Preparedness

1R01 Adverse Weather Protection

Readiness for Impending Adverse Weather Conditions

a. Inspection Scope

Since topical storms Bonnie and Danielle were forecasted in the vicinity of the facility on July 24, 2010 and August 12, 2010, respectively, the inspectors reviewed the licensees overall preparations and protection for the expected weather conditions. On July 24, 2010 and August 12, 2010, the inspectors walked down the emergency diesel generators and portions of the dry cooling towers because their safety-related functions could be affected, or required, as a result of high winds or tornado-generated missiles or the loss of offsite power. The inspectors evaluated the plant staffs preparations against the sites procedures to determine if the staffs actions were adequate. During the inspection, the inspectors focused on plant-specific design features and the licensees 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 verified operator staffing and accessibility of controls and indications for those systems required to control the plant. Additionally, the inspectors reviewed the updated final safety analysis report and performance requirements for the 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 licensee-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.

These activities constitute completion of two

(2) readiness for impending adverse weather condition samples as defined in Inspection Procedure 71111.01-05.

b. Findings

No findings were identified.

1R04 Equipment Alignments

.1 Partial Walkdown

a. Inspection Scope

The inspectors performed partial system walkdowns of the following risk-significant systems:

• On July 23, 2010, Train B of the low pressure safety injection system after testing the B LPSI pump

• On August 31, 2010, Train A of the chemical volume control system following in-service valve testing of one the control valves in the system

• On September 14, 2010, Train A of the low pressure safety injection system following an extended system outage

• On September 28, 2010, Train AB of the emergency feedwater system following an extended system outage

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 affect the function of the system, and, therefore, potentially increase risk. The inspectors reviewed applicable operating procedures, system diagrams, Updated Final Safety Analysis Report, technical specification requirements, administrative technical specifications, 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 inspected 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. Specific documents reviewed during this inspection are listed in the attachment.

These activities constitute completion of four

(4) partial system walkdown samples as defined in Inspection Procedure 71111.04-05.

b. Findings

No findings were identified.

.2 Complete Walkdown

a. Inspection Scope

On August 26, 2010, the inspectors performed a complete system alignment inspection of Train B of the control room ventilation system while Train A was inoperable for preventative maintenance activities to verify the functional capability of the system. The inspectors selected this system because it was considered both safety significant and risk significant in the licensees probabilistic risk assessment. The inspectors inspected 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. The inspectors reviewed a sample of past and outstanding work orders to determine whether any deficiencies significantly affected the system function. In addition, the inspectors reviewed the corrective action program database to ensure that system equipment-alignment problems were being identified and appropriately resolved. Specific documents reviewed during this inspection are listed in the attachment.

4OA2 Identification and Resolution of Problems

.1 Routine Review of Identification and Resolution of Problems

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 licensees corrective action program at an appropriate threshold, that adequate attention was being

given to timely corrective actions, and that adverse trends were identified and addressed. The inspectors reviewed attributes that included the complete and accurate identification of the problem; the timely correction, commensurate with the safety significance; the evaluation and disposition of performance issues, generic implications, common causes, contributing factors, root causes, extent of condition reviews, and previous occurrences reviews; and the classification, prioritization, focus, and timeliness of corrective actions. Minor issues entered into the licensees corrective action program because 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 were identified.

4OA3 Event Follow-up

.1 (Closed) Licensee Event Report (LER) 05000382/2008002-00, Inoperable Steam

Generator Narrow Range Level Channels On May 23, 2008, the licensee identified that one transmitter for Steam Generator No. 1 and one transmitter for Steam Generator No. 2 were inoperable during a previous cycle of operation and the associated technical specification of limiting condition for operation had not been entered. The licensee determined that the condition occurred due to an

inadequate procedure because the procedure did not provide sufficient detail to assure that proper manipulations of valves and venting of the sensing lines occurred after installation of the steam generator narrow range transmitters. These transmitters are used for trip input into the plant protective system for the steam generator narrow range level. Upon discovery of this condition, both steam generators transmitters were calibrated during the following refueling cycle, thus restoring the steam generator narrow range channels back to an operable status. This licensee-identified finding involved a violation of technical specification Table 3.3-1. The enforcement aspects of the violation are discussed in Section 4OA7. This licensee event report is closed is closed.

.2 (Closed) Licensee Event Report (LER) 05000382/2008004-00, Loose Intercell

Connecting Bolts on 125 Vdc Station Battery On September 3, 2008, the licensee declared the B train 125 Vdc station battery inoperable due to a low voltage condition. Upon further investigation, the licensee identified a loose battery connection of two intercell connecting bolts for battery cells 57 and 58. Operators immediately tightened the bolts and verified the inter-cell resistance.

The licensee concluded that the most likely cause of the loose connection was that the bolts were left loose during the replacement of the battery cell 56, performed on May 24, 2008. The licensee determined that the cause of the condition was a failure to maintain plant equipment status control due to a lack of specific work instructions and a lack of work order documentation of the intercell connectors that were loosened or removed during the May 24, 2008 maintenance activity. This issue and its associated notice of violation were discussed in NRC Inspection Report 05000382/2009008 and Supplemental Inspection Report 05000382/2010007. The licensee documented this issue in Condition Report CR-WF3-2008-04179. This licensee event report is closed.

.3 (Closed) Licensee Event Report (LER) 05000382/2008004-01, Loose Intercell

Connecting Bolts on 125 Vdc Station Battery This licensee event report is the revised report for the above mention loose battery connection of two intercell connecting bolts for battery cells 57 and 58. This issue and its associated notice of violation were discussed in NRC Inspection Report 05000382/2009008 and Supplemental Inspection Report 05000382/2010007. The licensee documented this issue in Condition Report CR-WF3-2008-04179. This licensee event report is closed.

4OA7 Licensee-Identified Violations

The following violation of very low safety significance (Green) was identified by the licensee and is a violation of NRC requirements which meet the criteria of the NRC Enforcement Policy, for being dispositioned as a non-cited violation.

On May 23, 2008, the licensee identified that one transmitter for Steam Generator No. 1 and one transmitter for Steam Generator No. 2 were inoperable during a previous cycle of operation with the associated technical specification of limiting condition for operation had not been entered. Specifically, the licensee operable with one less than the total number of channels required for startup or power operations without placing the channel in bypass or a trip condition within one hour. This was a violation of Technical Specification Table 3.3-1. The licensee determined that the cause was an inadequate procedure that did not provide enough detail to assure proper valve manipulation and venting to properly calibrate the transmitters. The licensee documented this issue in Condition Report CR-WF3-2008-02107. The corrective actions included enhancing training for temporary outage workers on how to properly calibrate the equipment, revising calibration procedures to provide specifics on appropriate set-up of sensing lines and to identify other reference leg level transmitter calibration procedures which are inadequate. This finding is more than minor because it is associated with the procedure quality attribute of the Mitigating System Cornerstone and affects the cornerstone objective to ensure the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences (i.e., core damage). This finding was considered to have very low safety significance (Green) after using NRC Manual Chapter 0609, Phase 1 screening worksheet under the Mitigation Systems Cornerstone.

This licensee-identified finding involved a violation of Technical Specification 3.3.1, Reactor Protective Instrumentation.
