L 2. Insert amended table 3.5 (page 3.14) in the 1979 Non-Radiological annual report (no change in Table of Contents); delete present table 3.5 in report (page 3.14). Very truly yours, / I 4 ? \\ fh,.hy N'.. B. R.,Sylvis Manager - Nuclear Operations and Maintenance cc: Director, Nuclear Reactor Regulation (17 copies) c/o Distribution.
