Only 3A & 3D TFP1S38S = T 4kV bus are now available from 3A EDG. 3-EOP-E-3 is performed performed to cooldown andand depressurize depressurize the the ROS RCS to stop primary-secondary leak to stop leak flow.

Turnover: Equipment OOS: 3B EDG due to failed fuel pump (OOS 2 days; next 0-OSP-023.3 AU 1 &
Att 1 & 9 in 4 hrs); B B AFW Pump due to bearing failure (OOS 4 hrs; ETR 24 hrs; both trains verified operable);
3B CSP due to failed 1ST -low - low discharge pressure (OOS 12 12 hr; ETR 36 hr)
Perform monthly surveillance on 3A ECC per 3-OSP-055.1 3-0SP-055.1 section 7.1 immediately after shift turnover. 1ST and remote valve position verification not required.
Known tube leak in 3A S/G (2 gpd) - unchanged for last week. Chemistry samples are being taken per 3-ONOP-071 3-0NOP-071.2, .2, Attachment 1. The current sample, just completed indicates no MOV-3-1 403 remains open at management direction due to small significant change in leak rate. MOV-3-1403 size and stability of tube leak rate.

immediate actions of 3-EOP-E-0 are performed.
6 (M) ALL When 3B RCP is tripped, 3B 4kV bus is lost and a large break LOCA occurs.
TFE2Z51S ==TT (contd from (cont'd An automatic SI occurs but train A sequencer fails. Train A ECCS equipment event event 5) must be manually started. The crew completes 3-EOP-E-0 and transitions to TvHHCLB=0.1 TVHHCLB = 0.1 (C) ALL applicable FRPs followed by 3-EOP-E-1.
TFQ634AF == T 6a Once CSFSTs are monitored for implementation, if containment pressure is still above 20 psig, the crew immediately transitions to 3-EOP-FR-Z.1 if no higher red or orange path exists.
6b SROIRO (C) SRO/RO 3-EOP-E-1 is entered after which 3A RHRP trips. Since neither RHRP is TFM1D3AT=T TFM1D3AT =T running, transition is made to 3-EOP-ECA-1.1. Measures are taken to minimize the loss of RWST inventory.
