Neufe-g 80-11(A) 3/17/80 time 2100 ramped unit down to 250 MWE 33% power due to arcing the 500 KV bus disconnects and generator out put disconnects located in the station switchyard G-108, G56804, G-102 and G-105. At 2343 maintenance was completed in the switchyard, however, the unit was held at approximately 30% power until 3/18/80 at 1745 due to high steam generator cation conductivity. The unit was held at less than full power until 0620 3-19-80 due to unstable steam generator conductivity and an oil leak on "A" feed pump. i 6 b r r = .s s-s
