SUMMARY
The U.S. Nuclear Regulatory Commission (NRC) continued monitoring the licensees performance by conducting an integrated inspection at Calvert Cliffs Nuclear Power Plant, Units and 2 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 No findings or violations of more than minor significance were identified.
Additional Tracking Items None.
PLANT STATUS
Unit 1 began the inspection period at rated thermal power. On August 4, 2019, the unit was down powered to 78 percent to support main condenser water box cleaning. The unit was returned to rated thermal power on August 5, 2019, and remained at or near rated thermal power for the remainder of the inspection period.
Unit 2 operated at or near rated thermal power for the entire 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 performed plant status activities described in IMC 2515 Appendix D, Plant Status and conducted routine reviews using IP 71152, Problem Identification and Resolution. 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.

INSPECTION RESULTS
Observation: Multiple Instances of Spurious Reactor Protection System Single 71152 Channel Trips The inspectors reviewed the licensee's evaluation and corrective actions associated with multiple instances of spurious reactor protection system single channel trips as documented in AR04179759, AR04179762, AR04179375, AR04179778, and other action requests. The inspectors concluded that the licensee had taken timely and appropriate actions in accordance with the licensee's operating and alarm response procedures, PI-AA-125, "Corrective Action Program Procedure," various revisions, 10 CFR 50, Appendix B, "Quality Assurance Criteria for Nuclear Power Plants," and 10 CFR 50.65, "Requirements for Monitoring the Effectiveness of Maintenance at Nuclear Power Plants." The inspectors reviewed the licensee's cause evaluations associated with the failures and determined the evaluations were adequate and did not identify a common cause between the failures. The inspectors evaluated industry operating experience, vendor recommendations, and the licensee's maintenance rule implementing procedures with regards to the reactor protection system and independently determined that the licensee's maintenance practices are consistent with industry standards and meet regulatory requirements. Based on the documents reviewed and discussions with licensee personnel, the inspectors noted that licensee personnel identified problems and entered them into the corrective action program at an appropriately low threshold.
