• Date due NRC-Date of Occurrence 7/8/81 Time of Occurrence _2355,_ Unit _, 2 Identification and Description _of,_ Occurrence:

During start up, while the unit was ascending to full power, SI 2.1 and the value for R factor were out of limits.

Conditions Prior to Occurrence:

Unit 1 in refueling outage.

Unit 2 at 50%.

Unit 3 at 100%.

Action specified in the Technical Specification Survei"ance Requirements met due to inoperable equipment.

Describe.

Analysis of_ Occurrence.

There was no danger to the health or safety of the public, no release of activity, no damage to the plant or equipment, and no resulting significant t

chain of events.

Cor_rective Action:

Control rod moves in conjunction with R factor setpoint, placed R factor in limits to perform SI 2.1 successfully. STA's were briefed on diose monitoring of R factor during start up.

Failure Data: BFRO-50-260/81018.
