INSPECTION RESULTS

Unresolved Item (Closed) Seabrook Station Use and Application of Technical Specifications URI 05000443/

2017 002-01 711 11.15 Operability Determinations Description

Following the issuance of the subject unresolved item, the resident inspectors coordinated with the Agency's office of Nuclear Reactor Regulation to determine the correct application of NextEra Seabrook's Technical Specifications (TS). In particular, using NRR office instruction COM

-106, a task interface agreement (ML18093B444)was initiated to evaluate the Seabrook TS related to the impact of an inoperable cooling water tower on its supported systems. This task interface agreement was intended to be used as the primary information source to inform the assessment and subsequent closure of the unresolved item.

The unresolved item identified the following specific examples of concern:

1) On June 9 through June 10, 2015 (approximately 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />), and on October 13, 2016 (approximately 18 hours2.083333e-4 days <br />0.005 hours <br />2.97619e-5 weeks <br />6.849e-6 months <br />), both trains o f cooling tower service water were inoperable for cooling water tower basin cleaning and inspection while in Mode 1. For this support system, NextEra entered the TS Action 3.7.4.c that provides an allowed outage time of 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> to restore at least one train to OPERABLE status or be in hot shutdown Mode 4 within 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> and cold shutdown Mode 5 within the following 30 hours3.472222e-4 days <br />0.00833 hours <br />4.960317e-5 weeks <br />1.1415e-5 months <br /> (108 total hours). Upon inoperability of this support system (ultimate heat sink), NextEra did not declare the supported systems (primary component cooling water and the emergency diesel generators) inoperable and enter the associated TS Actions. If determined to be applicable, TS 3.7.3 and TS 3.8.1 would have required being in Mode 3 within 7 and 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br />, and Mode 5 within 37 and 38 hours4.398148e-4 days <br />0.0106 hours <br />6.283069e-5 weeks <br />1.4459e-5 months <br /> total, respectively.

2) On April 19, 2017, with the 'B' emergency diesel generator already inoperable, the 'A' cooling water tower loop was removed from service to replace portions of its cooling water tower pump discharge piping while the plant was in Mode 6 (refueling) with less than 23 feet of water above the reactor flange. Limiting Condition for Operability 3.7.4 (SW / UHS) only applies in Modes 1, 2, 3, and 4. Before the transition to Mode 6, the 'B' emergency diesel generator had been rendered inoperable for planned maintenance and testing while the plant was defueled and with no applicable operational mode. In Modes 5 and 6, Limiting Condition for Operability 3.8.1.2 requires one OPERABLE emergency diesel generator and TS 3.0.4 requirements were met for entering Mode 6, in part, because of the operable 'A' emergency diesel generator. While in Mode 6, both trains of ocean SW were operable to supply cooling water. At the time, the inspectors interpreted that Seabrook's licensing basis required each emergency diesel generator to be supported by its train of seismically qualified cooling water. If it is assumed that a seismically qualified source of cooling water was required on April 19, when the 'A' cooling water tower loop was removed from service, its supported system, the 'A' emergency diesel generator may have been rendered inoperable for a period of approximately 10 hours1.157407e-4 days <br />0.00278 hours <br />1.653439e-5 weeks <br />3.805e-6 months <br /> at the same time as the 'B' emergency diesel generator was inoperable for maintenance. Additionally, the inspectors identified a second potential operability concern associated with the residual heat removal system. Specifically, in Mode 6, Limiting Condition for Operability 3.9.8.2 requires two OPERABLE independent residual heat removal loops while the water level is less than 23 feet above the top of the reactor vessel flange. With less than the required residual heat removal loops OPERABLE, Action 3.9.8.2 requires immediate initiation of corrective action to return the required loops to OPERABLE status, or to establish greater than or equal to 23 feet of water above the reactor vessel flange, as soon as possible. This condition may have existed because the 'A' cooling water tower loop was inoperable, which could be interpreted to have resulted in the

'A' residual heat removal loop being inoperable for approximately 65 hours7.523148e-4 days <br />0.0181 hours <br />1.074735e-4 weeks <br />2.47325e-5 months <br /> while the plant was in Mode 6 with less than 23 feet of water above the reactor flange.

To resolve this interpretation of TS rules of usage and the literal definition of operability and its impact on support and supported systems, Region 1 requested assistance from the headquarters program office through the submittal of task interface agreement 2017

-001, dated July 20, 2017. This process was used to answer specific questions germane to the underlying issues raised in the unresolved item, and to effectively leverage applicable expertise in the areas of reactor systems and TS, while maintaining consistency with applicable rules, regulations, and the licensing history of the plant.

This task interface agreement was used to verify the correct implementation of the Seabrook Station, Unit No. 1 TS for supported systems, when one or more of its support systems (e.g. cooling water) is not operable per the definition in the TS. This issue was identified during a routine baseline inspection and was characterized as an unresolved item in NRC Integrated Inspection Report 05000443/2017002.

The task interface agreement response (ML18093B444) addressed two specific questions:

(1) Does TS license amendment No. 32 from October 1994 ( ML011800279), provide latitude for NextEra Seabrook to remove the entire cooling tower portion of the ultimate heat sink for 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br />, and,

(2) If TS license amendment No. 32 allows the flexibility to remove both loops of cooling tower service water for 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br />, is the current TS language consistent with this flexibility?

The remaining two issues noted in the unresolved item are closely linked to the resolution of these two questions and as such are indirectly answered by the Task Interface Agreement.

As indicated previously, the Task Interface Agreement was used to answer the underlying licensing basis compliance issues associated with two, specific examples of concern documented in unresolved ite m 2017-002-01. Upon review of the formally

-issued Task Interface Agreement response, the two questions were resolved as follows:

1) Seabrook License Amendment No. 32 on the service water system/UHS operability requirements does give NextEra the latitude to remove the entire cooling tower from service for 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> without evaluation of the operability of the supported systems. The evaluation prepared for Amendment No. 32 and accepted by the NRC staff demonstrated that the service water cooling tower is not important to overall plant safety during the 72 hour8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> allowed outage time permitted to restore the cooling tower to OPERABLE status, and, thus, it is not needed to support key safety

-related systems during that period. The conclusion that the service water cooling tower is not needed for operability of supported equipment is reasonable because the service water pump house and associated service water loops would be operable for cooling of supported equipment and the probability of occurrence of a design basis event for which the pump house is not qualified (i.e., a design

-basis seismic event) would be extremely low during the 72 hour8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> allowed outage time window. This logic applies to other support systems where the overall plant safety has been evaluated through a license amendment review and found acceptable by the NRC staff for the duration of the allowed outage time (e.g., the structure, system or components supported by the emergency diesel generators when out of service for the completion time evaluated for Amendment No. 97).

2) The current TS language is consistent with this flexibility because the definition of operability included in the TS requires functionality of only those support systems necessary for the structure, system or components to perform its safety function as specified in the design and licensing basis of the facility. The evaluations and analyses supporting the design and licensing bases establish the conditions when a support system is necessary for operability of the supported structure, system or component. The license amendment request supporting Amendment No. 32 proposed specific allowed outage times for inoperable cooling water system structure, system or components for preventive and corrective maintenance to improve system reliability. The supporting analyses provided by the licensee for this amendment request evaluated the effect of the out

-of-service cooling water system structure, system or components, including the cooling tower and the cooling water loops circulating through the tower, on the safety of the facility and showed that the support of the service water cooling tower was not necessary during the limited maintenance window. Review of the design and licensing basis of plant safety evaluations is typically required to understand the conditions where support systems are necessary for the supported system to complete its specified safety function. The NRC staff approved the proposed TS changes as stated in the staff's safety evaluation. Therefore, the current T S language is consistent with the flexibility provided by Amendment No. 32

. The evaluation conducted under the task interface agreement does, however, raise two additional issues, involving immediate implications of this determination and applicable generic issues:

1) Immediate Implications: Pursuant to the requirements of 10 CFR 50.71(e), the licensee should evaluate whether the safety analysis report has been appropriately updated to reflect the effects of Amendment No. 32 to the Seabrook Operating License (ML18151A472)

.

Observations 71152 Annual Follow-up of Selected Issues The inspectors selected fire protection systems for follow-up based on recurring issues with fire detectors and the age related degradation of the fire pumps. The issues identified with fire detectors are generally related to the receipt of nuisance alarms in the main control room. The concerns with the fire pumps are age

-related degradation and long term loss of pump capacity. Based on the most recent test s, the fire pumps are meeting the required capacities but with some loss of original design margin. The inspectors reviewed condition reports, long term action plans, operator logs, and procedures, interviewed responsible engineers for the fire protection system and operators, and attended daily plant status meetings and troubleshooting team meetings.

In order to address the fire detectors, Seabrook used an established fleet procedure to implement a formal failure investigation process and execute a special focus troubleshooting team. The ongoing goal of the team is to identify and prioritize the specific issues relating to the fire detectors and provide the appropriate corrective action to fix the underlying problems.

To address the fire pump degradation , the planning and implementation is being coordinated via the fleet long term action management program using established fleet procedures. Based on the most recent pump performance, the station is scheduled to replace the pump before its performa nce degrades to an unacceptable level.

For these two fire protection issues , Seabrook currently is meeting their licens e condition s with respect to fire protection and there are no immediate safety concerns. Additionally, Seabrook is implementing or has scheduled appropriate corrective actions in accordance with their corrective action program commensurate with the significance of the identified issues.

2) Generic Implications: The issue addressed in this Task Interface Agreement response is specific to the Seabrook licensing basis and is not directly applicable to other facilities or licensees due to the unique facility design.

Corrective Actions: NextEra Seabrook

(1) entered the underlying issue into the corrective action program;

(2) implemented standing operating order 17

-002. (This order provided interim guidance to control room licensed operators for the application of TS actions to address support and supported systems and applicable actions, as warranted.);

(3) submitted a license amendment request (ML18151A472), on May 29, 2018 to the Agency

, to add a TS Section 3.0.6 limiting condition for operation that addresses such situations, to provide clarity and direction and formally integrate the standing operating order into Seabrook programs, processes and procedures, including a safety function determination program; and,

(4) discussed this upcoming license amendment request during a public teleconference (ML18099A308 and ML18135A246) with the NRC on April 24, 2018.

Corrective Action Reference(s): AR 2183029, AR 2190552, and AR 2239758 Closure Basis: Because the Task Interface Agreement answered the underlying TS compliance issues raised in the original, specific examples of concern in the unresolved item, there were no violations of regulatory requirements identified; therefore, this unresolved item is closed.
