• ML19246A776 - LER 78-090/03X-1 on 780919:during critical steady state operation,axial flux difference deviated more than -5% from target.Caused by rapid load reduction necessitated by clogging strainer.Pumps shifted. (3 page(s), 7/2/1979)
• ML19246A777 - LER 79-030/03X-1 on 790308:nonconservative gain setting on delta-flux signal feeding overpower delta T protection circuitry observed.Caused by improper setting of delta-flux gain.Signal recalibr. (2 page(s), 7/2/1979)
• ML19246A778 - LER 79-040/03X-1 on 790326:discovered nonconservative output of upper/lower flux signal summing amplifier in overpower delta T protection circuitry.Caused by instrument drift.Summing amplifier card replaced & delta T recalibr. (2 page(s), 7/2/1979)
