-Both units in service with full capable availability. -PREPA called asking if we were still requesting low loads from dispatchers due to wet coal. Basically I told them weather pending, things should be back to normal by late Sunday. However, I also mentioned that we could support the grid with full loads if the need were to arise. -Unit 2 CDS came on-line much easier than before, we experienced only one Opacity exceedances at 2 1 4 % Some differences utilized; we had at least one High level alarm on a Dosing Valve hopper. We suspect that more high levels, the more ash available, which allows us to delay the start of the rotary valves. Also, CDS temperature was forced to approximately 175F (Cooling Water Control Valve atO%). At this point the Temperature Control Valve was placed at 30%, and then in automatic with the temperature set point at 152F. This provided a stable progression from 175Fto the normal operating temperature (NOT), no swinging up and down and around NOT. -We did encounter problems with elevated vibrations on unit 2. An initial roll up using only three steam control valves resulted in a Turb. Trip due to high vibrations on Gen DE Bearing Once we were loaded we again had elevated vibrations at approximately 145 mw. We went up 5 mw in load and vibrations levels came down. Later, we went up an additional 10 mwfor a total of 160 mw. Brg 1 left or x (max 7.59 mils) and Gen DE Brg (3) left or x (max 6.4 mils) went up again; however, after 5-10 minutes they both came down Every now and then the Gen DE Brg 3 goes into alarm status (which is a known issue). -Problems with bring U2 Coal Feeder A on line. Apparently the Speed sensor was previously damaged, -Cyclone expansion joint temperature measurements; Cyclone inlet had the highest at 232F -Hyd lime measurements

-Unit 2 is in Coordinated Control and full availability. -U2 Reheat Ash Control Valve operation became irratic, changing values randimly, I&E performed troubleshooting, valve was cycle several times and was returned to service. No real cause for problem was identified. -U2 Rapper program changed from Program 6 to Program 1, Opacity reading improved. -Raised CDS temperature from 167 to 169F, slight rise in Opacity reading <1. -U2 Hydrated Lime Injection System problems, I&E and Maint/Services corrected problem. Unit One -Continue Clean-out of RH FBHE -Worked on FBHE Air Plenums, nozzle cleaning. -Unit 1 Turbine oil sump cleaned out & suction filters; basket strainer at enterance is the only remaining item to be cleaned. -Combustor clean-out -IT Thorpe working on coal inlet modifications -Re-packing Int FBHE to Combustor expansion joint.

-Unit one shutdown -Unit 2 in Coordinated Control, full availability, full load. -Better pipe supports used on U2 FBHE Acoustic system, Fin and Int readings at 0.5; RH is at 0.83. -Performed several operational tests on U2 CDS/ESP. -Raised CDS temperature to 175F. As temperature rose, SO2 readings became elevated Adjustments were made; however, one exceedance occurred at 1400 hrs, 55.3 Ibs/hr. -Changed rapper programming, slowed down back six rows, paired so that the rapping times are 5 min, 10 min, and last pair of rows at 15 min. -High level alarms came in on U2 ESP hoppers 430's, 440's, and 450's. Performed several evolutions in attempts to control opacity: performed dump sequences; changed rapper program to what it was before; brought CDS temp backdown to 169F, used best water quality, and T/R's2-4, 2-5, 2-7, and 2-8 were re-set several times. Opacity level was spiking with wild abandonment. Several opacity exceedances: 22 1% 1618 hrs; 26.7% 1630; 27.4% 1642; 20.9% 1648. -U1 RH cyclone inlet only cyclone access open (Scaffolding) all others cleaned, inspected and closed -U1 air slides cleaned, only areas left are back end (beneath 450's) -U1 ESP hoppers cleaned. Ongoing work on hoppers 410A and 400's prevented their cleaning.
