SUBJECT: GRAND GULF NUCLEAR STATION - NRC INTEGRATED INSPECTION REPORT 05000416/2008004
Dear Mr. Douet:
On September 20, 2008 the U.S. Nuclear Regulatory Commission (NRC) completed an integrated inspection at your Grand Gulf Nuclear Station. The enclosed report documents the inspection results, which were discussed on September 29, 2008, 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.
One violation is cited in the enclosed Notice of Violation and the circumstances surrounding this violation are described in detail in the enclosed report. The violation involved your failure to perform an adequate inspection of probable maximum precipitation door seals protecting safety-related equipment (EA-08-295). Although determined to be of very low safety significance (Green), this violation is being cited because not all the criteria specified in Section VI.A.1 of the NRC Enforcement Policy for a noncited violation were satisfied. Specifically, Grand Gulf Nuclear Station failed to restore compliance within a reasonable time after the violation was first identified in NRC Inspection Report 05000416/2008002. Please note that you are required to respond to this letter and should follow the instructions specified in the enclosed Notice when preparing your response. The NRC will use your response, in part, to determine whether further enforcement action is necessary to ensure compliance with regulatory requirements. This report documents two additional NRC identified findings of very low safety significance (Green). Both of these findings were determined to involve violations of NRC requirements. However, because of the very low safety significance and because they were entered into your corrective action program, the NRC is treating these findings as noncited violations consistent with Section VI.A.1 of the NRC Enforcement Policy. If you contest the subject or severity of a noncited violation, 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 Entergy Operations, Inc. - 2 -

SUMMARY OF FINDINGS
IR 05000416/2008004; 6/22/2008 - 9/21/2008; Grand Gulf Nuclear Station; Maintenance Effectiveness, Maintenance Risk Assessments and Emergent Work Control, and Problem Identification and Resolution. This report covers a 3-month period of inspection by resident inspectors and announced baseline inspections by regional inspectors. Three Green findings were identified by the inspectors. One of findings was cited violation and two were noncited violations.
The significance of most findings is indicated by their color (Green, White, Yellow, Red) using Inspection Manual Chapter 0609, "Significance Determination Process." Findings for which the significance determination process does not apply may be Green or be assigned a severity level after NRC management review. The NRC's program for overseeing the safe operation of commercial nuclear power reactors is described in NUREG-1649, "Reactor Oversight Process," Revision 4, dated December 2006.
A. NRC-Identified and Self-Revealing Findings
Cornerstone: Mitigating Systems
- Green.
The inspectors identified a Green noncited violation of 10 CFR 50.65(a)(2) involving the failure to adequately monitor the performance of four Maintenance Rule systems. Several discrepancies in the Maintenance Rule Program were discovered by the inspectors, including unevaluated condition monitoring failures in the neutron monitoring system and an unevaluated functional failure in the standby gas treatment system. Plant personnel implemented additional corrective actions to fully investigate the potential extent of this condition and the apparent weakness in the condition report screening process used for the Maintenance Rule program. As a result, the Maintenance Rule expert panel classified four systems as needing increased monitoring and goal setting, moving these systems from an a(2) to an a(1) status. The licensee entered this issue into the corrective action program as Condition Report CR-GGN-2008-02219.
This finding is more than minor since it was similar to Inspection Manual Chapter 0612, Appendix E, Example 7.b in that the problem involved degraded equipment performance. This finding was characterized under the significance determination process as having very low safety significance because the maintenance rule aspect of the finding did not cause an actual loss of safety function of the system nor did it cause a component to be inoperable. The cause of this finding has a crosscutting aspect in the area of human performance associated with work practices because licensee personnel failed to use proper self-checking and peer-checking to identify repetitive maintenance rule functional failures and also failed to properly document condition report screening activities H.4(a) (Section 1R12).
- Green.
The inspectors identified a Green noncited violation of 10 CFR 50.65 (a)(4), involving the failure to perform risk assessments following multiple declared tornado watches affecting Grand Gulf Nuclear Station during the landfall of Hurricane Gustav. On the morning of September 3, 2008, the inspectors noted that the licensee had not evaluated the increased risk from a declared tornado watch for the Claiborne County area. The inspectors brought this to the attention of plant personnel and a risk assessment was performed and plant risk was changed from a 'Green' to a 'Yellow' risk condition. The inspectors then reviewed the tornado watches declared by the National Weather Service that affected Claiborne County during the landfall of Hurricane Gustav, and noted that six separate tornado watches had been declared over the previous three days. A review of the control room logs showed no documentation of changes in plant risk condition. The licensee entered this issue into the corrective action program as Condition Report CR-GGN-2008-04397.
This finding is more than minor because the risk assessments failed to consider unusual external conditions that were present or imminent. Using Manual Chapter 0609, Appendix K, "Maintenance Risk Assessment and Risk Management Significance Determination Process," Flowchart 1, "Assessment of Risk Deficit" and consulting with the regional senior risk analyst, the inspectors determined the finding of very low safety significance due to a calculated incremental core damage probability deficit of 4.38E-08. This finding has a crosscutting aspect in the area of human performance associated with work practices in that plant personnel failed to follow the risk management procedure H.4(b) (Section 1R13).
- Green.
The inspectors identified a Green cited violation of 10 CFR Part 50 Appendix B, Criterion V, "Instructions, Procedures, and Drawings," involving the failure to perform an adequate inspection of probable maximum precipitation door seals protecting safety related equipment. The licensee had previously received a noncited violation for inadequate inspections of probable maximum precipitation door seals in NRC Inspection Report 05000416/2008002. On July 9, 2008, the inspectors found the entrance door to the Train B standby service water pump house not meeting the standards of the maintenance procedure because the door seals failed to make contact with the door.
The extent of condition review found seven additional door seals degraded, including the doors to the diesel generator building and control building. The door seal on the Train B standby service water pump house identified by the inspectors on July 9, 2008, had not been identified by plant personnel during an extent of condition review on February 29, 2008. The licensee entered this issue into the corrective action program as Condition Report CR-GGN-2008-03216.
The finding is more than minor since it affects the protection against external factors attribute of mitigating system cornerstone. The door seals also represent a degrading condition that if left uncorrected could affect the availability, reliability, and capability of mitigating systems required to respond to initiating events to prevent undesirable consequences. Using the Manual Chapter 0609, "Significance Determination Process," Phase 1 Worksheet, the inspectors used the seismic, flooding, and severe weather Table 4b and determined it would affect multi-trains of safety equipment. The inspectors consulted the regional senior reactor analyst, who performed a Phase 3 analysis using many bounding and conservative assumptions. The result was a delta-CDF of 3.3E-7/yr and a delta-LERF of 6.6E-8/yr. These results confirmed that the finding had very low safety significance (Green). The cause of this finding has a crosscutting aspect in the area of problem identification and resolution in that the licensee failed to take adequate corrective actions to ensure degraded probable maximum precipitation door seals were properly evaluated and repaired in a timely manner P.1(d) (Section 4OA2).
B. Licensee-Identified Violations
None.

.2 Readiness For Impending Adverse Weather Condition - Hurricane Gustav which Produced High Wind Conditions, and Tornado Watches/Warnings for the Site
a. Inspection Scope
Since Hurricane Gustav, with potential tornados and high winds, was forecast in the vicinity of the facility for September 1 , 2008, the inspectors reviewed the overall preparations and protections for the expected weather conditions. Starting on August 26, 2008, the inspectors walked down the site standby service water cooling towers and pump houses, in addition to the emergency AC power systems, because their safety-related functions could be affected or required as a result of the hurricane high winds or tornado-generated missiles or the loss of offsite power. The inspectors evaluated the plant staff's preparations against the site's procedures and determined that the staff's actions were adequate. During the inspection, the inspectors focused on plant specific design features and procedures used to respond to specified adverse weather conditions. The inspectors also toured the plant grounds to look for any loose debris that could become missiles during a tornado. The inspectors evaluated operator staffing and accessibility of controls and indications for those systems required to control the plant. Additionally, the inspectors reviewed the UFSAR and performance requirements for systems selected for inspection, and verified that operator actions were appropriate as specified by plant specific procedures. The inspectors also reviewed a sample of corrective action program items to verify that the identified adverse weather issues at an appropriate threshold and dispositioned them through the corrective action program in accordance with station corrective action procedures. Specific documents reviewed during this inspection are listed in the attachment. This inspection constitutes one readiness for impending adverse weather condition sample as defined in Inspection Procedure 71111.01-05.
b. Findings
No findings of significance were identified.
1R04 Equipment Alignment
.1 Quarterly Partial System Walkdowns
a. Inspection Scope
The inspectors performed partial system walkdowns of the following risk-significant systems:
- July 29, 2008, the inspectors walked down the control room air conditioning (CRAC) Train B and standby fresh air (SBFA) Train B during planned outage on CRAC Train A and SBFA Train A ENCLOSURE 2
- September 15, 2008, the inspectors walked down the Division I standby diesel generator during a planned outage of the Division II standby diesel generator 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, Administrative TS, outstanding work orders, 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 that there were no obvious deficiencies. The inspectors also verified that 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. These activities constituted two partial system walkdown samples as defined by Inspection Procedure 71111.04-05.
b. Findings
No findings of significance were identified.
.2 Semi-Annual Complete System Walkdown
a. Inspection Scope
On June 24, 2008, the inspectors completed a system alignment inspection of the high pressure core spray system to verify the functional capability of the system. This system was selected because it was considered both safety-significant and risk-significant in the licensee's probabilistic risk assessment. The inspectors walked down the system to review mechanical and electrical equipment line ups, electrical power availability, system pressure and temperature indications, as appropriate, component labeling, component lubrication, component and equipment cooling, hangers and supports, operability of support systems, and to ensure that ancillary equipment or debris did not interfere with equipment operation. A review of a sample of past and outstanding work orders (WOs) was performed to determine whether any deficiencies significantly affected the system function. In addition, the inspectors reviewed the corrective action program (CAP)database to ensure that system equipment alignment problems were being identified and appropriately resolved. The documents used for the walkdown and issue review are listed in the attachment. These activities constituted one complete system walkdown sample as defined by Inspection Procedure 71111.04-05.
ENCLOSURE 2
b. Findings
No findings of significance were identified.
1R05 Fire Protection
.1 Routine Resident Inspector Tours
a. Inspection Scope
The inspectors conducted fire protection walkdowns which were focused on availability, accessibility, and the condition of firefighting equipment in the following risk-significant plant areas:
- Division II Diesel Generator Room (Room 1D303)
- High Pressure Core Spray Room (Room 1A109) and Residual Heat Removal Train B Pipe Penetration Room (Room 1A205)
- Service Water Train B Pump House and Valve Room (Rooms 2M110 and 2M112)
- Auxiliary Building 208' and 245' elevations (Rooms 1A532, 1A602, 1A603, 1A604 and 1A605)
- Control Building HVAC areas (Rooms OC302 and OC303)
- Containment Building 135' elevation (1A311 and 1A313) 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 had implemented adequate compensatory measures for out of service, degraded or inoperable fire protection equipment, systems, or features in accordance with the licensee's fire plan.
The inspectors selected fire areas based on their overall contribution to internal fire risk as documented in the plant's 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 plant's ability to respond to a security event. Using the documents listed in the attachment, the inspectors verified that fire hoses and extinguishers were in their designated locations and available for immediate use; that fire detectors and sprinklers were unobstructed, that transient material loading was within the analyzed limits; and fire doors, dampers, and penetration seals appeared to be in satisfactory condition. The inspectors also verified that minor issues identified during the inspection were entered into the licensee's corrective action program. These activities constituted six quarterly fire protection inspection samples as defined by Inspection Procedure 71111.05-05.
ENCLOSURE 2
b. Findings
No findings of significance were identified.
1R06 Flooding
.1 Internal Flooding
a. Inspection Scope
The inspectors reviewed selected risk important plant design features and licensee procedures intended to protect the plant and its safety related equipment from internal flooding events. The inspectors reviewed flood analyses and design documents, including the UFSAR, engineering calculations, and abnormal operating procedures for licensee commitments. The specific documents reviewed are listed in the attachment. In addition, the inspectors reviewed licensee drawings to identify areas and equipment that may be affected by internal flooding caused by the failure or misalignment of nearby sources of water, such as the fire suppression or the circulating water systems. The inspectors also reviewed the licensee's corrective action documents with respect to past flood-related items identified in the corrective action program to verify the adequacy of the corrective actions. The inspectors performed a walkdown of the following plant areas to assess the adequacy of watertight doors and verify drains and sumps were clear of debris and were operable, and that the licensee complied with its commitments:
- Low Pressure Core Spray Room
- RHR Train C Pump Room This inspection constitutes one internal flooding sample as defined in Inspection Procedure 71111.06-05.
b. Findings
No findings of significance were identified.
1R11 Licensed Operator Requalification Program
.1 Resident Inspector Quarterly Review
a. Inspection Scope
On July 2, 2008, the inspectors observed a crew of licensed operators in the plant's simulator during licensed operator requalification examinations to verify that operator performance was adequate, evaluators were identifying and documenting crew performance problems and training was being conducted in accordance with licensee procedures. The inspectors evaluated the following areas:
- Licensed operator performance ENCLOSURE 2
- Crew's clarity and formality of communications
- Ability to take timely actions in the conservative direction
- Prioritization, interpretation, and verification of annunciator alarms
- Correct use and implementation of abnormal and emergency procedures
- Control board manipulations

a. Inspection Scope
The inspectors evaluated degraded performance issues involving the following risk significant systems:
- Emergency Switchgear and Battery Room Ventilation System (Z77)
- Riley Temperature switches for various safety related systems (E31, T46, X77, and Y47) The inspectors reviewed events such as where ineffective equipment maintenance has resulted in valid or invalid automatic actuations of engineered safeguards systems and independently verified the licensee's actions to address system performance or condition problems in terms of the following:
- Implementing appropriate work practices
- Identifying and addressing common cause failures
- Scoping of systems in accordance with 10 CFR 50.65(b) of the maintenance rule ENCLOSURE 2
- Characterizing system reliability issues for performance
- Charging unavailability for performance
- Trending key parameters for condition monitoring
- Ensuring 10 CFR 50.65(a)(1) or (a)(2) classification or reclassification
- Verifying appropriate performance criteria for structures, systems, and components (SSCs)/functions classified as (a)(2) or appropriate and adequate goals and corrective actions for systems classified as (a)(1) The inspectors assessed performance issues with respect to the reliability, availability, and condition monitoring of the system. In addition, the inspectors verified maintenance effectiveness issues were entered into the corrective action program with the appropriate significance characterization. Documents reviewed are listed in the attachment. This inspection constitutes two quarterly maintenance effectiveness samples as defined in Inspection Procedure 71111.12-05.
b. Findings
Introduction.
The inspectors identified a Green noncited violation (NCV) of 10 CFR 50.65(a)(2) involving the failure to adequately monitor the performance of four maintenance rule scoped systems.
Description.
In April 2008, the inspectors identified several discrepancies in the maintenance rule program, including several unevaluated condition monitoring failures in the neutron monitoring system and an unevaluated functional failure in the standby gas treatment system. In addition, the inspectors discovered several condition reports documenting equipment issues that had no functional failure evaluations. Due to the absence of documented evidence to determine how these events were erroneously screened or overlooked in the routine condition reports screening process, plant personnel implemented additional corrective actions to fully investigate the potential extent of this condition and the apparent weakness in the condition reports screening process used for the GGNS Maintenance Rule Program. During this review, several maintenance rule scoped systems were identified as having repetitive component failures of Riley temperature switches that spanned multiple systems. These systems included the electrical switchgear and battery room ventilation system, the diesel generator building ventilation system, and the standby service water pump house ventilation system. Further review also identified a repetitive functional failure of an Asco solenoid valve in the emergency switchgear and battery room ventilation system.
As a result, the maintenance rule expert panel classified these systems as needing increased monitoring and goal setting, moving these systems from an a(2) to an a(1) status.
Analysis.
The inspectors determined that the finding is a performance deficiency in that the licensee failed to apply goals and increase the monitoring of systems impacted by repetitive component failures. The finding was more than minor because it was similar to Inspection Manual Chapter 0612, Appendix E, Example 7.b, in that the problem involved degraded equipment performance. This finding was characterized under the ENCLOSURE 2 significance determination process as having very low safety significance because the maintenance rule aspect of the finding did not cause an actual loss of safety function of the system nor did it cause a component to be inoperable. The cause of this finding has a crosscutting aspect in the area of human performance associated with work practices because licensee personnel failed to use proper self-checking and peer-checking to identify repetitive maintenance rule functional failures and also failed to properly document condition report screening activities H.4(a).
Enforcement.
10 CFR Part 50.65(a)(1) requires, in part, that licensees shall monitor the performance or condition of systems, structures and components (SSCs) within the scope of the rule against licensee-established goals in a manner sufficient to provide reasonable assurance the SSCs are capable of fulfilling their intended safety functions.
10 CFR Part 50.65(a)(2) requires, in part, that the monitoring specified in paragraph (a)(1) is not required where it has been demonstrated the performance or condition of an SSC is being effectively controlled through the performance of appropriate preventive maintenance such that the SSC remains capable of performing its intended function. Contrary to the above, the licensee failed to demonstrate that the performance or condition of four maintenance rule scoped systems had been effectively controlled through the performance of appropriate preventive maintenance. Specifically, the licensee failed to properly evaluate the repetitive failures of system components which demonstrated that the performance of the systems were not being effectively controlled and goal setting and monitoring was required. However, because this inspection finding was characterized by the Significance Determination Process as having very low risk significance (Green) and has been entered in the licensee's CAP as CR-GGN-2008-02219, this violation is being treated as an NCV, consistent with Section IV.A.1 of the NRC Enforcement Policy: NCV 05000416/2008004-01, Failure to Monitor Performance of Four Maintenance Rule Systems.
1R13 Maintenance Risk Assessments and Emergent Work Control
.1 Maintenance Risk Assessments and Emergent Work Control
a. Inspection Scope
The inspectors reviewed the licensee's evaluation and management of plant risk for the maintenance and emergent work activities affecting risk-significant and safety-related equipment listed below to verify that the appropriate risk assessments were performed prior to removing equipment for work:
- Division 2 diesel generator out of service due pre-modification work on July 10, 2008
- Reactor protection system Train B work the week of July 21, 2008
- Tornado watch including Claiborne County on September 3, 2008
- Division 1 diesel generator out of service due to lube oil leak on September 9, 2008 and site entering orange risk due to tornado warning in the area on September 13, 2008 ENCLOSURE 2 These activities were selected based on their potential risk significance relative to the reactor safety cornerstones. As applicable for each activity, the inspectors verified that 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 that 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. These activities constituted four samples as defined by Inspection Procedure 71111.13-05.
b. Findings
Introduction.
The inspectors identified a Green noncited violation of 10 CFR 50.65(a)(4) involving the failure to perform risk assessments following multiple declared tornado watches affecting Grand Gulf Nuclear Station during the landfall of Hurricane Gustav.
Description.
On the morning of September 3, 2008, the inspectors noted that the licensee had not evaluated the increased risk from a declared tornado watch for the Claiborne county area. The inspector brought this to the attention of plant personnel and a risk assessment was performed and plant risk was changed from a 'Green' to a 'Yellow' risk condition. The inspectors then reviewed the tornado watches declared by the National Weather Service that affected Claiborne County during the landfall of Hurricane Gustav, and noted the following six separate tornado watches had been declared over the previous three days:
- Tornado Watch 878 at 1550 on 9/1/2008
- Tornado Watch 880 at 2345 on 9/1/2008
- Tornado Watch 881 at 0635 on 9/2/2008
- Tornado Watch 882 at 1550 on 9/2/2008
- Tornado Watch 884 at 2340 on 9/2/2008
- Tornado Watch 885 at 0620 on 9/3/2008 A review of the control room logs showed no documentation of changes in plant risk condition. The inspector questioned operations personnel and determined that no risk evaluations had been completed.
Analysis.
The inspectors determined that the finding is a performance deficiency because the licensee failed to perform risk assessments involving changing environmental conditions that could have negatively impacted offsite power availability. Per Manual Chapter 0612, Appendix B, the deficiency was greater than minor because the risk assessments failed to consider unusual external conditions that are present or imminent. Using Manual Chapter 0609, Appendix K, "Maintenance Risk Assessment ENCLOSURE 2 and Risk Management Significance Determination Process," Flowchart 1, "Assessment of Risk Deficit" and consulting with the regional senior reactor analyst, the inspectors determined the finding of very low safety significance due to a calculated incremental core damage probability deficit of 4.38E-08. This finding has a crosscutting aspect in the area of human performance associated with work practices in that plant personnel failed to follow the risk management procedure H.4(b).
Enforcement.
10 CFR 50.65 (a)(4), states that, before performing maintenance activities (including but not limited to surveillance, postmaintenance testing, and corrective and preventive maintenance), the licensee shall assess and manage the increase in risk that may result from the proposed maintenance activities. Contrary to the above, the inspectors identified that, on several occasions, plant personnel failed to assess and mange risk from proposed maintenance activities during unusual external conditions (i.e., severe weather). Because this finding is characterized by the Significance Determination Process as having very low risk significance (Green) and has been entered into the licensee's CAP as CR-GGN-2008-04397, this violation is being treated as an NCV, consistent with Section VI.A of the Enforcement Policy: NCV 05000416/2008004-02, Failure to Perform an Adequate Risk Assessment during Adverse Weather Conditions.
1R15 Operability Evaluations
.1 Operability Evaluations
a. Inspection Scope
The inspectors reviewed the following issues:
- CR-GGN-2008-02819, Residual heat removal Pump A failed to start due to failure to properly rack breaker
- CR-GGN-2008-03584, Containment penetration not drained of water prior to performing pneumatic containment isolation valve local leak rate testing
- CR-GGN-2008-03854, Leading edge flow meter (LEFM) out of service due to Meter 1 pathways #1 and #8 signal reject rate exceeded
- CR-GGN-2008-04271, Standby service water pump house ventilation screens found in a degraded condition
- CR-GGN-2008-04505, Division 3 battery bank having a loose connection on the positive lead on battery cell number one
- CR-GGN-2008-04121, Reactor core isolation cooling steam bypass valve packing leak 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 that 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 ENCLOSURE 2 appropriate sections of the TS and Updated Safety Analysis Report (USAR) to the licensee's 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 also reviewed a sampling of corrective action documents to verify that the licensee was identifying and correcting any deficiencies associated with operability evaluations. Documents reviewed are listed in the attachment. This inspection constitutes six samples as defined in Inspection Procedure 71111.15-05
b. Findings
No findings of significance were identified.
1R18 Plant Modifications
.1 Temporary Modification
a. Inspection Scope
The inspectors reviewed the following temporary modification:
- Change to LEFM software constants The inspectors compared the temporary configuration changes and associated 10 CFR 50.59 screening and evaluation information against the design basis, the UFSAR, and the TSs, as applicable, to verify that the modification did not affect the operability or availability of the affected system. The inspectors also compared the licensee's information to operating experience information to ensure that lessons learned from other utilities had been incorporated into the licensee's decision to implement the temporary modification. The inspectors, as applicable, performed field verifications to ensure that the modifications were installed as directed; the modifications operated as expected; modification testing adequately demonstrated continued system operability, availability, and reliability; and that operation of the modifications did not impact the operability of any interfacing systems. Lastly, the inspectors discussed the temporary modification with operations, engineering, and training personnel to ensure that the individuals were aware of how extended operation with the temporary modification in place could impact overall plant performance. Documents reviewed are listed in the attachment. This inspection constitutes one sample as defined in Inspection Procedure 71111.18-05.

- Reactor vessel pressure high (RHR Isolation) Switch 1B21N679D, retest after replacement of failed card
- Division 1 diesel generator postmaintenance operability run after a repair of an oil leak on the right bank number five cylinder These activities were selected based upon the structure, system, or component's ability to impact risk. The inspectors evaluated these activities for the following (as applicable): the effect of testing on the plant had been adequately addressed; testing was adequate for the maintenance performed; acceptance criteria were clear and demonstrated operational readiness; test instrumentation was appropriate; tests were performed as written in accordance with properly reviewed and approved procedures; equipment was returned to its operational status following testing (temporary modifications or jumpers required for test performance were properly removed after test completion), and test documentation was properly evaluated. The inspectors evaluated the activities against TS, the UFSAR, 10 CFR Part 50 requirements, licensee procedures, and various NRC generic communications to ensure that the test results adequately ensured that the equipment met the licensing basis and design requirements. In addition, the inspectors reviewed corrective action documents associated with postmaintenance tests to determine whether the licensee was identifying problems and entering them in the CAP and that the problems were being corrected commensurate with their importance to safety. Documents reviewed are listed in the attachment. This inspection constitutes five samples as defined in Inspection Procedure 71111.19.
b. Findings

Cornerstones: Initiating Events, Mitigating Systems, Barrier Integrity, Emergency Preparedness, Public Radiation Safety, Occupational Radiation Safety, and Physical Protection
.1 Selected Issue Followup Inspection:
Probable Maximum Precipitation (PMP) Door Seals
a. Inspection Scope
The inspectors reviewed condition reports documenting probable maximum precipitation (PMP) door seals for
- (1) complete and accurate identification of the problem in a timely manner;
- (2) consideration of extent of condition;
- (3) classification and prioritization of the resolution of the problem;
- (4) identification of root and contributing causes of the problem;
- (5) identification of corrective actions; and
- (6) completion of corrective actions in a timely manner. The inspectors then performed a walk down of doors in the Train B standby service pump house and determined that the seals for those doors appeared to be degraded. The inspectors brought this to the attention of plant personnel. The plant performed an inspection of these door seals and an extent of condition and determined that eight out of eleven PMP doors seals protecting safety related equipment did not meet procedural requirements. The above constitutes completion of one in-depth problem identification and resolution sample.
b. Findings
Introduction.
The inspectors identified a Green violation of 10 CFR Part 50 Appendix B, Criterion V, "Instructions, Procedures, and Drawings," involving the failure to perform an adequate inspection of PMP door seals protecting safety related equipment.
Description.
The licensee had previously received a noncited violation for inadequate inspections of PMP door seals in NRC Inspection Report 05000416/2008002. On July 9, 2008, the inspectors were performing a follow up inspection of the PMP door seals at Grand Gulf from issues previously identified by the NRC in February 2008. The inspectors found the entrance door to the standby service water Train B pump house not meeting the standards of the maintenance procedure because the door seals failed to make contact with the door. The inspectors notified plant personnel of their concerns and an inspection of the standby service water pump house door seal determined that the PMP seal was in a degraded condition. The extent of condition review found seven additional door seals degraded, including the doors to the diesel generator building and control building.
The plant had entered the previous NRC identified violation from February 2008 into the corrective action program and completed actions to address non-compliant PMP door seals by performing an inspection of all PMP door seals and replacing those seals determined to be degraded. The plant also initiated compensatory actions for the ENCLOSURE 2 degraded seals, staging sand bags in the area and requiring monitoring of the affected doors during heavy rainfall. The door seal on the standby service water Train B pump house identified by the inspectors on July 9, 2008, had not been identified by plant personnel during an extent of condition review on February 29, 2008. Based on the replacement of four degraded PMP seals, the plant canceled their compensatory actions on March 16, 2008. The licensee performed an apparent cause evaluation (ACE), which included an extent of condition of all PMP seals. They concluded that they needed to formally put in place a periodic replacement time frame for the seals which was determined to be every five years. Additionally, they revised the inspection procedure by adding a clarifying note to the maintenance procedure for inspection of PMP door seals. Plant personnel restored compliance on July 9, 2008, when they reestablished the previous discussed compensatory actions. The licensee performed another ACE and determined that the PMP seals needed to be inspected quarterly and replacement of the seals should be performed every three years. The plant performed an engineering evaluation showing the amount of water that might have entered the affected areas with the degraded door seals and presented this to the inspectors. The site determined that under conservative assumptions, if a PMP event occurred with the door seals in their degraded conditions, not enough water would have entered the affected areas to disable the ability of the mitigating systems to perform their safety function. The inspectors reviewed the analysis and decided that the plant's assumptions and conclusion were satisfactory.
Analysis.
The inspectors determined that the failure to properly inspect and repair door seals that protect safety-related equipment from a PMP event is a performance deficiency. The finding is more than minor since it affects the protection against external factors attribute of mitigating system cornerstone. The door seals also represent a degrading condition that if left uncorrected could affect the availability, reliability, and capability of mitigating systems required to respond to initiating events to prevent undesirable consequences. Using the Manual Chapter 0609, "Significance Determination Process," Phase 1 Worksheet, the inspectors used the seismic, flooding, and severe weather Table 4b and determined it would affect multi-trains of safety equipment. The inspectors consulted the regional senior reactor analyst, who performed a Phase 3 analysis using many bounding and conservative assumptions. The result was a delta-CDF of 3.3E-7/yr and a delta-LERF of 6.6E-8/yr. These results confirmed that the finding had very low safety significance (Green). The cause of this finding has a crosscutting aspect in the area of problem identification and resolution in that the licensee failed to take adequate corrective actions to ensure degraded PMP door seals were properly evaluated and repaired in a timely manner P.1(d).
Enforcement.
10 CFR Part 50, Appendix B, Criterion V, "Instructions, Procedures and Drawings," states, in part, that activities affecting quality shall be accomplished in accordance with prescribed procedures. Contrary to this requirement, from March 16 through July 9, 2008, the licensee failed to accomplish an activity affecting quality in accordance with prescribed procedures. Specifically, the licensee failed to perform an adequate inspection of PMP door seals protecting safety-related equipment as prescribed in Procedure 07-S-14-310, "Inspection of Mechanical Seals on Doors," Revision 5. This finding has been entered into the licensee's CAP as CR-GGN-2008-03216. Due to the licensee's failure to restore compliance from the previous NCV 05000416/2008002-01 within a reasonable time after the violation was identified, ENCLOSURE 2 this violation is being cited as a Notice of Violation consistent with Section VI.A of the Enforcement Policy: VIO 05000416/2008004-03, Failure to Perform an Adequate Inspection of PMP Door Seals Protecting Safety Related Equipment.
.2 Routine Review of items Entered Into the CAP
a. Inspection Scope
As part of the various baseline inspection procedures discussed in previous sections of this report, the inspectors routinely reviewed issues during baseline inspection activities and plant status reviews to verify that they were being entered into the licensee's CAP at an appropriate threshold, that adequate attention was being given to timely corrective actions, and that adverse trends were identified and addressed. Attributes reviewed included: the complete and accurate identification of the problem; that timeliness was commensurate with the safety significance; that evaluation and disposition of performance issues, generic implications, common causes, contributing factors, root causes, extent of condition reviews, and previous occurrences reviews were proper and adequate; and that the classification, prioritization, focus, and timeliness of corrective actions were commensurate with safety and sufficient to prevent recurrence of the issue. Minor issues entered into the licensee's CAP as a result of the inspectors' observations are included in the attached list of documents reviewed. These routine reviews for the identification and resolution of problems did not constitute any additional inspection samples. Instead, by procedure they were considered an integral part of the inspections performed during the quarter and documented in Section 1 of this report.
b. Findings
No findings of significance were identified.
.3 Daily CAP Reviews
a. Scope
In order to assist with the identification of repetitive equipment failures and specific human performance issues for follow-up, the inspectors performed a daily screening of items entered into the licensee's CAP. This review was accomplished through inspection of the station's daily condition report packages. These daily reviews were performed by procedure as part of the inspectors' daily plant status monitoring activities and, as such, did not constitute any separate inspection samples.

4OA3 Followup of Events and Notices of Enforcement Discretion
.1 Sulfuric Acid Storage Tank A Unisolable Leak
a. Inspection Scope
The inspectors reviewed the plant's response to an un-isolable leak from an acid storage tank. On August 11, 2008, the plant personnel identified a 2-3 gallon per minute sulfuric acid leak from the acid storage Tank A into the berm area around the tank. The inspectors attended meetings, reviewed recovery, safety, and contingency plans. Additionally, they evaluated the decision process involving emergency action levels. Plant personnel along with vendor assistance stopped the leak by pumping the acid from the leaking tank to two other storage tanks on site. The inspectors also observed the interactions with the vendor that assisted the in the recovery. Documents reviewed in this inspection are listed in the Attachment.

.2 Suspected Resin Intrusion
a. Inspection Scope
The inspectors reviewed the response by plant personnel to a suspected resin intrusion from the reactor water cleanup demineralizer system. On September 18, 2008, while the plant was coasting down in power prior to RF16, the control room operators identified that the expected coast down power trend flattened out, showing an effective positive power increase in the reactor. The operators had recently attempted to place the reactor water clean up (RWCU) filter/demineralizer in service, but then removed it from service after the post-strainer showed a high differential pressure. The operators ENCLOSURE 2 entered the off-normal event procedure for resin intrusion, suspecting that the power increase had been caused by a resin intrusion from the RWCU system while placing the filter in service. After further review, the reactor engineering staff concluded that the coast down power trend had been displaying the flattening characteristic for some time, hence would not be a result of placing the RWCU filter in service. The inspectors responded to the control room and reviewed the RWCU system pressure and flow trends, reactor power trends, plant chemistry trends, and the operators' execution of the off-normal event procedure. Documents reviewed in this inspection are listed in the Attachment. This inspection constitutes one sample as defined in Inspection Procedure 71153-05.
.3 (Closed) LER 05000416/2008-001-00 "Manual Reactor SCRAM Due to Loss of Main Electrical Output Transformer Cooling"
On January 12, 2008, at 1626 hours0.0188 days <br />0.452 hours <br />0.00269 weeks <br />6.18693e-4 months <br />, the plant operators initiated a manual reactor scram from 99 percent power due to loss of cooling to the main transformers. The cause of this event was the loss of cooling to the main transformers caused by loss of auxiliary power to the main transformer cooling system. Inspection of the complete circuit for main transformer auxiliary power showed that the Phase B power cables were burned in two at the transfer switch panel. The cause of the Phase B power cable failure was attributed to failure of an electrical compression connection on a lug connection. This particular cable and connection had been inservice since plant start-up. The root causes were determined to be use of a compression connection for high current applications versus the preferred crimp type connection and an inadequate preventive maintenance strategy to provide early detection. Corrective actions included an inspection of the power panel and replacement of all damaged cabling. Documents reviewed as part of this inspection are listed in the attachment. No findings of significance were identified. This LER is closed.
.4 (Closed) LER 05000416/2008-002-00 "Reactor SCRAM Due to Main Generator Trip Caused by Unit Differential Lockout"
On March 21,2008 at 1525 hours0.0177 days <br />0.424 hours <br />0.00252 weeks <br />5.802625e-4 months <br />, the plant experienced an actuation of the Reactor Protection System (RPS) which resulted in an automatic scram from 100 percent power. The scram was due to main turbine control valve fast closure. The cause of the event was a main generator trip as the result of a Phase C unit differential lockout. Troubleshooting which included inspection of the high voltage circuit and check of calibration of both Relays A and B was initiated; however, no definitive cause for the trip was identified. As a result of trouble shooting the licensee took the following corrective actions. The low voltage CT circuit wiring and terminations were inspected to the extent possible. The main generator neutral bushing Phase C in the circuit had a replacement CT wired into the circuit. As a precaution, the suspect Phase C unit differential relay was replaced. No evidence of an actual fault condition was found and no evidence of animal intrusion in the high voltage bus work was found. Additionally, the calibration of Relays A and B was checked and found to be acceptable. Documents reviewed as part of this inspection are listed in the attachment. No findings of significance were identified. This LER is closed.

.5 (Closed) LER 05000416/2008-003-00 "Increased Bus Voltage Results in Breaker Trip on Over Current of a High Pressure Core Spray Pump Low Flow Valve Resulting in a Non-Compliance with Technical Specification 3.6.1.3, Primary Containment Isolation Valve Function" On March 05, 2008 at 1619, with the plant at about 99 percent reactor power, emergency core cooling system (ECCS) surveillance testing was being performed of the high pressure core spray (HPCS) pump and system.
The HPCS low flow Valve 1E22-F012 (also a primary containment isolation valve), while stroking from closed to open position, de-energized and the HPCS loss or overload status light energized. The valve was found in the non-closed position and the power supply breaker for the motor actuator for the valve was found tripped open. This condition was considered a violation of TS 3.6.1.3, "Primary Containment Isolation Valve," due to exceeding the limiting condition of operation (LCO) required action completion time of four hours to isolate the penetration. The cause of Valve 1E22-F012 failure to close was due to its supply breaker instantaneous over current trip settings being set too low, thus rendering the valve inoperable. The investigation revealed that this condition had existed since the early 1990s when bus voltages had been increased to a higher value to account for under voltage events. Corrective actions were implemented which included replacement of the Valve 1E22-F012 power supply breaker and increasing the instantaneous over current trip settings. Breaker settings for the other ECCS motor operator valves that were susceptible to this condition were checked and found to be acceptable. Documents reviewed as part of this inspection are listed in the attachment. The enforcement aspects of this finding were discussed in NRC Inspection Report 05000416/2008002 in Section 4OA3. This LER is closed.
4OA5 Other Activities
.1 Quarterly Resident Inspector Observations of Security Personnel and Activities
a. Inspection Scope
During the inspection period the inspectors conducted observations of security force personnel and activities to ensure that the activities were consistent with licensee security procedures and regulatory requirements relating to nuclear plant security. These observations took place during both normal and off-normal plant working hours. These quarterly resident inspector observations of security force personnel and activities did not constitute any additional inspection samples. Rather, they were considered an integral part of the inspectors' normal plant status reviews and inspection activities.
b. Findings
No findings of significance were identified.

4OA6 Management Meetings
.1 Exit Meeting Summary
On August 20, 2008, the branch chief conducted a regulatory performance meeting with Mr. M. Krupa, Director Nuclear Safety Assurance, and other members of the licensee staff to review corrective actions taken related to the White performance indicator for unplanned scrams per 7000 critical hours in the first quarter of 2008.
On August 22, 2008, the emergency preparedness inspector presented the results of the inspection of the onsite emergency preparedness program to Mr. R. Douet, Vice President, Operations, and other members of his staff, who acknowledged the findings. The inspectors confirmed that proprietary, sensitive, or personal information examined during the inspection had been returned to the identified licensee custodian. On September 29, 2008, the inspectors presented the inspection results to Mr. R. Douet and other members of the licensee staff. The licensee acknowledged the issues presented. The inspectors asked the licensee whether any materials examined during the inspection should be considered proprietary. No proprietary information was identified.
