INSPECTION RESULTS

Observation: Integrating Radiological Information during the Biennial Emergency 71114.01 Preparedness Exercise The inspectors observed that the emergency response organization could be more effective in integrating available radiological information about plant conditions during the March 5, 2019, exercise. Specifically, the emergency response organization was slow to recognize that a change in protective action recommendations was required when the wind shifted after the General Emergency declaration. Information was available that radiological conditions were worsening and that protective action guides were exceeded at 2 miles downwind. If that information had been used to evaluate the newly-affected downwind sector, the emergency response organization could have promptly recognized that a change in protective action recommendations was necessary, even if there was not enough information to completely define the change. A prompt recognition might have caused the dose assessment staff to take different actions and allowed the subsequent protective action recommendation to be developed more quickly. The inspectors observed that the dose assessment staff relied upon dose assessment reports as the sole indicator of the need to make protective action recommendations. The staff did not appear to apply all available radiological information to inform their understanding of the need for protective measures as the situation changed.

Observation: Emergency Response Organization Did not consider Manual Dose 71114.01 Assessments during an Exercise The inspectors observed that the emergency response organization did not consider performing a dose assessment using manual inputs when the wind shifted after the General Emergency declaration during the March 5, 2019, emergency preparedness exercise. The licensee has the capability to perform dose assessment with manual inputs and that method might have resulted in the subsequent protective action recommendation being developed more quickly. However, the inspectors observed there was no discussion in the dose assessment group about the possible benefits of the manual method, and there was no intentional decision made to wait for the next data update before performing a new dose assessment. The inspectors discussed the manual dose assessment method with licensee staff following the exercise and concluded that dose assessment staff had a bias against using the manual method and were unlikely to consider its use under other circumstances.

Observation: Repeat Performance Issues Observed during Second Emergency 71114.06 Response Drill The inspectors observed an Emergency Response Organization (ERO) Mini-Drill in the Emergency Operations Facility on June 11, 2019. The inspectors observed many of the weaknesses described as observations from the NRC graded evaluation that was performed in March 2019, but the teams observations appear above in this report. During this drill, the licensee was not able to completely and satisfactorily demonstrate the emergency classification and protective action recommendation skills.

The licensee did self-identify the missed opportunities during their critique and entered them into the corrective action program. The licensee also took immediate corrective actions to suspend qualifications and provide remedial training to ERO position players whose actions and decision making led to the unsatisfactory performance during the drill.

Furthermore, the licensee is continuing to evaluate the ongoing recent ERO drill performance issues at a high level and is taking action to provide additional training to ERO staff as well as scheduling additional drill opportunities in 2019-2020 to provide ERO staff an opportunity to improve proficiencies and verify their continuing capability to ensure adequate protection of public health and safety during an emergency.

Observation: Operator Human Performance Issue in Challenging the Unknown 71152 The inspectors have noted a trend amongst plant operators when confronted with a scenario with unknown conditions and/or uncertain consequences. The inspectors reviewed the licensees Standards and Expectations with respect to Questioning Attitude, and determined that the operators were not exhibiting fundamental human performance characteristics when it involved situations where the conditions were unknown. Their literature states that an attribute of a questioning attitude is challenging the unknown and individuals are expected to stop when faced with uncertain conditions. However, the inspectors have noted three instances where this was not demonstrated.

• On February 20, 2019, the Unit 3 operators discovered that the diesel fuel oil transfer pump B was inoperable which resulted in making the diesel generator B inoperable. In response, the control room was conducting a common cause test to verify that the diesel generator A was operable. The operators decided to make use of a procedure that would only test the operability of the diesel fuel oil transfer pump A. The inspectors questioned whether this would also cause diesel generator A to be inoperable. Despite this question, the control room proceeded to use the procedure to test the diesel fuel oil transfer pump A. An in-depth inspection found that the use of the procedure did cause a period where both trains of diesel generators were inoperable.

• On February 20, 2019, the Unit 3 diesel generator B was declared inoperable when the diesel fuel oil transfer pump B tripped shortly after starting (planned diesel fuel oil transfer pump B test). The licensee discovered a significant amount of water intrusion into the diesel fuel oil vault. This had the effect of causing excessive condensation in the fuel oil transfer pump junction box grounding the internal terminal board. Prior to this date, routine entries into diesel fuel oil vault B noted water leakage into the vault as evidenced by the presence of standing water. These were documented in condition reports (CR) 18-02885, 08-08777, and 18-18808. Additionally, two of these condition reports were classified as Not a Condition Adverse to Quality (NCAQ).

• On February 13, 2019, Unit 3 control room identified that the keying of a hand-held radio used by plant operators would affect the temperature controller for the train B control room emergency air temperature control system. The decision was made to keep the train inoperable (system was made inoperable for control valve corrective maintenance the day before). A prompt operability determination on February 14, 2019, (with input from the engineering department) determined that the system was operable/degraded. The total time between discovering this condition to when it was evaluated to be operable/degraded was approximately 20 hours2.314815e-4 days <br />0.00556 hours <br />3.306878e-5 weeks <br />7.61e-6 months <br />. During this time, two shifts of control room operators did not question whether the continued use of handheld radios should be a concern to other equipment, nor did they check to see if this affected the train A controller as instructed in Procedure 40DP-9OP26, Operations Condition Reporting Process and Operability Determination/Functional Assessment, step 4.1.1.J.

The licensee has taken corrective action to address each of these three instances. The inspectors have communicated this trend to the licensee and will continue to monitor plant performance for any further trends.

Failure to Develop Testing Program for Fuel Transfer Tubes Cornerstone Significance Cross-Cutting Report Aspect Section Mitigating Green None 71111.08P Systems NCV 05000528, 05000529,05000530/2019002-01 Open/Closed The inspectors identified a Green non-cited violation of 10 CFR Part 50, Appendix B, Criterion XI, Test Control. Specifically, the licensee did not establish testing requirements and acceptance limits to detect degradation of the fuel transfer tubes as required by 10 CFR Part 50, Appendix B, Criterion XI. Failure to detect degradation of the fuel transfer tube could result in the fuel transfer tube being rendered inoperable and unable to meet its safety-related functions. The licensee entered this issue into their corrective action program as Condition Report 19-06854.

Description:

During a review of the boric acid corrosion control program, the inspectors noted that a boric acid leak had been identified on the expansion joints for the fuel transfer tube outer housing, by design, the space between the fuel transfer tube and the expansion bellows is dry. The inspectors questioned the source of the boric acid. Procedure 70TI-9ZC01, Revision 21, Section 1.3, requires that the source of a boric acid leak be identified. Contrary to this requirement, the inspectors noted that the source of the boric acid leak from the fuel transfer tube bellows had never been identified. The inspectors asked for the latest test results on the fuel transfer tube to verify pressure boundary integrity. The licensee stated that no testing had been performed on the fuel transfer tube since initial construction.

Based upon a review of the Combustion Engineering Standard Safety Analysis Report and the Update Final Safety Analysis Report, the Fuel Transfer Tube Assembly has four Safety Related, Quality Related (Q) functions, including decay heat removal for the spent fuel pool and the reactor during the Fuel Transition Mode of Refueling Operations under a scenario where a loss of off-site power is assumed in conjunction with a single mechanical failure.

During this mode of operation when the core is being off loaded or re-loaded, the spent fuel pool cooling system may be augmented by one train of shutdown cooling (using either the low pressure spray injection (LPSI) or containment spray (CS) Pump) and associated auxiliaries. The shutdown cooling train in service is aligned such that it would provide cooling to both the reactor core and the spent fuel pool. Flow through the Fuel Transfer Tube PCE-M01 is credited for heat removal purposes in this case. This function was part of DMWO 00793132, Fuel Transfer Tube Assembly Subcomponent Reclassification, which was implemented in 1997. When the design and licensing basis of the Fuel Transfer Tube PCE-M01 was changed to credit it as a decay heat removal pathway, the Fuel Transfer Tube PCE-M01 and the associated Fuel Transfer Tube Assembly subcomponents were not reclassified as required by the guidance established in Regulatory Guide 1.26, Revision 1 to which the licensee is committed.

And Radioactive-Waste-Containing Components Of Nuclear Power Plants, Revision 1, Section C.1.b, states in part that systems or portions of systems important to safety that are designed for reactor shutdown or residual heat removal should be classified as Quality Group B. Implementation of Work order DMWO 00793132, which credited the fuel transfer tube with decay heat removal function, should have resulted in the fuel transfer tube being designated as a Quality Group B component.

Corrective Actions: The licensee has entered the issue into their corrective action program and requested Sargent & Lundy to develop this study to document the bases for the classification of the subcomponents that make up the Fuel Transfer Tube Assembly. The licensee is developing plan to locate the source of the boric acid leak and make necessary repairs, as well as determine a testing program for the fuel transfer tube.

Condition Report 19-06854

Performance Assessment:

Performance Deficiency: Contrary to the requirements of 10 CFR Part 50, Appendix B, Criterion XI, Test Controls, the licensee failed to develop a testing program for the fuel transfer tubes to ensure it remained capable of performing its functions under design conditions.

Screening: The inspectors determined the performance deficiency was more than minor because if left uncorrected, it would have the potential to lead to a more significant safety concern. The inspectors determined the performance deficiency was more than minor because if left uncorrected, it would have the potential to lead to a more significant safety concern. The failure to perform the required testing of the fuel transfer tubes is a performance deficiency. The performance deficiency is more than minor because it is associated with the protection against external factors attribute of the Mitigating Systems Cornerstone, and affects the cornerstone objective to ensure availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequence.

Specifically, the licensee failed to perform examinations/testing required to provide reasonable assurance that the fuel transfer tube could perform its intended function during design basis events, and therefore, maintain the ability to provide cooling to the irradiated fuel assemblies. Using NRC Inspection Manual Chapter 0609, Appendix G, Attachment 1, Exhibit 3, Mitigating Systems, the inspectors determined the finding is of very low safety significance (Green) because the finding did not involve the loss of operability or functionality of the component.

Significance: The inspectors assessed the significance of the finding using Appendix G, Shutdown Safety SDP. Using NRC Inspection Manual Chapter 0609, Appendix G, 1, Exhibit 3, Mitigating Systems, the inspectors determined the finding is of very low safety significance (Green) because the finding was related to the qualification of the component and the component remained operable or functional.

Cross-Cutting Aspect: None The finding was not assigned a cross cutting aspect because of the age of the issue and it is not indicative of current plant performance.

Enforcement:

Violation: Title 10 CFR Part 50, Appendix B, Criterion XI, Test Control, requires, in part, that a test program shall be established to assure that all testing required to demonstrate that systems, structures, and components will perform satisfactorily in service is identified and performed in accordance with written procedures which incorporate the requirements and acceptance limits contained in applicable design documents. Contrary to the above, from initial commercial operations until May 2019, the licensee failed to establish a test program to assure that all testing, required to demonstrate that the fuel transfer tubes will perform satisfactorily in service, was identified and performed in accordance with written procedures which incorporate the requirements and acceptance limits contained in applicable design documents. Specifically, the licensee did not establish examinations and testing required by 10 CFR Part 50 Appendix B, Criterion XI, Test Control, to detect degradation of the fuel transfer tube. Since the violation is of very low safety significance and is documented in the licensees corrective action program as Condition Report 19-06854, it is being treated as a non-cited violation, consistent with Section 2.3.2.a of the Enforcement Policy.

Enforcement Action: This violation is being treated as a non-cited violation, consistent with Section 2.3.2 of the Enforcement Policy.

Unresolved Item Design and Testing of the Fuel Oil Transfer System 71111.20 (Open) 05000528, 05000529,05000530/2019002-02

Description:

While observing excavation efforts for repairs to leaking domestic water piping the inspectors noted that there were three pipes uncovered, but that the workers had only expected two pipes to be in the location. A review of site drawings identified the third line as non-safety related piping that connected the safety related diesel fuel oil systems to each other as well as the bulk fuel oil system and associated loads in the water treatment facility.

The emergency Diesel Generator fuel oil transfer system was designed to Section III, Subsection ND of the ASME Code. The Updated Final Safety Analysis Report, Section 1.8 states that the licensee is committed to Regulatory Guide 1.137, Fuel-Oil Systems For Standby Diesel Generators, Revision 1. Section B, item e of Regulatory Guide states in part, e. Section 7.3 of ANSI N195-1976, Fuel-Oil Systems For Standby Diesel Generators, states that the arrangement of the fuel-oil system shall provide for inservice inspection and testing in accordance with ASME Boiler and Pressure Vessel Code,Section XI, Rules for Inservice Inspection of Nuclear Power Plant Components. For those portions of the fuel-oil systems for standby diesel generators that are designed to Section III, Subsection ND of the Code, an acceptable method of meeting the requirements of Section 7.3 is to ensure that the system arrangement would allow:

(1) Pressure testing of the fuel-oil system to a pressure 1.10 times the system design pressure at 10-year intervals. In the case of storage tanks, recommendations of the tank vendor should be taken into account when establishing the test pressure.

(2) A visual examination to be conducted during the pressure test for evidence of component leakages, structural distress, or corrosion. In the case of buried components, a loss of system pressure during the test constitutes evidence of component leakage.

Company Correspondence ID#: 450-00575 Date: 06/18/2018, indicates that the licensee shifted to an alternative pressure test for the buried portions of the diesel fuel oil transfer system. The licensee cited ASME Section XI paragraph IWA-2240 for the proposed ultrasonic examination to determine the fuel level in the fill line. The licensee stated as justification that, ASME Code Section XI, IWA-2240 ALTERNATIVE EXAMINATIONS states, Alternative examination methods, a combination of methods, or newly developed techniques may be substituted for the methods specified in this Division, provided the Inspector is satisfied that the results are demonstrated to be equivalent or superior to those of the specified method.

In addition, ANSI N195-1976, Fuel-Oil Systems For Standby Diesel Generators, section 5.3, Multiple Reactor Unit Nuclear Stations, states in part, Multiple reactor unit nuclear stations should be designed with completely independent fuel oil systems for each unit.

Inspectors had the following questions regarding the diesel fuel oil transfer systems associated with all three units.

a. The inspector requested the licensee demonstrate that the alternative method provided results that were equivalent or superior to the method specified in Section XI of the ASME Code.

b. The inspector had questions as to whether the use of isolation valves DFBV069, DFBV021, and DFAV015 was an adequate alternative to the requirement in ANSI N195-1976, Fuel-Oil Systems For Standby Diesel Generators, section 5.3, Multiple Reactor Unit Nuclear Stations, states in part, Multiple reactor unit nuclear stations should be designed with completely independent fuel oil systems for each unit, given that the licensee is treating these valves as Category B in their IST program and Design Calculation 13-MC-DF-0306, As Built Calculation for Sizing the Diesel Fuel Storage and Day Tanks, has zero leakage allowance from these valves.

Planned Closure Actions: Review documents provided by the licensee as they are available.

Licensee Actions: The inspectors did not perceive any immediate safety or security concerns. The licensee documented the unresolved item in Condition Reports 19-05734 and 19-05914.
