README file for monthly nuclear operating data. There are 118 files, all 
zipped in the file rr-data.zip. These files came from a Unix system.

Data set consists of 117 separate ASCII files on U.S. nuclear reactor
monthly operating histories over the period 4/75 to 12/94 (start date is
later than 4/75 if plant came online after 4/75 and ending date is earlier
than 12/94 if plant was shut down prior to 12/94). In addition there is a
summary file, NUKESUM.ASC, which provides summary information on
non-time-varying characteristics of 121 U.S. nuclear power plants,
including the 117 plants for which we have data on monthly operating
histories. 

The reactor monthly operating history files (*.mon) have the following 
format:
