It looks like the procedure is described here http://download-uk.oracle.com/docs/cd/B10501_01/server.920/a96529/ch10.htm#1010387

The description seems to be a bit shaky. What I would do is set up export tables with the PK of the original table and the NCHAR columns of the original tables. Only then you would be able to 'drop' those columns. This link also describes the procedure to change the NCHAR set of your 9i database, which needs to happen anyway, as your current characterset is not supported.
