NRC BEGINS SPECIAL INSPECTION OF ELECTRICAL PROBLEMS 

AT THE POINT BEACH NUCLEAR PLANT

The Nuclear Regulatory Commission has begun a special inspection at the Point Beach Nuclear Power 

Station to look into electrical problems at Unit 1 that led the station to declare an Unusual Event. 

The plant, owned by FPL Energy, is located near Two Rivers, Wisc. 

On Jan. 15, one electrical transformer used by Unit 1 failed, causing a loss of offsite power to vital 

electrical equipment called buses. These buses supply electricity to important safety equipment that would be 

needed to mitigate the consequences of an accident. 

These electrical problems led the plant to declare an Unusual Event, the lowest level of emergency in 

the NRC’s emergency classification system. 

The electrical problems did not impact normal plant operations. Both units remained at full power 

during the event. The station’s emergency diesel generators started and provided back-up power. 

 As was required by the plant’s technical specifications, the utility shut down Unit 1. After the unit’s 

safe shut down, the Unusual Event was terminated. 

The plant was in a stable condition throughout the event. There was no risk to public safety at any time. 

 The NRC staffed the Region III Incident Response Center to monitor the event. NRC staff at the plant 

and in the Region III office monitored the situation around the clock, from the declaration of the Unusual Event 

on the afternoon of Jan. 15 through the evening of Jan. 16, when the event was terminated. 

Both units of the point Beach plant remain in a stable condition. Unit 1 will remain shut down 

until the electrical problems are repaired. Unit 2 is operating at full power. The utility formed a special 

team to investigate the cause of the incident, develop corrective actions and repair problems. 

“Even though the plant operated safely during the Unusual Event and is now in a stable 

condition, the NRC decided to dispatch a special inspection team to Point Beach,” said James Caldwell, 

NRC’s Regional Administrator. “We need to make sure we understand what led to the electrical 

problems at the plant. We also need to have confidence that the utility gains a full understanding of what 

happened and what needs to be done to prevent recurrence of such electrical problems.”
