44 47 jThe cause was a burned out coil in solenoid valve SV-624 which supplies control air D:IIJ !for the service water flow contro.l valve for No; 12 CT.CU.

The burned out coil was o:IiJ 1replaced and SP(O) 4.6.2.3.A was performed to confinn operability.

DCR PD-175 has [II)) !been unplemented which provides for improved heat rating solenoids and spare parts o::I3J !kits to be.installed in solenoid valves when repair is requested..
