Subject: UNIT 1 STARTUP FOLLOWING REFUELING OUTAGE                       

Discussion:

On October 4, 1997, at 2:33 p.m. (CDT), the licensee completed their     
seventh refueling outage for Unit 1 (1RE07).  Major activities associated
with the outage included steam generator inspection, control rod drop    
testing, high-pressure turbine refurbishment, reactor coolant pump motor 
replacement (one motor), vital battery replacement (two banks), and      
refueling.                                                               
                                                                         
The licensee inspected approximately 4800 tubes in each steam generator  
and plugged a total of 154 tubes.  The licensee still meets their current
reactor coolant system flow and volume Technical Specifications.         
                                                                         
The licensee conducted control rod drop tests with the refueled reactor  
at cold and hot conditions.  All control rods met their Technical        
Specification rod drop times and went to rod bottom.  The guide tubes and
cladding in the reload fuel contain ZIRLO.  This change is intended to   
remediate the phenomenon of incomplete rod insertion (IRI) experienced   
with previous STP cores.                                                 
                                                                         
On October 3, 1997, while in Mode 2, the licensee discovered a           
20 drops/min. leak from one incore instrumentation seal table mechanical 
connection.  During further heatup of the RCS, the leakage dropped to    
about 6 drops/min.  The licensee subsequently performed a Furmanite      
repair which stopped the leakage.                                        
                                                                         
On October 6, 1997, a safety relief valve on a moisture                  
separator-reheater unexpectedly opened with the reactor at 74 percent    
power.  The licensee subsequently reduced power to take the turbine      
off-line and affect repairs.  See PN 97-054 for further details.         
                                                                         
The outage lasted about 21 days, 14 hours.
