Additional Tracking Items

Type Issue Number Title Report Section Status LER 05000321/2020-001-00 LER 2020-001-00 for Edwin 71153 Closed I. Hatch Nuclear Plant Unit 1, 1A EDG Inoperable Due to Water in the Day Tank

PLANT STATUS

Unit 1 began the inspection period at 100 percent rated thermal power (RTP). On January 9, 2021, the unit was down powered to 70 percent RTP to perform a sequence exchange and turbine valve testing and on January 10, 2021, the unit was returned to 100 percent RTP. On March 20, 2021, the unit was down powered to 70 percent RTP to perform a sequence exchange, scram time testing, turbine valve testing and attempted to repair a steam leak in the condenser bay and on March 21, 2021, the unit was returned to 100 percent RTP. On March 22, 2021, the unit was down powered to 93.5 percent RTP for rod pattern adjustment and was retuned to 100 percent RTP on the same day and operated there for the remainder of the inspection period.

Unit 2 began the inspection period at 91 percent RTP in its end cycle coast down for the winter refueling outage. On January 7, 2021, the unit was down powered to 70 percent RTP to remove the fourth stage feed water heaters from service, this was to achieve an increase in RTP due to removing feed water heating. On January 7, 2021, the Unit returned to 97 percent RTP and continued the end cycle coast down to the refueling outage. On February 8, 2021, the operators shut down the unit for the scheduled refueling outage. The unit was restarted on March 7, 2021 and reached approximately 100 percent RTP on March 13, 2021. On March 19, 2021, the unit was down powered to 98 percent RTP to perform the final rod pattern adjustment after startup was returned to 100 percent RTP on the same day. On March 26, 2021, the unit was down powered to 93 percent RTP due to isolation of the fourth stage B high pressure feed water heater and was returned to 100 percent RTP on March 29, 2021 and operated there 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 Disease 2019 (COVID-19), resident 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; conducted plant status activities as described in IMC 2515, Appendix D, Plant Status; 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.

71152 - Problem Identification and Resolution

Annual Follow-up of Selected Issues (IP Section 02.03) (1 Sample)

The inspectors reviewed the licensees implementation of its corrective action program related to the following issues:

(1) Root Cause Determination Report 278526, Unplanned Power Changes Performance Indicator Low Margin Hatch Unit 1 during 2020, was reviewed by inspectors, on March 15, 2020.

71153 - Follow-up of Events and Notices of Enforcement Discretion Event Report (IP Section 03.02)

The inspectors evaluated the following licensee event reports (LERs):

(1) LER 05000321/2020-001-00, 1A EDG Inoperable due to water in day tank (ADAMS Accession No. ML20345A083) on December 10, 2020. The inspection conclusions associated with this LER are documented in Inspection Report 05000321/2020002 under Inspection Results Section

INSPECTION RESULTS

Licensee-Identified Non-Cited Violation 71124.07 This violation of very low safety significance was identified by the licensee and has been entered into the licensee corrective action program and is being treated as a non-cited violation, consistent with Section 2.3.2 of the Enforcement Policy.

Violation: 10CFR20 1406(c) requires in part, that licensees, to the extent practical, conduct operations to minimize the introduction of residual radioactivity into the site, including the subsurface. Contrary to this requirement, on February 1, 2021, as the result of the licensee's failure to perform, to the extent practical, maintenance activities on the unit two condensate storage tank transfer pump moat to minimize the introduction of residual radioactivity to the site subsurface, leakage of elevated tritium activity from the moat was detected in an adjacent ground water monitoring well.

Significance/Severity: Green.

Corrective Action References: CR
