4OA2 Identification and Resolution of Problems 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, in order to help identify repetitive equipment failures or specific human performance issues for follow-up.
Enclosure
b. Findings and Observations There were no specific findings identified from this overall review of the CRs issued each day.
4OA3 Event Followup
.1 (Closed) Licensee Event Report (LER) 05000335/2003-003-00, 01, and 02, Fire Seals Inoperable Due to Inadequate Qualification Testing On September 25, 2003, the licensee conducted a scheduled triennial fire protection audit and identified that 16 cable tray fire penetration seals were found inoperable due to inadequate qualification testing methods. The Gold Bond qualification fire test reports for 16 one sided marinite board cable tray penetration seals did not provide an adequate basis for qualification of the barriers as three-hour fire barriers. An additional 34 discrepant cable tray fire penetration seals were discovered during the confirmatory walkdown of the Unit 1 control room penetrations. Fourteen of those seals located in reactor turbine generator control boards were found with significant voids during the SL1-19 refueling outage. The root cause was the apparent lack of detail during the initial 10 CFR Part 50, Appendix R licensing activities. Corrective actions included implementing compensatory fire watches for the inoperable fire barriers, submitting a fire protection exemption for the Gold bond qualified penetrations, and repairs of control room floor penetrations.
The inspectors determined that the performance deficiency was a failure to demonstrate that 16 cable tray fire penetration seals were qualified as three-hour fire barriers per 10CFR50, Appendix R, III G.2 requirement. The finding is greater than minor because it involved the fire barrier equipment performance attribute of mitigating system cornerstone and affected the objective of ensuring that fire barrier equipment is available and capable to respond to an event. Significance Determination Process (SDP) Phase 1 Screening indicated that equipment and functions for the mitigation of fire initiating events, such as fire barriers, should be evaluated using IMC 609 Appendix F, Fires Protection SDP. A Regional Senior Reactor Analyst performed a Phase 3 evaluation under the Significance Determination Process. The evaluation concluded that the performance deficiency was of very low safety significance (Green). The key assumptions used in the evaluation were:
Actuation of the Halon system in the cable spreading room would not cause main control room evacuation.
The improperly certified seals met the definition in Appendix F of NRC Manual Chapter 0609 for Moderate A degradation.
The heat release rate for transient fires was 200 Kilowatts.
Initiating fire frequency for equipment in the applicable compartments, the heat release rate for fires from the equipment, spacial temperature distributions for these fires and propagation of fires in cable trays were as stated in Manual Chapter 0609, Appendix F.
Enclosure
All affected compartments were screened for credible fires via plant walk down. Using the tools available in Appendix F, fully developed fires were constructed with the equipment /cables on the other side of the degraded penetrations as the targets. The dominant accident sequences were:
1) Fully developed energetic electrical fires originating from Motor Control Center 1A-6 or Load Center 1A2 in the A Switchgear Room that manual suppression did not stop after 95 minutes. Thus, the fire propagated into equipment/operating circuits in the Cable Spread Room after passing through the degraded penetration.
2) Fully developed electrical fires originating from 480 VAC Panel in the A Switchgear Room that manual suppression did not stop after 160 minutes.
Thus, the fire propagated into operating circuits in the B Switchgear Room after passing through the degraded penetration.
The significance of this performance deficiency was reduced because only a moderate degradation in the penetrations existed. This afforded the fire brigade additional time to suppress the fire before critical safe shutdown equipment was damaged.
The issue was documented as condition report 03-3431 and had been identified by licensee personnel during fire protection engineering reviews. This licensee identified finding involved a violation of 10CFR50, Appendix R, III.G.2 , Fire Barriers. The enforcement aspects of the violation are discussed in Section 4OA7. This LER is closed.
.2 (Closed) LER 05000389/2004-001-00, Control Room Floor Fire Penetration Conditions Not Bounded By The Tested Configurations On March 4, 2004, as part of the extent of condition reviews associated with fire penetration deficiencies found in the St. Lucie Unit 1 control room floor, the licensee identified that several Unit 2 control room floor penetration seals located in the reactor turbine generator control boards were inoperable because conduits were not coated with mastic per design detail and the LER committed to rework the affected penetrations to their tested configuration. Subsequently, the licensee completed and approved an engineering evaluation (PSL-FPER-04-053) of the as found conditions in conformance with the requirements of GL 86-10, Implementation of Fire Protection Requirements.
The licensee concluded that the configurations were fully qualified as fire barriers and operable. Therefore, rework of the subject penetrations would not be required and the LER was no longer valid and retracted. Based on review of the LER, licensees engineering evaluation, and GL 86-10, the inspectors found that it was acceptable and no findings of significance were identified. This LER is closed.
Enclosure
.3 (Closed) LER 05000389/2004002-00, Reactor Auxiliary Building Missile Shield Doors Not Closed.
On October 4, 2004, with St. Lucie Unit 2 in Mode 3, the licensee identified that the east side reactor auxiliary building (RAB) 62 feet elevation exterior doors were open. The exterior doors were credited as missile shields. The apparent cause was lack of procedural guidance to ensure that the missile shield doors are kept closed during normal plant operations and severe weather conditions. Immediate corrective actions were to close and lock the missile shield doors. Planned corrective actions include procedure changes and training.
The inspectors determined that the performance deficiency was a failure to ensure that the missile shield doors were kept closed during normal operations and severe weather conditions for the past several years. This could have resulted in the plant being in a condition prohibited by TS. The finding is greater than minor because it involved the protection against external factors performance attribute of the mitigating system cornerstone and affected the objective of ensuring that missile shield equipment is available and capable to prevent damage to mitigating systems.
Significance Determination Process (SDP) Phase 1 Screening indicated that the finding is potentially risk significant due to an external event initiator and therefore, a Phase 3 analysis was required. A Regional Senior Reactor Analyst performed a Phase 3 evaluation under the SDP. Because of the low tornado frequency, and because there is no history of very strong tornados occurring in south Florida, the likelihood of severe damage to the specific targets of concern for the finding is very low. In addition, since only one train of equipment was impacted, mitigating systems were available to allow successful core cooling in the event of a tornado. Lastly, the inspectors observed that the area around the doors was well protected by other qualified equipment, which would further reduce the probability of a tornado generated missile entering the room. For these reasons, the Phase 3 analysis determined the risk associated with the finding to be Green.
The issue was documented as condition report (CR) 04-9935 and had been identified by licensee personnel during CR reviews. This licensee identified finding involved a violation of 10CFR50, Appendix B, Criterion V, Procedures. The enforcement aspects of the violation are discussed in Section 4OA7. This LER is closed.
.4 (Closed) LER 05000335/2004-002-00, B Train Emergency Core Cooling System Room Ventilation System Inoperable On May 17, 2004, with Unit 1 at 100 percent power, the licensee performed the emergency core cooling system (ECCS) equipment room ventilation surveillance test and it did not pass. Further investigation by the licensee determined that an open maintenance hatch in the auxiliary building affected the ability of the ECCS room ventilation system to maintain the required negative pressure. The open hatch was only evaluated and approved for its effect on the fire protection boundary and did not consider the effect on the ECCS equipment room ventilation boundary due to lack of procedural requirements. Corrective actions included closing the open hatch, Enclosure
performing a successful surveillance test, placing information placards, and procedure changes to ensure that fire breach permits consider potential effects on ventilation systems.
The inspectors determined that the performance deficiency was an inadequate procedure which resulted in the B train of the ECCS ventilation system being inoperable for a time period exceeding the 7 day allowed outage time of TS 3.7.8.1. The finding is greater than minor because it involved the degraded reactor auxiliary building barrier performance attribute of barrier integrity cornerstone and affected the objective of ensuring that physical design barriers protect the public from radio nuclide releases caused by accidents or events. Significance Determination Process (SDP) Phase 1 Screening for the containment barriers cornerstone indicated that the finding is of very low safety significance (Green) because it only represents a degradation of the radiological barrier function provided for the reactor auxiliary building.
The finding was documented as CR 04-2796 and had been identified by licensee personnel during the surveillance test. This licensee identified finding involved a violation of 10CFR50, Appendix B, Criterion V, Procedures. The enforcement aspects of the violation are discussed in Section 4OA7. This LER is closed.
4OA5 Other Activities
.1 (Closed) NRC Temporary Instruction 2515/150, Reactor Pressure Vessel Head and Head Penetration Nozzles (NRC Order EA-03-009) (Unit 2)
a. Inspection Scope The inspectors observed activities relative to inspection of the reactor pressure vessel head (RPVH) nozzles in response to NRC Bulletins 2001-01, 2002-01, 2002-02 and NRC Order EA-03-009 Modifying Licenses dated February 20, 2004. The inspection included review of Non-destructive examination (NDE) procedures, assessment of NDE personnel training and qualification, and observation and assessment of Visual testing (VT), Eddy current testing (ET) and Ultrasonic testing (UT) examinations. Discussions were also held with contractor representatives and other licensee personnel. The activities were examined to verify licensee compliance with regulatory requirements and gather information to help the NRC staff identify possible further regulatory positions and generic communications.
The inspectors reviewed the results of the licensees Bare Metal VT Examination, and specifically reviewed all (360 degrees) of RPVH bare metal VT video tape for RPVH Nozzle Nos. 16, 32, 40, 43, 56, 58, 68, 73, 91, and 101 (including surface area around nozzles), and reviewed still digital pictures for Nozzle Nos. 1, 14, 16, 23, 24, 32, 45, 56, 58, 62, 65, 73, 83, 100, and 101. The inspections were reviewed in order to verify absence of boron crystals indicative of a leak and to verify the integrity of the RPVH.
The inspectors reviewed the results of the licensees Volumetric UT Examination of RPVH Nozzles, and specifically observed a portion of in-process UT scanning of RPVH Nozzle Nos. 10, 54, 77, and 79, reviewed the UT results for RPVH Nozzle Nos. 14, 16, Enclosure
24, 27, 32, 35, 56, 58 and 83, and reviewed current outage UT results for 2003 repairs to RPVH Nozzle Nos. 18 and 72. UT observations/reviews included review of results intended to assess for leakage into the interference fit zone of the nozzles.
The inspectors observed and reviewed in-process weld repair activities for repair of a UT indication in Nozzle 32, including: observation of welding, review of repair traveler, review of welding procedure specification and procedure qualification record, review of welding material certified material test report, review of welder qualification records, and review of welding machine calibration records.
The inspectors reviewed ET Report 51-5057295-00, Eddy Current Examination of Vent Line Weld - St. Lucie Unit 2 - January 2005 for J-groove weld surface. The inspectors reviewed training and qualification records for NDE personnel who performed the above volumetric, visual, and surface examinations. The inspectors reviewed and discussed with licensee personnel the susceptibility ranking calculation and the basis for the RPVH temperatures used in the calculation. The basis for RPVH temperature input was reviewed to verify appropriate plant specific information was used in the time-at-temperature model for determining RPVH susceptibility ranking. The inspectors reviewed licensee procedures and inspection results for visual examinations to identify potential boric acid leaks from pressure-retaining components above the RPVH.
b. Observations and Findings 1) Verification that the examinations were performed by qualified and knowledgeable personnel.
The inspectors found that visual and volumetric inspections were being performed in accordance with approved and demonstrated procedures with trained and qualified inspection personnel. All examiners had significant experience, including experience inspecting RPVHs. In addition to qualification to Code requirements, VT, UT and ET personnel had additional training on RPVH inspections.
2) Verification that the examinations were performed in accordance with approved and demonstrated procedures.
The St. Lucie Unit 2 RPVH has 91 Control Element Drive Mechanism (CEDM) nozzles, 10 Incore Instrumentation (ICI) nozzles, and one vent nozzle, for a total of 102 nozzles.
The bare head remote visual inspection was performed in accordance with Framatome Procedure 54-ISI-367. The procedure used high-resolution miniaturized cameras delivered by a flexible inspection guide tube (CIGAR - Combined Inspection Grappling and Retrieval) which scanned a portion of each nozzle and surrounding head material with each pass. The scans covered the full circumference at the nozzle-to-top-of-head interface areas of all of the 102 nozzles and surrounding head surfaces. Prior to the inspection, the licensee requested relaxation from full coverage of the bare metal inspection based on limitations (areas under support legs for the reflective metal insulation) encountered in previous bare metal inspection. The relaxation (No. 4) was documented in Relaxation Request Letter L-2004-095, dated May 6, 2004. The Enclosure
relaxation request was approved by NRC Letter and attached Safety Evaluation Report dated December 27, 2004.
All 102 nozzles received remote mechanized UT examination from the inside diameter (ID) surface in accordance with Framatome approved Procedures 54-ISI-100-13 and 54-ISI-137-04 (vent nozzle only). The nozzles were ultrasonically inspected using an open-bore tool with all transducers mounted in a single inspection module and scanning axially (vertical up and vertical down). For all nozzles except the vent nozzle, the examination employed the TOFD technique using two sets (one 30 degree and one 45 degree) of 5 MHz, L-Wave transducers with the 30 degree directed in the axial direction and the 45 degree directed in the circumferential direction. In addition, the nozzle volume was scanned with two 60 degree, 2.25 MHz, shear wave transducers (one directed axially and one directed circumferentially) and a 0 degree, 5 MHZ L-Wave transducer. The inspection area extended from a minimum of 2" above the highest point on the J-groove welds to 0.5" below the lowest point on the J-groove weld. The reduced coverage below the J-groove weld was caused by the nozzle configuration associated with an internally threaded guide funnel which limited nozzle ID UT coverage. FPL Relaxation Request Letter L-2004-095, (Relaxation No. 3) dated May 6, 2004 requested approval to perform ID UT from the bottom of the welds to the maximum extent possible below the welds with supplemental non-visual NDE on the outside diameter (OD) where ID UT coverage was less than 0.5". This relaxation was approved by NRC Letter and attached Safety Evaluation dated December 27, 2004. The supplemental NDE was required for 17 Nozzles because of lack of coverage with the ID UT. OD UT was performed on 14 of the 17 and the other 3 were liquid penetrant (PT) examined because of inability to obtain the required coverage with OD UT. The OD UT employed a 34 degree L-Wave transducer directed circumferentially and two 45 degree shear wave transducers directed axially, one up and one down.
The vent nozzle inside surface was scanned with a 0 degree, 5.0 MHz, L-Wave transducer; a 45 degree, 5.0 MHz, shear wave transducer (axial flaw detection); and a 70 degree, 5.0 MHz, shear wave transducer (circumferential flaw detection). The surface of the J-groove weld for the vent nozzle was examined using ET inspection to evaluate for leakage through the J-groove weld.
The inspectors reviewed the Framatome procedures and observed in-process examinations as noted above. Approved acceptance criteria and/or critical parameters for RPVH leakage were applied in accordance with the demonstrated procedures.
Enclosure
3) Verification that the licensee was able to identify, disposition, and resolve deficiencies.
All indications of cracks, leakage or head wastage were required to be reported for further inspection and disposition. Based on observation of the inspection process, the inspectors considered deficiencies would be appropriately identified, dispositioned and resolved. UT indications were identified in Nozzles 16, 24, 27, 32, 56, and 58. All indications were below the J-groove welds in the non-pressure boundary part of the nozzles, orientated axially on the OD surface, starting near the bottom of the J-groove welds and extending downward, relatively short (0.23" - 0.390"), and relatively shallow (0.075" - 0.143") and not through wall. Three of the indications (Nozzles 16, 24, and 58)
did not exhibit crack characteristics, could not be verified using liquid penetrant examinations (PT white) or OD UT and were dispositioned acceptable without further work. The UT indications in Nozzles 32 and 56 were slightly deeper, exhibited crack characteristics and were repaired by removing the lower portion of the nozzle and replacing using the ID temper bead welding technique. The indication area on Nozzle 27 was PT inspected and did not confirm the indication, but revealed an indication in the J-groove weld. This nozzle was also repaired by cutting out and replacing the lower portion of the nozzle using the temper bead welding technique.
4) Verification that the licensee was capable of identifying the primary water stress corrosion cracking (PWSCC) and/or RPVH corrosion phenomenon described in NRC Order EA-03-009.
The licensee performed NDE examinations and bare metal visual inspection of all of the RPVH nozzles and the RPVH surfaces during the outage. As noted above, the NDE techniques had been previously demonstrated under the MRP Inspection Demonstration Program as capable of detecting PWSCC type manufactured cracks as well as cracks from actual samples from another site. Based on the demonstration, observation of in-process inspections, and review of inspection data for NDE and bare metal visual inspections, the inspectors concluded the licensee was capable of identifying cracking and/or corrosion as described in the NRC Order. As noted above, indications were identified in six nozzles, with three requiring repair.
5) Evaluate condition of the reactor vessel head (debris, insulation, dirt, boron from other sources, physical layout, viewing obstructions).
Although minor debris was noted, it did not appear to be associated with leaks from above the head or with nozzle leaks. There was some boric acid film/stains on some of the CEDM and ICI housings that was consistent with that observed during the last inspection (2003) and attributed to ICI leaks or non-operational CEDM venting. The inspection process required documenting any debris that might interfere with observation of the head to nozzle interface area and later removal of the debris with followup re-inspection to ensure the debris had not masked any boric acid deposits. This allowed 100 percent visual inspection of each of the RPVH nozzles with no significant obstructions impeding the examination.
Enclosure
6) Evaluate ability for small boron deposits, as described in NRC Bulletin 2001-01, to be identified and characterized.
The inspectors observed that the resolution of the video camera provided capability of detecting any debris or small boron deposits on the bare metal head. As noted above there were no obstructions to preclude essentially 100% visual inspection of the RPVH penetrations. As noted above, the loose debris noted at the RPVH to nozzle areas, was to be removed and the area re-inspected. Also, some boric acid film/stains were observed that were attributed to ICI leaks or CEDM venting from above the head. In addition to the video, a series of good resolution digital still pictures were taken of each nozzle to head area to aid in interpretation of the video results.
7) Determine the extent of material deficiencies (i.e., cracks, corrosion, etc.) that required repair.
No examples of RPVH leakage or material deficiencies were identified during the visual examinations. As noted above, UT examination identified indications of non-through wall flaws on the OD surface of six nozzles. Three were repaired by replacing a portion of the nozzles using the ID temper bead welding technique. The other three were dispositioned as metallurgical/geometric anomalies (not service related).
8) For each inspection method, determine if any significant impediments (e.g., centering rings, insulation, thermal sleeves, nozzle distortion, etc.) to effective examinations were identified.
No significant items that could impede the examination processes were noted during observation of the visual or NDE examinations.
(9) Determine the basis for the temperatures used in the susceptibility ranking calculation. Were the temperatures plan-specific measurements, generic calculations, etc.?
During the inspections documented in NRC Inspections reports 50-335,389/2003-005 and 50-335,389/2004-004, the inspectors reviewed the susceptibility calculation and the basis for the RPVH temperatures used in the calculation, as documented in FPL Engineering Evaluations and FPL Letters listed in List of Documents Reviewed (Attachment 1) below. The RPVH temperature used for the calculation was taken from Combustion Engineering Owners Group (CEOG) Report CE-NPS-1074, which documented an analysis of core bypass flow to determine a reduction from T-hot called T-mix. During the current inspection, the inspectors reviewed the updated effective Degradation Years (EDY) calculation.
10) Determine if the methods used for disposition of NDE identified flaws were consistent with NRC flaw evaluation guidance. If not, was the method more restrictive?
The indications considered to be flaws were dispositioned in accordance with the current flaw evaluation guidance. Flaws in three nozzles were repaired.
Enclosure
11) Determine if procedures existed to identify potential boric acid leaks from pressure-retaining components above the RPVH and if the licensee performed proper followup for indications of boric acid leaks.
Operating Procedure 2-0120022 requires inspection of the reactor vessel head area and components above the head for evidence of leakage. Documentation and disposition of inspection findings are performed in accordance with Plant Administrative Procedure ADM-29.03, Boric Acid Corrosion Control Program. The inspectors reviewed the completed inspection results for Procedure 2-0120022 for the current Unit 2 outage.
There was some evidence of light boron on the head above one nozzle away from the nozzle that was shown to come from the insulation above. Some boric acid film/stains on some of the nozzles were consistent with that observed and documented in the last outage. There was also some rust stains on the head outside the shroud. The boric acid residue/stains and rust were attributed to ICI leaks or non-operational CEDM venting.
CR 05 -0880 was issued to document investigation and disposition of these conditions.
There was a history of previous ICI flange leakage.
.2 (Closed) TI 2515/160, Pressurizer Penetration Nozzles and Steam Space Piping Connections in U.S. Pressurized Water Reactors (NRC Bulletin 2004-01) (Unit 2)
The inspectors reviewed the licensees 60-day response to NRC Bulletin 2004-01, dated July 27, 2004. The inspectors verified that the licensees examinations conducted during this outage were consistent with the licensees response.
The inspectors conducted an independent walkdown of the top of the pressurizer to ensure that the physical conditions of the pressurizer penetrations and welds were clean and accessible for the prescribed inspections, and that there were no problems with debris, insulation, dirt, boron from other sources, physical layout, or viewing obstructions, which could have interfered with the identification of relevant indications. The inspectors also independently reviewed photographs of the subject penetrations and welds to verify that the licensee was able to conduct an adequate Bare Metal Visual (BMV) inspection in accordance with their commitment stated in the response to Bulletin 2004-01. BMV inspection data sheets and pictures were reviewed for the following components:

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 dispositioned as NCVs.
.1 10CFR50, Appendix R, III G.2 requires in part that fire barriers need to have a fire rating of three hours. Appendix A to Branch Technical Position (APCSB) 9.5-1 provided guidance regarding cable and cable tray penetration seals in that the seals should provide protection equivalent to the associated fire barrier, and as a minimum meet the requirements of ASTM E-119-73, Fire test of Building Construction and Materials. The test demonstrated that, for the three hour test period, each fire stop design contained the fire and the fire did not pass through the fire stop. Contrary to the above, on September 25, 2003, 16 cable tray fire penetration seals were found inoperable because the test results did not provide an adequate basis for qualification of the barriers as three hour fire barriers since 1977. This was identified in the licensees corrective action program as CR 03-3431. This finding was determined to be of very low safety significance (Green)
by a Phase 3 evaluation under the SDP. This finding is also discussed in Section 4OA3.
.2 10CFR50, Appendix B, Criterion V, requires, in part, that activities affecting quality shall be prescribed by documented instructions, procedures, or drawings, of a type appropriate to the circumstances and shall be accomplished in accordance with these instructions, procedures, or drawings. Contrary to the above, on October 4, 2004, the licensee identified that due to lack of procedural guidance, the missile shield doors could have been open for the past several years which could result in the plant being in a condition prohibited by TS. This was identified in the licensees corrective action program as CR 04-9935. This finding was determined to be of very low safety significance (Green) by a Phase 3 evaluation under the SDP. This finding is also discussed in Section 4OA3.

.3 10CFR50, Appendix B, Criterion V, requires, in part, that activities affecting quality shall be prescribed by documented instructions, procedures, or drawings, of a type appropriate to the circumstances and shall be accomplished in accordance with these instructions, procedures, or drawings. Contrary to the above, on May 17, 2004, the B train of the ECCS ventilation system was determined to be inoperable for longer than the 7 day TS allowed outage time due to an inadequate procedure, since April 20, 2004. This was identified in the licensees corrective action program as CR 04-2796. This finding was determined to be of very low safety significance (Green) by a Phase 1 Screening evaluation under the Significance Determination Process. This finding is also discussed in Section 4OA3.
