SUBJECT: EDWIN I. HATCH NUCLEAR PLANT - NRC INTEGRATED INSPECTION REPORT 05000321/2011003 AND 05000366/2011003
Dear Mr. Madison:
On June 30, 2011, U. S. Nuclear Regulatory Commission (NRC) completed an inspection at your Edwin I. Hatch Nuclear Plant, Units 1 and 2. The enclosed integrated inspection report documents the inspection results, which were discussed on July 25, 2011, with you and other members of your staff. The inspection examined activities conducted under your license as they relate to safety and compliance with the Commission's rules and regulations and with the conditions of your license. The inspectors reviewed selected procedures and records, observed activities and interviewed personnel. This report documents two NRC identified and one self-revealing finding of very low safety significance (Green). Each of these findings were determined to involve violations of NRC requirements. However, because of the very low safety significance and because they are entered into your corrective action program (CAP), the NRC is treating these findings as non-cited violations (NCV) consistent with the NRC's Enforcement Policy. If you contest any NCV, you should provide a response within 30 days of the date of this inspection report, with the basis for your denial, to the Nuclear Regulatory Commission, ATTN.: Document Control Desk, Washington DC 20555-0001, with copies to the Regional Administrator, Region II; the Director, Office of Enforcement, United States Nuclear Regulatory Commission, Washington, DC 20555-0001; and the NRC Resident Inspector at the Hatch facility.
SNC 2 In accordance with 10 CFR 2.390 of the NRC's "Rules of Practice," a copy of this letter, its enclosures, and your response (if any) will be available electronically for public inspection in the NRC Public Document Room or from the Publicly Available Records (PARS) component of the NRC's document system (ADAMS).

SUMMARY OF FINDINGS
IR 05000321/2011003, 05000366/2011003; 04/01/2011-06 /30/2011; Edwin I. Hatch Nuclear Plant, Units 1 and 2, Problem Identification and Resolution, Other Activities. The report covered a three-month period of inspection by one senior resident inspector, two resident inspectors, one reactor inspector, one senior health physicist, one senior reactor analyst, and three health physicists. Two NRC identified and one self-revealing NCV were identified and documented in this report. The significance of most findings is indicated by their color (greater than Green, or Green, White, Yellow, Red); the significance was determined using Inspection Manual Chapter (IMC) 0609, "Significance Determination Process" (SDP); the cross-cutting aspect was determined using IMC 0310, 'Components Within The Cross-Cutting Areas;' and that findings for which the SDP does not apply may be Green or be assigned a severity level after NRC management review.
Cornerstone: Mitigating Systems
- Green.
A self-revealing NCV of 10 CFR 50, Appendix B, Criterion XVI, Corrective Actions, was identified for failure to promptly identify and take corrective actions to ensure Bussmann fuses identified by the Part 21 notification 2005-37, were removed from use in safety related applications. Corrective actions taken include replacing the KTN-R 10 amp fuses on the 1B emergency diesel generator with fuses manufactured after 1991, placing a hold on all KWN-R and KTN-R fuses size 30 amps below manufactured between 1987 and 1991, and replacement of these fuses with new KWN-R and KTN-R fuses with a date code 2009 or newer. This violation has been entered into the licensee's corrective action program as condition report (CR) 2010116039. Failure to promptly identify and take corrective actions to ensure Bussmann fuses identified by the Part 21 notification 2005-37 were removed from use in safety related applications is a performance deficiency. This performance deficiency is more than minor because it is associated with the Equipment Performance attribute and adversely affected the Mitigating Systems Cornerstone objective to ensure the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. Specifically, on December 23, 2010, the Hatch 1B emergency diesel generator #3 stop circuitry operability light was discovered not illuminated on panel 1R43-P003B. Without power to this circuitry the 1B emergency diesel generator is inoperable and unavailable to provide its required safety function. The significance of this finding was screened using IMC 0609 Attachment 4, table 4a. The risk significance screening required a Phase 3 analysis, because the finding screened as potentially risk significant due to a seismic initiating event. The regional senior reactor analyst (SRA) performed a Phase 3 analysis for the finding. The analysis included two parts, the first covering the time period of total inoperability of the fuse; and the second covering the exposure time from when the non qualified fuses were installed until they were replaced, when they were subject to potential seismic failure. Calculations were performed using the NRC's plant specific risk models. The short exposure time for the first analysis, and the low likelihood of a seismic event at the plant for the second analysis, caused the combined result to be a very low risk condition. The finding was determined to be Green in the SDP.
Because the performance deficiency occurred in 2006 and is outside the past three years, no cross-cutting aspect is assigned. (Section 4OA2.2)
- Green.
An NRC-identified NCV of 10 CFR 50 Appendix B, Criterion V, Instructions, Procedures, and Drawings, was identified for failure to establish adequate procedures that address potential adverse system interactions when opening safety relief valves (SRV) without power. Immediate corrective actions taken by the licensee include changing procedure 31EO-TSG-001-0, Attachment 6, SRV Actuation Without Power to Allow Injection with Portable Pump, to ensure the SRV control circuits are isolated electrically from the direct current (DC) busses prior to installing the portable DC power supply. This violation has been entered into the licensee's corrective action program as CR 2011106008. Failure to address potential adverse system interactions when developing procedures affecting quality is a performance deficiency. This performance deficiency is more than minor because it is associated with the Procedural Quality attribute of the Mitigating Systems Cornerstone and adversely affects the cornerstone objective to ensure the availability, reliability, and capability of the safety relief valves to reduce reactor pressure in response to a loss of alternating current (AC) and DC power event. Because this finding is associated with B.5.b mitigation strategies, the finding was assessed using MC 0609 Appendix L, B.5.b Significance Determination Process, Table 2. The inspectors performed an initial screening and determined the finding did not meet the criteria listed within Table 2 for greater than Green significance therefore this finding was screened as
- Green.
Because the mitigating strategy was developed and implemented in site procedures in 2007, the performance deficiency occurred outside the past three years and no cross-cutting aspect is assigned. (Section 4OA5.3)
- Green.
An NRC-identified NCV of 10 CFR 50, Appendix B, Criterion V. Instructions, Procedures, and Drawings, was identified for failure to establish adequate procedures that address the anticipated environmental conditions when operating containment vents without power. Immediate corrective actions taken by the licensee include changing procedure 34AB-R22-003-1/2, Station Blackout, to perform preliminary actions in the torus area before high containment pressure and temperature conditions require venting. This change is intended to allow required torus area entries to be performed prior to reaching high temperature conditions in the area. This violation has been entered into the licensee's corrective action program as CR 2011105966 and CR 2011106007. Failure to address the anticipated environmental conditions when developing procedures affecting quality is a performance deficiency. This performance deficiency is more than minor because it is associated with the Procedural Quality attribute of the Mitigating Systems Cornerstone and adversely affects the cornerstone objective to ensure the availability, reliability, and capability of the containment vent valves to allow reliable pressure control of primary containment in response to a loss of AC and DC power event. This finding was assessed using MC 0609 Appendix L, B.5.b Significance Determination Process, Table 2. The inspectors performed an initial screening and determined the finding did not meet the criteria listed within Table 2 for greater than Green significance therefore this finding was screened as
- Green.
Because the procedure was developed and implemented in 2005, the performance deficiency occurred outside the past three years and no cross-cutting aspect is assigned. (Section 4OA5.3)

REACTOR SAFETY
Cornerstones: Initiating Events, Mitigating Systems, and Barrier Integrity 1R01 Adverse Weather
.1 Readiness of Offsite and Alternate AC Power Systems
a. Inspection Scope
The inspectors verified that plant features and procedures for operation and continued availability of offsite and alternate AC power systems during adverse weather were appropriate. The inspectors reviewed the licensee's procedures affecting these areas and the communications protocols between the transmission system operator (TSO) and the plant to verify that the appropriate information was being exchanged when issues arose that could impact the offsite power system. Aspects considered in the inspectors' review included:
- The coordination between the TSO and the plant during off-normal or emergency events;
- The explanations for the events;
- The estimates of when the offsite power system would be returned to a normal state; and
- The notifications from the TSO to the plant when the offsite power system was returned to normal. The inspectors also verified that plant procedures addressed measures to monitor and maintain availability and reliability of both the offsite AC power system and the onsite alternate AC power system prior to or during adverse weather conditions. Specifically, the inspectors verified that the procedures addressed the following:
- The actions to be taken when notified by the TSO that the post-trip voltage of the offsite power system at the plant would not be acceptable to assure the continued operation of the safety-related loads without transferring to the onsite power supply;
- The compensatory actions identified to be performed if it would not be possible to predict the post-trip voltage at the plant for the current grid conditions;
- A re-assessment of plant risk based on maintenance activities which could affect grid reliability, or the ability of the transmission system to provide offsite power; and
- The communications between the plant and the TSO when changes at the plant could impact the transmission system, or when the capability of the transmission system to provide adequate offsite power was challenged. Documents reviewed are listed in the Attachment. The inspectors also reviewed corrective action program items to verify that the licensee was identifying adverse weather issues at an appropriate threshold and entering them into their corrective action program in accordance with station corrective action procedures.

RADIATION SAFETY
(RS)
2RS1 Radiological Hazard Assessment and Exposure Controls
a. Inspection Scope
Hazard Assessment and Instructions to Workers During facility tours, the inspectors directly observed labeling of radioactive material and postings for radiation areas, high radiation areas (HRAs), and airborne radioactivity areas established within the radiologically controlled area (RCA) of the Unit 2 (U2) drywell and reactor building, Unit 1 (U1) and U2 control and turbine buildings, and radioactive waste (radwaste) processing and storage locations. The inspectors independently measured radiation dose rates or directly observed conduct of licensee radiation surveys for selected RCA areas. The inspectors reviewed survey records for several plant areas including surveys for alpha emitters, hot particles, airborne radioactivity, gamma surveys with a range of dose rate gradients, and pre-job surveys for upcoming tasks. The inspectors also discussed changes to plant operations that could contribute to changing radiological conditions since the last inspection. For selected outage jobs, the inspectors attended pre-job briefings and reviewed radiation work permit (RWP) details to assess communication of radiological control requirements and current radiological conditions to workers. The inspectors also walked down the Independent Spent Fuel Storage Installation (ISFSI) and independently measured radiation dose rates or directly observed conduct of licensee radiation and contamination surveys. Hazard Control and Work Practices The inspectors evaluated access barrier effectiveness for selected U1 and U2 Locked High Radiation Area (LHRA) and Very High Radiation Area (VHRA) locations. Changes to procedural guidance for LHRA and VHRA controls were discussed with health physics (HP) supervisors. Controls and their implementation for storage of irradiated material within the spent fuel pool (SFP) were reviewed and discussed in detail. Established radiological controls (including airborne controls) were evaluated for selected U2 Refueling Outage 21 (2R21) tasks including safety relief valve, N2G weld overlay activities, reactor vessel disassembly/assembly, work in reactor building HRAs, and radwaste processing and storage. In addition, licensee controls for areas where dose rates could change significantly as a result of plant shutdown and refueling operations were reviewed and discussed.
Occupational workers' adherence to selected RWPs and HP technician (HPT) proficiency in providing job coverage were evaluated through direct observations and interviews with licensee staff. Electronic dosimeter (ED) alarm set points and worker stay times were evaluated against area radiation survey results for safety relief valve work, N2G weld overlay activities, and condenser hotwell activities. ED alarm logs were reviewed and worker response to dose and dose rate alarms during selected work activities was evaluated. For HRA tasks involving significant dose rate gradients, e.g. safety relief valve and condenser hotwell activities, the inspectors evaluated the use and placement of whole body and extremity dosimetry to monitor worker exposure.
Control of Radioactive Material The inspectors observed surveys of material and personnel being released from the RCA using small article monitor, personnel contamination monitor, and portal monitor instruments. The inspectors reviewed the last two calibration records for selected release point survey instruments and discussed equipment sensitivity, alarm setpoints, and release program guidance with licensee staff.
The inspectors compared recent 10 CFR Part 61 results for the Dry Active Waste (DAW) radioactive waste stream with radionuclides used in calibration sources to evaluate the appropriateness and accuracy of release survey instrumentation. The inspectors also reviewed records of leak tests on selected sealed sources and discussed nationally tracked source transactions with licensee staff. Problem Identification and Resolution CRs associated with radiological hazard assessment and control were reviewed and assessed. The inspectors evaluated the licensee's ability to identify and resolve the issues in accordance with procedure NMP-GM-002, Corrective Action Program, Ver. 11 and NMP-GM-002-001, Corrective Action Program Instructions, Ver. 21. The inspectors also evaluated the scope of the licensee's internal audit program and reviewed recent assessment results.

ALARA planning packages were reviewed for the following high collective exposure tasks: N2G nozzle weld overlay and inspection; reactor head disassembly and re-assembly; shielding installation and removal; safety relief valve maintenance; and insulation removal. For the selected tasks, the inspectors reviewed established dose goals and discussed assumptions regarding the bases for the current estimates with responsible ALARA planners. The inspectors evaluated the incorporation of exposure reduction initiatives and operating experience, including historical post-job reviews, into RWP requirements. Day-to-day collective dose data for the selected tasks were compared with established dose estimates and evaluated against procedural criteria (trigger points) for additional ALARA review. Where applicable, changes to established estimates were discussed with ALARA planners and evaluated against work scope changes or unanticipated elevated dose rates.
Source Term Reduction and Control The inspectors reviewed the collective exposure three-year rolling average (TYRA) from 2007 - 2009 and reviewed historical collective exposure trends from 1976 - 2009. The inspectors reviewed historical dose rate trends for recirculation piping (BRAC points) and compared them to current 2R21 data. Source term reduction initiatives were reviewed and discussed with Chemistry and HP staff.
Radiation Worker Performance Radiation worker performance was observed and evaluated as part of IP 71124.01 and is documented in section 2RS1. While observing job tasks, the inspectors evaluated the use of remote technologies to reduce dose including teledosimetry and remote visual monitoring.

2RS8 Radioactive Solid Waste Processing and Radioactive Material Handling, Storage, and Transportation
a. Inspection Scope
Radioactive Material Storage The inspectors walked down indoor and outdoor areas of the Waste Separation and Temporary Storage Facility building. During the walk-down, the inspectors observed the physical condition and labeling of several storage containers, and the posting of Radioactive Material Areas. The inspectors also reviewed licensee's radwaste procedures for routine surveys and waste storage, in order to evaluate the impact of long-term storage.
Radioactive Waste System Walkdown, Characterization and Classification The inspectors walked down accessible sections of the liquid and solid radwaste systems, to assess material condition and conformance of equipment with system design diagrams. This included the indoor portion of the Radwaste Building containing storage tanks, the unused equipment area, the Radwaste Control Room, and the outdoor Resin Processing Pad Areas for Units 1 and 2. The inspectors discussed the function of radwaste components with the radwaste operator. The inspectors discussed possible changes to the radwaste processing systems with radwaste staff. The processes for the dewatering of resins, spent resin tank recirculation, resin sampling, and transfer of resins from the Processing Pads to the shipping casks and temporary storage casks were discussed with the resin processing contractor.
The inspectors reviewed the 2009 Radioactive Effluent Release Report and the 2009-2010 radionuclide characterization and classification for the DAW and dewatered resin waste streams. The inspectors evaluated analyses for hard-to-detect nuclides, reviewed the use of scaling factors, and examined quality assurance comparison results between licensee waste stream characterizations and outside laboratory data. The inspectors also evaluated how changes to plant operational parameters were taken into account in waste characterization. Shipment Preparation and Records The inspectors directly observed preparation of an intermodal shipment containing DAW in the form of scrap metal. The inspectors noted package markings and placarding, and interviewed the shipping technician regarding Department of Transportation (DOT) regulations. In addition, training records for selected individuals currently qualified to ship radioactive material were reviewed for compliance with 49 CFR Part 172 Subpart H. Six shipping records were reviewed for consistency with licensee procedures and compliance with NRC and DOT regulations.

- CR 2010113110, Delays in work activities performed during rod sequence exchanges have resulted in challenges in core management
b. Findings and Observations
Introduction:
A Green self-revealing NCV of 10 CFR 50, Appendix B, Criterion XVI, Corrective Actions, was identified for failure to promptly identify and take corrective actions to ensure Bussmann fuses identified by the Part 21 notification 2005-37, were removed from use in safety related applications.
Description:
On March 3, 2006, NRC Information Notice 2006-05, Possible Defect in Bussmannn KWN-R and KTN-R Fuses, was issued to inform licensees of a possible defect in Bussmann KWN-R and KTN-R reported to the NRC as Part 21 2005-37. The information notice states that KTN-R fuses with ratings less than or equal to 30 amps manufactured between 1987 and 1991 were potentially defective. In response to Information Notice 2006-005, the licensee initiated action item 2006202114 to procure new KTN-R fuses and replace existing KTN-R fuses currently within warehouse inventory. Actions taken under action item 2006202114 were completed in August 2006, but failed to identify all existing Part 21 KTN-R fuses within the warehouse inventory. Specifically, KTN-R 10 amp fuses purchased in 1990 and listed at the site under stock number 67142 were not removed from warehouse stock and not replaced as directed under action item 2006202114. 10 CFR 50, Appendix B, Criterion XVI, Corrective Actions, requires in part that measures shall be established to assure that conditions adverse to quality such as defective material and equipment are promptly identified and corrected. Subsequently, on May 18, 2010, under work order 1100323603 the licensee replaced ten KTN-R 10 amp fuses for the 1B emergency diesel generator control and indication circuitry with fuses purchased in 1990 and within the scope of the Bussmann Fuse Part 21. Approximately seven months later on December 23, 2010, the Hatch 1B emergency diesel generator #3 stop circuitry operability light was discovered not illuminated on panel 1R43-P003B due to the failure of a Bussmann KTN-R 10 amp fuse. Without power to this circuitry the 1B emergency diesel generator is inoperable and unavailable. Specifically, because of the loss of power, the permissive in the #3 circuitry does not change state to de-energize the 1B emergency diesel generator "shutdown relay"; therefore, seven seconds after an initial start the diesel would trip because of its "shutdown relay" remaining energized. Additionally, this failure would also prevent the DC system from energizing the generator excitation control circuitry which would prevent the diesel from providing power to the emergency bus. Hatch CR 2010116039 was initiated to document and investigate this failure. The failed fuse was sent to Wyle labs for dissection and it was confirmed by Wyle labs in failure analysis report 58240R11 that the fuse failure was caused by the manufacturing soldering issues identified in the Bussmann Fuse Part 21. Corrective actions taken under CR 2010116039 included replacing the KTN-R 10 amp fuses on the 1B emergency diesel generator with fuses manufactured after 1991, placing a hold on all KWN-R and KTN-R fuses size 30 amps below manufactured between 1987 and 1991 and replacement of these fuses with new KWN-R and KTN-R fuses with a date code 2009 or newer.
Analysis:
Failure to promptly identify and take corrective actions to ensure Bussmann fuses identified by the Part 21 notification 2005-37, were removed from use in safety related applications is a performance deficiency. This performance deficiency is more than minor because it is associated with the Equipment Performance attribute and adversely affected the Mitigating Systems Cornerstone objective to ensure the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. Specifically, on December 23, 2010, the Hatch 1B emergency diesel generator #3 stop circuitry operability light was discovered not illuminated on panel 1R43-P003B. Without power to this circuitry the 1B emergency diesel generator is inoperable and unavailable to provide its required safety function. The significance of this finding was screened using IMC 0609 Attachment 4, table 4a.
The risk significance screening required a Phase 3 analysis, because the finding screened as potentially risk significant due to a seismic initiating event. The regional SRA performed a Phase 3 analysis for the finding. The analysis included two parts, the first covering the time period of total inoperability of the fuse; and the second covering the exposure time from when the non qualified fuses were installed until they were replaced, when they were subject to potential seismic failure. Calculations were performed using the NRC's plant specific risk models. The short exposure time for the first analysis, and the low likelihood of a seismic event at the plant for the second analysis, caused the combined result to be a very low risk condition. The finding was determined to be Green in the SDP. Because the performance deficiency occurred in 2006 and is outside the past three years, no cross-cutting aspect is assigned.
Enforcement:
10 CFR 50, Appendix B, Criterion XVI, Corrective Actions, requires in part that measures shall be established to assure that conditions adverse to quality such as defective material and equipment are promptly identified and corrected. Contrary to the above from August 2006 to December 2010 the licensee failed to promptly identify and take corrective actions to ensure defective material identified by the Bussmann Fuse Part 21 notification 2005-37, was removed from use in safety related applications. Specifically, KTN-R 10 amp fuses purchased in 1990 and listed at the site under stock number 67142 were not removed from warehouse stock and not replaced as directed under action item 2006202114. Immediate corrective actions taken by the licensee include replacing the KTN-R 10 amp fuses on the 1B emergency diesel generator with fuses manufactured after 1991, placing a hold on all KWN-R and KTN-R fuses size 30 amps below manufactured between 1987 and 1991, and replacement of these fuses with new KWN-R and KTN-R fuses with a date code 2009 or newer. Because this violation was of very low safety significance and it was entered into the licensee's corrective actions program as CR 2010116039, this violation is being treated as an NCV, consistent with the Enforcement Policy. NCV 05000321,366/2011003-01, "Failure to promptly identify and take corrective actions to ensure Bussmann fuses identified by the Part 21 notification 2005-37, were removed from use in safety related applications."
.3 Semi-Annual Trend Review
a. Inspection Scope
The inspectors performed a review of the licensee's corrective action program and associated documents to identify trends which could indicate the existence of a more significant safety issue. The review was focused on repetitive equipment issues, but also considered the results of inspector daily CR screening, licensee trending efforts, and licensee human performance results. The review nominally considered the six month period of January 2011 through June 2011 although some examples extended beyond those dates when the scope of the trend warranted. The inspectors compared and contrasted their results with the results contained in the licensee's quarterly trend reports. Corrective actions associated with a sample of the issues identified in the licensee's trend reports were reviewed for adequacy. The inspectors also evaluated the trend reports against the requirements of the licensee's corrective action program as specified in licensee procedure NMP-GM-002, and 10 CFR 50, Appendix B. Documents reviewed are listed in the Attachment.
b. Findings and Observations
No findings were identified.
4OA5 Other Activities

.3 (Closed) NRC Temporary Instruction 2515/183, "Follow-up to the Fukushima Daiichi Nuclear Station Fuel Damage Event"
a. Inspection Scope
The inspectors assessed the activities and actions taken by the licensee to assess its readiness to respond to an event similar to the Fukushima Daiichi nuclear plant fuel damage event. This included (1) an assessment of the licensee's capability to mitigate conditions that may result from beyond design basis events, with a particular emphasis on strategies related to the spent fuel pool, as required by NRC Security Order Section B.5.b, issued February 25, 2002, as committed to in severe accident management guidelines, and as required by 10 CFR 50.54(hh); (2) an assessment of the licensee's capability to mitigate station blackout (SBO) conditions, as required by 10 CFR 50.63, and station design bases; (3) an assessment of the licensee's capability to mitigate internal and external flooding events, as required by station design bases; and (4) an assessment of the thoroughness of the walkdowns and inspections of important equipment needed to mitigate fire and flood events, which were performed by the licensee to identify any potential loss of function of this equipment during seismic events possible for the site.
b. Findings
Inspection Report 05000321,366/2011010 (ML111330108) documented detailed results of this inspection activity. Following issuance of the report, the inspectors conducted detailed follow-up on selected issues. The following findings were identified during this follow-up inspection:
Introduction:
A Green NRC-identified NCV of 10 CFR 50 Appendix B, Criterion V. Instructions, Procedures, and Drawings, was identified for failure to establish adequate procedures that address potential adverse system interactions when opening safety relief valves without power.
Description:
During performance of TI-183, the inspectors questioned the ability of the licensee to perform procedure 31EO-TSG-001-0, Technical Support Guidelines, Attachment 6, SRV Actuation Without Power to Allow Injection with Portable Pump, as written. This procedure was implemented by the licensee in July 2007 and installs a portable DC power supply to locally energize and operate the safety relief valves when on site electrical power is unavailable. The procedure for operating SRV's without power is written such that the safety relief valves control circuits are not verified to be electrically isolated from the stations DC distribution system prior to installing a portable DC power supply. The portable DC power supply does not have the electrical capacity to supply power to the SRV's and to back feed the station's DC busses. Therefore if the SRV's remained electrically connected to the stations DC busses the portable DC power supply would not produce sufficient voltage to energize the SRV solenoids resulting in the SRV's failing to open. In this case the SRV's would periodically lift at their mechanical relief setpoint of 1150 +/- 34.5 psig. With the reactor pressure vessel (RPV) at this high pressure and no high pressure injection cooling available, reactor coolant inventory lost could not be made up by the low pressure portable pump. This would ultimately result in the core becoming uncovered and subsequent fuel damage. This issue was entered into the licensee's corrective actions program as CR 2011106008.
The licensee was able to demonstrate to the inspectors that, although the possibility exists for the portable DC power supply to fail to open SRV's due to the backfeed condition, due to self protecting features the DC power supply would not be damaged and there is a high likelihood the licensee would be able to identify and correct the backfeed circuit prior to the core becoming uncovered.
Analysis:
Failure to consider potential adverse system interactions when developing procedures affecting quality is a performance deficiency. This performance deficiency is more than minor because it is associated with the Procedural Quality attribute of the Mitigating Systems Cornerstone and adversely affects the cornerstone objective to ensure the availability, reliability, and capability of the safety relief valves to reduce reactor pressure in response to a loss of AC and DC power event. Because this finding is associated with B.5.b mitigation strategies, the finding was assessed using MC 0609 Appendix L, B.5.b Significance Determination Process, Table 2. The inspectors performed an initial screening and determined the finding did not meet the criteria listed within Table 2 for greater than Green significance, therefore this finding was screened as Green. Because the mitigating strategy was developed and implemented in site procedures in 2007 the performance deficiency occurred outside the past three years and no cross-cutting aspect is assigned.
Enforcement:
10 CFR 50, Appendix B, Criterion V. Instructions, Procedures, and Drawings, requires in part that activities affecting quality shall be prescribed by procedures appropriate to the circumstances. Contrary to the above from July 2007 to June 2011 the licensee failed to prescribe within procedure 31EO-TSG-001-0, Technical Support Guidelines, Attachment 6, SRV Actuation Without Power to Allow Injection with Portable Pump, the potential adverse system interactions when operating SRV's with a portable DC power supply, which is an activity affecting quality. Immediate corrective actions taken by the licensee include changing 31EO-TSG-001-0, Attachment 6, SRV Actuation Without Power to Allow Injection with Portable Pump, to ensure the SRV control circuits are isolated electrically from the DC busses prior to installing the portable DC power supply. Because this violation was of very low safety significance and it was entered into the licensee's corrective actions program as CR 2011106008, this violation is being treated as an NCV, consistent with the Enforcement Policy. NCV 05000321,366/2011003-02, "Failure to consider potential adverse system interactions when developing procedure to open SRV's without power."
Introduction:
A Green NRC-identified NCV of 10 CFR 50, Appendix B, Criterion V. Instructions, Procedures, and Drawings, was identified for failure to establish adequate procedures that address the anticipated environmental conditions when operating containment vents without power.
Description:
During performance of TI-183, the inspectors questioned whether the manual operation of the containment vent procedure, 31EO-TSG-001-0, Attachment 10, Manually Open Containment Vent Lines, could be performed as written. This procedure was implemented by the licensee in September 2005 and has operators manually operate vent valves to relieve pressure inside primary containment during a loss of AC and DC power event. The inspectors determined this procedure did not take into account anticipated environmental conditions within the areas operators would enter during performance of portions of this procedure. Under some scenarios this procedure may not be able to be performed due to the high ambient temperature conditions expected to be present within the area operators would be required to enter to install rigs and operate dampers. During a loss of AC and DC power condition, reactor decay heat would be transferred from the reactor to the torus suppression pool through the safety relief valves. The suppression pool will heat up, reach saturation conditions, and cause pressure within the primary containment to increase. The licensee's emergency operating procedures and severe accident guidelines direct the venting of the torus before the primary containment pressure limit is exceeded. The primary containment pressure limit maximum acceptable torus pressure would require torus venting prior to exceeding 60 psig. Utilizing ASME Steam Tables, for a 60 psig pressure (74.7 psia) the saturation temperature is ~307 degrees F. Should the licensee vent containment at a torus pressure as low as 40 psig (54.7 psia) the saturation temperature is still ~285 degrees F. Attachment 10 directs operators to perform numerous strenuous and complicated tasks within the torus area. Among the actions operators would perform include 1) transferring several air bottles down vertical ladders to the torus area, 2) disconnecting fittings and connecting temporary air lines to three dampers while standing directly on top of the un-lagged metal shell of the saturated torus, and 3) periodically operating the three dampers using air cylinders while maintaining radio contact to control primary containment pressure. This evolution would be performed in very low light conditions using portable battery operated lighting (flashlights) due to the loss of power to installed area lighting. These conditions would hinder performance and require increased time within the high temperature environment to complete the Attachment 10 procedure. The inability to vent primary containment during a loss of AC and DC power utilizing the containment vent valves could result in the over pressurization and subsequent failure of primary containment. To address this issue the licensee initiated CR's 2011105966 and 2011106007. The licensee has changed procedure 34AB-R22-003-1/2, Station Blackout, to perform preliminary actions in the torus area before the high containment pressure conditions require venting. This change is intended to allow required torus area entries to be performed prior to the time when high temperature saturation conditions are reached inside the torus.
Analysis:
Failure to address the anticipated environmental conditions when developing procedures affecting quality is a performance deficiency. This performance deficiency is more than minor because it is associated with the Procedural Quality attribute of the Mitigating Systems Cornerstone and adversely affects the cornerstone objective to ensure the availability, reliability, and capability of the containment vent valves to allow reliable primary containment pressure control in response to a loss of AC and DC power event. This finding was assessed using MC 0609 Appendix L, B.5.b Significance Determination Process, Table 2. The inspectors performed an initial screening and determined the finding did not meet the criteria listed within Table 2 for greater than Green significance therefore this finding was screened as Green. Because the procedure was developed and implemented in 2005, the performance deficiency occurred outside the past three years and no cross-cutting aspect is assigned.
Enforcement:
10 CFR 50, Appendix B, Criterion V. Instructions, Procedures, and Drawings, requires in part that activities affecting quality shall be prescribed by procedures appropriate to the circumstances. Contrary to the above from September 2005 through June 2011 the licensee failed to prescribe within procedures the appropriate circumstances of considering the environmental conditions within the torus area for manually operating containment vent valves, which is an activity affecting quality. Specifically, procedures did not address operation of the vent valves in an anticipated high temperature condition. Immediate corrective actions taken by the licensee include changing procedure 34AB-R22-003-1/2, Station Blackout, to perform preliminary actions in the torus area before high torus temperature conditions are reached. Because this violation was of very low safety significance and it was entered into the licensee's corrective actions program as CR 2011105966 and CR 2011106007, this violation is being treated as an NCV, consistent with the Enforcement Policy. NCV 05000321,366/2011003-03, "Failure to address the anticipated environmental conditions when developing procedures to manually operate containment vent valves."
.4 (Closed) NRC Temporary Instruction 2515/184, "Availability and Readiness Inspection of Severe Accident Management Guidelines (SAMGs)"
On May 27, 2011, the inspectors completed a review of the licensee's severe accident management guidelines (SAMGs), implemented as a voluntary industry initiative in the 1990's, to determine (1) whether the SAMGs were available and updated, (2) whether the licensee had procedures and processes in place to control and update its SAMGs, (3) the nature and extent of the licensee's training of personnel on the use of SAMGs, and (4) licensee personnel's familiarity with SAMG implementation.
The results of this review were provided to the NRC task force chartered by the Executive Director for Operations to conduct a near-term evaluation of the need for agency actions following the Fukushima Daiichi fuel damage event in Japan. Plant-specific results for E.I. Hatch Station were provided as an Enclosure to a memorandum to the Chief, Reactor Inspection Branch, Division of Inspection and Regional Support, dated June 02, 2011 (ML111530328).
4OA6 Meetings, Including Exit
On June 25, 2011, the resident inspectors presented the inspection results to you and other members of your staff. The inspectors confirmed that proprietary information was not provided or examined during the inspection.
