New Hampshire Yankee has completed a' substantial portion'of the programmatic enhancements originally scheduled for completion by May 1, 1990. Adminirtrative and operating procedures have been revised. These revisions established requirements-for RCS temperature and level' monitoring,-.

This analysis will provide supporting.information for the remaining-programmatic enhancements.
