Electric Institute (EEl) definitions of "Forced Partial Outage" and "Scheduled Partial Outage." For these terms, EEl uses a change of 30 MW as the break point. For larger power reactors, 30 MW is too small a change to warrant explanation. required to be initiated by no later than the weekend following discovery of an off-normal condition. It is recognized that some judgment is required in categori zing shutdowns in this way. In general, a forced shut down is one that would not have been completed in the absence of the condition for which corrective action was taken. Duration. Self explanatory. When a shutdown extends beyond the end of a report period, count only the time to the end of the report period and pick up the ensuing down time in the following report periods.

Categorize by letter designation in accordance with the table appearing on the report form. If category H must be used, supply brief comments. Method of Shutting Down the Reactor or Reducing Power. Categorize by number designation in accordance with the table appearing on the report form. If category 4 must be used, supply brief comments. Corrective Actions/Comments.
