Following is a list of off-line outages at each',o'f the' Blungi,c); and Robinson nuclear units for the years 1978 through 1983. Included on;this list is a designation of the outage type. The key to this list is as follows:
F = Forced S = Scheduled / Maintenance SP = Scheduled / Planned A Forced Outage is defined as the occurrence of a component failure, or other condition, which requires that the unit be removed from service immediately or up to and including the very next weekend. A Maintenance Outage is the removal of a unit from service to perform work on specific components which could have been postponed past the very next weekend. This is work done to prevent a potential forced outage and which could not be postponed from season to season. The Planned Outage is the removal of a unit from service for inspection and/or general overhaul of one or more major equipment groups. This is work which is usually scheduled wellin advance.
