==Dear Mr. Kingsley:==
 
On August 17,1995, the NRC issued Generic Letter (GL) 95-07, " Pressure Locking and Thermal Binding of Safety-Related Power-Operated Gate Valves," to request that licensees take actions to ensure that safety-related power-operated gate valves that are susceptible to pressure locking or thermal binding are capable c' 9erforming their safety functions.
In a letter of February 13,1996, Commonwealth Edison Company submitted its 180-day response to GL 95-07 for LaSalle County Station, Units 1 and 2.
