Subject: RESTART OF UNIT 1                                               

Discussion:

On August 1, 1998, the LaSalle Unit 1 reactor was restarted at 3:39 p.m. 
(CDT) and reached criticality at 9:37 p.m. On August 4, 1998, with the   
reactor at appropriately 100 psig and 340 degree Fahrenheit and while    
testing various systems during the planned 23-day power ascension to full
power, the licensee decided to shutdown the reactor to address equipment 
problems that were identified during the initial startup. Subsequently,  
plant operators completed a reactor shutdown at approximately 5:30 a.m.  
(CDT) on August 4. The licensee will bring the reactor to a cold shutdown
condition and enter the drywell in order to repair two of eight          
intermediate range detectors, the "A" reactor recirculation flow control 
valve, and a source range monitor cable. In addition, the licensee will  
investigate and repair the reactor core isolation cooling trip/throttle  
valve during the shutdown. The licensee plans to restart the reactor on  
August 6, 1998, following the repairs.                                   

Regional Action:

The resident inspectors, augmented by regional inspectors, have monitored
the licensee's activities around-the clock since the initial startup.    
Around-the-clock coverage will be suspended during the shutdown and will 
resume for a portion of the power ascension testing when the unit is     
restarted.
