SUMMARY

The U.S. Nuclear Regulatory Commission (NRC) continued monitoring the licensees performance by conducting an integrated inspection at Waterford Steam Electric Station, Unit 3, in accordance with the Reactor Oversight Process. The Reactor Oversight Process is the NRCs program for overseeing the safe operation of commercial nuclear power reactors. Refer to https://www.nrc.gov/reactors/operating/oversight.html for more information.

List of Findings and Violations

Failure to Establish Documented Work Instructions Appropriate to the Circumstance for the Safety-Related Wet Cooling Tower Fan Motors Cornerstone Significance Cross-Cutting Report Aspect Section Mitigating Green [P.2] - 71111.12 Systems NCV 05000382/2020003-01 Evaluation Open/Closed The inspectors reviewed a self-revealed Green finding and associated non-cited violation (NCV) of Technical Specification 6.8.1.a for the licensees failure to establish documented work instructions appropriate to the circumstance for the periodic inspection and cleaning of wet cooling tower fan motor support bulkhead drains. Specifically, the work instructions only allowed for observation of standing water in the bulkhead, but did not provide steps for verifying the drains were clear or cleaning the drains if necessary. As a result, standing water in the wet cooling tower 5A fan motor support bulkhead led to water intrusion of the motor casing, motor bearing failure, and inoperability of the fan and ultimate heat sink on May 13, 2020.

Additional Tracking Items

None.

PLANT STATUS

The Waterford Steam Electric Station, Unit 3, began the inspection period at 100 percent power.

The licensee initiated a plant shutdown on September 25, 2020, to begin Refueling Outage 23.

The unit remained shutdown for the remainder of the inspection period.

INSPECTION SCOPES

Inspections were conducted using the appropriate portions of the inspection procedures (IPs) in effect at the beginning of the inspection unless otherwise noted. Currently approved IPs with their attached revision histories are located on the public website at http://www.nrc.gov/reading-rm/doc-collections/insp-manual/inspection-procedure/index.html. Samples were declared complete when the IP requirements most appropriate to the inspection activity were met consistent with Inspection Manual Chapter (IMC) 2515, Light-Water Reactor Inspection Program - Operations Phase. The inspectors reviewed selected procedures and records, observed activities, and interviewed personnel to assess licensee performance and compliance with Commission rules and regulations, license conditions, site procedures, and standards.

Starting on March 20, 2020, in response to the National Emergency declared by the President of the United States on the public health risks of the coronavirus (COVID-19), resident and regional inspectors were directed to begin telework and to remotely access licensee information using available technology. During this time the resident inspectors performed periodic site visits each week, increasing the amount of time on site as local COVID-19 conditions permitted.

As part of their onsite activities, resident inspectors conducted plant status activities as described in IMC 2515, Appendix D; observed risk significant activities; and completed on site portions of IPs. In addition, resident and regional baseline inspections were evaluated to determine if all or portions of the objectives and requirements stated in the IP could be performed remotely. If the inspections could be performed remotely, they were conducted per the applicable IP. In some cases, portions of an IP were completed remotely and on site. The inspections documented below met the objectives and requirements for completion of the IP.

INSPECTION RESULTS

Failure to Establish Documented Work Instructions Appropriate to the Circumstance for the Safety-Related Wet Cooling Tower Fan Motors Cornerstone Significance Cross-Cutting Report Aspect Section Mitigating Green [P.2] - 71111.12 Systems NCV 05000382/2020003-01 Evaluation Open/Closed The inspectors reviewed a self-revealed Green finding and associated non-cited violation (NCV) of Technical Specification 6.8.1.a for the licensees failure to establish documented work instructions appropriate to the circumstance for the periodic inspection and cleaning of wet cooling tower fan motor support bulkhead drains. Specifically, the work instructions only allowed for observation of standing water in the bulkhead, but did not provide steps for verifying the drains were clear or cleaning the drains if necessary. As a result, standing water in the wet cooling tower 5A fan motor support bulkhead led to water intrusion of the motor casing, motor bearing failure, and inoperability of the fan and ultimate heat sink on May 13, 2020.

Description:

The ultimate heat sink consists of two 100 percent capacity loops, each consisting of a dry and wet cooling tower and water stored in the wet cooling tower basins.

Each wet cooling tower consists of two cells, and each cell is serviced by four induced draft fans, for a total of eight fans per wet cooling tower. With a wet cooling tower fan inoperable, the entire wet cooling tower must be declared inoperable, unless the inoperable fan has an approved cover installed. One wet cooling tower fan may be covered, and the ultimate heat sink remains operable per Technical Specification 3.7.4. A vibration switch mounted outside on the wet cooling tower fan motor duct causes an alarm in the control room on high fan motor vibration. During normal plant operations, the wet cooling towers operate to maintain the component cooling water system temperature. During accident conditions, the wet cooling towers operate until the dry cooling towers can dissipate the heat load from the component cooling water system.

In 2004, the licensee instituted required preventive maintenance task 10403 to inspect and clean the A wet cooling tower floor drains monthly. This task also included work instructions to inspect and clean the wet cooling tower fan motor support bulkhead drain in each wet cooling tower fan shroud. The intent of preventive maintenance task 10403, with respect to the motor support bulkheads, was to ensure the drains were clear so that water could not accumulate in the bulkhead after a rainfall event. Water accumulation (or standing water) in any bulkhead could mean partial immersion of that motor. The work instructions were two steps in total: 1) INSPECT bulkhead drain and CLEAN if needed and 2) IF discrepancy present that cannot be resolved by basic cleaning, INITIATE a CR [condition report] to address issue.

In February 2019, the licensee installed new motors for 15 of the16 wet cooling tower fans.

During performances of required preventive maintenance task 10403 between February 2019 and May 2020, the licensee identified eight separate instances of standing water in various A wet cooling tower fan motor bulkheads. Of these instances, the licensee identified standing water seven times in fan motor 5A, five times in fan motor 8A, and three times in fan motor 3A. The licensee identified standing water in all the A wet cooling tower fan motor bulkheads on at least one occasion during this period. Despite the intent of preventive maintenance task 10403 to clean the drains if needed, the licensee did not make any attempts within the performances of 10403 to clean the drains when they identified standing water. In each of these cases, the licensee initiated a new condition report or documented a reference to a condition report, which had previously been initiated in the work order. In all cases, the licensee documented the implementing work order for preventive maintenance task 10403 as complete although the licensee had not performed any cleaning. To address the standing water, the licensee-initiated work requests from each of the condition reports.

However, the licensee had not implemented any of the work requests as they were still in planning as of September 2020.

On May 13, 2020, the control room received an unexpected annunciator alarm indicating high vibrations on wet cooling tower fan motor 5A, which was one of the motors replaced in February 2019. The licensee collected vibration data on the fan motor and determined it indicated motor bearing damage. Subsequently, the licensee secured wet cooling tower fan 5A and opened its breaker due to the condition. The licensee then declared both the wet cooling tower fan 5A and the A ultimate heat sink inoperable. The plant entered Technical Specification 3.7.4 and cascading technical specifications, resulting in entry into an unplanned 72-hour shutdown limiting condition of operations. The following day, the licensee installed a cover over fan motor 5A and declared the A wet cooling tower and A ultimate heat sink operable, exiting the affected limiting conditions of operation.

The licensee sent wet cooling tower fan motor 5A to the motor vendor to perform a failure analysis. In its preliminary report, the vendor documented that water intrusion of the motor casing had caused the high vibration. Specifically, standing water on the exterior of the water, due to the clogged bulkhead drain, resulted in water entering the grease drain plug and stator cavity drain plug. The motor drains were designed to allow moisture to exit the motor. Consequently, water displaced the grease lubricant in the bearing, resulting in poor lubrication characteristics and bearing failure.

In a review of required preventive maintenance task 10403, the inspectors noted that it had numerous inadequacies. For example, the inspection of the bulkhead drains was limited to looking through a 3-inch viewport and identifying any standing water, but it does not permit actual viewing of the drain to ensure it is clear nor the ability to see inside the bulkhead for debris, which might migrate toward the drain and clog it. Additionally, the inspectors noted that no cleaning, even basic cleaning, could be performed using the instructions in preventive maintenance task 10403 given that access to the bulkhead is limited to the viewport and that any cleaning would require the licensee to secure the fan motor and erect scaffolding to ensure the necessary access, among other actions. Furthermore, the inspectors noted that the work instructions do not identify any objective criteria for determining the intent of the task is complete. Finally, the inspectors noted that standing water due to a clogged drain can evaporate between performances of preventive maintenance task 10403 (or the drain might be partially clogged, but still retain water while draining slowly), resulting in a condition where the motors could be partially immersed in water unbeknownst to the licensee. This is demonstrated by the identification of standing water in only some of the performances of 10403 without the licensee having performed any cleaning of the drains.

Corrective Actions: The licensee implemented an emergent work order to replace wet cooling tower fan motor 5A on May 27, 2020, and collected vibration data on the remaining wet cooling tower fan motors and determined the data was satisfactory. Additionally, the licensee lowered the alert/alarm limits for wet cooling tower fan motor vibration monitoring and initiated actions to correct the deficiencies in required preventive maintenance task 10403.

Corrective Action References: Condition Reports CR-WF3-2020-02188, CR-WF3-2020-03716, CR-WF3-2020-04493

Performance Assessment:

Performance Deficiency: The failure to establish documented instructions appropriate to the circumstance for the inspection and cleaning of the A wet cooling tower fan motor support bulkhead drains in accordance with NRC Regulatory Guide 1.33 was a performance deficiency.

Screening: The inspectors determined the performance deficiency was more than minor because it was associated with the equipment performance attribute of the Mitigating Systems Cornerstone and adversely affected the cornerstone objective to ensure the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. Specifically, as a result of the licensee not completing the intent of required preventive maintenance task 10403 on multiple occasions, the A wet cooling tower fan motors were subjected to periods of standing water in the motor support bulkheads which led to the failure of fan motor 5A and an unplanned entry into a 72-hour technical specification limiting condition for operation.

Significance: The inspectors assessed the significance of the finding using Appendix A, The Significance Determination Process (SDP) for Findings At-Power. The inspectors determined that the finding was of very low safety significance (Green) because

(1) the finding was not a deficiency affecting the design or qualification of a mitigating system;

(2) the degraded condition did not represent a loss of the PRA function of a single train technical specification system for greater than is technical specification allowed outage time;

(3) the degraded condition did not represent a loss of the PRA function of one train of a multi-train technical specification system for greater than its technical specification allowed outage time;

(4) the degraded condition did not represent a loss of the PRA function of two separate technical specification systems for greater than 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />;

(5) the degraded condition did not represent a loss of a PRA system and/or function as defined in the PRIB or licensees PRA for greater than 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />; and

(6) the degraded condition did not represent a loss of the PRA function of one or more non-technical specification trains of equipment designated as risk-significant in accordance with the licensees maintenance rule program for greater than 3 days.

Cross-Cutting Aspect: P.2 - Evaluation: The organization thoroughly evaluates issues to ensure that resolutions address causes and extent of conditions commensurate with their safety significance. Specifically, while the licensee initiated corrective actions through work requests to clean the bulkhead drains when standing water was identified during multiple performances of required preventive maintenance task 10403, the licensee did not evaluate the cause of the condition which was, ultimately, inadequate work instructions. Therefore, after the first identification of standing water in the bulkheads, the licensee had the opportunity to correct the work instructions in 10403 to allow completion of the task as intended for every future implementation of the task.

Enforcement:

Violation: Technical Specification 6.8.1.a, requires, in part, that procedures shall be established, implemented, and maintained covering the applicable procedures recommended in NRC Regulatory Guide 1.33, Revision 2. Appendix A to NRC Regulatory Guide 1.33, Section 9.a, requires, in part, that maintenance that can affect the performance of safety-related equipment be properly pre-planned and performed in accordance with written procedures, documented instructions, or drawings appropriate to the circumstances. The licensee established required preventive maintenance task 10403, in part, to inspect and clean the A wet cooling tower fan motor support bulkhead drains monthly.

Contrary to the above, between 2004 and May 2020, required preventive maintenance task 10403 was not appropriate to the circumstance because inspection and cleaning of the A wet cooling tower fan motor bulkhead drains could not be completed in accordance with the documented instructions. As a result, standing water in the wet cooling tower 5A fan motor support bulkhead between August 2019 and April 2020 led to water intrusion of the motor casing, displacement of grease lubricant, motor bearing failure, and inoperability of the fan and ultimate heat sink.

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