: On April 30, 2009, the 480v engineered safeguards motor control center 3B1 (ES MCC-3B1) de-energized as a result of an arc flash generated when test equipment was connected to an ES MCC-3B1 circuit breaker. Prior to the event, test equipment was being connected to various circuit breakers per WO1496283 in order to collect data for the purpose of updating emergency diesel margin calculations. During the performance of the Work Order, electricians connected test leads to the "line" side of the "B" phase of circuit breaker MTMC-5-8AR vice the "load" side as directed by the WO instructions. The connection of the test equipment introduced a phase-to-ground arc flash that ultimately caused the de-energization of ES MCC-3B1. | : On April 30, 2009, the 480v engineered safeguards motor control center 3B1 (ES MCC-3B1) de-energized as a result of an arc flash generated when test equipment was connected to an ES MCC-3B1 circuit breaker.

Following the loss of the ES MCC-3B1, safety-related equipment makeup and purification system (MU) main lube oil pump MUP-2C was declared inoperable. Loss of main lube oil pump MUP-2C resulted in HPI system make-up pump MUP-1C being declared inoperable. Combined with a pre-existing clearance order (tagout) on HPI valve MUV-26, this condition resulted in one pump operation through two (2) injection legs. The HPI System was declared inoperable and ITS 3.0.3 was entered. Emergency diesel generator EGDG-1B and other mitigating systems associated with 480v ES MCC 3B1 was also declared inoperable. Due to the electrical transient, reactor building air handling fan and several control room complex loads were also tripped off. In addition, several extraction steam bypass valves and turbine drain system valves opened. The unit load demand was immediately taken to hand and reactor power was lowered due to the additional steam flow. The extraction steam bypass valves and turbine drain system valves were closed. The highest power level observed was approximately 2616 megawatt thermal (MWth) and the licensed power limit for Crystal River 3 is 2609 MWth. | Following the loss of the ES MCC-3B1, safety-related equipment makeup and purification system (MU) main lube oil pump MUP-2C was declared inoperable.

ITS 3.0.3 was exited 1 hour and 24 minutes later when the clearance order on MUV-26 was lifted to restore the downstream cross-tie line and the downstream HPI line resulting in three (3) available injection legs. The event was reported to the NRC on June 22, 2009, pursuant to 10 CFR 50.73(a)(2)(i)(B) for being in ITS 3.0.3 for greater than one hour. The licensee determined there were two root causes associated with this event. The first root cause was for working on energized equipment with less than adequate controls in place. Specifically, the work order allowed work on energized equipment when it was possible to perform the work with the equipment out of service.

: (a) The applicable procedures recommended in Regulatory Guide 1.33, Revision 2, Appendix A, February 1978." Regulatory Guide 1.33, Revision 2, Appendix A, February 1978, Section 3(b) states "Instructions for energizing, filling, venting, draining, startup, shutdown, and changing modes of operation should be prepared, as appropriate, for the following systems: Control Rod Drive System (including part length rods)." Contrary to the above, the licensee failed to follow the provisions of PM-126, Electrical Checks of CRD [Control Rod Drive] Power Train. Failure to follow this procedure is a violation of Improved Technical Specifications. This failure resulted in a manual reactor trip. Because the finding is of very low safety significance and has been entered into the licensee's corrective action program as NCR 351705, this violation is being treated as an NCV consistent with Section VI.A.1 of the NRC Enforcement Policy: NCV 05000302/2009005-02, Manual Reactor Trip Due To Group 7 Control Rods Insertion Caused by Inadequately Protected Test Jumper. | |||

SUBJECT: CRYSTAL RIVER UNIT 3 - NRC INTEGRATED INSPECTION REPORT 05000302/2009005
Dear Mr. Franke:
On December 31, 2009, the US Nuclear Regulatory Commission (NRC) completed an inspection at your Crystal River Unit 3. The enclosed inspection report documents the inspection findings, which were discussed on January 11, 2010, with you and other members of your staff.
The inspection examined activities conducted under your license as they related to safety and compliance with the Commission's rules and regulations and with the conditions of your license. The inspectors reviewed selected procedures and records, observed activities, and interviewed personnel.
Based on the results of this inspection, two self-revealing findings of very low safety significance (Green) were identified. The findings were both determined to involve a violation of NRC requirements. However, because of the very low safety significance of the issues and because they were entered into your corrective action program, the NRC is treating the issues as Non-Cited violations (NCV) consistent with Section VI.A of the NRC Enforcement Policy. Also, one licensee identified violation which was of very low safety significance is listed in Section 4OA7 of the report. If you contest the non-cited violations, 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 20555-001; 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 Crystal River Unit 3 site. In addition, if you disagree with the characterization of any finding in this report, you should provide a response within 30 days of the date of this inspection, with the basis for your disagreement, to the Regional administrator, Region II, and the NRC Resident Inspector at Crystal River Unit 3. The information you provide will be considered in accordance with Inspection Manual Chapter 0305.
FPC 2 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 the NRC's document system (ADAMS).

SUMMARY OF FINDINGS
IR 05000302/2009005; 10/01/2009 -12/31/2009; Crystal River Unit 3; Followup of Events and Notices of Enforcement Discretion
The report covered a three month period of inspection by resident inspectors, two regional project engineers, four regional reactor inspector, one regional construction project inspector, one regional intern and four regional health physicists. Two self-revealing NCVs were identified. The significance of most findings is identified by the 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 4, dated December 2006.
A. NRC Identified
& Self-Revealing Findings
Cornerstone: Mitigating Systems
- Green.
A self-revealing Non-Cited Violation (NCV) of Improved Technical Specification (ITS) 5.6.1.1.a was identified for the failure to follow a plant procedure which resulted in a loss of a 480 volt engineered safeguards motor control center (ES MCC)-3B1. Concurrent with pre-existing conditions, the high pressure injection (HPI) system was declared inoperable and ITS 3.0.3 was entered for a period of one hour and 24 minutes. The licensee entered this issue into the corrective action program as nuclear condition report (NCR) 333515.
The finding was more than minor since it affected the equipment availability attribute of the mitigating system cornerstone and resulted in ITS 3.0.3 entry for the HPI system being inoperable. The finding was evaluated against NRC Phase 1 Significance Determination Process (SDP) and Phase 2 SDP was required due to a loss safety function of the HPI system. A Regional Senior Reactor Analyst performed a Phase 3 SDP evaluation and concluded this finding was of very low safety significance (Green).
The major assumptions of the evaluation were that the HPI function was out of service for exposure period (1 .5 hours5.787037e-5 days <br />0.00139 hours <br />8.267196e-6 weeks <br />1.9025e-6 months <br />) and there would be no recovery of the de-energized motor control center. The dominant accident sequence involved a support system failure of the Emergency Feedwater (EF) Indication and Control System rendering Main Feedwater and automatic control of EF unavailable, operators were unable to manually control EF flow causing its failure and with the HPI function lost due to the performance deficiency, core damage ensued. The inspectors determined the cause of the finding is related to the cross-cutting area of Human performance with a work practices aspect H.4 (c)). Specifically, work scope changes involving safety-related equipment did not receive the appropriate level management oversight resulted in a plant procedural violation. (Section 4OA3.2)
Cornerstone: Initiating Events
- Green.
A self-revealing NCV of Improved Technical Specification (ITS) 5.6.1.1.a was identified for the failure to follow the provisions of preventative maintenance procedure PM-126, Electrical Checks of CRD [Control Rod Drive] Power Train. Failure to follow
PM-126 caused the failure of the Group 7 control rod programmer during maintenance and resulted in the unexpected insertion of the Group 7 control rods fully into the core. This unexpected insertion of these control rods into the core caused control room operations personnel to manually trip the reactor from 100 percent power. The licensee entered this issue into the corrective action program as NCR 351705.
This finding was determined to be more than minor because it was associated with the initiating events cornerstone attribute of Human Performance, and adversely affected the cornerstone objective to limit the likelihood of those events that upset plant stability and challenge critical safety functions during at-power operations. The finding was evaluated using Phase 1 of the At-Power SDP, and was determined to be of very low safety significance (Green) because it did not contribute to both the likelihood of a reactor trip and the likelihood that mitigating equipment or functions were not available. The cause of this finding was directly related to the cross-cutting area of Human Performance with a work practices aspect (H.4 (b)). Specifically, the workers failed to follow the preventative maintenance procedure. (Section 4OA3.3)
B. Licensee Identified Violations
One violation of very low safety significance, which was identified by the licensee, has been reviewed by the inspectors. Corrective actions taken or planned by the licensee have been entered into the licensee's corrective action program. The violation and corrective action tracking number is listed in Section 4OA7 of this report.

RADIATION SAFETY
Cornerstones: Occupational Radiation Safety (OS) and Public Radiation Safety (PS)2OS1 Access Control To Radiologically Significant Areas The inspectors evaluated licensee guidance and its implementation for controlling worker access to radiologically significant areas and for monitoring jobs in-progress. The inspectors directly observed implementation of administrative and physical radiological controls; evaluated radiation worker (radworker) and health physics technician (HPT) knowledge of and proficiency in implementing radiation protection (RP) requirements; and assessed worker exposures to radiation and radioactive material.
During facility tours, the inspectors directly observed postings and physical controls for radiation area and high radiation (HRA) locations established within radiologically controlled area (RCA) locations of the auxiliary building, reactor building, and radioactive waste (radwaste) processing and storage facilities. The inspectors independently measured radiation dose rates or directly observed conduct of licensee radiation surveys for selected RCA areas. Results were compared to current licensee surveys and assessed against established postings and Radiation Work Permit (RWP) controls. Licensee key control and access barrier effectiveness were observed and evaluated for selected Locked High Radiation Area (LHRA) locations. Changes to procedural guidance for LHRA and Very High Radiation Area controls were discussed in detail with select health physics (HP) supervisors. Physical controls for storage of irradiated material within the spent fuel pool (SFP) were observed and discussed with cognizant licensee representatives. In addition, licensee controls for areas where dose rates could change significantly as a result of Refueling Outage 16 (RFO 16) tasks or radwaste processing activities were reviewed and discussed.
The inspectors attended selected pre-job briefings and remotely observed selected activities associated with the steam generator (SG) replacement activities during RFO 16. The observations afforded the inspectors opportunity to assess various aspects of the RP program including communications between HP and various workgroups, internal communications, RWP controls, contamination control, surveys, radiation worker adherence to RWP and other HP guidance, HPT proficiency in providing job coverage and supervisory willingness to intervene when conditions deviated from expected.
The inspectors observed various other work activities including radiography in the radiography testing bunker, "A" SG upper manway diaphragm removal, and shielding of various pipes and scaffold building in the reactor building. The inspectors evaluated electronic dosimeter (ED) alarm setpoints with area radiation survey results and discussed ED alarm response actions with radiation workers, HPTs, and RP supervisors.
The inspectors evaluated the effectiveness of radiation exposure controls and monitoring, including air sampling, barrier integrity, engineering controls, and postings through a review of both internal and external exposure results. Licensee evaluations of skin dose resulting from discrete radioactive particle or dispersed skin contamination events were reviewed and assessed. For HRA tasks involving significant dose rate gradients, the inspectors evaluated procedural guidance for the use and placement of whole body and extremity dosimetry to monitor worker exposure.

The inspectors' review was focused on repetitive equipment issues, but also considered the results of daily inspector CAP item screening discussed in section 4OA2.1 above, plant status reviews, plant tours, and licensee trending efforts. The inspectors' review nominally considered the six month period of July 2009 through December 2009. The review also included issues documented in the licensee's Equipment Performance Priority List dated December 16, 2009, and various 3 rd quarter 2009 departmental CAP Rollup & Trend Analysis reports, nuclear oversite reports and maintenance rule (MR) reports. Corrective actions associated with a sample of the issues identified in the licensee's corrective action program were reviewed for adequacy.
b. Findings and Observations
No findings of significance were identified. The inspectors evaluated the licensee's trend methodology and determined that the licensee had performed a detailed review.
The inspector's review of licensee performance over the last six months noted the continuance of a negative trend associated with battery grounds. This negative trend was identified by the licensee and documented in NCR 200813 in 2006. The licensee has been effective in the identification and repair of equipment causing the grounds when the grounds are not intermittent. An upgrade of the ground detection system starting in 2010 should aid in the identification of equipment causing intermittent grounds.
.3 Annual Sample Review
a. Inspection Scope
The inspectors reviewed priority two NCR 357012 that addressed an adverse trend in the control of test equipment and procedure use and adherence. Improper control of test equipment and inadequate procedure use and adherence resulted in two plant trips in 2009 and a loss of an engineering safeguards motor control center (MCC 3B1). A common cause investigation of these three events was initiated to identify any work behaviors and any latent organizational weaknesses that needed to be addressed. The inspectors checked that the issue had been completely and accurately identified in the licensee's corrective action program; safety concerns were properly classified and prioritized for resolution, common cause determination was sufficiently thorough, and appropriate corrective actions were initiated. The inspectors also evaluated the NCR using the requirements of the licensee's CAP as delineated in corrective action procedure CAP-NGGC-200, Corrective Action Program.
b. Findings and Observations
No findings of significance were identified. The regulatory aspects associated with each plant event described above are documented in section
4OA3 of this report and NRC integrated inspection report 05000302/2009002.
The inspectors found that the licensee's common cause investigation was both comprehensive and thorough. The use of Progress Energy personnel from another site on the investigational team personnel resulted in an unbiased look into the three events. Corrective actions that include the installation of engineered test points for routine connection of test equipment and the implementation of a site human performance excellence plan appear to be reasonable.
4OA3 Follow-up of Events and Notices of Enforcement Discretion
.1 Operator Performance During Non-Routine Event
a. Inspection Scope
For the one non-routine plant evolution described below, the inspectors reviewed the operating crew's performance, operator logs, and the overall plant response to the following one event.
- NCR 358724, Internal containment concrete cracking found during creation of a temporary containment opening to support steam generator replacement
b. Findings
No findings of significance were identified. During the creation of temporary opening in the reactor containment building to support steam generator replacement, the licensee discovered an internal crack in the concrete containment. The circumstances associated with the crack in the concrete containment wall are being assessed by an NRC special inspection team. The results of that inspection will be documented in NRC special inspection report 05000302/2009007.
.2 (Closed) LER 05000302/2009-002-00: In Technical Specification 3.0.3 for Greater
Than One Hour due to a Loss of a Motor Control Center During Testing
a. Inspection Scope
The inspectors reviewed the root cause evaluation associated with LER 05000302/2009-002-00 to determine whether a performance deficiency was involved, corrective actions were adequate, and to determine the safety significance. The inspectors also reviewed the LER to verify its accuracy and completeness.
b. Findings
Introduction:
A Green self-revealing Non-Cited Violation (NCV) of Improved Technical Specification (ITS) 5.6.1.1.a for failure to follow a plant procedure resulted in a loss of 480 volt engineered safeguards motor control center (ES MCC)-3B1. Concurrent with pre-existing conditions, the high pressure injection (HPI) system was declared inoperable and ITS 3.0.3 was entered for a period of one hour and 24 minutes.
Description
- On April 30, 2009, the 480v engineered safeguards motor control center 3B1 (ES MCC-3B1) de-energized as a result of an arc flash generated when test equipment was connected to an ES MCC-3B1 circuit breaker. Prior to the event, test equipment was being connected to various circuit breakers per WO1496283 in order to collect data for the purpose of updating emergency diesel margin calculations. During the performance of the Work Order, electricians connected test leads to the "line" side of the "B" phase of circuit breaker MTMC-5-8AR vice the "load" side as directed by the WO instructions. The connection of the test equipment introduced a phase-to-ground arc flash that ultimately caused the de-energization of ES MCC-3B1.
Following the loss of the ES MCC-3B1, safety-related equipment makeup and purification system (MU) main lube oil pump MUP-2C was declared inoperable. Loss of main lube oil pump MUP-2C resulted in HPI system make-up pump MUP-1C being declared inoperable. Combined with a pre-existing clearance order (tagout) on HPI valve MUV-26, this condition resulted in one pump operation through two
- (2) injection legs. The HPI System was declared inoperable and ITS 3.0.3 was entered. Emergency diesel generator EGDG-1B and other mitigating systems associated with 480v ES MCC 3B1 was also declared inoperable. Due to the electrical transient, reactor building air handling fan and several control room complex loads were also tripped off. In addition, several extraction steam bypass valves and turbine drain system valves opened. The unit load demand was immediately taken to hand and reactor power was lowered due to the additional steam flow. The extraction steam bypass valves and turbine drain system valves were closed. The highest power level observed was approximately 2616 megawatt thermal (MWth) and the licensed power limit for Crystal River 3 is 2609 MWth.
ITS 3.0.3 was exited 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> and 24 minutes later when the clearance order on MUV-26 was lifted to restore the downstream cross-tie line and the downstream HPI line resulting in three
- (3) available injection legs. The event was reported to the NRC on June 22, 2009, pursuant to 10 CFR 50.73(a)(2)(i)(B) for being in ITS 3.0.3 for greater than one hour. The licensee determined there were two root causes associated with this event. The first root cause was for working on energized equipment with less than adequate controls in place. Specifically, the work order allowed work on energized equipment when it was possible to perform the work with the equipment out of service. The second root cause was attributed to procedure adherence / documentation culture not meeting expectations. Specifically, electricians improperly made the decision to deviate from work order instructions based on verbal directions from their supervisor, and without having the work instructions formally revised in accordance with the licensee's Work Management Process procedure.
Analysis:
A failure to follow written work instructions in accordance with plant procedure ADM -NGGC-0104, Work Management Process, resulted in a loss of ES MCC-3B1 was a performance deficiency. Loss of ES MCC-3B1 and concurrent with pre-existing conditions caused the HPI system inoperability. The finding was more than minor since it affected the equipment availability attribute of the mitigating system cornerstone and resulted in ITS 3.0.3 entry for the HPI system being inoperable for approximately 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> and 24 minutes. The inspectors evaluated the finding against NRC SDP Phase 1 and determined that SDP Phase 2 was required because there was a loss of the HPI system safety function with no credit for the non-safety related direct current backup lube oil pump (MUP-3C). In addition to loss of 480 volt ES MCC-3B1 and reactor building air handling fan/control room complex loads tripped off and several extraction steam and turbine drain system valves opened during the electrical transient. Therefore, NRC Phase 3 evaluation was warranted to determine the level of safety significance. A Regional Senior Reactor Analyst performed a Phase 3 Significance Determination Process evaluation and concluded the performance deficiency was of very low safety significance (Green). The major assumptions of the evaluation were that the High Head Safety Injection function was out of service for the exposure period, the exposure period was 1.5 hours5.787037e-5 days <br />0.00139 hours <br />8.267196e-6 weeks <br />1.9025e-6 months <br /> and there would be no recovery of the de-energized motor control center. The dominant accident sequence involved a support system failure of the Emergency Feedwater Indication and Control System rendering Main Feedwater and automatic control of Emergency Feedwater unavailable, operators were unable to manually control Emergency Feedwater flow causing its failure and with the High Head Safety Injection function lost due to the performance deficiency, core damage ensued. The inspectors determined the cause of the finding is related to the cross-cutting area of Human Performance with a work practices aspect (H.4 (c)). Specifically, the licensee failed to ensure that work scope changes involving safety-related equipment receive the appropriate level supervisor and management oversight which resulted in a plant procedural violation.
Enforcement:
ITS 5.6.1.1.a states, in part, that written procedures shall be established, implemented, and maintained covering safety-related equipment maintenance activities recommended in Regulatory Guide 1.33, Revision 2, Appendix A, February 1978. Section 9.8 of plant procedure ADM-NGGC-0104, states that maintenance of safety-related equipment shall be pre-planed and performed in accordance with written procedures, documented instructions, or drawing appropriate to circumstances. Section 9.11.6 of plant procedure ADM-NGGC-0104 also states that the implementer review process provides an opportunity, prior to performing a given task, to examine the work package for adequacy, make any necessary changes, ensure specified parts are correct and available, and walk down the work to be performed.
Contrary to the above, on April 30, 2009, maintenance personnel failed to follow written work instructions in accordance with plant procedure ADM-NGGC-0104, Work Management Process, to ensure that work scope changes involving safety-related equipment receive the appropriate level of review and approval prior to proceeding with work. As a result, maintenance personnel improperly connected test equipment to an ES MCC-3B circuit breaker which resulting in the de-energization of ES MCC-3B1. Concurrent with pre-existing conditions, the HPI system was declared inoperable and ITS 3.0.3 was entered for a period of one hour and 24 minutes before the appropriate clearances were lifted to restore the HPI system to an operable status. Because this violation was of very low safety significance and it was entered into the licensee's corrective action program as NCR 333515, this violation is being treated as an NCV, consistent with section VI.A.1 of the NRC Enforcement Policy. This finding is identified as NCV 05000302/2009005-01, Failure to Follow a Plant Procedure Resulted in an Inoperable HPI System.
.3 (Closed) LER 05000302/2009-003-00, Manual Reactor Trip Due To Group 7 Control
Rods Insertion Caused By Inadequately Protected Test Jumper
a. Inspection Scope
On August 24, 2009, while operating at 100 percent power, the Unit 3 Control Room operators received multiple alarms and observed the Group 7 control rods fully insert into the reactor core. The reactor was manually tripped prior to automatic actuation of the Reactor Protection System (RPS). This unexpected control rod insertion was caused by the failure of the Group 7 control rod programmer which resulted from inadvertent test jumper contact while using an improperly fused test jumper during maintenance on the system. The RPS responded as expected to the manual trip signal, control rods fully inserted. During and following the scram, all safety-related mitigating systems operated as designed, and all operator actions in response to the scram were deemed to be appropriate. This LER and its associated Nuclear Condition Report (NCR) 351705, including the Root Cause Analysis (RCA) for the event, as well as other NCR's associated with this event, were reviewed by the inspectors. The inspectors also reviewed previous NCRs related to improper use of jumpers and walked down the control rod programmer instrumentation. Furthermore, the inspectors interviewed the RCA team leader.
b. Findings
Introduction:
A Green self-revealing NCV of Improved Technical Specification (ITS) 5.6.1.1.a was identified for the failure to follow the provisions of preventative maintenance procedure PM-126, Electrical Checks of CRD [Control Rod Drive] Power Train. Failure to follow PM-126 caused the failure of the Group 7 control rod programmer during maintenance and resulted in the unexpected insertion of the Group 7 control rods fully into the core. This unexpected insertion of these control rods into the core caused control room operations personnel to manually trip the reactor from 100 percent power.
Description:
On August 24, 2009, Unit 3 was operating at 100 percent power when the control room operators received multiple alarms and observed all eight of the Group 7 control rods fully insert into the reactor core. The reactor was manually tripped prior to automatic actuation of the reactor protection system (RPS).
The Group 7 control rods are the controlling group. They are expected to insert and withdraw in small increments corresponding to integrated control system (ICS) commands when the ICS is in Automatic. Movement of the rods is supervised by a programmer/controller (programmer) dedicated to Group 7. The unexpected drop of the Group 7 control rods was due to the failure of the programmer caused by inadvertent test jumper contact during performance of PM-126, using an improperly fused test jumper. These two conditions caused an over-current failure of the output driver within the Group 7 CRD programmer, which caused the unexpected insertion of the Group 7 control rods fully into the core. The licensee performed a root cause analysis of this event and concluded that the root cause was failure to follow the provisions of PM-126, Electrical Checks of CRD [Control Rod Drive] Power Train. PM-126 directs use of a fused jumper, with a current limit of 0.1 amp. The jumper fuse was checked and found to be a 1.0 amp fuse. This is not consistent with the procedure, and is not adequate to protect the associated equipment which has a maximum current rating of 0.5 amp. During performance of PM-126, the jumper made inadvertent contact with a positive voltage/current source, causing an over-current failure of the output driver within the Group 7 CRD programmer. This failure resulted in the unexpected insertion of the Group 7 rods fully into the core, and the associated manual reactor trip by control room operations personnel.
The inspectors reviewed the licensee root cause analysis contained in NCR 351705, Significant Adverse Condition Investigation Report. This report concluded that the root cause of this event was poor performance of a task by the individual in that the worker did not verify that the proper fuse was in the jumper. The report also concluded that contributing causes of this event were insufficient level of detail in the procedure and a poor work environment. The inspectors determined that the identified root and contributing causes were accurate as stated.
The inspectors also reviewed NCR 351744 which was generated as a result of Rod 7-5 indicating a slower drop response than the other rods in Group 7, and NCR 351741 which was generated as a result of pressure pulsations occurring in various condensate system lines following the manual reactor trip. No significant issues were identified by the inspectors during these reviews.
Analysis:
The licensee's failure to follow the provisions of PM-126, Electrical Checks of CRD [Control Rod Drive] Power Train, was a performance deficiency which resulted in a manual reactor trip. This finding was determined to be more than minor because it was associated with the initiating events cornerstone attribute of Human Performance, and adversely affected the cornerstone objective to limit the likelihood of those events that upset plant stability and challenge critical safety functions during at-power operations. The finding was evaluated using Phase 1 of the At-Power SDP, and was determined to be of very low safety significance (Green) because it did not contribute to both the likelihood of a reactor trip and the likelihood that mitigating equipment or functions were not available.
The cause of this finding was directly related to the cross-cutting area of Human Performance with a work practices aspect (H.4 (b)). Specifically, the workers failed to follow the preventative maintenance procedure.
Enforcement:
Crystal River Unit 3 Nuclear Plant Improved Technical Specifications, Section 5.6.1.1.a, states in part, "Written procedures shall be established, implemented, and maintained covering the following activities:
- (a) The applicable procedures recommended in Regulatory Guide 1.33, Revision 2, Appendix A, February 1978." Regulatory Guide 1.33, Revision 2, Appendix A, February 1978, Section 3(b) states "Instructions for energizing, filling, venting, draining, startup, shutdown, and changing modes of operation should be prepared, as appropriate, for the following systems: Control Rod Drive System (including part length rods)." Contrary to the above, the licensee failed to follow the provisions of PM-126, Electrical Checks of CRD [Control Rod Drive] Power Train. Failure to follow this procedure is a violation of Improved Technical Specifications. This failure resulted in a manual reactor trip. Because the finding is of very low safety significance and has been entered into the licensee's corrective action program as NCR 351705, this violation is being treated as an NCV consistent with Section VI.A.1 of the NRC Enforcement Policy: NCV 05000302/2009005-02, Manual Reactor Trip Due To Group 7 Control Rods Insertion Caused by Inadequately Protected Test Jumper.
4OA5 Other Activities
.1 Quarterly Resident Inspector Observations of Security Personnel Activities
a. Inspection Scope
During the inspection period, the inspectors conducted observations of security force personnel and activities to ensure that the activities were consistent with licensee security procedures and regulatory requirements relating to nuclear plant security. These observations took place during normal and off-normal plant working hours. These quarterly resident inspector observations of security force personnel and activities did not constitute any additional inspection samples. Rather, they were considered an integral part of the inspectors' normal plant status reviews and inspection activities.
b. Findings
No findings of significance were identified.
.2 Unit 3 Steam Generator Replacement Inspection (IP 50001)
a. Inspection Scope
Design and Planning The inspectors reviewed the following related to the licensee
=s steam generator replacement (SGR) project design and planning:
- scope and schedule
- engineering change (EC) packages
- 10 CFR Part 50.59 evaluation
- quality assurance program and corrective actions
- preparations for the creation of a temporary containment wall opening
- applicable engineering design, modification, and analysis associated with lifting, rigging, and transporting of the steam generators (SGs)
- radiation protection program controls, planning, and preparation
- security considerations associated with vital and protected area barriers affected by the SGR activities
- controls to minimize any adverse impact the activities may have had on other systems. The licensee used ASME Boiler and Pressure Vessel Code (ASME Code)Section III, 1998 Edition through 2000 Addenda, and Section XI, 2001 Edition through 2003 Addenda, for the design, fabrication, replacement, and installation of the new replacement SGs (RSGs) and systems. The licensee used ASME Code Section III for the design, fabrication, installation, and nondestructive examination (NDE) as the construction code for the following major component modifications: reactor cooling system (RCS) primary piping connections; main steam, feedwater, and emergency feedwater piping connections; and the steel containment vessel. The inspectors reviewed and examined the SGR activities and compared them to the requirements of the ASME Code.
The inspectors reviewed EC 63038, Replacement Once Through Steam Generators (ROTSGs or RSGs), for Crystal River Unit 3. EC 63038 included the design changes, analyses, evaluations, safety analyses, 10 CFR Part 50.59 change evaluation, configuration, materials, implementation, and post modification testing acceptance. The inspectors reviewed the following other major modification packages: EC 62500, RCS Hot Leg Cutting and Welding; EC 63016, Containment Opening; EC 63025, Main Feedwater Flow Accelerated Corrosion (FAC) Pipe Replacement; EC 63026, RCS Cold Leg Cutting and Welding; EC 63027, Secondary Side Large Bore Pipe Cutting and Welding; EC 63034, Structural Interferences; and EC 63039 Replacement Steam Generator Anchorage. The inspectors also reviewed other miscellaneous and temporary modifications.
The inspectors reviewed design calculations and analyses for design methods, assumptions, loadings, computations, and accuracies. The inspectors also selected work order (WO) packages prepared for the construction and implementation of the ECs for review to determine whether appropriate work processes and quality control hold points were implemented.
The inspectors reviewed the licensee's screening of selected ECs to determine whether the modifications were evaluated in accordance with 10 CFR Part 50.59, "Changes, tests, and experiments."
Removal and Replacement
The inspectors periodically reviewed radiation controls. The inspectors verified that the tendons were removed after plant shutdown and prior to the hydro demolition of concrete for the containment building wall opening located above the equipment hatch in order to transport the SGs out from or into the containment. The inspectors observed the hydro demolition process. The licensee identified some concrete cracks/separation issues. The concrete separations could be seen within the entire perimeter of the opening. An NRC Special Inspection Team (SIT) was formed to inspect the separation issues. The SIT's charter included review of the evaluation, root cause, and corrective actions to be implemented to ensure an operable containment structure. The SIT remained ongoing at the end of this inspection period. Results of the SIT will be documented in NRC special inspection report 05000302/2009007.
The inspectors reviewed the cracks or delamination found on the exposed concrete around the containment building wall opening during and after the hydro demolition. The licensee evaluated the containment wall cracks to modify the horizontal transfer system (HTS) supporting structures. Prior to the removal of the original or old SGs (OSGs), the inspectors reviewed, observed, and evaluated the associated temporary and permanent modifications of the cutting, disconnecting, and the providing of temporary supports for the OSGs and cutoff piping. The inspectors observed: lifting, rigging, downending and upending, and transporting of the OSGs, RSGs, and associated equipment; machining and preparations of the existing piping for the connections to the RSGs; welding and NDE activities; and the radiological safety plan for the temporary storage and disposal building of the retired steam generators. The inspectors reviewed and observed the major structural modifications. The inspectors observed the licensee performance inspection of the steam generator hold down bolts to make sure that the bolts were acceptable to hold down the RSGs after the OSGs were moved out from the cubicles. During the SG removal and replacement, the inspectors observed licensee activities associated with controls for excluding foreign material, including the primary and secondary side of the steam generators and in the related RCS openings, and the establishment of operating conditions including defueling, RCS draindown and system isolation. The inspectors reviewed and inspected the status of security activities associated with vital and protected area plant and equipment changes required for the transportation of the OSGs and RSGs. The inspectors reviewed the installation, use, and removal of temporary services directly related to the steam generator replacement activities.
The inspectors observed and reviewed selected welding, NDE, preservice inspections, baseline inspections, and corrective action activities for the Class 1 and 2 piping and components of the RSGs.
The inspectors reviewed procedures, examination results, modification packages, and work order packages related to the modifications, including the construction hatch steel containment vessel (SCV) reinstallation, to ensure compliance with the requirements of the ASME Code.
This inspection remained ongoing at the end of this inspection period because the closure of the containment wall opening was not completed due to the cracks/delamination identified in the containment wall.
RSG Fabrication, Preservice Inspection, and Baseline Inspection The inspectors reviewed records associated with the materials, fabrication, examination, and testing for the RSGs manufactured by Babcock & Wilcox Canada (BWC), and replacement hot leg piping subassemblies ("Candy Canes"), to verify compliance with the ASME Code.

The inspectors also walked down one RSG while stored on site, prior to movement into containment.
The inspectors reviewed documentation and interviewed plant personnel regarding the preservice and baseline testing of RSG tubing. All preservice inspection (PSI) or baseline inspection (BI) using eddy current testing (ECT) for the RSG tubes was completed off-site by BWC in Cambridge, Ontario, Canada. Full length 100 percent bobbin inspections were performed, and 100 percent X-probe data was acquired, but only analyzed in areas of interest. Profilometry data was also collected in the tubesheet expansion region. The inspectors reviewed the licensee's degradation assessment, BWC ECT PSI report, ECT acquisition procedures, examination technique specification sheets, and data analysis procedures. In addition, the inspectors reviewed documentation regarding the manufacture of the RSG tubing by Sumitomo in Japan including heat treatment records and nonconformance reports.
The inspectors reviewed records and conducted interviews with plant personnel associated with the fabrication of the replacement hot leg piping subassemblies. Documents reviewed included the ASME Data Report, corrective action documents, the vendor ASME Certificate of Authorization, a self-assessment report, and the engineering change package. The inspectors also walked down both replacement hot leg piping subassemblies while stored on site, prior to movement into containment.
Welding: The inspectors reviewed a sample of welding activities associated with the installation of the RSGs to evaluate compliance with licensee/contractor procedures and the applicable ASME Code. The inspectors reviewed joint configuration drawings, welding procedures, welding specifications, welding procedure qualifications, welder qualification records, weld data records, nuclear condition reports (NCRs), and post weld heat treatment procedures (where applicable) for the welds listed below.
- MS-00-024, SG A Main Steam East Elbow-to-Pipe
- MS-00-034, SG A Main Steam West Elbow-to-Pipe In addition to the record review described above, the inspectors performed field observations either via video monitors located outside containment or by direct observation inside containment of the machine welding of the RCS hot leg and cold leg piping welds listed below.

- MS-00-045, SG B Main Steam East Pipe-to-Pipe Containment Construction Hatch Opening and Closure - Steel and Concrete Containment The inspectors reviewed the licensee
=s activities associated with the concrete removal and the removal and restoration of the steel containment liner plate (SCLP) for the containment construction hatch opening, as detailed in the EC 63016, Containment Opening.
The inspectors reviewed the plans for the cutting and restoration of the SCLP for the construction hatch opening and compared post testing requirements to the applicable ASME Code. The inspectors observed the hydraulic cutting, hydro demolition, of concrete for the containment construction hatch opening and reviewed the work order packages for the cutting to verify the steps had been completed and documented.
The inspectors reviewed the welding procedures, procedure qualification records, and welder qualification records to confirm that the Code-required essential and supplemental essential welding variables were met. The inspectors reviewed the work order package including welding electrode receipt inspection, vacuum box leak testing, MT records, material certification records, and qualification and certification records for NDE personnel, equipment, and consumables.
The inspectors reviewed the containment wall delamination that was found next to the Hoop or Horizontal Tendons about 10 inches from the outside surface of the containment wall. The delamination was identified on the exposed concrete wall surfaces around the opening of containment during and after the hydro demolition for the opening. The inspectors observed the licensee perform ultrasonic impulse response and impact echo examinations as NDE methods to detect and scope the delamination areas.
The licensee planned to address the closure of the containment wall opening as part of the repair of the containment wall delamination.
Heavy Load, Rigging, Lifting, and Transporting Activities The inspectors reviewed Progress Energy maintenance procedures MNT-NGGC-0005, Control of Rigging and Temporary Loads, Revision 3 and MNT-NGGC-0021, Lifting and Rigging Practices and Equipment, Revision 0. The inspectors reviewed the SG lifting preparation activities as described in the following EC Packages and lifting equipment load test data to ensure that they were prepared in accordance with regulatory requirements, appropriate industrial codes and standards, and to verify that the maximum anticipated loads to be lifted would not exceed the capacity of the lifting equipment and supporting structures: EC 63020, Outside Erection Crane and Inside Auxiliary Crane, Revision 7; EC 63022, Steam Generator Rigging and Transport including the Outside Lift System (OLS), Hatch Transfer System (HTS), and Temporary Lifting Device (TLD), Revision 31; and EC 63023, OSG/RSG Haul Route, Revision 3.
The inspectors examined SGR project lifting, rigging, and transporting equipment including the polar crane, mobile crane, TLD, HTS including skid system, the down/up-ender device, OLS, and the self-propelled modular transporter (SPMT). The inspectors observed portions of rigging, lifting, transportation, and positioning of the original and replacement SGs.
The inspectors reviewed procedures, calculations, drawings, work packages, crane and equipment operator training and certificates, and load and function test records to determine whether they were in accordance with regulatory requirements and appropriate industrial codes and standards. The inspectors also reviewed polar crane and containerized winch system inspection and maintenance records.
The inspectors reviewed the licensee's analyses for buried piping located beneath the transport path as documented in Calculation S06-0019, Evaluation of Buried Utilities under Haul Route, Revision 0. The inspectors also reviewed calculations related to heavy load lifting systems, including: S06-0009, TLD Loads on Polar Crane Rail, Revision 0; S06-0012, Outside Lifting System East Foundation Design, Revision 3; and S06-0015, Seawater Room Wall Evaluation, Revision 1.
Quality Assurance (QA) Program and Corrective Actions
The inspectors conducted a review of the quality assurance program and its implementation for the SG replacement to assess compliance with the requirements of 10 CFR Part 50, Appendix B. The inspectors reviewed daily quality summaries, quarterly reports, QA audit procedures, audit reports, and QA personnel certifications, and conducted interviews with QA and quality control (QC) personnel.
The inspectors reviewed the surveillance reports and nonconformance reports issued for the root cause analyses, evaluations, repairs, or disposition during the manufacturing of the RSGs. The inspectors also selected the NCRs and Audit Reports for review during the implementation of the removal and reinstallation of the SGs. The review was to ensure that issues were being identified appropriately, entered into the corrective action program (CAP) correctly, and dispositioned adequately. The inspectors also reviewed procedures associated with the training of personnel for the identification, disposition, and documentation of the NCRs.
Post Installation Verification and Testing
The inspectors reviewed the post installation verification and testing program to verify that the required post installation verification and testing, procedural changes, and the adjustment of the instruments were properly identified. The inspectors verified that the modifications were completed in accordance with the design documents and reviewed the required post modification tests.
The inspectors reviewed the work packages to verify that the required NDE and preservice inspections were completed as designed and met code requirements for the major modifications of the SGs, structures, and piping.
The post modification or installation verification and testing related to RCS leakage testing, containment pressure leak testing, SG thermal and hydraulic performance testing, other instrument setting or testing were not completed during this quarter because the installation of the containment construction hatch opening closure and the repair of the containment wall delamination was delayed to the next year. Additionally, steam generator secondary side leakage testing had not been completed by the licensee at the conclusion of this inspection period.
All documents reviewed for IP 50001 are listed in the attachment to this report.
b. Findings
No findings of significance were identified.
.3 Steam Generator Replacement Inspection (Radiation Protection Activities)
a. Inspection Scope
The inspectors reviewed and evaluated ALARA planning and implementation of radiological controls for current SG removal/replacement, transport, and onsite storage activities Radiation, contamination, and airborne radioactivity surveys were reviewed to evaluate 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 radiation protection and ALARA staff. The inspectors also reviewed plans and dose estimates for on-site storage of the old SGs and associated piping. Individual worker doses and project dose expenditures for the SG removal/replacement project activities were reviewed and discussed in detail with licensee representatives.
Initial administrative and physical controls associated with the SGs and associated piping prior to their removal from containment and subsequent to their placement in the onsite storage facility were observed and evaluated. The inspectors evaluated implementation of selected radiological controls including worker briefings, postings, shielding, and air monitoring associated with removal of the old SGs from containment. The inspectors also toured the onsite temporary storage facility and conducted independent radiological surveys of the onsite storage facility subsequent to placement of the SG components into the facility. In addition, the inspectors discussed on-going radiological controls and surveillances associated with the onsite storage facility.
The SG removal and replacement activities were evaluated against 10 CFR Parts 19 and 20, and approved licensee design documents and applicable procedures. Licensee guidance documents, records, and data reviewed within this inspection area are listed in Sections 2OS1, 2OS2, and
4OA1 of the attachment.

4OA6 Meetings, Including Exit
Exit Meeting Summary
On January 11, 2010, the resident inspectors presented the inspection results to Mr. J. Franke, Site Vice President, and other members of licensee management. The inspectors confirmed that proprietary information was not provided or examined during the inspection.
4OA7 Licensee Identified Violations
The following issue of very low safety significance (Green) was identified by the licensee and was a violation of NRC requirements. This issue met the criteria of Section VI of the NRC Enforcement Policy, NUREG-1600, for being dispositioned as a Non-Cited Violation.
10 CFR 26.205(d) requires, in part, that individuals subject to work hour controls do not exceed 26 work hours in any 48-hour period and 72 work hours in any 7-day period; requires a 34-hour break in any 9-day period; and a 10-hour break between successive work periods. During the period of October 12 to October 19, 2009, one worker exceeded 26 hours3.009259e-4 days <br />0.00722 hours <br />4.298942e-5 weeks <br />9.893e-6 months <br /> in a 48-hour period; nine workers exceeded 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> in a 7-day period; five workers did not have a 34-hour break in a 9-day period; and two workers did not have the required 10-hour break between successive work periods. The violation was limited to one work group, Florida Transmission Personnel, who were on-site to support outage work. The licensee determined that the Transmission personnel did not have a firm understanding of the revised 10 CFR Part 26 requirements. The finding was more than minor because, if left uncorrected, it would become a more significant safety concern. Specifically, the excessive work hours would increase the likelihood of human performance errors during plant maintenance activities that could affect equipment performance. The finding is of very low safety significance because no significant events or human performance issues were directly linked to personnel fatigue as a result of the hours worked. This issue was documented in the licensee's corrective action program as NCR 361777.
