3 PLANT STATUS The unit began the inspection period at rated thermal power. On January 4, 2018, operators scrammed the unit based on an anticipated loss of offsite power during a winter storm. The unit was returned to rated thermal power on January 11, 2018. On January 25, 2018, operators down powered the unit to 45 percent for a planned repair to a drain valve in the moisture separator drain tank. The operators returned the unit to rated thermal power the same day. On March 4, 2018, operators lowered power to 50 percent to perform a thermal backwash of the main condenser after the March 2, 2018 nor'easter. Operators returned the unit to rated thermal power on March 5, 2018. On March 6, 2018, operators shutdown the unit to perform repairs to the fifth point feedwater heater. On March 13, 2018, the site lost all offsite alternating current power during a nor'easter while the unit was in cold shutdown, and the startup transformer experienced an electrical fault during the storm. The unit remained in cold shutdown for the remainder of the inspection period to address issues in the switchyard.

3 PLANT STATUS The unit began the inspection period at rated thermal power. On January 4, 2018, operators scrammed the unit based on an anticipated loss of offsite power during a winter storm. The unit was returned to rated thermal power on January 11, 2018. On January 25, 2018, operators down powered the unit to 45 percent for a planned repair to a drain valve in the moisture separator drain tank. The operators returned the unit to rated thermal power the same day. On March 4, 2018, operators lowered power to 50 percent to perform a thermal backwash of the main condenser after the March 2, 2018 nor'easter. Operators returned the unit to rated thermal power on March 5, 2018. On March 6, 2018, operators shutdown the unit to perform repairs to the fifth point feedwater heater. On March 13, 2018, the site lost all offsite alternating current power during a nor'easter while the unit was in cold shutdown, and the startup transformer experienced an electrical fault during the storm. The unit remained in cold shutdown for the remainder of the inspection period to address issues in the switchyard.

SUBJECT:

PILGRIM NUCLEAR POWER STATION - INTEGRATED INSPECTION REPORT 05000293/2018001

Dear Mr. Sullivan:

On March 31, 2018, the U.S. Nuclear Regulatory Commission (NRC) completed an inspection at Pilgrim Nuclear Power Station (PNPS). On April 25, 2018, the NRC inspectors discussed the results of this inspection with you and other members of your staff. The results of this inspection are documented in the enclosed report.

The NRC inspectors did not identify any finding or violation of more than minor significance.

This letter, its enclosure, and your response (if any) will be made available for public inspection and copying at http://www.nrc.gov/reading-rm/adams.html and the NRC Public Document Room in accordance with Title 10 of the Code of Federal Regulations (10 CFR), Part 2.390, Public Inspections, Exemptions, Requests for Withholding.

SUMMARY

The U.S. Nuclear Regulatory Commission (NRC) continued monitoring Entergys performance at PNPS by conducting the baseline inspections described in this report 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.

No findings or more-than-minor violations were identified.

PLANT STATUS

The unit began the inspection period at rated thermal power. On January 4, 2018, operators scrammed the unit based on an anticipated loss of offsite power during a winter storm. The unit was returned to rated thermal power on January 11, 2018. On January 25, 2018, operators down powered the unit to 45 percent for a planned repair to a drain valve in the moisture separator drain tank. The operators returned the unit to rated thermal power the same day. On March 4, 2018, operators lowered power to 50 percent to perform a thermal backwash of the main condenser after the March 2, 2018 noreaster. Operators returned the unit to rated thermal power on March 5, 2018. On March 6, 2018, operators shutdown the unit to perform repairs to the fifth point feedwater heater. On March 13, 2018, the site lost all offsite alternating current power during a noreaster while the unit was in cold shutdown, and the startup transformer experienced an electrical fault during the storm. The unit remained in cold shutdown for the remainder of the inspection period to address issues in the switchyard.

INSPECTION SCOPES

Inspections were conducted using the appropriate portions of the inspection procedures in effect at the beginning of the inspection unless otherwise noted. Currently approved inspection procedures 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 inspection procedure requirements most appropriate to the inspection activity were met consistent with Inspection Manual Chapter 2515, Light-Water Reactor Inspection Program - Operations Phase. The inspectors performed plant status activities described in Inspection Manual Chapter 2515, Appendix D, Plant Status, and conducted routine reviews using Inspection Procedure 71152, Problem Identification and Resolution. The inspectors reviewed selected procedures and records, observed activities, and interviewed personnel to assess Entergys performance and compliance with Commission rules and regulations, license conditions, site procedures, and standards.

REACTOR SAFETY

SUMMARY

The U.S. Nuclear Regulatory Commission (NRC) continued monitoring Entergys performance

at PNPS by conducting the baseline inspections described in this report 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.

No findings or more-than-minor violations were identified.

PLANT STATUS

The unit began the inspection period at rated thermal power. On January 4, 2018, operators

scrammed the unit based on an anticipated loss of offsite power during a winter storm. The unit

was returned to rated thermal power on January 11, 2018. On January 25, 2018, operators

down powered the unit to 45 percent for a planned repair to a drain valve in the moisture

separator drain tank. The operators returned the unit to rated thermal power the same day. On

March 4, 2018, operators lowered power to 50 percent to perform a thermal backwash of the

main condenser after the March 2, 2018 noreaster. Operators returned the unit to rated

thermal power on March 5, 2018. On March 6, 2018, operators shutdown the unit to perform

repairs to the fifth point feedwater heater. On March 13, 2018, the site lost all offsite alternating

current power during a noreaster while the unit was in cold shutdown, and the startup

transformer experienced an electrical fault during the storm. The unit remained in cold

shutdown for the remainder of the inspection period to address issues in the switchyard.

INSPECTION SCOPES

Inspections were conducted using the appropriate portions of the inspection procedures in effect

at the beginning of the inspection unless otherwise noted. Currently approved inspection

procedures 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 inspection procedure requirements most

appropriate to the inspection activity were met consistent with Inspection Manual Chapter 2515,

Light-Water Reactor Inspection Program - Operations Phase. The inspectors performed plant

status activities described in Inspection Manual Chapter 2515, Appendix D, Plant Status, and

conducted routine reviews using Inspection Procedure 71152, Problem Identification and

Resolution. The inspectors reviewed selected procedures and records, observed activities,

and interviewed personnel to assess Entergys performance and compliance with Commission

rules and regulations, license conditions, site procedures, and standards.
