Summary of U-l operating Experience April 1988 The Unit began the month at the 97% derated maximum for out of service 2nd Stage MSR's (leakage).
Reduced power (1500) for phase isolation testing.
Remained at 93%
until 4/7/88 at 1300 when power was reduced to 50% for SGFP test-ing.
Unit returned to 97% (SAM) on 4/8/88.
Began ramp-down for shutdown at 1300.
Unit removed from the grid at 0152, 4/9/88 for Refuel-ing/ILRT Scheduled Outage.
Unit remained off-line through the end of this reporting period (scheduled to return on or about May 29th).

Summary of U-2 Operating Experience April 1988 Date Time Event Descriotion 4/1 0000 Unit began shutdown in th'a Pre-Summer General Maintenance Outage (day #35 of 35).
The original 23 day schedule was extenced (primari-ly) due to 2-FW-130/133 replacements and FWH 25A/B associated repairs / velds /RTs (radio-graphs).
4/1 1821 Paralleled unit to grid, began power ramp-up.
4/2 0200 Held at 85% for STP-M-213; at 0845 held power to investigage #4 bearing on the Main Turbine.
By 1020, began ramp up to 100%.
4/3 1455 Reduced power to clean waterboxes, returned to full power at 2020.
4/27 0850 Unit manually tripped when S/G levels decreased
- lost #21 SGFP.
4/30 2400 Unit renained shutdown for repairs to #22 S/G Main Steam hanger.
Summary of U-2 Operating Experience April 1988 The Unit began this reporting period shut down.
On April 1 at 1821, paralleled Unit to grid; began power ramp-up.
Held at 85% power (0200, 4/2/88) for STP testing, STP-M-213; at 0845, while investigating #4 Main Turbine bearing temperature; @
1020 began ramp-up.
At 1455, (4-3-88) reduced power to clean waterboxes (returned at 2020).
At 0850 on April 27th, Unit was manually tripped when S/G levels decreased too low (due to loss of #21 SGFP).
Stayed shutdown until May 2.
