! COMPLETED BY W. R. MADISON -
[ 80-14'(H)6/6/80 Time: 1750. Decreased turbine power to 200 MWe to
- perform secondary side Boric Acid Soak of the steam generators ,
l per 1-PT-72.4. This soak was performed per a Westinghouse recommen-
! dation in an attempt to minimize S/G tube denting. .
l-80-15 (G) 6/12/80' Time: 1847. An instrument technician was performing 1-PT-44.4.1 (0verpressurization Protection Instrumentation Functional Test with PORV Operability Not Required) when he accidently opened
- the wrong switch in the protection and control racks. This l resulted in a steam flow / feed flow mismatch and low Channel I S/G level, causing a turbine trip / reactor trip. The periodic test s
was re. vised to clarify switch operation and the instrument technician was reinstructed.
80-16 (A) 6/14/80 Time: 1200. Decrease reactor power to 40% to al bw contain-ment entry to repair A S/G LT-1474 root valve. The root i..ve had a body to bonnet leak resulting in an erroneous level signal being sent to the protection circuit. The valve was firminited, leak stopped, and power was again escalated to 100%.
80-17'(A) 6/18/80 Time: 0905. An instrument technician was working in process rack no. 6. When.he completed his work he closed the rack door which jarred a loose jumper on a process card. This resulted in a steam flow / feed flow mismatch and A S/G low level causing a turbine trip /
reactor trip ~. The, card with the loose jumper was replaced. A random inspection of process cards will be performed to identify any other loose jumpers.
80-18 (H) 6/26/80 Time: 1422. . An instrument technician was calibrating N43 and a spurious spike occurred on one of the other two channels. This
, resulted in a overtemperature AT reactor trip _. Subsequent to this trip setpoint checks were performed on both suspected channels with no defects or spikes noted. Prior to reactor startup a problem developed in Channel II and a faulty card was' changed out. Test recorders were installed and the reactor'was started up. The test recorder-indicated a fluctuating signal from the TAVE circuit for
=
Channel I. A faulty card was changed with no further problems noted.
80-19. (A) 6/27/80 : Time,: 2315. ' Decreased power and took generator off-line ,
when a broken air line was discovered on one of the actuating ,
_ cylinders for B Main' Steam Trip ~ Valve. ' The broken air line was '
replaced and the generator placed on the 'line. Power was escalated to 100%. -
