wns dur ing the report period. In addition, it should be the source of explanation of significant dips in average power levels (Appendix B). Each significant reduction in power level (greater than 20% reduction in average daily power level for the preceding 24 hours) should be noted, even though the unit may not have been shut down completely) For such reductions in powe± lew', the duration should be listed as zero, the method of reduc tion should be listed as 4 (Other), and the Comments column should explain.
