• ML112900691 - LER 80-002/01T-0:on 800225,during refueling outage,local leak rate for A0-2-86A outboard MSIV exceeded Tech Spec acceptance criteria.Caused by poppet not seating properly. Poppet machined & stem replaced. (2 page(s), 4/8/1980)
• ML112900693 - LER 80-003/01T-0:on 800225,during refueling outage,local leak rate for A0-2-86D,outboard MSIV,exceeded Tech Spec acceptance criteria.Caused by lapping of main seat so that poppet did not seat properly.Poppet machined. (2 page(s), 4/8/1980)
• ML112900695 - LER 80-004/01T-0:on 800223,during local leak rate testing, HPCI-9 turbine exhaust line check valve found leaking in excess of Tech Spec acceptance criteria.Caused by leakage past body-to-seat ring threaded joint. (2 page(s), 4/8/1980)
• ML112900697 - LER 80-005/01T-0:on 800303,during local leak rate testing, XP-6 standby liquid control outboard isolation valve,found leaking in excess of Tech Specs.Caused by accumulation of scale on seat.Replaced valve. (2 page(s), 4/8/1980)
