As recently as April 2, 2001 (CR 01-0714), licensee corrective action efforts to prevent lifting the 1A SDC suction relief valve were unsuccessful. A repeat event occurred on April 4 (CR 01-0741). The licensee has determined that past corrective actions were ineffective in preventing inadvertent relief valve liftings which adversely impact the orderly transition to SDC operations. The ineffective corrective actions to resolve a significant condition adverse to quality constituted a violation of Criterion XVI, Corrective Actions, of 10CFR50, Appendix B. These events were subsequently determined to be of very low safety significance due to the limited quantity of RCS coolant discharged through the relief valve, and the conclusion that the 1A SDC suction relief would have reseated (without operator action) once RCS pressure decreased below the blowdown margin setpoint. After the relief valve reseated, operators would have been able to proceed with unit cooldown. | .1 Declaration of Unusual Events Due to RCS Leakage in Excess of 10 Gallons per Minute | ||

This inspection was conducted by resident inspectors and several Region II inspectors; three reactor inspectors, a senior radiation specialist, and a security specialist. No findings of significance were identified by NRC inspectors during this inspection. The NRCs program for overseeing the safe operation of commercial nuclear power reactors is described at its Reactor Oversight Process website at http://www.nrc.gov/NRR/OVERSIGHT/index.html.
A. Inspector Identified Findings
No findings of significance were identified.
B. Licensee Identified Violations
Seven violations of very low safety significance identified by the licensee were reviewed by the inspectors. Corrective actions taken and planned by the licensee appeared reasonable.
These violations are listed in Section 4OA7 of this report.
Report Details
Summary of Plant Status:
Unit 1 began the report period at 70 percent power to conduct Main Steam Safety Valve testing. The unit was shutdown on April 2 for a planned refueling outage, and returned to service on April 30. Unit 1 operated at full power until June 5, when it automatically tripped due to low reactor coolant flow when the 1A2 Reactor Coolant Pump power supply breaker unexpectedly opened. The unit was restarted on June 7, and operated at essentially full power for the remainder of the report period.
Unit 2 remained at essentially full power for the entire report period.
1. REACTOR SAFETY
Cornerstones: Initiating Events, Mitigating Systems, Barrier Integrity (Reactor - R), and Emergency Preparedness (EP)
1R04 Equipment Alignment
.1 Partial Alignment Verifications
a. Inspection Scope
The inspectors conducted partial alignment verifications of the safety related systems listed below to evaluate the operability of the redundant trains or backup systems while the other trains were inoperable or out of service. The verifications included reviews of plant lineup procedures, operating procedures, and piping and instrumentation drawings which were compared with observed equipment alignments to identify any discrepancies which could affect Technical Specification (TS) operability of the redundant train or backup system.
- 1A Emergency Diesel Generator (during shutdown cooling operations)
- 1B Component Cooling Water (CCW) System
- 1A Emergency Diesel Generator (during 1B diesel radiator failure)
b. Findings
No findings of significance were identified.
.2 Complete Equipment Walkdown
a. Inspection Scope
The inspectors completed a detailed alignment verification of the Unit 2 Auxiliary Feedwater (AFW) system. This verification included a review of the lineup per procedure OP 2-07000222, Auxiliary Feedwater - Normal Operation. Applicable plant drawings, outstanding modifications, work orders, operator work arounds, Temporary System Alterations (TSA),
Condition Reports (CRs), and Plant Manager Action Items (PMAI) were also reviewed. The inspectors verified the following as required for TS operability:
- All valves were properly aligned
- There was no apparent significant leakage
- Electrical power was available
- Major system components were properly labeled, lubricated, and cooled
- Hangers and supports were correctly installed and functional
- Auxiliary equipment and debris did not interfere with system performance
The inspectors also verified that the licensee identified and documented equipment alignment problems at an appropriate threshold in the corrective action program.
b. Findings
No findings of significance were identified.
1R05 Fire Protection
.1 Fire Protection Review
a. Inspection Scope
The inspectors conducted tours of the fire areas listed below that are important to reactor safety and reviewed Administrative Procedure (AP)-1800022, Fire Protection Plan. The inspectors verified that any transient combustibles in the areas inspected were being controlled in accordance with licensee procedures. They also verified that all hot work or other ignition sources were being properly controlled by the licensee. The inspectors ensured that the material condition, operational status, and operational lineup of fire protection systems, equipment and features were in accordance with the Fire Protection Plan. Also, the inspectors confirmed that any compensatory measures in place were being performed per the licensees procedures, and the condition of fire barriers met all requirements of the Fire Protection Plan.

.2 (Open) Unresolved Item (URI) 50-335,389/98-201-09: Fire Mitigation System Does Not Meet Plant Licensing Basis Requirements/Commitments or Minimum Industry Codes and Standards for System Design and Testing
This item included four fire protection program issues concerning the design and testing requirements of the (1) fire detection systems, (2) water suppression systems, (3) Halon 1301 fire suppression system, and (4) standpipe and fire hose systems. These issues were previously discussed in NRC Inspection Report (IR) 50-335,389/98-201. Issue (4) was resolved in IR 50-335,389/98-14. This review addresses the closeout of items (1) and (2).
Item (3) of this URI, related to the Halon 1301 fire suppression system, remains open pending further NRC review.
Fire Detection System
Item (1) included issues identified by the licensees review of the fire alarm and detection systems on Units 1 and 2. Several non-conformances were identified between the installed fire detection systems, the National Fire Protection Association (NFPA) code of record, and/or the Updated Final Safety Analysis Report (UFSAR). These nonconforming conditions were documented by the licensee in CRs 98-0259, 98-0260, 98-0303, 98-0304,98-305, 98-306, 98-0453, and 98-0488. A regional based inspector performed an in-office review of the licensees CRs, problem evaluations, and associated corrective actions either planned or taken and concluded that these issues were appropriately addressed. The licensee determined that several of the items were acceptable to use-as-is with no corrective actions necessary. Other items required either plant changes/modifications (PC/M) or revisions to documents. The inspectors review determined that two of these licensee identified issues were violations of NRC requirements.
Operating License DPR-67 (Unit 1), Condition 2.C(3) and NPF-16 (Unit 2), Condition 2.C(20),
specify that the licensee implement and maintain in effect all provisions of the approved fire protection program as described in the UFSAR for the facility and as approved by NRC Safety Evaluation Reports (SER). Unit 1 UFSAR Table 9.5A-2 identified NFPA 72A-1972 as the code of record for original installation of the fire detection system. NFPA 72A-1972 requires that smoke detectors shall be located and adjusted to operate reliably in case of smoke at any part of the area protected. The NRC SER for Unit 2 dated October 1981 specifies that all fire detection systems used to actuate fire suppression systems will be Class A systems. Section 3.5.2.b of the Unit 2 UFSAR, Appendix 9.5A requires that fire protection systems shall be designed to ensure that any detector failure, single break, ground fault or wire to wire short will not prevent the transmission of an alarm, resulting in false operation, or cause a false indication of fire. Contrary to NFPA 72A-1972, a smoke detector (7B-4) was installed such that it could not detect smoke in the Unit 1 area it was protecting (Fire Zone 57) because it was surrounded by a Thermo-lag enclosure. The Unit 2 fire detection system had Class B style monitoring installed where Class A was required. With a Class B style electrical monitoring system, a single break or ground fault will result in a trouble condition for the initiating device circuits.
The inspector determined that these issues had a credible impact on safety because they could result in the delayed detection of a fire affecting safety related equipment. These violations, which are discussed in Section 4OA7 of this IR, were determined to be of very low safety significance because redundant safe shutdown functions were separated by appropriate fire rated barriers. These licensee identified issues were documented in CR(s)
98-0259 and 98-260. Item (1) of this URI is closed.
Water Suppression Systems
In Item (2), the licensee identified that the testing and installed design for the Unit 1 and Unit 2 water suppression sprinkler systems were not consistent with the licensees commitment to NFPA 13 or NFPA 15. The applicable NFPA requirements stated that the system deluge valve should be tested in a wet, pressurized condition. The licensees testing involved a dry inspection of the deluge valve internals. The installed design deficiencies included inadequate coverage of equipment in the Auxiliary and Emergency Diesel Generator spaces.
This issue was previously documented in Section F7.4.3, Fixed/Automatic Fire Suppression, of NRC IR 50-335,389/98-201.
The inspector conducted an in-office review of the licensees CRs which addressed these water suppression system deficiencies. The corrective actions in the CRs included test procedure changes, engineering evaluations, and PC/Ms to resolve the testing and installation design deficiencies.
Operating License DPR-67 (Unit 1), Condition 2.C(3) and NPF-16 (Unit 2), Condition 2.C(20),
specify that the licensee implement and maintain in effect all provisions of the approved fire protection program as described in the UFSAR for the facility and as approved by NRC Safety Evaluation Reports. Section 4.3.1.5 Automatic Water Suppression Systems of the UFSAR, Amendment 33, dated August 17, 1979, indicated that all station automatic water suppression systems conformed to NFPA 13 or 15. The failure of the licensee to maintain the Code requirements of the station water suppression systems for Units 1 and 2 is identified as a violation. The inspector determined that the issue had a credible impact on safety because the inadequate water suppression coverage did not assure adequate fire protection of safety related equipment in the Emergency Diesel Generator and Auxiliary buildings. This licensee identified violation, which is discussed in Section 4OA7 of this IR, was determined to be of very low safety significance because the safe shutdown functions of the plant were not affected due to separation by appropriate fire rated barriers. Therefore, safety related systems were not directly impacted by the water suppression system design deficiencies.
Additionally, subsequent completion of the appropriate system testing verified that the water suppression systems were functional. These licensee identified issues were documented in condition reports CRs98-307, 98-0405, and 98-0429. Item (2) of this URI is closed.

In interviewing these personnel, the inspector evaluated the effectiveness of their training and abilities to recognize aberrant behavioral traits, physiological indications of narcotic and alcohol use, and work call-out reporting procedures. Licensee compliance was evaluated against requirements in the St. Lucie Nuclear Plant Physical Security Plan and associated procedures, and 10 CFR Part 26, Fitness For Duty Programs.
b. Findings
No findings of significance were identified.
3PP2 Access Control
a. Inspection Scope
The inspector observed access control activities on April 24, and 25, 2001, and search/access control equipment testing was observed on April 25, 2001. In observing the access control activities, the inspector assessed whether officers could detect contraband prior to it being introduced into the protected area. The protective barriers for the Final
Access Control facility were inspected to ensure compliance with protection standards in the Physical Security Plan. Additionally, the inspector assessed whether the officers were conducting access control equipment testing in accordance with regulatory requirements through observation, review of procedures and log entries. Preventative and post maintenance procedures were evaluated and observed as performed. Lock, combination, and key control procedures were evaluated, as well as, aspects of the site access authorization program. Licensee compliance was evaluated against requirements in the St. Lucie Nuclear Plant Physical Security Plan and associated procedures, 10 CFR Part 73.55, Requirements for Physical Protection of Licensed Activities in Nuclear Power Reactors Against Radiological Sabotage, and Part 73.56, Personnel Access Authorization Requirements for Nuclear Power Plants.
b. Findings
No findings of significance were identified
4. OTHER ACTIVITIES
4OA1 Performance Indicator Review
.1 Barrier Cornerstone
a. Inspection Scope
The inspectors verified the accuracy of the performance indicators for RCS activity and RCS leakage which were reported to the NRC. The inspectors reviewed data applicable to four quarters of operation beginning with the second quarter of 2000 and ending the first quarter of 2001. The inspectors reviewed Operations logs, Chemistry Reports, and Condition Reports to ensure the data reported was complete and accurate.
b. Findings
No findings of significance were identified.
.2 Physical Protection Cornerstone
a. Inspection Scope
The inspector evaluated Florida Power and Light, and St. Lucie Nuclear Plant programs for gathering and submitting data for the Fitness-for-Duty, Personnel Screening, and Protected Area Security Equipment Performance Indicators. The evaluation included St.
Lucies tracking and trending reports and security event reports for the performance indicator data submitted from the first quarter to the fourth quarter of 2000. Licensee performance was evaluated against the guidance in NEI 99-02, Regulatory Assessment Performance Indicator Guideline.
b. Findings
No findings of significance were identified.
4OA3 Event Follow-up
.1 Declaration of Unusual Events Due to RCS Leakage in Excess of 10 Gallons per Minute
a. Inspection Scope
The licensee declared an Unusual Event on April 2 and again on April 4 when the suction relief of the 1A SDC System lifted unexpectedly during licensee attempts to place the SDC system into service. The inspectors responded to the control room and verified that plant conditions were stable and applicable operating procedures were being properly implemented. Inspectors also interviewed responsible Operations and Engineering personnel; attended Event Review Team meetings; and reviewed applicable CR dispositions.
b. Findings
Since initial unit operations, the licensee has experienced problems with the inadvertent lifting of SDC suction relief valves during the initial system alignment for cooldown. As recently as April 2, 2001 (CR 01-0714), licensee corrective action efforts to prevent lifting the 1A SDC suction relief valve were unsuccessful. A repeat event occurred on April 4 (CR 01-0741). The licensee has determined that past corrective actions were ineffective in preventing inadvertent relief valve liftings which adversely impact the orderly transition to SDC operations. The ineffective corrective actions to resolve a significant condition adverse to quality constituted a violation of Criterion XVI, Corrective Actions, of 10CFR50, Appendix B. These events were subsequently determined to be of very low safety significance due to the limited quantity of RCS coolant discharged through the relief valve, and the conclusion that the 1A SDC suction relief would have reseated (without operator action) once RCS pressure decreased below the blowdown margin setpoint. After the relief valve reseated, operators would have been able to proceed with unit cooldown.
Enforcement aspects of this issue are addressed in Section 4OA7 of this report.
.2 Unit 1 Reactor Trip
a. Inspection Scope
On June 4, Unit 1 tripped from full power when the 1A2 Reactor Coolant Pump (RCP)
breaker opened unexpectedly. An inspector responded to the control room and confirmed that the unit was stable in Mode 3, and that all safety-related mitigating systems had operated properly. Operator and plant response was verified to be as expected by reviewing plant parameters, strip charts, and the Sequence of Events Recorder; and discussing the event with plant operators and the licensees Event Review Team. The only equipment problems of any significance involved nonsafety-related secondary systems which did not adversely affect the operators ability to safely shutdown the unit.
The inspector also discussed the risk significance with the onsite risk analyst and Region II personnel, and verified that appropriate notifications were made in accordance with 10 CFR 50.72.
b. Findings
No findings of significance were identified.
.3 (Closed) Licensee Event Report (LER) 50-335/2001-02: Technical Specification Minimum Shutdown Cooling Loop Operation Requirement Violation
On April 3, 2001, while Unit 1 was in Mode 4, both trains of SDC were inadvertently tagged out while the 1A1 and 1A2 RCPs were already tagged out. This violated TS 3.4.1.3 which required at least two of four cooling loops (e.g. reactor coolant loops or SDC loops) to be operable in this mode. This condition lasted slightly more than two hours before the operators recognized the TS noncompliance and took actions to return the 1A1 RCP to service. The inspectors verified the immediate actions to restore compliance. The event was entered into the corrective action program as CR 01-0728. Appropriate corrective actions were implemented.
This event was determined to be of very low safety significance because the 1B SDC loop was only administratively inoperable and could have been easily returned to service. The 1B reactor coolant loop remained in operation the entire time. Enforcement aspects of this issue are addressed in Section 4OA7 of this report. This LER is closed.
.4 (Closed) LER 50-389/2001-01: Reactor Scram Due to Control Element Assembly Drops
This LER documented a Unit 2 reactor trip due to long-term thermal degradation of the 2B control element assembly motor generator voltage regulator. The LER was accurate and consistent with NRC observations following the reactor trip (see IR 50-335, 389/00-08).
The event was addressed in the corrective action program as CR 01-1443. The trip was uncomplicated and was determined to be of very low safety significance. This LER is closed.
.5 (Closed) LER 50-335/2001-05: Faulty CSAS Re-Sequencing Circuit Led to Operation Prohibited by Technical Specifications
This LER documented the licensees finding that the 1A EDG load re-sequencing circuit was inoperable during the previous fuel cycle due to a sticking Containment Spray Actuation System (CSAS) actuation relay. This condition could have caused the 1A EDG to become overloaded during certain design basis accidents (i.e. large loss of coolant accident, main steam or feed line break within containment, coincident with loss of offsite power). However, the susceptibility of an 1A EDG failure was limited to a specific five second period for containment spray actuation during EDG load sequencing. The event was addressed in the corrective action program as CR 01-1198.
The sticking relay was replaced, and the re-sequencing circuit was retested, during the recent Unit 1 refueling outage which restored operability of the 1A EDG. The inspectors
also verified that the licensees long-term corrective actions included fault analysis of the sticking relay and appropriately considered potential generic implications.
The NRC performed a phase 2 Significance Determination Process evaluation and determined that this event was of very low safety significance due to the limited window of susceptibility and the very low probability of initiating events and conditions necessary to overload EDG. With exceptions of short duration surveillance testing, the 1B EDG remained operable during the previous fuel cycle. Enforcement aspects of this event are addressed in section 4OA7 of this report. This LER is closed.
.6 (Closed) LER 50-335/2001-004: Mode 2 entered Without Both Hydrogen Recombiners Operable
On April 28, 2001, Mode 2 was entered on Unit 1 with the 1B Hydrogen Recombiner tagged out of service. This event was placed into the corrective action program as CR 01-1195. The apparent causes of the event were personnel errors and process deficiencies.
The inspectors verified that the licensee took immediate actions to correct the condition and restore compliance. The event was determined to be of very low significance because the redundant 1A hydrogen recombiner was operable the entire time.
Additionally, hydrogen recombiners are not needed until many hours after a design basis accident, and since the 1B recombiner was only out of service administratively (i.e.,
breaker tagged open) it could have been promptly restored by the operators. Enforcement aspects of this event are addressed in section 4OA7 of this report. This LER is closed.
4OA6 Meetings
Exit Meeting Summary
The inspectors presented the inspection results to Mr. D. Jernigan and other members of licensee management at the conclusion of the inspection on July 2, 2001. Interim exits by regional inspectors were held on April 5, 13, and 26, and June 14. The licensee acknowledged the findings presented.
The inspectors asked the licensee whether any of the material examined during the inspection should be considered proprietary. No proprietary information was identified.
4OA7 Licensee Identified Violations. The following findings of very low significance 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 dispositioned as NCVs.
If the licensee denies these non-cited violations, a response with the basis for denial should be provided, within 30 days of the date of this inspection report, 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.
NCV Tracking Number Requirement Licensee Failed To Meet
NCV 50-335/01-03-01 Operating License DPR-67 (Unit 1), Condition 2.C(3),
specifies that the licensee implement all provisions of the approved fire protection program as described in the UFSAR and as approved by NRC safety evaluation reports (SERs). UFSAR Table 9.5A-2 identified NFPA 72A-1972 as the code of record for original installation of the fire detection system. NFPA 72A-1972, requires that smoke detectors shall be located and adjusted to operate reliably in case of smoke at any part of the area protected. Contrary to the above, smoke detector 7B-4 could not detect smoke in the cable spreading room (Fire Zone 57) because it was surrounded by a Thermo-lag enclosure. This condition was identified on March 26, 1998. This issue is in the licensees corrective action program as CR 98-0259. (Green)
NCV 50-389/01-03-02 Operating License NPF-16 (Unit 2), Condition 2.C(20),
specify that the licensee implement and maintain in effect all provisions of the approved fire protection program as described in the UFSAR and as approved by NRC SERs.
NRC SER for Unit 2 dated October 1981 specifies that all fire detection systems used to actuate fire suppression systems will be Class A systems. Section 3.5.2.b of the Unit 2 UFSAR, Appendix 9.5A requires that fire protection systems shall be designed to ensure that any detector failure, single break, ground fault or wire to wire short will not prevent the transmission of an alarm, resulting in false operation, or cause a false indication of fire. The Unit 2 fire detection system had Class B style monitoring installed where Class A was required. With a Class B style electrical monitoring system, a single break or ground fault will result in a trouble condition for the initiating device circuits. This problem has existed since the original system installation and was discovered on February 14, 1998, and documented in the licensees corrective action program as CR 98-0260.
(Green)
NCV 50-335,389/01-03-03 Operating License DPR-67 (Unit 1), Condition 2.C(3) and NPF-16 (Unit 2), Condition 2.C(20), specify that the licensee implement and maintain in effect all provisions of the approved fire protection program as described in the UFSAR and as approved by NRC SERs. Section 4.3.1.5 Automatic Water Suppression Systems of the UFSAR, Amendment 33, dated August 17, 1979, indicated that all station automatic water suppression systems conformed to NFPA 13 or 15. The testing and installed design for the
water suppression sprinkler system was not consistent with NFPA 13 or NFPA 15. This condition has existed since the original system installation and was identified on February 20,1998, and documented in the licensees corrective action program as CR(s) 98-0307, 98-0405, 98-0429. (Green)
NCV 50-335/01-03-04 10CFR50 Appendix B, Criterion XVI requires that conditions adverse to quality be identified and corrected in a timely manner. The licensee determined that prior corrective actions did not prevent repetitive inadvertent lifting of the 1A SDC system suction relief valve while attempting to place the system into service. On April 2, and April 4, 2001, the licensee declared Unusual Events due to excessive RCS leakage when the 1A SDC suction relief valve lifted. These events were described in CRs 01-0714 and 01-741. (Green)
NCV 50-335/01-03-05 Technical Specification 3.4.1.3 requires at least two of four reactor and/or shutdown cooling loops to be operable in Mode 4. On April 3, 2001, three of the four Unit 1 cooling loops were out of service while in Mode 4. Actions were not initiated within one hour to restore a loop. This event was addressed in the licensees corrective action program as CR 01-0728. (Green)
NCV 50-335/01-03-06 Technical Specification 3.8.1.1 requires that both EDGs remain operable in Modes 1 through 4. On April 22, 2001, the licensee identified a sticking CSAS relay that could have caused the 1A diesel to become overloaded during certain design basis accidents for the period of October 1999 through April 2001. The event was captured in the licensees corrective action program as CR 01-1198.
(Green)
NCV 50-335/01-03-07 Technical Specification 3.6.4.2 requires that two hydrogen recombiners be operable in Modes 1 and 2. On April 28, 2001, the licensee inadvertently entered Mode 2 with the 1B Hydrogen Recombiner tagged out of service. This condition existed for about one day. This event was placed into the licensees corrective action program as CR 01-1195.
