SUMMARY

The U.S. Nuclear Regulatory Commission (NRC) continued monitoring the licensees performance by conducting an integrated inspection at Duane Arnold Energy Center, 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

The unit began the inspection period at rated thermal power. On November 2, 2019, the unit was down powered to 60 percent power for a control rod sequence exchange. The unit was returned to full power on November 3, 2019 and remained at or near rated thermal power for the remainder of the inspection period.

INSPECTION SCOPES

INSPECTION RESULTS

Observation: Addressing Risk and Risk Communication 71152 In August of 2019, the inspectors identified a negative trend in addressing risk and risk communication. Examples include:

• During the 2018 refueling outage, the risk associated with work on the condensate demineralizer instrument air filter housing was not communicated to the workers. This resulted in the workers improvising a repair to the severely damaged and degraded condensate demineralizer air filter housing. The improvised repair failed while the plant was at full power. Demineralizer flow was lost. Subsequently, operators manually scrammed the reactor due to rapidly lowering reactor water level. The inspectors documented this event in Inspection Report 05000331/2019002 and the licensee reported this as detailed in License Event Report 05000331/2019-001-00.

• In July 2019, the licensee did not adequately communicate identified risks associated with fuel mixture adjustments on the diesel fire pump engine during a maintenance inspection. The licensee did not provide adequate oversight over an inexperienced vendor technician during the fuel mixture adjustment portion of the inspection. The technician made inappropriate adjustments and created an over rich fuel mixture that deposited combustibles in the exhaust line. This resulted in an exhaust line fire that spread to the non-safety related side of the pump house roof. The inspector evaluated this minor event during the 3rd Quarter of 2019.

• Other minor examples included an inadequate brief for work on the well water flow recorder and an inadequate brief associated with taking an oil sample on an instrument air compressor. In the first example, a technician inadvertently allowed a loose wire to make contact which blew a fuse in the recorder circuit. This resulted in well water isolating from loads and unplanned entries into abnormal and emergency operating procedures. In the second example, an operator unfamiliar with the sample location breached the instrument air system causing a control room alarm for low instrument air pressure.

The inspectors monitored licensee actions to address risk and risk communication. The inspectors observed increased emphasis on risk communications during plan-of-day meetings and shop briefings. Duane Arnold Nuclear Assurance observed communications and wrote action requests to address substandard communications. This resulted in discussions that increased sensitivity to the importance of addressing risk and risk communication. The inspectors concluded that the licensee's increased emphasis on risk and risk communication resulted in improvements in station performance and a reduction in near miss occurrences.

Observation: Integrated Process Radiation Monitor Maintenance Issues and 71152 Post Accident Sampling Early in 2019, the inspectors observed an increasing trend in process radiation monitor issues. The inspectors noted several minor equipment and human performance related issues.

Equipment related issues, the result of component aging and spare part availability, included:

• reoccurring off-gas detector failure alarms

• multiple momentary radiation detector alarms with nothing recorded

• control building intake radiation monitor trouble alarms and spurious standby filter unit actuations

• recurring fuel pool exhaust radiation monitor downscale alarms

• incorrect background on effluent ventilation radiation monitor Human performance issues, the result of inadequate work focus in the field or procedure unfamiliarity, included:

• incorrect background programmed into radiation monitors

• using incorrect background values while calibrating a reactor building vent shaft radiation monitor

• mispositioning components when calibrating effluent radiation monitors

• lack of familiarity with emergency alternate sampling procedures for when accident range process radiation monitors are unavailable The inspectors determined that the equipment related issues identified in this inspection sample, although many, were minor and adequately addressed. The inspectors determined that the human performance issues identified in this sample were adequately addressed.

The inspectors evaluated the licensee's readiness to do post-accident manual sampling, analysis and assessment of offsite releases with a concurrent loss of accident range effluent radiation monitors. The inspectors reviewed procedures, training records, walked down sample locations with technicians, and conducted interviews with supervisors and technicians. The inspectors concluded for the scenarios discussed, licensee staff have the training and supervisory skills to collect, analyze and assess post-accident releases with post-accident effluent radiation monitors unavailable.
