1R07 Heat Sink Performance
.1 Annual Heat Sink Performance (7111.07A - 1 sample)
a. Inspection Scope
The inspectors reviewed the containment spray system I heat exchangers' readiness and availability to perform its safety functions. The inspectors reviewed the design basis for the component and verified Exelon's commitments to NRC Generic Letter 89-13, "Service Water System Requirements Affecting Safety-Related Equipment." The inspectors reviewed the results of previous inspections of the containment spray system I heat exchangers. The inspectors discussed the results of the most recent inspection with engineering staff and reviewed pictures of the as-found and as-left conditions. The inspectors verified that Exelon initiated appropriate corrective actions for identified deficiencies. The inspectors also verified that the number of tubes plugged within the heat exchanger did not exceed the maximum amount allowed.
b. Findings
No findings were identified.
.2 Triennial Heat Sink Performance
a. Inspection Scope
Triennial Heat Sink and Heat Exchanger Sample Selection Based on the Oyster Creek risk ranking of safety-related heat exchangers, past triennial heat sink inspections, recent operational experience, and resident inspector input, the inspectors selected the containment spray system heat exchangers, the reactor building closed cooling water system heat exchangers, the ultimate heat sink, piping, intake screens, pumps and valves, the emergency service water system, chemical corrosion and bio-control, and the isolation condensers for inspection samples. For the samples selected, the inspectors reviewed the system layout, program reports, daily heat exchanger status and trend flow, differential pressure data, self-assessments, and maintenance methods (inspection, cleaning, maintenance, and performance monitoring) used to ensure heat removal capabilities for the safety-related heat exchangers and ultimate heat sink and compared them to Exelon's commitments made in response to NRC Generic Letter 89-13, "Service Water System Problems Affecting Safety-Related Equipment," dated July 18, 1989, and Supplement 1, dated April 4, 1990. Service Water System (Ultimate Heat Sink Sample) The inspectors completed an inspection of the service water system in accordance with the applicable steps of Inspection Procedure 71111.07, Sections 02.02(d)(4), 02.02(d)(5), 02.02(d)(6), and 02.02(d)(7). The service water system transfers heat from the reactor building closed cooling water heat exchangers to the intake structure. The inspectors reviewed recent buried piping inspections to assess the condition and structural integrity of the service water piping. The inspectors reviewed a sample of service water pipe nondestructive examination records, intake structure silt inspections, structures monitoring inspection results, and associated engineering evaluations to ensure that Exelon's staff was appropriately addressing observed degradation in service water piping and the intake structure. The inspectors observed that the service water unavailability was low, and that the system was available to perform its ultimate heat sink safety function. Additionally, a previous plant modification had provided for the use of the emergency service water system as an alternate pathway for service water. The inspectors reviewed the operation of the service water system. The review included system design changes, system procedures, intake structure operating procedures, abnormal service water operating procedures, loss of the service water intake structure operation procedure, adverse weather condition procedures, and service water leak isolation procedures. The inspectors verified that Exelon's staff was maintaining design drawings, design basis calculations, and operating procedures consistent with their design and licensing basis and that plant operators could reasonably implement the procedures. The inspectors performed a walkdown of the accessible portions of the service water system and the intake structure to verify that instrumentation relied upon by operators for decision making tasks was available and functional.
The inspectors verified that the service water piping had been analyzed to demonstrate resistance to water hammer susceptibility. Also, the inspectors verified Exelon's in-service test procedures tested for the correct operation of the service water pump discharge check valves, precluding the potential for weak-pump/strong-pump interaction during system operation. The inspectors reviewed the visual inspection records for recent cleanings of the containment spray system and reactor building closed cooling water heat exchangers, which were performed to verify the structural integrity and fouling condition of the heat exchangers. The inspectors reviewed Exelon's staff disposition process for active through wall service water piping leaks, including structural evaluations and completed and/or planned corrective actions. Microbiologically induced corrosion has not been evident in service water piping systems at Oyster Creek. Ultrasonic testing examinations were appropriately performed in accordance with American Society of Mechanical EngineersSection XI, Boiler and Pressure Vessel Code, and American Society of Mechanical Engineers Code Case N-513-2. The inspectors concluded that the engineering evaluations and the ultrasonic testing examinations demonstrated that structural integrity was maintained. The inspectors verified that Exelon's staff established appropriate chemistry procedures to control, detect, and monitor system degradation due to macrofouling of the service water and emergency service water pumps, valves, and piping. Chlorination treatment of the service water system was controlled, monitored, trended, and evaluated to ensure adequate biotic control. The inspectors reviewed the service water system performance testing to verify that the minimum calculated service water flow rates were maintained to essential equipment and met the acceptance criteria in the UFSAR. The inspectors performed a walkdown of the intake building (including the trash racks, service water pumps, service water traveling water screens, emergency service water pumps, and structural supports) and the accessible areas of the intake building containing service water piping to look for indications of piping leakage and/or degradation. The inspectors verified that intake structure pump bay silt accumulation was monitored, trended, and maintained at an acceptable level. The inspectors interviewed the cognizant system engineers, and reviewed silt deposition inspection records and results of past bay silt measurements. Emergency Service Water System The inspectors reviewed the emergency service water system and its containment spray heat exchangers in accordance with the applicable steps of Inspection Procedure 71111.07, Sections 02.02(b)(2) and 02.02(c). The containment spray heat exchangers provide cooling to the containment spray system should it be necessary to cool the drywell volume, and as an alternate pathway to the service water system, provides backup capability to cool the torus water during normal plant operation.
The inspectors reviewed the design basis heat removal calculation for a containment spray heat exchanger and sampled a heat balance test used to establish the heat exchanger cleanliness or fouling factor. The inspectors reviewed the design basis heat capacity calculation for this system. The inspectors verified that containment spray heat exchanger condition and operation were consistent with design assumptions in the plant's heat transfer calculations. The design and operation of the containment spray heat exchangers has been analyzed for potential water hammer effects, and plant operating procedures to assure that the heat exchanger does not experience damage due to water hammer conditions. Isolation Condenser Heat Exchanger (Heat Exchanger Sample) The inspectors reviewed the isolation condenser heat exchangers in accordance with the applicable steps of Inspection Procedure 71111.07, Sections 02.02(b)(2) and 02.02(c). These two heat exchangers with two tube bundles, in each, provide for reactor system cooling when steam is not producing power and are cooled by the evaporation of water supplied by the demineralization system with a backup supply available from the condensate storage system. The chemistry of the heat exchanger water was maintained at primary water chemistry quality to prevent corrosive degradation. The inspectors reviewed the heat removal capability of the system, the valve lineup for normal and abnormal conditions, and observed the heat exchangers, piping, and valves in the plant. Problem Identification and Resolution The inspectors selected and reviewed a sample of corrective action program reports related to the heat sink equipment and heat exchanger samples chosen for this inspection. The review verified whether Exelon's staff were appropriately identifying, characterizing, and correcting problems related to these systems and components, and that the planned or completed corrective actions for the reported issues were appropriate.
b. Findings
No findings were identified.
1R11 Licensed Operator Requalification Program and Licensed Operator Performance
Quarterly Review of Licensed Operator Requalification Testing and Training
a. Inspection Scope
The inspectors observed licensed operator simulator training on October 17, 2017, which included an off gas system deflagration with a loss of a service water pump, seal failure on a reactor recirculation pump, and manual reactor scram. The inspectors evaluated operator performance during the simulated event and verified completion of risk significant operator actions, including the use of abnormal and emergency operating procedures. The inspectors assessed the clarity and effectiveness of communications, implementation of actions in response to alarms and degrading plant conditions, and the oversight and direction provided by the control room supervisor. The inspectors verified the accuracy and timeliness of the emergency classification made by the shift manager and the technical specification action statements entered by the shift technical advisor. Additionally, the inspectors assessed the ability of the crew and training staff to identify and document crew performance problems.
b. Findings
No findings were identified.
1R12 Maintenance Effectiveness
a. Inspection Scope
The inspectors reviewed the samples listed below to assess the effectiveness of maintenance activities on structure, system, and component performance and reliability. The inspectors reviewed system health reports, corrective action program documents, maintenance work orders, and maintenance rule basis documents to ensure that Exelon was identifying and properly evaluating performance problems within the scope of the maintenance rule. For each sample selected, the inspectors verified that the structure, system, or component was properly scoped into the maintenance rule in accordance with Title 10 of the Code of Federal Regulations (10 CFR) 50.65 and verified that the (a)(2) performance criteria established by Exelon staff was reasonable. As applicable, for structures, systems, and components classified as (a)(1), the inspectors assessed the adequacy of goals and corrective actions to return these structures, systems, and components to (a)(2). Additionally, the inspectors ensured that Exelon staff was identifying and addressing common cause failures that occurred within and across maintenance rule system boundaries.

1R13 Maintenance Risk Assessments and Emergent Work Control
a. Inspection Scope
The inspectors reviewed station evaluation and management of plant risk for the maintenance and emergent work activities listed below to verify that Exelon performed the appropriate risk assessments prior to removing equipment for work. The inspectors selected these activities based on potential risk significance relative to the reactor safety cornerstones. As applicable for each activity, the inspectors verified that Exelon personnel performed risk assessments as required by 10 CFR 50.65(a)(4) and that the assessments were accurate and complete. When Exelon performed emergent work, the inspectors verified that operations personnel promptly assessed and managed plant risk. The inspectors reviewed the scope of maintenance work and discussed the results of the assessment with the station's probabilistic risk analyst to verify plant conditions were consistent with the risk assessment. The inspectors also reviewed the technical specification requirements and inspected portions of redundant safety systems, when applicable, to verify risk analysis assumptions were valid and applicable requirements were met.

1R22 Surveillance Testing
a. Inspection Scope
The inspectors observed performance of surveillance tests and/or reviewed test data of selected risk-significant structures, systems, and components to assess whether test results satisfied technical specifications, the UFSAR, and Exelon procedure requirements. The inspectors verified that test acceptance criteria were clear, tests demonstrated operational readiness and were consistent with design documentation, test instrumentation had current calibrations and the range and accuracy for the application, tests were performed as written, and applicable test prerequisites were satisfied.
Upon test completion, the inspectors considered whether the test results supported that equipment was capable of performing the required safety functions. The inspectors reviewed the following surveillance tests: 636.4.003, No. 1 emergency diesel generator load test on October 3, 2017 (routine test) 607.4.015, Containment spray and emergency service water system II pump operability, in-service test, and containment spray pumps trip on October 25, 2017, (routine test) 604.3.001, Reactor building to torus power vacuum breaker test and calibration on November 14, 2017 (routine test) 602.4.004, Main steam isolation valve 10% closure test on November 27, 2017, (containment isolation valve test)
b. Findings
No findings were identified. Cornerstone: Emergency Preparedness
1EP4 Emergency Action Level and Emergency Plan Changes
a. Inspection Scope
Exelon implemented various changes to the Oyster Creek Emergency Action Levels (EALs), Emergency Plan, and Implementing Procedures. Exelon had determined that, in accordance with 10 CFR 50.54(q)(3), any change made to the EALs, Emergency Plan, and its lower-tier implementing procedures, had not resulted in any reduction in effectiveness of the Plan, and that the revised Plan continued to meet the standards in 50.47(b) and the requirements of 10 CFR Part 50, Appendix E. The inspectors performed an in-office review of all EAL and Emergency Plan changes submitted by Exelon as required by 10 CFR 50.54(q)(5), including the changes to lower-tier emergency plan implementing procedures, to evaluate for any potential reductions in effectiveness of the Emergency Plan. This review by the inspectors was not documented in an NRC Safety Evaluation Report and does not constitute formal NRC approval of the changes. Therefore, these changes remain subject to future NRC inspection in their entirety. The requirements in 10 CFR 50.54(q) were used as reference criteria.
b. Findings
No findings were identified.
RADIATION SAFETY
Cornerstone:
Occupational and Public Radiation Safety
2RS2 Occupational As Low As Is Reasonably Achievable
a. Inspection Scope
The inspectors assessed Exelon's performance with respect to maintaining occupational individual and collective radiation exposures as low as is reasonably achievable (ALARA). The inspectors used the requirements contained in 10 CFR 20, Regulatory Guides 8.8 and 8.10, technical specifications, and procedures required by technical specifications as criteria for determining compliance. Verification of Dose Estimates and Exposure Tracking Systems (1 sample) The inspectors reviewed the current annual collective dose estimate, basis methodology, and measures to track, trend, and reduce occupational doses for ongoing work activities. The inspectors also reviewed ALARA work activity evaluations, exposure estimates, exposure reduction requirements, person-hour estimates, results achieved (dose rate reductions, actual dose), and post-job reviews that were conducted to identify lessons learned. The inspectors reviewed post-job ALARA evaluations for some of the high dose jobs and verified that lessons learned had been entered into Exelon's corrective action program.
b. Findings
No findings were identified.
2RS3 In-Plant Airborne Radioactivity Control and Mitigation
a. Inspection Scope
The inspectors reviewed the control of in-plant airborne radioactivity and the use of respiratory protection devices in these areas. The inspectors used the requirements in 10 CFR 20, Regulatory Guides 8.15 and 8.25, NUREG/CR-0041, technical specifications, and procedures required by technical specifications as criteria for determining compliance. Use of Respiratory Protection Devices (1 sample) The inspectors reviewed the adequacy of Exelon's use of respiratory protection devices in the plant to include applicable ALARA evaluations, respiratory protection device certification, respiratory equipment storage, air quality testing records, and individual qualification records.
Self-Contained Breathing Apparatus for Emergency Use (1 sample) The inspectors reviewed the status and surveillance records for three self-contained breathing apparatus' (SCBAs) staged in-plant for use during emergencies, Exelon's SCBA procedures and maintenance and test records, the refilling and transporting of SCBA air bottles, SCBA mask size availability, and the qualifications of personnel performing service and repair for this equipment.

===.3 Radiological Effluent Technical Specification/Offsite Dose Calculation Manual Radiological Effluent Occurrences (1 sample)
a. Inspection Scope
The inspectors sampled Exelon submittals for the radiological effluent technical specifications and Offsite Dose Calculation Manual radiological effluent occurrences performance indicator for the period of October 1, 2016, through September 30, 2017. The inspectors used performance indicator definitions and guidance contained in NEI Document 99-02, Revision 7 to determine if performance indicator data was reported properly. The inspectors reviewed the public dose assessments for the performance indicator for public radiation safety to determine if related data was accurately calculated and reported. The inspectors reviewed the corrective action program database to identify any potential occurrences such as unmonitored, uncontrolled, or improperly calculated effluent releases that may have impacted offsite dose. The inspectors reviewed gaseous and liquid effluent summary data and the results of associated offsite dose calculations to determine if indicator results were accurately reported.
b. Findings
No findings were identified.
4OA2 Problem Identification and Resolution
=
.1 Routine Review of Problem Identification and Resolution Activities
a. Inspection Scope
As required by Inspection Procedure 71152, "Problem Identification and Resolution," the inspectors routinely reviewed issues during baseline inspection activities and plant status reviews to verify Exelon's entered issues into the corrective action program at an appropriate threshold, gave adequate attention to timely corrective actions, and identified and addressed adverse trends. 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 corrective action program and periodically attended condition report screening meetings. The inspectors also confirmed, on a sampling basis, that, as applicable, for identified defects and non-conformances, Exelon performed an evaluation in accordance with 10 CFR 21.
b. Findings
No findings were identified.
.2 Semi-Annual Trend Review
a. Inspection Scope
The inspectors performed a semi-annual review of site issues to identify trends that might indicate the existence of more significant safety concerns. As part of this review, the inspectors included repetitive or closely-related issues that may have been documented by Exelon in trend reports, site performance indicators, major equipment problem lists, system health reports, maintenance rule assessments, and maintenance or corrective action program backlogs. The inspectors also reviewed Exelon's corrective action program database for third and fourth quarters of 2017 to assess condition reports written in various subject areas (equipment problems, human performance issues, etc.), as well as individual issues identified during the NRC's daily condition report review.
b. Findings
No findings were identified. The inspectors evaluated a sample of corrective maintenance backlogs, control room deficiency tags, open operability evaluations, and operator workarounds. The inspectors verified that these issues were addressed within the scope of the corrective action program.
.3 Annual Sample:
Use of Portable Radioactive Liquid Storage Tanks in Response to an Off-Normal Event
a. Inspection Scope
The inspectors reviewed Exelon's actions associated with the use of portable liquid storage tanks (i.e., "FRAC" tanks) in response to an unplanned water intrusion on multiple levels in the reactor building on September 22, 2016, as documented in action request 2718867. The water intrusion was caused by leakage of radioactively contaminated water from the refueling cavity through the primary containment bellows seal during a refueling outage activity. The water overwhelmed the capacity of the chemical waste treatment system to store the water prior to processing. A total of five FRAC tanks were ultimately connected to the radioactive waste system, and water was transferred into the tanks via a fire-hose. The tanks were located outdoors, but within a posted radiologically controlled area. Each tank was positioned within its own temporary leakage containment. The inspectors assessed Exelon's problem identification threshold, cause analyses, extent of condition reviews, compensatory actions, and the prioritization and timeliness of Exelon's corrective actions to determine whether Exelon was appropriately identifying, characterizing, and correcting problems associated with this issue, and to determine whether the planned or completed corrective actions were appropriate. The inspectors compared the actions taken to the requirements of Exelon's corrective action program and 10 CFR 50, Appendix B, as applicable.
b. Findings and Observations
No findings were identified.
The inspectors determined that the addition of portable FRAC tanks to the chemical waste treatment system involved a temporary facility change that was not described in the UFSAR and was in response to a nonconforming or degraded condition (i.e., an off-normal event with unexpected reactor cavity leakage that overwhelmed the capacity of the radwaste processing system). 10 CFR 50.59(d)(1) requires that "The licensee shall maintain records of changes in the facility, changes in procedures, and of tests and experiments made pursuant to paragraph (c) of this section. These records must include a written evaluation which provides the bases for the determination that the change, test, or experiment does not require a license amendment pursuant to paragraph (c)(2) of this section." The inspectors identified that, contrary to 10 CFR 50.59, no 50.59 evaluation of the acceptability of a temporary change to the Oyster Creek chemical waste treatment system processing facility was made. Section 4.4 of NEI 96-07, "Guidelines for 10 CFR 50.59 Evaluations," Revision 1, endorsed by the NRC in Regulatory Guide 1.187, titled "Applying 10 CFR 50.59 to Compensatory Actions to Address Nonconforming or Degraded Conditions" specifies that, "If an interim compensatory action is taken to address the condition and involves a temporary procedure or facility change, 10 CFR 50.59 should be applied to the temporary change. The intent is to determine whether the temporary change/compensatory action itself-impacts other aspects of the facility or procedures described in the UFSAR-" The Oyster Creek UFSAR, Section 15.7.3, "Postulated Radioactive Releases Due to Liquid Tank Failures," describes an accident for which doses for the failure of radioactive liquid storage tanks are estimated at the site boundary.
Oyster Creek Technical Specification 3.6.C provides a limit on the amount of radioactivity allowed in two specific outdoor tanks in order to ensure that the potential dose to a member of the public remains within limits. These tanks are mentioned explicitly because they are located outdoors and are non-seismically qualified.
The inspectors identified Exelon did not follow 10 CFR 50.59(d)(1) because no screening or evaluation was completed to determine that the change does not require a license amendment was conducted for the temporary facility change in September 2016. Also, no records (in the form of work orders or temporary configuration change packages) were generated or maintained for the temporary facility change in September 2016. Because 10 CFR 50.59 violations could potentially impede or impact the regulatory process, they are evaluated under the NRC's traditional enforcement approach. The NRC Enforcement Manual, Section 2.1.3.D.5.a, indicates that such violations would be considered more than minor if the activity or change would have required prior NRC review and approval. This type of issue is also described in Appendix E of the Enforcement Manual as "minor changes to requirements" and is considered to be a minor violation. A review of 10 CFR 50.59 screening for a similar use of temporary FRAC tanks in 2006 (OC-2006-S-0301) indicates that prior NRC review and approval would not have been required and therefore is considered a minor violation. Exelon wrote issue report 4075886 on November 17, 2017, to document and correct this condition. The inspectors determined that Exelon's corrective actions were appropriate, commensurate with the safety significance of the issue, and timely.
4OA3 Follow-Up of Events and Notices of Enforcement Discretion
(Closed) Licensee Event Report (LER) 05000219/2016-005-01: Technical Specification Prohibited Condition Caused by One Electromatic Relief Valve Inoperable for Greater than Allowed Outage Time On September 19, 2016, during the 1R26 refueling outage with the reactor in cold shutdown, as-found testing was performed on all five electromatic relief valves. The 'E' electromatic relief valve failed to open from the main control room and no indication was observed. Upon investigation, the cutout switch in the valve actuator was found stuck in the open position, preventing the solenoid from actuating to open the valve. Exelon determined the cause of the 'E' electromatic relief valve failure to open was due to missing lock washers not installed on the cut-out switch assembly. Without the lock washers installed, the hinge pins interfered with the solenoid frame holes, which created mechanical binding. Based on this information, Exelon concluded that one of the five electromatic relief valves was inoperable longer than the technical specification allowed outage time of 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />. This LER was revised to include additional descriptive information related to the failure of the 'E' electromatic relief valve and subsequent corrective actions. The inspectors reviewed this issue in NRC Inspection Report 05000219/2016004, Section
4OA2 and identified one finding.
The inspectors did not identify any violations or new issues during the review of Revision 1 of the LER. This LER is closed.
4OA6 Meetings, Including Exit
On January 10, 2018, the inspectors presented the inspection results to Mr. Timothy Moore, Site Vice President, and other members of the Oyster Creek staff. The inspectors verified that no proprietary information was retained by the inspectors or documented in this report.
