SUMMARY

Inspection Report 05000237/2016002, 05000249/2016002, 07200037/2016001; 04/01/2016 - 06/30/2016; Dresden Nuclear Power Station, Units 2 & 3; In-Plant Airborne Radioactivity Control and Mitigation. This report covers a 3-month period of inspection by resident inspectors; announced baseline inspections by regional inspectors; and an inspection by regional inspectors of operational activities associated with an Independent Spent Fuel Storage Installation (ISFSI) at the Dresden Nuclear Power Station, Units 2 and 3. One Green finding was identified by the inspectors. The finding involved a Non-Cited Violation (NCV) of the U.S. Nuclear Regulatory Commission (NRC)requirements. The significance of inspection findings is 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 April 29, 2015. Cross-cutting aspects are determined using IMC 0310, "Aspects Within the Cross-Cutting Areas," dated December 4, 2014. All violations of NRC requirements are dispositioned in accordance with the NRC's Enforcement Policy, dated February 4, 2015. The NRC's program for overseeing the safe operation of commercial nuclear power reactors is described in NUREG-1649, "Reactor Oversight Process," dated February 2014.

Cornerstone: Occupational Radiation Safety

Green.

A finding of very-low safety significance and an associated NCV of Title 10 of the Code of Federal Regulations (CFR), Part 20.1703, was an NRC-identified finding for failure to implement and maintain written procedures regarding breathing air quality that resulted in the failure to perform a continuous in-line breathing air quality test during filling of self-contained breathing apparatus (SCBA) cylinders since 2009. Specifically, on May 4, 2016, during an inspection of the licensee's air compressor, the inspectors identified that the in-line carbon monoxide (CO) detector located at the compressor high-pressure filling station was inoperable since 2009, the procedure does not specify an alternative method of CO monitoring during the filling of the SCBA cylinders. Without specifying an alternative method of monitoring and only relying on the high-temperature safety shut-off, hazardous CO gas could be introduced into the SCBA cylinders, thus degrading the Grade-D air quality, during a compressor malfunction. The licensee's corrective actions included but were not limited to revising the applicable procedures, servicing or replacing the CO monitor by the manufacturer, and installing a new air compressor at the facility. The inspectors determined that that the finding was more than minor in accordance with Inspection Manual Chapter (IMC) 0612, in that the finding impacted the program and process attribute of the Occupational Radiation Safety Cornerstone and adversely affected the cornerstone objective of ensuring adequate protection of worker health and safety from exposure to radiation through the use of SCBAs during an emergency response use by maintaining certified air quality. Specifically, the licensee failed to implement and maintain written procedures regarding an alternative method of monitoring air quality testing to maintain the Grade-D air quality during filling of SCBA cylinders. The finding was determined to be of very-low safety significance in accordance with IMC 0609, Appendix C, "Occupational Radiation Safety Significance Determination Process," because it was not an as-low-as-reasonably-achievable planning issue, there was no overexposure nor substantial potential for an overexposure, and the licensee's ability to assess dose was not compromised.

3 The inspectors concluded that the cause of the issue involved a cross-cutting component in the area of human performance, resources, in that, the license did not ensure the adequacy of the procedure describing the alternate methods of CO monitoring during filling of Grade D air into the SCBA cylinders. [H.1] (Section 2RS3).

REACTOR SAFETY

Cornerstones: Initiating Events, Mitigating Systems, and Barrier Integrity

1R01 Adverse Weather Protection

Main article: IP 71111.01

.1 Readiness for Impending Adverse Weather Condition-Severe Thunderstorm Watch with High Wind Conditions

a. Inspection Scope

Since thunderstorms with potential tornados and high winds were forecast in the vicinity of the facility for April 2

, 2016, the inspectors reviewed the licensee's overall preparations/protection for the expected weather conditions. The inspectors walked down the off-site power and reactor recirculation adjustable speed drive systems, in addition to the licensee's emergency alternating current (AC) power systems, 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 licensee 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 the licensee's 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. The inspectors also reviewed licensee thermography inspection results for the 345 KV switchyard following the high wind conditions to ensure no deficiencies were developed as a result of the extreme weather conditions. Additionally, the inspectors reviewed the Updated Final Safety Analysis Report (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 (CAP) items to verify that the licensee identified adverse weather issues at an appropriate threshold and dispositioned them through the CAP in accordance with station corrective action procedures. Documents reviewed are listed in the Attachment to this report.

5 This inspection constituted one readiness for impending adverse weather condition sample as defined in IP 71111.01-05.

b. Findings

No findings were identified.

.2 Readiness of Offsite and Alternate AC Power Systems

a. Inspection Scope

The inspectors verified that plant features and procedures for operation and continued availability of offsite and alternate AC pow er systems during adverse weather were appropriate. The inspectors reviewed the licensee's procedures affecting these areas and the communications protocols between the transmission system operator (TSO) and the plant to verify that the appropriate information was being exchanged when issues arose that could impact the offsite power system. Examples of aspects considered in the inspectors' review included:

coordination between the TSO and the plant during off-normal or emergency events;

explanations for the events;

estimates of when the offsite power system would be returned to a normal state; and

notifications from the TSO to the plant when the offsite power system was returned to normal. The inspectors also verified that plant procedures addressed measures to monitor and maintain availability and reliability of bot h the offsite AC power system and the onsite alternate AC power system prior to or during adverse weather conditions. Specifically, the inspectors verified that the procedures addressed the following:

actions to be taken when notified by the TSO that the post-trip voltage of the offsite power system at the plant would not be acceptable to assure the continued operation of the safety-related loads without transferring to the onsite power supply;

compensatory actions identified to be performed if it would not be possible to predict the post-trip voltage at the plant for the current grid conditions;

re-assessment of plant risk based on maintenance activities which could affect grid reliability, or the ability of the transmission system to provide offsite power; and

communications between the plant and the TSO when changes at the plant could impact the transmission system, or when the capability of the transmission system to provide adequate offsite power was challenged. The inspectors performed a walkdown of the 345 KV, 138 KV, and 34.5 KV switchyards and performed a review of maintenance history for components associated with the off-site power system. Documents reviewed are listed in the Attachment to this report. The inspectors also reviewed CAP items to verify that the licensee was identifying adverse weather issues at 6 an appropriate threshold and entering them into their CAP in accordance with station corrective action procedures. This inspection constituted one readiness of offsite and alternate AC power systems sample as defined in Inspection Procedure (IP) 71111.01-05.

b. Findings

No findings were identified.

1R04 Equipment Alignment

Main article: IP 71111.04

.1 Quarterly Partial System Walkdowns

a. Inspection Scope

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

unit 3 Division I low pressure coolant in jection/containment cooling service water (LPCI/CCSW) upon return to service from a preventative maintenance outage;

2/3B standby gas treatment (SBGT) w/ 2/3A SBGT out-of-service (OOS);

unit 2 high pressure coolant injection (HPCI) upon return to service following a corrective maintenance outage;

unit 2 isolation condenser (IC) with HPCI Inoperable; and

unit 3 IC after HPCI auxiliary oil pump fire 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, 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 five partial system walkdown samples as defined in IP 71111.04-05.

b. Findings

No findings were identified.

1R05 Fire Protection

Main article: IP 71111.05

.1 Routine Resident Inspector Tours

Main article: IP 71111.05Q

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:

Fire Zone 1.1.1.5A, unit 3 reactor building, elevation 589' (IC area);

unit 2 emergency diesel generator (EDG) carbon dioxide fire suppression system 2 year logic test;

Fire Zone 8.2.4, unit 3 cable tunnel, elevation 502';

Fire Zone 9.0.B, unit 3 diesel generator room, elevation 517'; and

Fire Zone 11.3, unit 2/3 crib house, elevations 509' and 517'. The inspectors reviewed areas and one fire protection suppression system test 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. Using 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 five quarterly fire protection inspection samples as defined in IP 71111.05-05.

b. Findings

No findings were identified.

1R06 Flooding

Main article: IP 71111.06

.1 Underground Vaults

a. Inspection Scope

The inspectors selected underground bunkers/manholes subject to flooding that contained cables whose failure could disable risk-significant equipment. The inspectors verified the licensee was performing periodic (bi-monthly for station blackout (SBO)manhole 1 and quarterly for SBO manhole 3) inspections. The inspectors accompanied 8 the licensee during a periodic inspection of the SBO manholes and noted that cables in SBO manhole 1 were submerged. The inspectors observed the licensee pump out water from the affected cable vault and ensured that the affected cables' splices were intact, and that appropriate cable support structures were in place. In security manholes 1 and 2, the inspectors verified that level alarm circuits were set appropriately to ensure that the cables would not be submerged. The inspectors also reviewed the licensee's corrective action documents with respect to past submerged cable issues identified in the corrective action program to verify the adequacy of the corrective actions. The inspectors performed a walkdown of the following underground bunkers/manholes subject to flooding:

SBO north and south manholes 1 and 3; and

security manholes 1 and 2.

Specific documents reviewed during this inspection are listed in the Attachment to this report. This inspection constituted one underground vaults sample as defined in IP 71111.06-05.

1R13 Maintenance Risk Assessments and Emergent Work Control

Main article: IP 71111.13

.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:

unit 3 emergent repairs to main generator stator water cooling temperature and pressure control instrument air piping;

unit 3 YELLOW risk with Division 1 LPCI/CCSW OOS;

emergent repairs to the 2/3 EDG due to a speed board control circuit failure;

unit 2 HPCI unavailable due to a steam leak with U2 LPCI previously unavailable; and

unit 3 HPCI inoperable due to auxiliary oil pump fire. 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. Documents reviewed during this inspection are listed in the Attachment to this report. These maintenance risk assessments and emergent work control activities constituted five samples as defined in IP 71111.13-05.

b. Findings

1R15 Operability Determinations and Functional Assessments

Main article: IP 71111.15

.1 Operability Evaluations

a. Inspection Scope

The inspectors reviewed the following issues:

historical operability of reactor protection system condenser low vacuum scram function with two channels out of technical specification tolerance;

breaker contact deficiency for MOV 2-2301-14 HPCI main pump recirculation to torus isolation valve;

impact of exceeding snubber alignment criteria on 2A reactor recirculation pump seismic support lug; and 14

reactor protection system (RPS) contacts latent failure with the potential to energize back-up scram valves. 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 appropriate sections of the TS and UFSAR 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 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 to this report. This operability inspection constituted four samples as defined in IP 71111.15-05.

b. Findings

No findings were identified.

a. Inspection Scope

The inspectors evaluated the licensee's implementation of their process used to identify, document, track, and resolve operational challenges. Inspection activities included, but were not limited to, a review of the cumulative effects of operator workarounds (OWAs)on system availability and the potential for improper operation of the system, for potential impacts on multiple systems, and on the ability of operators to respond to plant transients or accidents. The inspectors performed a review of the cumulative effects of OWAs. The documents listed in the Attachment were reviewed to accomplish the objectives of the inspection procedure. The inspectors reviewed both current and historical operational challenge records to determine whether the licensee was identifying operator challenges at an appropriate threshold, had entered them into their CAP, and proposed or implemented appropriate and timely corrective actions which addressed each issue. Reviews were conducted to determine if any operator challenge could increase the possibility of an Initiating Event, if the challenge was contrary to training, required a change from long-standing operational practices, or created the potential for inappropriate compensatory actions. Additionally, all temporary modifications were reviewed to identify any potential effect on the functionality of Mitigating Systems, impaired access to equipment, or required equipment uses for which the equipment was not designed. Daily plant and equipment status logs, degraded instrument logs, and operator aids or tools being used to compensate for material deficiencies were also assessed to identify any potential sources of unidentified operator workarounds.

15 This review constituted one operator workaround annual inspection sample as defined in IP 71115-02.

2RS3 In-Plant Airborne Radioactivity Control and Mitigation

Main article: IP 71124.03

.1 Engineering Controls (02.02)

a. Inspection Scope

The inspectors reviewed procedural guidance for use of ventilation systems, and assessed whether the systems were used, to the extent practicable, during high-risk activities to control airborne radioactivity and minimize the use of respiratory protection.

The inspectors assessed whether installed ventilation airflow capacity, flow path, and filter/charcoal unit efficiencies for selected systems were consistent with maintaining concentrations of airborne radioactivity in work areas below the concentrations of an airborne area to the extent practicable. The inspectors also evaluated whether selected temporary ventilation systems used to support work in contaminated areas were consistent with licensee procedural guidance and as-low-as-reasonably-achievable (ALARA). The inspectors reviewed select airborne monitoring protocols to assess whether alarms and set points were sufficient to prompt worker action. The inspectors assessed whether the licensee established trigger points for evaluating levels of airborne beta-emitting and alpha-emitting radionuclides. These inspection activities constituted one sample as defined in Inspection Procedure (IP) 71124.03-05 19

b. Findings

No findings were identified.

.2 Use of Respiratory Protection Devices (02.03)

a. Inspection Scope

The inspectors assessed whether the licensee provided respiratory protection devices for those situations where it was impractical to employ engineering controls such that occupational doses were ALARA. For select instances where respiratory protection devices were used, the inspectors assessed whether the licensee concluded that further engineering controls were not practical. The inspectors also assessed whether the licensee had established means to verify that the level of protection provided by the respiratory protection devices was at least as good as that assumed in the work controls and dose assessment. The inspectors assessed whether the 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 U.S. Nuclear Regulatory Commission (NRC). 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 (SCBA) bottles to assess whether the air used met or exceeded Grade D quality. The inspectors evaluated whether plant breathing air supply systems satisfied the minimum pressure and airflow requirements for the devices. The inspectors evaluated whether selected individuals qualified to use respiratory protection devices had been deemed fit to use the devices by a physician. The inspectors observed selected individuals donning, doffing, and functionally checking respiratory protection devices as appropriate and assessed whether these individuals knew how to safely use the device and how to properly respond to any device malfunction or unusual occurrence. The inspectors observed the physical condition of respiratory protection devices ready for issuance and reviewed records of routine inspection for selected devices. The inspectors reviewed records of maintenance on the vital components for selected devices and assessed whether onsite personnel assigned to repair vital components received vendor-provided training. These inspection activities constituted one sample as defined in IP 71124.03-05

b. Findings

Introduction:

The inspectors identified a finding of very-low safety significance (Green) and an associated NCV of Title 10 CFR, Part 20.1703, for failure to implement and maintain written procedures regarding breathing air quality which resulted in the failure to perform a continuous in-line breathing air quality test during filling of SCBA cylinders.

20 On May 4, 2016, the inspectors identified that the in-line carbon monoxide (CO) monitor located at the air compressor high-pressure fill station was not operational since 2009.

The procedure did not specify alternative methods of CO monitoring during filling of SCBA cylinders. Specifically, the licensee failed to adequately implement effective CO monitoring of the air used to fill SCBA cylinders.

Description:

On May 4, 2016, during a routine inspection of the Eagle Air compressor used to fill SCBA cylinders at the Dresden Nuclear Power Station, the inspectors identified that the in-line CO monitor located at the high pressure side of the filling station was out of service since 2009. This in-line CO gas monitor was installed by the manufacturer to monitor the oiled based lubricant air compressor, in the event of compressor failure. The licensee did perform periodic Grade D air testing of the air compressor (including CO). Station procedure RP-DR-827 specified alternate sampling must be performed when the installed in-li ne CO was out of service, however, this procedure does not adequately specify how this sampling was to be performed. The inspectors observed this sampling was performed on the inlet of the air compressor.

This practice did not adequately ensure the air quality on the outlet of the air compressor was acceptable. Specifically, there was no specific instruction where to place the monitor, and without a specific instruction, the licensee's technicians routinely placed this portable air monitor on the air intake section of the air compressor rather than the high pressure side of the compressor in-line with the cylinder filling station where the inoperative in-line CO monitor was located. The licensee determined that the alternative method as described on the procedure was adequate because the air compressor has a built-in a high temperature cut-off switch on the compressor side and at quarterly intervals, the compressor air quality was tested by an independent laboratory testing company to meet Grade-D air quality. Nevertheless, the inspectors determined that the compressor (Eagle-Air Breathing System) was an oil-lubricated compressor that has an installed in-line air filtration system that was capable of removing oil, water, particulates, objectionable taste and odors to meet Grade-D air standard for SCBA cylinders. However, it does not remove CO gas from the system caused by a malfunctioning air compressor. The high temperature sensor installed on the compressor detects ignition of lubricant by shutting off the compressor, the in-line CO monitor functioned as a redundancy system thus ensuring Grade D air quality was maintained by detecting a trace amount of CO gas in parts per million range. When the CO monitor was unavailable, the air compressor relied only on one single point of failure detection through the temperature sensor and a trace amount of CO may have been generated without any detection. The alternate method of detection stated in the procedure doesn't constitute a redundancy system because the alternate CO detector was routinely placed on the intake side of the compressor. Therefore, the alternate gas monitoring was incapable of detecting CO gas

during refilling of the SCBA cylinders when the air compressor/temperature sensor malfunctioned. As corrective actions, the licensee called the manufacturer, and a manufacturer representative was currently repairing the unit. Additionally, the licensee was also in the process of installing a new air Raven Eagle SCBA compressor system. The licensee indicated that in the interim, the licensee will perform sampling of current SCBA cylinders for carbon monoxide gas from past fillings.

Analysis:

The inspectors determined that this issue of concern was a performance deficiency because the licensee failed to effectively implement and maintain written procedures regarding breathing air quality which resulted in the failure to perform a continuous in-line breathing air quality test during filling of SCBA cylinders since 2009. Specifically, the in-line CO monitor was defective and out of service and the licensee did not implement an alternative method approved by the manufacturer to sample the air quality that was necessary to demonstrate compliance with the requirements of 10 CFR 20.1703. The inspectors determined that the cause of the performance deficiency was reasonably within the licensee's ability to foresee and correct and should

have been prevented. The finding was not subject to traditional enforcement since the incident did not have a significant safety consequence, did not impact the NRC's ability to perform its regulatory function, and was not willful. The inspectors also determined that that the finding was more than minor in accordance with Inspection Manual Chapter (IMC) 0612, in that the finding impacted the program and process attribute of the Occupational Radiation Safety Cornerstone and adversely affected the cornerstone objective of ensuring adequate protection of worker health and safety from exposure to radiation. Specifically, the less than adequate procedures to determine the air quality could result in unplanned and unintended contamination of the SCBA cylinders with CO gas originating from the air compressor. The inspectors also concluded that the potential consequence of CO contamination could cause an immediate danger to life or health condition for the SCBA wearer during a plant emergency response. The finding was assessed using IMC 0609, Appendix C, and Occupational Radiation Safety Significance Determination Process and was determined to be of very-low safety significance because it was not an ALARA planning issue, there was no overexposure nor substantial potential for an overexposure, and the licensee's ability to assess dose was not compromised. Consequently, the inspectors concluded that the cause of the issue involved a cross-cutting component in the area of human performance, resources in that, the licensee did not ensure the adequacy of the procedure describing the alternate methods of CO monitoring during the filling of Grade D air into the SCBA cylinders. [H.1]

Enforcement:

Title 10 CFR 20.1703 states, in part, that the licensee shall make use of individual respiratory protection equipment and to the extent practical shall implement and maintain a Respiratory Protection Program that includes written procedures regarding breathing air quality to be maintained at Grade-D air quality criteria (CO content to less than ten part per million). Contrary to the above, on May 4, 2016, the licensee failed to implement and maintain written procedures regarding breathing air quality which resulted in the failure to perform a continuous in-line breathing air quality test during filling of SCBA cylinders since 2009. Specifically, the in-line CO monitor was defective and out-of-service and the licensee did not implement an alternative method approved by the manufacturer to sample the air quality that was necessary to demonstrate compliance with the requirements of 10 CFR 20.1703. Since the failure to adequately implement and maintain a Respiratory Protection Program that includes written procedures regarding the breathing air quality to maintain Grade-D air quality criteria was of very-low safety significance, corrective actions were established as described above, and the issue was entered into the 22 licensee's Corrective Action Program as Issue Report (IR) 2666210, the violation is being treated as a NCV consistent with Section 2.3.2 of the NRC Enforcement Policy (NCV 05000237/2016002-01; 05000249/2016002-01; "Failure to Implement and Maintain Written Procedures Regarding Breathing Air Quality Testing").

.3 Self-Contained Breathing Apparatus for Emergency Use (02.04)

a. Inspection Scope

The inspectors reviewed the status and surveillance records for select SCBAs. The inspectors evaluated the licensee's capability for refilling and transporting SCBA air bottles to and from the control room and operations support center during emergency

conditions. The inspectors assessed whether control room operators and other emergency response and radiation protection personnel were trained and qualified in the use of SCBAs and evaluated whether personnel assigned to refill bottles were trained and qualified for that task. The inspectors assessed whether appropriate mask sizes and types were available for use. The inspectors evaluated whether on-shift operators had no facial hair that would interfere with the sealing of the mask and that appropriate vision correction was available. The inspectors reviewed the past two years of maintenance records for selected in-service SCBA units used to support operator activities during accident conditions. The inspectors assessed whether maintenance or repairs on an SCBA unit's vital components were performed by an individual certified by the manufacturer of the device to perform the work. The inspectors evaluated the onsite maintenance procedures governing vital component work to determine whether there was any inconsistencies with the SCBA

No findings were identified.

4OA2 Identification and Resolution of Problems

Main article: IP 71152

.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 28 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.

b. Findings

No findings were identified.

.2 Daily Corrective Action Program Reviews

a. Inspection 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.

b. Findings

No findings were identified.

.3 Semi-Annual Trend Review

a. Inspection Scope

The inspectors performed a review of the licensee's CAP and associated documents to identify trends that could indicate the existence of a more significant safety issue. The inspectors' review was focused on repetitive equipment issues, but also considered the results of daily inspector CAP item screening discussed in Section 4OA2.2 above, licensee trending efforts, and licensee human performance results. The inspectors' review nominally considered the 6-month period of January 2016 through June 2016, although some examples expanded beyond those dates where the scope of the trend

warranted. The review also included issues documented outside the normal CAP in major equipment problem lists, repetitive and/or rework maintenance lists, departmental 29 problem/challenges lists, system health reports, quality assurance audit/surveillance reports, self-assessment reports, and Maintenance Rule assessments. The inspectors compared and contrasted their results with the results contained in the licensee's CAP trending reports. Corrective actions associated with a sample of the issues identified in the licensee's trending reports were reviewed for adequacy. The inspectors and the licensee noted similar trends in program effectiveness and human performance standards. Although these deficiencies did not always result in any immediate adverse consequences, a potential trend in these areas is apparent and suggests that additional licensee attention to effect corrective actions may be appropriate. The licensee entered the following potential adverse trend into their CAP during this time period: Operations fundamental focus area self-assessment (FASA) deficiency (IR 2635948). Specific examples associated with degraded program effectiveness and human performance standards trends included, but were not limited to:

Not properly utilizing the CAP to capture, identify, and properly resolve degraded plant equipment in a timely manner (IR 2673322) as well instances where IRs and WOs were closed prematurely without correction of the identified problem (IR 2675223).

Failure to properly report MSPI EDG reliability failures (IR 2676458), but as no threshold was crossed, this issue was considered a minor violation of NRC requirements.

Failure to adequately document the completion of snubber inspections associated with the unit 2 core spray and isolation condenser systems (IR 2681869).

Inability to locate completion records for periodic radiation surveys on HI-STAR spent fuel dry storage casks. This issue was considered a minor violation of NRC requirements because the licensee successfully completed the surveillances when they were notified of the oversight by the inspectors (IR 2677592).

On April 17, 2016, while performing the Unit 2 quarterly average power range monitor (APRM) rod block and scram function surveillance, the operators received an unexpected alarm (Channel B Reactor Scram). This unexpected half scram (condition in which half of the necessary logic to achieve a scram actuated) was generated when the incorrect APRM mode switch was manipulated during routine testing. The APRM was returned to operate and the Channel B half scram was reset (IR 2656804).

On April 30, 2016, the licensee exceeded the drywell floor drain sumps (DWFDS) surveillance frequency for SR 3.4.4.1. The licensee immediately performed the surveillance and all unidentified drywell leakage was within TS required limits. The DWFDS are normally pumped every 8 hours9.259259e-5 days 0.00222 hours 1.322751e-5 weeks 3.044e-6 months and DWFDS were last pumped at 8:00 a.m. and would not be available for the next scheduled pumping at 4:00 p.m. due to scheduled maintenance. After review of TS limiting condition for operations (LCOs) the licensee made the assumption that pumping the sumps at 12:00 a.m.

(the next scheduled pumping) would be sufficient to meet a 24 hour2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months LCO. They did not verify their assumption and validate the Technical Specification Surveillance 30 Requirement per TRM Appendix I "Surveillance Frequency Control Program" which is a 12 hour1.388889e-4 days 0.00333 hours 1.984127e-5 weeks 4.566e-6 months LCO (IR 2663515). This issue was considered a minor violation of NRC requirements because the licensee successfully completed the surveillances when they identified the issue.

On May 17, 2016, the licensee inadvertently initiated the fire suppression deluge system when a maintenance technician took unauthorized resistance readings while attempting to troubleshoot an alarming condition with the fire detection system in the unit 2/3 crib house (IR 2670555). This review constituted one semi-annual trend inspection sample as defined in IP 71152-05.

b. Findings

No findings were identified.

4OA3 Follow-Up of Events and Notices of Enforcement Discretion

Main article: IP 71153

.1 (Closed) Licensee Event Report (LER) 05000237/2016-001-00, "Secondary Containment Differential Pressure Transient" On February 9, 2016, at 7:00 p.m. the operating heating boiler tripped offline.

At 7:15 p.m., main control room (MCR) operators received a reactor building differential pressure low alarm. Equipment operators were dispatched into the field and locally determined reactor building to outside environment differential pressure to be -0.35 inches water column. This is a low value as compared to the normal -0.65 inches water column but greater than the -0.25 inches water column required for Secondary Containment operability by the TS. Abnormal Operating Procedure DOA 5700-01, "Loss of Heating Boilers" was entered by the operators and reactor building ventilation supply plenum doors were opened in accordance with step D.8 of the procedure in order to prevent freezing of the reactor building ventilation supply plenum filters and cooling coils by allowing warm turbine building air to mix with the extremely cold outside air entering the system. In addition to the loss of the operating heating boiler, plant staff had previously identified that the unit 3 area differential pressure controller (3-5703-15B) was operating low out of tolerance which had the effect of not permitting the reactor building exhaust dampers from opening as far as would be expected based on supply air flow conditions. At 9:42 p.m., reactor building to outside environment differential pressure degraded to -0.24 inches water column. The combination of the colder, denser intake air and the open supply plenum doors lead to a greater quantity of air entering the reactor building ventilation supply system. This, along with the degraded exhaust differential pressure controller, resulted in reduced secondary containment vacuum conditions and an unplanned entry into secondary containment TS 3.6.4.1.A for not maintaining the required -0.25 inches water column vacuum inside the secondary containment boundary. Operators shutdown the degraded unit 3 reactor building ventilation system at 10:05 p.m. and vacuum conditions quickly recovered on the unit 2 reactor building ventilation system to in excess of -0.25 inches water column and TS 3.6.4.1.A was exited at 10:07 p.m. Corrective actions for this event included repairs to the affected differential pressure controller; implementation of a component monitoring strategy for the reactor building ventilation differential pressure controllers that focuses on controller output versus 31 secondary containment differential pressure in order to uncover masked performance issues; a revision to operations procedure DOA 5700-01 to incorporate lessons learned for a loss of heating boiler coincident with a degraded reactor building ventilation system; and a review of the differential pressure controller design and surveillance frequency. The licensee reported this event in accordance with 10 CFR 50.73(a)(2)(v)(C), any event or condition that could have prevented the fulfillment of the safety function of structures or systems that are needed to control the release of radioactive material. No findings or violations of NRC requirements were identified. This LER is closed.

This event follow up review constituted one sample as defined in IP 71153-05.

.2 Alert Declared Due to Fire in Unit 3 HPCI Auxiliary Oil Pump Motor

a. Inspection Scope

The inspectors reviewed the plant's response to the following: On June 27, 2016 during an operability surveillance, the Unit 3 HPCI system auxiliary oil pump (AOP) was discovered on fire. The fire was extinguished and the breaker for the AOP motor was turned off. Based on initial assessment of the event and meeting the Emergency Action Level (EAL) threshold criteria an Alert, MA5, was declared at 10:50 a.m. The Alert was terminated at 1:19 p.m. The HPCI system was declared inoperable and Technical Specification 3.5.1 condition G was entered, requiring HPCI to be operable within 14 days. The Licensee will submit a LER within 60 days per

10 CFR 50.73 and the inspectors will perform an event follow-up review in a future

report. Documents reviewed are listed in the Attachment to this report. This event follow-up review does not constitute a sample as defined in IP 71153-05.

4OA5 Other Activities

.1 Operation of an ISFSI at Operating Plants (60855.1)

a. Inspection Scope

The inspectors observed and evaluated select licensee loading, processing, and transfer operations of the fourth canister during the licensee's 2016 dry fuel storage campaign to verify compliance with the applicable Certificate of Compliance (CoC) conditions, the associated Technical Specifications, and approved Independent Spent Fuel Storage Installation (ISFSI) procedures. Specifically, the inspectors observed: placement of the multi-purpose canister (MPC) within the transfer cask (HI-TRAC) into the spent fuel pool, loading of fuel assemblies into the MPC; decontamination and surveying; welding and non-destructive testing of the MPC lid-to-shell weld; draining of water from the MPC;

vacuum drying of the MPC; welding and non-destructive testing of the MPC closure rings; and transfer of the MPC from the HI-TRAC to storage cask (HI-STORM). The licensee used the Holtec International HI-STORM 100 Cask System for this campaign.

32 The inspectors reviewed procedures used to perform ISFSI preparation, loading, sealing, transfer, monitoring, and storage activities. The inspectors also reviewed applicable heavy loads procedures and inspection documentation to determine compliance with the site's heavy loads program. Select documents, in part, were reviewed after the licensee completed certain loading activities. The inspectors reviewed the licensee's evaluations associated with fuel characterization and selection for storage. The licensee did not plan to load any damaged fuel assemblies or fuel debris during this campaign. The inspectors reviewed the canister fuel selection packages for the 2016 campaign to verify that the licensee was loading fuel in accordance with the CoC-approved contents.
