YEAR 1980 DATE July 11.1980 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 was re. vised to clarify switch operation and the instrument technician s

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%.
