SUMMARY OF FINDINGS

Inspection Report (IR) 05000315/2013002

, 05000316/2013002; 01/01/2013

- 3/31/2013; D. C. Cook Nuclear Power Plant, Units 1 & 2; Identification and Resolution of Problems; Other Activities This report covers a 3-month period of inspection by resident inspectors and announced baseline inspections by regional inspectors. Two Green findings were identified. One finding was considered a non-cited violation (NCV)of NRC regulations. The significance of inspection findings are indicated by their color (i.e., greater than Green, or Green, White, Yellow, Red) and determined using Inspection Manual Chapter (IMC) 0609, "Significance Determination Process" dated June 2, 2011. Cross-cutting aspect are determined using IMC 0310, "Components Within the Cross Cutting Areas" dated October 28, 2011.

All violations of NRC requirements are dispositioned in accordance with the NRC's Enforcement Policy dated June 7, 2012.

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. N RC-Identified and Self-Revealed Findings

Cornerstone: Initiating Events

Green: One self-revealing finding of very low safety significance (Green) with an associated NCV of Technical Specification (TS) 5.4.1 occurred because of a failure to implement plant procedure O HI-4000, Conduct of Operations (COOP). While responding to oscillating levels in steam generator (SG) #4 following a signal position controller failure and resultant power transient, control room operators failed to follow conduct of operations procedure requirements for establishing a control band for controllers placed in manual. This failure contributed to SG level s becoming unstable and rising to within 1 percent of the level for an automatic turbine trip and resultant reactor trip

. The licensee stabilized the plant and restored controller s to automatic.

Corrective actions included a debrief of personnel in the control room and a lessons learned to all operations personnel. The licensee entered the issue into the corrective action program.

The inspectors determined that the failure to implement the COOP procedure during at power operation was a licensee performance deficiency that warranted an evaluation in accordance with the Significance Determination Process (SDP). The inspectors concluded that performance deficiency was more than minor because it was associated with the Initiating Event cornerstone attribute of human performance and adversely impacted the cornerstone objective of limiting the likelihood of events that upset plant stability. Since the performance deficiency did not result in a reactor trip, the inspectors concluded that the finding was of very low safety significance. The finding includes the H.4(c) cross-cutting aspect in the work practices component of the human performance area because supervisory personnel in the control room did not provide effective oversight to support nuclear safety. Specifically, supervisory command and control was not effective while responding to a SG level transient that approached the turbine trip setpoint. (Section 4OA2)

Cornerstone: Mitigating

Systems

Green.

The inspectors identified a finding of very low safety significance for the failure to follow operability evaluation procedural guidance. Specifically, an evaluation was conducted for past-operability of the residual heat removal and containment spray systems due to the discovery of a void in the containment recirculation sump suction piping. However, the evaluation relied on computer software that has not been benchmarked to demonstrate its applicability to the type of analyses being conducted. This finding was entered into the licensee's Corrective Action Program (CAP) to revise the affected evaluation of past-operability

. Reanalysis using other appropriate methods determined th e piping was operable.

The performance deficiency was more than minor because it was associated with the Mitigating System Cornerstone attribute of equipment performance and adversely affected the cornerstone objective of ensuring the capability of systems that respond to initiating events to prevent undesirable consequences. In addition, the performance deficiency was more than minor because it was associated with the Barrier Integrit y cornerstone attribute of structure, system, component , and barrier performance and adversely affected the cornerstone objective of providing reasonable assurance that physical design barriers protect the public from radionuclide releases caused by accidents or events. The finding screened as of very low safety significance (Green) because it was a design deficiency confirmed not to result in loss of operability.

Specifically, the licensee performed an alternate operability determination which reasonably concluded the residual heat removal system was operable.

In addition, it did not represent an actual open pathway in the physical integrity of reactor containment or involve an actual reduction in function of hydrogen igniters in the reactor containment.

This finding did not involve enforcement action because no violation of regulatory requirements was identified.

The inspectors did not identify a cross-cutting aspect associated with this finding because it was not confirmed to reflect current performance. (Section 4OA5.1.b)

B. Licensee-Identified Violations

One violation of very low safety significance was identified by the licensee, and has been reviewed by inspectors. Corrective actions planned or taken by the licensee have been entered into the licensee's corrective action program. This violation and corrective action tracking numbers are listed in Section 4OA7 of this report.

Cornerstones: Initiating Events, Mitigating Systems, and Barrier Integrity 1R01 Adverse Weather Protection (71111.01)

.1 Readiness for Impending Adverse Weather Condition

-Snowfall mixed with freezing rain and sleet conditions

a. Inspection Scope

On Thursday, February 7, 2013, a winter weather advisory was issued for expected snow, freezing rain and sleet conditions

. The inspectors observed the licensee's preparations and planning for the significant winter weather potential. The inspectors reviewed licensee procedures and discussed potential compensatory measures with control room personnel. The inspectors focused on plant management's actions for implementing the station's procedures for ensuring adequate personnel for safe plant operation and emergency response would be available. The inspectors conducted a site walkdown of various plant structures and systems to check for maintenance or other apparent deficiencies that could affect system operations during the predicted significant weather. The inspectors also reviewed Corrective Action Program (CAP) items to verify that the licensee was identifying adverse weather issues at an appropriate threshold and entering them into their CAP in accordance with station corrective action procedures.

Specific documents reviewed during this inspection are listed in the Attachment to this report. This inspection constituted o ne readiness for impending adverse weather condition sample as defined in Inspection Procedure (IP)

71111.01 - 05.

1R04 Equipment Alignment

(71111.04)

.1 Quarterly Partial System Walkdowns

a. Inspection Scope

The inspectors performed partial system walkdowns of the following risk

-significant systems: Unit 1 AB emergency diesel generator (EDG) system with Unit 1 CD EDG out of service; Unit 1 south control room air conditioning (CRAC) system with Unit 1 north CRAC system out of service; and Unit 2 south CRAC system with Unit 2 north CRAC system out of service.

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, Updated Final Safety Analysis Report (UFSAR), Technical Specifications (TS) requirements, outstanding work orders (WOs), condition reports, and the impact of ongoing work activities on redundant trains of equipment in order to identify conditions that could have rendered the systems incapable of performing their intended functions. The inspectors also walked down accessible portions of the systems to verify system components and support equipment were aligned correctly and operable. The inspectors examined the material condition of the components and observed operating parameters of equipment to verify 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 CAP with the appropriate significance characterization. Documents reviewed are listed in the Attachment to this report. These activities constituted three partial system walkdown sample s as defined in IP

71111.04 - 05.

b. Findings

No findings were identified.

.2 Semi-Annual Complete System Walkdown

a. Inspection Scope

During the week of February 25, 2013, the inspectors performed a complete system alignment inspection of the Unit 1 auxil iary feedwater (AFW) 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 lineups; 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 WOs was performed to determine whether any deficiencies significantly affected the system function.

In addition, the inspectors reviewed the CAP database to ensure that system equipment alignment problems were being identified and appropriately resolved. Documents reviewed are listed in the Attachment to this report

. These activities constituted one complete system walkdown sample as defined in IP

71111.04 - 05.

b. Findings

No findings were identified.

1R05 Fire Protection

(71111.05)

.1 Routine Resident Inspector Tours

. The inspectors reviewed areas to assess if the licensee had implemented a fire protection program that adequately controlled combustibles and ignition sources within the plant, effectively maintained fire detection and suppression capability, maintained passive fire protection features in good material condition, and implemented adequate compensatory measures for out-of-service, degraded or inoperable fire protection equipment, systems, or features in accordance with the 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. Usi ng the documents listed in the Attachment to this report, 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 CAP. Documents reviewed are listed in the Attachment to this report.

These activities constituted four quarterly fire protection inspection samples as defined in IP

71111.05 - 05.

b. Findings

No findings were identified.

.2 Annual Fire Protection Drill Observation

(71111.05A)

a. Inspection Scope

On March 6, 2013, the inspectors observed fire brigade activation for an unannounced fire drill that simulated an electrical fire in the turbine building. Based on this observation , the inspectors evaluated the readiness of the plant fire brigade to fight fires. The inspectors verified that the licensee staff identified deficiencies; openly discussed them in a self-critical manner at the drill debrief

and took appropriate corrective actions. Specific attributes evaluated were

proper wearing of turnout gear and self

-contained breathing apparatus; proper use and layout of fire hoses; employment of appropriate fire fighting techniques; sufficient firefighting equipment brought to the scene; effectiveness of fire brigade leader communications, command and control; search for victims and propagation of the fire into other plant areas; smoke removal operations; utilization of pre-planned strategies; adherence to the pre-planned drill scenario; and drill objectives.

The inspectors reviewed the plant Final Safety Analysis Report to identify areas of the plant designed as potential airborne radiation areas and any associated ventilation systems or airborne monitoring instrumentation. Instrumentation review included continuous air monitors (continuous air monitors and particulate

-iodine-noble-gas-type instruments) used to identify changing airborne radiological conditions such that actions to prevent an overexposure may be taken. The review included an overview of the Respiratory Protection Program and a description of the types of devices used. The inspectors reviewed Final Safety Analysis Report, TSs, and emergency planning documents to identify location and quantity of respiratory protection devices stored for emergency use.

Inspectors reviewed the licensee's procedures for maintenance, inspection, and use of respiratory protection equipment including self

-contained breathing apparatus, as well as procedures for air quality maintenance.

The inspectors reviewed reported performance indicators to identify any related to unintended dose resulting from intakes of radioactive material.

c. Findings

No findings were identified.

.2 Engineering Controls

(02.0 2)

b. Inspection Scope

The inspectors reviewed the licensee's use of permanent and temporary ventilation to determine whether the licensee uses ventilation systems as part of its engineering controls (in lieu of respiratory protection devices) to control airborne radioactivity.

The inspectors reviewed procedural guidance for use of installed plant systems, such as containment purge, spent fuel pool ventilation, and auxiliary building ventilation, and assessed whether the systems are used, to the extent practicable, during high

-risk activities (e.g., using containment purge during cavity floodup).

The inspectors selected installed ventilation systems used to mitigate the potential for airborne radioactivity, and evaluated whether the ventilation airflow capacity, flow path (including the alignment of the suction and discharges), and filter/charcoal unit efficiencies, as appropriate, were consistent with maintaining concentrations of airborne radioactivity in work areas below the concentrations of an airborne area to the extent practicable. The inspectors selected temporary ventilation system setups (high

-efficiency particulate air/charcoal negative pressure units, down draft tables, tents, metal "Kelly buildings," and other enclosures) used to support work in contaminated areas. The inspectors assessed whether the use of these systems is consistent with licensee procedural guidance and as

-low-as-is-reasonably

-achievable concept.

The inspectors reviewed airborne monitoring protocols by selecting installed systems used to monitor and warn of changing airborne concentrations in the plant and evaluated whether the alarms and setpoints were sufficient to prompt licensee/worker action to ensure that doses are maintained within the limits of 10 CFR Part 20 and the as-low-as-is-reasonably

-achievable concept.

The inspectors assessed whether the licensee had established trigger points (e.g., the Electric Power Research Institute's "Alpha Monitoring Guidelines for Operating Nuclear Power Stations") for evaluating levels of airborne beta

-emitting (e.g., plutonium

-241) and alpha-emitting radionuclides.

c. Findings

No findings were identified.

.3 Use of Respiratory Protection Devices

(02.0 3)

b. Inspection Scope

For those situations where it is impractical to employ engineering controls to minimize airborne radioactivity, the inspectors assessed whether the licensee provided respiratory protective devices such that occupational doses are as

-low-as-is-reasonably

-achievable. The inspectors selected work activities where respiratory protection devices were used to limit the intake of radioactive materials, and assessed whether the licensee performed an evaluation concluding that further engineering controls were not practical and that the use of respirators is as

-low-as-is-reasonably

-achievable. The inspectors also evaluated whether the licensee had established means (such as routine bioassay) to determine if the level of protection (protection factor) provided by the respiratory protection devices during use was at least as good as that assumed in the licensee's work controls and dose assessment.

The inspectors assessed whether respiratory protection devices used to limit the intake of radioactive materials were certified by the National Institute for Occupational Safety and Health/Mine Safety and Health Administration or have been approved by the NRC per 10 CFR 20.1703(b). The inspectors selected work activities where respiratory protection devices were used. The inspectors evaluated whether the devices were used consistent with their National Institute for Occupational Safety and Health/Mine Safety and Health Administration certification or any conditions of their NRC approval.

The inspectors reviewed records of air testing for supplied

-air devices and self-contained breathing apparatus bottles to assess whether the air used in these devices meets or exceeds Grade D quality. The inspectors reviewed plant breathing air supply systems to determine whether they meet the minimum pressure and airflow requirements for the devices in use.

The inspectors selected several individuals qualified to use respiratory protection devices, and assessed whether they have been deemed fit to use the devices by a physician.

The inspectors selected several individuals assigned to wear a respiratory protection device and observed them donning, doffing, and functionally checking the device as appropriate. Through interviews with these individuals, the inspectors evaluated whether they knew how to safely use the device and how to properly respond to any

device malfunction or unusual occurrence (loss of power, loss of air, etc.).

The inspectors chose multiple respiratory protection devices staged and ready for use in the plant or stocked for issuance for use. The inspectors assessed the physical condition of the device components (mask or hood, harnesses, air lines, regulators, air bottles, etc.) and reviewed records of routine inspection for each. The inspectors selected several of the devices and reviewed records of maintenance on the vital components (e.g., pressure regulators, inhalation/exhalation valves, hose couplings

). The inspectors reviewed the respirator vital components maintenance program to ensure onsite personnel assigned to repair the vital components have received the appropriate manufacturer-approved training.

c. Findings

No findings were identified.

.4 Self-Contained Breathing Apparatus for Emergency Use

(02.04)

b. Inspection Scope

Based on the Final Safety Analysis Report, TSs, and emergency operating procedure requirements, the inspectors reviewed the status and surveillance records of self-contained breathing apparatuses staged in

-plant for use during emergencies. The inspectors reviewed the licensee's capability for refilling and transporting self-contained breathing apparatus air bottles to and from the control room and operations support center during emergency conditions.

The inspectors selected several individuals on control room shift crews and from designated departments currently assigned emergency duties (e.g., onsite search and rescue duties) to assess whether control room operators and other emergency response and radiation protection personnel (assigned in

-plant search and rescue duties or as required by emergency operating procedures or the emergency plan) were trained and qualified in the use of self

-contained breathing apparatuses (including personal bottle changeout). The inspectors evaluated whether personnel assigned to refill bottles were trained and qualified for that task.

The inspectors determined whether appropriate mask sizes and types are available for use (i.e., in

-field mask size and type match what was used in fit

-testing). The inspectors determined whether on-shift operators had any facial hair that would interfere with the sealing of the mask to the face and whether vision correction (e.g., glasses inserts or corrected lenses) was available as appropriate.

The inspectors reviewed the past 2 years of maintenance records for select self-contained breathing apparatus units used to support operator activities during accident conditions and designated as "ready for service" to assess whether any maintenance or repairs on any self-contained breathing apparatus unit's vital components were performed by an individual, or individuals, certified by the manufacturer of the device to perform the work. The vital components typically are the pressure-demand air regulator and the low

-pressure alarm. The inspectors reviewed the onsite maintenance procedures governing vital component work to determine any inconsistencies with the self-contained breathing apparatus manufacturer's recommended practices. For those self-contained breathing apparatuses designated as "ready for service," the inspectors determined whether the required, periodic air cylinder hydrostatic testing was documented and up to date, and the retest air cylinder markings required by the U.S. Department of Transportation were in place.

c. Findings

No findings were identified.

.5 Problem Identification and Resolution

(02.05)

b. Inspection Scope

71124.04 - 0 5.

.1 Inspection Planning (02.01)

a. Inspection Scope

The inspectors reviewed the results of Radiation Protection Program audits related to internal and external dosimetry, (e.g., licensee's quality assurance audits, self-assessments, or other independent audits) to gain insights into overall licensee performance in the area of dose assessment and focus the inspection activities consistent with the principle of "smart sampling."

The inspectors reviewed the most recent National Voluntary Laboratory Accreditation Program accreditation report on the vendor's most recent results to determine the status of the contractor's accreditation.

A review was conducted of the licensee procedures associated with dosimetry operations, including issuance/use of external dosimetry (routine, multibadging, extremity, neutron, etc.), assessment of internal dose (operation of whole body counter, assignment of dose based on derived air concentration

-hours, urinalysis, etc.), and evaluation of and dose assessment for radiological incidents (distributed contamination, hot particles, loss of dosimetry, etc.).

The inspectors evaluated whether the licensee had established procedural requirements for determining when external and internal dosimetry is required.

b. Findings

No findings were identified.

.2 External Dosimetry

(02.02)

a. Inspection Scope

The inspectors evaluated whether the licensee's dosimetry vendor is National Voluntary Laboratory Accreditation Program accredited and if the approved irradiation test categories for each type of personnel dosimeter used are consistent with the types and energies of the radiation present and the way the dosimeter is being used, (e.g., to measure deep dose equivalent, shallow dose equivalent, or lens dose equivalent).

The inspectors evaluated the onsite storage of dosimeters before their issuance, during use, and before processing/reading. The inspectors also reviewed the guidance provided to rad

-workers with respect to care and storage of dosimeters.

The inspectors assessed the use of active dosimeters (electronic personal dosimeters) to determine if the licensee uses a "correction factor" to address the response of the electronic personal dosimeter as compared to the passive dosimeter for situations when the electronic personal dosimeter must be used to assign dose. The inspectors also assessed whether the correction factor is based on sound technical principles.

The inspectors reviewed dosimetry occurrence reports or CAP documents for adverse trends related to electronic personal dosimeters, such as interference from electromagnetic frequency, dropping or bumping, failure to hear alarms, etc. The inspectors assessed whether the licensee had identified any trends and implemented appropriate corrective actions.

b. Findings

No findings were identified.

.3 Internal Dosimetry

(02.03) Routine Bioassay (In Vivo)

a. Inspection Scope

The inspectors reviewed procedures used to assess the dose from internally deposited nuclides using whole body counting equipment. The inspectors evaluated whether the procedures addressed methods for differentiating between internal and external contamination, the release of contaminated individuals, the route of intake and the assignment of dose.

The inspectors reviewed the whole body count process to determine if the frequency of measurements was consistent with the biological half

-life of the nuclides available for intake.

The inspectors reviewed the licensee's evaluation for use of its portal radiation monitors as a passive monitoring system to determine if instrument minimum detectable activities were adequate to determine the potential for internally deposited radionuclides sufficient to prompt additional investigation.

The inspectors selected several whole body counts and evaluated whether the counting system used had sufficient counting time/low background to ensure appropriate sensitivity for the potential radionuclides of interest. The inspectors reviewed the radionuclide library used for the count system to determine its appropriateness. The inspectors evaluated whether any anomalous count peaks/nuclides indicated in each output spectra received appropriate disposition. The inspector's reviewed the licensee's 10 CFR Part 61 data analyses to determine whether the nuclide libraries included appropriate gamma

-emitting nuclides. The inspectors evaluated how the licensee accounts for hard

-to-detect nuclides in the dose assessment.

b. Findings

No findings were identified.

Special Bioassay (In Vitro)

a. Inspection Scope

There were no internal dose assessments obtained using in vitro monitoring for the inspectors to review.

.4 Special Dosimetric Situations

(02.04) Declared Pregnant Workers

a. Inspection Scope

The inspectors assessed whether the licensee informs workers, as appropriate, of the risks of radiation exposure to the embryo/fetus, the regulatory aspects of declaring a pregnancy, and the specific process to be used for (voluntarily) declaring a pregnancy.

The inspectors selected individuals who had declared pregnancy during the current assessment period and evaluated whether the licensee's radiological monitoring program (internal and external) for declared pregnant workers is technically adequate to assess the dose to the embryo/fetus. The inspectors reviewed exposure results and monitoring controls employed by the licensee and with respect to the requirements of 10 CFR Part 20.

b. Findings

No findings were identified.

Dosimeter Placement and Assessment of Effective Dose Equivalent for External Exposures

a. Inspection Scope

The inspectors reviewed the licensee's methodology for monitoring external dose in non-uniform radiation fields or where large dose gradients exist. The inspectors evaluated the licensee's criteria for determining when alternate monitoring, such as use of multi-badging, was to be implemented.

The inspectors reviewed dose assessments performed using multibadging to evaluate whether the assessment was performed consistently with licensee procedures and dosimetric standards.

b. Findings

No findings were identified.

Shallow Dose Equivalent

a. Inspection Scope

b. Finding s No findings were identified.

Neutron Dose Assessment

a. Inspection Scope

The inspectors evaluated the licensee's neutron dosimetry program, including dosimeter types and/or survey instrumentation.

The inspectors reviewed neutron exposure situations (e.g., independent spent fuel storage installation operations or at

-power containment entries) and assessed whether

(a) dosimetry and/or instrumentation was appropriate for the expected neutron spectra,

(b) there was sufficient sensitivity for low dose and/or dose rate measurement, and

(c) neutron dosimetry was properly calibrated. The inspectors also assessed whether interference by gamma radiation had been accounted for in the calibration and whether time and motion evaluations were representative of actual neutron exposure events, as applicable.

b. Findings

No findings were identified.

Assigning Dose of Record

a. Inspection Scope

For the special dosimetric situations reviewed in this section, the inspectors assessed how the licensee assigns dose of record for total effective dose equivalent, shallow dose equivalent, and lens dose equivalent.

(71152) Cornerstones: Initiating Events, Mitigating Systems, Barrier Integrity, Emergency Preparedness, Public Radiation Safety, Occupational Radiation Safety, and Physical Protection

.1 Routine Review of Items Entered into the Corrective Action Program

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 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: identification of the problem was complete and accurate; timeliness was commensurate with the safety significance; 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 Attachment to this report.

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.

.3 Selected Issue Follow

-Up: Steam Generator Level Transient

b. Inspection Scope

The inspectors reviewed the apparent cause evaluation associated with a secondary plant transient that occurred on November 30 , 2012. While raising power after repairing a leak on a steam generator (SG) level instrument, a steam control valve failed causing a rapid 5 percent power increase. The operations crew took appropriate immediate actions and stabilized the plant a t 28 percent power. The control room operators noted that the feedwater regulation valve (F RV) for th e #4 SG was oscillating and became concerned with FRV operation. In order to assess the FRV response, the licensee placed the FRV in manual. When this action did not produce the expected result, the licensee placed the main feed pump (MFP) speed controller in manual. Feedwater regulatin g valve response remained a concern. After about 20 minutes, the transient caused the secondary plant parameters to change, resulting in a decrease in SG level. While attempting to correct the low level, control room operators added too much water, too quickly, to the SG and level rose to within 1 percent of the high SG level turbine trip setpoint.

The inspectors assessed the apparent cause evaluation through comparison to the licensee's CAP. The inspectors assessed the operations crew by comparing the documented performance with applicable licensee procedures including OHI

-4000, COOP and 1-OHP-4021-001-006, Power Escalation. The inspectors also reviewed the controller failure that initiated the transient and noted that the component failed due to a manufacturing error. The controller had been installed for several years and the nature of the defect precluded detection prior to the failure. The inspectors concluded that the controller failure was not reasonably within the licensee's ability to foresee and correct.

This review constituted one in

-depth problem identification and resolution sample as defined in IP 7 1152-05.

c. Findings

Introduction

One self-revealing finding of very low safety significance (Green) with an associated NCV of TS 5.4.1 occurred because of a failure to implement plant procedures including COOP. While responding to oscillating levels in SG #4 following a signal position controller failure and resultant power transient, the control room operators failed to follow COOP procedure requirements for establishing a control band for controllers placed in manual. This failure contributed to SG level becoming unstable and rising to within 1 percent of the level for an automatic turbine trip and resultant reactor trip.

Description

On November 30, 2012, with Unit 2 power escalation in progress, the main turbine control valve "D" signal position controller failed causing a 5.3 percent reactor power increase and consequential steam generator oscillation in all four steam generators. After stabilizing the main turbine control valve and steam generator levels, the operations crew evaluated plant conditions and identified oscillations of the SG

1. 4 FRV control signal. Although SG level remained at program level of 44 percent, the on-shift crew had concerns due to the FRV position oscillations. In an attempt to stabilize the signal, the control room operators took the west MFP to manual speed control. Per COOP, when controllers are taken to manual, a control band shall be established; however, the control room operators failed to establish a control band for pump differential pressure.

When taking the controller to manual did not have the intended effect, control room operators placed SG #4 FRV in manual to dampen the oscillation. After placing the FRV in manual control, reactor operator (RO) #1 noted sluggish response from the controller. The shift crew began investigating the FRV response, including local observation by an auxiliary operator.

During this time, reactor coolant system temperature rose, as expected, which caused SG pressure to rise and resulted in differential pressure across the MFP dropping from 135 psid to 35 psid. The licensee did not recognize this trend for about 15 minutes. Once recognized, RO#2 was assigned to relieve RO#1 of FRV control responsibilities. Reactor Operator #1 began increasing MFP speed to restore feed pump differential. Shortly thereafter, SG #4 received a low level deviation alarm. Reactor Operator #1 raised the rate of MFP speed increase , which initiated a rapid increase in #4 SG level. Level in #4 SG increased to the high level deviation alarm and reached 66 percent level before RO#2 could stop the level increase. At 67 percent level on two of three level indications on any steam generator, the turbine will trip and then the reactor will trip

, as designed. The licensee subsequently place d the FRV in automatic and stabilized the plant.

During the approximately 20 minutes between placing the FRV in manual and reaching the highest level in the SG, the shift manager advised the unit supervisor (US) several times to restore the FRV to automatic.

The US left the FRV in manual during this period because of concerns with the FRV performance. The licensee's subsequent investigation revealed that the US and shift manager did not have a common understanding of each other's intentions.

Therefore, the US delayed ordering the FRV to be restored to automatic.

As part of the licensee's analysis, this scenario was replicated on the simulator. The licensee demonstrated in the simulator that had the operators restored the FRV to automatic or limited the speed increase on the MFP the SG level control issues would not have occurred.

The inspectors concluded that had control bands been established, the level transient would likely not occur.

Analysis:

The inspectors determined that failure to implement the COOP procedure during at power operation was a licensee performance deficiency that warranted an evaluation in accordance with the SDP. In this event, the control room operator's failure to establish control bands for MFP differential pressure was an issue of concern because it resulted in a SG level transient that came within 1 percent of an automatic turbine trip and a resultant reactor trip. The inspectors reviewed the issue of concern in accordance with Inspection Manual Chapter (IMC) 0612 Appendix B , Issue Screening, issued September 7, 2012. Since the issue of concern does not include any willful aspects, the inspectors evaluated the issue using only the reactor oversight process. The inspectors concluded that the issue of concern was a more than minor performance deficiency because it was associated with the Initiating Event cornerstone attribute of human performance and adversely impacted the cornerstone objective of limiting the likelihood of events that upset plant stability. Specifically, the human performance errors in executing plant procedures resulted in a SG level transient that came within 1 percent of a plant trip.

In accordance with IMC 0609, Appendix A , SDP for Findings at Power, Exhibit 1 , Intiating Events Screening Questions, issue d June 19, 2012

, the finding screened as Green because no reactor trip occurred.

The finding includes the cross-cutting aspect H.4 (c ) in the work practices component of the human performance area because supervisory personnel in the control room did not provide effective oversight to support nuclear safety. Specifically, supervisory command and control was not effective while responding to a SG level transient that approached the turbine trip set point.

Enforcement:

Technical Specification 5.4.1 requires, in part, that the licensee implement procedures recommended by Regulatory Guide 1.33. Regulatory Guide 1.33 recommends procedures for authorities and responsibilities for safe operation as well as procedures for operation of the feedwater system. The licensee satisfies these requirements, in part, through OHI

-4000, Conduct of Operations. OHI-4000 Attachment 8, Step 3.7

, requires that when a controller is placed in manual that the US shall provide a control band and that if a control band is not provided, the RO shall request a control band. Contrary to this requirement, on November 30, 2012, when the main feed pump controller was placed in manual, the US failed to provide a control band and RO#1 failed to request a control band. Consequently, a SG level transient occurred. Following the transient, the control room operators stabilized the plant and placed the controller in automatic. For corrective actions, the on

-shift control room operators were debriefed and lessons learned were provided to all operations personne l. Because the finding was of very low safety significance and the licensee entered the finding into their CAP as AR 2012-14938, this violation is being treated as an NCV, consistent with Section 2.3.2 of the enforcement policy (NCV 05000315/2013002

-01 , Failure to Establish Feed Pump Control Bands)

.

.4 Selected Issue Follow

-Up: Work Hour Limitation Waivers Not Filled Out Apparent Cause Evaluation

b. Inspection Scope

The inspectors selected the following apparent cause evaluation for an in

-depth review:

AR 2013-1149, "Work Hour Limitation Waivers Not Filled Out

" The inspectors discussed the evaluation and associated corrective actions with licensee personnel and verified the following attributes while reviewing the apparent cause evaluation:

complete and accurate problem identification in a timely manner commensurate with its safety significance and ease of discovery; extent of condition, generic implications, common cause and previous occurrences were considered; problem resolution was classified and prioritized commensurate with safety significance; apparent and contributing causes were identified; and appropriately focused corrective actions were identified.

The inspectors compared the information documented in the action request and its supporting documentation to the requirements of 10 CFR Part 26.

The inspectors determined that a minor violation of 10 CFR Part 26.207 (a), Waivers and exceptions , occurred. Specifically, the licensee failed to grant waivers based upon fatigue assessments before workers exceeded working hours limitations specified in 10 CFR Part 26.205. 10 CFR part 26.205 states in part, "Licensees shall ensure that any individual's work hours do not exceed 26 hours3.009259e-4 days <br />0.00722 hours <br />4.298942e-5 weeks <br />9.893e-6 months <br /> in any 48 period." In this instance, 5 maintenance workers exceeded the limit by 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> and one worker exceeded the limit by 30 minutes.

10 CFR Part 26.207 permit s the use of waiver requests to allow working hours to be exceeded to address circumstances that could not have been reasonably controlled. For waivers, 10 CFR part 26.207 (a

)(4) requires licensees to document the basis for individual waivers. Contrary to this requirement, the licensee failed to document the waivers and fatigue assessments prior to allowing the covered workers to exceed their working hour limitations. The inspectors noted that the licensee validated that the workers had been assessed for fatigue but lack of documentation precluded an assessment of the adequacy of the assessment. Licensee procedure PMP-2060-WHL-001, "Working Hour Limitations for Covered Individuals,"

Section 3.10.2a states, "the approval for a waiver from working hour limitations shall be obtained before the individual exceeds any working hour limits." The inspectors determined that failure to document the waivers and fatigue assessments prior to allowing the covered workers to exceed their working hour limitations was a performance deficiency.

The inspectors compared this performance deficiency to the examples listed in IMC 0612 Appendix E, issue date August 11, 2009, and determined example 9b, "failure to assess individual's competency to perform duties prior to granting work hour waivers" was similar to this issue. Specifically, the failure to document the fatigue assessment prior to exceeding working hour limitations was an isolated incident that did not become associated with a cornerstone attribute and did not adversely affect the cornerstone objective.

Consequently, this failure to comply with 10 CFR Part 26.207 constitutes a minor violation that is not subject to enforcement action in accordance with the NRC

(71153)

.1 (Closed) Licensee Event Report 05000316/2012

00 a. Inspection Scop e The inspectors reviewed the events and circumstances surrounding the April 30, 2012, Unit 2 automatic reactor trip that occurred in response to a main turbine trip. The inspectors reviewed control room logs , the post-trip review report and the root cause evaluation that was documented in AR 2012

-5744, "Unit 2 Overall Differential Relay Actuation ," to verify that the event was accurately reported.

On April 30, 2012, while at 92 percent power and ascending to 100 percent power, the Unit 2 generator volts

-per-hertz differential relay actuated causing a turbine trip and subsequent reactor trip. An investigation by licensee personnel concluded that the relay actuation did not result from an actual electrical fault but instead resulted from a failure to install the relay per design.

In addition to reviewing the automatic reactor trip response, the inspectors reviewed the temperature transient that occurred during cool down that resulted from steam dump valve leakage to the main condenser

, which required closing the main steam isolation valves and cooling down on the steam generator power operated relief valves.

The inspectors verified that the reactor trip was uncomplicated, all major components functioned as designed, and that operator actions were appropriate. This issue resulted in a finding of very low safety significance (Green), which was documented in inspection report 05000316/2012003. No other safety issues were identified. This Licensee Event Report (LER) is closed.

-09): Computer Program Used for Operability Evaluation Was Not Benchmarked

a. Inspection Scope

The NRC documented an unresolved item (URI) in Inspection Report 05000 315/2012008; 05000 316/2012008 (ML12229 A 576) involving the use of computer software Flow

-3D for the past

-operability evaluation of a void found in the containment recirculation sump suction piping. Specifically, the inspectors questioned if the use of this software was appropriate given that it was not benchmarked for this intended application. The issue was left unresolved pending the licensee's revised past-operability evaluation and determination of subsequent NRC courses of action. During this inspection period, the inspectors received information to resolve this issue. The documents that were reviewed are included in the Attachment to this report.

This review did not represent an inspection sample.

This Unresolved Item (URI) is closed.

b. Findings

Operability Evaluation Relied on Alternate Methods Not Demonstrated to be Technically Appropriate Introduction

The inspectors identified a finding of very low safety significance for the failure to follow operability evaluation procedural guidance. Specifically, an evaluation for past-operability of the residual heat removal and containment spray systems was conducted due to the discovery of a void in th e containment recirculation sump suction piping. However, the evaluation relied on computer software that has not been benchmarked to demonstrate its applicability to the type of analyses being conducted.

Description:

The licensee discovered a void in the containment recirculation sump suction piping in January 2009 affecting the 'B' train of residual heat removal and containment spray systems. The licensee captured this condition in the CAP as AR 00844125, removed the void and performed a past

-operability evaluation using computer software Flow

-3D Version 9.0. The inspectors noted procedure PMP-7030-OPR-001, "Operability Determination," referred to NRC Inspection Manual Part 9900 to assist in determining operability. NRC Regulatory Issue Summary 2005-20, Revision 1, "Revision to NRC Inspection Manual Part 9900 Technical Guidance, 'Operability Determinations and Functionality Assessments for Resolution of Degraded or Nonconforming Conditions Adverse to Quality or Safety,'" informed licensees that the NRC had revised NRC Inspection Manual Part 9900. Guidance provided in Appendix C, Section C.4 of the inspection manual stated

, "the use of any analytical method must be technically appropriate to characterize the SSCs involved, the nature of the degraded o r nonconforming condition, and specific facility design." It further stated general considerations for establishing this adequacy include, in part, acceptable alternative methods such as the use of "best estimate" codes, methods and techniques. The inspection guidance also stated "in these cases, the evaluation should ensure that the SSC's performance is not over

-predicted by performing a benchmark comparison of the non-current licensing basis (CLB) analysis methods to the applicable CLB analysis methods."

When the inspectors questioned if the computer code used in the operability determination was verified against test data, the licensee determined no benchmark flow modeling was conducted for two-phase flow in piping. The inspectors, in consultation with Nuclear Reactor Regulation, determined the operability evaluation relied on a computer code that had not been demonstrated to be technically appropriate for the type of analyses being conducted; therefore, the bases for past operability were uncertain.

The licensee captured the inspectors

' concerns in their CAP as AR 2012-8187. In addition, the licensee re

-performed the past

-operability evaluation using an analytical method which did not rely on computer software and reasonably concluded the affected systems had been operable.

The inspectors concluded that the licensee did not appropriately follow the guidance specified in the operability procedure. Following procedure guidance is a site standard.

Analysis:

The inspectors determined that the failure to perform an operability evaluation using a methodology that was technically appropriate was a performance deficiency. Specifically, not using a technically appropriate methodology was contrary to the guidance in NRC Inspection Manual Part 9900, which was referenced in plant procedure PMP-7030-OPR-001. The performance deficiency was more than minor because it was associated with the Mitigating System Cornerstone attribute of equipment performance and adversely affected the cornerstone objective of ensuring the capability of systems that respond to initiating events to prevent undesirable consequences. In addition, the performance deficiency was more than minor because it was associated with the Barrie r Integrity Cornerstone attribute of SSC and barrier performance and adversely affected the cornerstone objective of providing reasonable assurance that physical design barriers protect the public from radionuclide releases caused by accidents or events. Specifically, the inspectors had reasonable doubt on the past operability of the 'B' residual heat removal and containment spray systems because the licensee's evaluation relied on inputs and a methodology that were not technically appropriate for the intended applications.

Based on the size of the void and the complexities of void transport behavior at the affected location, it was not certain that a new or revised evaluation would result in the same operable conclusion.

A technically inappropriate operability evaluation could reasonably result in an unrecognized inoperable condition, which could lead to a failure to evaluate if the condition warranted notification to the NRC.

The inspectors determined the finding could be evaluated using the SDP in accordance with IMC 0609, "Significance Determination Process," Attachment 0609.04, "Initial Characterization of Findings

," issue date June 19, 2012.

Because the finding impacted the Mitigating Systems cornerstone, the inspectors screened the finding through IMC 0609 Appendix A, "The Significance Determination Process for Findings At

-Power," issue date June 19, 2012, using Exhibit 2, "Mitigating Systems Screening Questions." The finding screened as of very low safety significance (Green) because it was a design deficiency confirmed not to result in loss of operability. Specifically, the licensee performed an alternate operability determination

, which reasonably concluded the residual heat removal system was operable.

Because the finding also impacted the Barrier Integrity cornerstone, the inspectors also screened the finding through IMC 0609 Appendix A, Exhibit 3 , "Barrier Integrity Screening Questions." The finding screened as Green because it did not represent an actual open pathway in the physical integrity of reactor containment or involve an actual reduction in function of hydrogen igniters in the reactor containment.

The inspectors did not identify a cross

-cutting aspect associated with this finding because the finding was not confirmed to reflect current performance due to the age of the performance deficiency.

Enforcement

This finding did not involve enforcement action because no violation of regulatory requirements was identified.

The licensee entered this finding into its corrective action program as AR 2012-8187 and re-performed the operability evaluation (FIN 05000315/2013002

4OA7 Licensee Identified Violations

The following violation of very low significance (Green) or Severity Level IV was identified by the licensee and is a violation of NRC requirements which meets the criteria of the NRC Enforcement Policy for being dispositioned as an NCV.

The licensee identified a violation of 10 CFR 50.9, completeness and accuracy of information, for submitting a revised Emergency Action Level (EAL) scheme that was inaccurate in a material respect. While implementing the scheme, the licensee identified that CA7 and CS7 require indication of vessel level that is below the lowest measurement capability of installed instrumentation. Due to system configuration, NLI-1000, the reactor vessel level full range instrument, cannot measure below a level of 612.8 feet. This creates a condition where the instrument would indicate that vessel level remained at 612.8 even though inventory might be well below 612.8. Without that information, entry into CA7 or CS7 may not occur.

After identifying the error, the licensee determined that a change to the EAL to conform to the as-configured plant could not be made without prior NRC approval. The licensee also discussed the condition with the NRC staff and provided a letter on October 26, 2012 , regarding the error. The inspectors reviewed the information provided by the licensee and concluded that because the NRC approved the EAL and correction would require NRC approval, the erroneous information was material to the NRC and was a violation of 10 CFR 50.9. The inspectors reviewed the Enforcement Manual and Enforcement Policy and concluded that since the inaccurate information was identified

after it was relied on to be accurate to approve the EAL scheme, enforcement action was warranted. Because the violation did not conform to any examples of Severity Level 1 through III, and there were no willful aspects, the inspectors determined that the violation was of Severity Level IV. Because the licensee identified the error, the inspectors concluded that the violation could be treated as a licensee identified NCV.

The inspectors reviewed the issue under the Reactor Oversight Process and concluded that since the licensee had not implemented the inaccurate EAL s and the EAL scheme in effect remained viable, there was no Reactor Oversight Process aspect to the issue.
