Executed on Q CJD blr 'l 1--th , 2017 Sincerely, Eric McCartney Regional Vice President NextEra Energy Seabrook, LLC cc: NRC Region I Administrator NRC Project Manager, Project Directorate I-2 NRC Senior Resident Inspector Enclosed CD Listing: CD 1, 39 files, 556,838,912 bytes CD 2, 3 files, 50,049,024 bytes Seabrook Station 10 CFR 50.59 Report, Enclosure 1 Enclosure 1 to SBK-L-17157 Summary Report of Facility Changes, Tests, and Experiments Completed in Accordance with the Requirements of 1 OCFR50.59 for Revision 18 of the Updated Final Safety Analysis Report Seabrook Station 10 CFR 50.59 Report, Enclosure 1 Design Change Evaluations Design changes documented in the following Engineering Changes (EC) were installed during the period covered by the 10 CPR 50.59 Report. A 10 CPR 50.59 evaluation was performed for the ECs identified below. For each of the evaluations performed, there were no activities requiring prior NRC approval identified. 10CFR50.59 Evaluation 15-003 EC 282582, Fukushima Flex Portable Equipment Storage Summary Description and Purpose: In accordance with Seabrook's response to NRC Order EA-12-049 involving the Fukushima event, EC 282582 provides the design changes necessary to permit storage of FLEX portable equipment within the existing safety related Service Water Pump House (SWPH). The FLEX portable equipment is stored primarily on the largely unused Unit 2 side of the SWPH. Evaluation Summary: A 10 CPR 50.59 screening was performed and the following three (3) items screened in and required performance of a 50.59 evaluation:
- 1. A deviation in UFSAR-described methodology for the design of a new tornado missile barrier by Barrier 1 outside of the South wall of the Service Water Pump House (SWPH). 2. A partial impact to the UFSAR-described design function for the SWPH structure to provide tornado missile protection due to structural design changes made to the SWPH alcove per this EC. 3. UFSAR Section 3.5.2 describes the systems, structures and components (SSCs) to be protected from externally generated missiles and describes the Service Water Pump House as a missile-protected structure.
The probabilistic method used demonstrates the likelihood a missile will penetrate the missile barrier is less probable than the acceptable level of 10-6 per year. However, the design function is adversely affected as it is theoretically possible for a missile to pass the barrier. Therefore, the design function, and the fact that the SWPH is not 100% protected from externally generated missiles is evaluated for adverse effects. The subject activities use newer and accepted nuclear industry codes and standards to qualify a new type (at Seabrook Station) of missile barrier. The changes in methodology used for the new barrier design are consistent with NEI 96-07 guidance and are thus not departures in methodology. The appropriate qualification of the missile barrier ensures its ability to perform its design function of protecting the CAT I Service Water Pump House, and safety related SSCs contained therein, from design basis tornado generated missiles, and the probabilistic risk evaluation performed demonstrates an acceptably (per the UFSAR established limit of 10-6) low likelihood that a missile would pass the missile barrier at the Southeast comer of the SWPH. There is no potential to increase the probability or consequences of an accident or to impact the 1of3 Seabrook Station 10 CFR 50.59 Report, Enclosure 1 ability to achieve or maintain the safe shutdown of the unit. The evaluation concluded that the modification did not require prior NRC approval. 10CFR50.59 Evaluation 16-002 EC 287668, Temporary Jumper Across 1-EDE-B-1-A Cell #42 Summary Description and Purpose: EC 287668 provided the details for the installation of a temporary jumper across a degraded cell (#43) and approves the operation of Vital Battery I-EDE-B-I-A with only 58 connected cells. Evaluation Summary: A 10 CPR 50.59 screening was performed and the following item screened in and required performance of a 50.59 evaluation:
- 1. The design function of the safety-related batteries is to provide the sources of power for direct current load groups, vital control and instrumentation systems, and control and operation of Class IE and non-Class IE electrical equipment.
A reduction in battery capacity can adversely impact the capability of the battery to perform its intended design function. One impact of the battery capacity reduction from this change is the additional requirement for DC load shedding in order to maintain the capability of the battery in a crosstie configuration for the SBO 4-hour coping duration. Since UPSAR Section 8.3 .2. I .d presently states that load shedding is not required to meet the four-hour Station Blackout duration, the proposed activity to revise procedures to include mandatory DC load shedding is considered to adversely affect the method of performing or controlling the battery design function. The I 0 CPR 50.59 evaluation concluded that all Technical Specification parameter values associated with battery I-EDE-B-I-A are still conservatively bounding for the 58 cell configuration. The evaluation concluded that the modification did not require prior NRC approval. 10CFR50.59 Evaluation 16-004 EC 287860, Change to OS1023.10, Service Water Pumphouse Ventilation System Operation, to Allow Manual Control of the Pumphouse Ventilation System Summary Description and Purpose: OS I 023 .10, Service Water Pumphouse Ventilation System Operation was revised to include instructions for manual operation of the SWA fans/dampers to enhance ambient cooling of the service water pump motors as required. Operator actions during periods of manual control will ensure that the design basis environmental temperature requirements for the SW pumps are not exceeded. Evaluation Summary: A I 0 CPR 50.59 screening was performed and the following item screened in and required performance of a 50.59 evaluation:
- 1. The subject procedure revision allows manual operation of the SW pumphouse air handling system in place of automatic operation as required to enhance ambient cooling 2of3 Seabrook Station 10 CFR 50.59 Report, Enclosure 1 of the service water pump motors and as such alters the method of controlling the SW pumphouse air handling system design function.
This change was a temporary substitution of manual action for automatic action to compensate for a degraded condition as discussed in NEI 96-07, Rev. 01. With the SWPH Ventilation system controlled within the normal environmental limits of the Service Environment Chart, there will be no impact on the operation of the service water system, or any other system. All systems, other than SWPH Ventilation will operate as designed and as assumed in the safety analyses. The evaluation concluded that the change did not require prior NRC approval. 3 of 3 Seabrook Station 10 CFR 50.59 Report, Enclosure 2 Enclosure 2 to SBK-L-17157 Summary of Changes to the Updated Final Safety Analysis Report Incorporated Using the Guidance ofNEI 98-03, "Guidelines for Updating Final Safety Analysis Reports Seabrook Station 10 CPR 50.59 Report, Enclosure 3 The following provides a summary of changes incorporated in Revision 18 of the Updated Final Safety Analysis Report using the guidance contained in NEI 98-03, "Guidelines for Updating Final Safety Analysis Reports."
