LaSalle County Station Unit 2 SOR Differential Pressure Switches Level Drop Data NRC Docket No. 50-374
Dear Sir:
Indicated below is the data from the level drop test performed during Unit 2 shutdown for refueling. The operating pressure (950 psig) level drop test was performed January 3, 1987 and the atmosphere pressure (0 psig) level drop test was done on January 5, 1987. The data shown has been corrected to account for drift in the Rosemont transmitters used for reference at each rack.
