requirements prior to the onset of hurricane season. The inspectors reviewed lessons learned and corrective actions taken from the 2004 season documented in condition reports 2004-7844 and 2004-9179. The inspectors reviewed Administrative procedure ADM-04.01, Hurricane Season Preparation, Revision 12 and performed site walkdowns 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:

  • Unit 1 and 2 Turbine Buildings
  • Unit 1 and 2 Reactor Auxiliary Buildings b. Findings No findings of significance were identified.

1R02 Evaluations of Changes, Tests or Experiments a. Inspection Scope The inspectors reviewed selected samples of evaluations to confirm that the licensee had appropriately considered the conditions under which changes to the facility, Updated Final Safety Analysis Report (UFSAR), or procedures, may be made, and tests conducted, without prior NRC approval. The inspectors reviewed evaluations for seven changes and additional information, such as calculations, supporting analyses, the UFSAR, and drawings to confirm that the licensee had appropriately concluded that the changes could be accomplished without obtaining a license amendment. The seven evaluations reviewed are listed in the List of Documents Reviewed.

The inspectors also reviewed samples of changes for which the licensee had determined that evaluations were not required, to confirm that the licensees conclusions to screen out these changes were correct and consistent with 10CFR50.59. The twenty-two screened out changes reviewed are listed in the List of Documents Reviewed.

Enclosure

The inspectors also reviewed corrective action report forms (condition reports) (CR) to confirm that problems were identified at an appropriate threshold, were entered into the corrective action process, and appropriate corrective actions had been initiated.

During this simulator evaluation, the inspector witnessed the operating crew perform a reactor power ascension sequence, which included transition from manual to automatic steam generator water level control, loading the main turbine generator, and increasing reactor power level. The inspector specifically evaluated the following attributes related to the operating crews performance:
  • Clarity and formality of communication
  • Prioritization, interpretation, and verification of alarms
  • Correct use and implementation of Normal Operating Procedures
  • Control board operation and manipulation, including high-risk operator actions
  • Oversight and direction provided by operations supervision, including ability to identify and implement appropriate TS actions
  • Effectiveness of the post-evaluation critique b. Findings No findings of significance were identified.

1R12 Maintenance Effectiveness a. Inspection Scope The inspectors reviewed the reliability and deficiencies associated with the two systems listed below, including associated condition reports. The inspectors verified the licensees maintenance effectiveness efforts met the requirements of 10 CFR 50.65 and Administrative Procedure ADM-17.08, Implementation of 10 CFR 50.65, The Enclosure

Maintenance Rule. The inspectors focused on the licensees system functional failure determination, a(1) and a(2) classification determination, corrective actions, and the appropriateness of established performance goals and monitoring criteria. The inspectors also attended applicable expert panel meetings, and interviewed responsible engineers. The inspectors reviewed associated system health reports, system walkdown reports, and the licensees goal setting and monitoring requirements.

  • Unit 2 Control Element Drive System
  • Unit 1 Containment Spray System b. Findings No findings of significance were identified.

1R13 Maintenance Risk Assessments and Emergent Work Evaluation a. Inspection Scope The inspectors reviewed the risk assessments for the following six Systems, Structures, or Components (SSC) or a combination thereof that were non-functional due to planned and/or emergent work. The inspectors also walked down and/or reviewed the scope of work to evaluate the effectiveness of licensee scheduling, configuration control, and management of online risk in accordance with 10 CFR 50.65(a)(4) and applicable program procedure ADM-17.16, Implementation of the Configuration Risk Management Program.

  • CR 2005-17843, Unit 2 Degraded Engineered Safety Feature Actuation System Relay Socket Connection b. Findings No findings of significance were identified.

1R16 Operator Workarounds a. Inspection Scope The inspectors reviewed unit 2 operator workaround OWA 2-155 associated with a manual action requirement to isolate warm up steam from steam generator B to the 2C auxiliary feedwater pump turbine in the event of a faulted steam generator. Warm up steam solenoid valve SE-08-1 leaks by its seat when in the closed position. In the event of a faulted steam generator, the operator must manually close stop valve VO8883 to isolate warm up steam flow to the turbine. The inspectors verified the OWA did not affect either the functional capability of the related system in responding to an initiating event or the operators ability to implement abnormal or emergency operating procedures.

b. Findings No findings of significance were identified.

1R17 Permanent Plant Modifications a. Inspection Scope The inspectors evaluated design change packages for nine modifications, in the Initiating Events, Mitigating Systems, and Barrier Integrity cornerstone areas, to Enclosure

The tests included one inservice test (IST), and one RCS leak detection TS surveillance test as follows:

Enclosure

  • 1-INP-26.14, Containment Atmosphere Process Monitor Functional Test
  • OP 0-3200051, Unit 2 Moderator Temperature Coefficient Periodic Test
  • OP 1-0010125A, Degraded Grid Voltage Functional Test b. Findings No findings of significance were identified.

1R23 Temporary Plant Modifications a. Inspection Scope The inspectors continued to periodically screen active temporary system alterations (TSA) for risk significant systems. The inspectors examined the two TSAs listed below, which included a review of the technical evaluation and its associated 10CFR50.59 screening. In addition, the inspectors reviewed the temporary metal plates in the north and south CREVS fan room floor drains installed to help improve the required control room positive differential pressure to verify they were implemented in accordance with TSA process. The temporary alteration 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 temporary modification to verify configuration control was maintained.

  • TSA 05-004, Unit 2 480 Volt Pressurizer Heaters b. Findings Introduction. A Green non-cited violation (NCV) was identified for failing to implement administrative procedure ADM-17.18, Temporary System Alteration, Revision 6, as prescribed by TS 6.8.1.a and Regulatory Guide 1.33.

Description. On October 19, 2001, the licensee experienced difficulty maintaining a positive differential pressure (dP) of greater than or equal to 0.125 inches of water when performing surveillance test procedure 2-OSP-25.01, Control Room Pressure Periodic Test and documented the issue in CR 2001-2528. An evaluation by the licensee concluded that the floor drains in the fan room were interconnected with other rooms in the reactor auxiliary building, which affected the ventilation systems ability to maintain the required positive differential pressure. Subsequently, on October 26, 2001, the licensee installed temporary metal plates in the north and south CREVS fan room floor drains under work order number 31019445 to help improve the required control room Enclosure

positive differential pressure. After the plates were installed the surveillance was re-performed successfully.

On May 10, 2005, while conducting a fire protection walkdown, the inspectors identified the two floor drains in the unit 2 CREVS fan room, which were covered with sheet metal and sealed with caulking below the floor grating. The inspectors questioned the licensee regarding the analysis that was performed to approve the installation as well as the adequacy of the material used. The inspectors determined that the licensee had been relying on the plates to ensure operability of the CREVS system and that the 2001 modification had not been installed in accordance with a controlled process. In addition, the inspectors questioned the current operability of the CREVS and on May 10, 2005, the licensee initiated CR 2005-13856 to conduct an evaluation. The licensee concluded that the plates were acceptable to leave in place, and in fact, a permanent modification would be implemented to ensure system design was maintained. In the interim, the licensee elected to control system design by installing a clearance to ensure the plates were not inadvertently removed. The inspectors concluded that installing the plates not in accordance with the temporary system alteration process was a violation of regulatory requirements and had existed for approximately 3 years.

Analysis. The inspectors determined that the licensees failure to follow their temporary system alteration procedure to be a performance deficiency. The finding was greater than minor because it is associated with the plant modification design control attribute of the reactor safety barrier integrity cornerstone and affected the cornerstone objective of ensuring the reliability and capability of the control room emergency ventilation system.

The finding was of very low safety significance in accordance with NRC Inspection Manual Chapter 0609, Appendix A, Attachment 1, the SDP Phase 1 screening worksheet because it only represented a degradation of the radiological barrier function provided for the control room.

Enforcement. TS 6.8.1.a requires written procedures shall be established, implemented, and maintained covering the activities specified in Regulatory Guide (RG) 1.33, Revision 2, February 1978. RG 1.33, Appendix A, Item 1.c, identifies administrative procedures to be implemented for equipment control. Administrative procedure ADM-17.18, Temporary System Alteration, Revision 6, implements this requirement for temporary design alterations made to a system. Contrary to the above, ADM-17.18, Temporary System Alteration, Revision 6, was not implemented when on October 26, 2001, the licensee altered the CREVS system design without conducting the required assessments necessary to ensure the operability, reliability and capability of the CREVS. Because the failure to implement the subject procedure is of very low safety significance and has been entered in the licensees corrective action program (CR 2005-13856), this violation is being treated as an NCV, consistent with Section VI.A of the NRC Enforcement Policy: NCV 05000389/2005-03-01, Failure to Implement Temporary System Alteration Procedure.

Enclosure

Cornerstone: Emergency Preparedness (EP)

1EP6 Drill Evaluation a. Inspection Scope On May 24, 2005, the inspectors observed a quarterly emergency preparedness drill of the licensees emergency response organization for personnel in the simulator, Technical Support Center (TSC), and the Emergency Operations Facility (EOF). During this drill the inspectors assessed licensee performance to determine if proper emergency classification, notification, and protective action recommendations were made in accordance with emergency preparedness procedures. The inspectors evaluated the adequacy of the post drill critiques conducted in the EOF.

b. Findings No findings of significance were identified.

4. OTHER ACTIVITIES 4OA2 Identification and Resolution of Problems 1. Routine Review of Condition Reports (CRs)

a. Inspection Scope The inspectors performed a daily screening of all condition reports entered into the licensees corrective action program. The inspectors followed NRC Inspection Procedure 71152, Identification and Resolution of Problems, to help identify repetitive equipment failures or specific human performance issues for follow-up.

b. Findings and Observations There were no specific findings identified from this overall review of the CRs issued each day.

2. Annual Sample Review - Employee Concerns and Corrective Action Program Effectiveness In Dealing With Safety Conscious Work Environment Issues a. Inspection Scope During the week of May 23, 2005, the inspectors searched the licensees corrective action program (CAP) database for the past two years and reviewed 14 anonymous condition reports (CRs), CRs related to harassment and intimidation (H&I) or discrimination, and other CRs that potentially represented safety conscious work environment (SCWE) issues. The inspectors also interviewed the CAP supervisor, performance improvement department manager, maintenance manager, corporate speakout program manager, and 12 craft personnel in the mechanical, electrical, and Enclosure

instrumentation and control departments regarding the effectiveness of their CAP and employee concerns program (i.e., Speakout) for dealing with H&I, discrimination, and SCWE issues.

In addition, the inspectors reviewed 31 speak out program files for completeness, adequacy of the investigation conducted, file documentation, responsiveness to the individual, and responses to recommended corrective actions by station management.

The inspectors verified that the licensee responded to their CAP and speakout program concerns in a way and on a schedule that was appropriate to the concerns level of safety significance. The inspectors evaluated applicable condition reports against requirements of the licensees corrective action program as defined in their Administrative Procedure NAP 204, Condition Reporting.

b. Findings and Observations No safety significant findings were identified. In general, the SCWE at the St. Lucie plant appeared to be healthy where employees felt free to raise issues to their management without fear of retaliation. The licensees speakout program organization was effective in investigating and facilitating the resolution of employee concerns and appropriately addressed individuals concerns. The licensee was timely in response to employee concerns with the appropriate prioritization placed on the safety significance of the issue.

The inspectors identified that some responses to corrective actions contained in several speakout program files lacked specificity and sufficient detail to ensure all appropriate actions had been completed as required. Although not a program required by 10 CFR 50 Appendix B, the inspector noted that the overall quality of the speakout files was not as high as other CRs and quality assurance audit reports contained in their 10 CFR 50, Part B, corrective action program. Station management agreed that the documentation provided to speakout following completion of assigned corrective actions was not always adequate to verify the corrective actions were actually complete. The inspectors determined that in all cases the corrective actions completed were adequate and exceeded the corrective actions documented in the speakout program files. Some managers indicated that they were unsure of the expectation regarding documentation of completed corrective actions associated with speakout issues.

3. Semi Annual Trend Review a. Inspection Scope As required by Inspection Procedure 71152, Identification and Resolution of Problems, the inspectors performed a review of the licensees corrective action program 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 condition reports, licensee trending efforts, and licensee human performance self-assessments. The inspectors review nominally considered the six month period of January 2005 through June 2005, although some examples expanded beyond those dates when the scope of the trend warranted. This review also specifically examined Enclosure

equipment issues identified in selected System Health Reports, and adverse and negative trends identified by the Cross Functional Trend Coordinator Team Reports.

Furthermore, the inspectors verified whether adverse or negative trends and issues identified in the licensees reports were entered into the CAP.

b. Findings and Observations No violations of NRC requirements were identified. However, during routine tours of the Unit 1 and Unit 2 facilities including reactor auxiliary buildings, control rooms, AFW pump room areas, and ICW pump areas, the inspectors identified an increasing trend in plant configuration control deficiencies.

The inspectors identified a number of pipe cap and test connection fittings installed in the field that were not shown on piping and instrumentation drawings (CR 2005-7069);

temporary ladders and scaffolding in various locations that were not being procedurally controlled to ensure proper installation and removal (CR 2005-11854); unit 2 pressurizer heater control circuit wiring that was modified and not properly controlled (CR 2005-14616); modified floor drains in the unit 2 CREVS room (CR 2005-13856), and paint coatings on AFW piping with localized corrosion causing piping surface blistering requiring inspection and repair (CR 2005-10422). The inspectors discussed this trend with site engineering management and following additional inspector questions, the licensee identified several new configuration control deficiencies not previously identified and entered these findings into their CAP as CR 2005-17060.

4OA3 Event Followup

.1 (Closed) LER 05000335/2004-004-00, Dual Unit Loss of Offsite Power During Hurricane Jeanne On September 25, 2004, a dual-unit loss of offsite power (LOOP) occurred at the St.

Lucie site as a result of Hurricane Jeanne. The event was addressed in the licensees CAP as CR 2004-9001. This LER was reviewed and determined to be accurate and consistent with NRC observations following the LOOP. The event was also mentioned in Inspection Report (IR) 2004-05. No significant findings were identified and the event did not constitute a violation of NRC requirements. This LER is closed.

.2 (Closed) LER 05000389/2004-005-00, Manual Reactor Trip Due to Steam Generator Low Level On December 27, 2004, Unit 2 was in Mode 1 at 10 percent power when shortly after latching the turbine the 2A main feedwater pump automatically tripped on high level in the A-steam generator. With no feed pump in service, the B-steam generator narrow range water level decreased to the low level reactor protection system pre-trip setpoint and the operators manually tripped the reactor. The event was addressed in the licensees CAP as CR 2004-17851. This LER was reviewed and determined to be accurate and consistent with NRC observations following the trip. This event and its cause were previously documented and dispositioned in IR 2004-06. This LER is closed.

.2 (Closed) EEI 05000335, 389/1998014-07. Failure to Implement and Maintain in Effect Provisions of the NRC Approved Fire Protection Program as Described in the Final Safety Analysis Report (FSAR) and 10 Code of Federal Regulations (CFR) Part 50, Appendix R, Sections III.G.1.a and III.L.7.

Introduction. An in-office inspection was performed to review and close this open item.

Upon further inspector review, it was determined that a violation of 10 CFR 50, Appendix R, III.G.2 and III.G.3 was identified for failure to protect cables from fire damage which could result in a number of valves spuriously operating in a manner which could adversely affect safe shutdown capability. The mode of failure involved bypassing of limit switches and/or torque switches such that the valve could be damaged to the point where it could not be repositioned either manually or from the alternate shutdown panel.

The NRC applied enforcement and reactor oversight process discretion to the violation.

Description. An apparent violation was identified in NRC Inspection Report 50-335, 389/98-14. Specifically, the licensee did not have any documented evaluation addressing the potential for fire-induced short circuits on motor operated valve control cables to spuriously operate the valve while simultaneously bypassing the torque switches. This could result in valve damage which would preclude repositioning the valve to the safe shutdown position. Following the enforcement conference held to obtain facts on this apparent violation, the enforcement panel decided to maintain the issue as unresolved pending results of evaluations the licensee committed to perform.

Later, the issue of complex circuit failures became a generic agency issue, and the licensee delayed their analysis until the generic issue was resolved. Condition Report (CR) 00-0349 was written in March 2000 to track this issue while awaiting results of Nuclear Energy Institute (NEI)/Electric Power Research Institute (EPRI) circuit failure testing. Based upon the tests results and NEI 00-01, the licensee completed their analysis of valves important to safe shutdown. The analysis identified fifteen valves on Unit 1 and eleven valves on Unit 2 which were susceptible to the problem. The licensee prepared Plant Change/Modification 02154M to reconfigure the control circuit for susceptible valves to preclude one fire-induced short circuit from causing the valve to spuriously operate and simultaneously bypassing the torque switch. Work Orders have been scheduled for completion by September 2005. Currently, the affected Motor Operated Valves (MOV) are susceptible to this fire-induced malfunction, however, the Enclosure

licensee has implemented a roving fire watch in order to reduce the likelihood of a fire causing this failure.

Analysis. The inspectors determined that the licensees identification of 26 valves which could be damaged by fire-induced short-circuit through the mechanism of bypassing the torque switch constitutes a performance deficiency because it violated requirements in the area of fire protection and could have been prevented by the licensee. Additionally, the finding was associated with the protection against external factors attribute and affected the objective of the Mitigating Systems cornerstone to ensure the availability, reliability, and capability of systems that respond to initiating events. Therefore, the finding is greater than minor. The finding degraded the defense-in-depth for fire protection and is a circuit analysis problem involving spurious operations. Pursuant to NRC Inspection Manual Chapter 0305, Operating Reactor Assessment Program, Section 06.06.2, Violations in Specified Areas of Interest Qualifying for Enforcement Discretion, the NRC did not evaluate the significance of this finding through use of the Significance Determination Process and will not be entering it into the Reactor Oversight Program (ROP) Action Matrix. The finding was placed in the corrective action program as CR 98-0225, CR 00-0349 and CR 04-16518 and planned corrective actions are scheduled to be completed in a timely manner.

Enforcement. 10 CFR 50, Appendix R, III.G.2 states, in part, that where cables or equipment, including associated non-safety circuits that could prevent operation or cause maloperation due to hot shorts, open circuits, or shorts to ground, of redundant trains of systems necessary to achieve and maintain hot shutdown conditions are located within the same fire area outside of primary containment, one of three means of ensuring that one of the redundant trains is free of fire damage shall be provided.

Appendix R, III.G.3, allows for alternative shutdown capability independent of cables in the area under consideration in cases where the requirements of III.G.2 cannot be met.

Contrary to these requirements, cables for 26 valves were not protected such that one train of systems necessary to achieve and maintain hot shutdown conditions was not free of fire damage nor independent from the area under consideration. The plant has been in this condition since at least November 1998 when it was identified by the inspection team as documented in NRC Inspection Report 50-335, 389/98-14. Pursuant to NRC Enforcement Manual Section 8.1.7.1 ©), Fire Induced Circuit Failures, the NRC is exercising enforcement discretion for this noncompliance. The conditions for applying enforcement discretion in this case have been met. The licensee does not dispute these requirements were violated. The licensee took prompt compensatory action by posting fire watches once system analysis confirmed a non-compliance existed and entered the issue into the corrective action program. The planned corrective action contained in the approved plant modification and the schedule for implementation will result in corrective action being taken in a reasonable time frame.
