A finding of very low safety significance and an associated NCV of 10 CFR Part 50, Appendix B, Criterion V, Instructions, Procedures and Drawings, was identified by the NRC inspectors. Specifically, the licensee failed to perform dimensional testing of the reactor pressure vessel head strongback and the steam dryer/steam separator lifting device required by American National Standards Institute (ANSI) N14.6-1978. In addition, the license failed to perform nondestructive testing of steam dryer/steam separator lifting device major load carrying welds and critical areas required by ANSI N14.6-1978. These issues were entered into the licensees corrective action program. | |||
The finding was determined to be more than minor because the finding was associated with the Initiating Events Cornerstone objective to limit the likelihood of events that upset plant stability and challenge critical safety functions during shutdown. Specifically, the purpose of the dimensional testing of reactor pressure vessel head strongback and steam dryer/steam separator lifting device and nondestructive testing of the steam dryer/steam separator lifting device major load carrying welds and critical areas is to limit the likelihood of a reactor pressure vessel head strongback or steam dryer/steam separator lifting device structural component failure, and hence, to ensure safe load handling of heavy loads over the reactor core or over safety-related systems, structures and components. The inspectors determined the finding was of very low safety significance following a qualitative significance determination process review performed by the Region III Senior Risk Analyst. The inspector did not identify a cross-cutting aspect associated with this finding because the concern was related to licensing basis established in the 1980s, and thus was not necessarily indicative of current licensee performance.

Criteria V, Instructions, Procedures, and Drawings, was identified by the NRC inspectors. Specifically, the licensee failed to perform a required comprehensive pump test for division 1 and 2 emergency equipment cooling water makeup pumps within years of the start of the third inservice testing interval. The third inservice testing interval commenced on February 17, 2010, and included a requirement to perform a comprehensive pump test for the division 1 and 2 emergency equipment cooling water makeup pumps within two years and every two years thereafter. The required comprehensive pump tests were not performed prior to February 17, 2012. | |||
The finding was determined to be more than minor because the finding was associated with the configuration control attribute of the Mitigating Systems Cornerstone and impacted the cornerstone objective of ensuring the capability of systems to prevent undesirable consequences (i.e., core damage). This finding was determined to be of very low safety significance because, following IMC 0609, Appendix E, Table 4a, | |||

===Summary of Plant Status=== | |||
Fermi Unit 2 started this inspection period shutdown, continuing forced outage 12-02 which commenced with the catastrophic failure of the south reactor feed pump turbine on June 25, 2012. The Unit remained shut down until July 22, 2012. The Unit increased power to 2 percent and returned to a shutdown condition to repair a valve motor. The Unit restarted on July 27, 2012, and achieved 68 percent power on July 30, 2012, using one main feedwater pump. The Unit maintained 68 percent power until September 14, 2012, when the Unit scrammed due to a fault in the 120 kV switchyard. The Unit commenced startup on September 19, 2012, achieved 68 percent power on September 20, 2012, and remained there for the remainder of the inspection period. | |||

===.1 External Flooding=== | |||
====a. Inspection Scope==== | |||
The inspectors evaluated the design, material condition, and procedures for coping with the design basis probable maximum flood. The evaluation included a review to check for deviations from the descriptions provided in the Updated Final Safety Analysis Report (UFSAR) for features intended to mitigate the potential for flooding from external factors. | |||
As part of this evaluation, the inspectors checked for obstructions that could prevent draining, checked that the roofs did not contain obvious loose items that could clog drains in the event of heavy precipitation, and determined that barriers required to mitigate the flood were in place and operable. Additionally, the inspectors performed a walkdown of the protected area to identify any modification to the site which would inhibit site drainage during a probable maximum precipitation event or allow water ingress past a barrier. The inspectors also walked down underground bunkers/manholes subject to flooding that contained multiple train or multiple function risk-significant cables. The inspectors also reviewed the abnormal operating procedure for mitigating the design basis flood to ensure it could be implemented as written. | |||

The inspectors performed partial system walkdowns of the following risk-significant systems: | |||
* Mechanical isolation of main steam to the south reactor feed pump/turbine (RFPT) for Engineering Design Package (EDP) -36982; | |||
* residual heal removal (RHR) system shutdown cooling during the forced outage; and | |||
* high pressure coolant injection (HPCI). | |||
The inspectors selected these systems based on their risk significance relative to the Reactor Safety Cornerstones at the time they were inspected. The inspectors attempted to identify any discrepancies that could impact the function of the system and, therefore, potentially increase risk. The inspectors reviewed applicable operating procedures, system diagrams, UFSAR, Technical Specification (TS) requirements, outstanding work orders (WOs), condition reports, and the impact of ongoing work activities on redundant trains of equipment in order to identify conditions that could have rendered the systems incapable of performing their intended functions. The inspectors also walked down accessible portions of the systems to verify system components and support equipment were aligned correctly and operable. The inspectors examined the material condition of the components and observed operating parameters of equipment to verify there were no obvious deficiencies. The inspectors also verified the licensee had properly identified and resolved equipment alignment problems that could cause initiating events or impact the capability of mitigating systems or barriers and entered them into the corrective action program with the appropriate significance characterization. Documents reviewed are listed in the Attachment to this report. | The inspectors selected these systems based on their risk significance relative to the Reactor Safety Cornerstones at the time they were inspected.

The inspectors selected these potential operability issues based on the risk significance of the associated components and systems. The inspectors evaluated the technical adequacy of the evaluations to ensure TS operability was properly justified and the subject component or system remained available such that no unrecognized increase in risk occurred. The inspectors compared the operability and design criteria in the appropriate sections of the TSs and UFSAR to the licensees evaluations to determine whether the components or systems were operable. Where compensatory measures were required to maintain operability, the inspectors determined whether the measures in place would function as intended and were properly controlled. The inspectors determined, where appropriate, compliance with bounding limitations associated with the evaluations. Additionally, the inspectors reviewed a sampling of corrective action documents to verify the licensee was identifying and correcting any deficiencies associated with operability evaluations.

====b. Findings==== | |||
1) Inspection Procedure for Reactor Pressure Vessel Head Strongback and Steam Dryer/Steam Separator Lifting Device Omitted Dimensional Testing and Nondestructive Testing Requirements | |||
=====Introduction:===== | |||
The inspectors identified a finding of very low safety significance (Green) and an associated NCV of 10 CFR Part 50, Appendix B, Criterion V, Instructions, Procedures, and Drawings, in that, the procedure used to demonstrate compliance with ANSI N14.6-1978, Standard for Special Lifting Devices for Shipping Containers Weighing 10,000 pounds (4500 kg) or More for Nuclear Materials, Section 5.3.1, provisions did not include dimensional testing of reactor pressure vessel (RPV) head strongback and steam dryer/steam separator lifting device. In addition, several major load carrying welds and critical areas of steam dryer/steam separator lifting device were not being nondestructively tested in accordance with the provisions specified in ANSI N14.6-1978. As a result, the licensee used the RPV head strongback and steam dryer/steam separator lifting device during each refueling outage without performing dimensional testing of RPV head strongback and steam dryer/steam separator lifting device and without performing nondestructive testing of major load carrying welds and critical areas of the steam dryer/steam separator lifting device. | |||
=====Description:===== | |||
Section 3.2-1 of the UFSAR, classified both the RPV head strongback and steam dryer/steam separator lifting device as having quality assurance requirements in accordance with 10 CFR Part 50 Appendix B. Section 9.1.4.4 of the UFSAR states in part, "The special lifting devices at Fermi 2 are the reactor pressure vessel head strongback and the dryer/steam separator lifting device. Periodic testing of these special lifting devices meets the guidelines of NUREG-0612, Control of Heavy Loads at Nuclear Power Plants, by following ANSI N14.6-1978. Section 5.3.1 of ANSI N14.6-1978 requires each special lifting device be subjected to either a load test or dimensional testing, visual inspection, and nondestructive testing of major load carrying welds and critical areas. The licensee implemented the second option and hence did not perform a load test of the RPV head strongback and steam dryer/steam separator lifting device. | |||
Preventative Maintenance Activity No. F130, Perform NDE on Special Lifting Device identified the only major load carrying welds for the steam dryer/separator lifting device as part of detail A of Fermi Drawing 6C721-2201, Design and Details of Dryer/Separator Lifting Device, Revision B. The inspectors noted that Calculation DC-3266, Design Check for Rigging Apparatus, Revision A, evaluated the design adequacy of the major load carrying welds on the steam dryer/steam separator lifting device. In addition to detail A, Calculation DC-3266 identified the major load carrying welds were also part of Section 1 and socket box detail of Drawing 6C721-2201. The licensee agreed Section 1 and socket box detail of Drawing 6C721-2201 were major load carrying welds as well. The inspectors also determined that Procedure 32.RIG.018, Guidelines and Practices for the Use of Hoisting and Rigging Equipment, Revision 8, did not include the ANSI N14.6-1978 requirement to perform dimensional testing of the RPV head strongback and steam dryer/steam separator lifting device. The licensee could not produce documentation to verify nondestructive testing of load carrying welds associated with Section 1 and socket box detail of Drawing 6C721-2201 welds were performed as well as dimensional testing of both the strongback and the lifting device. In response to these concerns, the licensee initiated CARD 12-27537, NRC Identified NDE Inspections, dated September 12, 2012, to address these concerns. | |||

-1978 | |||
===== | =====Analysis:===== | ||
The inspectors determined the failure to perform dimensional testing of RPV head strongback and steam dryer/steam separator lifting device and nondestructive testing of several of the steam dryer/steam separator lifting device major load carrying welds and critical areas was contrary to the ANSI N14.6-1978 provisions and was a performance deficiency. The finding was determined to be more than minor in accordance with IMC 0612, Appendix B, Issue and Screening, Minor Question 4, because the finding was associated with the Initiating Events Cornerstone attribute of equipment performance and affected the cornerstone objective to limit the likelihood of those events that upset plant stability and challenge critical safety functions during shutdown. Specifically, the purpose of the dimensional testing and nondestructive testing of RPV head strongback and steam dryer/steam separator lifting device is to limit the likelihood of a structural component failure, hence, ensuring safe load handling of heavy loads over the reactor core or over safety-related systems. | |||
- | |||
The inspectors determined the finding could be evaluated using IMC 0609, Appendix A, The Significance Determination Process (SDP) for Findings At-Power, Exhibit 1, for the Initiating Events Cornerstone. The inspectors determined the finding would be related to a transient initiator, which could cause a reactor trip and loss of mitigation equipment. | |||
-Power, | |||
Therefore, the Region III senior reactor analyst (SRA) performed a more detailed risk evaluation. Since the plant would be shutdown when the RPV head strongback or steam dryer/steam separator lifting device was used, the RIII SRA conducted the assessment of the risk significance using IMC 0609, Appendix G, Shutdown Operations SDP. Table 1 of Appendix G, Losses of Control, does not apply since no event occurred. The SRA reviewed Appendix G, Attachment 1, Shutdown Operations SDP, Phase I Operational Checklists for Both Pressurized Water Reactors (PWRs) and Boiling Water Reactors (BWRs). The applicable checklist was Checklist 6, BWR Cold Shutdown or Refueling Operation - Time to Boil < 2 hours: Reactor Coolant System level < 23' Above Top of Flange. The applicable safety functions impacted were decay heat removal and inventory control. The SRA continued the risk-evaluation with a Phase II SDP assessment. | |||
The SRA reviewed Appendix G, Attachment 3, | The SRA reviewed Appendix G, Attachment 3, Phase II Significance Determination Process Template for BWR during Shutdown. In Phase II, the most limiting plant operating state was POS-1 with an early time window. The SRA evaluated the impact of the performance deficiency on the loss of decay heat (i.e., loss of residual heat removal (LORHR)) and loss of inventory initiators in Appendix G. Both initiators were representative of condition findings as defined in Appendix G, Attachment 3. | ||

For each initiator, the estimated initiating event likelihood (IEL) was 3E | For each initiator, the estimated initiating event likelihood (IEL) was 3E-4/yr. The licensee provided data from Fermi's past two refueling outages that showed the RPV head strongback and steam dryer/steam separator lifting device are used to move a very heavy load a combined eight times per refuel outage (for approximately 10 hours per outage). At Fermi refuel outages are held every 18 months. Based on this, the number of lifts over a 12-month period was computed to be 5.3 lifts. The SRA also used information in NUREG 1774, A Survey of Crane Operating Experience at U.S. Nuclear Power Plants from 1968 through 2002, to obtain an estimate of failure probability of the RPV head strongback and steam dryer/steam separator lifting device. Based on actual crane operating experience data from Commercial U.S. Nuclear Power Plants, this NUREG estimated the probability of load drops per demand for very heavy loads to be 5.6E-05. Thus the IEL of 3E-4/yr was estimated based on 5.3 lifts per year with a failure probability of 5.6E-5 per lift. The SRA noted the licensee visually inspected the strongback and lifting device prior to each use and performed limited nondestructive examination every five years with no deficiencies identified, so this IEL may be conservative for Fermi. | ||

In response to this concern, the licensee initiated CARD 12-27276, NRC Identified-Revise Calculation DC-3266, Volume I, dated August 31, 2012, to address these concerns. | |||
The inspectors determined the | =====Analysis:===== | ||
The inspectors determined the failure to meet the Section 3.2.1 design provisions of ANSI N14.6 for the steam dryer/steam separator lifting device was a performance deficiency. | |||
The finding was determined to be more than minor in accordance with IMC 0612, Appendix B, Issue and Screening, Minor Question 4, because the finding was associated with the Initiating Events Cornerstone attribute of design control and affected the cornerstone objective to limit the likelihood of those events that upset plant stability and challenge critical safety functions during shutdown. Specifically, the purpose of the lifting device design requirements was to limit the likelihood of a structural component failure, and hence, to ensure safe load handling of heavy loads over the reactor core or over safety-related systems. | |||
The inspector did not identify a cross | The inspectors determined the finding could be evaluated using IMC 0609, Appendix A, The SDP for Findings At-Power, Exhibit 1, for the Initiating Events Cornerstone. The inspectors determined the finding would be related to a transient initiator which could cause a reactor trip and loss of mitigation equipment. Therefore, the Region III SRA performed a more detailed risk evaluation. The Region III SRA determined the risk significance documented in Section 1R20.2.b.1) of this report applies to this finding as well. As stated in Section 1R20.2.b.1), the SRA determined the risk of the finding to be of very low safety significance (Green). The inspector did not identify a cross-cutting aspect associated with this finding because the concern was related to a calculation from the 1980s, and thus was not necessarily indicative of current licensee performance. | ||
-cutting aspect associated with this finding because the concern was related to a calculation from the 1980s, and thus was not necessarily indicative of current licensee performance. | |||
=====Enforcement:===== | |||
Title 10 CFR Part 50, Appendix B, Criterion III, Design Control, states, in part, that the design control measures shall provide for verifying or checking the adequacy of design, such as by the performance of design reviews, by the use of alternate or simplified calculation methods, or by the performance of a suitable testing program. | |||
Contrary to the above, on August 31, 2012, the inspectors determined that for Calculation DC-3266 the licensees design control measures failed to ensure adequacy of the design. Specifically, this calculation did not conform to and was nonconservative with respect to ANSI N14.6 provisions. | |||
Because this violation was of very low safety significance (Green) and it was entered into the licensees corrective action program as CARD 12-27276, this violation is being treated as an NCV, consistent with Section 2.3.2 of the NRC Enforcement Policy. | |||

On May 16, 2012, procedure 54.000.20, | On May 16, 2012, procedure 54.000.20, Reactor recirculation system MG (RRMG) set scoop tube positioner operability test, was performed to set mechanical, electrical, and distributed control system (DCS) stops for both the A and the B RRMG sets. Both RRMG set speeds and core flow were varied to collect data, establish a least squares fit of the data, and then extrapolate the data to establish the mechanical, electrical and DCS set points. On May 17, 2012, the residents reviewed a copy of the completed procedure and noted the extrapolated data points did not fall upon the least squares fit regression line. The resident identified this discrepancy to the reactor engineering supervisor. | ||
Discussion: | Discussion: On May 16, 2012, procedure 54.000.20, Reactor recirculation system MG set scoop tube positioner operability test, was performed to set mechanical, electrical, and DCS stops for both the A and the B RRMG sets. Both RRMG set speeds and core flow were varied to collect data. Procedure 54.000.20 requires the data collected in attachment 1 (i.e., by varying core flow and RRMG set speeds) to be plotted on a graph and extrapolated to determine the mechanical, electrical and DCS setpoints. | ||

Conclusions: | Further, the residents reviewed the completed procedure 54.000.20 archived in the licensees document management system. This procedure and work order had a designated review by reactor engineering required following the performance of the procedure. The residents were advised that the reactor engineering reviewer was knowledgeable of the issues raised in CARD 12-24565; however, there was no documentation provided of the deficiencies in setting the mechanical high speed stops, electrical stops, or DCS high speed limits, and no listing of CARD 12-24565 provided by the reviewer. | ||
Conclusions: Incorrectly setting the RRMG set mechanical stops was a near miss to a Technical Requirements Manual violation. Additionally, failing to validate the data collected and extrapolated to establish the mechanical, electrical, and DCS stops was a fundamental engineering process weakness, which resulted in a human performance departmental reset. Finally, designated reviewers should critically identify deficiencies identified during the review process. This provides more complete documentation of issues and concerns, (i.e., including known deficiencies for archival purposes). | |||

On February 17, 2010, Fermi 2 commenced their third IST interval. The IST program owner identified a requirement to perform a CPT for the division 1 and 2 EECW makeup pumps. The IST program owner reviewed the Operations and Maintenance (OM) Code and determined the CPT required testing the EECW makeup pumps at or near their best efficiency point. This required a significant operation or evolution (SOE) to perform the initial CPT to utilize as the baseline data, and the CPT would then be performed every two years thereafter.

Although not issued until after the February 16, 2012, due date of this surveillance, Enforcement Guidance Memorandum (EGM) 12-001, issued February 24, 2012, provides enforcement discretion to TS Section 5.0, since the revision to the standard TSs to make the provisions of SR 3.0.2 (and SR 3.0.3) applicable also made the Section 3.0, Surveillance requirement applicability, applicable to the TS Section 5.0. The result was that applying the standard TS rules of usage would prohibit licensees from using the SR 3.0.2 (and 3.0.3) allowances for TS Section 5.0. The EGM further points out the OM Code does not make available test allowances similar to either SR 3.0.2 (or SR 3.0.3)under 10 CFR 50.55a(f). Note, the OM Code committee has recently developed a code case which models SR 3.0.2 to make available up to an additional 25 percent of the test frequency. As yet, however, the code case has neither been approved and issued by the ASME nor endorsed by the NRC. In this situation there is no evidence the IST program owner evaluated the provisions and limitations of SR 3.0.2 and applied them to the required EECW makeup pump CPT SOEs. Therefore, the provisions of EGM 12-001 do not appear to apply. | |||

As a corrective action, for cycle 15 the licensee increased the frequency of performing TS surveillance 3.1.4.2 scram time testing to every 100 days, adjusted the representative sample size to assure all rods would be tested during cycle 15, and included control rod 10-35 in each quarterly scram time testing sample. | ||

Step 61 of STR 2012-001122 had connected a ground truck in bus 65E position E4 and installed a red danger tag. The ground truck was installed to perform work on bus 65E and load shedding string. The ground truck was not removed prior to energizing the bus. The breaker installed in bus 65E position E9 immediately tripped due to a fault and as a result of the electrical transient, the A RHR pump tripped while operating in shutdown cooling mode with the plant in Mode 5 for RFO-15. The pump trip was caused by an isolation of the division 1 RHR shutdown cooling inboard isolation valve E1150F009. A self-revealed Green finding and associated NCV of 10 CFR 50 Appendix B, Section V, Instructions, Procedures, and Drawings, was identified for this event and included in Inspection Report 05000341/2012003, section 4OA3.

Pressure Vessel Hydrostatic Test On April 26, 2012, surveillance procedure 24.137.21, Reactor Pressure Vessel System Leakage Test was in progress with the plant operating in Mode 4 (Cold Shutdown). All control rods were inserted. The surveillance was classified as an infrequently performed test or evolution, because of the safety significance of the testing and since the test is performed only once per cycle. Control rod scram time testing and excess flow check valve testing were also in progress, as allowed by the precautions and limitations of the RPV system leakage test procedure. | |||
A dedicated pressure control operator was assigned to maintain RPV pressure in the band of 1030 to 1055 psig as specified by the RPV system leakage test procedure. | |||
Pressure was controlled by using a combination of reactor water cleanup blowdown and control rod drive system flow adjustments. The dedicated pressure control operator selected a process computer point to display on a highly visible screen near the pressure control station. The selected point, B21CP6601, was displaying a reactor pressure average using two inputs. Due to ongoing excess flow check valve testing, one input to the average reactor pressure computer point became invalid as its instruments were removed from service prescribed by the excess flow check valve test. As a result, RPV pressure as seen by the process computer point, B21CP6601, lowered as isolated instruments slowly bled down (i.e., relieved pressure). Based on this false indication, the dedicated pressure control operator informed the control room supervisor that RPV pressure was lowering. At this time, actual reactor pressure was slowly rising. No adjustments were made based on these indications; and after approximately three minutes, RPV pressure reached the high pressure scram setpoint (1093 psig) causing a reactor scram. A self-revealed Green finding and associated NCV of TS 5.4.1.a for the licensees failure to establish and implement procedures recommended by Regulatory Guide 1.33, was identified for this event and included in Inspection Report 05000341/2012003, section 4OA3.

After completing repairs to main unit transformer 2B, reactor power was raised to approximately 22 percent and the unit was synchronized to the power grid. Shortly after operations began to increase power, multiple vibration-related alarms were received for the south reactor feed pump, and the pump tripped. The south reactor feed pump had catastrophically failed and as a result, condenser vacuum was decreasing. Operations performed a manual scram by taking the mode selector switch to shutdown.

SUBJECT:
FERMI POWER PLANT, UNIT 2, INTEGRATED INSPECTION REPORT 05000341/2012004
Dear Mr. Plona:
On September 30, 2012, the U.S. Nuclear Regulatory Commission (NRC) completed an integrated inspection at your Fermi Power Plant, Unit 2. The enclosed inspection report documents the inspection results which were discussed on October 11, 2012, with Mr. J. T. Conner, Site Vice-President, and other members of your staff.
The inspection examined activities conducted under your license as they relate to safety and compliance with the Commissions rules and regulations and with the conditions of your license.
The inspectors reviewed selected procedures and records, observed activities, and interviewed personnel.
Based on the results of this inspection, one self-revealed and three NRC-identified findings of very low safety significance were identified. The findings involved violations of NRC requirements. Additionally, a licensee identified violation is listed in Section 4OA7 of this report.
However, because of their very low safety significance, and because the issues were entered into your corrective action program, the NRC is treating the issues as non-cited violations (NCVs) in accordance with Section 2.3.2 of the NRC Enforcement Policy.
If you contest any of these 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 U.S. Nuclear Regulatory Commission, ATTN: Document Control Desk, Washington, DC 20555-0001, with a copy to the Regional Administrator, U.S. Nuclear Regulatory Commission - Region III, 2443 Warrenville Road, Suite 210, Lisle, IL 60532-4352; the Director, Office of Enforcement, U.S. Nuclear Regulatory Commission, Washington, DC 20555-0001; and the Resident Inspector Office at the Fermi Power Plant. If you disagree with the cross-cutting aspect assigned to any finding in this report, you should provide a response within 30 days of the date of this inspection report, with the basis for your disagreement, to the Regional Administrator, Region III, and the NRC Resident Inspector at the Fermi Power Plant. In accordance with 10 CFR 2.390 of the NRC's "Rules of Practice," a copy of this letter, its enclosure, and your response (if any) will be available electronically for public inspection in the NRC Public Document Room or from the Publicly Available Records System (PARS)
component of NRC's Agencywide Document Access and Management System (ADAMS).

SUMMARY OF FINDINGS
Inspection Report 05000341/2012004; 07/01/2012 - 09/30/2012; Fermi Power Plant, Unit 2;
Outage Activities, Identification and Resolution of Problems.
This report covers a 3-month period of inspection by resident inspectors and announced baseline inspections by regional inspectors. One self-revealed and three NRC-identified findings of very low safety significance (Green) were identified. The findings were considered non-cited violations (NCVs) of NRC regulations. The significance of most findings is indicated by their color (Green, White, Yellow, Red) using Inspection Manual Chapter (IMC) 0609,
Significance Determination Process (SDP). Cross-cutting aspects were determined using IMC 0310, Components within the Cross Cutting Areas. Findings for which the SDP does not apply may be Green or be assigned a severity level after NRC management review. The NRCs program for overseeing the safe operation of commercial nuclear power reactors is described in NUREG-1649, Reactor Oversight Process, Revision 4, dated December 2006.
NRC-Identified
and Self-Revealed Findings
Cornerstone: Initiating Events
- Green.
A finding of very low safety significance and an associated NCV of 10 CFR Part 50, Appendix B, Criterion V, Instructions, Procedures and Drawings, was identified by the NRC inspectors. Specifically, the licensee failed to perform dimensional testing of the reactor pressure vessel head strongback and the steam dryer/steam separator lifting device required by American National Standards Institute (ANSI) N14.6-1978. In addition, the license failed to perform nondestructive testing of steam dryer/steam separator lifting device major load carrying welds and critical areas required by ANSI N14.6-1978. These issues were entered into the licensees corrective action program.
The finding was determined to be more than minor because the finding was associated with the Initiating Events Cornerstone objective to limit the likelihood of events that upset plant stability and challenge critical safety functions during shutdown. Specifically, the purpose of the dimensional testing of reactor pressure vessel head strongback and steam dryer/steam separator lifting device and nondestructive testing of the steam dryer/steam separator lifting device major load carrying welds and critical areas is to limit the likelihood of a reactor pressure vessel head strongback or steam dryer/steam separator lifting device structural component failure, and hence, to ensure safe load handling of heavy loads over the reactor core or over safety-related systems, structures and components. The inspectors determined the finding was of very low safety significance following a qualitative significance determination process review performed by the Region III Senior Risk Analyst. The inspector did not identify a cross-cutting aspect associated with this finding because the concern was related to licensing basis established in the 1980s, and thus was not necessarily indicative of current licensee performance. (Section 1R20)
- Green.
A finding of very low safety significance and an associated NCV of 10 CFR Part 50, Appendix B, Criterion III, Design Control, was identified by the NRC inspectors for the failure to ensure the adequacy of the steam dryer/steam separator lifting device design. Specifically, the inspectors identified four examples where the licensee failed to perform adequate evaluations of the structural elements and structural connections in accordance with ANSI N14.6 requirements as defined in Updated Final Safety Analysis Report section 9.1.4.4. These issues were entered into the licensees corrective action program.
The finding was determined to be more than minor because the finding was associated with the Initiating Events Cornerstone objective to limit the likelihood of events that upset plant stability and challenge critical safety functions during shutdown. Specifically, the purpose of the lifting device design requirements was to limit the likelihood of a structural component failure, and hence, to ensure safe load handling of heavy loads over the reactor core or over safety-related systems. The inspectors determined the finding was of very low safety significance following a qualitative significance determination process review performed by the Region III Senior Risk Analyst. The inspector did not identify a cross-cutting aspect associated with this finding because the concern was related to a calculation from the 1980s, and thus was not necessarily indicative of current licensee performance. (Section 1R20)
Cornerstone: Mitigating Systems
- Green.
A finding of very low safety significance and an associated NCV of 10 CFR 50.55a(f), Inservice testing requirements, and 10 CFR Part 50, Appendix B,
Criteria V, Instructions, Procedures, and Drawings, was identified by the NRC inspectors. Specifically, the licensee failed to perform a required comprehensive pump test for division 1 and 2 emergency equipment cooling water makeup pumps within years of the start of the third inservice testing interval. The third inservice testing interval commenced on February 17, 2010, and included a requirement to perform a comprehensive pump test for the division 1 and 2 emergency equipment cooling water makeup pumps within two years and every two years thereafter. The required comprehensive pump tests were not performed prior to February 17, 2012.
The finding was determined to be more than minor because the finding was associated with the configuration control attribute of the Mitigating Systems Cornerstone and impacted the cornerstone objective of ensuring the capability of systems to prevent undesirable consequences (i.e., core damage). This finding was determined to be of very low safety significance because, following IMC 0609, Appendix E, Table 4a,
Characterization Worksheet for Initiating Events, Mitigating Systems, and Barrier Integrity Cornerstones, all questions were answered no. This finding has a cross-cutting aspect in the area of Human Performance, Decision Making, supervisory and management oversight aspect because the licensee failed to appropriately oversee the development and implementation of the comprehensive pump testing (H.4 (c)).
(Section 4OA2)
- Green.
A self-revealed finding of very low safety significance and an associated NCV of 10 CFR 50 Appendix B, Section V, Instructions, Procedures, and Drawings, was identified for the failure to adequately prevent foreign material from entering the hydraulic control unit for control rod 10-35, which caused control rod 10-35 to fail to fully insert on October 24, 2010. Subsequently, on November 18, 2011, control rod 10-35 again failed to fully insert during scram time testing. The root cause team identified the presence of foreign organic material and concluded it had been present for a long time,
i.e., at least since or prior to 2006, and this material was the cause of the deficient operation of control rod 10-35 in October 2010 and November 2011.
The inspectors determined this finding was more than minor because it was associated with the configuration control attribute of the Mitigating Systems Cornerstone and impacted the cornerstone objective of ensuring the capability of systems to prevent undesirable consequences (i.e., core damage). This finding was determined to be of very low safety significance because, following IMC 0609, Appendix E, Table 4a,
Characterization Worksheet for Initiating Events, Mitigating Systems, and Barrier Integrity Cornerstones, all questions were answered no. There was no cross-cutting aspect for this finding and NCV because the foreign material entered hydraulic control unit 10-35 sometime prior to 2006; and, therefore, the foreign material exclusion program inadequacies do not represent current performance. (Section 4AO2)
Licensee-Identified Violations
One violation of very low safety significance that was identified by the licensee has been reviewed by inspectors. Corrective actions planned or taken by the licensee have been entered into the licensees corrective action program. This violation and corrective action tracking numbers are listed in Section 4OA7 of this report.
REPORT DETAILS
Summary of Plant Status
Fermi Unit 2 started this inspection period shutdown, continuing forced outage 12-02 which commenced with the catastrophic failure of the south reactor feed pump turbine on June 25, 2012. The Unit remained shut down until July 22, 2012. The Unit increased power to 2 percent and returned to a shutdown condition to repair a valve motor. The Unit restarted on July 27, 2012, and achieved 68 percent power on July 30, 2012, using one main feedwater pump. The Unit maintained 68 percent power until September 14, 2012, when the Unit scrammed due to a fault in the 120 kV switchyard. The Unit commenced startup on September 19, 2012, achieved 68 percent power on September 20, 2012, and remained there for the remainder of the inspection period.
REACTOR SAFETY
Cornerstones: Initiating Events, Mitigating Systems, and Barrier Integrity
1R01 Adverse Weather Protection
.1 External Flooding
a. Inspection Scope
The inspectors evaluated the design, material condition, and procedures for coping with the design basis probable maximum flood. The evaluation included a review to check for deviations from the descriptions provided in the Updated Final Safety Analysis Report (UFSAR) for features intended to mitigate the potential for flooding from external factors.
As part of this evaluation, the inspectors checked for obstructions that could prevent draining, checked that the roofs did not contain obvious loose items that could clog drains in the event of heavy precipitation, and determined that barriers required to mitigate the flood were in place and operable. Additionally, the inspectors performed a walkdown of the protected area to identify any modification to the site which would inhibit site drainage during a probable maximum precipitation event or allow water ingress past a barrier. The inspectors also walked down underground bunkers/manholes subject to flooding that contained multiple train or multiple function risk-significant cables. The inspectors also reviewed the abnormal operating procedure for mitigating the design basis flood to ensure it could be implemented as written.

1R04 Equipment Alignment
.1 Quarterly Partial System Walkdowns
a. Inspection Scope
The inspectors performed partial system walkdowns of the following risk-significant systems:
- Mechanical isolation of main steam to the south reactor feed pump/turbine (RFPT) for Engineering Design Package (EDP) -36982;
- residual heal removal (RHR) system shutdown cooling during the forced outage; and
The inspectors selected these systems based on their risk significance relative to the Reactor Safety Cornerstones at the time they were inspected. The inspectors attempted to identify any discrepancies that could impact the function of the system and, therefore, potentially increase risk. The inspectors reviewed applicable operating procedures, system diagrams, UFSAR, Technical Specification (TS) requirements, outstanding work orders (WOs), condition reports, and the impact of ongoing work activities on redundant trains of equipment in order to identify conditions that could have rendered the systems incapable of performing their intended functions. The inspectors also walked down accessible portions of the systems to verify system components and support equipment were aligned correctly and operable. The inspectors examined the material condition of the components and observed operating parameters of equipment to verify there were no obvious deficiencies. The inspectors also verified the licensee had properly identified and resolved equipment alignment problems that could cause initiating events or impact the capability of mitigating systems or barriers and entered them into the corrective action program with the appropriate significance characterization. Documents reviewed are listed in the Attachment to this report.
These activities constituted three partial system walkdown samples as defined in IP 71111.04-05.
b. Findings
No findings were identified.

- auxiliary building, first floor mezzanine, cable run area;
- auxiliary building, second floor, division 2 switchgear room;
- auxiliary building, third floor control room, including computer room; and
- turbine building, first floor, north/center/south heater drain pump rooms.
The inspectors reviewed areas to assess if the licensee had implemented a fire protection program that adequately controlled combustibles and ignition sources within the plant, effectively maintained fire detection and suppression capability, maintained passive fire protection features in good material condition, and implemented adequate compensatory measures for out-of-service, degraded or inoperable fire protection equipment, systems, or features in accordance with the licensees fire plan. The inspectors selected fire areas based on their overall contribution to internal fire risk as documented in the plants Individual Plant Examination of External Events with later additional insights, their potential to impact equipment which could initiate or mitigate a plant transient, or their impact on the plants ability to respond to a security event.
Using the documents listed in the Attachment to this report, the inspectors verified fire hoses and extinguishers were in their designated locations and available for immediate use; fire detectors and sprinklers were unobstructed; transient material loading was within the analyzed limits; and fire doors, dampers, and penetration seals appeared to be in satisfactory condition.

- risk during emergency equipment cooling water (EECW) piping replacement with combustion turbine generator 11-1 maintenance and a reactor scram.
These activities were selected based on their potential risk significance relative to the Reactor Safety Cornerstones. As applicable for each activity, the inspectors verified risk assessments were performed as required by 10 CFR 50.65(a)(4) and were accurate and complete. When emergent work was performed, the inspectors verified the plant risk was promptly reassessed and managed. The inspectors reviewed the scope of maintenance work, discussed the results of the assessment with the licensee's probabilistic risk analyst or shift technical advisor, and verified plant conditions were consistent with the risk assessment. The inspectors also reviewed TS requirements and walked down portions of redundant safety systems, when applicable, to verify risk analysis assumptions were valid and applicable requirements were met.
Specific documents reviewed during this inspection are listed in the Attachment to this report.
These maintenance risk assessments and emergent work control activities constituted five samples as defined in IP 71111.13-05.
b. Findings

- CARD 12-26429, In-Service Testing Program Comprehensive Pump Test for EECW Makeup Pump; and
- CARD 12-27126, Further Reduction in North RFP Moisture Level.
The inspectors selected these potential operability issues based on the risk significance of the associated components and systems. The inspectors evaluated the technical adequacy of the evaluations to ensure TS operability was properly justified and the subject component or system remained available such that no unrecognized increase in risk occurred. The inspectors compared the operability and design criteria in the appropriate sections of the TSs and UFSAR to the licensees evaluations to determine whether the components or systems were operable. Where compensatory measures were required to maintain operability, the inspectors determined whether the measures in place would function as intended and were properly controlled. The inspectors determined, where appropriate, compliance with bounding limitations associated with the evaluations. Additionally, the inspectors reviewed a sampling of corrective action documents to verify the licensee was identifying and correcting any deficiencies associated with operability evaluations. Documents reviewed are listed in the to this report.
This operability inspection constituted four samples as defined in IP 71111.15-05.

b. Findings
1) Inspection Procedure for Reactor Pressure Vessel Head Strongback and Steam Dryer/Steam Separator Lifting Device Omitted Dimensional Testing and Nondestructive Testing Requirements
Introduction:
The inspectors identified a finding of very low safety significance (Green) and an associated NCV of 10 CFR Part 50, Appendix B, Criterion V, Instructions, Procedures, and Drawings, in that, the procedure used to demonstrate compliance with ANSI N14.6-1978, Standard for Special Lifting Devices for Shipping Containers Weighing 10,000 pounds (4500 kg) or More for Nuclear Materials, Section 5.3.1, provisions did not include dimensional testing of reactor pressure vessel (RPV) head strongback and steam dryer/steam separator lifting device. In addition, several major load carrying welds and critical areas of steam dryer/steam separator lifting device were not being nondestructively tested in accordance with the provisions specified in ANSI N14.6-1978. As a result, the licensee used the RPV head strongback and steam dryer/steam separator lifting device during each refueling outage without performing dimensional testing of RPV head strongback and steam dryer/steam separator lifting device and without performing nondestructive testing of major load carrying welds and critical areas of the steam dryer/steam separator lifting device.
Description:
Section 3.2-1 of the UFSAR, classified both the RPV head strongback and steam dryer/steam separator lifting device as having quality assurance requirements in accordance with 10 CFR Part 50 Appendix B. Section 9.1.4.4 of the UFSAR states in part, "The special lifting devices at Fermi 2 are the reactor pressure vessel head strongback and the dryer/steam separator lifting device. Periodic testing of these special lifting devices meets the guidelines of NUREG-0612, Control of Heavy Loads at Nuclear Power Plants, by following ANSI N14.6-1978. Section 5.3.1 of ANSI N14.6-1978 requires each special lifting device be subjected to either a load test or dimensional testing, visual inspection, and nondestructive testing of major load carrying welds and critical areas. The licensee implemented the second option and hence did not perform a load test of the RPV head strongback and steam dryer/steam separator lifting device.
Preventative Maintenance Activity No. F130, Perform NDE on Special Lifting Device identified the only major load carrying welds for the steam dryer/separator lifting device as part of detail A of Fermi Drawing 6C721-2201, Design and Details of Dryer/Separator Lifting Device, Revision B. The inspectors noted that Calculation DC-3266, Design Check for Rigging Apparatus, Revision A, evaluated the design adequacy of the major load carrying welds on the steam dryer/steam separator lifting device. In addition to detail A, Calculation DC-3266 identified the major load carrying welds were also part of Section 1 and socket box detail of Drawing 6C721-2201. The licensee agreed Section 1 and socket box detail of Drawing 6C721-2201 were major load carrying welds as well. The inspectors also determined that Procedure 32.RIG.018, Guidelines and Practices for the Use of Hoisting and Rigging Equipment, Revision 8, did not include the ANSI N14.6-1978 requirement to perform dimensional testing of the RPV head strongback and steam dryer/steam separator lifting device. The licensee could not produce documentation to verify nondestructive testing of load carrying welds associated with Section 1 and socket box detail of Drawing 6C721-2201 welds were performed as well as dimensional testing of both the strongback and the lifting device. In response to these concerns, the licensee initiated CARD 12-27537, NRC Identified NDE Inspections, dated September 12, 2012, to address these concerns.
Analysis:
The inspectors determined the failure to perform dimensional testing of RPV head strongback and steam dryer/steam separator lifting device and nondestructive testing of several of the steam dryer/steam separator lifting device major load carrying welds and critical areas was contrary to the ANSI N14.6-1978 provisions and was a performance deficiency. The finding was determined to be more than minor in accordance with IMC 0612, Appendix B, Issue and Screening, Minor Question 4, because the finding was associated with the Initiating Events Cornerstone attribute of equipment performance and affected the cornerstone objective to limit the likelihood of those events that upset plant stability and challenge critical safety functions during shutdown. Specifically, the purpose of the dimensional testing and nondestructive testing of RPV head strongback and steam dryer/steam separator lifting device is to limit the likelihood of a structural component failure, hence, ensuring safe load handling of heavy loads over the reactor core or over safety-related systems.
The inspectors determined the finding could be evaluated using IMC 0609, Appendix A, The Significance Determination Process (SDP) for Findings At-Power, Exhibit 1, for the Initiating Events Cornerstone. The inspectors determined the finding would be related to a transient initiator, which could cause a reactor trip and loss of mitigation equipment.
Therefore, the Region III senior reactor analyst (SRA) performed a more detailed risk evaluation. Since the plant would be shutdown when the RPV head strongback or steam dryer/steam separator lifting device was used, the RIII SRA conducted the assessment of the risk significance using IMC 0609, Appendix G, Shutdown Operations SDP. Table 1 of Appendix G, Losses of Control, does not apply since no event occurred. The SRA reviewed Appendix G, Attachment 1, Shutdown Operations SDP, Phase I Operational Checklists for Both Pressurized Water Reactors (PWRs) and Boiling Water Reactors (BWRs). The applicable checklist was Checklist 6, BWR Cold Shutdown or Refueling Operation - Time to Boil < 2 hour2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br />s: Reactor Coolant System level < 23' Above Top of Flange. The applicable safety functions impacted were decay heat removal and inventory control. The SRA continued the risk-evaluation with a Phase II SDP assessment.
The SRA reviewed Appendix G, Attachment 3, Phase II Significance Determination Process Template for BWR during Shutdown. In Phase II, the most limiting plant operating state was POS-1 with an early time window. The SRA evaluated the impact of the performance deficiency on the loss of decay heat (i.e., loss of residual heat removal (LORHR)) and loss of inventory initiators in Appendix G. Both initiators were representative of condition findings as defined in Appendix G, Attachment 3.
For each initiator, the estimated initiating event likelihood (IEL) was 3E-4/yr. The licensee provided data from Fermi's past two refueling outages that showed the RPV head strongback and steam dryer/steam separator lifting device are used to move a very heavy load a combined eight times per refuel outage (for approximately 10 hours1.157407e-4 days <br />0.00278 hours <br />1.653439e-5 weeks <br />3.805e-6 months <br /> per outage). At Fermi refuel outages are held every 18 months. Based on this, the number of lifts over a 12-month period was computed to be 5.3 lifts. The SRA also used information in NUREG 1774, A Survey of Crane Operating Experience at U.S. Nuclear Power Plants from 1968 through 2002, to obtain an estimate of failure probability of the RPV head strongback and steam dryer/steam separator lifting device. Based on actual crane operating experience data from Commercial U.S. Nuclear Power Plants, this NUREG estimated the probability of load drops per demand for very heavy loads to be 5.6E-05. Thus the IEL of 3E-4/yr was estimated based on 5.3 lifts per year with a failure probability of 5.6E-5 per lift. The SRA noted the licensee visually inspected the strongback and lifting device prior to each use and performed limited nondestructive examination every five years with no deficiencies identified, so this IEL may be conservative for Fermi.
Regarding loss of inventory, the mitigating functions for this initiator were evaluated using Worksheet 1, SDP for a BWR Plant - Loss of Inventory in POS 1. The result of the loss of inventory initiator was 9E-9. In Worksheet 1, the dominant sequences involved failure of manual low and high pressure injection, and failure to isolate the loss of inventory or failure of reactor coolant system (RCS) pressure control.
Regarding loss of operating train of RHR, the mitigating functions for this initiator were evaluated using Worksheet 4, SDP for a BWR Plant - Loss of Operating Train of RHR in POS 1. The result of the LORHR initiator was 6E-10. In Worksheet 4, the dominant accident sequences involved failure of manual low and high pressure injection and failure of RHR recovery or failure of containment venting.
The total risk result of the internal event analysis is the sum of the individual results from the initiators above adjusted by the counting rule (i.e., multiply by 3.3) that is described in IMC 0609, Appendix A. The total internal event delta core damage frequency is on the order of 3.2E-8/yr. The SRA reviewed the licensee's risk evaluation. The licensee calculated a cumulative frequency of 8.4E-7/yr based on the load drop event tree in Figure 21 from NUREG 1774. This frequency was only the frequency that safe shutdown equipment is damaged from a load drop, not necessarily a core damage frequency.
Based on these results, the SRA determined the risk of this performance deficiency to be of very low safety significance (Green). The inspector did not identify a cross-cutting aspect associated with this finding because the concern was related to licensing requirements established from the 1980s, and thus was not necessarily indicative of current licensee performance.
Enforcement:
Title 10 CFR Part 50, Appendix B, Criterion V, Instructions, Procedures, and Drawings, requires, in part, that activities affecting quality be prescribed by documented instructions, procedures, or drawings, of a type appropriate to the circumstances and be accomplished in accordance with these instructions, procedures, or drawings. Section 5.3.1 of ANSI N14.6-1978 requires, In cases where surface cleanliness and conditions permit, the load testing may be omitted and dimensional testing, visual inspection, and nondestructive testing of major load-carrying welds and critical areas in accordance with Section 5.5 of this standard shall suffice.
Contrary to the above, the licensee failed to have activities prescribed in documented instructions or procedures to ensure the ANSI N14.6-1978 provisions to perform dimensional testing of the RPV head strongback and steam dryer/steam separator lifting device was performed. Also, the licensee failed to have activities prescribed in documented instructions or procedures to ensure the ANSI N14.6-1978 provisions to perform nondestructive testing of several specific load carrying welds of steam dryer/steam separator lifting device was performed. Specifically, these provisions were not included in Procedure 32.RIG.018 and Preventative Maintenance Activity F130.
Because this violation was of very low safety significance and it was entered into the licensees corrective action program as CARD 12-27537, this violation is being treated as an NCV, consistent with Section 2.3.2 of the NRC Enforcement Policy. Inspection Procedure for Reactor Pressure Vessel Head Strongback and Steam Dryer/Separator Lifting Device Omitted Testing Requirement (NCV 05000341/2012004-01).
2) Inadequate Evaluation of Steam Dryer/Steam Separator Lifting Device
Introduction:
The inspectors identified a finding of very low safety significance (Green)and an associated NCV of 10 CFR Part 50, Appendix B, Criterion III, Design Control, for failure to provide adequate design control measures for the steam dryer/steam separator lifting device. Specifically, the inspectors identified four examples where the licensee failed to perform adequate evaluations of the lifting device in accordance with ANSI N14.6 provisions as defined in UFSAR Section 9.1.4.4. As a result, the design basis calculation was not sufficient to ensure conformance with UFSAR requirements for safe load handling of heavy loads over the reactor core or over safety-related systems.
Description:
Section 3.2 of the UFSAR classified the steam dryer/steam separator lifting device as having quality assurance requirements in accordance with 10 CFR Appendix B. Section 9.1.4.4 of the UFSAR required the steam dryer/steam separator lifting device design to meet the provisions of ANSI N14.6-1978. Calculation DC-3266, Design Check for Rigging Apparatus, Revision A, was used to demonstrate compliance with ANSI N14.6.
During a review of the aforementioned calculation the inspectors identified the following four representative examples in which the licensee failed to meet the ANSI N14.6 provisions:
1. ANSI N14.6-1978, Section 3.2.1.1, states in part, "The load-bearing members of a special lifting device shall be capable of lifting three times the combined weight of the shipping container with which it will be used, plus the weight of intervening components of the special lifting device. Calculation DC-3266 did not meet this provision in that the weight of the lifting device and its intervening components were not included in the design.
2. ANSI N14.6-1978, Section 3.2.1.1, states in part, "When materials that have yield strengths above 80 percent of their ultimate strength are used, each case requires special consideration, and the foregoing stress design factors do not apply. Design shall be on the basis of the materials fracture toughness, and the designer shall establish the criteria." The socket lifting pin and adapter lifting pin of the lifting device had yield strengths greater than 80 percent of their ultimate strengths. Calculation DC-3266 did not design these structural elements based on their fracture toughness properties.
3. ANSI N14.6-1978, Section 3.2.1.1, states in part, "The load-bearing members of a
special lifting device shall be capable of lifting three times the combined weight of the shipping container with which it will be used, plus the weight of intervening components of the special lifting device, without generating a combined shear stress or maximum tensile stress at any point in the device in excess of the corresponding minimum yield strength of their materials of construction. Calculation DC-3266 performed an analysis of the vertical stiffeners for the lifting device. The analysis showed the stiffeners have an applied stress greater than the allowable stress which would exceed the minimum yield strength of the stiffener material.
4. ANSI N14.6-1978, Section 3.2.1.1, states in part, "The load-bearing members of a
special lifting device shall be capable of lifting three times the combined weight of the shipping container with which it will be used, plus the weight of intervening components of the special lifting device, without generating a combined shear stress or maximum tensile stress at any point in the device in excess of the corresponding minimum yield strength of their materials of construction. They shall also be capable of lifting five times that weight without exceeding the ultimate strength of the materials. Calculation DC-3266 did not analyze each and every structural element and connection for the stress design factors based on the yield and the ultimate strength of the material.
In response to this concern, the licensee initiated CARD 12-27276, NRC Identified-Revise Calculation DC-3266, Volume I, dated August 31, 2012, to address these concerns.
Analysis:
The inspectors determined the failure to meet the Section 3.2.1 design provisions of ANSI N14.6 for the steam dryer/steam separator lifting device was a performance deficiency.
The finding was determined to be more than minor in accordance with IMC 0612, Appendix B, Issue and Screening, Minor Question 4, because the finding was associated with the Initiating Events Cornerstone attribute of design control and affected the cornerstone objective to limit the likelihood of those events that upset plant stability and challenge critical safety functions during shutdown. Specifically, the purpose of the lifting device design requirements was to limit the likelihood of a structural component failure, and hence, to ensure safe load handling of heavy loads over the reactor core or over safety-related systems.
The inspectors determined the finding could be evaluated using IMC 0609, Appendix A, The SDP for Findings At-Power, Exhibit 1, for the Initiating Events Cornerstone. The inspectors determined the finding would be related to a transient initiator which could cause a reactor trip and loss of mitigation equipment. Therefore, the Region III SRA performed a more detailed risk evaluation. The Region III SRA determined the risk significance documented in Section 1R20.2.b.1) of this report applies to this finding as well. As stated in Section 1R20.2.b.1), the SRA determined the risk of the finding to be of very low safety significance (Green). The inspector did not identify a cross-cutting aspect associated with this finding because the concern was related to a calculation from the 1980s, and thus was not necessarily indicative of current licensee performance.
Enforcement:
Title 10 CFR Part 50, Appendix B, Criterion III, Design Control, states, in part, that the design control measures shall provide for verifying or checking the adequacy of design, such as by the performance of design reviews, by the use of alternate or simplified calculation methods, or by the performance of a suitable testing program.
Contrary to the above, on August 31, 2012, the inspectors determined that for Calculation DC-3266 the licensees design control measures failed to ensure adequacy of the design. Specifically, this calculation did not conform to and was nonconservative with respect to ANSI N14.6 provisions.
Because this violation was of very low safety significance (Green) and it was entered into the licensees corrective action program as CARD 12-27276, this violation is being treated as an NCV, consistent with Section 2.3.2 of the NRC Enforcement Policy.

- refuel floor activities including vessel assembly and disassembly;
- refuel floor activities including in-vessel inspections; and
- drywell access above 627 for the E2100F006A valve.
The inspectors reviewed the ALARA work activity evaluations, exposure estimates, and exposure mitigation requirements. The inspectors determined whether the licensee reasonably grouped the radiological work into work activities based on historical precedence, industry norms, and/or special circumstances.
The inspectors assessed whether the licensees planning identified appropriate dose mitigation features; considered alternate mitigation features; and defined reasonable dose goals. The inspectors evaluated whether the licensees ALARA assessment had taken into account decreased worker efficiency from use of respiratory protective devices and/or heat stress mitigation equipment (e.g., ice vests). The inspectors determined whether the licensees work planning considered the use of remote technologies (e.g., teledosimetry, remote visual monitoring, and robotics) as a means to reduce dose and the use of dose reduction insights from industry operating experience and plant-specific lessons learned. The inspectors assessed the integration of ALARA requirements into work procedure and radiation work permit documents.
The inspectors compared the results achieved (dose rate reductions, person-rem used)with the intended dose established in the licensees ALARA planning for these work activities. The inspectors compared the person-hour estimates provided by maintenance planning and other groups to the radiation protection group with the actual work activity time requirements, and evaluated the accuracy of these time estimates.
The inspectors assessed the reasons (e.g., failure to adequately plan the activity, failure to provide sufficient work controls) for any inconsistencies between intended and actual work activity doses.
The inspectors determined whether post-job reviews were conducted and if identified problems were entered into the licensees corrective action program.
b. Findings
No findings were identified.

- CARD 12-24565, MG Set Stops Incorrectly Set During Performance of 54.000.20.
The inspectors reviewed the CARD 12-24565 investigation, cause determination, corrective actions, the reactivity event classification for this event, and conducted interviews. Documents reviewed in this inspection are listed in the Attachment to this report.
This review constituted one in-depth problem identification and resolution sample as defined in IP 71152-05.
b. Observations
Introduction:
On May 16, 2012, procedure 54.000.20, Reactor recirculation system MG (RRMG) set scoop tube positioner operability test, was performed to set mechanical, electrical, and distributed control system (DCS) stops for both the A and the B RRMG sets. Both RRMG set speeds and core flow were varied to collect data, establish a least squares fit of the data, and then extrapolate the data to establish the mechanical, electrical and DCS set points. On May 17, 2012, the residents reviewed a copy of the completed procedure and noted the extrapolated data points did not fall upon the least squares fit regression line. The resident identified this discrepancy to the reactor engineering supervisor.
Discussion: On May 16, 2012, procedure 54.000.20, Reactor recirculation system MG set scoop tube positioner operability test, was performed to set mechanical, electrical, and DCS stops for both the A and the B RRMG sets. Both RRMG set speeds and core flow were varied to collect data. Procedure 54.000.20 requires the data collected in attachment 1 (i.e., by varying core flow and RRMG set speeds) to be plotted on a graph and extrapolated to determine the mechanical, electrical and DCS setpoints.
Functionally equivalent computer-generated plots can be used and annotated. In this case, an Excel spreadsheet was used to input the data and establish the regression line.
The Excel spreadsheet settings were such that the spreadsheet calculations for the extrapolated points were not updated in real-time. This resulted in printouts that were used to complete procedure 54.000.20 not having correctly propagated results, and therefore, the mechanical high speed stops, electrical stops, and DSC high speed limits were incorrectly set.
The engineers had never reviewed the overall plot of the data in completing procedure 54.000.20, but relied upon their use of an Excel spreadsheet. Consequently, the licensee identified this issue as a procedural violation.
This resulted in the A RRMG set stops to have been set incorrectly and conservatively, while the B RRMG set stops were set incorrectly and non-conservatively. The B RRMG set stops was a near miss to Technical Requirements Manual specification 3.4.7.1 violation because the incorrect settings were below the value specified in Cycle 16, Core Operating Limits Report, Revision 0, Table 2.
Further, the residents reviewed the completed procedure 54.000.20 archived in the licensees document management system. This procedure and work order had a designated review by reactor engineering required following the performance of the procedure. The residents were advised that the reactor engineering reviewer was knowledgeable of the issues raised in CARD 12-24565; however, there was no documentation provided of the deficiencies in setting the mechanical high speed stops, electrical stops, or DCS high speed limits, and no listing of CARD 12-24565 provided by the reviewer.
Conclusions: Incorrectly setting the RRMG set mechanical stops was a near miss to a Technical Requirements Manual violation. Additionally, failing to validate the data collected and extrapolated to establish the mechanical, electrical, and DCS stops was a fundamental engineering process weakness, which resulted in a human performance departmental reset. Finally, designated reviewers should critically identify deficiencies identified during the review process. This provides more complete documentation of issues and concerns, (i.e., including known deficiencies for archival purposes).
c. Findings
No findings were identified.
.4 Selected Issue Follow-Up Inspection: Failure to Perform American Society of
Mechanical Engineers Inservice Testing Comprehensive Pump Tests Requirement for Emergency Equipment Cooling Water Make-up Pumps
a. Inspection Scope
The inspectors selected the investigation of the failure to perform the ASME IST required comprehensive pump tests (CPTs) for the division 1 and 2 EECW makeup pumps. The third IST interval commenced on February 17, 2010, and included a requirement to perform a CPT for the division 1 and 2 EECW makeup pumps within two years and every two years thereafter. The required CPT tests were not performed prior to February 17, 2012. The inspectors reviewed CARD 11-20585, which identified the CPT requirement; CARD 12-26429, which identified the difficulties in performance of the CPT and established a team to investigate the feasibility of performing the CPT for the EECW makeup pumps; CARD 12-26834, which documented the inability to perform the CPT for division 1 prior to August 15, 2012; and CARD 12-26860, which identified the NRC inspectors concern with failure to perform the CPT in February.
This review constituted one in-depth problem identification and resolution sample as defined in IP 71152-05.
b. Findings
Introduction:
The inspectors identified a finding of very low safety significance (Green) and an associated NCV of 10 CFR 50.55a(f), Inservice Testing Requirements, and 10 CFR 50, Appendix B, Criteria V, Instructions, Procedures, and Drawings, for failure to perform a required CPT for division 1 and 2 EECW makeup pumps within two years of the start of the third IST interval. The third IST interval commenced on February 17, 2010, and included a requirement to perform a CPT for the division 1 and 2 EECW makeup pumps within two years and every two years thereafter. The required CPT tests were not performed prior to February 17, 2012.
Description:
On February 17, 2010, Fermi 2 commenced their third IST interval. The IST program owner identified a requirement to perform a CPT for the division 1 and 2 EECW makeup pumps. The IST program owner reviewed the Operations and Maintenance (OM) Code and determined the CPT required testing the EECW makeup pumps at or near their best efficiency point. This required a significant operation or evolution (SOE) to perform the initial CPT to utilize as the baseline data, and the CPT would then be performed every two years thereafter. CARD 11-20585 was initiated to develop the testing plan and the procedure, identify and assemble the required test equipment, and conduct the SOE prior to February 17, 2012. During the timeframe CARD 11-20585 was initiated and approximately mid-February 2012 several meetings were conducted with the IST program owner, system engineering, plant support engineering, and operations with no conclusive actions agreed upon. In addition, neither of the two work orders for the performance of the CPT SOEs for the EECW makeup pumps were ever entered into the work control system with a schedule for the required date of February 17, 2012.
There is no evidence of the IST program owner evaluating TS 5.5.6, IST and inspection program, and surveillance requirement 3.0.2 and applying the specific provisions and limitations of surveillance requirement 3.0.2 to the required EECW makeup pump CPT SOEs. Likewise, there is no evidence of any documented evaluations of any IST program deficiencies or nonconformances regarding failure to perform the CPT SOEs on or prior to the due date.
Title 10 CFR 50.55a(f), Inservice Testing Requirements, provides requirements for IST.
The licensee is currently in their third 120-month interval of their IST program, which commenced February 17, 2010. The code of record for the licensee is the ASME Operations and Maintenance of Nuclear Power Plants Code 2004 Edition with no addenda. The IST requirement for performance of a CPT for the division 1 and 2 EECW makeup pumps was not performed as required. No relief had been requested by the licensee. Technical Specification 5.5.6, Inservice Testing and Inspection Program, applied the provisions of surveillance requirement 3.0.2 to the testing frequencies listed.
Again, however, there is no evidence that the IST program owner evaluated the specific provisions and limitations of surveillance requirement 3.0.2 and applied them to the required EECW makeup pump CPT SOEs.
In addition, 10 CFR 50 Appendix B, Section V, Instructions, Procedures, and Drawings, 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, the Engineering Support Conduct Manual, Chapter 23 (MES23),
Section 3.8, Inservice Inspection and Inservice Testing, provides that, inservice testing shall be scheduled, conducted, and documented in accordance with the approvedIST plan. Contrary to the above, the required EECW makeup pump CPT SOEs were not scheduled or performed prior to February 17, 2012, and there was no documentation of this nonconformance.
Although not issued until after the February 16, 2012, due date of this surveillance, Enforcement Guidance Memorandum (EGM) 12-001, issued February 24, 2012, provides enforcement discretion to TS Section 5.0, since the revision to the standard TSs to make the provisions of SR 3.0.2 (and SR 3.0.3) applicable also made the Section 3.0, Surveillance requirement applicability, applicable to the TS Section 5.0. The result was that applying the standard TS rules of usage would prohibit licensees from using the SR 3.0.2 (and 3.0.3) allowances for TS Section 5.0. The EGM further points out the OM Code does not make available test allowances similar to either SR 3.0.2 (or SR 3.0.3)under 10 CFR 50.55a(f). Note, the OM Code committee has recently developed a code case which models SR 3.0.2 to make available up to an additional 25 percent of the test frequency. As yet, however, the code case has neither been approved and issued by the ASME nor endorsed by the NRC. In this situation there is no evidence the IST program owner evaluated the provisions and limitations of SR 3.0.2 and applied them to the required EECW makeup pump CPT SOEs. Therefore, the provisions of EGM 12-001 do not appear to apply.
Analysis:
The inspectors determined the failure to perform the ASME OM Code IST required CPT for the division 1 and 2 EECW makeup pumps was a performance deficiency that required evaluation using the SDP. The inspectors determined this finding was more than minor because it was associated with the configuration control attribute of the Mitigating Systems Cornerstone and impacted the cornerstone objective of ensuring the capability of systems to prevent undesirable consequences (i.e., core damage). This finding was determined to be of very low safety significance because, following IMC 0609, Appendix E, Table 4a, Characterization Worksheet for Initiating Events, Mitigating Systems, and Barrier Integrity Cornerstones, all questions were answered no. Therefore, the finding was determined to be of very low safety significance (Green).
This finding has a cross-cutting aspect in the area of Human Performance, Decision Making, supervisory and management oversight aspect because the licensee failed to appropriately oversee the development and implementation of the CPT (H.4 (c)).
Enforcement:
Title 10 CFR 50.55a(f), Inservice Testing Requirements, provides requirements for IST. The licensee is currently in their third 120-month interval of their IST program, which commenced February 17, 2010. The code of record for the licensee is the ASME OM Code 2004 Edition with no addenda. The IST requirement for performance of a CPT for the division 1 and 2 EECW makeup pumps was not performed as required.
Further, 10 CFR 50 Appendix B, Section V, Instructions, Procedures, and Drawings, requires, in part, that activities affecting quality shall be prescribed by documented instructions, procedures, or drawing of a type appropriate to the circumstances and shall be accomplished in accordance with these instructions, procedures, or drawings. The Engineering Support Conduct Manual, Chapter 23 (MES23), Section 3.8, Inservice Inspection and Inservice Testing, provides that, inservice testing shall be scheduled, conducted, and documented in accordance with the approvedIST Plan. Contrary to the above, required EECW makeup pump CPTs were not scheduled or performed prior to February 17, 2012, and there was no documentation of this nonconformance.
Because the violation was of very low safety significance and it was entered into your corrective action program (CARD 12-26429 and CARD 12-26860), this violation is being treated as an NCV, consistent with Section 2.3.2 of the NRC Enforcement Policy.

.5 Selected Issue Follow-up Inspection: Failure of Control Rod 10-35 to Fully Scram during
Scram Time Testing (Closed) URI 05000341/2012003-01; Control Rod 10-35 Failure to Scram
a. Inspection Scope
The inspectors selected the investigation of the failure of control rod 10-35 to fully scram during scram time testing conducted on November 18, 2011. CARD 11-30357 was issued and the investigation identified foreign organic material in the inlet of the scram outlet valve, C11-F127. Previously, control rod 10-35 had failed to fully insert following an automatic reactor scram on October 24, 2010 (CARD 10-29509). The apparent cause evaluation attributed this failure to a hydraulic lock caused by blockage in the flow path between the control rod drive mechanism and the scram discharge volume. The inspectors reviewed the CARD 11-30357 root cause evaluation, and the CARD 10-29509 apparent cause evaluation. They directly observed various portions of the investigation to identify the deficiencies in the performance of control rod 10-35.
Documents reviewed in this inspection are listed in the Attachment.
This inspection is a continuation of a selected issue followup inspection initiated and counted as a sample in the first quarter (Inspection Report 05000341/2012002).
b. Findings
.
Introduction:
A self-revealed finding of very low safety significance and an associated NCV of 10 CFR 50 Appendix B, Section V, Instructions, Procedures, and Drawings, was identified for the failure to adequately prevent foreign material from entering the hydraulic control unit for control rod 10-35, which caused control rod 10-35 to fail to fully insert on October 24, 2010. Subsequently, on November 18, 2011, control rod 10-35 again failed to fully insert during scram time testing. The root cause team identified the presence of foreign organic material and concluded it had been present for a long time (i.e., at least since or prior to 2006), and this material was the cause of the deficient operation of control rod 10-35 in October 2010 and November 2011.
Description:
On October 24, 2010, control rod 10-35 failed to insert upon actuation of an automatic reactor scram caused by loss of condenser vacuum (CARD 10-29509). An emergent issue team was formed to investigate this event. The apparent cause was determined to be a hydraulic lock caused by blockage in the flow path between the control rod drive mechanism and the scram discharge volume. The licensee never found any foreign material, but postulated that the likely foreign material was discharged into the scram discharge volume, ultimately ending up in the torus room sump. As a corrective action, for cycle 15 the licensee increased the frequency of performing TS surveillance 3.1.4.2 scram time testing to every 100 days, adjusted the representative sample size to assure all rods would be tested during cycle 15, and included control rod 10-35 in each quarterly scram time testing sample.
On November 18, 2011, during scram time testing, control rod 10-35 again failed to fully insert. CARD 11-30357 was issued and the root cause evaluation team identified the direct cause of the failure as foreign organic material found in the inlet of the scram outlet valve, C11-F127. The root cause was identified as less than adequate barriers for preventing the entry of foreign material into the control rod drive hydraulic system. The root cause evaluation team further determined there had been significant program changes to the foreign material exclusion program since 2006, which were sufficient to prevent foreign material from entering hydraulic control unit 10-35.
Further, the inspectors found that Quality Assurance Conduct Manual, Chapter 11 (MQA11), Enclosure B, Section 3.0, Significant Condition Adverse to Quality Determination Criteria, provides the specific criteria for significant condition adverse to quality determination. This determination for CARD 11-30357 had been made by the CARD review board prior to completion of the root cause evaluation. The inspectors observed two criteria from MQA11, Enclosure B, Section 3.0 which seemed to fit the findings regarding the investigation into the failure of control rod 10-35 to fully insert; MQA11, Enclosure B, Section 3.0, item 6., repetitive items, or MQA11, Enclosure B, Section 3.0, item 3, deviations that require extensive evaluation. The investigation details appeared to meet both of these criteria.
Analysis:
The inspectors determined that failure to prevent the entry of foreign material into the hydraulic control unit of control rod 10-35 was a performance deficiency that required evaluation using the SDP. The inspectors determined this finding was more than minor because it was associated with the configuration control attribute of the Mitigating Systems cornerstone and impacted the cornerstone objective of ensuring the capability of systems to prevent undesirable consequences (i.e., core damage). This finding was determined to be of very low safety significance because, following IMC 0609, Appendix E, Table 4a, Characterization Worksheet for Initiating Events, Mitigating Systems, and Barrier Integrity Cornerstones, all questions were answered no. Therefore, the finding was determined to be of very low safety significance (Green).
There is no cross-cutting aspect for this finding and NCV because the foreign material entered hydraulic control unit 10-35 sometime prior to 2006; and therefore, the foreign material exclusion program inadequacies do not represent current performance.
Enforcement:
Title 10 CFR 50 Appendix B, Section V, Instructions, Procedures, and Drawings, requires, in part, activities affecting quality shall be prescribed by documented instructions, procedures, or drawing of a type appropriate to the circumstances and shall be accomplished in accordance with these instructions, procedures, or drawings. Contrary to the above, the root cause evaluation identified less-than-adequate foreign material exclusion program requirements (that had been improved subsequent to 2006) and failed to prevent the entry of foreign material into the hydraulic control unit for control rod 10-35.
Because the violation was of very low safety significance and it was entered into your corrective action program as CARD 11-30357, this violation is being treated as an NCV, consistent with Section 2.3.2 of the NRC Enforcement Policy. Failure of Control Rod 10-35 to Fully Scram during Scram Time Testing (NCV 05000341/2012004-04).
This finding and NCV closes unresolved item (URI)05000341/2012003-01, Control Rod 10-35 Failure to Scram.
4OA3 Follow-Up of Events and Notices of Enforcement Discretion
.1 (Closed) Licensee Event Report 05000341/2012-001; Loss of Shutdown Cooling Due to
a Voltage Transient On April 11, 2012, Operations was clearing tags in preparation for bus 65E restoration.
Step 61 of STR 2012-001122 had connected a ground truck in bus 65E position E4 and installed a red danger tag. The ground truck was installed to perform work on bus 65E and load shedding string. The ground truck was not removed prior to energizing the bus. The breaker installed in bus 65E position E9 immediately tripped due to a fault and as a result of the electrical transient, the A RHR pump tripped while operating in shutdown cooling mode with the plant in Mode 5 for RFO-15. The pump trip was caused by an isolation of the division 1 RHR shutdown cooling inboard isolation valve E1150F009. A self-revealed Green finding and associated NCV of 10 CFR 50 Appendix B, Section V, Instructions, Procedures, and Drawings, was identified for this event and included in Inspection Report 05000341/2012003, section 4OA3. No additional findings were identified following review of this licensee event report (LER).
Documents reviewed as part of this inspection are listed in the Attachment to this report.
This LER is closed.
This event follow-up review constituted one sample as defined in IP 71153-05.
.2 (Closed) Licensee Event Report 05000341/2012-002; Reactor Scram during Reactor
Pressure Vessel Hydrostatic Test On April 26, 2012, surveillance procedure 24.137.21, Reactor Pressure Vessel System Leakage Test was in progress with the plant operating in Mode 4 (Cold Shutdown). All control rods were inserted. The surveillance was classified as an infrequently performed test or evolution, because of the safety significance of the testing and since the test is performed only once per cycle. Control rod scram time testing and excess flow check valve testing were also in progress, as allowed by the precautions and limitations of the RPV system leakage test procedure.
A dedicated pressure control operator was assigned to maintain RPV pressure in the band of 1030 to 1055 psig as specified by the RPV system leakage test procedure.
Pressure was controlled by using a combination of reactor water cleanup blowdown and control rod drive system flow adjustments. The dedicated pressure control operator selected a process computer point to display on a highly visible screen near the pressure control station. The selected point, B21CP6601, was displaying a reactor pressure average using two inputs. Due to ongoing excess flow check valve testing, one input to the average reactor pressure computer point became invalid as its instruments were removed from service prescribed by the excess flow check valve test. As a result, RPV pressure as seen by the process computer point, B21CP6601, lowered as isolated instruments slowly bled down (i.e., relieved pressure). Based on this false indication, the dedicated pressure control operator informed the control room supervisor that RPV pressure was lowering. At this time, actual reactor pressure was slowly rising. No adjustments were made based on these indications; and after approximately three minutes, RPV pressure reached the high pressure scram setpoint (1093 psig) causing a reactor scram. A self-revealed Green finding and associated NCV of TS 5.4.1.a for the licensees failure to establish and implement procedures recommended by Regulatory Guide 1.33, was identified for this event and included in Inspection Report 05000341/2012003, section 4OA3. No additional findings were identified following review of this LER. Documents reviewed as part of this inspection are listed in the to this report. This LER is closed.
This event follow-up review constituted one sample as defined in IP 71153-05.
.3 (Discussed) Licensee Event Report (LER) 05000341/2012-003; Reactor Scram Due to
Degrading Condenser Vacuum This event occurred on June 25, 2012. After completing repairs to main unit transformer 2B, reactor power was raised to approximately 22 percent and the unit was synchronized to the power grid. Shortly after operations began to increase power, multiple vibration-related alarms were received for the south reactor feed pump, and the pump tripped. The south reactor feed pump had catastrophically failed and as a result, condenser vacuum was decreasing. Operations performed a manual scram by taking the mode selector switch to shutdown. All automatic actuations and isolations occurred as designed.
The unit remained shut down in forced outage 12-02 and plant configuration changes were installed to isolate the south reactor feed pump from plant systems. The unit was restarted on July 22, 2012, increased power to 2 percent, and returned to a shutdown condition to repair a valve motor. The unit subsequently restarted on July 27, 2012, and achieved 68 percent power on July 30, 2012, using the north reactor feed pump. The licensee has not completed their root cause investigation of this event. The review of this LER cannot be completed until the root-cause evaluation is completed and the corrective actions are reviewed. Documents reviewed as part of this inspection are listed in the Attachment to this report. This LER remains open.
This event follow-up review did not constitute a sample as defined in IP 71153-05
.4 Automatic Reactor Scram Due to the Loss of the 120 kV Switchyard
a. Inspection Scope
The inspectors reviewed the plants response to an event occurring on September 14, 2012, resulting in an automatic reactor scram due to the loss of the onsite 120 kV switchyard. The loss of the 120 kV switchyard resulted in a loss of feedwater and condensate systems. The EDGs automatically started and loaded to provide electrical power to safety systems. Reactor water level decreased to 98 inches, at which point HPCI and RCIC initiated, and reactor water level was recovered. All plant systems responded accordingly with the scram. Offsite power was restored to electrical buses in a few hours. Documents reviewed in this inspection are listed in the Attachment to this report.
This event follow-up review constituted one sample as defined in IP 71153-05.
b. Findings

4OA6 Management Meetings
.1 Exit Meeting Summary
On October 11, 2012, the inspectors presented the inspection results to Mr. J. T. Conner, Site Vice President, and other members of the licensee staff. The licensee acknowledged the issues presented. The inspectors confirmed that none of the potential report input discussed was considered proprietary.
.2 Interim Exit Meetings
Interim exits were conducted for:
- The inspection results for the areas of Radiological Hazard Assessment and Exposure Controls; Occupational ALARA Planning and Controls; and RCS Specific Activity, Occupational Exposure Control Effectiveness, and RETS/ODCM Radiological Effluent Occurrences PI verification with Mr. J. T. Conner, Site Vice President, on September 14, 2012; and
- The inspection results for the Crane and heavy lift inspection with Mr. J. T. Conner, Site Vice President, on September 14, 2012.
The inspectors confirmed that none of the potential report input discussed for the Radiological Hazard Assessment and Exposure Controls; Occupational ALARA Planning and Controls; and RCS Specific Activity, Occupational Exposure Control Effectiveness, and RETS/ODCM Radiological Effluent Occurrences PI verification was considered proprietary. The inspectors confirmed that for the OpESS FY2007-003, Crane and heavy lift inspection, all paper copies of proprietary documents would be shredded and all electronic files of proprietary documents would be deleted.
4OA7 Licensee-Identified Violations
The following violation of very low significance (Green) was identified by the licensee and is a violation of NRC requirements which meets the criteria of the NRC Enforcement Policy for being dispositioned as an NCV.
- Fermi TS 5.7.1(b) for high radiation area (HRA) controls states, in part, Entry into such areasmay be made after the dose rate levels in the area have been established and personnel have been made knowledgeable of them. Contrary to the above, on April 6, 2012, two individuals entered an HRA in the torus room without being briefed on their radiological conditions. This issue was documented in the licensees corrective action program in CARD 12-22833. Immediate corrective actions included briefing the workers involved on their radiological conditions and verifying their individual accumulated radiological exposure. The finding was determined to be of very low safety significance because it was not an ALARA planning issue, there was no overexposure nor potential for overexposure, and the licensees ability to assess dose was not compromised.
