7. Downtime for work on D-700 rinse sprayhead resulted in a stream factor penalty of 0.24%.
8. Routine safety disc changeouts on 742 and 745 reactors resulted in a stream factor penalty of 0.23%.
9. Downtime to repair both recovery compressors in the old reactor module resulted in a stream factor penalty of 1.2%.
10. Downtime in the old reactor module to repair a ruptured firewater line resulted in a stream factor penalty of 0.27%.
.11 Downtime in the new reactor module to repair a section of ruptured inert vent header piping resulted in a stream factor penalty of 0.44%.
12. Downtime due to recovery system scheduling conflicts resulted in a stream factor penalty of 2.0%.
13. Downtime due to no place to dump slurry resulted in a stream factor penalty of 0.94%.
Dryers
1. Production was essentially reactor limited in January. Dryers were shut down when possible for energy conservation purposes. The associated stream factor penalty was 16.7%.
2. Routine dryer cleaning resulted in a stream factor penalty of 1.19%.
3. Dryer centrifuge pluggage resulted in a stream factor penalty of 1.87%.
4. Downtime due to bottlenecks in the sifter and pneumatic transfer systems resulted in a stream factor penalty of 0.60%.
5. Downtime due to dryer burner flameouts resulted in a stream factor penalty of 0.37%.
6. Maintenance on various dryer items including centrifuges, exhausters, activators, sifters, etc. resulted in a stream factor penalty of 2.66%.

Monthly Variable Cost Performance
Variable costs for the month were favorable $2.4MM with $2.395MM due to price and $5,0M due to efficiency. Resin variable cost for the month was T9.856/lb. vs the budgeted 27.197</lb.
The $2.395MM favorable price variance was primarily attributed to lower than budgeted pricing for VCM, $2.3MM; and lower than budgeted pricinq in the utilities area, $67.2M.
The $4.6M favorable efficiency variance can be attributed to favorable variances of $3,3M in VCM efficiency, and $61.6M due to lower than budgeted off-grade pro
duction. An unfavorable variance of ($36.2M) in the utilities area related to
cold weather operation offset the favorable variances. VCM efficiency for the month was 1.00815 lbs. VCM/lb. PVC versus the budgeted 1.00860 lbs./VCM PVC.

Energy Performance/Progress
1. Plant energy consumption for the month was 2950 BTU/lb.
2. A total of thirty-five steam lefcks and seven air leaks were repaired during January. In addition, fourteen steam traps were repaired or replaced.
General
1. Packaging for the month totaled 536,205 pounds.
Resin raw material in the 744 account totaled $223M at month end.
Production of 5425 and 5465 was hampered during the month by contamination from the reactors. The probably cause was related to freezing weather when reactors were kept warm with steam injection to the jacket and chem washed frequently. The contamination problem was cleared up the week endinq 1/10/84.
4. Research personnel were on hand supporting troubleshooting activities on a gel/fisheye problem with 5385 in the old module. The probable cause was linked to dirty reactors as a result of diminished chem wash strength.
5. As part of the department's continuing training program, personnel from several shifts attended an in-plant instrumentation seminar by Jim Brown of MED. The remaining shifts wdre scheduled to attend the seminar in early February.
